Description

【０００１】
本発明は、ポンプ装置で発生した振動が台座に伝達されるのを防止する防振部材を配設したポンプ装置の防振取り付け機構に関する。
【０００２】
【従来の技術】
例えば医療用分野において、内視鏡を用いて診断あるいは治療・処置を行う場合、内視鏡検査に必要な内視鏡や光源装置、送気・送水装置、ビデオプロセッサなど周辺装置を作業性を向上させるためにラックなどにひとまとめに搭載して内視鏡システムを構成していた。
【０００３】
近年、診断及び操作性をより一層向上させるため、各周辺装置をユニット化してシステム用筐体に集約し、メインの制御装置で各装置の制御を行えるようにした内視鏡システムも提案されている。
【０００４】
これら内視鏡システムで使用される送気・送水装置には気体または流体を供給する働きを行なうポンプ装置が設けられている。これらポンプ装置にはシリンダの壁面に沿ってピストンが往復運動する往復ポンプや羽根車の付いたランナーがケーシングの中で高速回転する遠心ポンプなどがあり、このポンプ装置が送気・送水装置の構成部の１つとしてシステム内に配設されている。
【０００５】
前記ポンプ装置を台座などの取り付け部に固定する際にはポンプ装置から発生する振動が取り付け部に伝達されることを防止するため、台座上に防振部材を設置し、この防振部材上にポンプ装置を載置して防振構造としていた。このことにより、ポンプ装置で発生した振動が台座に伝達されることを防止していた。
【０００６】
また、上述のようにポンプ装置を防振部材上に載置する防振構造の他に、台座を防振部材で挟持し、この防振部材で挟持された台座にポンプ装置を配置し、ビスやボルトなどでポンプ装置を台座に一体的に固定する防振構造がとられていた。このことにより、このポンプ装置で発生した振動が台座に伝達されることが防止されると共に、ポンプ装置が台座に確実に固定される。
【０００７】
【発明が解決しようとする課題】
しかしながら、ポンプ装置を防振部材上に載置した構造では地震時や輸送時などに位置ずれや転倒するおそれがあるので、設置あるいは輸送に際しては特別な固定手段を設ける必要があった。
【０００８】
一方、ポンプ装置を、防振部材で挟持された台座に配置し、このポンプ装置と台座とをビスやボルトで一体的に固定した場合、台座の下面より防振部材が突出してしまう。このため、台座下面より突出する防振部材を配置するための空間部が十分でないときにはポンプ装置を設置することができなくなり、ポンプ装置を設置するためには台座の下面より突出する防振部材の厚みを薄くしなければならず、このことにより防振構造を十分に保持することが困難になるおそれがあった。
【０００９】
本発明は上記事情に鑑みてなされたものであり、台座下面部のスペース的制約を受けることなく、ポンプ装置を確実に台座に固定する一方、このポンプ装置で発生する振動が台座に伝達させることを防止するポンプ装置の防振取り付け機構を提供することを目的としている。
【００１０】
【課題を解決するための手段】
本発明のポンプ装置の防振取り付け機構は、設置されるポンプ装置の脚部の底面に対向する位置に形成された台座孔部を有する、当該ポンプ装置を設置するための台座と、前記台座の上面と前記ポンプ装置の脚部の底面との間に挟設されると共に、前記ポンプ装置の脚部に対向する位置に上面から底面にかけて貫通孔を形成した防振部材と、前記防振部材を前記台座に対して固定するための部材であって、当該防振部材の上面に覆接する上壁部と、前記上壁部から曲折して延設され同防振部材の側面に覆接する側壁部と、前記側壁部から曲折して延設され前記台座上面に当接する翼部と、前記上壁部における前記脚部の底面に対向する位置に形成された脚部逃用孔部と、を有した防振部材固定部材と、前記防振部材固定部材における前記翼部を前記台座上面に固定するための防振部材固定部材固定手段と、前記防振部材が前記台座上面に配設された際、前記台座孔部に露呈する当該防振部材の前記貫通孔に底面側から挿入し、当該防振部材を前記ポンプ装置の脚部に対して当接固定するための脚部固定手段と、を具備したことを特徴とする。
