Description
- The entire disclosure of Japanese patent application number 2003-388723 filed on Nov. 19, 2003 and Japanese patent application number 2003-390739 filed on Nov. 20, 2003 are incorporated herein by reference in their entirety.
- 1. Field of Invention
- This invention relates to a slider for a slide fastener, and particularly to a slider for a slide fastener wherein a pull tab can be pivotally and rotatably moved on the upper wing of its slider body and the pull tab can be replaced at ease, and which is provided with a simple mechanism to prevent or decrease rattling noises caused by the pull tab striking on the slider body when one jogs in a sport wear bearing the slider.
- 2. Background of the Invention
- Heretofore, there have been sliders of the pull-tab-rotatable type wherein the pull tab can be pivotally and rotatably moved on an upper wing of a slider body. One example is shown in Japanese Utility Model Publication No. 7-46168 and also reproduced in
FIG. 18 of the drawings appended hereto for convenience sake. Theslider body 100 of this slider has amounting hole 108 formed vertically through the diamond orguidepost 106. Themounting hole 108 terminates at its lower end in a flared recess (not shown) formed in thelower wing 104 of theslider body 100 and terminates at its upper end in a steppedcountersink 110, which includes a large-diameteredupper bore 110 a and a small-diameteredlower bore 110 b. The large-diameteredupper bore 110 a is adapted to receive part of acircular disk 116 and the small-diameteredlower bore 110 b is adapted to receive part of aretaining member 120. Thecircular disk 116 has a throughhole 117 formed centrally therethrough. Theretaining member 120 has an enlargedhead 122, acircular body 124 and acylindrical leg 126 stacked concentrically one beneath another so as to extend downwardly in a stepped manner. Apull tab 130 has a proximal end bifurcated to provide a pair ofattachment lugs 132, which hasrespective pintles 134 formed in alignment with each other. Thepintles 134 of thepull tab 130 are pivotally attached to the diametricallyopposite recesses 118 formed on the opposed sides of thecircular disk 116. Then, thecircular disk 116 is rotatably mounted on theslider body 100 in the large-diameteredupper bore 110 a. Then, thecylindrical leg 126 of theretaining member 120 is inserted through themounting hole 108 and is clinched to theslider body 100 by flattening the end of thecylindrical leg 126 in the flared recess, so that the retainingmember 120 clamp theslider body 100 between itscircular body 124 and its flattened end of theleg 126 with thecircular disk 116 interposed between theslider body 100 and the enlargedhead 122 of theretaining member 120. Consequently, thepull tab 130 can be moved pivotally and rotatably relative to theslider body 100. - The slider shown in
FIG. 18 is of the type that thepull tab 130 is movable both pivotally and rotatably relative to theslider body 100, indeed. However, in case that thepull tab 130 is broken or the wearer desires to replace the pull tab for any other reasons, he or she cannot replace it. There is a great difficulty to replace thepull tab 130, since theleg 126 of theretaining member 120 has its lower end clinched in the flared recess formed in thelower wing 104 of theslider body 100. If the wearer wishes to replace thepull tab 130, then, the slider as a whole must be replaced. In order to remove the slider from the slide fastener chain used in an article, first, an upper end stop must be removed and then the slider must be pulled off the slide fastener chain. Thereafter a new slider must be inserted in to the fastener chain and an upper end stop must be attached thereto. The replacing operation is thus tedious and time-consuming. - Furthermore, since in this type of sliders, a pull tab can be both pivotally and rotatably moved on the slider body; when one do an exercise, such as jogging in a sport wear bearing the slide fastener, the more the pull tab of the slider jolts and strikes against the slider body, disadvantageously causing rattling noises. Such rattling noises give much offence to the ear of the wearer. Moreover, when one walks with a bag along, the pull tab also strikes on the slider body, causing annoying rattling noises. Some methods of preventing or decreasing such rattling noises were adopted before.
