Embodiment Construction
[0037] The core of the present invention is to provide a two-way opening and closing zipper, which can be opened or closed from the middle to both ends, without the need for two sliders to be pulled to the same end at the same time, so that the pulling and closing operation is more convenient.
[0038] In order to make those skilled in the art better understand the technical solution of the present invention, the two-way opening and closing slide fastener of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0039] The two-way opening and closing zipper of the present invention comprises the first fastener element 1 and the second fastener element 2 respectively fixed on two fabric belts, and the first fastener element 1 and the second fastener element 2 refer to the fastener elements arranged on different fabric belts constitute a whole; Figure 1A and Figure 1B Shown, are respectively ...

The invention discloses a two-way opening and closing zipper. Positioning square blocks and positioning teeth are located on two fabric belts and located on the positions corresponding to the middles of first chain teeth and second chain teeth; the positioning square blocks and the positioning teeth in the same set are mutually matched to achieve two-dimensional positioning, and the starting positions of the chain teeth are determined in the length direction of the chain teeth and the direction parallel to the fabric belts and perpendicular to the chain teeth; and each positioning square block is correspondingly provided with a pull head, avoidance notches are formed in upper bottom plates or lower bottom plates of the pull heads and used for avoiding the positioning teeth, and thus the positioning square blocks and the positioning teeth are in mutual positioning fit. During using, the middles of the first chain teeth and the second chain teeth make contact, the positioning square blocks and the positioning teeth conduct two-dimensional positioning, the two pull heads are pulled towards the two ends, thus the first chain teeth and the second chain teeth are engaged in a staggered mode, the zipper is pulled from the middle to the two ends and separated from the two ends to the middle, the two-side parts of the zipper are relatively independently controlled, the two pull heads do not need to be simultaneously pulled to the tail end each time, so that pulling operation is more convenient.
Description
technical field [0001] The present invention relates to the technical field of zippers, more specifically, to a two-way opening and closing zipper. Background technique [0002] A zipper is a product used on clothing, bags or other items to secure two pieces of cloth tape or other flexible material. The zipper is composed of chain teeth, sliders, top stop (front code), bottom stop (rear code), locking parts and other components. Generally, a zipper has two chain belts, and each chain belt is equipped with a row of chain teeth and two rows. The chain teeth are arranged in a staggered manner. [0003] The slider clamps the chain elements on both sides, and the slider slides along the chain elements with the help of the pull tabs set on it, so that the chain elements on both sides engage or disengage each other; when the slider makes the chain elements on both sides approach each other, mutual Engaging to close the zipper, the zipper disengages when the pull pulls the side el...
