Abstract:
A control assembly for an outwardly opening pivoting wing, comprising an actuating device including a support, a crank rotatable with respect to the support and a control mechanism actuated by the crank, an arm having a toothed portion, wherein said control mechanism cooperates with the toothed portion of the arm for swinging the arm between a closed wing angular position and an open wing angular position.
Abstract:
A door operator system capable of detecting a current-time position of a movable barrier comprises a current-time position detecting device comprising a first gear, a first angular position sensing unit, a revolution counting unit and an arithmetic unit. The first gear is coupled to an output shaft of a motor or a winding shaft. The first angular position sensing unit is provided for detecting a first angular position of the first gear. The revolution counting unit counts the number of revolutions of the first gear. The arithmetic unit calculates a number of total circumferential intervals of the output shaft of the motor or the winding shaft based on D=(La*X)+A/(360/X), where D is the number of the total circumferential intervals, La is the number of revolutions of the first gear, A is the first angular position, X is a number of circumferential intervals per revolution of the first gear.
Abstract:
A folding door with two or more intrinsically rigid folding shutter elements with alternating noncollapsing and collapsing element edges, with at least one guide means which can be raised and lowered on or in one or more guide rail(s), for moving a, in particular the lower, permanently guide rail-adjacent, noncollapsing door element edge, wherein at least one release movement means, which is provided for the initial release movement of the permanently guide rail-adjacent door element edge from the guide rail(s), at the beginning of the opening of the folding door, and for the final advance movement of the permanently guide rail-adjacent door element edge at the end of the closing of the folding door, and an actuation device and method for the same.
Abstract:
An arrangement is disclosed for a meter cabinet, distribution cabinet or empty housing, including a frame and a door, wherein the frame can carry a door and the door is attached pivotally to the frame on its hinge side. The door may be aligned in relation to its frame quickly and without problems, with an adjustment device for aligning the door in the closed condition, the adjustment device being associated with the frame.
Abstract:
The invention relates to a furniture flap drive comprising an electric drive having an electric motor and a mechanical actuating unit having an actuating arm, the mechanical actuating unit and the electric drive being separate components and being releasably fastenable to each other. The actuating unit has a bearing in which the electric drive can be suspended, the suspended electric drive being swivelable about the bearing towards the actuating unit. A locking device is mounted at a distance to the bearing and can be used to lock the electric drive, in a preferably releasable manner, with the actuating unit once the latter has been swiveled open.
Abstract:
A device for controlling a door operated by a motor includes an opening/closing mechanism that opens and closes the door, and a gear mechanism that includes a plurality of tooth units each of which has different mesh and that conveys a torque of the motor to the opening/closing mechanism. The tooth units include a low-torque tooth unit that convey a relatively low torque, and a high-torque-tooth unit that conveys a relatively high torque. The torque conveyed to the opening/closing mechanism is changed by selecting a tooth unit based on a position of the door at the time of starting an opening or closing operation of the door.
Abstract:
The invention relates to a flap drive system for a flap which is movably mounted on a furniture carcass, the flap drive system being arranged on a sidewall of the furniture carcass. The flap drive system comprises: a mechanical actuating unit having an actuating arm that can be connected to the flap and an accumulator acting upon the actuating arm, an electric drive, fastened on the mechanical actuating unit, for driving the flap, said electric drive having at least one electric motor, and a gear stage which allows the transmission of force from the electric drive onto the mechanical actuating unit. The gear stage is designed as a separate component and has a housing that is independent from the mechanical actuating unit and the electric drive or an independent mounting plate.
Abstract:
Motorized split-hinge device for a very heavy double door, designed to be motorized and consisting of at least one flap or panel (1) that is mounted to pivot, around an essentially vertical axis of rotation, on a frame (2), comprising a stationary split-hinge part (3) that is integral with said frame (2) and a movable split-hinge part (4) that is integral with said flap (1) and mounted in rotation relative to said stationary split-hinge part (3) around a pivoting shaft.The movable split-hinge part (4) comprises a drive mechanism that is driven by a motor unit (7) that is able to drive said movable split-hinge part (4) in rotation around its pivoting shaft and starting said flap (1) moving by pivoting when opening or closing, whereby said motor unit (7), on the one hand, is mounted in a removable manner on said drive mechanism and on a stationary part (3) of said door, and, on the other hand, is kept in drive position of said mechanism with anti-rotational locking, optionally with radial play, relative to said flap (1).
Abstract:
The present invention is an extremely compact three leaf geared hinge that is adapted to handle heavy loads, tightly fold back onto itself for space conservation, offer extensive freedom of movement in the horizontal plane and provide an extremely smooth operating action with minimal play in torsion as well as in axial or transverse motions. The hinge has three interconnected leaves jointed by hinge pins. The inner and outer leaves each have two fixed gears on their sides that meshingly engage a set of two rotating gears located on the sides of the middle leaf. The inner leaf has a cylindrical leaf and pin arrangement on one end that may be rotatably secured to a rigid member or housing. The free end of the outer leaf may be attached to the load directly or with a device that allows the load to rotate normally about the extended hinge.
Abstract:
A gear mechanism part for a cable-controlled window lifter is provided that includes a gear wheel and a cable drum that can be driven by the gear wheel. The gear wheel and cable drum are disposed on a common axis. The gear wheel and the cable drum are coupled by a positive fit to an outside gearing disposed on an outside circumference projection. In the cable drum, a fitting chamber for cable end fastening is provided. The fitting chamber is disposed inside the outer circumference projection on a cross-sectional plane projected perpendicular to the axis. In this way, a more compact design of the cable drum and transmission of higher driving torque are achieved.
