Description

A sliding storage treadmill

[0001] This application claims priority to Chinese Patent Application No. 202411744629.7, filed on December 1, 2024, entitled "A Sliding Storage Treadmill", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of fitness equipment technology, specifically a sliding storage treadmill. Background Technology

[0003] Treadmills are a type of fitness equipment primarily used for indoor running or walking exercises. They consist of a running board and a running belt. The running belt is mounted on the running board and moves under the drive of an electric motor, simulating the effect of running on the ground. Treadmills are usually equipped with a control panel to adjust speed parameters to suit different training needs and intensities. Foldable treadmills, on the other hand, are fitness equipment designed to save space. These treadmills can be easily folded up when not in use, reducing their footprint and making them convenient to store.

[0004] This invention provides a novel sliding storage treadmill. The treadmill has different storage and folding methods, which can simultaneously store the running belt during storage, preventing the running belt from becoming loose and easily falling off after the running board is folded. Summary of the Invention

[0005] This invention provides a novel sliding treadmill that allows for simultaneous storage of the running belt during treadmill folding, preventing the belt from becoming loose and prone to detachment after the running board is folded. Furthermore, this sliding treadmill also addresses the problem that if the running belt is prematurely retracted by the anti-wrinkle mechanism during the sliding folding process of the second running board relative to the first running board, it can cause the running belt to be stretched, affecting its lifespan.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sliding storage treadmill, including a first running board and a second running board, the first running board and the second running board being movably connected, and a running belt being sleeved on the surface of the first running board and the second running board, the running belt maintaining tension when the first running board and the second running board are horizontally connected.

[0007] Optionally, at least one first folding rod is rotatably connected to each of the front and rear sides of the first running board, the right end of the first folding rod is rotatably connected to the second running board, and at least one second folding rod is rotatably connected to each of the front and rear sides of the second running board, the left end of the second folding rod is rotatably connected to the first running board.

[0008] Optionally, an anti-wrinkle mechanism is installed at the bottom of the inner wall of the second running board. The top of the anti-wrinkle mechanism is movably connected to the outer wall of the running belt to ensure that the running belt maintains tension during the upward sliding and retraction of the second running board.

[0009] Optionally, to prevent the running belt from being overstretched during the rising of the second running board, the anti-wrinkle mechanism is configured to include a fixing member and a first rotating member. The fixing member and the first rotating member are rotatably connected by a connector. When the second running board is folded and stored, the first rotating member rotates relative to the fixing member, causing the running belt to be stored and preventing wrinkles from forming on the running belt.

[0010] Optionally, a limiting structure is further provided at the connection between the first rotating component and the fixed component. This limiting structure limits the angle at which the first rotating component rotates. More specifically, the limiting structure limits the angle between the first rotating component and the fixed component to no less than 90 degrees. The fixed component and its set angle are used to prevent the first rotating component from falling perpendicularly to the first running board during the treadmill's storage process, thus avoiding impact damage to the first running board. Furthermore, it also prevents the angle between the first rotating component and the fixed component from being less than 90 degrees, which would cause the first rotating component to fold backward and fail to achieve the desired effect of properly storing the running belt.

[0011] Optionally, the fasteners are installed on both sides of the second running board. Preferably, the fasteners are installed at a preset angle to the horizontal plane of the second running board. More preferably, the angle between the fasteners and the horizontal plane of the second running board is 4-8 degrees. Setting the fasteners at a preset angle to the second running board can reduce friction and damage between the running belt and the fasteners, and extend the service life of the equipment.

[0012] Optionally, the connecting member for connecting the fixed member and the first rotating member includes an elastic device, which includes, but is not limited to, a torsion spring, a spring, or a leaf spring. More specifically, the elastic device is an elastic hinge. The elastic device allows the first rotating member to be in a substantially horizontally open state relative to the fixed member.

[0013] Optionally, a folding motor is fixedly installed on the inner wall of the first running board, and the output shaft of the folding motor is fixedly connected to the left end of the second folding rod for rotating the second folding rod and the second running board.

[0014] Optionally, a first support plate is fixedly connected to the top of the inner wall of the first running board, and a second support plate is fixedly connected to the top of the inner wall of the second running board. The first support plate and the second support plate are movably connected, and the tops of the first support plate and the second support plate are slidably connected to the top of the inner wall of the running belt to support the running belt.

