DEFINITION

Classification: 5/665

WATERBED OR ASSOCIATED DEVICE:

(under the class definition) Subject matter comprising a structure, providing a flexible supporting surface for substantially the whole body of a user, at least a portion of the structure adapted to enclose an amount of liquid, and devices associated with such a liquid enclosing structure.

(1) Note. Waterbeds generally comprise a flexible bladder confining a liquid, with the bladder supported or surrounded by a frame structure, with the bladder adapted to provide a yieldable supporting surface for substantially the whole body of a user reclining in a generally horizontal position.

(2) Note. Associated devices include structures that are combined with waterbeds, or have been significantly modified to be used or useful with waterbeds.

(3) Note. A waterproof liner is often placed between a bladder and its surrounding frame to collect and contain any liquid that may spill upon the rupture of the bladder and would be found in this and indented subclasses.

(4) Note. Waterbeds in which another mattress, such as an air filled mattress, is placed permanently or removably on top of the liquid bladder to support the user are classified in this and indented subclasses.

(5) Note. Liquid containing supports that do not support substantially the whole body of a user are not considered waterbeds.
