Description

Male and female combined ornaments and method for manufacturing the same {Combination type ornamentand and methods for manufacturing a ornamentand}

The present invention relates to a male and female coupling apparatus, and more particularly, male and female coupling apparatus that can be easily and easily combined with each other, and can maintain the bonding state more stably and firmly, and its manufacture. It is about a method.

Generally, various fashion goods such as handbags, wallets, bags, belts, hats, new items, shoes, and clothing are displayed with trademarks, logos, and emblems, and they are designed to enhance the merchandise of the products by producing luxurious decorative effects and beautiful appearance. Ornaments of various shapes are attached for the purpose of connecting members such as bag straps, hooks and handles.

Here, the method of attaching and fixing such ornaments to various skin-attached objects, including bags, is a method of directly adhering with an adhesive and a hole in the skin-attached object and inserting male and female ornaments into the holes in opposite directions, respectively. There is a physical coupling method of fastening by screwing in a state or pressing by pressing deformation.

However, the method of directly bonding with the adhesive has a problem in that the adhesive strength is weakened easily after a certain time due to the external force is applied to the decoration or the constraints or washing depending on the material properties of the skin object.

In addition, the screw coupling method of the physical coupling method has the disadvantage that the work is cumbersome and difficult because the operator has to tighten and fix the worker one by one, the work efficiency and productivity is reduced, and the tightening state is naturally released by the external force during use, male and female ornaments The method of combining by pressing and deforming is difficult to use a separate crimping tool or a press device, and the male and female ornaments are easily rotated due to the occurrence of gaps when receiving external forces due to the characteristics of maintaining the mutually coupled state only by simple frictional force. And not only flow, but in severe cases, the decoration is worn, there is a noise is generated and there is a problem that the appearance and appearance of the skin is damaged by being separated and separated from the skin.

Therefore, the present inventors have developed a new type of male and female coupling type ornament after many years of research in order to solve various problems and limitations of the conventional ornament, which is disclosed in Korean Patent Publication No. 10-1139106. Is disclosed.

That is, in the conventional decorative tool previously developed by the present invention, as shown in FIG. 1, the first annular protrusion 13 protrudes from the hollow 12 edge of the plate body 11, and the first annular protrusion ( 13, the first eyelet 10 having a plurality of fitting protrusions 14 formed at regular intervals around the inner surface of the plate 13, and the hollow 22 of the plate body 21 so as to correspond to the first eyelet 10. Second eyelets protruding from the second annular protrusion 23 and having a plurality of fitting grooves 24 to which the fitting protrusions 14 are coupled at regular intervals around the outer surface of the second annular protrusion 23. It consists of 20.

In addition, in order to ensure that the mutual coupling between the first eyelet 10 and the second eyelet 20 can be made firmly by an interference fit or interference fit method, the inner circumference of the first annular protrusion 13 and the second annular protrusion The outer circumference of the 23 is formed without assembly tolerances with each other, and the size of the outer surface of the fitting protrusion 14 and the inner surface of the fitting groove 24 are formed without assembly tolerances with each other.

Such conventional ornaments are molded by casting methods, such as die casting, to produce a luxurious image and a precious metal feel, and to perform a surface treatment of coating a thin film of gold or silver with electroplating to improve gloss and improve corrosion resistance. Done.

However, due to the above-described structural characteristics and the characteristics of performing electroplating with post-processing, the overall thickness becomes slightly thick due to the plating layer formed after the plating operation, and in particular, the outermost end of the fitting protrusion 14 of the first eyelet 10 and the second eyelet. Edge portions such as the edge of the fitting groove 24 of the 20 may be further unevenly coated by the current difference generated during the electroplating process, and as a result, the thickness of the plated layer may be thicker. Interfere with the combination of the second eyelet 20 is not easily engaged.

Accordingly, the first protrusion 10 and the second eyelet 20 must be positioned exactly on the same central axis so that the fitting protrusions 14 of the first eyelet 10 are fitted with the fitting grooves 24 of the second eyelet 20. In addition to being inserted into the), when the worker is fixed to the skin attachment object, the fitting protrusion 14 of the first eyelet 10 is roughly estimated to rotate in the second state in close contact with the fitting groove 24 of the second eyelet 20. Joining work is very difficult and difficult, such as adjustment to be precisely meshed with each other, this takes a lot of time to join, which is bound to significantly reduce productivity.

Furthermore, the conventional ornament is that the first eyelet 10 and the second eyelet 20 are formed between the first annular projection 13 and the second annular projection 23 and the fitting projection 14 and the fitting groove 24. Since the first eyelet 10 is detached and separated from the second eyelet 20 in the axial direction even by a small external force, the first eyelet 10 is easily detached from the skin-attached object such that the first eyelet 10 is crushed and deformed by pressing force. There is a relatively weak limit.
