Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat display display support device, and more particularly, to a flat display display form of two or three screens as required, and a display direction can be arbitrarily selected. The present invention relates to a flat display display supporting device that can be used.

[0002]

2. Description of the Related Art In recent years, the application range of personal computers has been dramatically expanded, and a display method using a multi-screen has been realized as one of the application ranges.

[0003] The contents of the display are used, for example, in the case of financial institutions such as securities companies and banks, for displaying average stock prices and brands, and in cases where a wide field of view is required when creating graphics. This is a very effective method as a means for a plurality of persons to see the same screen from multiple directions, or for a single operator to see a plurality of related screens at the same time and obtain information from each direction at the same time.

[0004] If the display is of a flat type made of liquid crystal, the display is not self-sufficient in itself. Therefore, the individual flat displays are supported on individual supports and arranged side by side. A plurality of support arm devices capable of holding the flat display are installed, and the flat displays are individually supported by the support arm devices so that the flat displays are developed in parallel.

[0005]

However, in the above-mentioned conventional means, the setting of the screen orientation of each flat display and the manner of display are greatly restricted, and it is difficult to make the layout easy for the user to see and use. There was a problem.

In view of the above, the present invention provides a flat display display in which two or three flat displays can be supported in various directions by one supporting device, and the screen can be set to the most visible form. An object of the present invention is to provide a support device for a vehicle.

[0007]

SUMMARY OF THE INVENTION As means for solving the above-mentioned problems, the present invention provides a fixed base, a first main shaft erected on the base, and a rear left / right position of the first main shaft. Two second base shafts erected, a short center arm pivotally supported on the first base shaft in a horizontal plane, and at least two center arms supported on the second base shaft so as to be pivotable in a horizontal plane. The present invention is configured to have a flat display supporting portion for mounting a flat display at each end of the center arm and the side arm.

[0008] Thus, by mounting the flat display on the flat display support portions of the left and right side arms and removing the flat display support portion of the center arm, two flat displays can be juxtaposed. By selecting the bending state of the side arm, the screen can be displayed with the flat displays closely spaced or separated from each other.

If a flat display is also mounted on the flat display supporting portion of the center arm, three flat displays can be installed side by side. By selecting the bending state of the side arm, it is possible to arrange the flat display horizontally. Alternatively, the flat displays on both sides can be arranged in the form of a trihedral mirror at an angle to the central flat display.

Further, the flat display can be arranged in three directions depending on the bending state of the side arm.

At the bases of the center arm and the side arms, bearing cylinders which are fitted to and rotate with the first base shaft and the second base shaft are provided. If the three base shafts are restrained to be fixed, a stable state can be obtained without swinging of the three base shafts, and when the side arms are three arms, the third base shaft pivotally supported by the second base shaft can be obtained. If one arm is formed longer than the second arm and the third arm,
This is preferable because the position of the flat display supported by the side arms can be easily adjusted.

The flat display supporting portion has a first bracket pivotally supported on each end of the center arm and the side arm so as to be rotatable in a horizontal plane, and has a left and right portion mounted on the first bracket so as to be able to adjust a vertical position. A second bracket attached to the second bracket and a support which is attached to the second bracket via a tilt unit so as to be tiltable and on which a flat display is mounted. The support can be adjusted in a vertical direction and a turning direction. it can.

When the fulcrum of the shaft 37 is tilted, a predetermined torque is given by the frictional force generated by tightening the coil springs 39, 39.

Next, the operation of the above embodiment will be described with reference to FIGS.

FIGS. 9 and 10 are a plan view and a front view, respectively, of a case where two FDs 11 and 11 are arranged and supported in parallel so that the screen is horizontal and straight. Then, the shaft 27 of the FD support portion 3 is removed, the FD support portion 12 is removed, and the FDs 11, 11 are mounted on the FD support portions 12, 12 of the side arms 4, 4. The FD 11 is attached to the outer surface of the FD mounting surface portion 24c of the support 24.
Attach the lower surface with screws.

The first arm 4 _1, 4 ₁ a wall 4 of the side arms 4, 4 FD11,11 as described above is mounted
0 is rotated to be parallel, folded the second arm 4 ₂ so as to overlap on the first arm 4 ₁ is the state of FIG. 9 shows by pivoting the third arm 4 ₃ obliquely forward .
According to this usage mode, it is effective when one operator works to view two screens from the front.

In FIG. 9, reference numeral 40 denotes a wall surface or a surface of another object.

FIGS. 11 and 12 show the FDs 11 mounted on the FD supports 12 of the center arm 3 and the side arms 4 and 4, and the screens of the FDs 11, 11 and 11 are supported side by side so as to be horizontally aligned. FIG. 3 shows a plan view and a front view in the case where the side arms 4 and 4 are used.
By bending each of the arms 4 ₁ , 4 ₂ , and 4 ₃ in a zigzag shape, the usage patterns shown in FIGS. 11 and 12 can be obtained.

When the FDs 11 and 11 on both sides supported by the side arms 4 and 4 are to be directed to the center like a three-sided mirror, the FDs 11 supported on the center arm 3 by slightly extending the side arms 4 and 4. Can be arranged at an angle γ.

FIG. 13 shows FDs 11 and 1 from three different directions.
FIG. 3 is a plan view of a usage form in which the screens of the first and the first arms 11 and 11 can be seen. When the FD 11 supported by the center arm 3 is the front, the FDs 11 and 11 supported by the side arms 4 and 4 are inclined. to face the rear is achieved by bending the arms ₄₁ to the _third side arms 4,4-shape in plan view "4".

In the above-mentioned usage form, particularly in the case of FIGS. 11 and 12, the center arm 3 has a short length because the arm itself is short.
Although the D support portion 12 is unlikely to be lowered, the side arms 4 and 4 are formed by connecting a plurality of arms, so that when the weight (approximately 8 to 9 kg) of the FD 11 is added, the side arms 4 and 4 may be lowered or tilted.

In this case, first, the fixing screws 30, 30 of the FD support portion 12 are loosened, and the adjusting screws 28, 28 are turned to rotate the second bracket 22 with respect to the first bracket 21.
Of the FD 11 by adjusting the vertical position or inclination of the FD 11 so that the screen is horizontal and at the same level as that of the FD 11 at the center, and then tightening the fixing screws 30 and 30 to fix the second bracket 22 at that position. , 11,11
Can be set in a state of being aligned in a horizontal line.

Although some typical examples of use have been described above, the side arms 4 and 4 can be arbitrarily selected within the movable range according to the purpose of use and the purpose of use. Also, depending on the size of the FD 11, the side arms 4 and 4 may be 2
It may be constituted by the arms 4 ₁ and 4 ₂ .

[0036]

As described above, according to the present invention, a plurality of flat displays can be supported by a single support device having a support arm structure, so that the flat displays can be easily installed, and both sides can be easily installed. The side arm has a structure in which at least two arms can be bent in a horizontal plane, so that the orientation of the flat display can be changed according to the purpose of use of the user or the use of the screen, such as horizontal row, three-sided mirror, multi-sided The most suitable form can be selected according to it.
