Abstract:
An inflatable bed adapted to be disposed on a support surface, said inflatable bed comprising:a plastic top sheet having a top surface, a bottom surface, and an outer periphery; a plastic bottom sheet disposed under said top sheet and having a lower end that is adapted to be disposed on the support surface, and an outer periphery; a plastic partition interposed between said top and bottom sheets and having an outer periphery that is spaced apart from and that is disposed between said outer peripheries of said top and bottom sheets so as to be adapted to define a concave air bag among said bottom sheet, said partition, and the support surface; a plastic pull band unit for connecting fixedly said bottom surface of said top sheet to an assembly of said bottom sheet and said partition; a plastic annular surrounding sheet disposed around said top sheet, said bottom sheet, and said partition and connected fixedly to said outer peripheries of said top sheet, said bottom sheet, and said partition so as to define an upper air chamber that is disposed among said top sheet, said partition, and said surrounding sheet and that is disposed above said concave air bag, and an annular lower peripheral air chamber that is disposed among said partition, said surrounding sheet, and said bottom sheet and that is disposed around said concave air bag; and an inflatable unit operable so as to introduce air into said upper air chamber and said annular lower peripheral air chamber; whereby, when a person moves onto said top surface of said top sheet, air is ejected from said concave air bag via a space between said bottom sheet and the support surface so that said bed acts as a suction cup, thereby fixing said bed relative to the support surface.
