Please refer to Figure 1~6 together. 1 is an exploded view of an embodiment of an exercise machine. 2 is a partial cross-sectional view of the connecting rod and the linear elastic member of FIG. 1. 3 is a partially assembled perspective view of the exercise machine of FIG. 1. 4 and FIG. 5 respectively show a partial cross-sectional view of the second bracket in FIG. 1 before and after swinging. FIG. 6 is a schematic view showing the operation of the exercise machine of FIG. 1. The structure and operation of the following embodiments can be fully explained using the foregoing figures.

Referring to FIG. 1 to 3 together, the exercise machine includes a first bracket 100, a second bracket 200, a protrusion 300, a linear elastic member 400, a link 500, an adjustment module 600, a pulley 700, and a Cushion 800. The convex portion 300 includes an abutting end 310 and a fixed end 320. The linear elastic member 400 includes a first end 410 and a second end 420. The connecting rod 500 is connected by a spherical connecting end 510, a shaft 520 and a The clamping end 530 is composed of a locking component 610, a locking component 620, and a screw fitting 630.

In the structure of the above-mentioned exercise machine, the second bracket 200 is pivotally connected to the first bracket 100, and the convex portion 300 is pivotally coupled to the second bracket 200. The convex portion 300 and the second bracket 200 are coaxially pivotally connected to the first bracket 100, and the connecting rod The force applying end 530 of the 500 is pivotally connected to the fixed end 320 of the convex portion 300. During the swinging of the second bracket 200, the link 500 is driven by the convex portion 300 to move the linear elastic member 400. The linear elastic member 400 is displaceable, telescopic, and elastic on the first bracket 100, wherein the first end 410 is disposed on the first bracket 100.

The second end 420 of the linear elastic member 400 includes an accommodating space 421, and the end of the accommodating space 421 is inwardly contracted to form a smaller opening 422. The opening 422 has a smaller aperture than the diameter of the spherical connecting end 510, and The diameter of the shaft 520 is limited to the diameter of the shaft 520, so that the ball joint end 510 is restricted to the accommodating space 421 of the second end 420, and the shaft 520 can be oscillated and contracted into the opening 422.

Referring to FIG. 1 and FIG. 4 together, before the second bracket 200 swings, the linear elastic member 400 pulls the connecting rod 500 through the elastic force, and the connecting rod 500 interlocks the fixed end 320 of the convex portion 300, so that the convex portion 300 abuts. end 310 is closely abutted against the inner wall of the first bracket 100. At the same time, since the convex portion 300 and the second bracket 200 are coaxially pivoted to the first bracket 100, the second bracket 200 is in a stable state without being affected by the weight of the cushion 210 or the second bracket 200 itself. The weight causes the second bracket 200 to swing or fall down.

Referring to FIG. 1 and FIG. 5 together, when the second bracket 200 is swung, the abutting end 310 of the convex portion 300 is away from the inner wall of the first bracket 100, and the fixed end 320 of the convex portion 300 pulls the biasing end 530 of the connecting rod 500, and is transparent. The tight connection of the ball joint 510 and the second end 420 elongates the linear elastic member 400. When the external force pushing the second bracket 200 is moved away, the second bracket 200 returns to the state before the swing. Further, the second bracket 200 and the convex portion 300 of the above exercise machine may be integrally coupled.

The adjustment module 600 adjustably positions the first end 410 of the linear elastic member 400. The two ends of the locking member 610 of the adjustment module 600 respectively lock the first end 410 and one end of the screw lock 620, and the screw lock 620 The other end is screwed with the screw fitting 630. Since the screw fitting 630 is positioned on the first bracket 100, the screw member 630 can be displaced by the rotating screw fitting 630, thereby being able to move and adjust the position of the latch member 610 within the first bracket 100. If the position of the locking member 610 is closer to the screw fitting 630, the closer the first end 410 of the linear elastic member 400 is to the screw fitting 630, the length of the linear elastic member 400 is elongated, thereby increasing the linear elastic member 400 at the reciprocating pivot. The restoring force of the pendulum; conversely, if the position of the locking member 610 is farther from the screw fitting 630, the closer the first end 410 of the linear elastic member 400 is to the convex portion 300, resulting in the shortening of the length of the linear elastic member 400, Further, the restoring force of the linear elastic member 400 at the time of reciprocating pivoting is reduced.

The pulley 700 is coaxially disposed on the first bracket 100 coaxially with the second bracket 200 and the convex portion 300. The second bracket 200 and the convex portion 300 can be reciprocally pivoted relative to the first bracket 100 by the pulley 700. In addition, the seat cushion 800 can be disposed on the first bracket 100 for carrying the body of the user. The second bracket 200 further includes a cushion 210. The cushion 210 can be a foam material or a cushioning material, and can be used to bear against the user's body.

Please refer to FIG. 6 , which illustrates that the second bracket 200 can be forced to pivot relative to the first bracket 100 and the resetting force provided by the linear elastic member 400 can be used to reset the second bracket 200 to the position before pivoting. . The user can sit on the cushion 800 and rest the back against the cushion 210, in which case the exercise machine can be used to assist in the sit-up exercise. Furthermore, the user can also lie on the top of the exercise machine and push the top cushion 210 with the chest. In this case, the exercise machine can be used to assist the push-up body movement. In addition, the user can also place the exercise device under the foot, so that the two feet are respectively stepped on the two cushions 210, and the user's feet can be stepped at the same time or alternately to make the second bracket 200 pivot relative to the first bracket 100. In this case, the exercise machine can be used to assist in pedaling. In addition, the user can use the fitness machine instead of lying on the side, holding the hand, lifting the foot on the exercise machine, etc. Perform a wide range of exercise assists.

It can be seen from the above embodiments that the present invention has the following advantages: First, the exercise device that uses the rigid link to link the linear elastic member can quickly limit the displacement, swing and bounce range of the linear elastic member, so that the linear elastic member can be stabilized. Ground expansion and contraction. Secondly, the special connecting design of the rigid connecting rod and the linear elastic member can limit the linear elastic member to the first bracket without touching the inner wall of the first bracket, thereby avoiding the sound and the component caused by the touch. Wear, achieve noise-free and extend component life.

The present invention has been disclosed in the above embodiments, and is not intended to limit the present invention, and the present invention can be variously modified and retouched without departing from the spirit and scope of the present invention.
