Abstract:
A door assembly, in particular for a helicopter, has a post; a door fitted to the post by a first and second hinge arranged on an outer wall of the post, so as to rotate about a hinge axis to open and close a door opening; and an emergency release device having a release handle, and a stem which extends through the post along a release axis substantially perpendicular to the hinge axis, rotates axially, in response to operation of the release handle, from a first to a second angular position to detach the door from the post, and is fixed at one axial end to the first hinge; the release handle being connected to the stem to rotate together with the stem about its release axis.
Abstract:
A door control system for a farm implement with a storage bin having a discharge opening and a door movable by a drive mechanism between open and dosed positions relative to the discharge opening includes a dual position door control system. The system may include an arm pivotally connected at one end to the storage bin such that the arm is rotatable between at least a first operating position and a second operating position and a controller connected to the arm and to the drive mechanism.

Abstract:
An electric door operator for opening and closing one or a spaced pair of transit vehicle passenger doors for being mounted over an opening for the doors. A rotatable input shaft has an electric motor secured to the input shaft for driving the input shaft, a worm centrally positioned on the motor shaft, and an electric brake mounted to the input shaft at an end opposite of the electric motor. A drum cam lifts a pinion from a worm gear disconnecting the worm gear from an output gear train in an emergency.
Abstract:
A motor vehicle door arrangement with at least one motor vehicle door and a drive for motorized movement of the motor vehicle door from the closed position into the open position and from the open position into the closed position and with a control for triggering the drive, the control being assigned an optionally actuatable mobile part which the user generally carries and which interacts with the control means over a wireless transmission link when the user approaches the motor vehicle, enhanced actuation automatically carrying out opening and/or a closing as triggered by a predetermined process of use and without the necessity of actuating the mobile part. With respect to enhanced actuation, the control means, especially with the vehicle stopped, can be moved into the activated and deactivated states, and can be triggered by the predetermined usage process exclusively when the control means is in the activated state.
Abstract:
In a four-seat coupe, it is inconvenient for a rear-seat occupant to get in/out of the vehicle while a front-seat occupant is seated. In the present invention, the length of each door of the four-seat coupe is set, so that the rear-seat occupant can get off/on the vehicle while the front-seat occupant is seated. The door is provided with detachable first opening/closing mechanisms at its front and rear end portions. The first opening/closing mechanism at the front end portion of the door is adapted to be released when the front-seat occupant gets off/on the vehicle to allow the first opening/closing mechanism at the rear end portion of the door to support the door so that opening/closing motion can be performed. Also, the first opening/closing mechanism at the rear end portion of the door is adapted to be released when the rear-seat occupant gets off/on the vehicle to allow the first opening/closing mechanism at the front end portion of the door to support the door so that opening/closing motion can be performed.
Abstract:
An operating mechanism for an open/close object comprising a driving device for driving and opening the open/close object, a position detecting device for detecting an open position of the open/close object (1), and a fully open position storage device for storing a fully open position of the open/close object, wherein, when the driving device drives and opens the open/close object, the driving device is stopped in a fully open recognition position stored in the fully open position storage device or a position a fixed amount short of the fully open recognition position. When a current position of the open/close object after completion of the opening drive by the driving device is different from the fully open recognition position (#1), the fully open position storage device sets a new fully open recognition position (#2).
Abstract:
A drive arrangement for a motor vehicle door or hatch which can be moved by a motor with a planet gear and a brake device with a brake. The brake device has a brake drive which is separate from the drive which drives the drive shaft and the brake is able to be moved at least from one of two positions into the other of the two positions by the brake drive. The brake can be an arc-shaped clip pivotally supported by a pivot axle with an inner periphery which is matched to an outer periphery of an element of the planet gear. The brake can be combined with the brake drive as an eddy current brake or can be operated by a further gearing or use of a permanent magnet with which an electromagnet is able to interact.
Abstract:
A rear gate opening and closing apparatus includes a gas stay for biasing a rear gate in an opening direction, a motor for actuating to open or close the rear gate, a clutch for connecting or disconnecting the motor with the rear gate, an encoder for detecting the position of the rear gate, an operating switch for operating an opening and closing motion of the rear gate, and a control means for controlling the motor and clutch to automatically open and close the rear gate. The opening and closing speed of the rear gate is controlled based on a detection signal of the encoder.
Abstract:
A power drive mechanism for a power vehicle sliding door system is provided. The power drive mechanism includes a hinge member adapted for coupling to a vehicle sliding door, a guide member adapted for coupling to a vehicle body, a rack member adapted for coupling to a vehicle body, a drive pinion meshingly engaging the rack member, a drive motor producing a drive torque and a gear train coupling the drive motor and the drive pinion for transmitting drive torque therebetween. The hinge member and guide member cooperate to guide the vehicle sliding door in both generally horizontal and generally vertical directions. The gear train and drive pinion are preferably coupled to said hinge member to maintain meshing engagement of said drive pinion along the length of said rack member. The power drive mechanism also preferably includes a drive clutch for interrupting the transmission of drive torque from the drive motor to the drive pinion to permit the vehicle sliding door.
