Abstract

Abstract An improved ceiling tile system comprising a molding member within which is disposed at least one ceiling tile is disclosed wherein means are provided to urge the ceiling tile downwardly and/or in a direction away from the molding member. According to the invention, the urging means comprises a unitary resilient spring clip, a resilient portion of which engages a vertical wall of the molding and then engages an opposed vertical edge of a ceiling tile and simultaneously, while in engagement with said opposed vertical edge of said ceiling tile, bears against a surface of said molding above said tile and opposed thereto.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 132 words
In an acoustical ceiling tile system comprising a molding member within which is disposed at least one fibrous acoustical ceiling tile of the type which can be pierced by a prong wherein urging means are employed to urge said fibrous acoustical ceiling tile downwardly and/or in a direction away from said molding, the improvement to simultaneously urge the fibrous acoustical ceiling tile downwardly and away from a vertical wall of said molding wherein said urging means comprises a unitary resilient spring clip, a resilient portion of which engages against a vertical wall of said molding and thence against an upper surface of a fibrous acoustical ceiling tile and simultaneously, while in engagement with said upper surface of said ceiling tile, against a surface of said molding above said tile and opposed thereto.
Claim 2
Dependent Claim 132 words
In an acoustical ceiling tile system comprising a molding member within which is disposed at least one fibrous acoustical ceiling tile of the type which can be pierced by a prong wherein urging means are employed to urge said fibrous acoustical ceiling tile downwardly and/or in a direction away from said molding, the improvement to simultaneously urge the fibrous acoustical ceiling tile downwardly and away from a vertical wall of said molding wherein said urging means comprises a unitary resilient spring clip, a resilient portion of which engages against a vertical wall of said molding and thence against an upper surface of a fibrous acoustical ceiling tile and simultaneously, while in engagement with said upper surface of said ceiling tile, against a surface of said molding above said tile and opposed thereto.
Claim 3
Dependent Claim 47 words
An acoustical ceiling tile system according to claim 1 wherein said molding is a channel molding and comprises an upper generally horizontal wall, a vertical wall integral therewith and a lower horizontal wall beneath said upper horizontal wall over which a portion of said ceiling tile rests.
Claim 4
Dependent Claim 104 words
An acoustical ceiling tile system according to claim 2 wherein said urging means comprises a strip of springingly resilient sheet material bent to engage said vertical wall, on one side of the bend and, on the other side of said bend, a portion of the vertical edge of said fibrous acoustical ceiling tile, said urging means having integral therewith a generally horizontally disposed protruding lip engaging said fibrous acoustical ceiling tile, said urging means having integral with the portion thereof bearing against the upper surface of said fibrous acoustical ceiling tile a springingly resilient sheet material springingly engaging said upper wall of said molding.
Claim 5
Dependent Claim 39 words
An acoustical ceiling tile system according to claim 3 wherein said springingly resilient sheet material engaging said upper wall of said molding is arcuately bent such that its terminal edge faces in the same general direction as said lip.
Claim 6
Dependent Claim 30 words
An acoustical ceiling tile system according to claim 3 wherein said urging means has a cutout window portion adjacent said lip corresponding in size to the size of said lip.
Claim 7
Dependent Claim 29 words
An acoustical ceiling tile system according to claim 3 wherein said lip of said urging means is formed by bending a portion of said sheet material back over itself.
Claim 8
Dependent Claim 19 words
An acoustical ceiling tile system according to claim 3 wherein said urging means engages said upper generally horizontal wall.
Claim 9
Dependent Claim 29 words
An acoustical ceiling tile system according to claim 7 wherein said urging means engages said upper generally horizontal wall by engaging a vertical edge of a turned corner thereof.
Claim 10
Dependent Claim 33 words
An acoustical ceiling tile system according to claim 1 wherein said molding comprises a vertical wall and, integral therewith, a generally lower horizontal wall over which a portion of said ceiling tile rests.
Claim 11
Dependent Claim 43 words
An acoustical ceiling tile system according to claim 9 wherein said springingly resilient sheet material which engages said upper portion of said vertical wall is bent and the bend thereof faces a space between said fibrous acoustical ceiling tile and said vertical wall.
Claim 12
Dependent Claim 102 words
An acoustical ceiling tile system according to claim 9 wherein said urging means comprises a strip of springingly resilient sheet material bent to engage said vertical wall on one side of the bend and, on the other side of said bend, a portion of the vertical edge of said fibrous acoustical ceiling tile, said urging means having integral therewith a generally horizontally disposed protruding lip engaging said fibrous acoustical ceiling tile, said urging means having integral with the portion thereof bearing against the vertical edge of said ceiling tile a springingly resilient sheet material engaging an upper portion of said vertical wall.
Claim 13
Dependent Claim 34 words
An acoustical ceiling tile system according to claim 11 wherein said urging means engages said upper portion of said vertical wall by being bent at its end over a terminal edge of said wall.
Claim 14
Dependent Claim 30 words
An acoustical ceiling tile system according to claim 11 wherein said urging means has a cutout window portion adjacent said lip corresponding in size to the size of said lip.
Claim 15
Dependent Claim 29 words
An acoustical ceiling tile system according to claim 11 wherein said lip of said urging means is formed by bending a portion of said sheet material back over itself.
Claim 16
Dependent Claim 166 words
In an acoustical ceiling tile system comprising a channel molding which channel molding comprises an upper generally horizontal wall, a vertical wall integral therewith and a lower horizontal wall, at least one fibrous acoustical ceiling tile of the type that can be pierced with a prong or fork, a portion of which ceiling tile rests on said lower horizontal wall, and an urging means to urge said ceiling tile downwardly against said lower horizontal wall and away from said vertical wall, the improvement for simultaneously urging said fibrous acoustical ceiling tile in the intended directions by a single urging means wherein said urging means comprises a springingly resilient sheet material which engages said vertical wall at a point opposed from a vertical edge of said fibrous acoustical ceiling tile, which sheet material is bent and springingly engaged at the bend against said upper horizontal wall, said sheet material engaging the material of said ceiling tile at its end opposed from that which engages said vertical wall.
Claim 17
Dependent Claim 166 words
In an acoustical ceiling tile system comprising a channel molding which channel molding comprises an upper generally horizontal wall, a vertical wall integral therewith and a lower horizontal wall, at least one fibrous acoustical ceiling tile of the type that can be pierced with a prong or fork, a portion of which ceiling tile rests on said lower horizontal wall, and an urging means to urge said ceiling tile downwardly against said lower horizontal wall and away from said vertical wall, the improvement for simultaneously urging said fibrous acoustical ceiling tile in the intended directions by a single urging means wherein said urging means comprises a springingly resilient sheet material which engages said vertical wall at a point opposed from a vertical edge of said fibrous acoustical ceiling tile, which sheet material is bent and springingly engaged at the bend against said upper horizontal wall, said sheet material engaging the material of said ceiling tile at its end opposed from that which engages said vertical wall.
Claim 18
Dependent Claim 33 words
A ceiling tile system according to claim 15 wherein said sheet material has a ceiling tile penetrating prong penetrating said tile at its end opposed from the end which engages said vertical wall.
