Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and more specifically it relates to a stair climber. Background Technology

[0002] A stair climber is a multi-functional aerobic training fitness machine that simulates mountain climbing. It is named for its resemblance to mountain climbing and is a fitness product that emerged after the treadmill. Its main principle is that the exerciser uses the continuous back-and-forth movement of both feet on a machine with a large incline to imitate outdoor mountain climbing and thus achieve fitness goals.

[0003] Currently, the handrail adjustment mechanisms of traditional mountaineering machines are usually of two types: pin-type angle adjustment structure and bolt-locking connection structure. Among them, the pin-type angle adjustment structure achieves multi-level adjustment by inserting a spring pin into different positioning holes. During use, there is a gap between the pin and the hole, which causes the handrail to wobble easily during high-intensity exercise. Frequent adjustment can cause wear on the hole, resulting in a short lifespan. Moreover, it cannot be infinitely adjusted. Bolted locking connections require complete removal of the bolts to fold the handrail, which is time-consuming and prone to parts loss. While some quick-release structures simplify the operation, they rely on single-point locking, which can lead to insufficient locking force, causing the handrail to loosen easily and posing a safety hazard. Furthermore, the handrail cannot rotate freely when folded, requiring manual support and affecting storage efficiency.

[0004] Therefore, there is an urgent need for a climbing machine to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a climbing machine with the advantage of convenient and quick adjustment of the handrail angle.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A climbing machine includes a climbing machine body, a handrail assembly, and a pedal movement system. The climbing machine body has a fixed seat on each of its left and right sides. The handrail assembly includes a handrail tube and two connecting arms, which are symmetrically arranged at the left and right ends of the handrail tube and extend downward. The lower end of each connecting arm is connected to the corresponding fixed seat through an angle adjustment component. The angle adjustment assembly includes: a fixed disk, fixedly mounted on the fixed base, the fixed disk having a first end face tooth on its end face facing the connecting arm; a rotating disk, fixedly mounted on the connecting arm, the rotating disk having a second end face tooth on its end face facing the fixed disk; an adjustment shaft assembly, connecting the fixed base and the connecting arm, and passing through the center hole of the fixed disk and the rotating disk; and an operating member, acting on the adjustment shaft assembly, for driving the rotating disk to press against or move away from the fixed disk axially, so that the second end face tooth engages and locks or disengages from the first end face tooth, thereby realizing the angle adjustment or folding and storage of the armrest assembly.

[0007] The advantages of this scheme are at least as follows: by setting fixed seats on both sides of the main body of the mountaineering machine and introducing an angle adjustment component consisting of a fixed plate, a rotating plate, an end face tooth, an adjustment shaft assembly and an operating component at the lower end of the connecting arm of the handrail assembly, an adjustable connection between the handrail assembly and the machine body is realized. In use, by rotating the operating component, the operating component drives the adjusting axial component to rotate forward or backward, thereby causing the first end face tooth to move closer to or further away from the second end face tooth. When the first and second end face teeth are axially pressed together by the adjusting axial component, the end face teeth are fully engaged, forming a rigid connection and achieving angle locking. When the axial pressure is released, the tooth surfaces separate, and the connecting arm can rotate freely around the central axis to achieve angle adjustment or folding for storage. Compared to traditional bolt locking or pin positioning methods, this angle-adjustable positioning method has advantages such as stepless adjustment, precise positioning, quick operation, and compact structure. It greatly improves the adaptability and comfort for users of different heights and exercise postures, while ensuring structural stability and safety under high-intensity use.

[0008] The present invention is further configured such that the adjusting shaft assembly includes: A rotating shaft is fixedly mounted at the end of the connecting arm, passes through the central hole of the fixed disk and the rotating disk, and extends into the interior of the fixed base; An adjusting screw passes through the center hole of the rotating shaft and is threadedly connected to the fixed seat. The operating component is a knob connected to the end of the adjusting screw. Rotating the knob can drive the adjusting screw to move axially, thereby causing the rotating shaft and rotating disk to press towards or away from the fixed disk.