[0015] Optionally, a drive roller is rotatably connected to the left side of the inner wall of the first running board, and a drive motor is fixedly installed on the left side of the inner wall of the first running board. A transmission wheel is fixedly sleeved on the output shaft of the drive motor and the front end of the drive roller. A belt is connected to the transmission wheel. The surface of the drive roller is movably connected to the inner wall of the running belt to drive it, start the drive motor, and realize the automatic storage function of the treadmill.

[0016] Optionally, to avoid contact between the drive motor and the running belt, which could cause continuous friction and damage during operation, a guide roller is rotatably connected to the bottom of the inner wall of the first running board. The bottom of the guide roller protrudes from the lower surface of the drive motor and is movably connected to the inner wall of the running belt.

[0017] Optionally, a correction roller is rotatably connected to the right side of the inner wall of the second running board. The surface of the correction roller is provided with anti-slip texture, and the anti-slip texture is movably connected to the inner wall of the running belt. The correction roller with anti-slip texture has the function of correcting the running belt.

[0018] Optionally, a frame is fixedly installed on the left side of the first running board, a control panel is fixedly installed on the top of the frame, and handrails are fixedly connected to the front and rear sides of the top of the inner wall of the frame, so that users can stabilize their bodies and ensure their safety when using the treadmill.

[0019] Optionally, at least two casters are installed on the left side of the first running board of the sliding storage treadmill so that the user can easily change the position of the treadmill when it is moved after being stored.

[0020] Optionally, both the first running board and the bottom of the second running board are fixedly connected with support legs, and the number of support legs is at least one.

[0021] Optionally, a cleaning mechanism is fixedly installed on the right side of the second running board, which cleans impurities from the surface of the running belt.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention, by setting a drive motor, can easily drive the drive roller to rotate. The belt is installed on the transmission wheel. The drive motor drives the drive roller to rotate through the transmission wheel and belt. During the rotation of the drive roller, the running belt rotates on the first and second running boards to assist the user in running. The correction roller and guide roller support the rotating running belt. The surface of the correction roller is provided with anti-slip texture, which increases the friction between the correction roller and the running belt. When the correction roller contacts the running belt, a greater friction is generated between the two. This increased friction helps to more effectively transmit the lateral correction force, making it easier for the running belt to be guided back to the correct position.

[0024] 2. By incorporating a folding motor, this invention facilitates the sliding and folding of the first and second running boards. The output shaft of the folding motor drives the second folding rod to rotate. During the rotation of the second folding rod, the second running board slides to the top of the first running board. As the second running board rotates, the first folding rod rotates synchronously, thereby improving the stability of the second running board during rotation. After the second running board is folded on top of the first running board, the running belt is folded synchronously. The anti-wrinkle mechanism pushes the running belt to fold it in, preventing wrinkles from forming on the running belt after the running board is folded.

[0025] 3. The present invention, by setting up a cleaning mechanism, can facilitate the cleaning of impurities on the surface of the running belt.

[0026] 4. By setting support legs, the present invention can easily support the bottom of the first and second running boards, so that they can be placed stably on the ground. By setting the frame, the control panel can be easily supported and fixed. By setting the control panel, the operating parameters of the treadmill can be easily adjusted. Attached Figure Description

Detailed Implementation

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0038] In one example of this application, as shown in Figures 1-3, a sliding storage treadmill includes a first running board 1 and a second running board 2. The first running board 1 and the second running board 2 are movably connected. Running belts 5 are fitted on the surfaces of the first running board 1 and the second running board 2. At least one first folding rod 11 is rotatably connected to the upper part of the front and rear sides of the first running board 1. The right end of the first folding rod 11 is rotatably connected to the second running board 2. At least one second folding rod 12 is rotatably connected to the lower part of the front and rear sides of the second running board 2. The left end of the second folding rod 12 is rotatably connected to the first running board 1.

[0039] Optionally, as shown in Figure 4, in this application, the first running plate 1 is longer than the second running plate 2 in front-to-back length, so that the second running plate 2 can be completely retracted. In addition, the first folding rod 11 and the second folding rod 12 on the same side are arranged in a parallelogram on the first running plate 1 and the second running plate 2 to ensure the stability of the second running plate 2 during the sliding process.

