Description

Technical Field

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

[0002] The glide step machine is a type of fitness machine that allows users to glide their feet back and forth along a track. Because it is easy to operate, can assist users in exerting force, does not cause leg and foot strain, and can still provide exercise benefits, it is very popular among users of all ages.

[0003] Existing steppers typically include a base with a guide rail on it, and pedals mounted on the guide rail, sliding along the rail. An elastic element is installed between the pedals and the base to generate resistance during pedal sliding, thus optimizing the stepper's performance. However, in existing steppers, the elastic element and pedals are connected using a connecting frame, which results in a complex structure and high manufacturing costs. Utility Model Content

[0004] This invention provides a stepper machine, which aims to solve the problems of complex structure and high manufacturing cost of existing stepper machines.

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

[0006] A stepper includes a base and a guide rail disposed on the base. A pedal assembly is disposed on the guide rail, the pedal assembly is slidably connected to the guide rail, and the pedal assembly slides along the guide rail.

[0007] An elastic component is provided between the pedal assembly and the base to provide damping force to the pedal assembly. The elastic component includes an elastic element, one end of which is disposed on the base. The elastic component also includes a connecting shaft, and the other end of which is disposed on the pedal assembly through the connecting shaft. The elastic element uses the friction between the connecting shaft and the pedal assembly to position the axial position of the connecting shaft by tightening the connecting shaft.

[0008] A further improved solution: The pedal assembly is provided with a mounting groove for mounting the connecting shaft, and the mounting groove is U-shaped.

[0009] Based on the above technical solution, the U-shaped mounting groove provides a stable supporting environment for the connecting shaft. This design ensures that the connecting shaft is not easily loosened or shifted after installation, thereby enhancing the overall structural stability of the stepper. During use, even under significant force or vibration, the connecting shaft will remain in its predetermined position, ensuring the normal operation of the stepper. The U-shaped mounting groove design makes the installation and removal of the connecting shaft relatively simple. Technicians or users can complete the installation or removal process through simple operations, such as sliding the connecting shaft into or out of the mounting groove. This not only saves time but also reduces operational difficulty and improves work efficiency.

[0010] A further improvement: A rib is provided on the lower side of the pedal assembly to improve the strength of the pedal assembly, and the mounting groove is provided on the rib.

[0011] Based on the above technical solution: Ribs, as reinforcing structures, can significantly improve the rigidity and load-bearing capacity of the pedal assembly. When the pedal assembly is subjected to external forces, the ribs can effectively disperse and resist these forces, preventing the pedal from deforming or being damaged. Placing the mounting slot on the ribs further enhances the stability of the mounting slot. The ribs provide a robust supporting foundation for the mounting slot, making the connecting shaft more stable after installation and less prone to loosening or detachment. This helps ensure the smoothness and safety of the stepper during operation. The design of the ribs can also optimize the stress distribution of the pedal assembly. By rationally arranging the position and number of ribs, the pedal assembly can be subjected to more even stress when subjected to external forces, thereby reducing the risk of localized stress concentration and fatigue damage.

[0012] A further improved solution: The elastic component further includes a shaft, and the elastic element is mounted on the base via the shaft.

[0013] Based on the above technical solution: the shaft, as a key component connecting the elastic element and the base, is designed to ensure the stable installation of the elastic element on the base. This stable connection effectively prevents the elastic element from loosening or shifting during movement, thereby enhancing the overall stability of the stepper. Fixing the elastic element to the base via the shaft allows for more precise control of its tension and position. This helps provide a uniform and stable damping force to the pedal assembly, optimizing the stepper's elastic support and making the movement smoother and more comfortable. The shaft design simplifies the installation process of the elastic element. Technicians can easily fix the elastic element to the base via the shaft without complex connecting brackets or other auxiliary parts. Furthermore, when maintenance or replacement of the elastic element is required, it can be quickly disassembled and reinstalled via the shaft, improving maintenance convenience.

[0014] A further improved solution: The elastic element is an elastic ring formed by an elastic rope, with one end of the elastic ring wrapped around the connecting shaft and the other end of the elastic ring wrapped around the shaft body.

[0015] Based on the above technical solutions, the elastic ring design provides continuous and stable elastic support, ensuring that the pedal assembly experiences uniform resistance during sliding. This stable elastic support helps improve the user's exercise experience, making the stepper smoother and more comfortable. The installation of the elastic ring is relatively simple; simply wrap both ends around the connecting shaft and the shaft body respectively. This design simplifies the installation process, reduces installation difficulty, and also facilitates subsequent maintenance and replacement. As an elastic component, the elastic ring has a relatively compact structure and does not occupy excessive space. This helps optimize the overall structure of the stepper, making it more compact, lightweight, and easy to carry and store. The elastic rope material typically has high wear resistance and anti-aging properties, ensuring that the elastic ring maintains stable elasticity during long-term use. This helps extend the lifespan of the stepper and reduce maintenance costs caused by damage to the elastic component.

