Abstract

An auxiliary door lock for a dead bolt lock includes a relatively flat rectangular housing for mounting on a door over the interior operating knob of the dead bolt lock; and an actuator slidable and rotatable in an opening in a front wall o f the housing. The actuator includes a hollow handle, which is used to rotate the knob. Teeth on the actuator mesh with teeth in the housing in one position of the actuator so that the latter and the knob cannot be rotated when the door is locked. Thus, even using a key, someone outside of the door cannot unlock the dead bolt lock. By pushing the actuator into the housing to a second position, the teeth are disengaged and the actuator can be rotated to unlock the dead bolt lock.

Claims (3)

1. An auxiliary lock for use on the interior operating knob of an exterior key-operated dead bolt lock comprising:
(a) housing means for mounting on the inside of a door over the operating knob of a dead bolt lock;
(b) an opening in said housing means;
(c) actuator means for slidable mounting in said opening and on the knob of a dead bolt lock;
(d) first teeth means in said housing means; and (e) second teeth means on said actuator means for cooperating with said first teeth means to lock said operating lock in a locked position, whereby, when the actuator means is in a first, locked position in the housing means, the actuator means and the dead bolt lock knob cannot be rotated to unlock. the door, and when the actuator means is in a second, unlocked position in the housing means, the actuator means and the operating knob can be rotated to unlock the door.
2. The auxiliary lock of claim 1, including resilient arm means on said actuator means; and groove means in said housing means for receiving said arm means to releasably lock said actuator means in the locked or unlocked position.
3. The auxiliary lock of claim 2, wherein said actuator means includes hollow handle means for slidable mounting on the operating knob of a dead bolt lock; and rib means in said handle means for gripping the sides of an operating knob, whereby portions of the rib means can be removed to adapt the handle means to a variety of dead bolt lock knobs.
