Description

  The present invention relates to a fixture for fixing furniture to a wall, a fixing method using the fixture, and a fall prevention structure in order to prevent indoor furniture from falling over when an earthquake occurs.

  When a large earthquake occurs, the furniture placed in the room falls and moves, and people and goods are injured and damaged. For this reason, as a measure for preventing the furniture from falling down, for example, a method of fixing the furniture to the wall surface with a fixture such as an L-shaped metal fitting or a wire is generally used. However, these methods have to fix the metal fittings and wires to the furniture with screws or nails, and damage the furniture.

  Non-Patent Document 1 discloses a method of fixing an L-shaped hardware to furniture and a wall surface via viscoelastic bodies as a method that can withstand strong earthquakes and not damage furniture.

Takeshi Sakoda and three others, “A shaking table experiment of furniture with a viscoelastic body attached to a metal fitting to prevent falling”, Summary of Annual Conference of Architectural Institute of Japan, September 2005, p. 113-114

  However, in the case of the method of attaching hardware to the upper surface of the wall and furniture or the lower surface of the floor and furniture via the viscoelastic body disclosed in Non-Patent Document 1, there is no problem on the furniture fixing side, but the wall fixing On the side, there is a problem that the above-mentioned hardware is easily detached from the wall surface because the wallpaper stuck on the wall surface is pulled by the viscoelastic body and peeled off. In addition, when a hardware is attached to the floor and the lower surface of the furniture via a viscoelastic body, there is a problem that the floor is lifted up and there is a risk of furniture falling.

  An object of the present invention is to provide a furniture fixing structure, a fixing tool, and a fixing method that can be easily fixed to a wall without damaging the furniture and that can withstand strong vibrations. is there.

The furniture overturn prevention fixture of the present invention comprises a flat resin plate or metal plate in which a back support portion for supporting the back surface of the furniture and a wall surface fixing portion fixed to the wall surface are continuously formed. The part is connected only to the furniture and only the wall surface fixing part is connected to the wall surface. Through the wall fixing part, a screw or a nail which is formed in the vertical direction and fastens the wall fixing part to the wall surface is passed. A plurality of long holes are formed in the vertical direction at a predetermined interval, a resin plate or a metal plate is bent at a right angle to form a back surface support portion and a top surface support portion, and the top long hole of the wall surface fixing portion Is characterized in that it is positioned below a predetermined distance from the bent portion so that the back surface support portion positioned on the upper surface support portion side of the elongated hole can be elastically deformed .

  According to the present invention, since the furniture is prevented from tipping mainly using the back surface of the furniture, the fixing portion is not conspicuous. Moreover, since it is a back surface, the adhesion area of a viscoelastic member can be taken widely, the effect which suppresses the vibration of furniture can be heightened, and the fall prevention effect of furniture can be heightened. Further, by fixing the furniture on any one of the top, side and bottom surfaces of the furniture in addition to the back surface, the vibration suppressing effect is exerted in any direction, and the furniture overturning preventing effect is high.

The fixture of the present invention only needs to bend a resin plate or a metal plate to form a hole for fixing the wall surface, so it can be manufactured at a very low cost, and viscoelastic members necessary for fixing furniture are also commercially available. Therefore, furniture can be fixed at a low cost. In addition, the furniture can be fixed without scratching and can be easily removed.

  In addition, by positioning the uppermost slot in the upper part of the wall fixing part at a predetermined distance from the bent part, the upper part of the back support part that is not fixed to the wall against the shaking of the earthquake is slightly like a spring By trembling, the furniture shakes energy and absorbs vibrations.

  Hereinafter, the furniture fall prevention fixing structure (hereinafter referred to as “fixing structure”), the fall prevention fixing tool (hereinafter referred to as “fixing tool”), and the fall prevention fixing method (hereinafter referred to as “fixing method”) of the present invention will be described. Will be described with reference to FIG.

  FIG. 1 is a perspective view of a preferred embodiment of the fixture of the present invention. The fixture 1 of the present invention basically includes a back support portion 2 that supports the back surface of furniture, a wall surface fixing portion 4 for fixing the fixture 1 to a wall surface, and any one of a top surface, a side surface, and a bottom surface of the furniture. The example of FIG. 1 is the form which provided the upper surface support part 3 which supports the upper surface of furniture as this auxiliary support part.

  Usually, since furniture arranges the back side along a wall surface, the wall surface fixing | fixed part 4 and the back surface support part 2 become a continuous flat plate shape. Moreover, the back support part 2 and the auxiliary support part are formed in a direction in which the support surfaces of the furniture are orthogonal to each other.

  Further, in the fixing device 1 of the present invention, the method of fixing the wall surface fixing portion 4 to the wall surface is not particularly limited, but it is preferably fixed by screws or nails. In the example of FIG. A long hole 5 is provided in the wall surface fixing portion 4. Here, if only screws or nails are passed, it is sufficient to provide a circular hole that matches the size of the screws or nails, but the interior of the wall of a normal house is spaced at a predetermined interval in the vertical direction. A plurality of horizontal rails and reinforcing members are arranged, and the configuration is standardized. Therefore, in order to fasten the screws and nails to the crosspieces and the reinforcing material, it is necessary to be able to freely select the positions of the screws and nails in the wall surface fixing portion 4. As shown in FIG. 1, if a plurality of long holes 5 that are long in the vertical direction are provided in the vertical direction, a screw or a nail can be fastened to a cross rail or a reinforcing material through any of the long holes 5.

  FIG. 2 schematically shows another form of the fixture 1 of the present invention. (A)-(e) is a form which has the side surface support part 7 as an auxiliary | assistant support part, (f) is a form which has the upper surface support part 3 as an auxiliary | assistant support part.

  In the present invention, the back support portion 2 and the auxiliary support portion may be formed separately and then integrated, but preferably, the back support portion 2 and the auxiliary support portion are perpendicular to each other in terms of strength. It is preferable to bend it into two. Therefore, although the fixture of the present invention is configured using a resin plate or a metal plate, it is preferably formed by bending the metal plate at a predetermined position. As the material for the metal plate, stainless steel, aluminum, iron or the like is preferably used.

  (A) of FIG. 2 is an example in which the end portion of the side surface support portion 7 is attached later to the boundary portion between the flat plate-like back surface support portion 2 and the wall surface fixing portion 4 that are continuous in the horizontal direction, and (b) ) To (e) are examples in which a part of the flat plate member is bent at a right angle to form the side surface support portion 7. Moreover, (f) is an example in which the upper surface support portion 3 is attached later to the boundary portion between the flat plate-like rear surface support portion 2 and the wall surface fixing portion 4 which are continuous in the vertical direction. As an example in which the bottom surface support portion is provided as the auxiliary support portion, the fixture 1 of FIG. 1 may be used in the reverse direction in the vertical direction.

  2, (a) to (d) are forms in which the wall surface fixing part 4 is arranged on the side of the side surface of the furniture, and (e) and (f) are arranged on the upper surface of the furniture in the wall surface fixing part 4. It is a form. Therefore, (a) to (d) are used when there is a sufficient space on the side of the furniture at least when arranging the furniture. Further, (e) and (f) are respectively used when a sufficient space exists on the upper surface of the furniture when the furniture is arranged.

  FIG. 3 shows a state in which the furniture 30 is fixed to the wall surface using the fixture 1 of FIG. Moreover, FIG. 4 shows the state which fixed the furniture 30 to the indoor wall surface using the fixture [FIG.2 (d)] which has the side surface support part 7 as an auxiliary | assistant support part. In the figure, reference numeral 34 denotes an interior material, in which a cross rail 33 is arranged at a predetermined interval. As shown in FIGS. 3 and 4, in the present invention, the back support part 2 and the auxiliary support parts 3 and 7 of the fixture 1 are attached to the furniture 30 via the viscoelastic member 32, and the wall surface fixing part 4 is a long hole. 5 is fixed to the wall surface with screws or nails 31. The screw or nail 31 is fixed to the cross rail 33 with the interior material 34 interposed therebetween.

