Description

Technical Field

[0001] This utility model relates to a fitness equipment, and more particularly to a multi-folding treadmill. Background Technology

[0002] As living standards continue to improve, people are paying more and more attention to physical exercise, and running is the simplest and most effective way to stay fit, making treadmills increasingly popular. For easier storage, some users choose foldable treadmills, which can be folded for storage to save space.

[0003] However, traditional folding treadmills typically only lift the running platform upwards for storage, resulting in limited space savings. Even existing folding treadmills with hinged front and rear running platforms only fold up to cover the front platform, further limiting space savings, and the front platform still occupies a significant area. Furthermore, existing folding treadmills generally cannot adjust the incline, failing to simulate uphill, flat, and downhill running, thus unable to meet diverse user needs. Therefore, this application proposes a multi-folding treadmill that offers a more compact folding design and incline adjustment, addressing the shortcomings of traditional folding treadmills in terms of storage compactness and incline adjustment. Utility Model Content

[0004] This utility model provides a multi-folding treadmill, which achieves a compact storage configuration while also allowing for adjustable running platform incline. The specific technical solution is as follows:

[0005] A multi-folding treadmill includes a foldable running platform, comprising a hinged front running platform and a rear running platform, and a running belt, the running belt being fitted onto the front and rear running platforms. The end of the front running platform away from the hinged rear running platform is hinged to a front support frame. A handrail assembly is provided above the front support frame, and a support leg assembly is provided below the front support frame. When folded, the rear running platform can be flipped up and covered the front running platform. The front running platform can drive the entire rear running platform to rotate relative to the front support frame to a vertical position to complete the folding and storage of the front and rear running platforms. The handrail assembly and the support leg assembly are linked and can be simultaneously bent inwards towards the front support frame to achieve the overall folding and storage of the treadmill.

[0006] Furthermore, the front support frame includes a fixed frame, a column assembly is vertically arranged above the fixed frame, a slide block is slidably arranged at one end of the column assembly near the fixed frame, the end of the front running platform is hinged to the slide block, and the lower part of the front end of the front running platform is connected to the slope adjustment component. The slope adjustment component can drive the slide block and the end of the front running platform to move up and down with the rear end of the rear running platform as the fulcrum, so as to achieve the effect of adjusting the slope.

[0007] Furthermore, the slope adjustment component includes a lifting support, lifting legs, and lifting linkage. One end of the lifting support is hinged to the front running platform, and the other end of the lifting support is slidably mounted on the fixed frame. One end of the lifting legs is hinged to the end of the front running platform near the rear running platform, and the other end of the lifting legs is in contact with the ground. Both ends of the lifting linkage are hinged to the lifting support and the lifting legs, respectively. The lifting support, the front running platform, the lifting legs, and the lifting linkage form a quadrilateral structure.

[0008] Furthermore, rollers are provided under both the lifting support frame and the lifting legs. The rollers of the lifting support frame can slide relative to the fixed frame, and the rollers of the lifting legs can slide relative to the ground.

[0009] Furthermore, the fixed frame is provided with a track for the rollers of the lifting support to slide. The track is fixedly installed on the inner side of the fixed frame. The track includes a top plate, a bottom plate, and a limiting plate. The top plate and the bottom plate together restrict the movement trajectory of the rollers of the lifting support to keep them horizontal, and the limiting plate can limit the movement distance of the rollers of the lifting support.

[0010] Furthermore, the top plate of the track is equipped with roller inlets and outlets. When the slope of the running platform is adjusted to be horizontal, the rollers of the lifting bracket correspond to the roller inlets and outlets. When the running platform is folded up, the rollers of the lifting bracket can be moved out from the roller inlets and outlets. When the running platform is unfolded from a vertical position, the rollers of the lifting bracket can enter the track from the roller inlets and outlets.

[0011] Furthermore, the handrail assembly is connected to the support leg assembly via a control assembly. The control assembly includes a first rotating shaft, a rotating shaft connecting rod, and a second rotating shaft connected to each other. The first rotating shaft is located at the top of the front support frame, and the second rotating shaft is located at the bottom of the front support frame. The support leg assembly is hinged to the bottom of the front support frame. The handrail assembly is connected to the first rotating shaft, and the support leg assembly is connected to the second rotating shaft. The handrail assembly can rotate relative to the column via the first rotating shaft and drive the second rotating shaft to rotate, thereby driving the support leg assembly to rotate synchronously.

