Surgical sponge inventory rack

A surgical sponge inventory rack includes a vertical mounting rod, a laterally extending sponge bag holder connected to the mounting rod, and a sponge bag supported on the sponge bag holder. The sponge bag includes a pocket configured to receive and display a surgical sponge. The sponge bag holder including a plurality of support members. The support members are shiftable relative to one another to transition the sponge bag holder between a collapsed configuration and an expanded configuration. At least one of the support members extends in the lateral direction past another of the support members when the sponge bag holder is in the expanded configuration. The support members collectively present a depth in a fore-and-aft direction that is transverse to the lateral direction and transverse to the vertical direction. The depth is at least substantially constant as the sponge bag holder transitions between the collapsed and expanded configurations.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a surgical sponge inventory rack. Such a rack is conventionally used by a member of a surgical team to visually account for all surgical sponges used during a surgical procedure.

2. Discussion of the Prior Art

Those of ordinary skill in the art will appreciate that surgical sponge inventory racks provide a simple visual means of accounting for surgical sponges before, during, and/or after a surgical procedure is performed. Sponge counts may occur prior to a procedure to determine an initial baseline count, at one or more points during a procedure (e.g., prior to closure of a cavity within a cavity), just prior to the final step of the procedure (e.g., just prior to skin closure), and/or as part of relief procedures of a member of a surgical team (e.g., during a shift change for an attending surgical nurse).

Due to space constraints within often crowded operating rooms, surgical sponge inventory racks conventionally present limited width and depth dimensions. As a result, the number of readily visible sponges is often severely limited. More particularly, used sponges are conventionally placed in “sponge counter bags” comprising a plurality of transparent or translucent pockets attached to a flat sheet. If more sponges are necessary for a procedure than can be individually placed in respective ones of the pockets of a single bag, multiple bags must be used. As will be discussed in greater detail below with reference to specific prior art embodiments, the bags may be placed side by side, on the front and back of the rack, and/or stacked in an overlapping manner, potentially resulting in one or more bags (and in turn, sponges) being obscured from view unless additional steps are taken to expose them during each sponge count. Such steps may be time-consuming and increase the potential for erroneous counts.

SUMMARY

According to one aspect of the present invention, a surgical sponge inventory rack comprises a mounting rod extending in a vertical direction, a sponge bag holder connected to the mounting rod and projecting relative thereto in a lateral direction that is transverse to the vertical direction, and a sponge bag supported on the sponge bag holder and including a pocket configured to receive and display a surgical sponge. The sponge bag holder includes a plurality of support members. The support members are shiftable relative to one another to transition the sponge bag holder between a collapsed configuration and an expanded configuration. At least one of the support members extends in the lateral direction past another of the support members when the sponge bag holder is in the expanded configuration. The support members collectively present a depth in a fore-and-aft direction that is transverse to the lateral direction and transverse to the vertical direction. The depth is at least substantially constant as the sponge bag holder transitions between the collapsed configuration and the expanded configuration.

According to another aspect of the present invention, a method of storing and displaying used surgical sponges on a surgical sponge inventory rack is provided. The surgical sponge inventory rack includes a mounting rod extending in a vertical direction and a sponge bag holder connected to the mounting rod. The sponge bag holder includes a plurality of support members. The method comprises the steps of: (a) shifting the support members relative to one another in a lateral direction that is transverse to the vertical direction, such that at least one of the support members extends in the lateral direction past another of the support members, to transition the sponge bag holder from a collapsed configuration to an expanded configuration; (b) hanging a sponge bag from one of said support members such that a pocket of the sponge bag is visible on a front side of the surgical sponge inventory rack; and (c) placing a used sponge into said pocket such that the used sponge is visible from the front side of the surgical sponge inventory rack.

According to yet another aspect of the present invention, a bag holder for use in a surgical sponge inventory rack includes a vertical mounting rod. The bag holder is connectable to the mounting rod and is configured to support sponge bags in which one or more surgical sponges are held. The bag holder comprises a plurality of support members each configured to support a sponge bag thereon. The support members are shiftable relative to one another so as to transition the bag holder between a collapsed configuration and an expanded configuration. At least one of the support members extends in a lateral direction past another of said support members when the bag holder is in the expanded configuration. The support members collectively present a depth in a fore-and-aft direction that is transverse to the lateral direction. The depth is at least substantially constant as the bag holder transitions between the collapsed and expanded configurations. A second one of the support members is slidably intercoupled with a first one of the support members. A third one of the support members is pivotable relative to the second one of the support members. A fourth one of the support members is slidably intercoupled with the first one of the support members. The first one of the support members is disposed laterally between the second one of the support members and the fourth one of the support members when the bag holder is in the expanded configuration.

The drawing figures do not limit the present invention to the specific embodiments disclosed and described herein. While the drawings do not necessarily provide exact dimensions or tolerances for the illustrated components or structures, the drawings are to scale with respect to the relationships between the components of the structures illustrated in the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention is susceptible of embodiment in many different forms. While the drawings illustrate, and the specification describes, certain preferred embodiments of the invention, it is to be understood that such disclosure is by way of example only. There is no intent to limit the principles of the present invention to the particular disclosed embodiments.

Furthermore, unless specified or made clear, the directional references made herein with regard to the present invention and/or associated components (e.g., top, bottom, upper, lower, inner, outer etc.) are used solely for the sake of convenience and should be understood only in relation to each other. For instance, a component might in practice be oriented such that faces referred to as “top” and “bottom” are sideways, angled, inverted, etc. relative to the chosen frame of reference.

Conventional Designs

With initial reference toFIGS. 1A and 1B, a prior art surgical sponge inventory rack10is illustrated. The rack10includes a base12, a mounting rod14, a bag holder16, and a top18. The base12includes a plurality of radially extending legs20each supported by a respective caster22. The casters22enabling rolling of the entire rack10and thereby facilitate easy positioning of the rack10. The mounting rod14extends vertically upward from the base12and is centered relative to the legs20. The bag holder16is fixed to the mounting rod14. The top18is disposed at an upper end24of the mounting rod and includes a plurality of radially extending arms26. Those of ordinary skill in the art will appreciate that the base12, rod14, and top18cooperatively make up a traditional mobile IV stand.

The bag holder16includes a frame28and front and rear pairs of bag hooks30and32, respectively. A replaceable package34for containment and dispensation of unused surgical sponge bags is supported within the frame28. A sponge bag36hangs from the front bag hooks30so as to present ten (10) readily visible pockets38. The rear bag hooks32are shown empty in the illustrated embodiment. However, during the course of a surgical procedure, should the illustrated bag36become full of used sponges, a second bag might be hung from the rear hooks32to provide additional pockets, and/or bags might be stacked on top of one another (i.e., layered in an overlapping manner). Thus, the illustrated bag36might eventually be covered by another bag, making the sponges received in the pockets visible only upon lifting of the overlying bag.

The rack10ofFIGS. 1A and 1Benables unobstructed visibility of only (10) sponges on each side thereof and only twenty (20) total sponges before overlapping of bags is necessary. Due to space constraints, limited time, and/or other factors, it may be undesirable for surgical staff to be required to walk around the rack10to see both front and rear bags in order to count more than ten (10) surgical sponges. Similarly, it may be undesirable to require “flipping through” layers of bags in order to obtain a count of used sponges that exceeds ten (10).

Turning toFIGS. 2A and 2B, a second prior art sponge inventory rack110is illustrated. The second prior art rack110differs from the first prior art rack10primarily in the configuration of the bag holder112. More particularly, the bag holder112of the rack110includes a frame114, two (2) pairs of front bag hooks116and118, and two (2) pairs of rear bag hooks120and122. Thus, double the number of bags124are visible on each side of the rack110compared to the rack10of the first prior art embodiment, and stacking or overlapping of bags124is also necessary only after twice the number of sponges have been used.

Although the rack110is an improvement over the rack10, the deficiencies described above with regard to the rack10nevertheless apply.

Design 1: Slidable and Pivotable Flat Plate Support Members

FIGS. 3 and 4illustrate front and rear perspective views of a first embodiment of the present invention, in a fully expanded configuration. (Partially expanded/contracted/collapsed and fully contracted/collapsed configurations will be discussed in greater detail below.) More particularly, a surgical sponge inventory rack210is provided. The rack210includes a base212, a mounting rod214, a bag holder216, and a top218. As will be discussed in greater detail below, the bag holder216is shiftable between fully contracted and fully expanded configurations corresponding to so-called fully contracted and fully expanded configurations of the rack210as a whole.

