Abstract

The embodiments relate to an active carbon cocofiber mattress with the functions of floating and life saving. The embodiment can be folded to form a floating bed. The mattress core comprises prefabricated solid and rigid cocofiber mattresses with an ultra-thick sandwiched layer sandwiched therebetween; thus, when integrated as a whole, has a specific gravity of less than about 1. On said cocofiber mattress, there is provided with a high elastic cocofiber mattress. Within the ultra-thick sandwiched layer, air holes and channels filled with active carbon are provided. Active carbon layers cover the surface of the cocofiber mattress core.

Claims

1. A multifunctional mattress comprising three Regions, Regions A, B, and C, each of the Regions comprising:

a mattress core comprising an upper rigid cocofiber layer, a lower rigid cocofiber layer, an ultra-thick layer sandwiched between the upper and lower cocofiber layers, with a specific gravity less than about 1;

a high elastic cocofiber layer on one of said rigid cocofiber layers;

a prefabricated active carbon layer on said mattress core; and

prefabricated holes disposed within the cocofiber mattress core, the prefabricated holes comprising air holes and channels, wherein the air holes are filled only with air and the channels are filled with active carbon;

wherein Region B is adjacent to Region A on one side and adjacent to Region C on the opposite side;

Region A is adapted to be folded upwards perpendicularly from Region B, Region C is adapted to be folded upwards perpendicularly from Region B, and Regions A and C are adapted to be fastened together after being folded upwards perpendicularly form Region B.

2. The multifunctional mattress according to claim 1, wherein the high elastic cocofiber mattress adheres onto the cocofiber mattress and the prefabricated active carbon layer completely covers the surface of the cocofiber mattress core, thus forming an active carbon-cocofiber mattress core.

3. The multifunctional mattress according to claim 1, wherein said prefabricated active carbon layer is formed by selecting fine active carbon of a grain shape or a strip shape, distributing the fine active carbon on an upper layer and a lower layer of non-woven fabric, and sticking the carbon and fabric together into a whole.

4. The multifunctional mattress according to claim 2, wherein the active carbon cocofiber mattress core further comprises outside packaging materials.

5. The multifunctional mattress according to claim 4, further comprising webbing at the periphery of the mattress.

6. The multifunctional mattress according to claim 1, wherein the thicknesses of the regions A,B and C are about the same.

7. The multifunctional mattress according to claim 1, wherein said ultra-thick sandwiched layer is made of EPE composite material.

8. The multifunctional mattress according to claim 1, wherein the regions A,B, and C are connected by hinged material.

9. A method of converting a mattress of claim 1 into a floating device, comprising:

folding Region A upwards perpendicularly from Region B;

folding Region C upwards perpendicularly from Region B; and

securing the positions of Regions A and C.

10. The method according to claim 9, wherein the securing position is performed by fastening safety belts positioned on Regions A and C.
