Slide fastener slider

Abstract

Provided is a slide fastener slider that improves workability when attaching a handle holder to a slider body, has strong attachment strength, and a good appearance. The handle holder (40) has: flanges (41) that extend in the length direction, and extend in the width direction from the left and right sides of a fixed-side base end (43); and a protruding part (42) that protrudes toward the slider body (20). The slider body (20) has: sliding grooves (29) that are formed on the front end of an upper winged plate (21), and accommodate the flanges (41); and a recess (30) that engages with the protruding part (42). By inserting the flanges (41) into the sliding grooves (29), and crimping the upper surface (21b) of the upper winged plate (21), which is positioned above the sliding grooves (29), toward the flanges (41), the protruding part (42) is forced to engage with the recess (30), and the handle holder (40) is fixed to the slider body (20).

Description

technical field [0001] The present invention relates to a slider for a zipper, in particular to a slider for a zipper which greatly improves the assembly property between a slider holder and a slider main body and has high production efficiency. Background technique [0002] Conventionally, as a structure for attaching the handle holder to the slider main body, a method of caulking using a cylindrical pin is currently used, but this requires providing a shaft hole in the handle holder and the slider main body. Then, the slider for slide fasteners which improved productivity without using a cylindrical pin when attaching a handle holder to a slider main body was invented. [0003] For example, in the slide fastener slider described in Patent Document 1, after fitting the flange provided on the handle holder into the slide groove of the slider main body, the flange provided on the slider is fixed by using a punch or the like from the upper surface side. The thickened part for...

Problems solved by technology

[0009] However, in the slide fastener slider described in Patent Document 1, it is necessary to provide a thickened portion for caulking on the slider main body, and there is a need to further increase the attachment strength between the handle holder and the slider main body.

In addition, in the slide fastener slider described in Patent Document 2, there is a problem that since the handle holder and the slider main body are caulked from two places, although the mounting strength is improved, the handle may be damaged. There are traces of riveting on the side of the retainer, and since the flange is formed with a thin-walled fixing recess, the processing is complicated
