Description

  The present invention relates to a rack overturn prevention device for preventing a rack from overturning.

  Conventionally, in order to prevent the rack or the like from overturning, a method of passing a tension rod between the upper surface of the rack and the ceiling or a method of fixing the wall and the rack with a hook has been taken.

  However, with the conventional rack fixing method, it may come off in the case of vibration more than the tension bar can withstand, and if the rack and ceiling and the tension bar are not installed in the vertical state during installation, There was a thing lacking in a sense of stability that could not exert the effect.

  Also, when fixing the wall and rack with hooks, the screw holes in the wall opened to screw the hooks gradually become loose, and the screws can be easily removed by repeated earthquakes, etc. There was a problem that it was necessary to open and fix the screw holes again.

Furthermore, in the case of rearrangement of racks, it has been very troublesome to newly install a tension bar or to make a screw hole for a hook.
