Abstract:
The present device has a wire drum connected to a sliding door through a wire cable and being rotated by the power of a motor, an electromagnetic brake which applies braking to the wire drum using a solenoid as the driving source, and a switch transistor which sends electricity to the solenoid when being turned on by a Hi signal from the output port of a controller. The interval between the solenoid and the switch transistor is connected through a line where the voltage level is raised when the switch transistor is turned off and the voltage level is lowered when the switch transistor is turned on. The line is connected through a failure detecting circuit to the input port of the controller.
Abstract:
The clutch includes a drive disk, a follower disk and a brake disk. When current flows, the follower disk is connected with the drive disk to transmit a power from a driving unit to a door-opening/closing mechanism. When no current flows, the follower disk is separated from the drive disk to cut off the power transmission from the driving unit to the door-opening/closing mechanism. In a state that the drive disk and the follower disk are separated from each other, the brake disk is connected to the follower disk to brake the door-opening/closing mechanism in the opening direction of the door, and to allow the door-opening/closing mechanism to move in the closing direction of the door.
Abstract:
A control system for a door or gate which is movable between an open position and a closed position by an automated operator, comprising a door travel organizer which divides the door travel into a plurality of segments and each segment into a plurality of sectors; a sensor to sense at each sector, the resistance of the door or gate against opening and closing whilst moving between the open position and the closed position over a predetermined number of open close cycles, and to generate at least one signal representative of that resistance in each segment over the open close cycle, a recorder connected to the sensor to receive each representative signal and to store such a signal; a comparator to compare each signal with a resistance trip point set for each segment and generate a resistance profile for the door or gate over an open close cycle of the door or gate; a calculator to calculate the resistance trip point for the door or gate for each segment based upon the highest resistance encountered in any sector of that segment; and a controller to receive each trip point and set each trip point as a threshold for each segment such that if resistance of the door or gate sensed by the sensor in any sector exceeds that threshold for that interval, the movement of the door or gate is interrupted.
Abstract:
A control method of sliding a vehicle door by a powered sliding device with a clutch mechanism comprises the steps of stopping a motor in a state that a rotation of a wire drum is restricted by an auxiliary brake when the slide door reaches at a desired semi-open position; displacing the clutch mechanism into a second coupled state by the motor while the auxiliary brake is actuated; releasing the restriction by the auxiliary brake when a predetermined time has elapsed.
Abstract:
A device for a braked movement of furniture doors in particular with a horizontal rotation axis comprises two attachment pieces (11, 12, 211, 212, 311, 312, 411, 412) that are movable in opposite directions around a common rotation axis (13, 213, 313, 413) in a free manner in one rotation direction and against a resisting force of a friction joint in the other rotation direction. Between an attachment piece and the friction joint the device comprises a first surface (28, 228, 328, 428) and a second surface (27, 227, 327, 427) facing each other to delimit a space therebetween in which a wedging element (26, 226, 326, 426) is disposed. The extension of the facing surfaces and/or the shape of the wedging element between them are of such a nature that the wedging element tends to fixedly fit between said facing surfaces causing them to rotate integrally with each other when rotation of the two attachment pieces takes place in the direction that must involve a braked movement.
Abstract:
A brake assembly for locking a vertical or horizontal slidable sash window or door within a track of a frame is disclosed. The track has an elongated base and a pair of spaced apart, opposed sidewalls extending perpendicular from the base. Each sidewall has an inner shoulder spaced from and parallel to the base. The assembly has a slider body having a central opening extending from a front face of the body to a rear face of the body. The slider body has a side opening in each side of the slider body and being in communication with the central opening. A pair of brake members are provided wherein one brake member is slidably positioned within a respective one of the side openings. A cam has a rear face and a front face, and is adapted to receive a pivot member mounted on either the sash window or door. The cam is positioned in the central opening and is adapted to be rotatable within the opening by the pivot member. The cam, slider body and brake members include cooperative structure for converting rotary motion of the cam into radial movement of the brake members through the side openings and axial movement of the cam and slider body to lock the brake assembly within the track.
Abstract:
A power operating system for opening and closing a vehicle liftgate has a pair of drive units supported on the vehicle roof and connected to the liftgate for opening and closing the liftgate. Each drive unit includes a bracket that is secured to the vehicle body for supporting several parts including a reversible electric motor, a gear unit and a track. The electric motor drives a segmented drive linkage inside the track via a gear reduction unit and a sprocket. The segmented drive linkage includes an elongated arcuate link arm that slides in an arcuate track portion of the track and a power roller chain that is stored in a storage track portion when the liftgate is closed. The outboard end of the link arm is pivotally connected to the liftgate to open and close the liftgate as the link arm is extended and retracted by the power roller chain.
Abstract:
A sliding door arrangement with at least one door leaf mounted in a door frame includes a drive for moving the at least one door leaf. The at least one door leaf has a lateral closing edge and a running surface at the lateral closing edge. The door frame has a counter-support surface, wherein, in a closed position of the at least one door leaf, the running surface is located essentially immediately below the counter-support surface and the counter-support surface rests on the running surface for preventing lifting of the door leaf.
Abstract:
A hinge for furniture comprises a bowl (11) and a wing (12) interconnected by connecting rods (13, 14) pivotally mounted to enable a movement between a closed position and an open position of the hinge. An automatic closure mechanism (19, 20) urges the hinge towards a closed position when the hinge is brought close to such a closed position. The bowl (11) comprises regions (21) of interference with at least one connecting rod when the hinge is close to the open position, to offer an increased resistance to said movement over a length thereof close to the open position.
Abstract:
A power operating system for opening and closing a vehicle liftgate has a pair of drive units supported on the vehicle frame and connected to the liftgate for opening and closing the liftgate. Each drive unit includes a bracket that is secured to the vehicle body for supporting several parts including a reversible electric motor, a gear train, a rack and a cradle that are mounted on the bracket. The electric motor drives the rack via an the output gear of the gear train that has an axis. The rack slides in the cradle which is pivotally mounted on bracket so that cradle pivots about the axis of the output gear to hold the teeth of the rack in engagement with the teeth of the output gear to accommodate rocking movement of rack as it moves from a retracted position to an extended position. An arcuate track that is fixed to the vehicle body, and an arcuate link slides in the arcuate track. The arcuate link has an inboard end that is pivotally connected to an end of the rack and an outboard end that is pivotally connected to the liftgate.
