Problems solved by technology

However, in the case of die-casting the upper and lower engaging sliders, there are many problems in industrial production. For example, due to the complex shape of the mold, sliding cores in more than three directions are required, and due to the presence of sliding cores that advance obliquely, there are many problems in industrial production. However, it is impossible to increase the number of cavities of the mold, and it is difficult to remove the burrs during forming on the parting line, etc.

Embodiment Construction

[0048] In this specification, when constructing a slide fastener, the sliding direction of the slider is referred to as the front-rear direction, the direction in which the slider slides to engage the element rows is referred to as the front, and the direction in which the slider slides to separate the element rows is referred to as rear. Moreover, let the direction perpendicular|vertical to the surface of a fastener tape be an up-down direction, let the direction which goes toward an upper blade from a lower blade be upper, and let the direction which goes toward a lower blade from an upper blade be downward. In addition, the direction parallel to the surface of the fastener tape and perpendicular to the sliding direction of the slider is defined as the left-right direction, and when the slider is slid forward, the right side of the advancing direction of the slider viewed from above is defined as the right direction. , defining the left side of the forward direction as the l...

Abstract

According to the present invention, there is provided a vertically engaging slider made of metal, which is suitable for the industrial production. The front end wall (109) of the slider according to the present invention has a plastically deformed portion (111) caused by plastic working in which with the front end wall (109) itself as a fulcrum, the back opening (110) is deformed from an open state to a closed state in the upper-lower direction.

Description

technical field [0001] The present invention relates to an upper and lower engaging slider for slide fasteners. In addition, the present invention also relates to a slide fastener having the slider. Background technique [0002] Zippers are used as opening and closing parts for articles, not only for daily necessities such as clothing, bags, shoes, and miscellaneous goods, but also for industrial products such as water tanks, fishing nets, and space suits. [0003] Normally, a zipper is mainly composed of a pair of long zipper tapes, a chain element row installed along one side edge of each zipper tape as an engaging part of the zipper, and a pair of chain element rows are engaged and separated to control the opening and closing of the zipper. These three parts constitute a closed slider. The slider has a function of engaging or separating the element rows by sliding while inserting the element rows inside. A common slider is a left and right engaging type, which has a ro...