In a preferred embodiment, the base212, the mounting rod214, and the top218are multi-purpose components capable of playing alternative roles within a medical context. For instance, the illustrated base212, mounting rod21, and top218are additionally suitable for use as part of a mobile IV pole or stand, etc.

The base212includes a plurality of radially extending legs220each supported by a respective caster222. The mounting rod214extends at least substantially vertically and most preferably fully vertically upward from the base212and is centered relative to the legs220. That is, the legs220each extend radially outwardly from the mounting rod214. The top218is disposed at an upper end224of the mounting rod214and preferably includes a plurality of radially extending arms226.

In a preferred embodiment, as illustrated, the rod214is a telescoping rod214including at least a larger-diameter base member228and a smaller-diameter upper member230. A collar232is preferably provided to tighten or loosen a juncture234between the members228and230and to facilitate or restrict, and ultimately at least substantially eliminate, relative axial motion between the members228and230. It is permissible according to some aspects of the present invention, however, for a non-telescoping rod to be provided.

The bag holder216preferably includes a plurality of support members236a-e; a bracket238supporting the support members236a-e; and a clamp240supporting the bracket238. The clamp240includes a band242at least in part encircling the rod214and a pair of adjustable keys244extending through the clamp240and configured to shift radially inwardly or outwardly to engage or disengage from the rod214. The keys244and the band242thereby tighten or loosen a juncture246between the bag holder216and the rod214(and most preferably, the base member228thereof) to facilitate or restrict, and ultimately at least substantially eliminate, relative motion between the bag holder216and the rod214. The height of the bag holder216can thereby be readily adjusted, and subsequently fixed. Undesirable rotation of the bag holder216around the rod214is also at least substantially prevented. It is permissible according to some aspects of the present invention, however, for a non-positionally adjustable bag holder to be provided.

The bag holder216is preferably formed of metal, although other materials fall within the scope of the present invention.

The bracket238preferably extends forward from the rod214such that the support members236a-eare disposed on a front side of the rack210.

In a preferred embodiment, a plurality of bags248a-e, each including respective pluralities of pockets250a-e, hang from respective ones of the support members236a-e. Most preferably, each of the bags248a-ehangs from a front side of the rack210such that the pockets250a-eare all visible from a single position (e.g., a vantage point in front of the rack210). In the illustrated embodiment, for instance, five (5) bags248a-e, each including ten (10) respective pockets250a-e, are simultaneously visible from a single position to enable an unobstructed count of up to fifty (50) used sponges, assuming only one sponge is place in each pocket250a-e.

Preferably, each support member236a-eincludes a respective pair of hooks252a-eprojecting upwardly therefrom when the support members236a-eare in an expanded configuration. Each hook252a-epreferably includes a base254a-eand a head256a-e, with each head256a-erestricting slippage of one or more corresponding mounted bags248a-eoff of the corresponding support member236a-e.

Most preferably, the heads256a-eare each in the shape of a triangle. The bases254a-eare each preferably in the shape of rectangle. The hooks252a-eare therefore generally in the shape of upwardly pointing arrows when the bag holder216is in a fully expanded configuration. A variety of hook shapes fall within the scope of the present invention, however.

The support members236a-emost preferably include a foundational support member236a, a pair of slidable support members236band236c, and a pair of pivotable support members236dand236e.

Thus, five (5) support members236a-eare provided, with each of the support members236a-emost preferably configured to display one (1) bag248a-ein a substantially unobstructed manner.

Configurations that do not achieve one-to-one correspondence between support members and bags are also permissible according to some aspects of the present invention. For instance, one or more of the support members might be configured to cooperatively support a single bag (e.g., a single bag might hang from a first hook provided by first support member and a second hook provided by an adjacent support member). Stacking of bags, as discussed above with regard to the prior art, may also occur; but a substantially complete “top” bag should always remain visible when hanging from its respective support member, when the bag holder (or, in a more general sense, the rack) is in a fully expanded configuration. “Substantially” as used in the present sense should be understood to mean simply that any overlap that occurs between adjacent bags is small enough that any sponges held in said bags are readily visible for easy and unambiguous counting.

Although five (5) support members236a-eare provided in the illustrated embodiment, it is noted that more or fewer support members may be provided without departing from the scope of some aspects of the present invention.

The foundational support member236ais preferably centered on the rod214so as to extend laterally therefrom, equidistantly in two (2) opposing directions. As will be discussed in greater detail below, the foundational support member236aas a whole is also preferably radially symmetrical (i.e., formed by a pair of identical halves offset one hundred and eighty (180) degrees from each other). The foundational support member236apresents opposite longitudinal ends258.

The slidable support members236band236care preferably identical to each other and each preferably feature mirror symmetry. The slidable support members236band236ceach present a pair of longitudinal ends260. As best shown inFIG. 5, the proximal or inner ones of the ends260of each of the slidable support members236band236cpreferably each overlap an adjacent one of the ends258of the foundational support member236awhen the rack210is in the expanded configuration. An overlapping region262is thus defined between the support members236aand236b, and also between the support members236aand236c.

The slidable support members236band236care preferably oriented so as to collectively (i.e., cooperatively) present radial symmetry. That is, whereas the slidable support member236bmay be interpreted as facing forward, the slidable support member236cmay be interpreted as facing backward.

The pivotable support members236dand236eare preferably identical to each other but do not feature mirror symmetry. However, the pivotable support members236dand236eare preferably oriented so as to collectively present radial symmetry. That is, whereas the pivotable support member236dmay be interpreted as facing forward, the pivotable support member236emay be interpreted as facing backward.

The pivotable support members236dand236eare preferably the distalmost or outer of the support members236a-ewhen the rack210is in the expanded configuration. More particularly, each pivotable support member236dand236epreferably presents pair of longitudinal ends264. As best shown inFIG. 5, the proximal or inner ones of the ends264of each of the pivotable support members236dand236epreferably each overlap an adjacent one of the ends260(i.e., a distalmost or outer one of the ends260) of the adjacent slidable support member236bor236c, respectively, when the rack210(or, alternatively stated, the bag holder216) is in the expanded configuration. An overlapping region266is thus defined between the support members236band236d, and also between the support members236cand236e.

Interaction of the various support members236a-ewill be discussed in greater detail below, after individual structures of the support members236a-eare further described.

As best shown inFIGS. 9 and 10, the foundational support member236apreferably includes a laterally extending body268presenting the aforementioned ends258. Each of the hooks252apreferably projects vertically upward from the body268when the rack210is in the fully expanded configuration. The hooks252aare preferably integral with and, more particularly, unitarily formed with, the body268, although non-integral formation is permissible. The hooks might, for instance, be adhered, latched, welded, or otherwise attached to the body.

The bracket238is preferably unitarily formed with the body268, with the clamp240in turn being unitarily formed with the bracket238. Non-unitary configurations fall within the scope of the present invention, however.

The body268is preferably in the general form of a flat plate and presents a front face268aand a rear or back face268b. A first pair of laterally spaced apart threaded projections270preferably project forward and at least substantially orthogonally from the front face268aadjacent one of the ends258. A second pair of laterally spaced apart threaded projections270preferably projects backward and at least substantially orthogonally from the rear face268badjacent the other one of the ends258.

As best shown inFIGS. 11 and 12, each of the slidable support members236b,cpreferably includes a laterally extending body272presenting the aforementioned first and second ends260. The corresponding hooks252b,cpreferably project vertically upward from the respective bodies272when the rack210is in the fully expanded configuration. The hooks252b,care preferably integral with and, more particularly, unitarily formed with, the respective ones of the bodies272, although non-integral formation is permissible. The hooks might, for instance, be adhered, latched, welded, or otherwise attached to the respective body.

Each body272preferably is in the general form of a flat plate and presents a front face and a rear face272b. A first threaded projection274preferably projects forward and at least substantially orthogonally from the front face272a, adjacent the outer or distal one of the ends260.

It is particularly noted that in the assembled rack210, the “local” front face272aof the slidable support member236bfaces forward in a “general” sense (i.e., in the orientation system of the rack210as a whole), while the “local” front face272aof the slidable support member236cfaces rearward in “general” sense. That is, the slidable support members236band236care oriented oppositely of each other in the assembled rack210despite being structurally identical to each other. Thus, the aforementioned collective rotational symmetry of the slidable support members236band236cin the assembled rack210is achieved.

