Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reinforcing toecap of a shoe having improved strength.

[0002]

[Prior Art]

 In shoes, especially safety shoes, a reinforcing toe core is built in the toe part of the shoe for the purpose of protecting the toes of the user and further maintaining the shape retention property of the shoe. Here, the reinforcing toe core that has been used heretofore consists of a steel material or a plastic material having a thickness of about 1 to 3 mm and covering the front end face, the upper face, and the left and right side faces, and at least the lower face is open. It was formed into a shape (see FIG. 2). In addition, in some of the reinforcing toecaps, the brim portion for mounting was formed by bending the edge portion in contact with the lower surface inward with a width of several mm in a horizontal shape. However, most of the lower surface was formed in an opening shape.

[0003]

[Problems to be solved by the device]

 At present, one of the important requirements for working safety shoes is the demand for weight reduction of shoes. However, in most conventional safety shoes, a toecap made of steel material is incorporated in the toe, which hinders weight reduction (the specific gravity of steel material is very heavy at 7.8 to 7.9). As a solution to this weight reduction, it is considered to use a plastic toecap with a small specific gravity.However, the plastic toecap has a steel material tip that is resistant to dents and cracks caused by falling objects and has a compression resistance. There was a weakness that it was a fraction of the core. Of course, attempts have been made to adopt a high-performance plastic toecap to improve performance and to improve the strength by mixing various fibers into the material, but to the same level as steel materials. The strength could not be increased.

As a result, the next consideration is to increase the thickness of the plastic material. However, the plastic material has the same strength as the steel material toe core having a thickness of 1.1 to 1.3 mm. However, in reality, the thickness must be about 3 to 5 mm. However, if a plastic toecap with such a thick dimension is used, the surface of the toe part of the shoe containing the toecap may bulge extremely, or the upper may be suspended in the last during actual product processing. There were problems such as difficulty. The present invention is intended to provide a toe for reinforcing a shoe that can increase the strength of the toe without increasing the thickness even if the toe is made of plastic.

[0005]

[Means for Solving the Problems]

 Therefore, in the present invention, in the reinforcing toe built into the toe of the shoe, the toe is formed of a hard material having a thickness of 1.5 to 3 mm, and the toe is formed only at the rear end face of the opening. The toe for reinforcing the shoe, which is formed in the shape of a tubular cap, is a means for solving the problem.

[0006]

[Action]

 By adopting the structure of the present invention, even if a hard plastic material is adopted, the lower surface of the toe core will be pushed to the left and right side by the pressing force as in the past, even if a hard plastic material is adopted. It is no longer opened and the entire toe box is crushed.

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of the present invention seen from an obliquely upper rear portion, and FIG. 2 is a perspective view of the conventional example. The present invention is preferably formed of a hard plastic material, but other materials can be used as long as they have the same or higher strength. The toecap body A has a tubular cap shape that is obtained by cutting only the toes of the shoe, and the upper surface 1, the left and right side surfaces 2, the front end surface 3 and the lower surface 4 are all made of a continuous material to be integrally finished. Has been. Since it is necessary to insert the tip of the toe, the rear end surface 5 is naturally finished in an open shape. In FIG. 2, reference numeral 6 is a collar portion.

In the present invention, since the whole is formed with a thickness of 1.5 to 3 mm, the toecap becomes excessively thick and the toes of the shoe are extremely inflated, or the upper is the last when processing the product. It does not cause any problems such as making it difficult to hang, and the required strength is sufficiently secured. If the thickness of the toe core body is smaller than 1.5 mm, there is a problem in strength. On the other hand, if it exceeds 3 mm, it becomes too thick and difficult to use. For this reason, the safety shoes incorporating the toecap of the present invention have an upper surface 1 and left and right side surfaces 2 when an impact force (a numerical value within the range calculated in consideration of the safety factor in advance) is applied to the upper surface of the toe. , The front end surface 3 and the lower surface 4 have a continuous cylindrical cap shape, and since there is no opening on any of these surfaces, a part of the opening is spread by pressing force and the shape of the toe of the shoe is There is no worry that the will change. Furthermore, it is possible to form ventilation holes in appropriate places on the entire toecap to the extent that strength is not impaired, and in this case, the comfort of the shoe is improved.

[0009]

[Effect of the device]

 Therefore, according to the present invention, since the toecap can be changed from a steel product to a hard plastic product, the weight of the shoe can be reduced, and even in this case, the strength of the toecap is not deteriorated. Has the excellent effect that the security protection of is perfect.
