KEY RING WITH PROTRUSION FOR PLATING}

The present invention relates to a key ring in which the plating protrusion is protruding. More specifically, the plating protrusion is further protruded on the outer side of the elastic piece of the key ring configured in the key wallet for holding a plurality of keys. The spaced parts are formed between the binding pieces to prevent the elastic extension and the binding pieces from sticking together by the plating solution after the key ring plating operation, thereby improving the plating workability and not limiting the thickness of the plating layer. The present invention relates to a key ring in which plating projections protrude to improve productability.

In general, modern people carry three or more keys, such as a house key, a car key, a bicycle key, and a locker key, and a key wallet is used to store many of these keys in one place.

The inside of the key wallet is configured with a key ring that can hold a plurality of keys, and when looking at the configuration of the key ring is configured in the conventional key wallet as shown in Figure 1 rolled up in a round arc at the bottom Jean mounting portion (1) is configured and the mounting portion (2) mounted on the inner surface of the key wallet, the fixing portion (3) is hinged to the upper portion in the longitudinal direction inside the mounting portion (2), and the fixing portion (3) It is composed of a key ring formed by an elastic piece 4 and a binding piece 5 on an upper end of the lower side.

The conventional key ring configured as described above pushes the elastic piece 4 inwardly so that the elastic piece 4 and the binding piece 5 are opened so that the key is inserted into the elastic piece 4 pushed inward. The elastic piece is moved back to the binding piece 5 so that the elastic piece 4 and the binding piece 5 come into close contact with each other so that the key inserted therein is stored.

Therefore, the user keeps and carries various keys such as a house key, a car key, and a locker key in a plurality of key rings configured in the key wallet.

On the other hand, the key ring mounted on the key wallet is mass-produced through the plating operation of the surface bar, the plating operation of the key ring is to proceed with the plating operation after assembling each of the components shown in Figure 1, When assembling each component after the plating work first, each of the components due to the problem that the plating layer plated on each component is scratched due to scratches, and the thickness of the plating layer is different together with the phenomenon that the product quality is poor. The elements are assembled first and then plated.

However, the elastic pieces 4 of the key ring and the contact surface 6 of the binding piece 5 formed in close contact with each other by elasticity in the process of carrying out the plating operation after assembling in this manner are brought into close contact with each other. Since the plating liquid does not adhere to the contact surface 6 of 4) and the binding piece 5, there exists a problem that plating property falls.

In addition, since the elastic piece 4 and the binding piece 5 adhere completely by the plating liquid plated on the outer surfaces of the elastic pieces 4 and the binding pieces 5 which are closely adhered to each other by elasticity, these elastic pieces after the plating operation. (4) and the binding piece 5 is not separated from each other there is a problem that the key is not easy to insert.

In addition, even if the elastic pieces 4 and the binding piece 5 which are stuck together by the plating liquid are forcibly knocked out, a phenomenon in which the plating liquid around the elastic pieces 4 and the binding piece 5 is forcibly blown out may occur. There is a problem that the marketability is greatly reduced.

Furthermore, in order to prevent the elastic pieces 4 and the binding pieces 5 from sticking to each other by the plating solution, a thin plating layer is formed to perform the plating operation. However, when the thin plating layer is formed in this way, the plated plating layer is easily worn out. As well as the phenomenon occurs, bubbles are generated on the surface of the plating layer or dirty foreign matter adheres to the surface of the plating layer, which greatly reduces the commerciality of the key ring or increases the defective rate.

In addition, in order to insert the key into the conventional key ring in which the elastic piece 4 and the binding piece 5 are in close contact with each other, it is necessary to open the elastic pieces 4 and the binding piece 5 in close contact with each other by the contact surface 6. Due to the difficulty of opening them apart from each other, there is a problem in that it is not easy to insert a key.

