Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to an adjustable stair climber. Background Technology

[0002] Currently, there are various types of fitness equipment. A stair climber is a fitness machine that simulates climbing stairs. It includes a base frame and an inclined frame mounted on the base. Two pedals are mounted on the inclined frame and slidably connected to it. A rope connects the two pedals, and pulleys guide the rope on the inclined frame. Users step on the pedals to simulate climbing stairs.

[0003] However, the angle of the existing stair climber's inclined frame cannot be adjusted, making it impossible for the stair climber to meet the different needs of different users. Utility Model Content

[0004] This invention provides an adjustable-angle stair climber, aiming to solve the problem that the angle of the tilt frame of existing stair climbers cannot be adjusted, resulting in the stair climber not being able to meet the different needs of different users.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An adjustable stair climber includes a base frame and an inclined frame mounted on the base frame. The inclined frame is equipped with a pedal assembly and is rotatably connected to the base frame. A slide rail is provided on the inclined frame, and the pedal assembly is slidably connected to the slide rail.

[0007] An angle adjustment assembly is provided between the tilting frame and the base frame to adjust the angle of the tilting frame relative to the base frame. The angle adjustment assembly includes a positioning hole on the base frame and an angle adjustment hole on the tilting frame. There are several angle adjustment holes. The tilting frame is rotatably connected to the base frame via a rotating shaft. The several angle adjustment holes are arranged around the circumference of the rotating shaft. The angle adjustment assembly also includes a positioning pin that passes through the positioning hole and the angle adjustment hole. By operating the positioning pin, the positioning pin can be engaged with different angle adjustment holes to adjust the angle of the tilting frame relative to the base frame.

[0008] A further improvement: the slide rail is a metal slide rail.

[0009] Based on the above technical solution, metal slide rails possess advantages such as high strength, good wear resistance, and long service life, effectively improving the overall performance and user experience of the stair climber. The use of metal slide rails significantly enhances the overall performance and service life of the stair climber. The wear resistance and strength of the metal slide rails ensure that the pedal assembly maintains smooth sliding and good condition even after long-term use.

[0010] A further improvement: the base frame is a wooden base frame.

[0011] Based on the above technical solutions: Wood, as a natural resource, is relatively easy to obtain and widely distributed globally. Therefore, compared to some synthetic or metal materials, the raw material cost of wood is generally lower. In the processing, wood cutting and splicing are relatively simple, requiring less equipment and energy, which further reduces production costs. The production of wooden frames does not require complex manufacturing processes or high-precision processing equipment, reducing the technical difficulty and cost of manufacturing. Furthermore, due to the lightweight nature of wood, wooden frames are more convenient to transport and install, reducing related transportation and installation costs. Wood itself has good sound absorption and insulation properties. When sound waves encounter wood, some are absorbed by the wood, and some are reflected and dissipated within the wood, thus reducing noise propagation.

[0012] A further improvement: the tilting frame is a wooden tilting frame.

[0013] Based on the above technical solutions: Wood, as a widely available natural resource, has a relatively stable price and is generally lower than some synthetic or metal materials. Using a wooden inclined frame can effectively reduce the overall material cost of the stair climber, making the product more economical. Wood is relatively easy to process; it can be cut, spliced, and sanded into the required shape and size. Wood has a certain degree of elasticity and toughness, which can absorb and disperse vibration energy to some extent. This allows the wooden inclined frame to provide a certain degree of cushioning when subjected to external forces, reducing the transmission of vibration and noise.

[0014] A further improved solution: several angle adjustment holes are evenly arranged around the circumference of the rotating shaft.

[0015] Based on the above technical solution: Because the angle adjustment holes are evenly distributed, users can precisely adjust the angle of the tilting frame relative to the base frame by adjusting the positioning pins in conjunction with different angle adjustment holes, according to actual needs. This design allows the stair climber to adapt to stairs of varying slopes and meet the needs of users with different usage habits. The even distribution of the angle adjustment holes allows users to find the appropriate position more intuitively and quickly when adjusting the angle. This not only simplifies the operation process but also improves operational efficiency. At the same time, the evenly distributed design also helps reduce the problem of inaccurate angle adjustment due to misoperation.

[0016] A further improved solution: The slide rail includes a left slide rail and a right slide rail, the pedal includes a left pedal and a right pedal, the left pedal is slidably connected to the left slide rail, the right pedal is slidably connected to the right slide rail, the left pedal and the right pedal slide alternately, a pull rope is connected between the left pedal and the right pedal, and a pulley is provided on the tilting frame to guide the pull rope.

