Patented June 22, 1954 UNITED STATES ATENT OFFICE 5 Claims.

My invention relates to an improvement in a fender and tray support device as an accessory for wheel. chairs. An object of the invention is to provide a device of the kind mentioned that may be attached to any standard wheel chair and will provide a shield or covering for the upper portion of the front side-wheels such that a woman sitting in the chair may work on sewing material, a part of which may fall over the wheel and if it were not for my improved fender device the sewing material would rest on or rub against the tire of the wheel and become soiled therefrom.

A further object of the invention is to provide a device of the kind mentioned in which a tray and supporting means therefor is provided. The tray may be a small tray that would be supported at either side of the chair or it may be a large tray that would reach across the front of the chair.

A still further object of the invention is to provide a device of the kind mentioned that is simple and sturdy in construction, one that is neat in appearance and easy and simple to attach to the chair and one that is inexpensive to make and buy. These and other objects will be more fully explained as this description progresses.

And now referring to the accompanying drawings in which similar numerals of reference designate the same parts throughout the several figures of the drawings;

In the drawings is shown a wheel chair having a wood seat frame element [5 as shown in Figures 1, 2, 3 and 4, or a tubular seat support frame 45a as shown in Figures 5, '7, 8, 9, l0 and 11. The seat l5 or [5a and the balance of the chair structure is supported on supporting and drive wheels I6 and Mia as shown in Figures 1, 2 and 3, or as shown at 161) and IE0 in Figure 5; and each of said Wheels are provided with a circular hand grip element H that are rigidly supported in an outwardly spaced position from their respective wheel l6, lfia, I612, or I50 and being concentric therewith, on supporting brackets or hangers 18.

My invention consists of a fender element F that has a side wall IS, the outer edge of which is arcuate and is rolled or turned outwardly as shown at 26 to cover and fit around the upper portion of its respective support or drive wheel I6, lBa, I6b or I60. The extreme edge of the out turned fender portion 20 is folded as shown at 2| to provide a smooth edge and double thickness of material to lend strength to the fender and to prevent cracking or breaking of the fender edge.

Each fender is supported on a forward standard S and a rear bracket R.

The forward standard consists of a vertically positioned leg element 21 on the lower portion of which is integrally formed a pair of laterally extending and spaced apart clamp legs 22 and 23 and between which the seat frame element 3 i5 is positioned and the clamp leg 22 rests thereon. The lower clamp leg 23 has an elongated slot 24 longitudinally positioned therein and bounded on each side by lip like elements 25 and 2% that are bounded by upwardly extending side wall portions 2? and 28 between which is slidably positioned a nut 29 that is slidably supported on the lip elements 25 and 25. A winged screw 36 is passed upwardly through the slot 24 and is threaded through the nut 29 and the upper end of the screw 30 is provided with a clamp foot 3| that is adapted to engage and press against the under side of the seat frame [5 as the screw as is screwed upwardly so as to bind and rigidly hold the support bracket S on s the chair seat element E5. The upper portion of the supporting leg 2| has an inwardly directed curved portion 32 and then continues on upwardly as a support leg Zia for purposes that will later be made obvious.

Each fender is provided with a second or rear support bracket R that comprises a vertically positioned supporting leg element 33 and which is provided with a pair of laterally extending and spaced apart clamp legs 34 and 35 that are integrally formed on the vertical leg 33, and between which the rear portion of the seat frame i5 is positioned and on which the upper clamp leg 35 rests. The lower clamp leg element 35 has an elongated slot 36 longitudinally positioned therein. The clamp leg 35 is constructed the same as shown and described in Fig. 12, including the nut 29, winged screw 30 and clamp foot 3 l In both vertical supporting legs 33 and 2| of the forward standard S and rear supporting leg 33 of the bracket R is a pair of elongated slots 3? and 38 therethrough.

