DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS.
This will be described below. The double glazing 7 has a spacer 5 arranged around the tempered glass 3 and the laminated glass 15 to form an air layer 4. The outside of the spacer 7 is systematically held by a glass frame 9 via a rubber 8. A flange formed on one end of the glass frame 9 is detachably attached to a main part of the vehicle body 10 with a bolt 12. These configurations are known.

The laminated glass 15 includes a resin glass 17 and
It is composed of a PC resin plate 14 on the outer surface side of the vehicle and a soft adhesive layer 16 connecting both. The area of the resin glass 17 is larger than the area of the PC resin plate 14, and there is no PC resin plate on the outer peripheral side of the resin glass 17 facing the outer surface side of the vehicle body. That is, the laminated resin glass 17 is finished to the inner shape dimension of the window frame 11, and the laminated glass 7 having a larger dimension than the inner dimension of the window frame 11, that is, the laminated glass 15 is previously bonded to the laminated glass 15 through the adhesive layer 16. There is something. The peripheral end surface of the PC resin plate 14 is formed with a chamfer 18 that is close to the thickness of the PC resin plate 14. The outer peripheral portion of the resin glass 17 is covered with the rubber 8 and the frame 9. 30 is an interior material.

A window frame 11 is formed on the vehicle body 10 in such a shape that the peripheral edge of the double-glazed glass 7, that is, the glass frame 9 is hidden. The thickness of the window frame 11 is such that the outer surface of the vehicle body and the outer surface of the PC resin plate 14 are flush with each other. A gap between the window frame 11 and the PC resin plate 14 is filled with a rubber-like caulking agent 6 such as thiochol or Si and fixed by adhesion.

According to this structure, unevenness can be prevented and noise can be reduced in the window glass portion. Moreover, since the mounting can be performed by the frame 9, the mounting can be easily performed with a simple configuration. Also,
The peripheral end surface of the PC resin plate 14 is as shown in the figure.
Since the chamfer 18 having a thickness close to the plate thickness is formed, the adhesion area of the caulking agent 6 which is filled and adhered and fixed in the gap with the window frame 11 can be increased and peeling can be prevented.

In the embodiment shown in FIG. 3, the outer dimensions (B) of the PC resin plate 14 are set to be larger than the inner dimensions (A) of the window frame 11 of the vehicle body 10. It is fixed to the chamfered end surface 19 of the window frame 11 via the. That is, even if the caulking agent 6 is peeled off or destroyed due to deterioration of the caulking agent 6 or another external accident in the unlikely event of an accident, the adhesive force of the adhesive layer 16 can guarantee safety. Even if destruction such as peeling is performed, PC
The resin plate 14 is used for the vehicle body 1 unless the double glazing 7 is destroyed.
The configuration is such that there is no peeling and detachment outside 0. Further, the excellent effect of this constitution is that the outer surface area of the caulking agent 6 can be reduced, and it has an effect as a structure for protecting against external stress and also as a visual smoothness in design.

In the embodiment shown in FIG. 4, the outer PC resin plate 14 constituting the laminated resin glass 17 of the multi-layer glass 7 is attached to the window frame 1.
The size is set to be larger than that of No. 1 and is bonded and fixed to the fitting portion 22 formed on the window frame side of the vehicle body 10. At this time, the adhesive layer 16 may be processed on the entire inner surface of the PC resin plate 14 or may be set within the shape dimension of the laminating glass 15. The peripheral edge surface of the PC resin plate 14 and the PC resin plate 1
The gap portion of the inner end surface of the fitting portion 22 having the same drop step as that of No. 4 is filled and bonded and fixed by the caulking agent 6.

The detachable mounting and fixing of the vehicle body 10 and the double glazing 7 while maintaining the mechanical strength is carried out by fixing and mounting the glass frame 9 on the peripheral end face of the main body of the double glazing 7 through the rubber 8. It is fitted and mounted on the inner end surface of the frame 11 with a proper gap, and is completely fixed by the bolt 12 or the like at the window frame flange 21 portion. The glass frame 9, the window frame flange 21, and the bolt 12 are covered by the interior 13 mounted inside the vehicle.

The purpose of this construction is to mount and assemble the window glass from the outside of the vehicle rather than the general inside of the vehicle. This means that after assembling and installing various equipment inside the vehicle, if only the design member of the interior 13 is supported, the window glass can be the final step of the assembling, and in the unlikely event of damage to the window glass, replacement is required. If it is forced to leave, it will not be the important work of incorporating it into the car as before, and it will be possible to easily deal with it.

Further, when a high-speed vehicle rushes into a tunnel or the like at high speed, it receives external air pressure. As a countermeasure against that, the PC resin plate 14 forming the outer surface of the double glazing 7 is large. This is also an excellent configuration that contributes to safety.

The embodiment of FIG. 5 is a case where the PC resin plate 14 is enlarged to the extent that the fitting portion 22 described in FIG. 4 disappears.
At the center of the pillar portion 23 between the two windows of the vehicle, the PC resin plate 14 symmetrically extended from the two windows is brought into contact. The caulking agent 6 is provided in the gap portion of the abutting end face together with the groove 24 in which the central vertical groove of the pillar portion 23 is formed.
It is filled and fixed by adhesion.

The fact that the above figure is a top view of the cross section of two windows means that the transparent members constituting the windows are connected to each other to form a continuous window. That is, the transparent member of the same quality enables a belt-shaped continuous window structure that covers the entire window frame of the vehicle.

At the asymmetrical position (A) shown by the dotted line in the figure, only the PC resin plate 14 on the right side in the figure is stretched to cover the left window frame 11 or the pillar portion 23 as a whole. Is. As a matter of course, the caulking agent 6 is filled, adhered and fixed to the portion where the end faces of the PC resin plate 14 are brought into contact with each other. That is, the purpose of the asymmetrical structure is that the vehicle body can be incorporated both outside and inside the vehicle.

[0018]

According to the present invention, unevenness can be prevented and noise can be reduced in the window glass portion. Further, since the mounting can be performed by the frame, it can be easily performed with a simple configuration.
