This situation may be encountered with wheelchairs, in portable folding chairs, and with other types of seating.
- the adapter plate 35 may present an upwardly facing surface which is considerably greater in width along its length than the armrest 37 .
- the length of the cushion 36 and its component parts will be understood to be that dimension aligned with the length of the armrest 37 .
- the armrest 37 may be fabricated from tube stock of nominal diameter of one inch, whereas the adapter plate 35 may extend lateral reach along the armrest 37 to a lateral span of three or four inches.
- the three or four inch wide platform gives the cushion 36 a sufficiently wide rigid seat so as to enable the cushion 36 to present a generally flat, planar surface for receiving the forearm of the user when the adapter plate 35 is installed to the armrest 37 .
- the adapter plate 35 would abut the armrest 37 and be secured thereto by bolts 43 and 45 This both increases comfort, since the forearm may be supported over a considerably greater surface area than would be the case if the cushion 36 were mounted directly to the tubular armrest 37 , and also stabilizes the cushion 36 which may be difficult to mount to a relatively small, circular tube.
- the upwardly facing surface of the adapter plate 35 bears hook and loop fastening material 40 which releasably mates with corresponding hook and loop material 39 disposed on the underside of the cushion 36 .

- the hook and loop material 39 may be disposed on the underside of the wings 42 . In the absence of discrete wings 42 , the hook and loop material 39 could be disposed on the underside of the cover 52 of the cushion 36 , or of the cushion 36 itself in the absence of the cover 52 .
- the wing or wings 42 provide lateral support for the cushion and help to maintain the position of the cushion upon the armrest. It is contemplated by the inventor that the wing 42 structure shown in FIG. 14 , and as described fully above, would have the same benefit when used with the cushion shown in FIG. 7 . In the version shown in FIG. 7 , the wing 42 would attach to the outside surface of the cushion in the same manner as described for FIG. 14 . And in the case when only one wing is attached to the cushion, to better achieve the lateral support, the cushion 36 is positioned on the armrest so that the wing 42 contacts the inner surface of the armrest (toward the seat).
- the cushion In this position the cushion is able to withstand the lateral forces created when a user's arms move away from the body—as is typically the case in a seated position.
- a pair of wings on opposite sides provides the desired enhanced lateral support.
- the adapter plate 35 may be fastened to the armrest 37 by the bolts 43 , 45 which pass through holes 45 , 46 formed in the armrest 37 .
- the bolts 43 , 45 may thread to holes 46 , 47 formed in the adapter plate 35 , or may thread to a raised boss (not shown) which may be formed integrally with the adapter plate 35 if desired.
- the bolts 43 , 45 may be sufficiently large and secure so as to hold the adapter plate 35 rigidly in place on the armrest 37 in a manner which opposes rocking and other disruptions under conditions of ordinary use.
- the bolts 43 , 45 and their corresponding threaded holes 46 , 47 collectively comprise a fastener capable of securing the adapter plate 35 to the armrest 37 .
- the armrest 37 may be deformed to better seat the heads of the bolts 43 , 45 by providing a non-arcuate surface. Deformation is indicated by valleys 48 , 50 formed in the armrest 37 .

Description
- This application claims the benefit of the filing date of U.S. Non-Provisional application Ser. No. 12/433,045, filed Apr. 30, 2009, the contents of which are incorporated herein by reference.
- In present day situations persons often work at computer stations or desks for long periods of time, in which case the arms of the chair in which they are seated provide a rest for the user's elbows. Armrests typically present a surface of hard or relatively hard material, which is uncomfortable for the user, especially over a long period of time. Thus, it is known in the prior art to provide auxiliary pads for attachment to the upper surface of the chair arms. Such auxiliary pads are shown in U.S. Pat. No. 1,247,547, U.S. Pat. No. 5,700,053, U.S. Pat. No. 6,578,914, and U.S. Pat. No. 7,431,396. However, these devices all suffer from deficiencies with regard to the flexibility of their structures and manners of attachment to the armrests of the chair, which limit the comfort they provide to the user and the flexibility to allow easy attachment to a variety of armrest shapes. This invention alleviates the problems present in the prior art.
- The present invention provides a cushioned elbow support attachment for placement upon the upper surface of the armrest of a chair having an elongated sack-like cushion made of material having elastic properties and having a bottom surface. A plurality of smooth edge rounded pellets are contained in the cushion. Attachment means secure the cushion in place on the armrest with the bottom surface of the cushion in juxtaposition with the upper surface of the armrest.
