Abstract

A hook body for a latch mechanism is disclosed. In various embodiments, the hook body includes a plurality of longitudinal members on an upper and a lower surface only, each of the plurality of longitudinal members extending in a longitudinal direction along a full length with respect to the hook body, and a hook body load bearing plate connected to the plurality of longitudinal members and being oriented perpendicular to the longitudinal direction, the hook body load bearing plate configured to slidably receive a shaft connected to a hook, the shaft extending in the longitudinal direction with respect to the hook body.

First claim

What is claimed is:

1 . A hook body for a latch mechanism, comprising:
a plurality of longitudinal members, each of the plurality of longitudinal members extending in a longitudinal direction with respect to the hook body, and a hook body load bearing plate connected to the plurality of longitudinal members and being oriented perpendicular to the longitudinal direction, the hook body load bearing plate configured to slidably receive a shaft connected to a hook, the shaft extending in the longitudinal direction with respect to the hook body.

2 . The hook body of claim 1 , wherein the plurality of longitudinal members includes a first upper longitudinal beam, the first upper longitudinal beam connected to a first aft flange.

3 . The hook body of claim 2 , wherein the plurality of longitudinal members includes a second upper longitudinal beam, the second upper longitudinal beam connected to a second aft flange.

4 . The hook body of claim 3 , wherein a forward upper plate is positioned between and connects the first upper longitudinal beam and the second upper longitudinal beam to the hook body load bearing plate.

5 . The hook body of claim 4 , wherein the forward upper plate extends in the longitudinal direction and lies in an upper plane that is orthogonal to the hook body load bearing plate.

6 . The hook body of claim 5 , wherein the plurality of longitudinal members includes a first lower longitudinal beam, the first lower longitudinal beam connected to the first aft flange.

7 . The hook body of claim 6 , wherein the plurality of longitudinal members includes a second lower longitudinal beam, the second lower longitudinal beam connected to the second aft flange.

8 . The hook body of claim 7 , wherein a forward lower plate is positioned between and connects the first lower longitudinal beam and the second lower longitudinal beam to the hook body load bearing plate.

9 . The hook body of claim 8 , wherein the forward lower plate extends in the longitudinal direction and lies in a lower plane that is orthogonal to the hook body load bearing plate.

10 . The hook body of claim 1 , wherein the plurality of longitudinal members includes an upper longitudinal beam and a lower longitudinal beam, the upper longitudinal beam and the lower longitudinal beam connected to an aft flange and defining an axial cutout extending longitudinally between the hook body load bearing plate and the aft flange.

11 . The hook body of claim 10 , wherein a forward upper plate is positioned between and connects the upper longitudinal beam to the hook body load bearing plate and a forward lower plate is positioned between and connects the lower longitudinal beam to the hook body load bearing plate.

12 . The hook body of claim 11 , wherein the axial cutout is configured to receive a pin, and enable the hook body to slide in the longitudinal direction with respect to the pin.

13 . A latch mechanism, comprising:
a hook body, the hook body including a plurality of longitudinal members, each of the plurality of longitudinal members extending in a longitudinal direction with respect to the hook body, a hook body load bearing plate connected to the plurality of longitudinal members and being oriented perpendicular to the longitudinal direction; and
a hook mechanism, the hook mechanism having a hook and a shaft connected to the hook, the shaft extending in the longitudinal direction with respect to the hook body.

14 . The latch mechanism of claim 13 , wherein the plurality of longitudinal members includes an upper longitudinal beam and a lower longitudinal beam, the upper longitudinal beam and the lower longitudinal beam connected to an aft flange.

15 . The latch mechanism of claim 14 , wherein a forward upper plate is positioned between and connects the upper longitudinal beam to the hook body load bearing plate, the forward upper plate extending in the longitudinal direction and disposed in an upper plane that is orthogonal to the hook body load bearing plate and wherein a forward lower plate is positioned between and connects the lower longitudinal beam, the forward lower plate extending in the longitudinal direction and disposed in a lower plane that is orthogonal to the hook body load bearing plate.

16 . The latch mechanism of claim 15 , wherein the upper longitudinal beam and the lower longitudinal beam connected to the aft flange define an axial cutout extending longitudinally between the hook body load bearing plate and the aft flange and wherein the axial cutout is configured to receive a pin and enable the hook body to slide in the longitudinal direction with respect to the pin.

17 . The latch mechanism of claim 13 , wherein the plurality of longitudinal members includes a first upper longitudinal beam and a first lower longitudinal beam, the first upper longitudinal beam and the first lower longitudinal beam connected to a first aft flange and wherein the plurality of longitudinal members includes a second upper longitudinal beam and a second lower longitudinal beam, the second upper longitudinal beam and the second lower longitudinal beam connected to a second aft flange.

18 . The latch mechanism of claim 17 , wherein a forward upper plate is positioned between and connects the first upper longitudinal beam and the second upper longitudinal beam to the hook body load bearing plate, the forward upper plate extending in the longitudinal direction and disposed in an upper plane that is orthogonal to the hook body load bearing plate and wherein a forward lower plate is positioned between and connects the first lower longitudinal beam and the second lower longitudinal beam to the hook body load bearing plate, the forward lower plate extending in the longitudinal direction and disposed in a lower plane that is orthogonal to the hook body load bearing plate.

19 . The latch mechanism of claim 18 , wherein the first upper longitudinal beam and the first lower longitudinal beam connected to the first aft flange define a first axial cutout extending longitudinally between the hook body load bearing plate and the first aft flange and wherein the second upper longitudinal beam and the second lower longitudinal beam connected to the second aft flange define a second axial cutout extending longitudinally between the hook body load bearing plate and the second aft flange.

20 . The latch mechanism of claim 19 , wherein the first axial cutout and the second axial cutout are configured to receive a pin, and enable the hook body to slide in the longitudinal direction with respect to the pin.
