Flush glass windshield reveal molding

A glass reveal molding has a U-shaped clamping portion and an umbrella-shaped crown portion. The clamping portion is positioned on a bevel edge of a glass window or the like to provide a flush appearance with the glass window or the like.

BACKGROUND AND SUMMARY OF THE INVENTION 
The present invention relates generally to edge molding for window panels 
or the like. More particularly, the present invention relates to a molding 
for a fixed window of an automobile vehicle such as a windshield, backlite 
or to a sunroof. The molding bridges the space between the edge of the 
glass panel and the adjacent body panel while providing the entire 
assembly with a flush glass appearance. 
Automotive windshields, backlites and sunroofs are commonly mounted to the 
associated vehicle body in a manner which leaves a space between the 
periphery of the glass panel and the body panel. This space is covered by 
a molding referred to as a windshield, backlite or sunroof reveal molding. 
In covering the space between the glass panel and vehicle body, the reveal 
molding serves to improve the visual appearance of the automotive vehicle 
and to reduce wind noise. 
To present the best visual appearance, reveal moldings must extend evenly 
around the space between the glass panel and body panel and must be able 
to accommodate spaces having varying widths. Reveal molding should also be 
able to curve around the radius of the glass panel without passing from 
the edge of the panel or twisting to become disengaged from the glass 
panel or body panel. Reveal molding also should resist fluttering in the 
relative wind. 
Many moldings designed for attachment to the edges of automotive glass are 
of a single, asymmetrical construction. These moldings generally do not 
provide a flush appearance. They often project above the surface of the 
window panel, backlite or sunroof. When such moldings are attached around 
the radius of a glass panel edge, the clamping pressure of the two 
opposing molding surfaces is uneven due to the difference of resistance 
between the mass of material above and below the center axis of the glass. 
This difference in resistance can cause gapping of one gripper or the 
other, resulting in a loss of uniform gripping about the radius. Loss of 
gripping can result in detachment of the molding from the glass edge and a 
rolling of the molding away from the surface of the glass or from the 
surface of the vehicle body. This result is unsightly, it defeats the 
cosmetic function of the molding and increases the possibility of the 
molding to snag and come out. 
In accordance with the present invention, the glass reveal molding has a 
generally U-shaped clamping portion which exerts substantial even gripping 
pressure on both top and bottom surfaces of the glass The molding has a 
crown that is substantially parallel to the legs of the "U" providing a 
continuous appearance. The glass has a beveled edge which enables one of 
the legs of the U-shaped clamping portion to seat on the bevel to provide 
a flush appearance with respect to the glass. Also, the crown includes a 
stabilizing tail that nests with the U-shaped clamping portion. The tail 
stabilizer prevents the crown from tilting up or down around the radius of 
the glass but the stabilizer allows the crown to seat against the vehicle 
body. This is achieved because the tail stabilizer presses against the 
U-shaped clamping portion when the molding is applied around a radius. 
Without the tail stabilizer, the crown would tip up or down when the 
molding is applied around a glass radius. 
Further understanding of the present invention will be had from the 
following description of the preferred embodiments taken in conjunction 
with the attached drawings and the appended claims

