One side is affixed. The mounting surface 22e is formed over the entire length of the molding body 22, and the double-sided adhesive tape 27 is adhered over the entire length of the mounting surface 22e. Then, the other surface 27 c of the double-sided adhesive tape 27 is attached to the position of the opaque colored layer 13 of the window plate 12 along the periphery of the window plate 12. As a result, the window edge molding 20 is fixed to the back surface of the window plate 12 over substantially the entire length. Here, being fixed over the entire length is the total length of the portion adhered to the back surface of the window plate 12, for example, an extension portion in which the molding body 22 extends beyond the lower peripheral edge of the window plate 12. In some cases, it is not always necessary to provide the double-sided adhesive tape 27 at this portion. At this time, as shown in FIG. 2, the window edge molding 20 is positioned at a position where the outer surface 22 x of the panel-side flat plate-shaped portion 22 t in the molding main body 22 slightly protrudes from the outer peripheral end surface of the window plate 12 by the dimension L. The
That is, the mounting surface 22e in the molding body 22 of the window edge molding 20 corresponds to the mounting part of the present invention.

When the vehicle window assembly 10 is mounted on the window opening edge 6 of the vehicle body 1, the elastic lip 24 of the window edge molding 20 is elastic as shown by an imaginary line (two-dot chain line) in FIGS. It is deformed and elastically contacts with the side wall 6e to shield the gap SP between the outer peripheral end face of the window plate 12 and the window opening edge 6 of the vehicle body 1. The elastic lip 24 is formed integrally with the molding main body 22 on the outer surface 22x of the panel-side flat plate-like portion 22t of the molding main body 22, and extends over the entire length of the molding main body 22 along the mounting surface 22e.

In a free state before being attached to the vehicle body 1, the tip position of the elastic lip 24 is set so as to exceed the side wall portion 6e of the vehicle body 1 as shown in FIGS.
The window edge molding 20 is formed of, for example, a thermoplastic elastomer colored black (mixture of thermoplastic resin and rubber), and the elastic lip 24 is more elastic than the molding body 22. . That is, in the portion of the elastic lip 24, the mixing ratio of the thermoplastic resin to the rubber is smaller than that of the portion of the molding main body portion 22. In the window edge molding 20 according to the present embodiment, the hardness of the elastic lip 24 is set to HDA 70 of JIS K7215, and the hardness of the molding body 22 is set to 90. In addition, an adhesive layer formed of a resin that easily adheres to an adhesive sealant (sealant) on the back side portion of the molding body 22, that is, the back side of the window-side flat plate portion 22 u and the back side of the panel-side flat plate portion 22 t. 22z is provided.
The window edge molding 20 is molded in a predetermined cross-sectional shape (cross-sectional shape shown in FIG. 3 and the like) by an extrusion molding device (not shown). In addition, the code | symbol 22w in FIG. 3 represents the metal wire integrally embedded in the molding main-body part 22 of the window edge molding 20 at the time of extrusion molding.

For this reason, at the position of the corner C of the window plate 12, the upper peripheral molding 20u and the side peripheral molding 20s of the window margin molding 20 intersect with the corner C of the window plate 12 at substantially the same angle. The double-sided adhesive tape 27 adhered to the mounting surface 22e of the molding 20 is also arranged so as to intersect at substantially the same angle, and the terminals are substantially continuous. On the other hand, as described above, the window plate 12 has the circular chamfered portions 12e formed at the left and right corners C located at the boundary between the upper peripheral edge U and the left and right side peripheral edges S. For this reason, at the position of the corner C of the window plate 12, a part of the adhesive surface (other surface 27c) of the double-sided adhesive tape 27 is the chamfered portion 12e together with the corner portion (end portion) of the mounting surface 22e of the window edge molding 20. The window plate 12 is exposed from the outer peripheral end surface.