A longitudinally extending slot276is preferably defined through the body272of each slidable support member236b,c. Each slot276presents a pair of ends278. Each slot defines a longitudinal slot length and a vertical (when the rack210is in the fully expanded configuration) slot height. The slot length most preferably approaches a total length of the slidable support member236bor236c(e.g., is at least seventy-five percent (75%), is more preferably at least eighty percent (80%), and is most preferably at least ninety percent (90%) of the total length of the slidable support member236bor236c), as measured between the corresponding ends260.

With respect toFIGS. 13 and 14, each pivotable support member236dand236epreferably includes a laterally extending body280presenting the aforementioned first and second ends264. The corresponding hooks252d,epreferably project vertically upward from the respective bodies280when the rack210is in the fully expanded configuration. The hooks252d,eare preferably integral with and, more particularly, unitarily formed with, the respective ones of the bodies280, although non-integral formation is permissible. The hooks might, for instance, be adhered, latched, welded, or otherwise attached to the respective body.

Each body280preferably is generally in the form of a flat plate and presents a front face280aand a rear face280b. A tab282preferably projects forward and at least substantially orthogonally from the front face280aadjacent the outer one of the ends264. A proximal lip284preferably projects rearward and at least substantially orthogonally to the body280from a bottom edge thereof, adjacent the inner or proximal one of the ends264. The lip284therefore projects horizontally when the rack210is in the fully expanded configuration. Similarly, an intermediate lip288preferably projects rearward and at least substantially orthogonally to the body280from the bottom edge286thereof, at a position spaced between the ends264. The lip288therefore projects horizontally when the rack210is in the fully expanded configuration.

It is particularly noted that in the assembled rack210, the “local” front face280aof the pivotable support member236dfaces forward in a “general” sense (i.e., in the orientation system of the rack210as a whole), while the “local” front face280aof the pivotable support member236efaces rearward in “general” sense. That is, the pivotable support members236dand236eare oriented oppositely of each other in the assembled rack210despite being structurally identical to each other. Thus, the aforementioned collective rotational symmetry of the pivotable support members236dand236ein the assembled rack210is achieved.

First and second notches290and292and are preferably defined through the body280of each pivotable support member236d,e. The notches290and292each define a respective longitudinal notch width and vertical (when the rack210is in the fully expanded configuration) notch depth.

The innermost notch290is in part defined in part by a proximally located rounded portion294of the body280. The rounded portion294is immediately adjacent the proximal or inner one of the ends264and above the proximal lip284. An opening296extends through the rounded portion294.

FIGS. 3-5illustrate the rack210in its fully expanded configuration. Each pair of projections270of the foundational support member236aextends through the slot276of a corresponding one of the slidable support members236band236c. Washers298threaded onto the projections270clamp the slidable support members236band236cto the foundational support member236aand restrict lateral sliding of the slidable support members236band236crelative thereto.

As illustrated, in the fully expanded configuration, the slidable support members236band236care positioned such that the projections270are disposed adjacent the inner ends278of the corresponding slots276, such that the length of the overlapping regions262are minimized to the extent possible given the geometrical constraints of the support members236a-c. That is, within the constraints of the geometry of the support members236a-c, a collective lateral span achieved by the support members236a-cis maximized.

It is noted that the minimum amount of overlap forming the regions262between the foundational support member236aand the slidable support members236band236c, as dictated by the support member geometries, is preferably sufficient to provide adequate structural rigidity for the support members236a-cto support one or more bags248a-cfully loaded with surgical sponges and also to endure bumps, moves, etc. associated with general use in a busy surgical environment.

The projections274of the slidable support members236band236care preferably received in corresponding ones of the openings296formed in the rounded portions294of the corresponding pivotable support member236dor236e, respectively. Nuts300threaded onto the projections274clamp the pivotable support members236dand236eto the corresponding slidable support members236band236c, respectively, and restrict pivoting of the pivotable support members236b,crelative thereto.

As illustrated, in the fully expanded configuration of the rack210, each projection274is disposed at a laterally outermost one of the ends260of the corresponding slidable support member236bor236c. Furthermore, the openings296are disposed at laterally innermost ones of the ends264of the pivotable support members236dand236e. Thus, the lengths of the aforementioned overlapping regions266are minimized (to the extent possible given the geometrical constraints of the support members236b-e). That is, within the constraints of the geometry of the support members236b-e, a collective lateral span achieved by the support members236b-eis maximized.

Thus, it will be apparent that a collective lateral expanded width or span of all of the support members236a-eis maximized when the rack210is in a fully expanded configuration. The expanded width is preferably between about thirty inches (30″) and about seventy inches (70″). More preferably, the expanded width is between about forty inches (40″) and about sixty inches (60″). Most preferably, the expanded width is about fifty-one and twenty-five hundredths inches (51.25″).

Furthermore, it will be apparent that the support members236a-eare collectively (i.e., when viewed as a whole) centered relative to the rod214. More particularly, the bracket238is preferably centrally fixed to the foundational support member236a. The bracket238is therefore laterally centered relative to the support members236a-ein a collective sense both when the bag holder216is in the collapsed configuration and when the bag holder216is in the expanded configuration. Upon securement of the bracket238to the rod214, the support members236a-eare therefore likewise collectively centered relative to the rod214both when the bag holder216is in the collapsed configuration and when the bag holder216is in the expanded configuration.

Still further, the support members236a-ecollectively or cooperatively present radial symmetry about the bracket238and, in turn, the rod214(i.e., at one hundred eighty degree (180°) intervals) both when the bag holder216is in the collapsed configuration and when the bag holder216is in the expanded configuration.

Most preferably, the support members236a-ecollectively extend laterally (or sideways) relative to the rod214when the bag holder is in the expanded configuration. Most preferably, the support members236a-cextend horizontally (or orthogonally relative to the rord214) when the bag holder216is in the expanded configuration. It is also most preferred that each individual one of the support members236a-eextends orthogonally relative to the rod214(or, alternatively stated, horizontally) when the bag holder216is in the expanded configuration.

FIGS. 5 and 6illustrate a process of collapsing the rack210from a fully expanded configuration, through intermediate stages, to a compact, fully contracted configuration best shown inFIGS. 7 and 8. As shown inFIG. 5, for instance, a preferred first step in the collapsing process involves the loosening of the washers298and subsequent laterally inward sliding of the slidable support members236band236crelative to the foundational support member236a. Upon completion of this step, as illustrated inFIG. 6, the hooks252a-care fully aligned with one another.

A preferred second step in the collapsing process involves the loosening of the nuts300and subsequent inward pivoting of the pivotable support members236dand236e(in a vertical plane). As shown inFIG. 7, upon completion of this step, the projections270of the foundational support member236a, along with the washers298threaded thereon, are received in respective ones of the notches290and292. The curvature of the rounded portion294adjacent the notch290provides necessary clearance to enable such pivoting.

Although the above-described method for collapsing the rack210is a preferred method, various other methods may be used, including methods in which the above-described steps are simply performed in a different order.

It is also noted that expansion of the rack210preferably occurs simply through a reversal of the method described above for collapse of the rack210. However, it is again permissible for alternative expansion methods to be used.

In the collapsed configuration of the rack210, the hooks252dand252eextend downward, with the hooks252dbeing laterally offset from the hooks252e. One of the tabs282extends forward (from pivotable support member236d), and another of the tabs282extends rearward (from pivotable support member236e). The tabs provide a gripping point for (preferably manually) initiating a later expansion of the rack210. The lips284and288extend over the tops of adjacent ones of the support members236a-cto restrict inadvertent shifting thereof. More particularly, as shown inFIG. 7, the proximal lip284and intermediate lip288of the pivotable support member236dextend over the sliding support member236band the foundational support member236a. The proximal lip284and the intermediate lip288of the pivotable support member236eextend over the sliding support member236cand the foundational support member236a.

As best shown inFIGS. 7 and 8, in the fully contracted or collapsed configuration of the rack210, the ends260of the slidable support member236balign with the ends264of the adjacent pivotable support member236d. Similarly, the ends260of the other slidable support member236calign with the ends264of the other pivotable support member236e. However, the ends260and264of the support members236band236d, respectively, are laterally offset from the corresponding ends260and264of the support members236cand236e, respectively. Furthermore, each end258of the foundational support member236aaligns with only one pair of the ends260and264. More particularly, the ends258align with the more proximally disposed ones of the ends260and264, in keeping the shorter lateral span of the foundational support member236ain comparison to that of each of the remaining support members236b-e. That is, the support members236band236deach extend past the support member236ain a first direction, while the support members236cand236eeach extend past the support member236ain a second direction.