- One of the conventional methods is shown in U.S. Pat. No. 5,101,538 and is conveniently re-produced in
FIG. 19 . As shown inFIG. 19 , acylindrical fixing section 202 is provided on one end of arectangular coupling 201 which is pivotally mounted on alocking arm 204 of aslider body 206. An annularresilient member 210 is molded to thecylindrical fixing section 202 through injecting molding, thus to provide apull tab 200. Thefree end 209 of the annularresilient member 210 is normally biased by the resiliency of the annularresilient member 210 itself againstfastener elements 208 or fabric strips of the sport wear to which the slide fastener is attached. This prevents thepull tab 200 from jolting and causing rattling noises. - Another method is shown in Japanese Patent Laid-open application No. 2001-204514 and is also conveniently reproduced in
FIG. 20 . Acover 300 made of metal or plastics is fit to a pull tab 302 of aslider 304 reciprocally mounted along theslide fastener 306. Thecover 300 has alocking member 308 in the form of a circular hole formed on the free end thereof. The sport wear has alocking plate 310 mounted on the fabric piece of its front part. Thelocking plate 310 has alocking projection 312 formed thereon. When theslide fastener 306 is closed, thelocking member 308 of thecover 300 is adapted to come into locking engagement with thelocking projection 312 of thelocking plate 310, which prevent the pull tab 302 from jolting and hence causing rattling noises. - The
slider 206 of the slide fastener shown inFIG. 19 is complex in construction and requires aspecial pull tab 200. Therefore, the manufacturing cost is very high. It is difficult to supply thisslider 206 at a lower price. - In the
slider 304 of the slide fastener shown inFIG. 20 , in order to prevent rattling noises of the pull tab 302, it is necessary to slide theslider 304 all the way up to the end of the slide fastener and to bring thelocking member 308 of thecover 300 into locking engagement with thelocking projection 312 of thelocking plate 310, while staring thelocking member 308 and thelocking projection 312 very attentively, which is very tedious. When the pull tab 302 is not locked to thelocking projection 312 of thelocking plate 310, or when pull tab 302 stops in the middle of theslide fastener chain 306, theattachment link 307 of the pull tab 302 which remains uncovered tends to strike against theslider body 305, causing rattling noises. So, as mentioned above, it is absolutely necessary to slide theslider 304 all the way up to the end of theslide fastener 306 and to bring thelocking member 308 of thecover 300 into locking engagement with thelocking projection 312 of thelocking plate 310, which is very tedious. - In view of the drawbacks set forth above, the present invention has a its object to provide a slider for a slide fastener of the type that a pull tab is pivotably and rotatably connected to the slider body, which has a simple mechanism whereby only the pull tab can be replaced at great ease, even when the slider is used in the slide fastener attached to an article; if the pull tab is broken or the wearer wishes to replace the pull tab.
- Another object of the present invention is to provide double sliders for a slide fastener wherein a pair of sliders are reciprocally mounted on a single fastener chain and disposed reversely to each other, the pull tabs of the two sliders can be locked by a locking means reliably and easily.
- Still another object of the present invention is to provide a slider for a slide fastener which has a pull tab pivotably and rotatably connected to the slider body and which has means for preventing or decreasing rattling noises caused by the pull tab striking against the slider body, thus accomplishing muffling effects simply and less costly.
- Yet another object of the present invention is to provide double sliders for slide fasteners wherein a pair of sliders are reciprocally mounted on a single fastener chain and disposed reversely to each other, the pull tabs of the two sliders can be locked by a locking means reliably and easily and each slider has means for preventing or decreasing rattling noises caused by the pull tabs striking each other or each pull tab striking against the respective slider body, thus accomplishing muffling effects simply and less costly.

