Title:
INFLATABLE BED HAVING STABLE POSITION DURING USE
Document Type and Number:
WIPO Patent Application WO/2021/026719
Kind Code:
A1
Abstract:
An inflatable bed having a stable position during use, the bed comprising an upper piece (1) and a lower piece (2) disposed spaced apart, and an enclosing band (3) enclosing and fixed at an outer peripheral side between the upper piece (1) and the lower piece (2). The upper piece (1), the lower piece (2), and the enclosing band (3) form a closed air chamber (4). The lower piece (2) comprises an elastic polymer layer (21). The enclosing band (3) comprises a high-strength support fabric layer (32). The lower piece (2) has greater elasticity than the enclosing band (3), and the enclosing band (3) has greater rigidity than the lower piece (2). A shaping pulling band (5) is connected between the elastic polymer layer (21) and an inner layer of the enclosing band (3) adjacent thereto, and the shaping pulling band (5) is disposed along a peripheral side of the lower piece (2). An inward suction cavity (6) recessed toward the air chamber (4) is formed on a surface of the lower piece (2) under the action of a pulling force of the shaping pulling band (5). The invention enables cooperative shaping of the elastic lower piece (2), the rigid enclosing band (3), and the inward suction cavity (6), thereby improving positional stability of the inflatable bed during use.
