Description

  The present invention protects and protects furniture such as bookshelves, cupboards, baskets, lockers, etc. so that they will not fall over in the event of an earthquake, as well as other furniture, which itself functions as furniture. It relates to earthquake-resistant furniture equipped with.

  In general, the height of furniture on the floor, such as bookshelves, cupboards, bags, lockers, etc., is standardized to about 180 cm. Therefore, when arranged indoors, a gap of about 60 cm is generated between the ceiling having a height of about 240 cm, and this gap is a dead space.

  In addition, various items are often placed on the top of furniture using this gap. In this case, when an earthquake occurs, these objects fall and cause unexpected injury. In some cases, there is a problem that the furniture itself collapses and causes further damage.

  Therefore, it was necessary to take measures to prevent items placed on the furniture from falling or falling down during the earthquake.

  Conventionally, furniture is prevented from falling down on a top plate of a box-like content storage body such as furniture by four leg-shaped expansion devices and a top plate supported by the expansion device. Some were provided with seismic structures. This seismic structure portion functions to prevent the fall by pushing the upper end against the ceiling and stretching the storage body between the floor and the ceiling by the action of the telescopic device. (For example, refer to Patent Document 1).

In addition to this, install storage pipes at the inner corners of both ends of the stacked furniture placed on the top of the chest, and press the portal pipe inserted into the storage pipe from the top against the ceiling. Thus, there was also one that prevented the fall of the chiffon in the same manner as described above. (For example, refer to Patent Document 2).
JP-A-8-252136 (page 4-6, FIG. 1) Japanese Unexamined Patent Publication No. 2000-316657 (second page, FIG. 1)

  Among the conventional ones described above, the former with the earthquake-resistant structure part on the furniture must have the lower end of the leg-shaped telescopic device fixed on the top plate of the furniture. There was a risk that it would fall off the furniture and stop functioning. However, in the case of high-quality furniture that wants to prevent damage from earthquakes in particular, fixing it will be damaged because the top plate will be damaged, and it is difficult to use it so that it can perform its predetermined function easily. was there.

  In addition, this seismic structure part only functions to prevent the furniture from falling, and does not have a function to prevent the articles placed on the furniture top plate from falling.

  In addition, since the articles using the latter stacked furniture can store articles in the stacked furniture, these articles are not immediately dropped in the event of an earthquake, but the part that contacts the ceiling is thin. Since it is limited to shaped pipes, when an earthquake occurs, there is a risk of excessive stress concentrating on a specific part of the ceiling where the gate shaped pipe touches, especially on many ceilings finished with gypsum boards. In this case, the ceiling surface is easily destroyed, and this also has a problem that it is difficult to perform a predetermined function.

  In addition, the above-mentioned conventional products have the same height as the ceiling surface by placing an earthquake-resistant structure part and stacked furniture above the furniture, so that they cannot physically fall over in the same size space. However, the movement in the lateral direction is weak, and there is a possibility that the furniture slides and moves on the floor surface in the event of an earthquake. It had the problem that it might cause.

  An object of the present invention is to solve the problems of the conventional earthquake-resistant structure of furniture and the earthquake-resistant furniture.

  In order to solve the above-mentioned problems, the invention according to claim 1 of the present invention is characterized in that left and right side plates having a length approximately equal to a dimension from a floor surface on which furniture is installed to a ceiling surface, The top plate that connects the upper part of the side plates in the horizontal direction forms a front-view, substantially gate-shaped earthquake-resistant structure, and this earthquake-resistant structure is installed so as to surround the furniture, so that it will not fall over in the event of an earthquake. It is characterized by giving the furniture earthquake resistance.

  The invention according to claim 2 is characterized in that the seismic furniture installed so as to surround the side surface and the upper surface of the other furniture has left and right side plates having a length substantially equal to the dimension from the floor surface on which the furniture is installed to the ceiling surface. A box comprising a top plate and a bottom plate, which are connected to predetermined positions of the left and right side plates in the horizontal direction, and a back plate and a door provided on the back side and the front side between the top plate and the side plate. It was decided to give the furniture earthquake resistance so that it would not fall over in the event of an earthquake by protecting the furniture with this earthquake resistant furniture.

  In the invention according to the first aspect of the present invention, since the furniture is housed and protected by the gate-shaped earthquake-resistant structure having a height up to the ceiling, the furniture is not damaged at all. Can withstand earthquakes. Therefore, there is an effect that an accident caused by the furniture falling down in the event of an earthquake is prevented. In addition, the top plate that connects the left and right side plates protects the upper surface of the furniture and also functions as a storage shelf, which has the effect of effectively using the dead space on the furniture.

  In the invention described in claim 2, since the furniture is housed and protected by the gate-shaped seismic furniture having a height up to the ceiling and provided with a storage portion provided with an opening / closing door in the upper part, In addition to the effect of the invention described in Item 1, the articles stored in the storage unit are prevented from being immediately dropped in the event of an earthquake by the open / close door provided on the front thereof, thereby further improving safety. I can be taken. In addition, since the articles stored using the dead space on the furniture are concealed by the opening / closing door so as not to be visually recognized from the outside, the appearance of the article is improved.

  Hereinafter, the present invention will be described in detail based on illustrated embodiments.

  FIG. 1 is a front view showing an installation state of an earthquake-resistant structure according to the present invention, and FIG. 2 is a left side view thereof.

