## Background
RELATED APPLICATION DATA
This application is a continuation of International Application No. PCT/US2016/050348, filed on Sep. 6, 2016, and titled “Support Assembly Joint and Applications Thereof”, the entire disclosure of which is hereby fully incorporated by reference herein in its entirety.


FIELD OF THE INVENTION
The present invention generally relates to support assembly systems and methods. In particular, the present invention is directed to a Support assembly Joint and Applications Thereof.
BACKGROUND
Furniture can be assembled in a many different ways—ways that include fasteners, glues, snaps, clips, straps, and mating joints. Many of these methods are portrayed as available to the “do-it-yourselfer” and as such are especially popular with flat-pack furniture (i.e., furniture that is principally made of shaped flat plates that are joined together). However, despite the best efforts of manufacturers, such self-assembly furniture can often be complicated to assemble, and most items require tools to put the furniture together. Moreover, often the assembly method compromises the integrity of the furniture (which is not typically made of hardwood, but instead is engineered lumber that has limited ability to maintain its integrity when screwed into), which ultimately results in failure of the furniture for its intended use. Accordingly, furniture that can be assembled and disassembled by hand, without tools or glue or other mechanisms, while still providing significant resistance to lateral and rotational movement has proved elusive.
SUMMARY OF THE DISCLOSURE
In a first exemplary aspect a support assembly is disclosed, the support assembly comprising: a first support member including a first slot, the first slot including a first tapered region and a second tapered region, wherein the first tapered region abuts the second tapered region; and a second support member including an second slot, the second slot including a third tapered region and a fourth tapered region, wherein the third tapered region abuts the fourth tapered region, and wherein assembly of the first slot and the second slot results in an intersecting joint capable of resisting lateral and rotation movement of the first support member and the second support member relative to one another.
In another exemplary aspect a chair is disclosed, the chair comprising: a first support member including a first slot, the second slot including a first tapered region and a second tapered region, wherein the first tapered region abuts the second tapered region; a second support member including an second slot, the second slot including a third tapered region and a fourth tapered region, wherein the third tapered region abuts the fourth tapered region, wherein assembly of the first slot and the second slot results in an intersecting joint capable of resisting lateral and rotation movement of the first support member and the second support member relative to one another; a base plate coupled to the first support member and the second support member; a seat for a user; and a rocking mechanism coupled to the base plate and the seat, the rocking mechanism capable of inducing lateral, longitudinal, and transverse deflection of the seat when in use by the user.

DESCRIPTION OF THE DISCLOSURE
The presently disclosed subject matter now will be described more fully hereinafter with reference to the accompanying figures, in which some, but not all embodiments of the presently disclosed subject matter are shown. Like numbers refer to like elements throughout. The presently disclosed subject matter may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Indeed, many modifications and other embodiments of the presently disclosed subject matter set forth herein will come to mind to one skilled in the art to which the presently disclosed subject matter pertains having the benefit of the teachings presented in the foregoing descriptions and the associated figures. Therefore, it is to be understood that the presently disclosed subject matter is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims.
A support assembly joint according to the present disclosure provides for easy assembly and reliably secures together structural members, such as table legs, bedframes, etc. A support assembly joint designed as described herein is suitable, for example, for use with any type of build-it-yourself or flat pack furniture where two of the pieces require a generally fixed assembly. In exemplary embodiments, the support assembly joint is formed when two structural members have cooperating multiple tapered regions so as to form a joint that is resistant to lateral and rotational movement, but does not require the use of tools, fasteners, or adhesives to assemble. As discussed in more detail below, in order to form the joint, a first structural member includes at least one downward facing slot having a plurality of tapered regions and a second structure member includes an upward facing slot having a plurality of cooperative tapered region. When assembled together, the two slots are mated and the resulting compression fit is sufficient alone to provide a stiff strong joint without the need, for example, for glue or fasteners.
