Laminated Offset Glazing
It has now been surprisingly discovered, according to the present invention, that the use of a laminated glazing panel in an offset glazing for use as a protective side window in vehicles results in a glazing that has improved resistance to breakage and removal after repeated impacts.
1 . A vehicle window, comprising:
a laminated glass panel having a laminated glass panel edge; and,
a glazing panel adhered to said laminated glass panel having a glazing panel edge, wherein said glazing panel edge is offset from said laminated glass panel edge by at least 2 millimeters.
2 . The window of claim 1 , wherein said laminated glass panel comprises a polymer sheet disposed between two layers of glass.
3 . The window of claim 2 , wherein said polymer sheet comprises a polymer selected from the group consisting of poly(vinyl butyral), polyurethane, polyvinyl chloride, poly(ethylene-co-vinyl acetate), polyethylene, polyethylene copolymers, partially neutralized ethylene/(meth)acrylic copolymers, and poly(cyclohexanedimethylene terephthalate-co-ethylene terephthalate) copolyester.
4 . The window of claim 3 , wherein said polymer sheet comprises poly(vinyl butyral).
5 . The window of claim 1 , wherein said laminated glass panel has a thickness of 3 to 6 millimeters.
6 . The window of claim 1 , wherein said laminated glass panel comprises heat strengthened glass.
7 . The window of claim 1 , wherein said laminated glass panel comprises two panes of tempered or semi-tempered glass.
8 . The window of claim 1 , wherein said glazing panel is a pane of tempered glass.
9 . The window of claim 8 , wherein said tempered glass has a thickness of 1.6 to 5.5 millimeters.
10 . The window of claim 1 , wherein said glazing panel and said laminated glass panel are adhered with poly(vinyl butyral), polyurethane, polyvinyl chloride, poly(ethylene-co-vinyl acetate), polyethylene, polyethylene copolymers, partially neutralized ethylene/(meth)acrylic copolymers, and poly(cyclohexanedimethylene terephthalate-co-ethylene terephthalate) copolyester.
11 . A method of securing a vehicle, comprising placing in an opening of said vehicle a vehicle window, comprising:
a laminated glass panel having a laminated glass panel edge; and,
a glazing panel adhered to said laminated glass panel having a glazing panel edge, wherein said glazing panel edge is offset from said laminated glass panel edge by at least 2 millimeters.
12 . The method of claim 11 , wherein said laminated glass panel comprises a polymer sheet disposed between two layers of glass.
13 . The method of claim 12 , wherein said polymer sheet comprises a polymer selected from the group consisting of poly(vinyl butyral), polyurethane, polyvinyl chloride, poly(ethylene-co-vinyl acetate), polyethylene, polyethylene copolymers, partially neutralized ethylene/(meth)acrylic copolymers, and poly(cyclohexanedimethylene terephthalate-co-ethylene terephthalate) copolyester.
14 . The method of claim 13 , wherein said polymer sheet comprises poly(vinyl butyral).
15 . The method of claim 11 , wherein said laminated glass panel has a thickness of 3 to 6 millimeters.
16 . The method of claim 11 , wherein said laminated glass panel comprises heat strengthened glass.
17 . The method of claim 11 , wherein said laminated glass panel comprises two panes of tempered or semi-tempered glass.
18 . The method of claim 11 , wherein said glazing panel is a pane of tempered glass.
19 . The method of claim 18 , wherein said tempered glass has a thickness of 1.6 to 5.5 millimeters.
20 . The method of claim 11 , wherein said glazing panel and said laminated glass panel are adhered with poly(vinyl butyral), polyurethane, polyvinyl chloride, poly(ethylene-co-vinyl acetate), polyethylene, polyethylene copolymers, partially neutralized ethylene/(meth)acrylic copolymers, and poly(cyclohexanedimethylene terephthalate-co-ethylene terephthalate) copolyester.
