Description

Technical Field

[0001] This invention belongs to the field of health technology, and specifically relates to a stretching balance ankle pump training board. Background Technology

[0002] As society develops, people constantly pursue better living conditions and physical health. However, those who sit for long periods or are bedridden lack exercise in their lower limbs, making them prone to problems such as deep vein thrombosis. Balance training, ankle pump exercises, and stretching exercises can help people build a better physical foundation for exercise, which is beneficial for various sports and daily activities, and can provide varying degrees of help and conditioning for people of all ages.

[0003] Currently, many products on the market offer balance training or stretching exercises. Typical balance training products use a combination of cylindrical rollers and flat surfaces, which lacks stability and safety, posing a risk of falls and making them unsuitable for people with weak balance. Stretching products generally use fixed incline boards at a fixed angle, where the user places their feet for stretching exercises. This is often inconvenient for angle adjustment and ankle movement, preventing simultaneous stretching of both legs. Prolonged stretching can easily cause discomfort in the legs and ankles, potentially leading to muscle strains. There is a lack of equipment for ankle pump exercises in seated or standing positions, as these exercises require ankle joint movement at a certain angle, and existing products do not meet these needs.

[0004] Therefore, it is particularly important to develop a device that allows users to perform balance training, as well as appropriate stretching and ankle pump exercises. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a stretching balance ankle pump training board to improve the problems of general balance training products that use a combination of cylindrical rollers and flat plates for balance training, which have poor stability, cannot guarantee safety, and pose a risk of falling, making them unsuitable for people with weak balance abilities.

[0006] To achieve the above and other related objectives, this invention proposes a stretching balance ankle pump training board, comprising:

[0007] Base;

[0008] A support assembly, which is mounted on the base and is provided with a rolling component and / or a sliding component;

[0009] A swing member, which is mounted on the support assembly, and the curved surface of the swing member is in line contact with the rolling support assembly and / or in contact with the sliding assembly;

[0010] A pedal, which is mounted on the top surface of the swing member.

[0011] In one embodiment of the present invention, the support assembly further includes a U-shaped plate, the inner side of which is provided with a rotating shaft and / or an arc-shaped support surface. The rolling assembly includes a roller mounted on the rotating shaft. The roller makes relative rolling contact with the swing member and includes at least two rolling assemblies. The two rolling assemblies are arranged on the front and rear sides of the support assembly, and the two axes of the rotating shaft are parallel. The sliding assembly is mounted on the arc-shaped support surface.

[0012] In one embodiment of the present invention, an axial limiting device is provided between the two sides of the U-shaped plate and the swing member, and the axial limiting device restricts the movement of the swing member in the axial direction.

[0013] In one embodiment of the invention, a damping component is further included, the damping component being adjustablely disposed between the swing member and / or the pedal and the support component and / or the base.

[0014] In one embodiment of the present invention, the damping component may be disposed at the axial limiting device, and the distance between the axial limiting device and the swing member and the magnitude of the axial force are adjusted by the damping component to adjust the magnitude of the frictional force between the damping component and the swing member.

[0015] In one embodiment of the invention, the damping assembly further includes an elastic band / rope, one end of which is mounted on the swing member and / or pedal, and the other end is connected to the support assembly and / or base.

[0016] In one embodiment of the present invention, a handrail bracket is further included. The handrail bracket includes a bracket mounting base, an upright, and a handrail. The bracket mounting base is detachably connected to the base. One end of the upright is fixedly connected to the bracket mounting base, and the other end is fixedly connected to the handrail.

[0017] In one embodiment of the present invention, the base is detachably mounted on one side of the bracket mounting base, and the distance between the base and the bracket mounting base is adjustable. The left and right pedals or left and right swinging components are connected by pulley assemblies or connectors to form asynchronous or synchronous activities.

[0018] In one embodiment of the present invention, the pedal is provided with a plurality of fixing holes, and the pedal is fixed at different positions on the top surface of the swing member through different fixing holes to adjust its rotation center.

[0019] In one embodiment of the present invention, the cross-sectional curve of the cylindrical surface of the oscillating member can be a circle, an ellipse, a parabola, or a cycloid.

[0020] This invention proposes a stretching balance ankle pump training board, employing an axial limiting device to restrict the lateral swaying of the swinging component on the support assembly, ensuring the stability and safety of the device. Simultaneously, a damping component is used. On one hand, elastic ropes / belts increase damping during pedal swing, preventing safety hazards caused by excessive pedal swing angles, and the adjustment method is simple and convenient. On the other hand, adding a damping component at the axial limiting device allows for easy damping adjustment by adjusting the distance between the axial limiting device and the swinging component, as well as the magnitude of the axial force.