It is noted that the bodies268,272, and280of the support members236a-eall extend parallel to one another in both the fully expanded and fully contracted configurations of the bag holder216. Still further, the bodies268,272, and280move in or are positioned in parallel planes in any intermediate configurations (i.e., those between fully expanded and fully contracted configurations).

In view of the above, it will be apparent that a collective fore-and-aft depth of the support members236a-eremains constant regardless of the degree of expansion thereof. That is, the depth of the support members236a-ein the fully contracted configuration, the fully expanded configuration, and any intermediate configurations remains constant.

The fore-and-aft depth of the support members236a-eis preferably between about five tenths inches (0.5″) and about three inches (3″). More preferably, the fore-and-aft depth is between about one inch (1″) and about two inches (2″). Most preferably, the fore-and-aft depth is about one and three hundred eighty-five thousandths inches (1.385″).

It is noted that, in some embodiments, certain of the fore-and-aft extending components might be provided with collapsing capability. For instance, the tabs and/or lips in an alternative embodiment might be collapsible for even more compact storage. In such an instance, it is noteworthy that, despite potential variability in the fore-and-aft depth of the support members in a broad sense (i.e., including tabs, lips, etc.), a collective fore-and-aft depth of the bodies268,272, and280is nevertheless constant. In the illustrated embodiment, for instance, the bodies268,272, and280collectively present a constant depth of about six hundred twenty-five thousandths inches (0.625″).

Furthermore, a collective lateral collapsed or contracted width or span of the all of the support members236a-eis minimized when the rack210is in a fully contracted or collapsed configuration. The collapsed width is preferably between about five inches (5″) and about twenty inches (20″). More preferably, the collapsed width is between about seven and five tenths inches (7.5″) and about fifteen and five tenths inches (15.5″). Most preferably, the collapsed width is about eleven and five tenths inches (11.5″).

Preferably, the expanded width is at least two (2) times the collapsed width. More preferably, the expanded width is at least three (3) times the collapsed width. Still more preferably, the expanded width is at least four (4) times the collapsed width. Most preferably, the expanded width is about four and five tenths (4.5) times the collapsed width.

The expandable and collapsible support rack210described above provides numerous advantages. Among other things, for instance, the rack210in its fully expanded configuration enables an advantageously high number of sponge bags248a-eto be hung on a single side, fully visible from any one of numerous single vantage points. In turn, an unobstructed count of numerous used surgical sponges may be obtained from a single vantage point, eliminating unnecessary movement by the “counter” of the sponges to shift overlapping bags, view the rack210from another side, etc.

The rack210also requires a very small floor footprint in contrast to its significant display capacity, while also being collapsible into a very small overall envelope to take minimal space when not in use.

Still further, partial expansion or contraction of the rack210is feasible, enabling surgical practitioners to determine the most appropriate balance between space usage and display capacity. For instance, in a crowded operating theater associated with a surgery requiring only a moderate number of sponges, the rack210might be opened only to the configuration shown inFIG. 6, in which three (3) bags can be hung on three (3) support members.

It is again noted that, although five (5) support members236a-eare illustrated, it is permissible according to some aspects of the present invention for more or fewer support members to be provided. Furthermore, the support members might be alternatively arranged (e.g., placed in a different order) or, according to some aspects of the present invention, include proportionally more or fewer slidable members or pivotable members. Exclusive use of pivoting members or of sliding members also falls within the scope of some aspects of the present invention.

Still further, variations in the configurations of individual support members may occur. For instance, certain aspects of the present invention encompass a foundational support member that is configured so that each half thereof is angled relative to or offset from (e.g., neither parallel to nor aligned with) the other half. The halves might also vary in lateral extent or in general configuration (e.g., be non-symmetrical relative to each other). It is noted that such alternative configurations would likewise result in a bag holder that is as a whole comprised of non-symmetrical, non-identical, angled, and/or offset lateral halves or portions.

In another embodiment, the bag holder might have asymmetrical sides at least with respect to the manner in which the support members are intercoupled. For instance, to maintain balance, the sides might project equidistantly relative to the foundational support member and also have similar weight (although some variance is acceptable according to some aspects of the present invention), yet be operably coupled to one another differently on one side than on the other. That is, pivotable support members might be provided on one side and slidable support members on the other, varying combinations of shiftability might be provided on each side, etc.

Design 2: Slidable J-Handle Support Members

FIGS. 15-19illustrate a second preferred surgical sponge rack310. It is initially noted that, with certain exceptions to be discussed in detail below, many of the elements of rack310of the second embodiment are the same as or very similar to those described in detail above in relation to the rack210of the first embodiment. Therefore, for the sake of brevity and clarity, redundant descriptions and numbering will be generally avoided here. Unless otherwise specified, the detailed descriptions of the elements presented above with respect to the first embodiment should therefore be understood to apply at least generally to the second embodiment, as well.

Similarly to the rack210, the rack310of the second preferred embodiment preferably includes a base312, a mounting rod314, a bag holder316, and a top318. The bag holder316includes a frame320and plurality of support members322a-fsecured relative to the frame320. Bags324a-fhang from the support members322a-f. The bag holder316also preferably includes a bracket326and a clamp328.

The bag holder316is preferably formed of metal, although other materials fall within the scope of the present invention.

As illustrated, the frame320preferably is in the form of a rounded rectangle (i.e., a rectangle with rounded corners) including a top and bottom320aand320b, respectively, and sides320cand320d. The frame320is fixed to the bracket326, which in turn is fixed to the clamp328. The clamp328is secured relative to the rod314to support the support members322a-fon the rod314.

The bracket326preferably extends in a forward direction such that the support members322a-fare disposed on a front side of the rack310(i.e., on one side of the rod314) in a general sense.

The support members322a-fpreferably include front and rear foundational support members322aand322b, respectively; front and rear intermediate support members322cand322d, respectively; and front and rear distal or outer support members322eand322f, respectively. (As noted above, all of the support members322a-fare disposed on a front side of the rack310in a general sense. “Front” and “rear” are used here in a more local sense to describe the positions of the support members322a-frelative to each other. That is, the support members322a,c,eare disposed forward of the support members322b,d,f; but all support members322a-fare forward of the rod314.)

The foundational support members322aand322bare preferably integrally formed with one another and, more particularly, are preferably unitarily formed. As will be discussed in greater detail below, the intermediate support members322cand322dare preferably laterally slidable relative to respective ones of the foundational support members322aand322b, while the outer support members322eand322fare laterally slidable relative to respective ones of the intermediate support members322cand322d.

Preferably, each support member322a-fincludes a pair of pegs or hooks330a-fprojecting upwardly therefrom when the support members322a-f(or, alternatively stated, the rack310or the bag holder316) are in an expanded configuration. Each hook330a-fpreferably includes a respective base332a-fand a head334a-f, with each head334a-frestricting slippage of a corresponding mounted bag324a-foff of the corresponding support member322a-f.

In the illustrated embodiment, the bases332a-fare preferably in the form of cylindrical posts. The heads334a-fare preferably in the form of radially enlarged cylinders or disks. A variety of hook shapes fall within the scope of the present invention, however.

The support members322a-fare each preferably generally J-shaped, with a straight, longitudinally (i.e., laterally) extending arm338a-fand a curved handle340a-f. Each arm338a-fpresents proximal and distal (i.e., inner and outer) ends342a-fand344a-f, respectively. Each handle340a-fextends from the corresponding one of the outer ends344a-f.

The arms338a-fand handles340a-fof each of the support members322a-fare preferably structural identical to one another, although variations are permissible within the scope of the present invention.

The arm338aof the front foundational support member322ais disposed forward of the arm338bof the rear foundational support member322b. Furthermore, a portion of the front arm338alaterally overlaps (but preferably is not in direct contact with) a portion of the rear arm338b, such that an overlapping region346is cooperatively defined by the arms338aand338b.

The handle340aof the front foundational support member322acurves or extends backward. The handle340bof the rear foundational support member322bcurves or extends forward. Most preferably, the extension of the handles340aand340bis such that an end348of the handle340aof the front foundational support member322ais at least in part laterally aligned with the arm338bof the rear foundational support member330b. Similarly, an end350the handle340bof the rear foundational support member322bis most preferably at least in part laterally aligned with the arm338aof the front foundational support member322a. Disalignment is permissible without departing from the scope of the present invention, however.

Preferably, the front and rear foundational support members322aand322bare identical to each other. That is, they vary only in orientation (and not in structure). Numerous variations fall within the scope of the present invention, however.

