HIGH CHAIR TRAY SLIDE Filed March 26, 145

BY i @fiona Patented Apr. 20, 1948 UNITED STATES PATENT OFFICE HIGH CHAIR TRAY SLIDE Edwin W. North and Roy A. Stone, Rockford, Ill.,

assignors to National Lock Company, Rock- I for-i111., a corporation of Delaware Application March 26, 1945, Serial No. 584,796 s claims. (c1. 155-127) port a childs food and toys, but also to hold the child from falling or sliding out or off of the chair.

One of the purposes of our present invention is to provide equipment for detachably mounting a tray upon the arms of a chair so that it may be disconnected and removed from the chair, thus freeing the child for removal from the chair.

In addition `to the general purpose of rendering the tray detachable, our invention is designed to provide for adjustment of the tray so that it may be locked in position at varying distances from the back of the vchair to accommodate children of different sizes.

Furthermore, the locking means is automatic in its operation of locking, brut is manually releasable and so constructed that it cannot be readily released by the child and so that it affords no opportunity for catching or injuring the chiids fingers or hands.

Another feature of our invention is the provision of la stop or abutment which limits the movement of the tray toward the back of the chair, so that it cannot be accidentally pulled or pushed far enough back to squeeze the child or make it uncomfortable..

Other advantageous features of our invention will be readily appreciated as the same becomes better understood by reference to the following description when considered in connection with the accompanying drawing.

Referring to the drawing,

Fig. 1 is a fragmentary side elevation of a high chair embodying our invention;

Fig. 2 is a, fragmentary :planv view of the disclosure of Fig. l;

Fig. 3 is a vertical sectional view on the line 3 3 of Fig. v2;

Fig. 4 is a transverse sectional view on the line 4-4 of Fig. 3; and y Fig. 5 is a bottom View looking upwardly at Figs. 1 and 3.

Referring to the drawings more in detail, reference character 6 indicates generally a high chair of any preferred design provided with the parallel arms 1 adapted to serve as the support for a tray 8 proportioned to overlie the arms and shaped to conform to the body of a child when seated in the chair.

For the purpose of detachably and adjustably mounting the tray upon the arms of the chair, our invention contemplates the provision of equipment consisting of hardware, a portion of which is adapted to be mounted on the chair arms and another portion of which is adapted to be mount- `2 ed on the bottom of the tray, so that it will be slidalbly engaged with and connected to the portion mounted on the arms.

The arm portion of the equipment consists of a track formed of sheet metal providing a body 9 of channel shape consisting of an upper wall II, a vertical outerwall I2 and a bottom wall I3 from the inner edge of which depends a flange I4 adapted to lie against the vertical outer face of an arm 'I and be secured thereto by screws I5. Since the two track members, one for each arm, are identical except for being reversed and the parts cooperating therewith are also similarly identical, a detailed description of one only will suflice.

The forward end of the track body 9 is tapered, as indicated at IS, to receive the slide, and the rear end of the lower wall I3 is provided with a depending stop or abutment Il which limits the 'rearward movement of the tray toward the chair back. The lower wall I3 is also provided intermediate its ends with a plurality of spaced apart slots or openings I8 adapted to receive a latching detent, which will be later described.

The cooperating member of the equipment comprises a channel-shaped slide Iii consisting of an upper Wall 2i secured to the lower face of the tray 'I by a plurality oi screws 22, a vertical wall 23 and a bottom wall 24. These channel members are attached to the tray in such spaced relation as to receive and ride upon the track members 9 when the tray is slid onto the arms of the chair.

For the purpose of releasably latching the tray in adjusted position on the track members, an angle-shaped latch 25 is pivotally mounted on a pivot pin 26 upon the outer face of the vertical wall 23 of the slide. The rearward portion of this latch is inclined or sloped upwardly as indicated at 2l, terminating in an upwardly projecting detent 28 which extends through an opening 29 formed in the bottom Wall `24 of the slide. An expansion spring 3| interposed between the tail of the latching member and the bottom wall 2li of the slide biases the latching member in a clockwise direction, viewing Fig. 3, about its pivot so Vas to project the detent through any latching opening I8 with which it becomes aligned, thereby latching the slide against movement on the track.

It will be apparent, therefore, that when the tray is slid over the arms of the chair, the slides ride upon the tracks and, if the latches 25 are released, they will snap into the track openings I8, thereby locking the tray to the chair.

The latches are so shaped that they cannet be released or readily manipulated by the child, and by reason of their angle-shape no slot or opening is presented in which the childs lingers may become caught or injured,

The inclines I6 at the forward end of the tracks enable the slides to be engaged with the tracks without manipulation of the latches 25, since the inclines will force the latch detents 28 outwardly as the slides move backwardly upon the tracks. When the latches are held released, the

tray may be moved backwardly until the rear ends of the slides engage the stops or abutments Il Y on the tracks, whereby the rearward movement of the tray is limited. The slides may be Adiscon- Y nected from the tracks by pressing upwardly against the tails of the latches 25, thereby enabling the tray to be detached and removed from the chair.

The structural details illustrated and described may be varied within considerable limits without departing from the scope of our invention as dened in the following claims.

We claim:
