Conventional technology and its problems Many methods have been proposed and implemented to prevent storage furniture from falling over, but all of the practical methods involve tying storage furniture to the walls or pillars of a house. It was hot. Therefore, there was a problem in that if appropriate anchoring members could not be fixed to the walls or pillars, it would not be possible to take measures to prevent falls, and if the walls or pillars were weak, a reliable effect of preventing falls could not be obtained. .

The present invention solves the problems of the conventional technology, and solves the problems in cases where the anchoring member cannot be fixed to the wall or pillar,
To provide a device that can reliably prevent a house from falling even when the walls and pillars of the house are weak.

Means for Solving the Problems The object of the present invention is to provide a horizontal flat plate part laid under the tatami mat and an upright part extending approximately vertically from the horizontal flat plate part to the lower end of the storage furniture beyond the thickness of the tatami mat. a supporting plate having a support plate extending substantially horizontally from a position above the tatami mat in the upright part to a distal end side of the horizontal flat plate part, and when the storage furniture is installed with its rear end positioned immediately in front of the upright part; a support rod having a length that passes through a through hole provided at the rear of the lower end of the storage furniture and reaches the front of the lower end of the storage furniture; and the front end of the support rod is coupled to the front end of the storage furniture. This is achieved by a device for preventing overturning of storage furniture, which is characterized by comprising a coupling portion for preventing the overturning of storage furniture.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows storage furniture A installed on a tatami mat C using the fall prevention device 1 according to the present invention.
Storage furniture A includes an architrave B at the lower end, and the architrave B is fixed to the main body of the storage unit. The fall prevention device 1 is
It includes a support plate 2, a support rod 3 and a connecting part 4. The support plate 2 is made of metal or hard synthetic resin, and includes a horizontal flat plate part 20 laid under the tatami mat,
From the horizontal flat plate part 20 to the architrave B beyond the thickness of the tatami C
It is provided with an upright portion 21 extending vertically to a height of . The horizontal flat plate part 20 extends from the upright part 21 under the tatami mat with an appropriate length, but in order to ensure prevention of falling, it is desirable that the horizontal plate part 20 be as long as the depth of the storage furniture A or longer. It is desirable that the length be approximately equivalent to the entire length. Support rod 3
is a metal rod that extends substantially horizontally from a position above the tatami in the upright portion 21 to the distal end side of the horizontal flat plate portion 20, and its base end is fixed to the upright portion 21 by welding or the like. In this example, a flange 30 is provided on the base end side to support the architrave B at a certain distance from the upright part 21, and the tip extends to the vicinity of the front inner surface of the architrave B whose rear end surface is in contact with the flange 30. The distal end thereof is provided with a threaded portion 31. Architrave B
A through hole through which the rod 3 passes is provided in the rear wall. The coupling part 4 is for fixing the tip of the rod 3 to the architrave B, and is connected to the cylinder body 40 and the set screw 4.
1, the cylindrical body 40 is provided with a female screw threaded at the rear part thereof to be screwed into the threaded part 31 at the tip of the rod, the front end surface is widened so as to contact the inner surface of the architrave B, and a set screw 41 is screwed into the central part of the cylindrical body 40. A matching internal thread is provided. The threaded portion 31 of the rod and the set screw 41 are formed to have a reverse thread relationship. The front wall of the architrave B is provided with a through hole through which a set screw 41 is passed, and the bottom plate of the storage furniture A is provided with an opening/closing portion D for attaching the connecting portion 4. Support rod 3
The connecting portions 4 can be attached at an appropriate number of locations in the frontage direction of the storage furniture, and the width of the support plate 2 is made to correspond to these locations. Preferably,
Support rods 3 and the like are attached near both ends of the storage furniture in the frontage direction. The support plate therefore has approximately the same width as the width of the frontage of the storage furniture, but it can also be divided into pieces each having one support rod. Alternatively, one support plate may be provided with support rods for a plurality of storage furniture.

