Description

[Technical Field]

[0001] The present invention relates to the field of treadmill technology, and more particularly to folding treadmills. [Background technology]

[0002] Treadmills are a very popular type of indoor aerobic fitness equipment that can simulate natural walking or running conditions, making them suitable for use in any weather or location. They are popular with fitness enthusiasts and are widely used in homes and other places.

[0003] The core structure of the mainstream home treadmills currently on the market typically includes a long running board that supports the user while running or walking, a stand located at the front end of the running board, and a support frame at the bottom. To accommodate the limited living space in a home environment, many products have a storage function, and a common method is to lift the entire running board upward around a hinge axis at the front end to convert it from a horizontal usage state to a nearly vertical storage state.

[0004] However, such conventional upright folding methods have significant drawbacks. When the vertical space is excessively occupied, even if the treadmill board is lifted vertically, its length is almost entirely converted into height after folding, so the overall height of the equipment when stored is still very large. This poses a clear vertical space obstacle in small houses, rooms with low storage space, or rooms with limited ceiling height, causing serious "waste of vertical space." The equipment is only placed against the wall, which not only spoils the aesthetics but also easily becomes a hindrance in daily life.

[0005] Furthermore, the overall shape of a vertically folded treadmill is long and narrow, with a high center of gravity and a large volume, making it difficult to move and to find a suitable storage location. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention addresses the shortcomings of the prior art by providing a folding treadmill that reduces the longitudinal folding of the running machine by folding the running frame and running boards, thereby reducing storage space and making it easier to use. [Means for solving the problem]

[0007] To solve the above technical problems, the present invention is solved by the following technical solution. The folding treadmill of the present invention comprises a front running frame on which a front running board is provided, a rear running frame foldably connected to the front running frame and on which a rear running board is provided, and compensation pads provided on the upper surfaces of the front running board and / or the rear running board, the compensation pads being used to compensate for or overcome steps or resistance formed when the front running board and the rear running board are stepped on at their connection points after being unfolded.

[0008] In the above technical solution, preferably, the compensation pad is provided on the surface of one end of the front running board close to the rear running board and extends toward the other end, and the upper surface of the compensation pad is higher than the surface of the rear running board after the front running board and the rear running board are deployed.

[0009] In the above technical solution, preferably, the compensation pad is provided on the surface of one end of the rear running board close to the front running board and extends toward the other end, and the upper surface of the compensation pad is higher than the surface of the front running board after the front running board and the rear running board are deployed.

[0010] In the above technical solution, preferably, a buffer pad is provided between the ends of the front running board and the rear running board that abut each other after the front running board and the rear running board are deployed, and the buffer pad is provided on the front running board or the rear running board.

[0011] The above technical solution preferably includes at least one rotating part arranged between the front running frame and the rear running frame, and the rotating part changes the relative angle between the front running frame and the rear running frame to realize relative folding and unfolding between the running frames.

[0012] In the above technical solution, preferably, the rotating part includes a first positioning member and a second positioning member provided on the front running frame and the rear running frame, respectively, and the first positioning member and the second positioning member are rotatably connected via a rotation axis.

[0013] In the above technical solution, preferably, the axis of the rotation shaft is on the same plane as or higher than the end faces of the front running frame and the rear running frame in the unfolded state, and the rotation shaft is located on the side where the angle between the front running frame and the rear running frame becomes smaller when they are folded against each other via the rotating part.

[0014] In the above technical solution, preferably, a locking part is provided between the front running frame and the rear running frame to fix the two relative to each other after deployment, and the locking part includes a first locking member provided on the front running frame and a second locking member provided on the rear running frame, and after the rear running frame is deployed relative to the front running frame, the locking is achieved by engagement between the second locking member and the first locking member.

[0015] In the above technical solution, preferably, the first locking member is provided with a locking hole, a transition groove is provided on the side of the locking hole facing the rear running frame, elastic walls are provided on both sides of the locking hole, and the transition groove is elastically deformed when the transition groove expands to both sides, and the second locking member is provided with a locking core fitted into the locking hole.

[0016] In the above technical solution, preferably, the locking part includes a base mounted on the front running frame, the first locking member is swingably mounted on the base, and a transition groove is formed at one end of the elastic walls on both sides of the locking hole that is close to the rear running frame, and the first locking member is elastically hinged to one end that is remote from the rear running frame via a pin shaft, and the pin shaft is rotatably connected to the base. [Effects of the Invention]

[0017] The beneficial effect of this invention is that the novel bi-fold structural design of this invention significantly improves the space utilization rate and user experience of the treadmill.

[0018] Specifically, this design converts the height occupancy of a conventional treadmill when folded into a stack in the thickness direction, and by folding the front and rear running frames in half around a high-position rotation axis, it completely solves the problem of wasted vertical space caused by the conventional upright folding method. At the same time, the compensation pads installed on the front or rear running boards not only eliminate the height difference between the running boards and achieve tolerance compensation, but also reduce the resistance when the running belt passes through the connection point between the front and rear running boards. In addition, the buffer pads installed at the connection point between the front and rear running boards seal the gap to prevent foreign objects from entering, effectively reducing abnormal driving noise and improving the continuity of the feeling underfoot.

