Description

上下免震装置Vertical seismic isolation device
　本発明は、精密機器、電子機器、美術品等の免震対象物を地震等の外部振動、特に上下振動から保護する上下免震装置に関する。 The present invention relates to a vertical seismic isolation device that protects seismic isolation objects such as precision equipment, electronic equipment, and art objects from external vibrations such as earthquakes, particularly vertical vibrations.
　従来、精密機器、電子機器、美術品等の免震対象物の運搬時、あるいは建物内に設置した当該免震対象物に対する地震の作用時等、当該免震対象物の外部振動対策としては、これら免震対象物を床面の振動から断絶する目的で免震装置が用いられている。また、かかる免震装置としては、水平方向の振動を吸収する水平免震装置、上下方向の振動を吸収する上下免震装置、これら水平免震装置及び上下免震装置の機能を併せ持った三次元免震装置が公知である。 Conventionally, as a countermeasure for external vibration of the seismic isolation object, such as when carrying the seismic isolation object such as precision equipment, electronic equipment, art, etc., or when an earthquake acts on the seismic isolation object installed in the building, Seismic isolation devices are used to isolate these seismic isolation objects from floor vibrations. In addition, as such a seismic isolation device, a horizontal seismic isolation device that absorbs horizontal vibrations, a vertical seismic isolation device that absorbs vertical vibrations, and a three-dimensional function that combines the functions of these horizontal and vertical seismic isolation devices. Seismic isolation devices are known.
　このうち、上下免震装置の構造としては、特許文献１に開示されるように、可動フレームとしての建物基礎と固定フレームとしての基礎との間に所謂パンタグラフ機構と呼ばれる四節リンクからなる免震ユニットを配置したものが知られている。特許文献１の図１に示された前記免震ユニットは、四本のリンクをひし形に構成したものであり、一対のリンク支点部の間には引っ張りコイルバネが配置され、前記固定フレームに対して連結された固定端と前記可動フレームに対して連結された自由端との間には、これらが離反する方向の付勢力が作用している。これにより、前記可動フレームと前記固定フレームとの間に上下方向の振動が作用すると、前記固定端の対面にある前記自由端が平行移動して、前記可動フレームが前記固定フレームの振動から絶縁された状態で自由に上下動できるようになっている。 Among these, as disclosed in Patent Document 1, the vertical seismic isolation device has a seismic isolation consisting of a four-bar link called a pantograph mechanism between a building foundation as a movable frame and a foundation as a fixed frame. The one where the unit is arranged is known. The seismic isolation unit shown in FIG. 1 of Patent Document 1 has four links formed in a rhombus shape, and a tension coil spring is disposed between a pair of link fulcrum portions, with respect to the fixed frame. An urging force acting in a direction in which the fixed end and the free end connected to the movable frame are separated acts. As a result, when a vertical vibration is applied between the movable frame and the fixed frame, the free end facing the fixed end translates and the movable frame is insulated from the vibration of the fixed frame. It can be moved up and down freely in a standing state.
特開平１０－２１３１７７号公報JP-A-10-213177
　特許文献１の図１に示された免震ユニットは四節リンクであり、前記固定端を前記固定フレームに対して連結したのみでは自立することができない。従って、前記免震ユニットのみでは可動フレームの上下動を支えることはできず、当該可動フレームには水平方向への傾斜である所謂ロッキングが発生してしまう。 The seismic isolation unit shown in FIG. 1 of Patent Document 1 is a four-bar link, and cannot be self-supporting simply by connecting the fixed end to the fixed frame. Therefore, the seismic isolation unit alone cannot support the vertical movement of the movable frame, and so-called rocking that is inclined in the horizontal direction occurs in the movable frame.
　このため、特許文献１では前記可動フレームのロッキングを防止するために、前記固定フレームから側壁を立ち上げて、前記可動フレームが上下動する範囲を当該側壁で囲むと共に、当該側壁に設けた積層ゴムで前記可動フレームの水平方向の移動を規制している。 For this reason, in Patent Document 1, in order to prevent the movable frame from being locked, the side wall is raised from the fixed frame, and the range in which the movable frame moves up and down is surrounded by the side wall, and the laminated rubber provided on the side wall The movement of the movable frame in the horizontal direction is restricted.
　しかし、この構造では前記可動フレームの大きさに対して、前記固定フレームの大きさが大型化することになり、小型且つ軽量で取り扱いの容易な免震テーブルを実現することが難しいといった課題があった。また、前記可動フレームがロッキングを生じながら上下動する際には、前記側壁に設けた積層ゴムが前記可動フレームに当接していることになるので、前記積層ゴムが当該可動フレームの円滑な上下動を阻害し易いといった課題もあった。 However, this structure increases the size of the fixed frame relative to the size of the movable frame, and there is a problem that it is difficult to realize a seismic isolation table that is small, lightweight, and easy to handle. It was. Further, when the movable frame moves up and down while being locked, the laminated rubber provided on the side wall is in contact with the movable frame, so that the laminated rubber moves smoothly up and down of the movable frame. There was also a problem that it was easy to inhibit.
　本発明はこのような課題に鑑みなされたものであり、その目的とするところは、免震対象物を載せた可動フレームが円滑に上下動することが可能であると共に、小型且つ軽量で、取り扱いの容易な上下免震装置を提供することにある。 The present invention has been made in view of such problems, and the object of the present invention is that the movable frame on which the seismic isolation object is placed can move up and down smoothly, is small and lightweight, and is handled. It is to provide an easy vertical seismic isolation device.