In keeping with the above-described preferred alignment of handle ends348and350with arms348band248a, respectively, it is noted that the overlapping portions of the front and rear foundational support members322aand322bthat define the aforementioned overlapping region346most preferably do not include the entirety of the respective arms348aand348b. Furthermore, in view of their preferred structural conformity, it will be apparent that the hooks330aof the front foundational support member322aare laterally offset from the hooks330bof the rear foundational support member330bin a preferred embodiment of the rack210. As will be discussed in greater detail below, the offset nature of the hooks330aand330bensures that bags324aand324bhanging therefrom will not overlap in their entirety, although partial overlap occurs the illustrated preferred embodiment.

In contrast to the foundational support members322a,b, each intermediate support member322c,dand outer support member322e,fpreferably includes a sleeve352c-fextending forward or rearward from the corresponding arm338c-f.

More particularly, the sleeves352c-fand352eof the front intermediate and outer support members322cand322e, respectively, preferably include a respective bottom portion354c,eextending rearwardly from a bottom surface356c,eof each respective arm338c,e. Furthermore, a pair of side portions358c,eextends upwardly from the respective bottom surface356c,e. Each pair of side portions358c,edefines a respective channel360c,etherebetween.

The side portions358cof the sleeve352cof the front intermediate support member322cpreferably extend around the arm338aof the front foundational support member322a. Alternatively stated, the arm338aof the front foundational support member322apreferably extends through the channel360c. The side portions358eof the sleeve352eof the front outer support member322epreferably extend around the arm338cof the front intermediate support member. Alternatively stated, the arm338cof the front intermediate support member322cpreferably extends through the channel360e.

In contrast, the sleeves352dand352fof the rear intermediate and outer support members322dand322f, respectively, preferably include a bottom portion354d,fextending forwardly from a bottom surface356d,fof each respective arm338d,f. Furthermore, a pair of side portions358d,fpreferably extends upwardly from the respective bottom surface356d,f. Each pair of side portions358d,fdefines a respective channel360d,ftherebetween.

The side portions358dof the sleeve252dof the rear intermediate support member322dpreferably extend around the arm338bof the front foundational support member322b. Alternatively stated, the arm338bof the rear foundational support member322bpreferably extends through the channel360d. The side portions358fof the sleeve252fof the rear outer support member322fpreferably extend around the arm338dof the rear intermediate support member322d. Alternatively stated, the arm338dof the rear intermediate support member322dpreferably extends through the channel360f.

Thus, the front outer support member322eis longitudinally slidable along the arm338cof the front intermediate support member322c, which in turn is longitudinally slidable along the arm338aof the front foundational support member322a. Similarly, the rear outer support member322fis longitudinally slidable along the arm338dof the rear intermediate support member322d, which in turn is longitudinally slidable along the arm338bof the rear foundational support member322b.

In the illustrated embodiment, the channels360c-fare each generally hexagonally prismatic in form, although other shapes (e.g., circularly cylindrical, rectangularly prismatic, etc.) are permissible. Most preferably, pairs of channels and arms are shaped to correspond to one another to facilitate efficient sliding of the arms within the respective channels.

As will be discussed in greater detail below, the slidability of the various support members322a-fof the rack310of the second preferred embodiment enables expansion and contraction of the rack310in a manner similar to the rack210of the first preferred embodiment and confers similar advantages.

Each of the foundational support members322aand322band intermediate support members322cand322dpreferably includes a stopper peg362a-dextending forward or rearward therefrom. More particularly, the front foundational and intermediate support members322aand322cinclude respective pegs362aand362cextending rearward therefrom. The rear foundational and intermediate support members322band322dinclude respective pegs362band362dextending forward therefrom. The pegs362a-dpreferably extend from respective ones of the outer ends344a-dof the arms338a-d, so as to be disposed at the juncture of each respective set of arms338a-dand handles340a-f.

Presence of additional stopper pegs is permissible without departing from the scope of the present invention, as is alternative positioning of the stopper pegs. Most preferably, however, any stopper pegs that are provided will serve functional roles at least similar to those described below with regard to the illustrated pegs362a-d.

As shown inFIGS. 15 and 16, in a fully expanded state, the intermediate support members322cand322dare positioned laterally outward relative to the foundational support members322aand322b. Similarly, the outer support members322eand322fand are disposed laterally outward of the intermediate support members322cand322d. The extent to which the support members322a-fand are laterally offset from one another is dictated by the stopper pegs362a-dand the sleeves352c-f.

More particularly, further outward shifting of the front outer support member322eis prevented by engagement of an outer face of its sleeve352ewith the peg362cof the front intermediate support member322c. Further outward shifting of the front intermediate support member322cis prevented by engagement of an outer face of its sleeve362cwith the peg362aof the front foundational support member322a.

Likewise, further outward shifting of the rear outer support member322fis prevented by engagement of an outer face of its sleeve352fwith the peg362dof the rear intermediate support member322d. Further outward shifting of the rear intermediate support member322dis prevented by engagement of an outer face of its sleeve362dwith the peg362bof the rear foundational support member322b.

As illustrated, a collective lateral expanded width or span of the all of the support members322a-fis at least substantially maximized when the rack310is in a fully expanded configuration. The expanded width is preferably between about thirty inches (30″) and about seventy inches (70″). More preferably, the expanded width is between about forty inches (40″) and about sixty inches (60″) inches. Most preferably, the expanded width is about forty-nine and ten hundredths inches (49.10″).

Furthermore, it will be apparent that the support members322a-fare collectively (i.e., when viewed as a whole) centered relative to the rod314. Still further, the support members322a-fcollectively or cooperatively present radial symmetry about the rod314(i.e., at one hundred eighty degree (180°) intervals).

Preferably, interaction of certain ones of the sleeves352c-fwith certain ones of the hooks330a-fprovides further control of the sliding or shifting process of the support members322c-f. Such control might restrict, among other things, rotation of the support members relative to one another along a longitudinal or lateral axis. For instance, during shifting of the front outer support member322erelative to the front intermediate support member322c, the sleeve352epreferably passes by the outer one of the hooks330c. Alternatively stated, the base332cof the hook330cpasses through a gap364edefined between the ends of the side portions358eof the sleeve352e, above the channel360e. During shifting of the front intermediate support member322crelative to the front foundational support member322a, the sleeve352cpreferably passes by the outer one of the hooks330a. Alternatively stated, the base332aof the hook330apasses through a gap364cdefined between the ends of the side portions358cof the sleeve358c, above the channel360c.

During shifting of the rear outer support member322frelative to the rear intermediate support member322d, the sleeve352fpreferably passes by the outer one of the hooks330d. Alternatively stated, the base332dof the hook330dpasses through a gap364fdefined between the ends of the side portions358fof the sleeve358f, above the channel360fDuring shifting of the rear intermediate support member322drelative to the rear foundational support member322b, the sleeve352dpreferably passes by the outer one of the hooks330b. Alternatively stated, the base332bof the hook330bpasses through a gap364ddefined between the ends of the side portions358dof the sleeve358d, above the channel360d.

It is noted that is permissible according to some aspects of the present invention for additional projections to also be provided to further guide the relative motion of the support members. For instance, a continuous rib and/or one or more discrete projections might be provided.

Furthermore, rotational restriction of the support members322c-fabout the respective longitudinal axes of the arms338c-fthereof may be provided simply by the geometries of the arms338c-frelative to the sleeves352c-fand the channels360c-f. For instance, whereas circularly cylindrical arms in correspondingly shaped channels would rotate at least substantially freely within their corresponding sleeves (absent other constraints), hexagonally prismatic arms338c-fsuch as those illustrated are restricted from rotating in the channels360c-fat least in part due to the fitted nature of the sleeves352c-f, the congruent shape of the channels360c-f, and the presence of flat sides and corners associated with the hexagonal cross-sectional shape.

As illustrated inFIG. 15, three (3) bags324a,c,e, each including ten (10) pockets366a,c,e, are preferably substantially visible from a front vantage point (when hanging from respective ones of the front support members322a,c,e). Although the bags366aand366cand the bags366cand366eoverlap slightly, any sponges that might be contained in the pockets366a,c,ewould remain visible and easily accounted for. An additional two (2) bags (not illustrated for purposes of clarity), each also including ten (10) pockets, preferably hang from the rear support members322d,fin such a manner that the pockets thereof face forward. These additional bags may also overlap slightly with one another and with bag366ain the manner described above; however, any sponges contained therein should likewise remain substantially visible and easily accounted for. It is noted that “substantially” as used in the present sense should be understood to mean simply that any overlap that occurs between adjacent bags is small enough that any sponges held in said bags are readily visible for easy and unambiguous counting.

