  However, the fall prevention device provided with a tension between the ceiling and the upper surface of the furniture disclosed in Patent Document 1 and Patent Document 2 has a problem that a large force is applied to the ceiling during an earthquake and the strength is required for the ceiling.

  Moreover, since the fall prevention tool disclosed by patent document 3 fixes the member of height larger than furniture between a ceiling and a floor, an apparatus becomes large and installation takes time. The fall prevention tool disclosed in Patent Document 4 has a complicated structure because the support member protrudes before and after the fixture during an earthquake.

  In Patent Document 5, since a pin is raised so that the fall prevention tool laid under the furniture does not come off during an earthquake, the fall prevention tool is difficult to come off, but the problem that the furniture slides on the floor together with the fall prevention tool during an earthquake remains.

  In view of the above-described circumstances, an object of the present invention is to provide a simple tipping prevention tool that prevents furniture such as a refrigerator and a storage shelf from slipping out or tipping over during an earthquake.

  The fall prevention device according to the invention is a fall prevention device that is inserted between the bottom surface of the fixture and the mounting surface on which the fixture is placed, and prevents the fixture from falling down in the event of an earthquake, and is erected on the mounting surface described above The standing member and an inclined member that is inclined rearward from the vicinity of the upper portion toward the placement surface, wherein the inclined member has a space between the placement surface and the above-described placement of the standing member or the inclined member. A portion in contact with the surface has a first anti-slip portion.

  A standing member that is erected on the placement surface, and an inclined member that is inclined from the vicinity of the upper portion thereof toward the rear side toward the placement surface, wherein the inclined member has a space between the placement surface and the standing member. Or since the part which contact | connects the said mounting surface of the said inclination member has a 1st slip prevention part, insertion from the front surface of a fixture is easy, and it can prevent a slip prevention part from slipping out by a slip prevention part.

  The fall prevention tool of the present invention is characterized in that a portion of the inclined member that contacts the bottom surface has a second anti-slip portion.

  Since the portion of the inclined member that contacts the bottom surface has the second anti-slip portion, the tipping prevention tool is in close contact with the bottom surface of the fixture to prevent the fixture from moving and falling during an earthquake.

  The fall prevention tool of the present invention is characterized in that a plurality of grooves substantially perpendicular to the tilt direction of the tilt member are provided on the upper surface of the tilt member.

  Since a plurality of grooves substantially perpendicular to the inclination direction of the inclined member are provided on the upper surface of the inclined member, the fixture is difficult to slip, and the anti-slip member bites into the groove, thereby improving the anti-slip effect.

  The fall prevention tool of the present invention is characterized in that the first anti-slip portion or the second anti-slip portion is constituted by an anti-slip member.

  Since the first anti-slip portion or the second anti-slip portion is constituted by an anti-slip member, the anti-slip portion can be constituted by appropriately selecting an anti-slip member having a large friction coefficient.

  The fall prevention tool of the present invention is characterized in that the anti-slip member is a vinyl chloride sheet or a silicon resin sheet.

  Since the anti-slip member is formed of a readily available vinyl chloride sheet or silicon resin sheet, the overturn prevention tool can be configured at low cost.

  In the fall prevention device of the present invention, when the fall prevention device is inserted between the bottom surface of the fixture and the mounting surface on which the fixture is placed, the inclined member is bent, and the second anti-slip portion is attached to the fixture by its elastic force. It is characterized in that it is pressed against the bottom surface.

  When the fall prevention tool is inserted between the bottom surface of the fixture and the mounting surface on which the fixture is placed, the inclined member bends and the second anti-slip portion is pressed against the bottom surface of the fixture due to its elastic force. Can be obtained.

  The fall prevention tool of the present invention is characterized in that the inclined member is formed of a synthetic resin material.

  Since the inclined member is formed of a synthetic resin material that is easily available, the fall prevention tool can be configured at low cost.

Conventional fall prevention tool

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a fall prevention tool 10 inserted between a fixture such as a refrigerator and a floor as a mounting surface. The overturn prevention tool 10 includes a main body 2 formed of a synthetic resin material having elasticity, for example, a soft vinyl chloride material, and a non-slip sheet 1 having a large friction coefficient covering the main body 2. The non-slip sheet 1 is fixed to the main body 2 with an adhesive, a double-sided tape or the like. Here, the right side of the drawing in which the anti-tip tool is inserted is the rear side of the anti-tip device, and the left side of the figure standing in front is the front of the anti-tip device.

