  The reversing member of a conventional reciprocating clamping fitness device uses a torsion spring or a linear elastic member, but the elasticity of the torsion spring is too large to fit the user who requires a small restoring force, and the torsion spring easily fatigues And deform. Also, if the restoring force needs to be adjusted, it is necessary to convert a torsion spring with a different restoring force, which is inconvenient to use and convert, and is not suitable for many user groups that require different degrees of force. . Therefore, it is difficult for the user of the conventional product to adjust the torsion force of the torsion spring by himself / herself, and the effect of using the conventional technique is limited.

  Further, when a linear elastic member is used as the restoring member, in Patent Document 1, the fitness device has an appropriate restoring force when the linear elastic member is connected or moved directly or indirectly by a cable to swing back and forth with the fitness device. Disclosed. The user can adjust the restoring force of the linear elastic member by the cable himself to reach the customization requirement. However, all of the conventional cables are flexible and not only need to guide the cable with many guide structures and designs while connecting and moving the linear elastic members, and the cables are effective and quick. The displacement or rotation of the linear elastic member cannot be restricted, and when the linear elastic member expands or contracts, it is too intense to easily contact other elements of the fitness equipment. As a result, the user's comfort and willingness to purchase are reduced, and the life of the fitness device element is shortened.

FIG. 6 is an operation schematic diagram showing the fitness device of the present embodiment. The following structure and operation of the present embodiment can be sufficiently described based on the respective drawings.

  As shown in FIGS. 1 to 3, this fitness device includes a first support frame 100, a second support frame 200, a convex portion 300, a linear elastic member 400, a connecting rod 500, and an adjustment module 600. The pulley 700 and the saddle 800 are provided. The convex portion 300 includes a contact end portion 310 and a fixed end portion 320, the linear elastic member 400 includes a first end portion 410 and a second end portion 420, and the connecting rod 500 is The spherical connection end 510, the rod body 520, and the force acting end 530, and the adjustment module 600 includes an engagement member 610, a screw fastening member 620, and a screw member 630.

  In the structure of the fitness device, the second support frame 200 is rotatably supported by the first support frame 100, and the convex portion 300 is rotationally coupled to the second support frame 200. The force acting end portion 530 of the connecting rod 500 is rotatably supported by the fixed end portion 320 of the convex portion 300. The force acting end portion 530 is rotatably supported by the first support frame 100 coaxially with the second support frame 200. . While the second support frame 200 is rotating, the connecting rod 500 is moved by the convex portion 300 to expand and contract the linear elastic member 400. The linear elastic member 400 can be displaced and expanded and contracted, and can be bounced in the first support frame 100, and the first end portion 410 is provided in the first support frame 100.

  The second end 420 of the linear elastic member 400 includes a storage space 421, and the end of the storage space 421 contracts inward to form a hole 422. The diameter of the hole 422 is the diameter of the sphere connection end 510. Smaller than the diameter of the rod body 520, which restricts the position of the sphere connection end 510 within the storage space 421 of the second end 420 and allows the rod body 520 to rotate into the hole 422. Can expand and contract freely.

  As shown in FIGS. 1 and 4, before the second support frame 200 rotates, the linear elastic member 400 pulls the connecting rod 500 by elasticity, and the connecting rod 500 is moved to the fixed end 320 of the convex portion 300. In conjunction with this, the contact end portion 310 of the convex portion 300 is brought into close contact with the inner wall of the first support frame 100. At the same time, since the convex portion 300 and the second support frame 200 are coaxially supported by the first support frame 100 so as to be rotatable, the second support frame 200 is in a stable state without displacement, and the back cushion. Due to the weight of 210 or the weight of the second support frame 200 itself, the second support frame 200 does not rotate or fall.

  As shown in FIGS. 1 and 5, after the second support frame 200 is rotated, the contact end portion 310 of the convex portion 300 is far from the inner wall of the first support frame 100, and the convex portion 300 is fixed. The end 320 pulls the force acting end 530 of the connecting rod 500, and pulls the linear elastic member 400 long due to the tight connection between the sphere connecting end 510 and the second end 420. When the external force that presses the second support frame 200 is eliminated, the second support frame 200 returns to the state before rotating. In addition, the second support frame 200 of the fitness device may be integrally coupled to the convex portion 300.

  The adjustment module 600 adjustably positions the first end 410 of the linear elastic member 400, and both ends of the engagement member 610 of the adjustment module 600 engage with the first end 410 and one end of the screw fastening member 620, respectively.

Can be adjusted. The closer the position of the engaging member 610 is to the screw member 630, the closer the first end 410 of the linear elastic member 400 is to the screw member 630, and the length of the linear elastic member 400 is lengthened. On the contrary, the restoring force when the elastic member 400 reciprocally swings is increased. On the contrary, the farther the position of the engaging member 610 is from the screw member 630, the more the first end of the linear elastic member 400 becomes. When 410 approaches the convex part 300 and the length of the linear elastic member 400 is reduced, the restoring force when the linear elastic member 400 reciprocally swings is reduced.

  The pulley 700, the second support frame 200, and the convex portion 300 are all supported coaxially and rotatably on the first support frame 100. The second support frame 200 and the convex portion 300 are supported by the pulley 700. It can swing back and forth with respect to the first support frame 100.
