Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same or similar parts are denoted by the same or similar symbols. In addition, the embodiment shown below exemplifies a specific example for embodying the technical idea of the present invention, and the technical idea of the present invention is not to specify the structure, arrangement, material, and the like of the component.

(First embodiment)

Fig. 1 is a front view of a zipper 1 obtained by attaching a slider 8 to a chain 2 having a zipper opening and closing member 10 according to a first embodiment of the present invention. The chain 2 includes a pair of chain belts 3, and the like, and a chain row 6 including a plurality of fastener elements 5 arranged along the opposite side edge portions 41 of the pair of fastener tapes 4; a stopper 7 Disposed on one end of the element row 6; and a zipper opening and closing member 10 disposed at the other end of the element row 6.

As shown in FIG. 7, the plurality of sprocket teeth 5 respectively include an engaging head portion 51 having an elliptical shape that is longer in the longitudinal direction of the zipper tape 4 in plan view, and a neck portion 52 that is self-engaging head 51 toward the zipper cloth. The belt 4 extends in the width direction; and the base portion 53 extends from the neck portion 52 and further in the width direction of the fastener tape 4. The engaging head portion 51 of the opposing sprocket 5 and the neck portion 52 are engaged or disengaged by the slider 8 on the side edge portion 41 of the fastener tape 4, whereby the opening and closing of the slide fastener 1 is performed.

As shown in FIG. 2, the zipper opening and closing member 10 includes a latch 11 which is disposed at an end portion of a fastener element row 6 of one of the zipper tapes 4 (the zipper tape 4 on the left side of the paper surface of FIG. 2); The end of the element row 6 of the other zipper tape 4 (the zipper tape 4 on the right side of the paper of FIG. 2) is extended across the zipper tape 4 of both sides, and the pin 11 can be received. And the tube pin 13 is opposite to the pin 11 on the other zipper tape 4, and is disposed between the element row 6 and the tail barrel 12, and forms a first line with the tail barrel 12. The manner of the gap 14 is configured to be separated from the tail cylinder 12.

The plug 11 is preferably divided into at least two portions via the second gap 15. In Figure 2, An example in which the plug 11 is divided into two plugs 11a and 11b via the second gap 15 is shown. The plug 11 is generally a member having a shape that is elongated compared to a component such as the fastener element 5 or the stopper 7, and is disposed at the end of the fastener tape 4, and therefore, if it is not manufactured using a strong raw material, Bending in the case of pinching, or breakage due to long-term use or contact with the outside. According to the zipper opening and closing member 10 of the first embodiment, since the pin 11 is divided into a plurality of smaller parts, it is more resistant to external force than the conventional elongated pin, and is manufactured by using a material having a relatively weak strength as a raw material. In the case of the plug 11, it is also less likely to be damaged or deformed.

Here, as shown in FIG. 1 , the second gap 15 is preferably exposed to the outside of the tail pipe 12 when the pin 11 is received in the tail pipe 12 , and is disposed in the pin that is exposed from the tail pipe 12 . 11 on one part. In this case, when an external force is applied to the vicinity of the tailing cylinder 12 due to the bending of the zipper tape 4 or the like, the zipper tape 4 is also bent by the first gap 14 and the second gap 15 provided in the vicinity of the tailing cylinder 12. Therefore, the external force is not easily transmitted to the plug 11 or the pin 13, so that the breakage or deformation of the pin 11 or the pin 13 is suppressed.

The size of the first gap 14 and the second gap 15 is not particularly limited. However, if the gap is too large, there is a possibility that the sprocket 5 adjacent to the pin 11a and the pin 13 is disengaged or foreign matter is caught. If the gap is too small, the effect of suppressing the breakage of the plug 11 and the pin 13 is small. Therefore, the size of the gap is preferably set to be such that the sprocket 5 disposed in the longitudinal direction of the fastener tape 4 is spaced apart from the fastener element 5. The first gap 14 and the second gap 15 can be arbitrarily set in accordance with the size of the fastener element 5 and the size of the zipper opening and closing member 10 corresponding thereto.

