For example, the present invention is attached to the lower side of a veranda, balcony, entrance porch, etc. This is related to a gutter catcher that drains rainwater from above.

従来から、図５に示すように、上方へ矩形状に開口した箱型のます本体１と、ます本体１の上方開口部２に嵌着される矩形状の蓋体３とを備えた雨樋集水ますは知られている（特許文献１）。この雨樋集水ますは、ベランダ、バルコニー、玄関ポーチ等の下側面となる取付面に固定され、これ等の上側から雨水等の排水を流下案内するために同取付面に垂下突設された排水管が蓋体３を貫通され、この排水管から流下する排水をます本体１内に受けるものである。 Conventionally, as shown in FIG. 5, a rain gutter having a box-shaped main body 1 opened in a rectangular shape upward and a rectangular lid body 3 fitted to the upper opening 2 of the main body 1. Masashi is known (Patent Document 1). This rain gutter collecting basin was fixed to the mounting surface on the lower side of the veranda, balcony, entrance porch, etc., and was suspended from the upper side of these mounting surfaces to guide the drainage of rainwater and the like. A drain pipe is penetrated through the lid 3 and receives the waste water flowing down from the drain pipe into the main body 1.

この場合、蓋体３は軟質材で形成されており、施工現場において、取付面から垂下する排水管に対応させて排水管導入口５を切断除去して形成するものである。また、ます本体１の上方開口部２の開口縁部分には対向する位置に一対の取付孔７が配設されており、この上方開口部２に前記蓋体３を嵌着した後、同取付孔７に下方から挿通される固定具６によって取付面に固定される。そして、ます本体１の底部分には落とし口筒部１８が垂設されており、前記ます本体１内に受けられた排水は同落とし口筒部１８から竪樋等を介して排水除去される。

JP-A-7-113303

しかしながら、上記従来例である雨樋集水ますにあっては、取付面から垂下する排水管に対応して排水管導入口５が形成されるものではあるが、この排水管導入口５は施工現場において切断除去して形成されるものであり、その作業が面倒である。しかも、ます本体１の上方開口部２の開口縁部分に形成された取付孔７に下方から挿通される固定具６によって取付面に固定されるものであるため、下方に同取付孔７や固定具６等の固定手段が露出して体裁は良くない。また、前記固定手段が外側に存在するためます本体１の外形状は小さくなり、その分だけ排水容量が減少してしまう。 However, in the rain gutter collecting basin which is the conventional example, the drain pipe introduction port 5 is formed corresponding to the drain pipe hanging from the mounting surface. It is formed by cutting and removing at the site, and the work is troublesome. Moreover, since it is fixed to the mounting surface by a fixture 6 inserted from below into the mounting hole 7 formed in the opening edge portion of the upper opening 2 of the main body 1, the mounting hole 7 and the fixing are fixed downward. Fixing means such as the tool 6 are exposed and the appearance is not good. Further, since the fixing means is present on the outside, the outer shape of the main body 1 becomes smaller, and the drainage capacity decreases accordingly.

そこで、図６、７に示すように、上方へ矩形状に開口した箱型のます本体１と、ます本体１の上方開口部２に嵌着される矩形状の蓋体３とを備え、蓋体３の中程に上方から排水管４が挿入される排水管導入口５を予め開口形成した雨樋集水ますが提案されている。この場合、蓋体３の四隅には固定具が挿通される取付孔７が配置穿設されており、取付孔７に挿通される固定具で蓋体３が建物の取付面８に固定されることで同蓋体３が嵌着されるます本体１と共に取付支持される。 Therefore, as shown in FIGS. 6 and 7, a box-shaped rectangular main body 1 opened in a rectangular shape upward, and a rectangular lid body 3 fitted to the upper opening 2 of the main body 1 are provided. It has been proposed to collect rain gutters in which a drain pipe inlet 5 into which a drain pipe 4 is inserted from above is formed in the middle of the body 3 in advance. In this case, mounting holes 7 through which the fixtures are inserted are arranged and drilled at the four corners of the lid 3, and the lid 3 is fixed to the mounting surface 8 of the building with the fixtures inserted through the mounting holes 7. Thus, the lid 3 is attached and supported together with the main body 1 to which the lid 3 is fitted.

