Abstract: A window vent system and method automatically vents air pressure from a vehicle cabin as the vehicle door is closing. A drive mechanism is mounted to a vehicle window. A sensor senses open and closed positions of the door latch. When the latch is open, a signal is sent from the sensor to a controller to open the window. When the latch is closed, a signal is sent to the controller to close the window. Software prevents closing of the window in the event of a pinch event. The software also stops the drive mechanism if there is an obstruction to opening or closing of the window. Manual override is also provided to selectively open and close the window.

Abstract: A motor vehicle door includes a door handle unit fixed on the inside on the door edge opposite a door hinge. The door handle unit is motorically pivotable between a folded-in and a folded-out position. In the folded-in position when the vehicle door is closed the door handle unit is arranged behind the vehicle door. In the folded-out position, the door handle unit protrudes laterally outwards by surrounding the door edge and is grippable to open the door. A door mover unit is configured to move the vehicle door in a closed state out of a closed position into a stand-by position, in which the door handle unit can be moved from the folded-in position into the folded-out position. A control unit has a signal input which, upon obtaining the opening signal, controls the door mover unit to move into the stand-by position and controls the door handle unit to pivot into the folded-out position.

Abstract: An opening/closing apparatus for a vehicle, which has a door-lock mechanism, is provided. An output of a motor unit is transmitted to a drum having a planetary gear mechanism, and the slide door of the vehicle is driven by an open-side cable and a close-side cable wound around the drum. A closer cable of the door-lock mechanism is coupled to a carrier of the planetary gear mechanism, and coupled to a latch of the door-lock mechanism via a coupling link. The coupling link is constituted as a toggle mechanism so as to regulate the rotation of the latch by the traction force of the closer cable until the latch is rotated toward a full latch direction from an unlatch position. When the regulation of the latch by the toggle mechanism is released, the latch is rotationally driven toward the full latch direction due to the rotation of the carrier.

Abstract: A door closing apparatus has a latch mechanism that holds a door in a half-closed state and a fully-closed state to a vehicle body. An actuator drives the door when the door is in the half-closed state, a sector gear rotates as the actuator is driven. A first close lever performs closing action according to rotation of the sector gear, and a second close lever performs a door closing action according to the closing action to cause the latch mechanism to perform the closing action. A cancel lever is swingably disposed to the first close lever via a first spring. The cancel lever comes in engagement with the sector gear in a normal state, while performing a door opening action against the biasing force of the first spring to cancel the engagement with the sector gear when an opening operation of an operation handle is performed.

Abstract: An unlock mechanism for a rotary door operator of a transit vehicle includes a pivotally disposed unlock member adapted for rotating a lock member into an unlock position and activating a valve for discharging the fluid pressure from the drive cylinder to enable manual opening of the door. A spring is provided for biasing the unlock member to a non-activated position. The unlock member may be activated either with a cable or a lever handle. A lock sensing switch provides a feedback on the lock condition to the transit vehicle control system. Additionally, a guiding bracket is provided for securing the cable in proximity of the unlock member.

Abstract: The door apparatus has a linear motor for applying a thrust to move a door, a lock device for performing a locking operation and an unlocking operation, and a control unit for controlling the linear motor and the lock device. Upon determining that the lock device is still in a locked state after a set time has elapsed from initiation of the unlocking operation, the control unit controls the linear motor to apply a thrust force to the door while again controlling the lock device to perform the unlocking operation. As a result, even when the locking pin and the lock hole are misaligned to such an extent as to interfere with the unlocking operation, the unlocking operation can be performed without an increase in a thrust output by a solenoid of the lock device, the solenoid can be prevented from overheating and the size and weight of the solenoid can be reduced.

Abstract: The invention relates to a motorized locking device for a door intended in particular for a rail vehicle, with at least one leaf.

Abstract: An apparatus for automatically actuating and securing a door has been shown and described. The automatic door system non-destructively retrofits a conventional door to allow actuation of the door. The automatic door system integrates a lock mechanism and a door actuation mechanism. The automatic door system allows hands-free operation and is suitable for use with pets or humans. The automatic door system controls the arc of the door swing and duration that the door remains open based upon the requestor activating the automatic door system. The automatic door system provides additional security over traditional mechanical locks. Further, the automatic door system allows access profiles to be customized to the requestor.

