[0049] Example

[0050] This application provides a foldable, non-powered treadmill for use in aquatic environments, such as... Figures 1 to 8 As shown, it includes: support component 1 and running mechanism 2;

[0051] Specifically, in some embodiments of this application, the support component 1 is at least partially made of corrosion-resistant material or has an anti-corrosion coating on its surface, which has strong anti-corrosion ability to meet the needs of frequent and long-term use in water.

[0052] More specifically, in some embodiments of this application, the support component 1 may be made of stainless steel.

[0053] The running mechanism 2 is rotatably connected to the inner side of the support component 1 to enable the running mechanism 2 to switch between the stowed state and the unfolded state.

[0054] When the running mechanism 2 is in its stowed state, the projection of its center of gravity on the ground lies within the area enclosed by the support component 1 on the ground, such as... Figure 4 As shown, the area enclosed by the support component 1 and the dashed line is the area bounded by the support component 1 on the ground.

[0055] Preferably, the projection of the center of gravity onto the ground is located in the central region within the area enclosed by the support component 1 on the ground, in order to achieve better stability.

[0056] When the running mechanism 2 is in the unfolded state, the angle formed between the plane on which the running surface of the running mechanism 2 is located and the horizontal plane is an acute angle.

[0057] Understandably, when the running mechanism 2 is stowed, its center of gravity is located within the range of the support component 1, which helps to save space. Furthermore, after the running mechanism 2 is stowed, the positional relationship between the running mechanism 2 and the support component 1 is relatively stable and is not prone to shifting, thus making it less likely to be damaged due to shaking.

[0058] In its unfolded state, the angle between the running surface of the running mechanism 3 and the horizontal plane is an acute angle, which helps to optimize the user's running posture, making the exerciser's body posture more natural, reducing pressure on the knees and joints, and improving running comfort and effectiveness.

[0059] Furthermore, it also includes handrails 3;

[0060] Handrail 3 is connected to support component 1, and support component 1 is connected to running mechanism 2;

[0061] The running mechanism 2 includes a running belt 23, a first rolling element 21, a second rolling element 22, a support plate 24, a first frame element 25, and a second frame element 26;

[0062] A support plate 24 is provided between the first rolling element 21 and the second rolling element 22. The height of one end of the support plate 24 is not higher than the height of the first rolling element 21, and the height of the other end of the support plate 24 is not higher than the height of the second rolling element 22. Furthermore, the bottom surface of one end of the support plate 24 is not lower than the bottom surface of the first rolling element 21, and the bottom surface of the other end of the support plate 24 is not lower than the bottom surface of the second rolling element 22. The support plate 24 includes one or more elastic component plates 241, and the support plate 24 is mounted on the first frame member 25 and the second frame member 26.

[0063] Understandably, in some embodiments of this application, a support plate 24 is provided between the first rolling element 21 and the second rolling element 22. The height of one end of the support plate 24 is not higher than the height of the first rolling element 21, and the height of the other end of the support plate 24 is not higher than the height of the second rolling element 22. This can support the running belt 23, enhance the stability of the overall structure of the treadmill, and also reduce the friction between the support plate 24 and the running belt 23, making the movement of the running belt 23 smoother. The support plate 24 includes one or more elastic component plates 241 to adapt to the usage requirements of the aquatic environment and enhance the safety of the treadmill.

[0064] In some other embodiments of this application, when the support plate 24 includes multiple component plates 241, the elastic component plates 241 can provide corresponding cushioning and support according to the user's weight and gait changes, have good shock absorption performance, can reduce the impact of the treadmill on the user's joints, improve user comfort, and optimize the user's experience.

[0065] The support plate 24 is composed of multiple elastic component plates 241, and each component plate 241 can move independently, with a relatively good degree of freedom, and can adapt to different paces and foot landing methods. This flexibility enables the support plate 24 to remain stable during dynamic movement, further enhancing the user's sports experience.

[0066] In addition, the elastic component plate 241 can absorb some of the vibrations generated during exercise, thereby reducing noise caused by running or walking. The component plate 241 moves independently and can be combined to help provide overall stable support, effectively distributing the user's weight, thereby improving the stability and safety of the treadmill.

[0067] The running belt 23 is wrapped around the first rolling element 21, the second rolling element 22 and the support plate 24. The first rolling element 21 and the second rolling element 22 are both located between the first frame element 25 and the second frame element 26, and are rotatably connected to the first frame element 25 and the second frame element 26 respectively. The first frame element 25 and the second frame element 26 are respectively connected to the end of the support assembly 1 away from the handrail 3.

[0068] Understandably, the above-mentioned structural design can further improve the overall stability of the treadmill, so that the running belt 23 can maintain balance during use, reduce swaying and lateral tilting, and make the movement of the running belt 23 more stable.

