Abstract

Embodiments of the invention are directed to a soft shelter extension for use with a hard shelter where the hard shelter has a perimeter opening defined by a side wall and sealable by a deck rotationally coupled thereto, wherein the deck is prevented from over rotating by a pair of opposing cables linking the side wall to the deck. Such embodiments include a bow assembly having a plurality of bows wherein first ends are linkable to each other and second ends are linkable to each other, either directly or indirectly. These embodiments further include a pair of cable slide interfaces linked to respective first and second ends of the plurality of bows to receive the respective pair of cables. A flexible panel covers the bow assembly, and mates to the side wall and to the deck to form an enclosed space when the deck is rotated to a position wherein the cables are in tension.

Claims

1. A soft shelter extension for use with a hard shelter having a perimeter formed by a side wall and defining an opening sealable by a deck rotationally linked thereto, wherein the deck is prevented from over rotating by first and second cables linking the side wall to the deck, the extension comprising:

a bow assembly having a plurality of bows, each bow including a first end and a second end, wherein the first ends are linkable to each other, either directly or indirectly, and the second ends are linkable to each other, either directly or indirectly;

first and second cable slide interfaces linked to respective first and second ends of at least one of the plurality of bows to receive the respective pair of cables; and

a flexible panel to cover the bow assembly, and matable to the side wall and to the deck to form an enclosed space when the deck is rotated to a deployed position.

2. The soft shelter extension of claim 1 wherein the bow assembly is supported by the first and second cables during deployment of the extension.

3. The soft shelter extension of claim 1 further comprising first and second struts linkable at first ends to respective first and second ends of the plurality of bows, and linkable at second ends to the deck.

4. The soft shelter extension of claim 3 wherein the first and second struts comprise a macro extension feature at one end thereof to selectively increase the struts'"'"' effective length upon deployment of the extension and to resist unintentional retraction of the struts when so extended.

5. The soft shelter extension of claim 4 wherein the macro extension feature comprises a lever having a first end, a second end, and a body portion, and wherein the first end of each lever is attachable to at least one of the plurality of bows, the body portion is linkable to one end of a strut and the second end operates as a lever arm.

6. The soft shelter extension of claim 3 wherein each strut detachably connects to one end of the bow assembly.

7. The soft shelter extension of claim 6, wherein each strut is disconnected from one end of the bow assembly during stowage of the extension.

8. The soft shelter extension of claim 3 wherein each strut comprises a micro length adjustment feature that modifies the static length of the strut.

9. The soft shelter extension of claim 8 wherein the micro length adjustment feature comprises a screw jack length adjustment arrangement.

10. The soft shelter extension of claim 1 wherein at least some of the bows are secured to the flexible panel.

11. A hard shelter with a soft shelter extension combination comprising:

a perimeter formed by a side wall of the hard shelter and defining an opening

a deck rotationally linked to the side wall;

first and second cables linking the side wall to the deck to prevent over-rotation of the deck relative to the side wall during deployment of the soft shelter;

a bow assembly having a plurality of bows, each bow including a first end and a second end, wherein the first ends are linkable to each other, either directly or indirectly, and the second ends are linkable to each other, either directly or indirectly;

first and second cable slide interfaces linked to respective first and second ends of at least one of the plurality of bows to receive the respective pair of cables; and

a flexible panel to cover the bow assembly, and matable to the side wall and to the deck to form a soft shelter enclosed space when the deck is rotated to a deployed position.

12. The combination of claim 11 wherein the bow assembly is supported by the first and second cables during deployment of the extension.

13. The combination of claim 11 further comprising first and second struts linkable at first ends to respective first and second ends of the plurality of bows, and linkable at second ends to the deck.

14. The combination of claim 13 wherein the first and second struts comprise a macro extension feature at one end thereof to selectively increase the struts'"'"' effective length upon deployment of the extension and to resist unintentional retraction of the struts when so extended.

15. The combination of claim 14 wherein the macro extension feature comprises a lever having a first end, a second end, and a body portion, and wherein the first end of each lever is attachable to at least one of the plurality of bows, the body portion is linkable to one end of a strut and the second end operates as a lever arm.

16. The combination of claim 13 wherein each strut detachably connects to one end of the bow assembly.

17. The combination of claim 16, wherein each strut is disconnected from one end of the bow assembly during stowage of the extension.

18. The combination of claim 13 wherein each strut comprises a micro length adjustment feature that modifies the static length of the strut.

19. The combination of claim 18 wherein the micro length adjustment feature comprises a screw jack length adjustment arrangement.

20. The combination of claim 11 wherein at least some of the bows are secured to the flexible panel.
