Abstract
Description
Technical Field
[0001] The utility model relates to training equipment, in particular to a device for training plantar joint balance. Background Art
[0002] The sole of the foot refers to the sole of the foot, which, in addition to the toes, also includes the tarsal bones, metatarsal bones, ligaments, and muscles that together form the convex arch of the foot.
[0003] The sole of the foot is the part of the foot that contacts the ground and supports the body's gravity. The sole of the foot contains multiple phalanges, including the big toe, which make up the toes. The arch of the foot is divided into a longitudinal arch and a transverse arch, with the longitudinal arch further divided into a medial longitudinal arch and a lateral longitudinal arch. The medial longitudinal arch is formed by the tarsal bones (calcaneus, talus, navicular, cuneiform, and multiple metatarsal bones on the medial side), with the highest point of the arch being the talus. The lateral longitudinal arch is formed by the tarsal bones (calcaneus, cuboid, and metatarsal bones on the lateral side), with the highest point of the arch being the cuboid. The transverse arch is formed by the tarsal bones (cuboidal, cuneiform, and metatarsal bones), with the highest point of the arch being the intermediate cuneiform.
[0004] The forefoot includes the scattered phalanges, first metatarsal, medial cuneiform, navicular, fifth metatarsal, and transverse arch, making it more flexible on the plantar plane. The rearfoot, on the other hand, is home to the talus, cuboid, calcaneus, and longitudinal arch. These bones are generally located below the tibia, resulting in a more integrated structure. This results in greater integration of the rearfoot and greater flexibility in the forefoot. Generally, when the rearfoot is partially tilted, the entire plantar will tilt as well, whereas when the forefoot is partially tilted, the entire plantar will not tilt.
[0005] However, the equipment currently used for plantar balance training basically all adopts an integrated pedal, which results in the inability to carry out targeted subdivision training according to the degree of freedom of each part of the plantar when performing balance training for plantar diseases. Utility Model Content
[0006] The purpose of the present invention is to provide a device for plantar joint balance training to solve the problems raised in the above background technology.
[0007] To achieve the above objectives, the present invention provides the following technical solutions:
[0008] A plantar joint balance training device comprises a plurality of balance boards and a rotating shaft for connecting the plurality of balance boards in series;
[0009] Wherein, one side of the balance plate is an arc surface, and the other side is a plane, and the plane and the arc surface have a smooth transition;
[0010] A central hole is formed through the balance plate, and the central hole is arranged along the thickness direction of the balance plate; the rotating shaft passes through the central hole, connecting the plurality of balance plates in series;

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0029] See also Figures 1 to 3 As an embodiment of the present invention, the plantar joint balance training device includes a plurality of balance boards 1 and a rotating shaft 2 for connecting the plurality of balance boards 1 in series;
[0030] One side of the balance board 1 is a circular arc surface, and the other side is a flat surface, and the flat surface and the circular arc surface have a smooth transition;
[0031] A central hole is formed on the balance plate 1 and is arranged along the thickness direction of the balance plate 1; the rotating shaft 2 passes through the central hole to connect the plurality of balance plates 1 in series;
[0032] The balance board 1 can rotate freely around the rotation shaft 2 , and a plurality of balance boards 1 are stacked on each other along the thickness direction thereof.
[0033] In this embodiment, since the balance board 1 is rotatably matched with the rotating shaft 2 and a plurality of balance boards 1 are independently stacked in series on the rotating shaft 2 , the balance boards 1 can deflect independently of each other.
[0034] If balance training for the forefoot is required, part of the balance board 1 can be rotated 180 degrees, and the back foot is placed on a flat surface, while the forefoot is placed on a curved surface; when the patient stands on the device, the back foot is in contact with the flat surface of the balance board 1, so there is no need to adjust the balance, while the forefoot is in contact with the curved surface and is unstable; therefore, the balance of the forefoot can be trained.
[0035] Accordingly, if the balance of the back foot needs to be trained, the forefoot is placed on a flat surface and the back foot is placed on an arc surface; after the patient stands, the balance of the back foot can be trained.
[0036] Of course, you can also put the entire sole of your foot on the arc surface without deflecting the balance board 1, and then you can train the balance of the entire sole of your foot.