Similarly, as illustrated inFIG. 15, three (3) bags324b,d,f, each including ten (10) pockets366b,d,f, are preferably substantially visible from a rear vantage point (when hanging from respective ones of the rear support members322b,d,f). Although the bags366band366dand the bags366dand366foverlap slightly, any sponges that might be contained in the pockets366b,d,fwould remain visible and easily accounted for. An additional two (2) bags (not illustrated for purposes of clarity), each also including ten (10) pockets, preferably hang from the front support members322c,ein such a manner that the pockets thereof face rearward. These additional bags may also overlap slightly with one another and with bag366bin the manner described above; however, any sponges contained therein should likewise remain substantially visible and easily accounted for. It is noted that “substantially” as used in the present sense should be understood to mean simply that any overlap that occurs between adjacent bags is small enough that any sponges held in said bags are readily visible for easy and unambiguous counting.

Thus, as many as fifty (50) sponges could be visually accounted for from a single vantage point, with as many as one hundred (100) sponges visible in total (from two (2) vantage points) without any shifting of bags being necessary.

As shown inFIG. 16, in a preferred method of collapsing the rack310, the intermediate support members322cand322dare first slid laterally inwardly along respective ones of the arms338aand338bof the foundational support members322aand322b. The outer ones of hooks330aand330bpass through corresponding gaps364cand364din sleeves352cand352d. Engagement of pegs362cand362dwith respective ones of the sleeves352eand352fforces the outer support members322eand322fto also shift inward along with the intermediate support members322cand322d. Inward shifting of the intermediate support members322cand322dis completed upon engagement of the pegs362cand362dwith respective sides320cand320dof the frame320(see, for instance,FIG. 17).

As shown inFIG. 17, the outer support members322eand322fare then preferably slid laterally inwardly along respective ones of the arms338cand338dof the intermediate support members322cand322d. The outer ones of hooks330cand330dpass through corresponding gaps364eand364fin sleeves352eand352f. Inward shifting of the outer support members322eand322fis completed upon engagement of the sleeves352eand352fthereof with corresponding ones of the sleeves352cand352dof the intermediate support members322cand352d. The fully closed or compact configuration is illustrated inFIGS. 18 and 19.

Although the above-described method for collapsing the rack310is a preferred method, various other methods may be used, including but not limited to methods in which the above-described steps are simply performed in a different order.

It is also noted that expansion of the rack310preferably occurs simply through a reversal of the method described above for collapse of the rack310. However, it is again permissible for alternative expansion methods to be used.

A collective lateral collapsed or contracted width or span of all of the support members322a-fis preferably minimized when the rack310is in a fully contracted or collapsed configuration. The collapsed width is preferably between about five inches (5″) and about twenty-five inches (25″). More preferably, the collapsed width is between about ten inches (10″) and about twenty inches (20″). Most preferably, the collapsed width is about fifteen and one tenth inches (15.1″).

Preferably, the expanded width is at least two (2) times the collapsed width. More preferably, the expanded width is at least three (3) times the collapsed width. Most preferably, the expanded width is about three and twenty-five hundredths (3.25) times the collapsed width.

It is also noted that the arms338a-fof the support members322a-fall extend parallel to one another in both the fully expanded and fully contracted configurations of the bag holder316, as well as during any movements that occur during expansionary or contractionary processes.

In view of the above, it will be apparent that a collective fore-and-aft depth of the support members338a-fremains constant regardless of the degree of expansion thereof. That is, the depth of the support members338a-fin the fully contracted configuration, the fully expanded configuration, and any intermediate configurations remains constant.

The fore-and-aft depth of the support members338a-fis preferably between about two inches (2″) and about six inches (6″). More preferably, the fore-and-aft depth is between about three inches (3″) and about five inches (5″). Most preferably, the fore-and-aft depth is about four and one tenth inches (4.1″).

It is further noted that the collective vertical height of the support members338a-f(including the hooks330a-f) also remains constant regardless of the degree of expansion thereof. That is, the vertical height of the support members338a-fin the fully contracted configuration, the fully expanded configuration, and any intermediate configurations remains constant. Most preferably, the height is between about one inch (1″) and about four inches (4″). More preferably, the height is between about two inches (2″) inches and about three inches (3″). Most preferably, the height is about two and four tenths inches (2.4″).

It is noted that the collective vertical height of the arms338a-fand handles340a-fof the support members338a-f(i.e., excluding the hooks330a-f) is likewise preferably constant regardless of the degree of expansion thereof. That is, the vertical height of the arms338a-fand handles340a-fof the support members338a-fin the fully contracted configuration, the fully expanded configuration, and any intermediate configurations remains constant. Most preferably, the height is between about one and five tenths inches (1.5″) and about three and five tenths inches (3.5″). More preferably, the height is between about two and five tenths inches (2.5″) and about three and five tenths inches (3.5″). Most preferably, the height is about one and eighty-five hundredths inches (1.85″).

Similarly to the rack210of the first preferred embodiment, the expandable and collapsible rack310described above provides numerous advantages. Among other things, for instance, the rack310in its fully expanded configuration enables an advantageously high number of sponge bags to be hung on a single side, fully visible from any one of numerous single vantage point. In turn, an unobstructed count of numerous used surgical sponges may be obtained from a single vantage point, eliminating unnecessary movement by the “counter” to shift overlapping bags, view the rack310from another side, etc. A still higher count can be obtained through use of only two (2) vantages points, such as a centered front vantage point and a centered rear vantage point, or, perhaps more conveniently, a pair of very closely spaced vantage points offset only slightly from the side of the rack310so as to be slightly forward and slightly aft thereof.

The rack310also requires a very small floor footprint in contrast to its significant display capacity, while also being collapsible into a very small overall envelope to take minimal space when not in use.

Still further, partial expansion or contraction of the rack310is feasible, enabling surgical practitioners to determine the most appropriate balance between space usage and display capacity. For instance, in a crowded operating theater associated with a surgery requiring only a moderate number of sponges, the rack310might be opened only to the configuration shown inFIG. 17, in which four (4) bags can be hung on four (4) support members in a two (2)-on-each-side configuration.

It is noted that, although six (6) support members322a-fare illustrated, it is permissible according to some aspects of the present invention for more or fewer support members to be provided. Furthermore, the support members might be alternatively arranged (e.g., placed in a different order) or, according to some aspects of the present invention, include alternatively shiftable (e.g., pivotable) members.

Design 3: Slidable Flat Plate Support Members

FIGS. 20-29illustrate a third preferred surgical sponge rack410. It is initially noted that, with certain exceptions to be discussed in detail below, many of the elements of the rack410of the third embodiment are the same as or very similar to those described in detail above in relation to the rack210of the first embodiment and/or the rack310of the second embodiment. Therefore, for the sake of brevity and clarity, redundant descriptions and numbering will be generally avoided here. Unless otherwise specified, the detailed descriptions of the elements presented above with respect to the first and/or second embodiments should therefore be understood to apply at least generally to the third embodiment, as well.

Similarly to the racks210and310, the rack410of the second preferred embodiment preferably includes a base412, a mounting rod414extending at least substantially vertically from the base412, a bag holder416, and a top418.

Similarly to the bag holders216and316, and as will be discussed in greater detail below, the bag holder416is shiftable between fully contracted and fully expanded configurations corresponding to so-called fully contracted and fully expanded configurations of the rack410as a whole.

The bag holder416preferably includes a plurality of support members420,422, and424. The bag holder416further preferably includes a bracket426supporting the support members420,422, and424, and a clamp428supporting the bracket426on the rod414. The bracket426preferably extends forward from the rod414such that the support members420,422, and424are disposed on a front side of the rack410.

In a preferred embodiment, a plurality of bags430a-e, each including respective pluralities of pockets432a-e, hang from respective ones of the support members420,422, and424. Most preferably, each of the bags430a-ehangs from a front side of the rack410such that the pockets432a-eare all visible from a single position, such as a vantage point in front of the rack410.

It is noted that, in accordance with some aspects of the present invention, the bags might alternatively be hung to optimize or enable viewing from other vantage points, including but not limited to a vantage points on the side or to the rear of the rack. In the latter case, for instance, the bags might be hung on the back side of the rack. Still further, the bags might be hung in such a manner as to optimize or enable the use of multiple vantage points. For instance, a portion of the bags might be hung from a front side of the rack to facilitate viewing from a front vantage point, while another portion of the bags might be hung from a rear side of the rack to facilitate viewing from a rear vantage point.