In the vehicle window assembly 10 according to the first example of the present embodiment, ultraviolet light (UV) is formed on the exposed portion of the other surface 27c of the double-sided adhesive tape 27 protruding from the outer peripheral end surface of the window plate 12 by the chamfered portion 12e of the window plate 12. For example, a non-adhesive layer 31 made of a black coating film having good weather resistance is formed. As a result, even if dust or dirt exists in the environment where the vehicle window assembly 10 is handled, the dust or dust does not adhere to the exposed portion of the double-sided adhesive tape 27. For this reason, until the vehicle window assembly 10 is attached to the opening edge 6 of the window opening 4 of the vehicle body 1 or during use of the vehicle, no dust or dirt adheres to the exposed portion of the vehicle window assembly 10. There is no problem that impairs the appearance. Moreover, since the non-adhesion layer 31 is a coating film, the non-adhesion layer 31 can be formed easily. The coating film can be formed by dissolving an acrylic urethane resin or the like in a solvent as appropriate and applying and drying a liquid paint in which an appropriate pigment such as carbon black is mixed.
Furthermore, since the color (black) of the coating film is substantially equal to the color (black) of the mounting surface 22e of the window edge molding 20, the non-adhesive layer 31 formed on the other surface 27c of the double-sided adhesive tape 27 and the window edge molding 20 A feeling of discomfort in color does not occur with the mounting surface 22e, and a good appearance is maintained. Furthermore, since it can be used regardless of the color of the double-sided adhesive tape 27, the double-sided adhesive having a preferable adhesive force between the back surface of the window plate 12 and the mounting surface 22e of the window edge molding 20. The tape 27 can be selected and used, and the options are expanded. Moreover, since the black colored coating film 15 substantially equal to the color (black) of the mounting surface 22e of the window edge molding 20 is formed on the outer peripheral end surface of the window plate 12, the non-adhesive layer 31 is further inconspicuous.
In the vehicle window assembly 10 according to the present embodiment, the terminal 20 y of the upper peripheral molding 20 u along the upper peripheral edge U at the corner C of the window plate 12 and the terminal 20 x of the side peripheral molding 20 s along the side peripheral S. Coincides with a virtual straight line T that substantially bisects the angle C of the window plate 12, and the terminals of the window edge moldings 20u and 20s are joined to each other. For this reason, the aesthetics of the upper peripheral molding 20u, the side peripheral molding 20s, and the joining portion are maintained.
Further, since the double-sided adhesive tape 27 of the upper peripheral molding 20u and the double-sided adhesive tape 27 of the side peripheral molding 20s are substantially connected to each other at the joint portion between the upper peripheral molding 20u and the side peripheral molding 20s. In C, the adhering force of the window edge molding 20 to the window plate 12 is maintained.
As the double-sided pressure-sensitive adhesive tape 27, a tape commercially available from Sumitomo 3M Ltd. under the name "Scotch mount" can be preferably used.

(Second embodiment)
As described above, in the vehicle window assembly 10 according to the first example of the present embodiment, the example in which the non-adhesive layer 31 is formed by the paint film is shown. However, as shown in FIG. It is also possible to form the non-adhesive layer 31 by sticking a sheet-like piece previously molded into a predetermined shape to the exposed portion of the double-sided adhesive tape 27. Thus, by using a sheet-like piece, the accurate outer peripheral non-adhesive layer 31 can be easily formed in a short time, and the outer shape of the non-adhesive layer 31 is different for each product of the vehicle window assembly 10. There is no variation. Further, if a sheet-like piece having an adhesive layer on the back side, such as an adhesive resin tape, is used and the back side of the sheet-like piece is attached to the other surface 27c of the double-sided pressure-sensitive adhesive tape 27, the sheet-like piece is double-sided. By sticking firmly to the other surface 27c of the tape 27, a high and stable fixing force can be obtained. Here, it is preferable that the sheet-like piece has a weather resistance as in the case of the first embodiment, and is set to a color (black) equal to the mounting surface 22e of the window edge molding 20. In addition, it is preferable that the small piece has a substantially triangular shape and has a small roundness at the corner because the corner does not start to peel off.

The other surface 27c of the double-sided pressure-sensitive adhesive tape 27 is covered with a release paper 50 (sometimes referred to as a release liner) such as a polyethylene resin tape, which is peeled and attached with a weak adhesive force. The release paper 50 is peeled off when the window edge molding 20 is adhered to the back surface of the window plate 12 by the other surface 27C of the double-sided adhesive tape 27. The release paper 50 is made of a material that does not impair the adhesiveness of the other surface 27c of the double-sided pressure-sensitive adhesive tape 27 and easily peels off. It straddles both ends 50x, 50y of each release paper 50, 50 of the double-sided adhesive tape 27 located at the corner C portion of the window edge molding 20, that is, the joint portion between the upper peripheral molding 20u and the side peripheral molding 20s. The strip-shaped tab tape 52 is stuck in a direction extending along a virtual straight line T that substantially bisects the angle C of the window plate 10. The adhesive force of the tab tape 52 to the release paper 50 is greater than the adhesive force of the release paper 50 to the double-sided adhesive tape 27. Although not shown, a non-adhesive layer is formed under the release paper 50 at the corner C as described in detail in the first embodiment. For this reason, by gripping the tab tape 52 and pulling the tab tape 52 in the center direction of the window plate 12, the upper peripheral molding 20u and the side peripheral peripheral are first peeled off easily from the non-adhesive layer portion with a weak force. The release paper 50 and 50 with the molding 20s can be peeled off at the same time. Therefore, when the tab tape 52 starts to be peeled off, it does not peel off from the release paper 50 or torn off, and the efficiency of the release paper peeling work when the window edge molding 20 is stuck to the back surface of the window plate 12. Will improve.

