Description

Technical field to which the invention belongs

  The present invention relates to a preventive technique for preventing furniture or shelves that have been subjected to earthquakes or external vibrations from falling in a utility space in front of the furniture, causing injury to people and drowning, especially cabinet furniture. The present invention relates to an effective earthquake countermeasure technology that is provided in indoors, office rooms, and work places where people are permanently present, such as ornaments around shelves and canteens.

  Conventional anti-earthquake equipment for furniture is generally fixed to surrounding structures, and is rigidly installed on the floor, and a brace is inserted between the ceiling and furniture or between the furniture and the left and right walls. Many things are installed and fixed. Hereinafter, the vibration that furniture and the like receives from outside due to an external cause is referred to as external vibration.

  However, even if these fixed countermeasure products do not cause the furniture or the like to fall forward, a shocking concentrated load is generated at the leading edge of the countermeasure product that hits the furniture or the like, which may damage the furniture or the structure.

  Therefore, we learned that the flexible structure in which the five-storied pagoda is easy to move as a whole with a pillar structure for furniture and other fixed countermeasure products will not collapse for more than a thousand years. In addition, proposals have been made for a configuration in which furniture and the like are driven. The first of those proposals is to insert a product that sandwiches and integrates a single sphere with a set of two plate-shaped plates at the bottom of the floor furniture (Patent Document 1), and the second is at the bottom of the furniture. A multi-compartment circular case containing one sphere is used as a countermeasure product, and the ball rolls in an emergency and absorbs the impact on the furniture (Patent Document 2).

Even in the structure adopting these improvement measures, the initial position of the furniture or the like is not always a stationary position at the end of the vibration, and there is a drawback that if there is a step around the furniture, it causes a fall.
As a third countermeasure, there is a proposal for controlling an unnecessary movement by attaching an electromagnetic stopper to a furniture or the like along with a sphere sandwiching structure (Patent Document 3). According to this proposal, even if no forward accident occurs, the proposed electromagnetic stopper is fixed, so that the range of movement when the vibration ends is controlled. However, furniture tends to rotate around the stopper, and the stationary position at the end of the vibration of the furniture or the like is not necessarily the initial position before the vibration as in the above proposal.

Therefore, the seismic isolation method of placing a computer etc. where the object is always present at a fixed position on the floor at the time of vibration, the damage-free free-access seismic isolation floor coming from the top and bottom and the horizontal direction solves the above deficiencies. . In the fourth proposal, a skid prevention sphere, a floor contact sphere, and a vertical motion absorbing spring structure are combined (Patent Document 4). This improvement is a technique related to the modification of the entire floor.
However, it is more complicated and larger than the above three proposals, and does not correspond to furniture individually. In particular, there is a problem that it cannot be applied to structures in existing buildings.
Even if the above-described fall prevention technology is a seismic isolation measure for furniture or the like, it cannot be applied to a storage form in which shelves, such as bowls and tableware, are placed on one shelf using the same technology.