[0012] Furthermore, a self-locking component is provided inside the handrail assembly, which can lock the handrail assembly in the unfolded state.

[0013] Furthermore, the self-locking component includes a self-locking cylinder and a pin. The self-locking cylinder is provided with a slot that mates with the pin. The self-locking cylinder is fixedly located at the top of the column. The pin is movably connected to the handrail assembly and is connected to an elastic component. The elastic component continuously provides the pin with a force to insert into the slot. The pin is connected to a lever, and the lever is slidably connected to the handrail assembly.

[0014] Furthermore, the self-locking assembly also includes a guide post, one end of which is fixedly connected to the pin and arranged parallel to the pin, and the other end of which is movably inserted into the first rotating shaft.

[0015] This utility model features a clever structural design, making it convenient to store and unfold.

[0031] To better understand the purpose, function, and specific design of this utility model, the multi-fold treadmill of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] like Figure 1-13 As shown, the multi-folding treadmill of this utility model includes a foldable running platform 2. The running platform 2 includes a front running platform 21 and a rear running platform 22 hinged together, and a running belt 23. A soft running board 24 is provided above the front running platform 21 and the rear running platform 22. The running belt 23 is fitted onto the front running platform 21 and the rear running platform 22. The end of the front running platform 21 away from the rear running platform 22 is hinged to the front support frame 1. A handrail assembly 3 is provided above the front support frame 1, and a support leg assembly 4 is provided below the front support frame 1. When folding, the rear running platform 22 can be flipped up and covered on the front running platform 21. The front running platform 21 can drive the rear running platform 22 to rotate relative to the front support frame 1 to a vertical state to complete the folding and storage of the front running platform 21 and the rear running platform 22. The handrail assembly 3 and the support leg assembly 4 are linked together. The handrail assembly 3 and the support leg assembly 4 can be bent inwards towards the front support frame 1 simultaneously to realize the overall storage and folding of the treadmill.

[0033] Specifically, the front support frame 1 includes a fixed frame 11, a column 12 is vertically arranged above the fixed frame 11, a slide block 13 is slidably arranged at one end of the column 12 near the fixed frame 11, the end of the front running platform 21 is hinged to the slide block 13, the lower part of the front end of the front running platform 21 is connected to the slope adjustment component 5, the slope adjustment component 5 can drive the slide block 13 and the end of the front running platform 21 to move up and down with the rear end of the rear running platform 22 as the fulcrum, thereby achieving the effect of adjusting the slope.

[0034] The slide 13 includes a slide bracket 131, on which multiple rollers are provided. The rollers abut against the column 12 and can roll vertically relative to the column 12. The end of the front running platform 21 is hinged to the slide bracket 131.

[0035] like Figure 2 and Figure 4 As shown, the incline adjustment component 5 includes a lifting support 51, a lifting leg 52, and a lifting linkage 53. One end of the lifting support 51 is hinged to the front running platform 21, and the other end of the lifting support 51 is slidably mounted on the fixed frame 11. One end of the lifting leg 52 is hinged to the end of the front running platform 21 near the rear running platform 22, and the other end of the lifting leg 52 is in contact with the ground. The two ends of the lifting linkage 53 are respectively hinged to the lifting support 51 and the lifting leg 52. The lifting support 51, the front running platform 21, the lifting leg 52, and the lifting linkage 53 form a quadrilateral structure so that the rotation of the lifting support 51 can drive the lifting leg 52 to rotate synchronously through the lifting linkage 53. That is, the lifting support 51 and the lifting leg 52 are linked. By changing the tilt angle of the lifting support 51 and the lifting leg 52, the incline of the treadmill as a whole is adjusted with the rear end of the rear running platform 22 as the fulcrum.

[0036] It is understandable that, since the lifting support 51 and the lifting leg 52 are linked, both the lifting support 51 and the lifting leg 52 can continuously provide support for the running platform 2 when adjusting the slope, thereby ensuring the stability of the running platform 2 during use. In addition, to improve the load-bearing capacity at the connection point between the front running platform 21 and the rear running platform 22 during use, a load-bearing component 23 is provided below the end of the front running platform 21 near the rear running platform 22. When the rear running platform 22 is unfolded to the horizontal, it can abut against the load-bearing component 23, which provides support for the rear running platform 22. In this embodiment, the load-bearing component 25 includes a load-bearing plate 251. One end of the load-bearing plate 251 is fixed below the end of the front running platform 21 near the rear running platform 22, and the other end of the load-bearing plate 251 extends away from the front running platform 21.