そして、排水管導入口５は蓋体３の外形に沿った略矩形状に形成されており、予め同排水管導入口５が形成されているので施工現場での作業は容易となる。また、施工現場においては、取付面８に垂下突設された排水管４を排水管導入口５に挿入した状態で、蓋体３を取付孔７に下方から挿通される固定具６によって同取付面８に固定し、この固定された蓋体３にます本体１を嵌着させて取り付けることができる。この場合、取付孔７や固定具等の固定手段がます本体１により下方から覆われれて露出せず、外観は良好に納まり、同ます本体１の排水容量も大きく確保される。 And the drain pipe inlet 5 is formed in the substantially rectangular shape along the external shape of the cover body 3, Since the drain pipe inlet 5 is previously formed, the operation | work at a construction site becomes easy. At the construction site, the drainage pipe 4 projecting from the mounting surface 8 is inserted into the drainage pipe inlet 5, and the lid 3 is attached by the fixture 6 inserted from below into the mounting hole 7. The main body 1 can be fitted and attached to the fixed lid 3 by being fixed to the surface 8. In this case, the fixing means such as the mounting hole 7 and the fixing tool are covered with the main body 1 from the lower side and are not exposed, the appearance is satisfactorily accommodated, and the drainage capacity of the main body 1 is also ensured.

ところが、この場合、図６（ａ）に示すように、略矩形状に形成された排水管導入口５の各辺縁５ａは直線状であり、同排水管導入口５の開口面積が小さくなっている。そのため、排水管４の径が大きい場合や二本の排水管４が垂下突設されている場合に、これ等の排水管４を排水管導入口５に挿入することができずに対応不能となることがあった。そしてまた、図７に示すように、排水管４が取付面８のコーナーに近接した位置で垂下突設されている場合には、蓋体３の排水管導入口５の角部分が同排水管４に当接してしまい、同取付面８のコーナーから蓋体３が外側に突出した状態で取り付けられ、施工仕上がり外観が良好に納まらないこともあった。 However, in this case, as shown in FIG. 6A, each edge 5a of the drainage pipe inlet 5 formed in a substantially rectangular shape is linear, and the opening area of the drainage pipe inlet 5 is reduced. ing. Therefore, when the diameter of the drainage pipe 4 is large or when the two drainage pipes 4 are suspended, these drainage pipes 4 cannot be inserted into the drainage pipe introduction port 5 and cannot be handled. There was. Further, as shown in FIG. 7, when the drainage pipe 4 is provided in a projecting manner at a position close to the corner of the mounting surface 8, the corner portion of the drainage pipe inlet 5 of the lid 3 is the drainage pipe. 4 and is attached in a state where the lid 3 protrudes outward from the corner of the mounting surface 8, and the construction finish appearance may not fit well.

本願発明は、上記背景技術に鑑みてなされたもので、その課題は、取付面に垂下突設される排水管の種々の形態に対応し易く、仕上がり外観良く納まるよう簡単に施工することができる雨樋集水ますを提供することである。 The present invention has been made in view of the above-described background art, and the problem is that it easily corresponds to various forms of drainage pipes projecting from the mounting surface, and can be easily constructed to fit in the finished appearance. It is to provide gutter collection water.

In the middle of the lid body, drainage pipe inlets into which drainage pipes are inserted from above are formed. At the four corners of the lid body, mounting holes through which fixtures are inserted are arranged and drilled. The lid is fixed to the mounting surface of the building with a fixture that is inserted into the gutter. It is formed in a substantially rectangular shape along the outer shape of the body, and each edge of this substantially rectangular drainage pipe inlet is bent so as to bulge outward, and both adjacent edges are corner portions of the drainage pipe inlet. It is formed so as to spread at an obtuse angle.