　本発明の上下免震装置は、固定フレームと、免震対象機器が載置されると共に前記固定フレーム上に配置された可動フレームと、前記固定フレームに対する前記可動フレームの上下動のみを許容する支持案内機構と、前記可動フレームと固定フレームとの間隔を一定に保つべく当該可動フレームを付勢する復元部材とを備えている。前記支持案内機構は、前記固定フレーム上に敷設された軌道レールと、多数の転動体を介して前記軌道レールに組み付けられ、当該軌道レールの長手方向以外に作用する荷重を負荷する移動ブロックと、一端が前記移動ブロックに回転自在に連結されると共に他端が前記可動フレームに回転自在に連結され、前記可動フレームの上下動を前記移動ブロックの前記軌道レールに長手方向に沿った運動に変換する支持脚と、前記支持脚の半分の長さに設定され、一端が前記支持脚の長手方向の中間位置に回転自在に連結されると共に他端が前記固定フレームに回転自在に連結された補助脚とを備えている。 The vertical seismic isolation device of the present invention includes a fixed frame, a movable frame on which the seismic isolation target device is placed, and a support that allows only the vertical movement of the movable frame relative to the fixed frame. A guide mechanism and a restoring member that urges the movable frame to keep a constant distance between the movable frame and the fixed frame are provided. The support guide mechanism includes a track rail laid on the fixed frame, a moving block that is assembled to the track rail via a large number of rolling elements, and that applies a load acting in a direction other than the longitudinal direction of the track rail; One end is rotatably connected to the moving block and the other end is rotatably connected to the movable frame, and the vertical movement of the movable frame is converted into a movement along the longitudinal direction of the track rail of the moving block. A support leg, which is set to a half length of the support leg, and has one end rotatably connected to an intermediate position in the longitudinal direction of the support leg and the other end rotatably connected to the fixed frame And.
　前記支持案内機構の支持脚及び補助脚は所謂スコットラッセル機構を構成しており、前記固定フレームに対する前記可動フレームの運動方向を上下方向に制限している。従って、前記可動フレームはロッキングを生じることなく上下動を行う。 The support legs and auxiliary legs of the support guide mechanism constitute a so-called Scott Russell mechanism, and restrict the movement direction of the movable frame relative to the fixed frame in the vertical direction. Therefore, the movable frame moves up and down without causing locking.
　また、前記支持案内機構の支持脚の固定フレーム側の端部は前記移動ブロックに対して回転自在に連結されており、また、当該移動ブロックは前記固定フレームに敷設された前記軌道レールに対して多数の転動体を介して組み付けられており、当該軌道レールの長手方向以外に作用する荷重を負荷しながら当該軌道レールに沿って運動する。このため、前記可動フレームに対して大きな荷重が作用した場合でも、当該可動フレームの上下動を円滑に案内することができる。従って、本発明によれば、免震対象物を載せた可動フレームが円滑に上下動することが可能であると共に、小型且つ軽量で、取り扱いの容易な上下免震装置を提供することが可能となる。 The end of the support leg of the support guide mechanism on the fixed frame side is rotatably connected to the moving block, and the moving block is connected to the track rail laid on the fixed frame. It is assembled | attached via many rolling elements, and it moves along the said track rail, applying the load which acts other than the longitudinal direction of the said track rail. For this reason, even when a large load is applied to the movable frame, it is possible to smoothly guide the vertical movement of the movable frame. Therefore, according to the present invention, the movable frame carrying the seismic isolation object can smoothly move up and down, and it is possible to provide a vertical and vertical seismic isolation device that is small and lightweight and easy to handle.

　以下、添付図面を用いながら本発明の上下免震装置を詳細に説明する。 Hereinafter, the vertical seismic isolation device of the present invention will be described in detail with reference to the accompanying drawings.
　図１は本発明を適用した上下免震装置１の第一実施形態を示す正面図であり、本発明の上下免震装置の基本的な構成を示している。この上下免震装置１（以下、「免震装置」という）は、床面に載置される固定フレーム２と、精密機器、電子機器、美術品等の免震が必要とされる免震対象物を搭載する可動フレーム３と、前記固定フレーム２に対する前記可動フレーム３の上下方向（図１中の矢線Ｚ方向）への運動を案内する支持案内機構４と、前記可動フレーム３を前記固定フレーム２に対して弾性的に支承する復元部材５と、を備えている。 FIG. 1 is a front view showing a first embodiment of a vertical seismic isolation device 1 to which the present invention is applied, and shows a basic configuration of the vertical seismic isolation device of the present invention. This vertical seismic isolation device 1 (hereinafter referred to as “the seismic isolation device”) is a fixed frame 2 placed on the floor, and is subject to seismic isolation that requires seismic isolation such as precision equipment, electronic equipment, and art. A movable frame 3 for mounting an object, a support guide mechanism 4 for guiding the movement of the movable frame 3 in the vertical direction (the arrow Z direction in FIG. 1) relative to the fixed frame 2, and the movable frame 3 being fixed. And a restoring member 5 that elastically supports the frame 2.
　前記支持案内機構４は、前記固定フレーム２上に敷設された軌道レール４０と、この軌道レール４０に沿って自在に直線運動を行う移動ブロック４１と、前記可動フレーム３と前記移動ブロック４１とを連結する支持脚４２と、前記支持脚４２の長手方向の中間位置と前記固定フレーム２とを連結する補助脚４３とから構成されている。 The support guide mechanism 4 includes a track rail 40 laid on the fixed frame 2, a moving block 41 that freely moves linearly along the track rail 40, the movable frame 3, and the moving block 41. The support leg 42 to be connected and the auxiliary leg 43 to connect the intermediate position in the longitudinal direction of the support leg 42 and the fixed frame 2 are configured.
