Description

Technical Field

[0001] This utility model relates to the field of therapeutic rehabilitation exercise technology, and in particular to a leg-swinging fitness machine for multiple scenarios. Background Technology

[0002] Knee osteoarthritis (KOA), also known as proliferative knee arthritis or senile knee arthritis (commonly referred to as "old cold legs"), is a common chronic joint disease characterized by functional and morphological degeneration. The earliest and most significant pathological changes occur in the cartilage, followed by subchondral bone cysts, osteophyte formation at the joint margins, and ultimately, complete destruction and deformity of the normal articular surface, leading to increased pain and limited range of motion.

[0003] The "Chinese Clinical Practice Guidelines for Osteoarthritis Pain Management (Chinese Journal of Orthopaedics 2020 Edition)" lists exercise therapy as a 1A (strong recommendation, highest level) option for treating KOA, recommending leg-swinging exercises. Leg-swinging is believed to effectively treat knee pain and aid in rapid recovery. However, the exact mechanism by which leg-swinging effectively treats knee pain has remained unclear for a long time. In the patent document authorized by publication number "CN113952677B" and entitled "Treatment and Rehabilitation Equipment for Knee Osteoarthritis Based on KOAPT Therapy," inventor Mr. Song Jiuhong first discovered that leg-swinging exercises can drive non-contact movement of the upper and lower joint surfaces of the knee joint and contraction and relaxation movements of the synovial bursa around the knee joint cavity through hip joint swinging; this secondarily causes the intra-articular pressure to increase and decrease in stages and alternately; thereby promoting the secretion and absorption of synovial fluid in the joint cavity; thus effectively removing various inflammatory factors and pain factors from the joint cavity; and because of the increased circulation of synovial fluid, it promotes a positive repair trend of articular cartilage; overall, it alleviates the symptoms of knee pain and provides a valuable pathophysiological basis for the repair of damaged articular cartilage. Furthermore, the patent document defines the modern standard KOAPT leg-swinging therapy (Knee Osteoarthritis Pendulum) for the first time based on this scientific discovery. KOAPT (Therapy) has launched a pendulum-style leg-swinging rehabilitation training device. Notably, its patent literature introduces the scientific concept of "correct-comfort ratio" (a suitable proportion between correct and comfortable). Achieving this "correct-comfort ratio" requires support components to support the user's limbs and reduce weight during leg swings, thereby reducing the load on the single weight-bearing leg and achieving standardized, comfortable, and sustainable leg-swinging exercise. By combining the training device with KOAPT therapy, it can induce a phased, alternating increase and decrease in intra-articular pressure, thereby promoting intra-articular lubrication. The secretion and absorption of synovial fluid effectively removes various inflammatory and pain-causing factors from the joint cavity. Furthermore, the increased circulation of synovial fluid promotes positive repair of articular cartilage, generally alleviating knee pain symptoms and providing a valuable pathophysiological basis for the repair of damaged articular cartilage. Simultaneously, it efficiently strengthens the flexor and extensor muscles of the leg and significantly improves the sensitivity of lower limb proprioceptors. However, existing leg-swinging rehabilitation devices are complex in structure, costly, space-consuming, and inconvenient for widespread use by the general public. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a leg-swinging fitness machine that is easy to use, has a simple structure, adapts to various visual scenarios and multiple functions, occupies little space, and allows a wide range of users to perform leg-swinging therapy in various scenarios.

[0005] To achieve the above objectives, the leg-swinging fitness machine designed in this application is characterized by including a base plate, a single upright bracket, and a support plate. The support plate is disposed above the base plate. One end of the single upright bracket is fixedly connected to the base plate, and the other end is fixedly connected to the bottom of the support plate. The upper surface of the base plate is provided with a standing area, and the upper surface of the support plate is provided with an upper limb support area. The upper limb support area and the standing area are disposed on the same side relative to the single upright bracket.

