Abstract

The disclosed technology includes an internal support structure for providing structural stability to an inflated airbed. The internal support structure may include an internal support wall connected to side panels by one or more side support beams. The internal support structure may further include corner support walls and a plurality of internal support beams to provide additional support.

First claim

What is claimed is:

1. An inflatable mattress comprising:
a top panel having an interior surface and an exterior surface;
a bottom panel having an interior surface and an exterior surface;
a plurality of outermost side panels connected to one another and connected to and disposed between the top panel and the bottom panel to form an airtight chamber and define a mattress shape, each of the plurality of outermost side panels having (i) an interior surface, (ii) an exterior surface, and (iii) first, second, and third arc-shaped segments, wherein the first arc-shaped segment and the second arc-shaped segment are joined together at a first vertex, and the second arc-shaped segment and the third arc-shaped segment are joined together at a second vertex, and where any two adjacent side panels of the plurality of outermost side panels meet to form a corner having an interior surface;
an internal support wall attached to the interior surface of the top panel and the interior surface of the bottom panel, the internal support wall being air-permeable and forming a central chamber within the airtight chamber that has a shape generally equivalent to the mattress shape;
a plurality of air-permeable corner support walls, each air-permeable corner support wall extending from the interior surface of a corner formed by adjacent side panels to a respective corner of the internal support wall;
a first lateral support beam attached to a first side of the internal support wall at a first connection point and to the interior surface of a first side panel of the plurality of outermost side panels at a corresponding first connection point; and
a second lateral support beam attached to the first side of the internal support wall at a second connection point and to the interior surface of the first side panel of the plurality of outermost side panels at a corresponding second connection point,
wherein each of the first and second lateral support beams is approximately equal to a length of the first side panel.

2. The inflatable mattress of claim 1 , wherein the internal support wall is constructed from a single piece of material.

3. The inflatable mattress of claim 1 , wherein the internal support wall comprises four distinct panels, each panel comprising a single piece of material.

4. The inflatable mattress of claim 1 further comprising a plurality of internal support beams, each internal support beam extending between the top panel and the bottom panel at an angle that, when the inflatable mattress is inflated, is non-normal to the top panel and the bottom panel.

5. The inflatable mattress of claim 4 , wherein each internal support beam of the plurality of internal support beams is secured to the interior surface of the bottom panel via a first attachment strip and is secured to the interior surface of the top panel via a second attachment strip.

6. The inflatable mattress of claim 4 , wherein each internal support beam of the plurality of internal support beams is a separate piece of material.

7. The inflatable mattress of claim 4 , wherein the plurality of internal support beams is constructed from a single piece of material.

8. The inflatable mattress of claim 1 , wherein the corresponding first connection point is at the first vertex and the corresponding second connection point is at the second vertex.

9. An inflatable mattress comprising:
an outer chamber having:
four sides, each side in airtight connection with two respective adjacent sides and forming a corner with each of the two respective adjacent sides, each corner having an interior surface;
a top in air-tight connection with the four sides; and
a bottom in air-tight connection with the four sides;
an inner chamber having four inner support walls, each of the inner support walls being air-permeable and attached to the top and the bottom;
a plurality of air-permeable corner support walls, each air-permeable corner support wall extending from a respective interior surface of a corner to a respective corner of the inner chamber;
a first lateral support beam attached to a first inner support wall of the four inner support walls and to a first side of the four sides; and
a second lateral support beam attached to the first inner support wall of the four inner support walls and to the first side of the four sides;
wherein each of the first and second lateral support beams is approximately equal to a length of the respective side panel.

10. The inflatable mattress of claim 9 further comprising a plurality of internal support beams, each internal support beam extending between an interior surface of the bottom and an interior surface of the top.

11. The inflatable mattress of claim 10 , wherein each internal support beam of the plurality of internal support beams extends between the top and the bottom at an angle that, when the inflatable mattress is inflated, is non-normal to the top and the bottom.

12. The inflatable mattress of claim 10 , wherein each internal support beam of the plurality of internal support beams is secured to the interior surface of the bottom via a first attachment strip and is secured to the interior surface of the top via a second attachment strip.

13. The inflatable mattress of claim 9 wherein the first lateral support beam is attached to the first side of the four sides at a first connection point, and the second lateral support beam is attached to the first side of the four sides at a second connection point, and both of the first and second lateral support beams are attached to the first inner support wall at a common attachment point.

14. The inflatable mattress of claim 9 , wherein the first and second lateral support beams each comprise apertures.

15. The inflatable mattress of claim 9 wherein the first lateral support beam is attached to the first side of the four sides at a first connection point and the first inner support wall at a corresponding first connection point, and the second lateral support beam is attached to the first side of the four sides at a second connection point and the first inner support wall at a corresponding second connection point.

16. An inflatable mattress comprising:
an outer chamber having:
four sides, each side (i) having first, second, and third arc-shaped segments, wherein the first arc-shaped segment and the second arc-shaped segment are joined together at a first vertex, and the second arc-shaped segment and the third arc-shaped segment are joined together at a second vertex and (ii) in airtight connection with two respective adjacent sides and forming a corner with each of the two respective adjacent sides, each corner having an interior surface;
a top in air-tight connection with the four sides; and
a bottom in air-tight connection with the four sides;
an inner chamber having four inner support walls, each of the inner support walls being air-permeable and attached to the top and the bottom;
a first lateral support beam attached to a first inner support wall and to an interior surface of a first side of the four sides;
a second lateral support beam attached to a second inner support wall and to an interior surface of a second side of the four sides;
a plurality of air-permeable corner support walls, each air-permeable corner support wall extending from a respective interior surface of a corner to a respective corner of the inner chamber; and
a plurality of internal support beams, each internal support beam extending between an interior surface of the bottom and an interior surface of the top at an angle that, when the inflatable mattress is inflated, is non-normal to th
