[0003]

However, in the case of a rod-shaped support, it is sufficient if the floor slab of concrete or the like is directly used as a ceiling downstairs, but most ceilings are covered with a gypsum board or the like as a base. If the upper part of the bar is pressed firmly against the ceiling surface, the ceiling surface is easily lifted or damaged. Further, in offices and the like, a ceiling construction method in which a board is mounted on the edge of a dressing field is often used, so that a bar-shaped support cannot be used. Further, in a simple L-shaped bracket, in a normal partition wall in which a board is stretched on a metal stud having a substantially U-shaped cross section, the board-clamped surface of the strut easily opens toward the front if a pulling force is applied. . For this reason, even if a long L-shaped bracket that is attached to a plurality of studs is used, especially in the case of an office, it is desirable to arrange a number of furniture side by side. There is a difference in height before and after, but this cannot be accommodated. Furthermore, in the L-shaped bracket, a large force is applied to the bent portion in order to receive vertical movement of the furniture when a pitching earthquake occurs in a plane attached to the furniture, that is, a plane applied with a force applied in a vertical direction. Was added, and the bent part was sometimes destroyed. That is, a conventional rod-shaped support or L
In the case of an earthquake or the like, there is a problem that the metal fittings cannot sufficiently function as a furniture fall prevention tool.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a furniture fall prevention device having high strength and excellent earthquake resistance.
