Abstract: A surface-mountable electric strike having a keeper arranged to pivot about a first shaft extending in a longitudinal direction; a lock lever for locking the keeper in a door-locking position, the lock lever being arranged to pivot about a second shaft extending in a direction that is transverse to the longitudinal direction and parallel to the backside of the strike; and an actuation mechanism for actuating the lock lever, the actuation mechanism comprising an electromagnet that is situated next to the lock lever in a direction which is substantially perpendicular to the backside of the strike thereby enabling the electromagnet to act directly upon the lock lever providing a simple construction. Moreover, the orientation of the second shaft enables arranging the lock lever, and the electromagnet, above and/or underneath the keeper, thereby reducing the total depth of the strike.

Abstract: An electric strike having two keepers arranged to pivot about respective shafts extending in a longitudinal direction, a lock lever for locking the keepers in a door-locking position, the lock lever being arranged to pivot about a second shaft extending in a direction that is transverse to the longitudinal direction and parallel to the backside of the strike; and an actuation mechanism for actuating the lock lever. The keepers form side walls of a bolt cavity and are arranged to pivot between a door-locking position and a door-releasing position. Therefore, the bolt may exit the cavity in two directions, e.g., a first direction for a left-handed closure member and a second direction for a right-handed closure member. The strike can thus be mounted in the same orientation for both left-handed and right-handed closure members.

Abstract: A closing device includes an actuator mechanism and a hydraulic damper mechanism. The actuator mechanism includes a pushrod urged by a resilient member towards its extended position. The hydraulic damper mechanism includes a piston, a first rack and pinion gearing for converting the translational motion of the pushrod into a rotational motion of a first pinion, a transmission, which includes a second rack and pinion gearing, between the first pinion and the piston for transmitting and converting the rotational motion of the first pinion into a translational motion of the piston, a one-way valve allowing fluid flow from a first side to a second side of the cylinder cavity when opening the hinged member, and a restricted fluid passage between the first and second sides of the cylinder cavity.

Abstract: A closing device includes a torque storing mechanism, a first and a second actuation member which are both rotatable with respect to the supporting frame and a mechanical connector piece which is rotatable with respect to the supporting frame and configured for being mechanically fixed to the second hinge member which is fixed to the closure member. A first locking mechanism enables to lock the mechanical connector piece either to the first actuation member or to the second actuation member and a second locking mechanism enables to lock the supporting frame to the second actuation member when the connector piece is locked to the first actuation member and to the first actuation member when the connector piece is locked to the second actuation member. In this way, the closing device is suited for left and right turning closure members without requiring an extra gearing to reverse the rotation direction.

Abstract: A control assembly for controlling rotation of a turnstile, includes a torque-restoring mechanism (13) with springs (20), a motion converting transmission with a multiplying gearing (56, 57) converting a rotation of the turnstile over 120° into a rotation of the rotary shaft entering the hydraulic damper (26) over 180°. The hydraulic damper (26) has two pistons mounted onto a single piston rod. A cam or crank mechanism converts rotation of the rotary shaft into reciprocating motion of the two pistons. The first piston damps the rotary movement of the turnstile when moving in one direction while the other piston damps this movement when the pistons move in the other direction, therefore damping the turnstile in both directions. A motion converting transmission in combination with a double-piston mechanism avoids any loss of hydraulic fluid, while achieving a gradually increasing damping force to effectively stop the rotation of the turnstile.