The support members420,422, and424most preferably include a foundational support member420, a pair of slidable intermediate support members422, and a pair of slidable outer support members424. It is noted that, in contrast, the outer support members236d,eof the rack210of the first preferred embodiment were pivotable rather than slidable.

The foundational support member420is preferably centered on the rod414so as to extend laterally therefrom, equidistantly in two (2) opposing directions. The foundational support member420as a whole also preferably possesses radial (i.e. rotational) symmetry about a vertical axis defined by the rod414.

More particularly, as best shown inFIGS. 24 and 25, the foundational support member420preferably includes a body420aincluding opposite longitudinal ends420band opposite top and bottom edges420cand420d. The body420ais preferably in the form of a flat plate presenting front and rear faces420eand420f.

A respective hook420gis disposed inward of and adjacent each end420b, projecting upwardly from the top edge420cof the body420a, such that the foundational support member420includes two (2) hooks420g.

A first pair of laterally spaced apart threaded projections420hextends rearward from the rear face420fadjacent a first one of the ends420b. A second pair of laterally spaced apart threaded projections420hextends forward from the front face420eadjacent the other of the ends420b. An inner one of the projections420hof each pair preferably aligns vertically with a corresponding one of the hooks420g. That is, each hook420gis preferably disposed directly above a corresponding one of the projections420h.

As will be discussed in greater detail below, the projections420hpreferably extend from a lower portion of the body420a(i.e., nearer the bottom edge420dthan the top edge420e).

As best shown inFIGS. 26 and 27, the intermediate support members422are preferably identical to each other and mirror each other about the aforementioned axis. Certain variations fall within the scope of some aspects of the present invention, however.

Each intermediate support member422preferably includes a body422a. The body422ais preferably in the form of a flat plate presenting front and rear faces422band422c. The body422apreferably includes opposite proximal (inner) and distal (outer) longitudinal ends422dand422e. The body422afurther preferably includes and opposite top and bottom edges422fand422g.

The proximal ends422deach preferably overlap or are disposed inward of the corresponding end420bof the foundational support member420when the rack410is the expanded configuration. Respective inner overlapping regions434(seeFIG. 21) are thus defined by the foundational support member420and each of the two (2) intermediate support members422when in intermediate and expanded configurations. (As will be apparent to those of ordinary skill in the art, the size of such overlapping regions434varies depending on the degree of expansion.)

As shown inFIG. 22, each of the intermediate support members422preferably presents a first, proximal hook422hdisposed outward of and adjacent the inner end422dso as to be outwardly adjacent the corresponding hook420gof the foundational support member420when the rack410is in the expanded configuration. Each of the intermediate slidable support members422further preferably presents paired second and third distal hooks422iand422jdisposed inward of and adjacent the outer end422e.

Each intermediate support member422further preferably includes a pair of laterally spaced apart threaded projections422kextending forward from the front face422badjacent the outer end422e. The projections422kpreferably extend from an upper portion of the body422a(i.e., nearer the top edge422fthan the bottom edge422g). Each projection422kpreferably aligns vertically with a corresponding one of the distal hooks422iand422jThat is, each hook422iand422jis preferably disposed directly above a corresponding one of the projections422k.

Still further, a longitudinally extending slot4221is preferably defined through the body422aof each intermediate support member422. Each slot4221presents a pair of proximal and distal ends422mand422n, respectively. Each slot4221defines a longitudinal slot length and a vertical slot height. The slot length most preferably approaches a total length of the intermediate support member422. Each slot4221is preferably disposed in a lower portion of the body422a(i.e., nearer the bottom edge422gthan the top edge422f).

As best shown inFIGS. 28 and 29, the outer support members424are preferably identical to each other and mirror each other about the aforementioned axis. Certain variations fall within the scope of some aspects of the present invention, however.

Each outer support member424preferably includes a body424a. The body424ais preferably in the form of a flat plate presenting front and rear faces424band424c. The body424apreferably includes opposite proximal (inner) and distal (outer) longitudinal ends424dand424eand opposite top and bottom edges424fand424g.

The proximal ends424deach preferably overlap or are disposed inward of the corresponding distal ends422eof the corresponding intermediate support member422when the rack410is the expanded configuration. An outer overlapping region436(seeFIG. 21) is thus defined between each corresponding pair of intermediate and outer support members422and424, respectively, when in expanded and intermediate configurations. (As will be apparent to those of ordinary skill in the art, the size of such overlapping regions436varies depending on the degree of expansion.)

Each of the outer support members424preferably presents a single, distal hook424hprojecting upwardly from the top edge424fand disposed inward of and adjacent the outer end424e.

A longitudinally extending slot424iis preferably defined through the body424aof each outer support member424. Each slot424ipresents a pair of proximal and distal ends424jand424k, respectively. Each slot defines a longitudinal slot length and a vertical slot height. The slot length most preferably approaches a total length of the outer support member424. Each slot424iis preferably disposed in a central portion of the body424a(i.e., at least substantially equidistant from the top and bottom edges424fand424g, respectively).

A tab4241preferably projects forward and at least substantially orthogonally relative to the corresponding front face424bat each outer end424e.

Preferably, the bodies420aand422aof the foundational and intermediate support members420and422, respectively, are each at least substantially identically sized and shaped except as noted above. That is, a height of the foundational support member420defined between the top and bottom edges420cand420dthereof is preferably equal to similarly defined heights of the intermediate support members422. Likewise, widths defined between ends420band between end422dand422e, respectively, are preferably equal.

In contrast, a similarly defined height of each outer support member424is most preferably about half that of the foundational support member420and of the intermediate support members422. A similarly defined length of each outer support member424is preferably slightly less than (for instance, about ninety (90) percent) that of the foundational support member420and of the intermediate support members422.

FIGS. 20 and 21illustrate the rack410in its fully expanded configuration. The projections422kof each intermediate support member422extend through the corresponding slot424iin the corresponding outer support member424and thereby support the corresponding outer support member424. An inner one of each pair of projections422kengages the inner end424jof the corresponding slot424ito restrict further outward motion of the outer support member424. Dome nuts438are secured to the projections422kto restrict fore/aft shifting of the outer overlapped regions436, as well as inadvertent relative lateral shifting (e.g., inadvertent collapse of the bag holder416).

Similarly, the projections420hof the foundational support member420extend through corresponding ones of the slots4221in the corresponding intermediate support members422to support the corresponding intermediate support members422. An inner one of each pair of projections420hengages the inner end422mof the corresponding slot4221to restrict further outward motion of the intermediate support member422. Dome nuts440are secured to the projections420hto restrict fore/aft shifting of the overlapped regions434, as well as inadvertent relative lateral shifting (e.g., inadvertent collapse of the bag holder416).

It is noted that, in the fully expanded configuration, the intermediate and outer support members422and424are positioned such that the lengths of the inner and outer overlapping regions346and436are minimized to the extent possible (i.e., given the geometrical constraints of the support members420,422, and424). That is, within the constraints of the geometry of the support members420,422, and424, a collective lateral width or span achieved by the support members420,422, and424is maximized.

FIGS. 22 and 23illustrates a preferred process of collapsing the rack410from the fully expanded configuration ofFIG. 21, through intermediate stages such as that shown inFIG. 22, to a compact, fully contracted configuration best shownFIG. 23. First, if necessary, some or all of the dome nuts438and440are loosened. Most preferably, the nuts438and440are set so as to sufficiently restrict unintentional lateral shifting but facilitate intentional expansion or collapse without additional adjustment, making such a step unnecessary. However, adjustments may be made before, during, and/or after any of the steps in a collapsing or expanding process without departing from the scope of some aspects of the present invention.

Next, laterally inward shifting of the outer support members424relative to the (presently preferably stationary) intermediate support members422is initiated via pressure on the tabs4241. In this example methodology, the application of force and the biasing of the dome nuts438and430is such that the outer support members424shift fully inwardly relative to the intermediate support members422without any laterally inward shifting of the intermediate support members422occurring. However, it is permissible according to some aspects of the present invention for shifting to occur simultaneously, either proportionally (e.g., at an equal rate) or non-proportionally (e.g., more slowly for the intermediate support members422). Also, it is permissible for shifting to occur symmetrically or asymmetrically, or variably, as dictated by the forces applied, the biasing of the dome nuts438and440(so as to facilitate a preferred degree of friction between paired members422and424), etc.

