Description

  The present invention relates to an overturn prevention device for furniture (hereinafter referred to as furniture) such as a basket, a cupboard, and a bookshelf placed indoors. More specifically, the present invention relates to a tipping prevention device that prevents furniture from falling over when it is subjected to unexpectedly large vibration such as an earthquake.

  In general, furniture with a height such as a bag has a high center of gravity, so that there is a problem that the furniture is likely to fall down if it receives a vibration exceeding a predetermined level when an earthquake occurs. Therefore, many jigs and devices for preventing the furniture from falling have been proposed.

  For example, a fall-preventing tool in which furniture is fixed directly to a wall or the like using screws, nails or the like has been known. However, such a fall prevention tool cannot be expected to have a fall prevention effect unless the screws, nails, etc. are considerably thick and long. On the other hand, plasterboard is often used for recent walls, so screws and nails are not effective. In addition, in the case of collective housing and rental housing, it is often prohibited to make a hole in the wall itself.

  In view of this, many tension-type fall prevention devices installed between furniture and the ceiling have been proposed. With such a tension type fall prevention tool, furniture can be prevented from falling without damaging the wall or ceiling. Patent document 1 discloses the fall prevention tool (falling prevention apparatus) relevant to this. In this fall prevention device, a fixing nut is screwed to a lower end portion of a screw shaft erected from a central portion of a lower fixing base, and an adjustment nut is screwed to an intermediate portion. And the cover branch pipe is inserted by the outer part of both nuts. Further, the lower end portion of the cover branch pipe is formed in a shape that engages with the fixing nut, and an arbitrary number of adjustment branch pipes are connected to the upper side of the cover branch pipe. Furthermore, an elastic machine is interposed between the adjustment nut and the lower end of the first stage adjustment branch, and the upper end of the uppermost adjustment branch is fitted into a fixed branch projecting from the center of the upper fixed base. . Such a fall-preventing device has been proposed as a highly safe device that eliminates the drawbacks of the shaft tube being broken or the fixed portion being relaxed.

  However, when installing the overturn prevention device disclosed in Patent Document 1, it is necessary to connect a plurality of adjustment branch pipes so as to correspond to the length between the furniture and the ceiling, and finally rotate the cover branch pipe. It is necessary to adjust the length in the axial direction. Therefore, when the distance between the top plate and the ceiling is long, a large number of adjusting branch pipes are connected, so that there is a problem that installation takes labor and time and handling is poor. In addition, since the fall prevention tool has a single columnar shape, it is not possible to expect a reliable fall prevention effect simply by installing one. For this reason, since it is necessary to arrange a plurality of them at the same time, there is a problem that more labor and time are required.

  The fall preventive tool is provided with leg portions having a relatively large area at the upper and lower ends of the column portion serving as the main body. However, such a leg portion has an insufficient contact area when installed between furniture and the ceiling. Therefore, there is a possibility of falling down when it is subjected to horizontal or horizontal rolling due to an earthquake. In a situation where rolling has occurred, a plurality of fall prevention tools arranged at the same time will fall in the same manner. Therefore, a sufficient fall prevention effect cannot be expected even if a plurality of fall prevention tools are simply arranged. Therefore, a structure in which the above-mentioned overturn prevention tool is improved and two are connected can be considered. In this case, since the two fall-preventing tools are integrated, they are more resistant to rolling compared to a single case. However, when these two are arranged on the left and right, it can cope with the lateral roll, but when it is subjected to the forward and backward roll, it falls over. In order to be able to cope with both front and rear and left and right rolls, it is necessary to have a structure in which three or more are connected. This complicates the structure of the tipping prevention tool and increases the manufacturing cost. Furthermore, when the fall prevention tool having such a complicated structure is arranged on the furniture, it becomes impossible to utilize the space on the furniture that can be utilized conventionally.

  Therefore, an object of the present invention is to solve the conventional problems described above, and to provide an overturn prevention device that can easily perform installation work and can reliably prevent the furniture from falling over.

  The above-mentioned object is a fall-preventing tool for preventing the furniture from toppling, which is installed between the furniture and the ceiling, and is a flat base plate placed on the top plate of the furniture, A flat plate upper plate disposed to face the base plate and abutted against the ceiling, and a plurality of support columns connecting the base plate and the upper plate, the support column, This can be achieved by a furniture overturn prevention device that is set on the outer edge of the base plate and the top plate and is extensible.

  According to the fall prevention device of the present invention, the installation work can be completed with a simple operation of extending the support column and fixing it at an arbitrary position. Therefore, it can provide as a fall prevention tool with good installation workability. Moreover, since it is the structure which supports the flat base board and upper board which have a predetermined area with a some support pillar, it will be in the state which contacted the top plate and ceiling of furniture widely. Therefore, the fall of furniture can be prevented with certainty. In addition, since the support column is set at the outer edge, a large space can be secured on the front side for effective use.

  The support column includes a long hollow first column and a second column that is slidably inserted into the first column, and the second column is locked by a lock mechanism. It is preferable that it is formed so as to be fixed at an arbitrary position of one pillar portion.

  Moreover, it is more preferable that cushion materials having anti-slip properties and shock absorption properties are provided on the bottom surface of the base plate and the upper surface of the upper plate.

  According to the present invention, it is possible to provide an overturn prevention tool that can easily perform installation work and reliably prevent furniture from falling over.

  Hereinafter, with reference to the drawings, a fall prevention device according to an embodiment of the present invention will be described.

  FIG. 1 is a perspective view showing an appearance of the overturn prevention tool 1 of the embodiment. FIG. 2 shows a view of the overturn prevention device 1 from three directions, (A) is a plan view (top view), (B) is a front view, and (C) is a right side view. This overturn prevention tool 1 is composed of a base plate 2, an upper plate 3, and two support columns 4 and 5 that connect them with a gap.

  The base plate 2 and the upper plate 3 are formed of a flat plate member, and the approximate shape is a rectangular shape. The material used for the base plate 2 and the upper plate 3 is not particularly limited as long as it has a certain level of rigidity, but a resin plate, a metal plate, or the like can be used. When a metal plate material is used, an aluminum material is preferable from the viewpoint of ease of handling and strength. The base plate 2 and the upper plate 3 may be formed of the same material or different materials.

  The base plate 2 and the upper plate 3 are disposed so as to face each other with support columns 4 and 5 interposed therebetween. The base plate 2 is placed on a furniture top plate 101 (not shown). On the other hand, the upper plate 3 is set so that the upper surface 3UP comes into contact with the indoor ceiling CE. The support columns 4 and 5 are designed to be stretchable. Therefore, the distance (height) H between the base plate 2 and the upper plate 3 is adjusted by the support columns 4 and 5. As for the support pillars 4 and 5, an aluminum material can be suitably employed as in the case of the base plate 2 and the upper plate 3.

  Each support column 4 and 5 has the same structure. For example, each of the support columns 4 and 5 includes a first column portion 41 and 51 and a second column portion 42 and 52. The first column parts 41 and 51 are long and hollow, and are erected and fixed on the base plate 2. Similarly, long second column portions 42 and 52 are slidably inserted into the first column portions 41 and 51. The upper ends of the second pillar portions 42 and 52 are fixed to the lower surface of the upper plate 3. An insert nut is embedded in each end of the support columns 4 and 5. The base plate 2 and the upper plate 3 are fixed by screwing screws 8 into the insert nuts.

  The second column portions 42 and 52 can be fixed to arbitrary positions of the first column portions 41 and 51 by the lock mechanisms 6 and 7. As the lock mechanisms 6 and 7, conventionally known ones can be widely used. For example, a structure in which the second column parts 42 and 52 are fastened to the first column parts 41 and 51 by a toggle mechanism (a boost mechanism) and fixed. Can be adopted. The lock mechanisms 6 and 7 employed in the present embodiment release the tightening force when the levers 61 and 71 are opened, and generate a strong tightening force when the levers 61 and 71 are closed. FIGS. 1 and 2 illustrate a state in which the lever is closed and a tightening force is generated to fix the second pillar portions 42 and 52 to the first pillar portions 41 and 51.

  The lengths of the first column parts 41 and 51 and the lengths of the second column parts 42 and 52 are set to be substantially the same. If it sets in this way, it will become the height of the 1st pillar part 41 and 51 or the 2nd pillar part 42 and 52 when it shrinks most, and when it is fully extended, it can be set as twice that height. Therefore, the distance between the base plate 2 and the upper plate 3 can be adjusted in a wide range corresponding to the distance between the furniture and the ceiling. 2B and 2C show the state when the position of the upper plate 3 is moved by broken lines.

  The support columns 4 and 5 are disposed on the outer edges of the base plate 2 and the upper plate 3 which are rectangular. Therefore, when the fall prevention tool 1 is installed between the furniture and the ceiling, a space that can be utilized between the base plate 2 and the upper plate 3 can be secured. In the illustrated example, the case where two support columns 4 and 5 are arranged is illustrated, but three or more support columns may be provided. Also in this case, it is preferable to arrange at the outer edge so as to ensure a central space.

  In addition, it is preferable to arrange | position the cushioning material 10 provided with the slip prevention property and the shock absorption property to the bottom face 2BT of the base board 2, and the upper surface 3UP of the upper board 3 as shown in the figure. If such a cushioning material is provided, it is possible to prevent the tipping prevention tool 1 from being displaced from the set position, so that the furniture can be surely toppled without being displaced due to slight vibrations caused by an earthquake. Can be prevented. As the cushion material 10, a sheet-like vibration-proof rubber, a silicon material, or the like can be suitably used. In the illustrated example, the cushion material 10 is provided on both sides, but it may be provided on the entire bottom surface 2BT and the entire top surface 3UP. Further, when the cushion material 10 is disposed only on both sides as shown in the drawing, the thickness of the base plate 2 and the upper plate 3 is reduced when the installation is performed by generating a tension force as described later, and the entire surface of the base plate 2 and the upper plate 3 are the furniture and You may set the thickness of the cushioning material 10 so that it may contact a ceiling. By setting in this way, a wide contact area can be secured even if a cushion material is provided in part.

  The fall prevention tool 1 having the above configuration is used as follows. This will be described with reference to FIG. FIG. 3 is a view showing a state when the fall prevention device 1 is installed between the furniture and the ceiling, (A) is a view showing a state of installation from the front, and (B) is a view from the left side. It is the figure which showed the mode of.

  When using the fall prevention tool 1, the base plate 2 is placed on the top plate of the furniture 100. In that case, the fall prevention tool 1 is pushed into the center back side so that the support columns 4 and 5 are on the rear side. As shown in the figure, when the wall WA is on the back of the furniture 100, the support columns 4 and 5 are arranged along the surface of the wall WA. Thereafter, the levers of the lock mechanisms 6 and 7 are loosened, the second pillar portions 42 and 52 are extended upward, and the levers of the lock mechanisms 6 and 7 are closed and fixed in a state where the upper plate 3 is in contact with the ceiling CE. Thereby, the fall prevention tool 1 can be installed between the furniture 100 and the ceiling CE in a state where a tension force is applied.

  The fall prevention tool 1 of the present embodiment having the above-described configuration is a simple operation in which the levers of the lock mechanisms 6 and 7 are loosened, the second pillar portions 42 and 52 are extended upward, and the levers are closed and fixed. Can complete the installation work. Therefore, it can provide as a fall prevention tool with good installation workability. In addition, since the base plate 2 and the upper plate 3 having a predetermined area are supported by the plurality of support pillars 4 and 5, the base plate 2 and the ceiling CE of the furniture 100 are in wide contact with each other. Therefore, since the fall prevention tool 1 of the present embodiment can deal not only with vertical shaking but also with horizontal and horizontal rolls, it is possible to reliably fall furniture without having to install a plurality of them. Can be prevented. Further, since the support columns 4 and 5 are set at the outer edge portion, a large space SP can be secured on the front side as shown in FIG. Therefore, the upper part of the furniture 100 can be utilized as a storage space as in the conventional case.

  Furthermore, the fall prevention tool 1 of the present embodiment is provided with a cushioning material having anti-slip properties and shock absorption properties on the bottom surface of the base plate 2 and the upper surface of the upper plate 3. Therefore, since it can prevent shifting from the position once installed, the fall of furniture 100 can be prevented more reliably.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and within the scope of the present invention described in the claims of the utility model registration, Various modifications and changes are possible.