A support assembly joint as disclosed herein can be useful for assembling most any structure in which two members need to be joined and multiple joints can be positioned on any single structural member to allow for the assembly of variously configured furniture items or portions thereof. For example, a first structural member can have a downward facing slot (as discussed in more detail below) proximate each end of the member to allow for mating with two other structural members that have upward facing slots. As such, the support assembly disclosed herein can be used in many applications, such as, but not limited to, furniture, bed frames, cabinets, plant holders, and the like.
Referring now to FIGS. 1 to 4, there is shown a support assembly 100, in the form of an exemplary chair or stool base, according to an embodiment of the present invention. In this embodiment, support assembly 100 includes a first support member 104 coupled to a second support member 108 by an intersecting joint 112 (discussed in more detail below with respect to, for example, FIG. 16). As shown, first support member 104 includes a leg 116 and a leg 120 that are bridged by a substantially horizontal cross-member 124 and second support member 108 includes a leg 128 and a leg 132 that are coupled by a substantially horizontal cross-member 136.
First support member 104 and second support member 108 of the presently disclosed support assembly 100 can be formed of any strong, rigid, lightweight material, such as, but not limited to, wood, wood laminate, composite wood or any other composite material, polyvinyl chloride (PVC) material, metal (e.g., aluminum, steel), and the like. Further, depending on the application, first support member 104 and second support member 108 can be solid members or hollow members. Moreover, and as discussed above, although only two support members are shown in the figures, the support assembly joint discussed herein can be used with most any number of support members.
In an exemplary embodiment, cross-member 124 and cross-member 136 each include upper surfaces 140 (140A and 140B) that are generally flat save for the inclusion of attachment features 144 that extend away from the upper surfaces of each cross-member. The configuration of upper surfaces 140 and attachment features 144 is such as to allow support assembly 100 to engage with corresponding receiving features (e.g., receiving feature 204 (FIG. 17A) and receiving feature 212 (FIG. 17B)) of an item or member to be supported atop the base, such as, but not limited to, a chair seat, a stool seat, a tabletop, and the like. Attachment features 144 can be, for example, resilient finger-like features or block-like features (see FIG. 18).
First support member 104 and second support member 108 are coupled together at an intersecting joint 112, with each support member being configured to contribute to the intersecting joint so as to make it stable and secure without the need for fasteners or adhesives. The description of the features that create intersection joint 112 is further below with reference to FIGS. 5 to 16. Moreover, more details of first support member 104 are shown and described below with reference to FIG. 8 through FIG. 9E, while more details of second support member 108 are shown and described below with reference to FIG. 10 through FIG. 11E.
Turning now to a discussion of FIGS. 5 to 7 that show various exploded perspective views of exemplary support assembly 100. In particular, FIGS. 5 to 7 show the alignment of a downward-facing slot 152 (formed in first support member 104) with respect to upward-facing slot 156 (formed in second support member 108). Downward-facing slot 152 and upward-facing slot 156 are sized and configured to mate so as to form intersecting joint 112. In an exemplary embodiment, upward-facing slot 156 and downward-facing slot 152 each include three tapered regions that cooperatively mate to form a joint that resists lateral and rotational movement and is assembled without tools, fasteners, or adhesives.
FIGS. 8 to 9E are various views of an exemplary first support member 104. FIGS. 12A, 12B, and 13 are enlarged perspective views of an upper portion of first support member 104, with a focus on downward-facing slot 152.
FIGS. 10 to 11E are various views of an exemplary second support member 108. FIGS. 14A, 14B, and 15 are enlarged perspective views of an upper portion of second support member 108, with a focus on upward-facing slot 156.
An exemplary downward-facing slot 152 is shown in more detail in FIGS. 12A, 12B-1, and 13 and an exemplary upward-facing slot is 156 is shown in more detail in FIGS. 14A, 14B-1, and 15. At a high level, downward-facing slot 152 and upward-facing slot 156 each include a plurality of cooperating tapered faces that provide a tight friction fit when first support member 104 and second support member 108 are coupled together. In a preferred embodiment, the intersecting joint 112 formed by the mating of two tapered faces on downward-facing slot 152 and two corresponding tapered faces on upward-facing slot 156 does not require fasteners or glue in order to prevent movement of the intersecting joint or to prevent separation of the intersecting joint.
