Abstract

Abstract There is provided an improved projecting bolt assembly for flush mounting within the edge of a door and including a combination stile cap and bolt member slidably mounted in a channel in the edge of the door. An actuating lever is adapted to be pivotally mounted adjacent one of its ends, and a leaf spring is provided having one end rigidly secured to the combination stile cap and bolt member, and having its other end pivotally mounted to the actuated lever intermediate its ends. A double acting bolt assembly may be provided by pivotally securing the actuating lever to a second bolt member.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 148 words
A projecting bolt assembly for a door comprising: a bolt member adapted to be slidably mounted for projection into a locked position and withdrawal into an unlocked position; an actuating lever adapted to be pivotally mounted adjacent one end; and a leaf spring having one end cantilevered to said bolt member and having the other end pivotally mounted on said lever intermediate its ends, said spring being generally elongated and depressed intermediate its length to define a clearance recess for gripping said lever; whereby actuation of said lever against the restraining bias of said spring between a position toward said bolt member and a position away from said bolt member is effective to slide said bolt member between said locked and said unlocked positions; said leaf spring being bifurcated adjacent said other end providing a slot for clearance for the pivoting of said lever toward said bolt member.
Claim 2
Dependent Claim 148 words
A projecting bolt assembly for a door comprising: a bolt member adapted to be slidably mounted for projection into a locked position and withdrawal into an unlocked position; an actuating lever adapted to be pivotally mounted adjacent one end; and a leaf spring having one end cantilevered to said bolt member and having the other end pivotally mounted on said lever intermediate its ends, said spring being generally elongated and depressed intermediate its length to define a clearance recess for gripping said lever; whereby actuation of said lever against the restraining bias of said spring between a position toward said bolt member and a position away from said bolt member is effective to slide said bolt member between said locked and said unlocked positions; said leaf spring being bifurcated adjacent said other end providing a slot for clearance for the pivoting of said lever toward said bolt member.
Claim 3
Dependent Claim 53 words
A projecting bolt as set forth in claim 1 wherein said lever is provided with an enlarged end portion wider than said slot defining a gripping end, and wherein said spring is preloaded to bias said lever into said slot, said enlarged end portion forming a stop for the travel of said lever.
Claim 4
Dependent Claim 159 words
A projecting bolt assembly for a door comprising: a first bolt member adapted to be slidably mounted for projection into a locked position and withdrawal into an unlocked position; an actuating lever adapted to be pivotally mounted adjacent one end; a leaf spring having one end cantilevered to said bolt member and having the other end pivotally mounted on said lever intermediate its ends; whereby actuation of said lever against the restraining bias of said spring between a position toward said bolt member and a position away from said bolt member is effective to slide said bolt member between said locked and said unlocked positions; and a second bolt member adapted to be slidably mounted for projection in an opposed direction to the first mentioned bolt member into a locked position and withdrawal into an unlocked position, said actuating lever being pivotally mounted solely to said leaf spring and to said second bolt member at its said one end.
Claim 5
Dependent Claim 159 words
A projecting bolt assembly for a door comprising: a first bolt member adapted to be slidably mounted for projection into a locked position and withdrawal into an unlocked position; an actuating lever adapted to be pivotally mounted adjacent one end; a leaf spring having one end cantilevered to said bolt member and having the other end pivotally mounted on said lever intermediate its ends; whereby actuation of said lever against the restraining bias of said spring between a position toward said bolt member and a position away from said bolt member is effective to slide said bolt member between said locked and said unlocked positions; and a second bolt member adapted to be slidably mounted for projection in an opposed direction to the first mentioned bolt member into a locked position and withdrawal into an unlocked position, said actuating lever being pivotally mounted solely to said leaf spring and to said second bolt member at its said one end.
Claim 6
Dependent Claim 45 words
A projecting bolt assembly as set forth in claim 3 wherein each of said bolt members is provided with guide grooves, and additionally including projecting means extending into said guide grooves defining stops to insure operation of both bolt members upon actuation of said lever.