[0037] In the present invention, when performing plantar joint balance training, adjustments can be made accordingly according to the needs of the actual training parts, including forefoot balance training, rearfoot balance training, and full-foot balance training; in addition, since each balance board 1 can deflect independently of each other, during the training process, if a certain part of the sole of the foot is unbalanced, it will not affect the following tilt of other parts.
[0038] As a further solution of the present invention, a plurality of the balancing plates 1 are stacked to form a plate group structure, and the two ends of the rotating shaft 2 respectively pass through the two ends of the plate group structure, and a limit nut 3 is provided on the passing section;
[0039] One side of the limiting nut 3 is in close contact with the surface of a balancing plate 1 located at the edge of the plate group structure, so as to eliminate the gap between two adjacent balancing plates 1 in the thickness direction of the balancing plates 1 .
[0040] In this embodiment, since the limiting nuts 3 are threadedly provided at both ends of the rotating shaft 2, the limiting nuts 3 at both ends can eliminate the gap between the two adjacent balance boards 1, thereby preventing the gap between the two adjacent balance boards 1 from causing injury to the skin and soft tissue of the soles of the feet when the two balance boards 1 rotate relative to each other during balance training.
[0041] On the other hand, after the detachable limiting nut 3 is removed, the number of balance boards 1 can be increased or decreased according to the size of the sole of the foot.
[0042] As a further solution of the present invention, the balance board 1 is divided into two specifications: a small balance block 101 and a large balance block 102. The arc surface radius and arc length of the large balance block 102 and the small balance block 101 are equal, and the plane lengths of the two are the same;
[0043] The size of the large balancing weight 102 in the thickness direction is larger than that of the small balancing weight 101 .
[0044] In this embodiment, when using the device, due to the characteristics of the plantar joint structure of the human body, generally, the integrity of the rear sole is higher, while the flexibility of the forefoot is higher. Therefore, the forefoot corresponds to the plane or arc surface of the small balance block 101, and the rear sole corresponds to the arc surface or plane of the large balance block 102.
[0045] As a further solution of the present invention, a plurality of arc surfaces arranged in the same direction form a training surface, and a plurality of plane surfaces arranged in the same direction form a support surface;
[0046] A positioning structure is provided between the plurality of balancing plates 1 forming the support surface, so as to restrict the plurality of balancing plates 1 forming the support surface from rotating relative to each other.
[0047] In this embodiment, the positioning structure can keep the support surface as the force contact surface stable, and will not cause the planes forming the support surface to deflect from each other, thereby ensuring that the non-training part is stable;
[0048] It should be noted that if full-foot balance training is required, there is only a training surface but no support surface, and positioning restrictions are not required at this time.
[0049] As a further solution of the present invention, a positioning hole is opened on the balance plate 1 along its thickness direction, and the positioning hole passes through the balance plate 1;
[0050] The positioning structure includes a positioning rod 4 , and the positioning rod 4 is inserted into positioning holes on the plurality of balancing boards 1 forming a support surface.
[0051] In this embodiment, when the positioning rods 4 are inserted into the positioning holes on the multiple balance boards 1 serving as the support surface, the multiple balance boards 1 serving as the support surface cannot rotate relative to each other. Of course, the specific number of the multiple balance boards 1 serving as the support surface can also be adjusted according to needs; providing support stability, while the multiple balance boards 1 serving as the training surface are not restricted and can deflect relative to each other around the rotation axis 2, thereby achieving the effect of balance training.
[0052] As a further solution of the present invention, the balance board 1 is made of wood or plastic.
[0053] In this embodiment, the balance board 1 made of wood or plastic is less rigid and less likely to cause secondary damage. Moreover, when the balance board 1 made of wood or plastic comes into contact with the sole of the foot, especially in winter, it produces less temperature stress reaction.
[0054] As a further solution of the present invention, the positioning rod 4 and the rotating shaft 2 are both made of metal materials, such as iron, steel, and copper.
[0055] In this embodiment, the positioning rod 4 and the rotating shaft 2 made of metal can withstand greater torque and pressure, are less likely to deform and break, and ensure a sufficiently long service life.
[0056] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