　図２は前記軌道レール４０及び前記移動ブロック４１の組み合わせの一例を示す斜視図であり、内部の構成が把握できるように一部を破断して描いてある。前記軌道レール４０には長手方向に沿ってボールやローラ等の転動体４４の転走面４５が形成される一方、前記移動ブロック４１には前記転動体４４の無限循環路が形成されており、かかる無限循環路内には多数の転動体４４が配列されている。前記移動ブロック４１は転動体４４を介して前記軌道レール４０に組み付けられており、前記転動体４４が前記軌道レール４０の転走面４５を転がることにより、当該移動ブロック４１は前記軌道レール４０に沿って自在に移動することが可能となっている。前記支持脚４２から前記移動ブロック４１に対して押圧力や引っ張り力が作用した場合であっても、前記移動ブロック４１が前記軌道レール４０から分離することなく当該軌道レール４０に沿って自在に移動することが可能となるよう、前記移動ブロック４１は軌道レール４０に組付けられた状態で、かかる軌道レール４０の長手方向と直交する面内に作用するあらゆる荷重を負荷できることが必要である。これら軌道レール４０及び移動ブロック４１の組み合わせとしては、市販の直線案内装置（例えば、ＬＭガイド／ＴＨＫ株式会社製）を利用することが可能である。また、前記軌道レール４０及び移動ブロック４１の耐荷重は、前記可動フレーム３上に設置する免震対象物の重量に応じて適宜選定することが可能である。 FIG. 2 is a perspective view showing an example of a combination of the track rail 40 and the moving block 41, which is partially broken so that the internal configuration can be grasped. The track rail 40 is formed with a rolling surface 45 of a rolling element 44 such as a ball or a roller along the longitudinal direction, while the moving block 41 is formed with an infinite circulation path of the rolling element 44, A large number of rolling elements 44 are arranged in the infinite circulation path. The moving block 41 is assembled to the track rail 40 via a rolling element 44, and the rolling block 44 rolls on the rolling surface 45 of the track rail 40, whereby the moving block 41 is attached to the track rail 40. It is possible to move freely along. Even when a pressing force or a pulling force is applied to the moving block 41 from the support leg 42, the moving block 41 moves freely along the track rail 40 without being separated from the track rail 40. In order to be able to do so, the moving block 41 needs to be able to load any load acting in a plane perpendicular to the longitudinal direction of the track rail 40 in a state where it is assembled to the track rail 40. As a combination of the track rail 40 and the moving block 41, a commercially available linear guide device (for example, manufactured by LM Guide / THK Co., Ltd.) can be used. Further, the load resistance of the track rail 40 and the moving block 41 can be appropriately selected according to the weight of the seismic isolation object installed on the movable frame 3.
　前記支持脚４２は前記可動フレーム３の上下動を前記移動ブロック４１に伝達するためのリンクであり、一端は前記可動フレーム３に、他端は前記移動ブロック４１に対して夫々回転自在に連結され、前記可動フレーム３と前記移動ブロック４１の間に傾斜して配置されている。前記支持脚４２は前記可動フレーム３及び前記移動ブロック４１の夫々に対して回転自在に連結することにより、前記軌道レール４０に沿った前記移動ブロック４１の運動を許容している。また、前記補助脚４３は前記支持脚４２の運動を制限するためのリンクであり、一端は前記支持脚４２に、他端は前記固定フレーム２に対して回転自在に連結されている。 The support leg 42 is a link for transmitting the vertical movement of the movable frame 3 to the moving block 41, and one end is connected to the movable frame 3 and the other end is rotatably connected to the moving block 41. The movable frame 3 and the moving block 41 are inclined. The support leg 42 is rotatably connected to the movable frame 3 and the moving block 41 to allow the moving block 41 to move along the track rail 40. The auxiliary leg 43 is a link for restricting the movement of the support leg 42, and one end is connected to the support leg 42 and the other end is rotatably connected to the fixed frame 2.
　前記補助脚４３の長さは前記支持脚４２の長さの半分であり、前記補助脚４３と前記支持脚４２との連結点は当該支持脚４２の長手方向の中間位置である。すなわち、前記支持脚４２と可動フレーム３の連結点をＡ、前記支持脚４２と移動ブロック４１の連結点をＢ、前記補助脚４３と前記固定フレーム２の連結点をＣ、前記支持脚４２と前記補助脚４３との連結点をＤとした場合に、ＡＤ＝ＢＤ＝ＣＤとなるように設定されている。すなわち、前記支持案内機構４は所謂スコットラッセル機構を構成している。 The length of the auxiliary leg 43 is half of the length of the support leg 42, and the connecting point between the auxiliary leg 43 and the support leg 42 is an intermediate position in the longitudinal direction of the support leg 42. That is, the connection point between the support leg 42 and the movable frame 3 is A, the connection point between the support leg 42 and the moving block 41 is B, the connection point between the auxiliary leg 43 and the fixed frame 2 is C, and the support leg 42 is When the connection point with the auxiliary leg 43 is D, AD = BD = CD is set. That is, the support guide mechanism 4 constitutes a so-called Scott Russell mechanism.
