DETAILED DESCRIPTION

(12) FIG. 1 is a right side view of an elasticity adjusting mechanism of an exercise equipment according to one embodiment of the present disclosure. In FIG. 1, the elasticity adjusting mechanism of an exercise equipment includes a base 100, a staggered frame 200, an elastic body 300, a force exerting member 400 and an adjusting socket 500.

(13) As shown in FIG. 1, the base 100 stands on a ground and supports the exercise equipment. The staggered frame 200 includes a pivot portion 211, The pivot portion 211 is as center of the staggered frame 200 can be divided into a middle section 210, a front section 220 and a rear section 230. The pivot portion 211 pivots on the base 100; thereby the staggered frame 200 and base 100 are pivotally connected for forming a foldable frame in X-shape.

(14) In the front of the exercise equipment, the front section 220 includes an extended socket 221. The rear section 230 includes a positioning socket 231, and the positioning socket 231 is pivoted on the staggered frame 200 via the pivot portion 211. Moreover, the positioning socket 231 can be integrated or weld with the staggered frame 200 in different positions.

(15) The elastic body 300 passes through the extended socket 221. The elastic body 300 can be a flexible rope that the elastic force thereof is variable in accordance with extension amount. One end of the elastic body 300 is disposed on the positioning socket 231, and the other end of the elastic body 300 is connected to the force exerting member 400 far stretching reciprocately.

(16) The staggered frame 200 includes a plurality of fixed portions 240. The fixed portions 240 are located at different positions of the staggered frame 200. In one example, the fixed portion 240 can be disposed on the rear section 230 for increasing wining area. The adjusting socket 500 is also passed by the elastic body 300 and is assembled with one of the fixed portions 240 selectively.

(17) Since the positioning socket 231 is fixed on the staggered frame 200, the distance between the adjusting socket 500 and the positioning socket 231 is variable in accordance with the position of the adjusting socket 500. Therefore, the path from the adjusting socket 500 to the force exerting member 400 and the elastic force of the elastic body 300 will be changed, so as to adjust the resistance of the exercise equipment.

(18) FIG. 2A is a perspective view of the elasticity adjusting mechanism of FIG. 1. FIG. 2B is another perspective view of the elasticity adjusting mechanism of FIG. 1. In detail, the elastic body 300 is arranged in the back of the staggered frame 200, and the base 100 is hollow in position near the pivot portion 211 as shown in FIG. 2B, so that the elastic body 300 can pass through the base 100 and extend continuously.

(19) The adjusting socket 500 can include a pulley 510, and the elastic body 300 can be driven by the pulley 510. The elastic body 300 changes direction thereof and connects to the positioning socket 231 after passing through the pulley 510. Moreover, the elastic body 300 can be further extended through the pulley 510.

(20) FIG. 2C is a schematic view showing an operation state of the elasticity adjusting mechanism of FIG. 2A. In FIG. 2C, the positioning socket 231 may rotate slightly when the elastic body 300 is stretched. In one example, the positioning socket 231 can include a pivot member 231A (e.g. a casing) set on the positioning socket 231 that can be driven by the elastic body 300.

(21) Therefore, the pivot 231A can adjust the direction during the rotation with the positioning socket 231 and the elastic body 300, so as to keep the transition of power in straight line for balance and stable when operating the exercise equipment.

(22) FIG. 2D is an enlarged view of an adjusting socket of the elasticity adjusting mechanism of FIG. 2A. In FIG. 2D, the adjusted socket 500 includes a combined body 501 and a combined body 502. The combined body 501 and the combined body 502 are screwed with each other, and a withstanding portions 521 in the combined body 501 is locked with the holes of the fixed portions 240. Because the elastic body 300 is tightened the adjusted socket 500 will abut the rear section 230 during the operation. In contrast, when the elastic body 300 is loosened, the withstanding portions 521 can be slightly lifted up by a gap between the adjusted socket 500 and the rear section 230, therefore each of the fixed portions 240 which is fixed with the adjusted socket 500 can be selected by controlling the elastic body 300 and the withstand portions 521.

