Slider for self-aligning slide fastener

Abstract

To provide a self-aligning type fastener slider capable of being smoothly opened and closed without damaging a pull tab of the slider, a fastener element and a reinforcing film even if the slider is forcibly pulled up by surely confirming that right and left elements are arranged side by side by the feeling of a hand without confirming by eyes when an insert pin is inserted into a box.SOLUTION: When the insert pin 3 is inserted into the box 1, the bowl-shaped elastic member 4, the bowl-shaped hard member which moves right and left by the spring, or the leaf spring-shaped convex portion of the elastic member attached to the insert pin engages with the convex portion of the insert pin on the side wall 5 of the box and the concave portion 6 of the side wall 5 at that position, and the slider is smoothly pulled up at the position where the fastener elements 8 of the stringers 9 engage with each other, thereby preventing the pull fastener element reinforcing film 10 from being damaged.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to an opening device in which a slider, a box pin, a box, and an insert pin are integrally formed for use in a slide fastener. [Background technology]

[0002] The opening device, which is formed by a slider, a box pin, a box, and an insert pin, is a fastener opening device used for a shirt or a jumper, etc., to separate and fasten the left and right sides of the fastener chain.

[0003] Previous opening devices involved pushing a box pin fixed to one stringer and a stringer with a butterfly pin attached horizontally into the box, combining the box pin and butterfly pin inside the box.

[0004] When combining the box pin and the insert pin, if the insert pin is inserted even slightly out of alignment, the fastener elements will not mesh, and if the slider is forcibly lifted, the slider will crack, the reinforcing film will tear, or the fastener elements will come off the tape.

[0005] [Patent Document 1] Patent application No. 04-205210 [Patent Document 2] Application No. 1970-069868 [Patent Document 3] Application No. 59-083386 [Patent Document 4] KR-A-160002002 Summary of the Invention [Problem to be solved by the invention]

[0006] According to the above-mentioned prior art, slide fasteners used in dress shirts, jackets, etc. are operated from the underside of the garment when worn, so the operator does not have a clear line of sight and must insert the butterfly pins at the ends of the left and right stringers into the box with the box pin by feel and experience. If the butterfly pin does not fit properly into the box, the zipper elements will not engage, and when the slider is lifted up, the slider pull tab will break, the element will come off, or the reinforcing film will tear. [Means for solving the problem]

[0007] When inserting the insert pin horizontally into the box, a bowl-shaped protrusion made of a soft material with a part of the protruding bowl-shaped protrusion is attached to the side surface inside the box so that it can be confirmed by touch even if it cannot be confirmed completely with the eye, and the insert pin to be inserted is also provided with a recess in a position that meets the bowl-shaped protrusion so that the bowl-shaped protrusion can be accommodated, so that it can be sensed by touch that the insert pin has been inserted all the way to the back. This prevents damage to the slider pull tab, zipper element, and reinforcing film. [Effects of the Invention]

[0008] In the present invention, the insert pin is not inserted halfway into the box, and the insert pin and the box can be fixed securely at the position where the left and right elements mesh, preventing damage to the slider pull tab and elements and tearing of the reinforcing film. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is a plan view of a typical slide fastener. [Figure 2] 2 is a cross-sectional view taken along the arrow AA in FIG. 1, showing a bowl-shaped convex portion of an elastic body attached to an insert pin and a concave portion attached to a box according to the present invention. [Figure 3] 2 is a cross-sectional view taken along the arrow AA in FIG. 1, showing a leaf spring-shaped convex portion of an elastic body attached to an insert pin and a concave portion attached to a box according to the present invention. [Figure 4]This is a cross-sectional view taken along the line AA in Figure 1, showing a convex portion of a hard bowl attached to an insert pin according to the present invention, which allows the bowl to move left and right using a spring, and a concave portion attached to a box. DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the present invention is shown in Figure 1. In the figure, the left and right elements mesh properly when the slider is raised at the position where the bowl-shaped protrusion halfway out of the box meets the recess of the insert pin, which has the same shape as the bowl-shaped protrusion.