  As the viscoelastic member 32 used in the present invention, for example, a product marketed under the name of an earthquake-resistant gel mat is used, which is placed under furniture, a television, etc., to reduce the shaking of the furniture or the television in the event of an earthquake. Can do. When the fixture 1 is attached to the furniture 30 using such a viscoelastic member 32, the support surface of the fixture 1 and the furniture 30 adhere well due to the adhesive force of the viscoelastic member 32, and even when the fixture 1 is removed. The trace is not left on the furniture 30. Further, when an earthquake occurs, the viscoelastic member 32 is deformed to absorb the vibration energy of the furniture, so that the furniture 30 can be prevented from shaking, and the furniture 30 can be prevented from falling.

  Here, as shown in FIGS. 3 and 4, since the viscoelastic member 32 has a thin mat shape, the vibration direction of the vibration energy absorbed by the viscoelastic member 32 is the support of the furniture of the fixture 1. The direction parallel to the surface (the direction parallel to the surface of the furniture). Therefore, the width direction of furniture 30 (horizontal direction parallel to the wall and the back) is the X direction, the depth direction of furniture 30 (horizontal direction parallel to the side surface) is the Y direction, and the height direction of furniture 30 (vertical direction) is the Z direction. Direction, the back support 2 absorbs vibrations in the X and Z directions, the top support 3 and bottom support (not shown) absorb X and Y directions, and the side support 7 absorbs vibrations in the Y and Z directions. Can be relaxed. Since the fixture 1 of the present invention includes the back surface support portion 2 and either the top surface support portion 3 or the side surface support portion 7 or the bottom surface support portion (not shown), any vibration in the X, Y, and Z directions. Can also be absorbed and relaxed.

  In addition, the area and shape of each support part 2, 3, 7, the area and shape of the viscoelastic member 32, the attachment position and the number of fixtures are appropriately selected depending on the weight and shape of the furniture 30, the size of each surface, etc. Therefore, the present invention is not particularly limited. In appearance, since it looks bad if the viscoelastic member 32 protrudes outside the support portions 2, 3, and 7, it is desirable that the viscoelastic member 32 fit within the support portions 2, 3, and 7. Moreover, since it is unpreferable on an external appearance if the upper surface support part 3 and the side surface support part 7 are too large, it is preferable to make it as small as possible or to attach in the position which is not conspicuous as much as possible.

  As a fixing method using the fixing tool 1 of the present invention, first, the fixing tool 1 is selected according to the arrangement position of the furniture 30 on the wall surface and attached to a predetermined position of the furniture 30 via the viscoelastic member 32. At this time, in order to securely attach the fixture 1 to the furniture 30, it is preferable to leave it for a predetermined time with a predetermined load. As such a load, the furniture 30 itself may be used. Specifically, the furniture 30 is tilted so that one of the support portions 2, 3, 7 to be fixed is under the furniture 30, and an appropriate weight is applied to the other. It can be placed for several hours to several days.

Furthermore, when the fixture 1 of the present invention includes the upper surface support portion 3 as shown in FIG. 1, a distance Z ₃ from the upper surface support portion 3 to the uppermost portion of the long hole 5 provided in the wall surface fixing portion 4 is set to a predetermined value. By setting the length, vibration in the Y direction can be suppressed by the elastic action of the wall surface fixing portion 4 and the back surface support portion 2 of the fixture 1. The distance Z ₃ is preferably about 10 to 40 cm.

