Description
Technical Field
[0001] This utility model relates to the field of fitness equipment, and in particular to a foldable exercise equipment with a self-supporting force shielding structure. Background Technology
[0002] As living standards continue to improve, people are paying more and more attention to physical exercise. Therefore, they use various types of exercise to achieve fitness goals. Among these, walking and running are the simplest and most effective fitness methods, making treadmills and walking machines increasingly popular. For easier storage, some exercisers choose foldable treadmills or walking machines, which can be folded for storage to save space.
[0003] Most existing foldable walking machines or treadmills fold by lifting the entire running platform upwards. Due to the large size and weight of the running platform, some users with less strength find it difficult to fold the treadmill. Therefore, the applicant has developed a walking machine and treadmill with a foldable running platform, which greatly reduces the force required for folding. However, after folding and storing, the folding area of the walking machine and treadmill is exposed to the external environment, and the folding part is mostly a mechanical structure such as a hinge mechanism, resulting in an unsightly and messy folding area. In addition, over time, dust will accumulate at the folding area, affecting the normal operation of the hinge mechanism and other mechanical structures, increasing the resistance during folding, affecting the lifespan of the equipment, and even causing damage. Therefore, it is necessary to design a shielding structure to solve the above problems. Utility Model Content
[0004] This utility model provides a foldable exercise equipment with a self-protecting structure, which can cover the exposed parts of the exercise equipment at the folding position, achieving a cleaner appearance and preventing dust from falling in. The specific technical solution is as follows:
[0005] A foldable exercise equipment with a self-power shielding structure includes a foldable first running platform and a second running platform. Running belts are installed on both the first and second running platforms. A retractable roller shutter is installed at the connection point between the first and second running platforms. One end of the roller shutter is fixed inside the first running platform, and the other end is fixed inside the second running platform. When the first and second running platforms are unfolded, the roller shutter retracts and is located below the running belts. When the first and second running platforms are folded, the roller shutter extends and wraps around the outside of the connection point between the first and second running platforms to shield the connection point.
[0006] Furthermore, one end of the roller shutter is fixed inside the first running platform, and the other end of the roller shutter is wound around the spring return mechanism, which can continuously provide winding force to the roller shutter. The spring return mechanism is fixed inside the second running platform.
[0007] Furthermore, the rebounder includes a fixed rod, which is connected to the rotating sleeve via an elastic member. When the rotating sleeve rotates relative to the fixed rod, the elastic member can provide a restoring force to the rotating sleeve.
[0008] Furthermore, a mounting base is provided below the end of the second running platform that is connected to the first running platform. The mounting base is provided with an L-shaped slot, in which the fixing rod can be placed. The mounting base and the mounting plate are detachably connected. The mounting plate can fix the fixing rod in the mounting base to achieve the connection of the rebound device.
[0009] Furthermore, a limiting post is provided between the end of the mounting base and the second running platform and the first running platform. The limiting post is located on the side of the roller shutter close to the running belt and abuts against the roller shutter. The limiting post can restrict the movement path of the roller shutter when it extends or retracts.
[0010] Furthermore, the limiting post is rotatably fixed on the limiting seat, which is located below the end of the mounting base connected to the second running platform and the first running platform. The limiting seat is provided with a rotating groove that cooperates with the limiting post, and the limiting post can be inserted into the rotating groove. The upper part of the limiting seat is detachably connected to the limiting plate, which can restrict the limiting post within the rotating groove.
[0011] Furthermore, the upper surface of the end connecting the second running platform and the first running platform is provided with an arc-shaped sliding surface. The side of the roller shutter away from the limiting post abuts against the sliding surface. The sliding surface can support the roller shutter, and the sliding surface and the limiting post cooperate to form a moving channel for the roller shutter to extend or retract. The moving channel formed by the sliding surface and the limiting post can prevent the roller shutter from shaking when it extends or retracts.
[0012] Furthermore, the height of the limiting post is lower than the height of the sliding surface.
[0013] Furthermore, a limiting mounting flange is provided at the end where the first running platform connects to the second running platform. An installation platform is provided on the side of the mounting flange away from the second running platform. A fixing plate is detachably connected to the installation platform. The end of the roller blind is wound around the fixing plate. Multiple through holes are provided on both the roller blind and the fixing plate. The roller blind and the fixing plate are fixed to the installation platform with screws. The roller blind extends out from the gap between the mounting flange and the fixing plate, thereby realizing the installation of the roller blind.
[0014] Furthermore, the height of the mounting flange is lower than the height of the upper surface of the end where the second runway connects to the first runway.
[0015] This utility model features an ingenious structural design. An automatically retractable roller blind covers the exposed portion of the folded area of the sports equipment, preventing dust, water, or other debris from falling in. This protects the safety of the folded area while also maintaining a neat and aesthetically pleasing appearance. The rebound mechanism and the roller blind's movement channel effectively prevent friction between the blind and the running belt, ensuring smoothness and stability during extension and retraction, significantly enhancing the user experience.