- The present invention further provides a cushioned elbow support attachment for placement upon the upper surface of the armrest of a chair, having an elongated sack-like cushion made of material having elastic properties and having a bottom surface. A plurality of smooth edged rounded pellets are contained within the cushion. An outer covering of material covers the cushion and has a bottom surface. Attachment means secure the cushion and the outer covering in place on the armrest with the bottom surface of the outer covering in juxtaposition with the upper surface of the armrest.
- The invention still further provides a cushioned elbow support attachment for placement upon the upper surface of the armrest of a chair having an elongated sack-like cushion made of material having elastic properties and a plurality of smooth edged rounded pellets contained within the cushion. The smooth edged rounded pellets being circular or non-circular (for example, oblong) in shape, may consist of any natural or synthetic material, namely, polypropylene or low density polyethylene (LDPE), sand, gel, beans, seeds, or any like material. The pellets may have a mid-point diameter of one-eighth of an inch and a length of three-sixteenths of an inch. An outer covering of material comprising a top piece and a bottom piece attached together at a side edge seam extending around said cushion covers the cushion. Spaced straps attached to the outer cover at the edge seam secure the cushion and the outer covering in place on the armrest with the bottom piece of the outer covering in juxtaposition with the upper surface of the armrest.

FIG. 1 is an exploded view showing the components of the support cushion and a first strap arrangement to attach it to the arms of a chair. The cushion is designated by thenumeral 1.Cushion 1 comprises atop piece 2 and abottom piece 3 which are joined together at their edges by sewing or other appropriate means to form a sack that is filled with a plurality of smooth edge rounded polypropylene or low density polyethylene (LDPE)pellets 4.Top piece 2 andbottom piece 3 are made of material having elastic properties, such as polyester, lycra, spandex, cotton, or any combination thereof. The polypropylene or low density polyethylene (LDPE)pellets 4, in combination with the expandable fabrictop piece 2 andbottom piece 3, provide a verypliable cushion 1 which molds to the shape of the armrest of the chair and to the user's arm, maximizing the stability ofcushion 1 and the comfort provided to the user. This arrangement is shown inFIG. 2 . Assembly of the cushion can be accomplished by attaching the edges oftop piece 2 andbottom piece 3 together at their edges except for a small filler opening, through whichpellets 4 are inserted prior to the opening being closed. Whilecushion 1 is shown in the drawings as being made withtop piece 2 andbottom piece 3 comprising equal halves, the proportions of the two can vary, for example, withtop piece 2 describing a larger portion ofcushion 1 thanbottom piece 3. Alternatively, the cushion can be made of a single piece of material attached together at its side edges, or can be formed as a one-piece sleeve with the ends closed by appropriate means such as sewing. In addition, the shape ofcushion 1 is not limited to that which is shown in the drawings. - Polypropylene or low density polyethylene (LDPE)
pellets 4 advantageously are somewhat oblong in shape, as is shown in an enlarged view inFIG. 13 . The ranges of dimensions are a mid-point diameter (D) of one-sixteenth to three-sixteenths of an inch and a length (L) of one-eighth to three-sixteenths of an inch. The preferred dimensions are a mid-point diameter (D) of one-eighth of an inch and a length (L) of three sixteenths of an inch. - As shown in
FIG. 3 , an outertop cover piece 6 and an outerbottom cover piece 7 can alternatively be installed about thecushion 1. Outertop cover piece 6 and outerbottom cover piece 7 also can be made of fabric having elastic properties, or can be of non-elastic fabrics such as nylon, denim or neoprene, which provide more protection forcushion 1 and can be covered by decorative patterns. The presence ofouter pieces cushion 1 to the armrests of chairs of varying types without compromising the integrity of the structure ofinner cushion 1. - Further, the outer cover comprised of outer
top cover piece 6 and outerbottom cover piece 7 may be openable so as to remove the inner cushion comprised oftop piece 2 andbottom piece 3. This feature allows the outer cover to be more easily washed once the inner cushion is removed. The outer covers 6 and 7 may be closeable by any means known in the art. Such means may include but are not limited to: zippers, buttons, snaps, hook and loop mechanisms, or any other mechanisms currently or later known. - The manners of attachment of the elbow support to the armrests of chairs, which are described below, apply to both the basic single layer embodiment of
