One object of my invention is to provide a chair structure that has a movably-mounted seat, which may take the place of swings or cradles, and which can be given a movement that is smoother than a cradle movement and is less likely to cause nausea than in the case of cradles and swings.

Another object of my invention is to provide a movable seat structure of simple form and light weight, which may be conveniently moved from one room to another.

Some of the forms which my invention may take are shown in the accompanying drawings, wherein Figure 1 is a plan view; Fig. 2 is a side elevational view; Fig. 3 is an enlarged view, taken on the line III-III of Fig. 2; Fig. 4 shows a modified form of the structure of Fig. 2; Fig. 5 is a fragmentary plan view thereof, and Fig. 6 is an enlarged view taken on the line VI--VI of Fig. 5.

The structure includes a rectangular frame or base 5, two pairs of uprights 6, of spring steel or the like, an upper rectangular frame I and a seat frame 8. The lower ends of the spring arms or uprights 6 are secured to the frame 5 by means of bolts 9, or in any other suitable manner, and the upper bent ends of the uprights 6 are similarly bolted to the frame I. These various connections may be made detachable, in order to facilitate assembling and disassembling of the structure for storage or shipment.

The seat frame 8 carries a canvas seat In, which has suitable side and back portions l I and I2, and a front. portion l3, the front portion being provided with holes through which the infants feet may extend. The upper edges of the seat portions H, I! and I3, are secured to the frame 8 by looping the canvas or other cloth from which the seat may be formed around the frame and sewing the edges thereof to the body of the fabric, as shown more clearly at Illa in Fig. 3. 'The frame 8 itself is detachably secured to the frame I by means of bolts l5.

The portion l3 of the canvas seat has an extension l6, which may serve as a convenient receptacle or shelf for playthings and the like. A cross rod I1 is provided on the seat frame 8 and is shown as carrying slidably-supported playing devices, after the manner of an abaccus.

The uprights 6, being of spring metal, permit a swaying movement to be given to the seat, and such movement will continue in a gentle manner for a considerable period of time after a substantial impulse is imparted. thereto. The impulse can be imparted bypushing the upper. frame,'or by a? person sitting near the chair: and occasionally pushing one of theuprights 6 with the foot. In-the case of older infants, their feet and legs will extend far enough forwardly that they can push against the forward uprights 6, with their toes, to induce the desired swaying movement.

The swaying movement is enhanced, and stiffness of operation reduced in the present instance, where the uprights have bends formed therein, to a greater extent than if the uprights were not bent, but my invention contemplates also, the provision of straight uprights to which the seat frame may be fastened.

A given impulse will cause swaying movement for a longer period of time than in the case of a cradle, and the motion is smoother and more regular. Furthermore, the inwardly bent ends of the uprights 6 facilitate the return of the seat to neutral or central position when swaying forces have been dissipated, because of the fact that the points of connection to the depending upper ends of the uprights are closer to the center of the structure than are the points at which the uprights are connected to the bottom frame 5.

g The seat has the further advantage over ordinary swings in that the flat strips 6 resist side sway, although they are readily flexible in the direction of normal swinging movement. Also, the uprights give a horizontal movement to the seat comparable to such as would be produced by parallel link motion, instead of the purely arcuate movements which take place in ordinary swings.

Referring now to Figs. 4, 5 and 6, I show a structure which is of simplified form and which is arranged to facilitate assembly of the seat structure and the supporting frame. In this structure, a rectangular base 20, uprights 2|, and a seat frame 22 are provided, and are similar to the corresponding parts of the structure of Fig. 2 The seat frame 22, however, is directly attached to the downwardly bent ends or inner leg portions 23 of the uprights 2|. Each leg portion is reversely bent at its lower end to form a U-shaped.

hook or socket 24, for receiving the seat frame 22 therein. The sides of the hooks preferably are bent to form a slightly restricted throat, so that the seat frame will be frictionally retained in the hooks against accidental disengagement therewith.

A suitable seat 25 is secured directly to the frame 22, and the fabric or other material of which the seat is composed is cut away at those bar of spring-like material adjacent eachcorner portions adjacent to the uprights to expose the of the frame, having its lower end secured to the frame, for direct engagement with the hooks 24. frame, the bars extending vertically in straight I claim as my invention:- lines throughout the major portion of their length,
