Description

  The present invention relates to a functional device that enables a user to smoothly put an ankle without using a shoe spatula when wearing shoes.

  Leather men's shoes and women's shoes, work safety shoes and cloth, rubber casual shoes, and athletic shoes that are widely used from children to adults, etc. In addition to the convenience of putting the foot into the shoe using slipping while holding it down, it also keeps the shoe open and the shape and hardness of the upper part of the shoe for a long time. It is also a means to protect quality.

  For this reason, the use of a shoe spatula is performed in parallel as a valuable tool for wearing shoes more smoothly while taking care of the shoes, even in shoes with a rear part as a device for wearing shoes in a short time. I came.

  However, when a person wears shoes using a shoe spatula, it involves a movement of bending or sitting down, which is cumbersome. As a result, there are many cases where walking is done with only the tip of the foot while the back is crushed with the footpad, thereby degrading the quality of the shoe. .

  Against this backdrop, in recent years, there has been a growing tendency to require shoes themselves for technical methods that allow them to enter their feet smoothly without using a shoe spatula while standing, and to keep their shoes out of shape. Various attempts have been made to develop shoes that do not require a shoe spatula, by attaching an instrument having versatile properties to the rear part.

  As a known technique, for example, a stiffener is added to the rear part of the shoe to make it harder, and when the shoe is put on, the opening state of the rear part information of the shoe changes due to the pressure of the foot heel, making it difficult to put the foot. Things that improve what (Patent Document 1), things that attached a hard plate with a warp to the back of the shoe to make it easier to put the foot (Patent Document 2), as a mechanism that makes it easier to put the foot A thing which uses a part of a hard support plate attached to the rear part of a shoe as a rotating plate that can be refracted (Patent Document 3), and a shoe vera function imparting device (Patent Document 4) of an inverted U-shaped bar similar to the present invention. is there.

  The technical philosophy of the development without the need for a shoe laver has been focused on the smoothness of wearing shoes, and has been researching and inventing the shape of the equipment to be attached. There is nothing that takes into account the muscular movement of the ankle and the device and the discomfort of the device.

  Patent Document 4 includes the inventor and applicant of the present invention. However, since Patent Document 4 does not have a support portion with a nail at the tip of the column, the column is stuck in the shoe sole and used for a long time. Although it is thought that it will be in the state which penetrates a bottom, and patent document 4 was a shoe spatula function provision apparatus attached to the outer side of shoes, in the thing attached to the outer side, the uncomfortable feeling of contact remained.

  As a result, shoes that have been equipped with a shoe spatula function-imparting device that consists of fixed struts that use hard plates that have been published so far are less unnatural in terms of skin sensation than shoes that are generally used without the device. In addition, it was unsatisfactory, and there was a strong demand for the emergence of a more ideal new shoe vera function-imparting device that was pursued from an ergonomic aspect.

  The present inventor has solved the above-mentioned problems, and further, naturally and smoothly in a state where there is no sense that the shoe situation is used in conjunction with the shoe situation even when wearing shoes. As a result of diligent research to search for a method that can be operated while standing, the shoe spatula function of the present invention has been found by providing the reverse U-shaped rod body with a buttocks sliding portion and a support portion with a nail. We were able to provide a functional instrument.

  That is, the first of the present invention is an inverted U-shaped rod body, which is a flange sliding portion having an inclination at the upper portion of the inverted U-shape, and two curved support columns each provided with a support portion with a claw at each tip. It is a shoe spatula function granting instrument characterized by comprising.

  The second aspect of the present invention is an inverted U-shaped rod body included in the heel of the shoe, wherein the upper portion of the inverted U-shape has an inclination of at least 3 degrees toward the rear of the shoe and the rear of the shoe. It is a shoe spatula function imparting device characterized by comprising two struts having a convex curved direction and provided with a support function with a claw at the tip.

  According to the present invention, the reverse U-shaped rod body is processed so as to be in close contact with the constituent material of the rear portion of the opening portion of the shoe while keeping the shape that does not contact the skin covering the ribs of the human ankle. By creating a shoe spatula function-imparting device that can accurately and quickly exhibit rebound resilience, in the stationary condition where the shoe is not worn, it continues to hold the open state of the upper part of the shoe and the shape and hardness of the rear part. Always provide a situation that makes it easier for people to wear shoes.

  In addition, a support portion with a nail was provided for stable use in order to keep the state where the shoe spatula function-imparting device was normally applied to the shoe even when used for a long time.

  Next, when a person puts his or her foot into the opening part of the shoe, it supports the insertion while naturally responding to the gravity, and after the insertion, the opening state of the upper part of the shoe and the internal shape are restored. Keep the shoe fit across the ankle.

  And while walking, it does not give the person a sense of incongruity that touches the foreign body sensibly on the skin, and conversely, it is useful to satisfy the convenience and comfort that keeps the fit dynamically in conjunction with the ankle muscle movement. Highly comfortable and comfortable shoes.
