Abstract

In the processes for the production and installation of a pane of glass with a frame, in particular on a vehicle part, the frame is produced as a plastics molding in the form of a closed ring. In these processes, a first bearing surface for the pane of glass and an adhesive bonding surface for the application of an adhesive are formed integrally on one side of the frame, and a second bearing surface for placing against the vehicle part is formed integrally on one of the other sides of the frame. In addition, either a retaining element running around along the frame or a number of anchoring elements or a second adhesive bonding surface for the application of a second adhesive are formed integrally on one of the other side of the frame. The frame may first of all be connected permanently to the pane of glass using an adhesive and then connected removably or permanently to the vehicle part together with the pane of glass by means of the retaining element or the anchoring elements or the second adhesive. The frame may also first of all be connected removably or permanently to the vehicle part by means of the retaining element or the anchoring elements or the second adhesive and then connected permanently to the pane of glass by using an adhesive.

Claims

1. A process for producing and installing a pane of glass with a frame, comprising:

producing the frame as a plastic molding in the form of a closed ring, said frame having at least two sides and first and second profile sections, the first profile section having a higher dimensional stability and greater rigidity than the second profile section;

integrally forming a first bearing surface for the pane of glass on one side of the frame, wherein the second profile section has the first bearing surface and a recess that divides the first bearing surface into two sections, the recess receiving the first profile section so that the first profile section is recessed from the first bearing surface;

integrally forming an adhesive bonding surface on the first profile section on the one side of the frame;

integrally forming a retaining element by forming (i) a retaining groove along the frame and (ii) a retaining strip that partially overlaps the retaining groove, said retaining element being integrally formed on a side other than the side where the first bearing surface is formed;

integrally forming a second bearing surface for placing against a vehicle part, the second bearing surface being formed on a side other than the side where the first bearing surface is formed;

applying a sufficient amount of adhesive to one of the adhesive bonding surface of the first profile section and an area of a surface of the pane of glass disposed adjacent to the adhesive bonding surface, to cause the adhesive to contact both the glass and the adhesive bonding surface when the glass is placed against the first bearing surface;

placing the pane of glass against the first bearing surface of the frame so that the glass is placed over and across the recess, contacting the two sections of the first bearing surface;

connecting the pane of glass to the frame by means of the adhesive;

placing the frame and pane of glass against the vehicle part by means of the second bearing surface; and

movably connecting the frame and pane of glass to the vehicle by means of the retaining element.

2. A process according to claim 1, wherein the frame is formed by an injection molding.

3. A process according to claim 1, wherein the profile sections are extruded, cut into predetermined lengths, and permanently connected together at end faces of said profile sections to one another to form the frame.

4. A process according to claim 1, wherein sealing elements for sealing relative to the vehicle part are formed integrally at least on one of the sides of the frame facing the vehicle part, the sealing elements comprising encircling sealing ribs or sealing lips.

5. A process for producing and installing a pane of glass with a frame comprising:

producing the frame as a plastic molding in the form of a closed ring, said frame having at least two sides and first and second profile sections, the first profile section having a higher dimensional stability and greater rigidity than the second profile section;

integrally forming a first bearing surface for the pane of glass on one side of the frame, wherein the second profile section has the first bearing surface and a recess that divides the first bearing surface into two sections, the recess receiving the first profile section so that the first profile section is recessed from the first bearing surface;

integrally forming an adhesive bonding surface on the first profile section on the one side of the frame;

integrally forming a retaining element by forming (i) a retaining groove along the frame and (ii) a retaining strip that partially overlaps the retaining groove, said retaining element being integrally formed on a side other than the side where the first bearing surface is formed;

integrally forming a second bearing surface for placing against a vehicle part, the second bearing surface being formed on a side other than the side where the first bearing surface is formed;

placing the frame against the vehicle part by means of the second bearing surface;

removably connecting the frame to the vehicle part by means of the retaining element;

applying a sufficient amount of adhesive to one of the adhesive bonding surface of the first profile section and an area of a surface of the pane of glass disposed adjacent to the adhesive bonding surface, to cause the adhesive to contact both the pane of glass and the adhesive bonding surface when the pane of glass is placed against the first bearing surface;

placing the pane of glass against the first bearing surface of the frame so that the glass is placed over and across the recess, contacting the two sections of the first bearing surface; and

connecting the pane of glass to the frame by means of the adhesive.