- Description is now made on a
slider 1 for a slide fastener according to the first embodiment of the present invention shown inFIGS. 1 through 5 of the drawings appended hereto. - According to the present invention, broadly, a
slider 1 is comprised of four parts, that is, aslider body 2, apull tab 3, an attachingpole 4 and apin 5. These parts are all made of metal. Theslider body 2 comprises anupper wing 10 and alower wing 11 joined at their fronts by aguidepost 12. A mountinghole 13 is formed vertically through theguidepost 12 to receive the attachingpole 4 therethrough. An upper and alower countersink 14 are formed at the upper and lower ends, respectively, of the mountinghole 13. A raisedrim 15 is formed around thecountersink 14 on each of the outer surfaces of the upper andlower wing pull tab 3 attached to the attachingpole 4 contacts theslider body 2 on only the raisedrim 15 or a little contacting surface and hence incurs a little frictional resistance, so that thepull tab 3 can be moved pivotally and rotatably relative to theslider body 2 smoothly. - The
pull tab 3 includes agrip portion 29 as a major portion and a pair of opposed attachment lugs 25 formed by bifurcating the proximal end of thepull tab 3 and adapted to be attached to the attachingpole 4. A pair ofpin apertures 26 are formed through the respective attachinglugs 25 and disposed in alignment with each other. The pin apertures 26 are slightly greater in diameter than thepin 5 in order to let thepin 5 threthrough. As viewed in the profile, thepull tab 3 is bent obtusely at abent portion 27 which is adjacent to the attachment lugs 25. As a result, thepull tab 3 attached to the attachingpole 4 can either contact on or stay float above the front surface of the article such as clothing or bags to which the slide fastener is attached, so that thepull tab 3 can be advantageously arranged on the article in stably and sightly, and further thepull tab 3 can be griped very easily. - The attaching
pole 4 is cylindrical and is provided at its lower end with a large-diametered portion 20 which is adapted to fit into thelower countersink 14. Apin aperture 21 is formed laterally through the attachingpole 4 adjacent its upper end and is adapted to have thepull tab 3 pivotally mounted thereon. Thepin hole 21 is narrowed at its middle to provide a narrowedportion 22 in the form of an inner peripheral projection projecting inwardly in order to firmly fasten thepin 15 therein. Thepin 6 is cylindrical but has a wave-like slit 31 formed longitudinally throughout its length so as to impart resiliency to thepin 5. Such apin 5 is commonly called as a spring pin. - In order to assemble the
slider 1, first, the attachingpole 4 is inserted through the mountinghole 13 formed through theguidepost 12 of theslider body 2 from its lower end, until the large-dimatered portion 20 of the attachingpole 4 fits into thecountersink 14 and thepin hole 21 of the attachingpole 4 comes up beyond the upper surface of theslider body 2. Then, thepin hole 21 of the attachingpole 4 and thepin apertures 26 of the opposed attachment lugs 25 of thepull tab 3 are brought into alignment with each other. With thepin hole 21 and thepin apertures 26 kept in alignment, thepin 5 is forced into thepin aperture 26 of the attachment lugs 25 of thepull tab 3 and then thepin hole 21 of the attachingpole 4 against the resiliency of thepin 5, so that thepin 5 is secured to the narrowedportion 22 of thepin hole 21 by its own resiliency and the assemblage of theslider 1 has been carried out. - In order to replace the
pull tab 3 when thepull tab 3 is broken or the wearer desires to replace it for other reasons, thepin 5 is pulled off thepin apertures 26 of the attachment lugs 25 of thepull tab 3 and the narrowedportion 22 of thepin hole 21 of the attachingpole 4 against resiliency of thepin 5. Then, thepull tab 3 is removed from theslider body 2. Lastly, a new pull tab is attached to the attachingpole 4 in the way mentioned earlier. - As shown in
