Abstract

An interlocked double-unlockable lock apparatus including at least two unlocking modules. The unlocking modules are able to independently unlock the lock apparatus. The unlocking modules are at least partially interlocked with each other in a locked state. When any of the unlocking modules is unlocked, the two unlocking modules are released from each other to unlock the lock apparatus.

Claims

1. An interlocked double-unlockable lock apparatus comprising:

a lock body;

a locking member disposed on the lock body; and

at least two unlocking modules, any of the at least two unlocking modules being able to drive the locking member to unlock the lock apparatus, the at least two unlocking modules being at least partially interlocked with each other in a locked state, and when any of the at least two unlocking modules is unlocked, the two at least two unlocking modules are released from each other to unlock the lock apparatus.

2. The interlocked double-unlockable lock apparatus as claimed in claim 1, wherein:

the locking member is a teeterboard latch plate disposed on a female fastener, a numeral unlocking unit being disposed on the latch plate for pushing a movable member disposed on the latch plate, the movable member being supported by a support member disposed on a seat body, whereby the movable member cannot be pressed down to unlock the lock apparatus, when the numeral unlocking unit is in an unlocked state, the movable member is released from restriction of the support member to form one of the unlocking modules, a key-unlocked unit being disposed on the female fastener, such that, when the key-unlocked unit is in an unlocked state, the support member is displaceable to release the movable member so as to form another unlocking module.

3. The interlocked double-unlockable lock apparatus as claimed in claim 2, wherein the key-unlocked unit comprises a lock core seat, and a locating block, an outer end of the lock core seat being formed with a key hole, an inner end of the lock core seat having a lock core coupled with one end of the support member for controlling rotation of the support member another end of the support member being pivotally connected with the locating block.

4. The interlocked double-unlockable lock apparatus as claimed in claim 2, wherein the numeral unlocking unit comprises a numeral wheel set and a driving rod driven and controlled by the numeral wheel set, the driving rod being resiliently extensibly fitted in the numeral wheel set, a press end of the driving rod resiliently extending out from a hole of a lock casing, the movable member touching the press end, whereby the movable member is controlled between unlocking/locking states.

5. the interlocked double-unlockable lock apparatus as claimed in claim 2, wherein the movable member has a push plate, whereby one end of the push plate is engaged on the support section of the support member.

6. The interlocked double-unlockable lock apparatus as claimed in claim 2, wherein the movable member has an abutting post extending toward the press end of the driving rod for pushing the press end.
