A second end member fixed to the other end of the cylindrical member and in contact with the floor surface is overlapped in the height direction of the cylindrical member at a predetermined pitch, thereby being embedded in the thick part of the cylindrical member. and a ring.
本発明は筺体を設置すべき床面から支持するよう該筺体
の底部に係止される台足に関する。The present invention relates to a pedestal that is secured to the bottom of a casing so as to support the casing from the floor on which the casing is installed.
電子機器を収納する筺体は、通常、第４図の筺体の設置
説明図に示すように形成されている。第４図の（ａ）は
側面図、（ｈ）は底部の平面図である。A casing that houses an electronic device is usually formed as shown in the illustrative diagram of casing installation in FIG. 4. FIG. 4(a) is a side view, and FIG. 4(h) is a plan view of the bottom.
第４図の（ａ） （ｂ）に示すように、筺体１の底部２
のコーナ部には台足１１が設けられ、台足１１を設置す
べき床面７に配設し、筺体ｌを所定個所に設置すること
が行われる。As shown in FIGS. 4(a) and (b), the bottom 2 of the housing 1
A pedestal foot 11 is provided at a corner portion of the pedestal 11, and the pedestal foot 11 is placed on the floor surface 7 where it is to be installed, and the casing 1 is installed at a predetermined location.
最近、このような台足１１の配設に際しては、地震によ
る耐震対策が施され、地震の発生による筺体ｌに対する
影響が極力なくすようにすることが行われている。Recently, when arranging such a pedestal 11, earthquake-resistant measures have been taken to minimize the effects of an earthquake on the casing l.
したがって、台足１１には、免震対策が備えられるよう
に形成され、台足１１を床面７に配設することで免震効
果が得られるように形成されることが望まねている。Therefore, it is desired that the pedestal 11 be formed so as to be provided with a seismic isolation measure, and that the pedestal 11 be formed so as to provide a seismic isolation effect by disposing it on the floor surface 7.
従来は第３図の従来の説明図に示すように構成されてい
た。第３図の（ａ）は側面図、 （ｂｌ） （ｂ２）は
台足の要部側面図である。Conventionally, the configuration was as shown in the conventional explanatory diagram of FIG. FIG. 3(a) is a side view, and FIG. 3(b2) is a side view of the main part of the pedestal.
第３図の（ａ）に示すように、台足１１のネジ部１１＾

り成る厚みＴのシー目２を介して台足１１のフランジ部
１１Ｂが床面７に当接され、台足１１によって筺体ｌの
支持が行われていた。As shown in FIG. 3(a), the threaded portion 11^ of the pedestal 11
The flange portion 11B of the base foot 11 is brought into contact with the floor surface 7 through the seam 2 of thickness T made of an elastic material, and the base foot 11 is attached to the bottom portion 2 of the housing l. was supported.
そこで、床面７に（ｂｌ）に示すように、矢印への地震
波が生じた場合は、シー目２が点線で示すように変形し
、この変形量Ｈによってフランジ部ｌＩＢが移動され、
地震波が筺体ｌに伝達されることを防ぎ、免震効果を得
ることが行われていた。Therefore, when a seismic wave is generated in the direction of the arrow on the floor surface 7 as shown in (bl), the seam 2 is deformed as shown by the dotted line, and the flange portion IIB is moved by the amount of deformation H.
This was done to prevent seismic waves from being transmitted to the housing 1 and to obtain a seismic isolation effect.
この場合、大きな地震波に対しても免震効果が得られる
ようにするためには（ｂ２）に示すように、シート１２
の厚みをＴＩのように大きくすることで、変形量をＭｌ
のように大きくし、フランジ部１１Ｂの移動を増加させ
ることが考えられる。In this case, in order to obtain a seismic isolation effect even against large seismic waves, the sheet 12 should be
By increasing the thickness of TI, the amount of deformation becomes Ml
It is conceivable to increase the movement of the flange portion 11B by increasing the size as shown in FIG.
このようなシート１２を介在させることで台足１１を床
面７に配設させる構成では、シー目２の厚みをＴＩのよ
うに太きすることで、フランジ部１１Ｂの揺動振幅を大
きくすることによって大きな地震波に対しても免震効果
が得られるようにする必要がある。In a configuration in which the base foot 11 is disposed on the floor surface 7 by interposing such a sheet 12, the thickness of the seam 2 is increased as in TI to increase the swing amplitude of the flange portion 11B. By doing so, it is necessary to obtain a seismic isolation effect even against large seismic waves.
しかし、シート１２の厚みをＴ１のように太きすると第
３図の（ｂ２）の鎖線で示すように、筺体ｌの重量によ
ってシート１２が太鼓形になり、実際には大きな変形量
が得られなくなる。However, if the thickness of the sheet 12 is increased to T1, the sheet 12 becomes drum-shaped due to the weight of the casing l, as shown by the chain line in (b2) of FIG. 3, and a large amount of deformation is actually obtained. It disappears.
したがって、シート１２の厚みをＴＩを大きくすること
は限界があり、大きな地震波に対する免震効果を得るこ
とは困難となる問題を有していた。Therefore, there is a limit to increasing the thickness of the sheet 12 to increase the TI, and there is a problem in that it is difficult to obtain a seismic isolation effect against large seismic waves.
そこで、本発明では、大きな地震波が発生しても免震効
果を得られるように形成することを目的とする。Therefore, an object of the present invention is to form a structure so that a seismic isolation effect can be obtained even if a large seismic wave occurs.
第１図は本発明の原理説明図である。 FIG. 1 is a diagram explaining the principle of the present invention.