FIG. 1 , as mentioned earlier, theslider 1 is comprised of four parts, that is, theslider body 2, thepull tab 3, the attachingpole 4 and thepin 5. Theslider body 3, thepull tab 4 and the attachingpole 4 are made of hard materials. They are die-casted from metals such as zinc alloy, aluminum alloy, or are injection molded from hard plastics such as polyacetal, polyamide, polypropylene, polybutylene terephthalate. Theslider body 2 is comprised of an upper andlower wings guidepost 12. A pair ofguide flanges 17 are provided one on each side edge of theupper wing 10 to define with the guide post 12 a Y-shapedguide channel 16 to guidefastener elements 7 therethrogh. The attachinghole 13 of a circular cross-section is formed vertically through theguidepost 4. The mountingpole 4 is inserted through the attachinghole 13 As shown inFIG. 3 , the upper andlower countersinks 14 are formed in the upper and lower ends of the attachinghole 13, respectively. As shown inFIG. 4 , as mentioned above, the raisedrims 15 are formed on the outer surfaces of the upper andlower wing countersinks 14. The raisedrim 15 is adapted to come into sliding contact with the tips of the attachment lugs 25 of thepull tab 3, when thepull tab 3 is pivoted or rotated on the slider body. - As shown in
FIG. 1 , Thepull tab 3 includes agrip portion 29 as a major portion and a pair of opposed attachment lugs 25 formed by bifurcating the proximal end of thepull tab 3. The two attaching lugs 24 have therespective pin apertures 26 formed therethrough, whichpin apertures 26 are in alignment with each other. The pin apertures 26 are greater in diameter than thepin 5 in order to let thepin 5 threthrough. Furthermore, thepin apertures 26 are formed greater in diameter than thepin hole 21 formed through the attachingpole 4. As view in the profile, thegrip portion 29 of thepull tab 3 is bent obtusely at abent portion 27 adjacent to the attachment lugs 25. A circular throughhole 28 is formed through thegrip portion 29 adjacent to the distal end. - As further shown in
FIG. 1 , the attachingpole 4 designed to attach thepull tab 3 thereto is cylindrical as a whole and has a large-diametered portion 20 formed at its lower end so as to spread radially therefrom. The large-diametered portion 20 is adapted to fit to thecountersink 14 of theslider body 2. The attachingpole 4 has thepin hole 21 formed through its upper end and designed to pivotally mount thepull tab 3 thereon. Thepin hole 21 has a narrowedportion 22 formed at its middle in the shape of aninner projection 22 projecting inward from its inner surface, so as to fasten the insertedpin 15 through its resiliency The narrowedportion 22 may be in the form of a U-cross-sectioned projection or a convex cross-sectioned projection as shown inFIG. 5 . The narrowedportion 22 may be of any cross-sectional form as far as it can function to fasten thepin 5 thereto. - The
pin 5 may be of any shape that permits thepin 5 to be inserted into thepin hole 21 and firmly clamped by the narrowedportion 22 thereof. So, thepin 5 may be either solid or hollow like a pipe. The most preferred construction of thepin 5 is a hollow cylinder or pipe which has a wave-like groove formed axially thereof in order to impart resiliency to thepin 5, so that thepin 5 can be readily inserted through the narrowedportion 22 of thepin hole 21 and thereafter thepin 5 can be firmly clamped in the narrowedportion 22 through resiliency of thepin 5. - For assemblage of this
slider 1, first, the cylindrical attachingpole 4 is inserted upwardly through the circular mountinghole 13 formed through theguidepost 12 of theslider body 2 until the large-diametered portion 20 of the attachingpole 4 fit into thecountersink 14, whereupon the attachingpole 4 is rotatably mounted on theslider body 2. Then, thepin apertures 26 formed through the attachinglugs 25 are brought into registry with thepin hole 21 of the attachingpole 4 lying beyond the upper surface of theslider body 2. Then, thepin 5 is forced through thepin apertures 26 and thepin hole 21 so that thepin 5 passes through the narrowedportion 22 of thepin hole 21 by contracting its diameter against its resiliency and then get clamped by the narrowedportion 22 through resiliency of thepin 5. Consequently, thepin 5 itself is fastened to themounting pole 4, but thepull tab 3 is pivoted back and forth on thepin 5. In addition, since the attachingpole 4 is rotatably mounted on the slider body 2), thepull tab 3 can be rotate horizontally on theslider body 2 in free manner with the tips of the attachinglugs 25 sliding on the raisedrim 15. - As shown in
