Adhesively bonded window and hardware assembly
View Patent ↗An adhesively bonded window and hardware assembly includes a window member ( 12 ) presenting a surface ( 12 a ), a hardware member ( 14 ) having a flange ( 14 a ) and a projecting portion ( 14 b ) contiguous with and projecting from the flange, an adhesive member ( 18 ) disposed between the flange and the surface of the window member and adhesively bonding the hardware member ( 14 ) to the window member ( 12 ), and a sealing member ( 20 ) that envelopes part of the flange, fully surrounds the adhesive member, and bonds to and seals against the surface of the window member. The sealing member ( 20 ) serves to protect the adhesive member ( 18 ) from heat and humidity in the surrounding environment. The sealing member ( 20 ) can comprise an overmolded member formed of a polymer material.
1. An adhesively bonded window and hardware assembly, comprising:
a window member presenting a surface;
a hardware member comprising a flange and a projecting portion contiguous with the flange, the flange defining opposite first and second surfaces both of which join with a peripheral edge surface of the flange, the projecting portion projecting from the first surface in a direction away from the opposite second surface;
an adhesive member disposed between the second surface of the flange and the surface of the window member and adhesively bonding the hardware member to the window member, the adhesive member having a smaller footprint than that of the flange such that a peripheral edge portion of the second surface of the flange is free of the adhesive member; and
a sealing member that envelopes part of the flange, fully surrounds the adhesive member, and bonds to and seals against the surface of the window member, the sealing member contacting at least part, with respect to a radial direction of the hardware member, of the first surface of the flange, contacting all of the peripheral edge surface of the flange, and contacting at least part, with respect to said radial direction, of the peripheral edge portion of the second surface of the flange, and the sealing member extending continuously and completely about the flange and the adhesive member in a circumferential direction such that the sealing member serves to protect the adhesive member from heat and humidity in the surrounding environment.
2. The adhesively bonded window and hardware assembly of claim 1 , wherein the sealing member comprises an overmolded member formed of a polymer material.
3. The adhesively bonded window and hardware assembly of claim 2 , wherein the polymer material comprises a thermosetting polymer.
4. The adhesively bonded window and hardware assembly of claim 3 , wherein the overmolded member is formed by reaction injection molding.
5. The adhesively bonded window and hardware assembly of claim 2 , wherein the polymer material comprises polyvinyl chloride.
6. The adhesively bonded window and hardware assembly of claim 2 , wherein the polymer material comprises a thermoplastic elastomer.
7. The adhesively bonded window and hardware assembly of claim 1 , further comprising a black ceramic layer on the window member and forming the surface of the window member, the black ceramic layer protecting the adhesive member from ultraviolet radiation transmitted through the window member.
8. The adhesively bonded window and hardware assembly of claim 1 , wherein the window member comprises a piece of vehicular glazing.
9. The adhesively bonded window and hardware assembly of claim 8 , wherein the hardware member comprises a mounting stud.
10. The adhesively bonded window and hardware assembly of claim 1 , wherein the adhesive member comprises an adhesive selected from the group consisting of two-component urethane adhesives, single-component urethane adhesives, epoxies, acrylate polymers, acrylate copolymers, silicones, and combinations thereof.
11. The adhesively bonded window and hardware assembly of claim 10 , wherein the adhesive member comprises a structural bonding material.
12. The adhesively bonded window and hardware assembly of claim 11 , wherein the structural bonding material comprises a tape.