【００１１】
この構成によれば、ポンプ装置に一体的に固定されている防振部材を、固定手段を介して台座に固定して、ポンプ装置を台座に固定しているので、ポンプ装置で発生する振動が台座に伝達されることなく、且つ、ポンプ装置が確実に台座に固定される。また、ポンプ装置を台座に固定する際に、台座下部のスペースに制約を受け無い。
【００１２】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を説明する。
図１ないし図３は本発明の一実施形態に係り、図１はポンプ装置の台座への固定状態を示す説明図、図２はポンプ装置の台座への取り付け構造を示す説明図、図３は図２のＡ−Ａ断面図である。
【００１３】
図１に示すように本実施形態のポンプ装置１は、取り付け部である台座２に、所定の厚みに設定した例えばゴム製で振動を吸収する防振部材３を固定手段を構成する防振部材固定部材（以下、防振固定部材と略記）４に収容し、この防振固定部材４を固定手段であるビス５で台座２に螺合固定することによって、一体的に固定されている。このとき、ポンプ装置１の脚部６が防振部材３の上に設置された状態になっている。
【００１４】
即ち、図２及び図３に示すように固定手段を構成する前記防振固定部材４の中央凸部の箱状空間部内に、前記防振部材３を上下面以外の４面方向へ動くことがないように隙間無く収容し、この防振部材３を収容した防振固定部材４を、固定手段を構成する前記ビス５で台座２に螺合固定して、前記ポンプ装置１を台座２に一体的に固定している。
【００１５】
前記防振固定部材４は、略凸字形状をしており、箱状空間部を形成する中央凸部の上面中央部にはポンプ装置１の脚部６と防振固定部材４とが接触して振動がこの防振固定部材４に伝達されることを防止する前記脚部６より大径の脚部逃がし用透孔８が形成され、この防振固定部材４の両翼部４ａには前記ビス５を挿通するビス用透孔４ｂが形成されている。
【００１６】
前記防振部材３は、前記防振固定部材４の箱状空間部内に隙間無く収容されるように略直方体形状をしている。図３に示すように前記防振部材３の略中央部には、この防振部材３をポンプ装置１の脚部６に一体的に固定するための固定部材である固定ネジ７が挿通するネジ用透孔３ａが設けられている。そして、前記脚部６底面の略中央部で前記防振部材３に設けたネジ用透孔３ａに対向する位置には前記固定ネジ７が螺合するネジ部６ａが形成されている。なお、防振部材３の厚み寸法は、この防振部材３と台座２とが必ず接触するように、前記防振固定部材４の箱状空間部の深さ寸法より大きく形成してある。
【００１７】
前記台座２には前記防振固定部材４のビス用透孔４ｂに対応するように前記ビス５が螺合するネジ部（不図示）が設けられている。また、この台座２の前記固定ネジ７の頭部が対応する位置には防振部材３を脚部６に一体的に固定する止めネジ７と台座２とが接触して振動が台座２に伝達されることを防止する前記固定ネジ７の頭部より大径の固定ネジ逃がし用透孔９が形成されている。
【００１８】
ここで、ポンプ装置１の台座２への取り付け構造を説明する。
まず、防振固定部材４の箱状空間部に防振部材３を収容する。
【００１９】
次に、前記防振部材３の上面に前記防振固定部材４の脚部逃がし用透孔８を介してポンプ装置１の脚部６を配置する。そして、固定ネジ７をネジ用透孔３ａに挿通し、この固定ネジ７を脚部６に設けたネジ部６ａに螺合させて、防振部材３をポンプ装置１の脚部６に一体的に固定する。
【００２０】
次いで、前記ポンプ装置１に一体的に固定されている防振部材３を収容している防振固定部材４を台座２の所定位置に配置し、前記防振固定部材４の翼部４ａのビス用透孔４ｂにビス５を挿通し、このビス５を台座２のネジ部に螺合して防振固定部材４を台座２に固定する。このことによって、前記ポンプ装置１の台座２への固定が終了してポンプ装置１が台座２に一体的に固定される。
【００２１】
