Abstract
A lock mechanism is provided which may actuate both a deadbolt and flush bolts in response to a single lock movement. The mechanism includes a dual element bolt throw and flush bolt actuator, which locks in place in the extended position if the end of the bolt is pressed inwardly. The throw includes a transfer mechanism which transposes the horizontal movement of the bolt to vertical movement at the flush bolts. The flush bolts also include a mechanism to limit retraction thereof if the extending end of the flush bolt is exposed to inward directed force. The entire lock mechanism may be actuated by a standard cylindrical lockset having actuating jaws extending therefrom.
Claims32
A mechanism to secure a portion of the cover of an opening to a portion of the opening, comprising:
- a guide member having an extended position and a retracted position;
- a multiple piece bolt member disposed adjacent said guide member and interconnected to one end of said guide member;
- said multiple piece bolt member having a first plate and a second plate, said first plate and said second plate selectively moveable with respect to one another;
- said first plate including a slot therein;
- said second plate including a lock bar alignment member therein;
- a lock bar extending through said lock bar alignment member and into said slot in said first plate;
- said first plate having an extended position and a retracted position, said lock bar, when said first plate is located in said extended position, interferingly engaging said slot in said first plate to prevent movement of said first plate from said extended position to said retracted position without independent movement of said guide member to retract said first plate.
A lock mechanism, comprising:
- a turnable handle;
- a moveable member interconnected to said handle, said moveable member being linearly actuable in response to turning motion of said handle;
- a transfer member connected to said moveable member;
- at least one flush bolt connected to said transfer member;
- and
- said transfer member actuable in response to movement of said moveable member to a retracted position in response to turning motion of the turnable handle to move said flush bolt, said moveable member having a latch portion for being engaged to move said moveable member to said retracted position without the need to turn said turnable handle.
A lock member for securing a cover in an opening comprising:
- a rotatable handle;
- a guide member connected to said rotatable handle and positionable in an extended position and in a retracted position in response to rotational positioning of said rotatable handle;
- a first plate received in the door and positionable in an extended position and a retracted position;
- a second plate slidably affixed to said first plate and connected to said guide member to position said first plate in said extended position and said retracted position in response to movement of guide member;
- and
- a lock member selectively locking said first plate in said extended position.
A lock for use with a turnable handle having retractable jaws extending therefrom, comprising:
- a case;
- an actuating portion located at least partially within said case and moveable linearly within said case between an extended and a retracted position;
- a lock attachment portion extending outwardly of the case and connected to the retractable jaws on the exterior of the case;
- at least one rod received partially inwardly of said case and extending from said case to a flush bolt located adjacent one edge of the case;
- and
- a translation member located within said case and actuable in response to linear movement of said actuating portion to cause linear movement of said rod.
A lock mechanism, comprising:
- a turnable handle;
- a moveable member interconnected to said handle and linearly actuable in response to turning motion of said handle between at least a retracted and an extended position;
- a lockout member, releasable by turning motion of said handle, to selectively lock said moveable member in an extended position;
- a transfer member connected to said moveable member;
- at least one flush bolt connected to said transfer member;
- and
- said transfer member actuable in response to movement of said moveable member to move said flush bolt in response to turning motion of the turnable handle.
