Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 209 words
In a suspended ceiling system having spaced, parallel main runners and spaced, parallel cross runners positioned perpendicularly to said main runners to define a rectangular grid pattern for supporting rectangular ceiling tiles, each of said runners having a pair of webs and tile supporting flanges extending outwardly from the lower end portions of each of said webs to peripherally support said rectangular panel members, each of said runners further having a downwardly opening recessed area between said webs, the combination therewith of clip means carried by said main runners in underlying relationship at the intersection of said main and cross runners, said clip means being capable of spacing the tile supporting flanges of the main runners a predetermined distance apart, each clip means including normally horizontally disposed sections extending below said flanges of said main runners, an inverted upwardly extending substantially U-shaped portion between the horizontally disposed sections, said U-shaped portion engaging the inner surfaces of said webs above said flanges of said main runner, and upwardly extending fingers at the outer end of each of said horizontally disposed sections, said fingers being provided with engaging means capable of engaging the outer edges of the outwardly extending tile supporting flanges to hold the clip means in its assembled position.
Claim 2
Dependent Claim 209 words
In a suspended ceiling system having spaced, parallel main runners and spaced, parallel cross runners positioned perpendicularly to said main runners to define a rectangular grid pattern for supporting rectangular ceiling tiles, each of said runners having a pair of webs and tile supporting flanges extending outwardly from the lower end portions of each of said webs to peripherally support said rectangular panel members, each of said runners further having a downwardly opening recessed area between said webs, the combination therewith of clip means carried by said main runners in underlying relationship at the intersection of said main and cross runners, said clip means being capable of spacing the tile supporting flanges of the main runners a predetermined distance apart, each clip means including normally horizontally disposed sections extending below said flanges of said main runners, an inverted upwardly extending substantially U-shaped portion between the horizontally disposed sections, said U-shaped portion engaging the inner surfaces of said webs above said flanges of said main runner, and upwardly extending fingers at the outer end of each of said horizontally disposed sections, said fingers being provided with engaging means capable of engaging the outer edges of the outwardly extending tile supporting flanges to hold the clip means in its assembled position.
Claim 3
Dependent Claim 27 words
The suspended ceiling system of claim 1 in which said engaging means includes inwardly directed gripping means capable of securing said clip means to said main runner.
Claim 4
Dependent Claim 18 words
The suspended ceiling system of claim 1 wherein the normally horizontally disposed sections are of substantially equal length.
Claim 5
Dependent Claim 32 words
The suspension ceiling system of claim 1, wherein said U-shaped portion includes an upper end and said inner surfaces of said webs are engaged adjacent said upper end of said U-shaped portion.
Claim 6
Dependent Claim 22 words
The suspension ceiling system of claim 4, wherein said tiles are supported on upper surfaces of said flanges of said main runner.
Claim 7
Dependent Claim 28 words
The suspension ceiling system of claim 5, wherein said engaging means provided by said fingers define inwardly bowed areas which extend over said flanges of said main runner.
Claim 8
Dependent Claim 26 words
The suspension ceiling system of claim 1, wherein said U-shaped portion engages the inner surfaces of said webs remote from said flanges of said main runner.
Claim 9
Dependent Claim 33 words
The suspension ceiling system of claim 7, wherein said webs of said main runner diverge downwardly apart and said U-shaped portion defines a minimum separation angle between said webs of said main runner.
Claim 10
Dependent Claim 34 words
The suspended ceiling system of claim 1 wherein said U-shaped portion and said fingers of said clip means define a pair of spaced openings to receive said tile supporting flanges of said main runners.
Claim 11
Dependent Claim 28 words
The suspended ceiling system of claim 1 wherein said clip means is of a predetermined width to define the minimum opening between the webs of said cross runners.
Claim 12
Dependent Claim 23 words
The suspended ceiling system of claim 10 wherein said fingers of said clip means include inwardly recessed portions in the side edges thereof.
Claim 13
Dependent Claim 21 words
The suspended ceiling system of claim 11 wherein said recessed portions are positioned between upper and lower edges of said webs.
