Abstract

Claims (35)

1. An apparatus, comprising:

a first panel;

a second panel;

a third panel;

a fourth panel, when in an erected position, the first panel, the second panel, the third panel and the fourth panel form a first cross-section at a first height and a second cross-section at a second height, the first cross-section having a greater area than the second cross-section, the first height lower than the second height; and

a first stop extending between a first vertex between the first panel and the third panel and a second vertex between the second panel and the fourth panel, the first stop to prevent movement of the first panel about the first vertex, the first stop is at an acute angle with reference to a central axis of the first cross-section.

2. The apparatus of claim 1 , further including a first substrate and a second substrate, the first substrate including the first panel and the second panel, the second substrate including the third panel and the fourth panel.

3. The apparatus of claim 2 , wherein the first substrate has a top edge with a slot, the slot to fit a top element.

4. The apparatus of claim 2 , wherein the first substrate has a first flap and a second flap, and the second substrate has a third flap and a fourth flap, the first flap coupled to the third flap to form the first vertex and the second flap coupled to the fourth flap to form the second vertex.

5. The apparatus of claim 2 , wherein the first panel is separated from the second panel by a first line of weakness and the third panel is separated from the fourth panel by a second line of weakness.

6. The apparatus of claim 1 , further including a second stop extending between the first vertex and second vertex, the first stop smaller in length than the second stop.

7. An apparatus, including:

a shroud including a first substrate, a second substrate and an interior formed between the first substrate and the second substrate, the interior having a first cross-sectional area at a first height and a second cross-sectional area at a second height, the first cross-sectional area smaller than the second cross-sectional area, the first height higher than the second height;

a first stop coupled to the first substrate at the first height, the interior having a central axis, the first stop intersecting the central axis at a non-orthogonal angle; and

a second stop coupled to the second substrate at the second height, the first stop and the second stop preventing the first substrate from rotating with respect to the second substrate.

8. The apparatus of claim 7 , wherein the first substrate includes a first panel and a second panel separated by a first line of weakness, the second substrate includes a third panel and a fourth panel separated by a second line of weakness, and the interior has a polygonal cross-section.

9. The apparatus of claim 8 , wherein the first line of weakness forms a first vertex when the apparatus is erected and the second line of weakness forms a second vertex when the apparatus is erected.

10. The apparatus of claim 9 , wherein the first stop is permanently engaged with a third vertex of the shroud and removably engaged with a fourth vertex of the shroud, the third vertex and the fourth vertex formed by intersections of the first substrate and the second substrate.

11. The apparatus of claim 10 , wherein the removable engagement of the first stop is enabled by a biasing element coupled to the first stop, the biasing element intersecting with the central axis at a non-orthogonal angle.

12. The apparatus of claim 7 , wherein the first stop and the second stop are contiguous with the first substrate.

13. An apparatus, including:

a shroud including a first substrate and a second substrate;

a first stop coupled to the shroud at a first height; and

a second stop coupled to the shroud at a second height, the second stop longer in length than the first stop, the first height greater than the second height, at least one of the first stop or the second stop intersects with a central axis of the shroud at a non-orthogonal angle.

14. The apparatus of claim 13 , wherein the first stop is permanently engaged with a first vertex of the shroud and removably engaged with a second vertex of the shroud.

15. An apparatus, including:

a shroud including a first substrate and a second substrate;

a first stop coupled to the shroud at a first height; and

a second stop coupled to the shroud at a second height, the second stop longer in length than the first stop, the first height greater than the second height,

wherein the first stop is permanently engaged with a first vertex of the shroud and removably engaged with a second vertex of the shroud, the removable engagement of the first stop is enabled by a biasing element coupled to the first stop, the biasing element intersecting with a central axis of the shroud at a non-orthogonal angle.

16. The apparatus of claim 14 , wherein the first stop and the second stop are simultaneously removably engaged with the second vertex during deployment of the apparatus.

17. An apparatus, including:

a shroud including a first substrate and a second substrate;

a first stop coupled to the shroud at a first height; and

a second stop coupled to the shroud at a second height, the second stop longer in length than the first stop, the first height greater than the second height, wherein the first stop has a first edge and a second edge parallel to the first edge, the second edge having a first corner and a second corner, the first edge coupled to a first vertex of the shroud, the first corner being removably engaged with a second vertex of the shroud, and the second corner spaced from the second vertex when the first corner engages the second vertex.
