Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to a stair climbing machine. Background Technology

[0002] Currently, some stair-climbing machines are available on the market that simulate stair-climbing motions. These machines typically consist of a first and second support frame arranged in an A-shape. The first support frame has two sets of pedal assemblies, connected by a traction rope that loops around a rope wheel. For ease of operation, a handrail usually extends upwards from the second support frame. In use, the user places their feet on the two sets of pedal assemblies and holds the handrail, causing the pedal assemblies to alternately tilt and slide back and forth, simulating the action of climbing stairs, thus providing great convenience. However, in existing stair-climbing machines, the handrail frame is usually integrally formed or fixedly connected to the second support frame. When the first and second supports are folded, the non-foldable handrail frame results in the overall machine remaining bulky and inconvenient to store. Summary of the Invention

[0003] This utility model provides a stair climber, which aims to solve the problem that existing stair climbers are inconvenient to store because the handrails cannot be folded, resulting in a large size after folding.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A stair-climbing machine includes:

[0006] A support assembly includes a first bracket and a second bracket. The lower ends of the first bracket and the second bracket are spaced apart from each other and both are used to support the ground. The upper end of the second bracket is rotatably connected to the upper end of the first bracket via a first pivot. A first locking assembly is provided between the second bracket and the first bracket to lock the first bracket and the second bracket in the use state. The first bracket is provided with two left and right guide frames. When the first bracket is in use, both guide frames are gradually tilted upwards from back to front. The first bracket is also provided with a rope winding wheel assembly.

[0007] Two sets of pedal assemblies are slidably mounted on the two guide frames, and a traction rope, which passes around the rope winding wheel assembly, connects the two sets of pedal assemblies; and...

[0008] The handrail frame has its lower end rotatably connected to the support assembly via a second pivot, and a second locking assembly is provided between the handrail frame and the support assembly to lock the handrail frame in the use state.

[0009] When the first locking component releases its lock on the second support and the first support, and the second locking component releases its lock on the handrail and the support component, the stair climber can be switched from the use state to the folded state by folding the handrail and the second support toward the first support.

[0010] A further embodiment: Each of the guide frames is provided with an upper connecting part at its upper end; the two ends of the first rotating shaft and the second rotating shaft are respectively connected to the two upper connecting parts;

[0011] The handrail frame includes two first handrails, left and right, and each first handrail is provided with a set of second locking components between itself and the upper connecting part on its corresponding side;

[0012] The second bracket includes two second support rods on the left and right, and each second support rod is provided with a set of the first locking components between itself and the upper connecting part on its corresponding side.

[0013] Based on the above technical solution: the above settings enable the two sets of second locking components to lock the handrail and the first support when the stair climber is in use, and the two sets of first locking components to lock the second support and the first support, thereby improving the stability of the entire stair climber.

[0014] A further embodiment: the first locking component includes a first locking pin detachably disposed between the upper connecting portion and the corresponding second support rod.

[0015] Based on the above technical solution: the above setting facilitates quick and easy disassembly and assembly of the first locking pin, thereby allowing the second bracket to be switched to the use state or the folded state.

[0016] A further solution: The second locking component includes a U-shaped frame, a first locking pin, and a second locking pin. The first locking pin is detachably inserted between the two arms of the corresponding U-shaped frame, the second support rod, and the upper connecting part. The second locking pin is detachably inserted between the two arms of the corresponding U-shaped frame, the upper connecting part, and the first handrail.

[0017] When the stair climber is in use, the U-shaped frame is fitted over the outside of the corresponding upper connecting part, and the opening of the U-shaped frame faces forward.

[0018] Based on the above technical solution: by setting the U-shaped frame to be fitted on the outside of the corresponding upper connecting part in the use state, the stability of the handrail frame is improved in the use state; by setting the first locking component and the second locking component to share the first locking pin, the entire stair climber is easier to disassemble and assemble when switching to the use state or the folded state.

[0019] A further solution: Each set of pedal assemblies is provided with at least one elastic rope between itself and the first bracket;

[0020] Alternatively, at least one elastic cord may be provided between the two sets of pedal assemblies.

[0021] Based on the above technical solution: the elastic rope is used to provide a certain elastic resistance when the pedal assembly slides along the guide frame, so that the user can achieve better fitness results.

[0022] A further embodiment: when at least one elastic rope is provided between each set of pedal assemblies and the first bracket, the first bracket further includes an elastic rope connecting frame located between the two guide frames, and the elastic rope connecting frame is located on the rear side of the pedal assembly;

[0023] The elastic rope connecting frame is provided with a plurality of first connecting parts, and each set of pedal assemblies is provided with at least one second connecting part. Both ends of each elastic rope are respectively connected to the corresponding first connecting part and second connecting part.

[0024] Based on the above technical solution: by setting up an elastic rope connecting frame, it is convenient to install the elastic rope. When there are multiple second connecting parts, users can adjust the resistance according to their own needs by increasing or decreasing the number of elastic ropes.

[0025] A further solution: When the stair climber switches from the working state to the folded state, the second support is located between the first support and the handrail.

[0026] Based on the above technical solution: the above settings make it not only smaller in size when folded, but also easier to store.