[0037] The lifting support 51 is connected to one end of the lifting drive assembly 54, and the other end of the lifting drive assembly 54 is connected to the front running platform 21. The lifting drive assembly 54 can drive the lifting support 51 to rotate relative to the front running platform 21 to achieve incline adjustment of the treadmill. In this embodiment, the lifting drive assembly 54 includes a lifting motor, which is fixed below the front running platform 21 and can swing relative to the front running platform 21. The lifting motor is connected to a telescopic push rod assembly 55, which is connected to the lifting support 51. The lifting motor drives the extension and retraction of the push rod assembly 55 to drive the lifting support 51 to rotate relative to the front running platform 21, thereby achieving stepless adjustment of the incline of the running platform 2.

[0038] Preferably, to improve the smoothness of slope adjustment of the running platform 2, rollers are provided under both the lifting bracket 51 and the lifting leg 52 in this embodiment. This allows the rollers of the lifting bracket 51 to slide relative to the fixed frame 11 and the rollers of the lifting leg 52 to slide relative to the ground when adjusting the slope of the running platform 2. It is worth noting that the fixed frame 11 in this embodiment is provided with a track 14 for the rollers of the lifting bracket 51 to slide. The track 14 is fixedly installed on the inner side of the fixed frame 11 and includes a top plate 141, a bottom plate 142, and a limiting plate 143. The top plate 141 and the bottom plate 142 together restrict the movement trajectory of the rollers of the lifting bracket 51 to remain horizontal, thereby ensuring stability when adjusting the slope of the running platform 2. The limiting plate 143 restricts the movement distance of the rollers of the lifting bracket 51, thereby limiting the maximum elevation angle of the running platform 2 and preventing over-adjustment that could damage the equipment.

[0039] It is worth noting that, such as Figure 6-7 As shown, a roller inlet / outlet 144 is provided on the top plate 141 of the track 14. When the slope of the running platform 2 is adjusted to be horizontal, the rollers of the lifting bracket 51 correspond to the roller inlet / outlet 144. When the running platform 2 is folded up, the rollers of the lifting bracket 51 can be moved out from the roller inlet / outlet 144 so that the running platform 2 can be folded in a vertical state. When the running platform 2 is unfolded from a vertical state, the rollers of the lifting bracket 51 can enter the track 14 from the roller inlet / outlet 144, so that the rollers of the lifting bracket 51 can move within the track 14 when the slope of the running platform 2 is adjusted.

[0040] like Figure 11-12 As shown, in order to facilitate the storage and folding of the running platform 2, a spring bracket 15 is provided on the fixing frame 11. The spring bracket 15 is connected to one end of the gas spring 16, and the other end of the gas spring 16 is connected to the rear end of the front running platform 21. When folding and storing the running platform 2, the gas spring 16 can provide assistance so that the user can easily fold and store the running platform 2.

[0041] like Figure 8-13 As shown, in this embodiment, the armrest assembly 3 is connected to the support leg assembly 4 through the control assembly 6. The armrest assembly 3 can drive the support leg assembly 4 to rotate synchronously, so as to realize that the armrest assembly 3 and the support leg assembly 4 can switch synchronously between the retracted state and the unfolded state.

[0042] Specifically, the control component 6 includes a first rotating shaft 61, a rotating shaft connecting rod 62, and a second rotating shaft 63 connected to each other. The first rotating shaft 61 is located at the top of the front support frame 1, i.e., at the top of the column 12. The second rotating shaft 63 is located at the bottom of the front support frame 1, i.e. on the fixed frame 11. The support leg assembly 4 is hinged to the bottom of the front support frame 1, i.e., hinged to the fixed frame 11. The handrail assembly 3 is connected to the first rotating shaft 61, and the support leg assembly 4 is connected to the second rotating shaft 63. The handrail assembly 3 can rotate relative to the column 12 through the first rotating shaft 61 and drive the second rotating shaft 63 to rotate, thereby driving the support leg assembly 4 to rotate synchronously.

