[0042] Example

[0043] This application provides a non-powered treadmill, such as Figures 1 to 5 As shown, it includes: a support frame 2 and a rolling element 3;

[0044] The support frame 2 has a head end 26 and a tail end 27, and the head end 26 of the support frame 2 is provided with a handrail 1;

[0045] Multiple rolling elements 3 are rotatably connected to the support frame 2, and form a running ramp 30 on the support frame 2. The lowest point of the running ramp 30 is close to or located at the tail end 27.

[0046] The running slope 30 has a variety of different inclines along the direction from the head end 26 to the tail end 27 to provide users with different exercise resistance.

[0047] Understandably, the running slope 30 has a variety of different slopes, that is, different areas with varying elevations, to provide users with different levels of resistance.

[0048] Understandably, different changes in altitude and slope can produce different resistance effects, allowing users to experience more diverse training modes during running, thereby increasing the fun and challenge of the workout.

[0049] Running slope 30 has a variety of different inclines, which can also increase the training intensity of different muscle groups. For example, uphill running can strengthen the leg and hip muscles, while downhill running can enhance the stability and balance of the lower limbs.

[0050] With 30 different inclines on the running surface, users can more effectively adjust the intensity of their workout, conduct high-intensity interval training or other targeted training, and achieve better fitness results.

[0051] In addition, users can choose an incline zone that suits their training level, meeting their personalized experience needs without having to adjust the treadmill's resistance, thus reducing the risk of sports injuries caused by excessively high or low training intensity.

[0052] Specifically, in some embodiments of this application, the support frame 2 is provided with a plurality of connecting parts 23.

[0053] The support frame 2 includes a first support base 21 and a second support base 22, and the two ends of the handrail 1 are respectively connected to the first support base 21 and the second support base 22;

[0054] Understandably, the connection between the support frame 2 and the handrail 1 is simple and stable, which can effectively improve the stability of the treadmill.

[0055] Treadmills do not require power, which not only reduces energy consumption and maintenance costs, but also improves the safety of treadmills. Furthermore, users drive the treadmill with their own physical strength and gravity, which can more effectively exercise the user's leg muscles and improve cardiopulmonary function.

[0056] The first support base 21 and the second support base 22 are respectively provided with multiple connecting parts 23 on opposite sides. All connecting parts 23 on the first support base 21 and all connecting parts 23 on the first support base 22 are arranged at intervals according to an arc-shaped trajectory. One end of each rolling element 3 is rotatably connected to the connecting part 23 located on the first support base 21, and the other end of each rolling element 3 is rotatably connected to the corresponding connecting part 23 located on the second support base 22. After all the rolling elements 3 are set on the support frame 2, they are used to form an arc-shaped running ramp 30.

[0057] On the one hand, by setting multiple connecting parts 23 on the arc track, an arc running slope 30 is formed by connecting the connecting parts and the rolling parts 3, which simplifies the connection process between the rolling parts 3 and the support frame 2. Moreover, the arc running slope 30 of the treadmill can better fit the natural gait of the human body when running, making the user's running experience smoother and more comfortable.

[0058] On the other hand, the rolling element 3 is arranged along an arc-shaped trajectory, which helps to distribute the force on the treadmill, providing more even support, thereby improving overall stability and reducing swaying or instability during running.

[0059] Preferably, all connecting parts 23 are arranged at even intervals along an arc-shaped trajectory, further ensuring that the first support 21 and the second support 22 are evenly distributed under force.

[0060] On the other hand, the curved running incline 30 can also provide better shock absorption, reduce the impact on the knee joint and other joints, and reduce the risk of injury; it can also improve the overall structural coordination and aesthetics of the treadmill, providing a running experience different from traditional treadmills, making the treadmill more innovative and attractive in design.

[0061] Furthermore, such as Figure 2 and Figure 3 As shown, the support frame 2 is provided with a locking member 24, which has a locking groove 241 that matches the shape of the handrail 1 and is used to lock the handrail 1 in the use state.

[0062] The engaging slot 241 of the engaging component 24 can accurately fix the handrail 1, reduce the shaking or displacement of the handrail 1 during use, improve the stability and safety of the overall structure, provide stable support for the user's running, help ensure the user's safety, improve the user's comfort and user experience, and reduce fatigue in the hands or arms.

[0063] The locking groove 241 reduces friction and impact between the handrail 1 and the support frame 2, thus reducing noise generated during treadmill operation. Furthermore, the locking groove 241 design helps to distribute force, reducing the direct impact of the handrail 1 on the support frame 2.

