Abstract: A closure sequence controller for a double door arrangement in which the double door arrangement is provided with a first door closer and a first pull arm for closing a first door leaf and with a second door closer and a second pull arm for closing a second door leaf. A guide rail guides the distal ends of the pull arms relative to the door closers. The closure sequence controller includes a connection piece for transmitting a pulling force from the distal end of the first pull arm to the closure sequence controller. The closure sequence controller prevents movement of the distal end of the second pull arm in the guide rail past the closure sequence controller until the distal end of the first pull arm has exerted the pulling force on the closure sequence controller through the connection piece.

Abstract: An electromechanical actuator comprises a body element and an elongated interaction element. One of the elements includes an electromagnet and the other ferromagnetic material or permanent magnet. The elements are arranged with respect to each other so that a rotational motion may be imparted to the interaction element by a magnetic field created by the electromagnet. The interaction element is rotatable between two rotational positions by changing the polarity of energization of the electromagnet. At one rotational position the interaction element is displaceable by an external force applied to one end in a direction along its rotation axis. The interaction element cooperates with the body element in a manner such that they together define the range of axial movement of the interaction element.

Abstract: A first door closer unit and a first swing arm close a first door leaf of a pair of door leaves arid a second door closer unit and a second swing arm close the second door leaf of the pair. A guide rail supported by a door frame guides the distal ends of the swing arms. A closure sequence controller includes a control member in the guide rail between the distal ends of the swing arms and movable against the force of a spring, a support element stationarily supported by the guide rail, and a movable blocking member. The closure sequence controller is arranged in cooperation with the distal ends of the swing arms at the end phase of the closing movement of the door leaves so that the blocking member prevents movement in the guide rail of the distal end of the second swing arm until the distal end of the first swing arm acts on the blocking member through the control member go that the blocking member allows closing of the second door leaf.

Abstract: First and second door leaves are pivotable with respect to a door frame and each door leaf has a hinge edge at which it is hingedly attached to the door frame. Each door leaf is provided with a door closer and a pull arm for closing the door leaf. The door frame is provided with a guide rail mounted to the door frame for guiding movement of distal ends of the pull arms longitudinally of the guide member. During closing movement of the second door leaf, the distal end of the second pull arm moves along the guide rail initially in an allowing direction, away from the hinge edge of the second door leaf, and subsequently in a blocking direction, towards the hinge edge of the second door leaf. During closing movement of the second door leaf, a blocking device allows movement of the distal end of the second pull arm past the blocking device in the allowing direction and selectively prevents return movement of the distal end of the second pull arm past the blocking device in the blocking direction.

Abstract: An electromechanical cylinder lock includes a lock body and a turnable lock cylinder and a locking mechanism inside the lock body. The locking mechanism normally prevents turning of the lock cylinder relative to the lock body and can be moved by a key of the lock to a releasing position allowing turning of the lock cylinder. The key for the lock includes a transmitter for transmitting an electronic code and the lock correspondingly includes a receiver for receiving and identifying the code of the key. When the receiver detects the correct code the receiver enables mechanical opening of the lock by the key. The lock includes a locking disc with a key opening which is so designed that the turning of the key does not directly act mechanically on the locking disc. The lock also includes a coupling element for coupling the locking disc to the turning movement of the key.

Abstract: A control device for a door closer is arranged to control flow of pressure medium within a body part of the door closer and comprises an adjustment member supported by threads on the body part of the door closer, and in cooperation therewith, a separate substantially hollow control member, which is arranged to restrict the flow of the pressure medium when necessary. Turning of the adjustment member with respect to the body part of the door closer brings about movement of the control member in the axial direction of the control device for providing the desired control. The control member is arranged to be attached to the adjustment member in the radial direction so that movement of the control member with respect to the adjustment member in the axial direction is prevented.
