There is provided an end stop. A male member and a female member are configured to sandwich opposing side edge portions of a pair of fastener tapes from both sides thereof in an upward and downward direction. The male member includes a circular disk-shaped male base member and an inserting male portion. The female member includes a circular disk-shaped female base member and a receiving female portion. A facing surface of at least one of the male base portion and the female base portion is provided with a protrusion group. The protrusion group is configured so that a plurality of protrusions protruding to come at least in contact with each fastener tape are arranged to be spaced from each other at predetermined angles over the entire circumference of the facing surface along a circumferential direction thereof

A slide fastener chain includes a first tape and a second tape. A row of coupling elements is fixed along an inner edge of the first tape. A row of coupling elements is fixed along an inner edge of the second tape. The coupling elements of the first and second tapes being arranged such that the coupling elements of the first tape interdigitate with coupling elements of the second tape so as to secure the first and second tapes together. The chain includes a bottom stop. At least one of the tapes is provided with an extension portion which extends beyond a bottom stop portion of the tape. A width of the extension portion is less than a width of a portion of the tape which does not form part of the extension portion.

A garment or accessory includes a fabric portion including an opening and a zipper arrangement to selectively close the opening. The zipper arrangement includes a first toothed portion fixedly coupled to the fabric portion along the at least one opening, and a second toothed portion fixedly coupled to the fabric portion along the opening. The zipper arrangement also includes two sliders. Each slider is slidably received on each of the first toothed portion and the second toothed portion so as to selectively engage the first toothed portion with the second toothed portion and disengage the first toothed portion from the second toothed portion. The zipper arrangement also includes at least one stop formed by the first toothed portion and the second toothed portion such that the first toothed portion is non-releasably engaged with the second toothed portion at the at least one stop.

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.

Provided is a polyamide resin composition that is suitable as a material for slide fastener parts having good strength after being dyed. A polyamide resin composition for a slide fastener, comprising a polyamide resin and reinforcing fibers, wherein a total mass of the polyamide resin and the reinforcing fibers is 90% by mass or more of the composition; wherein a proportion of an aromatic polyamide having a melting point of from 200 to 250 C. in the polyamide resin is more than 70% by mass; and wherein a content of the reinforcing fibers in the total mass of the polyamide resin and the reinforcing fibers is from 45 to 70% by mass.

A waterproof slide fastener where first and second through-holes are drilled in a tape side edge portion of a waterproof tape at specific intervals from one another, and first and second halves of a fastener element are integrally connected to each other through first through-holes. A stopper includes a body portion and an extension portion extending from the body portion. First and second halves of the stopper straddle a pair of waterproof tapes and are integrally connected to each other through second through-holes. According to the waterproof slide fastener, a manufacturing step thereof can be simplified, and it is possible to effectively prevent water from entering the waterproof slide fastener even if it receives a lateral pulling force.

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.
