BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to metal tapezippers that can be used in products such as plastics, metal bags, or metal decorative clothes.

Known conventional zippers are classified into two types, one of which is a metal bobbin zipper with a combination of a fiber tape and a metal bobbin, and the other is divided into a synthetic resin zipper in which a synthetic tape is bonded to a fiber tape.

The two types of zippers are mainly used for clothes, bags, etc. without inconvenience, but the use of the above-mentioned fiber tapes is not suitable for products such as plastic or metal bags, sports shoes, metal clothes (special use) and the like.

In other words, the plastic or metal products of the above-mentioned applications all require strong holding strength and stability, so the two conventional zippers made of fibrous tapes are very weak in terms of strength, very unstable in terms of visual appearance, and can be used for a long time. Has the problem of tearing.

Therefore, the use of metal, i.e. metal tapes, with metal tapes is preferable for the above-mentioned products. However, metal tapes are less flexible, such as fiber tapes, and are very difficult to handle or handle metal plate materials in manufacturing and working processes. There is a difficult problem, and the choice of introduction with suitable flexibility and other conditions is a problem, so the need for a metal tape zipper is desperate while not being implemented.

Another problem is that the elements attached to the edge of the metal tape, that is, the coupling means with the zipper teeth.

In other words, if the zipper is to be firmly fixed without leaving the tape, the edge of the tape should be thickened to prevent the tooth from slipping out. Even if the metal tape is selected as a flexible material, it is difficult to form a thick knot by rolling the joint. There is a risk of deforming due to the compressive force applied when attaching the tooth, there is also a problem that the tooth can flow and detach when used for a long time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pure metal zipper in which both the tape and the tooth are made of metal without using synthetic resin or fiber tape, and used for metal products such as metal bags or metal clothing or metal ornaments, and suitable for metal products. By making the zipper coincide with each other and matching the pure metals together, the decorative aesthetics and the visual aesthetics can be highlighted and strength.

Another object is to form a metal tape integrated by connecting a plurality of pieces of metal with a metal wire, while having the same flexibility as a fiber tape, but having strength and stability as a metal material, and providing easy manufacturing and mass production.

When described in detail by the accompanying drawings the configuration and embodiment of the present invention as follows.

The metal taper zipper of the present invention may be made of non-ferrous metal sheet such as aluminum, copper plate or stainless steel, which is corrosion-free and has high strength, and may use other metal materials of similar performance.

The tape fabric material is cut into long tape-shaped materials by a separate processing machine to have U-shaped grooves 3 continuously at regular intervals as shown in FIG. 3 so that a plurality of pieces 2 are formed continuously, and their rear ends are The metal tape fabric 1 connected to the unitary body by the connecting piece (4) is formed to form, at this time, the work for processing the hole (4) for each end piece is also made.

The metal tape fabric 1, which has undergone such a process, is bent at the end of each piece 2 as shown in FIG.

That is, the metal tape fabric 1 is first bent into a mold as shown in FIG. 5a and then subjected to secondary processing into a mold in FIG. 5b, and then the metal wire 5 is bent in the process of FIG. 5c. In the state of FIG. 5D and FIG. 5E, the metal wires 5 are compressed and bent in a circular ring shape so as to be fixed to the core in the process of FIG. 5D and FIG. 5E. The metal tape (A) connected by the processing is completed.

The metal wire 5 is a non-ferrous metal material having no corrosion, tough rigidity and flexibility, and may be made of another metal and resin material having similar conditions.

The metal tape (A) of the line processing is completed in this way is vertically supplied to the conventional known zipper molding machine (7) is to be processed to combine the elements, that is, the metal teeth (8) to the metal tape (A).

The conventional known zipper molding machine 7 is supplied with a tape fabric vertically as shown in Figs. 6 and 7 (Fig. 7), and horizontally while the metal tube 9 is processed with a toothbrush (Fig. 6). The teeth processed at the intersections of the teeth are bitten by the tape and immediately acting on both sides of the pressing plate 10 to close the wings of the teeth so that the teeth are fixed to the tape.

Therefore, the metal tape (A) of the present invention is supplied to a known zipper molding machine (7) after pre-processing is continuous continuous metal nail 8 is pressed and fixed to the end pieces of each piece 2 as shown in Figs. I will work.

At this time, the metal tape (A) of the present invention is that each piece piece (2) is periodically lowered by one pitch bar, each piece piece (2) and metal teeth (8) vertically so as to exactly match the center line (Q) By adjusting the dropping device, the combination thereof can be made precisely, and each piece 2 can be treated like a flat tape because it is fixed without flow by the rear connecting piece 4 and the metal wire 5 of the front end.

After the metal tape (A) and the metal teeth 8 are vertically dropped on the zipper molding machine 7 in a coupled state (FIG. 9), each piece (2) is cut by cutting the rear connecting piece 4 with a separate cutter. ) Are connected only by the metal wires 5 to complete the molding operation of the metal tape zipper of the present invention.

Such a metal tape zipper of the present invention can be handled in the same manner as the existing zipper and have the same function by fitting the slider 11 by engaging in two lines facing each other as shown in FIG.

In addition, since the metal tape zipper of the present invention is attached to the product, both (product and zipper) are attached to the metal thread by hand as shown in FIG. 2 without using a sewing machine because of the specificity of metal. If the part is bent as shown in Fig. 8b, it can be easily woven using a metal thread or a hook when attached to a product.

The metal tape zipper of the present invention as described above is a pure metal zipper made of metal with tape and teeth, which can be used for products that require it, thereby obtaining decorative and visual aesthetics by mutual metal matching and obtaining necessary firmness. In particular, since the tape is a metal material, but each piece is a separate piece, and the pieces are integrally connected to each other by a flexible metal wire (5), each piece can have the required flow force and can smoothly work with flexibility such as a fiber tape zipper. It is.

In addition, the end portion of each piece (2) is formed of a ring-shaped bent portion (6) made of a metal wire (5) as a core material, the bent portion (6) protruding when the metal claws (8) is coupled to a solid locking step The metal wire 8 can be stably fixed without fear of flow or detachment. Especially, since the metal wire 5 inside the bent part is made of metal, it is also crushed under pressure when forming the bent part or when applying the metal ear. Without losing or deforming, it has a strong bearing force against external force, and thus, it is possible to retract the metal bristle with strong pressure while maintaining the stability of the bent portion, thereby providing a strong and strong metal zipper.

Claims (1)

The metal tape is formed at the end of each piece of metal tape by the annular bent of the metal wire, and each piece is provided with a metal tape connected by one metal wire, and the metal teeth are attached to the bent portion of each piece. Metal tape zipper, characterized in that to form a zipper of pure metal material.
