Description

Technical Field

[0001] This application relates to the field of sports equipment, and in particular to a stair climber with internal wiring. Background Technology

[0002] A stair climber is a fitness device that simulates climbing stairs. By mimicking the motion of climbing stairs, it helps users exercise their legs, glutes, and core muscles, enhances cardiovascular function, and improves coordination and balance. Due to its efficient exercise effect and relatively small footprint, this equipment is widely used in homes, gyms, and rehabilitation centers, providing a convenient exercise method for people of different ages and physical conditions.

[0003] A stair climber typically consists of a support frame with foot pedals connected by ropes. Users simulate climbing stairs by alternately stepping on the pedals. During use, the up-and-down movement of the pedals moves the connecting ropes, allowing the pedals to be lifted alternately, thus simulating the exercise effect of climbing stairs. In addition, stair climbers are also equipped with assist ropes to help users exercise, reduce leg strain, and improve comfort and safety.

[0004] Specifically, the connecting rope to the foot pedal is usually external, meaning the connecting rope is exposed outside the support frame. During use, the connecting rope moves back and forth, and the gap between the connecting rope and the frame can easily trap the user's fingers or other objects, leading to accidental injury or equipment damage. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned in the background art that the connecting rope of the foot pedal is usually external, that is, the connecting rope is exposed outside the support frame. During use, the connecting rope moves back and forth, and the gap between the connecting rope and the frame can easily trap the user's fingers or other objects, resulting in accidental injury or equipment damage. This application provides a stair climber with internal wiring.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An internally cabled stair climber includes a support rod 1, two symmetrical support rods 2 on one side of the support rod 1, a connecting rod fixed between the two support rods 2, the connecting rod being fixedly connected to the support rod 1, foot pedals on each of the two support rods 2, a connecting rope between the two foot pedals, an internal cable routing mechanism between the connecting rope and the two support rods 2, an assist rope fixed between the two foot pedals, an assist adjustment mechanism on the assist rope, and a handrail fixed to the support rod 1.

[0008] By adopting the above technical solution, the connecting rope for connecting the two foot pedals is built into the space between the two support rods and the connecting rod using an internal wiring mechanism. When the connecting rope moves back and forth, it stays inside the support rods and the connecting rod, thereby reducing the risk of fingers getting caught in the gap between the connecting rope and the support rods and the connecting rod when the connecting rope is placed externally, and improving the safety of using the stair climber.

[0009] Furthermore, the internal wiring mechanism includes a sliding seat fixed on the foot pedal, the sliding seat being slidably connected to the second support rod, a sliding block being fixed on the sliding seat, a sliding groove corresponding to the sliding block being opened on the second support rod, and wire-passing grooves being opened in both second support rods and the connecting rod, and interconnected with each other, and a connecting component being provided between the connecting rope and the sliding block.

[0010] By adopting the above technical solution, the two ends of the connecting rope are connected to the corresponding sliding blocks using connecting components, and then the connecting rope passes through the wire groove in the second support rod and the connecting rod. This reduces the risk of fingers getting caught in the gap between the connecting rope and the second support rod and the connecting rod when the connecting rope is placed externally, thus improving the safety of using the stair climber.

[0011] Furthermore, the connecting assembly includes a connecting block fixed on the sliding block, a threaded tube rotatably connected to the connecting block, and a threaded rod fixed to the end of the connecting rope, the threaded rod being threadedly connected to the threaded tube.

[0012] By adopting the above technical solution, the threaded tube on the connecting block is threadedly connected to the threaded rod on the connecting rope, thereby facilitating the connection and disassembly of the connecting rope and the sliding block.

[0013] Furthermore, each of the two support rods 2 is rotatably connected to a support wheel 1 at one end near the connecting rod, and the connecting rod is rotatably connected to a support wheel 2.

[0014] By adopting the above technical solution, when the connecting rope turns from the second support rod into the connecting rod, it is supported by the first support wheel, and when the connecting rope passes through the connecting rod, it is supported by the second support wheel. This reduces the possibility of friction when the connecting rope moves between the second support rod and the connecting rod.

[0015] Furthermore, the assist adjustment mechanism includes an adjustment box disposed on the assist rope, the assist rope passing through the adjustment box, an adjustment roller rotatably connected inside the adjustment box, the assist rope passing through the adjustment roller and fixedly connected to the adjustment roller, a rotating disk rotatably connected to the adjustment disk, the rotating disk passing through the adjustment box and fixedly connected to the adjustment roller, and a limit component provided between the rotating disk and the adjustment box.

