An additional feature of this invention is the provision of means for adjusting the length of the understructure to accommodate various sized chairs and invalids.
A further feature is the provision of means for pivoting the tray and supporting understructure about a vertical rear axis to permit the user to conveniently mount or leave the chair without removing the tray.
FIGURE 1 is a perspective view of the present invention shown secured to a chair,
FIGURE 2 is a bottom plan view of the invention shown per se,
FIGURE 3 is an enlarged view taken on line 33 of FIGURE 2,
FIGURE 4 is a bottom plan view of the structure shown in FIGURE 3, and
FIGURE 5 is an enlarged cross sectional view taken on line 5-5 of FIGURE 2.
Referring now to the drawing in detail, the reference numeral represents an improved tray attachable to a chair of an invalid according to the present invention wherein there is a fiat tray member 11 mounted upon an understructure 12 that is removably secured in a frame 13 that is fastened to a support structure 14.
The understructure 12 includes a front mount 15 and rear mount 16. The front mount is comprised of a bracket 17 secured by screws 18 to the underside 19 of the tray, the bracket holding a transverse bar 20. The rear mount 16 comprises a channel 21 secured by screws 22 to the tray underside 19, a sliding rod 23 on each end of the channel and secured in selective position thereto by thumb screws 24, each rod 23 supporting a slidable bar 25 having a hook 26 at its end for attachment to a swivel, each bar being normally urged into retracted position by a tension spring 27, and each rod 23 having a hook 28 at its end for clamping around an L-shaped channel 29 that forms a part of the frame 13.
The frame channel 29 received in one end thereof an end of the bar 20. A wing nut 30 secures the two together. The opposite end of the channel 29 receives an end of a rod 31 having a series of equally spaced openings 32 therein which are selectively engageable by a spring biased lever lock 33 mounted upon the channel 29. The rod 31 rice which forms a part of the frame 13 has an opposite end receivable within a channel 34 that forms a part of a hinge 35; there being a ball pin fastener 36 for securing the rod 31 thereto. The hinge member includes a transverse channel 37 into which one end of a transverse support bar 38 is received. The bar 38 is secured by screws 39 or the like to the rear side 40 of a back rest 41 of a chair v42.
In operative use the tray assembly 10 rests upon the arms 43 of the chair, and the tray may be upwardly tilted about the hinges35 so to permit a person to move into or out of the chair. The tray may be disconnected from the supporting structure or the frame by means of the above described various thumb screws and the lever lock on each L-shaped channel.
