本発明は、エンジン駆動の圧縮機、発電機、溶接機又はポンプ等のエンジン駆動作業機に使用される雨樋に関する。  The present invention relates to a rain gutter used for an engine-driven working machine such as an engine-driven compressor, a generator, a welder, or a pump.

従来より筐体を有したエンジン駆動作業機は内部冷却のための外気取入口である吸気口と、冷却後の空気を放出する排風口とを有している。屋外で使用されるエンジン駆動作業機は筐体内部に配設した機器を雨水より保護するため吸気口、排風口および扉等に雨水入防止のための雨樋や雨水対策を施したダクト等を配設している。 2. Description of the Related Art Conventionally, an engine-driven work machine having a casing has an intake port that is an outside air intake port for internal cooling and an exhaust port that discharges air after cooling. Inlet for engine-driven working machine to protect the equipment that is disposed inside the housing from the rainwater to be used outdoors, air discharge opening and the door or the like ducts subjected to guttering and rainwater measures for rainwater immersion entering prevented Is arranged.

従来例の一例を特許文献1に示し、該発明を説明するにあたり呼称は特許文献1の表記により説明する。防音ケース内への雨水入を防ぎつつエンジン駆動作業機の設置スペースを大きくしないための考案として開示されている。 An example of a conventional example is shown in Patent Document 1, and in describing the invention, the designation is described by the notation of Patent Document 1. While preventing rainwater immersion entry into the soundproof case is disclosed as devised for not increasing the installation space of the engine-driven work machine.

エンジン駆動作業機の設置スペースを大きくしないために防音ケース上部の側壁面に形成した吸気口に該吸気口を覆うフードを形成する事無く、該吸気口の上部に雨樋を配設し、該雨樋より上部の筐体より伝わり落ちる雨水を該雨樋で受け止め、該吸気口より離れた所で雨水を落下させ、吸気口からの雨水入を防止している。 In order not to increase the installation space for the engine-driven work machine, a rain gutter is provided above the intake port without forming a hood that covers the intake port on the intake port formed on the side wall surface of the soundproof case. receiving an upper portion of the from the transmitted drops rainwater housing from the gutter in該雨gutter, to drop the rainwater at a distance from the intake port, thereby preventing rainwater immersion incoming from inlet.

また特許文献2に防音ケースの天井面に上を向いた排風口からの雨水入を防止する考案が開示されている。該考案によれば上を向いた排風口内に傾斜板を所定の間隔で複数個横設し、該傾斜板は所定の角度以内で傾いて降り注ぐ雨水に対して、必ず雨水が該傾斜板 に触突するようにし、触突した雨水を捕集する樋を該傾斜板の下端に形成し、該樋の両端より屋外に排出する考案が開示されている。 The idea of preventing rainwater immersion incoming from air discharge port facing upward to the ceiling surface of the soundproof case in Patent Document 2 is disclosed. According to the present invention, a plurality of inclined plates are installed at predetermined intervals in the exhaust outlet facing upward, and the inclined plates always fall into the inclined plates against rainwater that falls down within a predetermined angle. There has been disclosed a device in which a gutter that collects rainwater touching the gutter is formed at the lower end of the inclined plate and discharged to the outside from both ends of the gutter.

また他の従来例の一例として図6に設備として設置されるエンジン駆動作業機200の吸気ダクト230に雨樋を形成した構造を示し、図7に該吸気ダクト230の拡大図を示す。エンジン駆動作業機200は基礎枠体であるベース205上に冷却ファンを有したエンジン60とエンジン60に駆動される作業機本体50が筐体内に配設されている。  As an example of another conventional example, FIG. 6 shows a structure in which rain gutters are formed in an intake duct 230 of an engine-driven work machine 200 installed as equipment, and FIG. 7 shows an enlarged view of the intake duct 230. In the engine-driven work machine 200, an engine 60 having a cooling fan on a base 205, which is a basic frame body, and a work machine main body 50 driven by the engine 60 are disposed in a casing.

