United States Patent '0 INFANTS CHAIR Edward Walter Anderegg, West De Pere, Wis.

Application March 21, 1952, Serial No. 277,867

2 Claims. (Cl. 15510) This invention relates to infants chairs or seats and is a continuation in part of my application, Serial No. 111,260, filed August 19, 1949, now Patent No. 2,679,282, granted May 25, 1954, for Infants Seat.

It is among the objects of the present invention to provide and improved infants chair or seat which can be easily and conveniently mounted in a vehicle, such as an automobile or railway coach, to support an infant on a vehicle seat, or can be used without change in a house to provide a readily portable seat for an infant or small child; which is of simplified construction and includes unitary foot formations for engaging under a vehicle seat back to retain the chair in proper position on the vehicle seat; which has a detachable back structure which may be removed to reduce the size of the chair for packaging and shipping and for subsequent storage; and which is simple and durable in construction, economical to manufacture, and neat and attractive in appearance.

Other objects and advantages will become apparent from a consideration of the following description and the appended claims in conjunction with the accompanying drawing wherein:

Figure 1 is a perspective view of an infants chair illustrative of the invention showing an infant seated therein;

Figure 2 is a fragmentary side elevational view of the chair showing structural details thereof;

Figure 3 is a cross sectional view on the line 3-3 of Figure 2;

Figure 4 is a fragmentary side elevational view showing the manner in which the chair frame engages with the seat and back cushions of a vehicle seat; and

Figure 5 is a top plan view of a foot formation form ing an operative component of the chair and adapted to engage under the back cushion of a vehicle seat.

With continued reference to the drawing, the chair comprises, in general, a frame including a pair of frame side members'10 and 11, a top frame member 12 and a back frame member 13, a base plate 14 and a fabric cover 15 detachably secured to the frame.

The frame side members 10 and 11 are formed of light metal rods bent substantially to the shape of a figure eight. The member 11 includes a substantially straight top rail 16, a substantially straight bottom rail 17 and substantially straight legs 18 and 19 connecting the endsof the top rail 16 to the respectively opposite ends of the bottom rail 17 in a manner such that the top and bottom rails are substantially parallel to each other. The crossed over legs 18 and 19'are connected to the ends of the top rail 16 by curved portions and the leg 18 is connected to the front end of the bottom rail 17 also by longitudinally curved portions; The connection between the leg 19 and the rear end of the bottom rail 17 is provided, however, by a looped portion 20 of the metal rod projecting longitudinally from the corresponding end of the bottom rail 17 with its legs contiguously disposed in side by side relationship. Intermediate its length this U-shaped or looped portion 20 is provided with an upwardly arched formation 21 and the closed end is inclined somewhat upwardly, as indicated at 22. The frame side member 10 includes the same elements as described above in connection with the side member 11, there being illustrated a leg 23 corresponding to the leg 18, a bottom rail 24 corresponding to the bottom rail 17 and a foot formation 25 projecting longitudinally from the rear end of the bottom rail 24 and conforming in all respects to the foot formation 20 2,704,567 Patented Mar. 22, 1955 on the rear end of the bottom rail 17 of the frame side member 11.

The base 14 may comprise a rectangular body of sheet metal having its opposite ends rolled over the bottom rails 17 and 24 of the frame side members to hold these bottom rails in spaced apart and substantially parallel relationship to each other. When the base plate 14 is assembled with the frame side members the foot formations 20 and 25 extend outwardly from the same edge of the base plate, as is particularly illustrated in Figure l.

The top frame member 12 is a U-shaped structure of light metal rod having straight and substantially parallel leg portions extending along and secured to the top rail of the frame side members 10 and 11 and having its arcuately curved intermediate portion extending outwardly from the ends of the top rail of the frame side portions remote from the foot formations 20 and 25. A brace bar 26 extends perpendicularly between the legs of the front frame member 12 intermediate the length of these legs and adjacent the front ends of the top rails of the frame side members.

