Abstract

The disclosed technology includes an internal support structure for providing structural stability to an inflated air mattress. The internal support structure can include a loop of material and attachment strips to attach the loop to the top and bottom panels. The internal support structure can also include attachment strips to attach the ends of the loop of material together to complete the loop. The air mattress can include a plurality of internal support structures.

First claim

What is claimed is:

1. An inflatable air mattress comprising:
a top panel;
a bottom panel;
one or more side panels attached to the top panel and the bottom panel to form a substantially airtight enclosure;
a valve configured to control ingress and egress of air from the substantially airtight enclosure; and
an internal support structure including:
a length of material having a first end and a second end, the first end overlapping the second end to cause the length of material to form a loop having an internal surface and an external surface;
a first attachment strip positioned within the loop and attached to the top panel such that the external surface of the loop abuts an internal surface of the top panel;
a second attachment strip positioned within the loop and attached to the bottom panel such that the external surface of the loop abuts an internal surface of the bottom panel; and
a third attachment strip attached to the first end and the second end.

2. The inflatable air mattress of claim 1 , wherein the third attachment strip is positioned outside the loop.

3. The inflatable air mattress of claim 1 , wherein the third attachment strip is positioned within the loop.

4. The inflatable air mattress of claim 1 further comprising a fourth attachment strip positioned proximate the first and second ends and attached to the third attachment strip.

5. The inflatable air mattress of claim 4 , wherein the fourth attachment strip is positioned within the loop.

6. The inflatable air mattress of claim 4 , wherein the fourth attachment strip is positioned outside the loop and proximate a portion of the loop opposite the first and second ends.

7. The inflatable air mattress of claim 1 wherein the internal support structure is a first internal support structure and the inflatable air mattress further comprises a second internal support structure.

8. The inflatable air mattress of claim 7 , wherein the loop of the first internal support structure is a first loop, the third attachment strip is positioned within the first loop, and a fourth attachment strip is positioned within a second loop of the second internal support structure, the fourth attachment strip being attached to the third attachment strip.

9. The inflatable air mattress of claim 1 , wherein the length of material comprises a mesh material.

10. An inflatable air mattress comprising:
a top panel;
a bottom panel;
one or more side panels attached to the top panel and the bottom panel to form a substantially airtight enclosure;
a valve configured to control ingress and egress of air from the substantially airtight enclosure; and
an internal support structure including:
a length of material having a first end and a second end, the first end overlapping the second end to cause the length of material to form a loop having an internal surface and an external surface;
a first attachment strip positioned within the loop and attached to the top panel such that the external surface of the loop abuts an internal surface of the top panel;
a second attachment strip positioned within the loop and attached to the bottom panel such that the external surface of the loop abuts an internal surface of the bottom panel; and
a third attachment strip attaching the first end to the second end and attaching the loop to a side panel of the one or more side panels.

11. The inflatable air mattress of claim 10 , wherein the length of material comprises a mesh material.

12. The inflatable air mattress of claim 10 , wherein the internal support structure is a first internal support structure and the inflatable air mattress further comprises a second internal support structure.

13. A method for manufacturing an inflatable air mattress, the method comprising:
providing a first panel;
providing a second panel;
forming an internal support structure between the first and second panels by:
forming a loop with a length of material by causing a first end of the length of material to overlap a second end of the length of material, the loop having an internal surface and an external surface;
positioning a first attachment strip and a second attachment strip inside the loop;
attaching the first attachment strip to an internal surface of the first panel such that the external surface of the loop abuts the internal surface of the first panel;
attaching the second attachment strip to an internal surface of the second panel such that the external surface of the loop abuts the internal surface of the second panel;

attaching one or more side panels to the first panel and the second panel to form a substantially airtight enclosure; and
attaching a valve to the first panel, the second panel, or the one or more side panels, the valve being configured to control ingress and egress of air from the substantially airtight enclosure.

14. The method of claim 13 , wherein (i) the first and second ends are adjacent the first panel and (ii) attaching the first attachment strip to the internal surface of the first panel comprises attaching the first and second ends to the internal surface of the first panel.

15. The method of claim 13 further comprising attaching the first end to the second end via a third attachment strip.

16. The method of claim 15 further comprising, prior to attaching the first end to the second end via the third attachment strip, positioning the third attachment strip outside the loop.

17. The method of claim 15 further comprising, prior to attaching the first end to the second end via the third attachment strip, positioning the third attachment strip within the loop.

18. The method of claim 15 further comprising attaching the first end to the second end via a third attachment strip and a fourth attachment strip, the third and fourth attachment strips being positioned such that at least one of the first end and the second end is disposed between the third and fourth attachment strips.

19. The method of claim 18 , wherein the third attachment strip is positioned outside the loop and the fourth attachment strip is positioned within the loop.

20. The method of claim 18 , wherein (i) the third attachment strip is positioned outside the loop proximate the first and second ends and (ii) the fourth attachment strip is positioned outside the loop and proximate a portion of the loop opposite the first and second ends.
