Description

  [Technical Field] The present invention relates to an aseismatic fixture that improves the earthquake resistance of a fixture.

  Various earthquake-resistant fixtures have been developed in order to prevent the fall and movement of fixtures due to earthquakes such as equipment installed in factories and parts storage shelves of warehouses. When a leg for height adjustment is attached to the fixture, the leg is individually fixed to ensure earthquake resistance (see, for example, Patent Document 1). In addition, in order to secure the fixture as a whole, prepare a plate-like member larger than the flat surface of the fixture that increases the coefficient of friction with the floor, and secure the legs for adjusting the height of the fixture to obtain earthquake resistance. (See, for example, Patent Document 2).

  However, the conventional fixing device for height adjustment described in Patent Document 1 is complicated in structure, takes time for installation, and tends to be expensive. Moreover, the plate-shaped earthquake-resistant fixture described in Patent Document 2 needs to be prepared before installing the fixture, and can not be used as a earthquake-proof measure for the fixture already installed.

  Since many of the fixtures required to have earthquake resistance do not have legs for adjusting the height, it was desirable to fix the fixtures using the side of the fixture. Therefore, an object of the present invention is to provide a seismic fixture that can be easily installed to suppress the movement of a fixture that does not have a height adjustment leg during an earthquake to increase seismic resistance.

  The anti-seismic fixing device of the present invention is a anti-seismic fixing device which is placed between a wall surface of a fixture and a fixed surface of a floor or wall of a building on which the fixture is installed to enhance the shock resistance of the fixture, the fixed surface A fixed surface attached portion attached to the housing and an appliance attached portion attached to the fixture are connected by a joint, and an angle between the fixed surface attached portion and the appliance attached portion at the joint is variable. Ru.

  Since there is a joint between the fixture attachment portion attached to the fixture and the fixed surface attachment portion attached to a fixed surface such as a floor or a wall, the degree of freedom of the angle between the fixture and the fixed surface is increased.

  In the earthquake-proof fixture of the present invention, the hole of the extension of the extension bolt connected to the fixed surface attachment at the joint and the hole provided at the fixture attachment are coaxially connected.

  Since the hole in the extension of the extension bolt connected to the fixed surface attachment and the hole provided in the fixture attachment are coaxially connected, the degree of freedom of the angle between the fixed surface attachment and the fixture attachment increases. .

  The earthquake resistant fixture of the present invention is a plate-like member in which the fixture attachment portion has a plurality of holes for connecting to the fixture.

  Since the fixture attachment portion has a plurality of holes for connecting to the fixture, the choice of the holes used flexibly in accordance with the location of the fixture holes is made easy to install the fixture.

  In the earthquake-proof fixture of the present invention, the plurality of holes of the plate-like member include holes of different sizes.

  Since the plurality of holes of the plate-like member include holes of different sizes, tap screws and the like can be coped with in addition to ordinary bolts.

  According to the present invention, since the fixtures and the floor surface are connected with a high degree of freedom, movement and falling of the fixtures installed on the floor surface can be easily suppressed during an earthquake.

BRIEF DESCRIPTION OF THE DRAWINGS (A) Front view which shows the Example of this invention, (B) It is a side view. It is explanatory drawing of the example of application to furniture.

  Hereinafter, embodiments of the present invention will be described based on the drawings. The earthquake-proof fixture of this embodiment shown in FIG. 1 is a earthquake-proof fixture which is placed between a fixed surface of a floor or wall of a building where the fixture is installed to enhance the earthquake resistance of the fixture. This earthquake-proof fixture comprises a fixed surface attachment portion 40 attached to a fixed surface such as a floor or a wall of a building, and a fixture attachment portion 9 attached to a wall surface of the fixture. The fixed surface attachment portion 40 includes the fixed surface adhesive plate 1 having the adhesive layer 2 and the fixed surface nut 3 with which the extension bolt 5 is screwed. The fixture attachment portion 9 is a plate-like member having a plurality of holes 10 and 11 of different sizes.

  The joint portion 41 is configured by combining the extension portion 6 of the extension bolt 5 and the lower end of the fixture attachment portion 9 freely connected to the fixture.

  The extension bolt has an extension on the head adapted to the required purpose. The extension bolt used this time is described using FIG. 1 (B). The extension bolt 5 is fusion-bonded to the head of the bolt at a position shifted so that one side of an extension 6 having a hole for inserting the coaxial bolt in the head is at the axial center of the bolt. At the connection part, the hole in the plate-like member of the attachment part of the fixture and the hole provided at the head of the extension are made coaxial and the coaxial bolt 7 is passed to freely take the angle between the attachment part of the fixed surface and the attachment part. be able to. By tightening the coaxial bolt 7 with the coaxial nut 8, the angle between the fixed surface attachment portion 40 and the fixture attachment portion 9 can be fixed.

  The installation procedure of the fastener of the present invention will be described below. (1) Temporarily fix the installation position of fixture and fixing surface and fix each nut temporarily. (2) Clean the surface used for bonding the fixture and the fixed surface with alcohol. (3) Remove the protective paper of the adhesive layer and apply the primer uniformly. (4) Bond the fixed surface attachment part. (5) Apply pressure so as to conform to the surface to which the adhesive layer is adhered. (6) When the predetermined position is determined, tighten each bolt of the fixture with a prescribed torque.

  FIG. 2 shows the case where the fixing device of the present invention is applied to an article shelf which is one of fixtures. Even for heavy fixtures, the fixture of the present invention has an overturning resistance and a transfer resistance of 300 Kg when the adhesive layer 3 with a diameter of 10 cmcm is used, so that the shock resistance of the fixture can be effectively improved.