[0021] This invention proposes a stretching balance ankle pump training board, employing a special cross-sectional design for the swing component. The cross-sectional curve can be a circle, ellipse, parabola, or cycloid. Line contact support is formed between the rollers and the swing component, with at least two support points distributed before and after the swing center. The axes of the two rollers are parallel to each other, resulting in low friction, flexible rolling, minimal wear, long service life, and reliable performance. Different cross-sectional curves can be used to obtain different training experiences.

[0022] This invention proposes a stretching and balance ankle pump training board with a detachable structure. The left-right distance, front-back distance, and angle between the two foot pedals can be adjusted according to the user's needs. Each foot can move independently, performing different levels of stretching exercises, or the two foot pedals can move in tandem, synchronously or asynchronously. It features self-adjusting stretching and balance training angles and foot spacing, and can be used standing or sitting, reducing the risk of imbalance. It is suitable for different foot sizes and can separately perform stretching, ankle pump exercises, and balance training functions. Attached Figure Description

Detailed Implementation

[0039] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0040] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0041] Please see Figures 1 to 10 As shown, this invention proposes a stretching balance ankle pump training board to improve upon the problems of general balance training products that use a combination of cylindrical rollers and flat plates for balance training, which have poor stability, cannot guarantee safety, and pose a risk of falling, making them unsuitable for people with weak balance abilities. The stretching balance ankle pump training board includes a base 10, a support component 20, a swinging component 30, and a pedal 40. The support component 20 is mounted on the base 10, and the swinging component 30 is rotatably mounted on the support component 20. The pedal 40 is fixedly connected to the swinging component 30 to achieve stretching balance training.

[0042] Please see Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, a sliding component 21 is provided on the support component 20. Specifically, the support component 20 includes a U-shaped plate 22, which can be integrated with the base 10. An arc-shaped support surface 23 is provided on the inner side of the U-shaped plate 22. The sliding component 21 is mounted on the arc-shaped support surface 23, and multiple sliding components 21 are spaced apart on the arc-shaped support surface 23. When the swing member 30 is mounted on the support component 20, the curved surface 31 of the swing member 30 contacts the arc-shaped support surface 23 and slides relative to the sliding component 21. It should be noted that the sliding component 21 can be, for example, a friction plate, a friction circle, or a friction ball.

[0043] Please see Figure 1 , Figure 3 and Figure 6As shown, in another embodiment, a rolling component 24 is provided on the support component 20. Specifically, the support component 20 includes a U-shaped plate 22, which can be integrated with the base 10. A rotating shaft 25 is provided on the inner side of the U-shaped plate 22. The rolling component 24 is rotatably mounted on the rotating shaft 25. When the swing member 30 is mounted on the support component 20, the curved surface 31 of the swing member 30 contacts the rolling component 24 and rolls relative to the rolling component 24. It should be noted that two rolling components 24 are provided on the rotating shaft 25, and the two rolling components 24 are arranged on the front and rear sides of the support component 20. The axes of the rotating shafts 25 of the two rolling components 24 are parallel to each other to increase their contact area and thus ensure their reliability. In some embodiments, a bushing 251 can also be provided between the two rolling components 24 and between the rolling component 24 and the U-shaped plate 22. The bushing 251 is sleeved on the rotating shaft 25 to fix the position of the rolling component 24.

[0044] Please see Figure 9 As shown, in another embodiment, flanges 311 can also be provided on both sides of the curved surface 31 of the swing member 30. The rolling component 40 is located between the flanges 311 on both sides of the curved surface 31 and contacts the flanges 311 to restrict the lateral movement of the swing member 30, thereby improving its stability and safety.

[0045] Please see Figures 1 to 6 As shown, in another embodiment, the sliding component 21 and the rolling component 24 can be simultaneously provided on the support component 20, and when the swing member 30 is installed on the support component 20, the curved surface 31 of the swing member 30 slides relative to the sliding component 21 and rolls relative to the rolling component 25.

[0046] Please see Figures 1 to 6 As shown, in this embodiment, a groove 301 is provided on the curved surface 31 of the swing member 30, and a friction plate 302 is provided in the groove 301. The friction plate 302 slides in contact with the sliding component 21 and / or rolls in contact with the rolling component 24.

[0047] Please see Figure 8As shown, in this embodiment, an arc-shaped through groove 303 is also provided on the swing member 30, and the arc-shaped through groove 303 is arranged along the circumferential direction of the swing member 30. Simultaneously, an axial limiting device 305 is provided between the two sides of the U-shaped plate 22 and the swing member 30. The axial limiting device 305 passes through the arc-shaped through groove 303 to restrict the movement of the swing member 30 in the left-right direction, i.e., axially. It should be noted that the axial limiting device 305 can also be arranged between the side of the swing member 30 and the inner side of the U-shaped plate 22 to restrict the movement of the swing member 30 in the left-right direction and increase structural stability.

