Class 005
BEDS
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.
(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.

body or part having an aperture or channel permitting the
circulation of fluids (such as ambient air or liquids)
between the interior and the exterior of the support, to
enhance the comfort of a user.

permit substantial movement in and out of the support. The
use of a porous cover on a support, or the use of a
conventional porous foam as the filler, that inherently
permit movement of air through their pores, is not sufficient
for classification in this subclass.

of the cover completely through the support to the surface of
the cover on the opposite side of the support, to keep the

comfortable while resting.
(1) Note. A device in this subclass is intended to be used
with an underlying support, but does not include the
underlying support and could be used without it.
(2) Note. Art in this class requires some structural
modification to materials to adapt them for body support. The

cover completely through the pad to the surface of the cover
on the opposite side of the pad to keep the pad in a
