Abstract
A lock defining a rotating axis and for being installed on a door includes a first handle set, a second handle set, a transmission element and a latch mechanism. The first handle set is disposed on a side of the door and includes a first handle and a first tubular element. The second handle set is disposed on another side of the door and includes a second handle, a cylindrical element, a movable element and a second tubular element. The second tubular element is independent from the first tubular element. The transmission element has a first end connected to the first handle set and a second end connected to the movable element. The latch mechanism is disposed between the first handle set and the second handle set and includes a latch tongue driven by the first tubular element or the second tubular element.
Claims16
A lock defining a rotating axis and for being installed on a door, the lock comprising:
- a first handle set disposed on a side of the door, the first handle set comprising:
- a first handle;
- and
- a first tubular element connected to the first handle in a manner that the first tubular element and the first handle are capable of moving synchronously;
- a second handle set disposed on another side of the door, the second handle set comprising:
- a second handle;
- a cylindrical element disposed in the second handle, the cylindrical element comprising a guiding track, the guiding track having an unlocked end and a locked end opposite to the unlocked end;
- a movable element disposed in the cylindrical element in a manner that the movable element is capable of moving along the guiding track;
- and
- a second tubular element connected to the second handle in a manner that the second tubular element and the second handle are capable of moving synchronously, the second tubular element being independent from the first tubular element;
- a transmission element having a first end and a second end opposite to the first end, the first end being connected to the first handle set, the second end being connected to the movable element;
- and
- a latch mechanism disposed between the first handle set and the second handle set, the latch mechanism comprising a latch tongue driven by the first tubular element or the second tubular element;
- wherein when the cylindrical element is operated to move along the rotating axis and towards the first handle set, the movable element is driven to move from the unlocked end to the locked end to drive the transmission element to rotate, such that the lock is switched from an unlocked state to a locked state;
- wherein when the second handle is operated to rotate along a first direction, the cylindrical element is driven to rotate, and the movable element is driven to move from the locked end to the unlocked end to drive the transmission element to rotate, such that the lock is switched from the locked state to the unlocked state.