なお、このとき、防振固定部材４に設けた脚部逃がし用透孔８によってポンプ装置１の脚部６と防振固定部材４とは互いに接触していない。また、台座２に設けた固定ネジ逃がし用透孔９によって前記防振部材３を脚部６に一体的に固定している止めネジ７と台座２とは互いに接触していない。
【００２２】
このため、ポンプ装置１の駆動中に発生する振動は、台座２と防振固定部材４との間に固定されている防振部材３に吸収されて台座２に伝達されない。
【００２３】
このように、ポンプ装置の脚部と防振部材固定部材とが接触することを防止する脚部逃がし用透孔を防振部材固定部材に設け、防振部材を脚部に固定する止めネジと台座とが接触することを防止する固定ネジ逃がし用透孔を台座に設け、ポンプ装置の脚部に一体的に固定した防振部材を収容している防振部材固定部材を台座にビスで固定することにより、ポンプ装置と台座とを直接接触させることなく、防振部材を介して、ポンプ装置と台座とを確実に固定することができる。このことにより、ポンプ装置で発生した振動が防振部材に吸収されて台座に伝達されることがなくなるばかりでなく、ポンプ装置と台座とが確実に固定されて、輸送時や地震時などにポンプ装置が台座から位置ずれすることや転倒することが防止される。
【００２４】
また、前記ポンプ装置の脚部に一体的に固定した防振部材を収容している防振部材固定部材を台座にビスで固定して、防振部材を介してポンプ装置と台座とを固定することにより、台座の下面から防振部材を脚部に一体的に固定する止めネジの頭部と防振部材固定部材を台座に固定するビスの先端部とだけを突出させた状態でポンプ装置を台座に固定することができる。このことにより、台座下面のスペース的制約を受けることがない。
【００２５】
なお、本実施形態においては、防振部材３とポンプ装置１の脚部６との固定に固定部材として止めネジ７を用いているが、防振部材３の脚部６への固定は止めネジによる固定に限定されるものではなく、ポンプ装置１の脚部６と防振固定部材４とが接触することなく確実に固定することが可能であれば、接着剤による固定などであってもよい。
【００２６】
また、防振固定部材４の箱状空間部及びこの箱状空間部に収容される防振部材３の形状は、箱状（略直方体）形状に限定されるものではなく、防振固定部材４の空間部形状と防振部材３の外形形状とが略同一で隙間無く収容可能な形状であれば、円柱形状や、多角形状などであってもよい。
【００２７】
さらに、固定手段である略凸字形状の防振固定部材４の代わりに、図４に示すような板状の防振固定部材２１を形成してもよい。この防振固定部材２１には、ポンプ装置１の脚部６より大径の脚部逃がし用透孔２２を設けると共に、防振部材２３をこの防振固定部材２１と台座２との間に配置するための止めネジ２４を挿通するネジ用透孔２１ａを設けている。そして、止めネジ２４をネジ用透孔２１ａに挿通して台座２のネジ部に螺合固定することにより、防振部材２３を防振固定部材２１と台座２とで挟持固定している。このことにより、上記実施形態の作用及び効果を得ることができるばかりでなく、防振固定部材２１の形状を簡素化して、部品コストの低減及び加工性の向上を図ることができる。また、防振固定部材２１と防振部材２３との形状を互いに合致させる制約を受けることがないので、両者の形状を合致させる手間を省くこともできる。なお、上述の実施形態と同様にポンプ装置１の脚部６と防振部材２３とを止めネジ７によらず、接着剤などによって固定するようにしてもよい。
【００２８】
またさらに、前記防振固定部材４及び防振固定部材２１の代わりに、図５に示すようにポンプ装置１の脚部６より大径の脚部逃がし用透孔３２と止めネジ３４を挿通するネジ用透孔３１ａを有する板状の防振固定部材３１を形成すると共に、前記防振部材３３に前記止めネジ３４が挿通するネジ用透孔３３ａを設けている。そして、固定部材３１と台座２との間に防振部材３３を配置してポンプ装置１を台座２に固定する際、止めネジ３４を固定部材３１のネジ用透孔３１ａと防振部材３３のネジ用透孔３３ａに挿通して台座２のネジ部に螺合固定することにより、防振部材２３を防振固定部材２１と台座２とで挟持固定している。このことにより、上記実施形態の作用及び効果を得ることができる。なお、上述の実施形態と同様にポンプ装置１の脚部６と防振部材３３とを止めネジ７によらず、接着剤などによって固定するようにしてもよい。
