Abstract
Abstract The present invention generally relates to the mounting of windows in a frame, particularly to the mounting of windows of a vehicle, e.g. an automobile, in the body frame work. The invention provides a window ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and having the general cross section of an U-profile. This first bead is elastic but not plastically deformable. The first bead comprises in its interior a second bead of plastically deformable not yet cured adhesive material consisting of a substance chemically compatible to the material of the first bead. The second bead, serving as the real adhesive material, is protected from environmental influences e.g. by covering it by a protection foil which is removed just prior to mounting the window.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
151 words
A prefabricated vehicle window adapted to be directly glued into a frame, a flange or the like, comprising a primer layer applied onto an edge portion of the vehicle window; a first profiled bead consisting of an already cured adhesive material applied onto said primer layer extending along an edge portion of said vehicle window; said already cured adhesive material having elastic properties but cannot be plastically deformed; said first profiled bead having a generally U-shaped cross section whereby the two legs of the U-shaped profile have different height, a first leg remote from the edge of the vehicle window having a greater height than a second leg adjacent to the edge of the vehicle window; said first profiled bead having a tub-like recess receiving a second bead consisting of a plastically deformable and/or activatable adhesive material which is chemically compatible with respect to the material of said first profiled bead.
Claim 2
Dependent Claim
151 words
A prefabricated vehicle window adapted to be directly glued into a frame, a flange or the like, comprising a primer layer applied onto an edge portion of the vehicle window; a first profiled bead consisting of an already cured adhesive material applied onto said primer layer extending along an edge portion of said vehicle window; said already cured adhesive material having elastic properties but cannot be plastically deformed; said first profiled bead having a generally U-shaped cross section whereby the two legs of the U-shaped profile have different height, a first leg remote from the edge of the vehicle window having a greater height than a second leg adjacent to the edge of the vehicle window; said first profiled bead having a tub-like recess receiving a second bead consisting of a plastically deformable and/or activatable adhesive material which is chemically compatible with respect to the material of said first profiled bead.
Claim 3
Dependent Claim
51 words
A vehicle window according to claim 1 in which said first higher leg of said first profiled bead comprises a rib projecting toward the interior of said tub-like recess such that an edge of the frame, flange or the like into which the window has to be mounted may engage therewith.
Claim 4
Dependent Claim
26 words
A vehicle window according to claim 1 in which said second bead is fully received in the interior of said tub-like recess of said first bead.
Claim 5
Dependent Claim
40 words
A vehicle window according to claim 3 in which said second bead has an essentially triangular or trapezoidal cross section, the surface thereof adjacent to the opening of the tub-like recess ascending toward the higher leg of said first bead.
Claim 6
Dependent Claim
51 words
A vehicle window according to claim 4 in which said second bead having an essentially triangular or trapezoidal cross section has two essentially perpendicularly running faces, one face thereof resting on the ground of the tub-like recess and the other face thereof resting on the higher leg of said first bead.
Claim 7
Dependent Claim
40 words
A vehicle window according to claim 1 in which said first bead is at least partially covered by a removable cover foil such that said cover foil does not touch said second bead in the interior of said tub-like recess.
Claim 8
Dependent Claim
34 words
A vehicle window according to claim 6 in which said cover foil extends between said first and second leg of said first bead such that the tub-like recess of said first bead is sealed.
Claim 9
Dependent Claim
17 words
A vehicle window according to claim 6 in which said cover foil fully encloses said first bead.
Claim 10
Dependent Claim
21 words
A vehicle window according to claim 6 in which said cover foil is gas tight and/or moisture tight and/or light tight.
Claim 11
Dependent Claim
21 words
A vehicle window according to claim 6 in which said cover foil is adhesively but releasably connected to said first bead.
Claim 12
Dependent Claim
24 words
A vehicle window according to claim 6 in which said cover foil is a plastic foil which optionally may further comprise a metal layer.
Claim 13
Dependent Claim
17 words
A vehicle window according to claim 6 in which said cover foil is an aluminium-plastic sandwich foil.
Claim 14
Dependent Claim
21 words
A vehicle window according to claim 1 in which said first and/or said second bead consist(s) of a polyurethane adhesive material.
Claim 15
Dependent Claim
24 words
A vehicle window according to claim 1 in which said second bead consists of an adhesive material which cures under the influence of oxygen.
Claim 16
Dependent Claim
24 words
A vehicle window according to claim 1 in which said second bead consists of an adhesive material which cures under the influence of moisture.
Claim 17
Dependent Claim
26 words
A vehicle window according to claim 1 in which said second bead consists of an adhesive material which may be activated under the influence of heat.
Claim 18
Dependent Claim
30 words
A vehicle window according to claim 1 in which said second bead consists of an adhesive material which may be activated under the influence of heat and then irreversibly cures.
Claim 19
Dependent Claim
35 words
A vehicle window according to claim 1 in which said second bead consists of a slowly curing two component adhesive material. foil immediately after the step of depositing said second beam in said tub-like recess.
Claim 20
Dependent Claim
31 words
Use of the prefabricated vehicle window of claim 1 as a ready-to-mount unit adapted to be mounted in car bodies by gluing without the need of an additional mounting adhesive material.
