Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-screen display device which can easily arrange a plurality of heavy display units.

[0002]

2. Description of the Related Art As a device for displaying an image on a large screen, there is a projection type display device. A multi-screen system in which multiple rear-projection display units are arranged vertically and horizontally to project and display images from the back of a transmissive screen with a projector that uses liquid crystal or the like to provide a large screen and high-definition display. A display device is used. In a multi-screen display device, the width of the joint of the screen is required to be narrow. Therefore, the screen has a laminated structure reinforced with a transparent material due to its configuration. Therefore, the mass of the display unit increases, and for example, in the case of a 50-inch screen size, the mass increases from 40 kg to 50 kg. Therefore, it is not easy to assemble a multi-screen display device in which a plurality of the display devices are arranged vertically and horizontally.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide means for easily assembling a multi-screen display device even when a heavy display unit is used. .

[0004]

SUMMARY OF THE INVENTION An assembly of a multi-screen display device is provided in which a rotation mechanism is provided on the bottom surface of the display unit above the two display units that are vertically stacked and on the upper surface of the lower display unit. At times, the upper display unit can be slidably moved on the upper surface of the lower display unit so that the display unit can be easily assembled even when the display unit is heavy.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is an assembly view showing one embodiment of a multi-screen display device according to the present invention,
(B) is a plan view of one display unit, and (C) is a bottom view of one display unit. The display unit 10 displays an image by projecting from the rear of the transmissive screen 10c with a projector (not shown). Display unit 2 similar to display unit 10
The multi-screen display device 100 is configured by arranging 0, 30, and 40 vertically and horizontally. A plurality of rotating mechanisms 21 are provided on the bottom surface 20b of the display unit 20 disposed on the display unit 10.
a, 21b and 21c are provided. When assembling the multi-screen display device 100, the rotation mechanism 21a, 2
1b and 21c are rotated and slidably moved in the lateral direction. Therefore, even when the mass of the display unit 20 is large,
It can be easily installed at a predetermined position.

[0006] On the bottom surface of the display unit 20 on the upper side, there is provided a groove 22 extending in the sliding direction by the rotating mechanisms 21a, 21b, 21c. A spar 12 is provided on the upper surface of the lower display unit at a position corresponding to the groove 22 of the upper unit 20 to fit into the groove 22. When assembling the multi-screen display storage device 100, the spar 12 on the upper surface of the lower display unit 10 is used.
Then, the groove 22 of the upper display unit 20 is fitted to slide on the upper surface of the display unit 10. The screen surfaces of the display unit 10 and the display unit 20 can be easily adjusted by the groove 22 and the spar 12. If the fitting surface of the spar 22 or the groove 12 is made of Teflon having a small coefficient of friction, the sliding becomes easier.

A rotating mechanism 21 provided on the bottom surface 20b of the display unit 20 above the upper surface 10a of the lower display unit 10.
In the corresponding portions of a, 21b, and 21c, there are provided escape holes 11a, 11b, and 11c for loosely inserting the rotation mechanism 21a and the like. After assembling the multi-screen display device 100 with the upper display unit 20 being at a predetermined position above the lower display unit 10, the rotating mechanism 21a and the like are loosely inserted into the through holes 11a and the like, so that the display unit 10 Screen 1
0a and the screen 20c of the display unit 20 are in close contact with each other, and joints disappear. The rotation mechanisms 21a, 21b, 21
c and the through-holes 11a, 11b, 11c are provided at positions that do not overlap on a straight line in the lateral direction, which is the sliding direction, respectively.
Before the rotation mechanism slides to a predetermined position, the rotation mechanism is prevented from being loosely inserted into the through hole in the near side.

FIG. 2A is a plan view of a rotating mechanism of a multi-screen display device according to an embodiment of the present invention, and FIG.
It is a side view. An ear 213 is provided on the rotation mechanism 21, and the ear 213 is screwed with a screw 214 from inside the housing on the bottom surface 20 b of the upper display unit. When assembling the multi-screen display device, the wheel 211 of the rotating mechanism 21 rotates around the support shaft 212 on the upper surface of the lower display unit, and the upper display unit is slidably moved to a predetermined position. After installation at a predetermined position, the screw 214 is removed from inside the rear housing of the upper display unit, the rotation mechanism 21 is removed, and the upper display unit is brought into close contact with the lower display unit.

[0009]

According to the present invention, a rotating mechanism is provided on the bottom surface of the display unit above the two display units which overlap each other and the upper surface of the lower display unit constituting the multi-screen display device, and the lower display is provided when the multi-screen display device is assembled. By allowing the upper display unit to slide on the upper surface of the unit, the display unit can be easily assembled even when the display unit is heavy, and the number of assembling steps can be reduced.