[0016] A further improved solution: There are two elastic components, which are respectively disposed at both ends of the pedal assembly.

[0017] Based on the above technical solution, two elastic components are located at both ends of the pedal assembly, providing uniform support and damping force. This design helps ensure the stability of the pedal during gliding, reducing the risk of wobbling or tilting. Simultaneously, it enhances the overall stability of the stepper, allowing users to exercise with greater peace of mind. Through the synergistic effect of the two elastic components, the sliding resistance and rebound effect of the pedal assembly can be more precisely controlled. This design allows the stepper to adapt to the strength and exercise needs of different users, providing a more personalized exercise experience. Furthermore, it helps optimize energy transfer and consumption during exercise, improving training effectiveness. Placing the two elastic components at both ends of the pedal assembly also strengthens the pedal assembly structure. This layout disperses the pressure on the pedal when under stress, reducing the risk of localized stress concentration and thus extending the lifespan of the pedal assembly. The design of having two elastic components at each end of the pedal assembly makes it easier for technicians to access and operate during maintenance or adjustments. This reduces maintenance costs and time, improving the usability and reliability of the stepper.

[0018] A further improved solution: The two elastic components are respectively disposed at the left and right ends of the pedal assembly.

[0019] Based on the above technical solution, two elastic components are located at the left and right ends of the pedal assembly, ensuring that the pedal receives uniform support and damping force in the lateral direction. This design helps prevent the pedal from tilting or wobbling during gliding, thereby enhancing the balance and stability of the stepper. This is crucial for improving the user's exercise experience and safety. Placing the two elastic components at the left and right ends of the pedal assembly also strengthens the pedal assembly structure. This layout disperses the pressure on the pedal under stress, reducing the risk of localized stress concentration, thus extending the service life of both the pedal assembly and the elastic components.

[0020] A further improved solution: There are two guide rails, and the elastic component is located between the two guide rails.

[0021] Based on the above technical solution: the guide rail, as a key component of the stepper, provides precise guidance for the pedal assembly. Placing the elastic component between the two guide rails ensures that the elastic force always acts along the direction of the guide rail during pedal sliding, thereby enhancing the stability and accuracy of the stepper. Simultaneously, the guide rails also provide support for the elastic component, preventing it from shifting or deforming during movement. The location of the elastic component between the guide rails allows the elastic force to be transferred to the pedal assembly more directly and effectively. This design helps reduce energy loss during transmission, improving the stepper's exercise efficiency and training effect. The ingenious combination of the guide rails and the elastic component actually constitutes part of the stepper's structure. Placing the elastic component between the guide rails disperses the pressure on the pedals when under force, reducing the risk of localized stress concentration. This design not only enhances the overall structural strength of the stepper but also helps extend its service life. Placing the elastic component between the guide rails simplifies the installation process. Technicians can easily install the elastic component by positioning it using the guide rails, without the need for additional positioning devices or complex installation steps. When resilient components need repair or replacement, technicians can quickly disassemble and reinstall them, reducing maintenance costs and time.

[0022] A further improved solution: the two guide rails are located on the front and rear sides of the pedal assembly, respectively.

[0023] Based on the above technical solution: the guide rail, as a key component of the stepper, primarily functions to provide precise guidance and positioning for the pedal assembly. Placing two guide rails on the front and rear sides of the pedal assembly ensures that the pedals always move along the direction of the guide rails during gliding, thus maintaining a stable trajectory. This design helps reduce pedal wobbling or deflection during gliding, improving the stability and accuracy of the stepper. The front-rear layout of the guide rails allows the pedal assembly to receive more even and stable support during gliding. This design helps optimize exercise effects, making the user's movement smoother and more natural. Simultaneously, by adjusting the distance or angle between the guide rails, the resistance level and exercise mode of the stepper can be easily changed to adapt to the strength and exercise needs of different users. Placing the two guide rails on the front and rear sides of the pedal assembly also constitutes part of the stepper's structure. This design helps enhance the overall structural strength of the stepper, improving its load-bearing capacity and durability. The stable support of the guide rails also reduces the risk of pedal deformation or damage under stress, extending the lifespan of the stepper.

