DETAILED DESCRIPTION OF THE INVENTION

(14) Before describing the disclosed embodiments of this technology in detail, it is to be understood that the technology is not limited in its application to the details of the particular arrangement shown here since the technology described is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation.

(15) In various exemplary embodiments, the technology described herein provides a device, system, and method for a chair wedge. The chair wedge generally includes a first tier horseshoe-shaped wedge and a second, lower tier, recessed within the first tier and within which a cavity is defined and therefore configured to receive the leg or foot portion of a stackable folding chair when it is in a folded position and therefore to aid in the prevention of falling stacked chairs when multiple such chairs are folded and stacked adjacent to one another.

(16) Referring now to the Figures, a chair wedge 10 is shown. The chair wedge 10 is configured to maintain stacked folding chairs 38 and to prevent the chairs 38 from falling. Because stacks of folding chairs 38 tend to fall over and cause disruptions, including minor injuries and distractions, utilization of one or more chair wedges 10 aids in the prevention of chair falls. By way of example, and as depicted in FIG. 10, chairs 38 are shown sliding from what was once a stacked position with all chairs propped up against a wall surface. Also, by way of example, and as depicted in FIG. 11, chairs 38 are shown secured by a pair of chair wedges 10. This application of the chair wedges 10 keeps chairs 38 in a safe, upright position and aids in the prevention of falling stacked chairs.

(17) The chair wedge 10 includes a first tier 14. The first tier 14 has a downward sloped first top surface. The downward sloped first top surface extends from a first tier top rear edge, where first tier 14 meets outer rear edge 12, to a first tier top front edge, where right side ramp 26 and left side ramp approach the base 18.

(18) The chair wedge 10 includes a second tier 16. The second tier 16 is recessed within a center portion of the first tier 14. The second tier 16 also has a downward sloped second top surface. The downward sloped second top surface extends from a second tier top rear edge where first tier inner rear wall 20 meets second tier 16, to a second tier top front edge where second tier 16 nears base 18. First tier inner sidewall 22, first tier right outside wall 28, and first tier left outside wall 30 all are tapered in height as they each approach the base 18. The downward sloped second top surface is at a lesser angle relative to a base surface than is the downward sloped first top surface. This novel two-tiered arrangement provides for an interior recessed area in which to receive a chair leg.

(19) The chair wedge 10 includes a cavity. The cavity is formed in a space differential between the downward sloped first top surface of first tier 14 and the downward sloped second top surface of second tier 16, wherein the second tier 16 is recessed within a center portion of the first tier 14. The cavity provides a receiving area for the foot of a chair or a chair leg.

(20) The chair wedge 10 includes first tier inner rear wall 20. The first tier inner rear wall 20 is defined at an inward most portion of the cavity. The chair wedge 10 includes first tier inner right side wall 32 and first tier inner left side wall 22, each extending from the first tier inner rear wall 20. Each of the first tier inner rear wall 20, first tier inner right side wall 32, and first tier inner left side wall 22 extends vertically, downwardly from first tier 14 to second tier 16. The first tier inner rear wall 20 in combination with the cavity is configured to stop a chair leg from further movement when placed within the chair wedge 10.

(21) The cavity and first tier inner walls are best depicted in FIGS. 4 and 8. FIG. 4 is a front planar view of the chair wedge 10. FIG. 8 is a side cross-sectional view of the chair wedge, along line 8-8 in FIG. 2. Both figures illustrate the cavity formed in a space differential between the downward sloped first top surface of first tier 14 and the downward sloped second top surface of second tier 16. This cavity is formed configured to receive the leg of a stackable folding chair.

(22) In at least one embodiment, the chair wedge 10 is generally a horseshoe shape. This horseshoe-shaped chair wedge 10, as depicted for example in FIG. 1, is downwardly sloped from a toe area, intersection of outer rear edge 12 and first tier 14 (the toe area of a traditional horseshoe) to a heel area, the portion of the chair wedge 10 closest to the base surface (the heel area of a traditional horseshoe). In this embodiment, the first tier 14 of the chair wedge 10 is generally a horseshoe shape downwardly sloped along right side ramp 26 and left side ramp 24 to the heel area. In this embodiment, the second tier 16 of the chair wedge 10 is recessed within the horseshoe-shaped first tier 14.

(23) The chair wedge 10 includes a base 18. In at least one embodiment, the base 18 of the chair wedge 10 includes a non-slip bottom surface such that it remains in place even with the weight of one or more stackable, foldable chairs 38 placed within the chair wedge 10, as depicted in FIG. 11, for example.

(24) As depicted for example in FIG. 3A, a non-slip bottom surface is shown. In at least one embodiment, the non-slip bottom surface further includes a textured pattern 34 to provide further resistance to sliding for the chair wedge 10. The textured pattern 34 covers the entire base 18 in at least one embodiment. In alternative embodiments, the textured patter 34 covers predetermined portions of the base 18.

(25) In at least one embodiment of the chair wedge 10, the base 18 is rubber. In at least one embodiment of the chair wedge 10, the base 18 is plastic.

(26) In at least one embodiment of the chair wedge 10, the base 18 is integrally formed with the chair wedge 10. In at least one embodiment of the chair wedge 10, the entire chair wedge 10 is integrally formed and is plastic.

(27) In at least one alternative embodiment, the base 18 is generally hollow. The generally hollow base 18 includes, for example, cavity area 48. In this embodiment, the base 18 also includes at least one structural ridge member to provide support to the first tier 14 and the second tier 16. The structural ridge member, such as first horizontal bar 44, second horizontal bar 42, and horseshoe-shaped bar 40, is disposed on underside surface of the chair wedge 10 to provide support to the chair wedge 10 from a base surface upon which the chair wedge 10 rests.

(28) As depicted for example in FIG. 3B, the base 18 is generally hollow. The structural ridge members: first horizontal bar 44, second horizontal bar 42, and horseshoe-shaped bar 40, each provide structural support to the chair wedge 10. The areas between the structural ridge members are hollow.

(29) The chair wedge 10 also includes an outer rear edge 12. The outer rear edge 12 includes a downward sloped third surface that slopes in a direction that is opposite that of both the downward sloped first top surface and the downward sloped second top surface. This provides increased structural stability to the chair wedge 10 when downward forces from multiple folded stackable chairs 38 are applied to the chair wedge 10.

(30) In at least one embodiment, the chair wedge 10 includes a tether 36. In various embodiments, the tether 36 is selected from cord, wire, or leather. The tether 36 is securely fastened to the chair wedge at a point on the chair wedge 10 that will not interrupt the general operation of the chair wedge 10. The tether 36 is coupled to the chair wedge 10. The tether 36 is configured for coupling to a second chair wedge 10 such that a pair of chair wedges is readily available to use as a stop for a stack of stackable folding chairs, one on each side of the chair legs. As depicted specifically in FIG. 9, a pair of chair wedges in tether together via tether 36.

(31) Although this technology has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples can perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the technology disclosed herein and are intended to be covered by the following claims.
