Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of slide fastener of a slide fastener.

[0002]

[Prior art]

 Generally, the teeth of a slide fastener are opened and closed by pulling a sliding bracket combined with the tooth using a pull tab. For this reason, in order to make the slide fastener have a change, a method of combining pull tabs of different types using a pull tab connecting means of a slide fitting has been adopted.

[0003] In the conventional slide fastener slide fitting shown in Fig. 1, one end of a strip-shaped locking means is fixed at an appropriate position on an upper surface thereof, and is extended in an arch shape toward a rear end. The other end is formed. When a pull tab is combined with the slide fastener of the conventional slide fastener, the following defects occur. 1. Since the gap between the rear end of the locking means of the sliding bracket and the top surface of the sliding bracket body is too large, the sliding brackets collide and come into contact with each other due to the vibration of the conveyor during the transportation process on the conveyor. Or slip (see Fig. 2), which could lead to failure of the sliding hardware. 2. Since the gap between the rear end of the locking means of the slide fitting and the upper surface of the slide fitting body is too large, the other end of the locking means is inserted into the connection hole of the pull tab, and then the tool is inserted into the locking means. It is necessary to press the upper surface of the sliding fitting to connect and fix the locking means and the pull tab (see Fig. 3). At this time, the other end of the locking means and the lower surface of the sliding fitting are sandwiched by the tool. However, since the lower surface of the slide is pressed upward by the tool, the orbit of the slide is compressed and becomes flat or slightly deformed (see Fig. 4). There was something.

In order to solve the above-mentioned various drawbacks caused by an excessively wide gap between the upper surface of the slide fitting and the other end of the locking means, a groove penetrating the rear end face of the slide fitting has already been provided. A slide fitting having a spring and a locking block mounted in the groove is provided (see FIG. 5). This enables the locking block to slide back and forth by using the elasticity of the spring, and when connecting the pull tab to the slide bracket, simply press and move the locking block to lock the pull tab connector. Since the pull tabs are connected in a locking manner, there is no need to press the locking means with a tool after inserting another end of the locking means into the pull tab as in the technique of FIG. However, this sliding metal fitting was complicated and inconvenient to assemble, and relatively expensive and time-consuming to process.

[0005] In addition, a technique shown in Fig. 6 is provided so that a pull tab having a special or different thickness connecting body can be connected to the sliding metal fitting. One of the locking means is fixed at an appropriate position on the front end of the upper surface of the sliding means, and the locking means is extended rearward and curved to form another end of the locking means. One connecting piece is combined with the front end of the locking means, and the front end of the connecting piece is bent upward in a U-shape, and the connecting piece is provided with a spring piece, and the spring piece is used as a fixing hook. An annular hook is formed together with the bottom surface of the extension end.

[0006] The slide fitting of FIG. 6 has the following disadvantages during use. 1. The connection of the pull tab to the sliding bracket is made by connecting the pull tab to the connecting piece.When a special or relatively thick pull tab is inserted, the elastic spring piece must first be pressed, and the pull tab connected to the fixing hook. A gap is formed between the pull tabs to pass through and engage in the annular hook, but the space in this gap is too small to allow the penetration of special or relatively thick pull tabs (see FIG. 7). ). 2. When the connecting piece is combined with the locking means, the other end of the locking means is inserted into the connecting hole of the connecting piece, because the gap between the other end of the locking means of the sliding piece and the upper surface of the sliding piece is too large. It is necessary to press the locking means against the upper surface of the slide fitting by holding it with a tool to connect and fix the locking means and the connecting piece. At this time, the other end of the locking means and the lower surface of the slide fitting are required by the tool. A force is applied across the sliding bracket, but the lower surface of the sliding bracket is pressed upward by the tool, so that the track of the sliding bracket is pressed and flattened or slightly deformed, which makes it impossible to use the sliding bracket. There was something.

[Problems to be solved by the invention]

 The present invention has been made in view of the above-mentioned drawbacks of the prior art, and has been made in order to solve the problem, that is, the present invention can combine a pull tab with a special or different thickness connecting body. It is another object of the present invention to provide a structure of a slide fastener of a slide fastener which can be easily manufactured and processed and can reduce the occurrence of defective products during the manufacturing and processing.

[0008]

[Means for Solving the Problems]

 According to the invention of claim 1, the front and rear edges of one long strip are extended upward on the upper surface of the slide fastener of the slide fastener along the sliding direction of the slide fastener and then bent inward to form two slide fasteners. A sliding fastener for a slide fastener is formed by fixing an annular hook having elasticity with its edges overlapping one another up and down.

[0009]

[Embodiment of the invention]

 FIG. 8 shows the slide fastener of the slide fastener of the present invention. As shown in the figure, the present invention is achieved by extending the front and rear edges 101 and 102 of one elongated strip 100 upward and then bending them inward to overlap the extended ends with each other. An annular hook 10 having an elastically openable and closable locking upper section 103 and a locking lower section 104 is provided. The lower surface of the annular hook 10 is formed on the upper surface of the slide fastener 1 of the slide fastener. The sliding bracket 1 is fixed along the sliding direction.

With this structure, the connecting members 20 of different thicknesses of the pull tab 2 are slid in the direction of the engaging portion upper stage 103 while pressing the engaging portion lower stage 104 with the connecting members 20, and are hung on the engaging portion upper stage 103. If the contact portion is restored to the lower portion 104 of the locking portion and the upper portion 103 of the locking portion, the connecting member 20 of the pull tab 2 and the slide metal can be connected (see FIG. 9). Its practicality and value have been greatly enhanced.

[0011]

[Effect of the invention]

 According to the above-described structure, the front and rear edges 101 and 102 of one elongated strip 100 are respectively stretched upward and then bent inward, and the stretched ends are overlapped with each other to have elasticity. An annular hook 10 having an upper portion 103 and a lower portion 104, which can be opened and closed, is formed. The annular hook 10 can easily pierce the pull tab 2 provided with a connecting body 20 having a different thickness. Therefore, the present invention solves the problem of the mutual scratching of the locking means that occurs in the transportation process at the time of manufacturing the slide fitting, the deformation of the track of the slide fitting at the time of processing, and the processing in the conventional technology. This solves the problem of labor, time and cost, greatly improving the practicality of the sliding metal fittings, and provides the effect of facilitating the processing.
