Abstract

An inflatable bed is provided. The inflatable bed comprises a top sheet and a bottom sheet disposed vertically at an interval, at least one side wall, at least one first tensioning structure and at least one support structure. An upper edge of said side wall is coupled to an outer edge of said top sheet. A lower edge of said side wall is coupled to an outer edge of said bottom sheet. An upper end and a lower end of said first tensioning structure are respectively coupled to said top sheet and said bottom sheet. Said support structure is disposed in a longitudinal direction of at least one of said side walls. At least two outside edges of said support structure are respectively coupled to the side wall adjacent. At least one inside edge of said support structure is coupled to the top sheet or bottom sheet adjacent.

First claim

What is claimed is:

1. An inflatable bed, comprising:
a top sheet and a bottom sheet disposed vertically at an interval;
at least one side wall, an upper edge of said side wall being coupled to an outer edge of said top sheet, a lower edge of said side wall being coupled to an outer edge of said bottom sheet, an air chamber formed between said top sheet, said bottom sheet and said side wall;
at least one first tensioning structure disposed in said air chamber, an upper end and a lower end of said first tensioning structure being respectively coupled to said top sheet and said bottom sheet; and
at least one support structure disposed in said air chamber, said support structure being disposed in a longitudinal direction of at least one of said side walls, at least two outside edges of said support structure being respectively coupled to the side wall adjacent, at least one inside edge of said support structure being coupled to the top sheet or bottom sheet adjacent;
wherein said support structure comprises a second tensioning structure and a third tensioning structure, at least two outside edges of said second tensioning structure are respectively coupled to said at least one side wall, at least one inside edge of said second tensioning structure is coupled to said top sheet; and
wherein at least two outside edges of said third tensioning structure are respectively coupled to said at least one side wall, at least one inside edge of said third tensioning structure is coupled to said bottom sheet.

2. The inflatable bed according to claim 1 , wherein said second tensioning structure and said third tensioning structure are respectively provided with a plurality of air holes, through which an airflow passage is formed in said air chamber.

3. The inflatable bed according to claim 1 , wherein said second tensioning structure and said third tensioning structure are disposed at an interval.

4. The inflatable bed according to claim 1 , wherein said second tensioning structure comprises at least two first I-beams, an outside edge and an inside edge of each of said first I-beams are respectively coupled to said side wall and said top sheet adjacent, the at least two first I-beams are disposed at an interval.

5. The inflatable bed according to claim 4 , wherein said at least two first I-beams are spaced apart from each other at a lower surface of said top sheet.

6. The inflatable bed according to claim 4 , wherein said at least two first I-beams are disposed at an interval on an inner surface of said side wall.

7. The inflatable bed according to claim 4 , wherein said at least two first I-beams as a whole are of a continuous annular structure or a segmental annular structure.

8. The inflatable bed according to claim 1 , wherein said third tensioning structure comprises at least two second I-beams, an outside edge and an inside edge of each of said second I-beams are respectively coupled to the side wall and said bottom sheet adjacent, the at least two second I-beams are disposed at an interval.

9. The inflatable bed according to claim 8 , wherein said at least two second I-beams are spaced apart from each other at an upper surface of said bottom sheet.

10. The inflatable bed according to claim 8 , wherein said at least two second are disposed at an interval on the inner surface of said side wall.

11. The inflatable bed according to claim 8 , wherein said at least two second I-beam as a whole are of a continuous annular structure or a segmental annular structure.

12. The inflatable bed according to claim 1 , wherein said first tensioning structure, said second tensioning structure and said third tensioning structure are all made of thermoplastic plastic sheet.

13. The inflatable bed according to claim 1 , wherein one or more of said first tensioning structure, said second tensioning structure and said third tensioning structure at least partially comprise mesh, laminated plastic sheet or a threads.

14. The inflatable bed according to claim 13 , wherein two side surfaces of said mesh or said threads are at least partially coupled integrally with two opposite plastic strips, said mesh and said threads are sandwiched between the two opposite plastic strips.

15. The inflatable bed according to claim 13 , wherein two side surfaces of said mesh or said threads are at least partially coupled integrally with an U-shaped plastic strip, said mesh and said threads are sandwiched between the U-shaped plastic strip.

16. The inflatable bed according to claim 1 , wherein said first tensioning structure is coupled to said top and bottom sheets by means of high-frequency welding; said second tensioning structure is coupled to said top sheet and said side wall by means of high-frequency welding; and said third tensioning structure is coupled to said bottom sheet and said side wall by means of high-frequency welding.

17. The inflatable bed according to claim 1 , wherein a location where said top sheet is located in the inside part of an upper edge of said second tensioning structure is lower than the location where said top sheet is located in the outside part of the upper edge of said second tensioning structure.

18. The inflatable bed according to claim 1 , wherein a location where said bottom sheet is located in the inside part of a lower edge of said third tensioning structure is lower than a location where said bottom sheet is located in the outside part of the lower edge of said third tensioning structure.

19. The inflatable bed according to claim 1 , wherein said inflatable bed further comprises a built-in air pump, which is disposed on said side wall and is located between a lower edge of said second tensioning structure and an upper edge of said third tensioning structure for inflating said air chamber.

20. The inflatable bed according to claim 1 , wherein said inflatable bed further comprises an air valve, which is disposed on said side wall for the inflation and deflation of said inflatable bed.