[0019] The design of the locking hole on the elastic wall and the locking core utilizes the elastic wall's deformation recovery mechanism to achieve a self-adaptive lock, allowing the lock to withstand high-intensity impacts without breaking, ensuring safe use. This design fundamentally solves the problem of space constraints while maintaining the full functionality of the treadmill, and also achieves multiple technical benefits, such as optimized connections and stronger locks, greatly improving the functionality and efficient use of the product.

[0021] The present invention will be described in more detail below with reference to the drawings and specific embodiments. 1 to 8, the folding treadmill includes a front running frame 1 and a rear running frame 2, which are independent frames. A front running board 101 is fixed to the upper end surface of the front running frame 1, and a rear running board 201 is fixed to the upper end surface of the rear running frame 2. The front running frame 1 and the rear running frame 2 are rotatably connected via a rotating part 3. Specifically, two sets of rotating parts 3 are provided, which are symmetrically provided on both sides of the running frame as shown in FIG. 3. The front running frame 1 or the rear running frame 2 has a support tube 8 below the connection point of the front running board 101 and the rear running board 201 after they are unfolded, for simultaneously supporting the above-mentioned running boards.

[0022] The top of the front running frame 1 is fixed to the front running board 101 by bolts, and its front end is attached to a front roller 102 by a bearing stand. The front roller 102 is a driven roller and is connected to a drive motor in a rotatable manner. The top of the rear running frame 2 is fixed to the rear running board 201 by bolts, and its rear end is attached to a rear roller 202 by a bearing stand. A running belt 7 is wound between the front roller 102 and the rear roller 202, and the running belt 7 completely covers the upper surfaces of the front running board 101 and the rear running board 201.

[0023] The rotating part 3 is firmly connected by a first positioning member 301 welded or bolted to one end of the front running frame 1 close to the rear running frame 2 at the tail end of the front running frame 1, a second positioning member 302 welded or bolted to one end of the rear running frame 2 close to the front running frame 1 at the head end of the rear running frame 2, and a rotating shaft 303 that horizontally passes through the axial holes of the first positioning member 301 and the second positioning member 302 to form a rotating pair, thereby realizing a rotational connection of the first positioning member 301 to the second positioning member 302.

[0024] The first positioning member 301 and the second positioning member 302 may be made of plate material and arranged alternately, and the rotating shaft 303 is drilled into the axial holes of the plate material one by one. After drilling, the rotating shaft 303 is put into a rotational engagement state.

[0025] The axis of the rotation shaft 303 is flush with or higher than the upper end surfaces of the front running board of the front running frame 1 and the rear running board of the rear running frame 2, and after the rear running frame 2 is folded upward relative to the front running frame 1 in the direction shown in Figure 3, it will be in the state shown in Figure 4, and there will be no interference when the front running board 101 and the rear running board 201 are folded back at the connecting end.

[0026] The rotation axis 303 is located on the side where the angle between the front running frame 1 and the rear running frame 2 becomes smaller when the front running frame 1 and the rear running frame 2 are folded together via the rotation part 3, and is located above the front running frame 1 and the rear running frame 2, as shown in Figure 3 as an example.

[0027] A compensation pad 4 is provided on the upper surface of the front running board 101 and / or rear running board 201. Specifically, the compensation pad 4 is provided on the upper surface close to the running belt. That is, the compensation pad 4 may be provided individually on the front running board 101 or the rear running board 201, or may be installed simultaneously on the front running board 101 and the rear running board 201. In this embodiment, as shown in FIG. 7, the compensation pad 4 is provided on the rear running board 201.

[0028] The compensation pad 4 is a flexible pad, the underside of which is fixedly connected to the front running board 101 or the rear running board 201 by adhesive, and the upper surface of which is smooth. When the compensation pad 4 is installed on the upper surface of the rear running board 201, one end of the compensation pad 4 is flush with the end surface of the rear running board 201 that is closest to the front running board 101, and the other end extends rearward toward the end that is farther away from the front running board 101. The length of the compensation pad 4 can extend to part or all of the surface of the rear running board 201, and the height of the surface of the compensation pad 4 is higher than the surface of the front running board 101. The height difference can be set to 0.2 to 1.5 mm, and in this embodiment, it is preferably 0.5 to 1 mm.

[0029] The compensation pad 4 may be installed on the upper surface of the front running board 101. When installed on the front running board 101, one end of the compensation pad 4 is flush with the end surface of the front running board 101 that is closest to the rear running board 201, and the other end extends forward toward the end that is away from the rear running board 201. Its length may extend to part or all of the surface of the front running board 101, and the height of the surface of the compensation pad 4 is higher than the surface of the rear running board 201, and the height difference may be set to 0.2 to 1.5 mm.

