Description

Detachable shoe heel

The present invention relates to a shoe heel having an easily removable replacement structure, and in particular, when replacing the shoe heel, the shoe heel can be quickly replaced with a new one easily and conveniently without a separate adhesive material or a work tool and a fastening element. The present invention relates to an easy-to-removable shoe heel that can improve the reliability and productability as well as increase the customer's desire to purchase the product by reducing the repair cost and eliminating the trouble of requesting the repairman.

Shoes commonly used, or shoes, are one of the shoes made of leather, which are worn on the feet of a person to protect their feet. They are made of various sizes and sizes using leather and synthetic rubber materials. In recent years, as the interest in the feet of the body has increased, shoes made of various functions and structures have been produced in the field of shoe manufacturing.

If the shoe is used for a long time, the repeatedly folded part of the body of the leather is damaged or the sole formed of the synthetic rubber is worn, and in particular, the heel of the shoe is worn faster than the front part. It is a situation to replace.

To replace the heel of the shoe, first remove the waste auxiliary heel attached to the lower part of the primary heel, and then smoothly polish the lower surface of the basic heel to which the waste auxiliary heel is attached, and then the mutually corresponding surface of the basic heel and the new secondary heel. After applying the adhesive to each of the appropriate time, and after a predetermined time, they are attached to each other and, if necessary, additionally fixed by using additional nails.

The auxiliary heel attached to the basic heel is cut by using a sharp tool or the like to cut the protruding outer circumference and polish the outer surface of the grinding machine to replace the shoe heel.

Therefore, the preliminary application, which has a structure that allows the wearer to directly replace the heels of such shoes, is published in Korean Utility Model Application Nos. 84-771 (1984.1.30) and 85-632 (1985.1.24). It is known.

Looking at the main configuration of the utility model applied before the domestic, respectively. First, the application number 84-771 ″ Disassembly-Assembled Shoe Heels ″ shown in FIG. 1 is briefly divided into a primary heel (1) and an auxiliary heel (2). The fitting hole (3) is formed, and the fitting projection (4) corresponding to the fitting hole (3) is placed in the upper surface portion of the auxiliary heel (2) and is configured to fit to the auxiliary heel (2).

Also, briefly look at the application No. 85-632 ″ Shoe heel device ″ shown in Figure 2 between the sole and the midsole with a reinforcing plate (3) formed with a nut (1) in the center and a nail hole (2) in the periphery Buried, and fix the heel (7) to the sole with nails nailed from the nail holes (2) of the reinforcement plate, and fix the disc-shaped auxiliary heel (9) to the disc bottom (7 ″) of the heel with nabon (10). The head 10 'of the nabon is located in the bottom recess 9 ″ of the auxiliary heel 9 and the shaft of the nabon 10 is inserted into the reinforcing plate 3 through the insertion holes 4', 7 'and 9'. It consists of a shoe heel device which is screwed onto the nut (1) on the top.

However, since the heel of the conventional shoe requires a certain skill and skill to replace it, it is difficult for the wearer to replace the shoe directly. Therefore, it is cumbersome and inconvenient because it requires a repair request to the nearest shoe repair shop. There was a problem that time is consumed and the outer surface of the repaired part is not neat and the appearance is deteriorated.

On the other hand, the above-described filing of the domestic utility model application No. 84-771, the prefabricated shoe heel is a plurality of fitting holes and decompression projections are formed in the primary heel and auxiliary heel of the shoe, respectively, the decompression hole and the decompression projections by mutual coupling Because it is fixed, the fastening fastening force is weak and frequent separation and breakage occurs during use, there is a significant drawback in use there was a problem that the productability and reliability of the product is reduced.

Another pre-applied Korean Utility Model Application No. 85-632, the shoe heel device is a separate reinforcement plate and bolts, nuts, etc., because a large number of fastening elements are used, the structure is relatively complicated, and the manufacturing process and cost is increased and auxiliary heel As a separate tool must be used for the replacement work, there is a drawback that the purchasing desire for the product is lowered due to the ease and convenience of replacement, and the fastening structure that is likely to be separated and detached due to loosening due to loose coupling elements. There were problems.

Accordingly, the present invention has been made to solve the fundamental problems of the prior art, the object of which is to easily and conveniently pull out the heel without a separate adhesive or fastening elements and work tools when replacing the heel of the shoe, and then a new heel It can be replaced and replaced by simply snapping it, and it is firmly fixed at the time of fastening and is formed to prevent separation during use. It reduces the repair cost and inconvenience and hassle caused by replacement of the heel of shoes. Increasing of course, as well as providing easy to remove shoe heel that can improve the reliability and productability.