[0064] Furthermore, such as Figure 5 As shown, a locking mechanism 242 for locking the armrest 1 is also connected to the locking member 24;

[0065] The handrail 1 is provided with a locking hole 11 corresponding to the locking mechanism 242. The locking mechanism 242 is used to lock the handrail 1 after being aligned and connected to the locking hole 11.

[0066] The locking mechanism 242 can effectively fix the handrail 1, preventing it from loosening or shifting during use, thereby improving user safety and further reducing the risk of accidents; the locking mechanism 242 also makes the locking process of the handrail 1 quick and easy, improving ease of use.

[0067] Furthermore, the design of the locking mechanism 242 can reduce the loosening of the handrail 1 due to vibration or external force, thereby improving the durability and long-term stability of the treadmill.

[0068] The design of the locking hole 11 and the locking mechanism 242 helps to achieve precise docking between the handrail 1 and the support frame 2, avoiding structural problems caused by poor docking.

[0069] Furthermore, the locking mechanism 242 is also provided with an elastic element (not shown in the figure);

[0070] On the one hand, the elastic element can effectively absorb and buffer the impact caused by external force or vibration, reduce damage to the locking mechanism 242, and improve the durability of the overall structure;

[0071] On the other hand, the elastic element can provide additional fixing force, further enhancing the stability of the handrail 1 and preventing it from loosening or shifting during use;

[0072] On the other hand, the elastic element also helps to realize the automatic locking and reset function of the locking mechanism 242, thus optimizing the user experience.

[0073] Specifically, in some embodiments of this application, the elastic element is a spring;

[0074] Furthermore, such as Figure 3 As shown, the cross-sectional shape of the engaging member 24 includes a hook shape.

[0075] The cross-sectional shape of the latching member 24, including a hook shape, can provide a larger contact area, making the latching member 24 more securely locked when connected, thereby increasing the stability and security of the connection.

[0076] The hook-shaped design can provide a counterforce when subjected to some external force, effectively preventing the handrail 1 from accidentally falling off when subjected to external force or vibration. The hook-shaped structure can better grab or hang the handrail 1, enhancing the reliability of the connection.

[0077] Furthermore, such as Figure 3 and Figure 4 As shown, the rolling element 3 is provided with one or more rolling parts;

[0078] Preferably, the rolling element 3 is provided with two rolling parts, specifically including a first rolling part 31 and a second rolling part 32;

[0079] Understandably, the first rolling part 31 and the second rolling part 32 can optimize the movement mode of the treadmill, making the movement mode of the treadmill more flexible. The user's left foot can step on the first rolling part 31 and the user's right foot can step on the second rolling part 32, so that the movement of the rolling part 3 is more matched with the user's gait, improving the user's running comfort and safety.

[0080] Furthermore, such as Figure 4 As shown, each rolling element 3 is also provided with a filler 311 for counterweighting;

[0081] Understandably, the presence of padding 311 can appropriately increase the weight of each rolling element 3, enhance the stability of each rolling element 3, and reduce the possibility of tilting during use to a certain extent; padding 311 can also help absorb impact and vibration, provide a smoother running experience, and reduce pressure on joints.

[0082] Therefore, by providing a filler 311 for counterweight in each rolling element 3, the stability of the treadmill can be further improved and the safety performance of the treadmill can be enhanced.

[0083] Furthermore, such as Figure 1 As shown, a mobile component 4 is also provided;

[0084] The moving component 4 includes a rotating shaft 41 and a moving wheel 42, and through holes 210 are respectively opened at the bottom of the first support base 21 and the second support base 22;

[0085] The two ends of the rotating shaft 41 pass through different through holes 210 and are coaxially connected to different moving wheels 42.

[0086] By providing through holes 210 at the bottom of the first support base 21 and the second support base 22, and using the combination of the rotating shaft 41 and the moving wheel 42, it can be ensured that the rotating shaft 41 rotates stably between different support bases; the first support base 21 and the second support base 22 provide uniform support force, making the treadmill move more smoothly; the moving wheel 42 connected by the rotating shaft 41 can balance the load, reduce frictional resistance, and improve the smoothness and efficiency of movement; thus improving the portability of the treadmill.

[0087] Furthermore, such as Figure 1 and Figure 3 As shown, a shock absorber 12 is also provided at the connection between the handrail 1 and the support frame 2.

