Lock assembly

Claim 1

A panic exit, multiple deadbolt, interconnecting door lock assembly comprising: a main lock subassembly including a latch bolt reciprocable between extended and retracted positions, a main lock security deadbolt reciprocable between extended and retracted positions, an outer hand operator, an inner hand operator, and an inner turnpiece; auxiliary lock subassemblies spaced from said main lock subassembly and each including a security deadbolt reciprocable between extended and retracted positions; first means for operably connecting said outer hand operator only to said latch bolt for reciprocating said latch bolt; second means for connecting said inner turnpiece to said main lock subassembly security deadbolt and to said auxiliary lock subassembly security deadbolts to simultaneously reciprocate all of said deadbolts, and including a rotational tailpiece; and third means for connecting said inner hand operator to said latch bolt and to all of said security deadbolts, to simultaneously reciprocate all of said deadbolts and said latch bolt; said third means including a vertically shiftable slide; a driver cam connected to said inner hand operator to be operated thereby, and in engagement with said slide to vertically shift said slide when operated by said inner hand operator; a one way drive latch driver engaged by said slide to retract said latch bolt; and a shiftable driven cam operably engaged with said slide to be shifted thereby; said main lock subassembly including a swivel to said main lock security deadbolt, said rotational tailpiece projecting through said swivel and through said driver cam to retract said main lock security deadbolt with vertical shifting of said slide; an auxiliary drive plate cam on said tailpiece to rotate therewith, and an auxiliary shiftable drive plate connected to said auxiliary drive plate cam to be shifted thereby and also connected to said reciprocable connecting means to said auxiliary lock subassemblies, to enable panic exit with retraction of all of said deadbolts by operation of just said inner hand operator which shifts said driven cam, to shift said vertically shiftable slide and thereby shift said driven cam, said rotational tailpiece, said main lock deadbolt swivel and also said auxiliary drive plate cam, and thereby said auxiliary drive plate, and said reciprocable connecting means to retract said auxiliary lock deadbolts.
