Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing side slipping and falling of an installation body, and more particularly to a structure for preventing side slipping and falling of an installation body that can stably hold a heavy installation body such as a piano even when an earthquake occurs.

  An installation body such as an upright piano has a weight of about 200 kg to 300 kg and is a structure having a high center of gravity. Therefore, when an earthquake occurs, a side slip or a fall is likely to occur. In particular, for example, the Great Hanshin-Awaji Earthquake can cause the piano itself to be a weapon, so it is necessary to take measures to prevent the piano from sliding or falling.

  As a general fall prevention measure, a structure is known in which a bracket made of a metal piece is spanned between the installation body and the wall surface, and this bracket is fixed to the wall surface and the installation body with screws or the like. Since a piano is a musical instrument, it is not preferable to fix a bracket or the like using screws, nails or the like.

  By the way, in Patent Document 1, a belt with metal fittings attached to both ends is used, and an overturn prevention device is provided that tries to prevent the installation body from overturning by applying tension while the belt is wound around the installation body. Is disclosed.

Utility Model Registration No. 3112455

  However, the fall prevention device described in Patent Document 1 is a method in which one metal fitting is fixed to the top plate of the installation body using screws or the like, and it is assumed that the installation body is damaged. There is an inconvenience that it cannot be adapted to the anti-seismic structure. Further, since the belt is structured to be hung along the upper surface and the back surface of the installation body, it is not necessarily an effective anti-seismic structure for side slip in the left-right direction of the installation body. .

  Furthermore, since the metal fixture fixed to the wall surface is not in a state where the weight of the installation body is added, in the case of a heavy installation body, the metal hardware itself is torn off from the wall surface when a strong vibration occurs. From this point as well, it cannot be adapted to prevent side slipping and falling of the installation body such as a piano.
