DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention device for preventing furniture from falling due to an earthquake or the like.

[0002]

2. Description of the Related Art As a fall prevention device for preventing furniture from overturning due to an earthquake or the like, a fixing member protruding upward at a rear end of an upper surface of furniture and a through hole inserted into the fixing member are inserted into a wall surface. It is well known that the upper end of the furniture is connected to a wall surface to prevent the furniture from overturning.

[0003]

However, such a device for preventing the furniture from overturning has a drawback that it is not enough to reduce the vibration of the furniture due to a huge earthquake.

[0004] That is, since the upper end of the furniture and the wall surface are firmly connected by the fall prevention device, the vibration of the wall surface is directly transmitted and the furniture is shaken violently, and the distortion applied to the furniture becomes extremely large. Also, since an excessive impact force such as a pulling force applied to the bolt is applied to the overturn prevention device itself, the durability has to be reduced.

The object of the present invention is to solve these problems well.

[0006]

In order to achieve the above object, the present invention employs the following configuration.

[0007] That is, the furniture overturn prevention device according to the present invention comprises a vertical arm projecting upward at the rear end of the upper surface of the furniture;
A furniture fall-over prevention device comprising: a fixing member including a horizontal arm ; and a fixing member that is inserted into an insertion hole that opens to a vertical arm of the fixing member and that is fixed to a wall surface. between the head and the vertical arm, the vertical arm Rutotomoni, said horizontal arm is interposed plastic member with a predetermined thickness or more
With a front-to-rear dimension larger than the height of the
Only the part near the front end of this horizontal arm is fastened to the top of the furniture.
It is characterized by doing.

Further, a plastic member having a certain thickness or more may be interposed between the vertical arm of the fixing member and the wall surface.

It is particularly desirable that the plastic member is an elastic member.

[0010]

According to the furniture fall prevention device having such a configuration, even if a wall or the like vibrates due to a huge earthquake, the vibration is absorbed by the deformation of the plastic member, so that the vibration transmitted to the furniture is reduced. Not only can it be possible, but also the impact force applied to the overturn prevention device can be reduced at the same time, and the durability of the overturn prevention device can be improved. Moreover, with the addition of plasticizing member to such a configuration the conventional anti-toppling device, water
The flat arm has a front-rear dimension larger than the height of the vertical arm.
Only the part near the front end of this horizontal arm
Since it is only fixed to the upper surface , the structure is simple, does not increase the load of the assembling work, and does not cause any particular change in appearance.

[0011] Such an operation is basically sufficient if a plastic member is interposed between the head of the fastener and the fixing member. However, the plastic member is also interposed between the fixing member and the wall surface. By doing so, it is possible to synergistically enhance the fall prevention effect by operating the vibration isolation function not only in the falling direction but also in the returning direction.

Further, when the plastic member is an elastic member, it can be returned to its original shape after the end of the vibration and can be used repeatedly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the overturn prevention device 1 is provided at a plurality of locations on a rear end 2a of an upper surface of a storage furniture 2 having a known configuration attached to a wall surface W. The upper surface rear end 2a and the wall surface W are connected. As shown in FIG. 2, the fall prevention device 1 includes an L-shaped fitting 3 as a fixing member, a bolt 4 as a fastening tool, and two elastic members 5 and 6 as two plastic members.

The L-shaped bracket 3 includes a horizontal arm 31 and a horizontal arm 31.
And a vertical arm 32 projecting upward from the rear end. The horizontal arm 31 is attached to the rear end 2a of the upper surface of the storage furniture 2 and fixed by bolts 311 and nuts 311a. The horizontal arm 31 is larger than the height of the vertical arm 32
With a large front-back dimension, only in the vicinity of the front end
Is fixed to the upper surface of the storage furniture 2. The vertical arm 32
An insertion hole 321 is opened.

The bolt 4 has a head portion 41 and a shaft portion 42. The bolt portion 4 is inserted into the insertion hole 32 of the L-shaped bracket 3.
1 and screwed into an engaging hole 43 formed in the wall surface W and fixed.

The elastic members 5 and 6 are made of a plate-like high elastic rubber material having a certain thickness or more.
The insertion hole 51, 61 having a diameter slightly larger than the shaft portion 42 of the bolt 4 is formed so that the shaft portion 42 of the bolt 4 is inserted.
Between the vertical arm 32 of the bracket 3 and the head 41 of the bolt 4,
The elastic member 6 is slightly interposed between the vertical arm 32 of the L-shaped bracket 3 and the wall surface W.

With such a fall prevention device 1 for the storage furniture 2, even if the wall surface W and the bolt 4 screwed to the wall surface W violently vibrate together with the storage furniture 2, the vibration of the storage furniture 2 in the falling direction does not occur. The deformation of the elastic member 5 and the vibration of the storage furniture 2 in the return direction are absorbed by the deformation of the elastic member 6, respectively. For this reason, not only can instantaneous vibrations transmitted to the storage furniture 2 be greatly reduced, but also the impact force applied to each part of the overturn prevention device 1 including the bolt 4 is simultaneously reduced to prevent overturning. The durability of the device 1 can be improved. In addition, since it is a simple configuration in which only the elastic members 5 and 6 are added to the conventional fall prevention device, the load of the assembling work is not increased, and the appearance is not particularly changed.
Although it can be easily applied, it has a high practical effect. Furthermore, since the elastic members 5 and 6 return to the original shape after the end of the vibration, the elastic members 5 and 6 can be repeatedly used, and high durability can be secured for the device itself.

The configuration according to the present invention is not limited to the above-described configuration. For example, a metal cylinder or the like may be used as the plastic member, and the vibration may be reduced by deforming with a large vibration. Further, the fixing member is not limited to the L-shaped fitting, and for example, a part that protrudes in advance from the upper rear end of the furniture may be used as the fixing member. Further, the fastening device is not limited to the bolt, but may be an anchor having a known configuration. Furthermore, an elastic member may be interposed between the lower end of the storage furniture and the floor surface to further effectively reduce the vibration. In addition, various modifications such as the material and shape of each member are possible without departing from the present invention.

[0020]

The furniture fall prevention device according to the present invention comprises:
As described in detail above, it is possible not only to reduce the vibration transmitted to the furniture, but also to simultaneously reduce the impact force applied to the fall prevention device and improve the durability of the fall prevention device. become. Moreover, the configuration is simple,
Since it does not increase the burden of the assembling work and does not bring about any particular change in appearance, it can be easily adopted and has a high practical effect.

In particular, by using the elastic member as the plastic member, the elastic member can be returned to its original shape after the end of the vibration and can be used repeatedly, and the durability as a fall prevention device can be further improved. It becomes possible.

As described above, the present invention has a special effect that it is possible to simultaneously reduce the impact force applied to the furniture and the overturn prevention device with a simple configuration, and also enhance the durability of the overturn prevention device. To play.
