[0026] Please refer to Figures 1 to 7 , which shows a preferred embodiment of the present utility model. The fitness device 1 of the present utility model includes a base 10, a counterweight unit 20 and an operation unit 30.
[0027] The base 10 is provided with a seating assembly 11; the counterweight unit 20 is disposed on the base 10 and includes at least one weight block 21; the operation unit 30 includes a connecting rod assembly 31, an operation rod 32 and a buffer 33. The operation rod 32 is located on one side of the seating assembly 11 and is horizontally connected to one end of the connecting rod assembly 31. The counterweight unit 20 is connected to the other end of the connecting rod assembly 31. The buffer 33 is detachably sleeved on the operation rod 32. Wherein, when the buffer 33 is sleeved on the operation rod 32, the buffer 33 can be abutted against the leg of an operator; when the operation rod 32 is not provided with the buffer 33, the operation rod 32 can be held by the operator for use, thereby providing diversified training methods. The buffer 33 is made of soft materials such as foam, rubber, silica gel, cloth, etc., and has good use comfort.
[0028] The base 10 includes a front bottom rod 12, a rear bottom rod 13, and a connecting rod 14 connected between the front bottom rod 12 and the rear bottom rod 13. The riding assembly 11 is disposed on the connecting rod 14. The front bottom rod 12 is eccentrically provided with a vertical rod 15 relative to the connecting rod 14. The counterweight unit 20 and the operation unit 30 are disposed on the vertical rod 15. Thereby, a larger operation space can be provided at the front side of the riding assembly 11, which is convenient for operation. And when in use, the weight of the operator is offset from that of the counterweight unit 20, with good stability and safe operation. Preferably, the base 10 further includes a support rod 16 disposed on the connecting rod 14 and a reinforcing rod 17. The riding assembly 11 is disposed on the support rod 16. The reinforcing rod 17 is bent to connect the vertical rod 15 and the support rod 16, which helps to increase the structural stability and has good bearing capacity and structural strength.
[0029] Specifically, the connecting rod assembly 31 includes a first rod 311 and a second rod 312. The first rod 311 is rotatably connected to the counterweight unit 20 synchronously. The second rod 312 is pivotally connected to the first rod 311 so as to be rotatable about a first rotation axis R1. The operating rod 32 is connected to the second rod 312. The operation unit 30 further includes a first positioning mechanism 34 disposed between the first rod 311 and the second rod 312. The first positioning mechanism 34 can position the second rod 312 relative to the first rod 311 at a first position or a second position. When the second rod 312 is at the first position, the operating rod 32 is lower than a seat portion 111 of the riding assembly 11 and can be operated by the legs of the operator. As Figure 1 shown, the operator can push the operating rod 32 with the legs to move it away from the riding assembly 11. When the second rod 312 is at the second position, the operating rod 32 is higher than the seat portion 111 and can be operated by the hands of the operator. As Figures 5 to 7 shown, the operator can push the operating rod 32 with the hands to move it closer to the riding assembly 11.
[0030] In this embodiment, the first positioning mechanism 34 includes a first positioning wheel 341 and a first braking assembly 342. The first positioning wheel 341 is fixedly disposed on the first rod 311 and cannot rotate relative thereto, and includes a plurality of first locking holes 343 distributed around the first rotation axis R1. The first braking assembly 342 is disposed on the second rod 312 and can be operated and engaged with one of the first locking holes 343, thereby fixing the relative position of the second rod 312 in the circumferential direction of the first rod 311 in a pivotal direction of the second rod 312, so that the second rod 312 cannot rotate relative to the first rod 311. With reference to Figure 3 and Figure 4, the first braking assembly 342 includes a brake lever 344, a mounting cylinder portion 345, and an elastic member 346. The mounting cylinder portion 345 includes a cylinder body 345a fixedly passing through the second rod 312 and a cap 345b screwed to the cylinder body 345a. The brake lever 344 passes through the mounting cylinder portion 345. The elastic member 346 elastically abuts between the brake lever 344 and the cap 345b parallel to the first rotation axis R1, so that the brake lever 344 has a tendency to move toward the side of the first positioning wheel 341. The structure is simple and convenient for assembly. By pulling the brake lever 344 to compress the elastic member 346, the position of the second rod 312 can be adjusted, and the clamping is stable and convenient for operation.
