The linkage assembly includes a hinge linkage assembly coupled to the articulated hinge arm and the fuselage fitting and controlling movement of the hinge members relative to each other and relative to the fuselage fitting. The linkage assembly includes a door linkage assembly coupled to the articulated hinge arm and the door to control positioning of the door between open and closed positions.

An articulated hinge assembly for connecting a door to a fuselage of an aircraft includes an articulated hinge arm having a first hinge member pivotably coupled to a second hinge member at an elbow. A fuselage fitting is pivotably coupled to a fuselage bracket and a door fitting is pivotably coupled to a door bracket of the door. The articulated hinge arm is movable from a collapsed position to an expanded position to move the door from a door closed position to a door open position. The articulated hinge assembly includes a linkage assembly coupled to the articulated hinge arm, the fuselage fitting and the door fitting controlling movement of the first hinge member and the second hinge member relative to each other and relative to the fuselage fitting. The linkage assembly controls positioning of the door.

A rear door assembly includes a rear opening and a roof structure having a recessed area. A carrier is movable along a portion of the recessed area between a rearward location to a forward location. A motor is attached to the carrier and the vehicle. The motor is operable to move the carrier relative to the roof structure and the rear opening between the rearward location and the forward location. A rear door has a hinge pivotally supported to the carrier for movement therewith. The rear door is movable between a door closed orientation covering the rear opening, an intermediate orientation partially exposing the rear opening and a door open orientation exposing the rear opening. A linear movement device has a first end attached to the carrier for movement therewith and a second end attached to the rear door at a location spaced apart from the hinge.

A device for assisting the opening and closing of a door in a structure. The device may comprise: a door shaft configured to rotate about a longitudinal axis thereof in both a first direction and in a second opposite direction, and configured to be mounted to the structure to form a hinge about which the door may rotate in the both the first and second directions relative to the structure; a first actuator linked to the door shaft and configured to control a speed of rotation of the door shaft in the first direction; and a second actuator linked to the door shaft and configured to drive rotation of the door shaft in the second direction. The second actuator is an electromechanical actuator.

The present invention relates to a structurally novel eccentric cam action door closer for a glass door. The matching of the first and second rollers on the piston pressing assembly with the eccentric cam on the cam shaft realizes the door closer stably keeps the door in the opened or closed state. When the door is clockwise opened in place, the first roller is embedded in the first opening arc recess, thereby fixed to the eccentric cam. When the door is counterclockwise opened in place, the second roller is embedded in the second opening arc recess, thereby fixed to the eccentric cam. When the door is closed in place, the first and second rollers are embedded in the first and second closing arc recesses, thereby fixed to the eccentric cam. Thus, the cam shaft is stopped from rotating, achieving door angle fixing effect and stopping the door.

A door closer may utilize a door closing device (e.g., spring) and a force adjustment device (e.g., a motor) in order to allow for manual door opening and assisted door closing. During operation, as a door is manually opened, the spring is loaded (e.g., compressed or tensioned) above its pre-loaded closed position state. Once manual opening is completed, the spring that is loaded during opening begins returning to the pre-loaded closed position state, and thus, moves the door automatically towards the closed position. Depending on the pre-loaded spring setting, the closing force of the door may not be enough to close the door, or to close the door with the preferred force. As such, during closing a controller may engage a motor not to drive the door directly, but to increase the pre-load of spring to increase the closing force in order to allow the door to close as preferred.

The present disclosure generally relates to a lockable device, and more particular to a biometric fingerprint safe having a top opening wall which is released to upwardly fold at its opened position after verifying a fingerprint of a user. The biometric fingerprint safe includes a supporting mechanism provided between the housing and the lid for applying an upward force against the lid, a fingerprint module, a bolt matched with a latching mechanism installed in the housing, the latching mechanism has a motor electrically connected to the fingerprint module, a driving locking plate driven by an eccentric rod connected with the motor, a driven locking plate which is arranged side by side with the driving locking plate and synchronously actuated by the driving locking plate to rotate, so that the driven locking plate being matched with the bolt for locking or releasing the lid.

A pneumatic release system has an inlet arranged to be connected, in use, to a supply of pressurised fluid, and an outlet arranged, to be connected, in use, to an end device. The system defines therethrough, a flow path for fluid from the inlet to the outlet. The system includes a piston mounted in and axially moveable relative to a cylinder, the inlet and outlet defined in the cylinder. The piston has a piston end on which are mounted upper and lower seals and is biased to a first closed position, in which the upper and lower seals define a chamber within the cylinder to retain pressurised fluid from the inlet, the upper seals preventing flow of the fluid from the chamber to the outlet, and wherein an external force applied to the piston moves the upper seals away from sealing engagement with the cylinder.

A drive for adjusting an adjustment element of a motor vehicle, the drive including a hollow cylinder, a rod guided axially therein, two articulated parts configured to provide linear drive movements to the motor vehicle and form a drive connection to the adjustment element and the rest of the motor vehicle. The one articulated part axially fixed to a first component of the components of the drive unit and the other articulated part axially fixed to a second component of the components of the drive unit in the installed state. The drive has a drive spring assembly including a drive spring acting on the articulated parts. In the installed state, at least one of the components of the drive unit is axially fixed to a securing element by a threaded connection, and the securing element projects radially into an axial projection of a spring material of the drive spring assembly.
