Abstract
Here is provided a device for securing a standard deadbolt lock in a locked orientation so that the deadbolt lock cannot be unlocked by an intruder. The device disclosed includes an elongated member pivotally coupled to a base member by a pivotal joint. The base member is securely mounted to a housing of the deadbolt lock and the protruding member has an elongated groove dimensioned and configured to receive the latch of the deadbolt lock and secure it within the groove such that the latch cannot be rotated to unlock the deadbolt lock. The protruding member is pivotally movable between a closed position wherein the latch is contained within the groove and an extended position wherein the protruding member is positioned away from the latch.
Claims16
A combination comprising:
- a deadbolt lock assembly comprising a lock housing, a bolt slidingly received in said lock housing, a latch rotatably mounted to said lock housing and movable between a locked position and an unlocked position, and a locking mechanism coupled to said latch and said bolt which moves said bolt between an extended position and a retracted position in response to rotation of said latch;
- a securing device which releasably secures said latch in said locked position, said device comprising:
- a base portion operatively connected to said lock assembly;
- an elongated portion adapted to engage said latch;
- and a hinge mechanism which allows pivotal movement of said base and elongated portions with respect to each other;
- said elongated portion comprising a pair of substantially parallel fingers separated by an elongated groove which can receive said latch therein;
- each of said fingers having a first end attached to said hinge mechanism and a terminal free end unconnected to any other structure and terminating in a tip spaced furthest from said hinge mechanism said terminal free end tip having a curvature towards said lock assembly when said latch is within said groove between said fingers, said free end tip curvature ensuring good contact with said lock assembly base portion to prevent inadvertent rotation of said latch;
- and
- wherein said securing device consists of said base portion, elongated portion, and hinge mechanism and wherein said elongated portion consists of said fingers.
A combination comprising:
- a deadbolt lock assembly comprising a lock housing, a bolt slidingly received in said lock housing, a latch rotatably mounted to said lock housing and movable between a locked position and an unlocked position, and a locking mechanism coupled to said latch and said bolt which moves said bolt between an extending position and a retracted position in response to rotation of said latch;
- a securing device which releasably secures said latch in said locked position, said device comprising:
- a base portion operatively connected to said lock assembly;
- an elongated portion adapted to engage said latch;
- and a hinge mechanism which allows pivotal movement of said base and elongated portions with respect to each other;
- said elongated portion comprising a pair of substantially parallel fingers separated by an elongated groove which can receive said latch therein, each of said fingers having a first end attached to said hinge mechanism and a terminal free end unconnected to any other structure and terminating in a tip spaced furthest from said hinge mechanism;
- wherein said hinge mechanism provides a consistent biasing force to retain said elongated portion both in a first position wherein said latch is received in said groove between said fingers, and a second position wherein said latch is not received in said groove between said fingers;
- and
- wherein said biasing force is provided by a friction bushing component of said hinge mechanism, and wherein said securing device consists of said base portion, elongated portion, and hinge mechanism;
- and wherein said elongated portion consists of said fingers.
A securing device moveable between first and second positions operatively engaging or releasing, respectively, a rotatable dead bolt latch, said device consisting of:
- a base portion;
- an elongated portion adapted to engage a dead bolt latch;
- and a hinge mechanism which allows pivotal movement of said base and elongated portions with respect to each other;
- said elongated portion consisting of a pair of substantially parallel fingers separated by an elongated groove which can receive a deadbolt latch therein in said first position, each of said fingers having a first end attached to said hinge mechanism and a terminal free end unconnected to any other structure and terminating in a tip spaced furthest from said hinge mechanism.
