Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a view showing a flat display device according to the present invention attached to a wall surface or the like, in which an image surface thereof is in a horizontal state and a state in which the image surface is in a vertical state. As shown in the figure, a display unit 1 having a flat image unit 2 on the front surface is supported by a back plate 3 screwed to a wall surface or the like, and the image surface is changed from horizontal to vertical or vertical to horizontal. The angle can be easily changed. FIG. 2 is an exploded perspective view of the flat display device. A rotary shaft 4 is erected at the center of the back surface of the display unit 1. The rotary shaft 4 is formed in a stepped shape, and a small-diameter rotary shaft 5 having a screw hole 5a at its tip is provided. A guide shaft 6 is erected above the rotary shaft 5 and
Is similarly formed in a step shape, and the step surface is the same as the step surface of the rotary shaft 5. A small-diameter shaft 6a of the guide shaft 6 is provided with a key 6c having a ridge in the longitudinal direction, and
A screw hole 6b is provided at the tip thereof. The back plate 3 that supports the display unit 1 is provided with L-shaped flanges 7 on both sides, and through holes 7 a are formed above and below the flange 7. A support hole 8 corresponding to the diameter of the rotary shaft 5 of the display unit is formed in the center of the rear plate 3, and an arc-shaped elongated hole corresponding to the guide shaft 6 with the support hole 8 as the center. 9 is provided. A pair of locking holes 10 are provided on the periphery of the elongated hole 9 on the radiation centering around the support hole 8 with the elongated hole 9 sandwiched therebetween, and the locking hole 10 extends along the elongated hole 9. Are provided in multiple rows. The knob 13 has a disk provided with a screw portion corresponding to the screw hole 5a of the rotary shaft 4. Both ends of the stopper 11 correspond to the same locking hole 10 and have a spherical tip with a locking pin 1
1a is provided in a protruding manner, and in the center thereof is formed an insertion hole 11b through which the guide shaft 6a is inserted, and a key groove 11c of a recess in which the key 6c of the guide shaft is locked is provided in the insertion hole 11b. The spring 12 is made of steel and has a string-like shape.
4 is provided with a screw portion 14b corresponding to the screw hole of the guide bar at the center of the disc-shaped pressing portion 14a.

The procedure for assembling the display device having the above structure will be described. The display portion 1 is provided in the support hole 8 of the back plate 3.
6a of the rotary shaft 6 of
The display part 1 is rotatably supported on the back plate 3 by inserting the b parts into the elongated holes 9 and screwing the knobs into the screw holes 6b of the rotary shaft 6a. While inserting the insertion hole 11b of the stopper 11 into the tip of the guide shaft 6,
The key 6c is fitted in the key groove. As a result, the stopper 11 is supported by the guide shaft 6 so as to be slidable back and forth. Next, the spring 12 is fitted on the guide shaft 6a, and the screw of the pressing tool 14 is screwed into the screw hole 6b at the tip of the guide shaft 6 to hold the spring 12 and the stopper 11. As a result, the spring 12 presses the stopper 11 against the back plate 3.

The stopper pin 11b of the stopper pressed by the spring 12 is engaged with the stopper hole 1 of the rear plate 3.
When it is inserted into 0, the display unit 1 is fixed at that angle. If you want to change the angle of the display unit 1,
When is rotated, the locking pin 11a of the stopper 11 is disengaged from the locking hole 10, and when the locking pin 11a is fitted into the locking hole 10 at an arbitrary angle, the display unit 1 is fixed at that angle. As a result, the display unit 1 can be changed from the horizontal type to the vertical type and from the vertical type to the horizontal type, and when a list is displayed vertically on the display unit screen,
The display device can be easily used.

As another embodiment, as shown in FIG. 4, corrugated concavities and convexities are formed on both sides of the arcuate hole 9 of the back plate 3, and the stopper is used as an arbitrary engaging portion of the stopper. There is also a way to fix it in position. Further, as shown in FIG. 4 (B), when the back plate 3a is supported by the bracket 17 so as to be slidable vertically and vertically, and the angle of the display screen 1 is changed, the display screen 1 can be moved to a height or a position that is easy to see. There is also a structure.

[0010]

As described above, in the flat-panel display device according to the present invention, the display screen can be changed to a vertical type or a horizontal type, and can be set diagonally if necessary. In the case of a list display or the like, a vertical screen which is easy to display can be used, and a horizontal screen is usually used to provide a convenient display device.