　このような支持案内機構４では、前記可動フレーム３と前記支持脚４２との連結点Ａが上下動すると、前記移動ブロック４１と前記支持脚４２との連結点Ｂが前記軌道レール４０に沿って前記固定フレーム２上を移動することになる。この際、前述の如くＡＤ＝ＢＤ＝ＣＤなので、前記補助脚４３と前記固定フレーム２との連結点Ｃは連結点Ａと連結点Ｂを結ぶ線分を直径とした仮想円上に位置していることになり、∠ＡＣＢは常に直角となる。これにより、連結点Ａは図１の紙面左右方向には移動することなく、連結点Ｃの直上を真っ直ぐに上下動することになる。従って、前述の連結点Ａのロッキングを防止しながら、前記可動フレーム３を自由に上下動させることが可能となっている。 In such a support guide mechanism 4, when the connection point A between the movable frame 3 and the support leg 42 moves up and down, the connection point B between the moving block 41 and the support leg 42 moves along the track rail 40. It moves on the fixed frame 2. At this time, since AD = BD = CD as described above, the connection point C between the auxiliary leg 43 and the fixed frame 2 is located on a virtual circle whose diameter is a line segment connecting the connection point A and the connection point B. ∠ACB is always at a right angle. Thus, the connecting point A moves up and down straight above the connecting point C without moving in the left-right direction in FIG. Accordingly, it is possible to freely move the movable frame 3 up and down while preventing the locking of the connecting point A described above.
　一方、前記復元部材５は所謂ねじりばねから構成されており、一方の腕部５０は前記可動フレーム３に、他方の腕部５１は前記固定フレーム２に対して夫々回転自在に連結されている。このため、前記可動フレーム３が静止していた定常位置から下降又は上昇のいずれが生じても、前記復元部材５は当該可動フレーム３に対して付勢力を及ぼし、当該可動フレーム３を定常位置へ引き戻すことになる。 On the other hand, the restoring member 5 is formed of a so-called torsion spring, and one arm portion 50 is rotatably connected to the movable frame 3 and the other arm portion 51 is rotatably connected to the fixed frame 2. Therefore, regardless of whether the movable frame 3 is lowered or raised from the stationary position where the movable frame 3 is stationary, the restoring member 5 exerts an urging force on the movable frame 3 to bring the movable frame 3 to the stationary position. Will pull back.
　前記復元部材５はねじりばねに限定されるものではなく、コイルばねや板ばね等の各種弾性部材を使用することが可能である。また、前記復元部材５の取付け位置は図示の位置に限定されるものではなく、前記可動フレーム３と固定フレーム２との間隔を一定に保つべく当該可動フレーム３を付勢することができる位置であれば、図示の位置以外であっても差し支えない。 The restoring member 5 is not limited to a torsion spring, and various elastic members such as a coil spring and a leaf spring can be used. Further, the mounting position of the restoring member 5 is not limited to the illustrated position, and the movable frame 3 can be urged so as to keep the distance between the movable frame 3 and the fixed frame 2 constant. If it exists, it may be other than the illustrated position.
　例えば、図３に示すように、前記移動ブロック４１と固定フレーム２との間に復元部材５としてのコイルばねを設け、前記軌道レール４０上における前記移動ブロック４１の移動に対して復元部材５の付勢力を及ぼすようにしてもよい。また、図４に示すように、前記補助脚４３に延長部４３ａを設けて当該補助脚４３を前記支持脚４２とＸ字状に交差させ、前記延長部４３aの先端とその直下に位置する前記移動ブロック４１との間に復元部材５としてのコイルばねを設けてもよい。 For example, as shown in FIG. 3, a coil spring as a restoring member 5 is provided between the moving block 41 and the fixed frame 2, and the restoring member 5 is moved against the movement of the moving block 41 on the track rail 40. An urging force may be exerted. Further, as shown in FIG. 4, the extension leg 43a is provided on the auxiliary leg 43 so that the auxiliary leg 43 intersects the support leg 42 in an X shape, and the tip of the extension part 43a is located immediately below the tip. A coil spring as the restoring member 5 may be provided between the moving block 41 and the moving block 41.
　そして、以上のように構成された第一実施形態の免震装置１は、前記固定フレーム２を建物や運搬車輛の床面に設置する一方、前記可動フレーム３上には精密機器、美術品等の免震対象物を載置して使用される。 And the seismic isolation apparatus 1 of 1st embodiment comprised as mentioned above installs the said fixed frame 2 on the floor surface of a building or a transport vehicle, On the said movable frame 3, a precision instrument, a work of art, etc. Used for mounting seismic isolation objects.
　例えば運搬や地震等に起因して前記床面に対して振動が作用すると、かかる床面の振動が固定フレーム２及び可動フレーム３を介して免震対象物に伝播し、免震対象物も振動することになる。しかし、前述の如く、前記可動フレーム３は前記固定フレーム２に対して自由に上下動することが可能であり、当該可動フレーム３は固定フレーム２の上下動の振幅及び周期とは無関係に振動することが可能である。このため、免震対象物を搭載した可動フレーム３は固定フレーム２の上下動からは絶縁された状態にあり、床面の上下動に拘束されることなく、当該上下動に比べて長周期の振動で上下に揺れることが可能となっている。これにより、床面の振動による前記免震対象物の損傷を効果的に防止することが可能となる。 For example, when vibration acts on the floor surface due to transportation or an earthquake, the vibration of the floor surface propagates to the seismic isolation object via the fixed frame 2 and the movable frame 3, and the seismic isolation object also vibrates. Will do. However, as described above, the movable frame 3 can freely move up and down with respect to the fixed frame 2, and the movable frame 3 vibrates regardless of the amplitude and period of the vertical movement of the fixed frame 2. It is possible. For this reason, the movable frame 3 on which the seismic isolation object is mounted is insulated from the vertical movement of the fixed frame 2 and is not restricted by the vertical movement of the floor surface. It can swing up and down by vibration. This makes it possible to effectively prevent damage to the seismic isolation object due to floor vibration.
