ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a support device of a display for supporting a display body in a manner pivotable in the horizontal plane and in the vertical plane. The present invention can be used for a support device (a stand device) of a thin type display such as a liquid crystal display or a plasma display.
2. Description of the Prior Art
FIG. 11
is a perspective view of a display device
80
using a conventional support device
82
viewed from the backside.
As shown in
FIG. 11
, the display device
80
comprises a display body
81
and the support device
82
. The support device
82
includes a pedestal portion
91
having substantially a rectangular shape viewed from the bottom and a stand portion
92
.
A swivel unit
93
having a circular shape viewed from the bottom is attached to the bottom of the pedestal portion
91
. The swivel unit
93
supports the pedestal portion
91
in a manner pivotable in the horizontal plane. The swivel unit
93
is placed on a surface of a desk or an appropriate table. The bottom surfaces of feet
94
provided in the bottom surface of the pedestal portion
91
are floated with a little clearance toward the surface of the desk or the table, or have a light contact with the same.
The upper front surface of the stand portion
92
is provided with a tilting attachment portion
95
, to which the backside of the display body
81
is attached in a manner pivotable in the vertical plane.
Therefore, when holding and turning the pedestal portion
91
or the display body
81
in the horizontal direction, they can swing by the swivel unit
93
with respect to the surface of the desk or the table.
In the above-mentioned conventional support device
82
, the swivel unit
93
contacts the surface of the desk or the table so as to support the entire body of the display device
80
. However, the swivel unit
93
has a circular shape, and its bottom area is substantially smaller than that of the pedestal portion
91
, and the feet
94
are floating from the surface of the desk or the table. Therefore, there can be some rattle between the surface of the desk or the table and the pedestal portion
91
, resulting in reducing stability to some extent.
In addition, if the surface of the desk or the table is uneven or slanting, the bottom surfaces of the feet
94
, can contact the surface of the desk or the table, so that the movement of the swivel unit
93
pivoting in the horizontal plane cannot be performed smoothly.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a compact support device of a display for supporting a display body stably. According to one aspect of the present invention, a device is a support device of a display for supporting the display body in a manner pivotable in the horizontal plane and in the vertical plane. The support device comprises a substrate, an upper cover attached thereto, a middle cover being partially sandwiched between the substrate and the upper cover so as to be pivotable in the horizontal plane, and a tilting unit being attached to the middle cover and having a pivoting arm being pivotable in the vertical plane and being attached to the display body.
Preferably, the middle cover includes a cylindrical portion, a top plate portion provided on the upper end surface thereof, a ring plate portion extending outward in the horizontal direction from a periphery of the lower end surface of the cylindrical portion and a protruding shaft portion projecting downward from the middle portion of the top plate portion, and the protruding shaft portion is inserted in a pivot support hole provided substantially in the middle portion of the substrate in pivotable manner, and the ring plate portion is sandwiched between the substrate and the upper cover in pivotable manner so that the vertical movement is restricted.
In addition, the tilting unit includes two supporting members attached to a boss portion provided in the middle cover with screws that are inserted from the bottom, and the pivoting arm includes two leg portions that are pivotable with respect to the two supporting members and a coupling portion that couples integrally the two leg portions at the upper end portions thereof, and the coupling portion is provided with a hole or a protrusion for mounting the display body.
