Abstract

PURPOSE:To provide an on-vehicle projection type television set which does not prevent a driver from making rear side confirmation. CONSTITUTION:A folding screen 1 is maintained in the condition laid down to a ceiling 4 side as shown in a dashed line, so as not to project downward from the ceiling 4, when it is not used. On the other hand, when it is used, the folding screen 1 is maintained in a specific erecting condition as shown in the solid line. By this erecting condition, the folding screen 1 forms a sheet of screen when a passenger 6 or the like at the rear seat 3 observes, and at the same time, a projection type TV main body 2 can project the image correctly on the folding screen 1. Furthermore, this erecting condition makes a driver 5 see that individual screen piece sheets 1a are arranged systematically in the up and down direction placing specific intervals by forming a surface almost parallel to the ceiling 4, when he observes the rear side through a room mirror 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted projection television apparatus, and more particularly to a vehicle-mounted projection television apparatus for passengers and the like in the back seat of an automobile to view images.

[0002]

2. Description of the Related Art Conventionally, a television device for passengers and the like in the back seat of an automobile to view an image has been mounted on the ceiling in the passenger compartment.

[0003]

Therefore, even when the television device is not used, it is in a state of protruding downward from the ceiling, and there is a problem that the aesthetics of the passenger compartment is easily spoiled.

In consideration of the above problems, it is possible to mount a projection type television device having a thin screen that can be stored in an automobile. However, since the screen is kept in an expanded state in the vehicle compartment during use, the screen may hinder the driver's rearward confirmation.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle-mounted projection type television device which does not hinder the driver's backward confirmation in view of the above points.

[0006]

In order to solve such a problem, a vehicle-mounted projection type television apparatus according to the present invention is provided with a foldable screen mounted on a ceiling in a vehicle compartment, and the foldable screen. The tiltable screen comprises a plurality of screen piece thin plates arranged at intervals from each other, and each of the screen piece thin plates is used. At this time, a surface that is substantially parallel to the ceiling is formed.

[0007]

When the foldable screen is not used, it is laid down toward the ceiling. For this reason, the folding screen does not hinder the driver's rearward confirmation and does not impair the appearance of the vehicle interior.

On the other hand, in use, the foldable screen is used upright, and in this upright state, the individual screen piece thin plates form a surface substantially parallel to the ceiling. Therefore, the driver can see the rear through the space formed by the screen piece thin plates adjacent to each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The on-vehicle projection television apparatus 10 according to this embodiment comprises a retractable screen 1 and a projection television main body 2.

The foldable screen 1 is a rear seat 3 in the passenger compartment.
It is attached to the ceiling 4 at the upper front and in the center of the left-right direction by an appropriate attachment member. Retractable screen 1
Is composed of a plurality of screen piece thin plates 1a arranged at intervals from each other and supported by two transparent plates 1b and the like.

When the foldable screen 1 is not used, the foldable screen 1 is held in a state of being tilted to the ceiling 4 side as shown by the alternate long and short dash line in FIG. 1 so as not to project downward from the ceiling 4. Therefore, the folding screen 1 does not hinder the rearward confirmation of the driver 5 and also does not impair the appearance of the vehicle interior.

On the other hand, during use, the retractable screen 1 is held in a predetermined standing state as shown by the solid line in FIG. 1 and FIG. This standing state appears to the passengers 6 and the like in the rear seat 3 as if the foldable screen 1 forms one screen, and at the same time the projection television main body 2 is correctly displayed on the foldable screen 1. In a standing state in which the screen 5 can be projected, and when the rear side is viewed from the driver 5 through the rearview mirror 7, the individual screen piece thin plates 1a form a plane substantially parallel to the ceiling 4 and move up and down. The standing state is such that they appear to be lined up at regular intervals in a certain direction. Therefore, when the retractable screen 1 is in the standing state as described above, the passengers 6 and the like in the rear seat 3 can view the image, while the driver 5 is normally adjacent to each other via the rearview mirror 7. Screen piece thin plate 1
The rear can be confirmed through the space formed by a.

The projection-type television main body 2 is installed at the center in the left-right direction on the package tray trim panel 8 behind the rear seat 3 so that an image can be projected obliquely from below the retractable screen 1. There is. The projection type television main body 2 can be housed in the package tray trim panel 8 when not in use.

As described above, the retractable screen 1
When not in use, it is tilted down to the ceiling 4 side and held. Therefore, the folding screen 1 does not hinder the rearward confirmation of the driver 5 and also does not impair the appearance of the vehicle interior. On the other hand, during use, the foldable screen 1 is used while being held in a predetermined upright state, and in this upright state, the individual screen piece thin plates 1a form a plane substantially parallel to the ceiling 4. Therefore, the driver 5 can normally see the rear through the space formed by the screen piece thin plates 1a adjacent to each other via the room mirror 7.

In the above embodiment, the foldable screen 1 has the fixed screen piece thin plate 1a, but it has the movable screen piece thin plate 1a whose angle can be arbitrarily adjusted. The formula screen 1 may be used. Further, the two transparent plates 1b for supporting the screen piece thin plate 1a can be omitted by using an alternative means for supporting the screen piece thin plate 1a.
