Description

[Technical field]

[0001] The present invention relates to a protective cap for shoe laces. [Background technology]

[0002] There is known an ornament for the head of a shoelace (corresponding to the "protective cap for shoelace" of the present invention) that is attached to the cell tip at the end of the shoelace to protect the cell tip and also to improve fashionability (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Specification of Utility Model Registration No. 3108209 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the ornament for shoelace heads described in Patent Document 1 is made of metal, an aluminum alloy that has been colored by plating, and there is a problem that the plating peels off after long periods of use, damaging the surface of the shoe.

[0005] The present invention was devised to solve the problems in the prior art described above, and its object is to create a protective cap for shoelaces that has excellent abrasion resistance and prevents scratches on the surface of the shoe. [Means for solving the problem]

[0006] Among the means for solving the above problems, the first means of the present invention is: A shoelace protective cap that is attached to a cell tip provided at the end of a shoelace, It has an elongated cylindrical tube portion, a hemispherical closing end that closes one end of the tube portion, an open end formed at the other end of the tube portion, and a hollow portion provided inside the tube portion into which the cell chip is inserted, and is characterized by being formed of an elastic body. In the above first means, since the protective cap is formed of an elastic body, even if the greatly swaying protective cap abuts violently against the shoe during the user's walking, it is possible to prevent the surface of the shoe from being damaged over a long period of use.

[0007] The second means of the present invention is the above first means with the additional means that the elastic body is TPU (thermoplastic polyurethane). With the above means, in addition to elasticity, a protective cap excellent in abrasion resistance, flexibility, oil resistance (chemical resistance), low temperature resistance, and processability can be obtained.

[0008] The third means of the present invention is the above first or second means with the additional means that when the length dimension of the cell chip is L and the outer diameter dimension is φ, the length dimension a of the tube portion is in the range of L ≦ a < L + 3 mm, and the inner diameter dimension b is in the range of φ ≦ b < φ + 1 mm. With the above means, handling and attachment to the cell chip can be made easy.

[0009] The fourth means of the present invention is the above first or second means with the additional means that the length dimension a of the tube portion is in the range of 14 mm ≦ a ≦ 25 mm, the inner diameter dimension b of the tube portion is in the range of 2.5 mm ≦ b ≦ 3.5 mm, and the outer diameter dimension c of the tube portion is in the range of 4.2 mm ≦ b ≦ 5.4 mm. With the above means, in addition to facilitating handling and attachment to the cell chip, insertion into the grommet hole can be made easy. The fifth means of the present invention is the above first or second means with the additional means that characters, figures, symbols, colors, or combinations thereof, or comic characters are arranged on the surface of the tube portion. The above means can improve fashionability. Effect of the Invention

[0010] The present invention can prevent scratches on the shoe surface and improve the fashionability of the shoes. [Brief description of the drawings]

[0011] [Figure 1] 1 is a perspective view showing a shoelace protection cap according to the present invention; FIG. [Diagram 2] FIG. 2 is a cross-sectional view of a protective cap for shoelaces. [Diagram 3] FIG. 1 is a diagram showing an example of a shoe fitted with a shoelace protection cap. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] FIG. 1 is a perspective view showing a shoelace protection cap according to the present invention, and FIG. 2 is a cross-sectional view of the shoelace protection cap. As shown in the embodiment of Figure 1, the shoelace protective cap 1 of the present invention (hereinafter referred to as the "protective cap 1") is integrally formed with an elongated tubular portion 2, a hemispherical closed end 3 closing one end of the elongated tubular portion 2, an open end 4 formed as an opening at the other end of the elongated tubular portion 2, and a hollow portion 5 extending from the open end 4 toward the closed end 3 inside the elongated tubular portion 2.

[0014] The protective cap 1 is made of an elastic body. The material from which the protective cap 1 is made is preferably one that has elasticity as well as wear resistance, flexibility, oil resistance (chemical resistance), low temperature resistance, and processability, and is preferably, for example, TPU (thermoplastic polyurethane).

[0015] When the protective cap 1 is used for a cell chip of normal size, the length dimension a of the long tube portion 2 is preferably in the range of 14 mm to 25 mm (14 mm≦a≦25 mm) because it is difficult to handle when the length dimension a of the long tube portion 2 is less than 14 mm or exceeds 25 mm. Furthermore, the inner diameter dimension b of the long tube portion 2 (also the diameter of the hollow portion 5) is preferably in the range of 2.5 mm to 3.5 mm (2.5 mm≦b≦3.5 mm) because it is difficult to insert the cell chip when it is less than 2.5 mm, and it is easy to fall off after installation when it exceeds 3.5 mm. Furthermore, the outer diameter dimension c of the long tube portion 2 is preferably in the range of 4.2 mm to 5.4 mm (4.2 mm≦b≦5.4 mm) because it is difficult to handle when it is 4.2 mm or less, and it is difficult to pass the eyelet through when it exceeds 5.4 mm.

[0016] The color of the protective cap 1 is not particularly limited and may be various colors, may be a single color, or may be a combination of multiple colors. Furthermore, letters, figures, symbols, colors, or combinations of these, or cartoon characters may be arranged on the surface of the long tube portion 2, and it is preferable to use these to enhance the fashionability.

[0017] The protective cap 1 having the above-mentioned structure is used in a state where it is attached to the end of a shoelace. Fig. 3 is a diagram showing an example of a shoe fitted with a shoelace protective cap. Note that Fig. 3 shows a case in which the protective cap 1 is fitted to only one end of the shoelace 20, but it goes without saying that it may be fitted to both ends.

[0018] 3, the protective cap 1 is attached to a cell chip 21 provided at the end of a shoelace 20 that is passed through a plurality of eyelet holes 11 of a shoe 10. More specifically, the cell chip 21 is inserted into the hollow portion 5 from the open end 4 of the protective cap 1, thereby attaching the protective cap 1 so as to cover the outer peripheral surface of the cell chip 21. The protective cap 1 may be attached to the shoelace 20 after the shoelace 20 has been threaded through the multiple eyelet holes 11, or may be attached to the shoelace 20 after it has been tied. If the outer diameter of the protective cap 1 is smaller than the inner diameter of the eyelet holes 11 and can pass through, the protective cap 1 may be attached to the cell chip 21 first, and then the shoelace 20 may be threaded through the eyelet holes 11 and tied.

[0019] The protective cap 1 is formed from a material that is elastic and has excellent abrasion resistance, so that even if the protective cap 1 swings wildly while the user is walking and hits the shoe violently, it is possible to prevent the surface of the shoe from being damaged over a long period of use.

[0020] Although the configuration and effects of the present invention have been described above based on the embodiments, the present invention is not limited to the above embodiments.

[0021] For example, in the above embodiment, the size of the protective cap 1 was described as being used for a normal-sized cell tip, but the size of the protective cap 1 depends on the size of the cell tip. For this reason, if the length dimension of the cell tip attached to the end of the shoelace is L and the outer diameter dimension is φ, then the length a of the long tubular portion 2 is preferably in the range of L≦a≦L+3 mm, and the inner diameter dimension b of the long tubular portion 2 is preferably in the range of φ≦b≦φ+1 mm.

[0022] In the above embodiment, the long tube portion 2 is in the shape of a long and thin cylinder, but the long tube portion 2 may be in the shape of a long and thin rectangular tube.

[0023] Furthermore, in the above embodiment, in order to prevent the protective cap 1 from coming off while walking, a locking means such as a protrusion for locking the cell chip 21 may be provided around the inner peripheral surface of the hollow portion 5 on the side of the open end 4 .
