Class 108
HORIZONTALLY SUPPORTED PLANAR SURFACES
Class Definition:
This class includes rigid, planar, supporting surfaces having
structure to support the surface in a horizontal plane.
Throughout the definitions of the subclasses of this class,
the supporting surface is referred to as the "surface", and
the structure which supports this surface is referred to as
the "support".
(1) Note. This class includes traylike planar supports;
i.e., horizontal planar surfaces having an upstanding flange
around the perimeter thereof when the flange is not involved
in the relationship between the surface and the support.
(2) Note. The schedule of this class was built on patents
issued since 1931. Older patents were placed in the schedule
on the basis of the total disclosure and not necessarily on
the basis of claimed subject matter.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
For a horizontal surface without claimed support means and
having face-to-face sheets with a rim, see Class 52,
subclasses 782.2+. For a surface having no claimed support
means and having a separate attached, elongated edging or