[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0025] To better understand the purpose, function, and specific design of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of the foldable exercise equipment with a self-supporting force shielding structure.
[0026] like Figure 1-7 As shown, the foldable exercise equipment with a self-supporting shielding structure of this utility model includes a foldable first running platform 1 and a second running platform 2. A running belt 3 is provided on the first running platform 1 and the second running platform 2. A retractable roller blind 4 is provided at the connection position between the first running platform 1 and the second running platform 2. One end of the roller blind 4 is fixed inside the first running platform 1, and the other end of the roller blind 4 is fixed inside the second running platform 2. When the first running platform 1 and the second running platform 2 are unfolded, the roller blind 4 is retracted and located below the running belt 3. When the first running platform 1 and the second running platform 2 are folded, the roller blind 4 extends out and wraps around the outside of the connection position between the first running platform 1 and the second running platform 2 to shield the connection position.
[0027] In one embodiment, the roller blind 4 is an elastic band. The roller blind 4 retracts due to its own elasticity. The roller blind 4 is positioned below the running belt 3 and spaced apart from the running belt 3 by a distance greater than 5 mm to avoid interference with the running running belt 3. However, since the elastic band is in a stretched state for a long time, it will be difficult to return to its original state. Therefore, if the elastic band is used as the roller blind 4, the elastic band may not be able to retract after the sports equipment has been stored for a long time, thus interfering with the running belt 3.
[0028] Therefore, in another preferred embodiment, one end of the roller blind 4 is fixed inside the first running platform 1, and the other end of the roller blind 4 is wound around the spring rebounder 5. The spring rebounder 5 can continuously provide winding force to the roller blind 4, and the spring rebounder 5 is fixed inside the second running platform 2. When the first running platform 1 and the second running platform 2 are unfolded, the roller blind 4 is retracted and both the roller blind 4 and the spring rebounder 5 are located below the running belt 3 with a distance greater than 5 mm between them. When the first running platform 1 and the second running platform 2 are folded, the roller blind 4 is released on the spring rebounder 5, and the roller blind 4 extends out and wraps around the outside of the connection position of the first running platform 1 and the second running platform 2 to cover the connection position.
[0029] Specifically, such as Figure 7As shown, the rebound device 5 includes a fixed rod 51, which is connected to a rotating sleeve 53 via an elastic member 52. When the rotating sleeve 53 rotates relative to the fixed rod 51, the elastic member 52 provides a restoring force to the rotating sleeve 53. In this embodiment, the fixed rod 51 includes a fixed end 511, a limiting end 512, and an insertion end 513. The limiting end 512 is disposed on both sides of the fixed end 511 and is perpendicular to the fixed end 511. The side of the limiting end 512 away from the fixed end 511 is connected to the insertion end 513. The insertion ends 513 connected to the two limiting ends 512 extend towards each other and are parallel to the fixed end 511. The insertion ends 513 are connected to one end of the elastic member 52, and the other end of the elastic member 52 is connected to the rotating sleeve 53. The two insertion ends 513 are respectively inserted into both sides of the rotating sleeve 53 to achieve the connection of the rotating sleeve 53. In this embodiment, the elastic component 52 is a tension spring. It can be understood that when there is one tension spring, the tension spring can be connected to any insertion end 513, and then connected to the end of the corresponding rotating sleeve 53 of this insertion end 513 to complete the assembly of the spring returner 5. When there are two tension springs, each insertion end 513 is connected to one tension spring, and then the two tension springs are respectively connected to the end of the corresponding rotating sleeve 53.
[0030] Preferably, in order to reduce the assembly difficulty of the spring rebounder 5, the spring rebounder 5 in this embodiment includes a tension spring, and a plug 54 is detachably connected to each end of the rotating sleeve 53. The two plugs 54 are provided with insertion holes for the insertion end 513 to be connected. One plug 54 is fixedly connected to one end of the tension spring, and the other end of the tension spring is fixedly connected to the corresponding insertion end 513. Then, the rotating sleeve 53 is connected to the plug 54 connected to the tension spring, and the other plug 54 is connected to the rotating sleeve 53 and the corresponding insertion end 513 is inserted into the plug 54 to complete the assembly of the spring rebounder 5.
[0031] like Figure 5-6 As shown, a mounting base 21 is provided below the end of the second running platform 2 that is connected to the first running platform 1. The mounting base 21 is provided with an L-shaped slot. The connection position between the fixing end 511 and the limiting end 512 of the fixing rod 51 can be placed in the L-shaped slot. The mounting base 21 and the mounting plate 22 are detachably connected. The mounting plate 22 can fix the fixing rod 51 in the mounting base 21 to realize the connection of the rebound device 5. By setting the L-shaped slot and the mounting plate 22, the fixing rod 51 can be limited in all directions, thereby preventing the roller shutter 4 from getting stuck due to the shaking of the rebound device 5 when it extends or retracts, thus ensuring the smoothness and stability of the roller shutter 4 when it extends or retracts.
