Abstract

A floating bed includes a body having four edges, including an upper edge, a lower edge, and two side edges. The body is optionally made from foam materials or foam rubber materials, such as polyethylene (PE) or ethylene vinyl acetate (EVA). The body has first and second surfaces that include a plurality of transverse concave and convex ridges that are optionally evenly distributed. Each concave ridge on the first surface optionally corresponds to a convex ridge on the second surface, and each convex ridge on the first surface optionally corresponds to a concave ridge on the second surface.

Claims (34)

1. A floating bed, comprising:

a body comprising a single piece of foam material or a foam rubber material, wherein the foam material is polyethylene (PE) or ethylene vinyl acetate (EVA), with the body comprising:

a first surface having a plurality of transverse concave and convex ridges; and

a second surface, opposite the first surface, having a plurality of transverse concave and convex ridges, wherein the transverse convex and concave ridges are substantially evenly distributed, and wherein:

(i) each concave ridge on the first surface corresponds to a convex ridge on the second surface; and

(ii) each convex ridge on the first surface corresponds to a concave ridge on the second surface; and

a first longitudinal seam adjacent to a first side edge and a second longitudinal seam adjacent to a second side edge, each longitudinal seam running lengthwise along the body and perpendicular to the transverse concave and convex ridges.

2. The floating bed of claim 1 , wherein the floating bed includes an upper edge and a lower edge.

3. The floating bed of claim 2 , wherein the upper edge is foldable and attachable to the first or second surface of the body to form a headrest.

4. The floating bed of claim 3 , wherein the upper edge is permanently attached to the first or second surface of the body.

5. The floating bed of claim 3 , wherein the upper edge is removably attached to the first or second surface of the body via one or more fastening elements.

6. The floating bed of claim 3 , further comprising an inflatable tube within the headrest to provide support for the headrest.

7. The floating bed of claim 2 , wherein an inflatable pillow is removably attached to the body near the upper or lower edge.

8. A method for making a floating bed body comprising:

providing a sheet made of polyethylene (PE) or ethylene vinyl acetate (EVA) and having a first surface and an opposing second surface;

heating the sheet at a temperature that brings the foam or foam rubber material its deforming point;

adjusting the thickness of the heated sheet to modify its buoyancy;

placing the heated sheet in a press mold having transverse convex and concave projections;

compressing the press mold to form a plurality of transverse concave and convex ridges in each of the first and second surfaces to form a floating bed, wherein the transverse convex and concave ridges are substantially evenly distributed, and wherein:

(i) each concave ridge on the first surface corresponds to a convex ridge on the second surface; and

(ii) each convex ridge on the first surface corresponds to a concave ridge on the second surface; and

removing the pressed floating bed body from the press mold.

9. The method of claim 8 , wherein the sheet is heated at a temperature of approximately 150-230 degrees Celsius.

10. The method of claim 9 , wherein the sheet is heated for a time of approximately 3-7 minutes.

11. The method of claim 8 , further comprising cutting the sheet to a size of approximately 200×71×4 cm before heating the sheet.

12. The method of claim 8 , further comprising trimming the edges of the pressed floating bed body after removing the bed body from the press mold.

13. A floating bed, comprising:

a body comprising a single piece of foam material or a foam rubber material, with the body comprising:

a first surface having a plurality of transverse concave and convex ridges; and

a second surface, opposite the first surface, having a plurality of transverse concave and convex ridges, wherein the transverse convex and concave ridges are substantially evenly distributed, and wherein:

(i) each concave ridge on the first surface corresponds to a convex ridge on the second surface; and

(ii) each convex ridge on the first surface corresponds to a concave ridge on the second surface;

a first longitudinal seam adjacent to a first side edge and a second longitudinal seam adjacent to a second side edge, each longitudinal seam running lengthwise along the body and perpendicular to the transverse concave and convex ridges; and

an upper edge and a lower edge, wherein the upper edge is permanently attached to the first or second surface of the body to form a headrest.
