TECHNICAL FIELD OF THE INVENTION
The present invention relates to a window glass in which a frame is integrally formed with glass, and more particularly to a window glass for a vehicle in which a mold for decoration or the like is fixed to the frame, and a method of manufacturing the same.
[0002]
[Prior art]
BACKGROUND ART In a window of a vehicle such as a train or an automobile, a glass plate is generally mounted on a metal body using a resin frame.
[0003]
Further, a resin or metal mold is attached to the frame for the purpose of decoration or the like, and an adhesive or a double-sided adhesive tape is used for fixing the mold.
[0004]
In recent years, a frame made of resin has been molded directly on a glass plate by extrusion molding or injection molding of a resin having fluidity, and a glass with a frame in which the frame and the glass plate are integrated has been used for a vehicle. Used as an assembly part.
[0005]
In some cases, a plate-shaped resin or metal mold is provided on the frame portion of the glass with the frame, and when the frame is injection-molded, the molding is performed simultaneously with the molding of the frame. A technique is known in which a mold is arranged in a cavity space of a mold to be used, and a glass plate, a frame, and a mold are integrated (Patent Document 1).
[0006]
If the mold moves in the mold during injection molding, the mold is not integrated at a predetermined position of the frame, resulting in a defective product. In order to avoid this, it is known to arrange a pin in a mold, fix the mold to the mold with the pin, and perform injection molding (Patent Documents 2 and 3).

[Problems to be solved by the invention]
When the mold is provided in the mold for injection molding of the frame and the mold is integrated simultaneously with the molding of the frame, the shape of the mold is set in order to install the mold in the mold. Is limited. In addition, when the mold is fixed with an adhesive after the window glass and the frame are fixed, the mold is displaced until the adhesive is solidified due to dimensional errors and twisting of the mold. As a result, a problem occurred in the shape.
[0009]
The present invention has been made to solve such a problem.
[0010]
[Means for Solving the Problems]
The glazed windowpane of the present invention comprises a resin frame integrally fixed to the periphery of the glazing, and a glazed windowpane having a mol fixed to the frame. Wherein the moles have hook-shaped ribs for fixing, and the hook-shaped ribs are inserted into through holes provided in the frame to fix the moles to the frame. It is a window glass with molding.
[0011]
Further, the above-mentioned method of manufacturing a window glass with a mold according to the present invention is characterized in that the frame is integrally formed with the window glass by injection molding so that a through hole is formed in the frame.
[0012]
Further, the above-described method for manufacturing a window glass with a mold is characterized in that a mold having hook-shaped ribs is manufactured by injection molding.

BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described with reference to the drawings.
[0014]
FIG. 1 is a side view of a window glass with a mold according to the present invention. The window glass with a mold of the present invention is obtained by integrating the frame 3 and the mold 2 into the window glass 1. In addition, 1 'shows the edge of a window glass.
[0015]
FIG. 2 is a sectional view taken along the line AA 'of FIG. 1, and FIG. 3 is a sectional view before the molding 2 and the frame 3 of FIG. FIG. 4 is a sectional view taken along the line BB 'of FIG. 1, and FIG. 5 is a sectional view before the molding 2 and the frame 3 of FIG.
[0016]
FIG. 6 is a partial view of the molding 2 seen from the bonding surface side, and FIG. 7 shows a portion of the frame 3 showing a through hole 10 provided in the frame 3.
[0017]
It is desirable that the frame 3 is integrally formed with the window glass 1. The frame 3 is preferably formed by injection molding, but may be extruded. Further, the frame 3 is not integrally formed with the window glass 1, but the window glass 1 is fitted into the frame 3 formed by extrusion molding, pultrusion molding, injection molding or the like. And may be integrated.
[0018]
The frame 3 can be formed using at least one resin such as a soft vinyl chloride resin, a urethane resin, a fluororesin, and a silicone resin.
[0019]
The frame 3 is provided with a through hole 10 for inserting a fixing rib provided on the mold 2. FIG. 6 shows a portion of the frame 3 near the cross section shown in FIG. 4, and the through-hole 10 is provided in the frame 3 where the window glass 1 is not provided.