  Moreover, in this invention, when the back surface support part 2 and the auxiliary support parts 3 and 7 are formed by bending a flat plate member, it is preferable to provide a rib in order to reinforce the bent part. The rib is formed in a straight line extending in a direction perpendicular to the bent portion. The example of FIG. 1 is an example in which the rib 6 a is provided on the upper surface support portion 3, and the rib 6 a is formed in a direction orthogonal to the bent portion 8 that connects the upper surface support portion 3 and the back surface support portion 2. .

  Further, the rib 6 a is formed so as to protrude toward the support surface side of the furniture 30. FIG. 5 is a schematic cross-sectional view of a portion where the fixture 1 of FIG. 1 is attached to the furniture 30. As shown in FIG. 5, the rib 6 a is formed so as to protrude toward the support surface side of the furniture 30. When the vibration in the X direction occurs, the rib 6a protruding toward the viscoelastic member 32 acts to suppress the deformation of the viscoelastic member 32 in the X direction due to the vibration, and as a result, the vibration of the furniture 30 is further suppressed. be able to.

  That is, the rib 6 a has two functions of reinforcing the bent portion 8 and suppressing vibration of the furniture 30.

  In the example of FIG. 1, the rib 6 a is formed only on the upper surface support portion 3, but a similar rib can be provided on another support portion. FIG. 6A is an example provided also on the back support 2, and FIG. 6B is an example provided on the side support 7 and the back support 2. Such ribs 6a to 6c can be formed by using a metal plate as a material of the fixture 1, bending the metal plate to form each support portion, and then hitting a predetermined position. The ribs 6a and 6b in FIG. 6A both reinforce the bent portion 8 and suppress vibration in the X direction. Further, the ribs 6a and 6b in FIG. 6B reinforce the bent portion 9 and simultaneously suppress the vibration in the Z direction.

  The vibration energy absorption action of the rib 6a extending in the direction orthogonal to the bent portion 8 is the direction orthogonal to the rib 6a, that is, the direction parallel to the bent portion 8. Therefore, it is also a preferable form to provide a linear rib parallel to the bent portion 8 for the purpose of absorbing vibration energy in a direction orthogonal to the bent portion 8. FIG. 7A is an example in which ribs 10a and 10b according to the upper surface support portion 3 and the back surface support portion 2 are provided, and FIG. 7B is a rib 10c according to the side surface support portion 7 and the back surface support portion 2, respectively. 10b. As shown in FIG. 7, by providing the bi-directional ribs, the bi-directional vibration suppression effect by each support portion can be better obtained.

  The fixture 1 without the rib 6a having the shape shown in FIG. 1 was manufactured, and the actual furniture was fixed to the wall surface, and the vibration test was performed to measure the tolerable seismic intensity. The outer dimensions of the furniture were 93 cm wide, 30 cm deep, 177.5 cm high, and weights were distributed inside so that the weight would be 750 kg as a whole. The floor on which the furniture is installed is flooring, and the wall surface is a normal cloth.

In addition, the dimensions of the fixture 1 are X ₁ = 132 mm, X ₂ = 100 mm, X ₃ = 82 mm, Y ₁ = 100 mm, Z ₁ = 1000 mm, Z ₂ = 70 mm, Z ₃ = 270 mm, Z ₄ = in FIG. 50 mm. The width of the long holes 5 was 4.5 mm, and eight holes were provided at intervals of 30 mm in the vertical direction. The fixtures 1 were attached to both ends of the upper surface of the furniture in the horizontal direction with a seismic mat having approximately the same area as the support portion, and fixed to the wall with two screws. The viscoelastic member is usually crimped to the entire surface of the support part. However, especially when the back support part has a convex part such as a crosspiece on the furniture, the viscoelastic member is attached.

  When the shaking table was vibrated in the above state, the furniture did not fall even at a seismic intensity of 6.3 (maximum acceleration: 1128 gal), and returned to its original state after the vibration stopped. Therefore, according to this invention, it turned out that it can endure a vibration with a seismic intensity of about 6.3.

  The present invention is applied to prevent the fall of indoor furniture when a disaster such as an earthquake occurs.
