Embodiment Construction

[0054] The invention will now be further explained by means of embodiments with reference to the accompanying drawings.

[0055] refer to figure 1 , figure 1 A slide fastener according to a first embodiment of the present invention is shown. exist figure 1 (the slider of the zipper is omitted for clarity) shows the zipper in a generally closed position.

[0056] figure 1 The zipper 10 includes a first stringer 2 and a second stringer 3 . The tooth chain belts 2, 3 are respectively composed of cloth tapes 5a, 5b and each has a cord (not shown) protruding from the upper and lower surfaces of the cloth tapes along the opposite longitudinal edge portions of the cloth tapes 5a, 5b and chained together. Teeth 7 are mounted on the rope. Preferably, the slider (not shown) includes a pull tab to allow the user to move the slider along the elements 7 of the zipper 10 .

[0057] According to the invention, the cloth tapes 5a, 5b also comprise a fabric layer coated or laminated wit...

Abstract

A slide fastener is provided. Each of a pair of first (2) and second (3) stringers includes a tape (5a, 5b) and a row of coupling elements mounted on a longitudinal edge of the tape. Each of the coupling elements comprises a first non- connecting portion (8) at an upper side of the tape and a second connecting portion at a lower side of the tape. The second connecting portion comprises a head portion and a body portion. The head portion is engageable with a head portion of opposing coupling element. The body portion is fixed to the tape.

Description

technical field [0001] The present invention relates to a slide fastener. More particularly, it relates to a zipper having a simplified connection mechanism whereby the elements do not appear to engage the front surface of the zipper in the closed position allowing good abutment of opposing elements while still providing improved zipper flexibility. Background technique [0002] Where it is always desired to generate new designs for the fashion industry and the furniture industry, the characteristics of a zipper or zipper on a particular garment or item can have a significant impact on the overall image of the finished product. [0003] In addition, however, while having an attractive appearance, zippers have a functional role and are often the key to clothing or furniture. [0004] A problem associated with zippers is the inherent property of the elements or teeth forming the closure mechanism for the zipper to receive foreign objects. If left unchecked, the presence of f...
