Abstract

A fastener wherein right and left side edge portions can be engaged using a magnetic force, and which can be applied preferably for plastic article such as clothes and further prevented from being opened carelessly even if a lateral pulling force is applied when right and left elements are engaged. In the fastener, a plurality of first and second magnetic elements(3A,3B) having magnetism are provided in lines on a pair of first and second fastener tapes(3A,3B), the first and second magnetic elements(3A,3B) are adsorbed to each other using a magnetic force, characterized in that the first and second magnetic elements have head portions(7), a leg portion(8), and engagement / disengagement portions(9,10) formed at the head portions and mechanically engaged with or disengaged from each other between the first and second magnetic elements(3A,3B), the first and second magnetic elements are respectively disposed at predetermined intervals, the magnetic elements(3A) of one fastener tape(2A)(3B) are adsorbed to spaces between the adjacent magnetic elements of the other fastener tape(2B), and the first and second magnetic elements(3A,3B) are engaged with each other alternately.

Description

technical field [0001] The present invention relates to a slide fastener for opening or closing a fly of clothes, and more particularly, to a slide fastener for attaching a magnetic element provided with magnetism by a magnet or the like to opposing element attachment edge portions of a pair of slide fastener tapes to engage the opposite right and left magnetic elements using the magnetic force of the magnetic elements. Background technique [0002] USP No. 4,399,595 discloses a zipper that utilizes the magnetic force of a magnet to open or close the front of a garment. In the slide fastener disclosed in USP No. 4,399,595, magnets are arranged at predetermined intervals on opposite side edge portions of a fly portion of clothing so that N poles and S poles alternately appear. By overlapping the front side of one side edge part with the back side of the other side edge part, the N pole and S pole of the magnet provided on the side edge part are magnetically attracted to each...
