ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATION
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. '119 from my utility model application entitled Device for Flat Panel Display Device Compensating Hinge Joint Unit filed with the Korean Industrial Property Office on Dec. 12, 1997 and duly assigned Serial No. 97-36962 by that Office.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a flat panel display device, and more particularly, relates to a flat panel display device having a reinforcing member for reinforcing a connecting strength between a display unit and a hinge member which pivotally connects the display unit to a stand, enabling the visual angle of the display unit to be adjusted to a position according to the wishes of a user so that user can see data displayed on the flat panel of the display unit well.
2. Description of the Related Art
As shown in
FIG. 1
, generally, a flat panel display device includes a display unit
1
having a flat panel
2
and a stand
3
for rotatably supporting the display unit
1
. The display unit
1
is pivotally connected to the stand
3
by a hinge member
4
, so that the visual angle of the display unit
1
can be adjusted backwardly and forwardly, and right and left, if desirable, as shown in FIG.
1
.
The hinge member
4
is connected to the display unit I through rotating brackets
6
which are pivoted around a tilting shaft
5
as a center, in accordance with the backward or forward pivot motion of the display unit
1
. The flat panel
2
is attached to a front case
1
a
of the display unit
1
, and a rear case
1
b
of the display unit
1
. The rotating brackets
6
are connected to the rear case
1
b
of the display unit
1
. The rotating brackets
6
are made from metallic materials, the rear case
1
b
of the display unit
1
is formed by molding plastic materials and the bosses
1
c
are made from plastic materials.
The rotating brackets
6
for connecting the hinge member
4
with the display unit
1
are mounted to a plurality of bosses
1
c
formed at an inner surface of the rear case
1
b
by means of screws
7
. A portion of the hinge member
4
which is connected to the display unit
1
cannot be shown in front to enhance the external appearance of the display unit
1
.
However, in the conventional flat panel display device, a force is concentrated upon the bosses
1
c
to which the rotating brackets
6
are secured, when the display unit
1
is pivoted for adjusting the visual angle thereof. If the force acts on the bosses
1
c
repetitively, the screws
7
may be released from the bosses
1
c
and in turn the rotating brackets
6
may become separated from the rear case
1
b
, or the bosses
1
c
made from the plastic materials may be destroyed by the repetitive force, so that a bit of play occurs between the bosses
1
c
and the screws
7
. As a result, the visual angle of the display unit
1
cannot easily and accurately be adjusted due to the play when the display unit
1
is used over the long term.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a flat panel display device having an endurance which can be enhanced by reinforcing a connecting strength between a display unit and a hinge member.
Additional objects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
The above and other objects of the present invention can be attained by providing a flat panel display device which includes a display unit having a front case, a rear case, and a flat panel displaying an image; a stand to support the display unit and having a circular recess provided at a top portion thereof; a hinge member having a tilting shaft, a rotating bracket secured to a lower portion of an inner surface of the rear case of the display unit and pivotable around the tilting shaft as a center of rotation, and a circular body fitted in the circular recess and rotatable in a range of a certain angle; and a reinforcing member secured to the inner surface of the rear case along with the rotating bracket by fasteners.
Also, the circular body has a plurality of protrusions formed at an outer circumference thereof, the circular recess has a plurality of grooves formed at an inner circumference thereof, the protrusions are engaged with the grooves, respectively, and the length of the protrusions is shorter than that of the grooves.
The rotating brackets are secured to the inner surface of the rear case by the fasteners. The reinforcing member preferably has a width and a length shorter than those of a lower side of the rear case.
