The other end of the row of the fastener elements 3a and 3b is an end portion that faces the side in which the slider 7 is slid in the longitudinal direction of the fastener fabrics 2a and 2b and is pulled in the direction in which the slide fastener 1 is pulled. Further, the front and back directions of the chain fabrics 2a and 2b are defined as "up and down direction" or "height (depth) direction". In the present embodiment, the surface side of the chain fabrics 2a and 2b is referred to as "upper", and the back side of the chain fabrics 2a and 2b is referred to as "lower side".

The chain fabrics 2a and 2b are formed of a belt-like material woven or knitted by synthetic fibers or natural fibers, and the cores 5a and 5b are disposed along the chain side edge portions 21a and 21b extending in the longitudinal direction. As shown in Fig. 2, the fastener elements 3a and 3b have a shape substantially symmetrical with respect to the front and back surfaces of the fastener fabrics 2a and 2b around the chain fabrics 2a and 2b. The specific shape of the fastener elements 3a and 3b is not particularly limited. For example, as shown in Fig. 12, the fastener element 3b includes: a base portion 35 fixed to the chain cloth 2b; a neck portion 36 projecting from the base portion 35 toward the opposite side of the chain cloth 2a; and a side from the neck portion 36 and further toward the chain cloth 2a The bulging engagement head 37. The sliders 7 shown in Fig. 1 can be slid up and down on the fastener elements 3a, 3b to engage or disengage the fastener elements 3a, 3b.

As shown in FIG. 2, the slider 7 includes a slider main body 71 that houses the fastener elements 3a, 3b for engaging or disengaging the fastener elements 3a, 3b, and a tab holding portion 74 that is disposed on the slider. On the surface of the main body 71; and a pull tab 75 supported by the pull tab holding portion 74. As shown in Fig. 1, the lower stopper 4 is formed by injection molding and formed in the vicinity of the lowermost end of the row of the fastener elements 3a and 3b, and has a substantially square outer shape. On the other hand, the upper stoppers 6a and 6b are formed by injection molding and formed in the vicinity of the uppermost end of the row of the fastener elements 3a and 3b, and are circular in plan view in Fig. 1 . The upper stoppers 6a, 6b are attached to the front and rear directions of the chain fabrics 2a, 2b to have a height that does not enter the mouth end (i.e., the end portion of the slider 7 on the side of the direction in which the zipper 1 is pulled). And formed. The shape of the lower stopper 4 and the upper stoppers 6a and 6b is not limited to the example shown in Fig. 1, and may of course be various shapes.

Resin can be used as the fastener elements 3a and 3b, the slider 7, the lower stopper 4, and the upper stoppers 6a and 6b. As a specific example, polyacrylamide (PA), polyacetal (POM), or polyacetal can be used. Polycarbonate (PC), modified polyphenylene ether (m-PPE), polybutylene terephthalate (PBT), polyethylene terephthalate (polybutylene terephthalate) PET, polyethylene terephthalate), glass fiber-polyethylene terephthalate (GF-PET), cyclic polyolefin (COP, Cyclo polyolefin), and the like. The material of the fastener elements 3a and 3b, the slider 7, the lower stopper 4, and the upper stoppers 6a and 6b is not particularly limited as long as it is melted by ultrasonic vibration described later, and may be, for example, low in lead or tin. Melting point metal.

A decorative part 8 is attached to the surfaces 300, 400, 600, and 700 of at least one of the fastener elements 3a, 3b, the slider 7, the lower stopper 4, and the upper stoppers 6a, 6b. For example, the decorative parts 8 are arranged on the upper stoppers 6a and 6b as an example. As shown in Fig. 1, a first upper stopper 6a made of resin is placed on the chain side edge portion 21a at the uppermost end of the first chain cloth 2a. The second upper stopper 6b is disposed on the chain side edge portion 21b of the uppermost end of the second chain cloth 2b facing the first chain cloth 2a. The first upper stopper 6a includes a concave first accommodating portion 62a formed on the surface 600, a first decorative component 8a housed in the first accommodating portion 62a, and a first fixing portion 63a. The accommodating portion 62a is integrated, and the first decorative component 8a is fixed by being protruded from the first accommodating portion 62a. The second upper stopper 6b includes a concave second accommodating portion 62b formed on the surface 600, a second decorative component 8b housed in the second accommodating portion 62b, and a second fixing portion 63b. The accommodating portion 62b is integrated, and the second decorative component 8b is fixed by being protruded from the second accommodating portion 62b.