[0027] A further solution: A lower connecting part is provided on the lower side near the lower end of each of the guide frames. The lower connecting part has a groove with the slot facing downward. The handrail frame includes two first handrails on the left and right. When the stair climber is switched from the use state to the folded state, the two first handrails are respectively located in the two grooves.

[0028] Based on the above technical solution: the above settings enable the two first handrails to be locked in the groove when the stair climber is switched to the folded state, thus making it more stable in the folded state and easier to store.

[0029] A further embodiment: The first support also includes a bottom support connected between the lower ends of the two guide frames, and the upper end of the handrail is provided with a hand grip. When the stair climber is switched from the use state to the folded state, the hand grip is located between the bottom support and the two lower connecting parts.

[0030] Based on the above technical solution, the above settings make the stair climber more stable when folded.

[0031] A further embodiment: The pedal assembly includes a sliding seat and a foot pedal disposed on the sliding seat. The sliding seat is slidably disposed on the guide frame corresponding to it. The two ends of the traction rope are respectively connected to two sliding seats. The front end of each foot pedal is rotatably connected to its corresponding sliding seat through a third rotating shaft. Each foot pedal is provided with a plurality of first positioning holes arranged around the third rotating shaft. The sliding seat is provided with a second positioning hole and a positioning pin. The positioning pin adjusts and locks the tilt angle of the foot pedal relative to the sliding seat by cooperating with the second positioning hole and the first positioning hole at different positions.

[0032] Based on the above technical solution: the above settings allow users to adjust the tilt angle of the foot pedal relative to the sliding seat according to their own needs, and when the stair climber is switched to the folded state, the tilt angle of the foot pedal relative to the sliding seat can be adjusted to the minimum, thus facilitating overall storage.

[0033] The beneficial effects of this utility model are as follows:

[0034] This invention improves the stability of the stair climber in use by rotatably connecting the upper end of the second support to the upper end of the first support and by setting a first locking component to lock the second support in the use state. It also rotatably connects the lower end of the handrail to the first support and sets a second locking component between them to lock the handrail in the use state. When switched to the folding state, the handrail and the second support fold towards the first support, further reducing the size of the stair climber after folding, making it easier to store and transport.

Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0044] like Figure 1 and Figure 5 As shown, this embodiment provides a stair-climbing machine, including:

[0045] The support assembly includes a first bracket 1 and a second bracket 2. The lower ends of the first bracket 1 and the second bracket 2 are far apart from each other in use and are both used to support the ground. The upper end of the second bracket 2 is rotatably connected to the upper end of the first bracket 1 via a first rotating shaft 16. A first locking component is provided between the second bracket 2 and the first bracket 1 to lock the first bracket 1 and the second bracket 2 in use. The first bracket 1 is provided with two left and right guide frames 11. When the first bracket 1 is in use, the two guide frames 11 are gradually tilted upward from back to front. The first bracket 1 is also provided with a rope winding wheel assembly 14.

[0046] Two sets of pedal assemblies 7 are slidably mounted on the two guide frames 11 respectively, and a traction rope 15, which passes around the rope wheel assembly 14, connects the two sets of pedal assemblies 7; and,

[0047] The handrail 3 has its lower end rotatably connected to the support assembly via a second rotating shaft 17, and a second locking component is provided between the handrail 3 and the support assembly to lock the handrail 3 in the use state.

[0048] When the first locking component releases the lock on the second bracket 2 and the first bracket 1, and the second locking component releases the lock on the handrail 3 and the support component, the stair climber can be switched from the use state to the folded state by folding the handrail 3 and the second bracket 2 toward the first bracket 1. When switched to the folded state, the size of the entire stair climber is further reduced, making it easier to store.

[0049] In some specific implementations, such as Figure 1 , Figure 3 and Figure 5 As shown, each of the guide frames 11 has an upper connecting part 111 at its upper end; the two ends of the first rotating shaft 16 and the second rotating shaft 17 are respectively connected to the two upper connecting parts 111.

[0050] The handrail frame 3 includes two first handrails 32 on the left and right, and each first handrail 32 is provided with a set of second locking components between it and the upper connecting part 111 on its corresponding side;

[0051] The second bracket 2 includes two second support rods 21 on the left and right, and each second support rod 21 is provided with a set of the first locking components between it and the upper connecting part 111 on its corresponding side.

[0052] Each guide frame 11 includes two left and right clamping frames 113 and a guide rail 114 located between the two clamping frames 113. The pedal assembly 7 is slidably connected to the guide rail 114. The upper connecting part 111 is specifically a connecting groove between the two clamping frames 113, and the first handrail 32 and the second support rod 21 are both located in the corresponding connecting groove.

[0053] In some specific implementations, such as Figure 1 , Figure 3 and Figure 5 As shown, in order to facilitate quick assembly and disassembly, the first locking component includes a first locking pin 41 that is detachably disposed between the upper connecting part 111 and the corresponding second support rod 21.

