A door opening and closing apparatus includes a rail module including: a rail member extending along a front-and-rear direction; a drive device mounted on the rail member; and a supporting member coupled to one end portion of a closing cable the other end portion of which is connected to the drive device and one end portion of an opening cable the other end portion of which is connected to the drive device. The rail module is provided with the drive device fastened to an outside of a vehicle body such that a part of the drive device goes inside the vehicle body through an opening provided on the vehicle body. A portion of a housing of the drive device located outside the vehicle body closes the opening while a sealing member is interposed therein.

A vehicle opening and closing body control device includes an opening and closing drive device and a controller. When the opening and closing body is being closed, in a case where the position of the opening and closing body when a trapping of a foreign object is detected is outside a specified range between a fully closed position and a specified position, the controller controls the operation of the opening and closing drive device to reverse the opening and closing body to perform the opening operation by a predetermined opening-and-returning distance and then stop the opening and closing body. In a case where the position of trapping is in the specified range, the controller reverses the opening and closing body to perform the opening operation by the predetermined opening-and-returning distance or a greater distance and then stop the opening and closing body outside the specified range.

A sliding door device for a vehicle may include a sliding door opening/closing a door opening formed in a vehicle body, a door rail mounted on the sliding door, a vehicle body rail mounted on the vehicle body, a central support structure for movably supporting the sliding door, a hook releasably locking the central support structure to the door rail, and a lower support structure for movably supporting a lower portion of the sliding door. The central support structure includes a central slider. The lower support structure includes a lower slider, a gear device, a link mechanism, a chain, and a chain tensioner.

A vehicle door structure 1 includes a lock mechanism 40. The lock mechanism 40 includes a portion to be locked 50 provided to a guided body 18, a first locking portion 60 arranged at a position that corresponds to the portion to be locked 50 when the slide door 6 is in the fully closed position, and a second locking portion 70 arranged at a position that corresponds to the portion to be locked 50 when the slide door 6 is in the fully open position. The portion to be locked 50, in the fully closed position or the fully open position, protrudes toward the first locking portion 60 or the second locking portion 70 and is locked by the first locking portion 60 or the second locking portion 70. The second locking portion 70 protrudes toward the portion to be locked 50 when the swing door 70 is opened.

A system and portable device are provided for opening and closing sliding doors associated with conventional sliding doors as used in residences and businesses. The portable sliding door device attaches to a sliding door via a bracket, and moves along the same track used by the sliding door. The sliding door device can be initiated to move the sliding door to the open position through remote control, voice-activation, and proximity transmitters. The sliding door device can communicate with wireless routers and be remotely controlled and monitored by computers, netbooks and cell phones. The sliding door device has safety features, including cameras and speakers to ward off attempted break-ins.

A drive apparatus for an adjusting device for adjusting a vehicle part, in particular a window lifter, comprising a carrier element, a transmission element which can be driven by means of a motor unit, and a drive housing which is arranged on the carrier element and which has a bearing element for rotatably bearing the transmission element about an axis of rotation. The carrier element has at least one first positive-locking element and the drive housing has at least one second positive-locking element, which are in engagement with one another for a rotation-preventing securing action, wherein an elastic dampening element is arranged between the at least one first positive-locking element and the at least one second positive-locking.

A vehicle side door opening/closing device includes a motor, a gear case to which the motor is fixed and which is fixed to a side door, a speed reducer built in the gear case, an output gear provided to the speed reducer, a rack of which an end portion is pivotably supported to a vehicle body and which is provided with a rack gear, and an engagement holding unit connected with the gear case and movably supporting the rack while constantly keeping an engagement allowance between the rack and the output gear. The side door is moved in an opening direction by pushing the rack and in a closing direction by pulling the rack respectively following the rotation of the output gear. The engagement holding unit rotates around a rotation center of the output gear by a swing of the rack following the opening/closing operation of the side door.

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 closed positions relative to the discharge opening includes a dual position door control system. The system includes at least two controllers at spaced positions relative to the door and coupled to a drive mechanism for opening and closing the door.

A sensor unit includes a garage door sensor, a frame configured to be secured at one side of an opening for a garage door, and a cover. The garage door sensor is connected to said frame. The cover is configured to accommodate at least a portion of said garage door sensor. The cover is removably secured to said garage door sensor, such as for periodic cleaning.

A door operator and a method for moving a door leaf between a closed and open position utilize a drive unit, a control unit, and a supervise unit. The drive unit is connected to and moves the door leaf between the open and closed position. The control unit is connected to and controls the movement of the drive unit. The supervise unit includes a status management unit and one or more sensors that provide sensor data associated with an operation of the door leaf. The status management unit receives the sensor data from the one or more sensors, determines a status pattern from a plurality of status patterns of the operation of the door leaf at least based on the sensor data, with a first status pattern being associated with a status event, and triggers the status event in response to the first status pattern.
