ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a display apparatus to be mounted on a moving body such as an automobile.
2. Description of the Related Art
Heretofore, a display unit such as a television set provided with a liquid crystal display panel is often accommodated in a vehicle as the moving body. This display unit displays information such as images received by the television set.
As an example of the display apparatus provided with the above described display unit
101
, there has been proposed a display apparatus
102
attached to a ceiling
103
of an automobile as the moving body, as shown in FIG.
8
. The display apparatus
102
illustrated in
FIG. 8
includes the display unit
101
which can display the above mentioned information and adapted to be fitted to the ceiling
103
of a passengers' room of the automobile at a wall face
103
a
facing with the passengers' room.
The above described display unit
101
includes a display panel
104
which can display the above mentioned information and a casing
105
for containing this display panel
104
. The casing
105
is formed in a rectangular shape. The display unit
101
is fitted to the wall face
103
a
so as to rotate around a rotation axis
106
.
The rotation axis
106
is arranged along both the wall face
103
a
and a side of the casing
105
. The rotation axis
106
is arranged on an/upper part of the display unit
101
in a lateral direction of the display unit
101
.
According to the above described structure, the display apparatus
102
can provide the passengers with the information by rotating the display unit
101
around the rotation axis
106
.
The above mentioned automobile as the moving body accommodates a plurality of seats on which the passengers can be seated. In the above described display apparatus
102
, the display unit
101
for displaying the information is provided so as to rotate around only one rotation axis
106
, and therefore, visibility of the display panel
104
varies according to positions of the seats.
For this reason, according to the positions of the seats, it has been difficult to visually observe the information displayed on the display panel
104
with reliability. It can be hardly said that the information can be surely supplied to all the passengers seated on a plurality of the seats.
In view of the above described drawback, it is an object of the present invention to provide a display apparatus which can avoid different visibility according to positions of the seats, when the display apparatus is provided in a moving body accommodating a plurality of the seats, and can reliably supply information to passengers seated on all the seats.
SUMMARY OF THE INVENTION
In order to solve the above described problem and attain the object, there is provided a display apparatus, according to a first aspect of the present invention, which comprises a rotary portion rotatably provided on a ceiling of a moving body, an arm portion supported by means of the rotary portion, and a display portion supported by means of the arm portion.
According to a second aspect of the invention, the arm portion is rotatably supported by means of the rotary portion.
According to a third aspect of the invention, the rotary portion is provided so as to rotate around a first rotation axis which extends in a direction intersecting the ceiling, and the arm portion is supported by means of the rotary portion so as to rotate around a second rotation axis which intersects the first rotation axis.
According to a fourth aspect of the invention, the display portion is rotatably supported by means of the arm portion.
According to a fifth aspect of the invention, the display portion is provided on the arm portion so as to rotate around both a third rotation axis and a fourth rotation axis which intersect with each other.
According to a sixth aspect of the invention, the rotary portion is provided so as to rotate around the first rotation axis which extends in a direction intersecting the ceiling, the arm portion is supported by means of the rotary portion so as to rotate around the second rotation axis intersecting the first rotation axis, the third rotation axis is arranged in parallel to the first rotation axis, and the fourth rotation axis is arranged in parallel to the second rotation axis.
According to a seventh aspect of the invention, the display apparatus further comprises a plurality of recesses formed in a concave manner in a wail face of the ceiling of the moving body, the recesses being adapted to contain the arm portion.
According to an eighth aspect of the invention, the recesses are different in directions from one another and formed so as to radially extend from a mounting position of the rotary portion with respect to the ceiling.
According to a ninth aspect of the invention, the display apparatus comprises a second recess provided in at least one of a plurality of the recesses at a position remote from the mounting position of the rotary portion with respect to the ceiling, the second recess being adapted to contain the display portion.
According to the first aspect of the invention, the display portion is supported by means of the rotary portion by way of the arm portion. For this reason, as the rotary portion rotates with respect to the ceiling of the moving body, the display portion extensively moves in the moving body. In case where a plurality of seats are provided in the moving body, the rotary portion is rotated to move the display portion extensively, whereby the display portion can be substantially faced with the seats respectively.
According to the second aspect of the invention, the arm portion is rotatably supported with respect to the rotary portion, and the display portion can extensively move in the moving body more reliably.
According to the third aspect of the invention, the rotary portion is rotatable around the first rotation axis which intersects the ceiling, and the arm portion is rotatable around the second rotation axis which intersects the first rotation axis. Accordingly, the display portion can extensively move in the moving body more reliably.
According to the fourth aspect of the invention, since the display portion is rotatably supported by means of the arm portion, the display portion can extensively move in the moving body more reliably.
According to the fifth aspect of the invention, since the display portion is rotatably supported by means of the arm portion so as to rotate around both the third rotation axis and the fourth rotation axis, the display portion can extensively move in the moving body, and at the same time, the display portion can be more reliably faced with the seats respectively.
According to the sixth aspect of the invention, since the third rotation axis is arranged in parallel to the first rotation axis, the display portion can extensively move in the moving body, and at the same time, the display portion can be more reliably faced with the seats respectively.
Moreover, since the fourth rotation axis is arranged in parallel to the second rotation axis, the display portion can be displaced from a position along the ceiling to a position where the display portion is faced with the passengers seated on the seats.
According to the seventh aspect of the display apparatus of the invention, since the recesses formed in a concave manner in the wall face of the ceiling contain the arm portion, the mounting space can be saved.
According to the eighth aspect of the display apparatus of the invention, since a plurality of the recesses extend in a radial direction from the mounting position of the rotary portion with respect to the ceiling, the respective recesses contain the arm portion saving the mounting space, and in addition, the display portion can extensively move in the moving body more reliably, and at the same time, the display portion can be more reliably faced with the seats respectively.
According to the ninth aspect of the invention, since the second recess can contain the display portion, the sec