[0006] By adopting the above technical solution, compared with the existing technology which sets support frames or semi-enclosed support structures on both sides of the leg swinging standing area, this device uses a single upright support to play a supporting role. The single upright support can be located on one side or in the middle of the base plate, outside the leg swinging path. Furthermore, the single upright support can be a single upright support formed by a single column, or it can be an integral single upright support formed by multiple columns spaced apart side by side. The advantages of this design are that the base plate, single-standing bracket, and support plate form a "C" shape, freeing up lateral space between the base plate and support plate, saving space, and making the device suitable for use in various scenarios such as home, hospital, office, and long-distance high-speed rail, making it more suitable for a wider range of people. Furthermore, the "C" shape provides high mechanical stability. When the user's upper limbs are supported in the upper limb support area and their legs are standing in the standing area while performing leg-swinging movements, the "C" shape formed by the support plate, single-standing bracket, and base plate effectively ensures the overall stability of the device during leg-swinging. Moreover, the standing area and upper limb support area of ​​this device are defined by specific positions of the base plate and support plate, not actual tangible components, making the device structure simple and ingenious. Users immediately recognize the "C" shape formed by the support plate, single-standing bracket, and base plate for leg-swinging and know that their legs are standing on the base plate and their arms are supporting themselves on the upper limb support area, making the device simpler and more convenient to operate.

[0007] Furthermore, one end of the single-standing support is connected to the middle of the base plate, the standing area of ​​the base plate is configured to be located on both sides of the single-standing support, and the upper limb support area of ​​the support plate is configured to be located on both sides of the single-standing support. The upper limb support area and the standing area are correspondingly set on the same side of the single-standing support.

[0008] By adopting the above technical solution, the device forms a double "C" shape structure around the single upright support located in the middle of the base plate, both front-to-back and left-to-right, further freeing up space in the front-to-back and left-to-right directions, making this application more space-saving. Moreover, the double "C" structure has higher stress stability, and the arrangement of the upper limb support area on both sides of the single upright support can effectively expand the stress area of ​​the support plate and disperse the stress points of the support plate, making the local pressure on the support plate smaller and further improving the support stability. On the other hand, the special design of the single upright support located in the middle of the standing area makes the single upright support act as a separator between the left and right standing legs, avoiding the user's leg swing path, so that the device can not affect the user's leg swing training, but also achieve stable support and weight reduction during leg swing. Furthermore, as soon as the user sees the single upright support located in the middle of the base plate, he immediately knows to use the single upright support in the middle as a reference point to stand with both legs on both sides of the single upright support, and put both arms on the upper limb support areas on both sides to swing his legs, making the operation of the device simpler and more convenient.

[0009] Furthermore, one end of the single-standing support is connected to the base plate located on the left or right side of the standing area. The standing area of ​​the base plate and the upper limb support area of ​​the support plate are both configured to be located on one side of the single-standing support, and the upper limb support area and the standing area are set on the same side relative to the single-standing support.

[0010] By adopting the above technical solution, the structure of the single vertical bracket located on the side of the base plate makes the base plate, the single vertical bracket, and the support plate form a large "C" shape structure. The lateral space between the base plate and the support plate is released to the maximum extent, saving space. In addition, when in use, the single vertical bracket can be placed against the wall to maximize the space-saving advantage of the device. The device has high support stability and is convenient for transportation and manufacturing.

[0011] Furthermore, the support plate includes a U-shaped opening, with upper limb support areas located on both sides of the U-shaped opening. First, the U-shaped opening serves as a guide and positioner for the device. Since it accommodates the user's torso, the user immediately recognizes that their torso is within the opening, they are standing in the standing area of ​​the base plate, and their arms are supported by the upper limb support areas on either side of the opening, simplifying the leg-swinging motion. Second, the U-shaped opening positions the relative roles of the standing and upper limb support areas. With the upper limb support areas on either side of the opening and the standing area below, the relative positions of these areas are fixed by the U-shaped opening. This positioning ensures the user maintains a vertical stance and correct arm support posture throughout the leg-swinging process, improving standardization and therapeutic efficacy. Furthermore, it maintains the user's posture during leg switching, providing stable support and increasing efficiency and stability during leg switching, thus enhancing the consistency and effectiveness of the training.

[0012] Furthermore, the base plate is equipped with leg partitions, with the standing area located on both sides of the leg partitions. The height of the leg partitions is such that the user can stand on either side of the partition, from their crotch to their feet, allowing for various leg positions. The leg partitions further enhance the separation of the left and right legs; they also guide the user's leg swings along the partitions during casual leg swings; they guide and correct the user's leg swings in the correct direction of walking; they prevent users from swinging their legs laterally, diagonally, or arbitrarily, and further reduce the probability of kicking the central single-standing support during leg swings, making the leg swing exercise smooth, effortless, worry-free, sustainable, injury-free, and unobstructed.

[0013] Furthermore, the base plate is equipped with leg partitions, with the standing area located on both sides of the leg partitions, which are positioned below the U-shaped opening. By adopting this technical solution, when the user stands inside the U-shaped opening, the leg partitions below the opening pre-separate the user's left and right legs. During leg-swinging exercises, the user swings their legs directly along the pre-set leg partitions, guiding them along the correct leg-swinging path. This avoids lateral, diagonal, or random, non-standard leg swings, improving the standardization of leg swinging and reducing the probability of kicking the single-standing support during the swing. This makes the leg-swinging exercise smooth, effortless, worry-free, sustainable, injury-free, and unobstructed.

[0014] Furthermore, the leg partition is fixedly connected to the single-standing support. By adopting the above technical solution, the leg partition is fixed to the single-standing support, resulting in a more compact and simple structure. The leg partition also improves the support stability of the single-standing support. In particular, the method of fixing the leg partition and the single-standing support into an integrated structure is superior. One side of the leg partition is fixedly connected to the single-standing support, and the other side is fixedly connected to the base plate. This not only improves the connection stability between the single-standing support and the leg partition but also simplifies the installation and operation of the device.

[0015] Furthermore, the single-standing support includes a telescopic adjustment device that allows for vertical telescopic adjustment, with the working end of the telescopic adjustment device fixedly connected to the bottom of the support plate. Through the telescopic adjustment device on the single-standing support, the support plate can be moved up and down in the vertical direction, allowing for adaptive adjustments to suit the correct posture of users of different heights, thus improving the flexibility of the device and standardizing leg-swinging fitness exercises.

[0016] Furthermore, the telescopic adjustment device includes a lower support body and a sliding column. The bottom of the lower support body is connected to the base plate, and the top of the lower support body is provided with a telescopic groove. One end of the sliding column is fixedly connected to the bottom of the support plate, and the other end of the sliding column is slidably inserted into the telescopic groove. The sliding column and the lower support body are fixed by a positioning pin. This technical solution realizes the specific implementation structure of the telescopic adjustment device. This method has a simple structure; adjusting the vertical extension and retraction of the sliding column moves the support plate, making the adjustment operation convenient, and the device structure has strong stability.

[0017] Furthermore, the sliding column has multiple first height positioning holes spaced at intervals along its extension direction, and the lower support body has second height positioning holes that match the first height positioning holes. Positioning pins pass through the first and second height positioning holes to fix the sliding column to the lower support body. This method is convenient for adjustment, simple in structure, and easy to manufacture.

[0018] Furthermore, the relative positions of the projections of the standing area and the upper limb support area onto the base plate in the vertical direction remain fixed. Since this application corresponds to active leg-swinging training, users typically tend to move their upper limbs when switching legs, causing changes in their body posture. The base plate, single-standing bracket, and support plate of this device are fixed structures, and the structure of the device does not change during leg switching. More specifically, the relative position of the projection of the upper limb support area onto the base plate in the vertical direction remains fixed. During leg switching, the upper limb support area can provide stable and positional support for the limbs, ensuring that the user's upper body does not change with the leg-swinging movement, effectively maintaining standardized posture and thus improving the effectiveness of leg-swinging training.

[0019] Furthermore, a flip-up tabletop is provided on the support plate. The flip-up tabletop includes a tabletop body and a flip plate. The tabletop body is installed on the other side of the support plate, and the flip plate is rotatably connected to the tabletop body, providing a first working position that is in contact with the tabletop body and a second working position that covers the U-shaped opening. When the flip plate is in the second working position, the leg-swinging exercise machine can be converted into a desktop mode. Items can be placed on the upper surface of the flip-up tabletop, or it can be used as a small table, achieving functional switching and transforming it into a piece of furniture with a novel and unique appearance.

[0020] Furthermore, multiple transverse load-bearing beams protrude from one side of the support plate to enhance the mechanical strength of the tabletop and ensure its stability when supporting the user's upper limbs or objects.

[0021] Furthermore, two elbow-extended load-bearing beams protrude from one side of the support plate, symmetrically positioned on either side of the U-shaped opening. These beams are perpendicularly inserted through multiple transverse load-bearing beams. The transverse load-bearing beams provide mechanical reinforcement to the underside of the support plate; simultaneously, the two elbow-extended load-bearing beams and the two transverse load-bearing beams are arranged perpendicularly and staggered to form a load-bearing network, further enhancing the overall load-bearing stability of the training frame.

[0022] Furthermore, the lower support includes two side support plates and multiple edge sealing plates. The two side support plates are arranged in parallel and spaced apart, and the multiple edge sealing plates are arranged between the two side support plates and spaced apart on both sides of the two side support plates in the horizontal direction along a direction perpendicular to the base plate, so as to form an expansion groove between the two side support plates.

[0023] Furthermore, reinforcing corner blocks are provided on the side plates that are furthest apart from each other, and these reinforcing corner blocks are connected to the base plate. This further improves the overall stability of the device.

[0024] Furthermore, a foot pedal box is provided on the base plate, which is located in the standing area and on one side of the single-standing bracket.

[0025] Furthermore, the base plate is equipped with guide rails, with both ends of the guide rails located on both sides of the single vertical bracket, and the foot pedal box is slidably mounted on the guide rails.

[0026] Furthermore, the bottom of the single-standing bracket is equipped with adjustment holes that match the foot pedal box, and the guide rail passes through the adjustment holes.

[0027] Furthermore, the bottom surface of the support plate is hinged to the top of the single-standing bracket. The hinge can be a hinge, bolt, or other type of hinge with a base, allowing the support plate to be folded and stored when not in use, further saving space.

[0028] Furthermore, the bottom surface of the support plate is detachably connected to the single-standing bracket via a snap-fit ​​or threaded connection. The support plate can be removed from the single-standing bracket for storage using either a snap-fit ​​or threaded connection. Snap-fit ​​and threaded connections are more stable than hinged connections.

[0029] This utility model proposes a leg-swinging fitness machine. A base plate provides a standing space for the user, and a single-leg support frame located in the center of the base plate connects to and supports the upper support plate. The user can stand on one leg on the base plate, supporting themselves with their forearm or arm on the support plate to maintain a stable posture, and then swing their affected leg for rehabilitation training with their own effort or the help of other auxiliary equipment. By placing the single-leg support frame in the center of the base plate, the space around the support plate and the base plate is completely open and unobstructed. This optimized placement of the single-leg support frame reduces interference with other objects during transport and placement. Furthermore, when not in use, other objects can be placed around the single-leg support frame, reducing its impact on indoor space. This effectively solves the technical problems of large space requirements, difficulty in transporting and setting up leg-swinging rehabilitation equipment in related technologies. It provides users with a user experience where "it's there whether you use it or not; whether you see it or not, it's always there. It doesn't feel like it takes up space; it only brings convenience and aesthetic pleasure." The leg-swinging fitness machine features a flip-up table that can be converted into a desktop mode. The top surface of the flip-up table can be used to place items or as a small table, allowing for functional switching. At the same time, its novel design adds a beautiful touch to interior furniture and décor. Thus, KOAPT exercise becomes readily available anytime, anywhere, making it an efficient and vibrant part of daily life. Attached Figure Description

Detailed Implementation

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1

[0042] like Figure 1 As shown, the leg-swinging fitness machine designed in this utility model includes a base plate 1, a single-standing support 2, and a support plate 3. The support plate 3 is disposed above the base plate 1 to provide support for the hands or arms of the standing user, ensuring stable standing training. The base plate 1 is rectangular. One end of the single-standing support 2 is fixedly connected to the middle of the upper surface of the base plate 1. The base plates 1 located on both sides of the single-standing support 2 are configured as standing areas 4. The other end of the single-standing support 2 is fixedly connected to the bottom of the support plate 3. The upper surfaces of the support plates 3 located on both sides of the single-standing support 2 are configured as upper limb support areas 5, which are correspondingly arranged on the same side as the standing areas 4.

[0043] The leg-swinging fitness machine provided in this embodiment of the invention provides a corresponding standing space for the user through the base plate 1, and connects and supports the upper support plate 3 through a single upright bracket 2 set in the middle of the base plate 1. The user can stand on one leg on the base plate 1 and maintain a stable standing posture by supporting themselves with their forearm or arm on the support plate 3, and swing their affected leg for rehabilitation training with their own strength or the help of other auxiliary equipment. This invention forms a double "C" shape structure around the single upright bracket 2 located in the middle of the base plate 1 in the front, back, left and right directions, which releases the lateral space between the base plate 1 and the support plate 3. When moving and placing the leg-swinging fitness machine, it can reduce interference with other objects, making the device easy to use in various scenarios such as home, hospital, office, and long-distance high-speed rail; and the double "C" shape structure has high mechanical stability. Furthermore, this utility model is a device specifically designed for users to exercise by swinging their legs. As soon as users see the single upright support 2 and the double "C" structure on the left and right, they will immediately know to use the single upright support 2 in the middle as a reference point, stand with both legs on both sides of the single upright support 2, and support their arms on the upper limb support areas 5 on both sides to perform the leg swinging exercise, making the operation of the device simpler and more convenient.

[0044] Furthermore, the support plate 3 includes a U-shaped opening 311, with upper limb support areas 5 located on both sides of the U-shaped opening 311. The U-shaped opening 311 can position the relative positions of the standing area 4 and the upper limb support areas 5. The upper limb support areas 5 are located on both sides of the U-shaped opening 311, and the standing area 4 is positioned below the U-shaped opening 311. The relative positions of the upper limb support areas 5 and the standing area 4 can be fixed by the U-shaped opening 311. Therefore, the U-shaped opening 311 positions the relative positions between the standing area 4 and the upper limb support areas 5, ensuring that the user maintains a correct leg-swinging posture with upright standing and arms supporting the body on both sides during leg swinging, improving the standardization of leg-swinging training and enhancing the therapeutic effect of leg-swinging therapy. It also ensures that the user's posture remains unchanged when switching legs, providing stable support during leg switching, improving the efficiency and stability of leg switching, and enhancing the consistency and effectiveness of leg-swinging training.

[0045] Furthermore, during the use of the device of this application, including when the user changes legs, the relative positions of the projections of the standing area 4 and the upper limb support area 5 onto the base plate 1 in the vertical direction remain fixed. Since this application corresponds to active leg-swinging training, users typically tend to move their upper limbs when changing legs, thus changing the user's body posture. The base plate 1, single-standing bracket 2, and support plate 3 of this device are fixed structures, and the structure of the device does not change when changing legs. More specifically, the relative position of the projection of the upper limb support area 5 onto the base plate 1 in the vertical direction remains fixed. When changing legs, the upper limb support area 5 can provide stable and positioning support for the limbs, ensuring that the user's upper body does not change with the leg-changing movement, effectively maintaining a standardized posture, thereby improving the effect of leg-swinging training.

[0046] Furthermore, the bottom surface of the support plate 3 is detachably connected to the single-standing bracket 2 via a snap-fit ​​or threaded connection. The support plate 3 can be removed from the single-standing bracket and stored using either a snap-fit ​​or threaded connection. Snap-fit ​​and threaded connections are more stable than hinged connections.

[0047] Example 2

[0048] See Figure 2 This utility model provides a leg-swinging fitness machine. The difference from Embodiment 1 is that one end of the single-standing support 2 is connected to the base plate 1 on the left or right side of the standing area 4. Both the standing area 4 of the base plate 1 and the upper limb support area 5 of the support plate 3 are configured to be located on one side of the single-standing support 2. The upper limb support area 5 and the standing area 4 are arranged on the same side relative to the single-standing support 2. In this embodiment, the single-standing support 2 is located on the side where the user stands in the standing area 4 to perform leg-swinging exercises. This C-shaped structure maximizes the volume freed up by the lateral space, saving space. Furthermore, when in use, placing the single-standing support 2 against a wall maximizes the space-saving advantage of the device.

[0049] Furthermore, such as Figure 3 As shown, the bottom surface of the support plate 3 is hinged to the top of the single vertical bracket 2. The hinge can be a hinge, bolt, or base, allowing the support plate 3 to be folded and stored when not in use, further saving space.

[0050] Example 3

[0051] As a preferred embodiment of this utility model, such as Figure 4 and Figure 5A rotating tabletop 32 is provided on the support plate 3. The rotating tabletop 32 includes a tabletop body 321 and a rotating plate 322. The tabletop body 321 is mounted on the other side of the support plate 3. The rotating plate 322 is rotatably connected to the tabletop body 321, so as to have a first working position that is in contact with the tabletop body 321 and a second working position that covers the U-shaped opening 311. Exemplarily, in this embodiment, a rotating tabletop 32 composed of a tabletop body 321 and a rotating plate 322 that are hinged to each other is provided on the support plate 3. When the user needs to perform leg-swinging training, the rotating plate 322 can be flipped up, and the second working position can be flipped to the first working position, so that the U-shaped opening 311 is exposed, and the user can stand in front of the U-shaped opening 311 to perform leg-swinging training. In another operating condition, by flipping the rotating plate 322 back to the second working position, the U-shaped opening 311 is covered and blocked by the rotating plate 322. The rotating plate 322 can then be flush with the tabletop body 321 to form a rotating tabletop 32 with a complete flat surface. At this time, the leg-swinging exercise machine can be converted into a desktop mode. The upper surface of the rotating tabletop 32 can be used to place items or as a small table, realizing the function switching and improving the practicality of the leg-swinging exercise machine.

[0052] In another preferred embodiment, a plurality of transverse load-bearing beams 312 are protruding from one side of the support plate 3. Exemplarily, in this embodiment, two transverse load-bearing beams 312 are spaced apart on the bottom surface of the support plate 3 used to connect with the single vertical bracket 2. These beams primarily enhance the mechanical strength below the tabletop 321, ensuring the stability of the tabletop 321 when supporting a user's arm or objects. Further, two elbow-extending load-bearing beams 313 are protruding from one side of the support plate 3. These beams are symmetrically arranged on both sides of the U-shaped opening 311, and vertically pass through the plurality of transverse load-bearing beams 312. The elbow-extending load-bearing beams 313 span the tabletop 321 and are located below the flip plate 322 in the second working position, primarily reinforcing the mechanical strength of the support plate 3 below the U-shaped opening 311. Meanwhile, the two elbow-extended load-bearing beams 313 and the two transverse load-bearing beams 312 are arranged perpendicularly to form a load-bearing network, further improving the overall load-bearing stability.

[0053] As another preferred implementation, such as Figure 6The single-standing support 2 includes a telescopic adjustment device for vertical telescopic adjustment. The working end of the telescopic adjustment device is fixedly connected to the bottom of the support plate 3. The telescopic adjustment device includes a lower support body 21 and a sliding column 22. The bottom of the lower support body 21 is connected to the base plate 1, and the top of the lower support body 21 is provided with a telescopic groove 211. One end of the sliding column 22 is perpendicularly connected to one side surface of the support plate 3, and the other end of the sliding column 22 is slidably inserted into the telescopic groove 211. Multiple first height positioning holes 221 are arranged at intervals along the extension direction on the sliding column 22. The lower support body 21 is provided with second height positioning holes 212 that match the first height positioning holes 221. Positioning pins pass through the first height positioning holes 221 and the second height positioning holes 212 to fix the sliding column 22 to the lower support body 21. This method is convenient for adjustment, simple in structure, and easy to process and produce. For example, in this embodiment, by adjusting the insertion depth of the sliding column 22 in the telescopic groove 211, the sliding column 22 can be extended or retracted vertically relative to the lower support body 21, thereby adjusting the height of the support plate 3 from the ground. This accommodates users of different heights and further improves the overall adaptability of the leg-swinging fitness machine. Simultaneously, by aligning the first height positioning hole 221 on the sliding column 22 with the second height positioning hole 212 on the lower support body 21, the extension height can be confirmed, and it can be limited and fixed by positioning pins or insertion bolts. The structure is simple and easy to install.

