Abstract:
A device for opening and closing an outwardly opening pivoting wing, comprising: an actuating device including a support, a crank rotatable relative to the support and a control mechanism operated by the crank, and an arm having a toothed portion which cooperates with said control mechanism, wherein the control mechanism cooperates with the toothed portion of the arm for the translational motion of the arm along a rectilinear direction between a locked wing position and an unlocked wing position, and vice versa, a first and a second slider intended to engage a groove of the wing in a movable manner in a rectilinear direction, wherein the first slider is articulated at a distal end of the arm and wherein the second slider is connected to a locking device.
Abstract:
A locking prison door movement for mounting above a prison door adjacent a prison cell for transporting and locking the prison door includes a support frame and a movable carriage mounted to the support frame for reciprocating motion relative to the support frame. A drop bar extends downwardly toward the floor of the prison and is movable between a raised unlocked position and a lowered lock position in which a lower portion of the drop bar is secured adjacent the floor of the prison. An upper lock bar is movable between a first locked position securing the movable carriage in place and a second unlocked position allowing motion of the movable carriage. A cam mechanism is provided for moving the upper lock bar and the drop bar between their locked and unlocked and is operated by the reciprocating motion of the movable carriage such that the reciprocating motion of the movable carriage causes the locking and unlocking of the drop bar and the upper lock bar. The cam bar is coupled to the movable carriage in such a way that for a portion of the motion of the cam bar the cam bar and the movable carriage move together, and for some other portion of the motion of the cam bar, the cam bar continues its motion while the movable carriage remains stationary, and wherein motion of the cam bar while the movable carriage is stationary causes the locking and unlocking of the one or more locks. The upper lock bar is not visible or accessible to a prisoner, but instead is concealed within the cabinet.
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:
An overhead door with improved biasing means and automatic locking means includes two panels which are substantially horizontal when the door is raised and vertically aligned when the door is closed. An expandable hinge at the interface of the door panels allows the lower panel to move vertically when the door is in the lowered position with the upper end of the lower door panel is spaced from the lower end of the upper door panel. Either the lower end of the upper panel is tapered downwardly toward its outer edge, or the upper end of the lower panel is tapered upwardly toward its outer edge so that the outer edges of the panel ends contact first, biasing the interface of the panels outwardly, when the door is raised. The door also includes a latch that is engaged upon lowering the lower panel relative to the upper panel.
Abstract:
A locking device for a sliding door or a swing and sliding door having a door leaf, the lock device comprising a drive train including at least one motor, a drive transmission and a drive spindle. The locking device also comprises a locking transmission and a torque dividing arrangement.
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.
Abstract:
In an operating device for operating body components of a vehicle, it is provided, with a view to obtaining simple automatic operation as well as unrestricted manual operation, that an electromechanical drive unit comprises at least one drivable first stop element and a power transmission unit at least one second stop element which is connected to the body component, the stop elements being able to bear against each other for transmission of an operation power in a direction of power transmission and to be spaced from each other for uncoupling the drive unit from the power transmission unit in the direction of power transmission. There is no need for any electromechanical coupling for uncoupling purposes.
Abstract:
A drive assembly moves a vehicle closure panel from an open to a closed condition. The drive assembly has a housing and a motor mounted on the housing. A drum and gear assembly is rotatably mounted on the housing. The drum and gear assembly has a drum having a helical groove, a gear in driving engagement with the motor, and a spring biasing the drum in a winding direction relative to the gear. The drum and gear have a lost motion connection therebetween. A cable has an end connected to the closure panel and an opposite end connected to the drum about the helical groove in the winding direction. The drum rotates in the winding direction relative to the stationary gear as the closure panel is manually moved from the open to the closed condition with the spring maintaining a cable tension. The drum and gear rotate together in the winding direction upon energizing the motor effecting powered movement of the closure panel to the closed condition. The motor is afterwards energized in an opposite direction counter-rotating the gear relative to the drum back to a start position.
Abstract:
A liftgate actuating assembly is disclosed for moving a liftgate of a motor vehicle between open and closed positions. The liftgate actuating assembly includes a motor that is fixedly secured to the motor vehicle. The motor has an output shaft capable of bi-directional rotation. A drive gear rotates about a drive shaft and is operatively connected to the output shaft to be rotated thereby. A cable drum is rotatably mounted to the drive shaft. The cable drum is coupled to the drive gear and is rotated thereby. The cable drum includes a cable wrapped thereabout between a drum end fixedly secured to the cable drum and a liftgate end fixedly secured to the liftgate. The cable is used to retract the liftgate from the open position to the closed position. A linkage is operatively connected to the drive gear. The linkage is from a retracted position to an extended position such that the linkage forces the liftgate from the closed position to the open position when the linkage moves from the retracted position to the extended position. The linkage includes a slot that provides lost motion within the linkage. This allows the liftgate to be move manually to the closed position without the motor being activated.
Abstract:
A power liftgate assembly is disclosed for moving a liftgate between an open position and a closed position. The liftgate is secured to a motor vehicle having a roof. The power liftgate assembly includes an elongated bracket that is fixedly secured to the roof of the motor vehicle. The elongated bracket extends between first and second ends. A motor is fixedly secured to the elongated bracket. A slide operatively engages the motor. The slide moves along the elongated bracket. An articulated bracket is connected to the slide and moves with the slide. The articulated bracket includes a slot that extends therealong to provide lost motion between the articulated bracket and the slide. An arcuate bracket extends between the articulated bracket and the liftgate for receiving the motion of the articulated bracket and for moving the liftgate in response thereto.