FIG. 2 , theslider 1 according to the invention is assembled with aslide fastener chain 6 to provide a slide fastener. The thus assembled slide fastener is then sewn to an article, such as clothing or bags. When thepull tab 3 is broken or the wearer wishes to replace thepull tab 3 in the slide fastener incorporated in the article, the wearer can dismantle thepull tab 3 by merely removing thepin 5 from thepin aperture 26 of thepull tab 3 andpin hole 21 of the attachingpole 4. Then, anew pull tab 3 can be attached to the attachingpole 4. - A slide fastener slider according to the second embodiment of the present invention shown in
FIG. 6 is designed for use with a slide fastener chain of the type wherein fastener element rows are sewn to the rear surface of its fastener tapes. Unlike theslider 1 according to the first embodiment, thisslider 1 has a pair ofguide flanges 17 formed on alower wing 11 of itsslider body 2 to guide thefastener elements 7. The mountinghole 13 has the same shape in its upper part and its lower part, as in the case of the first embodiment. As well seen from comparison ofFIGS. 3 and 6 , the assemblage of theslider 1 according to the second embodiment is identical with that according to the first embodiment with the only exception that theslider body 2 has been placed upside down. The attachingpole 4 is first inserted upwardly through the mountinghole 13. The pin apertures 26 of the attachinglugs 25 are brought into registry with thepin hole 21 of the attachingpole 4. Then, thepin 5 is forced through the pin apertures 216 and thepin hole 21 so that thepin 5 is releasably attacked to the attachingpole 4. -
FIG. 7 shows aslide fastener slider 1 according to the third embodiment of the present invention. In thisslider 1, the mountinghole 13 is of the shape of a truncated cone with a larger-diametered portion disposed at its bottom. A raisedrim 15 is formed around the mountinghole 13 on only the upper surface of theslider body 2. The attachingpole 4 is also of the shape of a truncated cone as a whole. Since the mountinghole 13 is of a truncated cone, and the attachingpole 4 is of a complementarily truncated cone, the attachingpole 4 can be mounted on theslider body 9 in very stable manner so that the attachingpole 4 can be rotated on theslider body 2 very smoothly. The attachingpole 4 has apin hole 21 formed laterally therethrough at its upper end for housing apin 5 therethrough. As viewed in profile, thepull tab 3 as a whole (including the attachment lugs 25) is formed straight, unlike the one according to the preceding embodiments. The pin apertures 26 of the attachinglugs 25 are brought into registry with thepin hole 21 of the attachingpole 4 lying beyond the upper surface of theslider body 2. Then, thepin 5 is forced through thepin apertures 26 and thepin hole 21. It is readily seen that, unlike theslider body 2 according to the preceding embodiments, theslider body 2 according to the third embodiment is unidirectional, that is, theslider body 2 can allow the attachingpole 4 to fit into its mountinghole 13 when disposed in only one direction, in other words, the attachingpole 4 cannot fit into the mountinghole 13, if theslider body 2 is disposed upside down. -
FIG. 8 shows a slide fastener slider according to the fourth embodiment of this invention. The slider according to the fourth embodiment is substantially identical with the slider according to the first embodiment except that the attachinghole 13 has acountersink 14 formed at its lower end alone. -
FIG. 9 shows aslide fastener slider 1 according to the fifth embodiment of this invention. Thisslider 1 has a simplecylindrical mounting hole 13 with a uniform diameter throughout its length formed through theguidepost 12 of theslider body 2. The attachingpole 4 is substantially of a simple cylindrical shape and has a large-diametered portion 20 in the shape of a thin disk integrally formed at the lower end thereof. The large-diametered portion 20 is flat at its inner and outer surfaces. The large-diametered portion 20 is adapted to intimately contact the lower surface of theslider body 2. Instead of the large-diametered portion 20 integrally formed with the attachingpole 4, the pole body of the attachingpole 4 and thelarge diametered portion 20 may be formed as separate parts. For example, the lower end of the pole body of the cylindrical attachingpole 4 is provided with an internal thread and the large-diametered portion 20 has a correspondingly threaded shank formed centrally of the upper surface thereof. The threaded shank of thelarge diametered portion 20 is screwed with the internal thread of the pole body of the cylindrical attachingpole 4, thus provide the attachingpole 4. -