筐体上部に屋根部材210が配設され、該屋根部材210はエンジン駆動作業機200が大きいために屋根部材片210a、210b、210c、210d、210eの個々の部品で組み立てられている。屋根部材210の図示右端には冷却風を吸引する吸気口211が形成され、左端には冷却後の排風を外部に放出する排風口212が形成されている。  A roof member 210 is disposed on the upper part of the housing, and the roof member 210 is assembled by individual parts of the roof member pieces 210a, 210b, 210c, 210d, and 210e because the engine-driven work machine 200 is large. An air inlet 211 for sucking cooling air is formed at the right end of the roof member 210 in the figure, and an air exhaust port 212 for discharging the exhausted air after cooling to the outside is formed at the left end.

前記吸気口211には外部に放出される騒音を防止する目的と、吸引する空気に混じって吸引される雨水浸入の防止とを目的として、吸気ダクト230が開口部230aを下に向けて係止されている。該吸気ダクト230の下端側壁面には開口部を上に向けた樋230bが周囲に形成されていて、降雨時の雨水を捕集して、冷却風Q1の吸引力が比較的弱い吸気ダクト230の図示右側先端の両角部に吐き出す様になっている。  In the intake port 211, the intake duct 230 is locked with the opening 230a downward for the purpose of preventing noise emitted to the outside and preventing the intrusion of rainwater that is sucked into the sucked air. Has been. On the lower end side wall surface of the intake duct 230, a gutter 230b with an opening facing upward is formed around the intake duct 230. The intake duct 230 collects rainwater during rain and has a relatively weak suction force of the cooling air Q1. Is discharged to both corners at the right end of the figure.

天井面に降り注いだ雨水はより大きな水滴となって吸気ダクト230の側壁面を伝わり落ちて前記雨樋230bにより捕集される。該雨樋230b内でより大きく成長した水滴は活きよい良く樋内部を流れ、樋端部より塊となって地上に落下するので、前記開口部230aより吸引される事はない。  The rainwater that has poured onto the ceiling surface becomes larger water droplets, travels down the side wall surface of the intake duct 230, and is collected by the rain gutter 230b. Water droplets that grow larger in the rain gutter 230b vigorously flow through the inside of the gutter and fall to the ground as a lump from the gutter end, so that they are not sucked from the opening 230a.

水滴を含まない冷却風Q1が該吸気ダクト230内に吸引され、屋根部材210を通過した後にエンジン60に駆動される作業機本体50やエンジン60等を冷却する。このため作業機本体50やエンジン60等は水滴等を含まない冷却風にて冷却されるため不具合の発生を少なくする事ができる。吸熱後の冷却風は排風となって再び屋根部材210の図示しない内部通路,排風ダクト240へと送り出され、排風口240aより排風Q2となって大気に開放される。

Cooling air Q1 that does not contain water droplets is sucked into the intake duct 230, and after passing through the roof member 210, the work machine body 50, the engine 60, and the like that are driven by the engine 60 are cooled. For this reason, since the working machine main body 50, the engine 60, and the like are cooled by cooling air that does not contain water droplets or the like, the occurrence of problems can be reduced. The cooling air after the heat absorption is exhausted and sent again to the internal passage (not shown) of the roof member 210 and the exhaust duct 240, and is exhausted to the atmosphere as exhaust air Q2 from the exhaust port 240a.

多くの場合エンジン駆動作業機は使用する作業現場が固定される事は少なく、作業現場毎に頻繁に運ばれて使用される事が多い。かかる場合にエンジン駆動作業機は筐体よりダクト等の飛び出し部分が無い事が好まれる。またダクトや雨樋等は筐体より突き出ているため、エンジン駆動作業機のクレーン等による吊り上げ作業時や設置時に周辺の建造物や他のエンジン駆動作業機に衝打して、変形により自らの機能を果たさなくなったり、相手の構造物に損傷を与えてしまう事も有る。  In many cases, the engine-driven work machine is rarely fixed at the work site to be used, and is often carried and used at each work site. In such a case, it is preferred that the engine-driven work machine has no protruding portion such as a duct from the casing. Also, since ducts and gutters protrude from the housing, they are struck against surrounding buildings and other engine-driven work machines during lifting work or installation by an engine-driven work machine crane, etc. It may stop functioning or damage the opponent's structure.