[0020]
It is desirable that the through hole 10 is provided at an appropriate position according to the shape of the window glass and / or the frame body and / or the mold so as not to cause warpage or displacement of the mold.
[0021]
Further, it is desirable that the size and the cross-sectional shape of the through hole 10 match the shape of the rib inserted into the through hole 10.
[0022]
The through-holes 10 are desirably formed at the time of molding the frame 3. However, the through-holes 10 may be formed in the frame 3 using a drilling machine such as a drill.
[0023]
As the molding 2 used in the present invention, a molding made of resin or metal can be used, and the molding may be applied on the surface.
[0024]
The mall 2 is provided with a hook-like rib 4 having a hook-like tip. FIG. 7 is a perspective view showing a cross section of the molding 2 and the hook-shaped rib 4 manufactured in the embodiment of the present invention. The hook-shaped rib 4 is provided in accordance with the position of the through hole 10 shown in FIG.
[0025]
The hook-shaped rib 4 may be formed separately from the mold 2 and the hook-shaped rib 4 may be integrated with the mold 2 by adhesion or fusion. Preferably, a resin mold 2 or a metal mold 2 is set in a mold, and a hook-shaped rib 4 is injection-molded on the mold 2. As for the resin mold 2, it is desirable to form the mold 2 and the hook-shaped rib 4 by injection molding using one or more resins.
[0026]
Moreover, the surface may be painted or plated for decoration purposes. Further, a surface can be modified by inserting a film during injection molding.
[0027]
An adhesive 6 is applied to the mold 2, and the hook-shaped rib 4 is inserted into the through hole 10 to integrate the frame 3, the window glass 1 and the mold 2.
[0028]
Since the frame 3 and the mold 2 have an elongated shape along the periphery of the window glass 1, the cross-section of the hook-shaped rib 4 is also substantially rectangular, and the longitudinal direction of the approximately rectangle is parallel to the side of the window glass. It is preferable that a hook-shaped rib 4 is provided on the molding 2.
[0029]
FIG. 3 shows an example in which the adhesive 6 is applied to the mold 2, and FIG. 5 shows an example in which the adhesive 6 is applied to the frame 3. When applying an adhesive to the frame 3, it is desirable to provide a groove 11 for applying the adhesive to the frame 3, as shown in FIG. 6.
[0030]
【Example】
Example 1
FIG. 1 is a view showing a side surface of a window glass with a mold according to the present invention. The window glass 1 was molded with a flexible PVC resin frame 3 by injection molding. A substantially rectangular parallelepiped through-hole 10 shown in FIG. 6 was formed in the frame 3 at regular intervals.
[0031]
In this embodiment, the mold 2 is manufactured as a window frame cover for decoration. Mold 2 was injection molded using AES resin.
[0032]
As shown in FIGS. 2, 3, 4 and 5, the mold 2 has hooks for inserting into the through holes 10 shown in FIG. 7 in accordance with the through holes 10 formed in the frame 3. The ribs 4 were provided. Further, in order to close the gap between the mold 2 and the window glass 1, the mold 2 is provided with a closing member 8 made by extrusion molding.
[0033]
A primer was applied to the bonding surface of the frame 3 and the mold 2, and after the primer was dried, a urethane-based adhesive 6 was applied to the grooves 11 formed in the frame 3.
[0034]
In this embodiment, as shown in FIGS. 2 to 4, the cross-sectional shape is considerably different at the place of the molding. However, since the hook 6 is locked until the adhesive 6 is solidified, the molding is not performed. There was obtained a window glass with a good appearance without twisting or kinking of the metal.
[0035]
【The invention's effect】
The molded window glass of the present invention has almost no restriction on the shape by manufacturing the mold by injection molding, and the hook is locked to the frame by the hook-shaped rib until the adhesive is solidified. As a result, no twisting or the like occurs in the molding, and the mounting on the vehicle body is simplified.
