A bidirectional door opening structure includes a first door configured to be opened by rotating about a first end of a vehicle that is adjacent to a roof of the vehicle, a second door configured to be opened by rotating about a second end of the vehicle that is adjacent to the roof of the vehicle, the second end being opposite the first end, a drive unit disposed at a portion of the roof between the first door and the second door, and a controller configured to receive a door drive request with respect to the first door or the second door and to apply a driving force to at least one of the first door or the second door, wherein the drive unit comprises a spindle unit, a latching lever, and a rotation lever.

A safety cabinet includes an enclosure having a double-walled construction and a pair of doors to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a sequential door-closing system that sequentially closes the doors of the safety cabinet in a predetermined order.

A domestic refrigeration appliance includes a heat-insulated inner container delimiting a coolable interior for foodstuffs, a refrigeration device cooling the interior, a door leaf articulated by hinges for opening and closing the interior and an opening aid. At least one hinge is self-closing for automatically closing the door leaf up to a first opening angle. The opening aid includes an actuator and a tappet moving back and forth by the actuator between first and second positions. The opening aid enables the door leaf to be closed if the tappet is in the first position, to move the tappet from the first to the second position to push open the closed door leaf using the tappet up to a second opening angle smaller than the first opening angle, and to automatically move the tappet into the first position immediately or with a time delay after reaching the second position.

A closing device includes an actuator mechanism and a hydraulic damper mechanism. The actuator mechanism includes a pushrod urged by a resilient member towards its extended position. The hydraulic damper mechanism includes a piston, a first rack and pinion gearing for converting the translational motion of the pushrod into a rotational motion of a first pinion, a transmission, which includes a second rack and pinion gearing, between the first pinion and the piston for transmitting and converting the rotational motion of the first pinion into a translational motion of the piston, a one-way valve allowing fluid flow from a first side to a second side of the cylinder cavity when opening the hinged member, and a restricted fluid passage between the first and second sides of the cylinder cavity. The transmission provides together with the pinions of the first and second rack and pinion gearings a reduction gearing between the pushrod and the piston so that the piston reciprocates over a smaller distance than the pushrod.

Provided is a sliding door device which can move a support shaft attached to a sliding door along an inclined portion of a rail by using a pull-in device. The rail (6a) is provided with the straight portion (11) for linearly guiding the support shaft attached to the sliding door (2) and the inclined portion (12) which is inclined with respect to the straight portion (11) and obliquely guides the support shaft. The straight portion (11) of the rail (6a) is provided with the pull-in device (15) which can capture a trigger (18) provided on the straight portion (11) of the rail (6a) and linearly move along the straight portion (11) of the rail (6a) when the sliding door (2) is closed. A pull-in force transmission part (20) for moving the support shaft along the inclined portion (12) of the rail (6a) is coupled to the pull-in device (15).

A vertical pivoting gate operator for positioning a gate between an open position and a closed position is provided. The gate operator includes a motor drive assembly including a motor and a linkage assembly mechanically connecting a motor output to the gate such that in response to actuation of the motor, the linkage assembly transmits an opening force to positioning the gate toward the open position, and a closing force, for positioning the gate toward the closed position. A counterbalance assembly including a biasing member is operable to release stored energy against an input link to rotate a gate arm shaft so as to urge the gate toward the open position and to increase stored energy in response to rotation of the gate traveling toward the closed position to act against the gate as it approaches the closed position.

A closure arrangement for closing a fuel inlet compartment of a motor vehicle body, including a guide device fixed to the vehicle, a cover element displaceably guided on the guide device between a closed position in which the fuel inlet compartment is closed and an open position in which the fuel inlet compartment is open. The guided displacement of the cover element between the closed and open positions includes reciprocating movement and longitudinal movements. The closure arrangement has a drive device operatively connected to the cover element and drives same between the closed and open positions. The drive device has a drive rod element acting axially indirectly on the cover element so as to transmit pulling and pushing forces. The cover element is displaceable between the closed and the open positions by an axial drive movement of the drive rod element with reciprocating and longitudinal movement.

A truck is provided that includes a bed section located rear of a cab section. The bed section is bounded on each side by opposing first and second upward-extending sidewalls, respectively. The truck also includes a truck bed cover that sits over the bed section on at least the first and second upward-extending sidewalls, and includes a door portion to create selective accessibility to the bed section of the pickup truck. The door portion is movable with respect to the first and second upward-extending sidewalls between open and closed positons via an automatic bed cover drive assembly that moves the door portion between open and closed positons according to a plurality of velocities within a predetermined variance.

An opening/closing body drive device includes: a motor which opens or closes an opening/closing body; a drive unit which rotates the motor; and a control unit which controls the drive unit. The drive unit includes a first and second integrated circuits having first and second switching elements and third and fourth switching elements which are connected to each other in series with respect to a power source and connection points of which are connected to one and the other terminals of the motor, respectively. The control unit turn-on drives the first and fourth switching elements or the second and third switching elements when driving the motor to be rotated forward or reversely. The control unit turn-on drives any one of the second and third switching elements when braking the motor during the forward rotation of the motor.

An emergency escape apparatus includes a support frame that is configured to be installed on a door or a wall and that defines an exit opening, an escape door that is located at an inner side of the exit opening and configured to open and close the exit opening and that defines an accommodation space, a driving unit located in the accommodation space and configured to rotate relative to the escape door, and an unlocking device that is located in the accommodation space, that is configured to be pushed by the driving unit, and that is configured to release coupling between the escape door and the support frame based on rotation of the driving unit. The driving unit is configured to be controlled by a control unit based on a sensor detecting an event.
