Description

  The present invention relates to a fall prevention device. The overturn prevention device according to the present invention can effectively prevent, for example, a large television receiver from overturning due to vibration such as an earthquake.

As household television receivers become larger and thinner, there is an increased risk that the receiver and the room may be damaged due to an earthquake and that people may be harmed.
Conventional fall prevention devices for large-sized television receivers for home use have been proposed. For example, a television receiver is connected and fixed by connecting and fixing the rear bottom of the television receiver and the upper surface of the receiver rack with a connecting jig. An apparatus for preventing a machine from falling on a rack is known (Patent Document 1). However, in this apparatus, the television receiver and the rack are completely fixed, and it is impossible to change the direction of the screen of the television receiver on the rack. Even if the television receiver and the rack are connected, the rack is not fixed to the wall or the like, so the television receiver may move with the rack during a large earthquake. However, there is a problem that the risk of damage increases rather than the television receiver moving or overturning alone.

  In addition, when a thin large television receiver is installed and installed on an installation screen, there is also known a screen fixing device for fixing the screen to the ceiling to prevent the device from falling over (Patent Document 2). However, this device needs to fix the pole holding the television receiver between the ceiling and the floor, and is not used to prevent the fall of a home-use thin large-sized television receiver. It is a large-scale device that is expected to be used in a thin large television receiver. Further, after fixing, it was impossible to change the screen direction of the television receiver.

  Furthermore, the television receiver and the rack are fixed with a connecting jig, and the rear surface and the wall surface of the television receiver are connected with a string so that the television receiver falls from the rack, and the television receiver. There is known an apparatus that prevents the frame from moving forward (forward on the screen side) together with the rack (Patent Document 3). However, in this apparatus, since the back surface and the wall surface of the television receiver are connected by a string, even if the television receiver can be prevented from moving forward in the event of an earthquake, The television receiver and the rack move together and collide with the wall surface, and there is a risk that the wall surface and the television receiver may be damaged. was there.
