Appl. No.:

12/214821

Inventors:

Robert L. Willcox - Owasso OK, US

International Classification:

E05C 1/00

US Classification:

292163

Abstract:

A bolt mountable on adjacent members of a structure having a bolt assembly mountable on a first member of said structure and a keeper assembly mountable on a second member of said structure. A slide bolt is positioned to move slidably in a first channel in a slide block of bolt assembly which is aligned between the bolt assembly the keeper assembly to provide locking operation with a locking pin depending thru the keeper and is controllable from above keeper. The slide block includes a second channel in longitudinal connection with first channel, but not having entire lengthwise communication with the first channel in order to provide for compressibility. A coil spring is positioned in the second to react with the slide bolt, and a retainer depends from near one end of the slide bolt to provide compressibility for the coil as the slide bolt is locked. Upon release of the locking pin, the compressive force of the coil spring against the retainer forces the slide bolt to open forcefully,

Abstract:

A bolt mountable on adjacent members, such as a door and a door frame, to hold the members lockably secure, comprises a bolt assembly on a first member and a keeper assembly on the second member. The bolt assembly includes a flat, elongated slide bolt slidably therein. The slide bolt has a locking pin opening at one end to receive and hold securely a locking pin of the keeper assembly, and a control stem at the other end extending through a slot in the bolt to the exterior. A pair of shoulders at the end of the slide bolt define a narrow passageway communicating with the locking pin opening. A narrow stem is connected axially to the locking pin and extends through an opening in the keeper assembly cover to the exterior of the bolt. A coil spring below the locking pin urges the locking pin toward the exterior. To lock the bolt, the locking pin stem is depressed manually so that the stem may be aligned with the passageway of the slide bolt, the slide bolt is moved toward the locking pin, and the locking pin stem is released, permitting the coil spring to urge the locking pin into locking position within the locking pin opening.
