WIPO Patent Application WO/2021/128617
Kind Code:
A1
Abstract:
A portable air mattress. The air mattress comprises an outer peripheral sheet (11), a top sheet (12), a bottom sheet (13), and at least one air inlet and outlet component (2). The edge of the top sheet (12) is connected to the upper edge of the outer peripheral sheet (11), and the edge of the bottom sheet (13) is connected to the lower edge of the outer peripheral sheet (11). The air mattress further comprises an inner peripheral sheet (3) and at least one transverse pull sheet (4). The inner peripheral sheet (3) is surrounded by the outer peripheral sheet (11). The upper edge of the inner peripheral sheet (3) is connected to the top sheet (12), and the lower edge is connected to the bottom sheet (13). An inner air chamber and an outer air chamber are formed inside and outside the inner peripheral sheet (3). The transverse pull sheet (4) is disposed in the outer air chamber to divide the outer air chamber into at least two transverse outer air chambers. The inner side edge of the transverse pull sheet (4) is connected to the outer side of the inner peripheral sheet (3), and the outer side edge is connected to the inner side of the outer peripheral sheet (11). The transverse outer air chambers are all communicated with the inner air chamber. The transverse pull sheet can provide inward pulling force for the outer peripheral sheet, and solves the problem of side protrusion due to outward expansion of the outer peripheral sheet.
