Lock set to deadbolt interlock
First Claim
Patent Images
1. A door lock arrangement comprising:
- a deadbolt having a deadbolt latch, and a deadbolt cam for being turned to actuate said deadbolt latch;
a door lock set having a latch, and a handle to actuate said door lock latch;
a biometric sensor for sensing aspects of an individual wishing access to a building associated with said door lock arrangement, and a control comparing the sensed aspects with stored aspects to identify a user as an approved individual;
an interlock for selectively actuating said deadbolt latch when said handle is actuated under certain conditions; and
said interlock being moved to a position where it can actuate said deadbolt latch when said handle is actuated when said control senses that the individual is an approved individual.

Abstract
An interlock is provided such that when a standard door lock handle is actuated, it will also open a deadbolt. The interlock is normally in a non-operational position. When a biometric sensor senses that a user wishing to use the door is approved, the interlock is actuated. The use of the interlock saves user movement by allowing the deadbolt to be opened with simple actuation of the standard lock structure.

10. An interlock structure for selectively interlocking a door lock set with a deadbolt such that actuation of a handle for the door lock set will also actuate the deadbolt comprising:
-
an interlock actuation structure for selectively actuating a deadbolt cam when a lock handle is turned; and
an interlock cam for selectively actuating said interlock structure, said interlock cam being in a first position when an approved individual has not been identified by a biometric sensor associated with the interlock structure, said interlock cam not actuating said interlock actuation structure when in said first position, and said interlock cam being movable to a second position at which it will actuate the interlock actuation structure, said interlock cam being driven to the second position when an approved individual has been identified such that turning movement of the handle will actuate the deadbolt. - View Dependent Claims (11, 12, 13, 14, 15, 16)
