Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for reliably preventing 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, block walls would fall, all large furniture in homes would topple over, etc., 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. There have been a number of accidents in which people have fallen over and been crushed under the furniture, causing 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 Be careful not to do this aggressively, as it may damage walls and ceilings.Also, in the unlikely event that furniture begins to fall due to children's play or an earthquake, the initial vibrations It would be completely meaningless if it came off or broke, and it was troublesome to remove the nails when removing the preventer itself due to moving furniture, etc.

In addition, recently we have seen many condominiums with large floors, such as one-floor apartments, but in such places, the rooms are often partitioned with tall furniture, and the only place to secure such furniture is the ceiling. Under the conventional law, the fixation was likely to be overseas.

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.
In addition, he invented a method for preventing furniture from falling over, which does not damage furniture or ceilings, and allows for easy attachment and detachment of equipment.

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

Figure 1 (al and (bl) shows a method of preventing furniture (2) from falling over according to the present invention in a situation where furniture (2) is placed against a wall (11). Furniture (2) does not tip over to the left side because there is a wall +1.1 on the left side.Furniture (2), such as a chest of drawers, that is usually installed next to a wall is long in the direction of the wall and narrow in width. Therefore, it can be said that the risk of falling is toward the right side in the figure, or in other words, in a clockwise direction.

Therefore, the fall prevention device (3) is first fixed to the upper surface of the furniture (2). This fall prevention device (3) is attached to a support (5) slightly apart from the distance between the top of the house (2) and the ceiling (4), and the support (5) is fixed to the top of the furniture (2). It consists of a fixture (6), and its installation is done by placing the support (5) near the wall.
) is performed so that the furniture (2) is tilted in the direction in which it falls.

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

Next, the principle of preventing the furniture (2) from tipping over when it is slightly tilted is shown in the figure (bl).

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

The fall prevention device (3) is fixed to the top surface of the furniture (2) by the fixing device (6) at the bottom thereof, and the length of the support body (5) is the distance between the top surface of the furniture (2) and the ceiling (4). Since it is slightly longer and inclined to the right, the force caused by the overturning of the furniture (2) will initially be applied to the support (5) in the direction of its inclination. This pressing force is divided into the force that causes the support end # (51) to slide to the right against the frictional force with the ceiling surface, and the force that presses the ceiling +41. The closer the inclination angle of 5) is to the vertical, the smaller the force is on the end of the support (51) to the right, so it will not actually slide. (2), it rotates counterclockwise, which is the opposite direction to the falling direction, and presses against the ceiling (4).

This pressing continues until the support (5) is perpendicular to the ceiling surface, but the length of the support (5) itself is furniture + 21
Considering that the distance between the top of the furniture (2) and the ceiling (4) is greater than the distance before the fall, that this distance decreases as the furniture falls, and that there is a limit to the deflection of the ceiling and the top of the furniture, the support It does not continue until the body (5) is perpendicular to the ceiling surface, and it is likely that the body (5) will fall (furniture (2)
) will stop at the initial stage of rotation.

Furthermore, if the force that causes the furniture to fall (rotation of the furniture (2)) is released, the furniture (2) will rotate counterclockwise due to its own gravity and return to its original position.
The support body (5) in 3) is also tilted in the opposite direction to the counterclockwise rotation, so it can be rotated at the end (5) without pressing the ceiling surface.
1) V; J It will slide on the ceiling surface and return to its original position.

This method is particularly 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. 5) It prevents falls by weakening the force that tries to prevent the slope from approaching vertical, in other words, it is usually used as a fall prevention device (3)
is not pressing strongly against either the ceiling (4) or the furniture (2), and the force that prevents it is applied only when the furniture starts to fall (rotation of the furniture (2)). ), it is hard to imagine that even if the tool is angularly vibrated at a slight angle, the tool will shift and its effectiveness will decrease. On the other hand, with conventional fall prevention using nails and fasteners, vibration means a decline in effectiveness; if the furniture vibrates, it will never be strengthened naturally, and the nails will immediately become weaker. The idea is that we have to worry about losing friends. Such conventional fall prevention methods are extremely inferior as earthquake countermeasures.

