Abstract
An inflatable bed includes a bedstead assembly, a mattress assembly, and an electrical air pump unit. The mattress assembly is disposed on and above the bedstead assembly, and includes a top sheet, a bottom sheet disposed under the top sheet, and a plurality of surrounding sheets interconnecting the top and bottom sheets to form a plurality of air chambers, which are not in fluid communication with each other. Each of the air chambers is defined among the top sheet, the bottom sheet, and a respective one of the surrounding sheets. The electrical air pump unit is disposed on the bedstead assembly, and is operable to inflate the air chambers individually so that air pressures in the air chambers may be different.
Claims26
An inflatable bed comprising:
- a bedstead assembly;
- a mattress assembly disposed on and above said bedstead assembly and including a top sheet, a bottom sheet disposed under said top sheet, and a plurality of surrounding sheets interconnecting said top and bottom sheets to form a plurality of air chambers, which are not in fluid communication with each other, each of said air chambers being defined among said top sheet, said bottom sheet, and a respective one of said surrounding sheets;
- an electrical air pump unit disposed at least partially within said bedstead assembly and in fluid communication with said air chambers, said electrical air pump unit being operable to inflate said air chambers individually so that air pressures in said air chambers may be different;
- and
- a covering unit for receiving said top and bottom sheets and said surrounding sheets therewithin, said covering unit including an upper covering member, a lower covering member, and a zipper unit for interconnecting said upper and lower covering members, said zipper unit including upper and lower zipper halves attached respectively to said upper and lower covering members and interconnected removably;
- wherein said covering unit further includes a surrounding member disposed between said upper and lower covering members, said surrounding member including four sponge bars arranged to form a rectangular frame, and four corner positioning members disposed between said upper and lower covering members for supporting four corners of said rectangular frame, respectively, and
- wherein each of said corner positioning members is formed with an integral positioning post inserted into a corresponding one of said sponge bars such that any two adjacent ones of said sponge bars are positioned relative to each other.