In an exemplary embodiment, downward-facing slot 152 is a bi-tapered structure. As shown in FIGS. 12A, 12B-1, and 13, downward-facing slot defined by an un-tapered inside face 160, an un-tapered side face 164 (best seen in FIG. 12B-1), a top face 168, an inside tapered face 172, a side tapered face 176 (side tapered face being formed in an upper part of cross-section 124). Inside tapered face 172 has a tapered angle α that can be from about 45 degrees to about 0.001 degrees, and is more preferably between about 10 degrees to about 2 degrees. Side tapered face 176 has a tapered angle β that can be from about 45 degrees to about 0.001 degrees, and is more preferably between about 10 degrees to about 2 degrees. Together, inside tapered face 172 and side tapered face 176 provide a bi-tapered structure (also referred to herein as two tapered regions) in downward-facing slot 152 that mates with upward-facing slot 156 to couple first support member 104 and second support member 108.
In another exemplary embodiment, downward-facing slot 152 can be a tri-tapered structure. In this embodiment, downward-facing slot 152 includes a second side tapered face 178 instead of un-tapered side face 164 (as shown in FIG. 12B-2). Generally, second side tapered face 178 has a tapered angle equal to side tapered face 176, although it is understood that third tapered face and second tapered face may have different tapered angles. Together, inside tapered face 172, side tapered face 176, and second side tapered face 178 provide a tri-tapered structure (also referred to herein as three tapered regions) in downward-facing slot 152 that can mate with a similarly configured upward-facing slot 156 (described in more detail below) to couple first support member 104 and second support member 108.
Referring now to FIGS. 14A, 14B-1, and 15, there is shown close-up perspective views of an exemplary upward-facing slot 156 in cross-member 136. As with downward-facing slot 152, upward-facing slot 156 features tapered faces or walls to provide a wedge effect that ensures a tight friction fit when second support member 108 and first support member 104 are fitted together. Upward-facing slot 156 is defined by an un-tapered inside face 180, an un-tapered side face 184 (best seen in FIG. 14B-1), a bottom face 188, an inside tapered face 192, and a side tapered face 196 (the side tapered face being formed in part of cross-section 128). The angles associated with each of the tapered faces for upward-facing slot 156 are generally sized and configured to cooperate with the tapered angles found in the mating slots in downward-facing slot 152. Thus, inside tapered face 192 can have a tapered angle α that can be from about 45 degrees to about 0.001 degrees, and is more preferably between about 10 degrees to about 2 degrees. Side tapered face 192 has a tapered angle β that can be from about 45 degrees to about 0.001 degrees, and is more preferably between about 10 degrees to about 2 degrees. Together, inside tapered face 192 and side tapered face 196 provide a bi-tapered structure (also referred to herein as two tapered regions) in upward-facing slot 156 that mates with downward-facing slot 152 to couple first support member 104 and second support member 108.
In another exemplary embodiment, upward-facing slot 156 can be a tri-tapered structure. In this embodiment, upward-facing slot 156 has a second side tapered face 198 (as seen in FIG. 14B-2). Generally, second side tapered face 198 has a tapered angle equal to side tapered face 192, although, it is understood that second side tapered face and side tapered face may have different tapered angles. Together, inside tapered face 192, side tapered face 196, and second side tapered face 198 provide a tri-tapered structure (also referred to herein as three tapered regions) in upward-facing slot 156 that can mate with a similarly configured downward-facing slot 152 (as described above) to couple first support member 104 and second support member 108.
