Description

  In the present invention, the mounting point of the belt with hook-and-loop fastener and the folded part are located near the heel, and the reinforcing material inside the heel is provided with strong and weak parts to secure the tightening of the mouth and heel, and the inside of the shoe The present invention relates to an adult heel stabilizing belt shoe that can easily stabilize a foot.

  When a human walks, his body walks with a balance in front, back, left, right and up and down. Human walking cycles are classified into a stance phase and a swing phase. Furthermore, in the stance phase, it is subdivided into heel contact, sole contact, mid stance, heel takeoff, and toe takeoff. In the swing phase, it is subdivided into an acceleration phase, a middle swing phase, and a deceleration phase. Looking at the center of gravity movement (trajectory) of walking during the stance phase of the walking cycle from the soles, the ideal center of gravity movement starts slightly outside the center of the heel, moves to the little toe side, passes through the center, and finally exits with the toe. It is to go.

  Due to the large size and wearing shoes that do not fit the shape of the feet, the feet move significantly in the shoes during the stance phase. In the walking cycle, if the heel is not stabilized due to the heel contact at the beginning of the stance phase and falls down inward, it is difficult to move the center of gravity toward the little toe, which is the ideal center of gravity movement. On the other hand, when the heel falls outward, it is difficult to move the center of gravity to the toe. As described above, these problems in which the heel is not stabilized greatly affect the movement of the center of gravity of walking, and not only accumulate fatigue of the foot due to inefficient walking, but also lead to various foot health problems.

  In the case of the conventional low-cut walking shoes, it is difficult to prevent the feet from slipping forward, particularly when walking downhill in an outdoor environment, which may cause an obstacle to the toe portion of the wearer. Originally, in order to prevent the feet from slipping forward in such a situation, it was necessary to wear high-cut trekking shoes or the like and firmly fix the ankles (Patent Document 1). However, this is not a full-fledged activity.For example, walking on a flat ground or walking in an urban area is often the case when walking in a satoyama area. Often wear shoes.

  In the case of low-cut walking shoes, it is common to attach and detach with shoelaces, and if the shape of the foot, especially the shape of the heel part, does not match the shoe, it is difficult to fix the foot firmly only by tightening the shoelace, This caused the feet to slip forward. Also, since putting on and taking off with shoelaces is a laborious work especially for elderly people etc., there are many shoes that can be attached and detached using zippers provided on the side parts of shoes, In such a case, it is not possible to adjust the looseness of the string or the like, and it becomes more difficult to firmly fix the foot to the shoe.

To date, many shoes have been proposed for the purpose of preventing forward slippage of the foot by firmly fixing the ankle and heel in the shoe. For example, as in Patent Literature 2, there is a device in which a cut portion made of an elastic member is provided on an outer surface or an inner surface of a rear instep portion, and a heel portion is held by a tightening band that bridges the cut portion. However, in this case, since the ankle is fixed simply by being sandwiched between the front and the back of the heel portion of the shoe and the front of the upper, there is a possibility that both sides of the heel may open outward due to pressure from the front and rear. In such a case, the more the restraint is made, the more the sides open, and the stability of the heel may not be obtained. Therefore, it is not possible to solve the fundamental problem of lateral blur of the heel due to mismatch between the shape of the heel of the shoe and the shape of the heel of the foot. It may also cause the heel to move forward.

  Further, as disclosed in Patent Document 3, there is a proposal of a tightening structure of a track and field shoe for improving fit and stability from a heel portion to an arch portion. In this document, a belt-shaped tightening member is arranged from the heel portion to the inner instep side or the outer instep side, and the structure is tightened to the instep portion through the folded portion, and the tightening member is provided by providing a counter member on the heel portion. When tightened, the upper end of the heel member is pulled forward and downward, so that the heel member of the shoe is brought into close contact with the shape of the Achilles tendon of the foot. However, since the tightening member extends from above the heel portion and is long from the folded portion to the fixed portion, it is difficult to maintain the tightening effect. Furthermore, since the binding member is fixed above the heel, the upper heel may fall forward when strongly tightened, and the fixed foot may be loosened when worn, and the heel may not be fixed. . Also, since it is for competitions, it takes time to wear and is not suitable for general shoes.

