[0002] With the improvement of people's living standards, people are paying more and more attention to fitness, using it for body shaping or adjusting cardiopulmonary respiration. Existing technology includes a stair climber, which mainly consists of two support frames connected at the top, extending at a certain angle. One support frame has two sets of foot pedals, with a traction rope passing around a traction sheave on the support frame between them. The other support frame has handrails. In use, the user holds the handrails and places their feet on the two sets of foot pedals, causing them to slide up and down the support frame alternately, simulating stair climbing. This effectively increases heart rate and promotes fat burning. However, existing stair climbers lack additional damping during use, limiting their effectiveness and thus requiring further improvement. Utility Model Content

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1 to 3 As shown, this embodiment provides a stair climber with an elastic resistance rope between two sets of foot pedal assemblies, including:

[0034] The support device includes a first support frame 1 and a second support frame 2. The upper ends of the first support frame 1 and the second support frame 2 are connected. The lower ends of the first support frame 1 and the second support frame 2 are far apart from each other and both are used to support the ground. The second support frame 2 is provided with an upwardly extending handrail 21 for easy user operation. The first support frame 1 is provided with a traction rope wheel 13. Specifically, there are two traction rope wheels 13, which are arranged side by side.

[0035] The left and right sets of foot pedal assemblies are slidably mounted on the first support frame 1 in a vertical direction. Specifically, the first support frame 1 is set at a certain slope, allowing the left and right sets of foot pedal assemblies to slide vertically along the first support frame 1. A traction rope 4 is provided between the two sets of foot pedal assemblies, passing around the traction rope wheel 13. Each set of foot pedal assemblies is equipped with a resistance rope wheel 14.

[0036] An elastic resistance rope 3 is disposed between the two sets of pedal assemblies, and the elastic resistance rope 3 passes around the resistance rope pulleys 14 on the two sets of pedal assemblies. The elastic resistance rope 3 passes around the two resistance rope pulleys 14, thereby forming a rotating connection, which not only further reduces friction and extends the service life of the rope, but also prevents the elastic resistance rope 3 from getting tangled.

[0037] In this embodiment, as Figure 2 and Figure 3 As shown, to further secure the elastic resistance rope 3, both ends of the elastic resistance rope 3 are provided with connecting ends, and each set of pedal assemblies is provided with a rope connecting part. The elastic resistance rope 3 passes around the resistance rope pulleys 14 on the two sets of pedal assemblies, and the two connecting ends are respectively connected to the two rope connecting parts one by one. Each rope connecting part is located on the upper side of its corresponding resistance rope pulley 14, specifically on the upper side along the sliding direction of the pedal assembly.

[0038] In this embodiment, as Figure 2 and Figure 3As shown, for ease of assembly, both rope connection parts are fixed pins 15, which extend in the left-right direction. Each connection end is provided with a first collar 31, which is respectively fitted onto the two fixed pins 15. Each fixed pin 15 is provided with a fastener to prevent the first collar 31 from axially disengaging from the fixed pin 15. The fastener can be a bolt, etc.

[0039] In this embodiment, for ease of assembly, both ends of the traction rope 4 are provided with second loops. The traction rope 4 passes around the traction rope wheel 13, and the two second loops are respectively fitted onto the two fixing pins 15. Specifically, the two first loops are located between the two second loops. During connection, the second loops at both ends of the traction rope 4 can be connected to the two rope connection parts respectively, and then the two first loops 31 of the elastic resistance rope 3 can be connected to the two fixing pins 15 respectively. The traction rope 4 and the elastic resistance rope 3 share fixing pins, thus simplifying assembly. Alternatively, the two second loops can be located between the two first loops 31.

[0040] In this embodiment, as Figure 2 and Figure 3 As shown, as a specific structure of the pedal assembly, each set of the pedal assembly includes a sliding seat 12 slidably connected to the first support frame 1 and a pedal 11 disposed on the sliding seat 12; when in use, the user steps on the two pedals 11 with both feet respectively.

[0041] Both the rope connection portion and the resistance rope pulley 14 are disposed on the sliding seat 12. Preferably, the rope connection portion and the resistance rope pulley 14 on each sliding seat 12 are disposed on the same side of that sliding seat 12. Specifically, the rope connection portion and the resistance rope pulley 14 on the pedal assembly located on the left side of the first support frame 1 are located on the right side of their sliding seat 12, and the rope connection portion and the resistance rope pulley 14 on the pedal assembly located on the right side of the first support frame 1 are located on the left side of their sliding seat 12, thereby facilitating the winding of the elastic resistance rope 3.

[0042] In this embodiment, as Figure 2 and Figure 3 As shown, as a specific structure of the resistance rope pulley 14, each resistance rope pulley 14 includes a wheel bracket 141 fixedly connected to the pedal assembly and a wheel body 142 rotatably mounted on the wheel bracket 141, with the elastic resistance rope 3 passing around the wheel body 142. Specifically, the wheel body 142 is provided with a rope winding groove, and the elastic resistance rope 3 passes around the rope winding groove.

[0043] In this embodiment, the elastic resistance rope 3 can also be configured as a closed loop.

[0044] Working principle explanation:

[0045] When using the stair climber, as the user drives the two sets of foot pedals to alternately tilt and slide up and down along the first support frame 1, the elastic resistance rope 3 provides a certain damping effect during the stretching process. This forces the user to overcome resistance and achieve better fitness results. Simultaneously, the elastic resistance rope 3 forms a rotating connection by wrapping around the resistance rope wheel 14, reducing friction between the elastic resistance rope 3 and the resistance rope wheel 14, increasing its service life, and preventing the elastic resistance rope 3 from tangling or knotting.

[0046] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
