Abstract
Abstract A wooden suspending ceiling system is disclosed comprising a plurality of parallel wooden runners extending in one direction, and a plurality of parallel wooden cross members supported by the runners and extending in a second direction perpendicular to the runners defining a generally rectangular grid system having a plurality of openings therein. Ceiling panels, lighting fixtures, or air vents are supported by the runners and cross members defining the rectangualr grid system and closing the openings therein. The runners and the cross members have an upper face and a bottom face, with the bottom face being viewable from below. The upper face of both the runner and cross members comprises a central portion with a groove on each side of the central portion, and with a lip outboard of each of the grooves. The inner surface of the lip defines the outer surface of the groove on each side of the central portion, and with a lip outboard of each of the grooves. The inner surface of the lip defines the outer surface of the groove, and the outer surface of each of the lips defines a vertical side of the runner or cross member. The cross member has an integral hook extending out beyond each end thereof for cooperating with an adjacent side, lip, and groove of a respective runner thereby to positively interconnect the cross member to the runners and to support the cross members on the runners.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
229 words
A wooden suspended ceiling system suspended at a desired level from the overhead structure of a building, said system comprising a plurality of one-piece, integral wooden runners extending in one direction, and a plurality of one-piece, integral wooden cross members supported by said runners and extending in a second direction relative to said runners thus defining a plurality of openings, a plurality of ceiling panels supported by said runners and said cross members with said ceiling panels closing said openings, said runners and cross members having an upper face and a bottom face, with the bottom faces thereof being viewable from below, said upper face of both said runner and said cross members comprising a central sill portion, a longitudinal groove on the sides of said central sill portion of the runners, a lip outboard of said grooves with the inner surfaces of said lips defining the outer surfaces of said grooves, and with the outer vertical surfaces of said central portions defining the inner surfaces of said grooves, the outer surface of each said lips defining the outermost sides of said runners, said cross members having integral wooden means extending out beyond the end thereof for cooperating with an adjacent side, lip, and groove of a respective said runner thereby to positively interconnect said cross member to said runner and to support said cross member on said runner.
Claim 2
Dependent Claim
229 words
A wooden suspended ceiling system suspended at a desired level from the overhead structure of a building, said system comprising a plurality of one-piece, integral wooden runners extending in one direction, and a plurality of one-piece, integral wooden cross members supported by said runners and extending in a second direction relative to said runners thus defining a plurality of openings, a plurality of ceiling panels supported by said runners and said cross members with said ceiling panels closing said openings, said runners and cross members having an upper face and a bottom face, with the bottom faces thereof being viewable from below, said upper face of both said runner and said cross members comprising a central sill portion, a longitudinal groove on the sides of said central sill portion of the runners, a lip outboard of said grooves with the inner surfaces of said lips defining the outer surfaces of said grooves, and with the outer vertical surfaces of said central portions defining the inner surfaces of said grooves, the outer surface of each said lips defining the outermost sides of said runners, said cross members having integral wooden means extending out beyond the end thereof for cooperating with an adjacent side, lip, and groove of a respective said runner thereby to positively interconnect said cross member to said runner and to support said cross member on said runner.
Claim 3
Dependent Claim
24 words
A wooden suspended ceiling system as set forth in claim 1 wherein said runner and cross members are of substantially the same cross section.
Claim 4
Dependent Claim
101 words
A wooden suspended ceiling system as set forth in claim 1 wherein said integral interconnecting means comprises an integral hook portion of said central portion of said cross member extending endwise out beyond the end of said cross member a distance substantially equal to the distance from the outer side of said runner to the vertical side of said central portion of said runner, said cross member hook portion having a transverse groove in the bottom face thereof for receiving said lip of said runner, and a downwardly extending finger for being received in a respective said groove of said runner.
Claim 5
Dependent Claim
22 words
A wooden suspended ceiling system as set forth in claim 3 further comprising fastener means interconnecting said hook portion to said runner.
Claim 6
Dependent Claim
43 words
A wooden suspended ceiling system as set forth in claim 1 wherein said bottom face of said runner and said cross member has a decorative recess therein for accentuating the visual depth of said runners and said cross members when viewed from below.
Claim 7
Dependent Claim

A wooden suspended ceiling system as set forth in claim 5, wherein said decorative recess extends transversely of said runner and cross member a distance greater than the width of said central portion such that said decorative recess extends entirely across said central portion and at least in part across said lips on each side of said central portion.
Claim 8
Dependent Claim
47 words
A wooden suspended ceiling system as set forth in claim 1 further comprising molding means at the intersection of said ceiling system and the upper reaches of the vertical walls of a room for accommodating and for supporting the outermost ends of said runners and cross members.
Claim 9
Dependent Claim
47 words
A wooden suspended ceiling system as set forth in claim 7 wherein said molding means comprises a horizontal molding member secured to said wall having an upper face coplanar with the bottom faces of said members and cross members for supporting the latter relative to said wall.
Claim 10
Dependent Claim
39 words
A wooden suspended ceiling system as set forth in claim 1 wherein said ceiling panel is a vaulted panel having a central recess therein at or above the level of said upper surfaces of said runners and cross members.
Claim 11
Dependent Claim
102 words
A wooden suspended ceiling system as set forth in claim 9 wherein said vaulted panels comprise a rectangular frame with mitered corners of a suitable crown molding having a bottom horizontal surface, a downwardly facing inner surface inclined upwardly and inwardly from said bottom surface of said vaulted panel to a generally horizontal upper surface, said vaulted panel having a central panel secured to the upper surfaces of said frame, with said bottom horizontal surfaces of said frame bearing upon the upwardly facing lip surfaces of said cross members and said runners defining a ceiling panel opening within said ceiling panel system.
Claim 12
Dependent Claim
23 words
A wooden suspended ceiling as set forth in claim 9 wherein said central panel of said vaulted ceiling panel is of lattice construction.
