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 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.

The prevent 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 elastic member has a first fixing portion fixed on the seat portion, a second fixing portion fixed on the seat portion, an exposed portion connected between the first fixing portion and the second fixing portion and exposed out of the seat portion, an elastic portion extended from the first 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. The pulling member is movably mated with the retaining member.

The device provides a locking slide assembly for a zipper, and a method for manufacturing a locking zipper slide assembly. The locking slider assembly is formed in a single die cast operation to include the locking slider and the pull member being formed simultaneously. Whereby the bridge and pull loop are formed with their full geometric shape and without converging flat surfaces caused by tooling limitations found in the prior art.

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.

A slider, includes a slider base, a pull-tab, a connecting shaft and a spring; the slider base includes an upper blade, a lower blade, and a connecting pin connecting the upper blade and the lower blade; said pull-tab is integrated with the connecting shaft; the pull-tab includes a pull-tab body, with a spring mounting part and a locking part set at the anterior-end-face of the pull-tab body; the anterior-end-face of the pull-tab body is set as a locking vertical plane and the bottom of the pull-tab body is set as cambered surface; the connecting shaft is fixed to the anterior-end of the pull-tab body and the length of the connecting shaft is larger than the width of the anterior-end-face of the pull-tab body; the connecting shaft runs through the spring mounting part and the locking part and extends to both sides of the anterior-end of the pull-tab body.

A separable bottom end stop for a reverse opening-type slide fastener, in which left and right element rows of left and right fastener stringers can be opened from an upper end and a lower end, the slide fastener includes a lower slider for opening the left and right element rows from the lower end, the lower slider includes a locking claw, which is elastically biased to a protruded position protruding into an element guide path of the lower slider, an insert pin connected to the lower end of one of the left and right element rows, and a box pin connected to the lower end of the other of the left and right element rows. At least one of the box pin and the insert pin includes a release groove capable of receiving the locking claw on a side surface opposing to the other side surface.

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 slider operable in a simple operation manner and capable of reducing an overall volume is provided. The slider includes: a slider body; a claw member positioned on the slider body and having a lock pin portion extending to an interior of the slider body to establish a locked state; an operation piece positioned on the slider body and connected to the claw member. The operation piece has first and second shaft portions that are separately positioned. The operation piece is rotatably positioned on the slider through the first shaft portion and connected to the claw member through the second shaft portion. Upon pressing the operation piece and enabling one side of the operation piece to rotate toward the slider with the first shaft portion as an axis center, the second shaft portion lifts the claw member to release the locked state in the interior of the slider body.