　この際、本発明の免震装置では、前記固定フレーム２に対する前記可動フレーム３の上下動を支える支持案内機構４は所謂スコットラッセル機構を構成しており、前記可動フレーム３は前記支持案内機構４の働きによってロッキングを生じることなく上下動することが可能である。また、前記支持案内機構４の支持脚４２の固定フレーム２側の端部は、軌道レール４０に組み付けられた移動ブロック４１に連結されており、当該支持脚４２に対して大きな押圧力又は引っ張り力が作用した際でも固定フレーム２上を円滑に移動することが可能である。 At this time, in the seismic isolation device of the present invention, the support guide mechanism 4 that supports the vertical movement of the movable frame 3 with respect to the fixed frame 2 constitutes a so-called Scott Russell mechanism, and the movable frame 3 is the support guide mechanism 4. It is possible to move up and down without causing locking by the action of. The end of the support leg 42 of the support guide mechanism 4 on the fixed frame 2 side is connected to a moving block 41 assembled to the track rail 40, and a large pressing force or pulling force is applied to the support leg 42. It is possible to smoothly move on the fixed frame 2 even when the action is applied.
　従って、本発明によれば、前記固定フレーム２と前記可動フレーム３との間に前記支持案内機構４及び復元部材５さえ設ければ、前記可動フレーム３のロッキングを防止しつつ、当該可動フレーム３を前記固定フレーム２に対して円滑に上下動させることができ、しかも前記案内ユニット４及び復元部材５は前記固定フレーム２と前記可動フレーム３の間に配置できるため、小型且つ軽量で、取り扱いの容易な上下免震装置を提供することが可能となる。 Therefore, according to the present invention, as long as the support guide mechanism 4 and the restoring member 5 are provided between the fixed frame 2 and the movable frame 3, the movable frame 3 is prevented from being locked while being prevented from locking. Can be smoothly moved up and down with respect to the fixed frame 2, and the guide unit 4 and the restoring member 5 can be disposed between the fixed frame 2 and the movable frame 3. An easy vertical seismic isolation device can be provided.
　図５は本発明を適用した免震装置の第二実施形態を示す正面図である。 FIG. 5 is a front view showing a second embodiment of the seismic isolation device to which the present invention is applied.
　この第二実施形態の免震装置１０では、前記支持案内機構４が前記固定フレーム２と前記可動フレーム３の間に複数配置されている。また、一対の支持案内機構４ａ，４ｂがコネクティングロッド６によって連結されて一組の案内ユニット７を構成しており、前記固定フレーム２と前記可動フレーム３の間には前記案内ユニット７が複数配置されている。尚、前述の第一実施形態と同一の構成については、図中に第一実施形態と同一の符号を付し、ここではそれらの詳細な説明は省略する。 In the seismic isolation device 10 of the second embodiment, a plurality of the support guide mechanisms 4 are disposed between the fixed frame 2 and the movable frame 3. A pair of support guide mechanisms 4 a and 4 b are connected by a connecting rod 6 to constitute a pair of guide units 7, and a plurality of guide units 7 are arranged between the fixed frame 2 and the movable frame 3. Has been. In addition, about the structure same as above-mentioned 1st embodiment, the code | symbol same as 1st embodiment is attached | subjected in a figure, and those detailed description is abbreviate | omitted here.
　前記案内ユニット７は、一対の支持案内機構４ａ，４ｂと、これら一対の支持案内機構４ａ，４ｂの動きを同期させるコネクティングロッド６とを含んでいる。前記コネクティングロッド６によって連結された一対の支持案内機構４ａ，４ｂは、各支持案内機構に含まれる前記支持脚４２が前記固定フレーム２上において同一方向へ傾斜しており、また、前記軌道レール４０が前記固定フレーム２上において一直線状に配置されている。すなわち、前記支持案内機構４ａの支持脚４２の運動平面は、前記支持案内機構４ｂの支持脚４２の運動平面と重なっている。 The guide unit 7 includes a pair of support guide mechanisms 4a and 4b and a connecting rod 6 for synchronizing the movements of the pair of support guide mechanisms 4a and 4b. In the pair of support guide mechanisms 4a and 4b connected by the connecting rod 6, the support legs 42 included in each support guide mechanism are inclined in the same direction on the fixed frame 2, and the track rail 40 Are arranged in a straight line on the fixed frame 2. That is, the motion plane of the support leg 42 of the support guide mechanism 4a overlaps the motion plane of the support leg 42 of the support guide mechanism 4b.
　前記コネクティングロッド６は、前記案内ユニット７に含まれる一対の支持案内機構４ａ，４ｂの連結点Ｄ同士を連結している。すなわち、前記コネクティングロッド６の一端は一方の支持案内機構４ａの連結点Dに対して回転自在に連結される一方、他端は他方の支持案内機構４ｂの連結点Ｄに対して回転自在に連結されている。従って、前記コネクティングロッド６は一方の支持案内機構４ａの連結点Dと他方の支持案内機構４ｂの連結点Ｄの間隔を一定に保持している。尚、前記コネクティングロッド６は一対の支持案内機構４ａ，４ｂの支持脚４２の相対応する部位に対して回転自在に連結されるのであれば、連結点Ｄに連結される必要はない。 The connecting rod 6 connects the connection points D of the pair of support guide mechanisms 4a and 4b included in the guide unit 7. That is, one end of the connecting rod 6 is rotatably connected to a connection point D of one support guide mechanism 4a, while the other end is rotatably connected to a connection point D of the other support guide mechanism 4b. Has been. Accordingly, the connecting rod 6 keeps the distance between the connection point D of one support guide mechanism 4a and the connection point D of the other support guide mechanism 4b constant. The connecting rod 6 does not need to be connected to the connection point D if it is rotatably connected to the corresponding portions of the support legs 42 of the pair of support guide mechanisms 4a and 4b.