雨樋を金属製として、筐体と雨樋とを溶接構造とした場合には接合面が塗装できずに錆の発生を抑えるために接合面をコーキングする必要が有る。また金属製雨樋を筐体にボルト等で固定する場合にも、雨樋が長かったりすると接合面に隙間ができる場合もあるのでコーキングの必要がある。  When the gutter is made of metal and the casing and gutter are welded, the joint surface cannot be painted and the joint surface needs to be caulked in order to suppress the occurrence of rust. In addition, when a metal gutter is fixed to the housing with a bolt or the like, if the gutter is long, a gap may be formed on the joint surface, and therefore caulking is necessary.

またエンジン駆動作業機が大型になると筐体全体が複数の構成部材に分割されていて、該構成部材のそれぞれがボルト等により結合されて1つの筐体となっている。該構成部材のうちで冷却風を吸引する吸気口が配設された構成部材(例えば屋根部材)は、更に細かに分割された同形状を成した複数の小構成部材片が横設されてボルト等の結合にて1つの構成部材となっている。  Further, when the engine-driven work machine becomes large, the entire housing is divided into a plurality of constituent members, and each of the constituent members is coupled by a bolt or the like to form one housing. Among the constituent members, the constituent member (for example, the roof member) provided with the air inlet for sucking the cooling air is further divided into a plurality of small constituent member pieces having the same shape and divided into bolts. It becomes one component member by the coupling | bonding.

前記吸気口が複数の小構成部材片に連続して形成されている場合には、雨水対策として雨樋を配設する場合は、横設された前記複数の小構成部材片の壁面に通して配設しなければならない。しかしながら同形状の複数の小構成部材片とは言え、外寸法は必ずしも同一に仕上がっていない場合がある。かかるばあいに該小構成部材片を横設してボルト等で結合されて組立誤差も加算されるので、当然接合面に段差が生じる。 When the intake port is formed continuously with a plurality of small component pieces, when a rain gutter is provided as a measure against rainwater, it is passed through the wall surfaces of the plurality of small component pieces arranged side by side. Must be installed. However although a plurality of small components pieces having the same shape, there is a case where the outer shape dimensions are not necessarily finished in the same. In such a case, the small constituent member pieces are installed side by side and coupled with bolts or the like, and an assembly error is added, so that a step is naturally formed on the joint surface.

この様な小構成部材片の接合面には雨水入防止対策として接合面全長に断面視で表面より盛り上がる様に円弧状のコーキングを施す事も有るため、更に接合面の平坦度が損なわれてしまう。かかる場合は、ボルトによる金属製の雨樋取付には、隙間調整を行った上で取付面の周囲をコーキングせねば成らい場合があり、取付に時間を要する。また隙間調整が不十分だと雨樋が変形してしまう事も有る。 Since there also be subjected to such a small component pieces cross section arcuate coking as rise from the surface at the bonding surface full length as input prevention immersion rainwater on the joint surface of, impaired further flatness of the joint surface End up. In such a case, a metal gutter mounting by bolts, may not always Nara If Ne Kokinguse around the mounting surface after performing the gap adjustment takes time to mount. In addition, if the gap adjustment is insufficient, the gutter may be deformed.

発明の効果The invention's effect

本発明は上述のように構成する事により、次のような効果を奏する。  The present invention has the following effects by being configured as described above.

雨樋を柔軟性を有した樹脂材で形成し、該雨樋の雨水排水に用いる凹型をした排水溝底面と該排水溝底面の下方に位置する雨樋底面との間の樹脂部材が塊として存在する部分の略中間領域に中空状の空隙を形成したので、該塊部を貫く方向の押圧力に対して反力を有しながら柔軟で復元力を期待した雨樋を提供する事ができる。  A gutter is formed of a flexible resin material, and a resin member between the bottom surface of the concave drainage groove used for drainage of rainwater and the bottom surface of the gutter located below the bottom surface of the drainage groove is formed as a lump. Since a hollow space is formed in a substantially intermediate region of the existing portion, it is possible to provide a rain gutter that is flexible and expected to have a restoring force while having a reaction force against a pressing force in a direction penetrating the lump portion. .