[0030] The compensation pad 4 compensates for or overcomes the step or resistance created when the front running board 101 and the rear running board 201 are stepped on at the connection points after being deployed.

[0031] After the front running board 101 and the rear running board 201 are deployed, a buffer pad 401 is provided between the ends that abut against each other, and the buffer pad 401 is provided on the front running board 101 or the rear running board 201. In this embodiment, the buffer pad 401 is provided on the front running board 101 as an example, and the cross section of the buffer pad 401 is a rectangular cross section, and the rectangular surface on one side of the buffer pad 401 is in close contact with the end face of the front running board 101 that is close to the rear running board 201, thereby compensating for the gap that occurs when the front running board 101 and the rear running board 201 are deployed, and the rectangular surface on the other side is extended and fixed toward the end face that is away from the running belt 7. When the buffer pad 401 is installed on the rear running board 201, its installation direction is symmetrical to when it is installed on the front running board 101, that is, the right-angled surface on one side is in close contact with the end surface of the rear running board 201, and the right-angled surface on the other side extends toward the lower end surface of the rear running board 201.

[0032] The upper end surface of the buffer pad 401 provided at the joint between the front running board 101 and the rear running board 201 may be lower than the front running board 101 or the rear running board 201, or may be flush with the end surface of the running board, thereby enabling a seamless connection between the front running board and the rear running board. The buffer pad 401 may also be a flexible pad, and may be made of a material having a certain degree of flexibility and elasticity, such as EVA single-sided adhesive.

[0033] A locking portion 5 is provided between the front running frame 1 and the rear running frame 2 to secure the two relative to each other after deployment. The locking portion 5 includes a base 6, a first locking member 501, and a second locking member 502. The base 6 is fixed to the side of one end of the front running frame 1 that is close to the rear running frame 2 by a bolt, and as shown in Figure 4, the base 5 is located below the front running board 101.

[0034] The first locking member 501 is hingedly connected to the base 6 via a pin shaft 601, and can swing around the pin shaft 601 at a certain angle to match the angle when the second locking member 502 is engaged. The second locking member 502 is welded or bolted to the side surface of one end of the rear running frame 2 that is close to the front running frame 1, and has a lock core 506 attached to its front end. The lock core 506 is cylindrical in shape and has an engagement opening that is smaller than the outer diameter of the lock core 506 at the connection point with the second locking member 502.

[0035] The first locking member 501 is provided with a locking hole 503 that fits a locking core 506, and elastic walls 505 made of spring steel are provided on both sides of the locking hole 503. The locking hole 503 is also cylindrical, and one end remote from the base 6 is provided with a transition groove 504 that passes through the locking hole 503. The locking core 506 presses the elastic walls 505 on both sides and then passes through the transition groove 504 into the locking hole 503. Then, the elastic walls 505 return and their ends are caught in the engagement openings, thereby forming an engagement between the first locking member 501 and the second locking member 502.

[0036] The end of the elastic wall 505 is elastically hinged to the base 6 via a pin shaft 601, and by incorporating a torsion spring therein, the elastic return function of the elastic wall 505 can be further improved.

[0037] A second running board is provided on each end face of the front running frame 1 and the rear running frame 2 away from the front running board 101 and the rear running board 201, and the second running board is a massage board with a plurality of protrusions on its surface. When the treadmill is unfolded, the second running board on the front running frame 1 and the second running board on the rear running frame 2 come into contact in the center, i.e., are in the same state as the front running board 101 and the rear running board 201 when the treadmill is unfolded. The running belt 7 is arranged to cover the front running board 101, rear running board 201 and second running board. That is, when the front running frame 1 and the rear running frame 2 are in an unfolded state, if the front of the front running board 101 and the rear running board 201 are facing upward, the treadmill is in a running state. When the front of the second running board is facing upward, that is, when the treadmill is in an unfolded state, the entire treadmill is turned over so that the front running board 101 and the rear running board 201 face the ground. At this time, the treadmill is in a massaging state, and the protrusions on the second running board provide a massaging effect to the feet.

[0038] Lock / Unlock Process: Locking: When the rear running frame 2 is deployed to a horizontal position, the locking core 506 slides along the transition groove 504, presses the elastic wall 505, and expands and deforms outward. After the locking core 506 fully enters the locking hole 503, the elastic wall 505 rebounds and engages with the engagement hole to achieve mechanical interlocking. Unlocking: Manually lift the rear running frame 2 upward relative to the front running frame 1, then fold it back using the rotating part 3, and forcibly pull the lock lower 506 out of the lock hole 503. The elastic wall 505 expands again, and finally the lock core 506 passes through the transition groove 504 and comes out of the lock hole 503, realizing the separation of the first locking member 501 and the second locking member 502, and completing the unlocking process.

[0039] The above embodiments are merely for illustrating the technical solutions of the present invention, and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, it should be understood that those skilled in the art may still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features thereof, and such modifications or substitutions shall not deviate from the essence of the corresponding technical solutions and the spirit and scope of the technical solutions of the embodiments of the present invention.
