Description

  The present invention relates to a foot support device for supporting a toe when a handicapped person who lacks the ability to support the toe or another handicapped person of the lower limbs performs rehabilitation.

  According to statistics from the medical competent government agency, cerebrovascular disease is one of the top ten causes of death in Taiwan. In addition, limb disorders due to illness, traffic accidents, sports disorders, etc. tend to increase every year. Some chronic illnesses can cause side effects such as paralysis of the patient's lower limbs and poor muscle strength. Therefore, long-term rehabilitation is required. In such long-term rehabilitation, an appropriate auxiliary device is required. A disabled person who does not have the power of the toes and cannot perform even a simple walking motion needs an auxiliary device for supporting the toes.

  The conventional foot support is positioned and supported in the vertical and horizontal directions, and generates a walking action on the foot so that the foot is interlocked with the shin. This is a great help for patients and their families, but it can contract muscles for walking in active rehabilitation to restore walking ability and increase muscle strength of the lower limbs appropriately, Muscle atrophy can be prevented and bedsores can be prevented from occurring.

However, the conventional foot support has the following drawbacks.
(A) The ankle joint becomes hard easily. That is, the conventional foot support device is positioned at a right angle formed by the vertical and horizontal directions, and generates a holding support action between the shin and the foot tip. For this reason, the tip of the foot and the shin are in a state of holding an angle of 90 degrees as needed, making it difficult to move the joint. Therefore, the ankle joint is easily hardened.
(B) Walking motion becomes unnatural. That is, since the state where the toes and shins form 90 degrees is maintained, when walking, the lower limbs are simply raised and lowered, and there is no space for allowing motion deviation. For this reason, the motion of walking becomes hard and unnatural. Therefore, there may be a sense of incongruity.
(C) It is inconvenient and limited. That is, since the conventional foot support is made based on the patient's body shape, it takes time to complete. In addition, it is inconvenient for persons with disabilities in the lower limbs because the patient himself / herself must go from ordering to trial confirmation and receipt of goods. In addition, since the body shape is completely matched to the patient's body shape, if the body shape changes due to muscle atrophy, or conversely obesity, the support device does not conform to the actual body shape and is restricted in use.

  An object of the present invention is to provide a foot support that can achieve a natural walking action and is convenient for use without feeling uncomfortable.

A specific example will be given and described below in order to describe the structure and features of the foot support in such a configuration in detail.

  As disclosed in FIGS. 1 and 2, a foot support 1 according to the present invention includes an upper support 2, a lower support 3, curved connection members 4, a plurality of elastic members S, and both coupling members. 5 and the foot support 6.

  The upper support 2 includes a curved portion 21 that covers the shin, and a slide guide portion 23 that extends downward from a substantially central position of the curved portion 21 and is provided with a nut 22 at the end.

  The lower support 3 includes a plate-shaped slide guide seat 32 having a concave groove 31 formed therein, a first slide groove 33 formed in a vertical direction at a substantially central position of the slide guide seat 32, and the slide guide seat 32. An arc-shaped cover portion 35 formed integrally on both lower ends and having a second slide groove 34 is provided. The slide guide portion 23 of the upper support 2 is inserted into the concave groove 31 and positioned with a screw.

  The connection member 4 has a screw hole 41 for connecting to the second slide groove 34 at one end, and the screw hole 41 is formed at the center of the other end as a shift stopper 43 to form a screw hole. A screw is passed through 41 and screwed into the second slide groove 34 of the lower support 3.

  The plurality of elastic members S are compressed by a load and have a structure that returns to their original state when released from the load, and are enclosed on both sides of the lower end of the shift stopper 43.

  The connecting member 5 has a storage groove 51 formed at the upper end side, a screw hole 53 is formed at a substantially central position of the storage groove 51, an insertion groove 52 is formed at the lower end side, and a longitudinal position is formed at the central position. A third slide groove 54 is formed along the direction, and the shift stopper 43 of the connection member 4 is inserted into the storage groove 51.

  The foot support portion 6 includes a support portion 61 that is curved in accordance with the shape of the foot tip, and a slide portion 63 is integrally formed by extending upward from a position that supports the center of gravity of both side surfaces. A nut 62 is fitted on the upper end. The slide part 63 is inserted into the insertion groove 52 of the connecting member 5 and connected with a screw.

  The foot support 7 composed of the above-described members can support the user's foot and can provide an auxiliary action, thereby producing an effect of supporting a walking operation convenient for the user (FIG. 3). (See the structure disclosed in)

  As disclosed in FIG. 3, FIG. 3A, FIG. 4, and FIG. 4A, when the user performs an action of raising the foot tip P, the heel P1 rises upward and the center of gravity of the human body tilts forward. Such forward tilting operation applies pressure in the counterclockwise direction to the lower support 3. For this reason, the elastic member 2 located on the left side of the shift stopper 43 is reduced by receiving pressure (see FIG. 3A). When the user lowers the foottip P, the calf P2 is inclined rearward because the center of gravity of the human body is rearward. Such backward tilting operation causes a pressure in the direction opposite to the clockwise direction against the lower support 3. In this case, the elastic member S located on the right side of the shift stop portion receives pressure and contracts (see FIG. 4A). For this reason, a deviation of a predetermined angle (90 ° ± 15 °) and a deviation of the position occur due to the elasticity of the elastic member S that expands and contracts (the characteristic that it is reduced by receiving pressure and returns when the pressure is released). The user can walk naturally without discomfort. In other words, when the foot leaves the ground, the support has an angle of 90 ° without the elastic member S being compressed. Therefore, when a foot leaves the ground, it can walk naturally without friction with the ground.

  In this device, the upper support 2 is fixed to the calf part by using a hook-and-loop fastener or the like, or the lower support 3 is constrained to a position close to the heel and positioned. Can provide convenient installation. Furthermore, by providing a soft pad inside each member of the foot support portion according to the present invention, it is possible to avoid giving a sense of incongruity to a portion such as a calf or a heel.

  Furthermore, the foot support according to the present invention is configured so that the connecting position can be freely adjusted by forming a slide groove in the component member. Therefore, since the size of the support can be adjusted in accordance with the size of the user's foot, it is not necessary to create the support tool in accordance with the size of the user's foot as seen in the prior art.

  The above is a preferred embodiment of the present invention, and does not limit the scope of implementation of the present invention. Therefore, any modifications or changes that can be made by those skilled in the art, which are made within the spirit of the present invention and have an equivalent effect on the present invention, belong to the scope of the utility model registration claim of the present invention.