[0069] Furthermore, such as Figure 6 As shown, the running mechanism 2 is also equipped with a tension adjustment component 4;

[0070] Both the first rolling element 21 and the second rolling element 22 include a rolling shaft 211 and a cylinder 221; the two ends of the rolling shaft 211 are respectively provided with adjustment holes 2111;

[0071] The first frame member 25 and the second frame member 26 are respectively provided with mounting seats 251. The mounting seats 251 have through holes 2512 and adjustment grooves 2513. The two ends of the rolling shaft 211 are respectively connected to different mounting seats 251. The tension adjustment member 4 passes through the through holes 2512 and adjustment holes 2111 in sequence, so that the rolling shaft 211 can move in the adjustment grooves 2513 to adjust the tension of the running belt 23.

[0072] Understandably, by adjusting the positional relationship between the tension adjustment component 4 and the adjustment hole 2111, and thus adjusting the position of the rolling shaft 211 within the adjustment groove 2513, precise control of the tension of the running belt 23 can be achieved. It can also adjust the positions of the first rolling component 21 and the second rolling component 22 to meet the user's personalized needs for the tension of the running belt 23, adapt to the user's personal running habits and comfort, and thus achieve the best running effect.

[0073] Specifically, in some embodiments of this application, the tension adjustment member 4 is a bolt structure and the adjustment hole 2111 is a screw hole structure; of course, the specific structure of the tension adjustment member 4 and the adjustment hole 2111 is not limited here.

[0074] Furthermore, such as Figure 3 and Figure 7As shown, preferably, in some embodiments of this application, the support plate 24 is composed of multiple pieces, all of which are distributed at intervals along the length of the running belt 23, and an elastic element 5 is provided between adjacent pieces 241.

[0075] Understandably, all the component plates 241 are evenly spaced along the length of the running belt 23, which helps to achieve more uniform support, reduce friction between the running belt 23 and the support plate 24, improve stability, make the elasticity and shock absorption of the running belt 23 more evenly distributed, provide a more comfortable running experience, and reduce the impact on the feet and joints.

[0076] Elastic elements 5 are provided between adjacent component plates 241, making the running belt 23 more elastic and adaptable. This can further optimize the shock absorption effect, reduce pressure on the joints, and make the user's gait more natural and the movement smoother, thus improving the overall running experience. It can also effectively reduce the noise and vibration generated by the movement of the running belt 23, making the treadmill run more quietly and providing users with a quieter exercise environment.

[0077] Preferably, the component plate 241 is an elastic component plate 241.

[0078] Alternatively, the elastic element 5 can be implemented using rubber, elastic plastic, or a spring. Of course, there are no restrictions on the specific implementation of the elastic element 5.

[0079] Furthermore, such as Figure 1 and Figure 4 As shown, the support assembly 1 includes a first support member 11, a second support member 12 and a connector 13. The handrail 3 is connected to the first support member 11 and the second support member 12 respectively, and the connector 13 is connected to the end of the first support member 11 and the second support member 12 away from the handrail 3 respectively.

[0080] The inner sides of the first support member 11 and the second support member 12 are respectively provided with rotating connecting parts 14, which are located between the handrail 3 and the connecting member 13; so that the running mechanism 2 is mounted on the support assembly 1 and forms an angle with the ground.

[0081] The rotating connection 14 allows for a certain degree of rotational freedom between the handrail 3 and the support assembly 1, which enables the treadmill to better adapt to different spatial layouts when stored or used. The treadmill can be folded or repositioned when not in use to save space.

[0082] The connection design between the handrail 3 and the support component 1 improves the safety of the treadmill, effectively enhances its stability and load-bearing capacity, and allows the handrail 3 to be firmly connected to the support component 1, helping users to obtain better support and safety during exercise.

[0083] The above structural design creates a certain angle between the running belt 23 and the support component 1, which can simulate the effect of running uphill, increase resistance during running, enhance the intensity of leg muscle training, and improve the aerobic exercise effect, thereby improving training efficiency. It can also help users maintain a more natural running posture, promote the development of a forefoot landing running style, reduce the impact on the knees, reduce the risk of injury, and better exercise the calf and gluteal muscles.

[0084] Furthermore, such as Figure 4 As shown, the connector 13 includes a U-shaped structure 131, the opening of which faces the running mechanism 2.

[0085] The connector 13 is U-shaped, and the opening of the U-shaped structure 131 faces the running mechanism 2, which can more tightly surround the front section of the running mechanism 2, achieve a good support effect for the running mechanism 2, improve the stability of the overall structure, reduce the vibration and instability generated during running, and thus provide a safer user experience.

[0086] In addition, the U-shaped structure 131 with its opening facing the running mechanism 2 allows for a more compact and rational arrangement of the treadmill's internal components, optimizing space utilization.

[0087] Furthermore, such as Figure 1 and Figure 4 As shown, a fixing part 34 is provided on the side of the first support member 11 and / or the second support member 12 near the handrail 3. The fixing part 34 is used to connect the end of the running mechanism 2 away from the support component 1 after the running mechanism 2 is folded, so as to fix the running mechanism 2.