As shown in FIG. 1 and FIG. 4, the second upper stopper 6b is provided with a stopper portion 61 which is disposed on the chain side edge portion 21b and which is closest to the chain of the first upper stopper 6a among the rows of the fastener elements 3a. The teeth 3a (not shown) are opposed to each other and formed integrally with the second upper stopper 6b. The thickness of the stopper portion 61 in the front-back direction of the fastener fabric 2b is equal to the thickness of the fastener elements 3a, 3b, the length of the stopper portion 61 as viewed from the short side direction of the fastener fabric 2b, and the base portion 35 of the fastener element 3b. The lengths are approximately equal. By forming the stopper portion 61, it is possible to prevent the slider 7 from being detached from the fastener elements 3a, 3b, and to increase the strength when the chain fabrics 2a, 2b are stretched in the width direction.

As shown in FIG. 3, the first housing portion 62a includes a first groove 621 which is tapered in a downward direction (depth direction) of the upward stopper 6a, and a second groove 622 which is in the second groove 622. The upper side of the 1 slot 621 is connected to the first slot 621 and is connected to the surface 600. As shown in Fig. 5, the decorative part 8 is provided with a main body portion 81 which is located below the maximum diameter portion 82 with the largest diameter portion 82 whose cross section is the largest diameter, and which is tapered from the main body portion 81 upward. In the case of the exposed portion 83, the main portion 81 of the decorative component 8 is housed inside the first groove 621, and the exposed portion 83 is housed inside the second groove 622. As shown in FIG. 3, a chain cloth 2a having a winding core 5a at its tip end is embedded in the lower portion of the first housing portion 62a. In the present embodiment, it is preferable that the front end of the chain fabric 2a (core 5a) is located immediately below the center 623 (center axis C) of the first housing portion 62a or is displaced from the center 623 (center axis C). In other words, it is preferable that the center 623 (center axis C) of the first upper stopper 6a is located directly below the front end of the first chain cloth 2a embedded in the first upper stopper 6a, or is closer to the second chain than the front end. The cloth 2b side is deviated and configured. Similarly, it is preferable that the center (not shown) of the second upper stopper 6b shown in FIG. 1 or FIG. 4 is located at the front end of the second chain cloth 2b embedded in the inside of the second upper stopper 6b, or The distal end is arranged to be offset from the first link 2a side. The chain cloth 2a and the winding core 5a are arranged to be offset from the central axis C. Therefore, in the manufacturing method described later, the vibration when the decorative part 8 is fixed is difficult to be transmitted to the chain cloth 2a or the winding core 5a, so that it can be used for a short time. The fixing of the decorative part 8 is completed. Although it is not limited to the following, in order to efficiently fix the decorative part 8, the amount of deviation d4 from the front end of the chain cloth 2a (the front end of the winding core 5a) and the width direction (the short side direction) of the center C may be set (refer to FIG. 3). It is, for example, 0 mm or more, preferably about 0 to ~1 mm.

The length d2 in the short-side direction of the chain cloth 2a embedded in the first upper stopper 6a is preferably 50% or less, more preferably 25 to 50%, in the width direction of the maximum diameter d1 of the first housing portion 62a. . By adopting this configuration, when the decorative component 8 is fixed by ultrasonic vibration welding, the ultrasonic vibration is more easily transmitted to the resin layer constituting the first upper stopper 6a than the chain fabric 2a and the core 5a. Therefore, the fixing of the decorative part 8 can be performed efficiently in a shorter time. The distance d3 between the center (the deepest portion) 623 of the first housing portion 62a and the uppermost end of the chain cloth 2a (the winding core 5a) is usually set to be about 0 to 1 mm, although it is not limited to the following. Although the illustration and detailed description are omitted, the second housing portion 62b of the second upper stopper 6b may of course be substantially equivalent to the first upper stopper 6a.

The decorative part 8 is not particularly limited as long as it is a member for jewel decoration such as crystal, stone, or gemstone. The shape of the decorative part 8 is also not particularly limited. For example, as shown in FIG. 5 or FIG. 10, the decorative part 8 may have a shape (diamond shape) having a maximum diameter portion 82 whose cross section is the largest diameter as a boundary, and the front end portion is gradually formed from the maximum diameter portion 82 downward. The thin main body portion 81 and the exposed portion 83 having a tapered shape from the main body portion 81 upward. As shown in FIG. 6 , the decorative part 8 may have a shape in which the main body portion 81 has a columnar shape and has an exposed portion 83 which is tapered toward the upper end from the main body portion 81 with the largest diameter portion 82 as a boundary. As shown in FIG. 7 or FIG. 8 , the decorative part 8 may have a tapered shape including a main body portion 81 having a tapered shape in which the largest diameter portion 82 having the largest diameter from the cross section is tapered downward. As shown in FIG. 9, the decorative part 8 may also be spherical or elliptical in shape. As shown in FIG. 11, the shape of the exposed portion 83 which is tapered from the maximum diameter portion 82 to the upper end may be included.