FIGS. 10 and 11 showdouble sliders 1 for a slide fastener according to the sixth embodiment of this invention. In this embodiment, the twosliders 1 are reciprocally mounted on a singleslide fastener chain 6 and disposed reversely to each other. One of the twosliders 1 according to this embodiment (the left one as viewed inFIG. 10 ) is identical with theslider 1 according to the first embodiment but the right one differs therefrom in that thepull tab 3 is bent at thebent portion 27 reversely to thepull tab 3 of theslider 1 according to the first embodiment. Since onepull tab 3 is bent reversely to theother pull tab 3; when bothsliders 3 are brought into abutting engagement with their respective front ends contacted with each other to close theslide fastener chain 6 as shown inFIG. 11 and onepull tab 3 is turned over against the other, onepull tab 3 can be laid flatly over the other. As shown inFIG. 11 , after onepull tab 3 is laid flatly over the other with their respective circular throughholes 28 in registry with each other, ashackle 35 of apadlock 34 is inserted through the circular throughholes 28 of thepull tabs 3 of bothsliders 1 and locked. Bothpull tabs 3 being reversely bent at thebent portion 27 permits onepull tab 3 to be laid flatly theother pull tab 3 when the former is turned against the latter. This facilitates the insertion of the locking of theshackle 35 of thepadlock 34. -
FIGS. 12 through 16 shows aslide fastener slider 1 according to the seventh embodiment of the present invention. Theslider 1 according to the seventh embodiment is substantially identical with theslider 1 according to the first embodiment except that thepull tab 3 has a shock-absorbingmember 50 mounted in its region where thegrip portion 20 of thepull tab 3 contacts theslider body 3, when thepull tab 3 is pivoted or rotated on theslider body 2. The shock-absorbingmember 50 is made of soft materials, such as polyurethane, silicon rubber, thermoplastic elastomer, and other soft plastics, which are softer than the materials of theslider body 2 and thepull tab 3, so that theshock absorbing member 50 functions to absorb the shock caused by collision of thepull tab 3 and theslider body 2, thus prevent rattling noises from getting caused. - In order to mount the shock-absorbing
member 50 on thepull tab 3; as shown inFIG. 15 , first, a pair ofrecesses 52 of a certain area are formed one on each side of thegrip portion 29 of thepull tab 3 at the region where thepull tab 3 is likely to contact theslider body 2. A plurality of small throughholes 53 are formed through thegrip portion 29 of thepull tab 4 within therecesses 52. Then, the shock-absorbingmember 50 is injection-molded from soft plastic within therecesses 52 so as to fill up therecesses 52 and swell or bulge on both upper and lower surfaces of thepull tab 4. As shown inFIG. 5 , the upper and lower parts of the shock-absorbingmember 50 are joined through the small throughholes 53. Since the shock-absorbingmember 50 is embedded in therecesses 52 and will never get caught by extraneous things and the upper and lower parts of the shock-absorbingmember 50 are joined through the small throughholes 53; the shock-absorbingmember 50 will never be dislodged from thepull tab 3. Therefore, the shock-absorbingmember 50 endures a long use and enjoys excellent muffling effects. - As better shown in
