Technical field

The present invention relates to a slider used for a zipper of a garment such as sportswear or a bag such as a club bag, and more particularly to such a slider in which a pull tab made of elastic material is firmly attached to the slide on the main body of the block, and can prevent the pull-pan from wobbling and causing noise.

Background technique

Hitherto, there have been known pullpans for sliders of the above-mentioned type. An example 100 of this type of slider is shown in Japanese Utility Model Publication No. 62-27142 and is conveniently reproduced in Figure 17 of its accompanying drawings. This sliding block 100 is configured to prevent the pull tab 101 from accidentally swinging into a vertical position and becoming a hindrance. The slider body 102 of the slider 100 has a protruding ridge portion 104 formed longitudinally on an upper wing 103 thereof. A pair of end holes 106 are formed on opposite end surfaces of the protruding ridge portion 104 . An annular pull handle 108 is attached to the protruding spine portion 104 by inserting both ends of the handle 108 into the end holes. A protrusion 110 is provided on an opposite surface of the raised ridge portion 104 so as to protrude outwardly therefrom. When the pull handle 108 is laid flat relative to the upper surface of the upper wing 103 of the slider body 100, the pull handle 108 is adapted to engage with the protrusion 110 thereby preventing the pull handle 108 from being lifted and causing damage to the iron. Obstacles such as ironing clothes.

Another example of this type of slider is shown in Japanese Patent Unexamined Application No. 2002-209612 and is conveniently reproduced in Figure 18 of its drawings. In this slider 200, a tab 204 made of tough and elastic material is installed on the upper wing 202 of the slider body 201 in such a way that the tab 204 is normally pushed by its own displacement so that The vertical position presented on the upper wing 202 .

Therefore, the pull tab 204 is easy to be gripped, can absorb the shock caused when it collides with foreign objects, and can return to its original shape through its own elasticity.

In the slider shown in FIG. 17 , in order to keep the pull tab 101 in the flat position, it is necessary to equip the slider body 102 with a special mechanism to prevent the pull tab 101 from rising to the vertical position. It is difficult to provide such a mechanism on the slider main body 100 . On the other hand, in the slider 200 shown in FIG. 18, the pull tab 204 generally assumes a vertical position, but cannot be laid flat on the slider body 201, so there is a problem that the pull tab 204 creates an obstacle.

In view of the above-mentioned problems, an object of the present invention is to provide a slider for a slide fastener of a garment such as sportswear or a bag such as a bat bag, wherein the pull tab is made of a tough thermoplastic resin, a thermoplastic elastomer, etc. and rubber etc. are molded in the metal sliding block main body mold; the pull tab will not swing freely; the pull tab can be kept in the raised position or the lying position; the pull tab is prevented from contact with the slide block body or other Items contact and cause rattling noises; the pull tab will not shake or cause an unpleasant feeling to the wearer; and the pull tab will not be damaged.

Detailed ways

As shown in FIG. 1, a slider for a zipper according to the present invention includes a slider body 1 having a zipper tooth guide passage formed through itself for use as a passage along which the zipper teeth slide, and a slider body 1 pivotally connected to the slider. The pull tab 12 on the upper surface of the block main body 1 . The slider main body 1 is manufactured by die casting from zinc alloy or aluminum alloy. The slider body 1 comprises a pair of upper and lower wings 2 , 3 connected by guide posts 4 . A tab attachment portion or attachment protrusion 6 is mounted on the upper surface of the upper wing 2 . A through hole 7 is formed through the tab attachment protrusion 6 to let the shaft 14 of the tab 12 pass therethrough. This tab 12 can be produced by injection molding a tough soft material such as thermoplastic, thermoplastic elastomer or rubber directly on the slider body 1 . The tab 12 includes a shaft 14 inserted through a hole 7 formed by the tab attachment protrusion 6 mounted on the main body 1 and a tab body 13 connected to the opposite end of the shaft 14 to constitute a grip portion.

The outer circumferential surface 15 of the shaft 14 of the tab 12 and the inner circumferential surface of the hole 7 of the tab attachment protrusion 6 are in close contact. Therefore, when the shaft 14 rotates in the hole 7 , friction is generated between the outer peripheral surface 15 of the shaft 14 and the inner peripheral surface 8 of the hole 7 . After the pull tab is lifted into any appropriate position or brought into a flat position, this friction holds the pull tab 12 in these positions in a stable manner. Furthermore, a tab attachment protrusion 6 is mounted longitudinally on the slider body 1 and a hole 7 is formed longitudinally through the tab attachment protrusion 6 . The shaft 14 of the tab 12 is inserted into the hole 7 . Since the direction of the hole 7 and the shaft 14 is along the length of the slider main body 1 set to be larger than the width of the slider main body 1, the area where the outer peripheral surface 15 of the shaft 14 and the inner peripheral surface 8 of the hole 7 can contact each other The bigger they are, the more friction they can ensure.

