Abstract

A stowable cargo guide may be configured to couple to a roller tray. The stowable cargo guide may comprise a guide block configured to rotate between a stowed position and a raised position. In the stowed position, the guide block may be located below a conveyance plane of the roller tray. In the raised position, the guide block may be located above the conveyance plane of the roller tray.

First claim

The invention claimed is:

1. A stowable cargo guide, comprising:
a housing;
a guide block located in a block opening defined by the housing and configured to rotate relative to the housing;
a first vertical restraint located in a first restraint opening defined by the guide block and configured to rotate relative to the guide block;
a securement clip located in a clip opening defined by the guide block and configured to rotate relative to the guide block; and
a tray base including a laterally extending protrusion configured to engage a hook end of the securement clip.

2. The stowable cargo guide of claim 1 , wherein the securement clip is biased in a first circumferential direction and the first vertical restraint is biased in a second circumferential direction opposite the first circumferential direction.

3. The stowable cargo guide of claim 2 , wherein the guide block is biased in the second circumferential direction, and wherein engagement between the hook end of the securement clip and the laterally extending protrusion of the tray base restricts rotation of the guide block in the second circumferential direction.

4. The stowable cargo guide of claim 1 , further comprising a first restraint latch located in a first latch channel defined by the guide block and biased toward the first restraint opening.

5. The stowable cargo guide of claim 4 , further comprising:
a second vertical restraint located in a second restraint opening defined by the guide block and configured to rotate relative to the guide block; and
a second restraint latch located in a second latch channel defined by the guide block and biased toward the second restraint opening.

6. The stowable cargo guide of claim 5 , wherein the securement clip is located between the first restraint opening and the second restraint opening.

7. A cargo handling system, comprising:
a roller tray including a first rail, a second rail, and a roller located between the first rail and the second rail; and
a stowable cargo guide coupled to the roller tray, the stowable cargo guide comprising:
a tray base located between the first rail and the second rail;
a housing coupled to the second rail;
a guide block located in a block opening defined by the housing and configured to rotate relative to the housing;
a vertical restraint located in a restraint opening defined by the guide block and configured to rotate relative to the guide block; and
a securement clip located in a clip opening defined by the guide block and configured to rotate relative to the guide block, wherein the tray base includes a laterally extending protrusion configured to engage a hook end of the securement clip.

8. The cargo handling system of claim 7 , wherein the guide block is configured to rotate between a stowed position and a raised position, and wherein in the stowed position the guide block is located below a conveyance plane of the roller, and wherein in the raised position the guide block is located above the conveyance plane of the roller.

9. The cargo handling system of claim 8 , wherein in the raised position a guide face of the guide block vertically overlaps a volume defined by the first rail and the second rail of the roller tray.

10. The cargo handling system of claim 7 , wherein the securement clip is biased in a first circumferential direction and the guide block is biased in a second circumferential direction opposite the first circumferential direction.

11. The cargo handling system of claim 10 , wherein the vertical restraint is biased in the second circumferential direction.

12. The cargo handling system of claim 11 , wherein the stowable cargo guide further comprises a restraint latch located in a latch channel defined by the guide block, and wherein the restraint latch is biased toward the restraint opening.

13. The cargo handling system of claim 8 , wherein the stowable cargo guide further comprises a shaft located through the guide block and the housing, and wherein in the stowed position the shaft is located laterally between the second rail and a guide face of the guide block.

14. The cargo handling system of claim 13 , wherein the guide block comprises a slanted surface extending from the guide face of the guide block, and wherein the slanted surface and the guide face form an angle greater than 90°.

15. A stowable cargo guide, comprising:
a housing;
a guide block located in a block opening defined by the housing and configured to rotate relative to the housing;
a first vertical restraint located in a first restraint opening defined by the guide block and configured to rotate relative to the guide block;
a securement clip located in a clip opening defined by the guide block and configured to rotate relative to the guide block; and
a first restraint latch located in a first latch channel defined by the guide block and biased toward the first restraint opening.

16. The stowable cargo guide of claim 15 , further comprising:
a second vertical restraint located in a second restraint opening defined by the guide block and configured to rotate relative to the guide block; and
a second restraint latch located in a second latch channel defined by the guide block and biased toward the second restraint opening.

17. The stowable cargo guide of claim 16 , wherein the securement clip is located between the first restraint opening and the second restraint opening.

18. The stowable cargo guide of claim 15 , wherein the securement clip is biased in a first circumferential direction and the first vertical restraint is biased in a second circumferential direction opposite the first circumferential direction.
