There is provided a slide fastener slider. A pull tab has a rotatable region including laid-down positions and a stood-up position. Within the rotatable region of the pull tab, a locking pawl is elastically deformed to move a cover portion, and a pawl portion is arranged to be inserted into and removed from an element guide passage in accordance with movement of the cover portion. When the pull tab is completely laid down toward the shoulder mouths and rear mouth relative to the slider body, the pull tab has respective regions in which the pull tab is rotatable over a predetermined angle without exerting any load on the locking pawl.

The present disclosure provides a zipper head assembly structure and an elastic member thereof. The zipper head assembly structure includes a sliding assembly and a pulling member. The sliding assembly has a base portion, a seat portion, an elastic member and a retaining member. The seat portion has a positioning through hole. The elastic member is disposed on the seat portion to elastically abut against the retaining member. The elastic member has a fixing portion fixed on the seat portion, an elastic portion extended from the fixing portion, and an abutting portion extended from the elastic portion for abutting against the retaining member. The retaining member is movably disposed on the seat portion for movably contacting the elastic member, and the retaining member has a retaining portion for passing through the positioning through hole. The pulling member is movably mated with the retaining member.

The instant disclosure provides a zip slider structure including a slider body, a tab-holder and a pull-tab arranged between the tab-holder and the slider body. The slider body includes a first slide portion, a second slide portion and a connecting portion including a joint recess. The first slide portion includes a first slide surface, an arranging surface, a first recess, a second recess and a first extension end. The tab-holder includes a body portion, a first bending portion extending from one end of the body portion and passing the first recess, and a second bending portion extending from the other end of the body portion. The first bending portion includes a slot joining with the first extension end, the second bending portion includes a holding end joining with the joining recess, the body portion includes an attaching member extending from the body portion and joining with the second recess.

A zipper includes a slider head including a base; two side walls; two roofs each inwardly extending from a top of the side wall; a division wall on a longitudinal central line of the base; two grooves each defined among and by the roof, the side wall, and the base at the same side; a spring biased front mounting block on a top of the division wall and having a longitudinal central trough; a rear mounting member having a through hole; and a well between the front mounting block and the rear mounting member; a coupling including a hook at a rear end, and an intermediate recess, the coupling pivotably secured to the front mounting block; and a zipper pull releasably secured to the hook. The hook is disposed in the through hole to hold the zipper pull and the slide head in position.

Slider includes a slider body with an insertion hole extending toward a lower wing from an insertion entrance on a side of an upper wing so as to form a hollow in the interconnection pillar; a pull tab mounted onto the slider body so as to be pivotable over the upper wing between a collapsed posture and an upright posture; a spring member mounted onto the slider body so as to sandwich a portion of the pull tab; and a cover attached to the slider body so as to cover at least the spring member. The spring member includes a front leg inserted into the insertion hole via the insertion entrance. The cover is configured to include a limiting portion that limits, at a position over the insertion hole, upward displacement of the front leg of the spring member.

There is provided a slide fastener slider. A front mounting portion and a rear mounting portion are respectively provided with receiving grooves for receiving a lock member. The receiving grooves have right and left side walls. Protrusions are respectively provided on upper end edges of the side walls of the front mounting portion. When the upper end portions of the side walls of the front mounting portion are inclined in a direction of approaching each other, the protrusions approach each other, and the protrusions cover the lock member more largely relative to portions of the side walls other than the protrusions.

An invisible zipper head assembly structure includes a sliding member and a pulling member. The sliding member has a base portion, a first lateral wall portion, a second lateral wall portion, a seat portion, an elastic component, and a retaining body. The retaining body has a positioning portion passing through a positioning through hole of the seat portion. The pulling member is movably mated with the retaining body. The thickness of the first lateral wall portion is smaller than the thickness of the second lateral wall portion. The first symmetric center line of the base portion passes through a geometric center point of the positioning through hole, and the second symmetric center line of the seat portion is horizontally moved relative to the first symmetric center line by horizontal offset and along a horizontal direction from the second lateral wall portion to the first lateral wall portion.

A garment has: a pair of fabric panels each connected to a zip tape; the zip tape including a pair of rows of zip teeth; a zip slider, having a bridge extending upwardly and a pull tab connected to the bridge via an intermediate link; the zip slider being movable along the zip tape to interdigitate the rows of zip teeth by pulling of the pull tab; the panels provide a pair of lips extending over the zip teeth thereby to cover the slider; the intermediate link, pull tab and bridge are constructed so that rotation of the pull tab causes the intermediate link to bear against outer surfaces of the bridge.

A zip slider has: a slider body having upper and lower elements providing two entry channels through which zip teeth pass and slider un/mating; a pull tab having a cam; a biasing spring having a locking prong and a follower surface bearing against the cam. The cam on the follower surface biases the tab into a closed position in which it lies against the upper element. When the tab is in a lifted position, the cam action on the follower surface raises the prong above the mated teeth, enabling relative motion of the teeth and body; when the tab is in the closed position, the prong bears against the teeth to prevent unwanted relative slider and teeth motion. The slider has a counter bias, acting between the upper element and the tab to apply a biasing force on the tab acting against the action of the cam and follower surface.
