April 25, 1950 B. J. GREENBAUM HIGH CHAIR TRAY Filed Jan. 22, 1947 lurllllllllllll| llilnnlnlnlfllllllvlll:

INVENTOR. JGYreencz/um atented Apr. 25, 1950 L lTED STATES This invention relates to high chairs and more particularly to high chair trays. An object of the invention is to provide a tray which will be secure and firm but which nevertheless may be easily detached with one hand so that the child may be guided or held with the other hand. A further object of the invention is to provide a tray which may be selectively lifted over the head of the child and allowed to rest against the back of the chair or withdrawn directly and removed. A still further object is to provide a tray with positive gripping means and so constructed that there is no possibility of the tray coming loose when a childs weight is pressed against it. A

still further object of my invention is to provide a tray which is adjustable so that it may be brought closer or farther away from the back to accommodate itself` to the size of the child. Other objects and advantages of my improved tray will be apparent from the accompanying 1 drawings and description.

In the accompanying drawings:

Fig. 1 is an inverted View of my improved tray showing the operating mechanism in a closed position fastened to the chair.

Fig. 2 is a partial view similar to Fig. 1 but with gripping means open for removal of the tray from the chair.

Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 1 with the chair shown in outline for clarity.

Fig. 4 is a detailed enlargement showing the operation of the clamping means.

Fig. 5 is a cross-sectional view taken on the line 5--5 of Fig. 4.

Fig. 6 is a view showing a combined tray holder and arrester which is adapted to be used as a guard and tray holder.

Referring more particularly to the drawings, while I have shown a chair Ill of a particular type, it will be understood that my tray may be applied to practically any type or configuration of chair. Similarly, while I have shown a tray l5 of a definite configuration and shape this is of secondary importance and a square tray or oblong tray could be used as well. Fastened to the tray l5 is a plate I6 which may be screwed by means of the screws I1 or otherwise fastened to the tray. The plate IB has an upturned ange i8 which serves a dual purpose. through an opening in the flange i8 is an arm i9 carrying the operating handle 20. Fastened to the arm I9 at 2l is a spring 22 having its other end 23 engaging the flange I8. The arm I9 -is fastened at its inner end to a bar 25 which is pro- Extending r vided at either end with studs 2S extending through slots 2l in the plate i6. The slots 21 are substantially parallel to each other and in the same general plane as the arm i9. The arm I9 is also provided with a stud 28 which rides in the slot 2!! in the plate it and engages the bar 25 thus limiting the movement of the bar 25. Pivotally mounted on the plate I'E are arms 3B pivoted at 3|. The arms 3@ are provided with gripping members 32 of channel formation and also are provided `with slots 33 through which the studs 26 extend. The slots 33 are at an angle extending inwardly with relation to the slots 2l* so that when the operating handle 2!) is pulled toward the front of the tray the studs 2t riding in the slots 2'! and 33 will cause the arm 3l] to pivot en the point 3| outwardly and away from the center line of the tray. The inner portions of the gripping members 32 are provided with teeth 35. The chair is provided with a pair of brackets 4U the outer surface of which are serrated to form a plurality of teeth lil adapted to mesh with and engage the teeth 35 on the gripping members 32. In operation the tray is placed on the chair by the simple operation of pulling the operating handle 20 toward the front of the tray and sliding the gripping members 32 over the brackets [it until the desired position is reached, at which time the handle is released. It will be noted that there are a number of teeth 4| to allow the tray to be positioned in a number of selective points. When it is desired to remove the tray it is only necessary to exert pressure on the operating handle and to pull the tray away from the chair. As shown in Fig. 5, I provide a combined tray holder and guard 45 which is pivoted at 4B to the back of the chair. This is provided with teeth il similar to the teeth 4I and with a bar 48. extending across the front of the chair. This can be used as shown in Fig. 6 simply as a guard to prevent the child from falling out of the chair and can 'be swung over the back of the chair when it is desired to fasten the tray rigidly to the brackets lill or may be used as a tray holder with the gripping members 32 gripping the teeth fil. With this alternative the entire tray may be swung over the back of the chair and allowed to remain on the tray holder and guard 45. It will be appreciated that any modiiication of my invention can be made such as the use of a leaf spring positioned against the fiange I8 and against the bar 25 without departing from the spirit and basic concept of my invention. It will also 'be appreciated that the plate I6 may be built into the tray in numerous ways but that regardless of how it is positioned it provides a simple method of operation.

I claim:

1. The combination with a chair, of fixtures fastened to each side thereof, a tray, arms pivotally mounted on said tray, spring means for normally tensioning said arms towards each other thus engaging said xtures, and a handle operatively connected to said arms to force them in the opposite direction,

2. The combination with a chair, of serrated fixtures fastened to each side thereof, a tray, serrated arms pivotalh7 mounted on said tray, spring means for normally tensioning said towards each other thus engaging said fixtures, and a handle operatively connected to said arms to force them in the opposite. direction.

3. The combination with a chair, of serrated fixtures fastened to each side thereof, a tray, arms pivotally mounted on said tray, each of saidarms having a channel serrated'on the inner `su face thereof, spring means for normally tensioning said-arms towards each other thus causing the engagement of the said serrated channel .of-,each arm with the serrated portion of vixtnre, and a handle operatively connected ta .Said arms to force them in the opposite direction.

4. TheV combination with a chair, of a tray, iix- -tures fastened to said chair, means for detaehably-fastening said tray to said fixtures, includ ing a plate having parallelslots .at each end` :in arm VVvotarlly mounted on each end of said plate hen/.ng slots therein extendingV at an angle to said plate slots,v gripping means on the end portions of said arms, a bar with a stud on each `s rietportion of said oar extending through the aferernentio ned plate slot and arm slot, and an operating handle engaging said 'bar to nieve it rela-tion to said plate causing said arms to pivot on said plateengaging and disengaging said nxtures.

5. Ina chair tray, a pair of s rrated arms, spring means-tensioning said towards other, a bar engaging said arms by pin-and-slot cennections, andan operating handle attached to said bar the movement of which againstA the urging of saidl spring means causes said bar to ineve'said varms, away from eachV other.

G, The combination with a chair, of serrated natures mounted on said Chair so as to pivot over back thereof, a tray, serrated arms pvotally .mounted on said tray, .Spring means for mm1-,ally tensio f said arms twards each other thus engaging said xtures, anda handleeperatively connected to said arms to force them in the opposite direction.