cushion 1 that is shown inFIG. 2 , and the alternative two-layer construction shown inFIG. 3 . - A first manner of attaching the cushion is shown in detail in
FIG. 1 . This system comprises a pair ofstraps toe section 11 upon which is one of theelements 12 of a hook and loop fastening system, that is, the hooks or the loops, amid section 13, upon which is theother element 14 of a hook and loop fastening system, and anend section 15 which terminates in aloop 16 through which aring 17 is passed. As shown inFIG. 1 ,mid sections 13 andend sections 15 are attached to cushion 1 by sewing them into the seam connectingtop piece 2 andbottom piece 3 or, if so provided ofouter cover pieces FIG. 4 illustrates how thetoe section 11 of each strap is passed through itsrespective ring 17 and then doubled back to engage the hook and loop fastening system. InFIGS. 5 and 6 the elbow support attachment is shown installed upon the upper surface of thearmrest 20 of a desk chair by passingstraps armrests 20 and then securing them in place. Also, as shown inFIG. 1 , an additional piece of hook orloop fabric 21 can be attached to the side ofcushion 1 to secure long loose ends oftoe sections 11 ofstraps - Alternative embodiments of the strap construction are also within the scope of the invention. For example, a first strap section carrying the hook portions of a hook and loop fastening system can extend from one side of the cushion, to mate with a second strap section carrying the loop portion of the hook and loop fastening system. Another example is making
straps cushion 1 or through loops attached to the exterior surface ofbottom piece 3 or, in the case of the two layer construction described below, through outerbottom piece 7. Straps with common buckle fasteners also can be used, as can separate straps that encircle the cushion and the arm of the chair upon which it is placed. -
FIGS. 5 , 6, 8, 9, and 10 show the invention attached to a desk chair's armrest. As used herein, the term armrest can be broadly defined as a “secondary surface”. To that end, the present disclosure contemplates attaching thecushion 1 to any secondary surface. Such secondary surfaces may include: a shoulder strap, a mouse pad, a vehicle console or any other console, a keyboard tray, or any other surface where a user may benefit from applying the described cushion thereupon. -
FIG. 7 shows the elbow support attachment in the form having an outertop piece 6 and anouter bottom piece 7. Attached to outerbottom piece 7 is a strip offabric 22, which carries either the hook or theloop element 23 of a hook and loop fastening system. InFIG. 8 , theother element 24 of the hook and loop fastening system is provided on twostraps 25 which encirclearmrest 20. A similar system is shown inFIG. 9 , where a connectingstrap 26 attaches the twostraps 25 together. The system shown inFIG. 9 insures thatcushion 1 can be positioned in a variety of locations onarmrest 20. In both of these arrangements, the straps can be attached to the arm of the chair by their own hook and loop systems or, alternatively, can be held in place by gluing or adhesive tape. A third version of this system is shown inFIG. 10 , where asingle panel 25 or a plurality of panels carrying the mating hook or loop element is attached to the top ofarmrest 20 of the chair by gluing or adhesive tape, which attaches directly tostrip 22. - Another manner of attachment is by means of tension clamps. As shown in
FIG. 11 , atension clamp 30 has a pair of opposed upwardly facing spring-loaded clampingarms 31 and a pair of downwardly facing spring-loaded clampingarms 32. Upwardly facingarms 31 can directly engagecushion 1 or, as shown inFIG. 11 , can engage ahard base 33 that is placed beneathcushion 1, or the downwardly facing tension loaded clamping arms can be attached directly to a hard base, upon whichcushion 1 can be attached through any of the means described herein. This arrangement is particularly well suited to install the elbow support upon an armrest where structure inhibits the attachment of the aforementioned straps, such as those commonly found on stadium, theater, airline and other like seats. The arrangement shown inFIG. 12 utilizes a pair of downwardly facing tension-loaded clampingarms 34, which can be attached directly to cushion 1 by means such as sewing or passing through a loop.Clips -
FIG. 13 shows the use of smooth edge rounded polypropylene or low density polyethylene (LDPE) pellets in the size ranges set forth above contained in a sack of material which has elastic properties makes the inventive elbow support attachment very flexible, and therefore it can conform to a multitude of armrest shapes and sizes while still providing very comfortable elbow support for the user. The plurality of manners in which the elbow support can be attached allows it to be used with virtually any armrest style or shape. These factors also make the device easily installable and removable from the armrest upon which it has been placed. -
