Lock

A lock comprising:

• a locking mechanism having a latch that is movable between a latched position, which is provided for securing a counter-piece movable relative to the locking mechanism, and an unlatched position provided for releasing the counter-piece;
• an actuation element for manually moving the latch into the unlatched position;
• and
• a coupling element that can be transferred between a coupled state, in which it is coupled to the latch, and a decoupled state, in which it is movable relative to the latch, and that can be moved from a passive position into an active position by means of the actuation element,
• wherein the latch can be moved into the unlatched position by a movement of the coupling element, which is in the coupled state, from the passive position into the active position by the actuation element;
• wherein the latch has a guide section which is formed as a guide slot shaft in the latch and in which the coupling element is slidingly guided and movable in parallel with the latch.

• further comprising a blocking element that is adjustable between a blocking position, in which the latch is blocked in its latched position, and a release position in which the latch is movable into its unlatched position;
• further comprising a control element for selectively transferring the coupling element into the coupled state or the decoupled state, wherein the blocking element is formed at the control element.
