Abstract

An inflatable bed includes an envelope having first and second walls and a surrounding wall that cooperates with the first and second walls to define an air chamber, a flexible partition sheet disposed within the air chamber, a reinforcing sheet overlying the partition sheet and having a marginal end, a plurality of first retention members connected between the first wall of the envelope and the partition sheet, and a plurality of second retention members connected between the second wall of the envelope and the reinforcing sheet. The flexible partition sheet has a peripheral end welded to the surrounding wall and dividing the air chamber into first and second air chambers. The reinforcing sheet is welded to the partition sheet solely at the marginal end.

Claims

1. An inflatable bed comprising:

an envelope having a first wall, a second wall opposite to said first wall, and a surrounding wall interconnecting said first and second walls and cooperating with said first and second walls to define an air chamber;

a flexible partition sheet disposed within said air chamber, and having a peripheral end welded to said surrounding wall and dividing said air chamber into first and second air chambers;

a reinforcing sheet overlying said partition sheet and having a marginal end, said reinforcing sheet being welded to said partition sheet solely at said marginal end, wherein said reinforcing sheet has an area smaller than that of said partition sheet;

a plurality of first retention members connected between said first wall and said partition sheet; and

a plurality of second retention members connected between said second wall and said reinforcing sheet.

2. An inflatable bed comprising:

an envelope having a first wall, a second wall opposite to said first wall, and a surrounding wall interconnecting said first and second walls and cooperating with said first and second walls to define an air chamber;

a flexible partition sheet disposed within said air chamber, and having a peripheral end welded to said surrounding wall and dividing said air chamber into first and second air chambers, wherein said flexible partition sheet is formed with a plurality of through holes to spatially intercommunicate said first and second air chambers;

a reinforcing sheet overlying said partition sheet and having a marginal end, said reinforcing sheet being welded to said partition sheet solely at said marginal end;

a plurality of first retention members connected between said first wall and said partition sheet; and

a plurality of second retention members connected between said second wall and said reinforcing sheet.
