Claims.

hanging position.

, More particularly my invention comprises a chair that has a. frame with a pair of upstanding side members and a pair of seat supporting members slidably mounted on the upstanding members so that said seat supporting members can be moved from a position adjacent one end of the upstanding members for one of the positions of said chair to a, position adjacent the other end of said upstanding members for the other position of said chair.

Another important characteristic of my improved chair is that the back thereof is made of flexible material so that it will be in an extended position to support the back of the child occupying the chair in the floor supported position thereof and will be in a folded position under the seat when the chair is in a position in which it is supported from an automobile seat.

One of the principal features of my invention is the provision of cushioning means in the form of coil springs on the upstanding members that act as supporting means for the seat supporting members to provide a cushion mounting therefor, particularly in the position thereof on an automobile seat, enabling the child sitting in the chair to bounce up and down with the seat due to the action of said springs.

.Another important feature resides in the pro- Vision of means for adjusting the elevation of the seat when same is hung over the hack of an automobile seat or the like.

It is still another important purpose of my invention to provide a chair that can be folded up into a compact form for shipping purposes or for storing purposes, this being accomplished by providing a mounting for the seat whereby the seat can be swung adjacent one of the seat supporting members and the seat supporting members being swingable about the upstanding frame members so as to fold the seat and the seat supporting members into substantially the same plane as the upstanding frame members.

The flexible back supporting member is not only detachable from the seat to permit this, but is also detachable from the frame so that it can be removed and washed wheneverithis is desirable. The mounting for the flexible back supporting member on the seat is. preferably. ad-

" inclined toward the arm 2 justable so as to adjust the position of the flexible back supporting member relative to the seat and the tension thereon.

Other objects and advantages of my invention will appear as the description of the drawings proceeds. I desire to have it understood, however, that I do not intend to limit myself to the particular details shown defined in the claims.

In the drawings:

Fig. 1 is a perspective view of my improved or described, except as childs chair inthe position it assumes when supported on a floor or similar surface,

Fig. 2 is a similar view, showing thechair in the position it assumes when suspended or supported from an automobile seat or similar member, and

Fig. 3 is a fragmentary'vertical sectional View through the chair, taken on the line 3-3 of Fig. 2.

Referring in detail tothe drawings, my improved Chair comprises a frame that has a pair of parallel upstanding side members H), a transversely extending member I I, which may be provided with an outer covering I 2 of rubber or similar cushioning material. The upstanding frame members "l0 are provided with bends i3 therein of long radius and have supporting portions l4 extending from the ends thereof opposite those connected by the transverse member ll, obliquely extending portions 35 extending from the supporting portions I4, and a transverse frame portion 16 connecting the obliquely extending portions l5. A sleeve of rubber or similar cushioning material I? is, preferably, provided on the portions l4, l5 and 16 of the frame.

When the chair is in the position shown in Fig. 1 the supporting portions M are in engagement with the floor, the obliquely extending portions l5 extend upwardly away from the floor and the transversely extending portion 16 is spaced from the floor. When the chair is in the position shown in Fig. 2 the supporting portions M are in engagement with the top of the automobile seat and the portions [5 and I6 extend around the back of the seat, while the curved or bent portions I3 follow the curved contour of the forward upper portion of an automobile seat.

Mounted on the upstanding frame members III are substantially C-shaped auxiliary frame membars that serve as seat supporting members, said auxiliary frame members each having a pair of arms l8 and [9 connected b the upstanding portions 20. The arms l8 and I9 extendsubstantially in parallelism, the arms I8 being slightly l9 toward theends can be swung on the other set thereof that are remote from the connnecting portion 20, as will be obvious from Figs. 1 and 3. Accordingly when the eyes 2i on said arms I8 are in the position shown in Fig. 1 '(i. e., in engagement with the bends 22 connecting the portions H of the frame with the portions 10) the forward end portions of said arms I8 adjacent the bends 23 will be in contact with the supporting surface and the chair will be supported by said ends of the arms l8 and the rearwardly extending supporting portions 14 of the frames ill.