[0054] Optionally, the lower support body 21 includes two side support plates 213 and multiple edge sealing plates 214. The two side support plates 213 are arranged in parallel and spaced apart, and the multiple edge sealing plates 214 are disposed between the two side support plates 213 and are spaced apart along the horizontal side edges of the two side support plates 213 in a direction perpendicular to the base plate 1, so as to form a telescopic groove 211 between the two side support plates 213. Exemplarily, the lower support body 21 uses two spaced side support plates 213 to form a flattened support body, and multiple edge sealing plates 214 are provided on both sides of the slit formed by the two side support plates 213 for connection and support, and a telescopic groove 211 structure is defined inside. While ensuring the telescopic cooperation and guidance with the sliding column 22, the lower support body 21 is modularized and lightweight, further improving its practicality.

[0055] Optionally, a reinforcing corner block 215 is provided on the side surface of the two side support plates 213 that is far apart from each other, and the reinforcing corner block 215 is connected to the base plate 1. Exemplarily, in this embodiment, by providing a reinforcing corner block 215 structure on the side surface of the two side support plates 213 that is far apart from each other, the reinforcing corner block 215 can act as a reinforcing rib to enhance the connection stability between the base plate 1 and the side support plate 213, further improving the overall structural stability of the leg swing fitness machine.

[0056] Example 4

[0057] In this embodiment, see Figure 7 A foot pedal box 11 is provided on the base plate 1, located within the standing area 4 and on one side of the single-standing support 2. The foot pedal box 11 can be designed as a training device with automatic counting function specifically for leg swinging, or it can be a common block structure with a certain mechanical strength (or other shapes that provide support). When the user needs to perform leg swinging training, they can step on the foot pedal box 11 located on one side of the single-standing support 2, i.e., within the standing area 4, while their arms can be supported by their forearms or forearms on the support plate 3, ensuring that the user can maintain a stable, vertical standing posture. At this time, the other affected leg is suspended in the air, and the user can swing the affected leg for rehabilitation training with their own strength or the help of other assistive devices.

[0058] In this embodiment, see Figure 8 The base plate 1 is provided with a guide rail 12, with both ends of the guide rail 12 located on both sides of the single-standing bracket 2. The foot pedal box 11 is slidably mounted on the guide rail 12. Exemplarily, in this embodiment, the purpose of providing the foot pedal box 11 is to ensure that the affected leg on the other side can be more easily suspended in the air when the user stands on one leg, making it convenient for the user to swing. By providing the guide rail 12, the user can adjust the relative position of the foot pedal box 11 along the direction of the guide rail 12 before standing on it, thereby ensuring that it moves to a comfortable stepping position to accommodate users of different body types and different foot spacing. At the same time, since both ends of the guide rail 12 are located on both sides of the single-standing bracket 2, by adjusting the position of the foot pedal box 11 relative to the single-standing bracket 2, the position of the user's left and right feet can be adjusted accordingly, eliminating the need to provide two foot pedal boxes 11 for the user's left and right feet to step on separately, effectively improving the adaptability of the leg-swinging fitness machine.

