A fastener pull assist apparatus arranged within a housing that is configured to assist in sealing a zipper at the back of a garment, such as a dress.

The invention relates to a zipper with automatic coupling, which comprises a part fixed to the clothing (1, 1, 4) and an exchangeable part (2, 2, 3), the fixed part comprising first joining elements (1, 1) solidly joined to a garment (4) by one of the sides thereof and which can be joined on the opposite side to the exchangeable part. According to the invention, the exchangeable part comprises second joining elements (2, 2) disposed longitudinally, in parallel with respect to a zipper closure (3) and fixed to said zipper closure (3), the first joining elements (1, 1) and the second joining elements (2, 2) together forming a male-female joint or clip joint.

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.

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.

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 robotic zipper system for joining and separating zipper halves of a zipper tape. A chassis retains an actuator that drives a zipper slide geometry along the zipper tape to join or separate the zipper tape. A sensor can determine zipper slide position, and a control module can provide an electrical signal to the motor to move in forward or reverse. The actuator can have a motor that drives a gear system that mechanically engages zipper teeth. Teeth of the gear system can be out of phase to mesh with alternating gaps between the zipper teeth. The actuator can be removable relative to a zipper slide. Zipper slide geometry could be integrated into the chassis, such as in the form of a channel, potentially with a central post. A sensor could be positioned to detect the presence or absence of zipper teeth through an opening in a base plate.
