Description

本発明は、例えば空調装置等、振動の大きな設備機器を設置するための防振架台に関し、特に長尺状の架台ユニットを２つ並べて連結した構造のものに係る。 The present invention relates to a vibration isolator for installing equipment with large vibration such as an air conditioner, and particularly relates to a structure in which two long base units are connected side by side.

従来より、この種の防振架台としてはコストの低減を図るとともに、運搬時の利便性を考慮して分解できるように、その構成部材を溶接ではなく、ボルト等により締結する構造としたものがある。例えば特許文献１に記載のものでは、載架枠や基台枠を構成する枠材同士をコーナー部において突き合わせ、連結金具を介してネジにより締結するようにしている。 Conventionally, this type of anti-vibration mount has a structure in which its constituent members are fastened not by welding but by bolts so that it can be disassembled in consideration of convenience during transportation. is there. For example, in the thing of patent document 1, the frame materials which comprise a mounting frame and a base frame are faced | matched in a corner part, and it is made to fasten with a screw via a connection metal fitting.

しかし、前記文献に記載のものでは、載架枠及び基台枠の双方を矩形の枠状に構成しているため、全体として重量が嵩むことになり運搬時の利便性はあまり高いとは言えないし、設置場所での組み立てにも手間が掛かる。また、コストの削減も十分とは言い難い。 However, in the above-mentioned document, since both the mounting frame and the base frame are formed in a rectangular frame shape, the weight increases as a whole, and it can be said that convenience during transportation is very high. Also, it takes time to assemble at the installation location. Moreover, it is difficult to say that the cost reduction is sufficient.

この点、例えば特許文献２、３に開示されるように、長尺の架台ユニット（防振ユニット、レール形防振台）を横に並べて、その上に設備機器を搭載する構成とすれば、軽量で運搬しやすく、組み立てに手間の掛かることもないし、コストも大幅に削減可能である。 In this regard, for example, as disclosed in Patent Documents 2 and 3, if a long gantry unit (anti-vibration unit, rail-type anti-vibration table) is arranged side by side and equipment is mounted thereon, It is lightweight and easy to transport, does not require much time for assembly, and costs can be greatly reduced.

そうした場合に各架台ユニットの下架台（下部支持部材、基台）は、アンカーボルトによって基礎に固定することになり、一方、上架台（上部支持部材、架台）は機器の底部に固定することになるが、機器の底部は剛性の不足することもあるので、上架台同士の間には梁部材を架け渡して連結することが考えられる。 In such a case, the lower base (lower support member, base) of each base unit is fixed to the foundation with anchor bolts, while the upper base (upper support member, base) is fixed to the bottom of the device. However, since the bottom of the device may lack rigidity, it is conceivable that a beam member is bridged between the upper mounts.

しかしながら、前記後者の従来例（特許文献２、３）のように、一対の架台ユニットを並べたり、その上架台同士を梁部材によって連結しただけでは、架台ユニットがぐらつきやすく、設置作業が非常にやり難いという問題がある。例えば並べた架台ユニットの上に仮置きした機器を横にずらそうとすると、架台ユニットが捩れてぐらつくことになるし、下架台をアンカー固定する前であれば架台ユニットが倒れる心配もある。 However, as in the latter conventional example (Patent Documents 2 and 3), simply arranging a pair of gantry units or connecting the upper gantry units together with a beam member makes the gantry units easily wobble, and the installation work is extremely difficult. There is a problem that it is difficult. For example, if the device temporarily placed on the arranged gantry units is shifted laterally, the gantry unit is twisted and wobbles, and the gantry unit may fall before anchoring the lower gantry.

このような不具合は、前者の従来例のように下架台同士も梁部材によって連結する構造とすれば概ね解消できると思われるが、これでは重量やコストの削減が不十分になってしまい、組み立てにも手間の掛かることは上述した通りである。 Such inconveniences can be generally eliminated by using a structure in which the undercarriages are also connected by beam members as in the former conventional example, but this would result in insufficient weight and cost reduction, and assembly. However, as described above, it takes time and effort.

本発明は斯かる点に鑑みてなされたもので、長尺状の架台ユニットを横並びに設けた簡易な構造を基本とし、組み立ての手間が掛からず重量やコストを十分に削減できるものでありながら、ぐらつきが少なく設置作業の容易な防振架台を提供することにある。 The present invention has been made in view of such a point, and is based on a simple structure in which long gantry units are provided side by side, and it is possible to sufficiently reduce the weight and cost without taking assembling work. An object of the present invention is to provide an anti-vibration stand with little wobble and easy installation.

前記の目的を達成するために本発明では、一対の架台ユニットの上架台若しくは下架台同士を連結するように梁部材を設けるとともに、その両端部に上下それぞれの被嵌部を設けて、上架台及び下架台の双方に嵌め合わせるようにした。 In order to achieve the above object, in the present invention, a beam member is provided so as to connect an upper base or a lower base of a pair of base units, and upper and lower fitting portions are provided at both ends thereof, And it was made to fit on both the undercarriage.

すなわち、請求項１の発明は、各々長尺状の上架台及び下架台の間に防振体を介在させてなる一対の架台ユニットが、横並びに配設されるとともに、互いに対をなす上架台ないし下架台の両端部同士が梁部材によって連結されている防振架台を対象として、その梁部材の両端部にそれぞれ、上架台の端部の嵌合部に嵌め合わされる上被嵌部と、下架台の端部の嵌合部に嵌め合わされる下被嵌部と、を設けたものである。 That is, according to the first aspect of the present invention, a pair of gantry units each having a vibration isolator interposed between an elongated gantry and a lower gantry are arranged side by side, and the gantry is paired with each other. Or an anti-vibration mount in which both ends of the lower mount are connected to each other by a beam member, and an upper fitting portion that is fitted to the end of the upper mount on each end of the beam member; And a lower fitting portion that is fitted to the fitting portion at the end of the lower base.

斯かる構成の防振架台では、例えば上架台の両端部をぞれぞれ梁部材によって連結することで、全体として矩形の枠状として剛性を確保しやすいのみならず、その梁部材の端部には、上架台に嵌合する上被嵌部の他に下架台に嵌合する下被嵌部も設けられていて、これにより上下の架台同士が連結されているので、架台ユニットの捩れに対する剛性が高くなって、その倒れ防止が図られる。 In the anti-vibration mount having such a configuration, for example, by connecting both ends of the upper mount by beam members, it is easy to ensure rigidity as a rectangular frame as a whole, but also the end portions of the beam members In addition to the upper fitting part that fits into the upper frame, there is also provided a lower fitting part that fits into the lower frame, so that the upper and lower frames are connected to each other. The rigidity becomes high and the fall is prevented.

好ましくは、対をなす上架台の端部間に梁部材を直線的に架け渡すことであり、こうすれば、機器が直接、搭載される上架台の剛性を確保しやすい。そして、梁部材の両端部にはそれぞれ下方に延びる丸棒状の軸部を設けて、これを下架台の丸穴（嵌合部）に上方から嵌め込む構造とするのがよい（請求項２）。こうすれば、横並びに配置した一対の架台ユニットに対し梁部材を上方から容易に取り付けることができる。また、その軸部を中心として梁部材を水平方向に回動させることにより、架台ユニット同士を梁部材によって連結したままコンパクトに折り畳むことができるようになる。 Preferably, the beam member is linearly bridged between the ends of the pair of upper bases, and in this way, it is easy to ensure the rigidity of the upper base on which the device is directly mounted. And it is good for the both ends of a beam member to provide the structure which inserts this in the round hole (fitting part) of an undercarriage from the upper part by providing the round bar-shaped axial part extended below, respectively (Claim 2). . If it carries out like this, a beam member can be easily attached from upper direction with respect to a pair of base unit arranged side by side. Further, by rotating the beam member in the horizontal direction around the shaft portion, the gantry units can be compactly folded while being connected by the beam member.