FIG. 13 , thepull tab 4 has the shock-absorbingmember 50 mounted in its region where thegrip portion 29 of thepull tab 3 contacts theslider body 3 when thepull tab 3 rotates and pivots theslider body 2. Specifically, as shown inFIG. 15 , the twoelliptical recesses 52 are formed one of each side of thegrip portion 29 of thepull tab 3 between the attachment lugs 25 and the throughhole 28 formed at the distal end of thegrip portion 29. A plurality of small through holes 53 (two circular holes and one oblong hole disposed therebetween shown here) are formed through thegrip portion 29 within therecesses 52. As better shown inFIG. 16 , the shock-absorbingmember 50 is injection-molded from soft plastics on the both sides of thegrip portion 29 so as to fill up therecesses 22 and swell or bulge on both sides of thepull tab 3. The upper and the lower parts of theshock absorbing member 50 are connected through the small throughholes 53 formed within therecesses 52, so that the shock-absorbingmember 50 is firmly mounted on thepull tab 3 against dislodgment. The shock-absorbingmember 50 has a plurality ofgrooves 59 formed in the upper and lower sides thereof so as to extend laterally of the length of thepull tab 3. Thesegrooves 59 are intended to facilitate gripping of the shock-absorbingmember 50 and hence thegrip portion 29 of thepull tab 3. - When the
pull tab 3 rotates and pivots on theslider body 2, the fact that the shock-absorbingmember 50 exists in the region where thepull tab 3 contacts theslider body 2 matters. Even if thepull tab 3 strikes heavily upon theslider body 2, the shock-absorbingmember 50 advantageously prevents rattling noises from being caused or absorbs the rattling noises, thus achieving muffling effects. -
FIG. 17 showsdouble sliders 1 for a slide fastener according to the eighth embodiment of this invention. Thedouble sliders 1 according to the eight embodiment are substantially identical with thedouble sliders 1 according to the sixth embodiment except that the twosliders 1 have shock-absorbingmembers 50 mounted on theirrespective pull tabs 3, as better seen from comparison ofFIGS. 11 and 17 . - As shown in
FIG. 17 , the twosliders 1 are brought into abutting engagement with each other with their respective front ends contacted with each other in order to close theslide fastener chain 6, and one of thepull tabs 3 is turned over against the other with their respective throughholes 28 in registry with each other. Then, theshackle 35 of thepadlock 34 is inserted through the throughholes 28 of thepull tabs 3 and locked. Since thepull tabs 3 of the twosliders 1 are locked with the respective shock-absorbingmembers 50 interposed therebetween, the shock-absorbingmembers 50 of bothpull tabs 3 prevent thepull tabs 3 from striking directly against each other and causing rattling noises, thus accomplishing muffling effects. In addition, theshock absorbing member 50 of eachpull tab 3 prevents therespective pull tab 3 from directly striking against itsrespective slider body 2 and causing rattling noises, as well. - With this construction of the present invention, even after the slide fastener is incorporated in a certain article such as clothing or bags, only the pull tab can be advantageously replaced at great ease without the fastener chain left intact.
- Since the shapes of the mounting hole and the attaching pole are both very simple in construction, the manufacture and assemblage of the parts can be made at ease.
- Even if the
pull tab 3 contacts theslider body 2 during operation or by vibration of the slide fastener, the shock-absorbingmember 50 always goes between thepull tab 3 and theslider body 2, thus absorbing or decreasing rattling noises, thus accomplishing muffling effects with a simple mechanism. - A slider according to the present invention is mounted on a slide fastener used for various kinds of articles such as clothing, bags, cases. Even when the slide fastener has been incorporated in such articles, a pull tab can be replaced at great ease. This slider can be also used in a so-called double-slider type slide fastener wherein two sliders are reciprocally mounted on a single fastener chain and disposed reversely to each other. After the fastener is closed, the pull tabs of both sliders can be locked by a shackle of a padlock.
- If equipped with a smaller pull tab, a slider according to the present invention is suitable for use on sport wares, personal belongings, small bags, small cases or the like. If quipped with a bigger pull tab, it is suitable for use on a shoulder bag or the like. Furthermore, a pull tab in rectangular shape can be used on an auto-locking type slider.
- Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Many other variations are possible.
- Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
