    Abstract: The invention relates to a method, and to an arrangement, for optimizing the operation of a door closer at different phases of opening and closing of the door. The door closer is provided with a force transmission shaft (1) turning in accordance with the movements of the door and with a spring element (2) operationally connected thereto. The opening of the door takes place against the force of the spring element (2). According to the invention, at the closing phase of the door the energy of the spring element (2), exceeding the return force of the spring element (2) needed to accomplish the desired closing movement of the door, is recovered through simultaneous braking of the closing movement of the door for the main part of the closing movement. When the door is only somewhat open any more, preferably under 5.degree., a final force securing the closing of the door is accomplished by making use of said recovered energy. For putting the method into practice, the door closer is provided with rotor (4), stator (5) and energy storing device (7), arranged to serve as an electric generator or as an electric motor as required.

    Abstract: An automatic door for large-sized refrigerators, etc. is comprised of a door panel slidably supported by a stationary horizontal guide rail, a double-acting horizontal piston-cylinder unit for sliding the door panel along the guide rail for opening or closing the front opening of the refrigerator, and tightening units for tightening the door panel against a refrigerator panel when the door panel is in the closure position. The double-acting piston-cylinder unit is freed of pressure when the door panel is in the closure position so that the door panel is maintained in the latter position solely by the tightening pressure of the tightening units this pressure selected so as to be sufficiently small enough to be overcome by manual pressure if the need arises and yet still maintain the door panel in a hermetically sealed position against the refrigerator panel.

    Abstract: A sliding wing door, as used in railway and similar installations, is disclosed, of the kind in which the door, as it is opened, is first thrust out of its doorspace and slid alongside the vehicle body, the improvement consisting in that one of the component parts of the telescopable guide of the door panel is secured to the movable members of at least two linear ejectors intended to thrust the door panel out of the doorspace. Advantageously, the axes of the two (or more) linear ejectors are inclined through an angle of from 45.degree. to 90.degree. relative to the door space plane. A vertical shaft, mounted parallel and adjacent to the door post provides the initial movement of the door in a direction parallel to the ejector axes: the angle of rotation of the shaft is appropriately limited consistently with the necessity. Certain translation movements of component parts of the mechanism are aided by sets of rollers sliding on specially provided rolling paths.

    Abstract: A refrigerator includes a cabinet which has a storage space; a door which opens and closes the storage space; a hinge which connects the door and the cabinet and supports the door so that the door is capable of rotating; and a damping device which is provided on one side where the hinge is mounted and provides a damping force to the door when the door rotates in a closing direction, in which the damping device consists of an oil damper, and a contact surface is formed on one side corresponding to the damping device, with which the door starts to be in contact and thus to which a damping force is transmitted, at a set angle or less, and which is separated from the damping device when the door is opened.

    Abstract: An exemplary method relates to operating a door closer assembly including a closer body, a pinion rotatably mounted to the closer body, a motor including a motor shaft, and a bidirectional clutch connected between the pinion and the motor shaft. The method generally involves permitting, by the clutch, rotation of the pinion in each of a first direction and a second direction without transmitting rotation of the pinion in either direction to the motor shaft; sensing, with a sensor, a rotational position of the pinion; comparing, by a controller, the rotational position of the pinion with a desired rotational position; based upon the comparing, driving the motor to rotate the motor shaft; and by the clutch, coupling the motor shaft with the pinion in response to rotation of the motor shaft, thereby transmitting torque from the motor shaft to the pinion and urging the pinion toward the desired rotational position.

    Abstract: A drive for a rotatable wing, the drive including an electric motor, a transmission, an output shaft, which is coupled to the electric motor by means of the transmission and can be coupled to the wing in order to move the wing between a closed position and an open position by means of the electric motor, and a force device for applying a force to the output shaft. The drive can have a compact design in that the force on the output shaft produces a torque that has a threshold value which must be overcome in the currentless state of the electric motor in order to move the wing from the closed position to the open position and that disappears in the open position of the wing, and/or in that the force device has a spring arranged transversely to the axis of the drive shaft of the electric motor and transversely to the axis of the output shaft.