[0016] By adopting the above technical solution, the adjusting roller rotates in the adjusting box, and the adjusting roller winds up the assist rope, thereby making it easy to adjust the length of the assist rope and the degree of assistance of the assist rope.

[0017] Furthermore, the limiting component includes a support block fixed on the adjustment box, a limiting rod slidably connected to the support block, and a plurality of circumferentially distributed limiting grooves on the rotating disk, the limiting grooves corresponding to the limiting rods.

[0018] By adopting the above technical solution, the limiting rod on the support block is inserted into the limiting groove on the rotating disk, thereby reducing the possibility that the assist rope will loosen on the adjusting roller after the adjusting roller winds up the assist rope.

[0019] Furthermore, a limit spring is provided between the end of the limiting rod away from the rotating disk and the support block, and both ends of the limit spring are fixedly connected to the support block and the limiting rod.

[0020] By adopting the above technical solution, the limiting spring is used to limit the limiting rod, thereby reducing the possibility that the limiting rod will disengage from the limiting groove during use.

[0021] Furthermore, wear-resistant rings are fixed at both ends of the adjustment box, and the assist rope passes through the wear-resistant rings.

[0022] By adopting the above technical solution, the assist rope moves into the adjustment box, and the wear-resistant ring on the adjustment box supports the assist rope, thereby reducing the friction between the assist rope and the adjustment box.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, during the installation of the connecting rope, the threaded rod at one end of the connecting rope is aligned with one of the sliding blocks. The threaded tube connected to the connecting block on the sliding block is aligned with the threaded rod of the connecting rope. Rotating the threaded tube allows the threaded rod to move within it, connecting the threaded rod to the threaded tube, thus completing the connection between the connecting rope and one of the sliding blocks. Then, the other end of the connecting rope passes through the wire groove of the second support rod, passes through the first support wheel on the second support rod, passes through the wire groove in the connecting rod, passes through the second support wheel, and then enters the wire groove of another second support rod, passing through the corresponding first support wheel. Finally, using the same connection method, the other sliding block is connected to the connecting rope, completing the internal wiring of the connecting rope. When the foot pedal is used, the foot pedal drives the sliding seat, which in turn drives the sliding block, causing the sliding block to move within the sliding groove, and the connecting rope to move back and forth. This reduces the risk of fingers being pinched in the gaps between the connecting rope and the second support rod or the connecting rod when the connecting rope is externally mounted, improving the safety of the stair climber. It also facilitates the disassembly and replacement of the connecting rope.

[0025] 2. In this application, when the assist strength of the assist rope needs to be adjusted, the limiting rod is pulled, allowing it to slide on the support block and disengage from the limiting groove. The rotating disk is then turned, causing the adjusting roller to rotate within the adjusting box. The adjusting roller then drives the assist rope, causing it to wind up onto the adjusting roller and move into the adjusting box. The wear-resistant ring on the adjusting box supports the assist rope. After the assist rope has been wound to the appropriate length, the limiting rod is released, allowing it to re-insert into the limiting groove on the rotating disk under the pull of the limiting spring. This fixes the rotating disk and the adjusting roller within the adjusting box, thus completing the adjustment of the assist rope length and achieving the purpose of changing the length and rebound force of the assist rope.

[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0034] This application discloses a stair-climbing machine with internal wiring.

[0035] Reference Figure 1 , Figure 2 and Figure 3 An internally wired stair climber includes a support rod 1, two symmetrical support rods 2 on one side of the support rod 1, a connecting rod 3 fixed between the two support rods 2, the connecting rod 3 being fixedly connected to the support rod 1, foot pedals 4 on each of the two support rods 2, a connecting rope 5 between the two foot pedals 4, an internal wiring mechanism 6 between the connecting rope 5 and the two support rods 2, an assist rope 8 fixed between the two foot pedals 4, an assist adjustment mechanism 7 on the assist rope 8, and a handrail 9 fixed on the support rod 1.

