Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to shoelaces, and more particularly to shoelaces having elasticity and coiled elasticity.

[0002]

[Prior art]

 In general, the function of shoelaces used in athletic shoes and leisure shoes sold at sporting goods stores and supermarkets, etc., is to prevent the shoes from loosening while walking and to change the color of the shoelaces. The change is to improve the visual effect of the appearance of the shoe. FIG. 1 is a perspective view of a state in which a conventional shoelace is applied to athletic shoes or the like. The shoelace B passed through the strap hole C of the shoe body A is mainly made of a textile string or a leather string. In use, the shoelace B is passed through the strap hole C of the shoe main body A, and then the length of the shoelace B is set so that the shoelace B is too long and does not trip over during walking. Both ends of the shoelace B are tied to each other while adjusting the length.

[0003]

[Problems to be solved by the invention]

 The conventional shoelace B as shown in FIG. 1 can fulfill the purpose of tying the shoelace B when wearing the shoe and adjusting the length of the shoelace B so that the shoelace B does not fall down. There are still some disadvantages listed below. Because shoelace B is made of woven or leather straps, its elasticity is limited, and it can be loosened or over-tightened while walking with shoelace B connected to the foot. A sense of incongruity occurs. When tying shoelace B after passing it through string hole C, the length of the remaining shoelace must be adjusted so that it is not too long. When tying shoelaces B, it is a common way to tie shoelaces B with a bow. However, it is quite annoying to tie a bow when putting on shoes, to break a bow when taking off shoes, and to repeat such actions one by one. Furthermore, many people are not good at tying shoelaces B to bows, and the shoelaces B tied by such people are loosened and loosened during walking, and their feet are taken off by the shoelaces B and fall. There is a risk of rusting.

[0004] The present invention was devised in view of the above-mentioned circumstances, and the present inventor has devised ingenuity and research based on his extensive experience gained in designing and manufacturing shoes for many years. Well, through various tests, we improved the problems of existing shoelaces and developed the stretchable shoelaces of this invention.

The main object of the present invention is to attach a shoelace to an inner material having a desired length and an outer material covering the inner material, and to a part of a longitudinal gap between the inner material and the outer material. And an elastic body having a higher elasticity and a coil-like elasticity than the inner material, so that the shoelace is held in a coil spring shape and the coil spring shape is maintained. The purpose of the present invention is to provide a shoelace that can be restored to its original shape after the shoelace has been pulled and stretched.

Another object of the present invention is to provide a shoelace in which both ends of the shoelace are wound in a coil spring shape and do not need to be tied. Furthermore, when the shoelace is not in use, the shoelace is always in a contracted state wound in a coil spring shape, and the shoelace is novel and original in appearance and easy to pack and store. The purpose is to provide.

[0007]

[Means for Solving the Problems]

 The invention according to claim 1 is characterized in that the shoelace is attached to a part of a longitudinal gap between the inner member having a desired length and an outer member covering the inner member, and the inner member and the outer member, and An elastic body having a higher elasticity and a coil-like elasticity than the inner material, and the shoelace is wound into a coil spring shape by an elastic force acting on one side of the shoelace by the elastic body. It is characterized in that the coil spring-shaped shoelace can be restored to its original shape after being stretched by being stretched while being held in a state.

According to a second aspect of the present invention, in the stretchable shoelace according to the first aspect, the inner member is formed by bundling a plurality of elongated rubber cords, and the outer member has flexibility made of urethane resin thread. It is characterized by having a woven cloth.

A third aspect of the present invention provides the stretchable shoelace according to the first aspect, in which the number of the elastic bodies attached between the inner member and the outer member is increased to a plurality of elastic members, and the elasticity and the elasticity of the shoelace are increased. It is characterized by enhanced coiled elasticity.

[0010]

[Embodiment of the invention]

 Hereinafter, an embodiment of the stretchable shoelace of the present invention will be described with reference to the drawings. FIG. 2 is a perspective view of the stretchable shoelace according to the present invention, FIG. 3 is an enlarged longitudinal sectional view of the stretchable shoelace according to the present invention, and FIG. 4 is a stretchable shoelace according to the present invention. It is a perspective view which shows the use condition of.

