PAPER CLIP

Abstract: A clip (10) to grip paper is adapted to carry advertising indicia (18). The clip (10) comprises two cooperating gripping jaws (12) and (14). One or both of the jaws (12) or (14) is formed with a thin planar land such that the land and jaw are formed as a single piece thereby monolithically to define a clamping plane. A resilient element (16) maintains the jaws in a given alignment and causes the jaws (12) and (14) to exert a clamping pressure. Each planar face (14a) and (14b) of the plate-like clamping plane provides a means on which the advertising indicia (18) is placed.

Description: PAEER CLIP This invention relates to paper clips , and more par¬ ticularly , the invention relates to a planar clip having an integral flat to carry advertising indicia . Paper clips come in a myriad of constructions . Gen¬ erally, in its most ubiquitous form, the clip is a wire device formed of internesting elongate wire loops . Because this clip is used so extensively, it would seem desirable to include some means on the clip to convey advertising. However , because the aforementioned wire clip is an ultra low cost item, the means by which the advertising is displayed also must be low. cost . Then, too, to be successful, the means used to carry or display the advertising indicia must remain on the clip in all situa¬ tions , and it must not interfere with fastening action. The prior art shows numerous devices that can be used to convey advertising indicia and that can be applied to paper clips . Generally, such prior devices are discrete assemblies that must be attached or clipped onto the clip , and thus can be displaced and lost . Moreover, most of these devices appear to cost more than the clip itself . The present invention overcomes the problems outlined above . In general, the present invention comprises a detachable clip that has a pair of cooperating jaws one or both of which are formed of thin plate-like members . The plate-like j aw defines a monolithic gripping plane or planar flat that is generally of elongate configuration . A resilient biasing element , disposed in the plane of the' clip , maintains the j aws in a given alignment and causes the jaws to exert a clamping pressure . In one emb.odiment of the present invention, the gripping plane or flat comprises the entire jaw, and, in another embodiment, the flat comprises only a portion of the jaw. In either case, advertising indicia can be placed on either planar surface of the flat. The planar nature of the gripping plane of the present invention acts to increase the fastening action of same when compared to a conventional wire jaw, and the inventive jaw tends to reduce localized deforma¬ tions of the paper when compared to such conventional jaws. It is therefore an object of the present invention to provide a paper clip that is low in cost and that can be used to display advertising indicia. It is another object of the present invention to provide a paper clip having means with which advertising can be dis¬ played but wherein such means will not interfere with clip operation. It. is a further object of the present invention to provid a paper clip having means with which advertising indicia can be displayed, and that is readily adapted to fabrication with conventional wire clips . It is another object of the present invention to provide a paper clip wherein one or both of the gripping jaws are forme of a thin plate-like member or flat, .and wherein this member provides a relatively large surface area with which to grip the paper detachably. Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed SUBSTITUTE SHEET ( O P fur purposes of illustration only, and not as a definition of - the limits of the invention for which reference should be made to the appending claims . In the drawings, wherein the same reference numeral denotes the same element throughout the several views: Fig. 1 is a plan view of one embodiment of a clip con¬ structed according to the present invention showing the in¬ ventive gripping jaw applied to a conventional wire clip; Fig. 2 is a transverse sectional view taken along the line 2-2 of Fig. 1 and looking in the direction of the arrows to show the integral or one piece construction of a gripping jaw, for the purposes of clarity the jaws are separated slightly;- Fig. 3 is a view similar to Fig. 2 showing a modified • form of the inventive clip, in Fig. 2 the clip of Fig. 1 is shown with each jaw constructed of a thin monolithic gripping p lane ; Fig. 4 is a plan view of another embodiment, of a wire clip constructed according to the present invention, the clip is, for the most part, in the form of a coil or spiral with the planar flat seen comprising the central portion thereof; Fig. 5 is a view taken along the line 5-5 of Fig.