Abstract:
PURPOSE: A foldable door structure is provided to simplify a machining process by coupling multiple first and second frames to each other without dome-shaped frames. CONSTITUTION: A foldable door structure comprises a fixed frame(10), multiple first frames(20), second frames(30), wheels(40), and a housing(50). The fixed frame has a pair of vertical bars. The first and second frames are coupled to the fixed frame and cross each other in an X-shape. The wheels are formed on the bottom ends of the second frames. The housing receives the folded first and second frames therein.
Abstract:
A hinge device driven by an electric motor is provided to suitably perform two types of opening/closing operations including a manual opening/closing by means of a lead portion and electric opening/closing. The first rotation member(20) is rotatably attached at an output shaft(18) interworking with a gear mechanism and coupled with a lid. The second rotation member(21) is rotatably attached at the output shaft(18) and coupled with the first rotation member(20) through an engagement portion of the first concavo-convex part. The third rotation member(22) is integrally rotated together with the output shaft(18) and coupled with the second rotation member(21) through an engagement portion of the second concavo-convex part. A biasing means(30) is positioned between the first engagement portion(25) provided at the second rotation member(21) and the second engagement portion(26) provided at the second rotation member(21), and presses the first engagement portion(25) toward the first rotation member(20) and the second engagement portion(26) toward the third rotation member(22). A locking unit(40) locks the second rotation member(21) while a motor is suspended.
Abstract:
An image reading apparatus includes a reading unit, a hinge connected to the reading unit, and a cover connected to the hinge. The image reading apparatus further includes a decelerator configured to apply a damping resistance to a particular gear of the hinge, as a planet gear engages with the particular gear during movement of the cover from an open position to a closed position.
Abstract:
A device for opening and closing a movable furniture part such as a drawer, door or shutter, includes a push-out unit having at least one push-out element and a rechargeable energy storage element connected to the push-out element via a coupler, such that when the movable furniture part is pushed a specified or definable distance into the energy storage element, stored energy can be made available as kinetic energy in order to eject the movable furniture part. The coupler comprises a lever system with a plurality of levers connected to each other in an articulated manner via levers.
Abstract:
A device for moving a movable furniture part, including a force accumulator such that by way of the fitted device the furniture part under action of the force accumulator is capable of being put in the opening direction of the furniture part, wherein in a tensioned position of the force accumulator the force accumulator is charged for the opening movement of the furniture part. The device has a locking assembly having a displaceable locking member for locking the tensioned position of the force accumulator, wherein the locking member in the tensioned position assumes a locking position which is unlockable. The locking member in the case of an unlocking procedure is movable from the locking position in a releasing direction, wherein a transmission installation by way of which a movement of the locking member is transmittable to a functional unit which is spaced apart from the locking member is provided.
Abstract:
An opening/closing body control device for a vehicle is provided with a drive section configured to drive an opening/closing body of a vehicle, and a controller configured to control the drive section. In response to detection of an external force input intended to accelerate the opening/closing body in operation, the controller controls the drive section to increase the operating speed of the opening/closing element. The drive section determines that the external force intended to accelerate the opening/closing body has been input if, as one example, the acceleration of the opening/closing body in an operation direction reaches a predetermined value or higher.
Abstract:
A tailgate of a motor vehicle has an opening apparatus configured to avoid overshooting during opening of the tailgate. The opening apparatus is connected to a silicone damper to bring about a damping action in the opening direction and a freewheeling action in the closing direction. Additionally, the opening apparatus is configured so that closing of the tailgate and lock actuation are not impeded.
Abstract:
A clutch switching device for electric rolling doors contains: a housing, a rotating plate, and a shifting bar. The rotating plate is provided in the housing for connecting with the clutch pulling cord. The shifting bar is coupled with the rotating plate and is pulled to drive the rotating plate to move toward a manual mode position or an automatic mode position. The rotating plate has a wrenching portion for matching with a wrench tool so as to wrench the rotating plate. The housing includes a movable fixing element, the rotating plate has a first positioning aperture and a second positioning aperture, such that when the rotating plate is located at a manual mode position, the first positioning aperture aligns and retains with the movable fixing element; when the rotating plate is located at the automatic mode position, the second positioning aperture aligns and retains with the movable fixing element.
Abstract:
A drive device for embarkation and disembarkation devices of public transportation vehicles includes a drive unit arranged within and for driving a rotary column. The drive unit rotates the rotary column about the rotary column longitudinal axis Z-Z during opening and closing processes of the embarkation and disembarkation devices. The drive device is supported on the vehicle. The drive unit includes a drive motor, a non-self-locking reduction gear, and a controllable blocking component with which a rotation of the rotary column can be blocked. The drive device further includes a sensor for detecting the magnitude of an external force, wherein the force acts on the drive device. The drive device further includes an element for analyzing signals of the sensor and for triggering the blocking effect of the blocking component when an external force measured by the sensor exceeds a threshold.
Abstract:
The invention relates to a clutch assembly (8) for providing selective engagement with a rotatable shaft, in particular for selecting between manual and powered driving of an output drive such as a door, shutter or gate. The clutch assembly (8) comprises a stop (16) arranged to rotate with the shaft (18), a cam (20) arranged to move relative to the shaft (18), and a follower (24) arranged to rotate around the shaft (18) and axially movable along the shaft in and out of engagement with the stop (16). The follower (24) is operatively associated with the cam (20) so that movement of the follower relative to the cam brings the follower into engagement with the stop (16) by axial movement, so causing rotation of the shaft (18).
