Electromechanical lock

An electromechanical lock, comprising:

• an electromechanical locking mechanism for locking an associated counter-piece that adopts an open position or a closed position relative to the locking mechanism;
• and
• a control circuit,
• wherein the electromechanical locking mechanism has a latch, an entrainer that is rotatable about an axis of rotation for driving the latch, and an electric motor for driving the entrainer,
• wherein the latch is moveable between a locking position, in which the latch locks the associated counter-piece located in the closed position, and an unlocking position, in which the latch releases the associated counter-piece for the open position, wherein the latch is preloaded in the direction of the locking position,
• wherein the entrainer is selectively rotatable into a release position, a standby position, and a blocking position by way of the electric motor,
• wherein, by rotating the entrainer into the release position, the latch is driven by way of the entrainer to perform a movement from the locking position into the unlocking position,
• wherein, in the standby position of the entrainer, the latch is released to be urged back against the preload from the locking position, and
• wherein, in the blocking position of the entrainer, the entrainer blocks the latch against a movement from the locking position in the direction of the unlocking position,
• wherein the control circuit controls the electric motor to drive the entrainer into the release position, the standby position, and the blocking position,
• wherein the release position and the blocking position correspond to the same angular position of the entrainer and differ from one another with respect to the direction of rotation in which the entrainer is rotated, starting from the standby position, in order to set either the release position or the blocking position.

• wherein, in the blocking position of the entrainer, the entrainer blocks the latch against a movement from the locking position in the direction of the unlocking position,
• wherein the control circuit controls the electric motor to drive the entrainer into the release position, the standby position, and the blocking position,
• wherein the latch has a pivot lever pivotable about a pivot axis and an engagement section that is fastened to the pivot lever and that locks the associated counter-piece, which is located in the closed position, in the locking position of the latch,
• wherein the latch is moveable by a pivot movement of the pivot lever about the pivot axis from the locking position into the unlocking position,
• wherein the pivot lever has a contact section, and wherein the entrainer has a blocking section, wherein the blocking section engages behind the contact section in the blocking position and blocks the pivot movement of the pivot lever by the engagement behind,
• wherein, in the blocking position, the entrainer has a receiver for the contact section that is bounded at least at three sides,
• wherein the blocking section forms a first boundary of the receiver, and
• wherein a second boundary of the receiver that is opposite the first boundary is formed by a guiding section which the contact section contacts,
• wherein the guiding section is connected to the blocking section by a third boundary of the receiver.
