Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a sliding fitness device with built-in sliding components. 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 is recessed along its length to form a sliding groove. The sliding component is supported in the sliding groove by rollers provided on its bottom side and slides relative to the base by sliding along the sliding groove. Since the base is often formed by an upper shell and a lower shell, in actual use, the upper shell mainly supports the sliding component and the exerciser standing on the sliding component. However, the upper shell is far from the ground and is easily deformed by force, affecting the support effect, so its load-bearing capacity is poor. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing a sliding fitness device with a built-in sliding component. The lower shell component supports the sliding structure and the user on the sliding structure, resulting in stronger support and improved load-bearing capacity of the overall structure of the sliding fitness device, making it suitable for a wider range of people.

[0005] The technical solution adopted in this utility model is as follows: A sliding fitness device with a built-in sliding component includes a base structure and a sliding structure. The base structure includes a lower shell for placing on a medium surface and an upper shell connected to the upper side of the lower shell. The upper shell and the lower shell form a base cavity. The lower shell has a sliding track arranged in the base cavity along its length, and the upper shell has an active channel along its length. The sliding structure includes a sliding plate arranged on the upper side of the upper shell, a sliding member arranged in the base cavity and slidably supported on the sliding track, and a support assembly connecting the sliding plate and the sliding member. The support assembly includes a support member arranged in the active channel. The sliding structure slides relative to the base structure by sliding the sliding member along the length of the sliding track. When the sliding structure slides, the support member moves along the length of the active channel.

[0006] Preferably, the support assembly further includes a connecting frame arranged in the base cavity and connected to the support member. The sliding plate is connected to the upper end of the support member, the sliding member is connected to the lower end of the support member and / or the sliding member is connected to the connecting frame. When the sliding plate drives the support member to move upward relative to the movable channel, it can be limited by the connecting frame abutting against the upper shell member.

[0007] Preferably, the connecting frame includes a connecting body and multiple connecting seats connected to the connecting body via corresponding sliding rails. Multiple sliding members are provided and are respectively connected to each connecting seat.

[0008] Preferably, the sliding element 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.

[0009] Preferably, the support member has multiple corresponding connecting seats. 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. Each connecting seat and the lower end of the corresponding 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] Preferably, the lower shell has at least two parallel sliding tracks spaced apart, the upper shell has at least two parallel movable channels spaced apart, the support assembly includes at least two sliders slidably connected to the corresponding sliding tracks, and at least two support members arranged in the corresponding movable channels; the connecting body has at least two connecting seats on both sides arranged along the width direction of the base structure, each connecting seat is connected to the slider, and each support member in the movable channel is arranged corresponding to each connecting seat.

[0014] 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. The sliding structure is connected to each supporting base plate. The structure also includes a handrail frame, which is detachably connected to at least one supporting base plate; or... 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... 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.

[0015] The beneficial effects achieved by this utility model are as follows: The sliding fitness device provided by this utility model has a sliding component of its sliding structure built into the base cavity inside the base structure and slidably supported on a sliding track provided on the lower shell. The lower shell supports the sliding structure and the user on it. Compared to existing structures that rely on an upper shell for support, the lower shell is closer to the ground or other surfaces, resulting in a lower center of gravity, greater structural stability, and stronger support capacity. This improves the overall load-bearing capacity of the sliding fitness device and makes it suitable for a wider range of users. Furthermore, the upper shell has an active channel along its length. The sliding plate component of the sliding structure is connected to the sliding component via a support assembly. This support assembly supports the sliding plate component on the upper side of the upper shell, and includes a support member arranged within the active channel. The sliding structure moves along the sliding track via the sliding component. The sliding structure slides along the length of the track relative to the base structure. As the sliding structure slides, the support component moves along the length of the movable channel. This movable channel ensures that the sliding structure can move relative to the base structure along its length. Simultaneously, the upper shell conceals the sliding component and track within the base cavity of the base structure. Compared to existing designs that expose the sliding component and track to the top surface of the base structure, the upper shell prevents external debris from falling into the track and interfering with the sliding component's movement. For example, hair or other debris can become entangled on the sliding component, affecting its smooth sliding. The upper shell ensures smooth sliding of the structure relative to the base structure. Furthermore, the placement of the sliding track and component within the base cavity makes the external structure of the sliding fitness device simpler, more aesthetically pleasing, and more practical.