[0088] When the running mechanism 2 is folded, the fixing part 34 helps to firmly fix the end of the running mechanism 2 away from the support component 1 in the proper position, preventing the treadmill from moving or becoming unstable after folding, enhancing the stability of the treadmill, and thus improving the safety of the treadmill when storing it. By folding and fixing the running mechanism 2 in place by the fixing part 34, the treadmill can be folded more compactly and take up less space.

[0089] Furthermore, such as Figure 4 As shown, the handrail 3 includes a first handrail part 31, a second handrail part 32 and a third handrail part 33;

[0090] One end of the first handrail 31 is connected to the first support member 11 and the second handrail 32, and the other end of the first handrail 31 is connected to the second support member 12 and the third handrail 33.

[0091] The angle between the connection between the second handrail 32 and the support assembly 1 and the angle between the connection between the third handrail 33 and the support assembly 1 are between 30 degrees and 50 degrees.

[0092] The shapes of the second handrail 32 and the third handrail 33 include arc shapes.

[0093] The curved design of the second handrail 32 and the third handrail 33, with the angle between the second handrail 32 and the support component 1 and the angle between the third handrail 33 and the support component 1 being between 30 degrees and 50 degrees, is more ergonomic and can better fit the user's natural grip posture, reducing hand fatigue during long-term use and improving comfort.

[0094] The design of the first handrail 31, the second handrail 32, and the third handrail 33 provides support points at different locations, offering a more natural and comfortable grip angle. This allows users to use the different positions of the handrail 3 more easily and freely while exercising on the treadmill, better adjust their hand posture, obtain better stability support, and enhance the overall user experience.

[0095] The sturdy handrail design also helps users maintain balance, reducing the risk of falls or slips and improving safety during exercise.

[0096] Furthermore, such as Figure 1 As shown, an auxiliary connection part 15 is also provided. The auxiliary connection part 15 is located between the support component 1 and the first frame member 25 and the second frame member 26 to enhance the connection stability between the support component 1 and the running mechanism 2.

[0097] The auxiliary connection part 15 strengthens the connection between the support component 1 and the first frame member 25 and / or the second frame member 26, reducing the shaking or displacement of the support component 1 during use, further enhancing the stability of the overall structure of the treadmill. The auxiliary connection part 15 also helps to distribute the load more evenly, reduce the pressure on each connection point, reduce friction and wear, effectively improve the load-bearing capacity of the treadmill, support higher usage intensity, and thus extend the service life of the treadmill. In addition, the auxiliary connection part 15 also reduces safety hazards caused by loose connections or component failure.

[0098] Furthermore, such as Figure 5 As shown, the bottom of the running mechanism 2 is also provided with several limiting parts 6, which are distributed along the length of the first frame member 25 and / or the second frame member 26 to limit the vibration range of the running belt 23.

[0099] The limiting part 6 effectively restricts the vibration range of the running belt 23, reduces the shaking generated during operation, improves the stability of the movement, makes running more comfortable, and enhances the overall exercise experience. The limiting part 6 also limits vibration, reduces the risk of deviation of the running belt 23, reduces accidents or injuries that may be caused by abnormal movement of the running belt 23, and also reduces wear and tear on the running belt 23 and other components, thereby extending the service life of the treadmill.

[0100] Furthermore, such as Figure 5 As shown, the first frame member 25 and the second frame member 26 are respectively provided with adjustable height support pads 7 at the ends away from the support assembly 1.

[0101] The support foot pads 7 enhance the stability of the treadmill on the ground, effectively preventing wobbling or tilting during use. Support foot pads 7 typically have some adjustment capabilities to adapt to uneven ground, helping the treadmill maintain a level position and thus improving the user experience. Support foot pads 7 also reduce structural stress caused by uneven contact and minimize direct contact between the running mechanism 2 and the bottom surface, thereby protecting the bottom and support structure of the treadmill and reducing wear and potential malfunctions.

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

[0103] This application provides a foldable, non-powered treadmill that offers good storage convenience, making the treadmill more stable after storage, less prone to damage, and enhancing safety during use. It also enhances safety when used underwater and improves structural stability, while providing good smoothness and flexibility during use.

[0104] Specifically, a support plate 24 is provided, which supports the running belt 23 and enhances the stability of the overall structure of the treadmill. The support plate 24 includes one or more elastic component plates 241, which increases the diversity of the form of the support plate 24 and can more flexibly adapt to the pressure changes when the user runs, making the movement of the running belt 23 smoother. The height of one end of the support plate 24 is not higher than the height of the first rolling element 21, and the height of the other end of the support plate 24 is not higher than the height of the second rolling element 22, which helps to reduce the friction between the support plate 24 and the running belt 23, making the operation of the running belt 23 smoother.

[0105] 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.

[0106] The serial numbers in this application are for descriptive purposes only and do not represent the superiority or inferiority of the implementation scenario.

[0107] 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.
