US 6,474,248 B1 · High security lock apparatus

Abstract

A high security lock apparatus comprises a deadbolt lock (70) having a lock body (71) and a deadbolt (73) extendible therefrom. A lock body support (67) cooperates with the lock body (71) to permit relative movement therebetween and has a deadbolt clearance opening (81) therein to receive the deadbolt (73) when aligned therewith. A doorbolt is operatively connected to the lock body support (67) and mounted for movement with respect to a complementary doorbolt stop in response to the relative movement. A tool receiver (77) cooperates with the lock body support (67) and receives an alignment tool (101) to generate the movement to align the deadbolt (73) with the deadbolt clearance opening (81) prior to extending the deadbolt (73). Preferably, the lock body (71) is journalled for rotation relative to the lock body support (67). The lock body support (67) preferably has an actuating arm (21, 22) extending therefrom and a doorbolt link extends from the actuating arm (21, 22) to the doorbolt to operatively connect them together to actuate the doorbolt. In this way, strength of the deadbolt itself does not effect overall strength of the high security lock apparatus.

Dependent claims

A high security lock apparatus for controlling the position of a moveable doorbolt with respect to a door, the lock apparatus comprising:

(a) a primary deadbolt lock having a primary lock body and primary deadbolt extendable and retractable relative thereto;
(b) a lock body support co-operating with the primary lock body to permit relative movement therebetween when the deadbolt is retracted, the lock body support having a deadbolt clearance opening therein to receive the deadbolt when extended and aligned therewith to prevent said relative movement, the lock body support being operatively connectable to the doorbolt to selectively extend or retract the doorbolt when the deadbolt is extended and the lock body is moved;
and
(c) a secondary deadbolt lock to interfere selectively with the lock body support to prevent movement thereof, the secondary lock having a secondary lock body and a secondary deadbolt extendable and retractable relative thereto, the secondary deadbolt being complementary to the clearance opening of the lock body support so that the secondary deadbolt can be selectively received therein to prevent movement of the lock body support.

1 more element

A high security lock apparatus for securing to an item, the apparatus comprising:

(a) a deadbolt lock having a lock body and a deadbolt extendable and retractable relative thereto;
(b) an inner ring member which is concentric with a main axis and is secured to the lock body to mount the lock body therewithin to essentially enclose the lock body;
(c) a lock body support comprising an intermediate ring member which is concentric with the main axis and co-operates with the inner ring member to permit unlimited relative rotation therebetween about the main axis in either direction when the deadbolt is retracted, the intermediate ring member having a deadbolt clearance opening therein to receive the deadbolt when aligned therewith and extended into the clearance opening to fix the lock body with respect to the lock body support to prevent said relative rotation;
(d) a first journal for journalling the lock body for rotation relative to the intermediate ring member, the first journal being disposed between the inner ring member and the intermediate ring member;
(e) an outer casing which is concentric with the main axis and co-operates with the intermediate ring member to permit relative rotation therebetween about the main axis, the outer casing essentially enclosing the intermediate ring member and being securable to the item;
and
(f) a second journal for journalling the intermediate ring member relative to the outer casing, the second journal being disposed between the intermediate ring member and the outer casing, the second journal being spaced radially outwardly from the first journal so as to substantially enclose the first journal.
