Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a lace for athletic shoes such as skating shoes.

Technical background of the invention and its problems Traditionally, webbing straps made mainly of cotton thread have been widely used for laces for skate shoes.

Strings made mainly of cotton thread are unlikely to come undone, but in shoes that are subject to strong force, such as ice skating shoes, they can break quickly and cause an accident when the laces break during exercise. Ta.

In addition, the water impregnated in the shoelaces sometimes freezes, making it difficult to untie the knots.

Furthermore, webbing strings made mainly of nylon are more durable than strings made of cotton thread, and are less resistant to moisture and less likely to freeze, but they are slippery and knots tend to unravel, so they are faster. In the case of skating, etc., there are drawbacks that can cause particularly serious accidents.

Purpose of the invention The present invention was made in order to eliminate the above-mentioned drawbacks, and its purpose is to provide an exercise shoelace that maintains the durability of the shoelace and whose knots do not easily come undone. be.

Summary of the invention The structure of the invention consists of threads made of crimped stretchable synthetic resin fibers and threads made of non-stretchable synthetic resin fibers arranged alternately in parallel. a second yarn group in which yarns formed by converging crimped stretchable synthetic resin fibers and yarns converging non-stretchable synthetic resin fibers are alternately arranged in parallel; The first thread group and the second thread group are knitted in a diagonal manner, and are durable, and there is no risk of the knot coming undone due to the unevenness formed on the surface of the shoelace. There is no such thing.

Examples of ideas Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

1 is a single string body, in which a first thread group 2 and a second thread group 3 are knitted diagonally intersecting each other in a bag weave.

The first yarn group 2 and the second yarn group 3 are yarns 4 and 5 made of crimped synthetic resin fibers such as nylon having elasticity, and yarns 4 and 5 made of synthetic resin fibers such as nylon that do not have elasticity. The convergent threads 6 and 7 are arranged alternately in parallel.

Note that the number of fibers in yarns 6 and 7 formed by converging synthetic resin fibers that do not have elasticity is greater than the number of fibers in yarns 4 and 5 formed by converging synthetic resin fibers having elasticity. ing.

Therefore, the string body 1 which has been woven into a hollow shape 9 is further processed into a band string shape by compression processing or the like.

An unraveling stopper 8 is attached to both ends of the string body 1.

In this way, the knitted string body 1 is formed diagonally by threads 4 and 5 made of crimped stretchable fibers and threads 6 and 7 made of compressed non-stretchable fibers. It is formed in a linear shape and has an uneven surface.

This string body 1 has some elasticity due to the threads 4 and 5 made of crimped elastic fibers, and when the string body 1 is tied, the diagonal uneven portions engage with each other. High tension prevents knots from unraveling.

This is due to the diagonal braiding, so when the string body 1 is pulled strongly in both directions, the threads 4 and 5, which are made up of elastic fibers, try to contract, which applies force in the width direction, making the knot of the string tighter. It is maintained in the same state.

The string body 1 also includes a thread 4 formed by converging synthetic resin fibers. 5. 6. 7, it has durability without being cut by rubbing.

In addition, by making the threads 4 and 5 formed by converging the crimped synthetic resin fibers having elasticity and the threads 6 and 7 formed by converging synthetic resin fibers having no elasticity into different colors,
Distinctiveness can also be given.

Further, threads 4 and 5 made of the synthetic resin fibers converged. 6.
7 may contain cotton.

Effects of the invention According to the invention, the string body is made of synthetic resin fibers such as nylon braided with convergent threads, so it is durable, less likely to be impregnated with moisture, and cannot be frozen and untied. It's nothing.

Moreover, since the threads made of crimped stretchable fibers and the threads made of non-stretchable fibers are alternately arranged and intertwined diagonally, the uneven parts are formed diagonally. The concave and convex portions engage with each other to create a strong connection, increasing the tightening force, ensuring the durability and safety of the shoe, and making it particularly suitable for skating shoes. It is something that exists.