[0048] Please see Figures 8 to 12 As shown, in this embodiment, the stretching balance ankle pump training board further includes a damping component 34, which is adjustablely disposed between the swing member 30 and / or the pedal 40 and the support component 20 and / or the base 10. In some embodiments, the damping component 34 may be disposed at the axial limiting device 305. By adjusting the distance and axial force between the axial limiting device 305 and the swing member 20 through the damping component 34, the frictional force between the device and the swing member 30 can be adjusted, thereby achieving damping adjustment.

[0049] Please see Figure 9 and Figure 10 As shown, in another embodiment, the damping component 34 further includes an elastic band / rope, the resistance of which can be adjusted by changing the size of the elastic band. One end of the elastic band is installed on the bottom of the swing member 30 or the pedal 40, and the other end is connected to the support component 20 and / or the base 10. Specifically, the damping component 34 is arranged along the curved surface 31 of the swing member 30, one end of which is fixedly connected to the bottom of the pedal 40 or one end of the curved surface 31 of the swing member 30, and the other end is fixedly connected to the support component 20. Specifically, both ends of the damping component 34 are close to the front and rear sides of the pedal 40, respectively, and a fixed shaft is provided on the U-shaped plate. One end of the damping component 34 is fixedly connected to the bottom of the pedal 40 or one end of the curved surface 31 of the swing member 30, and the other end is fixedly connected to the fixed shaft. It should be noted that the fixed shaft can be the rotating shaft 25. The damping component 34 is provided between the support component 20 and the swing component 30 so that when the position of the pedal 40 changes, it provides a reverse resistance to prevent the pedal 40 from rotating too much, and the resistance of the damping component can be adjusted.

[0050] Please see Figure 11 and Figure 12As shown, in another embodiment, two elastic bands may be provided, one of which is located between the front of the swing member 30 and the pivot 25 on the front side of the support assembly 20, and the other elastic band is located between the rear side of the swing member 30 and the pivot 25 on the rear side of the support assembly 20, or only one elastic band may be used.

[0051] Please see Figure 9 and Figure 10 As shown, in this embodiment, a limiting mechanism can be provided between the swing member 30 and the support assembly 20 to limit the rotation angle of the pedal 40. Specifically, limiting surfaces 201 are provided on the front and rear sides of the support assembly 20. Meanwhile, multiple limiting holes 32 are provided on the swing member 30, and these holes are spaced apart along the circumferential direction of the swing member 30. At least one limiting hole 32 contains a limiting stop bar 33. When the limiting stop bar 33 contacts the limiting surface 201, it restricts the rotation of the pedal 40, thereby limiting the forward and / or backward tilt angles of the pedal 40. It should be noted that when the limiting stop bar 33 is installed in the limiting holes 32 at different positions, the maximum rotation angle of the pedal 40 is different. Alternatively, one limiting stop bar 33 can be installed in each of the limiting holes 32 near the front and rear sides of the swing member 30 to simultaneously limit the forward and backward tilt angles of the pedal 40. It should also be noted that a buffer pad 202 can be provided on the limiting surface 201 so that the limiting stop bar 33 can play a buffering role when it collides with the limiting surface 201.

[0052] Please see Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the pedal 40 is fixedly installed on the top surface of the swing member 30, and multiple fixing holes 41 are provided on the pedal 40. The pedal 40 is fixed at different positions on the top surface of the swing member 30 through different fixing holes 41 to adjust its rotation center. That is, the swing member 30 can be fixedly connected to different fixing holes 41 of the pedal 40 to adjust the center position on the pedal 40, so as to achieve the purpose of adjusting the distance between the user's foot support center and the rotation center of the swing member 40.

[0053] Please see Figure 9 and Figure 10As shown, in another embodiment, a boss 306 can be provided on the top surface of the swing member 30, and the boss 306 is fixedly connected to the pedal 40 to facilitate adjustment of the position of the pedal 40. It should be noted that the swing member 30 can be a cylindrical surface similar to a semi-circular piece or composed of at least two bent tubes and a support surface for mounting the pedal 40. It should also be noted that the cross-sectional curve of the curved surface of the swing member 30 can be a circle, ellipse, parabola, or cycloid.

[0054] Please see Figure 1 and Figure 2 As shown, in this embodiment, the stretching balance ankle pump training board further includes a handrail support 70. The handrail support 70 includes a support mounting base 71, a vertical pole 72, and a handrail 73. The support mounting base 71 is detachably connected to the base 10. One end of the vertical pole 72 is fixedly connected to the support mounting base 71, and the other end is fixedly connected to the handrail 73. It should be noted that the vertical pole 72 can be configured as a three-point support rod to improve its reliability and stability.