- 4 and looking in the direction of the arrows, for purposes of clarity the coil sections are spread slightly relative to an imagined longitudinal axis and they are about to engage the papers to be fastened; Fig. 6 is a plan view of a further embodiment of a clip constructed according to the present invention showing the inventive gripping flat comprising one jaw of a conventional wire clip; ' Fig. 7 is a sectional view taken along the line 7-7 of Fig. 6 to show, in detail, the integral construction of the gripping plane or gripping jaw, for purposes of clarity the jaws are separated slightly; Fig. 8 is a plan view of another embodiment of a clip constructed according to the present invention show r ing the plate-like planar flat or land integrally attached to only a portion of one jaw of a conventional wire clip; Fig. 9 is a sectional view taken along the line 9-9 of Fig. 8 to reveal, in detail, the integral construction of the " planar flat; Fig. 10 is another embodiment of a clip constructed according to the present invention, the clip is, so to speak, of reversed construction when compared to Figs. 4 and 5 3 that is, the coil spirals radially inwardly along a path that has a convoluted center-directed convergence; Fig. 11 is a sectional view taken along the line 10-10 of Fig. 10 and looking in the direction of the arrows, for purposes of clarity the coil remains viewed in elevation, coil sections are spread slightly along an imagined longi¬ tudinal axis, and they are about to engage the papers to be fastened; and, Fig. 12 is a sectional view similar to Fig. 11 showing a modified form of the clip seen in Figs. 10 and 11. In detail now and referring to the drawings, Figs. 1 and 2 show one embodiment of the present invention. The clip, indicated generally by reference numeral 10, is defined by a J SUBSTITUT O pair of cooperating internesting gripping jaws 12 and 14. In the embodiment shown, the outer or relatively larger jaw 12 is, in plan view, U-shaped, and as such, integrally is formed with parallel opposed longitudinal sides 12a and 12b that are connected by a curved portion 12c. With this construction, jaw 12 substantially encloses a planar void 12d, as shown. The inner or relatively smaller jaw 14 is, in plan view, generally elongate or, more or less, of U-shaped configuration. Jaw 14 is of thin plate-like planar construction and, as such, is defined by two planar surfaces, namely, surface 14a and surface 1 b, Planar jaw or flat 14 is of monolithic unitary construction with the planar surfaces thereof extending from one respective perimetric longitudinal edge of the jaw to the other. A connecting U-shaped section Iβ, preferably of appropriate temper, is,* on one end, attached to and is integral with what is shown as a transverse or shorter edge of jaw 14. The other end of U-shaped element 16 is integral with and attached to side or leg 12b of jaw 12, as shown. Resilient connecting section 16 is disposed in the plane of clip 10, more or less, and it orients jaws 12 and 14 so that the same align generally longitudinally with the latter jaw nesting in the planar void of the former. Thus, when the clip is not being used, jaw 12 accommodates jaw 14 so that both jaws lie in a common plane. Moreover, section 16 is adapted to exert a clamping pressure vrtien the jaws are sep¬ arated or skewed slightly during operation of the invention which will be described below. Advertising indicia 18 can be placed on either one of SUBSTIT ' O PI the two surfaces of gripping plane ' 14. This can be accomplish in a variety of ways . For example , advertising indicia 18 can be embossed on either or both surfaces l4a and 14b by stamping or molding. Or, indicia 18 can be placed on these surfaces by printing, silks creening, and like processes . Operation and use of the embodiment of Figs . 1 and 2 is " straight- forward and needs little dis cussion. Suffice it to s ay , however, that the papers to be fastened are inserted between the separated or slightly skewed jaws 12 and 14 to be held clampingly therebetween by the compressive action of the jaws . Depending on the direction of separation of one jaw relative to the other, one surface of jaw 14 will be place on the outside of the paper carrying with it advertising indicia 18. It will be apparent , too, that when compared to conventional wire clips , either planar face presented by j aw or gripping plane 14 provides for an increase in the gripping power of the clip . And, the planar face or surface presented by this j aw acts to distribute the compressive load thereof over a greater area and this tends to minimize localized de¬ formations of the paper . In the embodiment shown in Figs . 