String fastener

Abstract

Provided is a string fastening tool comprising sliders having string passing holes, and a case arranging the sliders to slide from the openings on the end-face sides to the inside space and having windows formed in two opposed faces and enabled to communicate with the passing holes, so that the strings can be retained and prevented from coming out by moving the positions of the through holes relative to the windows through the slides of the sliders from the state, in which the pull-side end portions are threaded into the windows and the passing holes. The string fastening tool is constituted of three members of the case and the paired sliders. The case has the inside space and the windows on the two sides. The sliders are independently arranged in the spaces on the two sides, and each slider has two through holes at two portions. The end portions of the strings are led in different directions and threaded through the windows of the corresponding sides and the individual through holes,and are pulled in the different directions so that the individual sliders can be slid to retain the end portions of the strings.

Description

technical field [0001] The present invention relates to a belt clip that is used to lock both ends or one end of a belt arranged on the front side of a shoe or around the opening of a bag to any length or to adjust the tightening degree of the belt. Background technique [0002] As exemplified in Patent Documents 1 to 3, this belt clip includes: a slider (also referred to as an insert, a slider, etc.) forming a through hole for the belt; the slider is slidably arranged from the opening on the end face side to the inner space. , and form the housing (also referred to as the main body, the outer housing, the outer body, etc.) on the opposite upper and lower surfaces of the window part that can communicate with the above-mentioned through hole; Force mechanism (composed of coil springs or elastic sheets of resin). Moreover, when in use, the sliding block slides from the casing to the protruding direction by the force of the force-applying mechanism, and the position of the thr...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned existing belt clip is simple and easy to use due to the ability to easily adjust the amount of pull-out of the belt, etc., but it is necessary to apply an urging mechanism to the slider, so it is difficult to achieve further miniaturization. Lightweight and cost reduction

That is, in the urging mechanism, if a coil spring is used as in Patent Documents 1 and 3, the number of parts will increase, and a space for arrangement will be required, and if the elastic piece and the slider are integrally formed as in Patent Document 2, the molding die will be changed. In addition, if the elastic piece is short, it is difficult to provide good elastic properties, and if it is long, it requires a large configuration space