[0036] When using this stair climber, first, fix the connecting rod 3 between the support rod 1 and the two support rods 2 together. Then, install the handrail frame 9 on the support rod 1. Support rods are fixed between the support rod 1 and the two support rods 2 for ground support. Install the two pedals on the support rods 2 and connect them to the support rods 2 using the internal cable routing mechanism 6. The connecting rope 5 is placed inside the connecting rod 3 and the two support rods 2 using the internal cable routing mechanism 6 and connects the two pedals. After the pedals are installed, connect the two pedals using the assist rope 8. When the user uses it, the user steps on one of the pedals 4, and the pedal 4 slides down on the support rod 2. The pedal 4 drives the connecting rope 5, and the connecting rope 5 drives the other pedal 4, causing the other pedal 4 to slide up on the support rod 2. The user's other foot is on the rising pedal 4, and the user holds onto the handrail frame 9. The two foot pedals 4 move back and forth using the connecting rope 5. As the connecting rope 5 moves back and forth, it moves within the two support rods 2 and the connecting rod 3. When the two foot pedals 4 move up and down, they pull on the assist rope 8. The assist rope 8 becomes taut as the foot pedals 4 move up and down. The assist rope 8 is an elastic rope, and its elastic tension allows the foot pedals 4 to return to their original position. When the strength of the assist rope 8 needs to be adjusted, its length can be changed directly using the assist adjustment mechanism 7. The connecting rope 5, used to connect the two foot pedals 4, is internally housed between the two support rods 2 and the connecting rod 3 using the internal wiring mechanism 6. The connecting rope 5 remains inside the support rods 2 and the connecting rod 3 during its back and forth movement, thus reducing the risk of fingers being pinched in the gaps between the connecting rope 5 and the support rods 2 and the connecting rod 3 when the connecting rope 5 is externally placed, improving the safety of the stair climber.

[0037] Reference Figure 2 , Figure 3 and Figure 4The internal wiring mechanism 6 includes a sliding seat 61 fixed on the foot pedal 4. The sliding seat 61 is slidably connected to the second support rod 2. A sliding block 62 is fixed on the sliding seat 61. A sliding groove 63 corresponding to the sliding block 62 is opened on the second support rod 2. A wire-passing groove 64 is opened in both second support rods 2 and the connecting rod 3, and they are interconnected. A connecting component 65 is provided between the connecting rope 5 and the sliding block 62.

[0038] In addition, the connecting assembly 65 includes a connecting block 651 fixed on the sliding block 62, a threaded tube 652 rotatably connected to the connecting block 651, and a threaded rod 653 fixed to the end of the connecting rope 5, the threaded rod 653 being threadedly connected to the threaded tube 652.

[0039] Furthermore, each of the two support rods 2 has a support wheel 66 rotatably connected to one end near the connecting rod 3, and a support wheel 67 rotatably connected inside the connecting rod 3.

[0040] When installing the connecting rope 5, first align the threaded rod 653 at one end of the connecting rope 5 with one of the sliding blocks 62. Align the threaded tube 652, connected to the connecting block 651 on the sliding block 62, with the threaded rod 653 of the connecting rope 5. Rotate the threaded tube 652 to move the threaded rod 653 within it, connecting the threaded rod 653 to the threaded tube 652, thus completing the connection between the connecting rope 5 and one of the sliding blocks 62. Then, pass the other end of the connecting rope 5 through the threading groove 64 of the second support rod 2, pass through the first support wheel 66 on the second support rod 2, pass through the threading groove 64 in the connecting rod 3, pass through the second support wheel 67, and then enter the threading groove 64 of another second support rod 2, passing through the corresponding first support wheel 66. Finally, use the same connecting... Following this method, another sliding block 62 is connected to the connecting rope 5 to complete the internal wiring of the connecting rope 5. When the foot pedal 4 moves, the foot pedal 4 drives the sliding seat 61, and the sliding seat 61 drives the sliding block 62, allowing the sliding block 62 to move in the sliding groove 63, causing the connecting rope 5 to move back and forth. By passing the connecting rope 5 through the wire groove 64 in the two support rods 2 and the connecting rod 3, the connecting rope 5 can move back and forth in the two support rods 2 and the connecting rod 3. At the same time, the connecting rope 5 and the sliding block 62 can be connected by the threaded tube 652 and the threaded rod 653, thereby reducing the risk of hand pinching when the connecting rope 5 is placed externally, improving the safety of the stair climber, and making it easy to disassemble and replace the connecting rope 5.

[0041] Reference Figure 1 , Figure 2 and Figure 5The power assist adjustment mechanism 7 includes an adjustment box 71 mounted on a power assist rope 8, through which the power assist rope 8 passes. An adjustment roller 72 is rotatably connected inside the adjustment box 71. The power assist rope 8 passes through the adjustment roller 72 and is fixedly connected to the adjustment roller 72. A rotating disk 73 is rotatably connected to the adjustment disk, through which the rotating disk 73 passes through the adjustment box 71 and is fixedly connected to the adjustment roller 72. A limit component 74 is provided between the rotating disk 73 and the adjustment box 71.

