A slider for a slide fastener in which the slider is attached to fastener chains is provided. The slider includes a first member and a second member. The first member includes an upper blade, a lower blade, a guide post connected between the upper blade and the lower blade, and a connecting post protruding from the upper blade. The second member includes a first arm and a second arm separated from each other, is attached to the first member by the first arm and the second arm, and is configured to rotate along an upper-lower direction relative to the first member and around a fulcrum provided on the upper blade or the lower blade. The first member or the second member is provided with a flange. Three or more fit sections are formed between the first member and the second member.

Slider and slider assembling method

A slider for slide fastener includes: a body including a pull tab attachment post; and a pull tab. The pull tab includes: a coupling member including an exposed portion and an embedded portion; and a pinching member including a first pinching portion including an annular end portion having an opening through which the embedded portion is to be inserted, and a second pinching portion provided to the first pinching portion with the embedded portion interposed therebetween. At least one of a front end surface and a rear end surface of the pull tab attachment post has a protrusion. And when the pull tab is tilted toward at least one of a front side and a rear side of the body, the protrusion locks the pull tab to restrict rotation of the pull tab.

Slider for slide fastener and method for manufacturing slider for slide fastener

A slider for a slide fastener useable with a slider with an automatic stop function to secure a tab to enable automatic engagement and prevent swinging of the tab, regardless of the type of tab, when the tab is tilted to an engaged portion side. An engaging portion is formed in an attachment hole of the tab. An engaged portion is formed in the slider body or the tab attachment part. When the tab is tilted to be almost parallel to an upper blade on the engaged portion side of the tab attachment part, due to a biasing force of the spring member, the lock pin moves the shaft portion of the tab downward and to an opposite side of a tilted direction, and a tip portion of the engaging portion of the tab is pulled into to be engaged with the engaged portion side of the tab attachment part.

Slider for slide fastener

There is provided a slider for a slide fastener. A pull-tab attachment portion is provided on a slider body portion. A pull-tab is attached on the pull-tab attachment portion. The pull-tab has a handle portion and a connection portion connected to the pull-tab attachment portion. The connection portion includes a shaft portion and a pair of rod portions made of metal and extending from both ends of the shaft portion toward the handle portion. The shaft portion has a core portion made of metal and a resin portion made of resin and covering at least a part of a circumference of the core portion. At least a part of an outer circumferential surface of the resin portion is in contact with an inner circumferential surface of the pull-tab attachment portion.

A slider for slide fasteners may include a slider body and a closure part. The closure part may include a closure portion for closing the gap between a free end portion of a pull tab attachment post and an upper blade; an upper engaging portion provided above the closure portion and engageable with the free end portion of the pull tab attachment post and a leg portion provided below the closure portion. The leg portion may include a rod portion extending from the closure portion along the coupling post and a lower engaging portion coupled to the rod portion and engageable with a lower blade.

A slider includes lower flanges placed on left and right side edges of a lower wing plate. Each of the lower flanges includes a downwardly inclined surface portion which is placed on the shoulder-opening-side tip portion on a side of its upper surface and on an outer side in a width direction of the slider, and which downwardly inclines toward a shoulder and downwardly inclines toward the outer side in the width direction of the slider. According to this, in a slide fastener having the slider, even if a sliding operation of the slider is repeated in the slide fastener, it is possible to avoid defects that the lower flange of the slider comes into sliding contact with the fastener tape and the fastener tape is broken, and it is possible to extend the life of the fastener tape.

Pull tab of a slide for slide fastener

A slide fastener slider has a body including an upper wing, a lower wing and a coupling pillar mutually coupling the respective upper and lower wings. The slide fastener slider has been cast molded to have a configuration where the post to which a pull is attached extends over the upper wing substantially in parallel with the upper wing, and then a logo or a pattern or the like has been engraved on the upper surface of the post.

Slide fastener slider

A slider for a slide fastener with an automatic stopper, includes a body forming an element guide passage into which fastener elements are insertable, a locking member swingably supported in the body by a pin and having a locking claw which is protrudable from a locking window hole formed in the body to the element guide passage and an urging member configured to urge the locking member so that the locking claw protrudes from the locking window hole to the element guide passage. A pair of lateral plate portions of the cover, which are disposed at both end portions of the pin are respectively provided with crimping protrusions which are abuttable against end faces of the pin and which are arranged at peripheral portions of a through-hole of the pair of lateral plate portions through which the pin penetrates.

Manufacturing apparatus for a slide fastener slider

There is provided an end stop for a slide fastener, in which the attachment strength can be ensured irrespective of the size of the end stop, and a core can be firmly set to a setting position with respect to the end stop. The end stop has a base and a pair of legs which extend from the base, and the end stop is formed with a receptacle which is surrounded by the base and the pair of legs. The pair of legs have a pair of opening-side ends which are provided opposite to the base, and a pair of protrusions which are provided in the receptacle adjacent to the opening-side ends, the pair of protrusions protruding inward further than opposing surfaces of the pair of opening-side ends.