より好ましいのは上架台の嵌合部についても、梁部材の上被嵌部が上方から嵌め込まれ、所定の嵌合位置で固定されるような構造とし、その上で上架台及び下架台の少なくとも一方に、梁部材を前記の嵌合位置から所定量、即ち例えば梁部材の軸部（下被嵌部）が下架台の丸穴から殆ど抜け出すくらい持ち上げた状態で、その軸部を回動自在に保持する保持部を設けることである（請求項３）。 More preferably, the fitting part of the upper frame is also structured such that the upper covering portion of the beam member is fitted from above and fixed at a predetermined fitting position, on which at least the upper frame and the lower frame are arranged. On the other hand, with the beam member lifted by a predetermined amount from the above-mentioned fitting position, that is, for example, with the shaft part (lower fitting part) of the beam member almost lifted out of the round hole of the undercarriage, the shaft part can be freely rotated. It is to provide the holding part to hold | maintain to (Claim 3).

こうすれば、一旦、取り付けた梁部材を持ち上げて、上下の被嵌部の嵌め合いを緩めた状態でも、その梁部材の軸部が回動自在に保持されるようになり、この軸部の周りに梁部材を容易に回動させることができる。よって、防振架台の折り畳みが容易に行える。 In this way, even if the attached beam member is lifted up and the fitting of the upper and lower fitting portions is loosened, the shaft portion of the beam member can be held rotatably. The beam member can be easily rotated around. Therefore, the anti-vibration mount can be easily folded.

また、好ましい構造として、前記梁部材を第１及び第２の２つの部材に分割しかつ該両部材同士を水平方向に折り畳み可能に連結してもよく（請求項４）、こうすれば防振架台をよりコンパクトに折り畳むことができる。その場合に、第１部材を相対的に剛性の高いものとし、これを梁部材の長手方向全体に、即ち防振架台の幅方向全体に亘って設けるのがよい（請求項５）。一方で第２部材は相対的に剛性の低いものでよく、その端部を前記第１部材の途中に回動可能に連結すればよい。 Further, as a preferred structure, the beam member may be divided into first and second members, and the two members may be connected so as to be foldable in the horizontal direction (Claim 4). The frame can be folded more compactly. In that case, it is preferable that the first member has relatively high rigidity and is provided over the entire longitudinal direction of the beam member, that is, over the entire width direction of the vibration isolator. On the other hand, the second member may have a relatively low rigidity, and its end may be connected to the middle of the first member so as to be rotatable.

また、別の好ましい構造として、前記梁部材のいずれか一方の端部において軸部を、当該梁部材の長手方向にスライド移動可能に設けた別体の軸部材としてもよい（請求項６）。こうすれば、上述の如く梁部材を軸部の周りに回動させて、防振架台を折り畳んだ後にその軸部に対して梁部材を長手方向にスライド移動させることにより、折り畳んだ防振架台の長さを短縮することができる。 As another preferred structure, the shaft portion may be a separate shaft member provided to be slidable in the longitudinal direction of the beam member at any one end of the beam member. In this way, the beam member is rotated around the shaft portion as described above, and the vibration isolation frame is folded, and then the beam member is slid in the longitudinal direction relative to the shaft portion, thereby folding the vibration isolation frame. Can be shortened.

その場合に梁部材の他方の端部においては、当該梁部材の側方に偏位して（即ち、側方に出っ張るようにして）軸部を設けることが好ましい（請求項７）。こうすれば、前記のように軸部の周りに回動させた梁部材を架台ユニットの上架台に沿わせて、防振架台をよりコンパクトに折り畳むことができる。 In this case, it is preferable that a shaft portion is provided at the other end portion of the beam member so as to be deviated laterally of the beam member (that is, projecting to the side). If it carries out like this, the beam member rotated around the axial part as mentioned above can be made to fold along the upper frame of a frame unit, and a vibration isolator frame can be folded more compactly.

さらにまた、前記梁部材の下被嵌部と前記下架台の嵌合部との間には弾性体を介在させることが好ましく、こうすれば機器の振動が上架台から梁部材の軸部を介して下架台に伝わることを抑制できる（請求項８）。 Furthermore, it is preferable that an elastic body is interposed between the lower fitting portion of the beam member and the fitting portion of the lower base, and in this way, vibration of the device is transmitted from the upper base via the shaft portion of the beam member. Can be prevented from being transmitted to the undercarriage (claim 8).

以上、説明したように本発明の防振架台は、一対の長尺状の架台ユニットを横並びに配設した簡易な構造を基本とし、組み立ての手間が掛からず重量やコストの削減も容易なものでありながら、それら架台ユニットの上架台ないし下架台同士を連結する梁部材を利用して上下の架台同士も連結する構造としたから、架台ユニットの捩れに対する剛性が高くなってその倒れ防止が図られる。よって、防振架台のぐらつきが少なくなって、設置作業も容易に行える。 As described above, the anti-vibration frame of the present invention basically has a simple structure in which a pair of long frame units are arranged side by side, which does not require assembling work and can easily reduce weight and cost. However, since the upper and lower frames are connected to each other using beam members that connect the upper and lower frames of the frame units, the rigidity of the frame units against torsion is increased, and the collapse is prevented. It is done. As a result, the shake of the anti-vibration stand is reduced, and the installation work can be easily performed.

また、前記梁部材を上架台の間に直線的に架け渡す構造とすれば、機器が直接、搭載される上架台の剛性を確保しやすい。その両端部に設けた丸棒状の軸部を下架台の丸穴（嵌合部）に嵌め込む構造とすれば、防振架台を折り畳むこともできる。 Further, if the beam member is linearly bridged between the upper bases, it is easy to ensure the rigidity of the upper base on which the device is directly mounted. If it is made the structure which fits the round rod-shaped shaft part provided in the both ends into the round hole (fitting part) of a lower frame, a vibration isolator frame can also be folded.

さらに、梁部材を２つの部材に分割して折り畳み可能に連結する構造としたり、或いは軸部の一方を梁部材の長手方向にスライド移動可能な別体の軸部材とすることによって、防振架台をよりコンパクトに折り畳めるようになる。 Further, the anti-vibration stand can be obtained by dividing the beam member into two members and connecting them in a foldable manner, or by using one of the shaft portions as a separate shaft member that can slide in the longitudinal direction of the beam member. Can be folded more compactly.

以下、本発明の実施形態を図面に基づいて詳細に説明する。尚、以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

（実施形態１）
図１には、本発明に係る防振架台を所謂エアコン防振台とした実施形態の一例を示し、同図(a)は平面図、(b)、(c)はそれぞれ正面図、側面図である。この防振架台は、図示しない空調装置の室外機を設置するためのものであり、図の例では長尺状の架台ユニット１（所謂レール式防振台である）を横並びに一対、並べて配設し、それらの両端に後述する梁部材７，７を架け渡して、連結している。 (Embodiment 1)
FIG. 1 shows an example of an embodiment in which the vibration isolator according to the present invention is a so-called air conditioner anti-vibration table. FIG. 1 (a) is a plan view, and FIG. 1 (b) and FIG. It is. This anti-vibration base is for installing an outdoor unit of an air conditioner (not shown). In the example shown in the figure, a long base unit 1 (which is a so-called rail-type anti-vibration base) is arranged side by side. The beam members 7 and 7 which will be described later are bridged and connected to both ends thereof.

この例では一対の架台ユニット１，１は同じものであり、各々断面矩形状の角パイプ（例えば構造用角形鋼管等）からなる長尺状の上架台２及び下架台３が、互いに上下方向に所定の間隔を空けて配置され、その間には上架台２及び下架台３の長手方向に離れて２つのアイソレータ４，４が介設されている。アイソレータ４は、上架台２及び下架台３の間の振動伝達を軽減する防振体であり、例えばコイルばねとゴムを一体成形したものや樹脂ケース内にコイルばねを内蔵したものが用いられる。 In this example, the pair of gantry units 1 and 1 are the same, and an elongated upper gantry 2 and lower gantry 3 each made of a square pipe having a rectangular cross section (for example, a square steel pipe for construction) are arranged vertically. Two isolators 4, 4 are interposed in the longitudinal direction of the upper pedestal 2 and the lower pedestal 3 between them. The isolator 4 is a vibration isolator that reduces vibration transmission between the upper pedestal 2 and the lower pedestal 3, and for example, a coil spring and a rubber that are integrally molded, or a resin case that incorporates a coil spring is used.