【００２９】
ところで、ポンプ装置をシステム用筐体に内蔵させて内視鏡システムを構成する場合、ポンプ装置の防振構造としてはシステム用筐体内の台座上に防振部材を配置し、この防振部材上にポンプ装置を置く構造が一般的である。このように、ポンプ装置を防振部材を介してシステム用筐体内の台座上に載置することにより、ポンプ装置から発生する振動がシステム用筐体やシステム内の他の装置などに伝達されないようになっている。また、内視鏡システムのシステム用筐体内の台座を防振部材で挟持し、この台座にポンプ装置をビス止めで固定する構造が知られている。ポンプ装置が台座に固定されると共に、ポンプ装置から発生する振動がシステム用筐体やシステム内の他の装置などに伝達されないようになっている。
【００３０】
しかし、防振部材を挟持した台座にポンプ装置を固定する際、システム筐体内の台座下部のスペース的制約を受ける。また、ポンプ装置を台座上に載置しているだけでは輸送の際や地震の際にポンプ装置が位置ずれしたり、転倒したりするおそれがある。このため、システム筐体内の台座下部のスペース的制約を受けることなく、確実にポンプ装置をシステム用筐体内の台座に固定でき、輸送時や地震時などに位置ズレや転倒のおそれのない内視鏡システムへのポンプ装置の防振取り付け構造が望まれていた。
【００３１】
図６に示すように本実施形態では内視鏡システムを構成するシステム用筐体４１にポンプ装置設置部４２を設けている。そして、このポンプ装置設置部４２に上述の実施形態で示したようにポンプ装置１の脚部６と防振固定部材４とが接触することを防止する脚部逃がし用透孔８を防振固定部材４に設け、防振部材３を脚部６に固定する止めネジ（不図示）とポンプ装置設置部４２とが接触することを防止する固定ネジ逃がし用透孔（不図示）をポンプ装置設置部４２に設け、ポンプ装置１の脚部６に一体的に固定した防振部材３を収容している防振固定部材４をポンプ装置設置部４２にビス５で固定することにより、ポンプ装置１とポンプ装置設置部４２とを直接接触させることなく防振部材３を介して、ポンプ装置１を台座２に固定するように、前記ポンプ装置設置部４２に固定している。
【００３２】
なお、本実施形態の内視鏡システムには、内視鏡検査の際に必要な光源装置やビデオプロセッサなどの各種周辺機器を内蔵しており、ポンプ装置１が上述のようにシステム用筐体４１内のポンプ装置設置部４２に固定されている。
【００３３】
また、ポンプ装置１には図示しない吸引ボトル、吸引チューブなどが接続されて吸引装置を構成しており、図示しない内視鏡の吸引チャンネルに連通している。
【００３４】
このように、ポンプ装置をシステム用筐体に設けたポンプ装置設置部に固定することにより、ポンプ装置で発生した振動がポンプ装置設置部に伝達されないため、システム用筐体が振動することが防止される。
【００３５】
また、ポンプ装置が確実にポンプ装置設置部に固定されているため、輸送時、地震時などの振動でポンプ装置がポンプ装置設置部から位置ずれしたり、転倒することがない。
【００３６】
なお、ポンプ装置のポンプ装置設置部への取り付け構造は前記図４及び図５に示したポンプ装置を台座に固定する構造であってもよいことはいうまでもなく、これらの取り付け構造でも同様の作用及び効果を得ることができる。

The present invention relates to an anti- vibration mounting mechanism for a pump device provided with an anti-vibration member for preventing vibration generated in the pump device from being transmitted to a pedestal.