[0055] Please see Figure 1 and Figure 2 As shown, in this embodiment, two bases 10 are detachably installed on one side of the bracket mounting base 71, and the distance between the bases 10 and the bracket mounting base 71 is adjustable. Specifically, a plurality of adjustment positioning holes 711 are provided on the bracket mounting base 71. By fixing the bases 10 to different adjustment mounting holes 711, the distance between the left and right pedals 40 can be adjusted.

[0056] Please see Figure 1 and Figure 3As shown, in this embodiment, the two pedals 40 are connected by the pulley assembly 50 to enable asynchronous movement between them. Specifically, the pulley assembly 50 includes a mounting frame 51, a first rotating shaft 52, a second rotating shaft 53, a pulley mounting plate 54, a pulley 55, and a rope component 56. The mounting frame 51 is fixedly mounted on the base 10 and located between the two pedals 40. The first rotating shaft 52 is rotatably connected to the mounting frame 51, and its rotation axis is perpendicular to the left-right symmetry plane between the two pedals 40. One end of the second rotating shaft 53 is fixedly connected to the first rotating shaft 52, and the other end is rotatably connected to the pulley mounting plate 54. The axis of the first rotating shaft 52 and the axis of the second rotating shaft 53 are perpendicular to each other. The pulley 55 is rotatably mounted on the pulley mounting plate 54, and the pulley mounting plate 54 is, for example, a U-shaped mounting plate to facilitate the installation of the pulley 55. The two ends of the rope member 56 are respectively fixedly connected to the front ends of the two pedals 40 or fixedly connected to the swing member 30 through the lugs 561. The rope member 56 is wound around the pulley 55. When one of the pedals 40 tilts forward (backward), the pulley 55 is driven by the rope member 56 to rotate adaptively around the first rotating shaft 52 and the second rotating shaft 53, thereby driving the other pedal 40 to tilt backward (forward). This creates asynchronous movement between the two pedals 40, which facilitates the user to adjust the stretching angle by moving their ankles, realizing the function of controllable stretching angle and stretching the legs separately.

[0057] It should be noted that in asynchronous motion mode, the two pedals move up and down in a step-like linkage, with their rotation center located in the middle of the foot, making it easy for the user to adjust the center of gravity of the two legs when leaning forward and backward.

[0058] In another embodiment, the two pedals 40 are connected by a connector, which can be a connecting rod. The two ends of the connecting rod are fixedly connected between the two pedals 40 or between the two swing members 30 by hooks, so that the two pedals 40 can move synchronously.

[0059] It should be noted that in the synchronized state, the two pedals 40 move synchronously, and their rotation center is located in the middle of the foot, which makes it easy for the user to adjust the center of gravity position when leaning forward and backward.

[0060] Please see Figure 13 As shown, in this embodiment, the bottom of the base 10 is also provided with a structural reinforcement 101 and a support pad 102. The structural reinforcement 101 enhances the load-bearing capacity of the base 10, and the support pad 102 increases the friction between the base 10 and the ground, thereby determining the relative position of the base 10 and the ground.

[0061] This invention proposes a stretching balance ankle pump training board, employing an axial limiting device to restrict the lateral swaying of the swinging component on the support assembly, ensuring the stability and safety of the device. Simultaneously, a damping component is used. On one hand, elastic ropes / belts increase damping during pedal swing, preventing safety hazards caused by excessive pedal swing angles, and the adjustment method is simple and convenient. On the other hand, adding a damping component at the axial limiting device allows for easy damping adjustment by adjusting the distance between the axial limiting device and the swinging component, as well as the magnitude of the axial force.

[0062] This invention proposes a stretching balance ankle pump training board, which employs a special cross-sectional design for the swinging component. The cross-sectional curve can be a circle, ellipse, parabola, or cycloid. A line contact support is formed between the rollers and the swinging component, with at least two support points located before and after the swinging center, and the axes of the two rollers being parallel to each other.

[0063] This invention proposes a stretching and balance ankle pump training board with a detachable structure. The left-right distance, front-back distance, and angle between the two foot pedals can be adjusted according to the user's needs. Each foot can move independently, performing different levels of stretching exercises, or the two foot pedals can move in tandem, synchronously or asynchronously. It features self-adjusting stretching and balance training angles and foot spacing, and can be used standing or sitting, reducing the risk of imbalance. It is suitable for different foot sizes and can separately perform stretching, ankle pump exercises, and balance training functions.