[0009] The advantages of this scheme are at least as follows: by setting the adjusting shaft assembly into a structure of a rotating shaft, an adjusting screw, and a knob, since the rotating shaft passes through the center holes of the fixed disk and the rotating disk respectively, when the user rotates the knob, the adjusting screw generates axial displacement under the action of the thread, thereby pushing or pulling the rotating shaft to move axially, thus causing the rotating disk to press against or disengage from the fixed disk. This cleverly transforms the rotational action into axial locking force, and utilizes the self-locking characteristic of the thread to achieve long-term stable locking. This makes operation labor-saving, locking reliable, structurally simple, easy to manufacture and maintain, and the adjustment accuracy can be controlled by adjusting the pitch of the adjusting screw to achieve fine-tuning function.

[0010] The present invention is further configured such that: the angle adjustment assembly further includes: an elastic reset member, the elastic reset member being sleeved on the adjustment screw and located inside the fixed base; One end of the elastic reset member acts on the fixed base, and the other end acts on the rotating shaft; When the knob is released to release the rotating disk, the elastic reset member pushes the rotating shaft and the rotating disk axially away from the fixed disk, causing the first end face teeth to separate from the second end face teeth.

[0011] The advantages of this design are at least as follows: An elastic reset component (such as a compression spring) is added to the adjustment shaft assembly, fitted onto the adjustment screw, with one end abutting against the fixed seat and the other end abutting against the end face of the rotating shaft. When the user rotates the knob counterclockwise (in the loosened state), the adjustment screw retracts, releasing the elastic potential energy stored in the compression spring, pushing the rotating shaft and disc to quickly move axially backward, causing the second end face teeth to rapidly separate from the first end face teeth, achieving automatic unlocking. Compared to the cumbersome operation of traditional structures that require manual manipulation or tapping to unlock, this design significantly improves adjustment efficiency and user experience, making it particularly suitable for frequent adjustments or storage scenarios.

[0012] The present invention is further configured such that the elastic reset element is a compression spring.

[0013] The advantages of this scheme are at least as follows: using a compression spring as an elastic reset component has the advantages of simple structure, low cost, rapid response, long service life and convenient installation. At the same time, the compression spring can also effectively absorb the small vibrations and impacts during the adjustment process, improving the quietness and stability of the overall structure.

[0014] The present invention is further configured such that the angle adjustment component also includes a limiting component for limiting the rotation angle range of the rotating disk relative to the fixed disk.

[0015] The advantages of this solution are at least as follows: by setting a limiting component to limit the rotation angle range of the rotating disk relative to the fixed disk, it prevents structural interference, damage to the end face teeth, or safety hazards caused by excessive rotation when the user adjusts the handrail angle.

[0016] The present invention is further configured such that the limiting component includes: The limiting component is fixedly installed on the main body of the mountaineering machine; Limiting holes are provided on the rotating disk, and several of them are provided; The limiting member cooperates with the limiting hole, and slides within the limiting hole when the rotating disk rotates.

[0017] The advantages of this scheme are at least as follows: during use, the rotating disk of the limiting component rotates with the connecting arm, causing the limiting component to slide in the arc-shaped hole. When its two ends contact the hole wall, it reaches the rotation limit position, thereby achieving a small-amplitude angle adjustment. When a large angle adjustment is required, the adjusting screw and the fixing seat need to be loosened so that the limiting part is disengaged from the limiting hole before making a large angle adjustment. After the user feels that the adjustment is in a suitable position, the limiting part can be inserted into other limiting holes for detailed angle adjustment.

[0018] The present invention is further configured such that the limiting hole is an arc-shaped hole.

[0019] The advantages of this scheme are at least as follows: the limiting hole is designed as an arc-shaped hole, with its center coinciding with the rotation center of the rotating disk. During use, when the limiting component slides to either end of the arc-shaped hole, it is blocked by the hole wall, thereby rigidly limiting the maximum rotation angle of the rotating disk (i.e., the handrail) and effectively preventing structural damage caused by excessive rotation by the user.

[0020] The present invention is further configured such that buffer pads are provided at both ends of the arc-shaped hole to absorb the impact force of the limiting member and reduce noise.

[0021] The advantages of this solution are at least as follows: when the limiting component slides to either end of the arc-shaped hole, the buffer pad immediately disengages from the limiting component, effectively absorbing impact energy and reducing rigid collisions between metal parts, thereby improving the product's quietness and premium feel during use. Simultaneously, the buffer pad also reduces wear on the edge of the limiting hole from long-term impacts, preventing burrs or deformation, thus extending the service life of the limiting component.