A first end member 4 is fixed to one end of the cylindrical member 3 and locked to the bottom 2 via a connector 9, and a first end member 4 is fixed to the other end of the cylindrical member 3 and abuts against the floor 7. It is made up of a second end I material 5 and a ring 6 which is buried in the thick portion 3A of the cylindrical member 3 by being overlapped in the height direction of the cylindrical member 3 at a predetermined pitch P.
このように構成することによって戦術の課題は解決され
る。This configuration solves the tactical problem.
即ち、所定ピッチＰでリング６が埋設された弾性材より
成る筒部材３の一端に固着された第１の端部材４を筺体
１の底部２に連結具９を介して係止し、筒部材３の他端

得られるようにすることができる。Therefore, since the ring 6 is embedded in the cylindrical member 3, even if the height of the cylindrical member 3 is increased, the height of the cylindrical member 3 does not become drum-shaped due to the weight of the casing l as in the conventional case. By increasing the height, it is possible to increase the amount of deformation of the cylindrical member 3, and it is possible to obtain a seismic isolation effect even against large seismic waves.
（実施例） 以下本発明を第２図を参考に詳細に説明する。(Example) The present invention will be explained in detail below with reference to FIG.

相５が床面７に当接されるように構成したものである。As shown in FIG. 2(a), the thick part 3A of the cylindrical member 3, which is made of an elastic material such as rubber and has a hollow part 3B, has a plurality of holes arranged at a predetermined pitch P. A ring 6 is buried therein, a first mating ring 4 made of a metal material is fixed to one end of the cylindrical member 3, and the ring 6 is connected to the bottom part 2 of the casing l via a connector 9 provided on the first mating part 4. On the other hand, a second mat 4 made of a metal material is fixed to the other end of the cylindrical member 3, so that a second mat 5 comes into contact with the floor 7.

A groove 5A is provided in the first step 5, and the second step 5 is connected to the floor surface 7.
It is formed to be in close contact with the

止された第１の瑞相４との間にＭ２に示す変形量が筒部
材３に生じ、筺体１に対する免震効果が得られるように
したものである。Therefore, as shown in (b), when a horizontal force in the direction of the arrow due to seismic waves is applied to the floor surface 7, the cylindrical member 3 deforms,
A deformation amount indicated by M2 is generated in the cylindrical member 3 between the first abutment 5 in contact with the floor surface 7 and the first abutment 4 locked on the flange portion 9^, and the isolation for the housing 1 is This is to create a seismic effect.
この場合、筒部材３に中空部３Ｂを形成することで筒部

なった振動に対しての最適なバネ定数の設定が行え、種
々の振動に対する幅の広い選択が行えることになる。In this case, by forming the hollow part 3B in the cylindrical member 3, the deformation of the cylindrical member 3 becomes easier, and, for example, it is more susceptible to vibrations with different frequencies compared to a cylindrical member in which the hollow part 3B is not formed. The optimum spring constant can be set for various vibrations, and a wide range of selections can be made for various vibrations.
また、このような構成では、筒部材３の高さＨを高くし

於ける変形量Ｍ２は、筒部材３の半径Ｐよりも、小さく
なるように筒部材３のサイズを配慮する必要がある。In addition, in such a configuration, even if the height H of the cylindrical member 3 is increased, it will not become drum-shaped as in the conventional case, so the height 1
1 can be freely set, and the amount of deformation can be increased (by doing so, it is possible to obtain a seismic isolation effect against large seismic waves. To avoid this, it is necessary to consider the size of the cylindrical member 3 so that the amount of deformation M2 in the cylindrical member 3 is smaller than the radius P of the cylindrical member 3.
以上説明したように、本発明によれば、リングが埋設さ
れた筒部材を設けることで、筒部材の高さを高くし、適
切なバネ定数の設定により、大きな変形量が得られるよ
うにしたものである。As explained above, according to the present invention, by providing a cylindrical member in which a ring is embedded, the height of the cylindrical member is increased, and by setting an appropriate spring constant, a large amount of deformation can be obtained. It is something.