In order to prevent the pull tab body 13 from contacting with the pull tab attachment protrusion 6 when the shaft 14 is rotated in the hole 7, the pull tab 12 has an opening 18 formed between the pull tab body 13 and the shaft 14. As shown in FIGS. 5 and 6, a raised inner peripheral edge 9 is protrudingly formed at the midpoint of the inner peripheral surface of the hole 7 of the tab attachment protrusion 6, and a circumferential groove 16 surrounds the shaft 14 of the tab 12. The outer peripheral surface 15 is formed to engage with the inner peripheral edge 9 of the hole 7 of the pull tab attachment protrusion 6 . Due to the engaged fit of the inner circumferential edge 9 and the circumferential groove 16 , the shaft 14 is prevented from sliding in the axial direction of the shaft 14 . Due to the above-mentioned structure, the pull tab 12 will not shake freely, and will not collide with other objects and cause rattling noises, thereby achieving a noise reduction effect.

A slider for a zipper is described according to a first embodiment of the invention shown in FIGS. 1 to 6 . The slider body 1 of the slider comprises a pair of upper and lower wings 2, 3 connected by guide posts 4, thereby defining a zipper tooth guide channel through which the zipper teeth pass. In order to guide the zipper teeth passing through the zipper element guide channel, the upper and lower wings 2, 3 have two pairs of upper and lower opposite flanges 5, 5 protrudingly formed on their respective opposite sides, and each upper flange 5 point to the corresponding lower flange 5. A tab attachment protrusion 6 in the shape of a square prism or a parallelepiped with a trapezoidal cross-section is mounted at the center of the upper surface of the upper wing 2 of the slider main body 1 throughout its length. A hole 7 of circular cross-section is formed longitudinally and centrally through the tab attachment protrusion 6 . As shown in FIGS. 3 , 5 and 6 , a raised inner peripheral edge 9 is protrudingly formed at the midpoint of the inner peripheral surface of the hole 7 . The cross-section of the inner peripheral edge 9 may be triangular or arcuate. The inner circumferential edge 9 extends continuously around the inner circumferential surface 8 of the hole 7 . The preferred height of the inner peripheral edge 9 is approximately between 0.3 mm and 0.5 mm. The slider main body 1 with the above structure is produced by die-casting process with zinc alloy or aluminum alloy.

The tab 12 is formed by directly injecting a tough thermoplastic material such as polyacetal, polyamide, polypropylene, or thermoplastic elastomer or rubber into the hole 7 of the tab attachment protrusion 6 of the molded slider body 1 are molded. The molded pull tab 12 thus comprises a shaft 14 inserted into the hole 7 and a pull tab body 13 integrally connected to the opposite end of the shaft 14 . The handle main body 13 constitutes a grip part. The pull tab body 13 and the pull tab attachment protrusion 6 define an opening 18 therebetween so that the pull tab 12 can be moved without causing any contact between the pull tab body 13 and the pull tab attachment protrusion 6. Turns on axis 14 in hole 7 of tab attachment protrusion 6 .

As shown in FIG. 2, when the pull tab main body 13 is held and lifted to a vertical position, due to the close and frictional contact between the outer peripheral surface 15 of the shaft 14 and the inner peripheral surface 8 of the hole 7, the pull tab The main body 13 is held upright. When the pull tab main body 13 is held and laid flat on the side of the slider main body 1 or in the horizontal direction, due to the frictional contact between the outer peripheral surface 15 of the shaft 14 and the inner peripheral surface 8 of the hole 7, the pull tab 13 can remain flat on the slider main body 1. Due to the frictional contact between the outer peripheral surface of the shaft 14 and the inner peripheral surface 8 of the hole 7, the pull tab main body 13 can not only maintain the vertical state and the horizontal state, but also maintain any position to which the shaft 14 can be rotated. For example, the pull tab body 13 may remain in an upwardly inclined position. Because the inner circumferential edge 9 formed on the midpoint of the hole 7 is fitted into the circumferential groove 16 formed on the midpoint of the shaft 14, the shaft 14 will not be in the longitudinal direction of the slider body 1 or the axis of the shaft 14. Move up. The pull tab main body 13 can be made into different shapes, such as flat plate, filament, B-shape, D-shape. Since the elongated tab attachment protrusion 6 is mounted on the slider main body 1 almost throughout its length, the tab 12 can be attached thereto in a stable manner, and moreover, the tab 12 can be attractively designed.

