Abstract
A pull tab releasable slider lock mechanism includes a leaf spring supported within a cover, which is fixedly mounted on the slider body, by having its opposite ends engaged in recesses formed in the opposed inside surfaces of the cover. A part of this leaf spring is formed into a resilient tongue which is engaged with a locking member to normally bias its terminal pawl into the guide channel in the slider body. In another embodiment, the resilient tongue of the leaf spring is integrated with the locking pawl, thereby dispensing with the separate locking member.
Claims5
An automatically locking slider for slide fasteners comprising, in combination, a body defining a guide channel therein, a cover fixedly mounted on the slider body, a leaf spring supported within the cover by having its opposite ends urged against the opposed inside surfaces of the cover under its own resiliency, the leaf spring having a part thereof formed into a resilient tongue, a locking pawl normally biased by the resilient tongue of the leaf spring into the guide channel in the slider body, and a pull tab pivotally mounted on the slider body and adapted to move the locking pawl away from the guide channel in the slider body against the bias of the resilient tongue of the leaf spring upon exertion of a pull on the pull tab.
