Embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 and 2 show a first embodiment of the present invention. A car or a railway car will be described as an example of a vehicle. As shown in FIG.
And a window 3 is provided above the door 2.
In such a vehicle 1, as shown in FIG.
It is preferable to provide this device. Lower frame 4 of the window 3
D has guide rails 5 and 6 opened to the outside and inside, respectively, and the outside rail 5 is formed so that a transparent glass 7 serving as a transparent plate for opening and closing the window 3 can be moved up and down.
The inner rail 6 is formed so that a colored glass 8 serving as an opening and closing plate for opening and closing the window 3 can be moved up and down in a state substantially parallel to the transparent glass 7, and the colored glass 8 is 3 mm in bronze or green. A glass material having a predetermined light transmissivity and a higher light blocking ratio than the transparent glass 7 is used, and plastic materials other than glass can also be used. The colored glass 8 has a thickness of about 3 mm. The rails 5 and 6 are provided at predetermined intervals so as to form a gap S between the glasses 7 and 8. When the two glasses 7 and 8 are raised, the upper end thereof is raised to the upper frame portion 4U of the window 3, and the window 3 is closed. Inside the door 2, an automatic opening / closing means 9 for raising and lowering the transparent glass 7 is provided.
The automatic opening / closing means 9 and 10 have a known elevating mechanism (not shown) that combines a rank and a pinion. The transparent glass 7 and the colored glass 8 are opened and closed by lifting and lowering with the power of 12. The automatic opening / closing means 9 and 10 are electrically connected to an operation unit 13 provided in the vehicle 1, and an operation switch provided on the operation unit 13 is provided.
It opens and closes independently by 14 and 15, respectively. The operation unit 13 is provided with a simultaneous operation switch 16, and the simultaneous operation switch 16 causes the two glasses 7, 8 to move up and down at the same time.

The operation of the operation switch 15 raises the colored glass 8 and closes the window 3 to prevent external light from entering. Further, when the two glasses 7 and 8 are closed, a gap S is formed between the two, and the gap S becomes an air layer, so that the heat insulating property of the window 3 is improved and an anti-fog effect is obtained.

As described above, in this embodiment, the opening / closing plate having a higher light blocking ratio than the transparent plate 7 is provided inside the transparent glass 7 serving as the transparent plate provided in the window 3 of the vehicle 1. The glass 8 is provided, and the colored glass 8 is configured to open and close substantially in parallel with the transparent glass 7. Therefore, by closing the colored glass 8, it is possible to control the penetration of external light. Further, since the colored glass 8 moves substantially in parallel with the transparent glass 7, the colored glass 8 can be attached without taking up a relatively large space.

In this embodiment, as described above, claim 2
In response to the above, the transparent plate is a transparent glass 7, the opening / closing plate is a colored glass 8, an automatic opening / closing means 10 for raising and lowering the colored glass 8 to open and close, and an operation unit for operating the automatic opening / closing means 10.
Since the colored glass 8 is moved up and down by the operation of the operation unit 15, the window 3 can be automatically opened and closed.

Further, as an effect of the embodiment, since a gap S is provided between the two glasses 7 and 8, by closing both glasses 7 and 8, an air layer is formed therebetween, thereby forming the window 3. The heat insulating property is improved, and an anti-fogging effect can be obtained. Also, since the simultaneous operation switch 16 is provided,
Both glasses 7, 8 can be moved up and down by one switch operation.

FIGS. 3 and 4 show a second embodiment of the present invention, in which the same parts as those in the first embodiment are denoted by the same reference numerals, and the detailed description thereof will be omitted. The operation unit 13 is provided with a control unit 17 composed of a computer or the like. The control unit 17 regulates the colored glass 8 from rising above the transparent glass 7 position, and controls the colored glass 8 from the same height position or the transparent glass 7. Is controlled so that when both glasses 7 and 8 have the same height, both glasses 7 and 8 are simultaneously lowered.

Therefore, as shown in FIG. 4A, when the transparent glass 7 is in the half open / close position and the colored glass 8 is raised by operating the operation switch 15, the same position as the transparent glass 7 indicated by the dashed line is obtained. Stop at, no more colored glass 8
Does not rise, and when the transparent glass 7 is in the fully open position, the colored glass 8 does not rise even if the operation switch 15 is operated. Further, when the transparent switch 7 is lowered by operating the operation switch 14 at the position indicated by the solid line in FIG. 4A, the position of the two glasses 7, 8 shown in FIG. , 8 descend simultaneously. FIG.
At the position indicated by the solid line (A), the operation switch 15 can be operated to lower the colored glass 8.

As described above, in this embodiment, even when the control switch 17 is operated by the control unit 17, the colored glass 8 as the inner opening / closing plate is moved beyond the height position of the transparent glass 7 as the outer transparent plate. Controlled so as not to rise,
The control unit 17 operates the operation switch 14 to operate the transparent glass 7.
Is controlled so that both glasses 7, 8 are lowered from the position where both glasses 7, 8 are aligned, so that only colored glass 8 does not close, and
Can be used, the strength of which is lower than that of the transparent glass 7 directly exposed to the outside. Opening the transparent glass 7 usually requires opening the window 3. Therefore, even if the colored glass 8 is raised, the window 3 can be closed only by operating the operation switch 14.

FIG. 5 shows a third embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. A case is shown in which the outer transparent glass 7 is fixed to the window 3 of the vehicle 1A of FIG. In this case, the operation switch 15 is preferably provided near the window 3 of the vehicle or near the armrest of the seat on the side of the window 3.

Also in this example, the transparent plate is the transparent glass 7, the opening / closing plate is the colored glass 8, and the automatic opening / closing means 10 for raising and lowering the colored glass 8 to open and close the same is operated. Since the operation unit 15 is provided in the railway vehicle 1A, the colored glass 8 can be moved up and down by the operation of the operation unit 15 to automatically open and close the window 3, thereby opening and closing a conventional curtain. The operation can be easily performed without any trouble.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example, the transparent plate is not limited to glass, but may be transparent plastic. Further, the present invention can be used for various vehicles, and the automatic opening / closing means can use various lifting mechanisms. Furthermore, in the embodiment, the opening / closing plate is raised to close the window and lowered to open the window. However, in the case of a railway vehicle, the opening / closing direction may be reversed upside down or left / right. Also,
A so-called bronze glass or the like may be used as the colored glass.