このためエンジン駆動作業機をクレーン等で吊り上げる作業時や設置時に周辺の建造物等に衝打しても、該雨樋自体や相手を傷つける事も少なく、また自らも復元力が優れているので変形により雨樋としての機能を失う事を軽減できる。  For this reason, even if the engine-driven work machine is lifted by a crane or the like and hits nearby buildings during installation, the rain gutter itself and the opponent are less likely to be damaged, and the resilience itself is excellent. Loss of function as a gutter can be reduced by deformation.

雨樋の取付面である前記垂直壁に対向する排水溝の排水溝外壁は、該排水溝底面の上方で排水溝幅が最大となる様に該排水溝外壁が外側に張り出して形成され、エンジン駆動作業機の筐体側壁面より一番突出した所と成っている。  The drainage groove outer wall of the drainage groove facing the vertical wall that is the attachment surface of the gutter is formed by projecting the drainage groove outer wall outwardly so that the drainage groove width is maximized above the bottom surface of the drainage groove, It is the most protruding part from the side wall of the housing of the drive work machine.

該構成により筐体側壁面に配設された雨樋の最大突出部が、略水平方向からの他の構造物に衝打されると、反力を有した雨樋の排水溝底面が前記平面状の垂直壁との交点を支点に全体が内側に回転するように変形する。この時該支点より上部の平面状の垂直壁は筐体側壁面に押圧される方向なので前記貼着された弾性部材が剥がれ事が無いので雨水が雨樋上部よりしみこむ事は無い。 With this configuration, when the maximum protrusion of the rain gutter disposed on the side wall surface of the casing is struck by another structure from a substantially horizontal direction, the bottom surface of the drain gutter having a reaction force is formed into the planar shape. It is deformed so that the whole rotates inward with the intersection with the vertical wall as a supporting point. Planar vertical wall of the upper than this time fulcrum is never so it is no Ru peeling the stuck by an elastic member so the direction to be pressed against the housing side wall rainwater soak than guttering top.

またこの時前記支点より下側の平面状の垂直壁は剥がれる方向の力が働くが仮に貼着した弾性部材が剥がれても、支点よりも上部が確実に貼着しているので上からの雨水のしみこみを懸念する必要は無い。  At this time, the planar vertical wall below the fulcrum works in the direction of peeling, but even if the adhered elastic member is peeled off, the upper part of the fulcrum is securely attached, so rainwater from above There is no need to worry about the intrusion.

雨樋の取付面である前記平面状の垂直壁に対向する前記排水溝外壁の外側表面下方に該雨樋底面との間を仕切る下側に向いた平板状の突起片を雨樋の長手方向に連続して形成したので、該外側表面に触突した雨水の水滴が該突起片を伝わり真下に落下するので雨樋底面を経て筐体側壁面に形成された吸気口へと伝わる事は無い。  A flat plate-like projecting piece that faces the bottom of the gutter bottom surface is formed below the outer surface of the drainage groove outer wall facing the flat vertical wall that is the attachment surface of the gutter. Since the raindrops touching the outer surface are transmitted along the protruding pieces and fall directly below, they are not transmitted to the intake port formed on the side wall surface of the casing through the bottom surface of the rain gutter.

前記取付面である平面状に形成された垂直壁の排水溝内側より、前記排水溝の底面の上側近傍に水平を成して筐体側壁面と該雨樋とを固定するボルトが配設されているので、前記排水溝の底面が前記平面状の垂直壁に交わる支点近傍は、該ボルトにより筐体側壁面に押圧されているので、該雨樋に水平方向の外力が加わった場合でも、確実に該支点部は安定的に押圧されている。  Bolts for fixing the housing side wall surface and the rain gutter are arranged horizontally from the inside of the drainage groove of the vertical wall formed as a flat surface as the mounting surface, near the upper side of the bottom surface of the drainage groove. Therefore, the vicinity of the fulcrum where the bottom surface of the drainage groove intersects the flat vertical wall is pressed against the side wall surface of the housing by the bolt, so even when a horizontal external force is applied to the gutter The fulcrum portion is stably pressed.