図示の架台ユニット１においては上架台２よりも下架台３が長く、その両端部がそれぞれ上架台２の端部よりも外方まで突出している。この突出する部位を覆うように、下架台３の両端部にはそれぞれ、鉄板をコ字状に折り曲げてなるベースプレート３１，３１，…が嵌着されている。一方、上架台２の両端部にはそれぞれ、鉄板を折り曲げてなるブラケット５が取り付けられていて、下方のベースプレート３１との間に、上架台２と下架台３との相対変位を規制するための耐震ストッパ機構６が構成されている。 In the illustrated gantry unit 1, the lower gantry 3 is longer than the upper gantry 2, and both end portions thereof protrude outward from the end portions of the upper gantry 2. Base plates 31, 31,... Formed by bending iron plates in a U-shape are fitted to both ends of the undercarriage 3 so as to cover the protruding portions. On the other hand, brackets 5 formed by bending iron plates are attached to both ends of the upper base 2, respectively, for restricting relative displacement between the upper base 2 and the lower base 3 between the lower base plate 31. An earthquake resistant stopper mechanism 6 is configured.

すなわち、図１(a)において右下に位置するものについて図２、３に拡大して示すと、ブラケット５は、その長辺が上下の架台２，３の長手方向に延びる概略矩形状の床部５０と、この床部５０の短辺の縁から上方に立ち上がる竪壁部５１と、床部５０の長辺の縁から上方に立ち上がる側壁部５２とを備え、それら竪壁部５１及び側壁部５２の側縁同士が接合されている。竪壁部５１の上縁は、角パイプである上架台２の下壁の端縁に沿って折れ曲がり、その下壁の上面に沿って延びる延出部が形成されていて、ここにおいて上架台２の下壁にネジ留め（符号２１がネジの頭部を示す）により締結されている。一方、側壁部５２にも上架台２の側壁の内面に沿って延びる延出部が形成され、この延出部が側壁にネジ留め（図４にネジ２２及びナット２３を示す）されている。 That is, when the one located at the lower right in FIG. 1A is enlarged and shown in FIGS. 2 and 3, the bracket 5 has a substantially rectangular floor whose long side extends in the longitudinal direction of the upper and lower frames 2 and 3. Part 50, a wall part 51 rising upward from the edge of the short side of the floor part 50, and a side wall part 52 rising upward from the edge of the long side of the floor part 50, the wall part 51 and the side wall part The side edges of 52 are joined. The upper edge of the ridge wall 51 is bent along the edge of the lower wall of the upper base 2 that is a square pipe, and an extending portion extending along the upper surface of the lower wall is formed. Here, the upper base 2 It is fastened to the lower wall by screwing (reference numeral 21 indicates the head of the screw). On the other hand, the side wall 52 is also formed with an extension extending along the inner surface of the side wall of the upper pedestal 2, and this extension is screwed to the side wall (a screw 22 and a nut 23 are shown in FIG. 4).

また、前記ブラケット５の床部５０の略中央には、図示は省略するがボルト貫通穴が開口していて、ここにストッパボルト６０の軸部が遊嵌状態で挿通されている。このストッパボルト６０は、角パイプである下架台３の上壁にナット６１（図３にのみ破線で示す）により締結されていて、そこから上方に延びる軸部がベースプレート３１とガイドプレート６２とを貫通している。ガイドプレート６２は、ナット６１の厚み分だけベースプレート３１から離れていて、このナット６１とナット６３との間に挟持されている。 In addition, although not shown, a bolt through hole is opened at the approximate center of the floor portion 50 of the bracket 5, and the shaft portion of the stopper bolt 60 is inserted in a loosely fitted state. The stopper bolt 60 is fastened by a nut 61 (shown only by a broken line in FIG. 3) to the upper wall of the lower base 3 that is a square pipe, and a shaft portion extending upward from the nut 61 connects the base plate 31 and the guide plate 62. It penetrates. The guide plate 62 is separated from the base plate 31 by the thickness of the nut 61 and is sandwiched between the nut 61 and the nut 63.

さらに、そうして上方に延びるストッパボルト６０の軸部は、前記のようにブラケット５の床部５０のボルト貫通穴に挿通されていて、その床部５０よりも上の部位にはリング状のゴムブッシュ６４と平座金６５とが外挿されるとともに、ナット６６が螺合されている。両図にはブラケット５の床部５０の上面にゴムブッシュ６４の接触している状態を示しているが、防振架台を使用するときにはナット６６の位置を調整して、両者の間に適当な大きさ（約２〜３ｍｍ程度）の隙間を形成する。このことで、地震等による上架台２及び下架台３の相対変位が制限される。 Furthermore, the shaft portion of the stopper bolt 60 that extends upward is inserted into the bolt through hole of the floor portion 50 of the bracket 5 as described above, and a ring-shaped portion is formed above the floor portion 50. The rubber bush 64 and the flat washer 65 are extrapolated and a nut 66 is screwed. Both figures show a state in which the rubber bush 64 is in contact with the upper surface of the floor 50 of the bracket 5, but when using a vibration isolator, the position of the nut 66 is adjusted so that an appropriate amount is provided between the two. A gap having a size (about 2 to 3 mm) is formed. This limits the relative displacement of the upper platform 2 and the lower platform 3 due to an earthquake or the like.

そして、この実施形態では、前記のように耐震ストッパ機構６を構成するためのブラケット５等を利用し、ここに梁部材７の端部を嵌め込んで固定するようにしている。すなわち、前記図２、３の他に図４にも示すように、梁部材７は鋼製の丸棒材からなり、その両端部にそれぞれ下向きに略直角に折れ曲がって延びる軸部７ａが設けられている。この軸部７ａは上架台２のブラケット５の床部５０を貫通し、その下方のガイドプレート６２、さらにはベースプレート３１や下架台３の上壁も貫通している。 In this embodiment, the bracket 5 for configuring the earthquake-resistant stopper mechanism 6 is used as described above, and the end portion of the beam member 7 is fitted and fixed thereto. That is, as shown in FIG. 4 in addition to FIGS. 2 and 3, the beam member 7 is made of a steel round bar, and is provided with shaft portions 7 a extending at substantially right angles downward at both ends thereof. ing. The shaft portion 7 a passes through the floor portion 50 of the bracket 5 of the upper base 2, and also penetrates the guide plate 62 below, and further the base plate 31 and the upper wall of the lower base 3.

すなわち、まず、梁部材７の端部において軸部７ａの付け根付近の部分７ｂが、ブラケット５の側壁部５２の上縁に開口するＵ字状の切り欠き５２ａに嵌め込まれている。換言すればその切り欠き５２ａが、梁部材７の上被嵌部７ｂ（前記した軸部７ａの付け根付近の部分）が嵌め込まれる上架台２の嵌合部であり、それがＵ字状、即ち下窄まりの形状になっていて、図示の嵌合位置においてしっかりと梁部材７と嵌合するようになる。 That is, first, a portion 7 b near the base of the shaft portion 7 a at the end of the beam member 7 is fitted into a U-shaped cutout 52 a that opens at the upper edge of the side wall portion 52 of the bracket 5. In other words, the notch 52a is a fitting portion of the upper base 2 into which the upper fitting portion 7b of the beam member 7 (the portion near the base of the shaft portion 7a) is fitted, and is a U-shape, that is, It is in the shape of a constriction, and comes to be securely fitted to the beam member 7 at the fitting position shown in the figure.

また、ブラケット５の床部５０には、梁部材７の軸部７ａが挿通される丸穴５０ａが開口しており、これを貫通して下方に延びる軸部７ａの下側の部分は、ガイドプレート６２に開口する丸穴６２ａに挿通され、さらにはベースプレート３１の丸穴３１ａ及びこれに連通する下架台３上壁の丸穴３ａ（以下、両者を合わせて下架台３上の丸穴３１ａ，３ａと略称する）に嵌入されている。 In addition, a round hole 50a through which the shaft portion 7a of the beam member 7 is inserted is opened in the floor portion 50 of the bracket 5, and a lower portion of the shaft portion 7a that extends downward through the guide hole is a guide. The round hole 31a of the base plate 31 and the round hole 3a of the upper wall of the lower base 3 that communicates with the round hole 31a (hereinafter referred to as the round holes 31a, 3a on the lower base 3 together (Abbreviated).

