Polygonal tipped shoelace

Abstract

A polygonal tipped shoelace comprises at least a shoelace and a polygonal tip. Plastic films are first adhered to the two terminals of the shoelace, and are subsequently pressed by polygonal molds to form polygonal tips. The polygonal tips could provide various shapes of the shoelace to raise the delicacy and the uniqueness. The durability of the shoelace is also increased because there is a larger contacting area between the shoelace and the plastic film so that it is not easy for the tip to fall off.

Description

RELATED APPLICATIONS

The present application is based on, and claims priority from, Taiwan Application Serial Number 95203656, filed Mar. 06, 2006, the disclosure of which is hereby incorporated by reference herein in its entirety.

BACKGROUND

1. Field of Invention

The present invention relates generally to a shoelace, and more particularly to a polygonal tipped shoelace.

2. Description of Related Art

There are several different general shoelace tip designs depending on the need, for example, cylindrical tips attached around to plastic films, tips attached to the sleeve made from extruded metal, tips attached to the sleeve made from plastic and so on.

The method of attaching metal or plastic sleeves to the shoelace tips is more complex because to attach the sleeves to the shoelace tips requires more than at least two processes. Therefore, it is more expensive and less popular.

Attaching a cylinder wound by a plastic film to the shoelace tips is easier to produce and cheaper. Therefore, the most popular method is to attach the cylinders, with smaller diameters than the diameter of the shoelace, wound by the plastic film to the shoelace tips. However, these tips easily fall off when pulled or washed because no enough area and coupling strength of the cylinder structure of the shoelace are provided. Therefore, it is quite inconvenient.

Consumer demand nowadays emphasizes the importance of design and uniqueness of dress accessories. In order to enhance personal dress style and creativity, the shoelace's color is no longer simple color as usual. Fashionable, colorful shoelace styles with matching features are becoming more accepted. Therefore, valuable and attractive shoelace tip designs provide consumers with more choices and achieve the goal of being unique and decorative.

SUMMARY

It is therefore an objective of the present invention to provide a polygonal tipped shoelace which improves the failings of the traditional shoelace tips, like inflexible forms, and the lack of a unique sense or design.

It is another objective of the present invention to provide a polygonal tipped shoelace which improves the problem of easily falling off due to the small adherent strength between the shoelace and the tip.

According to the aforementioned objectives of the present invention, a polygonal tipped shoelace is provided. The terminal of the shoelace is a polygonal tip attached to a plastic film and pressed by a mold. In one embodiment of the present invention, the shoelace could be an elliptic cylinder, or a flat form cylinder. The polygonal tips are pressed by molds into desired shapes, so the terminal section of the polygonal tip is a polygon, like a triangle, a rhombus, a trapezoid, an astroid shape, an octagon, a dodecagon or some other appropriate shape.

Furthermore, pictures, like trademarks, could be printed on the polygonal tips. Also, fluorescent material, jewel like substances, or other materials and items that could improve the design of the tip could be smeared on the polygonal tips in order to boost the market competitiveness.

The polygonal tips could provide various shapes to increase the unique and delicacy. Moreover, it provides a larger contacting area between the shoelace and the plastic film, so the tip part wouldn't fall off easily and it would have increased durability.

It is to be understood that both the foregoing general description and the following detailed description are by examples and are intended to provide further explanation of the invention as claimed.

While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the figures, in which like reference numerals are carried forward.

Reference is made to FIG. 1, which illustrates a polygonal tipped shoelace of the preferred embodiment of the present invention. A polygonal tipped shoelace 100 includes a main body 110, a tipped terminal 120 located in each terminal of the main body 110, the tipped terminal 120 is covered with plastic film and pressed into specific shape by mold, and forms a polygonal tip 130.

In the preferred embodiment of the present invention, the main body 110 could be an elliptic cylinder or a flat form cylinder or an irregularly shaped shoelace. The polygonal tip 130 is pressed in the forms of specific shape by the mold, so the terminal section of the polygonal tip 130 could be a polygon, like a triangle, a rhombus, a trapezoid, an astroid shape, a hexagon, an octagon, a dodecagon or some other appropriate shape.

Compared to the general circular tipped shoelace, the polygonal structure of a polygonal tip could increase the contacting area between the plastic film and the tipped terminal 120 thus increasing the strength of the attachment. Mechanical friction and coupling force increased by the corners makes the plastic film difficultly to fall off thus increasing the durability of a polygonal tipped shoelace compared to a general circular tipped shoelace. Furthermore, polygonal tip shoelaces can be held more tightly making them easier and more convenient to use.

Reference is made to FIG. 2, which illustrates a triangle tipped section of the preferred embodiment of the present invention. A plastic film 210 is smeared with mucilage or an solvent, like the acetone, and attached to the two terminals of the shoelace; then it would be heated to make it softer, and at finally shaped into a triangle tipped shoelace after being pressing by the triangle mold. Therefore, the section would also be the shape of triangle.

Reference is made to FIG. 3, which illustrates a section of the pentagonal tip of the preferred embodiment of the present invention.
