Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to furniture equipped with an earthquake-resistant mechanism.

[Background of the idea]

In particular, tall furniture such as chests of drawers is unstable during installation, and when a house shakes during an earthquake, for example, the furniture may topple over, causing a disaster. In order to prevent such disasters caused by furniture falling over, it has been considered to use special mounting brackets to fix furniture to the walls or pillars of houses. Mounting brackets cannot be easily attached to walls, etc., and even if they can be easily attached to the walls of wooden houses, they are not strong enough to cause furniture to fall over. There are problems such as difficulty in obtaining sufficient mounting strength to prevent earthquakes, and existing furniture is generally not equipped with earthquake-proofing measures, so in the event of a strong earthquake, the furniture may be damaged. It is expected that many accidents and disasters will occur due to overturning.

[Purpose of invention]

In order to prevent such disasters caused by furniture toppling over, the present invention has developed furniture equipped with a disaster prevention mechanism that operates by sensing the seismic intensity, thereby preventing shaking caused by earthquakes, etc. It is an object of the present invention to provide furniture that can prevent the furniture from falling sideways by operating its sideways prevention mechanism when such a situation occurs.

[Example of idea]

The present invention will be explained in detail below based on embodiments shown in the drawings.

1 is furniture such as a vertical chest of drawers, and this furniture 1
A support rod insertion tube 3 having an opening 2 on the front side is diagonally installed in the left and right side walls of the rod.
The vertical position of the opening 2 of the support rod insertion tube 3 is preferably about 1/3 from the bottom of the height of the furniture 1. A support rod 4 is inserted into and out of the support rod insertion tube 3 . The support rod 4 inserted into the support rod insertion tube 3 is
By the elastic action of the stopper 5 attached to the support rod, the support rod is normally held so that it will not be pulled out from the support rod insertion tube 3. 6 is a vibration detector having a weight 7 with a heavy head, but this vibration detector 6 is a vibration detector 6 conventionally used as an earthquake-resistant automatic fire extinguishing device for a stove.
Since the structure and operation of the vibration detector 6 are the same, a detailed description of the structure of the vibration detector 6 will be omitted. Reference numeral 8 denotes a lever that is operated when the weight 7 falls sideways, and this lever 8 is connected to the stopper 5 via a wire 9.
is connected to. Further, a ratchet 10 is formed on the back surface of the upper end of the support rod 4, and the ratchet 10 is configured so that an elastic locking piece 11 attached to the support rod insertion tube 3 can be locked therein. 12 is a return lever connected to the elastic locking piece 11 via a wire 13.

Next, to describe its effect, if an earthquake occurs and the furniture 1 shakes, the weight 7 of the vibration detector 6 will fall down as a result of this shaking, and as a result, if the wire 9 is pulled, the stopper 5 is pulled and the pressing force on the support rod 4 inserted into the support rod insertion tube 3 is released, so the support rod 4 falls due to its own weight, and the lower end of the support rod 4 touches the floor as shown in the figure. 14. The support rod 4 that has fallen in this way is exposed to the ratchet 10 formed on the back surface of the support rod 4.
is locked by the elastic locking piece 11, so that the support rod 4
Since there is no reverse movement of the furniture, that is, there is no push into the support rod insertion tube 3, the support rod 4 in contact with the floor surface 14 can effectively prevent the furniture from falling sideways. If you want to store this support rod 4 into the support rod insertion tube 3 again, pull the return lever 12 to release the locking force between the ratchet 10 and the elastic locking piece 11, and then return the support rod 4 to its original position. It can be stored in place to provide vibration resistance during the next vibration. In the above embodiment, the support rod insertion tube 3 is provided, but instead of this insertion tube 3, a guide path such as a groove or a rail may be used.

[Summary of the idea]

As described above, the present invention provides the inclined guide path 3 on the side surface of the furniture, which is inclined downwardly toward the front of the furniture, and whose opening is formed in the front surface of the furniture. A support rod 4 that can be disposed of by its own weight is inserted through the opening, and the furniture also has a support rod 6 housed in the inclined guide path 3.
locking means to prevent the expenditure of the furniture, and when the furniture swings.
This furniture is equipped with an earthquake-resistant mechanism characterized in that it is equipped with a vibration detector that operates the locking means in the releasing direction to cause the support rod 4 to be ejected from the opening by its own weight.

[Effect of idea]

Therefore, according to this furniture, when the furniture shakes due to an earthquake or the like, the vibration detector installed in the furniture is activated, and the support rod 4 is pushed forward by its own weight, causing the furniture to move. Since it acts as a support, it effectively prevents furniture from falling sideways even in the event of an earthquake, and has the effect of preventing accidents caused by furniture falling sideways.
