Problems solved by technology

[0006] Although the slider shown in FIG. 15 has a smooth surface that is not afraid of injuring the user, no pull tab is installed on the slider body 1', so it is inconvenient for the sliding operation of the slider.
In addition, since the decorative surface 38' coated on the surface of the slider body 1' has no fixed means, it may be detached from the slider body 1'.
Therefore, there is a problem that this slider cannot be used stably for a long time

Embodiment Construction

[0041] Preferred embodiments of the zipper slider will be described in detail below with reference to the accompanying drawings.

[0042] In the zipper slider of the present invention, the main slider body 1 is made of double-cast zinc alloy or aluminum alloy, and the linear body 30 is made of knitted or braided synthetic resin yarn, and the linear body is mounted on the top of the body 1. On the surface, as a pull pan. To mount the linear body 30 on the main body 1, a molded resin body 25 is formed on the main body 1 by insert molding such as polyurethane and polyester, thereby fixing the linear body 30 to the main body 1, thereby making a slider without any protrusions on the surface of the body 1. The body 1 of the slider can be made of polyamide, polyester and polypropylene as well as metal. In addition, the molded resin body 25 on the body 1 can be made of synthetic resin or rubber such as vinyl chloride, polyethylene, polyamide, polypropylene.

Abstract

This invention provides a slider for use in sport goods, and its surface is smooth without any protrusion thereby providing no danger to a user. On a top surface of an upper wing (2) of a slider body (1) for slide fastener, a thread attachment portion (10) for attaching a thread body (30) as a pull and a fixing portion (20) for fixing molded resin body (25) formed by insert-molding synthetic resin on the upper wing (2) are formed integrally with the slider body (1). Then, synthetic resin is insert-molded to bury and cover the thread attachment portion (10) to which the thread body (30) is already attached and the fixing portion (20) so that a molded resin body (25) is formed on the upper wing (2) and fixed thereon. As a result, there is provided a slider whose body (1) has a smooth surface and only contains a flexible thread body (30).

Description

technical field [0001] The present invention relates to sliders for zippers mainly used on sportswear, and in particular to a slider with a safe smooth surface that does not injure the user, for example on the surface of the pull-tab installation part There are no protrusions and no hard pull tabs are installed on the surface. Background technique [0002] In the slider of a zipper disclosed in U.S. Patent No. 2253494, a through hole 34' vertically passes through the guide post 4' of the body 1' of the zipper slider, and a round linear body 32' passes through the through hole 34'. The holes 34' are shown in FIG. 14 . Stop metal pieces 35' are then attached to both ends of the round linear body 32' to prevent it from slipping out of the through hole 34'. As far as this type of zipper slider is concerned, various sliders are known. [0003] In addition, according to the slider of the slide fastener disclosed in Japanese Utility Model Publication No. 61-204506, as shown in F...