1 and 2 , the relatively smaller j aw, jaw 14, is shown as being of monolithic plate¬ like construction . However, it is to be understood clearly that the relatively larger aw , jaw 12 , can be formed as the monolithic plate-like gripping plane , and the smaller jaw , jaw 14 , can be of open wire construction . Within the dis¬ closure of this invention , this is merely a matter of choice . However, when the re latively larger j aw is made plate-like and thus defines a monolithic gripping plane , and the other smaller jaw is of open wire form, the geometry of this configuration will not permit the j aws to interfit and occupy a common plane . Instead, element 16 will cause the j aws to overlie , so to speak , such that the facing surface of the larger j aw or gripping plane will be in pressured parallel engaging = contact with facing perimetric regions of the wire that defines the smaller j aw . Indeed, as will be disclosed in the imme¬ diately following embodiment, both jaws can be of plate-like mono li thi c cons t rue tion . Turning now to Fig. 3 there is shown , in cross-section, a modified form of the clip shown in Fig. 1. In Fig. 3 each j aw of the clip is comprised of a monolithic plate-like gripping plane that , in plan view, has an outline that re¬ sembles a corresponding j aw of Fig. 1. Being more specific , the clip, indicated generally by reference numeral 310 , is comprises of a relatively larger monolithi c plate-like clamping jaw 312, and a relatively smaller monolithic plate-like clamp¬ ing jaw 31 . Each one of these j aws or gripping planes is defined by a pair of rod-like parallel spaced perimeter-defin¬ ing longitudinal regions 20 integrally formed with associated plate-like gripping planes 312 and 314 , as shown . Each gripping plane is further defined by respective inboard substantially planar surfaces 312a and 3l4a , and a respective outboard sur¬ face 312b and 3l4b . As des cribed with reference to Fi s . 1 and 2 , a connecting U-shaped se ction 16 , preferab ly of appropriate temper , is connected to a corresponding edge of a respective gripping plane so that the planes align generally -ST3 El ~ longitudinally . Moreover, element 16 places the respective inboard or opposed surfaces of each jaw in pressured parallel- engaging contact. It will be observed that gripping plane 312 has a slight center directed taper and bows outwardly relatively to the plane defined by rod- like perimeter defining regions 20. That side of gripping plane 31*4 that immediately faces gripping plane 312, that is, surface 3l4a, is generally flat while the outwardly facing side of plane 31^ 3 that is, surface 3l4b, bows outwardly relatively to the plane defined by its rod-like perimeter-defining regions 20. A plurality of minute surface discontinuities 3l4c and be formed on inboard surface 3l4a of plane 314 to roughen or texture the last- mentioned surface and thereby increase the gripping power of clip 310. Advertising indicia 18 can be placed on outboard surfaces 312b and 3l4b of respective gripping planes 312 and 314, as shown. Operation and use of the clip of Fig. 3 is straight¬ forward and, more or less similar to the use and operation described with reference to Figs. 1 and 2. However, it will be apparent that, when not in use, jaws 312 and 31 do not interfit but rest in back-to-back pressure engagement. Or, put another way, the inboard opposed surfaces of each jaw are in parallel engaging contact. The roughened texture afforded by surface discontinuities 3l4c add to the overall fastening action of clip 310. Turning now to Figs . 4 and 5 there is shown another embodiment of a clip constructed according to the present invention. The clip, indicated generally be reference numeral 22, is defined by a central plate-like gripping plane or planar land 24 that is, in plan view, generally circular. A spirally wound appropriately tempered internesting planar coil 26 is, on one end, attached to the rim of land 24, while the other end of coil 26 is free. As can be seen in Fig. 4, coil 26 spirals radially outwardly from and around the rim of central planar disc 24 and is, normally, in the plane thereof. Hence, when not in use, coil 26 is more or less disposed in the plane of disc 24. Advertising indicia 18 can be placed on either or both planar sides of disc 24. Operation and use of the clip of Figs . 4 and 5 is straight- forward. Sections of coil 26 are displaced in a direction orthogonal to the plane of disc 24 to thereby spread adjacent coil sections or coil-planes along an imagined longi¬ tudinal axis. The papers, 28, to be fastened, seen edgewise and in phantom in Fig. 5 _ . are, in one case, inserted between the slightly spread adjacent contiguous interfitting coil surfaces of spirally formed element 26. It will be apparent that opposed contiguous perimetric coil surfaces 26a and 26b compressingl engage papers 28 while orienting advertising indicia 18 in full view. In another case, not shown, papers 28 can be inserted between one face of planar land 24 and the immediately adjacent coil section or surface of spirally wound element 26. In this last-mentioned case, the papers would be grasped by . compressive action between the one face of land 24 and the aforesaid adjacent coil section. In the embodiment of Figs. 4 and 5 3 the advertising indicia can be