Sliders are used on zippers on garments and bags to attach or detach the zipper teeth of the zipper. In order to open or close the zipper; first, hold and lift the pull tab body 13 of the pull tab 12 . Then, the slider main body 1 moves along the zipper in the direction of opening or closing, while the handle main body 13 is still kept lifted. The pull tab 12 can remain raised after the zipper has been opened or closed. Alternatively, the pull tab 12 can be laid flat on the slider body 1 by rotating the shaft 14 and kept flat; otherwise, the pull tab 12 may constitute an obstacle. Since the pull tab 12 maintains a stable position on the slider body 1 and never dangles or swings on the slider body 1, the pull tab 12 is completely prevented from bumping against external objects and causing rattling noises. Furthermore, the pull tab 12 is elastic and pleasant to the touch because it is made of a soft material. Furthermore, the pull tab 12 will not damage itself or other adjacent things.

Fig. 7 shows a first modification of the slider according to the first embodiment of the present invention. This modification is substantially the same as the first embodiment except that the hole 7 does not have an inner circumferential edge formed therein and the shaft 14 does not have a circumferential groove. Instead, the shaft 14 inserted through the hole 7 is made to have a diameter outside the hole 7 that is larger than the diameter inside the hole 7, thereby forming a circumferential step 17 on opposite sides of the hole 7, thereby preventing the tab 12 from slipping. The shaft 14 moves in the axial direction of the hole 7 .

Fig. 8 shows a second modification of the slider according to the first embodiment of the present invention. Also from the comparison of FIGS. 3 , 7 and 8 , the second modification shown in FIG. 8 is equal to the combination of the first embodiment shown in FIG. 3 and its first modification shown in FIG. 7 . In other words, the hole 7 has an inner peripheral edge 9 protrudingly formed on the midpoint of its inner peripheral surface 8 and the shaft 14 has a peripheral groove 16 formed on its midpoint for engaging fit with the inner edge 9 of the hole 7 . In addition, the shaft 14 is made such that the diameter outside the hole 7 is larger than the diameter inside the hole, so that a circumferential step 17 is formed on opposite sides of the hole 7 . As a result, the shaft 14 of the tab 12 is more reliably prevented from axial movement through the hole 7 by its circumferential step 17 and circumferential groove 16 .

Fig. 9 shows a third modification of the slider according to the first embodiment of the present invention. The third modification is substantially identical to the first embodiment, except that a hole 7 of square cross section is formed in the longitudinal direction of the tab attachment protrusion 6 instead of the hole 7 of circular cross section, correspondingly molded in the hole 7 of square cross section The shaft 14 of the pull tab 12 is in the shape of a square prism, so the shaft 14 cannot rotate in the hole 7 . The outer circumferential surface 15 of the shaft 14 of the tab 12 is in close contact with the inner circumferential surface 8 of the hole 7 of the tab attachment protrusion 6 . The handle 12 is usually placed horizontally by its own elasticity. In use, the pull tab 12 is gripped and lifted against its own elasticity to open or close the zipper as shown in dashed lines. Once the pull tab 12 is released after the opening or closing operation is completed, the pull tab main body 13 returns to the horizontal state by its own elasticity. In this way, the pull tab 12 will not constitute an obstacle. Furthermore, the pull tab 12 will not wobble and thus will not create rattling noises. Whether or not an inner peripheral edge is formed on the midpoint of the inner peripheral surface of the hole 7 is optional in this variant.

10 to 12 show sliders of a slide fastener according to a second embodiment of the present invention. The tab attachment portion 6 is provided on the upper wing 2 of the slider body 1 so as to extend laterally across its entire width and to be highest in the middle of its length. A hole 7 of circular cross-section is formed through the middle of the handle attachment portion 6 so as to extend in the lateral direction of the slider main body 1 . The pull tab 12 includes a pull tab body 13 in the shape of a segment and a shaft 14 integrally formed with opposite ends of the pull tab body 13 . The tab 12 is made by injection molding a soft material into the hole 7 formed through the tab attachment portion 6 . Instead of being arcuate, the molded pull tab body 13 could be rectangular or disc or any other shape.