　このため、図５中の紙面右側に位置する支持案内機構４ａにおいて連結点Ａを下方へ押し下げると、前記コネクティングロッド６が図３中の紙面左側に位置する支持案内機構４ｂの連結点Ｄを図３中の紙面右方向へ引っ張る結果となり、左側の支持案内機構４ｂにおいても連結点Ａが右側の支持案内機構４ａと同じ距離だけ下降することになる。つまり、前記コネクティングロッド６は前記案内ユニット７に含まれる一対の支持案内機構４ａ，４ｂの動きを同期させる働きをしている。 For this reason, when the connection point A is pushed downward in the support guide mechanism 4a located on the right side in FIG. 5, the connecting rod 6 shows the connection point D of the support guide mechanism 4b located on the left side in FIG. As a result, the connecting point A is lowered by the same distance as that of the right support guide mechanism 4a in the left support guide mechanism 4b. That is, the connecting rod 6 functions to synchronize the movements of the pair of support guide mechanisms 4 a and 4 b included in the guide unit 7.
　これにより、前記コネクティングロッド６で連結された一対の支持案内機構４ａ，４ｂでは、前記可動フレーム３と前記支持脚４２との連結点Ａの高さが常に同一となり、固定フレーム２上における可動フレーム３のロッキングを防止しながら、当該可動フレーム３を自由に上下動させることが可能となっている。 Thereby, in the pair of support guide mechanisms 4a and 4b connected by the connecting rod 6, the height of the connection point A between the movable frame 3 and the support leg 42 is always the same, and the movable frame on the fixed frame 2 is fixed. The movable frame 3 can be freely moved up and down while preventing the locking of 3.
　図６は前記固定フレーム２と前記可動フレーム３の間における前記案内ユニット７の配置を示す平面図であり、前記可動フレーム３を取り除いた状態を示している。この図６の例では四基の案内ユニット７Ａ，７Ｂ，７Ｃ，７Ｄが配置されており、二基の案内ユニット７Ａ，７ＣはＸ方向に沿って互いに逆向きに、二基の案内ユニット７Ｂ，７ＤはＹ方向に沿って互いに逆向きに配置されている。すなわち、各案内ユニット７Ａ，７Ｂ，７Ｃ，７Ｄに含まれる前記支持脚４２の傾斜方向は当該案内ユニット毎に異なっている。また、前記案内ユニット７Ａ，７Ｃでは前記支持案内機構４ａ，４ｂに含まれる軌道レール４０は長手方向をＸ方向に合致して敷設されており、前記案内ユニット７Ｂ，７Ｄでは前記支持案内機構４ａ，４ｂに含まれる軌道レール４０は長手方向をY方向に合致して敷設されている。 FIG. 6 is a plan view showing the arrangement of the guide unit 7 between the fixed frame 2 and the movable frame 3, and shows a state where the movable frame 3 is removed. In the example of FIG. 6, four guide units 7A, 7B, 7C, and 7D are arranged, and the two guide units 7A and 7C are opposite to each other along the X direction, 7D is arrange | positioned mutually reversely along the Y direction. That is, the inclination direction of the support leg 42 included in each guide unit 7A, 7B, 7C, 7D is different for each guide unit. In the guide units 7A and 7C, the track rails 40 included in the support guide mechanisms 4a and 4b are laid so that the longitudinal direction coincides with the X direction. In the guide units 7B and 7D, the support guide mechanisms 4a The track rail 40 included in 4b is laid with its longitudinal direction coinciding with the Y direction.
　この第二実施形態の免震装置によれば、前記固定フレーム２と前記可動フレーム３との間に複数の支持案内機構４を配置すると共に、各支持案内機構４の動きを同期させることができ、前記可動フレーム３の面積が大きい場合であっても、ロッキングを防止しながら、当該可動フレーム３を自由に上下動させることが可能である。 According to the seismic isolation device of the second embodiment, a plurality of support guide mechanisms 4 can be arranged between the fixed frame 2 and the movable frame 3, and the movements of the support guide mechanisms 4 can be synchronized. Even when the area of the movable frame 3 is large, it is possible to freely move the movable frame 3 up and down while preventing locking.
　尚、前記固定フレーム２と前記可動フレーム３との間に配置される案内ユニット４の基数及びそれらの配置は図６に示す例に限定されるものではなく、例えば三基以上の案内ユニット４を前記可動フレーム３の中心を基準として放射状に等間隔で配置しても良い。 The number of guide units 4 arranged between the fixed frame 2 and the movable frame 3 and the arrangement thereof are not limited to the example shown in FIG. 6. For example, three or more guide units 4 are provided. You may arrange | position radially at equal intervals on the basis of the center of the said movable frame 3. FIG.
　図７は本発明を適用した免震装置の第三実施形態を示す斜視図である。 FIG. 7 is a perspective view showing a third embodiment of the seismic isolation device to which the present invention is applied.
　この第三実施形態の免震装置１１では、前記固定フレーム２と前記可動フレーム３の間に四基の前記支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄが配置されている。前記免震装置１１を複数台連結して使用することを想定し、前記固定フレーム２及び前記可動フレーム３は正方形状に形成されている。各支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄは前記固定フレーム３の中心の周囲に放射状に配置されており、前記軌道レール４０の長手方向が前記固定フレーム２の外縁の各辺と９０度の角度をなしている。尚、前述の第一実施形態と同一の構成については、図中に第一実施形態と同一の符号を付し、ここではそれらの詳細な説明は省略する。 In the seismic isolation device 11 according to the third embodiment, the four support guide mechanisms 4A, 4B, 4C, and 4D are arranged between the fixed frame 2 and the movable frame 3. Assuming that a plurality of the seismic isolation devices 11 are connected and used, the fixed frame 2 and the movable frame 3 are formed in a square shape. The support guide mechanisms 4A, 4B, 4C, 4D are arranged radially around the center of the fixed frame 3, and the longitudinal direction of the track rail 40 is 90 degrees with each side of the outer edge of the fixed frame 2. I am doing. In addition, about the structure same as above-mentioned 1st embodiment, the code | symbol same as 1st embodiment is attached | subjected in a figure, and those detailed description is abbreviate | omitted here.