[0054] The second locking assembly includes a U-shaped frame 52, a first locking pin 41 and a second locking pin 51. The first locking pin 41 is detachably inserted between the two arms of the corresponding U-shaped frame 52, the second support rod 21 and the upper connecting part 111. The second locking pin 51 is detachably inserted between the two arms of the corresponding U-shaped frame 52, the upper connecting part 111 and the first handrail 32.

[0055] When the stair climber is in use, the U-shaped frame 52 is sleeved on the outside of the corresponding upper connecting part 111, with the opening of the U-shaped frame 52 facing forward. Specifically, the U-shaped frame 52 is sleeved on the upper end of the two clamping frames 113, and the closed part of the U-shaped frame 52 is locked between the upper end of the guide rail 114 and the two clamping frames 113. The first locking pin 41 and the second locking pin 51 are specifically bolts and nuts.

[0056] In some specific implementations, such as Figure 1 , Figure 2 and Figure 5 As shown, in order to enable users to achieve better fitness results, each set of pedal assembly 7 is provided with at least one elastic rope 6 between it and the first support 1.

[0057] Alternatively, the elastic cord 6 can be configured such that at least one elastic cord 6 is provided between the two sets of pedal assemblies 7.

[0058] As a specific structure, such as Figure 1 , Figure 2 and Figure 5 As shown, when at least one elastic rope 6 is provided between each set of pedal assemblies 7 and the first bracket 1, the first bracket 1 also includes an elastic rope connecting frame 12 located between the two guide frames 11, and the elastic rope connecting frame 12 is located on the rear side of the pedal assembly 7; the elastic rope connecting frame 12 is specifically fixedly connected to the two guide frames 11.

[0059] The elastic rope connecting frame 12 is provided with a plurality of first connecting parts 121, and each set of pedal assemblies 7 is provided with at least one second connecting part 723. Both ends of each elastic rope 6 are connected to the corresponding first connecting part 121 and second connecting part 723, respectively. When there are multiple second connecting parts 723, the user can adjust the resistance according to their needs by increasing or decreasing the number of elastic ropes 6. Specifically, the first connecting part 121 and the second connecting part 723 are slots used to hold the ends of the elastic ropes 6.

[0060] In some specific implementations, such as Figure 5As shown, to improve the stability of the stair climber in the folded state, when the stair climber switches from the active state to the folded state, the second support 2 is located between the first support 1 and the handrail frame 3. Specifically, it can be configured such that the second support 2 is sandwiched between the first support 1 and the handrail frame 3.

[0061] Each guide frame 11 has a lower connecting part 112 located on its lower side near the bottom end. The lower connecting part 112 has a groove with its opening facing downwards. Specifically, the groove is formed between two clamping frames. The handrail frame 3 includes two first handrails 32 on the left and right. When the stair climber switches from its active state to its folded state, the two first handrails 32 are respectively located within the two grooves. Specifically, the two first handrails 32 can be configured to be locked within the two grooves. This provides greater stability in the folded state and facilitates storage.

[0062] The first support 1 also includes a bottom support 13 connected between the lower ends of the two guide frames 11. The upper end of the handrail frame 3 is provided with a handgrip 31. When the stair climber is switched from its active state to its folded state, the handgrip 31 is located between the bottom support 13 and the two lower connecting parts 112. Specifically, the handgrip 31 includes two curved handgrip rods 311. The bottom support 13 has two mounting slots 131, with the lower ends of the two guide frames 11 respectively located within the two mounting slots 131. The bottom support 13 also has two fixing parts 132, with the lower ends of the two guide frames 11 respectively fixedly connected to the two fixing parts 132 by screws or the like. The bottom support 13 is supported on the ground, providing better stability.

[0063] In some specific implementations, such as Figure 1 , Figure 2 and Figure 5 As shown, the pedal assembly 7 includes a sliding seat 72 and a foot pedal 71 disposed on the sliding seat 72. The sliding seat 72 is slidably disposed on the corresponding guide frame 11. The two ends of the traction rope 15 are respectively connected to the two sliding seats 72. The rope winding wheel assembly 14 includes two rope winding wheels, which are respectively disposed on the two guide frames 11. The front end of each foot pedal 71 is rotatably connected to its corresponding sliding seat 72 via a third rotating shaft 73. Each foot pedal 71 is provided with a plurality of first positioning holes 711 arranged around the third rotating shaft 73. The sliding seat 72 is provided with a second positioning hole 721 and a positioning pin 722. The positioning pin 722 adjusts and locks the tilt angle of the foot pedal 71 relative to the sliding seat 72 by cooperating with the second positioning hole 721 and the first positioning holes 711 at different positions.

[0064] The working principle will be explained further below:

[0065] In use, the user places both feet on the two sets of pedal assemblies 7 and grips the two handrails 311, causing the two sets of pedal assemblies 7 to slide back and forth alternately at a certain incline, simulating the action of climbing stairs. When switching to the folded state, the tilt angle of the foot pedals 71 relative to the sliding seat 72 is adjusted to the minimum, and by removing the first locking pin 41 and the second locking pin 51, the handrail frame 3 and the second support 2 are both folded towards the first support 1. After folding, the volume is smaller, and after folding, the second support 2 is clamped between the handrail frame 3 and the first support 1, thus improving stability.

[0066] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