[0002]
[Prior art]
For example, in the medical field, when performing diagnosis, treatment, or treatment using an endoscope, the peripheral devices such as an endoscope, light source device, air / water supply device, and video processor that are necessary for endoscopy are improved. In order to improve it, the endoscope system was configured by mounting it on a rack together.
[0003]
In recent years, in order to further improve diagnosis and operability, an endoscope system has been proposed in which each peripheral device is unitized and integrated into a system housing so that the main control device can control each device. Yes.
[0004]
An air / water supply device used in these endoscope systems is provided with a pump device that performs a function of supplying a gas or a fluid. These pump devices include a reciprocating pump in which the piston reciprocates along the cylinder wall surface and a centrifugal pump in which a runner with an impeller rotates at a high speed in the casing. This pump device constitutes an air / water supply device. It is arranged in the system as one of the parts.
[0005]
In order to prevent vibration generated from the pump device from being transmitted to the mounting portion when the pump device is fixed to the mounting portion such as a pedestal, a vibration isolation member is installed on the pedestal, and the vibration isolation member is placed on the vibration isolation member. The pump device was placed to have a vibration-proof structure. Thus, vibration generated in the pump device is prevented from being transmitted to the pedestal.
[0006]
In addition to the anti-vibration structure in which the pump device is mounted on the anti-vibration member as described above, the pedestal is held by the anti-vibration member, and the pump device is disposed on the pedestal held by the anti-vibration member. An anti-vibration structure has been adopted in which the pump device is integrally fixed to the pedestal with bolts and bolts. As a result, vibration generated in the pump device is prevented from being transmitted to the pedestal, and the pump device is securely fixed to the pedestal.
[0007]
[Problems to be solved by the invention]
However, in the structure in which the pump device is mounted on the vibration isolating member, there is a risk of displacement or overturning at the time of an earthquake or transportation, and therefore it is necessary to provide a special fixing means for installation or transportation.
[0008]
On the other hand, when the pump device is arranged on a pedestal sandwiched between vibration isolating members and the pump device and the pedestal are integrally fixed with screws or bolts, the vibration isolating member protrudes from the lower surface of the pedestal. For this reason, it is impossible to install the pump device when there is not enough space for arranging the vibration isolating member protruding from the lower surface of the pedestal. To install the pump device, the vibration isolating member protruding from the lower surface of the pedestal is not provided. The thickness must be reduced, which may make it difficult to sufficiently hold the vibration-proof structure.
[0009]
The present invention has been made in view of the above circumstances, and allows the vibration generated by the pump device to be transmitted to the pedestal while securely fixing the pump device to the pedestal without being restricted by the space on the lower surface of the pedestal. An object of the present invention is to provide an anti-vibration mounting mechanism for a pump device that prevents the above-described problem.

According to this configuration, the vibration isolating member that is integrally fixed to the pump device is fixed to the pedestal via the fixing means, and the pump device is fixed to the pedestal. The pump device is securely fixed to the pedestal without being transmitted to the pedestal. Moreover, when fixing a pump apparatus to a base, there is no restriction | limiting in the space of a base lower part.
[0012]
