Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a curtain device for a vehicle window glass.

[0002]

2. Description of the Related Art Some automobiles and railway vehicles have a window glass provided with a curtain, and this curtain is used for the purpose of anti-glare and for suppressing the rise in indoor temperature. As an example of this curtain, Japanese Utility Model Publication No. 4-27687, "A Curtain Device for Curved Window Glass for Vehicles" is known.

According to FIG. 2 of the publication, the curtain device is such that the curtain groove island 6 is inserted into the interior of the vehicle from the curved window glass 7 by a fixed amount and assembled to the vehicle body 14, and the lower horizontal bar 5 is attached to the curtain groove island 6. In this device, the lower horizontal bar 5 is attached to the lower end of the curtain 1, and the upper end of the curtain is attached to the curtain winding drum 2. When the curtain 1 is opened by raising the lower horizontal bar 5 along the curtain groove island 6, the curtain 1 is wound on the curtain winding drum 2, and the lower horizontal bar 5 is moved along the curtain groove island 6. When the curtain 1 is lowered and closed, the curtain 1 is rewound from the curtain winding drum 2.

[0004]

SUMMARY OF THE INVENTION
As described above, since the curtain groove island 6 is arranged at a position where a certain amount of the curtain groove island 6 enters the indoor side from the curved window glass 7, the indoor space is narrowed. In addition, since the curtain groove island 6 is mounted on the vehicle body 14, the configuration of the vehicle body 14 is complicated, and the design time of the vehicle body structure and the mounting time on the vehicle body assembly line become longer.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a technique that does not make the indoor space narrow and shortens an assembling time in a vehicle body assembly line.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a first aspect of the present invention is a vehicle window glass, a guide rail directly attached to an inner surface of the window glass, and a guide rail extending along the guide rail. A curtain device for a vehicle window glass, comprising a curtain that opens and closes.

Since the guide rail is directly attached to the inner surface of the window glass of the vehicle, the guide rail and other curtain devices can be brought closer to the window glass. Therefore, the indoor space can be expanded more than before. Further, the assembling work of the curtain device can be performed on, for example, a window glass manufacturing line outside the vehicle assembly line. In the vehicle assembly line, it is only necessary to attach the window glass with the curtain device to the vehicle body. Therefore, it is possible to shorten the operation time in the vehicle assembly line and to omit the operation of mounting the guide rail in the vehicle body.

[0008] By integrating the window glass and the guide rail, rigidity as an integral object is increased. Therefore, as compared with a single unit, the thickness of the window glass can be reduced and the guide rail can be simplified, so that the material of the window glass and the guide rail can be saved and the weight can be reduced. In addition, since the guide rail is directly and integrally attached to the inner surface of the window glass of the vehicle, the rigidity of the window glass increases because the guide rail also serves as a reinforcing material for the window glass. Therefore, a reinforcing material for the window glass can be eliminated. This role as a stiffener is particularly important in glass that is subjected to relatively high wind pressures, such as roof glass for automobiles.

A second aspect of the present invention is characterized in that the window glass is a curved glass.

The curtain can be opened and closed along the curved glass by attaching the guide rail to the window glass in a curved shape.

The third aspect of the present invention is characterized in that a portion of the window glass on which the guide rail is mounted is masked.

[0012] By masking the window glass portion on which the guide rail is mounted, the guide rail can be hidden by the masking. Therefore, the guide rail can be made invisible from the outside of the vehicle, and the deterioration of the adhesive for attaching the guide rail to the window glass can be prevented. Further, since the masking surface is rougher than the window glass surface, the adhesiveness of the adhesive can be increased and the guide rail can be firmly bonded.

According to a fourth aspect of the present invention, the distance between the inner surface of the window glass and the inner surface of the curtain is set in a range of 3 mm to 20 mm.

Since the curtain was brought very close to the window glass,
A sufficient passenger compartment volume can be ensured, and there is no risk of peeping through a gap with the curtain, so that privacy can be maintained well.

According to the present invention, the following effects are exhibited by the above configuration. According to the first aspect, since the guide rail is directly attached to the inner surface of the window glass of the vehicle, the guide rail and other curtain devices can be brought closer to the window glass. Therefore, the indoor space can be expanded more than before. Further, the assembling work of the curtain device can be performed on, for example, a window glass manufacturing line outside the vehicle assembly line. In the vehicle assembly line, it is only necessary to attach the window glass with the curtain device to the vehicle body. Therefore, it is possible to shorten the operation time in the vehicle assembly line and to omit the operation of mounting the guide rail in the vehicle body.

By integrating the window glass and the guide rail, the rigidity as an integral object is increased. Therefore, as compared with a single unit, the thickness of the window glass can be reduced and the guide rail can be simplified, so that the material of the window glass and the guide rail can be saved and the weight can be reduced. In addition, since the guide rail is directly and integrally attached to the inner surface of the window glass of the vehicle, the rigidity of the window glass increases because the guide rail also serves as a reinforcing material for the window glass. Therefore, a reinforcing material for the window glass can be eliminated. This role as a stiffener is particularly important in glass that is subjected to relatively high wind pressures, such as roof glass for automobiles.

According to the second aspect, the curtain can be opened and closed along the curved glass by attaching the guide rail to the window glass in a curved shape.

According to a third aspect of the present invention, the guide rail can be hidden by masking by masking the portion of the window glass on which the guide rail is mounted. Therefore, the guide rail can be made invisible from the outside of the vehicle, and the deterioration of the adhesive for attaching the guide rail to the window glass can be prevented. Further, since the masking surface is rougher than the window glass surface, the adhesiveness of the adhesive can be increased and the guide rail can be firmly bonded.

According to the fourth aspect, since the curtain is brought very close to the window glass, a sufficient volume in the vehicle compartment can be ensured, and there is no possibility of peeping through a gap between the curtain and the privacy, so that good privacy can be maintained.
