Abstract

A latch includes a handle, a hook, a first link, and a second link. The hook is rotatably mounted to the handle at a first rotational axis. The hook includes a hook body. The hook body includes a first lateral portion and a second lateral portion. The first lateral portion is laterally spaced from the second lateral portion. The first link is laterally between the first lateral portion and the second lateral portion. The first link is rotatably mounted to the first lateral portion and the second lateral portion at the first rotational axis. The second link is laterally between the first lateral portion and the second lateral portion. The second link is rotatably mounted to the first link at a second rotational axis. The second link is configured for translation relative to the first lateral portion and the second lateral portion.

First claim

1 . A latch assembly comprising:
a handle; a hook rotatably mounted to the handle at a first rotational axis, the hook including a hook body, the hook body including a first lateral portion and a second lateral portion, the first lateral portion laterally spaced from the second lateral portion; a first link laterally between the first lateral portion and the second lateral portion, the first link rotatably mounted to the first lateral portion and the second lateral portion at the first rotational axis; and a second link laterally between the first lateral portion and the second lateral portion, the second link rotatably mounted to the first link at a second rotational axis, the second link configured for translation relative to the first lateral portion and the second lateral portion.

2 . The latch assembly of claim 1 , wherein:
the first lateral portion includes a first slot; the second lateral portion includes a second slot; and the second link is positioned within the first slot and the second slot.

3 . The latch assembly of claim 2 , wherein:
the first slot extends longitudinally within the first lateral portion; and the second slot extends longitudinally within the second lateral portion.

4 . The latch assembly of claim 2 , wherein the second link includes a cylindrical body, the cylindrical body positioned within the first slot and the second slot.

5 . The latch assembly of claim 4 , wherein the hook is configured for rotation about the cylindrical body.

6 . The latch assembly of claim 1 , wherein the first link is rotatably mounted to the handle at a third rotational axis.

7 . The latch assembly of claim 6 , wherein the handle forms a first handle slot and a second handle slot, the first link rotatably mounted to the handle within the first handle slot and the second handle slot.

8 . The latch assembly of claim 1 , wherein:
the hook body extends from a first longitudinal end to a second longitudinal end; the hook body further includes a hook portion at the first longitudinal end; and the first lateral portion and the second lateral portion extend from the hook portion to the second longitudinal end.

9 . The latch assembly of claim 8 , wherein the first rotational axis is positioned at the second longitudinal end.

10 . The latch assembly of claim 1 , wherein the handle includes a latch release member, the latch release member positionable in a latched position and an unlatched position, the latch release member configured to contact the first lateral portion and the second lateral portion in the latched position.

11 . A latch assembly comprising:
a hook rotatable about a first rotational axis, the hook including a hook body, the hook body including a first lateral portion and a second lateral portion, the first lateral portion laterally spaced from the second lateral portion; a first link laterally between the first lateral portion and the second lateral portion, the first link rotatably mounted to the first lateral portion and the second lateral portion at the first rotational axis; and a second link laterally between the first lateral portion and the second lateral portion, the second link rotatably mounted to the first link at a second rotational axis, the second link including a cylindrical body, the cylindrical body extending laterally through the first lateral portion and the second lateral portion.

12 . The latch assembly of claim 11 , wherein the first lateral portion and the second lateral portion are configured to translate relative to the cylindrical body.

13 . The latch assembly of claim 11 , wherein:
the hook body extends from a first longitudinal end to a second longitudinal end; and the hook body further includes a hook portion at the first longitudinal end, the first lateral portion and the second lateral portion extending from the hook portion to the second longitudinal end.

14 . The latch assembly of claim 13 , wherein the second link is positioned longitudinally between the first link and the hook body.

15 . The latch assembly of claim 13 , wherein the first rotational axis is positioned at the second longitudinal end.

16 . The latch assembly of claim 11 , wherein the hook is configured for rotation about the cylindrical body.

17 . A latch assembly comprising:
a first latch portion including a keeper; and a second latch portion including:
a handle;
a hook rotatably mounted to the handle at a first rotational axis, the hook including a hook body, the hook body including a hook portion, a first lateral portion, and a second lateral portion, the hook portion configured to selectively engage the keeper, the first lateral portion and the second lateral portion extending longitudinally from the hook portion, the first lateral portion laterally spaced from the second lateral portion;
a first link laterally between the first lateral portion and the second lateral portion, the first link rotatably mounted to the first lateral portion and the second lateral portion at the first rotational axis; and
a second link laterally between the first lateral portion and the second lateral portion, the second link rotatably mounted to the first link, the second link further rotatably mounted to the first lateral portion and the second lateral portion.

18 . The latch assembly of claim 17 , further comprising a first cowl door and a second cowl door, the first cowl door including the first latch portion and the second cowl door including the second latch portion.

19 . The latch assembly of claim 17 , wherein the hook body extends from a first longitudinal end to a second longitudinal end, the hook portion at the first longitudinal end, the first lateral portion and the second lateral portion extending from the hook portion to the second longitudinal end.

20 . The latch assembly of claim 19 , wherein the first link and the second link are longitudinally between the hook portion and the second longitudinal end.