[0030] like Figures 1-7As shown in the figure, as an embodiment of the present invention, a sliding fitness device with a built-in sliding member 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. The lower shell 11 has a sliding track 111 arranged in the base cavity along its length direction, and the upper shell 12 has an active channel 121 along its length direction. The sliding structure 2 includes a sliding plate 21 arranged on the upper side of the upper shell 12, a sliding member 22 arranged in the base cavity and slidably supported on the sliding track 111, and a support assembly connecting the sliding plate 21 and the sliding member 22. The support assembly includes a support member 23 arranged in the active channel 121. The sliding structure 2 slides relative to the base structure 1 by sliding the sliding member 22 along the length direction of the sliding track 111. When the sliding structure 2 slides, the support member 23 moves along the length direction of the active channel 121. In this embodiment of the sliding fitness device, the sliding component 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 the structure in the prior art that provides 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, the upper shell 12 has an active channel 121 along its length. The sliding plate component 21 of the sliding structure 2 is connected to the sliding component 22 through a support assembly. The support assembly can support the sliding plate component 21 on the upper side of the upper shell 12, and the support assembly includes a support component 23 arranged in the active channel 121. The sliding structure 2 slides along the sliding track 111 provided by the sliding component 22. The sliding structure 2 slides along the length of the track 111 relative to the base structure 1. When the sliding structure 2 slides, the support member 23 moves along the length of the movable channel 121. The movable channel 121 ensures that the sliding structure 2 can move relative to the base structure 1 along the length of the base structure 1. At the same time, the upper shell 12 can also block and hide the sliding member 22 and the sliding track 111 in the base cavity inside the base structure 1. Compared with the existing structure that exposes the sliding member and the sliding track on the top surface of the base structure, the upper shell 12 can prevent some external debris from falling into the sliding track 111 and causing interference when the sliding member 22 slides. For example, hair and other debris may get tangled on the sliding member and affect its smooth sliding. The upper shell 12 ensures the smoothness of the sliding structure 2 relative to the base structure 1. In addition, the sliding track 111 and the sliding member 22 are located in the base cavity, which also makes the external structure of the sliding fitness device simpler, more beautiful and more practical.

[0031] like Figure 3As shown, in some specific embodiments, the support assembly further includes a connecting frame 24 arranged in the base cavity and connected to the support member 23. The sliding plate 21 is connected to the upper end of the support member 23, and the sliding member 22 is connected to the connecting frame 24. When the sliding plate 21 drives the support member 23 to move upward relative to the movable channel 121, it can be limited by the connecting frame 24 abutting against the upper shell member 12, thereby preventing the sliding structure 2 from disengaging from the base structure 1. In other embodiments, the sliding member 22 can also be configured to be connected to the lower end of the support member 23, or configured to be connected to both the lower end of the support member 23 and the connecting frame 24. In both cases, the sliding member 22 can be arranged in the base cavity and connected to the sliding plate 21 through the support assembly.

[0032] like Figure 5 As shown, 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.

[0033] like Figure 5 As shown, in some specific embodiments, the connecting frame 24 includes a connecting body 241 and a plurality of connecting seats 242 connected to the connecting body 241 and corresponding sliding rails 111. Multiple sliding members 22 are provided and are respectively connected to each connecting seat 242 to improve the stability of the sliding structure 2 sliding support on the sliding rails 111.

[0034] 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.

[0035] In some specific embodiments, the connecting seat 242 is provided with 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.

[0036] In some specific embodiments, the support member 23 is provided with multiple corresponding connecting seats 242. The support member 23 is recessed from its lower end upward to accommodate the upper end of the roller. The lower end of the support member 23 forms a first connecting part 232 and a second connecting part 233 on both sides of the recess 231 along the length direction of the base structure 1. Each connecting seat 242 and the lower end of the corresponding support member 23 are detachably connected by fasteners such as screws and bolts that are respectively engaged between the first connecting part 232 and the connecting seat 242, and between the second connecting part 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.

[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 7 As 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 base 122 and the fixed pulley 123 are mounted 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, thereby dispersing the force on the base structure 1. Of course, in other embodiments, the second mounting base 122 and / or the fixed pulley 123 can also be mounted on the lower shell 11, so that when the sliding structure 2 slides relative to the base structure 1, the lower shell 11 can simultaneously bear the weight of the sliding structure 2 and the exerciser on the sliding structure 2, as well as the tension applied by the elastic structure 3.

[0039] like Figure 5As 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 7 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 6 , Figure 7As shown, in some specific embodiments, the lower shell 11 has two parallel sliding rails 111 spaced apart, and the upper shell 12 has two parallel movable channels 121 spaced apart. The support assembly includes four rectangularly arranged sliding members 22 slidably connected to the corresponding sliding rails 111, and two support members 23 arranged in the corresponding movable channels 121. The connecting body 241 has two connecting seats 242 connected to both sides arranged along the width direction of the base structure 1. Each connecting seat 242 is connected to a sliding member 22. Each support member 23 in the movable channel 121 is arranged corresponding to each connecting seat 242. The overall structure is simple and stable. The support members 23 are connected to each other through connecting frames 24, which can... The stability of the support member 23 structure is enhanced by the connecting frame 24, and the movement of the sliding structure 2 along the width direction of the base structure 1 can be limited by the two movable channels 121 abutting against the side walls of the support member 23 inside. Simultaneously, the sliding track 111 is configured as a groove structure, with the lower end of the roller limited within the groove structure. The movement of the sliding structure 2 along the width direction of the base structure 1 can also be further limited by the sliding track 111 abutting against the side walls of the roller inside. The cross-section of the support member 23 is configured as a long strip structure arranged along the length direction of the movable channel 121, which increases the contact area between the movable channel 121 and the side walls of the support member 23, thereby ensuring the stable sliding of the sliding structure 2 along the length direction of the base structure 1. Of course, in other embodiments, the sliding track 111, movable channel 121, sliding member 22, support member 23, or connecting seat 242 can also be configured in other quantities.

[0042] like Figure 2 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.
