Abstract:
A drive arrangement (10) has first and second wheels (12, 14) and an endless loop member (16). The path of the member (16) is defined in part by a third wheel (18), between the wheels (12, 14). The wheel (18) is movably mounted so that the length can be changed for the path of the member (16) as it passes around the wheel (18), between the wheels (12, -14). Accordingly, the member (16) can be tightened or slackened around the wheels (12, 14), so that the wheels (12, 14) can be coupled to convey drive from one to the other, through the member (16), or disengaged, so that drive is not conveyed.
Abstract:
The invention relates to a retraction device for a movable piece of furniture, having a pulling means windable on a roll, wherein an electric motor is provided for driving the roll, and having a coupling for releasably connecting the movable piece of furniture to the electric drive, having a first coupling part for fastening to the movable piece of furniture and a second coupling part connected to the pulling means, the first coupling part having an opening for at least the partial acceptance of the second coupling part, a locking mechanism being provided by which the first coupling part can be connected to the second coupling part in at least two different positions, the second coupling part being located at different depths in the opening in the two different positions.
Abstract:
A refrigerator and/or freezer with an appliance carcass, can be closed by at least one door, and a powered door operating device for automatically operating the door. The door operating device has drives both automatically opening and closing the door.
Abstract:
A window assembly including a frame having an interior portion with an inner surface, and a sash having an interior portion and an exterior portion. The window assembly includes an operational mode and a wash mode. In the operational mode, the sash is movable from a closed position to a position in which the sash is generally perpendicular with the frame. In the wash mode, the sash is movable to a position where the exterior of the sash faces toward the interior frame.
Abstract:
A drive arrangement for a shaft, such as a shaft for driving a sectional door, roller shutter or the like, is in the form of a module, carried, in use, by the shaft and including a motor, a driven wheel fixed for rotation with the shaft and drivable, in use, by the motor, and clutch means and operable between the motor and the wheel. The module further includes brace means in the form of a limb attachable to a member which is fixed relative to the axis of the shaft, to brace the module against turning as the shaft is driven.
Abstract:
An electrically driven entryway activation system for opening and closing two spaced swinging doors hung on spaced rotating parallel door posts comprises a base plate extending between the door posts. Levers attached to each door post rotate in a plane parallel to the base plate. A low profile actuation system spaced between the levers comprises a center post, a sector gear journaled on the center post for rotation parallel to the base plate, and a low profile gearmotor mounted between the base plate and the sector gear. A low profile emergency manual mechanism is provided for unclutching the output pinion gear of the gearmotor.
Abstract:
A piece of furniture with a movable furniture component, in particular a drawer or door, includes a drive unit and a device for the mechanical transmission of force from the drive unit to the movable furniture component or the body of the furniture. In particular, a pin is arranged on a lever that can be powered by the drive unit, for the ejection and/or insertion of the movable furniture component. The device for the mechanical transmission of force is arranged in a guide track for the transmission of tensile and thrust forces.
Abstract:
A novel electrical floor-hinge device is provided, which contains an electrical motor and a speed reducing element configured on top of a platform element at a side on top of a body member. A vertical input shaft connected to the speed reducing element is joined to a lateral involute shaft via bevel gears. The involute shaft in turn engages a driven gear on a vertical output shaft. The top end of the output shaft is attached to a seat element whose top surface is fixedly joined to a lower inner corner of a door. By the electrical motor's driving the seat element into clockwise or counterclockwise swing, the door is closed or opened automatically. The speed reducing element can be easily replaced to fit doors of different weight.
Abstract:
A system for raising and lowering a sectional overhead door between an open position and a closed position including, a counterbalance system adapted to be connected to the door, an operator motor assembly mounted proximate to the sectional overhead door in the closed position of the sectional overhead door, at least a portion of the operator motor assembly movable between a door operating position and a door locking position, and a locking assembly (370) having an engaged position to hold the motor assembly in the operating position and a disengaged position to release the motor assembly allowing it to move to the door locking position. The system may be provided with a remote light assembly having a switchable light source in sensing communication with the operator motor such that operation of the motor activates the light source. The system is further provided with a handle assembly (515) operatively engaging the motor assembly (40) and counterbalance system (30) to selectively disconnect the motor assembly (40) from the counterbalance system (30), whereby urging of a rotatable handle (516) to a disconnect position (516′) allows the door (D) to be manually freely moveable with the aid of the counterbalance system (30).
Abstract:
An actuating device for a movable component includes a reversible motorized drive for driving the movable component from a normal position into an open position, the movable component being uncouplable from the reversible motorized drive in its open position. The actuating device includes a driving element movably drivable by the reversible motorized drive and engages in a crank recess and extending along the path of motion of the movable component. A length of the crank recess corresponds at least to a path of motion of the driving element between its normal position and its open position or partially open position. After adjustably driving the movable component into its open position, the driving element may be returned by the reversible motorized drive into the normal position.
