Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that reliably prevents furniture from falling over without damaging the furniture.

In this specification, the term "ceiling" refers to anything that has a surface that is generally parallel to the top surface of furniture, and includes, for example, the bottom surface of a strongly fixed shelf or the bottom surface of a beam. .

Our country is said to be responsible for 10% of the world's earthquakes, so everyone knows how terrifying earthquakes are, but countermeasures are extremely lenient from the policy level to the individual level. If a large-scale earthquake were to occur, mountains and cliffs would crumble, tsunamis would easily cross breakwaters, flooding would occur, brick walls would fall, all large furniture in homes would topple over, and so on, resulting in an extremely serious situation. There is a risk of causing panic.

Furthermore, although there are a considerable number of these disasters that can be prevented at the individual level, one of them is the overturning of large furniture, which should be considered as an earthquake countermeasure, as well as the fall of children playing on the drawers of a chest of drawers. There have been a number of accidents in which people have fallen over and become trapped under the furniture, resulting in injuries, and there have also been incidents where furniture has fallen over and knocked over stoves, causing fires.

Traditionally, large furniture has been fixed to walls and ceilings with strings or fasteners to prevent it from falling over, but since these methods require the use of nails, expensive furniture and It is difficult to actively do this as it will damage walls and ceilings, and in the unlikely event that furniture begins to topple over due to children's play or an earthquake, the initial vibration will cause damage. If it came off or broke, it would be completely meaningless, and if the preventer itself had to be removed due to moving furniture, etc., it would be a hassle to remove the nails.

In addition, recently, one-floor type condominiums with wide floors, for example, are often seen, but in such places, the rooms are often partitioned with tall furniture, and the only place to secure such furniture is the ceiling, which is not the case in the past. By law, it was likely to be difficult to fix.

Therefore, in view of the above points, the inventor of the present invention has conducted extensive research and found that the prevention of falling furniture is extremely reliable, does not damage furniture or ceilings, and is easy to attach and detach tools used. He invented a device to prevent furniture from falling over.

The apparatus of the present invention will be described in detail below based on embodiments shown in the drawings.

FIGS. 1a and 1b show the method according to the invention for preventing furniture 2 from tipping over in a situation where it is placed against a wall 1. FIGS. As is clear from the figure, the furniture 2 will not fall to the left because the wall 1 is on its left side. In addition, furniture such as chests of drawers that are generally installed near walls are often long and narrow along the wall, so the risk of falling is towards the right side of the diagram, in other words, clockwise. I can say that.

Therefore, the fall prevention device 3 is first fixed on the upper surface of the furniture 2. This fall prevention device 3 is installed on the upper surface of the furniture 2 and on the ceiling 4.
It consists of a support 5 that is slightly longer than the distance from It is performed at an angle.

The end 51 of the support 5 is in contact with the ceiling 4.

Next, the principle of preventing the furniture 2 from falling when it is slightly tilted will be illustrated with reference to FIG.

Tipping is equivalent to rotating the furniture 2 in a clockwise direction about the lower front edge 7 of the furniture 2.

The anti-fall device 3 is fixed to the upper surface of the furniture 2 by a fixing device 6 at its lower part, and the length of the support 5 is slightly longer than the distance between the upper surface of the furniture 2 and the ceiling 4 and is inclined to the right. Therefore, the force caused by the overturning of the furniture 2 is initially applied to the support 5 in the direction of its inclination. This pressing force is divided into a force that causes the support end 51 to slide to the right against the frictional force with the ceiling surface, and a force that presses the ceiling 4, and the magnitude of both is determined by the slope of the support 5. The closer the angle is to the vertical, the smaller the force is on the support end 51 to the right, so it is less likely that it will actually slip, and in the end, the support 5 will move against the furniture 2 in the opposite direction to the falling direction. It rotates in the counterclockwise direction and presses against the ceiling 4.

This pressing continues until the support 5 becomes perpendicular to the ceiling surface, but the length of the support 5 itself is longer than the distance between the top surface of the furniture 2 and the ceiling 4 before the furniture 2 falls, and Considering that the distance is getting smaller and that there is a limit to the deflection of the ceiling and the top of the furniture, it is unlikely that the support 5 will continue to be perpendicular to the ceiling, and it will probably fall over (furniture). It will stop at the very early stage of rotation 2).

Furthermore, if the force that causes the furniture 2 to fall (rotate the furniture 2) is released, the furniture 2 will rotate counterclockwise due to its own gravity and return to its original position. Since the body 5 is also inclined in the opposite direction to the counterclockwise rotation, the end 51 will slide on the ceiling surface and return to its original position without pressing the ceiling surface.

