A zipper head assembly structure includes a sliding member, an elastic member and a pulling member. The sliding member has a first fixing base, a second fixing base and a through opening. The elastic member is disposed on the sliding member. The elastic member has a first fixing section mated with the first fixing base, a second fixing section mated with the second fixing base, and an inserting section movably passing through the through opening. The pulling member is mated with the elastic member. The first fixing section has a first groove structure, and the second fixing section has a second groove structure. The first fixing base is partially inserted into the first groove structure so as to fix the first fixing section in position, and the second fixing base is partially inserted into the second groove structure so as to fix the second fixing section in position.

The present invention provides a zipper head assembly structure, including a sliding element, an elastic element and a pulling element. The sliding element has a first front mating portion, a first middle mating portion and a first rear mating portion. The elastic element is disposed on the sliding element. The elastic element has a second front mating portion mated with the first front mating portion, a second middle mating portion mated with the first middle mating portion, and a second rear mating portion mated with the first rear mating portion. The pulling element has a pivotal portion pivotally disposed between the sliding element and the elastic element. The second middle mating portion extends inwardly from a middle body of the elastic element, and the width W1 of the middle body and the width W2 of the second middle mating portion conform to the equation: (W1W2)/2W2.

A slide fastener of the present invention includes: a first fastener stringer; a second fastener stringer; and a slider which couples or separates the first and second fastener stringers, in which the second fastener stringer separated from the slider is inserted into the slider wherein the first fastener stringer and the second fastener stringer are coupled in a vertical direction. Accordingly, a row of fastener elements of the second fastener stringer separated from the slider is inserted into the slider by first and second fastening members when a fixing pin and an insertion pin are coupled in a vertical direction, and as a result, the coupling operation is convenient.

A sliding member is provided, the sliding member includes a first sliding body, a second sliding body opposite to the first sliding body, a connection body connected between the first sliding body and the second sliding body, a first convex body disposed on the first sliding body, and a second convex body disposed on the first sliding body. The first convex body has two convex ribs and two convex portions disposed on a top side of the first sliding body to respectively adjacent to the two convex ribs. A movable cover body has two sliding portions respectively movably contacting the two convex ribs and respectively separately contacting the two convex portions. A zipper head assembly structure using the sliding member is further provided.

A 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.

There is provided a slider assembly for a slide fastener, including: a slider body; a pull-tab; and a resilient locking member. The pull-tab is provided with a window aligned with an aperture in an upper wing of the slider body when the pull-tab is in a first angular end position. A distal end of the locking member extends towards a guide channel through the window and the aperture. The locking member is configured to be resiliently biased towards a locking position where a distal end thereof protrudes in the guide channel. A proximal end of the pull-tab has a cam cooperating with the locking member such that the locking member takes the locking position when the pull-tab is in the first angular end position, and the locking member is moved towards an unlocking position when the pull-tab is pivoted away from the first angular end position.

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.
