Description

The present invention relates to a seismic fixture that enhances the seismic resistance of furniture.

Various seismic fixtures have been developed to prevent furniture such as furniture installed in factories and warehouse parts storage shelves from tipping over or moving during an earthquake. When the furniture is equipped with legs for height adjustment, the legs are individually fixed to ensure earthquake resistance (see, for example, Patent Document 1). In addition, in order to fix the furniture as a whole, it is possible to prepare a plate-shaped member larger than the flat surface of the furniture with a large coefficient of friction with the floor and fix the legs for adjusting the height of the furniture to obtain earthquake resistance. It has been done (see, for example, Patent Document 2).

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The seismic fixture of the present embodiment shown in FIG. 1 includes a fixing surface such as a floor surface or a wall surface of a building and two attachment portions to be attached to furniture. The fixed surface adhesive portion 40 at one end includes a fixed surface adhesive plate 1 having an adhesive layer 3 and a fixed surface nut 19 into which the fixed surface extension bolt 4 is screwed. Further, the furniture attachment portion 43 at the other end includes a fixture attachment plate 2 having an adhesive layer 3 and a fixture fixing portion nut 18 into which the fixture extension bolt 16 is screwed.

The first joint portion 41 is configured by combining the fixed surface extension bolt 4 and the first extension bolt 9. Further, the second joint portion 42 is configured by combining the furniture extension bolt 16 and the second extension bolt 13.

The extension bolt has an extension on the head of the bolt that is suitable for the intended purpose. The extension bolt used this time is shown in FIG. The extension bolt 30 is fused to the head of the bolt at a position where one side of the extension portion 31 having a hole 32 for inserting the bolt in the head is displaced so as to be the center of the bolt. By abutting the extension bolts 33 having different extension portions having the same structure and making the holes of the extension portions 31 and 34 coaxial and passing the coaxial bolt 35, the angle formed by the two extension bolts can be freely taken. By tightening the coaxial bolt 35 through the holes of the extension portions 31 and 34 with the coaxial nut 36, the angle formed by the two extension bolts 30 and 33 can be fixed.

By coaxially tightening the holes of the extension portions of the two extension bolts in this way, the angle formed by the two extension bolts at the joint portions 41 and 42 can be freely set.

The first extension bolt 9 constituting the first joint portion 41 and the second extension bolt 13 constituting the second joint portion are respectively screwed into the high nut 11. The connecting portion can be configured with various shapes and materials, and has a role of associating the fixed surface attachment portion 40 with the fixture attachment portion 43. The screwing length with the high nut 11 is determined by the distance between the first joint portion 41 and the second joint portion 42. The depth of screwing of the extension bolt into the high nut 11 can be changed to make the distance between the two joints 41 and 42 variable. After the screwing depth of the extension bolts 9 and 13 is determined, the fixing nuts 10 and 12 are tightened to fix the screwing length of each extension bolt.

Here, it is also possible to use a turnbuckle method by changing the screw engraved on one side to an inverted screw. The turnbuckle method makes it easy to change the distance between the two joints. If the middle part of the connecting part is made of an elastic body, the effect of softening the impact at the time of an earthquake can be expected. Further, by using a plurality of connecting portions and connecting the connecting portions with an extension member, the distance between the fixed surface attachment portion and the furniture attachment portion can be extended. Further, when the size of the adhesive layer 3 is 10 cmΦ as a standard, a fall resistance and a large amount of movement of 300 kg can be obtained, but when such a large resistance is not required, an adhesive layer such as 8 cmΦ can be used.