  As described above, there are many foot health problems after wearing due to inconsistency between the shape of the foot and the shape of the shoe, particularly due to poor fit inside the shoe at the heel. With the conventional method of fixing the upper with shoelaces or hook-and-loop fasteners, the foot is fixed by the pressure from the terminal part of the upper part by tightening to the front part, eliminating the mismatch in size and shape of the heel part Adjustment is difficult. As a result, when the shape of the foot, especially the width of the heel, is smaller than the width of the heel part of the shoe, the foot tends to slide forward in the shoe, causing a health problem of the toe of the foot Becomes Further, when the foot moves more than necessary inside the shoe, it becomes difficult to transmit the force of the sole to the sole, which may cause fatigue during walking. Conversely, when the heel portion of the foot is large relative to the inner size of the heel of the shoe, and when the heel portion is thick, excessive friction is caused on the heel portion and the like, causing shoe rubbing and the like.

  The present invention has been made in consideration of such a problem, and has a long belt for holding the mouth, and has a belt starting point near the heel, and is provided near the heel on the opposite side. The belt is turned upside down through the ring for folding the belt and folded back, the wearing mouth is pressed down, and the fixing position of the belt is arbitrarily adjusted with the hook-and-loop fastener. In addition, a crescent-shaped reinforcing member is fixed to the inside of the heel portion, and the reinforcing member is used to provide hardness to strength, so that it is possible to cope with individual feet having various shapes. Therefore, the trouble of searching for a shoe that matches the shape of each foot is eliminated, and the heel in the shoe caused by the size mismatch, that is, the movement and blur of the foot, is suppressed, and especially the toe of the toe generated by the front slip of the foot. The effect of preventing deformation and obstacles can be expected.

  In order to achieve the above object, the adult heel stabilizing belt shoe according to claim 1 has a long belt for holding down a mouth, and a starting point for attaching the belt near a heel portion, and near an opposite heel portion. Invert the belt through the ring for folding the belt provided in, press down the wearing mouth, adjust the fixing position of the belt arbitrarily with hook-and-loop fastener, and fix the half moon shaped reinforcing material inside the heel part, It is characterized in that the reinforcing material is formed so that the rear of the heel is hard and the sides of the heel are soft.

  The heel stabilizing belt shoe for adults according to claim 2, characterized in that the half-moon-shaped reinforcing member is made of a synthetic material of ethylene vinyl acetate copolymer, thermoplastic polyurethane and polyester, and the rear portion of the heel is double-bonded with the same material. And

  According to the present invention, both the heel and the heel are restrained simultaneously with the restraint of the front of the upper, so that the pressure on the front of the upper and the pressure on the both sides of the heel can be simultaneously applied, so that the heel is securely fixed. . Therefore, the effect of preventing the heel in the shoe caused by the inconsistency of the shape and size of each foot, that is, the movement and blur of the foot, and the prevention of the deformation of the toes and the obstacles particularly caused by the front slip of the foot. Can be expected. It can prevent the front slippage of the foot, which has been difficult with low-cut shoes, and is easy to put on and take off because it has a simple structure and can be used by elderly people.

It is a perspective view of the adult heel stabilization belt shoe inside the same right foot. It is explanatory drawing of the state which removed the wearing belt of the heel stabilization belt shoes for adults of the same right foot. It is explanatory drawing of the state which removed the wearing belt of the heel stabilization belt shoes for adults inside the same right foot. It is explanatory drawing of the reinforcement member inserted in the same heel part. It is an enlarged view of the ring part of the turning point of the wearing mouth belt.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIGS. 1 to 4 are perspective views showing an adult heel stabilizing belt shoe according to an embodiment of the present invention. A starting point A of a mouth holding belt 4 is attached to a heel outer reinforcing portion 3 of a heel portion 2 of a shoe body 1. The belt 4, which has been fixed and pressed back through the belt ring 5 attached to the heel outer reinforcing portion 3 ′ of the opposed heel portion 2 which becomes the folded portion C on the opposite side by pressing the wearing mouth B, passes through the presser guide 6 to the starting point. It is arranged to be inverted to the A side. The belt ring 5 is formed in an elongated rectangular shape, and a support piece 7 fixed to the heel outer reinforcing portion 3 ′ is inserted through the lower straight portion 5 a of the ring in a folded manner, and a metal member is inserted into the upper straight portion 5 b of the ring. And the belt 4 is folded back so as to wind around the cylindrical roll 8 (see FIG. 6).