As shown inFIG. 22, upon completion of this step (and assuming shifting of the only the outer support members424has occurred), the outer of the projections422k(hidden from view underneath corresponding dome nuts438) engage corresponding ones of the outer slot ends424k, two (2) sets of hooks422jand424hoverlie one another, and the bottom edge424gof each outer support member424is disposed adjacent the corresponding slot4221of the corresponding intermediate support member422. Furthermore, the outer ends422eand424ealign with one another, as do the top edges422fand424f.

In a preferred methodology, simultaneous and proportional laterally inward shifting of the intermediate support members422and the outer support members424relative to the stationary foundational support member420is initiated next via continued pressure on the tabs4241and consequent transfer of force from each outer support member424to the corresponding intermediate support member422via the outer one of the respective projections422k. This step ends with the rack410in a fully collapsed configuration, as shown inFIG. 23, with the support members420,422, and424forming a compact stack consisting of a foremost one of the outer support members424, overlying a foremost one of the intermediate support members422, overlying the foundational support member420, overlying a rearmost one of the intermediate support members422, overlying a rearmost one of the outer support members424.

More particularly, upon completion of this step, the outer of the projections422k(topped by corresponding dome nuts438) still engage corresponding ones of the outer slot ends424k. Furthermore, the outer of the projections420h(topped by corresponding dome nuts440) additionally engage corresponding ones of the outer slot ends422n. Two (2) sets of hooks422jand424hstill overlie one another; and two (2) additional sets of overlying hooks420g,422i, and422hare additionally formed (the hooks422iand422hin each overlying set of course being from different ones of the intermediate support members422). As before, the bottom edge424gof each outer support member424is disposed adjacent and above the corresponding slot4221of the corresponding intermediate support member422. The bottom edges420dand422gof the foundational and intermediate support members420and422align with one another, as do all of the top edges420c,422f, and424fof the foundational, intermediate, and outer support members420,422, and424.

Still further, the outer ends424eand422eof the foremost outer and intermediate support members424and422, respectively, align with corresponding ends420bof the foundational support member and with the inner end422dof the rearmost of the intermediate support members422. The inner end424dof the rearmost outer support member424is disposed inward of the aforementioned aligned ends424e,422e,420b, and422d. Conversely, the outer ends424eand422eof the rearmost outer and intermediate support members424and422, respectively, align with the other end420bof the foundational support member and with the inner end422dof the foremost of the intermediate support members424. The inner end424dof the foremost outer support member424is disposed inward of the aforementioned aligned ends424e,422e,420b, and422d.

It is noted that the bodies420a,422a, and424aall extend parallel to one another in the fully expanded, fully contracted, and any intermediate configurations of the bag holder416. This is in contrast to the rack210of the first preferred embodiment, in which the pivoting members236dand236eare not parallel with the remaining members236a,236b, and236dduring some stages of collapse.

In view of the above, it will be apparent that a collective fore-and-aft depth of the support members420,422, and424remains constant regardless of the degree of expansion thereof. That is, the depth of the support members420,422, and424in the fully contracted configuration, the fully expanded configuration, and any intermediate configurations remains constant.

The collective fore-and-aft depth of the support members420,422, and424, including the tabs4241, is preferably between about five tenths inches (0.5″) and about three inches (3″). More preferably, the fore-and-aft depth is between about one inch (1″) and about two inches (2″). Most preferably, the fore-and-aft depth is about one and three hundred eighty-five thousandths inches (1.385″). The bodies420a,422a, and424aof the support members420,422, and424collectively present a constant depth of about five eighths inches (0.625″).

Similarly to the rack310of the second preferred embodiment but in contrast to the rack210of the first preferred embodiment, a collective vertical height (i.e., along the direction of the rod axis) of the support members420,422, and424remains constant regardless of the degree of expansion thereof. That is, the collective height of the support members420,422, and424in the fully contracted configuration, the fully expanded configuration, and any intermediate configurations remains constant.

Most preferably, the collective height of the support members420,422, and424, excluding the hooks420g,422h,422i,422j, and424h, is between about one half inch (0.5″) and about three inches (3″). More preferably, the height is between about one inch (1″) and about two inches (2″). Most preferably, the height is about one and three eighths inches (1.375″). In greater detail still, each of the bodies420aand422apreferably has a height of about one and three eighths inches (1.375″). Each of the bodies424apreferably has a height of about three quarters inches (0.75″).

Still further, a collective lateral collapsed or contracted width or span of all of the support members420,422, and424is minimized when the rack410is in a fully contracted or collapsed configuration.

The collective collapsed width of all of the support members420,422, and424, including the tabs4241, is preferably between about five inches (5″) and about twenty inches (20″). More preferably, the collapsed width is between about seven and five tenths inches (7.5″) and about fifteen and five tenths inches (15.5″). Most preferably, the collapsed width is about eleven and five tenths inches (11.5″).

Preferably, the expanded width is at least two (2) times the collapsed width. More preferably, the expanded width is at least three (3) times the collapsed width. Still more preferably, the expanded width is at least four (4) times the collapsed width. Most preferably, the expanded width is about four and five tenths (4.5) times the collapsed width.

The collective expanded width of all of the support members420,422, and424, including the tabs4241, is preferably between about twenty-five inches (25″) and about sixty-five inches (65″). More preferably, the expanded width is between about thirty-five inches (35″) and about fifty-five inches (55″). Most preferably, the expanded width is about forty-five and three quarters inches (45.75″).

Preferably, each of the bodies420aand422ahas a width of about eleven inches (11″). Each of the bodies424apreferably has a width of about ten and one eighth inches (10.125″).

Although the above-described method for collapsing the rack410is a preferred method, various other methods may be used, including methods in which the above-described steps are simply performed in a different order or in whole or partially simultaneously. For instance, as noted above, the initial shifting of the outer support members might be accompanied by at least some degree of shifting of the intermediate support members, one of the outer support members might move inward more rapidly than the other, etc. Application of necessary forces may also be to other components of the rack410, not just to the tabs4241as described above, also resulting in various different sequences of movement.

Expansion of the rack410is preferably initiated with outward shifting of each of the outer support members424relative to the corresponding ones of the intermediate support members422, which preferably remain stationary, as a result of force being applied to the tabs4241.

When the inner end424jof the slot424iof each outer support member242engages the corresponding inner one of the projections422k(beneath a corresponding dome nut438) of the corresponding intermediate support member242, continued force applied to the tabs4241results in transfer of force from each outer support member424to the corresponding intermediate support members422via the projections422k. This results in outward shifting of both the outer support members424and the intermediate support members422, with shifting of corresponding ones of the intermediate and outer support members422and424preferably occurring simultaneously and proportionally.

Outward shifting is complete when the inner ones of the projections420h(beneath corresponding dome nuts440) of the foundational support member420engage corresponding inner ends422mof the slots4221of the intermediate support members422. The inner ones of the projections422k(beneath dome nuts438) of the intermediate support members422also engage corresponding inner ends424jof the slots424iof the outer support members424.

Although the above-described expansion methodology is preferred, numerous variations in expansion methodology are also permissible. For instance, although it is preferred that the intermediate support members422remain stationary during the initial inward shifting of the outer support members424, proportional, non-proportional, and/or asymmetrical shifting might occur. Numerous other methodology variations permitted by the structure of the rack414, including but not limited to analogs of those described above with regard to collapse, also fall within the scope of some aspects of the present invention.

It is noted that the height of each slot4221and424iis preferably at least substantially equal and, more particularly, only slightly larger than the height (or, most preferably, diameter) of the corresponding projections420hand422k. This facilitates ease of relative sliding by the intermediate and outer support members422and424. This also facilitates stable support of the intermediate support members422on the projections420hof the foundational support member420and of the outer support members424on the projections422kof the intermediate support members422.

The design of the expandable and collapsible support rack410and, more specifically, the bag holder416described above is highly advantageous. For instance, the consistent height of the bag holder416in collapsed, expanded, and intermediate configurations facilitates its use in space-constrained areas. Its significant reduction in width through collapsing likewise provides advantages in cramped quarters, yet its span when partially or fully expanded enables significant numbers of pockets to be both easily accessible and easily viewable. Furthermore, its simple, sliding-only operation (i.e., without pivoting, turning, or other motions being necessary) provides for quick adjustments and general ease of use.

CONCLUSION

Although the above description presents features of preferred embodiments of the present invention, other preferred embodiments may also be created in keeping with the principles of the invention. Furthermore, as noted previously, these other preferred embodiments may in some instances be realized through a combination of features compatible for use together despite having been presented independently as part of separate embodiments in the above description.