placed on both planar sides of land 24, as noted above, to insure that an advertising message would ^JREA^ OMPI re main in view even if coil 26 were moved "upwardly" rela¬ tively to the plane of disc 24. And, while coil element 26 is shown as comprised of spirally wound wire, element 26 can be comprised of spirally wound flat stock * . When such is the case, the advertising indicia can be carried on the planar surfaces of this flat stock. Turning now to Figs. 6 and 7 > there is shown another embodiment of the present invention. A clip, generally indicated by reference numeral 30, is of conventional pro¬ file, and thus has a pair of V-shaped gripping jaws or limbs 32 and 34 that are in criss-crossed back-to-back disposition. The V-shaped or triangularly formed limbs are connected integrally at their acute ends by a length of wire 3 to form what resembles a base. Wire element 36 is tempered appro¬ priately and thereby resiliently biases one limb or jaw against the other. In accordance with the present invention, limb 34 is formed from thin plate-like stock and thus has an inner planar surface 34a, and an outer planar surface 34b. Hence, limb 34 defines a generally flat gripping plane of monolithic or unitary construction that, in plan view, is of triangular configuration. Limb 32 is of open wire construction. In actuality, limb or jaw 3 is an integral extension of wire section 36. The wire comprising or defining limb 3 eventually is bent back upon itself in such manner as to form a V-shaped wire jaw that encloses a planar void 32c, as shown. With this construction a portion of the inboard planar surface of jaw 34 is in pressured parallel engaging contact with a plan portion of jaw 32 along a criss-cross path. Thus, by means element 36 the facing regions of jaws 32 and 3*-* are adapted to exert a clamping pressure. On the outboard surface 34b of V-shaped gripping plane 3*^ > aidvertising indicia 18 can be placed. Operation and use of clip 30 is straight-forward. The papers to be fastened are inserted between opposed or facing jaws compressingly to be ' clamped therebetween. The increased contact area afforded by gripping plane 3^ or, more precisely, surface 34a, operates to ' increase the gripping power of clip 30 when compared to clips of conventional design. And, the outboard planar face 34b of gripping plane 34 provides a relatively large surface on which advertising indicia 18 can be placed. In the embodiment of Figs. 6 and 7 3 and as noted above, one jaw of the clip is shown as comprised of a monolithic plate-like member while the other jaw is merely of bent wire construction. However, the invention is not to be limited to this design because each jaw can be formed as a monolithic plate-like member. Turning now to Figs. 8 and 9 S there is shown another embodiment of a clip built according to the present invention. A wire clip, generally indicated by reference numeral 38, is more or less, of conventional construction. Hence clip 38 is formed from a single length of wire 40 which is bent to form opposed, longitudinally aligned internesting elongate U-shaped • jaws 42 and 44. Each U-shaped jaw is connected integrally by a resilient curved section or bight portion 46. In accordance with the present invention, a planar land or flat 48 is disposed between the opposed longitudinal wire sections or sides that comprise the longitudinal perimeter of jaw 44. The ends of flat 48 integrally are formed with the aforesaid parallel opposed longitudinal sides of jaw 44, thus forming a planar bridge, so to speak, between the longitudinal sides of U-shape jaw 44. Flat 48 is defined by one planar surface 48a, and another planar surface 48b both of which are, more or less, in the plane of jaw 44, as seen in Fig. 9- When comparison is made between Figs. 1 and 8 it will be noticed that flat 48 is disposed or covers only a portion of the longitudinal length of jaw 44. Advertising indicia can be placed on either planar surface of flat 48. Operation and use of clip 40 should be readily apparent, and so needs no discussion here . In the embodiment of Figs. 8 and 9 _, planar land or flat 48 is shown disposed on relatively smaller jaw 44. But the invention is not to be so limited because the land can be placed on either jaw, or on both of them. Indeed, the land need not extend between both longitudinal perimetric-defining wire sides of jaw 44 as it is shown in Figs. 8 and 9, for a land (48c, seen in phantom in Fig. 8) integrally can be attached to one longitudinal side of jaw 44 in a type of cantilever disposition. Or, the land .can be positioned con¬ tiguous to the leading or curved section of either jaw and integrally attached thereto. In fact, it is within the scope of this invention to position a flat or plate-like member with the void of curved element or bight portion 46 and be integral therewith. Although this last- described position of the flat -^U O might interfere with clip