Application June-16, 1949', serial No, 99,387 7 Claims,- (01. 155-9126) This invention relates to icldable chairs and more particularly to a new and improved high chair capable of being readily-and easil erected or collapsed and which is relatively compact when in folded condition.

Thehigh chair of'the present invention. comprises a rear frame, of which the rear legs of the chair form an integral part, a pair of angulated' side frame members pivotally secured to the rear frame, a portion of each comprising the front legs of the chair, and a. U-shaped seat frame pivotally carried'by the rear frame having members interengaging with the side frame mem bars for locking the'varlous elements of the chair in assembled position, and a frame pivotally mounted to the rearframe for'supporting a food tray. The various members constituting the elements of my chair are preferably of tubular construction thereby adding lightness, rigidity and pleasing appearance to the high chair, without sacrificing strength or durability.

It is among the objects of the present invention to provide a folding high chair in which the various elements comprising the chair areall pivotally mounted upon the rear frame of the chair and are collapsible relative thereto.

It is another object-of the invention to provide in a high chair a rear frame member; a; p of side frame members pivoted thereto, and a seat pivoted to the back frame and engageable with the side frame, members for locking the various elements in assembled relation;

A further objectof this invention is to provide a high chair of tubular construction embodying a rear frame member and aplurality of chair elements pivoted thereto, and anchorage for securing and rigidly holding the. movable elements in assembled relation: with respect to the. rear frame member.

- -A still further object of the invention is to provide a foldablehighv chair which. is simple. in design, economical to manufacture and which may be erected and collapsed with ease, and when assembled has all the characteristics, of a rigid construction.

These and other objects andadvantageous features of the invention not. at this time more particularly pointed out, will become more apparent as the nature of the invention is better understood vfrom the following detailed description taken in conjunction with the accompanying drawings, wherein like reference characters denote corresponding parts, and wherein:

Figure 11 is a sectional detail taken on theline I l--| I of Figure 10.

With reference to the accompanying drawings and particularly Figures 1, 2 and 3 thereof, there is illustrated a foldinghigh chair embodying the teachings of the present invention and including arear frame In; having a U-shaped portion II and depending tubular members l3 which are flared outwardly and rearwardly to define the rear legs H of the chair. The members I3 are secured to the U-shaped portion II by means of hinge pins l2 (see Figure 7). Encircllng the hinge pins [2 are rotatable sleeves I5, the purpose of which will be hereinafter described.

A back rest l6 may be secured to the tubular U-shaped portion ll of the rear frame in any suitable manner, as by means of fasteners I! (see Figure 6) extending through the tube into the rear panel of the back rest It.

Theseat [8 of the chair is of; padded construction and is suitably mounted upon a U-shaped tubular frame [9, the outer free ends of which are pivotally secured to the rear frame In as at 20 by means of pivot pins extending therethrough. Secured to thelower surface of the seat I8 adjacent to the forward end thereof is a hinge member 2| having a plurality of openings 2 la in the free portion thereof. The opening 21 are adapted to receive a stud 2|]; extending outwardlyfrom the end; of a foot rest 12 which in turn. is supported, from. the lower suriaocof; he

the front of the rear frame.

seat l8 by hook and eye elements 23. The structure thus provided serves to support the foot rest in various adjusted positions suitable for the child using the chair. Extending outwardly from the sides of the U-shaped frame l9 adjacent the forward end thereof are headed pins 24, the purpose of which will be hereinafter described.

With reference to Figure 2, there is best illustrated the side frames of the chair, which comprise an angular tubular member 25, the lower portion of which is flared forwardly and outwardly to define the front legs 26 of the chair. The free end of the horizontal portion of the member 25 is secured to the sleeve l in, any suit able manner, as by means of welding, brazing or the like. The side frames are provided with panels 25a to complete the chair. The tubular members 25 are provided with opposed inwardly facing keyhole slots 28 which, when the seat frame is dropped in horizontal position, are adapted to receive the head pins 24 and thereby lock the elements-of the chair in assembled position.

Pivotally mounted on the rear frame I0 is a U-shaped food tray holder frame 29 which is made in the usual shape and forms a band of encirclement for the protection of the chair occupant when the frame is lowered to its operative position. The sides of the frame 29 lie on the outside of the horizontal portions of the side frame members 25 and'serve to press the side rails inwardly, providing thereby normal pressure for holding the side frame members in rigid position."

A food tray 30 is slidably mounted upon the frame'29 (see Figures and 11). Secured to the side of the frame 29 is a channel shaped bracket 3|, which is adapted to be engaged by a complementary shaped bracket 32 secured to the lower surface of the food tray 30; Suitable apertures 34 are provided in the channel of the bracket 3| and are adapted to be engaged by spring pressed pins 33 carried by the bracket member 32 for securing the food tray in relative positions upon the frame 29.

With reference to Figures 2 and 3, the foldable high chair of my invention is collapsed or folded in the following manner: the food tray frame 29 is pivoted about into a vertical position above the rear 'frame as illustrated in Figure 2, the seat frame I9 is raised slightly to bring the heads of the pins 23 into alignment with the enlarged portions of the keyhole slots 28 at which point the side frame members 25 are moved outwardly to disengage thesame, the seat frame is then dropped to the position shOWn in Figure 2 between the rear legs M, the side frames 25 are folded against the back of the rear frame [0 and the food tray frame is dropped against In collapsed position the elements of the chair are positioned as shown in Figure 3.
