Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a partition fixing device that is arranged between a partition upper portion for installing a flat TV and a ceiling surface and prevents the partition from falling over.
[0002]
[Prior art]
Conventionally, a flat television using a large screen PDP (Plasma Display Panel) or the like is mounted on a screen for installation so that the height, position or direction of the screen can be easily seen.
[0003]
FIG. 6 is a side view showing an embodiment of a flat television set installed on a conventional screen.
Reference numeral 1 denotes a flat television using, for example, a PDP (Plasma Display Panel). Reference numeral 2 denotes a partition provided with a columnar portion having an attachment portion at a central portion for installing the flat television 1 and holding the attachment portion on both sides.
Reference numeral 3 denotes a base placed on the floor surface 4 for installing the partition 2 in a vertical state. 4 is a floor surface.
[0004]
As shown in FIG. 6, a partition 2 is installed in a vertical state on a base 3 placed on a floor surface 4, and the flat television 1 is attached to a required height on the partition 2. By the way, when the flat-screen television 1 is a 42-inch PDP (Plasma Display Panel), for example, it has a weight of about 40 kg and the center of gravity O of the PDP is at a high position from the floor surface 4, so the installation state is quite unstable. It becomes easy to fall by a little external force. When a heavy PDP falls, it not only destroys the PDP itself, but is also dangerous for nearby people. In particular, as shown in FIG. 6, when the PDP is installed forward from the center of the partition, since the center of gravity O is in front of the partition, a moment in the direction of falling forward acts on the partition, making it easier to fall.
[0005]
Therefore, a large base 3 is used for the partition as a conventional measure for preventing the fall. In other words, the base 3 on which the screen is vertically suspended has a substantially inverted T shape in the longitudinal section, and the front-rear distance of the front portion of the screen is increased.
As shown in FIG. 6, for example, when the center of gravity O of a 42-inch PDP is held at a height of 1.2 m, the angle at which the center of gravity P of the PDP looks at the floor 4 is θ, for example, θ <= 60 degrees. If it is difficult to fall, the base 3 needs to have a front-rear distance of about 60 cm from the partition. In other words, the base 3 must be at least 60 cm forward from the screen.
However, the base 3 having such a large front-rear distance has a problem that a large floor area is required for installation. Further, for example, in the case of a PDP or the like equipped with a touch panel, there is a problem that it is difficult to touch the touch panel because the front portion of the base 3 is in the way and cannot sufficiently approach the screen.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a screen fixing device that is difficult to fall over even if it is supported by a ceiling, in spite of a small installation floor area.
[0007]
