Abstract

PROBLEM TO BE SOLVED: To solve problems of a conventional sole plate in which therapeutic effect in conservative therapy, correction effect in prosthetic correction treatment, etc., can be expected only in a state where fundamentally a body weight is imparted to the sole plate and in which therefore, when legs are not used, original function is not demonstrated at all.SOLUTION: This is an insole type sole plate made of silicone rubber. A thick part is in the circumference and the upper face of the body is flat that comes in contact with the sole when in use. The lower face of the body is formed thick in the peripheral part, with a recess provided in the center part. As a result, in a state with the sole plate set in a shoe, a hollow part is formed between the body and the lower face of the shoe. During the walking action, deformation and restoration take place in the manner that this hollow part is crushed, with the walking action supported by the restoring force.

Description

The present invention relates to a foot used for conservative treatment of foot diseases, orthodontic treatment for O-legs, X-legs, etc., elevation for cosmetic purposes, prevention of injury to knees, legs, etc. during sports, etc. This relates to the structure of the bottom plate.

  Conventionally, such a sole plate is a type that is inserted as an insole in shoes or slippers (this applies to the present invention) and a type that is fixed to the sole of a patient's foot (including the case where the sock is attached to both the sole plate) Things are offered. As for the material, there are metals such as stainless steel and aluminum, hard plastic, leather, cork, rubber-like plastic, or those covered with leather or cloth, leather or cloth adhered, and the like.

  Moreover, the shape of the surface (surface which contacts a sole) of the conventional sole board is either a flat thing, or the unevenness | corrugation along the sole shape is provided. The bottom surface of the sole plate is all flat or conforms to the surface shape of the shoe bottom surface. In other words, the conventional sole plate can be said to be a member that raises the shoe sole into a shape suitable for the disease, in terms of a shoe insole type.

Japanese Patent Laid-Open No. 9-098998

  The conventional plantar plate has such a structure and material. Therefore, in conservative therapy, its therapeutic effect, in orthodontic therapy, its orthodontic effect, etc., basically weigh the sole plate. It was something that could only be expected in the state.

  In the case of a sole plate of the type used as an insole for shoes, it is only the foot on the side where the weight is applied when standing upright or walking when the foot of the wearer is pressed and stimulated. In everyday life, besides standing up and walking, there are sleeping postures and sitting postures, but at that time (with swing legs), the sole plate does not perform its original function at all.

For this reason, the industry has been waiting for the emergence of a plantar plate that will continue to irritate the plantar at all times as long as it is worn.

  In light of the present situation as described above, the present inventor has finally made the present invention as a result of intensive research for many years. The feature of the present invention is a shoe insole type silicone rubber sole plate with a thick portion around it. The upper surface of the main body that comes into contact with the sole of the foot when worn is flat, and the lower surface of the main body is formed with a thick peripheral portion and a recess in the central portion, so that it is loaded in shoes, A hollow portion is formed between the main body and the lower surface of the shoe.

  In other words, the sole plate of the present invention is different from the conventional sole plate in which the sole is fitted into the depression that matches the sole shape, and the surface facing the sole is a flat surface in the natural state and receives the foot load. It will be transformed. Therefore, whenever a load is applied, a force is applied to restore this deformation. This means receiving a repulsive force from the sole of the foot. For example, when walking, the sole plate starts to deform when the heel is grounded, and when the heel is raised, the sole is pushed up by the repulsive force. It will be. This means that the sole plate functions like a “trampoline”, and as a result, supports the walking motion.

  As a condition for supporting walking motion, the sole plate of the present invention must be of a shoe insole type. The walking motion is supported on the premise that there is a cavity between the shoe sole and the sole plate main body and that only the sole plate is deformed in such a manner that the cavity collapses when a foot load is applied.

