Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a stable sliding fitness device. Background Technology

[0002] In recent years, people have paid more and more attention to fitness activities. Skiing fitness devices such as ski machines and skiing ab machines are fun and effective exercises that can help fitness enthusiasts exercise their legs, waist, abdomen and other body parts, enhance their coordination, balance and muscle strength, meet people's skiing fitness needs and are loved by fitness enthusiasts.

[0003] Existing gliding fitness devices, such as a silent ski machine with announcement number CN221692712U, include a base and a sliding component slidably connected to the upper side of the base. The top surface of the base has a limiting groove along its length, and the bottom side of the sliding component has a limiting block that is fastened to the lower side of the limiting groove. The upward movement of the sliding component relative to the base is limited by the limiting block abutting against the inner wall of the upper shell of the base. The width movement of the sliding component relative to the base is limited by the limiting groove abutting against the side wall of the limiting block. Since the entire sliding component is limited by only one limiting groove and the limiting block fastened to the limiting groove, the stability of the connection between the sliding component and the base is poor. The sliding component is prone to twisting relative to the base, which affects the safety of the user during the gliding exercise. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a stable sliding fitness device that enhances the stability of the connection between the sliding structure and the base structure, thereby improving the safety of users during sliding exercises and demonstrating strong practicality.

[0009] Preferably, the connecting frame and the support are detachably connected, the support and the slide plate are integrally formed, and the width of the movable channel is set to be greater than the cross-sectional width of the support, so as to allow the support to extend into the base cavity through the movable channel.

[0010] Preferably, the system further includes an elastic structure connecting the base structure and the sliding structure. The connecting frame also includes a first mounting seat connected to the lower side of the connecting body. The inner wall of the upper shell is provided with a second mounting seat arranged in the base cavity and a fixed pulley arranged along the length direction of the base structure on the side of the connecting body away from the second mounting seat. The elastic structure is wound around the fixed pulley, and one end is positioned connected to the first mounting seat and the other end is positioned connected to the second mounting seat.

[0011] Preferably, a groove is formed on the lower side of the connecting body between the first mounting base and the connecting base, and an opening is recessed at one end of the connecting body away from the second mounting base. The elastic structure is located in the groove, and the groove can move relative to the elastic structure when the sliding structure slides. When the sliding structure slides close to the fixed pulley, the fixed pulley can be accommodated in the opening.

[0012] Preferably, the inner wall of the upper shell is provided with a first abutment seat arranged in the base cavity and a second abutment seat arranged along the length direction of the base structure on the side of the connecting body away from the first abutment seat. The connecting body is provided with a first abutment part and a second abutment part on both sides arranged along the length direction of the base structure. The sliding stroke of the sliding structure along the length direction of the base structure is limited by the first abutment part abutting against the first abutment seat and the second abutment part abutting against the second abutment seat.

[0013] Preferably, the lower shell is provided with at least two sliding tracks arranged in parallel along its length direction within the base cavity. The sliding structure also includes sliding members that are respectively connected to each connecting seat and slidably supported on the corresponding sliding track. The sliding structure slides relative to the base structure by sliding the sliding members along the length direction of the sliding track.

[0014] Preferably, the sliding member is configured as a roller, and the connecting seat has a rolling groove corresponding to the roller. The roller is arranged in the rolling groove and is rotatably connected to the connecting seat through a connecting shaft arranged along the width direction of the base structure. The support member has a recessed portion from its lower end upward for accommodating the upper end of the roller. The lower end of the support member forms a first connecting portion and a second connecting portion on both sides of the recessed portion along the length direction of the base structure. The connecting seat and the lower end of the support member are detachably connected by fasteners that respectively cooperate to connect the first connecting portion and the connecting seat, and fasteners that cooperate to connect the second connecting portion and the connecting seat.

[0015] Preferably, the base structure includes two side-by-side supporting base plates, which are foldably connected by a hinge. Each supporting base plate includes a lower shell and an upper shell.

[0016] The base structure includes two parallel supporting base plates, each comprising the lower shell and an upper shell, and two sliding structures connected to the two supporting base plates respectively; or...

[0017] The base structure includes two supporting base plates arranged side by side. The two supporting base plates respectively include the lower shell and the upper shell. One side of the two sliding structures is connected to one of the supporting base plates, and the other side is connected to the other supporting base plate.