The present invention has been devised to solve the problems appearing in the plating operation of the key ring in the prior art, by further protruding the projection on the outer surface of the elastic piece in close contact with the binding piece of the key ring spaced between the elastic piece and the binding piece by the projection. By forming the space portion, the plating liquid is evenly applied to the binding piece and the elastic piece in the plating operation to improve the plating effect, and to increase the thickness of the plating layer, and to prevent the elastic piece and the binding piece from sticking together by the plating solution. The purpose of the present invention is to provide a key ring with a protruding plating for preventing the product from being improved significantly.

As a means for achieving the above object, the key ring protruding from the plating protrusion of the present invention includes an arc-shaped connection piece, an elastic piece extending from one side of the connection piece, and an extension from the other side of the connection piece to the outside of the elastic piece. In the key ring formed of the binding piece located on the side, the outer surface of the elastic piece is further formed with a projection forming a space portion spaced apart between the elastic piece and the binding piece.

The key ring in which the plating protrusion protrudes according to the present invention has a protrusion formed on the outer surface of the elastic piece facing the binding piece, so that a space part spaced between the binding piece and the elastic piece is formed and the plating solution is bound during the plating operation. Evenly buried in the piece and the elastic piece, the plating properties are greatly improved.

In addition, since the plating operation is performed in a state where the binding piece and the elastic piece are spaced apart from each other by projections, the phenomenon that the binding piece and the elastic piece are stuck to each other by the plating liquid is prevented.

In addition, the binding piece and the elastic piece can be formed by spaced apart by the projection to form a thick thickness of the plating layer to improve the plating effect as well as to prevent the formation of bubbles during the plating operation and greatly improve the quality of the product. The defective rate can be reduced.

Hereinafter, the structure and operation of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, the terminology or words used in the present specification and claims are based on the principle that the inventor can properly define the concept of the term in order to best explain his or her design in the best way. It should be interpreted as meanings and concepts corresponding to the technical idea of

As shown in the present invention, the key ring protruding from the plating projection, the circular arc-shaped connecting piece 11, the elastic piece 12 extending from one side of the connecting piece 11, and the connecting piece 11 A key ring formed of a binding piece 13 extending from the other side and located on the outer side of the elastic piece 12, the outer surface of the elastic piece 12, the elastic piece 12 and the binding piece 13 The protrusions 15 forming the space 14 spaced apart therebetween are further formed.

The protrusion 15 is formed by bending the elastic piece 12 and the pressing piece 13 on both sides of the connecting piece 11, and then placing the elastic piece 12 on the press molding apparatus. The protrusion 15 is formed to protrude to the outer surface side of the elastic piece 12 by the strike of the device.

In this way, the protrusions 15 are protrudingly formed on the outer surface side of the elastic piece 12, and then bent such that the elastic piece 12 and the binding piece 13 face each other with respect to the connecting piece 11 so as to face each other. The protrusion 15 is positioned between the elastic piece 12 and the elastic piece 12 so that the space 14 spaced apart between the elastic piece 12 and the binding piece 13 is naturally formed.

Accordingly, when the plating operation of the key ring is performed by the space portion 14 formed between the elastic piece 12 and the binding piece 13, the plating pieces are faced to each other by the space part 14. And it is evenly buried in the binding piece 13, the plating property is greatly improved.

In addition, the elastic piece 12 and the binding piece 13 are brought into close contact with each other by the projections 15 instead of the surface key of the conventional key ring through the space portion 14 formed by the projections 15. By preventing the elastic pieces 12 and the adhesion pieces 13 from sticking together, the problem caused by dropping the elastic pieces and the adhesion pieces closely contacted after the plating operation is solved.

Furthermore, the elastic piece 12 and the binding piece 13 are brought into close contact with each other by the projections 15, rather than the close contact of the conventional key ring, through the space portion 14 formed by the projections 15. Easily sandwiched between the elastic piece 12 and the binding piece 13, the usability of the key ring is greatly improved.

In addition, the plating layer can be formed thick, so that scratches due to scratches can be prevented, and bubbles can be prevented from occurring during the plating operation.

While the present invention has been described in connection with what is presently considered to be preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is to be understood that the technical scope of the present invention includes all of the techniques that can be used by those skilled in the art to which the present invention belongs.