前記雨樋を柔軟性を有する樹脂材で形成したのでより貼着面である筐体側壁面の平坦度を気にせずに隙間無く貼着する事が可能となる。またエンジン駆動作業機が大型となり吸気口を形成する筐体部分が複数の小構成部材片で組み立てられ、該筐体接合面にコーキング処理が行われている場合は部分的に段差が生じるが、該段差を吸収して貼着できる雨樋を提供する事ができる。  Since the rain gutter is formed of a flexible resin material, it is possible to attach the gutter without any gaps without worrying about the flatness of the housing side wall surface, which is the affixing surface. In addition, when the engine-driven work machine is large and the casing part that forms the air inlet is assembled with a plurality of small component pieces, and the caulking process is performed on the casing joint surface, a step is partially generated, The rain gutter which can absorb and stick to this level | step difference can be provided.

雨樋が筐体面に確実に隙間無く貼着でき、該弾性部材は通常独立気泡体形成された多孔性材料を使用するので弾性部材自体の水の透過や隙間による水の透過を無くす事ができるのでコーキング作業を省く事ができ、仕上がりも良くなる。またボルト頭部が凹型溝の内部に配設されているので、外側より見えずに美観を損なう事は無い。 Rain gutters can be securely attached to the housing surface without gaps, and the elastic member usually uses a porous material formed of closed cells, so that it is possible to eliminate water permeation of the elastic member itself and water permeation through the gap. Because it can, you can omit the caulking work, and the finish will be better. In addition, since the bolt head is disposed inside the concave groove, it is not visible from the outside and the aesthetic appearance is not impaired.

前記上段フレーム片134と上段フレーム片135との側壁面に冷却空気を吸引する吸気口136、137が形成され、図示しない通風路を経て筐体内部を冷却して排風口131aより外部に放出される。該吸気口136、137の上方には雨樋80が前記上段フレーム片132から上段フレーム片135までを通して配設されている。  Air inlets 136 and 137 for sucking cooling air are formed on the side wall surfaces of the upper frame piece 134 and the upper frame piece 135, and the inside of the housing is cooled through a ventilation path (not shown) and discharged to the outside from the air exhaust port 131a. The A rain gutter 80 is arranged above the intake ports 136 and 137 from the upper frame piece 132 to the upper frame piece 135.

図2は図1で示したA−A断面図であり、図3は図2で示した雨樋80の拡大図であり以下併せて詳細に説明する。上段フレーム片135の側壁面135aには冷却風を吸引する吸気口137が雨水の浸入を阻止する斜板137aを有して形成されている。該吸気口137の上方に天井面等から流れ落ちる雨水を捕集する雨樋80が、弾性部材85を貼着したうえで上段フレーム片135の側壁面135aに配設されている。  2 is a cross-sectional view taken along the line AA shown in FIG. 1, and FIG. 3 is an enlarged view of the gutter 80 shown in FIG. 2, which will be described in detail below. An intake port 137 for sucking cooling air is formed on the side wall surface 135a of the upper frame piece 135 with a swash plate 137a for preventing rainwater from entering. A rain gutter 80 that collects rainwater flowing down from the ceiling surface or the like above the intake port 137 is disposed on the side wall surface 135 a of the upper frame piece 135 after the elastic member 85 is adhered.

図3に示すように、上段フレーム片135の側壁面135aに配設された雨樋80は、略凹型をした排水溝80eの開口部を上方に向け、該排水溝80eを形成する図示左端の壁面が平面状を成して排水溝の底面80fより下方に延びた垂直壁80aを形成している。該垂直壁80aの外壁面には独立気泡体で構成された弾性部材85の片面が貼設し、他面は側壁面135aに貼着している。さらにボルト92にて側壁面135aに固設されたナット93との間で雨樋を螺持している。  As shown in FIG. 3, the rain gutter 80 disposed on the side wall surface 135a of the upper frame piece 135 has a substantially concave drainage groove 80e facing upward, and forms the drainage groove 80e. The wall surface is flat and forms a vertical wall 80a extending downward from the bottom surface 80f of the drainage groove. One surface of the elastic member 85 made of closed cells is attached to the outer wall surface of the vertical wall 80a, and the other surface is attached to the sidewall surface 135a. Further, a rain gutter is screwed between the bolt 92 and a nut 93 fixed to the side wall surface 135a.

排水溝底面80fと前記垂直壁80a下端に連なる雨樋80の底面80kとの間に囲まれる略中間領域に中空状の空隙80cが雨樋80の長手方向に通して形成されている。垂直壁80aに対向する排水溝外壁80dは、排水溝の底面80fの図示右側端部に連なり上方に向かいながら外側に拡がるように排水溝80eの幅を広げて最大溝幅を形成した後は、上方位置で排水溝80eの幅を狭めている。  A hollow space 80c is formed in the longitudinal direction of the rain gutter 80 in a substantially intermediate region surrounded by the drain groove bottom face 80f and the bottom face 80k of the rain gutter 80 connected to the lower end of the vertical wall 80a. After the drainage groove outer wall 80d facing the vertical wall 80a is connected to the right end of the bottom surface 80f of the drainage groove and extends outward while extending upward, the drainage groove 80e is widened to form the maximum groove width. The width of the drainage groove 80e is narrowed at the upper position.

前記排水溝外壁80dの下側は前記雨樋の底面80kへと延びている。排水溝外壁80dと雨樋底面80kとの境には、該排水溝外壁80dの表面に沿って流れ落ちる水滴を下側に落下させる下側に向いた平板状の突起片80gが形成されている。  The lower side of the drain groove outer wall 80d extends to the bottom surface 80k of the gutter. At the boundary between the drain groove outer wall 80d and the rain gutter bottom surface 80k, a flat plate-shaped projecting piece 80g facing downward is formed to drop water drops flowing down along the surface of the drain groove outer wall 80d.

排水溝外壁80dの内側より図示矢印F1から矢印F2の方向に力を加えると排水溝外壁80dは想像線で示す排水溝外壁80jの如く倒れるのでボルト92の挿入を行う事ができ、矢印F2,F1の方向の力を取り去ると排水溝外壁80jは実線で示した元の位置である排水溝外壁80dに戻る。  When a force is applied from the inside of the drain groove outer wall 80d in the direction of the arrow F1 to the arrow F2, the drain groove outer wall 80d falls down like a drain groove outer wall 80j indicated by an imaginary line, so that the bolt 92 can be inserted. When the force in the direction F1 is removed, the drain groove outer wall 80j returns to the drain groove outer wall 80d, which is the original position indicated by the solid line.

排水溝底面80fの下方は略中央部に中空状の空隙80cを有した塊部80bが形成されている。該塊部80bは他の雨樋部分に比較して外力に対する反発力が有り衝撃に対して緩衝材として働く。エンジン駆動作業機の移設時や搬送時に伴う触突による外力に対して機械の保護に役立ち、また相手の構造物に対して損傷を与える事も少なくなる。この様に該雨樋80は緩衝材としての機能を有した雨樋となっている。  Below the drain groove bottom surface 80f, a lump portion 80b having a hollow gap 80c is formed in a substantially central portion. The lump 80b has a repulsive force against an external force as compared with other rain gutters and acts as a shock absorbing material against an impact. It helps to protect the machine against external forces caused by the bumps that occur when the engine-driven work machine is moved or transported, and also reduces damage to the counterpart structure. Thus, the gutter 80 is a gutter having a function as a buffer material.

