Abstract

An expandable shade and shelter system that includes an expandable grid structure of reversibly expandable cells in a two-dimensional grid configured to collapse to a rectangular cuboid with a top surface, an anchored bottom, an anchored first end, an expandable second end, and two expandable sides. The system includes a connecting device fixed at corners of the top surface and/or the expandable second end of the structure, a vertically oriented support structure having a top and bottom ends, where the expandable grid structure is configured to expand upwardly from the second end and inwardly towards the top of the vertically oriented support structure, while the anchored first end remains anchored, to connect the connecting device to the top of the vertically oriented support structure to form a three dimensional shelter.

First claim

The invention claimed is:

1. An expandable shade and shelter system, comprising:
an expandable grid structure comprising a plurality of reversibly expandable cells surrounded by a perimeter, wherein the expandable grid structure is configured to collapse to a rectangular cuboid in which the perimeter has a top surface, an anchored bottom anchored to the ground, an anchored first end anchored to an anchor point, an expandable second end, and two expandable sides, wherein the expandable cells are disposed in a two-dimensional grid within the perimeter,
a connecting device fixed at one or both corners of the top surface and/or the expandable second end of the expandable grid structure, proximal to a location where the top surface joins the expandable second end,
a vertically oriented support structure having a top end and a bottom end, wherein the top end is configured to connect to the connecting device and the bottom end is anchored to the ground, wherein the vertically oriented support structure is disposed proximal to the anchored first end within the length of the top surface of the expandable grid structure,
wherein the expandable grid structure is configured to expand upwardly from the expandable second end and inwardly towards the top end of the vertically oriented support structure, while the anchored first end remains anchored to the anchor point, to thereby connect the connecting device to the top end of the vertically oriented support structure to form a three dimensional shelter.

2. The expandable shade and shelter system of claim 1 , wherein one or more of the reversibly expandable cells is in a form of a hexagon having six sides and two ends corresponding to the two expandable sides, wherein the two ends of each hexagon are covered.

3. The expandable shade and shelter system of claim 1 , wherein the reversibly expandable cells have open ends corresponding to the two expandable sides.

4. The expandable shade and shelter system of claim 1 , wherein the reversibly expandable cells comprise sides made of a thermoplastic polymer material.

5. The expandable shade and shelter system of claim 4 , wherein the thermoplastic polymer is a polyurethane that is compressible and flexible.

6. The expandable shade and shelter system of claim 1 , wherein the expandable grid structure comprises a plurality of reversibly expandable cells that have open ends corresponding with the two expandable sides and a plurality of reversibly expandable cells having covered ends corresponding to the two expandable sides.

7. The expandable shade and shelter system of claim 1 , wherein the vertically oriented support structure is connected to the expandable grid structure at a single point of the expandable grid structure.

8. The expandable shade and shelter system of claim 1 , wherein the top surface of the expandable grid structure is flat when collapsed to the rectangular cuboid.

9. The expandable shade and shelter system of claim 1 , wherein the vertically oriented support structure extends beyond the two expandable sides of the expandable grid structure when in an expanded configuration.

10. The expandable shade and shelter system of claim 1 , wherein the vertically oriented support structure has multiple connecting points at different heights.

11. The expandable shade and shelter system of claim 10 , wherein the connecting device in the expandable grid structure is connected to one of the multiple connecting points in the vertically oriented support structure.
