Description

  The present invention relates to a seismic support device such as furniture.

  2. Description of the Related Art Conventionally, as an earthquake-resistant support device for furniture or the like, for example, there is one using a coil spring. This seismic support device is composed of a fixed piece, an L-shaped attachment piece, and a coil spring between the fixed piece and the attachment piece. The fixed piece is fixed to the wall, and the attachment piece is attached to the top plate of the furniture. .

  A dynamic load is applied to the mounting piece due to vibration acceleration input to the furniture during an earthquake, and this dynamic load is buffered by the coil spring.

  Therefore, when the fixed piece is fixed to the wall by a nail or the like, it is possible to restrict the dynamic load at the time of the earthquake from being directly input to the nail, to suppress the removal of the nail and to prevent the furniture from falling.

  However, in the structure as described above, since the coil spring is merely interposed between the fixed piece and the mounting piece, it is difficult to increase the support rigidity.

A resistor that encloses or applies a fluid viscous material such as grease having viscous resistance between the contact surfaces with the support member and generates viscous resistance by relative movement in the surface direction caused by the operation of the supported body. Since the surface is provided, it is possible to easily obtain a seismic support device capable of absorbing energy using a viscous resistance of a fluid viscous material such as grease on a supported material such as furniture.

  A resistance that generates at least one of frictional resistance or viscous resistance between the fixed member and the supporting member due to the relative movement between them, for the purpose of enabling energy absorption while improving the supporting rigidity of the supported object such as furniture Realized by providing a surface.

  The seismic support device E1 according to the first embodiment of the present invention includes a fixing member 10 attached to a fixing side H such as a wall surface and a supporting member 20 attached to a supported body K such as furniture, and one side 10a of the fixing member 10. An attachment portion 11 to a fixed side H such as a wall surface is formed on the other side, and a long hole 12 is provided on the other side 10b extending to the support member 20 side to allow relative movement between the two. 10 and the support member 20 are fastened by a fastener B such as a bolt 30 and a nut 31.

  More specifically, in this embodiment, the fixing member 10 is formed of an elastic-plastic resin, the one side 10a is bent in an L shape to form the attachment portion 11, and a gel-like adhesive sheet is formed on the outer surface thereof. 13 is mounted, and the long hole 12 that allows relative movement with the support member 20 is provided along the axis of the fixing member 10 at a position close to the other side 10b.

  In this embodiment, the support member 20 is also formed of an elastic-plastic resin in the same manner as the fixing member 10, and both ends in the longitudinal direction are bent to the supported body K side such as furniture to improve the strength of the support member 20. The gel-like pressure-sensitive adhesive sheet 21 is mounted between the bent portions 20a and 20b. The surface of the pressure-sensitive adhesive sheet 21 on the supported body K side is mounted so as to protrude from the end surfaces on the supported body K side of the bent portions 20a and 20b.

  As described above, the fixing member 10 and the support member 20 are fastened via the long hole 12 so that the friction resistance can be adjusted by the bolt 30 and the nut 31 constituting the fastener B. Accordingly, the support member 20 attached to the supported body K can move by the length L of the long hole 12 with respect to the fixing member 10 attached to the fixed side H such as the wall surface. A dynamic load such as an earthquake can be reliably mitigated by the fastening frictional resistance of the sliding surface P as the resistance surface formed between the support member 20 and the resistance surface.

  Note that the fastening of the fixing member 10 and the supporting member 20 is not possible to adjust the frictional resistance as described above, and the fastening may be performed by fixing the frictional resistance between them to a required value. In this embodiment, the bolt 30 and the nut 31 are used as the fastener B, but this may be fastened by a rivet or the like. The same applies to other embodiments described later.

  Further, in this embodiment, the gel-like pressure-sensitive adhesive sheets 13 and 21 are used as attachment means to the attachment portion, but this may be an adhesive tape, screwed, or a combination thereof.

Can do.

  Further, when the dynamic load increases and exceeds the set frictional force based on the fastening, the fixed member 10 and the support member 20 move relative to each other, and are moved by the frictional resistance between the sliding surfaces P as the resistance surfaces. Can absorb and relieve static load. The range of this movement is the range of the length L of the long hole 12 formed in the fixed member 10, and the dynamic load input by the fastening frictional resistance between the fixed member 10 and the support member 20 is ensured within this range. Can be relaxed.

  When the dynamic load further increases and exceeds the allowable range, and the deformation of the attachment portion 11 bent in the L shape exceeds the elastic limit, the attachment portion 11 is plastically deformed to absorb the dynamic load. To do. As a result, in addition to absorbing energy in the range of elastic deformation, energy can be absorbed even in plastic deformation, and the load in the separation direction acting on the fixing member 10 and the support member 20 can be reduced. The fixing member 10 and the support member 20 can be prevented from being detached from the attached portion such as a wall or furniture.

  In order to perform energy absorption by this plastic deformation, it is preferable to screw the fixing member 10 and the support member 20.

  In addition, the dynamic load in the input direction orthogonal to the mounting direction is also caused by the mutual rotation of the fixing member 10 and the support member 20 with the frictional resistance around the fastening portion S by the bolt 30 and the nut 31 described above. Can be relaxed.

  In addition, instead of the pressure-sensitive adhesive sheets 13 and 21, a foam material made of sponge may be integrally attached to the attachment portions of the fixing member 10 and the support member 20 to the wall or furniture. The thickness of these foam materials may be selected as necessary, and it is a matter of course that the surface has an adhesive function and a release sheet is attached. When the foam material is used in this way, the buffering effect can be further improved.
