Application No. 09/833,831
The claimed subject matter
Claim 1, the only independent claim on appeal, reads as follows:
A measurement system incorporated into a cross runner for use in a
suspended grid structure extending within a walled enclosure, the grid structure
supporting a plurality of ceiling tiles, said system comprising:
a plurality of main runners and means for suspending said main runners
from a ceiling in parallel, spaced apart and elongated extending fashion, each of
said main runners defining, in cross section, a tile support lip and a web
extending from said support lip, a plurality of elongated channels being formed
through first and second opposite faces of said web at axially spaced apart
intervals and between a first end and a second end;
a plurality of interconnecting wall angles secured to selected surfaces of
said walled enclosure, each of said wall angles having an elongated body which
includes, in cross section, a first side and a second side extending from an
interconnecting edge with said first side;
a plurality of cross runners extending between a selected wall angle and a
selected main runner, each of said cross runners defining, in cross section, a tile
support lip and a web extending in substantially perpendicular fashion from a
midpoint of said support lip, at least one of first and second connector clips
extending from associated first and second ends of each of said cross runners;
and
a measurement indicia applied at selected intervals along each of said
cross runners and being capable of identifying, upon positioning of said cross
runner, a correct linear and measured distance between said selected main
runner and said wall angle and which is less than an overall length of said cross
runner, an end portion of said cross runner capable of being sectioned prior to
inserting engagement of a selected and remaining connector clip with said
selected main runner and abutting engagement of said sectioned end portion
with said wall angle, said measurement indicia further comprising a first linear
marking at a center point of each of said cross runners, at least one additional
linear marking extending from said center point and at equidistant locations
towards said first and second ends of said cross runner.