The pull tab 12 has an opening 18 defined between the pull tab body 13 and the shaft 14 to prevent the pull tab body 13 from contacting the slider body 1 when the pull tab 12 pivots in the longitudinal reciprocating direction of the slider body 1 . Like the previous embodiments, the inner peripheral surface 8 of the hole 7 is in close and frictional contact with the outer peripheral surface 15 of the shaft 14 in this embodiment. After the pull tab body 13 of the pull tab 12 is grasped and lifted to a vertical state or laid flat to a horizontal state, once it is released, the pull tab 12 stays in that state due to the aforementioned frictional contact.

Fig. 13 shows the slide block of the slide fastener according to the third embodiment of the present invention. This slider is different from that of the previous embodiment in that instead of a separate tab attachment protrusion 6 provided on the upper surface of the slider main body 1, a pair of tab attachment protrusions 6a, 6b are installed on both sides of the upper surface of the upper wing 2 facing each other. The tab attachment tabs 6a, 6b each have a circular hole 7a, 7b formed through itself in alignment with each other. The tab 12 is made by injection molding a soft material between opposing tab attachment projections 6a, 6b. The pull tab 12 includes a pull tab body 13 and a shaft 14 formed on a proximal end of the pull tab body 13 . The shaft 14 protrudes laterally to opposite sides of the pull tab main body 13 . The shaft 14 is threaded into the holes 7a, 7b of the tab attachment protrusions 6a, 6b. The handle 12 can be lifted vertically or horizontally.

Fig. 14 shows a modification of the slider of the slide fastener according to the third embodiment of the present invention. This variant differs from the third embodiment in that the pull tab is made by molding a soft material through the holes 7a, 7b of the pull tab attachment projections 6a, 6b in such a way that , the opposite ends of the shaft 14 extend to the other side of the holes 7a, 7b and are bent upwards and connected to the pull tab body 13, thereby forming a pair of opposing through holes 19a, 19b in the pull tab body 18. The opposing perforations 19 a , 19 b serve to prevent the tab 12 from coming into contact with the tab attachment protrusion 6 when the tab 12 pivots reciprocally in the longitudinal direction of the slider main body 1 . With this structure, after the pull tab main body 13 is reciprocated in the longitudinal direction of the slider main body 1 in the holes 7a, 7b, the pull tab main body 13 can be held at any position.

Fig. 15 shows the slide block of the slide fastener according to the fourth embodiment of the present invention. This slider is structurally different from all the embodiments and their variants described above in that there is no hole in the tab attachment protrusion 6 and no shaft 14 on the tab 12 . Instead, there is a shaft 14 on the tab attachment protrusion 6 and a hole in the tab 12 . Specifically, the tab attachment protrusion 6 in the shape of a square prism is installed centrally and longitudinally on the upper surface of the upper wing 2 of the slider main body 1 . The tab attachment protrusion 6 has a pair of shafts 14 formed on opposite sides near the distal end thereof and arranged to be aligned with each other. The pull tab 12 is molded onto the slider body 1 by molding a soft material around the shaft 14 . The pull tab 12 thus molded comprises a pull tab main body 13, a pair of arms 20a, 20b extending along opposite sides of the pull tab main body 13 and from its proximal end, and an arm 20b defined between the pull tab main body 13 and the opposite arm 20a. , 20b between the cutout 21. The arms 20a, 20b each have a perforation 7a, 7b through itself and arranged in alignment with each other. The shafts 14a, 14b of the tab attachment protrusions 6 are inserted into the respective through-holes 7a, 7b of the tab 12 . The arms 20a, 20b of the pull tab 12 are thickened so that the pull tab 12 can be easily lifted and laid flat horizontally. Whether the circumferential edge 9 or the circumferential groove 16 is formed on the hole 7 or the shaft 14 is optional in this embodiment.

Fig. 16 shows a modification of the slider of the slide fastener according to the fourth embodiment of the present invention. This variant is substantially the same as the fourth embodiment, except that instead of the perforations 7a, 7b; the arms 20a, 20b have opposing and aligned blind holes 7c, 7d formed through themselves. The blind holes 7c, 7d are formed in the pull tab 12 by molding a soft material onto the shafts 14a, 14b so as to completely surround the shafts 14a, 14b. Since the shafts 14a, 14b of the tab attachment protrusion 6 are inserted through the respective blind holes 7c, 7d of the tab 12, the tab 12 is more firmly attached to the tab attachment protrusion 6, so that the tab 12 can be easily ground is lifted and laid flat.

Conclusions, categorization, and scope:

In the slider of the slide fastener according to the present invention, the slider main body is made of zinc alloy or aluminum alloy through a die-casting process. A soft material such as a malleable thermoplastic resin or thermoplastic elastomer or synthetic rubber is injection molded directly onto the slider body to attach the tab to the slider body.
