Abstract

A collapsible apparatus includes a frame member being formed from a flexible twistable material, a first membrane and a second membrane, and an inflation member. The second membrane is attachable to the first membrane.

Claims (32)

1. A collapsible apparatus, comprising;

a frame formed from a flexible twistable material;

a tube configured to enclose the frame;

a membrane having a perimeter, said frame being attached to the membrane proximate the perimeter; and

an inflation device attached to the membrane, the inflation device being offset from the perimeter portion.

2. A device, comprising:

a frame formed from a flexible twistable material, the frame being moveable between a coiled configuration when the frame is collapsed and an uncoiled configuration when the frame is expanded;

a first membrane having a perimeter;

a second membrane coupled to the first membrane proximate the perimeter, the first membrane and the second membrane collectively defining an interior portion, at least a portion of the frame being disposed between the first membrane and the second membrane; and

an inflation member accessible from outside of the first membrane and the second membrane, the inflation member configured to communicate air to the interior portion.

3. The device of claim 2 , wherein the inflation member is partially disposed within the interior portion.

4. The device of claim 2 , wherein the frame includes a first end and a second end opposite the first end, the first end of the frame being coupled to the second end of the frame while in the coiled configuration and while in the uncoiled configuration.

5. The device of claim 2 , wherein the frame is made of plastic.

6. The device of claim 2 , wherein the frame has a circular shape when in the uncoiled configuration.

7. The device of claim 2 , wherein the inflation member extends past the interior portion.

8. A device, comprising:

a frame configured to form a closed loop, the frame being moveable between a coiled configuration when the frame is collapsed and an uncoiled configuration when the frame is expanded;

a first membrane having a perimeter;

a second membrane coupled to the first membrane proximate the perimeter, the first membrane and the second membrane collectively defining a first portion and a second portion, at least a portion of the frame being disposed between the first membrane and the second membrane in the first portion; and

an inflation device, at least a portion of the inflation device being disposed within the second portion.

9. The device of claim 8 , wherein the frame includes a first end and a second end opposite the first end, the first end of the frame being coupled to the second end of the frame while in the coiled configuration and while in the uncoiled configuration.

10. The device of claim 8 , wherein the frame is made of plastic.

11. The device of claim 8 , wherein at least a portion of the inflation device is disposed outside of the first portion and the second portion.

12. A device, comprising:

a first membrane;

a second membrane coupled to the first membrane;

a spring configured to form a closed loop, the spring being moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded, at least a portion of the spring being disposed between the first membrane and the second membrane, the first membrane and the second membrane collectively defining an interior portion having an inflatable region; and

an inflation member accessible from outside of the first membrane and the second membrane, the inflation member configured to communicate air to the interior portion.

13. The device of claim 12 , wherein the spring includes a first end and a second end opposite the first end, the first end of the spring being coupled to the second end of the spring while in the coiled configuration and while in the uncoiled configuration.

14. The device of claim 12 , wherein the spring is made of plastic.

15. The device of claim 12 , wherein the inflatable region is between the first membrane and the second membrane.

16. The device of claim 12 , wherein the inflation member is configured to provide access to the inflatable region.
