Description

An auxiliary heel for shoes

This invention is directed to the heel of a footwear. Particularly, the present invention relates to an auxiliary heel for footwear which can be attached to and detached from the heel of various kinds of footwear such as shoes and sneakers (hereinafter referred to as "shoes") and which is structurally simple but has excellent product performance.

Conventional shoe heels require that the user wear shoe so that the heel of the shoe worn out after a certain period of durability has expired. Generally, only a part of the heel of a shoe is worn, but a shoe wearer usually goes through the entire heel. However, this was uneconomical. This is because the price of the heel is too high compared to the value of a pair of shoes. Therefore, there is a need for a technique capable of solving these problems.

In order to solve these problems, there has been a demand for development of a supplementary heel that can be used by replacing a part of the heel of another footwear by a detachable method as well as shoes. Some techniques have been developed but the structure of the heel portion of the shoe is complicated, There was a problem that the unit price would rise, which was ineffective.

In this atmosphere, recently, a technique of attaching and using an auxiliary heel having a protruding portion formed in the shoe heel has been developed. However, in this case, there was an inconvenience that the projection was machined. Therefore, it has been necessary to introduce a more technologically improved technique capable of solving these problems, and the technology of the present invention has emerged under these circumstances.

One of the prior arts in this field is patented patent No. 10-1000-722 (Registered on Dec. 7, 2010) "Young shoe has a backhoe with detachable detachable heel". However, this technique is problematic in that it is uneconomical because of the complicated configuration of the auxiliary backhoe, and it is not easy for an individual to easily remove and remove, and it will be similar to the price of a general heel.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an auxiliary means for a sole of a simple structure that can be easily attached to and detached from a corresponding portion of a foot to prevent wear of a specific portion of the heel.

Other objects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

The auxiliary heels 30 are inserted into the respective grooves 70 and attached to the heel 20 when the auxiliary heels 30 are placed on the respective grooves 70 of the heel 20 and pressed, A protruding portion A of the upper auxiliary heel 30 has a structure in which a part of the spherical portion is cut out in a horizontal direction and the size and shape of the groove 70 are formed in the upper auxiliary Corresponds to the size and shape of the inserted portion B of the backsheet 30 and the upper projected portion A and the inserted portion B are integrated.

<Operation Principle>

Fig. 1 shows an embodiment of a secondary heel for a shoe sole according to the present invention. A rear sheath 20 is attached to the rear side of the shoe bottom surface 10 to which the present invention is applicable. The auxiliary heel 30 for the heel 20 according to the present invention is applicable to most of the conventional shoes 100. It can be applied not only to shoes but also to various kinds of shoes such as sneakers and boots. However, in the present invention, all the shoes to which the auxiliary heel 30 of the present invention is applicable are collectively referred to as shoes 100 for convenience. For example, shoes, athletic shoes, hiking, workings, and the like are included in the shoes 100 of the present invention. In addition, the invention can be applied to most footwear where the heel 20 is not very low.

In Fig. 1, the auxiliary heel 30 is composed of an upper portion and a lower portion. The upper section consists of a vertical line connecting the arc and arc ends, and the lower part of the upper section is a horizontal section. The lower part forms the lower part, that is, the conical column when the upper surface of the horn is cut horizontally. The upper and lower portions are integrally formed.

The upper portion may be caught by the periphery of the groove 70 so that the upper portion may protrude (see Fig. 7), or a portion of the upper portion may be inserted into the groove as shown in Fig. The shape of the groove 70 is shown in the second figure of FIGS. However, it is needless to say that the grooves 70 can be formed in different shapes. For example, a cylindrical groove 70 is also possible.

 And the diameter of the lower portion of the lower portion is slightly larger than or equal to the entrance of the groove 70. [ This is because when the auxiliary heel 30 is placed on the groove 70 and the user pushes the auxiliary heel 30 with his or her thumb or the like, the elasticity of the heel 20 causes the groove opening slightly to allow the auxiliary heel 30 to enter into the groove 70, Therefore, the auxiliary heel is firmly attached to the groove, so that the effect of not being easily released is obtained.

Fig. 2 is an exemplary view in which the auxiliary heel 30 of Fig. 1 is attached to the heel 20; The auxiliary heel 30 is protruded more than the heel 20 to prevent the heel 20 from being worn out.