[0088] The shock absorber 12 can effectively absorb and mitigate vibration and impact, thereby reducing the mutual influence and fatigue damage between the handrail 1 and the support frame 2, protecting the treadmill from damage, and helping to extend the service life of the treadmill.

[0089] The shock absorber 12 can also reduce the vibration and shock felt by the user during use, thereby improving the comfort of use; and the shock absorber 12 can also reduce the noise caused by vibration, further optimizing the user experience.

[0090] Furthermore, such as Figure 2 and Figure 3 As shown, the handrail 1 is rotatably connected to the support frame 2. The end of the support frame 2 away from the handrail 1 is provided with a fixing piece 25 to fix the handrail 1 in the folded state.

[0091] The fastener 25 can effectively secure the handrail 1 in the folded state, preventing the handrail 1 from being accidentally unfolded or moved when not in use, thus keeping the treadmill neat and orderly.

[0092] Furthermore, when folded, the fastener 25 ensures that the handrail 1 will not shake or fall off during handling or storage, thereby reducing the risk of injury or damage to the user or the treadmill. By folding and securing the handrail 1, the treadmill can occupy less space during storage or transportation.

[0093] The fastener 25 also helps reduce the movement and friction of the armrest 1 in the folded state, prevents damage caused by improper placement or impact, and extends the service life of the equipment.

[0094] Furthermore, such as Figures 1 to 3 As shown, the first support seat 21 and the second support seat 22 are recessed towards the running slope 30 to form an arc-shaped profile.

[0095] The curved contour design can better adapt to different types of ground and surface unevenness, thereby improving the treadmill's adaptability in different environments;

[0096] The curved contour can provide a smaller contact area, but this contact method can concentrate the pressure on a few points, which helps to stabilize the treadmill and prevent the treadmill from becoming unstable or shaking during exercise.

[0097] The curved profile can also reduce wear and tear on the bottom of the treadmill from the ground, extending the treadmill's lifespan. At the same time, the curved design reduces contact with the ground, allowing for smoother water flow at the bottom of the machine, which is beneficial for treadmills used in water environments and reduces the direct impact of water flow on the treadmill.

[0098] Furthermore, such as Figure 2 As shown, the handrail 1 is also provided with anti-slip texture 13.

[0099] The anti-slip texture 13 effectively increases friction when gripping, preventing the palm from slipping during use and reducing the risk of accidental falls. When running or engaging in other sports, the anti-slip texture 13 on the handrail 1 helps users maintain a stable grip, thereby enhancing the stability and safety of the exercise. The anti-slip texture 13 design can prevent the palm from slipping due to water flow, making it more comfortable to hold the handrail 1 for a long time and avoiding hand fatigue or discomfort caused by slipping. It further adapts to the aquatic environment and meets the needs of use in aquatic scenarios.

[0100] Specifically, in some embodiments of this application, the running ramp 30 is concave downwards, and generally exhibits a downward trend from the head end 26 to the tail end 27 of the support frame 2, that is, from the end of the support frame 2 closer to the handrail 1 to the end farther away from the handrail 1, it exhibits a downward trend.

[0101] The concave design of the running ramp 30 allows the foot to fit more stably against the running ramp 30, effectively increasing the usable range of the running ramp 30 and improving the space utilization of the running ramp 30; it reduces slippage and instability during exercise, and the gradually lowered design helps the foot transition naturally, reducing the impact when stepping, providing more support and cushioning, and further making exercise more comfortable.

[0102] The embodiments of this application have at least the following beneficial effects:

[0103] This application provides a non-powered treadmill that offers diverse resistance levels without requiring adjustments to the running belt. It also provides a good pedaling feel and smooth movement, optimizing the user experience. Specifically, all the rolling elements 3 are arranged at intervals along an arc-shaped trajectory to form a running slope 30. Different areas with varying slopes provide diverse resistance levels to meet individual user needs without requiring adjustments to the overall resistance or tension of the treadmill. The arc-shaped running slope 30 also optimizes the pedaling feel, enhancing the smoothness and comfort of the user's running experience.

[0104] Those skilled in the art will understand that the modules in the apparatus of the implementation scenario can be distributed within the apparatus of the implementation scenario as described, or they can be located in one or more apparatuses different from this implementation scenario, with corresponding changes. The modules of the above-described implementation scenario can be combined into one module, or they can be further divided into multiple sub-modules.

[0105] The serial numbers in this application are for descriptive purposes only and do not represent the superiority or inferiority of the implementation scenario.

[0106] The above disclosures are only a few specific implementation scenarios of this application. However, this application is not limited to these. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this application.