それらの丸穴５０ａ，６２ａ，３１ａ，３ａの開口径はいずれも軸部７ａの外径よりもやや大きめの適切な大きさに設定され、ルーズな嵌め合いになっている。特に、ブラケット５の床部５０の丸穴５０ａとガイドプレート６２の丸穴６２ａとは相対的に大きめで、軸部７ａの挿入ガイドとして機能する。一方、下架台３上の丸穴３１ａ，３ａは、やや小さめとされて、そこに嵌め込まれる軸部７ａの下端を保持しながら、振動の伝達は抑制するようになっている。つまり、この実施形態では前記下架台３上の丸穴３１ａ，３ａが、梁部材７の軸部７ａ（下被嵌部）が嵌め込まれる嵌合部である。 The opening diameters of these round holes 50a, 62a, 31a, 3a are all set to appropriate sizes that are slightly larger than the outer diameter of the shaft portion 7a, and are loosely fitted. In particular, the round hole 50a in the floor portion 50 of the bracket 5 and the round hole 62a in the guide plate 62 are relatively large and function as an insertion guide for the shaft portion 7a. On the other hand, the round holes 31a and 3a on the lower pedestal 3 are slightly smaller, and the transmission of vibration is suppressed while holding the lower end of the shaft portion 7a fitted therein. That is, in this embodiment, the round holes 31a, 3a on the lower mount 3 are fitting portions into which the shaft portion 7a (lower fitting portion) of the beam member 7 is fitted.

そうして、図示のように梁部材７の上下の被嵌部がそれぞれ上架台２及び下架台３の嵌合部に嵌め込まれた状態（嵌合位置）から、梁部材７を所定量、持ち上げれば、図４に仮想線で示すように軸部７ａの周りに回動させることができる。こうして持ち上げたときに軸部７ａの下端は下架台３上の丸穴３１ａ，３ａからは概ね抜け出すことになるが、軸部７ａの中間の部位は、ブラケット５の床部５０の丸穴５０ａとガイドプレート６２の丸穴６２ａとに挿入されたままで、ぐらつかずスムーズに回動させることができる。つまり、それらの丸穴５０ａ，６２ａは、梁部材７を嵌合位置から所定量、持ち上げた状態でその軸部７ａを回動自在に保持する機能も有している。 Then, the beam member 7 is lifted by a predetermined amount from the state (fitting position) in which the upper and lower fitting portions of the beam member 7 are fitted in the fitting portions of the upper base 2 and the lower base 3 as shown in the figure. Then, as shown by a virtual line in FIG. 4, it can be rotated around the shaft portion 7a. When lifted in this way, the lower end of the shaft portion 7a is almost removed from the round holes 31a, 3a on the undercarriage 3, but the intermediate portion of the shaft portion 7a is the round hole 50a of the floor portion 50 of the bracket 5 and the guide plate. It can be smoothly rotated without wobbling while being inserted into the 62 round holes 62a. That is, the round holes 50a and 62a also have a function of rotatably holding the shaft portion 7a in a state where the beam member 7 is lifted by a predetermined amount from the fitting position.

さらに、図２、４に示すように、ブラケット５の側壁部５２の上縁において切り欠き５２ａに対応する部位には、当該ブラケット５の内方に向かって略水平に延びる半円環状のガイド部５２ｂが設けられている。このガイド部５２ｂは、梁部材７の軸部７ａを挿入する際のガイドとなるものであるが、前記のように梁部材７を持ち上げた状態では、ガイドプレート６２の丸穴６２ａ等と同じく軸部７ａを保持する機能も有している。 Further, as shown in FIGS. 2 and 4, a semicircular guide portion extending substantially horizontally toward the inside of the bracket 5 is provided at a portion corresponding to the notch 52 a at the upper edge of the side wall portion 52 of the bracket 5. 52b is provided. The guide portion 52b serves as a guide when the shaft portion 7a of the beam member 7 is inserted. In the state where the beam member 7 is lifted as described above, the guide portion 52b has the same axis as the round hole 62a and the like of the guide plate 62. It also has a function of holding the portion 7a.

尚、図３、４における符号３１ｂ，３ｂは、前記した丸穴３１ａ，３ａと同じく互いに連通するようにベースプレート３１及び下架台３上壁に形成された丸穴であり、その下架台３を基礎に固定するアンカーボルトが挿通される。また、図１、２、５における符号２ａは、上架台２を室外機の底部に固定する締結ボルトの挿通される丸穴である。 3 and 4, reference numerals 31 b and 3 b are round holes formed in the upper wall of the base plate 31 and the lower base 3 so as to communicate with each other like the round holes 31 a and 3 a described above. Anchor bolts to be fixed to are inserted. Moreover, the code | symbol 2a in FIG.1, 2, 5 is a round hole through which the fastening bolt which fixes the upper mount 2 to the bottom part of an outdoor unit is penetrated.

したがって、上述した実施形態１に係る防振架台によると、例えば空調装置の室外機を設置するときには、長尺状の一対の架台ユニット１，１を横並びに配設して、その両端部にそれぞれ梁部材７の両端の軸部７ａを嵌め込む。こうすると軸部７ａは、上架台２の端部のブラケット５の床部５０やガイドプレート６２を貫通して、下架台３上の丸穴３１ａに嵌め込まれるとともに、その軸部７ａの付け根付近（上被嵌部７ｂ）がブラケット５の側壁部５２の切り欠き５２ａに嵌め込まれ、それぞれの嵌合位置にしっかりと固定される（図２〜４を参照）。 Therefore, according to the above-described vibration isolator according to the first embodiment, for example, when installing an outdoor unit of an air conditioner, a pair of elongated base units 1 and 1 are arranged side by side, respectively, at both ends thereof. The shaft portions 7a at both ends of the beam member 7 are fitted. In this way, the shaft portion 7a passes through the floor portion 50 and the guide plate 62 of the bracket 5 at the end of the upper base 2 and is fitted into the round hole 31a on the lower base 3, and the vicinity of the base of the shaft portion 7a (upper cover). The fitting portion 7b) is fitted into the notch 52a of the side wall portion 52 of the bracket 5, and is firmly fixed to each fitting position (see FIGS. 2 to 4).

この状態では、対をなす上架台２，２の両端部がぞれぞれ直線状の梁部材７，７によって連結されて矩形の枠状をなし、全体として高い剛性が確保されるのみならず、その梁部材７の軸部７ａによって上下の架台２，３同士が連結されることになり、架台ユニット１の捩れに対する剛性が高くなって、その倒れ防止が図られる。見方を変えれば、下架台３，３同士も梁部材７によって連結されて矩形枠状になっていると言うこともできる。 In this state, both ends of the pair of upper bases 2 and 2 are connected by linear beam members 7 and 7 to form a rectangular frame, and not only high rigidity is ensured as a whole. The upper and lower mounts 2 and 3 are connected to each other by the shaft portion 7a of the beam member 7, so that the rigidity of the mount unit 1 against torsion is increased, and the tilt is prevented. In other words, it can be said that the undercarriages 3 and 3 are also connected by the beam member 7 to have a rectangular frame shape.

さらに、そうして防振架台を組み立てるときには、前記のように横並びに配置した架台ユニット１，１の両端部に、それぞれ梁部材７の両端の軸部７ａを上方から押し込めばよく、組み立ての手間が掛からないし、組み立てる前の架台ユニット１と梁部材７とはコンパクトに梱包できるので、設置場所への運搬もしやすい。また、予め工場で防振架台を組み立てた後に折り畳んで運搬し、設置場所で展開することもできる。 Further, when assembling the vibration isolator, the shaft portions 7a at both ends of the beam member 7 may be pushed into the both ends of the frame units 1 and 1 arranged side by side as described above. Since the gantry unit 1 and the beam member 7 before assembling can be packed compactly, it is easy to carry to the installation location. Moreover, after assembling the vibration isolator in advance at the factory, it can be folded and transported and deployed at the installation location.

そうして折り畳んだり展開したりするときには、前記のように架台ユニット１，１の間に架け渡した梁部材７を少しだけ持ち上げて、上下の架台２，３の嵌合部との嵌め合いを緩めておき、この状態で梁部材７が軸部７ａの周りに回動するように架台ユニット１，１同士を近づける。こうすると、図５に示すように架台ユニット１，１を梁部材７，７によって連結したまま、防振架台を平行四辺形状に変形させてコンパクトに折り畳むことができる。 When folding and unfolding in this way, the beam member 7 spanned between the gantry units 1 and 1 as described above is slightly lifted to fit the fitting parts of the upper and lower gantry 2 and 3. In this state, the gantry units 1 and 1 are brought closer to each other so that the beam member 7 rotates around the shaft portion 7a. If it carries out like this, as shown in FIG. 5, with the gantry units 1 and 1 being connected by the beam members 7 and 7, the anti-vibration gantry can be transformed into a parallelogram shape and folded compactly.

しかも、そうして梁部材７を少し持ち上げた状態でその両端の軸部７ａが、ブラケット５の側壁部５２のガイド部５２ｂや同床部５０の丸穴５０ａ、さらにはガイドプレート６２の丸穴６２ａによって回動自在に保持されているから、梁部材７の回動がスムーズなものになり、前記防振架台の折り畳みや展開が容易に行える。 Moreover, with the beam member 7 slightly lifted, the shaft portions 7a at both ends thereof are the guide holes 52b of the side wall 52 of the bracket 5, the round holes 50a of the floor 50, and the round holes of the guide plate 62. Since it is rotatably held by 62a, the beam member 7 can be smoothly rotated, and the vibration isolator can be easily folded and unfolded.

ところで、この実施形態では梁部材７を鋼製の丸棒材によって構成しているが、これは鋼製或いはアルミ合金の丸パイプ等であってもよいし、後述する実施形態２のようにＬ字アングルを利用することもできる。 By the way, in this embodiment, the beam member 7 is made of a steel round bar material, but this may be a steel or aluminum alloy round pipe, etc. A character angle can also be used.

また、前記したように梁部材７の端部をブラケット５の側壁部５２の切り欠き５２ａに嵌め込み、かつその軸部７ａを下架台３上の丸穴３１ａ，３ａに嵌め込む構造は、一例に過ぎない。例えば、軸部７ａの中間に下窄まりのテーパ状部を形成し、これをブラケット５の床部５０の丸穴５０ａやガイドプレート６２の丸穴６２ａに嵌め込む構造としてもよい。 Further, as described above, the structure in which the end portion of the beam member 7 is fitted into the notch 52a of the side wall portion 52 of the bracket 5 and the shaft portion 7a is fitted into the round holes 31a and 3a on the lower base 3 is merely an example. . For example, a tapered tapered portion may be formed in the middle of the shaft portion 7a, and this may be fitted into the round hole 50a of the floor portion 50 of the bracket 5 or the round hole 62a of the guide plate 62.

同様に下架台３上の丸穴３１ａ，３ａに嵌め込む軸部７ａの下端にも下窄まりのテーパ状部を形成してもよいし、この下架台３上の丸穴３１ａには、後述する実施形態２のようにゴムブッシュ等を嵌め込んでもよい。 Similarly, a tapered portion may be formed at the lower end of the shaft portion 7a that fits in the round holes 31a, 3a on the lower frame 3, and a round hole 31a on the lower frame 3 is formed in a second embodiment to be described later. A rubber bush or the like may be fitted as shown in FIG.

（実施形態２）
次に、図６〜９には本発明の実施形態２に係る防振架台を示す。この実施形態２は、主に梁部材８の構造が実施形態１と異なっていて、その両端が取り付けられる上架台２及び下架台３の嵌合部の構造にも異なる部分があるが、それ以外の構造は実施形態１のものと同じなので、以下、概ね同じ構造の部材には同じ符号を付し、異なる部分についてのみ説明する。 (Embodiment 2)
Next, FIGS. 6 to 9 show a vibration isolator according to Embodiment 2 of the present invention. In this second embodiment, the structure of the beam member 8 is mainly different from that of the first embodiment, and there are also different parts in the structure of the fitting parts of the upper base 2 and the lower base 3 to which both ends are attached. Since the structure is the same as that of the first embodiment, members having substantially the same structure are denoted by the same reference numerals and only different portions will be described below.

この実施形態の梁部材８は、図の例ではＬ字アングル８０（第１部材）と丸棒部材８１（第２部材）とを組合せて、水平方向に折り畳み可能に連結したものであり、この梁部材８の両端からそれぞれ下方に延びる丸棒状の軸部８１ａ，８２ａが上架台２及び下架台３に連繋されている。すなわち、まず、Ｌ字アングル８０は、図６のように展開した状態では実施形態１の梁部材７と同様に、対をなす架台ユニット１，１の上架台２，２の端部間に直線的に架け渡されている。 In the illustrated example, the beam member 8 of this embodiment is an L-shaped angle 80 (first member) and a round bar member 81 (second member), which are connected so as to be foldable in the horizontal direction. Round bar-shaped shaft portions 81 a and 82 a extending downward from both ends of the beam member 8 are connected to the upper base 2 and the lower base 3. That is, first, the L-shaped angle 80 is a straight line between the ends of the upper bases 2 and 2 of the pair of base units 1 and 1 in the state of being deployed as shown in FIG. It is overlaid.

そして、その一端（同図(a)の左下及び右上に示す端）には、図７や図８(a)にも示すように、板材を折り曲げてなる矩形ボックス状の部材８３を介して、Ｌ字状の丸棒からなる軸部材８２が取り付けられている。この軸部材８２のうち水平方向に延びる部分は、図７，８(a)に破線で示すようにボックス状部材８３内に収容されて、溶接若しくはネジ留めにより固定されている。一方、軸部材８２の垂直部分、即ち上下方向に延びる軸部８２ａは、ブラケット５の側壁部５２に設けられた突片部５３を貫通して下方に延び、さらにガイドプレート６２及びベースプレート３１を貫通している。 And, as shown in FIG. 7 and FIG. 8 (a), at one end thereof (ends shown in the lower left and upper right of FIG. 7A), through a rectangular box-shaped member 83 formed by bending a plate material, A shaft member 82 made of an L-shaped round bar is attached. A portion extending in the horizontal direction of the shaft member 82 is accommodated in a box-shaped member 83 and fixed by welding or screwing as shown by broken lines in FIGS. On the other hand, the vertical portion of the shaft member 82, that is, the shaft portion 82 a extending in the up-down direction, extends downward through the protruding piece portion 53 provided on the side wall portion 52 of the bracket 5, and further penetrates the guide plate 62 and the base plate 31. is doing.

ここで、この実施形態のブラケット５は、実施形態１のものと同様に床部５０、竪壁部５１及び側壁部５２を備えているが、細部の構造は異なっている。すなわち、竪壁部５１の上縁から折れ曲がって延びる延出部は上架台２の下壁に下方から重ね合わされ、その両側縁からそれぞれ上方に立ち上がる延出側壁５４，５５と併せて、上方に開口するコ字状に形成されている。尚、図の例では延出側壁５５が側壁部５２に連続している。そして、それら両延出側壁５４，５５が上架台２の側壁に外側から重ね合わされて、横方向に貫通するネジ２４とナット２５とにより締結されている。 Here, although the bracket 5 of this embodiment is provided with the floor part 50, the eaves wall part 51, and the side wall part 52 similarly to the thing of Embodiment 1, the structure of details differs. In other words, the extended portion that is bent from the upper edge of the flange wall portion 51 is overlapped with the lower wall of the upper base 2 from below, and is opened upward together with the extended side walls 54 and 55 that rise upward from both side edges thereof. It is formed in a U shape. In the illustrated example, the extended side wall 55 is continuous with the side wall portion 52. These extended side walls 54 and 55 are superimposed on the side wall of the upper base 2 from the outside, and are fastened by screws 24 and nuts 25 penetrating in the lateral direction.

また、この実施形態のブラケット５において側壁部５２には、実施形態１のようなＵ字状の切り欠き５２ａや環状のガイド部５２ｂが設けられておらず、その代わりに側壁部５２の側縁（図８(a)の手前の縁）に開口する切り欠き５２ｃと、側壁部５２の上縁から外方に延びるガイド部５６とが設けられている。このガイド部５６は、図８(a)の手前側に開口する切り欠きを有し、以下に述べる突片部５３の丸穴５３ａ（同図(b)を参照）等に軸部材８２の軸部８２ａを嵌め入れるときのガイドとして機能する。 Further, in the bracket 5 of this embodiment, the side wall portion 52 is not provided with the U-shaped notch 52a or the annular guide portion 52b as in the first embodiment, and instead, the side edge of the side wall portion 52 is provided. A notch 52c that opens to (the front edge in FIG. 8A) and a guide portion 56 that extends outward from the upper edge of the side wall portion 52 are provided. The guide portion 56 has a notch that opens toward the front side of FIG. 8A, and the shaft member 82 is inserted into a round hole 53a (see FIG. 8B) of the protruding piece portion 53 described below. It functions as a guide for fitting the portion 82a.

すなわち、前記の突片部５３には、実施形態１における床部５０の丸穴５０ａと同じく軸部材８２の軸部８２ａが貫通する丸穴５３ａが形成され、この丸穴を通過して下方に延びる軸部８２ａの下側の部分が、ガイドプレート６２の丸穴６２ａとベースプレート３１の丸穴３１ａとに嵌め込まれる。図の例では突片部５３がブラケット５の側壁部５２から上架台２の幅方向外方（図の右方）に突出し、これに対応してガイドプレート６２及びベースプレート３１の一部分が下架台３の外方に延出していて、この延出部分に丸穴６２ａ，３１ａが形成されている。 That is, the projecting piece 53 is formed with a round hole 53a through which the shaft portion 82a of the shaft member 82 penetrates in the same manner as the round hole 50a of the floor portion 50 in the first embodiment. The lower part of the extending shaft portion 82 a is fitted into the round hole 62 a of the guide plate 62 and the round hole 31 a of the base plate 31. In the example shown in the figure, the projecting piece 53 protrudes from the side wall 52 of the bracket 5 to the outside in the width direction of the upper base 2 (to the right in the figure), and a part of the guide plate 62 and the base plate 31 correspondingly corresponds to this. The round holes 62a and 31a are formed in the extended portion.

また、図の例では、それらの丸穴３１ａ，６２ａに共通のゴムブッシュ３２が嵌め込まれており、このゴムブッシュ３２を間に介在させて軸部８２ａの下側の部分が嵌め込まれている。つまり、図８(a)に示す梁部材８の一端部においては、ベースプレート３１及びガイドプレート６２の丸穴３１ａ，６２ａが、当該梁部材８（Ｌ字アングル８０）の一端の軸部８２ａが嵌め込まれる下架台３の嵌合部であり、この嵌合部と下被嵌部である軸部８２ａとの間にゴムブッシュ３２が介在されることで、振動の伝達が抑制されるようになっている。 Further, in the example shown in the drawing, a common rubber bush 32 is fitted into the round holes 31a and 62a, and the lower portion of the shaft portion 82a is fitted with the rubber bush 32 interposed therebetween. That is, in one end portion of the beam member 8 shown in FIG. 8A, the round holes 31a and 62a of the base plate 31 and the guide plate 62 are fitted into the shaft portion 82a at one end of the beam member 8 (L-shaped angle 80). Since the rubber bush 32 is interposed between the fitting portion and the shaft portion 82a which is the lower fitting portion, the transmission of vibration is suppressed. Yes.

さらに、前記ブラケット５の側壁部５２の切り欠き５２ｃには、ボックス状部材８３の端部に取り付けられた締付ボルト８４の軸部が嵌め込まれて、ナット８５を締め付けることにより梁部材８（Ｌ字アングル８０）の一端部が締結されるようになっている。また、そうして締め付けたナット８５を緩めてからＬ字アングル８０を、図８(a)において奥に向かうよう軸部８２ａの周りに回動させと、締付ボルト８４の軸部は切り欠き５２ｃから抜け出すことになる。つまり、この締付ボルト８４の軸部が梁部材８の上被嵌部であり、これが嵌め込まれる切り欠き５２ｃが、上架台２の嵌合部である。 Furthermore, the shaft portion of the fastening bolt 84 attached to the end portion of the box-shaped member 83 is fitted into the notch 52c of the side wall portion 52 of the bracket 5, and the beam member 8 (L One end of the character angle 80) is fastened. Further, after loosening the nut 85 thus tightened, the L-shaped angle 80 is rotated around the shaft portion 82a toward the back in FIG. 8A, so that the shaft portion of the tightening bolt 84 is notched. It will escape from 52c. That is, the shaft portion of the fastening bolt 84 is the upper fitting portion of the beam member 8, and the notch 52 c into which the shaft member is fitted is the fitting portion of the upper base 2.

前記のように構成されたＬ字アングル８０に組み合わされる丸棒部材８１は、図７に分解して示すように、Ｌ字アングル８０に沿って略水平に延びる部分の先端（同図の左端）が、当該Ｌ字アングル８０の途中に回動可能にピン留めされている。すなわちＬ字アングル８０の長手方向の中間部においてその上壁部から下方に垂下するようにボルト８６が配設されていて、その軸部に、丸棒部材８１の先端に設けられた環状部８１ｂが外挿され、ナット８７により抜け止めがなされている。 The round bar member 81 combined with the L-shaped angle 80 configured as described above has a distal end (left end in FIG. 7) that extends substantially horizontally along the L-shaped angle 80 as shown in an exploded view in FIG. However, it is pinned in the middle of the L-shaped angle 80 so as to be rotatable. That is, a bolt 86 is disposed so as to hang downward from the upper wall portion in the middle portion in the longitudinal direction of the L-shaped angle 80, and an annular portion 81 b provided at the tip of the round bar member 81 on the shaft portion. Is externally inserted, and the nut 87 prevents it from coming off.

また、丸棒部材８１の基端（図の右端）には下向きに略直角に折れ曲がって延びる軸部８１ａが設けられていて、この軸部８１ａが前記した軸部材８２の軸部８２ａと同様に、上架台２のブラケット５の突片部５３と、ガイドプレート６２及びベースプレート３１とを貫通するようになっている。すなわち、図８(b)に示すように梁部材８の他端部におけるブラケット５は、前記した一端部のものと略同様に構成され、その側壁部５２に設けられた突片部５３の丸穴５３ａに丸棒部材８１の軸部８１ａが挿通されている。 Further, a shaft portion 81a is provided at the base end (right end in the drawing) of the round bar member 81 so as to be bent downward at a substantially right angle, and this shaft portion 81a is similar to the shaft portion 82a of the shaft member 82 described above. The protruding piece 53 of the bracket 5 of the upper base 2, the guide plate 62 and the base plate 31 are penetrated. That is, as shown in FIG. 8B, the bracket 5 at the other end of the beam member 8 is configured in substantially the same manner as that at the one end described above, and the round of the protruding piece 53 provided on the side wall 52 thereof. The shaft portion 81a of the round bar member 81 is inserted through the hole 53a.

一方、この他端のブラケット５においては側壁部５２の側方に開口する切り欠き５２ｃは設けられておらず、その代わりに実施形態１のもの（切り欠き５２ａ）と同様に上縁に開口する切り欠き５２ｄが設けられている。この切り欠き５２ｄには、Ｌ字アングル８０の他端部に配設された締付ボルト８８の軸部が上方から嵌め込まれ、ナット８９により締め付けられる。換言すれば、この締付ボルト８８の軸部が梁部材８の他端部における上被嵌部であり、これが嵌め込まれる前記切り欠き５２ｄが上架台２の嵌合部である。 On the other hand, the bracket 5 at the other end is not provided with a notch 52c that opens to the side of the side wall 52, and instead opens at the upper edge as in the first embodiment (notch 52a). A notch 52d is provided. A shaft portion of a fastening bolt 88 disposed at the other end portion of the L-shaped angle 80 is fitted into the notch 52 d from above, and is tightened by a nut 89. In other words, the shaft portion of the fastening bolt 88 is the upper fitting portion at the other end portion of the beam member 8, and the notch 52 d into which the shaft portion is fitted is the fitting portion of the upper base 2.

そして、以上のように構成された実施形態２の防振架台は、図６のように展開された状態では、対をなす架台ユニット１，１の間に高剛性のＬ字アングル８０が架け渡されて、その両端部がそれぞれ上架台２の端部のブラケット５に締付ボルト８４，８８により締結され、両端の軸部８１ａ，８２ａによる嵌め合いとも併せて強固に固定される。よって、上架台２，２と梁部材８，８とがしっかりとした枠状をなし、全体として高い剛性を確保することができる。 The anti-vibration gantry of the second embodiment configured as described above has a high-rigidity L-shaped angle 80 spanned between the gantry units 1 and 1 that form a pair when deployed as shown in FIG. Then, both end portions thereof are fastened to the bracket 5 at the end portion of the upper base 2 by fastening bolts 84 and 88, and are firmly fixed together with the fitting by the shaft portions 81a and 82a at both ends. Therefore, the upper bases 2 and 2 and the beam members 8 and 8 form a firm frame shape, and high rigidity can be ensured as a whole.

一方で相対的に剛性の低い丸棒部材８１は、防振架台を折り畳むときにＬ字アングル８０を支えるものである。すなわち、前記のように展開されている防振架台を折り畳むときには、まず、梁部材８の両端部においてそれぞれＬ字アングル８０の端部のナット８５，８９を緩める。それからＬ字アングル８０の他端部（図８(b)に示す）を上方に持ち上げて、締付ボルト８８の軸部を切り欠き５２ｄから取り出した後に、同図において奥に向かうよう軸部８１ａの周りに少しだけ回動させる。 On the other hand, the relatively low-rigidity round bar member 81 supports the L-shaped angle 80 when the vibration isolator is folded. That is, when the anti-vibration mount that has been deployed as described above is folded, first, the nuts 85 and 89 at the ends of the L-shaped angle 80 are loosened at both ends of the beam member 8. Then, the other end portion of the L-shaped angle 80 (shown in FIG. 8B) is lifted upward, and the shaft portion of the fastening bolt 88 is taken out from the notch 52d, and then the shaft portion 81a is directed to the back in the drawing. Rotate a little around.

そうしておいて、図９(a)に示すように架台ユニット１，１同士を近づけると、Ｌ字アングル８０がその一端部の軸部８２ａの周りに回動するとともに、丸棒部材８１がその軸部８１ａの周りに回動して、両者を併せた梁部材８全体がパンタグラフのように折り畳まれる。こうして、架台ユニット１，１を梁部材８，８によって連結したまま、同図(b)に示すように防振架台をコンパクトに折り畳むことができる。 Then, as shown in FIG. 9 (a), when the gantry units 1 and 1 are brought close to each other, the L-shaped angle 80 rotates around the shaft portion 82a at one end thereof, and the round bar member 81 By rotating around the shaft portion 81a, the entire beam member 8 including both is folded like a pantograph. In this way, the anti-vibration frame can be folded compactly as shown in FIG. 5B while the frame units 1 and 1 are connected by the beam members 8 and 8.

尚、この実施形態２においては前記したようにＬ字アングル８０の両端にそれぞれ締付ボルト８４，８８を設けて、ブラケット５の側壁部５２に締結するようにしているが、これはしなくてもよい。また、梁部材８をＬ字アングル８０と丸棒部材８１とによって構成する必要もなく、両者をいずれもＬ字アングルによって構成することも、また、棒部材やパイプによって構成することも可能である。 In the second embodiment, as described above, the fastening bolts 84 and 88 are provided at both ends of the L-shaped angle 80 so as to be fastened to the side wall 52 of the bracket 5, but this is not necessary. Also good. Further, it is not necessary to configure the beam member 8 by the L-shaped angle 80 and the round bar member 81, both of which can be configured by the L-shaped angle, or can be configured by a bar member or a pipe. .

（実施形態３）
次に図１０〜１３には、本発明の実施形態３に係る防振架台を示す。この実施形態３の防振架台も梁部材９とその両端が嵌め込まれる上架台２や下架台３の嵌合部の構造に、実施形態１、２とは異なる部分があるが、それ以外の構造は実施形態１、２のものと同じなので、以下、概ね同じ構造の部材には同じ符号を付し、異なる部分のみ説明する。 (Embodiment 3)
Next, FIGS. 10 to 13 show a vibration isolator according to Embodiment 3 of the present invention. The anti-vibration frame of the third embodiment also has a portion different from the first and second embodiments in the structure of the fitting portion of the upper frame 2 and the lower frame 3 into which the beam member 9 and both ends thereof are fitted. Since this is the same as that of the first and second embodiments, members having substantially the same structure are denoted by the same reference numerals and only different portions will be described below.

この実施形態３の特徴は、図１１に示すように防振架台を折り畳むと梁部材９が上下の架台２，３に沿って概ね平行に延びるようになり（同図(a)）、その後、梁部材９を角パイプである上架台２の内部に収容することで（同図(b)）、全長が短縮されることにある。そのために、例えば同図において下側の架台ユニット１（上架台２）の一端（図の左端）においては、拡大して図１２に示すように梁部材９の一端の軸部が別体の軸部材９１により構成されて、丸棒材からなる梁部材９の本体部９０に対してその長手方向にスライド移動可能に取り付けられている。一方、架台ユニット１の他端（図の右端）においては、拡大して図１３にも示すように、梁部材９の本体部９０の端部にはその側方に偏位するようにクランク部材９２を介して軸部材９３が取り付けられている。 The feature of the third embodiment is that when the vibration isolator is folded as shown in FIG. 11, the beam member 9 extends substantially in parallel along the upper and lower bases 2 and 3 (FIG. 11A). By accommodating the beam member 9 in the upper base 2 that is a square pipe (FIG. 5B), the total length is shortened. Therefore, for example, at one end (the left end in the figure) of the lower gantry unit 1 (upper gantry 2) in the figure, the shaft portion at one end of the beam member 9 is a separate shaft as shown in FIG. It is comprised by the member 91, and is attached with respect to the main-body part 90 of the beam member 9 which consists of a round bar material so that a slide movement is possible in the longitudinal direction. On the other hand, at the other end (right end in the figure) of the gantry unit 1, as shown in FIG. 13 in an enlarged manner, the end of the main body 90 of the beam member 9 is displaced to the side thereof. A shaft member 93 is attached via 92.

詳しくは、まず、前記のように上架台２の両端にそれぞれ配設されているブラケット５は、実施形態１、２のものと同じく床部５０、竪壁部５１及び側壁部５２を有し、その床部５０に開口する丸穴５０ａには梁部材９の軸部である軸部材９１，９３が挿通されている。また、それら軸部材９１，９３の下側の部分は、ガイドプレート６２の丸穴６２ａと下架台３上の丸穴３１ａ（下架台３の嵌合部）とに嵌入されている。 Specifically, first, the brackets 5 respectively disposed at both ends of the upper base 2 as described above have the floor portion 50, the wall portion 51, and the side wall portion 52 as in the first and second embodiments. Shaft members 91 and 93 that are shaft portions of the beam member 9 are inserted into the round holes 50 a that open to the floor portion 50. The lower portions of the shaft members 91 and 93 are fitted into the round holes 62a of the guide plate 62 and the round holes 31a (the fitting portion of the lower base 3) on the lower base 3.

同様にブラケット５の側壁部５２には、その上縁に開口するＵ字状の切り欠き５２ａが形成されて、梁部材９の両端部が嵌め込まれるようになっている。すなわち、上架台２の一端部のブラケット５においては、図１２(a)に示すように側壁部５２の切り欠き５２ａに、梁部材本体部９０の端部付近（上被嵌部９０ａ）が上方から嵌め込まれる。この部位よりも先端側で梁部材本体部９０は、軸部材９１の上端に形成された平板部の丸穴９１ａを貫通しており、その先端には抜け止めのための矩形片９０ｂが溶接されている。 Similarly, a U-shaped cutout 52 a that opens at the upper edge of the side wall 52 of the bracket 5 is formed so that both ends of the beam member 9 are fitted. That is, in the bracket 5 at one end portion of the upper base 2, as shown in FIG. 12 (a), the vicinity of the end portion of the beam member main body portion 90 (upper fitting portion 90a) is located above the notch 52a of the side wall portion 52. It is inserted from. The beam member main body 90 passes through the round hole 91a of the flat plate portion formed at the upper end of the shaft member 91 on the tip side from this portion, and a rectangular piece 90b for preventing the removal is welded to the tip. ing.