  Further, as shown in FIG. 3, the surface fastener 9 is fixed to the lower surface 4 a of the front end portion of the belt 4, and the upper surface 4 b of the belt 4 at a position where the corresponding surface fastener 10 hits the upper part of the mouth B as shown in FIG. It is stuck to. Reference numeral 11 denotes a metal guide ring fixed to the inner side part D, which is a guide opening for the belt 4 (FIG. 4).

  Reference numeral 12 denotes a reinforcing member provided inside the heel portion 2 of the shoe body 1, which has a half-moon shape corresponding to the heel shape, has a hard portion 12a that abuts on the rear portion of the heel, and has a portion that abuts the left and right sides 13 of the heel. The hardness of 12b was softened. Specifically, the crescent-shaped reinforcing member 12 is a synthetic material of ethylene vinyl acetate copolymer (EVA), thermoplastic polyurethane (TPU), and polyester, and is made of a material having a thickness of 1.2 mm. The contacting portion 12a is made of the same material and adhered thereto to add hardness. This prevents the heel portion 2 from falling forward at the portion 12a that contacts the rear portion of the hardened heel when the belt 4 is pulled and the shoe opening B is narrowed, and the portion 12b that contacts the both side portions of the heel. But it is narrowed down so that it wraps around the foot and fits. Thus, the heel is firmly fixed to the heel portion 2.

  The belt length of the belt 4 of the present invention is longer than usual because the starting point portion A and the folded portion C retreat to the vicinity of the heel portion 2. Therefore, in a state where the hook-and-loop fastener 9 is peeled off and the wearing mouth B is opened, the shoe falls down on the inside of the shoe, and there is a concern that the opposite shoe may step on the end of the belt 4 and cause a fall. In order to prevent this, a pressing guide 6 for passing the belt 4 is provided above the belt turning portion C, and the belt end is regulated by passing the turned back belt 4 when attaching / detaching the shoes, so that the belt falls down inside the shoes. I try not to.

Next, how to use the present invention will be described.
Put the foot in the mouth B of the shoe body 1, fold back the side foot holding belt 4 through the belt ring 5, and squeeze it toward the starting point A side of the belt to fix the instep of the foot to the mouth B Is done. At this time, the heel portion 2 is pulled in the forward direction of the shoe body 1 by the drawing and drawing of the belt 4, but the movement is restricted by the reinforcing member 12 mounted in the heel portion 2. That is, since the reinforcing member 12 has a hardened portion 12a that contacts the rear portion of the heel, the heel portion is prevented from falling forward, and the hardness of the portions 12b that contact both sides of the heel is softened. The portions 12b abutting on both sides are squeezed so as to enclose the feet. Thereby, the restraint on both sides of the heel is performed simultaneously with the restraint on the front of the instep, thereby suppressing the heel blur, stabilizing the foot inside the shoe, and suppressing the forward slip of the foot.

  In addition, since the starting point portion A and the folded portion C are retracted and attached to the vicinity of the heel portion 2 of the wearing mouth holding belt 4, the belt length becomes longer than usual, the hook-and-loop fastener 9 is opened, and the wearing mouth B is opened. Is opened, the tip of the belt 4 hangs down inside the shoe, and the belt 4 is passed through the presser guide 6 provided on the downstream side of the belt turning-back portion C in order to prevent a problem that the end of the belt is stepped on by the shoe on the opposite side.

  In addition, the friction between the belt 4 and the belt ring 5 is reduced by the cylindrical metal roll 8 inserted through the belt ring 5 of the belt turn-back portion C, so that the belt tightening and loosening operation is smooth. .
