Abstract

An assembly with a hinged door pivotally mounted to a carrier element, and a locking system for locking the hinged door in an open position, wherein the locking system comprises a hinge bracket rigidly attached to the carrier element, the hinge bracket comprising a locking notch; and an open-door locking device comprising a mounting bracket pivotally mounted to the hinge bracket; a housing connected to the mounting bracket and rigidly attached to the hinged door; a sliding block slidable in the housing between a normal position and an actuated position; and a slider slidable in the housing between a blocking position and a releasing position, the slider being in the blocking position and engaging the locking notch of the hinge bracket for blocking the hinged door in the open position when the sliding block is in the normal position.

First claim

What is claimed is:

1 . An assembly with a carrier element, a hinged door that is pivotally mounted to the carrier element and pivotable between a closed position and an open position, and an open-door locking system for locking the hinged door in the open position, wherein the open-door locking system comprises:
a hinge bracket that is rigidly attached to the carrier element, wherein the hinge bracket comprises a locking notch; and an open-door locking device comprising:
a mounting bracket that is pivotally mounted to the hinge bracket;
a housing that is connected to the mounting bracket and rigidly attached to the hinged door;
a sliding block that is accommodated in the housing and slidable in the housing in a first direction between a normal position and an actuated position; and
a slider that is accommodated in the housing and slidable in the housing in a second direction between a blocking position and a releasing position, wherein the slider is coupled to the sliding block such that the slider is in the blocking position and engages the locking notch of the hinge bracket for blocking the hinged door in the open position when the sliding block is in the normal position.

2 . The assembly of claim 1 , wherein the slider comprises a blocking pin that engages the locking notch of the hinge bracket for blocking the hinged door in the open position when the slider is in the blocking position.

3 . The assembly of claim 1 , wherein the slider comprises a sliding member that slides in the sliding block when the sliding block slides in the housing in the first direction between the normal position and the actuated position.

4 . The assembly of claim 3 , wherein the slider is coupled to a transfer rod that is equipped with the sliding member.

5 . The assembly of claim 3 , wherein the sliding block comprises a wedge with a ramp, and wherein the sliding member slides along the ramp in a third direction when the sliding block slides in the housing in the first direction.

6 . The assembly of claim 5 , wherein the third direction is oblique to the first direction and the second direction.

7 . The assembly of claim 1 , wherein the first direction is at least approximately perpendicular to the second direction.

8 . The assembly of claim 1 , wherein the open-door locking device further comprises a slider return spring that biases the slider into the blocking position.

9 . The assembly of claim 1 , wherein the open-door locking device further comprises a sliding block return spring that biases the sliding block into the normal position.

10 . The assembly of claim 1 , wherein the open-door locking system further comprises a remote actuator for remotely actuating the open-door locking device, wherein the remote actuator is located spaced apart from the open-door locking device on the hinged door.

11 . The assembly of claim 10 , wherein the open-door locking system further comprises a cable, in particular a Bowden cable, that connects the remote actuator with the sliding block.

12 . The assembly of claim 11 , wherein the remote actuator comprises a pivotable thumb lever that is attached to the cable and pivotable for pulling the cable to cause sliding of the sliding block in the housing in the first direction between the normal position and the actuated position.

13 . The assembly of claim 1 , wherein the open-door locking device further comprises a push bar that is rigidly attached to the sliding block and operable for manually moving the sliding block in the housing in the first direction between the normal position and the actuated position.

14 . The assembly of claim 1 , wherein the slider is in the releasing position and disengaged from the locking notch of the hinge bracket for releasing the hinged door in the open position when the sliding block is in the actuated position.

15 . An aircraft comprising an assembly according to claim 1 .