  That is, the force applied to the sole when the body deformed so as to crush the cavity helps to walk, but the magnitude of this force itself is actually quite small. It can be said that smooth walking cannot be achieved without a small force even from the basis of human walking motion. Human gait is the most highly automated movement, and a certain pattern that is determined in detail is composed of repeated one after another. When intervening in this pattern from the outside It is essential to be modest because there is a risk that the pattern will fail.

The material of the sole plate of the present invention is silicone rubber. The reason for adopting silicone rubber is that it is familiar with the skin and is less likely to cause adverse effects such as stuffiness caused by sweating and rash caused by contact with sweat.

  The present invention is a sole plate made of insole type silicone rubber, and has a thick portion around it, the upper surface of the main body that comes into contact with the sole of the wearer is flat, and the lower surface of the main body is formed with a thick peripheral portion. Since the central portion is provided with a recess, a hollow portion is formed between the main body and the lower surface of the shoe when loaded into the shoe, and the following effects are obtained. This is a very advanced invention.

(1) Even if no load is applied to the shoe or the sole plate, the force in the direction of pushing up the sole works. Therefore, in the walking operation that regularly repeats the state where the load is applied and the state where the load is not applied. Will support this.
(2) A force that pushes up the sole of the foot works during walking, but power for that purpose is unnecessary.

(A) (b) is a schematic perspective view which shows an example of the soleplate based on this invention, (a) is the whole, (b) shows the state which cut | disconnected a part. It is a schematic sectional drawing which shows the state which loaded the sole board of the example of FIG. 1 to shoes. FIG. 3 is a schematic cross-sectional view showing a place where a foot is further put and weight is applied in the state of FIG. 2. It is a schematic side view showing an example of a sole plate according to the present invention.

FIGS. 1A and 1B schematically show an example of a sole plate 1 according to the present invention (hereinafter referred to as “the present sole plate 1”), and FIG. (B) depicts a partially cut state. As is apparent from the figure, the sole plate 1 of the present invention is a brace having a flat upper surface A. The material is silicone rubber, and a large number of through holes 11 penetrating the front and back are provided.
Further, the overall shape of the sole plate 1 of the present invention is such that the upper surface A is wide and the lower portion is narrow (that is, the angle θ formed by the upper surface A and the side surface C is an acute angle; Sometimes the expression acute angle is not exact). The lower surface B is formed with a depression in a portion excluding the peripheral wall portion.

  FIG. 2 schematically shows a state in which the sole plate 1 of the present invention shown in FIG. Although a depression is formed in the lower surface B, in the state shown in the figure (that is, a state where no foot is inserted), the cavity 2 formed by the depression on the bottom of the shoe is not deformed.

  Next, FIG. 3 shows a place where the foot F is further put in the state of FIG. The sole plate 1 of the present invention is deformed by this load. The deformation is made so as to crush the cavity 2. As a result, the flat upper surface A is deformed so as to match the sole shape, and the length (width length) of the upper surface A is shortened. Further, the side surface C that is greatly inclined approaches the vertical direction. Although the upper surface A of the entire shape of the sole plate 1 of the present invention is wide in the no-load state, it may be understood that, as a result of the deformation, the shape approximates the shape of the conventional sole plate in the state of FIG.

  2 and 3, the deformation of the sole plate 1 of the present invention has been described with respect to the foot width direction, but the back surface of the sole plate 1 of the present invention is not only in the foot width direction but also in the foot length direction. doing. The concave bay in the length direction of the foot is also deformed so that it collapses in a state where the weight is applied, and exhibits the same functional effect. FIG. 4 is a schematic side view showing that the back surface is recessed in the foot length direction.

In addition, the deformation | transformation of this invention soleplate 1 may be brought about by the pressure originating in the shoes S. FIG. For example, a small shoe will always be deformed, and by tightening a shoelace (or an alternative). Since these are undesirable situations for the present invention, appropriate shoes should be selected. However, since this invention is a proposal about the structure of a soleplate, it does not limit at all about the shoes applied.
