The reason why the front and rear end heights of the first joint 150a and the second joint 150b are opposite to each other is that they are coupled to one coupling body 130 but do not overlap with each other. The first rotary shaft 153 of the first joint 150a is disposed higher than the first rotary shaft 153 of the second joint 150b and the second rotary shaft 153 of each of the first and second joints 150a, 155 are placed on the same line for leveling because they are coupled to the horizontal bar 125. [

The first and second joints 150a and 150b are normally fixed by being fastened to the separation pin 170. When the separation pin 170 is cut by an external force, the first and second rotation shafts 153 and 155, As shown in Fig.

The protruding piece 133 is formed with a hole 134 into which the separating pin 170 is inserted and the separating pin 170 is inserted into the connecting part 157 of the first joint 150a and the second joint 150b. Through holes 158 are formed.

The separating pin 170 has a cylindrical shape, and a cut groove 171 having a V-shaped cross section is formed at one side along the circumferential direction.

2 and 3, between the shelf frame 120 disposed at the lowermost portion or the uppermost portion and the column 110. The rectangular frame 120 is disposed vertically spaced to form a plurality of stages, It is preferable that a shock absorber 180 (shock absorber) is installed to absorb the shock. When the separating pin 170 is cut by the external force and the column 110 is inclined, the horizontal frame 125 and the horizontal frame 125 constituting the frame form move horizontally.

At this time, the shock absorber 180 not only absorbs a part of the external force transmitted from the ground due to an earthquake but also prevents the column 110 from being abruptly tilted when the separating pin 170 is cut, If it is missing, it restores to its original position due to elasticity.

11, when the external force is generated in the direction A, since the compression is performed in the right lower end and the left upper shock absorber 180, the column is pushed in the opposite direction to the compression direction Thereby preventing the column from leaning rapidly. Here, both ends of the shock absorber 180 are hinged to the column and the horizontal bar 125, respectively.

Hereinafter, a process of operating the first joint and the second joint when the column is inclined due to an external force acting on the earthquake-proof rack according to the present invention will be described.

10, when the external force acts on the earthquake-resistant rack in the direction A in the state of FIG. 10 (a), the column is inclined as shown in FIG. 10 (b), and then the separating pin 170 is cut The first joint 150a is inclined downward with respect to the column 110 so that the horizontal bar 125a is kept horizontal.

Referring to FIG. 11 together with FIG. 4, since the second rotation axis 155 of the second joint 150b rotates when the column is inclined in the A direction, the horizontal bar 125b is kept horizontal.

As described above, the first rotary shaft 153 and the second rotary shaft 153 are installed in the direction in which the first joint 150a and the second joint 150b are orthogonal to each other and the joints 150a and 150b are vertically rotatable. By providing the second rotary shaft 155 which can rotate left and right, the horizontal bars 125a and 125b can be kept horizontal regardless of an external force generated in any direction, and the shelf can be safely stored.