[0040] In one embodiment of the present invention, an anti-wrinkle mechanism 18 is installed at the bottom of the inner wall of the second running board 2. The anti-wrinkle mechanism 18 is movably connected to the outer wall of the running belt 5 to ensure that the running belt 5 maintains tension during the sliding and folding process of the second running board 2. When the treadmill is folded and folded, the folding motor 16 facilitates the sliding and folding of the first running board 1 and the second running board 2. The output shaft of the folding motor 16 drives the second folding rod 12 to rotate. During the rotation of the second folding rod 12, the second running board 2 slides to the top of the first running board 1. During the rotation of the second running board 2, the first folding rod 11 rotates synchronously to improve the stability of the second running board 2 during rotation. After the second running board 2 is folded and folded on top of the first running board 1, the anti-wrinkle mechanism 18, while sliding with the second running board, drives the running belt 5 to fold and fold, preventing wrinkles from forming after the running belt 5 is folded.

[0041] During production research, the inventors discovered that during the initial upward retraction of the second running board 2, specifically when the angle between the second folding rod 12 and the horizontal direction is greater than 0 degrees and less than or equal to 45 degrees, the required circumference of the running belt 5 exceeds the circumference required for normal operation of the treadmill, resulting in the running belt being stretched. If the anti-wrinkle mechanism 18 is an integral flat plate fixed to the second running board 2 at a preset angle, its forward-extending front end will contact the running belt 8, causing the running belt 5 to be forcibly pushed out, resulting in overstretching and potential damage to the running belt 5, affecting its service life. Therefore, in one embodiment of this application, as shown in Figures 6-9, the anti-wrinkle mechanism 18 includes a fixing member 1801 and a first rotating member 1802. The fixing member 1801 and the first rotating member 1802 are rotatably connected by a connecting member 1804. The length of the first rotating member is longer than the length of the fixing member. When the second running board 2 is folded and retracted, the first rotating member 1802 can rotate relative to the fixing member 1801. During the ascent of the second running board 2, the first rotating component 1802 droops slightly to the lower left, preventing it from folding or pulling the running belt 5 and thus avoiding the aforementioned overstretching problem. When the angle between the second folding rod 12 and the horizontal direction is greater than 45 degrees, the first rotating component 1802 slides into contact with the running belt 5, maintaining tension on the running belt 5 and causing it to be retracted, preventing it from becoming loose or wrinkled. When the first running board 1 and the second running board 2 are completely overlapped and retracted, the first rotating component 1802 rotates under the action of the upper and lower running boards until it is basically horizontal with the fixing component 1801, so that the running belt 5 is properly retracted. Those skilled in the art will understand that the aforementioned angles will vary depending on the setting position and length of the first and second folding rods, and the aforementioned embodiment is only described as one implementation scheme.

[0042] In one embodiment of this application, a limiting structure 1803 is further provided at the connection between the first rotating member 1802 and the fixed member 1801. The limiting structure 1803 is used to limit the angle 22 between the first rotating member 1802 and the fixed member 1801 when the first rotating member 1802 rotates downward to be no less than 100 degrees and no more than 180 degrees. The limiting structure and its set angle are used to prevent the first rotating member from falling perpendicularly to the first running board 1 during the treadmill's storage process, thus avoiding impact damage to the first running board 1. In addition, it also prevents the first rotating member from folding backward when the angle between the first rotating member and the fixed member is less than 100 degrees, thus failing to achieve the effect of fully storing the running belt.

[0043] In one embodiment of this application, as shown in FIG9, the fixing member 1801 is fixedly installed on both sides of the second running board by a mounting bracket. Optionally, the fixing member 1801 is set at a certain angle to the horizontal plane of the second running board 2. Optionally, the included angle 23 is about 4-8 degrees. During the process of the second running board rising and sliding and folding above the first running board, since the fixing member 1801 is fixed to the second running board 2, the running belt 5 forms a certain angle with the left side of the fixing member 1801. If the fixing member 1801 and the second running board 2 are set horizontally, the back-and-forth friction between the running belt 5 and the fixing member 1801 will increase, affecting the service life of the running belt 5. Therefore, setting the fixing member 1801 and the second running board 2 at a preset angle can facilitate the passage and rotation of the running belt 5, reduce the friction and damage between the running belt 5 and the fixing member 1801, and extend its service life.