As shown in Fig. 2, the tail cylinder 12 is extended at the end in the longitudinal direction of the fastener tape 4 in the width direction of the fastener tape 4 (the horizontal direction of the paper surface of Fig. 2). As shown in FIG. 3, the tail cylinder 12 is attached to the opposite surface 121 of the pin opposite to the plug 11, and a slit 122 is formed along the longitudinal direction of the fastener tape 4. On the deep side of the slit 122, as shown in FIG. 4, a cavity portion 124 having a cavity for receiving the plug 11b is formed. The latch 11b is housed in the cavity portion 124. As shown in FIG. 2, the pin 13 and the end of the zipper tape 4 in the longitudinal direction are provided on the zipper cloth. The tail cylinder reinforcement portion 123 extending in the width direction of the belt 4. The open end cylinder reinforcing portion 123 and the open end cylinder 12 are formed by integral molding. By the tail cylinder reinforcing portion 123, the strength of the end of the fastener tape 4 can be improved. For the same purpose, the pin 11b opposed to the pin 13 is formed integrally with the pin 11b to form a pin reinforcing portion 113 extending in the width direction of the fastener tape 4.

The pin 13 is disposed to have a first gap 14 between the tail pipe 12 and the tail pipe 12 . The pin 13 is generally connected to the open end barrel 12. Therefore, in the case where the fastener tape 4 in the vicinity of the opening and closing member 10 is bent, there is a case where the joint portion between the tail cylinder 12 and the tubular pin 13 is broken or cracked. In the first embodiment, since the first gap 14 is formed, even when the fastener tape 4 in the vicinity of the opening and closing member 10 is bent, no excessive force is applied to the tubular pin 13, and the tubular pin 13 is damaged. Or deformation is suppressed.

As shown in FIG. 3, the cylinder pin 13 has a locking convex portion 132 that protrudes from the latch opposing surface 131 facing the plug pin 11 toward the plug pin 11. As shown in FIG. 2, the locking convex portion 132 is disposed along the longitudinal direction of the fastener tape 4, and is gradually protruded toward the pin 11 side from the side of the pin 13 of the pin facing surface 131 toward the element row 6. The way it is configured. In order to accommodate the locking projection 132, a groove-shaped receiving recess 112 is engraved on the tubular pin facing surface 111 of the latch 11a facing the tubular pin 13. The accommodating recessed portion 112 is disposed along the longitudinal direction of the fastener tape 4 so as to extend over the entire tube pin facing surface 111 of the latch 11a.

The latch 11a opposed to the cartridge pin 13 is provided with a tab portion 117 which protrudes from the front surface 115 and the rear surface 116 of the latch 11a toward the tubular pin 13 side, respectively, and the fastener element row 6 of the opposite zipper tape 4 The neck portion 52 of the sprocket 5a (see FIG. 2) at the extreme end is engaged; and the cutout portion 118 is disposed on the front surface 115 and the back surface 116 of the latch 11a as a recess adjacent to the tab portion 117 and is received at the extreme end. The meshing head 51 of the sprocket 5a of the portion. By the engagement of the protruding portion 117 and the notch portion 118 with the engaging head portion 51 and the neck portion 52 of the fastener element 5a, even if the force for stretching the fastener tape 4 in the width direction acts, the fastener elements 5 are not easily disengaged from each other. . Further, even when a force applied from the front and back directions of the zipper tape 4 is applied, the plate-like locking convexity is applied. In a state in which the portion 132 is housed in the housing recess 112, the tab portion 117 and the slit portion 118 mesh with the engaging head portion 51 and the neck portion 52 of the fastener element 5a, so that the fastener elements 5 are not easily disengaged from each other.

In the zipper opening and closing member 10 of the first embodiment, the tail cylinder 12 and the tubular pin 13 are disposed via the first gap 14, and the plug 11 is divided into the plug 11a and the plug 11b via the second gap 15. Thereby, even when the fastener tape 4 is bent or deformed by an external force, no excessive force is applied to the plug 11, the tail cylinder 12, and the cylinder pin 13, respectively. As a result, even when a material having a relatively weak strength is used as the material of the zipper opening and closing member 10, breakage of the opening and closing member 10 is less likely to occur, and since various resins can be used as the material of the zipper opening and closing member 10, production is performed. Sexual improvement. When the material considering the environment is used as the material of the zipper opening and closing member 10, the disposal after use as the zipper 1 is also easy. For example, as a material for the zipper opening and closing member 10, for example, in addition to a resin such as a polyacetal, a metal such as iron, a copper alloy, a zinc alloy, an aluminum alloy, or a stainless steel, polyamine or polyphosphate may be preferably used. A thermoplastic synthetic resin such as propylene, polybutylene terephthalate or polycarbonate.

Further, according to the zipper opening and closing member 10 of the first embodiment, and the chain 2 and the zipper 1 using the same, the first gap 14 and the second gap 15 are formed around the opening barrel 12. When the slider 8 is slid and the sprocket 5 is engaged with each other, the first gap 14 and the second gap 15 can be used as a foreign object when a foreign object such as sand, mud, a thread, or dust is accidentally caught. It functions as a space to be discharged.
