ZIP SLIDER

摘要

A zip slider has: a slider body having upper and lower elements providing two entry channels through which zip teeth pass and slider un/mating; a pull tab having a cam; a biasing spring having a locking prong and a follower surface bearing against the cam. The cam on the follower surface biases the tab into a closed position in which it lies against the upper element. When the tab is in a lifted position, the cam action on the follower surface raises the prong above the mated teeth, enabling relative motion of the teeth and body; when the tab is in the closed position, the prong bears against the teeth to prevent unwanted relative slider and teeth motion. The slider has a counter bias, acting between the upper element and the tab to apply a biasing force on the tab acting against the action of the cam and follower surface.

主权项

1. A zip slider comprising a body movable along opposing pairs of zip teeth to cause inter and extradigitation of the zip teeth;
a pull tab pivotally mounted to the body and having a resting position in which it lies against the body and a pulling position in which it is pivoted from the resting position; a locking prong which is engaged with interdigitated teeth to prevent relative motion of the slider and teeth when the pull tab is in the resting position, and disengaged to permit the relative motion when in the pulling position; a damping bias acting to apply a damping bias to the pull tab relative to the body when in the resting position.
