Bed cover
The present disclosure provides at least in part a bed cover comprising a plurality of heat insulating chambers having a first surface and a second surface and at least two sidewalls connecting the first surface and the second surface, the width of said first surface being greater than the width of said second surface; a plurality of heat conduits between the sidewalls of the heat insulating chambers, said heat conduits having an open and a closed position; wherein each heat insulating chamber is hingeably connected to at least one adjacent heat insulating chamber, such that the heat conduits may open and close as adjacent heat insulating chambers flex towards or away from each other.
1. A bed cover comprising:
(a) a plurality of heat insulating chambers having a first surface and a second surface and at least two sidewalls connecting the first surface to the second surface, the width of said first surface being greater than the width of said second surface;
(b) at least one bridge connecting adjacent sidewalls of adjacent heat insulating chambers, each bridge of the at least one bridge and the adjacent sidewalls defining a heat conduit therebetween, said heat conduit having an open and a closed position;
wherein each heat insulating chamber is hingeably connected to at least one adjacent heat insulating chamber, such that each heat conduit closes or opens as adjacent heat insulating chambers flex towards or away from each other.
2. The bed cover according to claim 1 , wherein the heat insulating chambers are hingeably connected at or close to the first surface.
3. The bed cover of claim 1 , wherein the plurality of heat insulating chambers are in a series parallel to a side of the bed cover.
4. The bed cover of claim 1 , wherein the heat insulating chambers have a substantially trapezoid cross-sectional shape.
5. The bed cover of claim 1 , wherein the heat insulating chambers have a substantially isosceles trapezoid cross-sectional shape.
6. The bed cover of claim 1 , wherein the sidewalls of each heat insulating chamber are connected to the second surface.
7. The bed cover of claim 1 , wherein the heat conduits form a series of triangular shaped grooves parallel to a side of the bed cover.
8. Use of a bed cover according to claim 1 , wherein the bed cover provides two different thermal maintenance values.
9. Use of a bed cover according to claim 1 , wherein the first surface of the bed cover provides a higher degree of thermal maintenance than the second surface.
10. Use of a bed cover according to claim 1 , wherein the second surface of the bed cover provides a lower degree of thermal maintenance than the first surface.
11. A method of manufacturing a bed cover according to claim 1 .
12. The bed cover of claim 2 , wherein the plurality of heat insulating chambers are in a series parallel to a side of the bed cover.
13. The bed cover of claim 2 , wherein the heat insulating chambers have a substantially trapezoid cross-sectional shape.
14. The bed cover of claim 3 , wherein the heat insulating chambers have a substantially trapezoid cross-sectional shape.
15. The bed cover of claim 2 , wherein the heat insulating chambers have a substantially isosceles trapezoid cross-sectional shape.
16. The bed cover of claim 3 , wherein the heat insulating chambers have a substantially isosceles trapezoid cross-sectional shape.
17. The bed cover of claim 4 , wherein the heat insulating chambers have a substantially isosceles trapezoid cross-sectional shape.
18. The bed cover of claim 2 , wherein the sidewalls of a heat insulating chamber are connected to the second surface.
19. The bed cover of claim 3 , wherein the sidewalls of a heat insulating chamber are connected to the second surface.
20. The bed cover of claim 4 , wherein the sidewalls of a heat insulating chamber are connected to the second surface.
