[0002] In the modern fitness field, stair-climbing equipment has gained widespread attention and popularity due to its ability to effectively simulate climbing movements. The core of this type of equipment lies in the user's alternating application of force with both feet onto specially designed pedals, causing the pedals to move up and down along a track, thus achieving a similar exercise experience to climbing stairs. To ensure smoothness and coordination of the movement, a specially designed linkage mechanism is usually installed between the two pedals.

[0003] However, existing fitness equipment still has certain problems, especially in terms of resistance adjustment. Some equipment lacks an effective resistance adjustment mechanism, which means that users can only exercise under fixed resistance conditions and cannot flexibly adjust it according to their physical condition or training needs.

[0004] In addition, although some devices offer resistance adjustment functions, their operation is complicated and inconvenient, which limits the user experience and practical application effect.

[0005] In view of this, the inventor specifically designed a fitness device that simulates climbing stairs, and this case arises from this invention. Utility Model Content

[0036] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] Please see Figures 1 to 8 This is a fitness device simulating stair climbing, which is the preferred embodiment of the present invention. It includes a frame 10, a pedal assembly 20, a linkage mechanism 30, a damping mechanism 40, and a resistance adjustment mechanism 50, as detailed below:

[0038] like Figure 1 , 2 As shown, the frame 10 includes two parallel and spaced slide rails 11 and a handrail support frame 12. The handrail support frame 12 and the slide rails 11 are connected in a herringbone shape. Specifically, the upper ends of the two parallel slide rails 11 are connected to the same upper connecting rod 13 and the lower ends are connected to the same bottom rod 14. The handrail support frame 12 includes two uprights 121 and a support 122 connecting the bottom of the two uprights 121. One of the uprights 121 is fixed at each end of the upper connecting rod 13, so that the handrail support frame 12 and the slide rails 11 form an inclined herringbone structure.

[0039] In addition, the tops of the two uprights 121 are symmetrical and bend towards each other to form handrails 123 for users to grip. Foam 124 is sleeved on the outside of the handrails 123 to provide a comfortable grip and improve the user experience.

[0040] The upper connecting rod 13 has a device bracket 15 in the middle. The device bracket 15 is equipped with a corresponding clamping structure or support structure for clamping or fixing the corresponding electronic equipment, providing motion data or playing audio and video materials to assist users in their movements.

[0041] like Figure 1 , 2 As shown, the pedal assembly 20 has two pedals that are slidably mounted along two slide rails 11 to provide the user with the correct foot position.

[0042] In this embodiment, the pedal assembly 20 includes a sliding seat 21 and a foot pedal 22. The sliding seat 21 and the slide rail 11 are guided and slid by a roller structure 23 clamped on both sides. The foot pedal 22 is fixedly connected to both sides of the sliding seat 21 by two extending fixing plates 24 at the bottom. There is a pivot point 25 between the fixing plate 24 and the sliding seat 21 that allows the foot pedal 22 to rotate and another fixing point 26 that limits the rotation angle of the foot pedal 22. The fixing plate 24 has several adjustable fixing holes (not shown in the figure). By fixing any one of the fixing holes to the side wall of the sliding seat 21, the angle of the foot pedal 22 can be fixed, so that the user can change the swing angle of the foot pedal 22 according to his / her own needs and obtain the best stepping experience.

[0043] like Figure 2 , 3 As shown, the linkage mechanism 30 is used to drive the two pedals to slide synchronously in opposite directions along the two slide rails 11 in accordance with the user's foot movements.

[0044] In this embodiment, the linkage mechanism 30 includes a fixed frame 31, a first guide wheel 32, and a linkage rope 33. The fixed frame 31 is horizontally placed between the upper sides of the two slide rails 11. There are two first guide wheels 32, which are respectively located on both sides of the fixed frame 31. One end of the linkage rope 33 is fixed to one of the pedal assemblies 20, and the other end passes through the first guide wheel 32 on the same side and the first guide wheel 32 on the other side in sequence before being fixed to the other pedal assembly 20. The first guide wheel 32 has a recessed groove around its periphery to form a guide groove that fits into the linkage rope 33 (not shown in the figure).

[0045] The fixing frame 31 has a U-shaped structure, consisting of a square base plate 311 and side plates 312 perpendicularly erected on both sides of the base plate 311 in the width direction. The two sides of the fixing frame 31 in the length direction are welded and fixed between the slide rails 11 and are located near the top of the slide rails, which is the highest position for the pedal assembly 20 to slide. At this time, the U-shaped opening of the fixing frame 31 faces the bottom rod 14 of the slide rails 11 in a direction parallel to the slide rails 11. The first guide wheel 32 is pivotally connected to the inside of the U-shaped opening of the fixing frame 31 through a first pivot 34 passing between the two side plates 312 to achieve control of the first guide wheel 32. The rotation axis of the first guide wheel 32 is perpendicular to the plane where the two slide rails 11 are located. The two first guide wheels 32 are fixed at positions close to the two slide rails 11. The end of the linkage rope 33 is fixed to one of the sliding seats 21, and after passing through one of the guide wheels, it continues to extend along the inner side of the fixing frame 31 to the other guide wheel, and then extends along the other guide wheel to the other sliding seat 21 for fixation. Thus, when the foot pedal 22 is stepped on by the user, it moves synchronously and alternately along the extension direction of the two slide rails 11 under the drive of the linkage rope 33, realizing the simulation process of climbing stairs.

