Abstract

Automatic block cursor, for a slide fastener, characterized in that it comprises: (a) a cursor body having a pair of parallel and spaced upper and lower fins joined by a neck located in the center of its front end to define a channel of substantially Y-shaped guide through said cursor body, said upper fin having a longitudinally extending slot practiced on its outer surface, said slot terminating in a slit extending transversely at its end remote from the front end of said cursor body, and said slit extending through said upper fin; (b) a pull tab having a tail at a first end and which is mounted on said top tab for pivotal movement between its flat and raised positions; and (c) elastic locking means mounted longitudinally on said upper flap and having an end anchored to the forward end to said cursor body, said resilient locking means having a locking tooth housed in said transverse groove and elastically cooperating in said means locking elastics with said pull tab so that when said pull tab is actuated to its raised position, said tail causes said locking tooth to rotate about an axis parallel to the longitudinal axis of said slider body outside of said guide channel by a curved path oriented transversely with respect to said longitudinal axis.
