Description

The present invention relates to a furniture fall prevention tool, more specifically, a tool installed between the upper surface of the furniture and the ceiling, and when a vibration such as an earthquake occurs, the furniture is prevented from falling, And it is related with the furniture fall prevention tool which can absorb a part of said vibration.

  Furniture installed on the floor, such as a bag, bookcase, or cupboard, that has a certain height is easy to fall down due to vibrations such as an earthquake. For this reason, various tools for preventing the furniture from falling are being developed.

For example, there is known a pressing fixture including a column, an end surface in contact with the ceiling surface, and an end surface in contact with the furniture upper surface (for example, Patent Document 1 below). The press fixture is installed by adjusting the length of the column between the ceiling and the upper surface of the furniture, pressing one end surface against the ceiling surface, and pressing the other end surface against the furniture upper surface, and fixing the post. This is the type of a stick rod.

  As another fall prevention tool, use a chain or rope, and fix one end of the furniture to the ceiling or wall surface with a metal fitting, etc., and the other end to the side of the furniture with a metal fitting. A type that prevents the above is known (for example, Patent Document 2 below).

JP-A-8-228869 Japanese Patent Laid-Open No. 8-228871

  However, all of the conventional furniture overturn prevention tools described above have been proposed for the technical idea of preventing furniture overturning only by physical resistance such as pressure and tension, and each has its own problems. Had.

That is, the type of the tension rod type exemplified in Patent Document 1 exhibits an effective effect of preventing a fall when a relatively small scale earthquake occurs, but if a large scale earthquake occurs, it rolls. In some cases, the pillars fixed in an upright position such as the above are detached from the ceiling and the upper surface of the furniture, and do not play the role of preventing the fall. In addition, due to strong pitching, the end face of the support sometimes broke through the ceiling or furniture top surface.
Moreover, since the both ends of the column are pressed against the ceiling and the upper surface of the furniture with a considerable pressure and fixed in an upright posture, the ceiling surface and the upper surface of the furniture may be damaged.

In addition, the type that pulls the ceiling (or wall surface) and furniture with a chain or rope exemplified in Patent Document 2 is also used when a relatively small scale earthquake occurs in the same manner as the above-mentioned type of the tension rod. Is effective in preventing falls, but when the magnitude of an earthquake increases, the parts fixed with metal fittings are easily pulled out from the ceiling (or wall surface) or furniture surface, and the effect of preventing falls is exerted. There was no case.
In addition, the above-mentioned type has a problem in that the installation location is always damaged because the end of the chain or rope is fixed to the ceiling (or wall surface) and the upper surface of the furniture by metal fittings when installed. .

  The present invention has been made in view of the above-mentioned problems, and even when an earthquake with a large seismic intensity occurs, it can sufficiently prevent the furniture from falling over and can damage the ceiling and furniture during installation. It is intended to provide no furniture fall prevention tools.

  The present invention does not prevent furniture from falling only by physical resistance, but by realizing two performances of earthquake resistance and vibration control with one tool, when a large earthquake occurs In addition, based on the technical idea that the effect of preventing the furniture from falling down can be satisfactorily exhibited, a furniture falling prevention tool made of a foamed resin molded body has been completed.

Is a summary.

  In the present invention, the term “upper bottom surface” refers to a portion located on the uppermost surface when the present invention is installed on a horizontal surface. That is, in the present invention consisting only of the foamed resin molded body, it means the upper surface of the foamed resin molded body, and in the present invention in which the fitting member is fitted into the hole of the foamed resin molded body, When the upper surface and the upper surface of the fitting member are located at the same height, the upper surfaces are collectively referred to as the upper bottom surface, and are fitted with the upper surface of the fitting member protruding from the upper surface of the foamed resin molded body. The upper surface of the fitting member is referred to as the upper bottom surface.