[0022] The present invention is further configured such that: the fixed base is provided with a receiving cavity; the end of the rotating shaft, the elastic reset member and part of the adjusting screw are received in the receiving cavity; one end of the elastic reset member abuts against the bottom wall of the receiving cavity and the other end abuts against the end face of the rotating shaft.

[0023] The advantages of this solution are at least as follows: by accommodating the end of the rotating shaft, the elastic reset component (compression spring), and part of the adjusting screw within the cavity of the fixed base, the key adjusting mechanism is embedded in the design. This design not only makes the external appearance neat and beautiful, but also avoids exposed parts from affecting the overall shape and reduces the risk of being snagged or damaged by external objects (clothing).

[0024] The present invention is further provided that: the outer surface of the operating component is provided with anti-slip texture.

[0025] The advantages of this design are at least as follows: the anti-slip texture increases the friction between the fingers and the knob, allowing users to easily apply force to rotate the knob even when their hands are wet, sweaty, or wearing gloves, without slipping.

[0026] In summary, this utility model has at least the following advantages: 1. By setting the angle adjustment component, the handrail component can achieve stepless, precise, and fast angle adjustment and high-strength locking, which gets rid of the limitations of traditional hole positioning and significantly improves human-machine adaptability and usage flexibility. 2. By setting an integrated adjusting shaft assembly (including adjusting screw, rotating shaft, compression spring and knob), the efficient conversion from rotation operation to axial locking / releasing is realized, and automatic unlocking is achieved with the help of elastic reset component. The operation is labor-saving and convenient, and the locking is reliable. 3. By setting a limiting component (arc-shaped hole + limiting piece + buffer pad) and an embedded receiving cavity structure, the safety, quietness and structural durability of the adjustment process are effectively guaranteed, while improving the overall appearance and protective performance.

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1:

[0030] like Figure 1 , Figure 2 As shown, a climbing machine includes a climbing machine body 1, a handrail assembly 2, and a pedal movement system 3, and also includes support feet for supporting the pedal movement system 3. A fixed seat 4 is provided on the left and right sides of the climbing machine body 1 respectively. The handrail assembly 2 includes a handrail tube 201 and two connecting arms 202, which are symmetrically arranged at the left and right ends of the handrail tube 201 and extend downward. The lower end of each connecting arm 202 is connected to the corresponding fixed seat 4 through an angle adjustment component 5.

[0031] like Figure 3 As shown, the angle adjustment assembly 5 includes: a fixed disk 501, fixedly mounted on the fixed base 4, with a first end face tooth 6 on the end face of the fixed disk 501 facing the connecting arm 202; a rotating disk 502, fixedly mounted on the connecting arm 202, with a second end face tooth 7 on the end face of the rotating disk 502 facing the fixed disk 501; an adjustment shaft assembly 503, connecting the fixed base 4 and the connecting arm 202, and passing through the center hole of the fixed disk 501 and the rotating disk 502; and an operating member 504, acting on the adjustment shaft assembly 503, for driving the rotating disk 502 to press axially or move away from the fixed disk 501, so that the second end face tooth 7 engages and locks or separates and releases from the first end face tooth 6, thereby realizing the angle adjustment or folding and storage of the armrest assembly 2.

[0032] like Figure 4 As shown, the adjusting shaft assembly 503 includes: a rotating shaft 5031, fixedly mounted on the end of the connecting arm 202, passing through the central holes of the fixed disk 501 and the rotating disk 502, and extending into the interior of the fixed seat 4; an adjusting screw 5032, passing through the central hole of the rotating shaft 5031 and threadedly connected to the fixed seat 4; and an operating member 504, which is a knob connected to the end of the adjusting screw 5032. Rotating the knob can drive the adjusting screw 5032 to move axially, thereby causing the rotating shaft 5031 and the rotating disk 502 to press towards or away from the fixed disk 501. The outer surface of the operating member 504 is provided with anti-slip texture.