(23) FIG. 3A is an exploded and enlarged view showing a portion of another type of the adjusting socket of the elasticity adjusting mechanism of FIG. 2A. FIG. 3B is an exploded and enlarged view showing a portion of still another type of the adjusting socket of the elasticity adjusting mechanism FIG. 2A. FIG. 3C is an exploded and enlarged view showing a portion of yet another type of the adjusting socket of the elasticity adjusting mechanism of an exercise equipment of FIG. 2A. FIG. 3D is an exploded and enlarged view showing a portion of further another type of the adjusting socket of the elasticity adjusting mechanism of an exercise equipment of FIG. 2A. In FIG. 3A, FIG. 3B, FIG. 3C and FIG. 3D, various types of the adjusted socket 500 are shown. Other characteristics of the adjusted socket 500 are the same as the aforementioned embodiments, there is on repeating herein.

(24) In FIG. 3A, the fixed portion 240 is composed of two bolt holes. For the convenience of disassembly, the adjusted socket 500 can be formed by combining two combined bodies 501 and 502. The shapes of the combined bodies 501 and 502 are corresponded with the rear section 230, thus the two combined bodies 501 and 502 can be clamped with the staggered frame 200, and then bolted on two sides of the fixed portion 240.

(25) In FIG. 3B, the adjusted socket 500 can include two movable members 520 rotatably and symmetrically disposed at two side of the adjusted socket 500. Each of the movable members 520 has a withstanding portion 521, and the withstanding portion 521 selectively assembles with one of the fixed portions 240. Furthermore, each of the movable members 520 is corresponded to a recovering member 530, and the recovering member 530 extends elastically to push against the movable member 520 when compressed. The recovering member 530 can be a linear spring.

(26) In detail, the recovering members 530 are compressed and extended outwardly, such the movable members 520 won't be taken off from the fixed portion 240. Therefore, a user can change the position of the adjusted socket 500 by holding the movable members 520 to against the elastic force of the recovering members 530. The feature can avoid accident that the adjusted socket 500 shoots up resulting from unlocking the fixing inadvertently.

(27) In FIG. 3C, the combined bodies 501 and 502 are screwed with each other and are bolted by a T-shaped withstanding portion 521. Moreover, the tightness of the withstanding portion 521 can be adjusted by a knob, thereby releasing or fixing the adjusted base 500.

(28) In FIG. 3D, a bolt hole (not labeled) is formed at the assembling surface of the combined bodies 501 and 502 and aligns with the fixed portion 240. After the adjusted socket 500 bolts with the rear section 230, the recovering member 530 pushes and fixes the adjusted socket 500 bolts to the fixed portion 240.

(29) FIG. 4 is an exploded view of the adjusting socket of an exercise equipment according to another embodiment of the present disclosure. In FIG. 4, one end of the elastic body 300 is pivoted to passes through the pulley 510 and pivots the adjusted socket 500, namely, the end of the elastic body 300 is movable. It should be mentioned that the adjusted socket 500 in FIG. 4 is only for description so will not be a limitation. Alternatively, the adjusted socket 500 can be replaced by another one shown in FIG. 3A, FIG. 3B, FIG. 3C or FIG. 3D.

(30) In the case of the above embodiment, the positioning socket 231 is optional because the elastic body 300 connects to the adjusting socket 500. The rear section 230 can be hollow as the first embodiment, or be solid as shown in FIG. 4. The positioning socket 231 is pivoted into the rear section 230 via the pivot member 231A. Also, the pivot member 231A can be replaced by the pulley 510. Therefore, the extension amount of the elastic body 300 is more intuitive. Further, the setting not merely saves space by putting the positioning socket 231 into the rear section 230, but provides the path for the elastic body 300.
