A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.

Disclosed is a panic bar with a door closer, the panic bar having a locking device installed at a front end of a case and a door closer provided at a rear end of the case. The locking device is released upon pushing of the push bar provided in the case. An air cylinder is installed inside the case. A guide member is installed in one side of the air cylinder and a cylinder sealing cap is installed in the other side of the air cylinder. One side of a piston rod having a piston for compressing and expanding air inside the air cylinder passes through the guide member. A spring disposed between the piston and the guide member is installed on the piston rod.

A power latch assembly for a vehicle door of a motor vehicle includes a ratchet configured for movement between striker capture and striker release positions, wherein the ratchet is biased toward the striker release position, and a pawl configured for movement between a ratchet holding position, whereat the pawl maintains the ratchet in the striker capture position, and a ratchet releasing position, whereat the pawl releases the ratchet to the striker release position. A powered actuator is energizable to move the pawl from the ratchet holding position to the ratchet releasing position, wherein a multistage reduction mechanism operably connects an output of the powered actuator to the pawl to provide a first release torque on pawl during normal use and a greater second release torque on pawl during emergency use.

There is disclosed an emergency door positionable in an exit opening of an aircraft. The door has door supports mountable to the lower wall and each having a pivot point. A first pivot axis is defined between the pivot points. A block is mountable to the lower wall and is offset from a center of the lower wall. A door body is mountable within the opening to the door supporting structure and pivotally mountable to the door supports. The door body is pivotable about the first pivot axis from an initial position in which the door body is within the opening, until the door body is disengaged from the door supports. A bottom portion of the door body abuts against the block to define a removal pivot point. The door body is pivotable about the removal pivot point to remove the door body from the exit opening.

A hinge assembly for a hood of a vehicle is provided. The hinge assembly includes a body member and a hood member. The hood member is pivotally coupled with the body member through a pivot pin. The hood member or the body member partially wraps around the pivot pin such that the hood member or the body member defines a notch. The hood member or the body member is adapted to disengage from the pivot pin on application of an impact force on the hood member.

A vehicle door opening apparatus including a door that is electrically openable, an operator operating button and a passenger operating button for a door opening operation, and a BSM for detecting whether a moving object is approaching, in which in a case where the BSM detects that a moving object is approaching, when an opening operation is performed with the operator operating button or the passenger operating button, opening the door is not allowed, and when an emergency opening operation is performed with the operator operating button, opening the door is allowed.

Provided is a swing door operator (110) for moving a door leaf (120) between a first position and a second position. The swing door operator (110) is arranged to operate in a powered and a powerless mode and comprises a permanent magnet DC motor (310). The motor (310) is arranged to move the door leaf (120) at least from the second position to the first position in the powered mode. The swing door operator (110) further comprises a mechanical drive unit (320), arranged to move the door leaf from the first position to the second position in the powerless mode. In the powerless mode, at least one resistive device is electrically connected in parallel with the motor (310) and arranged to limit a current generated by the motor (310) in response to the movement of the door leaf (120) from the first position to the second position by means of the mechanical drive unit (320). A method for controlling the swing door operator is also provided.

An automatic door operator (30) in adapted for use in an entrance system (1) that comprises a swing door member (10) being operable between a closed position (18) which prevents passage, and an open position (19) which admits passage. The automatic door operator (30) has an electric motor (34), an activation sensor (15) configured for manual actuation by a person wishing to pass through the entrance system, and a controller (31) having a normal operating mode and an emergency mode. In the normal operating mode, the controller is responsive to the activation sensor (15) and configured for, when the activation sensor (15) is actuated, controlling the motor (34) to generate torque for causing the door member (10) in the entrance system (1) to move from the closed position (18) to the open position (19), and to stay in the open position (19) during a configured hold open period (43).

A door presenting device for a motor vehicle door element, having an electric drive unit and an actuating means, wherein the actuating means can be adjusted by means of the drive unit and a gear mechanism arranged between the actuating means and the drive unit, with the result that a movement of the door element can be enabled, and further having a locking means. The door element can be maintained in position by means of the locking means and the locking means can be electrically actuated, namely indirectly, preferably manually, actuated.
