Abstract
Locks for storage containers having closures such as doors, covers or lids are disclosed. The lock is mounted to she closure and is latched in such a manner as to selectively prevent opening or removal of the closure. The latch of the lock can engage a slot in the storage container, a bracket on the storage container, or a strike on the storage container. Alternatively, the latch can engage a mounting bracket on the door or other portion of the door to selectively block movement of a handle for the door. Further, the latch can have a locking device which can selectively block movement of the latch. Movement of the locking device can be selectively controlled by a magnetic key.
Claims12
A lock for mounting on a storage container having a strike element and at least one of a door, a lid or a cover, the lock comprising:
- a housing;
- a latch operatively mounted on the housing, the latch being selectively positionable in a latched position into engagement with the strike element and an unlatched position out of engagement with the strike element;
- a locking device mounted in the housing, the locking device selectively positionable in a locked position and an unlocked position, wherein the locking device selectively locks the latch in the latched position;
- a locking device spring for biasing the locking device to the locked position;
- at least one locking element on the locking device, wherein the at least one locking element selectively engages the housing to lock the locking device in the locked position;
- at least one locking element spring for biasing the at least one locking element to a blocking position, wherein the at least one locking element includes magnetically-sensitive material;
- wherein when the latch moves from the unlatched position to the latched position, the locking device is adapted to move from the unlocked position to the locked position in contact with a surface of the latch to prevent the latch from moving from the latched position to the unlatched position;
- and wherein when the locking device moves from the unlocked position to the locked position, the at least one locking element is adapted to move to the blocking position in contact with the housing.
A lock for mounting on a storage container having a door and a strike, the lock comprising:
- a housing;
- a rotor latch operatively mounted in the housing;
- a first spring in the housing for biasing the rotor latch to an unlatched position;
- a locking slider for selectively locking the rotor latch in a locked position;
- a second spring in the housing for biasing the locking slider in a locked position;
- at least one spring-biased magnetic element operatively mounted to the locking slider and selectively engaging at least one profile of the housing;
- wherein when the door is shut, the rotor latch contacts the strike and moves from the unlatched position to a latched position;
- and
- wherein when the rotor latch moves from the unlatched position to the latched position, the locking slider moves from an unlocked position to a locked position contacting a surface of the rotor latch and preventing the rotor latch from moving from the latched position to the unlatched position;
- and wherein when the locking slider moves from the unlocked position to the locked position, the at least one spring-biased magnetic element moves from an unblocking position to a blocking position in contact with the at least one profile of the housing.
