DEFINITION

Classification: 5/678

With frame means supporting or surrounding a removable bladder:

(under subclass 665) Waterbeds or associated devices including a boxlike construction that holds the liquid enclosing structure above a floor or encompasses the liquid enclosing structure perimeter, with the construction located outside the liquid enclosing structure.

(1) Note. Frame structures in this subclass are often made of wooden boards.

(2) Note. This subclass may include waterproof liners placed between a bladder and a frame to contain any liquid that may spill when the bladder ruptures.

(3) Note. This subclass may include permanent or removable covers or caps for frame elements to cushion hard portions or edges of frames, thereby providing a softer, more yielding support for a user.