[0032] like Figure 3-4As shown, a limiting post 6 is also provided between the end of the mounting base 21 connected to the second running platform 2 and the first running platform 1. The limiting post 6 is located on the side of the roller blind 4 near the running belt 3 and abuts against the roller blind 4. The limiting post 6 can restrict the movement path of the roller blind 4 when it extends or retracts, thereby preventing the roller blind 4 from rubbing against the running belt 3 and other structures when it extends or retracts. In this embodiment, the limiting post 6 is rotatably fixed on the limiting seat 23. The limiting seat 23 is located below the end of the mounting base 21 connected to the second running platform 2 and the first running platform 1. The limiting seat 23 is provided with a rotating groove that cooperates with the limiting post 6. The limiting post 6 can be inserted into the rotating groove. The upper part of the limiting seat 23 is detachably connected to the limiting plate 24. The limiting plate 24 can restrict the limiting post 6 in the rotating groove and prevent the limiting post 6 from coming out of the rotating groove, thereby improving the reliability of the limiting post 6 when it is working, and further ensuring the smoothness and stability of the roller blind 4 when it extends or retracts.
[0033] It is worth noting that, in this embodiment, the upper surface of the end where the second running platform 2 connects to the first running platform 1 is provided with an arc-shaped sliding surface 25. The side of the roller blind 4 away from the limiting post 6 abuts against the sliding surface 25. The sliding surface 25 can support the roller blind 4, and the sliding surface 25 and the limiting post 6 cooperate to form a moving channel for the roller blind 4 to extend or retract. The moving channel formed by the sliding surface 25 and the limiting post 6 can prevent the roller blind 4 from shaking when extending or retracting, thereby further ensuring the smoothness and stability of the roller blind 4 when extending or retracting. It can be understood that the sliding surface 25 can also reduce the friction between the roller blind 4 and the end of the second running platform 2, preventing damage to the roller blind 4. Preferably, the height of the limiting post 6 is lower than the height of the sliding surface 25 to form a negative angle moving channel, that is, a moving channel away from the running belt 3, thereby further preventing the roller blind 4 from rubbing against the running belt 3 and other structures, ensuring the smoothness and stability of the roller blind 4 when extending or retracting. In addition, after the second runway 2 is folded down with the first runway, the moving channel can also ensure that the roller shutter 4 will not leave a large gap with the end of the runway after it is extended, thus ensuring the effectiveness of the shielding.
[0034] A mounting flange 11 is provided at the end where the first running platform 1 connects to the second running platform 2. A mounting platform 12 is provided on the side of the mounting flange 11 away from the second running platform 2. A fixing plate 13 is detachably connected to the mounting platform 12. The end of the roller blind 4 is wound around the fixing plate 13. Multiple through holes are provided on both the roller blind 4 and the fixing plate 13. The roller blind 4 and the fixing plate 13 are fixed to the mounting platform 12 with screws. The roller blind 4 extends out through the gap between the mounting flange 11 and the fixing plate 13, thus achieving the installation of the roller blind 4. A triple fixation is formed by the screw fixing, the pressing between the fixing plate 13 and the mounting platform 12, and the clamping between the mounting flange 11 and the fixing plate 13, effectively improving the reliability of the connection between the roller blind 4 and the first running platform 1. Preferably, the height of the mounting flange 11 is lower than the height of the upper surface of the end where the second running platform 2 connects to the first running platform 1, that is, the height of the mounting flange 11 is lower than the height of the sliding surface 25. This avoids friction between the mounting flange 11 and the roller blind 4 under the support of the sliding surface 25, thereby improving the service life of the roller blind 4.
[0035] The roller blind 4 in this embodiment can be made of materials such as PEVA, PVC, polyester taffeta, and Oxford cloth. Among them, PEVA material is popular because of its good environmental performance, weather resistance and breathability. The material itself has the characteristics of sun protection, rain protection and dust protection, and can resist the erosion of the external environment for a long time without aging. It is very suitable for the use environment of this utility model.
[0036] This utility model features an ingenious structural design. An automatically retractable roller blind covers the exposed portion of the folded area of the sports equipment, preventing dust, water, or other debris from falling in. This protects the safety of the folded area while also maintaining a neat and aesthetically pleasing appearance. The rebound mechanism and the roller blind's movement channel effectively prevent friction between the blind and the running belt, ensuring smoothness and stability during extension and retraction, significantly enhancing the user experience.
[0037] 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.