　前記復元部材５は第一実施形態と同様に所謂ねじりばねから構成されており、各支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄとの干渉を避けるため、前記固定フレーム２の四隅に対応して配置され、一方の腕部５０は前記可動フレーム３に、他方の腕部５１は前記固定フレーム２に対して夫々回転自在に連結されている。 Similarly to the first embodiment, the restoring member 5 is constituted by a so-called torsion spring, and is arranged corresponding to the four corners of the fixed frame 2 in order to avoid interference with the support guide mechanisms 4A, 4B, 4C, 4D. One arm portion 50 is rotatably connected to the movable frame 3 and the other arm portion 51 is rotatably connected to the fixed frame 2.
　また、各支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄにはダンパが設けられている。当該ダンパは前記可動フレーム３の上下動に対して反力を及ぼし、前記可動フレーム３に生じる上下振動を早期に収束させる。この第三実施形態では前記ダンパとして回転型の摩擦ダンパ８を用いており、各支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄの移動ブロック４１に対して前記摩擦ダンパ８を固定している。前記摩擦ダンパ８の回転軸にはピニオンギヤが設けられており、当該ピニオンギヤは各支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄの軌道レール４０と平行に設けられたラック８０と噛み合っている。 Also, each support guide mechanism 4A, 4B, 4C, 4D is provided with a damper. The damper exerts a reaction force on the vertical movement of the movable frame 3 and converges the vertical vibration generated in the movable frame 3 at an early stage. In the third embodiment, a rotary friction damper 8 is used as the damper, and the friction damper 8 is fixed to the moving block 41 of each support guide mechanism 4A, 4B, 4C, 4D. The rotation shaft of the friction damper 8 is provided with a pinion gear, and the pinion gear meshes with a rack 80 provided in parallel with the track rail 40 of each of the support guide mechanisms 4A, 4B, 4C, 4D.
　このため、前記可動フレーム３が上下動し、前記支持脚４２に連結された前記移動ブロック４１が前記軌道レール４０上を移動すると、前記摩擦ダンパ８が回転して、前記移動ブロック４１の運動に対して反力が作用する。これにより、前記可動フレーム３の上下動に対しては常に当該上下動を抑制する方向の反力が作用することになり、当該可動フレーム３の上下振動を早期に収束することが可能である。 For this reason, when the movable frame 3 moves up and down and the moving block 41 connected to the support leg 42 moves on the track rail 40, the friction damper 8 rotates, and the moving block 41 moves. On the other hand, a reaction force acts. Accordingly, a reaction force in a direction to suppress the vertical movement always acts on the vertical movement of the movable frame 3, and the vertical vibration of the movable frame 3 can be converged at an early stage.
　図８は前記固定フレーム２上における四基の支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄの配置を示す平面図であり、前記可動フレーム３及び前記復元部材５を取り外した状態を示している。四基の支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄは正方形に形成された固定フレーム２の中心の周囲に均等に配置されている。但し、前記固定フレーム２の中心を挟んで対向する一対の支持案内機構は一直線上には配置されておらず、各支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄは前記固定フレーム２の中心に対して変位した位置に設けられている。すなわち、図８中に示すように、各支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄの支持脚４２がリンクとして動作する運動平面は前記固定フレーム２の中心に対して距離dだけ変位した位置に
存在している。 FIG. 8 is a plan view showing the arrangement of the four support guide mechanisms 4A, 4B, 4C, and 4D on the fixed frame 2, and shows a state where the movable frame 3 and the restoring member 5 are removed. The four support guide mechanisms 4A, 4B, 4C, 4D are evenly arranged around the center of the fixed frame 2 formed in a square shape. However, the pair of support guide mechanisms opposed across the center of the fixed frame 2 are not arranged in a straight line, and each of the support guide mechanisms 4A, 4B, 4C, 4D is located with respect to the center of the fixed frame 2. It is provided at the displaced position. That is, as shown in FIG. 8, the motion plane in which the support leg 42 of each support guide mechanism 4A, 4B, 4C, 4D operates as a link exists at a position displaced by a distance d with respect to the center of the fixed frame 2. is doing.
　この第三実施形態の免震装置１１は複数台を連結して使用することができ、前記可動フレーム３上に載置する免震対象物の大きさに応じて任意の台数の免震装置１１を連結して、前記免震装置１１の集合体である免震装置ユニットを構成することが可能である。隣接する二台の免震装置１１を連結する場合には、第二実施形態で示したコネクティングロッド６を使用し、各免震装置１１に配置された四基の支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄのうち、対応する一対の支持案内機構を前記コネクティングロッド６で連結する。 The seismic isolation device 11 of this third embodiment can be used by connecting a plurality of units, and any number of seismic isolation devices 11 can be used depending on the size of the seismic isolation object placed on the movable frame 3. It is possible to configure a seismic isolation device unit that is an assembly of the seismic isolation devices 11. When connecting two adjacent seismic isolation devices 11, the connecting rod 6 shown in the second embodiment is used, and the four support guide mechanisms 4A, 4B, 4C arranged in each seismic isolation device 11 are used. , 4D, a pair of corresponding support guide mechanisms are connected by the connecting rod 6.