[0033] In use, by rotating the operating component 504, the operating component 504 drives the adjusting axial component to rotate forward or backward, thereby causing the first end face tooth 6 to move closer to or further away from the second end face tooth 7. When the first end face tooth 6 and the second end face tooth 7 are axially pressed together by the adjusting axial component, the end face teeth are fully engaged, forming a rigid connection and achieving angle locking. When the axial pressure is released, the tooth surfaces separate, and the connecting arm 202 can rotate freely around the central axis to achieve angle adjustment or folding for storage.

[0034] In some other embodiments, the first end face tooth 6 and the second end face tooth 7 can be two first half end face teeth and two second half end face teeth, wherein the two first half end face teeth and the two second half end face teeth are radially opposite each other, and the second half end face teeth have one more tooth than the first half end face teeth. Example 2:

[0035] like Figure 4 , Figure 5 As shown, in some preferred embodiments, to facilitate the better ejection of the rotating disk 502 from the fixed disk 501, the angle adjustment assembly 5 further includes: an elastic reset member 505, which is sleeved on the adjusting screw 5032 and located inside the fixed seat 4, wherein the elastic reset member 505 is a compression spring; the fixed seat 4 is provided with a receiving cavity 9; the end of the rotating shaft 5031, the elastic reset member 505, and part of the adjusting screw 5032 are received in the receiving cavity 9; one end of the elastic reset member 505 abuts against the bottom wall of the receiving cavity 9, and the other end abuts against the end face of the rotating shaft 5031. One end of the elastic reset member 505 acts on the fixed seat 4, and the other end acts on the rotating shaft 5031; when the knob is released to release the rotating disk 502, the elastic reset member 505 pushes the rotating shaft 5031 and the rotating disk 502 axially away from the fixed disk 501, causing the first end face tooth 6 to separate from the second end face tooth 7.

[0036] More specific operation is as follows: When the user rotates the knob counterclockwise (in the loose state), the adjusting screw 5032 retracts, the elastic potential energy stored in the compressed spring is released, and the rotating shaft 5031 and the rotating disk 502 are pushed to quickly move axially backward, so that the second end face tooth 7 and the first end face tooth 6 are quickly separated, thus achieving automatic unlocking. Example 3:

[0037] like Figures 3-5As shown, to prevent excessive rotation when adjusting the armrest angle, in some preferred embodiments, the adjustment assembly further includes a limiting component 506 for limiting the rotation angle range of the rotating disk 502 relative to the fixed disk 501. The limiting component 506 includes: a limiting member 5061, fixedly mounted on the main body 1 of the climbing machine; and several limiting holes 5062 located on the rotating disk 502, wherein the limiting holes 5062 are arc-shaped. The limiting member 5061 cooperates with the limiting holes 5062, and when the rotating disk 502 rotates, the limiting member 5061 slides within the limiting holes 5062, and its contact with both ends of the hole limits the rotation angle range.

[0038] During use, the rotating disk 502 rotates with the connecting arm 202, causing the limiting member 5061 to slide in the arc-shaped hole. When its two ends contact the hole wall, it reaches the rotation limit position, thereby realizing a small-amplitude angle adjustment. When a large angle adjustment is required, the adjusting screw 5032 and the fixed seat 4 need to be loosened so that the limiting member 5061 can be disengaged from the limiting hole 5062 before making a large angle adjustment. After the user feels that the adjustment is in a suitable position, the limiting member 5061 can be inserted into other limiting holes 5062 for detailed angle adjustment. In some preferred embodiments, to reduce noise when the limiting member 5061 slides to either end of the arc-shaped hole, buffer pads 8 are provided at both ends of the arc-shaped hole to absorb the impact force of the limiting member 5061 and reduce noise. In some other embodiments, an arc-shaped ring is provided within the entire arc surface of the arc-shaped hole. The arc-shaped ring can be made of plastic or other hard and wear-resistant materials. The arc-shaped ring is embedded in the entire arc-shaped hole, thereby separating the limiting member 5061 and the limiting hole 5062 and avoiding direct contact between the limiting member 5061 and the limiting hole 5062, thus preventing noise generation. Example 4:

[0039] Based on Embodiment 1, Embodiment 2, or Embodiment 3, this utility model also provides a method for adjusting the angle of the handrail on a stair climber, the steps of which are as follows: S1 (Unlocking process): The user holds and rotates the knob (operating part 504) at the end of the armrest counterclockwise. The knob drives the adjusting screw 5032 to rotate together. Since the adjusting screw 5032 is threadedly engaged with the threaded hole on the fixed base 4, rotating counterclockwise will cause the adjusting screw 5032 to move axially backward (away from the fixed plate 501). The movement of the adjusting screw 5032 relaxes the axial clamping force previously applied to the rotating disk 502 via the rotating shaft 5031. At this time, the elastic reset member 505 (compression spring) that has been compressed begins to release its elastic force. Under the action of the spring force, the rotating shaft 5031 (and the rotating disk 502 fixed on it) is pushed to move axially backward, away from the fixed disk 501. As the rotating disk 502 moves backward, the second end face tooth 7 on its end face completely disengages (separates) from the first end face tooth 6 on the fixed disk 501. At this time, the handrail assembly 2 (through the connecting arm 202 and the rotating shaft 5031) is in the "unlocked" state, the rotating disk 502 is no longer constrained by the fixed disk 501, and the handrail assembly 2 can rotate around the axis of the adjusting shaft assembly 503.

[0040] S2 (Angle Adjustment Process): In the unlocked state, the user holds the handrail tube 201 and pushes / pulls the handrail forward or backward as needed. The movement of the handrail is transmitted to the rotating shaft 5031 through the connecting arm 202, causing the rotating disk 502 to rotate together. During the rotation, the limiting piece 5061 fixed on the main body 1 of the climbing machine slides in the arc-shaped limiting hole 5062 of the rotating disk 502. When the handrail is rotated to the angle desired by the user, the pushing / pulling stops. When a large angle adjustment is required, the adjusting screw 5032 and the fixed seat 4 need to be loosened so that the limiting member 5061 disengages from the limiting hole 5062. Then, the user pushes / pulls the handrail forward or backward. The movement of the handrail is transmitted to the rotating shaft 5031 through the connecting arm 202, which drives the rotating disk 502 to rotate together. After the user feels that the adjustment is in a suitable position, the limiting member 5061 is inserted into other limiting holes 5062 for detailed angle adjustment.

[0041] S3 (Locking process): After adjusting the handrail, keep the handrail at the desired angle position, and rotate the knob to drive the adjusting screw 5032 to rotate clockwise. The adjusting screw 5032 is threaded with the fixed seat 4, so that it moves forward axially (towards the fixed plate 501). The forward movement of the adjusting screw 5032 pushes the rotating shaft 5031, which in turn drives the rotating disk 502 to move forward along the axial direction and press against the fixed disk 501. The second end face tooth 7 on the rotating disk 502 and the first end face tooth 6 on the fixed disk 501 gradually approach each other and finally mesh tightly. As the knob is tightened further, the axial tension provided by the adjusting screw 5032 forcefully presses the two end teeth together, forming a secure mechanical lock. During this process, the spring is recompressed. At this point, the handrail assembly 2 is "locked" again at the new angular position. The engagement of the end face teeth completely prevents the rotation of the rotating disk 502 (i.e., the handrail).

[0042] S4 (Folding and Storage Process): Execute the "Unlocking Process" (S1) to separate the end face teeth and cause the limiting member 5061 to disengage from the limiting hole 5062. Then, execute the large angle adjustment in the "Angle Adjustment Process" (S2) until the armrest is folded and stored. Then, execute the "Locking Process" (S3).

[0043] The beneficial effects of this utility model are as follows: The stair climber's handrail angle adjustment system employs an end-face tooth meshing structure for a stable lock, effectively resisting swaying during exercise and ensuring safety. Through the linkage between the screw and the knob, users can quickly lock or release the handle with one hand, offering convenience and efficiency. An internal compression spring automatically pushes the rotating disk 502 when the knob is released, causing the teeth to separate and enabling smooth unlocking. Limiting holes 5062 and limiting components 5061 work together to limit the rotation range, preventing over-adjustment. Buffer pads 8 are added to both ends to effectively reduce shock and noise, improving quietness and durability. The core components are integrated into the receiving cavity 9 of the fixed base 4, resulting in a compact structure, clean appearance, and dust protection. The knob surface has anti-slip textures, preventing slippage even when sweaty, making operation more comfortable.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