[0042] In addition, the limiting component 74 includes a support block 742 fixed on the adjusting box 71, a limiting rod 741 slidably connected on the support block 742, and a plurality of circumferentially distributed limiting grooves 743 on the rotating disk 73, the limiting grooves 743 corresponding to the limiting rods 741.

[0043] Furthermore, a limit spring 744 is provided between the end of the limit rod 741 away from the rotating disk 73 and the support block 742, and both ends of the limit spring 744 are fixedly connected to the support block 742 and the limit rod 741.

[0044] Furthermore, wear-resistant rings 75 are fixed at both ends of the adjustment box 71, and the assist rope 8 passes through the wear-resistant rings 75.

[0045] When the assist strength of the assist rope 8 needs to be adjusted, pull the limit rod 741 to slide it on the support block 742, disengaging the limit rod 741 from the limit groove 743. Then, rotate the rotating disk 73 to drive the adjusting roller 72. The adjusting roller 72 rotates within the adjusting box 71, causing the assist rope 8 to wind up onto the adjusting roller 72 and move into the adjusting box 71. The wear-resistant ring 75 on the adjusting box 71 supports the assist rope 8. After the assist rope 8 is wound to the appropriate length, the limiting rod 741 is released, allowing the limiting rod 741 to be re-inserted into the limiting groove 743 on the rotating disk 73 under the pull of the limiting spring 744, thus fixing the rotating disk 73 and fixing the adjusting roller 72 in the adjusting box 71. This completes the adjustment of the length of the assist rope 8. By rotating the adjusting roller 72 in the adjusting box 71, the adjusting roller 72 winds up the assist rope 8, thereby changing the length of the assist rope 8 and changing the rebound force of the assist rope 8.

[0046] Working principle: When using this stair climber, first fix the connecting rod 3 between support rod 1 and the two support rods 2 together. Then, install the handrail 9 on support rod 1. Support rods are fixed between support rod 1 and the two support rods 2 for ground support. Install the two pedals on support rods 2. Align the threaded rod 653 at one end of the connecting rope 5 with one of the sliding blocks 62. Rotate the threaded tube 652 connected to the connecting block 651 on the sliding block 62 so that it aligns with the threaded rod 653 of the connecting rope 5. Rotate the threaded tube 652 so that the threaded rod 653 is aligned with the threaded tube 652. Move the threaded rod 653 to connect with the threaded tube 652, completing the connection between the connecting rope 5 and one of the sliding blocks 62. Then, pass the other end of the connecting rope 5 through the wire groove 64 of the second support rod 2, pass through the first support wheel 66 on the second support rod 2, pass through the wire groove 64 in the connecting rod 3, pass through the second support wheel 67, and then enter the wire groove 64 of the other second support rod 2, passing through the corresponding first support wheel 66. Finally, using the same connection method, connect the other sliding block 62 to the connecting rope 5, completing the internal wiring of the connecting rope 5. Then, according to actual needs... To adjust the assist rope 8, pull the limit rod 741, allowing it to slide on the support block 742 and disengage from the limit groove 743. Then, rotate the rotating disk 73, causing it to drive the adjusting roller 72. The adjusting roller 72 rotates within the adjusting box 71, driving the assist rope 8 to wind up onto the adjusting roller 72 and move into the adjusting box 71. The wear-resistant ring 75 on the adjusting box 71 supports the assist rope 8. After the assist rope 8 has been wound to the appropriate length, release the limit rod 741, allowing it to retract under the pull of the limit spring 744. Insert into the limiting groove 743 on the rotating disk 73 to fix the rotating disk 73, complete the adjustment of the assist rope 8, and finally the user steps on one of the foot pedals 4. The foot pedal 4 slides down on the support rod 2. The foot pedal 4 drives the connecting rope 5, and the connecting rope 5 drives the other foot pedal 4, so that the other foot pedal 4 slides up on the support rod 2. The user's other foot pedal 4 is on the rising foot pedal 4. The two foot pedals 4 are misaligned, so that the assist rope 8 is pulled, so that the assist rope 8 drives the foot pedal 4. The user holds the handrail frame 9 and steps down and down with both feet, so that the two foot pedals 4 move back and forth using the connecting rope 5.
