Automatic lock slider for concealed slide fastener

摘要

In an automatic lock slider for a concealed slide fastener, a fastener-element guide post (7) of a slider body (1) has an upper groove (9) receiving a locking lever (2) and a lower groove slidably receiving a sliding end (25) of a pivoting release member (3). A spring (13) mounted in the guide post (7) acts on an actuating arm (17) of the locking lever (2) to urge a locking pawl (16) of the locking lever (2) to normally project into a fastener-element guide channel (8) of the slider body (1). An ornamental knob (4) attached to the pivoting release member (3) covers exposed part of the slider body (1). As the knob (4) is pulled to pivotally move the release member (3), the locking pawl (16) is retracted from the guide channel (8).