本願請求項２記載の発明は、請求項１記載の雨樋集水ますにおいて、四隅の取付孔を避けるように排水管導入口の各角部分を略円弧状に面取りした形状として形成したことを特徴とする。 The invention described in claim 2 of the present application is that the drainage collecting tank according to claim 1 is formed as a shape in which each corner portion of the drainage pipe inlet is chamfered in a substantially arc shape so as to avoid the mounting holes at the four corners. Features.

本願請求項１記載の発明である雨樋集水ますにおいては、排水管導入口を工場等で予め形成しておくことができるので、これにより施工現場での作業は容易となる。また、施工現場においては、取付面に垂下突設された排水管を排水管導入口に挿入した状態で、取付孔に下方から挿通される固定具によって蓋体を同取付面に固定し、この固定された蓋体にます本体を嵌着させて簡単に取り付けることもできる。この場合に、取付孔や固定具等の固定手段をます本体で下方から覆い隠すことができ、これにより外観を良好に納めることができ、同ます本体の排水容量を大きく確保することもできる。 In the rain gutter collecting basin which is the invention described in claim 1 of the present application, the drain pipe introduction port can be formed in advance in a factory or the like, so that the work at the construction site is facilitated. In addition, at the construction site, with the drain pipe projecting from the mounting surface inserted into the drain pipe inlet, the lid is fixed to the mounting surface with a fixture inserted from below into the mounting hole. It is also possible to easily attach the main body to the fixed lid body. In this case, fixing means such as a mounting hole and a fixing tool can be covered with the main body from the lower side, so that the appearance can be satisfactorily accommodated, and the drainage capacity of the main body can be kept large.

しかも、蓋体の外形に沿って略矩形状に形成された排水管導入口の各辺縁を外側へ膨らむように曲成して、隣合う両辺縁を同排水管導入口の角部分から鈍角に広がるように形成しているので、排水管を同排水管導入口にその角部分に近付けた状態で挿入することができる。そのため、例えば、二本の排水管を対角に配置して排水管導入口に挿入したり、一本でも径の大きな排水管を同排水管導入口に挿入したりして、取付面に垂下突設されるこれ等排水管の種々の形態に対応し易くなる。また、排水管が取付面のコーナーに近接した位置で垂下突設されている場合に、排水管を排水管導入口にその角部分に近付けた状態で挿入することにより、蓋体を同取付面のコーナーから外側に突出しないように取り付けることができ、施工仕上がり外観に支障を来たさない。 Moreover, each edge of the drainage pipe inlet formed in a substantially rectangular shape along the outer shape of the lid is bent so as to bulge outward, and both adjacent edges are obtuse from the corner of the drainage pipe inlet. Therefore, the drainage pipe can be inserted into the drainage pipe inlet in a state of being close to the corner portion. Therefore, for example, arrange two drain pipes diagonally and insert them into the drain pipe inlet, or insert one drain pipe with a large diameter into the drain pipe inlet, It becomes easy to cope with various forms of these drainage pipes protruding. In addition, when the drain pipe is droopingly projecting at a position close to the corner of the mounting surface, the drain pipe is inserted into the drain pipe inlet in the state of being close to the corner portion, so that the lid body is attached to the mounting surface. It can be mounted so that it does not protrude outward from the corner of the machine, so that the appearance of the finished work will not be hindered.

本願請求項２記載の発明である雨樋集水ますにおいては、特に、排水管導入口の各角部分を略円弧状に面取りした形状として四隅の取付孔を避けているので、略矩形状に形成される排水管導入口を全体的に広げてその開口面積をより大きく確保することができ、取付面に垂下突設される排水管の種々の形態への対応は更に容易となる。 In the rain gutter collecting basin according to claim 2 of the present application, in particular, each corner portion of the drainage pipe inlet is chamfered in a substantially arc shape so as to avoid the mounting holes at the four corners. The formed drainage pipe introduction port can be widened as a whole to ensure a larger opening area, and it becomes easier to cope with various forms of drainage pipes projecting from the mounting surface.

図１〜４は、本願請求項１、２全てに対応した一実施形態を示している。この実施形態の雨樋集水ますは、上方へ矩形状に開口した箱型のます本体１と、ます本体１の上方開口部２に嵌着される矩形状の蓋体３とを備えている。そして、蓋体３の中程には上方から排水管４が挿入される排水管導入口５が開口形成され、同蓋体３の四隅には固定具６が挿通される取付孔７が配置穿設されており、取付孔７に挿通される固定具６で蓋体３が建物の取付面８に固定されることで同蓋体３が嵌着されるます本体１と共に取付支持されるものである。 1 to 4 show an embodiment corresponding to all of claims 1 and 2 of the present application. The rain gutter collecting basin of this embodiment includes a box-shaped rectangular main body 1 that opens upward in a rectangular shape, and a rectangular lid 3 that is fitted into the upper opening 2 of the main body 1. . A drainage pipe introduction port 5 into which the drainage pipe 4 is inserted from above is formed in the middle of the lid body 3, and mounting holes 7 through which the fixtures 6 are inserted are arranged at the four corners of the lid body 3. The lid 3 is fixed to the mounting surface 8 of the building with a fixture 6 inserted through the mounting hole 7 and is attached and supported together with the main body 1 to which the lid 3 is fitted. is there.

この実施形態の雨樋集水ますでは、図２に示すように、排水管導入口５を蓋体３の外形に沿った略矩形状に形成し、この略矩形状の排水管導入口５の各辺縁５ａを外側へ膨らむように曲成して、隣合う両辺縁５ａを同排水管導入口５の角部分から鈍角αに広がるように形成している。また、この実施形態の雨樋集水ますでは、四隅の取付孔７を避けるように排水管導入口５の各角部分を略円弧状に面取りした形状Ｒとして形成してもいる。 In the rain gutter collecting basin of this embodiment, as shown in FIG. 2, the drainage pipe inlet 5 is formed in a substantially rectangular shape along the outer shape of the lid 3, and the drainage pipe inlet 5 of the substantially rectangular drainage pipe 5 is formed. Each edge 5a is bent so as to bulge outward, and both adjacent edges 5a are formed so as to spread from the corner portion of the drain pipe inlet 5 to an obtuse angle α. Further, in the rain gutter collecting basin of this embodiment, each corner portion of the drainage pipe introduction port 5 is formed as a shape R that is chamfered in a substantially arc shape so as to avoid the mounting holes 7 at the four corners.

以下、この実施形態の雨樋集水ますをより具体的詳細に説明する。この実施形態の雨樋集水ますは、図１、４に示すように、ベランダ、バルコニー、玄関ポーチ等の下側面となる取付面８に固定され、これ等の上側から雨水等の排水を流下案内するために同取付面８に垂下突設された排水管４が蓋体３の排水管導入口５を貫通され、この排水管４から流下する排水をます本体１内に受けるものである。そして、ます本体１の底部分には落とし口９が形成され、この落とし口９には接続筒体１０が取り付けられるものであり、前記ます本体１内に受けられた排水は同接続筒体１０を介して接続される竪樋１１へと排水除去される。 Hereinafter, the rain gutter collecting basin of this embodiment will be described in more detail. As shown in FIGS. 1 and 4, the rain gutter collecting basin of this embodiment is fixed to a mounting surface 8 which is a lower side of a veranda, a balcony, a front porch, etc., and drains such as rain water flow down from above. A drainage pipe 4 projecting from the mounting surface 8 for guiding is passed through the drainage pipe inlet 5 of the lid 3, and drainage flowing down from the drainage pipe 4 is received in the main body 1. Further, a drop 9 is formed at the bottom of the main body 1, and a connecting cylinder 10 is attached to the drop 9, and the drainage received in the main body 1 is connected to the connecting cylinder 10. The drainage is removed to the trough 11 connected through the.

