Slide fastener slider for easy mounting of a pull tab

Abstract

A joiner and a slide fastener slider incorporated with the joiner includes a slider body having an upper wing and a lower wing connected by a neck to define a channel for insertion of a slide fastener. A lug is integrally formed on the upper wing with a gap between the lug and the upper wing for the insertion of a pull tab. A joiner has a locking arm inserted into a bore of the upper wing. A spring piece and a pair of positioning legs are formed at one end of the joiner, and a pair of position-defining arms is formed at an opposite end of the joiner. A pair of inverse hooks is formed on the pair of position-defining arms. The lug includes a recess for receiving the spring piece, and a pair of recesses for receiving the pair of positioning legs. A position-defining element provided on the lug for limiting the displacement of the pair of position-defining arms.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from Hong Kong Short Term Patent Application No. 09100802.9, filed on Jan. 23, 2009, the content of which is hereby incorporated in its entirety by reference.FIELD OF THE INVENTION[0002]The present application relates to a joiner and a slide fastener slider incorporated with the joiner for easy mounting of a pull tab.BACKGROUND OF THE INVENTION[0003]The existing slide fastener sliders include two parts, namely, a pull tab and a slider body, wherein the pull tab is always fixedly mounted to the slider and thus cannot be mounted at will according to users' demand. However, with human's endless pursuit for an easy life and for various other reasons, there has been a need to mount the pull tab to the slider by the users themselves, that is, after-manufacture and / or after-market installation of the pull tab. To this end, different types of sliders have been designed to meet this need, such as the slide fastener ...

AI Technical Summary

Benefits of technology

[0004]The object of the present application is to provide a slide fastener slider having a simple structure which can be easily manufactured with low cost and which enables a user to easily mount the pull tab on the slider.

[0005]According to one aspect of the invention, there is provided a simple joiner for coupling to a lug on the slider of a slide fastener for easy after-manufacture and after-market installation of the pull tab to the slider. The jointer having a proximal end and distal end is a single piece (preferably made of a single piece of metal sheet), easily manufactured with lost production costs, which comprises

Problems solved by technology

However, these designs have issues with complicated structures, low production efficiency and high manufacturing costs.

As a result, these slide fastener sliders have not been commonly acceptable in the field.