[0024] A further improved solution: the guide rail is welded to the base.

[0025] Based on the above technical solutions: Welding, as a robust connection method, tightly binds the guide rail and base together, forming a stable integrated structure. This design enhances the overall stability of the stepper, preventing wobbling or tilting during use. Welding makes the connection between the guide rail and base extremely strong, capable of withstanding greater weight and pressure. This is particularly important for steppers that need to withstand significant impact or heavy loads, ensuring the safety and reliability of the equipment during long-term use. Welded guide rails simplify the installation process, eliminating the need for additional connectors or fasteners. Simultaneously, the strong welded connection reduces maintenance issues caused by loose or damaged connectors. This lowers maintenance costs and time, improving the availability and reliability of the equipment. Welded guide rails ensure straightness and parallelism, providing precise guidance for the pedal assembly. This design helps optimize the stepper's movement, making the pedals smoother and more fluid during gliding. Welded connections offer high strength and durability, withstanding wear and fatigue during long-term use. This helps extend the stepper's lifespan and reduces replacement costs due to component damage.

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

[0027] This invention employs a unique connection method between the elastic component and the pedal assembly. One end of the elastic component is mounted on the base, while the other end is connected to the pedal assembly via a connecting shaft. The axial position of the connecting shaft is positioned using the friction between the connecting shaft and the pedal assembly. This design significantly simplifies the structure of the stepper. Compared to the complex connecting frame used in traditional steppers where the elastic component connects to the pedal, this design reduces the number and complexity of parts, thereby lowering manufacturing costs.

[0028] Thanks to its simplified structure and optimized performance, this stepper offers users a smoother and more stable gliding experience. Users can more easily glide back and forth along the guide rails, resulting in better fitness outcomes. Furthermore, the simplified structure makes the stepper easier to maintain and clean, extending its lifespan. Attached Figure Description

[0038] An elastic component is provided between the pedal assembly 3 and the base 1 to provide damping force to the pedal assembly 3. The elastic component includes an elastic element 4, one end of which is disposed on the base 1. The elastic component also includes a connecting shaft 5, and the other end of the elastic element 4 is disposed on the pedal assembly 3 through the connecting shaft 5. The elastic element 4 uses the friction between the connecting shaft 5 and the pedal assembly 3 to position the axial position of the connecting shaft 5 by tightening the connecting shaft 5.

[0039] The pedal assembly 3 has a U-shaped mounting groove 6 for mounting the connecting shaft 5. A rib 7, designed to enhance the strength of the pedal assembly 3, is located on the lower side of the pedal assembly 3, and the mounting groove 6 is disposed on the rib 7. The rib 7 and the pedal assembly 3 are integrally formed. Multiple ribs 7 are evenly distributed along the front-rear direction of the pedal assembly 3. Each of the multiple ribs 7 has a corresponding mounting groove 6, allowing the connecting shaft 5 to simultaneously engage with the mounting grooves 6 on multiple ribs 7.

[0040] The elastic component further includes a shaft 8, and the elastic element 4 is mounted on the base 1 via the shaft 8. The elastic element 4 is an elastic ring formed by an elastic rope, with one end of the elastic ring wrapped around the connecting shaft 5 and the other end wrapped around the shaft 8. The two ends of the elastic rope can be fused together to form the elastic ring, or the two ends of the elastic rope can be fixed in other ways. There are two elastic components, each located at one end of the pedal assembly 3. Specifically, the two elastic components are located at the left and right ends of the pedal assembly 3, respectively. The shaft 8 can be welded to the base 1, or it can be fixed to the base 1 by threads.

[0041] The pedal assembly 3 has two guide rails 2, with the elastic component positioned between them. The two guide rails 2 are located on the front and rear sides of the pedal assembly 3, respectively. The guide rails 2 are welded to the base 1. Alternatively, the guide rails 2 and base 1 can be integrally formed. The pedal assembly 3 can have four wheels, each connected to the pedal assembly 3 via a rotational mechanism. Two wheels are located on each of the front and rear sides of the pedal assembly 3. The two wheels on the front side of the pedal assembly 3 engage with the guide rails 2 on the front side, and the wheel on the rear side of the pedal assembly 3 engages with the guide rails 2 on the rear side. This engagement of the wheels with the guide rails 2 ensures that the pedal assembly 3 slides only left and right during sliding, without any forward or backward wobbling. This allows the connecting shaft 5 to be positioned using the friction between the connecting shaft 5 and the sidewall of the mounting groove 6.

[0042] The working principle of this embodiment:
