Abstract

A card lock and key lock assembly includes a housing, a lock latch movably disposed in the housing, a swivel member pivoted to the housing and having a block portion stoppable against the lock latch, a card key lock disposed in the housing and having a lifting plate, a rotating shaft, and a hook plate connected with the lifting plate and engagable with the rotating shaft for driving the rotating shaft to rotate when the lifting plate is moved downwards, such that the rotating shaft is stoppable against the swivel member for driving the block portion of the swivel member to move away from the lock latch, and a pin tumbler lock disposed in the housing and having a plug with an arm portion for driving the block portion of the swivel member to move away from the lock latch when the plug is rotated to an unlocked position.

Claims

1. A card lock and key lock assembly comprising:

a housing having a chamber, a lock notch in communication with the chamber, and a pin tumbler lock hole in communication with the chamber;

a lock latch movably mounted in the housing and having a post movable in and out of the lock notch of the housing, and a spring stopped against the post to support the post in the lock notch;

a swivel member pivotally mounted in the housing and having a first block portion, a second block portion, and a third block portion, the swivel member being turnable between a first angular orientation where the first block portion is stopped against the lock latch for prohibiting the movement of the lock latch, and a second angular orientation where the first block portion is moved away from the lock latch for allowing the movement of the lock latch;

a card key lock disposed in the housing and including a lifting plate moveable upwards and downwards, a rotating shaft having a teeth portion and a claw portion, and a hook plate connected with one side of the lifting plate and engagable with the teeth portion of the rotating shaft when the lifting plate is moved downwards for driving the rotating shaft to rotate in a way that the claw portion of the rotating shaft is stoppable against the second block portion of the swivel member for driving the swivel member to turn to the second angular orientation; and

a pin tumbler lock having a casing mounted in the pin tumbler lock hole of the housing, and a plug rotatably disposed in the casing and provided with an arm portion stoppable against the third block portion of the swivel member for driving the swivel member to turn to the second angular orientation when the plug is rotated to an unlocked position.

2. The card lock and key lock assembly as claimed in claim 1, further comprising a torsion spring attached to the swivel member for keeping the swivel member in the first angular orientation.

3. The card lock and key lock assembly as claimed in claim 1, wherein the claw portion of the rotating shaft is stoppable against a visually accessible member movably mounted in the housing and having two different color zones, one of which indicates the locked condition of the card key lock and the other of which indicates the unlocked condition of the card key lock;

a spring is disposed in the housing and stopped against the visually accessible member to push the visually accessible member toward the rotating shaft for showing one of the color zones.

4. The card lock and key lock assembly as claimed in claim 1, wherein the rotating shaft is rotatably inserted into a retaining base.

5. The card lock and key lock assembly as claimed in claim 1, wherein the lock latch includes a push button, and a rod inserted into the push button and having an extension wall for connection of the post.