Referring now to FIG. 16, there is shown a close-up perspective view showing downward-facing slot 152 of first support member 104 in relation to upward-facing slot 156 of second support member 108 with each of the support members having a bi-tapered structure as described above. When first support member 104 and second support member 108 are fitted together, inside tapered face 172 of downward-facing slot 152 of first support member 104 is fitted against side tapered face 196 of upward-facing slot 156 of second support member 108. Further, inside tapered face 192 of upward-facing slot 156 of second support member 108 is fitted against side tapered face 176 of downward-facing slot 152 of first support member 104. As downward-facing slot 152 of first support member 104 and upward-facing slot 156 of second support member 108 are engaged, the fit becomes more and more snug or tight due to the tapered faces up until full engagement is achieved (typically when top surface 168 abuts bottom surface 188), wherein full engagement is as shown in FIG. 1. The compression fit of downward-facing slot 152 of first support member 104 with upward-facing slot 156 of second support member 108 is sufficient alone to provide a stiff, strong joint without the need, for example, for glue or fasteners.
In another exemplary embodiment, when downward-facing slot 152 and upward-facing slot 156 each include tri-tapered structure as described above, the fit between first support member 104 and second support member 108 is assisted by the fitting together of second side tapered face 198 of the second support member and un-tapered inside face 160 of the first support member and the fitting together of second side tapered face 178 of the first support member and the un-tapered inside face 180 of the second support member. The addition of the second tapered side faces on each support member can lend additional resistance to movement of the two support members relative to each other, again without the need for glue or fasteners.
Further, the joint features (i.e., tapered faces of downward-facing slot 152 and upward-facing slot 156) of intersecting joint 112 can be used in other furniture making applications, such in making bed frames, cabinets, plant holders, and the like. Moreover, a support structure may include more than one slot. For example, an exemplary support assembly could have four support structures with each support structure having a slot at the each end of each support structure. In this way the four support members can be joined to form a polygonal structure, such as a bedframe or square/rectangular furniture base. In essence, any number of support structures can be used and the location of the slots can vary so as to form many different furniture assemblies. The explanation above, with reference to a chair or stool configuration, is for exemplary purposes only.
FIG. 17A and FIG. 17B are close-up perspective views of attachment features 144 of support assembly 100 in relation to examples of receiving features of the item or member to be supported by support assembly 100. For example, FIG. 17A shows receiving features 204, which can be a slot feature in the item or member to be supported by support assembly 100. In this example, each attachment feature 144 has its own corresponding receiving feature 204. Receiving features 204 are sized according to the size and/or geometry of attachment features 144 and may include a latch 208 so as to maintain the connection between the attachment feature and the receiving feature. In another example, FIG. 17B shows a receiving feature 212 that is designed to receive the pair of attachment features 144, which, in this embodiment, may have resiliency so as to maintain the connection between the attachment features and the corresponding receiving features. That is, receiving feature 212 is an enlarged slot compared to receiving features 204 of FIG. 17A, wherein receiving feature 212 is sized to receive the two paired attachment features 144.
FIG. 18 is a perspective view showing another example of the attachment features, attachment features 216, of support assembly 100. In this example, instead of a pair of narrow finger-like attachment features 144, larger block-like attachment features 216 are provided. Receiving feature 212 as shown in FIG. 17B may be well suited for use with these larger block-like attachment features 216.
The presently disclosed support assembly 100 is not limited to arch-shaped support members as shown and described herein. The support members can be any shape suitable for supporting an item or member, such as, but not limited to, arch-shaped, reversed U-shaped, wicket-shaped, and the like. For example, FIGS. 19A and 19B show front views of an example of a wicket-shaped first support member 104 and a wicket-shaped second support member 108, respectively.
Additionally, the cross configuration of the presently disclosed support assembly 100 is not limited to a 90-degree relationship of first support member 104 and second support member 108 as shown and described herein. Other angles are possible by tailoring the sidewalls of downward-facing slot 152 of first support member 104 and of upward-facing slot 156 of second support member 108. For example, FIG. 20 shows a top view of another example configuration of first support member 104 and second support member 108 that is something other than 90-degrees. In this embodiment, one or more of the tapered faces discussed above with respect to downward-facing slot 152 and upward-facing slot 156 may also include a bevel so as to accommodate the angle of the connection between first support member 104 and second support member 108.
Turning now to FIG. 21, there is shown an exemplary embodiment of support assembly 100 in use. More particularly, FIG. 21 shows a perspective view of an exemplary exercise chair 300 that is formed using a support assembly with an intersecting joint, such as support assembly 100.