In the present invention, the term “lower bottom surface” refers to a portion located on the lowermost surface when the present invention is installed on a horizontal plane. That is, in the present invention consisting only of the foamed resin molded body, it means the lower surface of the foamed resin molded body, and in the present invention in which the fitting member is fitted into the hole of the foamed resin molded body, When the lower surface and the lower surface of the fitting member are located at the same height, the two lower surfaces are collectively referred to as the lower bottom surface, and the lower surface of the fitting member is located higher than the lower surface of the foamed resin molded body. When the height adjusting member is filled in the height adjusting space generated by the above, the lower surface of the foamed resin molded body and the lower surface of the height adjusting member are collectively referred to as a lower bottom surface.

  In the present invention, the term “upper surface” or “lower surface” refers to the upper surface as the upper surface and the lower surface as the lower surface when the furniture overturn prevention device of the present invention is installed on a horizontal surface.

  The furniture overturn prevention tool of the present invention is mainly composed of a foamed resin molded body. By sandwiching the present invention made of the foamed resin molded body between the ceiling and the upper surface of the furniture, the present invention becomes a physical obstacle, preventing the furniture from falling over in the event of an earthquake and generating vibration. Thus, a part of the external pressure according to the present invention can be absorbed by the foamed resin molded body and reduced. That is, the furniture overturn prevention device of the present invention exhibits both earthquake resistance and vibration control during an earthquake, and as a result, exhibits an excellent overturn prevention effect.

In addition, since the present invention can be installed by simply sandwiching the foamed resin molded body between the ceiling and the upper surface of the furniture, the ceiling surface and the upper surface of the furniture are not damaged, and the attaching operation is easy.

  Furthermore, since the conventional anti-tip tool described above is in a disorderly manner with the interior decoration on the upper surface of the furniture such as the pillars and chains, both have poor appearance, and improvements were desired from the viewpoint of interior decoration, The present invention has a good appearance. In particular, in the present invention in which a decorative sheet is laminated on at least a part of the side surface, the appearance is even better, and harmony with the interior decoration is possible.

  In addition, laminating the decorative sheet on the side surface of the foamed resin molding of the present invention is not limited to improving the aesthetics. When the present invention collides with another object during transportation of the furniture fall prevention tool of the present invention, or after the installation of the present invention between the ceiling and the furniture, the other object is the side of the present invention in the event of an earthquake. Even when a physical impact is applied to the side surface of the foamed resin molded body in the present invention, such as when it hits the surface, the impact is alleviated and the side surface of the foamed resin molded body is protected by the presence of the decorative sheet. It is done. As a result, it is possible to satisfactorily prevent the foamed resin molded body from being damaged due to the physical impact.

Furthermore, the further effect described below is exhibited by laminating the decorative sheet on the side surface of the foamed resin molding of the present invention. That is, when the present invention installed between the ceiling and the upper surface of the furniture receives an axial pressure between the ceiling surface and the upper surface of the furniture in the event of an earthquake, the decorative sheet is placed on the side surface of the foamed resin molded body. If laminated, the effect of suppressing the transverse strain in the direction perpendicular to the axial direction to be small and preventing the foamed resin molded body from being destroyed is exhibited. In addition, the protective effect from the physical impact mentioned above and the effect which suppresses the said lateral strain small are exhibited especially favorable, when a decorative sheet is laminated | stacked on the side surface substantially whole periphery of a foamed resin molding.

In addition, the joining method of the compression deformation layer 3 and the main body 2 described above is merely an example, and does not intend to exclude those joined by another method from the present invention.

Further, the main body 12 in which the hole 18 shown in FIG. 3 is formed is formed by first molding a foamed resin molded body block, and then hollowing the cylindrical hole 18 with hot teeth or the like to form the hole 18 ( The hole side forming method 1), or cutting the side surface of the main body from a part of the side surface of the main body 12 to the contour portion of the hole portion 18 using thermal teeth, and foaming along the planned contour portion of the hole portion 18 from the point of arrival. The resin molded body may be cut and cut (hole forming method 2). In the hole forming method 1, the cut side surface portion of the main body 12 is cut by means for closing with an adhesive, means for reinforcing the side cut portion with tape or the like, or laminating a decorative sheet around the entire body. The cut side portions can be supplemented by means for reinforcing the side portions or a combination of these means.
