Referring in detail to the drawings, the chairA generally comprises a pair of frames A and B, composed of strip or channel metal, or any other suitable material.

The frame A is bent into substantially inverted U-form so as to provide a back portion i and integral front leg portions 2. The free ends of` each of the front leg portions 2 are bent outwardly, downwardly, and inwardly as at 3, and the outwardly and inwardly bent portions are provided with vertically alined openings (not shown).

The bent portions 3 of the front legs in effect, provide inwardly facing opposed recesses or sockets 4, each to receive one end of a transversely extending brace bar y5. 'The bar 5 is also provided adjacent each of its ends with an opening to register with the vertically alined openings formed through each of the bent portions 3 of the front legs so vas to provide a bearing. Rollers or other anti-friction members 6 are provided, each having a pintle 'l adapted to be passed vertically through each set of alined openings in each bent portion 3 and the adjacent enci of the bar 5, and secured by a nut or any other suitable fastener 8. This arrangement connects and 2braces the lower end portions of the front legs Connecting and supported by the .front legs intermediate -the ends of the latter is a transversely extending foot rest 9 having each of its ends provided with a right angle bracket i0.

Each of the brackets Il) has its free end formed with an opening to receive a detachable bolt Il which passes therethrough and through one of the spaced openings i2 formed in the front legs, whereby the foot rest may be adjusted to suit the convenience of the occupant of the chair.

The metal frame B is also bent into substantially inverted U form, so that the sides thereof provide rear legs I3. The bight portion of the frame B is bent at an angle to the leg portions thereof so as to provide a substantially horizontal tray support I l. The frames A and B are pivotally connected together by rivets I5.

In order to limit hinged movement of the frames A and B away from each other and to hold the frames in their operative position.- each of their adjacent side portions are connected together by folding braces I6, the latter being con- .structed so as to break ,in an upward direction.

The rear ends of the braces I6 are hingedly connected to the back portion of frame A by rivets while their front ends are connected to the frame Bo by a transversely extending detachable brace rod I1, which latter also forms the inner or rear side of the tray portion I4. Each of the lower free ends of the rear legs I3 are curved outwardly and downwardly as at I3 and provided with alined openings to receive a transversely extending axle I8 to which rollers I9 are connected, and which axle also serves to brace and to prevent spreading movement of the rear legs.

The detachable unitary fabric structure, the several parts of which are disclosed in Figs. 6 to 10 inclusive and which forms the back, seat, and tray of the chair, comprises a one-piece main blank C divided into a back portion 20, a seat portion 2 I, and a tray portion 22. In the description of the yseveral parts of the unitary fabric structure and the method of connecting same to each other, like reference characters in Figs. 6 to 10, indicate like parts.

Secured to the rear face of the back portion 2i) along the line of stitching c, indicated in dotted lines, in Figs. 6 and 9 is a part 23, which together with the back portion 20 provides a downwardly facing pocket to receive the bight portion of the frame A. The line of stitching c extends from notches a to b as indicated in Figs. 6 and 9.

The part 24 indicated in Fig. 8 forms the side of the chair to the right of the occupant and is connected along its rear edge to that portion of the back 2U which extends from notch a to point c by a line of stitching d, while the bottom edge of part 24 is connected to the right edge of the seat portion 2I by a line of stitching e extending from points c to f in each of Figs. 6 and 8.

The seat portion 2| is connected to the tray portion 22 by a strip 25 having cut-outs 26- on either side thereof to receive the legs of theyoccupant when the chair is in use.

The front edge of the part 2l is connected to the side of strip 25 by a line of stitching g extending from points h to i in each of the Figs. 6 and 8. The tray portion 22 is then folded downwardly along line :i until line 1c registers with line l, whereupon the fabric is stitched along the meeting lines k and l so as to provide an open ended transverse sleeve 21 as shown in Figs. 1 and 5.

The flap m, of part 2l is folded outwardly and downwardly along fold line n to provide a valance which is connected along its rear edge by stitching o between points a and p to the free portion q of the part 23.

The upstanding front and sides of the tray 22 I are formed by the part 28 folded along' line r which further provides an overhanging valance s. The part 28 is secured along its bottom edge to the front and side edges of the tray portion 22 by a line of stitching t extending from points u to v, while substantially the lower one-half of the rear edge is secured to the front side of the sleeve 21 and substantially its upper one-half to the forward edge of valance m oi part 24.-

The connection of part 29, shown in Fig. 7, which is the left side of the chair when facing forwardly, is accomplished in a manner similar to the description for connecting the right side for preventing the accidental displacement of the latter.

In the operation of setting up the chair and attaching the unitary fabric supporting structure thereto, the frames A and B are moved away from each other about their pivots I5. The unitary fabric structure for supporting the infant, and which includes the back, seat, and tray portions, is then placed over the frames so that the bight portion of frame A is received in the downwardly facing pocket of said back portion, while the seat and tray portions are disposed over the braces I6 and upper portions of frame B so as to be supported by and to conceal these parts.

' The transverse brace rod I1 is partially removed and then replaced so as to extend through the sleeve 2l, to thereby prevent removal of the fabric supporting structure from the frames in an upward direction upon removal of an infant from the chair. As a further aid in securing the tray portion of the bight portion of frame B, the cords or tapes 3f! are provided for use in the manner indicated in the drawings.

To collapse the chairl for storage or transporting purposes, it is merely necessary to break the braces in an upward direction as shown in Fig. 4.

In order to remove the unitary fabric supporting structure for laundering or replacement, the cords 30 are unfastened and the transverse brace rod I1 is partially Withdrawn so that the sleeve 21 may be slipped therefrom, thereby permitting the entire structure to be removed in an upward direction.

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.