  As shown in the figure, the seismic structure 1 according to the present invention has an upper portion of the left and right side plates 2 and 3 having a length substantially equal to the height of the ceiling R and is connected to the upper and lower top plates 4 and 5 in the lateral direction. It is of a portal shape, and furniture such as a cupboard 20 is stored in a space formed below the lower top plate 5. Accordingly, the inner dimension between the left and right side plates 2 and 3 is set to be approximately equal to the width of the furniture (cupboard 20) to be stored, and the back surface of the lower top plate 5 and the seismic structure 1 are installed. The distance from the floor surface F is set to a dimension substantially equal to the height of the furniture (cupboard 20) to be stored.

  The side plates 2 and 3 and the top plates 4 and 5 are strong enough to be not easily bent or damaged, and are firmly and integrally connected so as not to be easily bent. The material may be any material such as plywood or steel. Moreover, the shape does not necessarily need to be a single plate-like shape. For example, the shape of the periphery may be a frame, and a punching metal or a steel net may be attached inside.

  The seismic structure 1 of the present invention has the above-described configuration.

  In addition, the code | symbol 6 in FIG. 1 shows the partition plate attached to the middle of the upper and lower top plates 4 and 5. FIG. Although this partition plate 6 is not necessarily required, if the upper and lower top plates 4 and 5 are connected by the partition plate 6 in this way, the rigidity of the earthquake-resistant structure 1 itself is improved. ,desirable. Although not shown, if further improvement in rigidity is required, the left and right side plates 2 and 3 are connected to each other on the back side (left side in FIG. 2) using a back plate or a connecting member. Also good.

  Next, the function of the seismic structure 1 of the present invention having the above configuration will be described.

  First, in a normal installation state, the cupboard 20 is stored in the internal space of the earthquake-resistant structure 1 so that the upper surface and the side surface thereof are surrounded. At this time, the gap between the periphery of the cupboard 20 and the earthquake-resistant structure 1 is set to be extremely narrow. However, the cupboard 20 is not connected to the seismic structure 1 by any means, and therefore no damage is caused by fixing metal fittings or screws. Moreover, even if the seismic structure 1 is set, the front surface of the cupboard 20 is all open, so that no problem is caused in normal use. 5 is used as a storage shelf, and the space on the cupboard 20 is effectively used.

  When an earthquake occurs in this state, as shown in FIG. 5, when the cupboard 20 is merely placed on the floor F, only the wall W on the back side (the back side of the paper in FIG. 5) There is nothing to support the cupboard 20, and therefore the cupboard 20 easily falls forward. However, when the earthquake-resistant structure 1 is set, the earthquake-resistant structure 1 has a height almost equal to the height to the ceiling R. Therefore, it is restricted by the ceiling R surface and cannot fall down. In other words, in order to fall down, a distance of at least the diagonal dimension of the side plates 2 and 3 must be generated between the floor surface F and the ceiling R surface, but the ceiling R may fall in an earthquake. However, it is unthinkable that the ceiling R is lifted. Therefore, it is impossible that the seismic structure 1 falls physically. Therefore, the cupboard 20 whose upper surface and side surfaces are regulated by the side plates 2 and 3 and the top plate 5 of the earthquake resistant structure 1 will not fall down unless it slides straight forward from the storage portion.

  In addition, since the clearance gap between the circumference | surroundings of this cupboard 20 and the earthquake-resistant structure 1 is set very narrow as mentioned above, it receives the irregular shaking at the time of an earthquake, and the cupboard 20 becomes an earthquake-resistant structure. It is difficult to think that it will slide straight forward without being caught by 1, and the fall of the cupboard 20 is almost certainly prevented by this seismic structure 1.

  The seismic structure 1 of the present invention is used and functions as described above.

  In the illustrated embodiment, the upper parts of the left and right side plates 2 and 3 are connected by the upper and lower two top plates 4 and 5. However, the top plates 4 and 5 are the left and right side plates 2 and 3. The gate-shaped seismic structure 1 may be configured by connecting the two, and the number thereof is arbitrary.

  3 and 4 show another embodiment of the present invention. In this case, a box-shaped storage portion 18 having an opening / closing door 17 provided on the front surface is provided on the left and right side plates 12 and 13, and a bookshelf is provided. The structure itself that protects 20 from falling down is the earthquake-resistant furniture 11. Therefore, the bottom plate 15 of the storage unit 18 faces the upper portion of the book shelf 20, and the book shelf 30 is restricted from being overturned by the bottom plate 15. Further, the upper surface of the storage unit 18 is closed by a top plate 14 connecting the upper ends of the left and right side plates 12 and 13, and the back surface (left surface in FIG. 4) of the storage unit 18 is closed by a back plate 19. . Thus, the basic configuration and function of this embodiment are not different from those of the above embodiment. Therefore, the detailed movement of the bookshelf 30 that cannot be overturned during an earthquake will be omitted here.

  In addition, the state where the bookshelf 30 housed and protected in the earthquake-resistant furniture 11 is installed alone is as shown in FIG. 5, and if this is also subjected to the shaking of the earthquake, the fall is inevitable.

It is a front view of the installation state by embodiment of the earthquake-resistant structure which concerns on this invention. It is a left view of FIG. It is the front view which showed the installation state of other embodiment. FIG. 4 is a left side view of FIG. 3. It is the front view which showed the independent installation state of the furniture by which storage protection is carried out.
