Abstract

Disclosed is a packing system for a slide of an aircraft evacuation system, the packing system having: a rigid packboard having a first side end and a second side end that opposes the first side end; a first valise flap having a first outer end and a first inner end, the first outer end connected to the first side end of the rigid packboard; a second valise flap having a second outer end and a second inner end, the second outer end connected to the second side end of the rigid packboard; and lacing for tying together the first inner end of the first valise flap and the second inner end of the second valise flap, wherein the first valise flap and the second valise flap are formed of a heat shrink material.

First claim

What is claimed is:

1. A packing system for a slide of an aircraft evacuation system, the packing system comprising:
a rigid packboard having a first side end and a second side end that opposes the first side end;
a first valise flap having a first outer end and a first inner end, the first outer end connected to the first side end of the rigid packboard;
a second valise flap having a second outer end and a second inner end, the second outer end connected to the second side end of the rigid packboard; and
lacing for tying together the first inner end of the first valise flap and the second inner end of the second valise flap,
wherein the first valise flap and the second valise flap are formed of a heat shrink material.

2. The packing system of claim 1 , wherein the first valise flap and the second valise flap are formed of a same heat shrink material.

3. The packing system of claim 2 , wherein the lacing is formed of a heat shrink material.

4. The packing system of claim 3 , wherein the heat shrink material of the valise flaps differs from the heat shrink material of the lacing.

5. The packing system of claim 4 , wherein the valise flaps and the lacing are configured so that the valise flaps shrink before the lacing shrinks when heat is applied.

6. The packing system of claim 1 , wherein the valise flaps each include a reinforced section, wherein holes are defined in the reinforced section for receiving the lacing.

7. The packing system of claim 6 , comprising grommets within respective ones of the holes.

8. A packing system for a slide of an aircraft evacuation system, the packing system comprising:
a rigid packboard having a first side end and a second side end that opposes the first side end;
a first valise flap set having a first outer end and a first inner end, the first outer end connected to the first side end of the rigid packboard,
the first valise flap set including a first set of layers of valise flaps that are layered one on top of the other between a first innermost layer and a first outermost layer and joined to one another at the first outer end and the first inner end;
a second valise flap set having a second outer end and a second inner end, the second outer end connected to the second side end of the rigid packboard,
the second valise flap set including a second set of layers of valise flaps that are layered one on top of the other between a second innermost layer and a second outermost layer and joined to one another at the second outer end and the second inner end; and
lacing for tying together the first inner end of the first valise flap set and the second inner end of the second valise flap set,
wherein the first valise flap set and the second valise flap set are formed of a heat shrink material.

9. The packing system of claim 8 , wherein the innermost layer of each of the valise flap sets is formed of a different heat shrink material than the outermost layer.

10. The packing system of claim 9 , wherein the valise flap sets are configured so that the innermost layer of each of the valise flap sets shrinks before the outermost layer when heat is applied.

11. The packing system of claim 8 , wherein adjacent layers of the valise flap sets are sized differently from one another.

12. The packing system of claim 8 , wherein the outermost layer of each of the valise flap sets defines one or more perforations.

13. The packing system of claim 12 , wherein each layer other than the innermost layer of each of the valise flap sets defines the one or more perforations, and wherein perforations in adjacent layers are offset from one another.

14. The packing system of claim 8 , wherein the first valise flap set and the second valise flap set are formed of a same heat shrink material.

15. The packing system of claim 14 , wherein the lacing is formed of a heat shrink material.

16. The packing system of claim 15 , wherein the heat shrink material of the valise flap sets differs from the heat shrink material of the lacing.

17. The packing system of claim 15 , wherein each of the valise flap sets includes a reinforced section, wherein holes defined in each reinforced section are configured for receiving the lacing.

18. The packing system of claim 8 , wherein each of the valise flap sets and the lacing are configured so that each of the valise flap sets shrinks before the lacing shrinks when heat is applied.

19. A method of packing a folded slide of an aircraft evacuation system, comprising:
positioning the folded slide onto a rigid packboard of a packing system;
positioning, over the folded slide, valise flaps that oppose one another, wherein the valise flaps are connected to side ends of the rigid packboard that oppose one another, and wherein the valise flaps are formed of a heat shrink material;
connecting the valise flaps to one another with lacing; and
applying heat to the valise flaps to shrink the valise flaps.

20. The method of claim 19 , further comprising applying heat to the lacing such that it shrinks at a rate that differs from a valise shrinkage rate of the valise flaps when heat is applied.
