Articulating window panel with hidden hinge for vehicles
View Patent ↗An articulating window assembly is adapted for use with a vehicle. The assembly includes a windowpane with an inner surface and a hinge adjacent to the inner surface. The hinge includes a stationary member having a pivot element with cylindrical extensions and a central portion of larger cross-sectional area than the cylindrical extensions. The hinge further includes a mounting element extending at an angle from the pivot element. A polymeric member surrounds at least a portion of the cylindrical extensions so as to permit the hinge member to articulate about the pivot axis. Optionally, the polymeric member defines a cavity adjacent the central portion on the compression side of the stationary member to provide clearance of the polymeric member when the window is opened.
1. An articulating window assembly adapted for use in a window opening of a vehicle body, the assembly comprising, in combination:
a windowpane having an inner surface, an outer surface and a peripheral edge, the inner surface having an attachment portion; and
a hinge having a window opening side and a second side which is opposite the window opening side, the hinge comprising:
a stationary member comprising a pivot element extending along a pivot axis and a mounting element extending at an angle to the pivot axis, the pivot element comprising:
a central portion from which the mounting portion extends, and
a cylindrical extension extending along the pivot axis from the central portion, the central portion having a larger cross section, taken normal to the pivot axis, than the cylindrical extension; and
a polymeric member surrounding at least a portion of the cylindrical extension and attached to the attachment portion of the windowpane, the polymeric member adapted to rotate about the pivot axis.
2. The articulating window assembly of claim 1 , wherein the pivot element further comprises two cylindrical extensions extending along the pivot axis from opposite sides of the central portion and wherein the polymeric member surrounds at least a portion of both cylindrical extensions.
3. The articulating window assembly of claim 1 , wherein a top of the central portion is level with a top of the cylindrical extension.
4. The articulating window assembly of claim 1 , further comprising a mounting collar located around the mounting element and adjacent the central portion.
5. The articulating window assembly of claim 1 , wherein the central portion fairs into the cylindrical extension.
6. The articulating window assembly of claim 1 , wherein the polymeric member has a cavity at the second side of the central portion.
7. The articulating window assembly of claim 1 wherein the polymeric member comprises at least one of an elastomer, a thermoplastic, a thermoset plastic, and mixtures thereof.
8. The articulating window assembly of claim 1 wherein the polymeric member comprises at least one of polyurethane, polyvinyl chloride, thermoplastic elastomers, acrylonitrile butadiene styrene, polymethyl methacrylate, polyamide or mixtures thereof.
9. The articulating window assembly of claim 1 , wherein the hinge further comprises a reinforcement plate having at least one arcuate portion adjacent to the cylindrical extension and adapted to cradle the cylindrical extension therein and a second portion which is embedded in the polymeric member.
10. The articulating window assembly of claim 1 , wherein the mounting portion comprises means for mounting the hinge to a vehicle.
11. The articulating window assembly of claim 10 , wherein the means for mounting the hinge to the vehicle comprises a threaded cylindrical stud.
12. The articulating window assembly of claim 1 , wherein the attachment portion of the inner surface of the windowpane comprises at least one of frit, primer or both.
13. The articulating window assembly of claim 1 , wherein the hinge does not contact the outer surface or the peripheral edge of the windowpane.
14. The articulating window assembly of claim 1 , wherein the cylindrical extension comprises one or more annular slots.
15. An articulating window assembly adapted for use in a window opening of a vehicle body, the assembly comprising, in combination:
a windowpane having an inner surface, an outer surface and a peripheral edge, the inner surface having an attachment portion;
a hinge having a window opening side and a second side which is opposite the window opening side, the hinge comprising:
a stationary member comprising a pivot element extending along a pivot axis and a mounting element extending at an angle to the pivot axis, the pivot element comprising:
a central portion from which the mounting portion extends, and
a cylindrical extension extending along the pivot axis from the central portion; and
a polymeric member attached to the attachment section of the windowpane and surrounding at least a portion of the cylindrical extension so as to permit the windowpane to articulate about the pivot axis,
wherein the polymeric member has a cavity at the second side of the central portion.
16. The articulating window assembly of claim 15 , wherein the stationary member further comprises two cylindrical extensions that share a longitudinal axis and wherein the polymeric member surrounds at least a portion of both cylindrical extensions.
17. The articulating window assembly of claim 15 , wherein the hinge further comprises a reinforcement plate having at least one arcuate portion adjacent to the cylindrical extension and adapted to cradle the cylindrical extension therein and a second portion which is embedded in the polymeric member.
18. The articulating window assembly of claim 17 , further including one or more sleeves interposed between the reinforcement plate and the cylindrical extension.
19. The articulating window assembly of claim 15 , wherein the hinge does not contact the outer surface or the peripheral edge of the windowpane.
20. A vehicle comprising an articulating window assembly, the window assembly comprising, in combination:
a windowpane having an inner surface, an outer surface and a peripheral edge, the inner surface having an attachment portion; and
a hinge having a window opening side and a second side which is opposite the window opening side, the hinge comprising:
a stationary member comprising a pivot element extending along a pivot axis and a mounting element extending at an angle to the pivot axis, the pivot element comprising
a central portion from which the mounting portion extends, and
a cylindrical extension extending along the pivot axis from the central portion, the central portion having a larger cross section, taken normal to the pivot axis, than the cylindrical extension; and
a polymeric member surrounding at least a portion of the cylindrical extension and attached to the attachment portion of the windowpane, the polymeric member adapted to rotate about the pivot axis.
21. The vehicle of claim 19 , wherein the polymeric member has a cavity at the second side of the central portion.
22. The vehicle of claim 20 , wherein the hinge does not contact the outer surface or the peripheral edge of the windowpane.
