Symmetrical and reversible-clutch mortise lock

A symmetrical and reversible-clutch mortise lock comprising:

• a central follower,
• a pair of symmetrical lateral followers, each one located on one side of the central follower,
• a spacer which makes the motion of the two lateral followers independent, and
• a motor, joined to a transmission system which engages with a toothed end of an actuation lever that is fixed, and able to rotate, on a support of the lock structure,
• wherein the lock further comprises:
• an accumulator arm, able to move linearly over the lock structure activated by the actuation lever, that comprises a pair of forks, with an L-shaped configuration and with a base, in addition to a guide point and a guide groove which, respectively coupled to an additional guide groove and an additional guide point fixed to the support of the lock structure, configure the linear motion of the accumulator arm,
• a torsion accumulator spring, coupled to the actuation lever, comprising two legs between which a prismatic projection of the actuation lever and a push point of the accumulator arm are located, limiting the motion of the accumulator arm, and
• a clutch, housed in the accumulator arm, able to move integrally with it,
• wherein the lateral follower is configured to extract the clutch from the accumulator arm and move the clutch until it makes contact with a drag element of the central follower, so that a latch of the lock is activated, such that the clutch is free to be able to move both linearly and rotationally inside the lock.