Abstract: The invention provides a door system for a transit vehicle. It has an actuator which provides a rotary motion about an axis of the actuator for moving the door panel between an open position uncovering the aperture and a closed unlocked position covering the aperture. The actuator also provides a linear motion along the axis of the actuator for moving the door panel between the closed unlocked position and a closed locked position. The rotary motion followed by the axial motion is provided by a cylinder having a piston moved by fluid pressure. The piston includes a guide track in its exterior which engages rollers in the cylinder. The guide track has one portion curving around the piston and one portion parallel to the axis. The curving part provides the rotary motion and the straight part provides the axial motion. When the rotary motion is completed the piston encounters a stop on a shaft which supports the door. The actuator then moves the door axially to engage locks.

Abstract: A drive system is provided for moving a lockable vehicle part. The drive system includes a drive element that operates with a change in length. The element is supported at its ends on the vehicle part and on the body. A releasable snap lock is provided by which the vehicle part is locked in one of its end positions. The snap lock is released by a control stroke of the drive element effectively connected with the release mechanism of the snap lock. The control stroke precedes the working stroke to move the vehicle part by connecting one end of the drive element to a release mechanism. In order to reduce the space required in the vehicle for the drive system, a rotary joint is provided as the release mechanism for the control stroke of the drive element.

Abstract: A window operator and hinge structure for a casement window which can be simply factory pre-set for positioning of a window in either egress or wash modes, with switching between modes requiring no additional parts or special tools. The structure has a pivoted handle movable between a closed, inactive position flush with a sill cover and rotatable to an inclined, active position. The handle, in its pivoting movement, operates window locking structure and also controls the action of a brake, with release of the brake by raising of the handle to operative position. Motion-transmitting connections between the handle and linkage structure include the brake as well as the clutch, with the clutch effective to limit the torque that can be applied to the linkage. The handle can be moved to closed, inactive position with the window open so that no handle protrudes and this movement of the handle sets the brake so that a wind cannot move the window.

Abstract: A swinging gate operating mechanism having a crank and links which withdraw and insert the locking bolt as the linkages pass over center, and aligning linkage centers to allow the mechanism to rotate freely with a pair of indexing links to prevent the gate from rebounding out of the latch as the bolt impacts the jam post.

Abstract: A locking mechanism for coach door leaves of the type which are rotated and then driven axially upward by a powered door operating mechanism. Male and female locking bodies at the top of the door leaf shaft move together and apart axially without being radially engaged as the door leaf moves in or out at final closed position. Any external outward pushing force on the door leaf radially engages the locking bodies to prevent door opening.

Abstract: A hydraulically operated tailgate door which is pivotally hinged to move in an arc about the door hinge until the door is substantially vertical in position adjacent the door frame. Means are provided to enable the door to be moved substantially parallel to the door frame during movement from the closed position to a locked position.

Abstract: An apparatus for locking a door leaf comprising a turnable shaft secured to the door by an arm to drive the door in opening and closing movements under the action of a piston-drive which produces slight axial movement of the shaft as the door approaches the closed position. A first locking element is fixed to the door frame and a second locking element is fixed to the door, the locking elements having wedge-shaped noses which interengage and lock the locking elements when the door is closed and the shaft is lifted. The locking element on the door frame includes an axial extension overlapping the nose of the locking element on the door to form an abutment to limit the degree of angular closure of the door. The axial extension can carry a friction-reducing insert to facilitate relative movement between the noses when the door is lifted at the end of the closure movement.

Abstract: A rear door control mechanism for a stack-forming implement having a compressor roof first raises the door vertically to unlatch it and then rotates the door about an elevated and horizontally transverse axis to permit stack unloading. The door control mechanism functions independently of the compression roof and other wagons' mechanical systems and assures positive door unlatching before the opening mechanism attempts to open the door.
