Abstract:
An automotive power pivot door is powered by an electric motor through an electromagnetic clutch. A control device of the door has a control unit configured to carry out a routine which comprises de-energizing an electric motor and disengaging the clutch when the door is lifted up to a full-open position; detecting a moved distance by which the door moves down from the full-open position within a first predetermined time (t 1 ) from the time on which the clutch is disengaged; engaging the clutch when the detected moved distance is equal to or greater than a first predetermined distance (L 1 ); disengaging the clutch again when a second predetermined time (t 2 ) passes from the time on which the clutch is engaged; repeating the process for engaging and disengaging the clutch while following the routine; and judging that the holder fails to operate when the frequency of the engaged condition of the clutch indicates a predetermined frequency.
Abstract:
A damped hinge comprising: a first leaf (32) for securing the hinge to a fixed support; a second leaf (35) for securing a moveable closure to the hinge; a barrel (33) secured to the first leaf (32), the barrel (33) including an axial bore (34); a piston (30) mounted for axial movement within the bore (34), the piston (30) including a cam surface (45); an axially extending member (39) constrained to rotate with the second leaf (35), the member (39) including a cam follower (42) arranged to engage the cam surface (45); the cam surface extending axially so that the piston (30) moves axially within the bore as the second leaf is rotated in relation to the first leaf; a hydraulic fluid contained within the bore (34); at least one of the piston (30) and member (39) including a passageway through which the hydraulic fluid may flow as the piston moves within the bore; wherein the passageway includes an adjustable valve (48, 49) to restrict the flow of fluid to damp opening or closing of the hinge.
Abstract:
According to the present invention there is provided a catch device (21) for use in controlling the movement of a closure, the device comprising: first and second magnetic elements (5, 6) spaced apart from each other; and a movable element (9) such as a keeper element, preferably arranged relative to the magnetic elements, the movable element being movable between first and second holding positions wherein in the first holding position the movable element (9) is held by a magnetic force of the first magnetic element (5) and in the second holding position the movable element (9) is held by a magnetic force of the second magnetic element (6); and means (12) for releasing the movable element from one of the holding positions, the released movable element moving to the other holding position, the device being such that the movement of the closure can be controlled in dependence on the position of the movable element.
Abstract:
A hinge assembly generally includes a first frame assembly configured to be coupled to the first body of the portable communications device, and a second frame assembly configured to be coupled to the second body of the portable communications device. The example hinge assembly also generally includes a first drive assembly, and a second drive assembly. A center shaft couples the first drive assembly to the second drive assembly such that the first drive assembly is pivotable about the center shaft relative to the second drive assembly. In addition, the first and second drive assemblies support hinged movement of the first frame assembly relative to the second frame assembly between at least a closed position and an open position.
Abstract:
The present invention provides a simultaneous closing system for fire doors. The system includes a plurality of individual fire door hook units provided on respective fire doors, a plurality of individual wall-embedded locking units embedded in walls to correspond to the individual fire door hook units, a simultaneous release unit, a drive means, and an automatic closing device. The simultaneous release unit is supported by upper and lower portions of the building and rectilinearly moved within a predetermined vertical range, thus simultaneously releasing the individual fire door hook units from the individual wall-embedded locking units. The drive means functions to drive the simultaneous release unit. The automatic closing device is provided on each of the fire doors, and includes an actuating unit having an actuating shaft, a rack, a pinion, and a pair of support walls.