[0046] In addition, such as Figure 2 As shown, a connecting shaft 211 is fixedly protruding from the side of each of the two sliding seats 21 that are close to each other. A connecting buckle 331 is fixedly sleeved at the end of the linkage rope 33. The end of the connecting buckle 331 is plate-shaped and a connecting hole (not shown in the figure) is opened through its plate-shaped surface to fit the connecting shaft 211 with clearance. The end of the connecting shaft 211 is provided with external thread (not shown in the figure). The connecting buckle 331 is threadedly locked onto the connecting shaft 211 by the nut 212, thereby forming a stable connection and detachable design for the two ends of the linkage rope 33. This provides a stable connection point and facilitates subsequent maintenance and replacement.

[0047] Specifically, the insertion position of the linkage rope 33 on the first guide wheel 32 and its fixed position on the connecting shaft 211 on the same side are on the same vertical plane, so that the linkage rope 33 forms a stable connection guide structure between the slide rails 11 and maintains a regular state, which can improve the aesthetics and provide a stable connection structure.

[0048] In order to continue to provide resistance to the alternating movement of the foot pedal assembly in order to thoroughly simulate the movement process of climbing stairs, the specific solution of this embodiment is as follows:

[0049] like Figure 3-6 As shown, the damping mechanism 40 includes a linear elastic element and two guide elements 42. The two guide elements 42 are located on the side of the two pedal assemblies 20 that are close to each other and are used to guide the elastic element. One end of the elastic element is fixed to one side of the bottom of the slide rail 11, and the other end passes through the guide element 42 on the same side and the guide element 42 on the other side in sequence and is then fixed to the other side of the bottom of the slide rail 11.

[0050] In this embodiment, the guide member 42 includes a fixed bracket 421 and a second guide wheel 422. The fixed bracket 421 is U-shaped and fixed to the side wall of the sliding seat 21 on the side where the two pedal assemblies 20 are close to each other. The opening side of the fixed bracket 421 faces the other pedal assembly 20 and the second guide wheel 422 is rotatably connected to the opening side of the fixed bracket 421. The second guide wheel 422 is rotatably connected to the inside of the U-shaped opening of the fixed bracket 421 through a second rotating shaft 423. The rotation axis of the second rotating shaft 423 is parallel to that of the first rotating shaft 34, so that the two second guide wheels 422 can form a connecting guide structure that turns the elastic member along one side of the moving seat toward the other side of the moving seat.

[0051] In this embodiment, the elastic element is an elastic rope 41, or it can be a spring; in this embodiment, it is an elastic rope 41.

[0052] like Figure 4 , 5 As shown, the resistance adjustment mechanism 50 includes an adjustment seat 51 and an adjustment connector 52. The adjustment connector 52 is located at both ends of the elastic member, and the adjustment seat 51 is located at the bottom of the slide rail 11 and has several adjustment holes 511 that are detachably engaged with the adjustment connector 52.

[0053] like Figure 7 As shown, in this embodiment, the adjusting connector 52 includes a sleeve-shaped main body 53 and a hook portion 54 located on one side of the bottom of the main body 53. The main body 53 is detachably fixed to the end of the elastic rope 41, and the hook portion 54 forms a groove 55 that engages with the adjusting hole 511.

[0054] The main body 53 has an axially extending mounting hole 531 with openings at the top and bottom. The top of the main body 53, located at the opening of the mounting hole 531, is recessed to form a rope threading hole 532 that fits with the elastic rope 41 with a clearance. The end of the elastic rope 41 is fixed with a limiting part 411, which limits and stops the rope threading hole 532 to achieve the connection between the elastic rope 41 and the main body 53. The lower end of the mounting hole 531 is a cylindrical lower mounting area, and the upper side of the lower mounting area is a conical upper mounting area (not shown in the figure) with an opening that gradually narrows towards the rope threading hole 532. The limiting part 411 is disc-shaped, and the outer diameter of the limiting part 411 is between the diameter of the sound transmission hole and the inner diameter of the lower mounting area, so that it can be stably engaged in the mounting hole 531, completing the stable connection between the elastic rope 41 and the adjusting joint 52.

[0055] Preferred, such as Figure 7 , 8As shown, the hook 54 extends integrally downward along the bottom of the main body 53 and forms a U-shaped structure with an upward opening. The inner side of the U-shaped structure forms a slot 55. The inside of the adjusting seat 51 forms a hollow inner cavity 512. The adjusting hole 511 is connected to the inner cavity 512 and is rectangular. The wall thickness of the adjusting hole 511 is adapted to the width of the slot 55.

[0056] Preferred, such as Figure 7 As shown, a reinforcing part 56 for strengthening the structure is integrally connected between the hook part 54 and the side wall of the main body 53. The reinforcing part 56 is in the form of a sheet.

[0057] Preferred, such as Figure 5 , 8 As shown, the adjusting seat 51 is arranged parallel to the length of the slide rail 11, and several adjusting holes 511 are distributed on the surface of the adjusting seat 51 along the length of the slide rail 11. In this embodiment, there are three adjusting holes 511, which are evenly distributed on the surface of the adjusting seat 51 along the length of the slide rail 11. When the hook 54 of the adjusting connector 52 is hooked into the adjusting hole 511 at the uppermost end of the adjusting seat 51, the elastic rope 41 is in the most relaxed state, and the corresponding resistance is the smallest. If the user wants to increase the resistance, he / she only needs to hook the hook 54 of the adjusting connector 52 on both sides of the adjusting seat 51 into the two adjusting holes 511 at other opposite positions at the same time to realize the resistance adjustment process, which is convenient and quick.

[0058] The beneficial effects of this utility model are as follows:

[0059] This invention adjusts the tension of the elastic element through the adjusting seat 51 and the adjusting joint 52. It has a simple structure and is easy to adjust. Compared with existing fitness equipment, it can more conveniently adjust the resistance of the pedal assembly 20 according to individual physical condition or training needs.

[0060] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
