Slider for slide fastener with automatic stop means

摘要

A slider with automatic stop function for a linear slide fastener in which leg portions of fastener elements are covered with blades and the like. A slider body (1) comprises a pair of wings, namely an upper wing (2) and a lower wing ( 3 ) which are interconnected by a guide post or spacer ( 4 ). A narrow linear rib ( 6 ) is provided on the inner face of the upper wing ( 2 ) to guide edges of blades for covering leg portions of fastener elements and to slide on the upper faces of the coupling head portions of the fastener elements. Pressure lands ( 7 ) are provided at a lower height than the rib on the both sides of the rib ( 6 ) in the neighbourhood of the guide post and slide along the blades being pressed against the fastener elements. A leaf spring ( 8 ) with automatic stopping function is disposed on the surface of the upper wing ( 2 ) so that the tip end thereof serves as a stop claw ( 9 ). The stop claw ( 9 ) is inserted into the middle portion of the linear rib ( 6 ) and the pressure lands ( 7 ) to stop the sliding of the slider automatically.
