Abstract:
A floodgate winch is provided to ascend and descend a floodgate manually or automatically without installing a friction clutch, to keep a floodgate locked automatically by preventing a floodgate from descending using a manual operation unit, and to stop a floodgate from stopping by using an emergency cut-off valve. A floodgate winch comprises frames(100) installed at two sides of a floodgate, a manual operation unit(200) coupled with a first worm(212) rotated by a rotary handle(210) installed to the frame and a first planetary gear(220) supplied with power from a first worm wheel(214) engaged with the first worm, an automatic operation unit(300) installed to the upper part of the frame, provided with a driving motor generating power, a second worm(340) operated by the driving motor and a second planetary gear(350) supplied with power from a second worm wheel(341) engaged with the second worm, supplied with power by a driving sprocket(355) and a driven sprocket(356) connected to the second planetary gear and coupled with the first planetary gear, and a power transmission unit transferring power for reciprocating a floodgate vertically by the manual operation unit or the automatic operation unit. In addition, an overload prevention device is installed to the second worm shaft to prevent the driving motor from being damaged by overload, and an emergency stopping device(330) is installed to the automatic operation unit and provided with an emergency cut-off valve(332) to cut off a floodgate urgently.

PURPOSE: An automatic open a shut apparatus for a gate door is provided to open and shut a gate door without noise and strengthen the durability by a driving shaft and a transfer pipe. CONSTITUTION: In an automatic open and shut apparatus for a gate door, a motor(30) is driven by the signal of a sensor(20) that is installed at the upper part of door frame of gate door, and rotates a shaft of motor in right direction. And at the same time a driving shaft(40) which interlocks with the shaft of motor rotates in right direction. A transfer pipe(50) has a right helical gear groove part in the inside surface to be united with a right helical gear part(41) of the driving shaft. And a door fixing bracket(60) is slid into the opened end transfer pipe.
Abstract:
Disclosed is an actuator for the rotary drive of a vehicle flap. The actuator includes an electric motor, which has a output shaft with a center axis, an output unit, which is in force-transmitting connection with the electric motor in such a manner that activation of the electric motor causes a rotational displacement of the output unit about an axis of rotation of the output unit, and a mounting unit which is configured to support the actuator in force-transmitting connection with a superordinate assembly relative to the drive unit such that, upon activation of the electric motor, a displacement of the drive unit relative to the mounting unit takes place. Also disclosed is a storage apparatus for a vehicle door and a motor vehicle.
Abstract:
A brake arrangement for a drive apparatus includes a brake case (15), a first brake element (17), a second brake element (19), and a preload (21) for preloading one of first brake element (17) and second brake element (19) onto the other of first brake element (17) and second brake element (19). A brake arrangement for a drive apparatus, which brake arrangement exhibits a substantially temperature-dependent and consistent braking action, is realized in that an intermediate element (20) is arranged between the first brake element (17) and the second brake element (19), and the first brake element (17) and the second brake element (19) are spaced apart from one another by the intermediate element (20).
Abstract:
A vertical door latch assembly includes a housing and a bolt movably attached to the housing having a catch portion. A drive motor is located within the housing and is configured to selectively move a lock assembly between a locked position preventing movement of the bolt and an unlocked position allowing movement of the bolt. A controller is in electrical communication with the drive motor and is configured to direct the actuator lock assembly between the locked position and the unlocked position.
Abstract:
A panel is supported by a track for movement along the track between a closed position and an open position, and is further supported by a pivot assembly that is configured to pivot the track and the panel with respect to a body portion.
Abstract:
A vehicle door checker integrated with a power drive unit for an automobile door includes a direct current permanent magnet electric motor subject to cogging torque. The electric motor includes a central shaft. The vehicle door checker also includes a cogging torque increase device that is mounted to the central shaft externally of the motor. The cogging torque increase device includes pairs of oppositely magnetized permanent magnets that are mounted coaxially in a stator and rotor respectively about the motor shaft. The stator magnets and the rotor magnets shift into and out of alignment with each other as the shaft is rotated such that the motor is held in multiple discrete stable positions that correspond to check positions of an automobile door.
Abstract:
A mechanism (A) that is used in moveable facades and shutter systems, garage doors and access systems is provided, allowing opening and closing of panels (P) positioned between rail profile (10) and lower rail (R).
Abstract:
A panel device (10), particularly a roof light for a recreational vehicle, comprises an at least substantially polygonal frame (11, 12) which surrounds an opening (15). A window (20) is connected to the frame for pivoting about a pivot axis and comprises a panel (21) which extends over the opening. Provided between the frame and the window is a stay device (50) which is manipulable between a first position, in which the window is forced into a flat state and closes the opening, and at least one second position in which the window is raised by the stay device and leaves the opening at least partially clear. The stay device comprises a stay (51, 52) which extends movably from an elongate guide (61, 62) at a first outer end and is connected pivotally to the window at an opposite, second outer end. The stay (51, 52) is adjustable in the guide and is coupled to an actuator (78) via a flexible transmission (71 . . . 83). The transmission comprises at least one tension-resistant pull member (71-73) which is coupled to the stay (51, 52) and which is movable in an axially at least substantially rigid yet flexible sleeve (81-83), a first outer end of which is fixed to or close to the stay (51, 52) and a second outer end of which is attached to or close to the actuator (78).