[0018] The beneficial effects achieved by this utility model are as follows:

[0019] The sliding fitness device provided by this utility model has at least two parallel movable channels spaced along its length on its upper shell. The connecting frame of the sliding structure and the sliding plate are connected by at least two support members arranged in the corresponding movable channels, spaced along the width of the base structure. This allows the connecting frame to abut against the upper shell to limit the sliding structure from detaching from the base structure when the sliding plate moves upward relative to the movable channels. When the sliding structure slides along the length of the base structure, the movement of the sliding plate in the width direction of the base structure can be achieved through the movable channels and its internal support members. The side walls of the components abut against each other for limiting, and the setting of multiple movement channels and support components, compared with the single limiting structure setting in the existing technology, can limit the sliding structure from more positions, thereby enhancing the stability of the connection between the sliding structure and the base structure, and reducing the risk of the sliding structure twisting relative to the base structure during the user's sliding exercise, thus improving the safety of the user during the sliding exercise. In addition, the connecting frame is connected to the skateboard component through multiple support components, which greatly improves the stability of the connection between the connecting frame and the skateboard component. At the same time, the connecting frame can also strengthen the stability of each support component structure by connecting them, making it highly practical.

[0034] like Figures 1-6As shown in the figure, as an embodiment of the present invention, a stable sliding fitness device is provided, including a base structure 1 and a sliding structure 2. The base structure 1 includes a lower shell 11 for placement on a surface such as the ground, and an upper shell 12 connected to the upper side of the lower shell 11. The upper shell 12 and the lower shell 11 surround each other to form a base cavity. Two parallel movable channels 121 are provided on the upper shell 12, spaced apart along its length. The sliding structure 2 is slidably connected to the base structure 1 along its length, and includes a sliding plate 21 arranged on the upper side of the upper shell 12, a connecting frame 24 arranged in the base cavity, and a support member 23 connecting the sliding plate 21 and the connecting frame 24. The support member 23 is arranged in two rows at intervals along the width direction of the base structure 1, corresponding to the movable channels 121, and is respectively arranged in the corresponding movable channels 121. In this embodiment of the sliding fitness device, the upper shell 12 has two parallel movable channels 121 spaced apart along its length. The connecting frame 24 of the sliding structure 2 and the sliding plate 21 are connected by two support members 23 spaced apart along the width of the base structure 1 and respectively arranged in the corresponding movable channels 121. This allows the connecting frame 24 to abut against the upper shell 12 to limit the movement of the sliding structure 2 relative to the base structure 1 when the sliding plate 21 moves upward relative to the movable channels 121, preventing the sliding structure 2 from disengaging from the base structure 1. When the sliding structure 2 slides along the length of the base structure 1, the movement of the sliding plate 21 in the width of the base structure 1 can be achieved through the movable channels 121 and its internal support members. The side walls of the support members 23 abut against each other for limiting. The arrangement of multiple movable channels 121 and support members 21, compared to the single limiting structure in the prior art, allows for limiting the sliding structure 2 from more positions, thereby enhancing the stability of the connection between the sliding structure 2 and the base structure 1. This reduces the risk of the sliding structure 2 twisting relative to the base structure 1 during the user's sliding exercise, improving safety. Furthermore, the connecting frame 24 is connected to the skateboard component 21 through multiple support members 23, greatly improving the stability of the connection between the connecting frame 24 and the skateboard component 21. Simultaneously, the connecting frame 24 strengthens the stability of each support member 23 structure by connecting them, making it highly practical. Of course, in other embodiments, the movable channels 121 can also be three, four, or more, and the support members 23 can be arranged in three, four, or more columns.

[0035] like Figure 6As shown, in some specific embodiments, the connecting frame 24 includes a connecting body 241 and connecting seats 242 respectively connected to both sides of the connecting body 241 along the width direction of the base structure 1. Each connecting seat 242 is arranged correspondingly to each support member 23, and each connecting seat 242 is connected to the lower end of the corresponding support member 23. In this embodiment, two connecting seats 242 are provided on both sides of the connecting body 241 along the width direction of the base structure 1 along the length direction of the base structure 1. Two support members 23 corresponding to the connecting seats 242 are provided in each movable channel 121. That is, each row of support members 23 is provided with two support members 23. The four support members 23 are arranged in a rectangle. The cross-section of the support member 23 is set as a long strip structure arranged along the length direction of the movable channel 121, which can increase the contact area between the movable channel 121 and the side wall of the support member 23, thereby further reducing the risk of the sliding structure 2 twisting relative to the base structure 1 during the user's sliding exercise. At the same time, it can ensure that the sliding structure 2 slides stably along the length direction of the base structure 1, improving the safety of the user during the sliding exercise. In other embodiments, three or more connecting seats may be provided on both sides of the connecting body 241, and three or more supporting members 23 may be provided in each active channel 121 to further enhance the stability of the connection between the sliding structure 2 and the base structure 1.