The arms l9 are also provided with eyes 23 similar to the eyes 2!. The eyes 2| and 23 of the arms 18 and IQ of the auxiliary frames are slidable on the upstanding frame members l between a position in which the eyes 2! engage the bends 22 and a position determined by the stop collars 24. These collars are slidable on the upstanding portions H] of the frame, each being provided with a set screw (not shown) whereby it can be fixedly secured to the frame in any adjusted position. When the collars are positioned adjacent the bends connecting the transverse portions H and the upstanding portions In of the frame, as shown, and the chair is supported in its Fig. 2 position, the seat will be as far below the level of the hook shaped upper end of the frame as possible; to raise the level of the seat relative the frame, it is only necessary to adjust the collars 24 upwardly on members Hi. I A compression coil spring 25 is mounted between the collars 24 and the eyes 23. The springs 25 will slide along on the upstanding frame members I!) so that when the parts are in the position shown in Fig. l the springs 25 will slide to a position where the same rest on the eyes 23, but in the position shown in Fig. 2 the springs will have one end of each thereof in engagement with the collars 24 and the other end of each thereof will be in engagement with the eyes 23, the springs being compressed when in the position shown in Fig. 2 so that the auxiliary frames will have a cushioned or resilient mounting on the frame.

A compression coil spring 26 is also provided between the eyes 2| and 23, preventing any permanent distortion of the auxiliary frames due to the weight supported from the seat, as the springs 26 will act as auxiliary supportin means for the seat, limiting approach of the eyes 23 toward the eyes 2| when the parts are in the position shown in Fig. 1.

A seat 21 is provided, which is, preferably, a board of suitable width and thickness, provided with openings through which hook bolts extend. The latter bolts have the hook ends 28 that engage the arms 19 and are clamped in position by means of the acorn nuts 29. When the nuts are tightened up on the hook bolts, the hooks 28 will firmly clamp the seat and the rod-like arms 19 together, so that there is no possibility of any swinging movement of the auxiliary frames relative to the main frame or of the seat relative to the auxiliary frames. However, if the one set of hook bolts is loosened by loosening the nuts 29, the hook portions 28 will move far enough away from the surface of the seat 21 to permit disengagement of the hook portions from the member [9. By disengaging the seat from one of the members 19 in this manner, the seat of hooks 28 into a position adjacent the one auxiliary frame or in a position in substantial alignment with the one auxiliary frame and the two auxiliary frames can then be swung inwardly toward each other ,36 in the seat for adjusting the bracket which the frame may tion with said side members 4 on the main frame so as to make a compact package of the chair for either shipping purposes or storing purposes.

A back 30 of flexible material, such as canvas, is provided for the chair, the back having a pair of pockets formed in the opposite ends thereof by turning back a portion of the material, as shown at 3|, and detachably securing said portion to the main body portion of the fabric by means of snap fasteners 33. The seat is provided with a U-shaped bracket 34 having a transversely extendin portion received in one of said pockets, while the transverse portion ll of the frame ill is received in the other pocket. The opposite legs of bracket 34 are slidably mounted in bores relative to the seat. It will be obvious that when the canvas back member 30 is in the position shown in Fig. 1 the depth of the seat can be changed somewhat by adjusting the position of the bracket member above described; it also will be clear that when the seat is in the position shown in Figs. 2 and 3 the canvas back-supporting member 30 is in a folded position under the seat 21.

In order to hold a child in the seat when it is in the position shown in Figs. 2 and 3, a pair of straps 3? and 38 are provided, these having tubular eyes 39 embracing the springs 26 on the upstanding frame portions [0 for securing said straps to the frame. Strap 38 has a buckle 40 engaging with the other strap 31 in a well known manner for securing the child in position in the seat. It will be obvious that the straps can be adjusted up and down to the desired holding position on the upstanding frame members Hi.

The frame members comprising the upstanding portions l0 and the portions H, l4, l5 and i6 are preferably, made of rod, or tubing, while the auxiliary frame members comprising the portions l8, l9 and 20 may be made of rod, as shown, or of strap metal punched out to provide eyes corresponding to 2! and 23.

It is believed that from the above it will be obvious that a convertible chair is provided that is adapted for use either on a floor or other similar supporting surface, or which may be supported from a seat, such as an automobile seat, in a hanging position. Also it will be noted that by the construction provided the chair can be kept clean and sanitary because the fabric portion thereof is readily removable, and furthermore the chair is capable of being folded into a compact package that is easy to transport from place to place. By providing the coil springs a resilient or cushioned mounting is provided for the seat that is highly occupies the same.
