CHAIR Filed April 24, 1935 v 2 Sheets-Sheet l H. F. DAVIS CHAIR Filed April 24, 1935 2 Sheets-Sheet 2 Patented Dec. 3, 1935 UNITED STATES PATENT OFFICE CHAIR Harold Frank Davis, Keene, N. H. Application April 24, 1935, Serial No. 18,047

' 6 Claims. (01. 155-127) The present invention relates to new and useful improvements in chairs of the type having a tray associated therewith, and more particularly to a chair of the above type wherein the 'tray is pivotally mounted thereon for horizontal swinging movement.

An object of the invention is to provide, in a chair of the above type, an all-metal tray assembly having a, depending pivot post and a latching device welded thereto at opposite sides thereof for cooperation with the arms of the chair.

A further object of the invention is to provide, in a chair of the above type, an improved latching device which is welded to the tray at one side thereof.

The above and other objects of the invention will in part be obvious and will be hereinafter more fully described.

Referring to the drawings:

Fig. 1 is a prospective view of the assembled chair and tray.

Fig. 2 is a sectional view taken along line 22 of'Fig. 1 showing the improved locking device.

Fig. 3 is a side elevation of Fig. 2.

Fig. 4 is a greatly enlarged plan view of the improved locking device.

Fig. 5 is an enlarged plan view showing the details of the pivot for the tray.

Fig. 6 is a sectional view taken along line 6--6 of Fig. 5.

Fig. 7 is a plan view in section taken along line 1-7 of Fig. 6.

In Fig. 1 of the accompanying drawings, the

. .chair I8 is illustrated as being of the highchair type, but it is to be clearly understood that the tray assembly may be used with chairs of other types. The tray II is preferably made of sheet metal and has an outwardly extending peripheral edge which is rolled or turned inwardly as at I2 so that no sharp edges will be encountered. The tray is pivotally mounted as at A on an arm I3, this arm having an enlarged wing portion I3a which aids in supporting the tray when it is swung .to an open position. A latching device B is welded or otherwise suitably secured to the opposite edge of the tray and is adapted to cooperate with a keeper C on the other arm I4 of the chair for looking the tray across the front of the chair.

The pivotal connection between the tray and the arm I3 will now be described, reference being made particularly to Figs. 5 to '7. The arm I3 has a properly shaped opening therethrough into which is pressed a metal bushing I5. This bush- .ing is provided with a pair of diametrically opposed slots or openings I6 and with a pair of diametrically opposed ears I7. The ears I I extend outwardly from the body portion of the bushing and rest upon the upper face of the arm I3 so as to prevent the bushing from falling therethrough. A depending pivot member or post 5 I8 is secured to the underside of the tray II. This post I8 is provided with outwardly extending ears I9 which are secured by spot welding or the like to the face of the tray I I. The post I8 is provided with a pin 20, the ends of which extend beyond the periphery of the post I8 and are inserted into the diametrically opposed slots IS in the bushing I5. When in this position, the tray may be pushed down so that the pin 20 is disposed at a point below the bottom edge of the bushing I5 and the underside of the arm I3, as shown in Fig. 6. The tray may then be turned about its pivot point to the position shown in Fig. 1. It is to be noted that the position of the bushing I5 in the arm I3 and the position of the pin 20 in the post I8 are such that when the tray is in its normal closed position across the arms of the chair and its normal open position at approximately ninety degrees from its closed position, the ends of the pin are out of line with the slots I6 in the bushing I5 so that the tray must be turned through an angle of well over ninety degrees from its closed position before it can be removed from the arm of the chair.

Referring more in detail at this time to Figs. 2 to 4, the improved locking device for holding the tray in position across the arms I3 and I4 will now be described. The keeper C is preferably in the form of an angle plate having a horizontal portion 2| which fits over a portion of the upper face of the arm I 4- and a depending side portion 22 which fits next to the outer edge of the arm I4. The keeper C may of course be made up in a plurality of sections if sodesired. As shown in Fig. 4, the outer side edge of the arm I4 is slightly cut away so as to provide clearance for the latching device B as the tray is swung to and away from its locked position. The angle plate is secured to the arm I4 by screws 23 or the like. The depending side portion 22 of the angle plate has a portion thereof cut and formed to provide a keeper 24 which extends outwardly from the arm I4. The horizontal portion H of the angle plate has an upwardly bent rear portion 25 which serves as a stop against which the rear edge of the tray I I abuts when in locked position.

The latching device B includes a guide member 26 which has a laterally extending upper edge or flange 21 which is welded to the underside of the inwardly rolled edge I2 of the tray II. As

2 shown in the accompanying drawings, the laterally extending edge 21 is provided with an offset or slightly depressed central portion 28. The guide member 26 is provided with a cut-out portion 29 in the side thereof below the depressed portion 28, the bottom edges of the guide member being joined by an offset portion 36 which greatly strengthens the same. As shown in Fig. 2, the lower portion of the guide member 26 is curved outwardly as at M in order that it will clear the keeper 24 as the tray moved about its pivot point. A spring latch 32has a portion thereof tightly fitting between the guide the edge of the tray H. the latch 32 is bent outwardly to extend between the inwardly rolled edge of the depressed portion 23 is embossed to provide an irregular raised surface 34, and the outwardly bent portion 33 of the latch 32 is cut out to provide 32 will ride over the inclined surface of the keeper.

2d and will ultimately spring down behind the edge of the keeper as shown in Fig. 2, when the tray has reached the limit of its inward movement by engagement with the stop 25. As has been heretofore pointed out, the outwardly curved portion St on the guide 2% permits the closing of the tray without interfering with the keeper. When it is desired to release the tray from its locked position, it is merely necessary to grasp the end portion 32a of the latch 32 and pull the same outwardly beyond the edge of the keeper 2 so that the tray may be swung outwardly. The of:- set portion 38 at the bottom edge of the guide 2% permits this movement of the latch 32 within the cut-out portion 2e.

From the foregoing description, it will be ap parent that the present invention affords a comtray includes a'pivot V pact all-metal tray. The post welded thereto which fits within a bushing in one arm of the chair for providing a pivotal connection about which the tray may be swung horizontally. There is also provided a latching device which is rigidly secured by welding to the opposite edge of the tray and which cooperates with a keeper mounted on the other arm of the chair.

It is to be clearly understood that minor changes in the details of the construction and arrangement of parts may be made without departing from the scope of the invention as set forth in the appended claims.
