DOOR-STRIKE
The invention discloses a door opener for a door having a wing pivotally mounted to a door frame, said door opener comprising:a main body;a door opener latch hingedly mounted in the main body and pivotable between a closed position and an open position;a blocking member that is displaceable from a locking position into a release position and back, the blocking member in its locking position forming a stop for the door opener latch in the closed position to prevent pivoting of the door opener latch into the open position, and the blocking member in its release position being so far offset from the door opener latch that the door opener latch may be pivoted from the closed position to the open position and back without any restriction of movement by the blocking member;andan actuator coupled with the blocking member for releasing or locking the door opener latch.The actuator comprises a motor having a rotatable shaft supporting a worm thread, and a spring member having two end portions is provided, wherein a first end portion of the spring member engages with the worm thread in order to displace the spring member linearly in the direction of extension of the rotatable shaft by rotating the worm thread, and wherein a second end portion of the spring member is coupled with the blocking member.
