Abstract
Abstract In a window pane mounting apparatus, the inboard surface of the window pane (10) is provided with a first peripheral bead (42) of a room temperature curable adhesive and a second peripheral bead (44), interior of the first bead (42), of a foamable, elastomeric, hot melt adhesive. When the window pane (10) is disposed in a window opening (12), the second bead (44) presents a dam against deformation of the first bead (42) interior of the second bead (44).

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
155 words
A window pane mounting arrangement comprising: a panel defining a window opening having a peripheral flange; a window pane having a peripheral edge and adapted to be disposed in said window opening with said edge overlapping said flange by a predetermined distance; said pane having outboard and inboard surfaces; a first peripheral bead of a room temperature curable adhesive on said inboard surface of said pane within said predetermined distance of said edge, said first bead being deformable prior to cure; a second peripheral bead of a foamed, elastomeric, hot melt adhesive on said inboard surface of said pane interior of said first bead and within said predetermined distance of said edge; said first and second beads being configured such that said second bead presents a dam against deformation of said first bead interior of said second bead as said window pane is disposed in said window opening with said inboard surface confronting said flange.
Claim 2
Dependent Claim
155 words
A window pane mounting arrangement comprising: a panel defining a window opening having a peripheral flange; a window pane having a peripheral edge and adapted to be disposed in said window opening with said edge overlapping said flange by a predetermined distance; said pane having outboard and inboard surfaces; a first peripheral bead of a room temperature curable adhesive on said inboard surface of said pane within said predetermined distance of said edge, said first bead being deformable prior to cure; a second peripheral bead of a foamed, elastomeric, hot melt adhesive on said inboard surface of said pane interior of said first bead and within said predetermined distance of said edge; said first and second beads being configured such that said second bead presents a dam against deformation of said first bead interior of said second bead as said window pane is disposed in said window opening with said inboard surface confronting said flange.
Claim 3
Dependent Claim
38 words
An arrangement according to claim 1, wherein said second bead has an upper surface which contacts said flange, as said pane is disposed in said window opening, before said first bead is deformed interior of said second bead.
Claim 4
Dependent Claim
66 words
An arrangement according to claim 2, wherein said first bead has an upper surface which extends from said inboard surface of said pane beyond said upper surface of said second bead, said second bead being spaced interior of said first bead by a distance sufficient to accommodate said first bead upon contact with said flange without deformation of said first bead interior of said second bead.
Claim 5
Dependent Claim
70 words
An arrangement according to claim 2, wherein said first bead has an upper surface which extends from said inboard surface of said pane beyond said upper surface of said second bead, said first bead having a cross sectional configuration defining a space between said first and second beads sufficient to accommodate said first bead upon contact with said flange without deformation of said first bead interior of said second bead.
Claim 6
Dependent Claim
16 words
An arrangement according to claim 1, wherein said foamed hot melt adhesive is tacky upon cooling.
Claim 7
Dependent Claim
38 words
An arrangement according to claim 5, wherein said second bead has an upper surface which contacts said flange, as said pane is disposed in said window opening, before said first bead is deformed interior of said second bead.
Claim 8
Dependent Claim
66 words
An arrangement according to claim 6, wherein said first bead has an upper surface which extends from said inboard surface of said pane beyond said upper surface of said second bead, said second bead being spaced interior of said first bead by a distance sufficient to accommodate said first bead upon contact with said flange without deformation of said first bead interior of said second bead.
Claim 9
Dependent Claim
70 words
An arrangement according to claim 6, wherein said first bead has an upper surface which extends from said inboard surface of said pane beyond said upper surface of said second bead, said first bead having a cross sectional configuration defining a space between said first and second beads sufficient to accommodate said first bead upon contact with said flange without deformation of said first bead interior of said second bead.
Claim 10
Independent Claim
150 words
A method for mounting a window pane in a panel, said method comprising the steps of: applying a first peripheral bead of a room temperature curable adhesive on an inboard surface of a window pane along a peripheral edge of said pane and within a predetermined distance from said edge, said first bead being deformable prior to cure, and applying a second peripheral bead of a foamed, elastomeric, hot melt adhesive on said inboard surface of said pane along said edge, said second bead being interior of said first bead and within said predetermined distance from said edge; disposing said pane in a window opening of a panel with said edge overlapping a peripheral flange of said panel by said predetermined distance and with said inboard surface confronting said flange; and damming said first bead with said second bead against deformation of said first bead interior of said second bead.
Claim 11
Independent Claim
150 words
A method for mounting a window pane in a panel, said method comprising the steps of: applying a first peripheral bead of a room temperature curable adhesive on an inboard surface of a window pane along a peripheral edge of said pane and within a predetermined distance from said edge, said first bead being deformable prior to cure, and applying a second peripheral bead of a foamed, elastomeric, hot melt adhesive on said inboard surface of said pane along said edge, said second bead being interior of said first bead and within said predetermined distance from said edge; disposing said pane in a window opening of a panel with said edge overlapping a peripheral flange of said panel by said predetermined distance and with said inboard surface confronting said flange; and damming said first bead with said second bead against deformation of said first bead interior of said second bead.
Claim 12
Dependent Claim
15 words
The method according to claim 9, wherein said hot melt adhesive is adherent upon cooling.
Claim 13
Dependent Claim
27 words
The method according to claim 9, wherein said hot melt adhesive comprises at least one polymer and a mineral oil, and a resin, a tackifier or both.
