Abstract

PROBLEM TO BE SOLVED: To obtain an LCD monitor, capable of preventing the destruction of an LCD panel 11 at tumbling. SOLUTION: The LCD monitor having an LCD panel 11 has a tumbling protecting bar 14, which protects the LCD panel 11 against direct impacts in case the monitor tumbles. This tumbling protective bar 14 projects from the flank of the LCD panel 11 to the front surface side or back surface side of the LCD panel 11, thereby forming a collision preventive space on the front surface side or back surface side of the LCD panel 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LCD monitor, and more particularly, to an LCD monitor having a protection mechanism for protecting an LCD panel from a direct impact even when it falls down.

[0002]

2. Description of the Related Art Conventionally, as monitors for computers and the like,
CRT (cathode ray tube) display and LCD (liquid crystal dis
play) is known.

[0003] LCD monitors are superior to CRT displays in terms of space saving.
Recently, office and housing situations have been spreading rapidly with the help of them, and the size and thickness have been further reduced.

[0004]

However, LCDs
Since an LCD panel used for a monitor is an extremely expensive and delicate mechanism component, it is necessary to protect the panel portion from direct impact when the LCD monitor falls down. For this reason, for example, as a countermeasure against LCD panel destruction when the LCD monitor falls, there is an LCD monitor base provided with a fall prevention function, but when a situation occurs that exceeds the design condition of the fall prevention function, The LCD monitor inevitably falls.

An object of the present invention is to provide an LCD monitor which can prevent the LCD panel from being destroyed when falling down.

[0006]

In order to achieve the above object, an LCD monitor according to the present invention is an LCD monitor having an LCD panel.
It is characterized in that it is provided with a fall protection means for protecting the panel from direct impact.

[0007] With the above configuration, in the LCD monitor having the LCD panel, when the monitor falls down, LC
The LCD panel is protected from direct impact by the fall protection means provided in the D monitor. As a result, it is possible to prevent the LCD panel from being destroyed when it falls.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an LC according to an embodiment of the present invention.
It is a three-view figure showing appearance of a D monitor. As shown in FIG. 1, the LCD monitor 10 has a light-emitting surface exposed to
It has a main body case 12 on which a CD panel 11 is mounted, and a pedestal 13 supporting the main body case 12.

At the upper portions of both side surfaces 12a of the main body case 12, protection bars (overturn protection means) 14 are respectively provided.
Are mounted, and pressure-sensitive sensors (falling start detecting means) 15 are arranged at four corners of the bottom surface 13a of the pedestal 13, respectively.

The overturning protection bar 14 is formed in a plate shape, and the front (front side) or the back side (back side) of the LCD panel 11 is pivoted about the mounting portions 16 on both side surfaces 12 a of the main body case 12. ) To freely rotate the main body case 12
Can be changed by about 90 degrees from the state along the both side surfaces 12a to the state protruding toward the front side or the rear side of the LCD panel 11 (see the dotted line in the figure).

In the normal use state of the LCD monitor 10, for example, when the pedestal 13 is placed on a desk as a monitor mounting surface, four pressure sensors 15 individually sense the pressure, and Due to the falling start operation in which the pedestal 13 rises, the pressure is no longer sensed. The detection information detected by the pressure-sensitive sensor 15 is sent to control means described later.

The LCD monitor 10 is provided with a drive mechanism (not shown) for driving the fall protection bar 14 and a control means (not shown) for controlling the operation of the drive mechanism. The control means responds to the detection information input from the pressure-sensitive sensor 15 via the drive mechanism to control the overturn protection bar 14.
Is rotated to the front side or the back side of the LCD panel 11 and is held in a protruding state.

FIG. 2 is an explanatory view of the bottom surface of the base on which the pressure-sensitive sensor of FIG. 1 is arranged. FIG. 3 is an explanatory diagram of a state in which the LCD monitor of FIG. 1 has fallen.

When the LCD monitor 10 is energized, the pedestal 13
Either of the two pressure sensors 15a, 15b on the front side of the LCD panel 11 or the two pressure sensors 15c, 15d on the rear side (see FIG. 2) arranged on the bottom surface 13a of
When the pressure is no longer sensed, the fall protection bar 14 rotates in the direction in which the pressure-sensitive sensor 15 ceases to sense and is held in a protruding state.

For this reason, even if the LCD monitor 10 falls, the protection bar 14 at the time of falling becomes an abutting rod, and L
This prevents the CD panel 11 from directly hitting the mounting surface 17 of the LCD monitor 10 (see FIG. 3).
The panel 11 can be protected from direct impact. That is, the fall protection bar 14 forms a collision prevention space on the front side or the back side of the LCD panel 11.

FIG. 4 is a flowchart showing the operation of the LCD monitor shown in FIG. 1 when it falls down. As shown in FIG. 4, first, it is determined whether or not the front-side pressure-sensitive sensors 15a and 15b are in a pressure sensing state (step S101), and in the case of pressure sensing (Yes), the rear-side pressure-sensitive sensor 15c. ,
It is determined whether 15d is pressure sensing (step S10).
2).

Next, the pressure sensors 15c, 15d on the rear side
Returns to step S101 in the case where is pressure sensing (Yes), and in the case where pressure sensing is not (No), the overturn protection bar 14 is held in a state of protruding to the front side (step S10).
3), then terminate.

On the other hand, if it is not pressure sensing in step S101 (No), it is determined whether or not the pressure sensing sensors 15c and 15d on the rear side are pressure sensing (step S104). Is determined to have been lifted, and in the case of pressure sensing (Yes), the fall protection bar 14 is held in a state of protruding to the rear side (step S10).
5), then terminate.

That is, the front-side pressure-sensitive sensors 15a, 15a
When either b or the pressure sensor 15c or 15d on the rear side does not sense the pressure, it is determined that the front side or the rear side of the pedestal 13 is floating and separated from the mounting surface 17, that is, it is in a falling start state. I do.

The pressure sensors 15a, 15 on the front side
When the pressure sensor b does not sense the pressure, it is on the back side, and when the pressure-sensitive sensors 15c and 15d on the back side do not sense the pressure, it is on the front side, so that the overturning protection bar 14 is turned into a stick.

As a result, the protection bar 14 at the time of the fall is activated by the detection information from the pressure-sensitive sensor 15 for detecting the fall start operation. The impact can be prevented, and the LCD panel 11 can be protected (see FIG. 3).

As described above, according to the present invention, the LCD monitor 10 is provided with the fall protection bar 14 which can protect the LCD panel 11 from direct impact when the LCD monitor 10 falls. Even if you do
It is possible to prevent the LCD panel 11 from being broken.

[0024]

As described above, according to the present invention, in an LCD monitor having an LCD panel, when the monitor falls, the LCD panel is protected from direct impact by the fall protection means provided on the LCD monitor. So
The LCD panel can be prevented from being broken when it falls.
