Abstract: An electromechanical door lock comprises a lock body (1), in which is a dead bolt (3) which can be dead locked in its protruding position and electrically withdrawn into the lock body, a latch (4) which is spring loaded to be protruding from the lock body and which centralizes the dead bolt in an opening in a striking plate (18) arranged for the door lock, and force transmission means (8-14) for transmitting force from an electrical operating device (7) to the dead bolt (3). Said latch (4) includes in a way known as such a body member (4c) moveable inside the lock body to which is jointed a wedge-shaped member (4a, 4b), protruding at least partly out from the lock body when the latch is in the protruding position, so that the latch (4) can be pressed inside the lock body when a force acts on said wedge-shaped member (4a, 4b) from either side of the lock body in the direction of the door opening or closing. In addition the lock body includes separate dead locking means (15-17) for the latch, arranged to prevent the latch to be moved inside the lock body. Said force transmission means (8-14) include a force transmission unit (11) moveable at least substantially in the longitudinal direction of the lock body, the transmission movement of which is arranged to release the dead locking of both the dead bolt (3) and the latch (4).

Abstract: A door closer includes a body formed with a cylinder and a piston system located in the cylinder and functionally connectable to the door. The piston system divides the cylinder into a first cylinder volume on a first side of the piston system and a second cylinder volume on a second side of the piston system. A spring located in the second cylinder volume. A flow channel formed in the body guides flow of fluid from the first cylinder volume to the second cylinder volume, and a control valve for regulates rate of fluid flow through the flow channel. A filter is positioned across the flow channel upstream of the control valve relative to flow of fluid through the flow channel from the first cylinder volume to the second cylinder volume. The filter presents a filter area greater than the cross-sectional area of the flow channel to incoming flow to the filter and presents a filter area substantially equal to the cross-sectional area of the flow channel to outgoing flow from the filter.

Abstract: A door closer includes a body having an external surface and defining an interior space. The body is formed with a passage extending from the external surface of the door closer body and communicating with the interior space. A valve member is located in the passage between the interior space and the external surface of the door closer body. The valve member has a gasket groove and a gasket is fitted in the gasket groove. The gasket groove is configured to allow the gasket to protrude from the groove and/or break when the pressure in the interior space exceeds the pressure at the external surface by a predetermined amount and thereby allow door closer fluid in the interior space to escape from the door closer.

Abstract: A door closer includes a casing-like body enclosing a piston member, which is movable back and forth according to the movements of a door and is in cooperation with at least one closer spring, and a closer shaft and a pinion member connected thereto for transmitting the force of the movement of the door to the piston member. The pinion member is mounted on the closer shaft eccentrically with respect to its rolling curve. The piston member is casing-like and is provided with a toothing arranged at its inner surface. The rolling curve of the piston's toothing is at least substantially linear and is inclined relative to the axis of movement of the piston member. The pinion member is located inside the piston member in cooperation with the toothing of the piston member so that the force transmission moment of the pinion member is at its maximum in a position corresponding to the closed position of the door.