図4は図1で示したP矢視図で有るが、雨樋80の取付前の状態を示している。結合される上段フレーム片134と上段フレーム片135との間には製作上の寸法誤差が有ったり、組立時に発生する該上段フレーム片の側壁面134aと上段フレーム片の側壁面135aとの間のずれにより段差d1が生じる事がある。  4 is a view taken in the direction of arrow P shown in FIG. 1 and shows a state before the rain gutter 80 is attached. There is a manufacturing dimensional error between the upper frame piece 134 and the upper frame piece 135 to be joined, or between the side wall surface 134a of the upper frame piece and the side wall surface 135a of the upper frame piece generated during assembly. The step d1 may occur due to the deviation.

また両上段フレーム片間の結合部には雨水対策としてコーキング部材160が結合部に沿って連続的に塗布され、該コーキング部材の断面は表面より円弧状に盛り上がるように施工されている。前記段差d1が生じた部分には該段差d1をなだらかに覆うコーキング部材160の盛り上がり部160aが形成されている。  Further, a caulking member 160 is continuously applied along the joint portion as a rainwater countermeasure at the joint portion between both upper frame pieces, and the cross section of the caulking member is constructed so as to rise in an arc shape from the surface. A raised portion 160a of a caulking member 160 that gently covers the step d1 is formed at the portion where the step d1 occurs.

図5は図4に対して雨樋80を取り付けた状態を表している。段差d1を有した前記上段フレーム片の側壁面134aと上段フレーム片の側壁面135aとに跨り雨樋80が、略凹型をした排水溝80eの開口部を上方に向け、合成ゴム製の弾性部材85が雨樋80の前記垂直壁80aに貼設されて上段フレームの各側壁面に沿うように密着状態で配設されている。  FIG. 5 shows a state in which a gutter 80 is attached to FIG. An elastic member made of synthetic rubber with a gutter 80 facing the opening of the substantially concave drainage groove 80e across the side wall surface 134a of the upper frame piece having the step d1 and the side wall surface 135a of the upper frame piece. 85 is affixed to the vertical wall 80a of the rain gutter 80 and is arranged in close contact with each side wall surface of the upper frame.

該雨樋80は可塑剤を加えて所定の硬度にした塩化ビニル樹脂で形成され、前記垂直壁80aに貼設された合成ゴム製の弾性部材85と共に柔軟性を有しながら取付面である上段フレームの各側壁面の変形や段差部を吸収している。取付面の段差部やコーキング部の盛り上がり部160aの密着状態を確実にするため、排水溝80eの内側よりボルト92を筐体側に固着されたナット93に挿通し固定している。  The rain gutter 80 is formed of a vinyl chloride resin having a predetermined hardness by adding a plasticizer. The gutter 80 has an upper surface which is a mounting surface while having flexibility together with an elastic member 85 made of synthetic rubber stuck to the vertical wall 80a. It absorbs deformations and steps on each side wall of the frame. In order to ensure the close contact state of the stepped portion of the mounting surface and the raised portion 160a of the caulking portion, the bolt 92 is inserted and fixed from the inside of the drainage groove 80e to the nut 93 fixed to the housing side.

雨樋80や上段フレームの段差部d1及びコーキング部材160形状を説明するに当たり各要部は誇張して図示している。また実施例では結合された複数の上段フレーム片に跨るように雨樋80を配設した実例を開示したが平坦な1つの部材で形成された取付面でも効果を有する事は言うまでもない。また前記貼設する弾性部材85は、1つの部材で形成された平坦な取付面で有る場合は厚さの薄い両面テープ等を用いる事も可能である事は言うまでもない。  In describing the shape of the rain gutter 80, the stepped portion d1 of the upper frame, and the shape of the caulking member 160, each main portion is exaggerated. Further, in the embodiment, an example in which the rain gutter 80 is disposed so as to straddle a plurality of joined upper frame pieces is disclosed, but it goes without saying that the mounting surface formed by one flat member is also effective. Needless to say, when the elastic member 85 to be attached is a flat mounting surface formed of a single member, a thin double-sided tape or the like can be used.
