Looking at the vertical expansion of the frame 100 by the vertical expansion unit 550 with reference to Figures 12 to 14, the frame 100 and another frame to match in the vertical direction, protruding to the upper portion of the center frame 110 The first fitting protrusion 562 is inserted into the binding hole 564 formed on the lower surface of the another central frame 110.

At the same time, the second fitting protrusion 582 is formed to protrude to the top of the outer frame 150 is inserted into the lower guide groove 155 of the other outer frame 150.

In the above state, the coupling shaft 566 of the other center frame 110 is slid to insert and fix the through-hole 563 of the first fitting protrusion 562 transversely, and to another outer frame 150. The binding member 585 hingedly rotates to insert and fix the binding protrusion 586 into the through hole 583 of the second fitting protrusion 582.

Rotation of the binding member 585 is made by the rotation of the operating member 592, the operation member 592 is a binding member that is interlocked because the rotation state is fixed by the pressing force of the pressing member 594 with the elastic member is built in The rotation state of 585 can be maintained.

As described above, the center frame 110 and another center frame 110 are bound by the first upper and lower extensions 560, and the outer frame 150 and the other outer frame 150 at both sides are second upper and lower. Bound by the expansion unit 580 can connect another frame 100 to the upper or lower, and has a three-point support structure due to the variable length of the angle change unit 400 and the rotation bar 120 In the case of the curved frame 100, it may be firmly connected, and the angle may be changed by interlocking.

An alignment protrusion 572 is formed at a first fitting protrusion 562 and a tripod-shaped position on an upper surface of the center frame 110, and an alignment hole portion at which an alignment protrusion 572 is inserted at a lower surface of the other central frame 110 ( 574 is formed to set the correct position when the vertical connection of another frame 100, it can prevent the flow.

In addition, the light emitting module 300 mounted on the mounting bracket 210 is vertically coupled by the connecting protrusion 312 and the connecting groove 314 when the frame 100 is extended up and down, so that each light emitting module is disposed up and down. 300 may be linked.

That is, as shown in FIG. 15, another frame 100 may be continuously extended to the frame 100 by the side extension part 510 and the vertical extension part 550 in the upper and lower parts and the side, thereby implementing a large display board. In addition, various curvatures may be formed by changing angles.

As described above, according to the flexible display board according to the present invention, since both ends of the frame are rotated based on one point, and the light emitting modules arranged at a predetermined interval by the rotation of the frame are formed to be curved, they can be installed in various shapes. Various expressions are possible without restriction.

In addition, the present invention can provide a large display board by the expansion connection, it is possible to achieve a variety of curvature and display a completely different from the existing.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

Accordingly, the true scope of protection of the present invention should be defined by the claims.
