The specific embodiment

At first, please cooperate shown in the detailed description of consulting Fig. 1: the structure of a kind of fitness equipment of lying on the back of the utility model, preceding foot rest 1 by the tool bending, rear leg 2, lie by frame 3, foot hook frame 4 four large parts institute pivot structure becomes, wherein 4 of this foot hook frames are between rear leg 2 and give the pivot knot, lie and then between preceding foot rest 1, close the position with the pivot roped party by frame 3, this lie by frame 3 end ends again with a connecting rod 5 pivots, make on the position of institute's pivot knot between the other end of connecting rod 5 and foot hook frame 4 and the rear leg 2, by a plug 6 it combination is fixed, wherein the side, position of institute's pivot knot also has a short projection 31 respectively between lying by frame 3 and preceding foot rest 1, but the straddle 11 of lifting-rotating type, and the top position at this preceding foot rest 1 and rear leg 2 pivots then is provided with soft seat cushion 12, foot pad 13, on lying, then be provided with the rotating roller set 32 of number row by frame 3, again in the left side of rear leg 2 with foot hook frame 4, right both sides are respectively equipped with several short studs 21,41, this short stud 21,41 and coating by continuous 8 of soft bubble, and the left side, the top of foot hook frame 4, right both sides each by one by elastic cable 71 with pull handle 72 hand controllers of being formed 7.

So, user A is after being seated at this seat cushion 12, and A1 subsides in health back are touched on lying by the roller set in the frame 3 32, both feet A2 then is placed in the short stud 41 of foot hook frame 4, the straddle 11 of foot rest 1 kept off and stagnating before the short projection 31 by frame 3 of lying this moment was subjected to, the buttocks A3 that makes health is a central point and whole health is done stretching, extension (as Fig. 2-A) and shrink (as the motion of lying on the back of Fig. 2-B), simultaneously also by lying by the roller set in the frame 3 32 back A1 that harmonizes the body, so just can make on the whole health, the lower part of the body all obtains impartial active action, and then reaches body-building effect.

Moreover, when the hand controller 7 that again both hands A4 is being pulled and supported respectively on foot hook frame 4, and utilize the elastic reaction of its elastic cable 71, think it is that buttocks A3 with health is a central point and whole health is done stretching, extension (as Fig. 3-A) and shrink (as the motion of lying on the back of Fig. 3-B) equally, and health back A1 also obtains synchronous massage, certainly both hands A4 also obtains motion, and being that the upper and lower half body of whole health is the same can obtain impartial active action, and then reaches body-building effect.

Moreover, when user A is seated at this seat cushion 12, A1 subsides in health back are touched on lying by the roller set in the frame 3 32, thigh is abutted on the foot pad 13, and double-legged A2 then is placed in the short stud 21 of rear leg 2, straddle 11 other faces of foot rest 1 kept off stagnant (as Fig. 4-A, Fig. 4-A-1) before 31 of the short projections by frame 3 of lying this moment were subjected to, so can be equally be central point and the upper part of the body of health is up straightened start (as Fig. 4-B) with the buttocks A3 of health, can certainly add the activity operations that pulls and supports of both hands, to reach the stiffening effect of privileged site.

If when after finishing using, wanting to tidy up this fitness equipment, then be by foot hook frame 4, rear leg 2, lie by the pivot knot effect between frame 3, connecting rod 5, the preceding foot rest 1, plug 6 taking-ups are pulled down, what just whole fitness equipment can be compressed to minimum space folds operation (as Fig. 5-A, Fig. 5-A-1, Fig. 5-A-2, Fig. 5-B, Fig. 5-C), with convenient collection and do not take up space again.

To sum up institute is old, and the utility model has above-described efficacy exertion really, meets the establishment key element of novel patent, earnestly asks and awards accurate legal patent right.