[0044] Furthermore, the connecting member 1804 for connecting the fixing member 1801 and the first rotating member 1802 includes an elastic device, which includes, but is not limited to, a torsion spring, a spring, or a spring sheet. More specifically, the elastic device is an elastic hinge. The elastic device allows the first rotating member to be in a substantially horizontally open state relative to the fixing member.

[0045] Furthermore, when the first rotating member 1802 and the fixing member 1801 are connected in a horizontal state, their horizontal diameter is just right to fit and accommodate the excess running belt after the running board is folded, thus preventing the running belt from becoming loose or wrinkled.

[0046] Furthermore, a correction roller 14 is rotatably connected to the right side of the inner wall of the second running board 2. The surface of the correction roller 14 is provided with anti-slip texture 13, which is movably connected to the inner wall of the running belt 5. Furthermore, a folding motor 16 is fixedly installed on the inner wall of the first running board 1. The output shaft of the folding motor 16 is fixedly connected to the left end of the second folding rod 12 for rotating the second folding rod 12 and the second running board 2.

[0047] Furthermore, a first support plate 15 is fixedly connected to the top of the inner wall of the first running board 1, and a second support plate 21 is fixedly connected to the top of the inner wall of the second running board 2. The first support plate 15 and the second support plate 21 are movably connected, and the tops of the first support plate 15 and the second support plate 21 are slidably connected to the top of the inner wall of the running belt 5 to support the running belt 5.

[0048] Furthermore, a drive roller 8 is rotatably connected to the left side of the inner wall of the first running board 1, and a drive motor 9 is fixedly installed on the left side of the inner wall of the first running board 1. A transmission wheel 10 is fixedly sleeved on the output shaft of the drive motor 9 and the front end of the drive roller 8. A belt is connected to the transmission wheel 10 for transmission. The surface of the drive roller 8 is movably connected to the inner wall of the running belt 5 to drive it.

[0049] Furthermore, a guide roller 17 is rotatably connected to the bottom of the inner wall of the first running board 1, and the bottom of the guide roller 17 is movably connected to the bottom of the inner wall of the running belt 5.

[0050] As shown in Figures 4-5, after the sliding storage is completed, the second running board 2 moves to the top of the first running board 1 to reduce the area occupied by the treadmill. After storage, the treadmill can be stood up. Refer to Figure 5 for the standing state. After standing up, the area occupied can be further reduced for storage.

[0051] When a user uses the treadmill, the drive motor 9 facilitates the rotation of the drive roller 8. The belt is mounted on the transmission wheel 10. The drive motor 9 drives the drive roller 8 to rotate through the transmission wheel 10 and the belt. During the rotation of the drive roller 8, the running belt 5 rotates on the first running board 1 and the second running board 2 to assist the user in running. The correction roller 14 and the guide roller 17 support the rotating running belt 5. The surface of the correction roller 14 is provided with anti-slip texture 13, which increases the friction between the correction roller 14 and the running belt 5. When the correction roller 14 contacts the running belt 5, a greater friction is generated between them. This increased friction helps to more effectively transmit the lateral correction force, making it easier for the running belt 5 to be guided back to the correct position.

[0052] Furthermore, a frame 7 is fixedly installed on the left side of the first running board 1, a control panel 6 is fixedly installed on the top of the frame 7, handrails 19 are fixedly connected to the front and rear sides of the top of the inner wall of the frame 7, and at least two pulleys 20 are installed on the left side of the first running board 1.

[0053] By providing handrails 19, users can easily place their hands, increasing stability and safety during running.

[0054] By setting up pulleys 20, the treadmill can be moved easily after it is erected, making it convenient for users to change the placement of the treadmill.

[0055] Furthermore, both the front and rear ends of the bottom of the first running board 1 and the second running board 2 are fixedly connected with support legs 3, and the number of support legs 3 is at least one.

[0056] By setting the support legs 3, the bottom of the first running board 1 and the second running board 2 can be easily supported, so that they can be placed stably on the ground. By setting the frame 7, the control panel 6 can be easily supported and fixed. By setting the control panel 6, the operating parameters of the treadmill can be easily adjusted.

[0057] Furthermore, as shown in Figure 3, a cleaning mechanism 4 is fixedly installed on the right side of the second running board 2, and the cleaning mechanism 4 cleans the impurities on the surface of the running belt 5.
