Description

[Detailed Description of the Invention] Industrial Application Field The invention relates to shoelaces, particularly elastically deformable shoelaces.

BACKGROUND OF THE INVENTION Men's shoes are broadly classified into two types: slip-on shoes and strap-on shoes. The slip-on shoe has a structure in which a tongue provided on the instep of the shoe is joined to the side of the shoe with elastic fabric. Due to this structure, slip-on shoes can be easily put on or taken off without tying the laces, but they are not suitable for formal wear. In contrast, with lace-type shoes, the laces must be repeatedly tied and released, and this tedious operation may be undesirable to some users.

Problems that the invention attempts to solve For example, Utility Model Application No. 48-97150 or Utility Model Application No. 51
As shown in Japanese Patent No. -88442, stretchable shoelaces are known. However, these shoelaces do not have anti-slip treatment on the surface of the laces, so they tend to slip easily.
As a result, there was a problem with the shoelaces coming undone.

Therefore, the object of this invention is to solve the above-mentioned problems and provide a shoelace having an anti-slip surface and elasticity.

Means for Solving the Problems The elastic shoelace according to this invention consists of an elongated lace body and hardened ends formed at both ends of the lace body, and the lace body is elastic and non-tight when pulled. The string body is elastically deformed to a length 1.5 times or more longer than when it is pulled, and the string body has an elastic core and an outer skin surrounding the core, and a large number of small synthetic resin beads are attached to the surface of the braid constituting the outer skin. A protrusion is formed.

Function Since the shoelaces are stretched when the shoes are put on and taken off, the shoes with elastic shoelaces according to this invention can be used in the same way as slip-on shoes. In addition, the numerous small protrusions made of synthetic resin formed on the surface of the braid that constitutes the outer skin have an anti-slip effect, and the shoelaces will not come undone after being tied.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings. As shown in the drawings, the elastic shoelace 1 according to the invention consists of an elongated lace body 2 and hardened end portions 5 formed at both ends of the lace body 2. The string body 2 is composed of a cloth outer sheath 3 and a rubber elastic core 4 surrounded by the outer sheath 3. The outer skin 3 is a round or flat braid braided into a tubular shape, and its surface is treated to prevent slipping. The anti-slip finish is achieved by forming a large number of small protrusions made of synthetic resin on the surface of the braid. The elastic core 4 can be made of various synthetic rubbers such as polychloroprene.

Hardened end portions 5 are formed at both ends of the string main body 2, and these end portions 5 are formed by hardening the ends of the string main body 2 with synthetic resin, adhesive, etc., or by hardening the ends of the string main body 2 with a central hole of a hard cylindrical collar. It can be formed by attaching and fixing the end of the string main body 2 to the string body 2.

The lace main body 2 of the shoelace according to this invention has elasticity,
When tensioned, the length is more than 1.5 times that of non-tensioned state.
Preferably, it is elastically deformed to twice or more the length.

In order to manufacture the shoelace 1 having elasticity according to this invention, first, a synthetic resin adhesive such as epoxy is partially applied to the surface of the tubular outer skin 3 made of braided cord, and the adhesive is cured to form the outer skin. A large number of small protrusions are formed on the surface of 3. Next, the string main body 2 is constructed by inserting the elastic core 4 into the hollow part of the tubular outer skin 3 in which a large number of small protrusions are formed. At this time, the elastic core 4 is formed to be slightly longer than the outer skin 3.
Both ends of the outer skin 3 protrude slightly from both ends of the outer skin 3. Finally, both ends of the outer skin 3 and the protruding portion of the elastic core 4 are surrounded with a synthetic resin adhesive or the like and hardened to form a hardened end 5. As a result, both ends of the lace main body 2 are fixed, and the shoelace 1 having elasticity is completed.

Effects of the invention As mentioned above, in the elastic shoelace of this invention, many small protrusions made of synthetic resin are formed on the surface of the braid that constitutes the outer skin surrounding the core, so the surface has anti-slip properties. It has the advantage of being retained and not unraveling after the shoelace is tied. Therefore, the shoelace according to this invention does not cause the inconvenience of having to retie the shoelace that has come undone many times. In addition, this shoelace elastically deforms to 1.5 times the length compared to when it is not tensioned, so when used in lace-type shoes, it is easy to wear without having to perform the cumbersome lace binding and release operations like slip-on shoes. You can take it off or take it off. In addition, since it can be used for strap-type shoes, it is also suitable for formal wear, and is convenient for practical use.
