By rotating the block by the rotation coupling unit, the neighboring block is rotated so that the other block is in contact with the two surfaces on both sides adjacent to each other while making the other block perpendicular to the one surface with respect to one surface of the one block. and,
The rotary coupling part,
So that the blocks are hinged to each other,
First and second fixing pieces each of which is fixed to an upper surface of one of the two contacting surfaces and a lower surface of the other contacting surface on the surface where the blocks are in contact with each other, and the other portions thereof are not fixed;
A third fixing piece which is fixed to the lower surface of the one and the upper surface of the other, and the other portions are not fixed;
Folding structure comprising a hinge axis disposed in the folding portion of the first to third fixing pieces.
The folding structure of claim 1, wherein the block is formed in two or more shapes.
The method of claim 1,
The block is a folding structure, characterized in that formed in a frame having a space therein.
The method of claim 3,
The block has a triangular cross section, the frame is formed with a coupling seat to the rotatable coupling portion,
The rotation coupling unit, the folding structure, characterized in that the one or more rotation fixing piece which is fixed so as to be rotatable in each of the coupling position and the other coupling position of the side in contact with each other.
The method of claim 3,
The block has a rectangular cross section, the frame is formed with a coupling seat on which the rotary coupling portion can be seated,
The rotation coupling portion, the first and second fixing pieces which are rotatably fixed to one of the upper coupling seat and the other coupling seat of the side that the blocks are in contact with each other,
And a third fixing piece which is rotatably fixed to one lower coupling seat and the other upper coupling seat, respectively.
The folding toy which consists of a folding structure of any one of Claims 1-5.
Folding furniture comprising the folding structure according to any one of claims 1 to 5.
A folding luminaire comprising the folding structure according to any one of claims 1 to 5, wherein a light emitting unit is installed inside or outside the block, and electricity is connected by the rotation coupling unit. delete delete delete delete delete delete delete