In order to install storage furniture A using this fall prevention device 1, first, the support plate 2 is placed under the tatami mat on which the storage furniture is to be installed, so that the upright portion 41 is in a state protruding above the tatami mat. As shown in FIG. 1, the upright portion 21 is usually made to protrude from between the wall E of the room and the tatami mat C. In this state, the support rod 3 is
1, it extends approximately horizontally above the tatami. Next, the storage furniture A is placed in front of the support rod 3 and moved rearward so that the rod 3 passes through the through hole in the rear wall of the architrave B. After it has moved to a certain extent, open the opening/closing part D and attach the cylinder 4 to the threaded part 31 at the tip of the rod 3.
0, and then move the storage furniture A until the collar 30 comes into contact with the rear surface of the architrave B. At this time, the cylinder 4
The front end surface touches the inner surface of the architrave, but if it is far away, adjust it so that it comes into contact with the threaded part. moreover,
The set screw 41 is screwed onto the cylinder body 40 from outside the architrave B, and the installation is completed.

As a result, the storage furniture A is integrally connected to the tatami mat C via the fall prevention device 1, and is prevented from falling over due to the wide installation surface of the tatami mat C. Especially storage furniture A
Since the rear part of the storage furniture A is held by the base end of the support rod 3 and the support plate 2 so as not to separate from the tatami C, the storage furniture A is firmly supported against falling forward.
The rear side is supported by the wall E, which provides a reliable fall prevention effect. Although ordinary tatami mats have sufficient rigidity to obtain this overturning effect, an even stronger overturning effect can be obtained by increasing the bending rigidity of the horizontal flat plate portion 20.

The example shown in FIG. 2 shows a fall prevention device 1a that has a greater degree of freedom in installing storage furniture than the device shown in FIG. In FIG. 2, only the architrave B is shown as the storage furniture for simplicity. In this example, the support plate 2a has a horizontal groove 22 in the upright portion 21a rising from the horizontal flat plate portion 20a, and the support rod 3a is fitted into the horizontal groove 22 with a flange 32 at the rear end to prevent it from falling out. It is held slidably along the groove. It is desirable that the support rod 3a maintains a posture extending substantially horizontally from the upright portion 21a. For this reason, for example, the upright portion 2 cooperates with the flange 32.
A further flange narrowing 1a can be provided on the rod 3a. Therefore, according to this device 1a, the support rod 3a can be moved in the horizontal direction even after the support plate 2a is placed under the tatami mat, providing a wide degree of freedom in installing storage furniture.

In this example, the through hole b of the architrave B is lengthened in the horizontal direction, thereby further liberalizing and facilitating the installation. Of course, such a through hole b can also be applied to the example shown in FIG. The collar 30a of the rod 3a is connected with a screw, so that the position of the rod 3a can be adjusted in the axial direction. In addition to this example, the horizontal groove 22 can be formed in various ways, such as by providing angle members vertically in parallel on the upright portion to form a C-shaped cross section.

FIG. 2 also shows another example of a joint.
This connecting portion 4a is connected to a threaded portion 42 at the tip of the rod 3a.
and a nut 43 that is screwed into this. When the architrave B moves from the position shown in Fig. 2 in the direction of the arrow and comes into contact with the collar 30a, the threaded part 42 protrudes from the through hole b, and the nut 43 is screwed into this and fastened, thereby making the connection. It can be done.

The support plate is configured such that the horizontal flat plate part and the upright part have an L-shaped cross section as in each of the above examples, and the horizontal flat plate part is arranged on both sides of the upright part to form an inverted T-shaped cross section. It may be configured as follows. In this case, parallel horizontal flat plate sections are placed under two tatami mats, and the standing section is made to protrude from between them. This support plate is particularly advantageous when installing storage furniture back to back in the center of a room, etc., by connecting the lower end of the back of each storage furniture to the upright part to prevent it from falling forward. The storage furniture is mutually supported toward the rear to prevent it from falling over.

Effects of the invention As is clear from the above explanation, according to the fall prevention device for storage furniture according to the present invention, the support plate is laid with the horizontal flat plate part positioned under the tatami mat and the upright part protruding from the tatami mat, The storage furniture is connected at the front through a support rod extending substantially horizontally from the upright portion and a through hole in the lower end of the storage furniture, so that the storage furniture is in a state where the tatami mat is held between the support plate and the support rod. It is integrally connected to the tatami mat, thereby preventing it from falling over in the event of an earthquake or the like. Particularly, in the present invention, the support rod and the storage furniture are connected at the front part of the storage furniture, so that the operation thereof is facilitated.