The side wall E9 of the fender F has three pairs of holes 39 and 13, ll and 42, and t3 and 4 5. The holes of each pair of holes are positioned, one vertically above the other, and the pair of holes 39 and it are positioned midway between the ends of the fender and the pairs of holes 4| and and 43 and it so that bolts 45 and 45 may be passed through the holes 353 and 4.0 in the fender wall it and through the elongated slots 3? and 38, whereupon nuts M and E8 may be threaded on the bolts A5 and 56 to hold the fender wall is on the supporting leg 21. Similarly bolts 9 and 58 are passed through the holes l! and 32 in the fender wall l9 and also through the elongated slots 3? and 38 in the supporting leg 33 of the bracket R and nuts 5| and 52 are threaded on the bolts M and to also hold the fender plate l9 on the vertical supporting leg of the bracket R.

The fender brackets having thus been assembled the brackets S and B, may be slid along the chair seat frame element 5 to properly position the fender F longitudinally and equally over the supporting wheel whereupon the wing screws 39 in both brackets S and R may be screwed upwardly so that the clamp foot 3! on each screw 36 bears against the seat frame element l5 to rigidly bind and hold the supporting brackets S and R on the seat element l5.

Before tightening the screws 30 the supporting brackets S and R may also be moved toward or away from the seat frame element l5 to properly position the fender F over the drive wheel It. The fender having thus far been adjusted, may then be raised or lowered so that the rolled portion 28 will have the desired clearance above the wheel i6 whereupon the nuts 41, d8, 5l and 52 may be turned on their respective bolts to rigidly 4 bind and hold the fender plate l9 and fender F in its adjusted position relative to the wheel [6 and chair seat l5.

The relative positions of the pairs of holes H and 42, and 43 and 44 to the pair of holes 39 and 40 makes the fender F universal for use on either side of the chair which eliminates the problem of making right and left fenders, therefore a fender and supports therefor may be mounted, one on each side of the chair in the same manner above described and shown in Fig. 2.

The device is provided with a tray support element T, that is in the shape of an inverted L and the lower end of the vertical leg is provided with a'socket that is adapted to slip over and receive the upper end 21a of the supporting leg 2| of the front bracket S. The horizontal leg 54 of the tray support element T has a vertically positioned hole 55 therethrough in which a tray support pin 56 is receivable for purposes of supporting a tray structure 51 at the side of the chair and over the fender F.

The pin 56 and the hole 55 are tapered so that the pin 56 will fit solidly in the hole 55 and will not allow the tray 5! to tip, although it can be turned in a horizontal plane to fit the convenience of the person using the chair. 1

If desired, two tray support brackets T may be employed and positioned one on each front fender support element S and the horizontal legs of the bracket T turned either in or out as indicated in Fig. 5 and a long tray 51a having a pin such as 55 on either end thereof may be inserted in the two supporting brackets T to support and hold the tray 51a. Either tray may be moved from its supporting brackets merely by lifting the tray to demount it from its supporting brackets.

Some wheel chairs have a metal tubular frame such as that shown in Figs. 5, 7, 8, 9, 10 and 11. In these views the supporting brackets S and R are pivotally supported on one end of a link 58 and are adjustably held in position thereon by means of a bolt 59 and a wing nut 60. The other end of the link 58 is pivotally mounted at El on the upper side of a G clamp body 62, the opening of which is large enough that the seat frame tube I5a will pass therethrough and be seated in the upper curved portion of the C clamp body 62. The lower portion of the C clamp body 62 is provided with a wing screw 63 that is threaded therethrough and is provided with a clamp foot 64 that is curved to fit against the tubular seat frame element l5a and is swivelly mounted on the upper end of the wing screw 63.

The fender plate i9 is attached to its respective bracket support element the same as previously described. The adjustment of the C clamp 62 having been made, the wing screw 63 may be screwed upwardly until the clamp foot 64 engages and binds against the tubular seat frame I50. to rigidly hold its respective fender support element S or R in its adjusted position.

While the device as shown and described is probably the preferred form of the device, it is to be understood that such modifications of the device may be employed as lie within the scope of the appended claims without departing from the spirit and intention of the invention.
