Slip-proof shoelace

Abstract

A slip-proof shoelace being characterized in that: a slip-proof member with a larger coefficient of friction (such as made of silicone, rubber or chemical plastic weaving fiber) is provided on a suitable length extending from each of two ends toward the other end of the shoelace. The slip-proof member can be an elastic sleeve with a smooth surface or a plurality of annular ribs, helical ribs or granules, extending from an end toward the other end of the shoelace, so that the shoelace forms an engaging action at the tying up area, and by the feature of having a larger coefficient of friction, the shoelace can be prevented from loosening and dropping.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a member for tying up a shoe.

2. Description of the Prior Art

Conventional shoelaces for tying up shoes generally are made of cotton, nylon, chemical plastic weaving fiber etc., the two ends of a shoelace are combined each with a leading portion which is harder and diametrically smaller than the main body of the shoelace. By guiding of the leading portions both with smaller diameters, the shoelace can be conveniently extended through shoelace holes on the shoe, and then the shoelace can be tied up on the shoe.

In wearing shoes, people often feel that shoelaces are subjected to loosening. To look into the reason of this, it is found that this is because that the coefficient of friction of the shoelaces is lower, especially on those shoelaces having smooth circular or flat sections and made of plastic, the shoelaces thereby are more subjected to loosening once they are not tightly tied up. However if the shoelaces are overly tied up, those wearing the shoes will feel uncomfortable.

SUMMARY OF THE INVENTION

The main objective of the present invention is to solve the defect that conventional shoelaces are subjected to loosening during exercising.

In view of this, the primary technical measure of the present invention is to provide a slip-proof member with a larger coefficient of friction (such as made of silicone, rubber or plastic on a suitable length extending from each of two ends toward the other end of a shoelace, in order that when the shoelaces are tied up, the shoelaces can be prevented from loosening by providing the member which has relieved parts and has a large coefficient of friction.

The slip-proof member of the present invention can be designed according to the idea of the designer to be an elastic sleeve with a smooth surface or a plurality of annular ribs, helical ribs or granules, extending from an end toward the other end of a shoelace, so that the shoelace has a function of slip proofing after being tied up to a shoe.

In comparison with a conventional shoelaces, in addition to having the features of easiness for threading and tying up as of the conventional shoelace, the present invention further has the effect of loosening proofing, so that the present invention is practicable and improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring firstly to FIG. 1, a preferred embodiment of the present invention is to make the main body of a shoelace 1 using any suitable material, e.g., using normally used cotton, nylon or chemical plastic weaving fiber; and the main body of the shoelace 1 is provided with a slip-proof member 2 with larger a coefficient of friction on a suitable length extending from the end rearwards of the shoelace 1, the slip-proof member 2 can be made of silicone, rubber or chemical plastic weaving fiber etc. with a larger coefficient of friction.

The slip-proof member 2 provided on the shoelace of the present invention can have multiple embodiments of practicing structurally, among them the first embodiment of the slip-proof member 2 is shown in FIG. 1, the main body of the shoelace 1 is provided with a plurality of annular ribs 21 extending from an end toward the other end of the shoelace 1 for a suitable length (as shown in FIG. 1). The end of the shoelace 1 still is provided with a leading portion 11 as is the case of a conventional shoelace for the convenience of threading through a plurality of holes (as shown in FIG. 2). With the structure of shoelace, after being tied up of the shoelace 1, the slip-proof member 2 having a larger diameter than the main body of the shoelace 1 forms an engaging action at the tying up area, and by the feature of having a larger coefficient of friction, the shoelace 1 after tying up is not subjected to loosening and dropping.

FIG. 3 shows the second embodiment of shoelace of the present invention, two slip-proof members 2 provided on the two ends of the shoelace 1 are elastic sleeves 22 with smooth surfaces, the elastic sleeves 22 are bound on the ends of the shoelace 1 by elastic binding force. Similarly, the ends of the shoelace 1 also are still provided each with a leading portion 11 for the convenience of threading through a plurality of holes. After being tied up of the shoelace, the slip-proof member 2 having a larger diameter than the main body of the shoelace 1 forms an engaging action at the tying up area too, and by the feature of having a larger coefficient of friction, the shoelace 1 after tying up is not subjected to loosening and dropping.

FIG. 4 shows the third embodiment of shoelace of the present invention, the main body of a shoelace 1 is provided with a plurality of helical ribs 23 extending from an end toward the other end of the shoelace 1 for a suitable length, and the ends of the shoelace 1 also are still provided each with a leading portion 11 for the convenience of threading through a plurality of holes.

FIG. 5 shows the fourth embodiment of shoelace of the present invention, the main body of a shoelace 1 is provided with a plurality of granules 24 extending from an end toward the other end of the shoelace 1 for a suitable length, and the ends of the shoelace 1 also are still provided each with a leading portion 11 for the convenience of threading through a plurality of holes.

The embodiments as above mentioned are only for illustrating the present invention, it will be apparent to those skilled in this art that various equivalent modifications or changes according to the idea of and without departing from the spirit of this invention shall also fall within the scope of the appended claims.