FIG. 14 shows a rigid adapter plate 35 which may serve as an interface between acushion 36 according to the invention and atubular armrest 37 of a chair 38 (not shown in its entirety). This situation may be encountered with wheelchairs, in portable folding chairs, and with other types of seating. The adapter plate 35 may present an upwardly facing surface which is considerably greater in width along its length than thearmrest 37. The length of thecushion 36 and its component parts will be understood to be that dimension aligned with the length of thearmrest 37. Illustratively, thearmrest 37 may be fabricated from tube stock of nominal diameter of one inch, whereas the adapter plate 35 may extend lateral reach along the armrest 37 to a lateral span of three or four inches. The three or four inch wide platform gives the cushion 36 a sufficiently wide rigid seat so as to enable thecushion 36 to present a generally flat, planar surface for receiving the forearm of the user when the adapter plate 35 is installed to thearmrest 37. In the installed condition, the adapter plate 35 would abut thearmrest 37 and be secured thereto bybolts 43 and 45 This both increases comfort, since the forearm may be supported over a considerably greater surface area than would be the case if thecushion 36 were mounted directly to thetubular armrest 37, and also stabilizes thecushion 36 which may be difficult to mount to a relatively small, circular tube. Preferably, the upwardly facing surface of the adapter plate 35 bears hook and loop fastening material 40 which releasably mates with corresponding hook andloop material 39 disposed on the underside of thecushion 36. The hook andloop fastening materials 39, 40 serve as attachment elements disposed to releasably engage thecushion 36. - The
cushion 36 may comprise flexible wings 42 (one is concealed from view inFIG. 14 ) which project laterally from the body 44 of thecushion 36, the wings 42 extending along most of the length of thecushion 36. The arrangement providing wings 42 may include two separate wings 42 located on opposed sides of thecushion 36, or alternatively, may comprise a single panel of flexible material such as a woven or non-woven fabric, elastomeric sheet, or other flexible material which is fastened to the underside of thecushion 36, as is depicted inFIG. 14 . The hook andloop material 39 may be disposed on the underside of the wings 42. In the absence of discrete wings 42, the hook andloop material 39 could be disposed on the underside of the cover 52 of thecushion 36, or of thecushion 36 itself in the absence of the cover 52. - The wing or wings 42 provide lateral support for the cushion and help to maintain the position of the cushion upon the armrest. It is contemplated by the inventor that the wing 42 structure shown in
FIG. 14 , and as described fully above, would have the same benefit when used with the cushion shown inFIG. 7 . In the version shown inFIG. 7 , the wing 42 would attach to the outside surface of the cushion in the same manner as described forFIG. 14 . And in the case when only one wing is attached to the cushion, to better achieve the lateral support, thecushion 36 is positioned on the armrest so that the wing 42 contacts the inner surface of the armrest (toward the seat). In this position the cushion is able to withstand the lateral forces created when a user's arms move away from the body—as is typically the case in a seated position. When the cushion is utilized as shown inFIG. 14 , for example with a wheelchair, a pair of wings on opposite sides provides the desired enhanced lateral support. - The adapter plate 35 may be fastened to the armrest 37 by the
bolts 43, 45 which pass through holes 45, 46 formed in thearmrest 37. Thebolts 43, 45 may thread to holes 46, 47 formed in the adapter plate 35, or may thread to a raised boss (not shown) which may be formed integrally with the adapter plate 35 if desired. Thebolts 43, 45 may be sufficiently large and secure so as to hold the adapter plate 35 rigidly in place on the armrest 37 in a manner which opposes rocking and other disruptions under conditions of ordinary use. Thebolts 43, 45 and their corresponding threaded holes 46, 47 collectively comprise a fastener capable of securing the adapter plate 35 to thearmrest 37. - The armrest 37 may be deformed to better seat the heads of the
bolts 43, 45 by providing a non-arcuate surface. Deformation is indicated byvalleys 48, 50 formed in thearmrest 37. - Other than including accommodation of the adapter plate 35, the
cushion 36 may have features of thecushion 1 for example. Illustratively, thecushion 36 may have an outer cover 52 comprising a slide fastener 54 for removal. - While the present invention has been described in connection with what is considered a most practical and preferred embodiment, it is to be understood that it is not to be limited to the disclosed arrangement, but is intended to cover various arrangements which are included within the spirit and scope of the broadest possible interpretation of the appended claims so as to encompass all modifications and equivalent arrangements.
