Abstract

Disclosed is an apparatus for maintaining a position of a vehicle door relative to a vehicle frame may include a link and a fastener. The link may have a first end and a second end. The first end may have a loop and the first end may be at an opposite end of the link from the second end. The fastener may be on a surface of the link and may be configured to fasten the link to the vehicle frame. A hook may be on the second end. The loop may be an arc or an incomplete circular portion. The vehicle may be a rotorcraft vehicle.

Claims (34)

1. An apparatus for maintaining a position of a vehicle door relative to a vehicle frame, the apparatus comprising:

a link comprising:

a first end having an arc-shaped loop; and

a second end having a hook, the first end being at an opposite end of the link from the second end; and

a fastener on a surface of the link configured to directly couple the surface of the link to the vehicle frame, wherein the fastener is a magnetic fastener or a hook and pile fastener.

2. The apparatus of claim 1 , wherein the link has a cross section along a longitudinal direction including a width dimension that is no more than twenty percent of a length dimension.

3. The apparatus of claim 2 , wherein the link is configured to withstand, in a longitudinal direction, a tensile force of at least four hundred pounds and a compressive force of at least five hundred pounds.

4. The apparatus of claim 1 , wherein the hook has a longitudinal axis that is perpendicular to a longitudinal axis of the link.

5. The apparatus of claim 1 , wherein the arc-shaped loop is an incomplete circular portion.

6. The apparatus of claim 1 , wherein the fastener is half-way between the first end and the second end.

7. The apparatus of claim 6 , wherein the fastener is a hook and pile fastener.

8. The apparatus of claim 6 , wherein the vehicle frame is a rotorcraft vehicle frame.

9. The apparatus of claim 6 , wherein the fastener is a magnetic fastener.

10. An assembly for maintaining a position of a vehicle door relative to a vehicle frame comprising:

a link having a first end and a second end, the first end having an arc-shaped partial loop, the second end having a hook, and the first end being at an opposite end of the link from the second end;

a first bracket configured to attach to the vehicle door and engage the arc-shaped partial loop at the first end;

a second bracket configured to attach to the vehicle frame and to engage the hook at the second end; and

a fastener on a surface of the link, the fastener configured to the link directly couple the surface of to the vehicle frame, wherein the fastener is a magnetic fastener or a hook and pile fastener.

11. The assembly of claim 10 , wherein the link has a cross section along a longitudinal direction including a width dimension that is no more than twenty percent of a length dimension.

12. The assembly of claim 11 , wherein the link is configured to withstand, in a longitudinal direction, a tensile force of at least four hundred pounds and a compressive force of at least five hundred pounds.

13. The assembly of claim 10 , wherein the vehicle is a rotorcraft.

14. The assembly of claim 10 , wherein the hook is an elongate member having a longitudinal axis that is perpendicular to a longitudinal axis of the link.

15. A rotorcraft comprising:

a door of the rotorcraft;

a frame of the rotorcraft;

an assembly for maintaining a position of the door relative to the frame, the assembly comprising a link having a first end and a second end, the first end having an arc-shaped partial loop, the second end having a hook, and the first end at an opposite end of the link from the second end;

a first bracket attached to the door and configured to engage the partial loop at the first end;

a second bracket attached to the frame and configured to engage the hook at the second end; and

a fastener on a surface of the link, the fastener configured to directly couple the surface of the link to the frame.

16. The rotorcraft of claim 15 , wherein the link has a cross section along a longitudinal direction including a width dimension that is no more than twenty percent of a length dimension.

17. The rotorcraft of claim 16 , wherein the link is configured to withstand, in a longitudinal direction, a tensile force of at least four hundred pounds and a compressive force of at least five hundred pounds.

18. The rotorcraft of claim 15 , wherein the fastener is half-way between the first end and the second end, and the fastener is a hook and pile fastener or a magnetic fastener.

19. The rotorcraft of claim 15 , wherein the fastener is a magnetic fastener.

20. The rotorcraft of claim 15 , wherein the fastener is a hook and pile fastener.
