Description

  The present invention relates to a technique for preventing stored furniture from falling down due to an earthquake or the like.

  Conventionally, the support plate provided at the lower end of the strut body is placed on the top plate of the storage furniture, and the abutment portion of the upper end portion of the strut body abuts against the ceiling so that the storage furniture does not fall down during an earthquake. This is known from Patent Document 1 and the like.

  By the way, in the storage furniture 3, when the side plate 1 and the top plate 2 are joined, the bottom surface of the top plate 2 is placed and joined to the upper end surface of the side plate 1, and the inner surface of the opposing side plate 1 is joined. There are some which are installed between the upper end portions and join the side end surface of the top plate 2 and the inner side surface of the side plate 1, but the former is not so preferable because the side end surface (the end) of the top plate 2 is exposed. Is installed between the upper end portions of the inner side surfaces of the opposing side plate 1 so that the side end surface (the end) of the top plate 2 is not exposed, and the side end surface of the top plate 2 and the inner side surface of the side plate 1 are joined. ing.

In the storage furniture 3 having a structure in which the side end surface of the top plate 2 and the inner side surface of the side plate 1 are joined as described above, the support plate at the lower end of the projecting body 6 ′ is stored as shown in FIGS. 6 (a) and 6 (b). In the case where the top plate 2 of the furniture 3 is placed on the top plate 2 and the abutment portion at the upper end is in contact with the ceiling to prevent a fall during an earthquake, a large load is applied to the top plate 2 from the projecting body 6 '. In this case, the joint portion between the side end surface of the top plate 2 and the inner surface of the side plate 1 is easily damaged. For this reason, due to the load applied to the top plate 2 from the strut 6 'during an earthquake, a load is applied to the joint between the side end surface of the top plate 2 and the inner surface of the side plate 1, and the top plate 2 as shown in FIG. However, there is a problem that the storage furniture 3 falls down from the side plate 1.

  The present invention has been invented in view of the above-described conventional problems, and even if a load is applied to the storage furniture from the strut body during an earthquake, the joint between the top plate and the side plate does not come off, and the storage furniture is reliably It is an object of the present invention to provide a storage furniture fixing structure that can prevent overturning.

  In order to solve the above problems, a storage furniture fixing structure according to the present invention comprises storage furniture 3 in which a top plate 2 is installed between upper ends of inner side surfaces of opposing side plates 1, and a plurality of storage furniture 3 is connected to the side plate. Are arranged side by side so that they are in contact with each other, and in the adjacent portion of the storage furniture 3, the insertion notches 4 are respectively provided at the side end portions on the adjacent sides of the top plates 2 of the adjacent storage furniture 3. A fitting portion 7 is provided at the lower portion of the projecting body 6 for contacting the inner surface of the projecting body 6, and the fitting portion 7 is formed in a U-shaped cross section with a pair of leg portions 7a extending downward from the upper connecting horizontal piece portion 7b. The pair of leg portions 7a are inserted into the insertion notches 4 provided at the side end portions of the top plate 2 of the storage furniture 3 adjacent to each other from the upper side to the inner side surfaces of the side plates 1 of the storage furniture 3 adjacent to each other. The upper connecting horizontal piece 7b is fixed to the upper end surface of the adjacent side plate 1 while being fixed by the fixing tool 8 along the side. It is characterized in that formed by setting.

  With such a configuration, the pair of leg portions 7a is fixed to the inner side surface of the adjacent side plate 1 with the fixing tool 8 in a state where the upper connecting horizontal piece portion 7b is placed on the upper end surface of the adjacent side plate 1. The load applied to the storage furniture 3 from the brace 6 during an earthquake can be directly transmitted from the upper connecting lateral piece 7b to the upper end surfaces of the two side plates 1 that are in contact with each other, and the pair of leg portions 7a are connected to the both side plates 1 This prevents the phenomenon that the load is concentrated on the top plate 2 as in the prior art and the joint between the side end surface of the top plate 2 and the inner side surface of the side plate 1 is disconnected. In the event of an earthquake, it is possible to reliably prevent the storage furniture 3 from being overturned by the struts 6 and to fix the leg portions 7a to the inner side surfaces of the adjacent side plates 1 so that the leg portions 7a do not get in the way. Further, the side plates 1 of the storage furniture 3 adjacent to each other are sandwiched and connected by the fitting portion 7 having a U-shaped cross section, and the storage furniture 3 is less likely to fall than the case of the single storage furniture 3. Furthermore, since the projecting body 6 is fixed to the storage furniture 3, the position of the projecting body 6 does not occur, and there is no fear that the projecting body 6 will come off the storage furniture 3 due to vibration during an earthquake. 3 can be prevented from falling.

  Moreover, it is preferable that the tension member 6 is adjustable in height.

The bottom plate is constructed between the lower end portions of the inner surfaces of the left and right opposing side plates 1, so that the top plate 2 and the side plate of the bottom plate are not exposed to the outside. ing. At the side end of the top plate 2 on the side plate 1 side, there are provided a U-shaped outer side that is U-shaped in plan view and an insertion notch 4 that opens up and down, and the side plate is located at the outer opening of the insertion notch 4. The inner surface of 1 is located. In addition, a back plate is provided on the back of the storage furniture 3 as necessary, and a partition, a shelf, a drawer, and the like are provided in the interior as needed.

  The strut 6 is made of metal, and is configured by providing a fitting portion 7 at a lower portion of a column portion 9 having a ceiling contact portion 10 at an upper end portion.

  The fitting portion 7 provided in the lower portion of the projecting body 6 is formed in a U-shaped cross section in which a pair of vertical plate-like leg portions 7a are provided below the upper connecting horizontal piece portion 7b. The column portion 9 protrudes upward from the center of the upper surface of the upper connecting lateral piece 7b of the fitting portion 7.

  An insertion hole 11 is provided in the leg portion 7a.

  In order to fix the storage furniture 3 using the tension member 6 having the above-described configuration, the following procedure is performed.

  That is, the storage furniture 3 is installed on a plurality of floors and arranged side by side in the left-right direction so that the side plates 1 come into contact with each other. In this case, the side end of the top plate 2 is aligned in the left-right direction via the two side plates 1 with which the insertion cutout portions 4 provided at the side end portions of the top plate 2 of the adjacent storage furniture 3 are in contact. The notch position of the insertion notch part 4 is set in the part.
