DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1-4, a fitness device in accordance with the present invention is shown comprising a chair body 11 and a plurality of support frame bars 2.
The chair body 1 comprises a chair seat 11, a chair back 12 obliquely upwardly extended from a rear side of the chair seat 11 defined with the chair seat 11 a predetermined contained angle, two handheld portions 111 bilaterally located at and formed integral with front bottom sides of the chair seat 11, a circular recess 112 located in the top wall of the chair seat 11, an axle hole 114 located at the center of the circular recess 112, an axle bearing 113 mounted in the axle hole 114, a rotating wheel 13 horizontally and rotatably mounted in the circular recess 112 and having a wheel axle 131 downwardly extended from the center of the bottom side thereof and rotatably coupled to the axle bearing 113, a handlebar 14 fixedly and transversely mounted at the back side of the chair back 12 on the middle and respectively protruding over two opposite lateral sides of the chair back 12, a top connection bar 16 located at the top side of the chair back 12, a headrest 15 adjustably mounted at the top connection bar 16, and a ball bearing ring 17 set between the rotating wheel 13 and the circular recess 112. The ball bearing ring 17 comprises an outer race 171 fixedly mounted at the bottom side of the rotating wheel 13, an inner race 172 fixedly mounted in the circular recess 112, and a plurality of balls 173 rotatably supported between the outer race 171 and the inner race 172. During rotation of the rotating wheel 13, the balls 173 keep the rotating wheel 13 in balance.
The support frame bars 2 are arranged in parallel, each defining a first base frame bar portion 21, a second base frame bar portion 22 longitudinally connected to one end of the first base frame bar portion 21 and defining with the first base frame bar portion 21 a contained angle smaller than 180 degrees, a first connection frame bar portion 23 extended from the other end of the first base frame bar portion 21 at a predetermined angle and fixedly connected to the bottom side of the chair seat 11, a second connection frame bar portion 24 from the other end of the second base frame bar portion 22 at a predetermined angle and fixedly connected to the bottom side of the chair back 12.
Further, a transverse reinforcing bar 25 can be connected between each two adjacent support frame bars 2 to reinforce the structural strength. Further, anti-slip pads 3 can be provided at the bottom side of the first base frame bar portion 21 of each support frame bar 2. In this embodiment, the fitness device comprises two support frame bars 2. However, this support frame bar arrangement is not a limitation.
Referring to FIGS. 5 and 6 and FIG. 4 again, the user can place the fitness device on the floor to keep the first base frame bar portions 21 of the support frame bars 2 in direct contact with the floor, and then rest the knees on the rotating wheel 13 and hold the handlebar 14 with the hands, and then twist the body to let the knees be turned back and forth with the rotating wheel 13, achieving the desired effects of exercise (see FIG. 5). Alternatively, the user can place the fitness device on the floor to keep the second base frame bar portions 22 of the support frame bars 2 in direct contact with the floor, and then rest the hips on the rotating wheel 13, the back on the top side of the chair back 12 and the head on the headrest 15 and hold the handheld portions 111 with the hands, and then twist the body to turn the rotating wheel 13 back and forth and/or to extend and retract the legs, achieving the effects of exercise (see FIG. 6).
Referring to FIG. 7, an alternate form of the fitness device is shown. This alternate form is substantially similar to that shown in FIGS. 1-4 with the exception of the arrangement of additional stop blocks 4 that are respectively mounted at the second base frame bar portions 22 of the support frame bars 2 remote from the respective first base frame bar portions 21. The bottom edge of each stop block 4 is kept in flush with the bottom surface of the second base frame bar portion 22 of each support frame bar 2. Thus, the stop blocks 4 are workable with the second base frame bar portions 22 of the support frame bars 2 to support the fitness device on a flat surface stably.
Subject to the design that the first base frame bar portion 21 and second base frame bar portion 22 of each support frame bar 2 define a predetermined contained angle smaller than 180 degrees, the fitness device can be selectively supported on the floor to keep the first base frame bar portions 21 or second base frame bar portions 22 of the support frame bars 2 in direct contact with the floor for different types of exercises. The fitness device has the advantages of simple structure and ease of use.
