SECTION I - CLASS DEFINITION

This class relates to devices intended to receive the human body in a prone, supine, or sitting position for the purpose of repose, examination, or treatment. This class includes, devices ordinarily known as beds, examining tables, operating tables, hammocks, cradles, cribs, cots, camp beds, groundmats, sleeping bags, and bed accessories, such as mattresses, pillows, surgical supports, and bed clothing.

SECTION II - NOTES TO THE CLASS DEFINITION

(1) Note. Excluded from this class are mosquito nets and canopies attached to or attachable to a bed or bedstead structure via a clamp, screws, bolts, or other separate, discreet fastening devices designed to be used on an existing bed (i.e., no modification of the bed or bedstead).
(2) Note. Surgical supports for all parts of the human body, and surgical supports that are adapted to support animals or parts of animals, are included in this class.
(3) Note. Art in this class has historically required that the device receive the body for the purpose of repose. Exceptions to this requirement are subclasses which include field stretchers, and subclasses which include invalid beds and surgical supports.
(4) Note. Art in this class requires some structural modification to materials to adapt them for body support. The mere recitation of a support, wherein the novelty resides in a chemical composition for the support, would not suffice for inclusion in this class; it would place the application in the appropriate composition art area.