[0036] In some specific embodiments, the connecting frame 24 and the support member 23 are detachably connected. The width of the movable channel 121 is set to be greater than the cross-sectional width of the support member 23, so as to allow the support member 23 to extend into the base cavity through the movable channel 121, facilitating the assembly or disassembly of the support member 23 relative to the movable channel 121. The support member 23 and the slide plate member 21 are integrally formed, with a simple structure and a stable connection, facilitating the quick assembly or disassembly of the sliding structure 2 relative to the base structure 1. In other embodiments, the support member 23 can also be set as an independent structure and connected to the slide plate member 21 to facilitate processing and demolding, or the support member 23 can be integrally formed with the connecting frame 24.

[0037] In some specific embodiments, an elastic structure 3 is also included, connecting the base structure 1 and the sliding structure 2. The elastic structure 3 provides elastic resistance when the exerciser applies force to slide the sliding structure 2 relative to the base structure 1, thereby enhancing strength training. In this embodiment, the elastic structure 3 is set as an elastic rope. In other embodiments, the elastic structure 3 can also be set as an elastic band, tension spring, or other structures that can provide elastic resistance.

[0038] like Figure 3As shown, in some specific embodiments, the connecting frame 24 further includes a first mounting seat 243 connected to the lower side of the connecting body 241. The inner wall of the upper shell 12 is provided with a second mounting seat 122 arranged in the base cavity and a fixed pulley 123 arranged along the length direction of the base structure 1 on the side of the connecting body 241 away from the second mounting seat 122. The elastic structure 3 is wound around the fixed pulley 123, and one end is positioned connected to the first mounting seat 243, and the other end is positioned connected to the second mounting seat 122. In this embodiment, the second mounting seat 122 and the fixed pulley 123 are arranged on the upper shell 12, so that the upper shell 12 can bear the tension applied by the elastic structure 3 when the sliding structure 2 slides relative to the base structure 1. Of course, in other embodiments, the second mounting seat 122 and / or the fixed pulley 123 can also be arranged on the lower shell 11, so that the lower shell 11 can bear the tension applied by the elastic structure 3 when the sliding structure 2 slides relative to the base structure 1.

[0039] like Figure 6 As shown, in some specific embodiments, a groove 2411 is formed on the lower side of the connecting body 241, which is arranged between the first mounting base 243 and the connecting base 242. An opening 2412 is recessed at one end of the connecting body 241 away from the second mounting base 122. The elastic structure 3 is located in the groove 2411. When the sliding structure 3 slides, the groove 2411 can move relative to the elastic structure 3. When the sliding structure 3 slides close to the fixed pulley 123, the fixed pulley 123 can be accommodated in the opening 2412. The arrangement of the groove 2411 and the opening 2412 makes the connecting frame 24, the elastic structure 3, the lower shell 11 and the upper shell 12 structurally compact, and saves the production cost of the connecting frame 24.

[0040] like Figure 3 As shown, in some specific embodiments, the inner wall of the upper shell 12 is provided with a first abutment 124 arranged in the base cavity and a second abutment 125 arranged along the length direction of the base structure on the side of the connecting body 241 away from the first abutment 124. The connecting body 241 is provided with a first abutment portion 2413 and a second abutment portion 2414 on both sides arranged along the length direction of the base structure, respectively. The sliding stroke of the sliding structure 2 along the length direction of the base structure 1 is limited by the first abutment portion 2413 abutting against the first abutment 124 and the second abutment portion 2414 abutting against the second abutment 125.

[0041] like Figure 2 , Figure 4As shown, in some specific embodiments, the lower shell 11 is provided with two parallel sliding tracks 111 arranged in the base cavity along its length direction. The sliding structure 2 also includes sliding members 22 that are respectively connected to each connecting seat 242 and slidably supported on the corresponding sliding track 111. The sliding structure 2 slides relative to the base structure 1 by sliding the sliding members 22 along the length direction of the sliding track 111. In this embodiment, the sliding member 22 of the sliding structure 2 is built into the base cavity inside the base structure 1 and is slidably supported on the sliding track 111 provided on the lower shell 11. The lower shell 11 can support the sliding structure 2 and the exerciser on the sliding structure 2. Compared with some existing structures that provide support through the upper shell, the lower shell 11 is closer to the ground or other medium surface, so the center of gravity of the lower shell 11 is lower, the structure is more stable, and the support capacity is stronger, thereby improving the load-bearing capacity of the overall structure of the sliding fitness device and making it suitable for a wider range of people. In addition, when the sliding structure 2 slides, the support member 23 moves along the length of the movable channel 121, thereby ensuring that the sliding structure 2 can slide along the bottom. The seat structure 1 can move relative to the base structure 1 along its length. Simultaneously, the upper shell 12 can conceal the slider 22 and sliding track 111 within the base cavity of the base structure 1. Compared to some existing structures that expose the slider and sliding track on the top surface of the base structure, the upper shell 12 prevents external debris from falling into the sliding track 111 and causing interference when the slider 22 slides. For example, hair or other debris can become entangled on the slider, affecting its smooth movement. Thus, the upper shell 12 ensures the smoothness of the sliding structure 2 relative to the base structure 1. Furthermore, the placement of the sliding track 111 and slider 22 within the base cavity makes the external structure of the sliding fitness device simpler, more aesthetically pleasing, and more practical. Of course, in other embodiments, only one or more sliding tracks 111 may be provided, and the slider 22 may be arranged in one or more columns corresponding to the sliding tracks 111.