一方、上架台２の他端部おいては、図１３(a)に示すようにブラケット５の側壁部５２の切り欠き５２ａに、クランク部材９２の折曲部付近（上被嵌部９２ａ）が上方から嵌め込まれる。図示のようにクランク部材９２は下方に開口する断面コ字状のものであり、その基端部には軸部材９３の上端が下方から嵌め込まれて溶接されている一方、先端側には梁部材本体部９０の端部が挿入されて溶接ないしネジ留めされている。 On the other hand, at the other end of the upper base 2, as shown in FIG. 13A, the notch 52 a of the side wall 52 of the bracket 5 has a vicinity of the bent portion (upper fitting portion 92 a) of the crank member 92. It is fitted from above. As shown in the figure, the crank member 92 has a U-shaped section that opens downward, and the upper end of the shaft member 93 is fitted and welded to the base end portion from below, while the beam member is on the distal end side. The end of the main body 90 is inserted and welded or screwed.

そして、前記図１１(a)に示すように防振架台を折り畳むときには、図１３(a)に仮想線の矢印で示すように、梁部材９を少し持ち上げてから軸部材９３の周りに約９０°回動させることになるが、こうすると同図(b)に示すように梁部材９は、クランク部材９２を上架台２上に乗り上げた状態で当該上架台２の側方を概ね平行に延びるようになる。 When the vibration isolator is folded as shown in FIG. 11 (a), the beam member 9 is lifted up a little, as shown by an imaginary line arrow in FIG. In this case, the beam member 9 extends in substantially parallel to the side of the upper base 2 with the crank member 92 mounted on the upper base 2 as shown in FIG. It becomes like this.

このとき、図１２に示した上架台２の一端部においても梁部材９の本体部９０が軸部材９１の周りに約９０°回動して、同図(b)や前記図１１(a)にも示すように上架台２と直列に並んで概ね一直線上に位置するようになる。そこで、この状態から軸部材９１の丸穴９１ａをガイドにして、同図に仮想線の矢印で示すように梁部材本体部９０をその軸心方向に移動させ、角パイプである上架台２の内部に挿入することができる（図１１(b)）。 At this time, the main body 90 of the beam member 9 also rotates about 90 ° around the shaft member 91 at one end of the upper base 2 shown in FIG. As shown also in FIG. 2, it is located in a straight line in line with the upper base 2 in series. Therefore, from this state, the circular hole 91a of the shaft member 91 is used as a guide, and the beam member main body 90 is moved in the axial direction as shown by an imaginary line arrow in FIG. It can be inserted inside (FIG. 11 (b)).

したがって、この実施形態３に係る防振架台によると、図１０のように展開された状態では、実施形態１のものと同様に梁部材９の両端の上被嵌部９０ａ，９２ａが上架台２のブラケット５に嵌め合わされるとともに、その付近から下方に延びる軸部材９１，９３（下被嵌部）がブラケット５の床部５０とガイドプレート６２とを貫通して、下架台３上の丸穴３１ａに嵌め込まれることで、上架台２，２と梁部材９，９とがしっかりとした枠状をなすとともに、軸部材９１，９３によって上下の架台２，３同士が連結されて、架台ユニット１の捩れに対する剛性が高くなり、その倒れ防止が図られる。 Therefore, according to the anti-vibration gantry according to the third embodiment, the upper fitted portions 90a and 92a at both ends of the beam member 9 are formed on the upper gantry 2 in the state of being developed as shown in FIG. The shaft members 91 and 93 (lower covering portions) extending downward from the vicinity of the bracket 5 pass through the floor portion 50 of the bracket 5 and the guide plate 62 and are inserted into the round holes 31a on the lower platform 3. By being fitted, the upper bases 2 and 2 and the beam members 9 and 9 form a solid frame shape, and the upper and lower bases 2 and 3 are connected to each other by the shaft members 91 and 93, so that the base unit 1 is twisted. The rigidity with respect to is increased, and the fall is prevented.

また、図１１(a)に示すように防振架台を折り畳むときには、まず、梁部材９を持ち上げてその両端部の軸部材９１，９３の上下の架台２，３との嵌め合いを緩めた後に、梁部材９，９がそれぞれ軸部材９１，９３の周りに回動するように架台ユニット１，１同士をその幅方向に近づけて、同図に実線で示すように一対の架台ユニット１，１を梁部材９，９によって連結したまま直線状に折り畳む。 When the vibration isolator is folded as shown in FIG. 11 (a), the beam member 9 is first lifted to loosen the fitting between the upper and lower bases 2 and 3 of the shaft members 91 and 93 at both ends thereof. The gantry units 1 and 1 are brought closer to each other in the width direction so that the beam members 9 and 9 rotate around the shaft members 91 and 93, respectively, and a pair of gantry units 1 and 1 are shown as indicated by solid lines in FIG. Are folded in a straight line while being connected by the beam members 9 and 9.

このとき、図示のように梁部材９，９は、その一端部が軸部材９１を介して連結されている架台ユニット１の上架台２とは、概ね一直線上に直列に位置し、また、他端部がクランク部材９２及び軸部材９３を介して連結されている架台ユニット１の上架台２とは、略平行に並ぶようになる。よって、この状態から架台ユニット１，１同士を今度は長手方向に移動させて、その上架台２の内部に軸部材９を挿入すれば、同図(b）のように防振架台の全長が短縮される。 At this time, as shown in the figure, the beam members 9 and 9 are positioned in series on a substantially straight line with the upper base 2 of the base unit 1 whose one end is connected via the shaft member 91. The upper part 2 of the gantry unit 1 whose ends are connected via the crank member 92 and the shaft member 93 are arranged substantially in parallel. Therefore, if the gantry units 1 and 1 are moved in the longitudinal direction from this state and the shaft member 9 is inserted into the upper gantry 2 as shown in FIG. Shortened.

尚、この実施形態３においては梁部材９の本体部９０の他端部に別体のクランク部材９２と軸部材９３とを取り付けているが、梁部材９の本体部９０を折り曲げてクランク部や軸部を設けることも可能である。また、そうしてクランク部を設けなくても梁部材９の一部を上架台２の内部に収容することは可能である。 In the third embodiment, a separate crank member 92 and shaft member 93 are attached to the other end of the main body 90 of the beam member 9, but the main body 90 of the beam member 9 is bent to It is also possible to provide a shaft portion. In addition, a part of the beam member 9 can be accommodated in the upper base 2 without providing a crank portion.

さらに、本発明に係る防振架台の構造は、前記した実施形態１〜３のものに限定されず、それ以外の種々の構成をも包含する。例えば各実施形態ではいずれも、梁部材７〜９を架台ユニット１，１の上架台２，２の間に架け渡しているが、これに限らず、下架台３，３の間に架け渡し、上方に延びる軸部等を上架台２に嵌め込むようにしてもよい。或いは梁部材を上下の架台２，３の中間の高さに架け渡して、その両端から上下にそれぞれ延びる軸部を上架台２、下架台３に嵌め込むようにしてもよい。 Furthermore, the structure of the vibration isolator according to the present invention is not limited to that of the first to third embodiments, and includes various other configurations. For example, in each embodiment, the beam members 7 to 9 are bridged between the upper racks 2 and 2 of the gantry unit 1, 1. A shaft portion or the like extending upward may be fitted into the upper base 2. Alternatively, the beam member may be bridged between the upper and lower frames 2 and 3, and the shaft portions extending vertically from both ends may be fitted into the upper frame 2 and the lower frame 3.

また、上架台２や下架台３は角パイプによって構成する必要はないし、梁部材７〜９も含めて前記した実施形態１〜３に記載されている部材の形状や材料等は全て単なる例示に過ぎないことは言うまでもない。 Further, the upper base 2 and the lower base 3 do not need to be configured by square pipes, and all the shapes and materials of the members described in the first to third embodiments including the beam members 7 to 9 are merely examples. It goes without saying that it is not too much.

さらにまた、本発明に係る防振架台は、上述の実施形態のようなエアコン防振台に限定されず、例えば液体ポンプユニットやボイラー等、種々の設備機器の防振架台としても適用可能である。 Furthermore, the vibration isolator according to the present invention is not limited to the air conditioner anti-vibration base as in the above-described embodiment, and can be applied as a vibration isolator for various equipment such as a liquid pump unit and a boiler. .

以上、説明したように本発明は、長尺状の架台ユニットを横並びに設けた簡易な構造で組み立ての手間が掛からず、重量やコストを削減できる上に設置作業も容易になるから、汎用の防振架台として有用なものである。 As described above, the present invention has a simple structure in which long gantry units are provided side by side, which does not require assembling work, reduces weight and cost, and facilitates installation work. It is useful as a vibration isolator.
