Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a stair climber with adjustable intensity. Background Technology

[0002] Stair climbers now allow fitness enthusiasts to repeatedly climb stairs, which can enhance the function of the cardiovascular system and fully exercise the thigh and calf muscles.

[0003] The existing stair climber consists of a support frame, a first pedal, a second pedal, an elastic rope, and a steel wire rope. The first and second pedals are slidably connected on the support frame, which is equipped with a first and second rope winding component. The steel wire rope is connected to the first and second pedals through the first rope winding component, and the elastic rope is connected to the first and second pedals through the first rope winding component. During exercise, the elastic rope applies resistance to the first and second pedals. However, this type of stair climber cannot increase or decrease the resistance between the first and second pedals, and cannot change the exercise intensity, making it difficult for different groups of people to adapt to the exercise. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes an adjustable-intensity stair climber, which solves the problem that stair climbers cannot change the intensity of exercise, making it difficult for different groups of people to adapt to the exercise.

[0005] The technical solution adopted by this utility model is as follows: an adjustable-force stair climber, including a support frame, a first pedal, and a second pedal. The support frame is provided with a first slide rail and a second slide rail. A first connecting member is connected to the first pedal, and a second connecting member is connected to the second pedal. The first connecting member is slidably connected to the first slide rail, and the second connecting member is slidably connected to the second slide rail. A steel wire rope is connected between the first connecting member and the second connecting member. The support frame is provided with a first rope winding member, and the steel wire rope passes through the first rope winding member. The first rope winding member is always located above the end of the steel wire rope. At least two elastic ropes are provided between the first connecting member and the second connecting member. A second rope winding member is connected to the first connecting member and the second connecting member. The second rope winding member is always located above the end of the corresponding elastic rope. The elastic rope is detachably connected to the first connecting member and the second connecting member.

[0006] With the above technical solution, when the user exercises, they slide the first and second pedals in opposite directions. When the second rope-winding component on the first connector moves away from the second rope-winding component on the second connector, the elastic rope stretches, increasing the movement resistance of the first and second pedals. When the second rope-winding component on the first connector moves closer to the second rope-winding component on the second connector, the elastic rope shortens, increasing the movement resistance of the first and second pedals. The number of elastic ropes can be detached or installed to change. The more elastic ropes there are, the more effort the user needs to exert during exercise, and the more obvious the exercise effect. This utility model can freely change the number of elastic ropes, making it convenient to adjust the resistance on the first and second pedals, and can change the exercise intensity. It is more convenient and easier for users to adapt to.

[0007] Furthermore, a bolt is connected to the elastic rope, a first mounting hole is provided on the first connecting member, a second mounting hole is provided on the second connecting member, and the bolt is detachably connected to the first mounting hole and the second mounting hole.

[0008] Through the above technical solution, the elastic rope is connected or disconnected from the first mounting hole and the second mounting hole by bolts, so that the elastic rope can be installed or disconnected from the first connector and the second connector. The installation and removal of the elastic rope is simple and convenient, and the connection effect between the elastic rope and the first connector and the second connector is better.

[0009] Furthermore, one of the elastic ropes passes through the second winding member on the first connector and the second winding member on the second connector. The elastic rope has a first end and a second end. The first end is close to the first connector, and the second end is close to the second connector. The portion of the elastic rope from the first end to the nearest second winding member is a first segment, the portion of the elastic rope from the second end to the nearest second winding member is a second segment, and the portion between the first segment and the second segment is a third segment. The first segments on each elastic rope are parallel, the second segments on each elastic rope are parallel, and the third segments on each elastic rope are parallel.

[0010] With the above technical solution, the first segment of each elastic rope is parallel, the second segment of each elastic rope is parallel, and the third segment of each elastic rope is parallel. During exercise, the resistance encountered when the first and second pedals slide can be increased or decreased smoothly, making the exercise smoother for the user.

[0011] Furthermore, the first connector is provided with a first separator, and the second connector is provided with a second separator, with the first separator and the second separator located between two adjacent third segments.

[0012] Through the above technical solution, the first separator and the second separator separate adjacent elastic ropes, preventing adjacent elastic ropes from getting close and causing interference, and limiting the elastic ropes.

[0013] Furthermore, the spatial plane in which all the second rope winding members are located is parallel to the first slide rail; or, the spatial plane in which all the second rope winding members are located is parallel to the second slide rail.

[0014] With the above technical solution, the spatial plane where the second rope winding component is located is parallel to the first slide rail or parallel to the second slide rail, so that the connection between the elastic rope and the rope winding component is better when the user uses it.

[0015] Furthermore, when the first connector and the second connector are at the same height, the second rope winding member on the first connector and the second rope winding member on the second connector are symmetrical.

[0016] With the above technical solution, when the first connector and the second connector are at the same height, the second rope winding component on the first connector and the second rope winding component on the second connector are symmetrical, making it easier and more convenient for the user to use.

[0017] Furthermore, the first pedal is provided with a first connecting plate, which is rotatably connected to the first connecting member. The first connecting member is provided with a first snap-fit ​​hole, and the first connecting plate is provided with a plurality of first adjustment holes. The second pedal is provided with a second connecting plate, which is rotatably connected to the second connecting member. The second connecting member is provided with a second snap-fit ​​hole, and the second connecting plate is provided with a plurality of second adjustment holes. It also includes a first pin and a second pin. The first pin is detachably connected to the first snap-fit ​​hole and the first adjustment hole, and the second pin is detachably connected to the second snap-fit ​​hole and the second adjustment hole.

[0018] Through the above technical solution, the first pin is detachably connected to the first snap-fit ​​hole and the first adjustment hole, and the second pin is detachably connected to the second snap-fit ​​hole and the second adjustment hole. Adjusting the installation of the first pin and the first snap-fit ​​hole can change the angle between the first pedal and the first connecting member, and adjusting the installation of the second pin and the second snap-fit ​​hole can change the angle between the second pedal and the second connecting member, which is convenient for the user.

The elastic rope 8 is detachably connected to the first connector 4 and the second connector 5.

[0031] When the user exercises, the first pedal 2 and the second pedal 3 slide in opposite directions. When the second rope winding member 9 on the first connecting member 4 and the second rope winding member 9 on the second connecting member 5 move away from each other, the elastic rope 8 stretches, increasing the movement resistance of the first pedal 2 and the second pedal 3. When the second rope winding member 9 on the first connecting member 4 and the second rope winding member 9 on the second connecting member 5 move closer together, the elastic rope 8 shortens, increasing the movement resistance of the first pedal 2 and the second pedal 3. The number of elastic ropes 8 can be disassembled or installed to change. The more elastic ropes 8 there are, the more force the user needs to exert during exercise, and the more obvious the exercise effect. This utility model can freely change the number of elastic ropes 8, making it convenient to adjust the resistance on the first pedal 2 and the second pedal 3, and can change the exercise intensity. It is more convenient for users to use and easier to adapt to.
