Abstract

A rope suspension device with at least one rope suspension module that is adapted for suspension of at least one rope from a rotorcraft, the rope suspension module comprising at least one lockable load beam that is rotatable around an axis of rotation between a locked state and an unlocked state and that is adapted for supporting in the locked state at least one rope that is to be suspended from the rope suspension module, the at least one lockable load beam being, upon unlocking in operation, rotatable from the locked state around the axis of rotation into the unlocked state at least on the basis of a load that is applied to the at least one lockable load beam by means of at least one rope that is supported by the at least one lockable load beam.

First claim

What is claimed is:

1. A rope suspension device with at least one rope suspension module that is adapted for suspension of at least one rope from a rotorcraft, the rope suspension module comprising at least one lockable load beam that is rotatable around an axis of rotation between a locked state and an unlocked state and that is adapted for supporting in the locked state at least one rope that is to be suspended from the rope suspension module, the at least one lockable load beam being, upon unlocking in operation, rotatable from the locked state around the axis of rotation into the unlocked state by application of a load to the at least one lockable load beam by means of the at least one rope that is supported by the at least one lockable load beam, wherein:
the at least one lockable load beam is provided with a hinge, the hinge being pivotally mounted to an associated support member;
at least one locking element is provided that is movable between at least a first and a second position, the at least one locking element being adapted for locking the at least one lockable load beam in the first position and for unlocking the at least one lockable load beam in the second position; and
the at least one locking element is translationally movable in a direction that is at least approximately parallel to a longitudinal extension of at least one lockable load beam in locked state.

2. The rope suspension device according to claim 1 , wherein the hinge is pivotally mounted to the associated support member by means of an associated hinge pin, the associated hinge pin defining the axis of rotation.

3. The rope suspension device according to claim 1 , wherein the associated support member is adapted for mounting the rope suspension module to an associated support structure of a rotorcraft.

4. The rope suspension device according to claim 1 wherein the hinge is provided with an associated failsafe element, the associated failsafe element being adapted for allowing a rotation of the at least one lockable load beam from the locked state around the axis of rotation into the unlocked state only if the at least one locking element is moved to the second position.

5. The rope suspension device according to claim 1 wherein the at least one locking element comprises a first inclined edge and that the hinge comprises a second inclined edge, the first inclined edge being adapted for blocking the second inclined edge in the locked state of the at least one lockable load beam.

6. The rope suspension device according to claim 1 wherein the hinge is provided with a bearing, the bearing being adapted for moving along the at least one locking element in operation during a rotation of the at least one lockable load beam around the axis of rotation from the locked state into the unlocked state.

7. The rope suspension device according to claim 1 , wherein the at least one locking element is connected to an actuating member that is activatable for moving in operation the at least one locking element from the first position into the second position.

8. The rope suspension device according to claim 7 , wherein the actuating member comprises at least one elongated bar that is moveably mounted to the associated support member.

9. The rope suspension device according to claim 8 , wherein the at least one elongated bar is translationally movable in its longitudinal direction along the associated support member for moving the at least one locking element from the first position into the second position.

10. The rope suspension device according to claim 8 , wherein the at least one elongated bar is at least approximately arranged in parallel to a longitudinal axis of the at least one lockable load beam in locked state.

11. The rope suspension device according to claim 1 , wherein at least one keeper is provided, the at least one keeper being moveable from a latching position into an unlatching position, wherein in the latching position of the at least one keeper the at least one rope that is supported by the at least one lockable load beam in locked state is secured on the at least one lockable load beam, and wherein in the unlatching position of the at least one keeper an additional rope can be mounted to the at least one lockable load beam in locked state.

12. The rope suspension device according to claim 11 , wherein at least one operable security element is provided for blocking the at least one keeper in the latching position.

13. The rope suspension device according to claim 1 , wherein a dampening element is provided for dampening the at least one lockable load beam upon reaching of the unlocked state after a rotation from the locked state around the axis of rotation into the unlocked state.

14. A rope suspension device with at least one rope suspension module that is adapted for suspension of at least one rope from a rotorcraft, the rope suspension module comprising:
at least one lockable load beam that is rotatable around an axis of rotation between a locked state and an unlocked state and that is adapted for supporting in the locked state at least one rope that is to be suspended from the rope suspension module, the at least one lockable load beam being, upon unlocking in operation, rotatable from the locked state around the axis of rotation into the unlocked state by application of a load to the at least one lockable load beam by means of the at least one rope that is supported by the at least one lockable load beam;
at least one locking element is provided that is moveable between at least a first and a second position, the at least one locking element being adapted for locking the at least one lockable load beam in the first position and for unlocking the at least one lockable load beam in the second position; and
an actuating member connected to the at least one locking element wherein the actuating member is activatable for moving in operation the at least one locking element from the first position into the second position, the actuating member including at least one elongated bar that is moveably mounted to the associated support member, the at least one elongated bar being translationally movable in its longitudinal direction along the associated support member for moving the at least one locking element from the first position into the second position.

15. The rope suspension device according to claim 14 , wherein the at least one lockable load beam is provided with a hinge, the hinge being pivotally mounted to an associated support member.

16. The rope suspension device according to claim 15 , wherein the associated support member is adapted for mounting the rope suspension module to an associated support structure of a rotorcraft.

17. The rope suspension device according to claim 15 wherein the hinge is provided with an associated failsafe element, the associated failsafe element being adapted for allowing a rotation of the at least one lockable load beam from the locked state around the axis of rotation into the unlocked state only if the at least one locking element is moved to the second position.

18. The rope suspension device according to claim 17 wherein the at least one locking element comprises a first inclined edge and that the hinge comprises a second inclined edge, the first inclined edge being adapted for blocking the second inclined edge in the locked state of the at least one lockable load beam.

19. The rope suspension device according to claim 14 , wherein the at least one elongated bar is at least approximately arranged in parallel to a longitudina