[0059] As an optional implementation, the bottom of the single-standing bracket 2 is provided with an adjustment hole 2a that matches the foot pedal box 11, and the guide rail 12 passes through the adjustment hole 2a. Exemplarily, in this embodiment of the invention, the guide rail 12 is further configured to pass through the adjustment hole 2a at the bottom of the single-standing bracket 2, so that the entire foot pedal box 11 is positioned directly below the U-shaped opening 311, corresponding to the user's standing position. Simultaneously, when adjusting the relative position of the foot pedal box 11 and the single-standing bracket 2, it can pass directly below the single-standing bracket 2, eliminating the need for disassembly and replacement when changing the left and right foot pedal positions, further improving the adaptability of the leg-swinging fitness machine.

[0060] Example 5

[0061] As shown in Figure 9, this embodiment differs from Embodiment 1 in that a leg partition 6 is provided on the base plate 1, and the standing area 4 is located on both sides of the leg partition 6. The height of the leg partition 6 can be any distance from the user's crotch to their feet, allowing the user to stand on top of the leg partition 6 with both legs positioned on either side. The leg partition 6 further enhances the separation of the left and right legs, and also guides the user to swing their legs along the leg partition 6, guiding and correcting the user to swing their legs correctly along the walking direction, preventing improper lateral or diagonal leg swings, and further reducing the probability of kicking the central single-standing support 2 during leg swings, making the leg swing smooth, unobstructed, and sustainable.

[0062] In one embodiment, a leg partition 6 is provided on the base plate 1, and the standing area 4 is located on both sides of the leg partition 6, which is positioned below the U-shaped opening 311. By adopting the above technical solution, when the user stands in the U-shaped opening 311, the leg partition 6 below the U-shaped opening 311 has already separated the user's left and right legs. During leg-swinging movements, the user can directly swing their legs along the preset leg partition 6, thus guiding them to swing their legs along the correct path. This avoids improper leg swinging such as lateral or diagonal swings, improves the standardization of leg swinging, and reduces the probability of kicking the single-standing support 2 during leg swinging, making the leg swinging movement smooth, unobstructed, and sustainable. Simultaneously, the leg partition 6 is not connected to the single-standing support 2, which reduces manufacturing difficulty and achieves a lightweight design.

[0063] Example 6

[0064] In this embodiment, the leg partition 6 is fixedly connected to the single-standing bracket 2. By adopting the above technical solution, the leg partition 6 is fixed to the single-standing bracket 2, resulting in a more compact and simple structure. The leg partition 6 also improves the support stability of the single-standing bracket 2. In particular, the method of fixing the leg partition 6 and the single-standing bracket 2 as an integral structure is even better. One side of the leg partition 6 is fixedly connected to the single-standing bracket 2, and the other side is fixedly connected to the base plate 1. This not only improves the connection stability between the single-standing bracket 2 and the leg partition 6, but also simplifies the installation and operation of the device.

[0065] For example, such as Figure 9As shown, the side support plate 213 includes an upper support section 213a and a lower support section 213b connected in sequence. The lower support section 213b is connected to the base plate 1, and one side of the lower support section 213b is connected to the leg partition 6. The upper support section 213a is located below the orthogonal projection of the tabletop 321 onto the base plate 1. Exemplarily, in this embodiment, by connecting the lower support section 213b near the bottom of the side support plate 213 to the leg partition 6, the overall connection area between the lower support 21 and the base plate 1 is increased, improving structural stability. At the same time, the leg partition 6 and the upper support section 213a are smoothly connected by a transition bevel 213d, providing space for the user to stand. When the user stands on the base plate 1, their legs are located on both sides of the leg partition 6, and the width of the upper support section 213a is relatively small, providing standing space for the user's upper body and avoiding interference. This improves the user experience while ensuring structural stability.

[0066] Example 7

[0067] The difference between this embodiment and other embodiments is that the leg partition 6 can also be independently fixed to the base plate 1, and the leg partition 6 is located below the U-shaped opening 311. In this way, the leg partition 6 is not connected to the single vertical support 2, which reduces the processing difficulty and achieves a lightweight device.

[0068] Example 8

[0069] The difference between this embodiment and other embodiments is that the base plate 1, the single vertical bracket 2, and the support plate 3 are integrally cast.
