Abstract
A high security locking system can be used in a conventional pivot door adapted for use with a latch and deadbolt lock combination. The high security system can be a multi-point lock, received in a recess formed in a locking edge side of a door stile, cooperating with a linkage or other mechanism in a conventional deadbolt/location. The lock can be actuated with a keyed cylinder and thumb turn combination.
Claims24
A door lock comprising:
- an elongate housing;
- a drive bar located substantially within the elongate housing and adapted for movement from a first vertical position to a second vertical position;
- a locking member engaged with the drive bar, the locking member adapted for movement from a retracted position to an extended position upon movement of the drive bar from the first vertical position to the second vertical position, wherein the locking member is located within the elongate housing when in the retracted position, wherein the locking member projects from the elongate housing when in the extended position, and wherein the locking member is adapted to engage a keeper when the locking element is in the extended position;
- a bar slide adapted for movement from a first position to a second position, wherein the bar slide is adapted to be actuated by a movement of a lever arm;
- a transmission for coupling movement of the bar slide with movement of the drive bar;
- and
- an insert housing connected to the elongate housing and defining a slot for receipt of the bar slide, wherein the bar slide is located at least partially within the insert housing.

A door lock comprising:
- a drive bar adapted for movement from a first position to a second position;
- a locking member connected to the drive bar, the locking member adapted for pivoting movement from a first position to a second position upon linear movement of the drive bar from the first position to the second position, and wherein the locking member is adapted to engage a keeper when the locking element is in the extended position;
- a bar slide adapted for movement from a first position to a second position, upon application of a force by a lever arm, wherein the bar slide comprises:
- a first end defining an opening for connection to the lever arm;
- and
- a second end pivotally connected to the transmission, wherein, from the first position of the bar slide to the second position of the bar slide, the first end moves in a substantially arcing direction and the second end moves in a substantially linear direction;
- and
- a transmission for coupling movement of the bar slide with movement of the drive bar, such that when the bar slide is in the first position, the drive bar is in the first position, and when the bar slide is in the second position, the drive bar is in the second position.

A door lock comprising:
- a drive bar adapted for movement from a first position to a second position;
- a pivot pin connected to the drive bar;
- a locking member connected to the drive bar via the pivot pin, the locking member adapted for pivotal movement from a first, refracted position to a second, extended position upon movement of the drive bar from the first position to the second position, and wherein the locking member is adapted to engage a keeper when the locking element is in the extended position;
- a bar slide adapted for movement from a first position to a second position, upon application of a force to the bar slide;
- a transmission for coupling movement of the bar slide with movement of the drive bar;
- a connection pin connecting the bar slide and the transmission;
- and
- a housing defining a slot for sliding receipt of the connection pin as the bar slide moves from the first position to the second position such that when the bar slide is in the first position, the drive bar is in the first position, and when the bar slide is in the second position, the drive bar is in the second position.
