Abstract
a device allowing engagement of a conventional keyed deadbolt lock tumbler assembly without use of a key is provided. The device is assembled around the tumbler assembly and is fitted into a standard door lock cut-out. The device includes a rotatable ring extending substantially around the periphery of the device. At rest the rotatable ring is biased in an original starting position. Upon overcoming the bias, the rotatable ring is moved to a second engaging position in which the deadbolt is projected into an engaged position. Upon release of the rotatable ring the ring is biased back to the original position, while at the same time the deadbolt remains engaged. The biasing back of the device prevents the lock from binding or jamming.
Claims1
A keyless deadbolt lock engaging apparatus for use with a conventional deadbolt assembly, the apparatus comprising:
- an actuator means to engage the deadbolt assembly, the actuator means including of a radial actuator engaging the deadbolt assembly and further including an arm member;
- a rotational means the rotational means including a rotatable ring having an inwardly projecting center projection capable of operatively engaging the arm member, the rotational means capable of rotating from a first position whereby the actuator means is moved to a deadbolt disengaged position to a second position whereby the actuator means is in a deadbolt engaged position;
- and
- a biasing means to return the rotational means from a second position to the first position while the actuator means remains in the deadbolt engaged position, the biasing means including the combination of a spring ring proximate the rotational means and movable with respect to the rotational means and a spring member associated with the ring whereby the spring member returns the rotational means from the second position to the first position.