　図９は六台の免震装置１１を連結して免震装置ユニット１２を構成した例を示すものである。図中に斜線で示している部材が前記コネクティングロッド６である。前記コネクティングロッド６は複数の支持案内機構のうち、同じ方向へ傾斜する支持脚４２を有する一対の支持案内機構を連結しており、例えば支持案内機構４Ａ同士、支持案内機構４Ｂ同士、支持案内機構４Ｃ同士、支持案内機構４Ｄ同士を連結している。支持案内機構４Ａ同士又は支持案内機構４Ｃ同士を連結するコネクティングロッドはＹ方向に沿って設けられ、支持案内機構４Ｂ同士又は支持案内機構４Ｄ同士を連結するコネクティングロッド６はＸ方向に沿って設けられている。 FIG. 9 shows an example in which six seismic isolation devices 11 are connected to form a seismic isolation device unit 12. The member shown by oblique lines in the figure is the connecting rod 6. The connecting rod 6 connects a pair of support guide mechanisms having support legs 42 inclined in the same direction among the plurality of support guide mechanisms. For example, the support guide mechanisms 4A, the support guide mechanisms 4B, and the support guide mechanisms. 4C and support guide mechanism 4D are connected. The connecting rods that connect the support guide mechanisms 4A or the support guide mechanisms 4C are provided along the Y direction, and the connecting rods 6 that connect the support guide mechanisms 4B or the support guide mechanisms 4D are provided along the X direction. ing.
　このように免震装置１１を連結して使用する際、既に説明したように、各免震装置１１の支持案内機構４Ａ，４Ｂ，４Ｃ，４Ｄは前記固定フレーム２の中心に対して変位して設けられているので、例えば、前記支持案内機構４Ａ同士を連結するコネクティングロッド６が前記支持案内機構４Ｃ同士を連結するコネクティングロッド６と干渉することはなく、Ｙ方向に延びる二本のコネクティングロッド６を平行に配置することが可能となる。また、前記支持案内機構４Ｂ同士を連結するコネクティングロッド６が前記支持案内機構４Ｄ同志を連結するコネクティングロッド６と干渉することはなく、Ｘ方向に延びる二本のコネクティングロッド６を平行に配置することが可能となる。 When the seismic isolation device 11 is connected and used as described above, the support guide mechanisms 4A, 4B, 4C, and 4D of the seismic isolation devices 11 are displaced with respect to the center of the fixed frame 2 as described above. For example, the connecting rods 6 that connect the support guide mechanisms 4A do not interfere with the connecting rods 6 that connect the support guide mechanisms 4C, and the two connecting rods 6 extend in the Y direction. Can be arranged in parallel. In addition, the connecting rods 6 that connect the support guide mechanisms 4B do not interfere with the connecting rods 6 that connect the support guide mechanisms 4D, and the two connecting rods 6 extending in the X direction are arranged in parallel. Is possible.
　これにより、複数台の免震装置１１を連続的に連結して、免震対象物の大きさに合致した免震装置ユニット１２を組み立てることが可能となる。また、前記コネクティングロッド６で連結された一対の支持案内機構は動きが同期しているので、いずれか一台の免震装置１１の可動フレーム３が押し下げられると、それに呼応して残るすべての免震装置１１の可動フレーム３が押し下げられることになる。従って、免震装置の連結台数が多い場合であっても、ロッキングを防止しながら、すべての可動フレーム３を自由に上下動させることが可能である。 This makes it possible to continuously connect a plurality of seismic isolation devices 11 and assemble a seismic isolation device unit 12 that matches the size of the seismic isolation object. In addition, since the movement of the pair of support guide mechanisms connected by the connecting rod 6 is synchronized, when the movable frame 3 of any one of the seismic isolation devices 11 is pushed down, all the remaining reliefs corresponding to it are responded. The movable frame 3 of the seismic device 11 is pushed down. Therefore, even when the number of connected seismic isolation devices is large, all the movable frames 3 can be freely moved up and down while preventing locking.
尚、前述の第三実施形態では前記可動フレーム３の上下振動を収束させるダンパとして摩擦ダンパを用いたが、本発明の免震装置に使用し得るダンパはこれに限られるものではなく、粘性ダンパやマスダンパ等の各種ダンパを使用することが可能である。特に、マスダンパは前記可動フレーム３に発生する振動の固有周期を長周期化できるという利点があり、当該マスダンパを粘性ダンパや摩擦ダンパと併用してもよい。 In the third embodiment described above, a friction damper is used as a damper for converging the vertical vibration of the movable frame 3, but the damper that can be used in the seismic isolation device of the present invention is not limited to this, and a viscous damper is used. It is possible to use various dampers such as mass dampers. In particular, the mass damper has an advantage that the natural period of vibration generated in the movable frame 3 can be increased, and the mass damper may be used in combination with a viscous damper or a friction damper.
　また、前記ダンパの取付位置は前記可動フレームの上下振動に対して反力を及ぼすことが可能であれば、適宜変更することが可能であり、例えば、前記可動フレーム３に対して前記ダンパを直接連結しても良いし、図４に示す復元部材５のように、前記支持案内機構４の支持脚４２と補助脚４３の間に前記ダンパを配置しても良い。 Further, the mounting position of the damper can be appropriately changed as long as a reaction force can be exerted on the vertical vibration of the movable frame. For example, the damper is directly attached to the movable frame 3. The damper may be disposed between the support leg 42 and the auxiliary leg 43 of the support guide mechanism 4 as in the restoring member 5 shown in FIG.
