Abstract
A slide bolt unit is provided for releasibly locking a door or window or the like, such as a semi-active door in a double door entry set. The slide bolt unit includes an elongated slide bolt carried by a channel-shaped housing adapted for recessed mounting into a side edge of a door or the like. An actuator tab on the slide bolt is exposed through a position control slot formed in the housing for fingertip actuation to displace the slide bolt between an advanced position engaging a keeper on an adjacent header or sill or the like to lock the door in a closed position, and a retracted position to permit door opening. The actuator tab has a slotted profile defining lock shoulders biased by a spring for releasibly engaging and locking with the housing at opposite ends of the position control slot, and a narrowed central slide track for alignment with the position control slot upon fingertip depression of the actuator tab to permit quick and easy sliding displacement of the actuator tab along the position control slot from one end to the other.