Next, a method for preventing 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, since there are two directions in which there is a possibility of overturning, the support (5) needs to be inclined not only in one direction as shown in FIG. 1, but also in the opposite direction. Note that the principle of fall prevention is the same as the explanation given in accordance with FIG.

Also, when the furniture (2) is placed back to back (Fig. 3), each support (5) is placed on the top surface of each piece of furniture (2), facing outward from each other, as shown in the figure. It is only necessary to fix the fall prevention device (3) so that it is tilted. Then, when furniture (2)... begins to rotate to the right, the fall prevention device (3) on the right side stops both pieces of furniture (2)... from rotating, and conversely, furniture (2)... If it starts to rotate to the left, the fall prevention device (3) on the left side will stop both pieces of furniture (2)... from rotating.

However, in the above explanation, if there is a wall full, the support (5)
It is sufficient if the slope of is only in one direction, otherwise it is 2
It states that the direction is necessary, and even if a fall prevention device with two types of slopes as shown in Fig. 2 is placed on the - side of the furniture that is in contact with the wall as shown in Fig. 1, That's fine, of course it doesn't matter if it's longer than that.

FIG. 4 shows an example of the fall prevention device (3) used in the present invention. The support body (5) and the fixture (6) are rotatably connected by a support pin. In addition, 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 gets too close to the vertical, as soon as the furniture starts rotating,
) will exceed the vertical plane, and the fall prevention effect will be lost. Therefore, the end (51) of the support (5) will not be on the shoulder, and the length of the support (5) will be as short as possible.
It must be installed to obtain an angle that falls within the J area.

In the inventor's experiments, the best effect was obtained when the support (5) was tilted at an angle of about 30 degrees to the vertical when installed, so the length of the support (5) should be adjusted so that the end surface of the support (5) has this slope. When installed, it is configured so that it is horizontal and tightly adheres to the ceiling surface. Alternatively, the anti-slip member may be rotatable relative to the support (5).

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

In addition, the length of the support (5) is the same as that between the top surface of the furniture (2) and the ceiling (4).
), but this is also not a fixed one as shown in this figure, but one whose length can be changed freely (however, the length after changing will not change even if you press it). For example, the end (51) as shown in Fig. 5, which slides inside the pipe, can be fixed with a retaining pin +91 once set to an appropriate length.

Further, as another example of the shape of the fall prevention device (3), there is one as shown in FIG. 6. 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
” We will briefly discuss fixing to two surfaces. (Fig. 7) Generally, furniture (21-sided) does not need to be very strong in terms of strength, so it is sometimes made of relatively weak plywood.Therefore, such flexible and weak furniture (2) In order to reinforce the top surface and to increase the effect of fixing the fall prevention device (3) itself, it is better to install a fixing plate (10) with a length that is equal to the length of the top surface of the furniture (2) in the width direction. Good.Furthermore, if the shape of the fixing plate (1) is modified, for example, by making it into a rail shape and sliding the two shells (3) of the fall prevention 11 to obtain the optimal position, the fall prevention device (
There is no need to worry about damaging the top surface of the furniture (2) every time the furniture (3) is removed. However, these are additional matters to the present invention and do not limit the present invention.

As explained in detail below, the method for preventing furniture from falling according to the present invention is such that a support slightly longer than the distance between the top surface of the furniture and the ceiling is placed on the top surface of the furniture. By fixing the furniture at an angle (for example, about 30 degrees) in the direction in which it will fall, once the furniture is about to fall,
The support presses against the ceiling to prevent it from falling over, and the end of the support usually only lightly presses against the ceiling, making it easy to move the furniture without damaging the ceiling. , and since it reliably prevents the device from falling over, it is a very useful invention both as an earthquake countermeasure and as a device for preventing accidents caused by children's play.
