There is provided an opener of a slide fastener. A separable pin accommodation part of a retainer has upper and lower walls facing each other, a pair of wall parts protruding from the upper and lower walls in a direction of narrowing an interval therebetween, and a bottom wall configured to join the upper and lower walls at the rear of the pair of wall parts. The pair of wall parts extend toward the bottom wall from a rear side relative to front ends of the upper and lower walls. A pair of restriction parts are configured to collide with each other so as to restrict a position of a rearmost end of a separable pin to be inserted into a separable pin hole to a position between the bottom wall and front ends of the pair of wall parts are separately provided for the retainer and the separable pin.

A zipper fastener system is provided for removably connecting separate structures. More particularly, a zipper fastener system is provided having connection sections attached to independent pieces that may be secured to and removed from each other utilizing two sliders, such that, when the connection sections are secured to each other, the two sliders permit an access opening of variable length and location along the connection sections and permit adjustments from either side of the zipper fastener system.

Example embodiments of the present invention relate to a system comprising a zip-locker and a zip-locker receiver. The zip-locker comprises a first portion and a second portion configured to fasten to an interconnect, at least one of the first portion and the second portion having ratchet teeth formed and extending longitudinally on an outer surface thereof. The zip-locker receiver is configured to ratchetably receive the zip-locker and comprises an aperture and a pawl disposed within the aperture configured to complement and cooperate with the ratchet teeth of the zip-locker to prevent removal of the zip-locker from the aperture of the zip-locker receiver at times the pawl of the zip-locker receiver is engaged with the ratchet teeth of the zip-locker.

Zipper is disclosed that allows one handed operation. Zipper has a split slider and a zipper closure. The split slider has a first slider member releasably coupleable to a second slider member. The first slider member engages a first plurality of zipper elements attached to a first fabric portion, and the second slider member engages a second plurality of zipper elements attached to a second fabric portion. The zipper closure comprises a first closure member releasably coupleable to a second closure member. The first closure member and the second closure member are positioned on the first fabric portion and the second fabric portion, respectively, such that the two closure members may be coupled by applying a force perpendicular to the surface of the fabric portions. In one embodiment, the first and second closure members are configured to couple simultaneously with the coupling of the first and second slider members.

A lower stop assembly for slide fasteners comprises a left stop member and a right stop member. The inside of the right stop member is provided with a right slot and an annular orifice both extending in the direction of the inside, the annular orifice being located at the front end of the right slot and in direct communication with an opening of the right slot. The left stop member can be movably inserted into the opening of the right slot and then released from lateral notches of the right slot. As the left stop member can be released from the lateral notches of the right slot, when the left stop member needs to retreat from the right slot, the left stop member may rotate around the outer lateral wall of the annular orifice under the drive of the left slide fastener belt to come out from the right slot.

The slide fastener has a separable bottom end stop, and the separable bottom end stop has at least an insert pin and a box pin. The insert pin has an escape portion provided with an inclined surface or a curved surface along which the thickness dimension of the insert pin decreases in the direction of the tape width toward the side edge that faces the box pin, the escape portion being positioned in the front-end corner portion of a first-surface of the insert pin, the corner portion being positioned along the edge that faces the box pin. This allows the escape portion of the insert pin to function as an interference prevention means, efficiently prevent chain failure in an element row when the slide fastener is bent into a U-shape, and maintain stable engaging.

A two-way insertion assembly includes an insertion rod and an insertion pin for mounting two-way sliders, an insertion pin side wing base is provided on a cloth tape of the insertion pin; and an insertion pin side wing channel for the two-way sliders to enter is formed between the insertion pin and the insertion pin side wing base, and the insertion pin side wing channel is provided with a limiting portion capable of transversely limiting the sliders moving in place. The problem of the cloth tape coming into an inner cavity of a slider due to a transverse shake of the slider can be solved, and rapid and precise alignment of inner cavities of the two-way sliders can be easily achieved, thereby facilitating quick and accurate insertion and pull-out of the insertion rod.

A slide fastener includes: a pair of stringers; and a slider. The pair of stringers include: a pair of tapes, a pair of element rows each including a plurality of elements, and an opener. At least one element row includes the elements of a plurality of types, and is classified into a neighboring class, and a remote class. Regarding an impact to be applied to the elements and the stop claw which collide inside the slider when a force for pulling out one of the element rows from the slider is applied to the one element row, the elements forming the remote class include strong elements of a type configured to strengthen the impact more than the elements forming the neighboring class. All of the elements forming the neighboring class are weak elements of a type configured to weaken the impact more than the strong elements.