[0031] Furthermore, the operating rod 32 is pivotally connected to the second rod 312 so as to be rotatable about a second rotation axis R2. The operating unit 30 further includes a second positioning mechanism 35 disposed between the second rod 312 and the operating rod 32. The second rotation axis R2 is parallel to the first rotation axis R1. The second positioning mechanism 35 includes a second positioning wheel 351 and a second braking assembly 352. The second positioning wheel 351 is non-rotatably fixed to the operating rod 32 and includes a plurality of second locking holes 353 distributed around the second rotation axis R2. The second braking assembly 352 is disposed on the second rod 312 and can be operated and clamped in one of the second locking holes 353. Thus, according to the needs of the operator, such as the desired operation mode, the arm length and leg length of the operator, etc., the position of the operating rod 32 relative to the second rod 312 can be adjusted. The structure of the second braking assembly 352 is the same as that of the first braking assembly 342, and will not be elaborated here.
[0032] Preferably, the operating rod 32 includes a first extension section 321 and a second extension section 322 connected to one side of the first extension section 321. The first extension section 321 extends parallel to the second rotation axis R2. The second extension section 322 extends perpendicular to the first extension section 321 and is pivotally connected to the second rod 312. The first extension section 321 has a circular cross-sectional profile, and the second extension section 322 has a rectangular cross-sectional profile, with good structural strength. The diameter of the operating rod 32 (i.e., the first extension section 321 of this embodiment) is between 10 mm and 70 mm, and the diameter of the operating rod 32 with better holding comfort is between 25 mm and 50 mm. Thereby, the operator can sit on the seat portion 111 and manually hold the operating rod 32 and reciprocally push it in the centripetal and centrifugal directions, as Figure 8As shown, it is used for training the arms or shoulders and back; the operator can also stand on the side of the operating rod 32 different from the riding component 11 and manually push the operating rod 32 to pivot up and down reciprocally around the first rotation axis R1, so as to achieve different training effects; preferably, the outer peripheral surface of the operating rod 32 is provided with a plurality of convex ribs 323 spaced from each other, which can provide frictional resistance to prevent the buffer 33 from falling off, and the operator can also hold it stably.
[0033] The operating unit 30 further includes at least one set 36. Each set 36 includes a holding part 361 for the operator to hold and a socket part 362 connected to the holding part 361. The socket part 362 is for sleeving on the operating rod 32. The operator can pull the operating rod 32 toward the side close to the riding component 11 through the at least one set 36, as Figure 6 and Figure 7 shown, so as to achieve the exercise of muscle groups such as the arms, shoulders and back, and it is convenient for disassembly and assembly. Preferably, the holding part 361 includes a rigid cylinder 361a (such as but not limited to metal or plastic material), and the socket part 362 includes a belt body 362a penetrating through the rigid cylinder 361a. The structure is simple and easy to manufacture. The operator can hold it stably and the direction of force application is not limited; the operating rod 32 is provided with at least one groove 324, and the at least one set 36 can be clamped in the at least one groove 324, and it is not easy to displace relatively during operation, which is beneficial to stable operation.
[0034] The fitness device 1 further includes a pressing mechanism 40. The pressing mechanism 40 includes a pressing rod 41, a first clamping part 42 and a second clamping part 43. The first clamping part 42 and the second clamping part 43 are arranged on the base 10 and on the different sides of the riding component 11. The pressing rod 41 is detachably arranged on one of the first clamping part 42 and the second clamping part 43; when the pressing rod 41 is arranged on the first clamping part 42, an abutting part 411 of the pressing rod 41 extends parallel to the operating rod 32 and can be abutted by the leg or hand of the operator, as Figure 6 and Figure 7 shown. In this embodiment, the first clamping part 42 is arranged on the front side of the seat part 111, and the pressing rod 41 is height-adjustably arranged on the first clamping part 42, so that the height of the abutting part 411 can be adjusted according to the operation requirements; the second clamping part 43 is arranged on the side of the reinforcing rod 17 relatively far from the seat part 111, which is convenient for placing the pressing rod 41 and can also avoid interfering with the operator.
[0035] The above is the preferred embodiment of the present invention and the technical principles applied. For those skilled in the art, any obvious changes such as equivalent transformation and simple replacement based on the technical solution of the present invention without departing from the spirit and scope of the present invention shall fall within the protection scope of the present invention.
