'5 Claims.

The present invention relates ,to a chair which may be rocked and swiveled to any desired posiv tion while maintaining positive control over the balance of the chair.

Other chairs have been devised heretofore Whichhave been provided with means for rocking them and for swiveling them to various po- The operation of such chairs has been chairs in' common domestic use. It is the primary object of the present invention to provide ,a-chair having a rockingand swiveling supporting assembly by means of which it is possible to .incline the seat of the chair at any desired angle,

and to rotate the seat to any desired position.

It is another object of the present invention to provide a chair mounting which will make possible the rotation and rocking of the chair to any desired angle and position easily, positively, and

with maximumsafety. v

Still another object of the present invention ,isthe provision of a rocking and rotating chair provided with a round base which may be used as a wheel so that, upon tilting. the 'chair, it may be rolled to a new position with. a minimum of effort even though the chair is of substantial size and weight.

The manner in which the foregoing andother objectsof the present invention are accomplished will be apparent from the following specification and claims considered together with the drawings wherein Figure 1 is-a ,side elevation, partly in section, of tharesenuy described chair, the section being-taken along the lines |l of Fig- Figure "2 is a sectional view taken along the lines 2-2 of Figure 1;

- Figure 4 is a fragmentary View taken along the lines 4- .4 of Figure 5, and illustrating an alternate, spring v controlled, rocking assembly for use in the chair of the present-invention;

- Figure 5 is a plan view taken along the lines 5-5 of Figure 4;

Figure 6 is a fragmentary, sectional view of an in which it may be moved from place to place.

" fTh'e present-1y Referring now more particularly to Figures 1 to 3: i

v described chair is provided with a chair seat I!) which may be variously constructed and designed althou h, as illustrated, it preferably is of the substantial upholstered type in conventional use. The chair seat is mounted upon a rocking and swiveling supporting assembly comprising broadly means whereby the seat may be rocked, means whereby the seat may :be swiveled, and spring means operatively associated with the rocking and swiveling means for controlling their actiori.;-

Thus the supporting assembly may comprise a substantially fiat base member I I, which rests flat upon the floor and preferably is circularior a reason which will be developed more fully hereinafter. Interposed between the base II and an intermediate platform I2 are the swiveling means indicated generally at [3. Although as will be apparent to one skilled in the art, a variety of swiveling means of suitable construction may be employed, the construction selected for the purposes of illustration comprises (Figure 3) a lower plate 14 and an upper plate [5, the two plates having therebetween a plurality of ball bearings !6 contained in a ball bearing race l1. Plate I4 is affixed to base H and plate IE to platform [2 by means of screws, bolts or the like. The two plates then may be fastened together by means of a bolt or rivet 22, thereby rotatably interconnecting the base and th-e'platform on which the chair seat rests.

The platform 12 is provided with a pair of verticallyextending side pieces lZa for supporting the rockers l8 which, in turn, are attached-to the frame of the chair seat [0. The rockingmotion of the rockers on the platform, as Well as the swiveling motion of the chair about the swivel assembly l3, are controlled through spring means interconnecting the rockers and the platform. In the embodiment illustrated in Figures 1 to' 3, inclusive, the spring means comprises a pair of coil springs l9, lil alssociated with each rocker, and

mounted by means of brackets 20, 20 attached to struction similar to that of the swivel assembly l3 of Figures 1 to 3.

The platform 21 is attached to the swivel means 26 and also to the cross bars 28, 28 of the spring assembly 29 which, in turn, is attached to the frame 30 of the seat of the chair. Hence the chair seat is resiliently cushioned on the spring assembly so that it may be-rocked back and forth under positive control at all times.

Still another spring means for supporting the seat of the chair of the present invention is illustrated in Figures 6 and 7. In this construction, the chair is mounted on the base 35. Attached to the base is the swivel assembly 36, the latter being attached to the platform 31. As is apparent from Fig. 6, platform 31, like platform l2 of the embodiment of Fig. 1, may be formed from a horizontal section having a pair of upstanding side pieces anixed one to each of its ends. Attached to the platform is the spring member 38 comprising two crossed U-shaped sections having their arms connected at their lower ends to parallel spaced sections by volute springs, the spaced sections being attached one to each of the side pieces of the rocker platform, and the U-shaped sections being attached to the chair seat 39. Hence this spring means, like the spring means employed in the embodiments of Figures 4 and 5, serves to support the chair resiliently so that it may be rocked back and forth under the positive control of the springs.

The manner of use of the'chair of the present invention in all of the above described embodiments is similar in that the chair may be placed conveniently to other articles of furniture, as a radio. The person sitting in the chair then may recline to any desired degree, the reclining motion being controlled through the spring construction employed in the supporting assembly. From this position, the chair is in perfect balance so that only slight pressure exerted by the foot against the floor is suflicient to rotate the chair until it faces in a different direction. The degree of rotation may be controlled perfectly and there is no hazard of becoming overbalanced in the chair during the swiveling action as is the case where the chair is not provided with spring means for controlling the rocker and swiveling. Furthermore, when it is desired to move the chair from one place to another, all that is necessary is to tilt it back on the edge of its circular base so that, by the application of only a slight force, the chair may be moved to another place, the circular base cooperating with the swivel and acting as a wheel during this operation. In this manner, there is provided a chair construction having maximum comfort, safety, adjustability to any desired sitting position, and transportability to any desired location.