This device is especially effective in cases where the force that causes the furniture to fall (rotation of the furniture 2) is applied and released in small increments, such as vibrations caused by an earthquake. In other words, the fall prevention device 3 normally covers the ceiling 4 as well as the furniture 2.
Since the prevention force is activated only when the furniture starts to fall (rotation of the furniture 2) because the furniture 2 is not pressed too hard, even if the support 5 oscillates at a slight angle, the tools will not shift. It is hard to imagine that the effect would be reduced. for,
With conventional fall prevention using nails and fasteners, vibration means a decline in effectiveness, and if the furniture vibrates, it will never strengthen naturally and you will immediately worry about nails falling out. It is something that must be done. Such conventional fall prevention methods are extremely inferior as earthquake countermeasures.

Next, a method for preventing the furniture 2 from falling over when it is not close to a wall, such as in so-called partition furniture, will be described.

FIG. 2 shows a case where the furniture 2 is placed singly (or in one row). In this case, there are two possible directions for the fall, so the support 5
Also, as shown in FIG. 1, there is a need for something that is tilted not only in one direction but also in the opposite direction. The principle of fall prevention is the same as the explanation given in accordance with FIG.

In addition, when the furniture 2 is placed back to back (Fig. 3), the fall prevention devices 3 are placed so that the supports 5 are tilted outward from each other on the upper surface of each piece of furniture 2 as shown in the figure. It would be sufficient to fix .... Then, if furniture 2... begins to rotate to the right, the fall prevention device 3 on the right side will stop both pieces of furniture 2... from rotating, and conversely, if furniture 2... starts to rotate to the left, the fall prevention device 3 on the left side will stop the rotation of both pieces of furniture 2... 3 will stop the rotation of furniture 2... on both sides.

However, in the above explanation, if there is wall 1, support 5
It states that it is sufficient if the slope is only in one direction, and that it is necessary to slope in two directions. It is of course possible to install fall prevention devices with two types of inclinations, such as the above, or more than two types.

FIG. 4 shows one of the fall prevention devices 3 used in the present invention.
This is an example. The support body 5 and the fixture 6 are rotatably connected by a support pin. Also,
The spring 8 is adapted to press the support 5 against the ceiling surface during installation. A rubber member is attached to the end 51 of the support 5 for the purpose of preventing slipping.

As mentioned above, the closer the inclination angle of the support 5 is to the vertical plane, the more difficult it is for the end 51 of the support 5 to slip. However, if the furniture is brought too close to the vertical plane, the support body 5 will exceed the vertical plane as soon as the furniture starts rotating, and the effect of preventing the furniture from falling will be lost. Therefore, the end 51 of the support 5 must be installed at an angle that will not cause it to slip and the length of the support 5 will be as long as possible.

In experiments conducted by the present inventor, the best effect was obtained when the support 5 was tilted at an angle of about 30 degrees with respect to the vertical. It is configured to be horizontal and close to the ceiling surface. Alternatively, this anti-slip member may be made rotatable relative to the support body 5.

Furthermore, the material of the anti-slip member does not limit the present invention.

Further, the length of the support body 5 is longer than the distance between the upper surface of the furniture 2 and the ceiling 4;
Rather than being fixed as shown in this figure, it may be one whose length can be changed freely (however, the length after changing does not change even if pressed). For example, if the end 51 shown in FIG. 5 is set to an appropriate length to slide inside the pipe, the retaining pin
Possible options include something that can be fixed with.

Further, as another example of the shape of the fall prevention device 3, there is one as shown in FIG. This means that the supports are in two directions, and in a case like the one shown in FIG. 2, two fall prevention devices can be provided with one device.

Next, the furniture 2 of the fall prevention device 3 used in the present invention
Fixing to the top surface will be briefly described. (Fig. 7) In general, the upper surface of the furniture 2 does not need to be very strong in terms of strength, so it may be made of relatively weak plywood or the like. Therefore, in order to reinforce the upper surface of furniture 2, which is easy to bend and weak,
In order to enhance the effect of fixing the fall prevention device 3 itself, it is better to install the fixing plate 10 with a length sufficient to the length of the upper surface of the furniture 2 in the width direction. Furthermore, if the shape of the fixing plate 10 is devised, for example, by making it into a rail shape so that the optimal position is obtained while sliding the fall prevention device 3, the upper surface of the furniture 2 may be damaged each time the fall prevention device 3 is removed. There will be no need to worry. However, these are additional matters to the present invention and do not limit the present invention.

As explained in detail above, the furniture fall prevention device of the present invention has a support body that is slightly longer than the distance between the top surface of the furniture and the ceiling, and is placed on the top surface of the furniture in the direction in which the furniture falls. Incline (e.g. about 30 degrees)
By fixing the furniture in place, if the furniture is about to topple over, the support will press against the ceiling to prevent it from falling over.Usually, the end of the support only lightly presses against the ceiling. Therefore, it is easy to move furniture, it does not damage the ceiling, and if it tries to fall, it will definitely prevent it from falling, so it is very useful as an earthquake countermeasure and to prevent accidents caused by children's play. This is a useful invention.
