Abstract

PROBLEM TO BE SOLVED: To provide light shielding covers for an on-vehicle monitor where light shielding is favorable in every environment and to improve the usability of the light shielding covers for the onvehicle monitor. SOLUTION: Any or all of light shielding covers (flaps) 13 are properly rocked to cut off sunlight in accordance with the incident angle of sunlight on a monitor screen 12. The covers 13 cut off sunlight made incident on the screen 12. Sunlight is cut off by properly moving the flaps 13 even when the position of the screen 12 is changed by vehicle driving. Therefore, the screen 12 can clearly be watched. The covers 13 are integrally formed in a U-shaped form, and also can externally interfit over the a monitor body 11. The screen 12 is shielded from sunlight by holding a part of the cover 13 and drawing it out to an appropriate position in accordance with the incident angle of sunlight.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light shielding cover of a monitor mounted on a vehicle, for example, a light shielding cover for shielding a screen of a monitor mounted on a civil engineering vehicle from light.

[0002]

2. Description of the Related Art In recent years, in order to cover a blind spot from a driver's seat, a large-sized vehicle for transportation, construction and civil engineering, etc., has been increasingly equipped with a CCD camera at the site. This blind spot is imaged by a CCD camera, and an image is displayed on a monitor. In this case, the monitor is fixed and mounted at a position where the operator / driver can visually recognize the monitor from, for example, a driver's seat. Therefore, the driver operates and works while watching the monitor.

[0003]

However, in such a monitor mounted on a vehicle, the screen is fixed at a position in the vehicle such that the driver / operator can easily recognize the screen. Depending on the place of work or driving,
Sometimes it was difficult to see the monitor screen. This was due to the influence of sunlight entering obliquely.

The inventor of the present invention, as a result of diligent research, has found that light can be shielded by attaching a light-shielding cover to a monitor and visibility can be improved, and the present invention has been completed. In addition, the inventors have found that the usability in a driving / working environment can be enhanced by allowing the size or the mounting position of the light-shielding cover to be adjusted with one touch, and have completed the present invention.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a light-shielding cover for a vehicle-mounted monitor having good light-shielding properties in different environments. Another object of the present invention is to improve the usability of a light shielding cover of a monitor mounted on a vehicle.

[0006]

According to a first aspect of the present invention, there is provided a light-shielding cover for blocking light rays incident on a screen of a monitor mounted on a vehicle, and the light-shielding cover is capable of moving forward and backward with respect to the screen. This is a light shielding cover of a vehicle mounted monitor in which the light shielding cover is attached to the monitor body.

According to a second aspect of the present invention, there is provided a light-shielding cover for blocking sunlight incident on a screen of a monitor mounted on a vehicle, wherein a flap is swingably supported on a side surface and / or an upper surface of a monitor body. And a light-shielding cover of a vehicle-mounted monitor for shading the monitor screen by swinging these flaps.

[0008]

According to the first aspect of the invention, the light-shielding cover is pulled out from the rear of the monitor main body to the front in accordance with the direction of the light beam. As a result, light rays incident on the monitor screen are blocked by the light-shielding cover. Therefore, the worker / driver can surely visually recognize the monitor screen.

According to the second aspect of the present invention, the sunlight is blocked by swinging the flap in accordance with the direction of the sunlight. Therefore, the monitor screen does not become difficult to see due to the reflection of sunlight.
If the direction of sunlight changes with respect to the vehicle during the work, the flaps are appropriately swung to block the flaps.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described more specifically with reference to the following examples. FIG. 1 is a perspective view showing a light shielding cover according to an embodiment of the present invention. As shown in this figure, a monitor 11 composed of a substantially rectangular parallelepiped is fixed, for example, at a position near the driver's seat of the vehicle, for example, on a dash panel. In this case, the screen 12 of the monitor 11 is disposed facing the driver's seat. The light-shielding cover 13 is made of three plate-like materials (flaps) each formed of a material that blocks sunlight.
It is formed with. These plate-like members 13 are swingably attached to both sides of the monitor main body 11 and the screen side of the upper surface, and the monitor screen is shielded from sunlight by swinging these flaps 13. I do. That is,
Each flap 13 is formed in a size that can block external light rays to the monitor screen 12.

Therefore, the light-shielding cover 13 can block the sunlight incident on the monitor screen 12 by appropriately swinging the three plate-shaped members according to the incident angle of the sunlight. Further, it is preferable that an appropriate frictional force be applied to the swing fulcrum (such as a pin) so that the plate-shaped body 13 is located at the swung position. Alternatively, a stopper may be provided at a fulcrum of the plate-like body 13 to position these plate-like body 13 at an appropriate swing position (angular position). The screen of the monitor 11 may be any of a cathode ray tube, a liquid crystal, and the like.
Further, the material of the flap 13 may be any material as long as it has a predetermined strength and can shield light, and is preferably made of plastic, paper, or the like.
Further, although not shown, the monitor 11 is connected to a CCD camera or the like. When the monitor 11 is far from the driver's seat and is hard to reach, the light-blocking cover may be configured to be electrically operated, and the flap may be opened and closed by remote control operation.

FIG. 2 shows another embodiment of the light shielding cover according to the present invention. In this embodiment, the light-shielding cover 21 is integrally formed in a U-shape, fitted into the monitor main body 11 from above, and is slidable in the front-rear direction. The light-shielding cover 21 has opposing side pieces and an upper piece, and these side pieces are slidably supported on the side surface of the monitor main body 11 and the upper piece is slidably supported on the upper surface thereof. Therefore, the light-shielding cover 21 can be attached to the monitor screen 12 with one touch.
In the front-rear direction.

In this embodiment, the light-shielding cover 21 can be pulled out to an appropriate front position by grasping a part of the light-shielding cover 21 according to the angle of sunlight and pulling it out. Can be shaded. When the angle position of sunlight changes due to driving of the vehicle, the light-shielding cover 21 is pushed in and out each time, so that more appropriate light-shielding can be performed. Note that a handle or the like may be fixed to a part of the upper piece of the gate-shaped light shielding cover 21.

[0014]

According to the present invention, sunlight (external light)
The position of the light-shielding cover can be moved with one touch each time the angle of the on-vehicle monitor changes with respect to, and the monitor can be easily shielded from light.
