Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flat display device, and more particularly to a thin wall hanging tool provided with a long hole for installing a display panel on a wall.
[0002]
[Prior art]
Conventionally, flat display devices such as PDPs (Plasma Display Panels) have a slightly inclined state using a wall hanging tool equipped with a tilt mechanism for adjusting the mounting angle so that the screen can be viewed almost vertically. It is configured to be installed on a wall.
[0003]
FIG. 3 is a side view (b) showing a flat display device installed using a conventional wall hanging tool with a tilt mechanism, a side view (b) of the flat display device mounted in an inclined state, and a plan view through a main part. It is a top view (C) of a display apparatus.
Reference numeral 1 denotes a thin box-shaped flat display panel, for example, a PDP panel. Reference numeral 2b denotes a box-shaped first wall hanging member formed of a rectangular bottom portion installed on the wall surface 3 of the room, and a pair of vertical walls and a pair of horizontal walls suspended from the bottom portion. Reference numeral 2c denotes a substantially L-shaped plate-like second wall hanging tool. The lower end of the vertical wall of the first wall hanging tool 2b supports the L-shaped tip end portion with a rotating shaft 2f and the upper portion of the vertical wall. The provided projection 2e is inserted and locked into an arc-shaped elongated hole 2d provided at the end of the L-shape, and the pair of second wall hooks 2c are attached to the PDP panel 1 along the long side of the L-shape. Side by side at appropriate positions on the left and right sides.
With the above configuration, the PDP panel 1 is moved around the rotation shaft 2f in the direction of the arrow shown in FIG.
[0004]
By the way, the thickness (box thickness) B1 of the conventional first wall hanging tool 2b is substantially the length of the foot of the L-shaped portion in order to pivotally support the L-shaped second wall hanging tool 2c. Some degree of size is required. As described above, since the PDP panel 1 is attached to the L-shaped second wall hanging tool 2c, the PDP panel 1 can be set at an easy-to-see angle.
[0005]
However, since the thickness of the first wall hook 2b and the thickness of the second wall hook 2c are increased, the thickness B2 of the entire flat display device is increased. For example, even if a thin PDP panel is used, the thickness of the entire PDP device is reduced. There has been a problem that it has become large and it is difficult to realize a thin flat display device.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a thin flat display device that can freely set an attachment angle to a wall surface.

A pair of second stoppers for inserting the protrusions of the wall hanging tool into the holes, and four protrusions at corresponding positions on both side surfaces for insertion into the through holes of the first and second stoppers. It consisted of a display panel.
[0008]
In another configuration, the height of the L-shaped cross section of the wall hanging tool is reduced toward the lower end, and the plate has a plate-like shape with a through hole at the end, a long hole at the other end, and the wall hanging at the through hole. A pair of second fasteners are provided so as to be inserted through the protrusions of the tool.
[0009]
In addition, the long hole has an arc shape, the first stopper is fixed to the display panel, and the second stopper is fixed to the wall hook.
[0010]
Moreover, the said wall hanging tool, the 1st fastener, and the 2nd fastener were comprised with the sheet metal.
[0011]
In addition, the protrusion is constituted by a bolt, and a corresponding nut is provided, and the nut is screwed into the bolt inserted through the long hole to fix the first stopper or the second stopper.
[0012]
The nut is a wing nut.
[0013]
In another configuration, the wall-hanging tool is provided with a tongue piece having a through hole at a substantially central portion, and the display panel is provided with a protrusion at a position corresponding to the central portion. Is configured to pivotally support the protrusion.
[0014]
In addition, a pair of wall hanging tools having a L-shaped member for attaching to the wall surface and provided with a tongue piece having a through hole in the substantially central portion of the side surface of the member and having a protrusion at the lower end portion, A pair of fasteners having a through hole at one end and an elongated hole at the other end so that the projection of the wall hanging tool is inserted into the through hole, and both side surfaces for insertion into the through hole of the stopper The display panel is provided with a pair of protrusions at a position corresponding to the substantially central portion and a pair of bolts at positions corresponding to the lower ends of both side surfaces.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Since it comprised as mentioned above, in the state which makes the display panel substantially parallel to the wall surface and presses the display panel in the direction of the wall hanging device, the entire thickness of the flat display device becomes small. The protrusion of the first stopper inserted in the long hole moves to the wall surface side end of the long hole. In addition, the protrusion of the display panel inserted in the long hole of the second stopper moves to the display panel side end of the long hole.
(2) In a state where the display panel is inclined with respect to the wall surface by a predetermined angle, for example, 10 ° downward in the vertical direction, the upper end of the display panel moves forward. At this time, the protrusion of the first stopper inserted in the long hole of the wall hanging tool moves to the display panel side end of the long hole.
[0016]
In another configuration, the height of the L-shaped cross section of the wall hanging tool is made smaller toward the lower end. Therefore, while satisfying the above (1) and (2), the projection of the display panel inserted into the long hole of the second stopper moves to the wall side end of the long hole, and the thickness of the lower part of the device is small. Become.
[0017]
The bolt inserted into the long hole is fixed by screwing a nut.
[0018]
The display panel includes a display panel provided with a pair of protrusions at a substantially central portion on a side surface, and a pair of wall hanging devices provided with a tongue piece having a through hole at a substantially central portion. It is pivotally supported so as to rotate in the through hole of the tongue piece.
[0019]