[0017] Based on the above technical solution: by dividing the pedals into left and right parts, each slidingly connected to a left and right rail, this design allows the pedals to maintain better stability and balance during movement. Especially during stair climbing, the alternating sliding of the left and right pedals effectively distributes the load, reducing the stress on a single pedal and thus extending the lifespan of the pedals and rails. The alternating sliding design of the left and right pedals allows users to adjust their pace and rhythm more flexibly when using the stair climber. This flexibility not only improves operational efficiency but also increases user comfort. Simultaneously, the configuration of the pull ropes and pulleys makes the connection between the pedals smoother, further enhancing the fluidity and comfort of operation. Dividing the pedals into left and right parts, each with its own rail, optimizes the space utilization of the stair climber. It allows the stair climber to accommodate a larger pedal area while maintaining a compact structure, thereby improving the user's standing stability and safety.

[0018] A further improved solution: The base frame is provided with a groove, a portion of the tilting frame extends into the groove, and the positioning hole communicates with the groove.

[0019] Based on the above technical solution: the portion of the tilting frame extending into the groove forms a tighter connection with the base frame. This physical contact increases the connection area between the two, thereby improving overall stability. During stair climbing, the tilting frame is subjected to vertical and horizontal forces from the stairs. The groove design allows these forces to be distributed more evenly onto the base frame, reducing the tilting frame's sway and improving the stability of the stair climber. Due to the presence of the groove, the positioning pin has a clear guide when passing through the positioning hole, ensuring it accurately mates with the required angle adjustment hole for precise positioning.

[0020] A further improved solution: There are two grooves arranged in parallel, and the positioning holes correspond one-to-one with the grooves. The tilting frame includes two plates extending into the grooves. The plates correspond one-to-one with the grooves, and each plate is provided with an angle adjustment hole. There are two positioning pins, and the positioning pins correspond one-to-one with the positioning holes.

[0021] Based on the above technical solution, two plates extend into two parallel grooves, providing double support for the tilting frame. This design significantly enhances the connection strength between the tilting frame and the base frame, making the stair climber more stable under load. Under stress, the two plates can more effectively distribute stress, avoiding structural damage caused by excessive stress at a single point. This improves the overall load-bearing capacity and durability of the stair climber. By adjusting the positioning pins and different angle adjustment holes, precise control of the tilting frame angle can be achieved. This helps ensure the stability and safety of the stair climber during the climbing process.

[0022] A further improved solution: A handrail is provided at the end of the tilting frame away from the base frame. The handrail includes a fixed rod mounted on the tilting frame and a sliding rod slidably connected to the fixed rod. The sliding rod is locked to the fixed rod by a locking assembly. The locking assembly includes a locking hole on the fixed rod, a slot on the sliding rod communicating with the locking hole, and a locking screw on the sliding rod that engages with the locking hole. The locking screw uses friction to lock the sliding rod to the fixed rod. The sliding rod is mounted on the fixed rod by at least two locking assemblies.

[0023] Based on the above technical solution: the handrail provides users with additional support points, especially during stair climbing, allowing them to hold the handrail more stably and reducing safety hazards caused by body swaying. The sliding bar can slide on the fixed bar and lock in place via a locking assembly, meaning users can adjust the handrail height according to their height and comfort level. This design makes the stair climber more user-friendly and improves user comfort.

[0024] A further improved solution: The fixed rod is rotatably connected to the tilting frame. Both the tilting frame and the fixed rod are provided with holes. A pin that mates with the hole is inserted into the hole. The angle of the fixed rod relative to the tilting frame is locked by the engagement of the pin with the hole.

[0025] Based on the above technical solution: Since the fixed rod and the tilting frame are connected by rotation, users can adjust the angle of the fixed rod to meet different usage scenarios according to actual needs. This design makes the stair climber more flexible and adaptable. The fixed rod angle can be stably locked through the cooperation of the pin and the hole. This locking method is simple and effective, ensuring that the fixed rod will not loosen or change angle due to force during use.

[0026] The beneficial effects of this utility model are as follows:

[0027] This invention, by incorporating an angle adjustment component, allows users to easily manipulate the positioning pin, passing it through positioning holes on the base frame and different angle adjustment holes on the tilt frame, thereby achieving precise adjustment of the tilt frame's angle relative to the base frame. This design breaks the limitation of the fixed tilt frame angle in traditional stair climbers, enabling the stair climber to flexibly adapt to the needs of different users and various usage scenarios. The adjustability of the tilt frame angle not only enhances the applicability of the stair climber but also greatly optimizes the user experience. Users can adjust the tilt frame to the most comfortable angle according to their actual situation, reducing physical exertion and discomfort during stair climbing. Simultaneously, the sliding design of the pedal assembly on the slide rail allows users to move more smoothly and steadily when going up and down stairs, further improving the convenience and comfort of use.

[0028] The locating pins and angle adjustment holes in the angle adjustment assembly are rationally designed, easy to clean, and can extend service life and reduce failure rate. Meanwhile, the connection between the pedal assembly and the slide rail is designed for easy disassembly and replacement, allowing users to easily perform maintenance and upkeep when needed.