DESCRIPTION OF THE INVENTION 
Referring to the figures, a reveal molding is illustrated and indicated 
generally by the reference numeral 10. FIG. 1 shows a clamp-on glass 
molding 10 in operative association with an automobile 12 as a windshield 
reveal molding. As seen in FIG. 2, the clamp-on glass molding 10 extends 
around the sides and top of the windshield 14 to cover the space between a 
conventionally installed windshield and the body panel 15 of the 
automobile 12. Also, clamp-on glass molding 10 may be modified to fit 
around the glass panel of a sunroof 16 and modified to attach to the roof 
panel 18. It will, of course, be appreciated by those skilled in the art 
that clamp-on glass molding 10 is well suited for use as an automotive 
windshield reveal molding or backlite reveal molding, but also has molding 
uses both inside and outside the automotive field. 
Clamp-on glass molding 10 is comprised of a suitable elastomeric material 
and is an elongated molding broadly comprising, in cross-section, a 
U-shaped clamping portion 20 and a crown 22, both of which may be 
comprised of polyvinylchloride or other suitable elastomeric material as 
is common in the art. For example, clamping portion 20 and crown 22 can be 
co-extruded and comprised of polyvinylchloride of a hardness of durometer 
shore A 97 and 85, respectively. 
U-shaped portion 20 includes legs 24 and 26 positioned on opposite surfaces 
of the window glass 14. Generally, leg 26 is positioned in beveled edge 28 
of the window glass 14. The crown 22 is positioned substantially parallel 
with the legs 24 and 26. In this position, a substantially equal amount of 
mass is above and below the central plane of the glass windshield 14, see 
FIG. 3. This provides for a substantially even clamping pressure by the 
legs 24 and 26 on opposite surfaces 28 and 30 of the glass 14. The 
equalized pressure and force of the U-shaped clamping portion 20 reduces 
the problem of gapping and twisting around the radius of the windshield 
and enhances retention of the molding on the windshield without rolling or 
gapping of the molding. Thus, problems with respect to detachment of the 
molding from the glass edge or a rolling of the molding away from the 
glass edge are minimized. 
An adhesive 32, such as a foamed hot melt adhesive, may be provided for 
retention of the clamp-on glass molding 10 on the edge of the windshield 
14 during subassembly. The U-shaped clamping portion 20 also includes a 
bottom knob 34. The knob 34 is located on the leg 24 at the junction of 
the leg 24 with the web 36, which spaces the legs 24 and 26 apart from one 
another. The knob 34 enables the urethane adhesive used to hold the glass 
within the opening to mechanically lock the clamp-on glass molding 10 in 
place when the adhesive 32 sets up. 
Crown 22 provides an umbrella-shaped cover which extends across the space 
between the windshield 14 and the adjacent vehicle body panel 15. The 
crown 22 must be resilient and flexible so as to maintain an overlaying 
engagement with the associated vehicle body which may not always be in 
exact alignment. The crown 22 includes a covering portion 38 which is 
substantially parallel with the legs 24 and 26. The portion of the 
covering portion 38 over the leg 26 is of a thickness such that the 
thickness of the leg 26 and cover portion 38 is substantially equal to the 
thickness of the bottom leg 24 to provide an equal clamping force as 
explained above. 
Crown 22 also has a stabilizing tail 40 extending downward from the 
laterally median portion of the crown 22 as viewed in FIGS. 2-4. Tail 40 
enhances the resistance of the crown 22 to twisting and hence detachment 
of the crown 22 from the glass panel or body panel surface. Tail 40 is 
substantially parallel and adjacent to the web 36 and nests therewith when 
installed about a windshield. A gap 43 is formed between surface faces 42 
of crown 22 and 44 of the web 36 when clamp-on molding 10 is installed. 
Crown 22 is joined to clamping portion 20 at the end 46 of leg 26 of 
clamping portion 20. The outwardly facing surface 50 of crown 22 may carry 
a metalized mylar or other bright work as is conventional in the art. 
The outer surface 50 of crown 22 is substantially flush with the outer 
surface 52 of the glass panel 14. The bevel 28 enables leg 26 and cover 
portion 38 to be positioned thereon to provide a flush engagement of the 
outer surface 50 of crown 22 with the outer surface 52 of the glass 14. 
This flush abutting engagement provides aesthetic enhancement of the 
glass. 
Clamp-on molding 10 is well adapted to be a windshield reveal molding. 
Clamp-on molding 10 can accommodate uneven edges of glass, as is 
illustrated in FIGS. 1 and 2, and is commonly found in the art, without 
becoming twisted or otherwise disengaged. Furthermore, clamp-on molding 10 
can be easily installed and is stable once installed to resist 
disengagement due to temperature extremes, wind or the like. Clamping 
portion 20 uniformly engages the glass panel edge while crown 22 uniformly 
covers the space between the glass panel edge and the body panel edge. 
Returning to FIG. 2, a clamp-on molding 10 is illustrated secured to a 
sunroof 16. The molding 10 includes a U-shaped clamping portion 60 with 
legs 62 and 64 and web 66. The leg 64 is positioned on the bevel 68 of the 
sunroof 16. The crown 70 is substantially parallel to the leg 64 and 
continuous therewith. The bottom surface of the crown has a bead 72 which 
seats in a groove 74 of a sunroof retaining rim 78. The sunroof 16 may be 
of the horizontal sliding type or of the vertical pop out or adjustable 
type. The molding of the present invention would work equally as well on 
either type of sunroof. 
Now referring to FIG. 4, an alternate embodiment of the present invention 
is illustrated and indicated generally by the numeral 100. Clamp-on glass 
molding 100 is shown in FIG. 4 in operative association with an automotive 
vehicle body panel 112 and an automotive windshield 114. Clamp-on glass 
molding 100 broadly comprises a U-shaped clamping portion 116 and a crown 
118. U-shaped clamping portion 116 has legs 124 and 126 which have 
surfaces 128 and 130 clampingly engaging against opposing surfaces of 
windshield 114. Leg 126 clampingly engages with bevel portion 128 of the 
glass 114. U-shaped clamping portion 116 is analogous in form and function 
to clamping portion 20 of clamp-on glass molding 10 and is symmetrical in 
cross-section with about an equal mass above and below the central plane 
of the windshield 114. The U-shaped clamping portion 116 includes a bottom 
knob 132. The bottom knob 132 allows the windshield urethane bead 134 to 
hold the glass within the opening to mechanically lock the clamp-on glass 
molding 100 in place when the urethane material sets up. 
Crown 118 is generally umbrella shaped and has a stabilizing tail 136 which 
is substantially parallel with the web 138 of the U-shaped portion 116. 
The crown 118 joins the U-shaped clamping section at the tail 136. The 
crown 118 extends from the junction of the leg 126 and web 138 
substantially parallel with the leg 126 The outer surface 140 of leg 126 
is substantially flush with the glass surface 142 providing a 
substantially continuous appearance and surface. 
While the above description sets forth preferred embodiments of the present 
invention, it will be apparent to those skilled in the art that the 
present invention is subject to modification, variation and alteration 
within the scope and spirit of the following claims.
