Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device in which a display member having a liquid crystal panel, an LED display panel, an electroluminescence display panel or the like as a display surface is swingable with respect to a support member.

[0002]

2. Description of the Related Art FIG. 12 is a perspective view showing an in-vehicle display device installed on a console panel of an automobile, and FIG.
It is a partial expansion perspective view which expands and shows a part of display device which was the structure which can rotate only a display part. A display device 1 shown in FIG. 12 includes a case 3 fixed to a central portion of a console panel 2 of an automobile, guide mechanisms 4 and 4 provided on both sides of the case 3, and A1 by guide mechanisms 4 and 4.
The support member 5 is provided so as to be movable in the −A2 direction, and the display member 6 is supported on the support member 5 so as to stand upright in the α direction and be swingable. The display member 6 includes, for example, a liquid crystal television panel as the display surface 6a. When not in use, the display member 6 is in the horizontal posture shown by (B), the support member 5 moves in the A2 direction, and the display member 6 is housed in the case 3. The front surface of the device is closed by the door member 7.
In use, when the door member 7 is opened and the display member 6 in the horizontal posture projects in the A1 direction together with the support member 5, and the support member 5 projects outside the case 3, the display member 6 rotates in the α direction ( It becomes the standing posture shown in b).

[0003]

Since the display device 1 is presumed to be attached to the console panel 2 like a car radio as shown in FIG. 12, for example, the standing posture shown in (a) at the time of use. When
The display surface 6a of the display member 6 is directed rearward from between the driver's seat and the passenger seat. Therefore, the display surface 6a is difficult to see from the driver's seat or the passenger seat. Display surface 6 in particular
When a is a liquid crystal panel, since the viewing angle is narrow, the image on the display surface 6a cannot be clearly seen from the driver's seat or the passenger's seat.

Therefore, a display device shown in FIG. 13 can be considered. In this display device, a support member 5 is supported by a guide mechanism 11 that moves from the case 3 in the A1-A2 direction, and a frame 9 is supported by the support member 5 so as to be rotatable in the α direction. Similar to that shown in FIG.
When the support member 5 moves in the A1 direction during use, the frame 9 turns in the A1 direction and assumes a standing posture. The frame 9 is provided with a display member 10 that rotates in the β direction about one axis O. When the frame 9 is in a standing posture, the display member 10 is rotated in the β direction to display the display surface. 10a can be turned toward the driver's seat or toward the passenger seat, for example.

However, in the above structure, the display member 1
0 rotates about one axis O, and since this axis O is provided at the center of the width direction of the display member 10, when the display member 10 is rotated, the corner portion at the rear end is rotated. 10b will protrude greatly to the rear. Since a car radio and other devices 8 are mounted on the console panel 2, if the corners 10b of the display member 10 project rearward, they will hit the operation buttons of these devices 8 and the display member 10 will be in the β direction. It becomes impossible to rotate at a large angle. Further, for example, when the display member 10 is rotated in one direction as shown in FIG. 13 and the display surface 10a is viewed from the diagonal direction indicated by the arrow S, the right end portion of the display surface 10a in the drawing largely moves backward, There is a drawback that it cannot be seen because it is hidden behind the corner 9a of the frame 9.

The present invention is to solve the above-mentioned conventional problems. When the display member is swung with respect to the support member, the display surface can be easily seen, and further the swinging of the display member causes the display member to move backward, for example. It is an object of the present invention to provide a display device that does not project.

[0007]

According to another aspect of the present invention, there is provided a display device having a support member and a display member swingably supported by the support member. The swing fulcrum is different when swinging in the direction and when swinging in the opposite direction.

Further, the display member is provided with first and second shaft members spaced apart in a direction parallel to the display surface, and the support member is guided to guide the respective shaft members in a direction intersecting the display surface. And a drive member that reciprocates with respect to the support member. When the drive member moves in one direction, the first shaft member is constrained and the second shaft member is attached to the drive member. Move it along the guide part in the direction to project the display surface,
A drive guide portion is provided for restraining the second shaft member and moving the first shaft member in the direction in which the display surface is projected along the guide portion when moving in the other direction.

Further, in each of the above means, it is possible to further support the display member with respect to the main body which supports the display member so as to be swingable in a direction intersecting the swing direction of the display member.

[0010]

According to the first means, when the display member swings on the support member, the swing fulcrum changes according to the swinging direction. Therefore, no matter which direction the rocking is performed, the display surface of the display member can be moved so as to protrude forward, for example, and the display surface can be easily viewed from an oblique direction. Further, for example, it is possible to prevent the display member from significantly protruding rearward.

The second means relates to a mechanism for changing the swing fulcrum. In this means, when the movably provided drive member is moved in one direction or the opposite direction,
The drive member guides one of the pair of shaft members provided on the display member. Then, one shaft member serves as a fulcrum and the other shaft member moves toward the front of the display surface, and the display member is oriented in the oblique lateral direction in a state where it is easy to see.

Further, in each of the above means, the supporting member that swingably supports the display member can be further swung with respect to the main body in a direction intersecting the swinging direction of the display member. It is also possible to orient the display surface of the display member three-dimensionally in all directions.