Exercise chair 300 includes a base plate (or platform) 304 that sits atop and is coupled to support assembly 100. Base plate 304 can be, for example, a wood or wood laminate platform. The underside of base plate 304 includes receiving features, such as slots (not shown), to which attachment features 144 of first support member 104 and second support member 108 can engage. In one example, attachment features 144 can be resilient, such that they can be snap-fitted into the receiving features (e.g., slots (not shown)) of base plate 304.
Further, exercise chair 300 can also include a rocking mechanism 308 arranged between base plate 304 and a seat 312. In this example, rocking mechanism 308 includes a pair of eccentric bicylinder rocking members 316. Each of the eccentric bicylinder rocking members 316 includes a first surface 320 and a second surface 324 arranged in an eccentric bicylinder shape as shown. More particularly, FIG. 21 shows that eccentric bicylinder rocking mechanism 316 has a first contact line (CL1) that runs along the apex of surface 320 and a second contact line (CL2) that runs along the apex of surface 324. In exercise chair 300, eccentric bicylinder rocking mechanism 316 is arranged, for example, such that the second contact line (CL2) of eccentric bicylinder rocking member 316 is oriented substantially perpendicular to first contact line (CL1). Seat 312 can be fastened along the first contact line (CL1) and base plate 304 can be fastened along the second contact line (CL2) of eccentric bicylinder rocking member 316, thereby allowing seat 312 to rock, wobble, and/or swivel with a side-to-side rocking motion, a front-to-back rocking motion, or both a side-to-side rocking motion and a front-to-back rocking motion.
In another exemplary embodiment, exercise chair 300 can include one half of the eccentric bicylinder rocking mechanism 316 only, such that the eccentric bicylinder rocking mechanism has a flat bottom side (not shown). In this embodiment, seat 312 is fastened along the first contact line (CL1) and base plate 304 is fastened to the flat bottom side of the eccentric bicylinder rocking mechanism 316. In yet another exemplary embodiment, rocking mechanism 308 is a hollow or solid hemispheric- or dome-shaped rocking mechanism. In yet a further exemplary embodiment, rocking mechanism 308 can be an arrangement of halfpipe members.
In another exemplary embodiment, aspects of exercise chair 300 can be based upon the exercise chair described in U.S. patent application Ser. No. 14/947,675, entitled “Exercise Chair,” filed on Nov. 20, 2015, which includes a rocking assembly that further includes a rocking mechanism that sits between a base plate or platform and a seat, and is incorporated by reference for its discussion of the same.
A support assembly 100 as discussed herein can also be added to by other features known in the art; for example, wheels or casters, foot rest bars, and shelves (none of the aforementioned shown) can be added to the legs of the support assembly to increase utility of the support assembly.
While the support assembly joint described herein has been placed in the context of the construction of furniture, there are many other applications for the support assembly joint where a strong connection between two items is needed and it is preferred (or necessary) that fasteners or adhesives not be used. These applications can include, but are not limited to, nanotechnology structures (fastening, joining, connecting and fusing of nanostructures that are too small for mechanical fasteners), architecture materials (e.g., beams, members, bridge components, for use in, for example, timber frame houses, modular metal structures, etc.), construction materials (e.g., concrete castings, iron fittings), tooling, machinery, and construction equipment (e.g., quick disconnects, power transmission equipment, driveshafts), injection molded plastic products (replacing lips, tabs, hooks, and bulge features currently employed), automobile (driveshafts, connects to trailers and other towable items), aerospace, and other transportation related parts, electronic equipment such as contacts and sockets, storage applications (e.g., support structures for containers, shelving, organizers), cookware (connecting handles to pots and pans), packing materials such as cardboard containers, safety equipment (e.g., stacking, nesting gear, road barriers).
The size and/or materials of construction of the presently disclosed support assembly 100 can vary depending on the item or member to be supported, wherein the overall size and/or weight of the item or member to be supported can be considered.
