Abstract

A latch handle is disclosed. The latch handle may comprise a first portion and a second portion. The first portion may comprise a high aspect ratio. The second portion may have a width greater than the second portion.
A nacelle is disclosed. The nacelle may comprise a first panel and a latch assembly. The latch assembly may include a latch housing and a latch handle. The latch handle may include a first portion and a second portion. The first portion may comprise an aspect ratio greater than one. The second portion may have a width greater than the width of the first portion. A cut-out configured to accommodate the latch assembly may be disposed on the first panel. The first panel may be a fan cowl panel.

First claim

We claim:

1. A latch handle comprising:
a first portion and a second portion;
wherein the first portion comprises an aspect ratio greater than 1;
the second portion has a width greater than the first portion;
wherein the latch handle is configured to actuate a latch to couple a first fan cowl to a second fan cowl; and
the second portion pivots away from the second fan cowl in response to the latch handle moving to an open position.

2. The latch handle of claim 1 , wherein a portion of the latch handle includes an aperture extending from an outward surface to an inward surface.

3. The latch handle of claim 1 , further comprising a panel extending perpendicular from an inward surface of the latch handle, wherein an aperture is disposed on the panel.

4. The latch handle of claim 1 , wherein the second portion includes a notification feature configured to be visible when the latch handle is in an open position.

5. The latch handle of claim 1 , wherein the latch handle is a fan cowl latch handle.

6. The latch handle of claim 1 , wherein the second portion is circular.

7. The latch handle of claim 1 , wherein the latch handle is mounted to a latch housing, wherein the latch housing comprises a first half configured to attach to the first fan cowl and a second half configured to attach to the second fan cowl.

8. The latch handle of claim 7 , wherein the latch housing includes a cutout configured to contain at least a portion of the latch handle.

9. A nacelle comprising:
a first panel;
a latch assembly including a latch housing and a latch handle;
wherein the latch handle includes a first portion and a second portion;
wherein an aperture is disposed in the first portion of the latch handle for facilitating opening of the latch handle;
the first portion comprises an aspect ratio greater than one;
the second portion has a width greater than the first portion;
a cut-out is disposed on the first panel;
the cut-out is configured to accommodate the latch assembly; and
the width is measured in a direction of an axis of rotation of the latch handle.

10. The nacelle of claim 9 , wherein the latch housing is configured to contain at least a portion of the latch handle.

11. The latch handle of claim 9 , further comprising a second panel extending perpendicular from the latch handle, wherein a pivoting aperture is disposed on the second panel.

12. The nacelle of claim 11 , wherein the latch handle is configured to pivot about the pivoting aperture.

13. The latch assembly of claim 9 , wherein the second portion includes a notification feature configured to be visible when the latch handle is in the open position.

14. The nacelle of claim 9 , wherein the latch assembly is configured to secure at least a portion of the first panel to the nacelle.

15. The nacelle of claim 14 , wherein the first panel is a fan cowl panel.

16. The nacelle of claim 9 , wherein the second portion is at least twice as wide as the first portion.

17. The nacelle of claim 9 , wherein the first panel comprises a first fan cowl and a second fan cowl, and the latch housing comprises a first half attached to the first fan cowl and a second half attached to the second fan cowl.