ます本体１は外形が略直方体形状で下狭まりの箱型であり、その上面全体が矩形状の上方開口部２として形成され、その底部には前記落とし口９が形成されて、合成樹脂で一体に射出成形されたものである。そして、落とし口９には前記接続筒体１０が着脱自在に取り付けられ、この接続筒体１０を介して竪樋１１が同落とし口９から垂下されるように接続される。また、ます本体１の上方開口部２には、全周にわたって外方へ折曲したフランジ片１２が一体に形成されている。 The main body 1 has a substantially rectangular parallelepiped shape and has a box shape with a narrow bottom. The entire upper surface is formed as a rectangular upper opening 2, and the drop 9 is formed at the bottom of the main body 1. Are injection molded. The connecting cylinder 10 is detachably attached to the drop port 9, and the flange 11 is connected to the drop port 9 via the connection cylinder 10. Further, the upper opening 2 of the main body 1 is integrally formed with a flange piece 12 bent outward over the entire circumference.

蓋体３は前記ます本体１の上方開口部２と略合致する矩形状に形成され、その中程にはその大部分を占める大きさで同蓋体３の外形に沿った略矩形状の排水管導入口５が開口形成されており、合成樹脂で一体に射出成形されたものである。図１に示すように、蓋体３の四隅の片辺側には係止片１３が配設されており、図３に示すように、同係止片１３は断面略Ｌ字状に折曲するように垂下されていて、前記フランジ片１２が各係止片１３に係止され、これにより前記ます本体１はその上方開口部２で蓋体３に対して着脱自在に嵌着固定される。この場合、上方開口部２の四隅が蓋体３の四隅から外れた状態で同蓋体３の下側にます本体１は配置され、この状態から同ます本体１を回動させることにより前記フランジ片１２が各係止片１３に係止される。 The lid 3 is formed in a rectangular shape that substantially matches the upper opening 2 of the main body 1, and has a substantially rectangular drainage along the outer shape of the lid 3 in the middle of the lid 3. A tube introduction port 5 is formed as an opening and is integrally injection-molded with a synthetic resin. As shown in FIG. 1, locking pieces 13 are arranged on one side of the four corners of the lid 3. As shown in FIG. 3, the locking pieces 13 are bent into a substantially L-shaped cross section. The flange piece 12 is locked to each locking piece 13 so that the main body 1 is detachably fitted and fixed to the lid 3 at the upper opening 2 thereof. . In this case, the main body 1 is arranged on the lower side of the lid 3 with the four corners of the upper opening 2 being disengaged from the four corners of the lid 3, and the flange 1 is rotated by rotating the main body 1 from this state. The piece 12 is locked to each locking piece 13.

蓋体３には前記各係止片１３に対応した個所に抜き開口１４が形成されており、これは射出成形時の型抜きのために必要な構造である。そして、蓋体３の四隅には固定具６が挿通される取付孔７が配置穿設されており、取付孔７に挿通されるネジ、釘等の固定具６によって同蓋体３は取付面８に固定され、これにより同蓋体３が嵌着されるます本体１と共に取付支持される。また、蓋体３の外周縁には全周にわたって上方へ突出した凸リブ１５が立設されると共に、前記取付孔７の周囲が上方へ突出したボス１６として立設されており、このボス１６の上端及び同凸リブ１５の上縁が取付面８に当接される。 The lid 3 is formed with a punching opening 14 at a position corresponding to each of the locking pieces 13, and this is a structure necessary for die cutting at the time of injection molding. Mounting holes 7 through which the fixtures 6 are inserted are arranged and drilled at the four corners of the lid 3, and the lid 3 is attached to the mounting surface by the fixtures 6 such as screws and nails inserted through the mounting holes 7. It is fixed to 8 and is attached and supported together with the main body 1 to which the lid 3 is fitted. Further, a convex rib 15 projecting upward is provided on the outer peripheral edge of the lid body 3 and a boss 16 projecting upward around the mounting hole 7 is provided. And the upper edge of the convex rib 15 are in contact with the mounting surface 8.