[0042] In some specific embodiments, the slider 22 is configured as a roller, which can slide relative to the sliding track 111 by rolling along the sliding track 111, thereby reducing the friction between the slider 22 and the sliding track 111 and making it easier for the slider 22 to slide along the sliding track 111. In other embodiments, the slider 22 can also be configured as a slider structure, which can also slide relative to the sliding track 111.

[0043] like Figure 5As shown, in some specific embodiments, the connecting seat 242 has a rolling groove 2421 corresponding to the roller. The roller is arranged in the rolling groove 2421 and is rotatably connected to the connecting seat 242 via a connecting shaft 2422 arranged along the width direction of the base structure 1. The setting of the rolling groove 2421 makes the roller and the connecting seat 242 structurally compact, thereby reducing the overall height of the base structure 1.

[0044] like Figure 6 As shown, in some specific embodiments, the support member 23 has a recessed portion 231 for accommodating the upper end of the roller from its lower end upward. The lower end of the support member 23 forms a first connecting portion 232 and a second connecting portion 233 on both sides of the recessed portion 231 along the length direction of the base structure 1. Each connecting seat 242 is detachably connected to the lower end of the corresponding support member 23 by fasteners such as screws and bolts that are respectively connected between the first connecting portion 232 and the connecting seat 242, and fasteners such as screws and bolts that are connected between the second connecting portion 233 and the connecting seat 242. The structure is stable, the connecting frame 24 is not easy to fall off, and the roller, connecting seat 242 and support member 23 are arranged in a compact manner, thereby further reducing the overall height of the base structure 1.

[0045] like Figure 1 , Figure 3 As shown, in some specific embodiments, the base structure 1 includes two supporting base plates 101 arranged side by side. The two supporting base plates 101 are foldably connected by a hinge 102 for easy folding and storage. The two supporting base plates 101 each include a lower shell 11 and an upper shell 12. The sliding structure 2 is connected to the two supporting base plates 101 respectively. The exerciser can stand on the two sliding structures 2 and apply force so that the two sliding structures 2 slide relative to the two supporting base plates 101, thereby performing skiing exercises.

[0046] In some specific embodiments, a handrail frame 4 is also included. The handrail frame 4 is detachably connected to the two support base plates 101 through a plug-in structure and fasteners such as screws and bolts, which makes it convenient for fitness users to selectively assemble or disassemble the handrail frame 4 according to their fitness needs. In other embodiments, the handrail frame 4 may also be detachably connected to only one of the support base plates 101, or it may be detachably connected to the support base plate 101 through other connection structures such as snap-fit ​​structures. All of these can achieve a detachable connection between the handrail frame 4 and the base structure 1.

[0047] In another embodiment of this utility model, the base structure 1 may also include two supporting base plates arranged in parallel. The two supporting base plates respectively include the lower shell 11 and the upper shell 12. The sliding structure 2 is connected to the two supporting base plates respectively. The exerciser can support his / her body parts such as his / her hands or elbows on the two sliding structures 2 and apply force. The two sliding structures 2 slide relative to the two supporting base plates respectively, thereby performing abdominal exercises.

[0048] As another embodiment of this utility model, the base structure 1 may also include two supporting base plates arranged in parallel. The two supporting base plates respectively include the lower shell 11 and the upper shell 12. One side of the two sliding structures 2 is connected to one of the supporting base plates and the other side is connected to the other supporting base plate. The exerciser can stand on the two sliding structures 2 and apply force to the two sliding structures 2 to slide relative to the two supporting base plates at the same time, thereby performing skiing exercises.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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 scope of the technical solutions of the embodiments of this utility model.

[0050] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