The positional relationship between the decorative part 8 and the sub-female constituting members (the sprocket 3a, 3b, the slider 7, the lower stopper 4, and the upper stoppers 6a, 6b) is also not particularly limited, but is preferably, for example, a decorative part. The maximum diameter portion 82 of the eighth portion 8 is disposed below the surface 600 of the first upper stopper 6a so as to fix the decorative component 8 in the accommodating portion (the first accommodating portion 62a). Thereby, the decorative part 8 is stabilized in the accommodating portion and is not easily detached.

Further, the top surface of the exposed portion 83 of the decorative part 8 and the surfaces 300, 400, 600 of at least one of the sprocket 3a, 3b, the slider 7, the lower stopper 4, and the upper stoppers 6a, 6b may be The decorative parts 8 are fixed to the accommodating portions 32, 42, 62a, 62b, 72a, 72b, and 72c so as to be located on the same plane or disposed further below the surfaces 300, 400, 600, and 700. That is, in the example shown in Fig. 10, the top surface 83a of the exposed portion 83 of the decorative part 8 is placed on the same plane as the surface 600 of the first upper stopper 6a. Thereby, compared with the case where the exposed portion 83 protrudes from the surface 600 of the first upper stopper 6a, it is less likely to be affected by friction or the like due to external contact, and thus the decorative component 8 is less likely to fall off from the slide fastener 1.

When the decorative part 8 is attached, for example, the decorative part 8 is placed in the first housing portion 62a shown in FIG. Thereafter, ultrasonic waves of about 20 kHz, preferably about 20 to 40 kHz, are applied to the surface portion of the decorative component 8 from the upper surface of the decorative component 8 with respect to the resin layer constituting the first housing portion 62a using an ultrasonic transmitter. vibration. As shown in FIG. 5, by applying ultrasonic vibration, the resin in the vicinity of the boundary between the first groove 621 and the second groove 622 of the first housing portion 62a facing the largest diameter portion 82 of the decorative component 8 is melted. The side wall 64 of the second groove 622 in the first housing portion 62a is swollen to form a fixing portion 63a (first fixing portion) that covers one of the exposed portions 83. The fixing portion 63a melts and integrally forms one of the resins constituting the first upper stopper 6a. Therefore, the decorative member 8 is less likely to fall off than the case where the other member is fixed to the exposed portion 83, and the decorative part can be more firmly connected. 8 and the zipper constitute a member. Further, by eluting the resin by ultrasonic vibration, the decorative part 8 can be easily and efficiently fixed. Since the fixing portion 63a covers only a very small portion of the exposed portion 83, the appearance of the decorative part 8 is not impaired, and the design is also improved.

As shown in FIG. 13 , the accommodating portion 32 has a first groove 321 and a second groove 322 that is connected to the first groove 321 above the first groove 321 . A chain cloth 2b and a winding core 5b provided at the front end thereof are embedded under the fastener element 3b. The length of the chain cloth 2b embedded in the base portion 35 in the short side direction is preferably less than 50% of the maximum diameter of the accommodating portion 32. Further, it is preferable that the front end of the chain cloth 2b (the front end of the winding core 5b) is disposed away from the center of the accommodating portion 32. When the decorative component 8 shown in FIG. 5 is placed in the accommodating portion 32, the main body portion 81 is housed in the first groove 321 and the exposed portion 83 is housed in the second groove 322, and ultrasonic waves are applied to the decorative part 8. By vibrating, the resin constituting the base portion 35 is melted and protruded from the boundary portion between the first groove 321 and the second groove 322 (the side wall 34 of the second groove 322) to form a fixing portion covering a part of the decorative part 8 (not shown). ).

14 and 15 show an example in which the decorative part 8 is attached to the lower stopper 4. A housing portion 42 is disposed on the surface 400 of the lower stop 4 . As shown in FIG. 15 , the accommodating portion 42 has a first groove 421 and a second groove 422 that is connected to the first groove 421 above the first groove 421 . The chain fabrics 2a and 2b and the winding cores 5a and 5b provided at the front end thereof are embedded under the lower stopper 4. In the case shown in Fig. 15, it is preferable that the front ends of the chain fabrics 2a, 2b (the front end of the winding core 5a) are also disposed away from the center of the accommodating portion 42. When the decorative component 8 shown in FIG. 5 is placed in the accommodating portion 42, the main body portion 81 is housed in the first groove 421, and the exposed portion 83 is housed in the second groove 422, and the decorative part 8 and the lower portion are placed. Ultrasonic vibration is applied to the stopper 4, whereby the resin constituting the lower stopper 4 is melted and protruded from the boundary portion between the first groove 421 and the second groove 422 (near the side wall 44 of the second groove 422) to form the cover decorative part 8. A part of the fixed part (not shown).
