Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a light-shielding hood device for a liquid crystal television receiver.

BACKGROUND OF THE INVENTION In recent years, liquid crystal television receivers have attracted attention as pocket televisions that emphasize portability because they are small and lightweight.

Conventional LCD television receivers have a rotatable liquid crystal panel attached to the front of the receiver body.For example, when used outdoors, external light can be removed from the back of the liquid crystal panel. The TV image on the LCD panel was brightened to make it easier to watch. On the other hand, when used outdoors, ambient light is reflected on the TV screen in the LCD panel section, making the TV screen itself difficult to see. It is known to mount a light-shielding hood device in which a hood plate is fixedly provided on at least three upper sides in a substantially U-shape.

Problems to be Solved by the Invention However, in the conventional light-shielding hood device, the hood plate is fixedly provided in a substantially U-shape. The liquid crystal television receiver itself increases in size when the hood device is attached, which has the drawback of hindering portability as a pocket television. Moreover, even though the conventional light-shielding hood device is detachable from the liquid crystal panel of the LCD television receiver body, the light-shielding hood device itself is large in size because the hood is fixedly disposed. However, there was also a problem in the portability of the light-shielding hood device itself.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome these conventional drawbacks and to provide a light-shielding hood device for a liquid crystal television receiver that is convenient to carry.

A third hood plate is rotatably supported at the upper end of the opening of the case body and is always biased by a spring in the opening direction, and the third hood plate is configured to move the first and second hood plates in the closing direction. The spring force biasing the third hood plate is set to be larger than the spring force biasing the third hood plate in the opening direction, and when the first, second, and third hood plates are opened, the third hood plate
A bending piece is provided at the upper end of the first and second hood plates so as to be able to engage with both ends of the hood plate, and when the first, second and third hood plates are closed, the folding pieces are provided. The present invention is characterized in that the curved piece is configured to fit into a gap between the axis supporting the third hood plate and the case body.

Effect The present invention, with the above-described configuration, applies an external force to the third hood plate in the direction of the spring biasing force and pulls up the third hood plate. The hood plate is opened while contacting both ends of the third hood plate against the spring biasing force, and when the first, second, and third hood plates are opened, the first, second, and third hood plates are opened. The bent piece provided at the upper end of the second hood plate engages both ends of the first hood plate, and the spring biasing force that closes the first and second hood plates opens the third hood plate. Since the third hood plate is pulled up and opposes the spring biasing force of the first and second hood plates, the open state of the first, second, and third hood plates is maintained. can do. On the other hand, when the first, second, and third hood plates are opened, by pulling down the third hood plate against the spring biasing force, the first, second, and third hood plates are opened by the spring biasing force. This means that the third hood plate is closed while being in contact with both ends of the third hood plate, and when the first, second, and third hood plates are closed, the first and second hood plates are folded. The curved piece enters the gap between the center of rotation of the third hood plate and the case body, and the spring biasing force that closes the first and second hood plates is greater than the spring biasing force that opens the third hood plate. Therefore, the above first, second and third
The closed state of the hood plate can be maintained.
As a result, it is possible to easily open and close the hood plate, which is rotatably disposed on the case body, and is configured to be detachable from the liquid crystal panel of the liquid crystal television receiver body. This means that portability can be improved.
