Description

  The present invention relates to a shoelace tightening strap capable of tightening and releasing the upper portion of a shoelace with a single touch and a shoelace provided with the shoelace tightening strap.

  Conventionally, in lace shoes such as sports shoes, a single shoelace is sequentially tightened from the toes through a lace hole provided along the inner edge of the upper part of the lace shoe and tightened. A method has been used. However, the method of tightening one shoelace from the toes in order is not limited to a specific hole that fits the shape of the foot, and it can be loosened during use or the tip of the shoelace The work of tying shoelaces is troublesome.

  In order to solve such problems, tightening fixtures and hoisting jigs to be attached to shoelaces have been developed, but many of them are bulky, have a complicated structure, and are difficult to operate. There was a problem such as a tingling.

  Conventionally, proposals have been made to solve the problems in the above tightening means. For example, it is formed in a state in which a net-like cover is in close contact with the outer periphery of the string core so as to be continuous in the longitudinal direction thereof, and an uneven surface is formed on the outer periphery of the string core. A "string" (refer patent document 1) is proposed and it becomes a well-known technique.

  However, the proposal of the “string and shoelace” is a proposal that has a continuous anti-slip function continuous over the entire outer periphery of the string, is easy to manufacture, is versatile, and has excellent aesthetics. Since the conventional tying of the lace has not been improved, it is possible to improve the troublesomeness of tying the lace and the problem of loosening of the lace during the tying. It wasn't.

  Further, the present invention is characterized in that a through hole is formed at one end, and has a linear body having elasticity, and a locking portion attached to the other end of the body and configured to be engageable with the through hole. "Linear body and shoes" (see Patent Document 2) has been proposed and is a known technique.

  However, the proposal of the “linear body and shoes” provides a shoe that can be easily put on and taken off in a state in which the shoe is attached by attaching an elastic linear body to the shoe, or is not easily loosened. Although it is a proposal that can be done, the tightening force depends on the stretching force of the linear body, so the fit and tightening state when the shoelace desired by the user is tightened in the optimum state is always maintained It was not a proposal with functionality.

  Moreover, it is a shoelace attached to shoes, Comprising: It hangs only between a pair of left and right string passage holes in each step in the front-rear direction among a plurality of string passage holes arranged on both sides of a slit provided in the upper part of the shoe. One stretchable and deformable string having a length dimension to be passed and attached, provided with a fixed part provided at each end and fixed to the string passage hole, and a connecting part provided between the fixed parts The fixed portion is formed with a step between a large-diameter portion and a small-diameter portion having different diameter dimensions in a natural length state, and the large-diameter portion is reduced in diameter while being stretched from the natural length. The step is configured to be flattened, and the connecting portion is spanned between the pair of string passage holes by engaging the step of each of the fixed portions with each of the pair of string passage holes. `` Shoelaces and shoes equipped with them '' (patent text) This is a well-known technique.

  However, the proposal of the “shoelace and the shoe equipped with it” is very easy to attach to the shoe and tighten the upper, and to take off the shoe and to adjust the tightening of the upper, This is a proposal that effectively increases the degree of freedom in exterior design, but the tip of the fixed part always protrudes outward, which makes it look bad and injures your body and opponent. There was a problem with safety.

  Also, a shoelace to be attached to a shoelace, which is inserted into a pair of left and right shoelace passage holes of a plurality of shoelace passage holes arranged on the left and right upper wings of the shoelace, and attached in a looped manner. When attaching the shoelace to the shoelace body having an engagement portion provided at equal intervals over both ends thereof and the shoelace connected to one end of each shoelace, The shoelace body can be attached to the shoelace by inserting the shoelace body through the pair of right and left shoelace holes, looping it into an annular shape, and engaging and fixing the engaging portion to the engaging body. "Shoelaces and lace shoes provided with the same" (see Patent Document 4), which is characterized in that it has been made possible, are known techniques.

  However, the proposal of the “shoelace and the lace shoe provided with it” is that the binding body itself is large, the operability and the structure are complicated, and the place where the tip of the shoelace fits must always be monitored. There was a problem of having annoyance.

  The present applicant pays attention to various problems in the tightening means of the above-described lace shoes, and is a lightweight and inexpensive lace that tightens the lace shoes, and is easy to operate and has safety. Under the idea that it is impossible to provide lace shoes, we developed a lace strap that can tighten and release the upper part of the lace shoe with a single touch and a lace shoe provided with the same. And lace shoes equipped with it.
