Abstract

The present invention provides a slider for a concealed type slide fastener with a separable bottom end stop, capable of, when an insert pin is inserted with an abnormal status, restoring the status to a normal one. In the slider for a concealed type slide fastener with a separable bottom end stop, a recess (20) is provided in a shoulder mouth (15) of a lower blade (5) sideways of a diamond (6) erected from a body (2) of the slider (1) and a slope is formed on a side wall (21) sideways of the diamond (6) and a rear mouth (16) side of the recess (20). Consequently, even if the insert pin (28) is inserted with an abnormal condition, for example, such that the insert pin (28) is drooped in a vertical direction with respect to a fastener tape (22), the slope of the side wall (21) restores thefastener tape (22) into a parallel condition quickly and after that, the insert pin (28) can be inserted into a box (26), thereby attaching the bottom end stop smoothly and easily.

Description

technical field [0001] The present invention relates to a slider for a concealed zipper, which is used in a detachable bottom end stop composed of a socket, a seat bar and a plunger, the detachable bottom end stop being fitted to the teeth of the concealed zipper On the end of the chain, when the slider is operated in the front and rear direction, the detachable bottom stop will separate the tooth chain in the closed state into left and right tooth chains and close the tooth chain in the open state. Slider for concealed zippers with detachable bottom stop for the insertion capability of the rod into the slider. Background technique [0002] In conventionally known sliders for concealed zippers with detachable bottom stops, as shown in FIGS. , and a pull tab mounting portion 107 with a locking mechanism is provided on the top of the wedge portion 106, although the locking mechanism is not shown in the figure. The pull tab mounting portion 107 extends laterally on the wedge ...