この場合、取付孔７は前記排水管導入口５と抜き開口１４との間に位置しており、同取付孔７が形成される前記ボス１６の部位は蓋体３に対して上下に弾性変形し易くなっている。そのため、前記ボス１６の上端及び凸リブ１５の上縁が取付面８に安定した状態で当接されて、蓋体３は同取付面８に対しがたつきなく確実に固定される。また、蓋体３の排水管導入口５の口縁（四辺縁５ａ）全周には内下方へと湾曲状に傾斜して垂下した口縁片１７が形成されており、この口縁片１７にガイドされて排水管４はスムーズに挿入され安定的に保持される。なお、蓋体３において、前記口縁片１７だけを弾性に富んだ軟質材で形成してもよい。 In this case, the mounting hole 7 is located between the drain pipe introduction port 5 and the extraction opening 14, and the portion of the boss 16 where the mounting hole 7 is formed is elastically deformed up and down with respect to the lid 3. It is easy to do. Therefore, the upper end of the boss 16 and the upper edge of the convex rib 15 are in contact with the mounting surface 8 in a stable state, and the lid 3 is securely fixed to the mounting surface 8 without rattling. Further, a lip piece 17 is formed on the entire periphery of the drainage pipe introduction port 5 of the lid 3 (four side edges 5a) so as to be inclined downwardly inwardly. The drain pipe 4 is smoothly inserted and stably held. In the lid 3, only the lip piece 17 may be formed of a soft material rich in elasticity.

更に、前記蓋体３において、図２に示すように、前記排水管導入口５が同蓋体３の中程にその外形に沿った略矩形状に形成されている。また、略矩形状の排水管導入口５の各辺縁５ａは外側へ膨らむよう湾曲状に曲成されており、隣合う両辺縁５ａが同排水管導入口５の角部分から鈍角αに広がるように形成されて各辺縁５ａは連続している。そして、前記四隅の取付孔７を避けるように、排水管導入口５の各角部分は略円弧状に面取りした形状Ｒとして形成されており、この面取りした形状Ｒの略円弧状両端における両接線が前記鈍角αとして広がるものである。 Further, in the lid 3, as shown in FIG. 2, the drain pipe inlet 5 is formed in a substantially rectangular shape along the outer shape in the middle of the lid 3. Moreover, each edge 5a of the substantially rectangular drain pipe inlet 5 is curved so as to swell outward, and both adjacent edges 5a spread from the corner of the drain pipe inlet 5 to an obtuse angle α. Thus, each edge 5a is continuous. And each corner | angular part of the drainage pipe inlet 5 is formed as the shape R which chamfered in the substantially arc shape so that the attachment hole 7 of the said four corners may be avoided, and both tangents in the substantially arc-shaped both ends of this chamfered shape R Is spread as the obtuse angle α.