operation to some degree. Turning now to Figs. 10 and 11 there is shown another embodiment of a clip constructed according to the present invention. The clip, indicated generally by reference numeral 1022, is defined by . a monolithic central planar gripping flat or disc 1024 that has an Inboard planar face 1024a and an outboard planar face 1024b . A spirally wound appropriately tempered resilient planar coil 1026 is, on one end, attached- to one planar face of disc 1024 preferably near the rim thereof. The other end of coil 1026 is free. As can be seen in Fig. 10, coil 1026 spirals radially inwardly along a path that has a convoluted center-directed convergence. Owing to the planar construction of coil 1026 , the free end thereof Is normally disposed adjacent to the opposed planar face of disc 1024, that in the embodiment shown, is face 1024a. Thus, when not in use, the plane of coil 1026 is more or less disposed adjacent to face 1024a. Advertising indicia 18 can be placed on either or both planar faces of disc 1024. Operation and use of the embodiment of Figs. 10 and 11 is straight-forward and, for the most part, similar to the manner of operation described with reference to Figs. 4 and 5. Hence, in one case, the papers to be fastened, 28, are inserted between opposed, longitudinally displaced coil sur¬ faces 1026a and 1026b compressingly to be held therebetween. In another case, not shown, papers 28 can be inserted between face 1024a of flat 1024 and the immediately adjacent coil section or surface of spirally wound element 1026. Turning now to Fig. 12 there is shown in cross-section - • gtS EA - a modified form of the clip seen in Figs. 10 and 11. A clip, indicated generally by reference numeral 1222, is formed of a washer-like planar central region or disc 1224 having a central aperture 1224a. Aperture 1224a is defined by an in¬ board annular rim 1224b. Circular disc 1224 has two planar faces 1224c and 1224d. A spirally wound appropriately tem¬ pered resilient planar coil 1226, similar to coil 1026, is, on one end, attached to -aperture- defining rim 1224b of disc 1224. The other end of coil 1226 is free. In plan view, coil 1 >26 spirals radially Inwardly along a path that has a convoluted center directed convergence. Owing to the planar construction of coil 1226, the free end thereof is normally disposed in the planar void of member 1224 that defines apertu 1224a. Thus, when not in use, the plane of coil 1226 aligns with or is in the plane of disc 1224. Advertising 18 can be placed on either or both planar faces 1224c and 1224d. Operation and use of the clip of Fig. 12 is straight¬ forward, and for the most part, similar to the manner of operation and use discussed with reference to Figs. 10 and 11. It will be apparent, though, that coil 1226 can move relatively "upwardly" or "downwardly" with respect to member 1224 to thereby place the coil on either one planar side of member 1224 or the other. With this construction, either one of these planar sides can cooperate with coil 1226 to clamp papers 28. Moreover, when comparison is made between Figs. 11 and 12, it will be seen that in Fig. 12, since the planes of element 1226 and member 1224 align, due to the accommodation of the former in the void of the latter, clip 1222 will have a nested or unused thickness generally no greater than the thickness of member 1224. In plan view coil 1226 of Fig. 12 looks like coil 1026 of Fig. 10, although as noted above, the larger diameter end of coil 1226 is attached to inboard rim 1224b while the other end of coil 1226 is free. In accordance with the present inven¬ tion, a planar land or flat 1228, seen in phantom in Fig. 12, can be attached to the aforesaid free end of coil 1226.- In plan view land 1228 would be preferably circular, and in elevation, oriented generally parallel to the plane of washer 1224. Land 1228 would then provide a convenient finger rest that can be used to reposition and rebias spring 1226 if the spring becomes deformed plastically. In the embodiments of Figs. 10, 11 and 12 the coil element is shown as comprised of spirally wound wire, but as in earlier described embodiments, the coil element can be comprised of spirally wound flat stock with the advertising Indicia placed on the planar face of this flat stock. In all of the foregoing embodiments, it is possible to fabricate the clips from metal stock in a single process or stamping. Or, the clips can be fabricated from plastic and made by injection molding or stamping. In fact, it is feasible to fabricate the inventive clips as a composite structure. For example, gripping plane 14 can be fabricated from plastic, and element 16 and jaw 12 can be made of small diameter steel rod or wire. While only a few embodiments of the present invention have been shown and described, it is to be understood that many changes and modifications can be made hereto without departing from the spirit and scope hereof.