In addition, when the window edge molding 20 is attached to the back surface of the window plate 12, the portion corresponding to the other surface 27c (exposed portion) of the double-sided adhesive tape 27 protruding from the chamfered portion 12e of the window plate 12 is implemented. As described in the first embodiment, the non-adhesive layer 31 is formed of a coating film or a sheet-like piece.
As shown in FIG. 6, the non-adhesive layer 31 is covered with the release paper 50 together with other portions on the other surface 27 c of the double-sided adhesive tape 27, and is held to the outside. For this reason, the non-adhesive layer 31 is not damaged or soiled.
Further, as described in the first embodiment, the elastic lip 24 of the window edge molding 20 is more elastic than the molding body 22, so that it elastically contacts the panel of the vehicle body 1 when installed, and the window opening edge 6. And the elastic lip 24 can reliably shield the gap SP between the outer peripheral edge of the window plate 12 and the window plate 12.

[Third Embodiment]
Next, the manufacturing method of the window edge molding which concerns on Embodiment 3 of this invention based on FIG. 7, FIG. 8 is demonstrated.
In the manufacture of the window edge molding 20, the molding body 22 and the elastic lip 24 of the window edge molding 20 are integrally molded in a predetermined cross-sectional shape and a long straight shape from a thermoplastic elastomer by an extrusion molding device (not shown). deep. Next, one surface of the double-sided adhesive tape 27 whose other surface 27c is covered with the release paper 50 is attached to the mounting surface 22e of the molding body 22 of the window edge molding 20 over the entire length of the mounting surface 22e. Next, the molding body 22 and the elastic lip 24 and the attached double-sided adhesive tape 27 are cut together according to the length of the upper peripheral molding 20u. At this time, the terminal 20x of the double-sided adhesive tape 27 with the molding body 22 and the elastic lip 24 and the release paper 50 attached thereto is cut so as to coincide with the virtual straight line T that almost bisects the angle C of the window plate 12. (See FIG. 2). The side peripheral molding 20s is also formed in the same manner as the upper peripheral molding 20u. Next, the molding main body 22 and the elastic lip 24 of the upper peripheral molding 20u and the molding main body 22 and the elastic lip 24 of the side peripheral molding 20s are joined to each other by a method such as heat welding. Let At this time, the terminals of the double-sided pressure-sensitive adhesive tapes 27 and 27 and the release paper 50 and 50 are in a butting state.

The non-adhesive layer 31 made of a coating film is formed by applying a paint having good adhesion (adhesiveness), weather resistance, and opaque coloring, for example, black paint with an applicator 53, and preferably drying by natural drying. Next, the release paper 50 and its terminals 50x and 50y are returned to their original positions, and the other surface 27c of the double-sided adhesive tape 27 and the non-adhesive layer 31 once exposed are covered again with the release paper 50 and its terminals 50x and 50y. In this state, the manufacturing process of the window edge molding 20 is completed. The paint is not limited to liquid, and a paint film may be formed by applying a crayon-like solid paint.
Here, instead of forming the non-adhesive layer 31 with a coating film using the applicator 53, as shown in FIG. 8, the non-adhesive layer 31 may be formed by affixing a sheet-like piece 55.
From the carrier sheet, the small piece 55 is a piece of colored film having a large number of separation cuts corresponding to the outer shape of the small piece 55 in a film portion such as a wide colored film with a back-side adhesive attached on a carrier sheet having releasability. It is preferable to peel it off.

Thus, in the manufacturing method of the window edge molding 20, before the step of peeling the terminals 50x, 50y of the release paper 50 of the double-sided adhesive tape 27, the tab tape having a shape that can be gripped by the terminals 50x, 50y of the release paper 50. Since 52 is attached, a part of the release paper 50 can be easily peeled off.
In the step of forming the non-adhesive layer 31, a paint is applied or applied to the exposed portion of the double-sided adhesive tape 27 using a container and a pen-like applicator having a porous material application core at its tip. Since the non-adhesive layer 31 can be formed, the non-adhesive layer 31 can be easily formed even in a fine range or shape.
Further, in the step of forming the non-adhesive layer 31, the non-adhesive layer 31 is formed by attaching the sheet-like small piece 55 to the exposed portion of the double-sided adhesive tape 27. Can be formed.
After the non-adhesive layer 31 is formed, the partially peeled release paper 50 is returned to the original direction, and the release paper 50 is pasted on the other surface 27 c of the double-sided adhesive tape 27 at a position other than the non-adhesive layer 31. Therefore, dust and dirt do not adhere to portions other than the non-adhesive layer 31 of the double-sided adhesive tape 27.