As shown in FIG. 3, the shoelace 10 of the present invention shown in FIG. 2 is formed by bundling a plurality of rubber straps so that the entire shoelace 10 retains sufficient elasticity and coiled elasticity. And an outer member 12 knitted with a urethane resin thread that covers the outside of the inner member 11, and a part of a gap generated between the inner member 11 and the outer member 12. An elastic body 13 made of rubber or synthetic rubber or the like manufactured to have elasticity and coil-like elasticity higher than the elasticity of the inner material 11 along the longitudinal direction of the shoelace 10 is straightened. When the shoelace 10 is mounted in an extended state and is not used due to the mounting of the elastic body 13, the shoelace 10 is spirally rounded inward and rounded, and the overall structure becomes like a coil spring. .

Therefore, when the shoelace 10 is used, the two ends 10 a and 10 b of the shoelace 10 can be stretched against elasticity so as to be straightened, and can be attached to the shoe 20 through the shoelace 10 through the strap hole 21 of the shoe 20. Both ends 10a and 10b of the shoelace 10 protruding beyond the last cord hole 21 forming the knot are released from the original coil spring shape by the elastic stretching force of the elastic body 13 by eliminating the stretching force. Restores to a rolled shape.

FIG. 4 is a perspective view showing a use state in which the shoelace 10 of the present invention is passed through a plurality of string holes 21 of the shoe 20. When the shoelace 10 of the present invention is used, first, After passing both ends 10a and 10b of the shoelace 10 through the plurality of string holes 21, respectively, the shoelace 10 is pulled to adjust the shoelace 10 so that it fits perfectly with one's foot.

The ends 10a and 10b remaining outside the shoelace 10 after the adjustment is completed are automatically restored to a coil spring shape by releasing the shoelace 10, and usually a knot is formed. Because it stops at the final string holes 21a, 21a, it is not necessary to tie both ends of the shoelace 10 together, and the shoelace 10 is unraveled or too long, and the foot is taken off and falls down. Such accidents can be prevented.

In addition, in the shoelace 10 of the present invention, it is not necessary to tie or release both end portions of the shoelace 10 each time the shoe 20 is worn or taken off, so that the convenience of wearing the shoe 20 is improved. At the same time, the shoelace 10 expands and contracts according to the temperature of the foot, such that the shoelace 10 expands when the temperature of the foot is high, and contracts when the temperature of the foot is low. Therefore, the comfort when wearing the shoes 20 can be increased.

Furthermore, the shoelace 10 may be manufactured by increasing the number of the elastic members 13 in a manufacturing stage of the shoelace 10 main body in order to increase elastic elasticity according to needs. That is, by arranging a plurality of elastic bodies 13 on the same side in the gap between the inner member 11 and the outer member 12, the elasticity of the shoelace 10 is further enhanced, and the shoelace 10 is further tightened. And it comes to twist around. By increasing or decreasing the number of the elastic bodies 13 in this manner, the stretching strength of the shoelace 10 can be selected according to the needs of the person wearing the shoes 20.

The shoelace 10 described above is merely an example of the present invention and does not limit the present invention. Any modifications or changes arising from this invention are intended to be within the scope of the claims.

[0018]

[Effect of the invention]

 As described above, the stretchable shoelace of the present invention has the following effects. The shoelace was wound into a coil spring shape by an elastic body having higher elasticity and coil-like elasticity than the inner material in an elongated shoelace composed of an inner material and an outer material covering the inner material. Since the shoelaces are held in a state, the shoelaces have a coil spring shape in which the shoelaces are spirally wound around the clock, so that it is convenient to pack and store the shoelaces, The strings themselves can also have a novel and original appearance. Due to the elastic elasticity of the shoelace, the distance between the respective shoelace holes through the shoelace also takes on elasticity. Even in such a case, the tightening of the shoelaces increases with an increase in the temperature of the foot, and the width of the shoe is widened, so that a feeling of oppression is not applied to the foot. Unless force is applied by hand, the shoelace has a wound shape like a coil spring like a coil spring, so after passing the shoelace through the shoelace hole and pulling it according to the shape of the foot, If you release your hand at the final lace hole where the knot is tied, the free ends of both ends of the shoelace are entangled with twirl and restored to their original shape and stop at the string hole, so there is no need to tie shoelaces, It is particularly suitable for those who have difficulty tying shoelaces, such as the elderly and the elderly. Note that the shoelaces may be arbitrarily combined as desired if desired.
