  First, a first embodiment of the overturn prevention device according to the present invention will be described with reference to FIG.

  This overturn prevention tool 1 has a steel substrate 11 in a shape in which two flat plate portions 11a and 11b are connected via a bent portion 11c, and a viscoelastic mat 12 is provided on the back surfaces of both flat plate portions 11a and 11b. The plate-like magnet 13 is attached to the back surface of the one flat plate portion 11a along with the viscoelastic mat 12 near the bent portion 11c.

  The board | substrate 11 is bundled so that a width | variety may become thin at the bending part 11c, and the round hole is drilled in the center part of the bending part 11c. As a result, the rigidity of the bent portion 11c is slightly weakened, and the bending angle can be adjusted to some extent by bending the flat plate portions 11a and 11b by hand from the basic state where the plate portions 11a and 11b form a right angle. One flat plate portion 11a is slightly longer than the other flat plate portion 11b.

  The viscoelastic mat 12 is an isobutylene-based seismic gel that adheres to the substrate 11 by a self-adhesive action and exhibits buffering properties by elasticity. The magnet 13 is attracted to the substrate 11 by magnetism, and an extension portion from the side edge of the substrate 11 is bent, is held by the extension portion, and is held at a predetermined position.

  In the state before adhesion to the adherend surface, the thickness A of the viscoelastic mat 12 is larger than the thickness B of the magnet 13 as shown in FIG. A step C is provided between the adhesive surface and the attracting surface of the magnet 13.

  In order to prevent the furniture from falling using the tipping prevention tool 1 as described above, for example, as shown in FIG. 2, a strip-shaped release paper 14 is folded and adhered to the adhesive surface of the viscoelastic mat 12. The flat plate portion 11a is along the top surface of the furniture F, which is a magnetic body such as a locker, and the flat plate portion 11b of the substrate 11 is along the wall surface W.

  At this time, the end of the release paper 14 is extended and picked up, and the provisional positioning of the tipping prevention tool 1 is performed with the release paper 14 sandwiched between the viscoelastic mat 12 and the wall W and the top surface of the furniture F. Do. In this state, since the viscoelastic mat 12 is not adhered to the wall surface W and the top surface of the furniture F, the position of the fall prevention tool 1 can be adjusted by appropriately shifting.

  In addition, it is confirmed whether the angle formed by the flat plate portions 11a and 11b of the substrate 11 matches the angle formed by the wall surface W and the top surface of the furniture F. If the angle does not match, the substrate 11 is bent by hand. The angle formed by the flat plate portions 11a and 11b is adjusted. Thereby, the viscoelastic mat 12 can be brought into contact with the wall surface W and the top surface of the furniture F uniformly.

  Then, when the release paper 14 is pulled out from between the viscoelastic mat 12, the wall surface W and the top surface of the furniture F while lightly holding the substrate 11, the viscoelastic mat 12 sticks to the wall surface W and the top surface of the furniture F and falls. The prevention tool 1 is fixed to a predetermined position.

The elastic mat 12 strongly adheres to the top surface of the furniture F, thereby preventing the tipping prevention device 1 from moving in a direction away from the wall surface W, and the viscoelastic mat 12 is also attached to the wall surface W on the flat plate portion 11b side. Since it adheres firmly, the fall of furniture F can be reliably prevented when an earthquake occurs.

  In this construction state, the magnet 13 is not intended to fix the fall prevention tool 1 to the wall surface W by its attractive force, but extrudes air from between the viscoelastic mat 12 and the adherend surface, and the viscoelastic mat 12. It is supposed to strengthen the adhesive strength.

  When the wall surface W is a non-magnetic material that the magnet 13 does not attract, such as a wall with a wallpaper on a plaster board, as shown in FIG. 4, a metal mounting auxiliary plate that is a magnetic material on the wall surface W. 15 is attached with screws or nails reaching a base material such as a stud, the magnet 13 is adsorbed along the flat plate portion 11a on the auxiliary mounting plate 15, and the flat plate portion 11b is put along the top surface of the furniture F to be viscoelastic. It can be set as the attachment form which adheres the mat | matte 12 to the attachment auxiliary | assistant board 15 and the top | upper surface of the furniture F. FIG.