The back frame member 13 is also a U-shaped structure of light metal rod and has angularly disposed leg portions as indicated at 27 extending along the top rails of the frame side members 10 and 11 and its intermediate portion extending upwardly from the top rails of the frame side members at the rear ends of these top rails adjacent the foot formations 20 and 25.

Sheet metal sleeves, as illustrated in Figures 2 and 3 and indicated at 30, are secured one on each top rail of the side frame members 10 and 11 intermediate the length of these top rails and these sleeves extend upwardly from the top rails and receive the ends of the legs of the front frame member 12 and also the ends of the angularly offset portions 27 of the legs of the back frame member 13. Split clamps, as indicated 31, extend around the angularly oifset portions 27 of the legs of the back frame member and the top rails of the frame side members 10 and 11 near the rear ends of the top rails and receive screws, as indicated at 32 which extend through the clamps immediately below the top rails of the frame side members. Wing nuts, as indicated at 33, are threaded one onto each of the screws 32 to contract the split clamps and firmly secure the legs of the frame member 13 to the top rails of the corresponding frame side members 10 and 11. By loosening the wing nuts 33 the back frame member 13 can be removed from the frame side members and placed between the frame side members to reduce the size of the chair for packaging and shipment and for subsequent storage or transportation.

The foot formations 20 and 25 are formed permanently on the frame side members but do not interfere in any way with the use of the chair when the same is being used as a portable seat in a'house or outdoor area adjacent the house and cooperate with the back and seat cushions of a vehicle seat to firmly secure the chair in proper position on the seat cushion of such a vehicle seat.

The cover 15 is formed of a suitable fabric and includes a seat portion 35 having flaps, as indicated at 36, along opposite edges thereof which flaps extend around the legs of the top frame member and the back frame member and top rails of the frame side members and are detachably secured to the walls of the seat by snap fasteners, as indicated at 37, a doubled back portion 38 into which the curved intermediate portion of the back frame 13 is inserted, and a tray portion 39 marginally secured to the intermediate portion of the top frame member and to the brace rod 26 by flaps, as indicated at 40 detachably secured to the wall of the tray by suitable snap fasteners, as indicated at 41.

The invention may be embodied in other specific forms without departing from the spirit or essential character isties thereof. The present embodiment is, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are, therefore, intended to be embraced therein.

What is claimed is:

1. In an infants seat, a pair of frame side members disposed in spaced apart and parallel relationship to each other and each including a length of metal wire bent to provide a straight bottom rail, a straight top rail and crossed over struts extending one from each end of said bottom rail to the respectively opposite ends of said top rail holding said bottom and top rails in spaced apart and parallel relationship to each other, means connected between the bottom rails of said side members holding said side rails in spaced apart and substantially parallel relationship to each other, means connected between the top rails of said side members holding said top rails in spaced apart and substantially parallel relationship to each other, and extensions on said bottom rails at corresponding ends thereof for engagement under a vehicle seat back to hold the chair in upright position on the associated vehicle seat, each of said extensions comprising a doubled-back portion of both the bottom rail and the downward and rearwardly extending portion of a cross strut of each side member.

2. In an infants seat, a pair of frame side members disposed in spaced apart and parallel relationship to each other and each including a length of metal wire bent to provide a straight bottom rail, a straight top rail and crossed over struts extending one from each end of said bottom rail to the respectively opposite ends of said top rail holding said bottom and top rails in spaced apart and parallel relationship to each other, means connected between the bottom rails of said side members holding said bottom rails in spaced apart and substantially parallel relationship to each other, means connected between the top rails of said side members holding said top rails in spaced apart and substantially parallel relationship to each other, and extensions on said bottom rails at corresponding ends thereof for engagement under a vehicle seat back to hold the chair in upright position on the associated vehicle seat, each of said extensions comprising a doubledback portion of both the bottom rail and the downwardly and rearwardly extending portion of a cross strut of each side member, said bottom rail cross strut portions extending side by side and being formed intermediate their ends with upwardly bowed parts aligned transversely thereof.
