Claims15
A lock for a closure comprising:
- a locking element which is movable in a locking element moving direction;
- and
- an input for moving the locking element between an unlocked position for placing a lock into an unlocked condition and a locked position for placing the lock into a locked condition,
- wherein the input is arranged movable in an input movement direction,
- wherein the lock includes a blocked condition in which the locking element is blocked relative to movement in the locking element moving direction,
- wherein the locking element is arranged at an output which is arranged movable in an output movement direction and which is connected to the input at least in the blocked condition through a first form locking engagement,
- wherein the first form locking engagement is configured, so that it transfers no movement between the output moving in the output movement direction and the input moving in the input movement direction,
- wherein a second form locking engagement or friction locking engagement is provided between the input and the output for providing a movement transfer between the output moving in the output movement direction and the input moving in the input movement direction,
- wherein the second form locking engagement or friction locking engagement is not provided at least in the blocked condition, so that a blocking of the lock is caused at least in the blocked condition,
- wherein the lock is movable from the unlocked condition into the locked condition and from the locked condition into the blocked condition respectively through a continuous movement of the input, and