したがって、この実施形態の雨樋集水ますにおいては、排水管導入口５を工場等で予め所定の大きさ形状に形成しておくことができ、図５に示した従来例のように、施工現場において排水管導入口５を切断除去して形成する必要はないので、施工現場での取付作業が容易となる。また、施工現場においては、取付面８に垂下突設された排水管４を排水管導入口５に挿入した状態で、取付孔７に下方から挿通される固定具６によって蓋体３を同取付面８に固定し、この固定された蓋体３にます本体１を嵌着させて簡単に取り付けることもできる。この場合、取付孔７や固定具６等の固定手段がます本体１で下方から覆い隠されて外観良好に納まり、同ます本体１の排水容量も大きく確保される。 Therefore, in the rain gutter collecting basin of this embodiment, the drain pipe introduction port 5 can be formed in a predetermined size in advance in a factory or the like, and as in the conventional example shown in FIG. Since it is not necessary to cut and remove the drain pipe introduction port 5 at the site, the installation work at the construction site is facilitated. Further, at the construction site, the lid 3 is attached by the fixture 6 inserted from below into the mounting hole 7 with the drain pipe 4 projecting from the mounting surface 8 inserted into the drain pipe inlet 5. The main body 1 can be easily attached by being fixed to the surface 8 and the main body 1 being fitted to the fixed lid 3. In this case, the fixing means such as the mounting hole 7 and the fixing tool 6 are covered with the main body 1 from the lower side so that the appearance is good and the drainage capacity of the main body 1 is ensured to be large.

しかも、蓋体３の外形に沿って略矩形状に形成された排水管導入口５の各辺縁５ａを外側へ膨らむように曲成することにより、隣合う両辺縁５ａは同排水管導入口５の角部分から鈍角αに広がるように形成されているので、排水管４を同排水管導入口５にその角部分に近付けた状態で挿入することができる。そのため、例えば、図２、４に示すように、二本の少し太めの排水管４（この場合は外径６０ｍｍ）を対角に配置して排水管導入口５に挿入することができ、一本でも径の相当に大きな排水管４を同排水管導入口５に挿入することもでき、取付面８に垂下突設されるこれ等排水管４の種々の形態に対応し易くなっている。 In addition, by bending each edge 5a of the drain pipe inlet 5 formed in a substantially rectangular shape along the outer shape of the lid 3 so as to bulge outward, both adjacent edges 5a are connected to the drain pipe inlet. The drainage pipe 4 can be inserted into the drainage pipe introduction port 5 in a state of being close to the corner part since it is formed so as to spread from the corner part 5 to the obtuse angle α. Therefore, for example, as shown in FIGS. 2 and 4, two slightly thicker drain pipes 4 (in this case, an outer diameter of 60 mm) can be diagonally arranged and inserted into the drain pipe inlet 5. Also in this book, the drain pipe 4 having a considerably large diameter can be inserted into the drain pipe introduction port 5, and it is easy to cope with various forms of these drain pipes 4 projecting from the mounting surface 8.

また、図４に示すように、排水管４が取付面８のコーナーに近接した位置で垂下突設されている場合（この場合は排水管４が二本であるが一本の場合も同様）に、排水管４を排水管導入口５にその角部分に近付けた状態で挿入することにより、蓋体３を同取付面８のコーナーから外側に突出しないように取り付けることができ、施工仕上がり外観に支障を来たさない。 Moreover, as shown in FIG. 4, when the drain pipe 4 is droopingly projecting at a position close to the corner of the mounting surface 8 (in this case, there are two drain pipes 4 but the same applies to one). In addition, by inserting the drainage pipe 4 into the drainage pipe inlet 5 in a state close to the corner portion, the lid 3 can be attached so as not to protrude outward from the corner of the mounting surface 8, and the finished appearance of the construction It will not interfere with.

更に、この実施形態の雨樋集水ますにおいては、排水管導入口５の各角部分を略円弧状に面取りした形状Ｒとして四隅の取付孔７を避けているので、略矩形状に形成される排水管導入口５の口縁（四辺縁５ａ）を全体的に広げてその開口面積をより大きく確保することができ、取付面８に垂下突設される排水管４の種々の形態への対応は極めて容易なものとなっている。 Furthermore, in the rain gutter collecting basin of this embodiment, the corners of the drain pipe inlet 5 are chamfered in a substantially arc shape as the shape R so that the four corner mounting holes 7 are avoided. The opening edge (four side edges 5a) of the drain pipe introduction port 5 can be broadened as a whole to ensure a larger opening area, and the drain pipe 4 that projects from the mounting surface 8 to various forms can be obtained. Correspondence is extremely easy.
