Abstract

PROBLEM TO BE SOLVED: To solve the problem that conventionally, in falling preventive measures of furniture, it is difficult to move furniture or the like because the furniture is fixed to a wall surface or a floor surface or support bars or the like are between an upper part of the furniture and a ceiling for fixation and also some furniture incorporates a falling prevention device inside and so it is difficult to easily attach the preventive measures to existing furniture.

SOLUTION: A falling prevention device 1 primarily includes: a front surface plate 7; a lower surface plate 8 in an integral structure with the front surface plate 7; a support plate 9 connected to the front surface plate 7; and a locking plate 10 for operating the support plate 9. In accordance with inclination of an object 4 due to shaking of an earthquake, the falling prevention device 1 falls to shift the locking plate 10 to an operation state, so that a support plate pusher 19 operates, and the support plate 9 protrudes in an inclination direction of the object 4. With this structure, it is possible to prevent the object 4 from falling due to shaking of an earthquake and the like.

Description

The present invention relates to a device for preventing objects from falling due to shaking such as an earthquake.

To prevent furniture from falling due to shaking caused by earthquakes, etc., you can use metal fittings to fix the furniture to the wall or floor, or use tension rods between the top of the furniture and the ceiling to prevent furniture from falling due to shaking caused by earthquakes. We are taking measures to prevent falls.

Furthermore, various structures are known as conventional fall prevention devices for furniture and the like. Patent Document 1 mainly relates to an overturn prevention device that can accurately prevent storage furniture from overturning without damaging floors, walls, and the like.

In the fall prevention device disclosed in Patent Document 1, when storage furniture is tilted at a predetermined angle using shaking caused by an earthquake, a protruding body protrudes in the tilting direction, and the lower end of the protruding body touches the floor. Prevent storage furniture from falling over.

Further, as a conventional fall prevention device, a structure shown in Patent Document 2 is known. This is a fall prevention device that prevents office furniture, shelves, and other furniture installed and used indoors from falling over, primarily as an earthquake countermeasure.

In the fall prevention device disclosed in Patent Document 2, the support rod detaches from the holding member and falls downward due to shaking during an earthquake, and engages with the regulating member, thereby preventing the furniture from falling over. .

Further, as a conventional fall prevention device, a structure shown in Patent Document 3 is known. Mainly, it is a fall prevention device that normally does not get in the way, but when earthquake vibrations are applied, the support legs immediately deploy to prevent office equipment from falling or moving during an earthquake.

The fall prevention device disclosed in Patent Document 3 is housed in a main body of office equipment, rotates horizontally due to earthquake vibration and its own weight, and deploys support legs and extension support legs to prevent the main body of office equipment from falling or moving.