[0043] Preferably, in order to improve the reliability of the handrail assembly 3 during use, the handrail assembly 3 in this embodiment is provided with a self-locking component 7. The self-locking component 7 can lock the handrail assembly 3 in the unfolded state to prevent the handrail assembly 3 from folding during user use and causing an accident.

[0044] The self-locking assembly 7 includes a self-locking cylinder 71 and a pin 72. The self-locking cylinder 71 is provided with a slot 711 that cooperates with the pin 72. The self-locking cylinder 71 is fixedly installed at the top of the column 12. The pin 72 is movably connected to the handrail assembly 3. When the handrail assembly 3 is in the unfolded state, the pin 72 can be inserted into the slot 711 of the self-locking cylinder 71 to prevent the handrail assembly 3 from rotating.

[0045] To facilitate locking or unlocking the armrest assembly 3, the latch 72 is connected to a spring-loaded component. The spring-loaded component continuously provides force for the latch 72 to insert into the slot 711 of the self-locking cylinder 71, thereby improving the reliability of the latch 72 during use. The latch 72 is connected to a lever 73, which is slidably connected to the armrest assembly 3. The lever 73 has a ridged actuating surface that conforms to the finger. By levering the lever 73, the user can overcome the force of the spring-loaded component and pull the latch 72 out of the slot 711 of the self-locking cylinder 71, thus unlocking the armrest assembly 3. At this time, the armrest assembly 3 can be switched from the unfolded state to the retracted state. Additionally, as... Figure 10 As shown, when the handrail assembly 3 switches from the retracted state to the unfolded state, under the action of the elastic component, the end of the pin 72 remains in contact with the arc surface of the self-locking cylinder 71 until the handrail assembly 3 rotates to the unfolded state. Under the action of the elastic component, the pin 72 automatically inserts into the slot 711 of the self-locking cylinder 71 to achieve the self-locking function.

[0046] Preferably, in order to improve the stability of the movement trajectory of the pin 72, the self-locking component 7 in this embodiment further includes a guide post 75. One end of the guide post 75 is fixedly connected to the pin 72 and is arranged parallel to the pin 72. The other end of the guide post 75 is movably inserted into the first rotating shaft 61. Since the movement path of the guide post 75 is determined, the stability of the pin 72 during the insertion and removal process can be guaranteed.

[0047] The self-locking assembly 7 in this embodiment also includes an L-shaped connecting plate 76. One end of the L-shaped connecting plate 76 is fixedly connected to the guide post 75, and the other end of the L-shaped connecting plate 76 is connected to the lever 73 and the pin 72. Alternatively, the elastic assembly can be a tension spring. One end of the tension spring is fixedly connected to the L-shaped connecting plate 76, and the other end is fixedly connected to the first rotating shaft 61 or the handrail assembly 3. It is understood that the elastic assembly can also be in other forms, as long as it can continuously provide the pin 72 with the force required to insert into the slot 711 of the self-locking cylinder 71.

[0048] like Figure 9 As shown, the support leg assembly 4 is hinged to the fixed frame 11 via a third pivot 41. The control assembly 6 also includes a drive link 64. Eccentric flanges are respectively provided on the second pivot 63 and the third pivot 41. One end of the drive link 64 is connected to the eccentric flange of the second pivot 63, and the other end of the drive link 64 is connected to the eccentric flange of the third pivot 41, so that the second pivot 63 and the third pivot 41 are linked. By setting the drive link 64, the position of the support leg assembly 4 can be set more flexibly to adapt to different models of treadmills. Preferably, in order to reduce the resistance when folding and unfolding the support leg assembly 4, a caster wheel is provided at the end of the support leg assembly 4 away from the hinged end with the fixed frame 11.

[0049] This utility model features a clever structural design, making it convenient to store and unfold. The front and rear running platforms can be folded up and then folded back into a vertical position. Furthermore, both the handrail and support leg components can be folded for storage, resulting in a highly compact storage configuration that significantly reduces the space occupied by the fitness equipment. In addition, the handrail and support leg components are linked, making storage and unfolding more convenient and faster. Finally, the slope adjustment component allows for stepless adjustment of the running platform's incline, greatly enhancing the user experience.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