  FIG. 2 shows a side view of the overturn prevention device 10 including the standing member 21 and the inclined member 22. The main body 2 is composed of a standing member 21 that is in contact with the floor and an inclined member 22 that is inclined toward the floor from the vicinity of the upper portion thereof, and between the end of the standing member 21 and the end of the inclined member 22. There is a space between the floor. The end portion of the standing member 21 or the end portion of the inclined member 22 is covered with the anti-slip member 1 as the second anti-slip portion, but when covering with a single sheet, it is preferable to cover both. The anti-slip member 1 to be used is preferably a flexible synthetic resin material such as a vinyl chloride sheet or a silicon resin sheet.

  A plurality of grooves 3 are formed on the upper surface of the inclined member 22 in a direction substantially perpendicular to the direction of the arrow into which the tipping prevention tool 10 is inserted. When the anti-tip device 10 is inserted between the bottom surface of the fixture, the lower portion of the bottom surface of the fixture and the inclined member 22 come into contact with each other, and the anti-slip member 1 serving as the first anti-slip portion bites into the groove 3 to prevent the slip. 1 is reliably held and displacement is prevented.

  The space between the inclined member 22 and the floor 50 is substantially triangular. When the overturn prevention tool 10 is inserted between the lower surface of the furniture and the floor, the inclined member 22 is deformed, so that the insertion becomes easy. Further, since the inclined member 22 is deformed and bent, it is repelled by an elastic force and the adhesion between the anti-slip portion 2 and the lower surface of the fixture is improved, and the anti-slip effect is ensured. Also, pressure is applied to the floor surface due to the elasticity of the main body portion 2, and the drag in the horizontal direction increases due to an increase in the coefficient of friction with the floor surface by the anti-slip member 1 serving as the second anti-slip portion.

  A mechanism for preventing overturning by the overturning prevention tool 10 will be described with reference to FIG. 4A is a steady state refrigerator placed in front of the wall 60, and the overturn prevention device 10 is inserted into a portion between the level adjusters in front of the refrigerator. The weight of the refrigerator is supported by a level adjuster provided at the front P and a sliding leg provided at the rear Q. Since the fall prevention tool 10 changes its height depending on the depth of insertion, the tilt member 22 of the fall prevention tool hits the lower part of the bottom of the refrigerator and is pushed to the extent that the tilt member 22 begins to deform.

  FIG. 4B shows the state of the refrigerator that is tilted forward to maintain the current position of the center of gravity of the refrigerator according to the law of inertia even if the floor moves backward due to an earthquake or the like. When the floor moves to the right due to the earthquake, the level adjuster has a small coefficient of friction with the floor, so the refrigerator tries to slide forward, but the tipping prevention device 10 having a non-slip portion prevents the refrigerator 40 from moving forward. .

  Since the rear part Q of the refrigerator 40 tilted forward hits the wall 60, the refrigerator can be prevented from falling. Moreover, the fall prevention tool 10 which was crushed and deformed by the bottom face of the refrigerator inclined forward exerts a force to the refrigerator to return the refrigerator to its original state by elasticity.

  The procedure for mounting the fall prevention tool 10 to the refrigerator will be described with reference to FIG. The front part of the refrigerator is equipped with two level adjusters, which are adjusted to stabilize the installation. The space between the two level adjusters is covered with the leg cover, so pull it toward you to remove the leg cover (FIG. 4A).

  The fall prevention tool 10 is inserted into the gap between the leg cover mounting portions (FIG. 4B). In that case, it pushes in enough and inserts so that the lower part of the bottom face of a refrigerator may contact the inclination member 22 of the fall prevention tool 10. FIG. After inserting the fall prevention tool 10, the leg cover is attached to the original position (FIG. 4C).

  FIG. 6 shows a conventional fall prevention tool. Hard plastic is used for the material of the fall prevention tool used conventionally. Tilt the fixture to prevent falling to the back and make a gap between the floor and the bottom of the fixture so that the lower part of the fixture hits the fall prevention tool. If it does so, a fixture will be in the form which can be lifted by the fall prevention tool, and will prevent falling forward by tilting toward the back. However, this fall prevention tool is difficult to apply to a fixture having a large gap between the bottom of the fixture and the floor. Also, when the material is hard plastic, the coefficient of friction with the floor is small, so there is a problem that the fixture starts to slide forward during an earthquake.

  On the other hand, the fall prevention tool 10 according to the present invention can cope with the change in the size of the gap by selecting the height of the standing member so that the gap between the lower portion of the bottom of the refrigerator and the floor is filled. In addition, it is not necessary to tilt the refrigerator for installation. Furthermore, since it has a non-slip portion, it is possible to prevent the refrigerator from sliding forward in the event of an earthquake. The effect of the fall prevention tool according to the present invention was confirmed by experiments.

  The embodiment described above is a part of the present invention, and embodiments including the technical idea of the present invention are included in the technical idea of the present invention.
