Description

本発明は、屋根やバルコニーから流れ落ちる雨水を軒樋で受け下方に排水する雨樋装置に関する。   The present invention relates to a rain gutter apparatus that receives rain water flowing down from a roof or a balcony with an eaves and drains it downward.

従来、屋根の軒先から流れ落ちる雨水を軒樋で受け下方に排水する雨樋装置として、例えば、図３に示すように家屋の屋根の軒先に取付けられた軒樋ａに呼び樋ｂや竪樋ｃを竪樋継手ｄによって接続し、外壁ｅに沿って垂下させて地中に埋設された排水管ｆに接続しているのが一般的である。   Conventionally, as a rain gutter device that receives rain water flowing down from the eaves of the roof and drains it downward, for example, as shown in FIG. 3, the eaves a attached to the eaves of the roof of the house are called b and c Are generally connected by a saddle joint d and suspended along the outer wall e and connected to a drain pipe f buried in the ground.

ところで、上記雨樋装置においては、軒樋ａで処理できる水の流量を増やすには、軒樋ａ自体の断面寸法を大きくしたり、呼び樋ｂや竪樋ｃの口径の拡大、本数の増加を図る必要がある。しかし、これらは、コストの上昇、見栄えの低下といった問題がある。   By the way, in the gutter device, in order to increase the flow rate of water that can be treated with the eaves a, the cross-sectional dimension of the eaves a itself is increased, the diameter of the call b or c is increased, and the number of the eaves a is increased. It is necessary to plan. However, these have problems such as an increase in cost and a decrease in appearance.

そこで、口径の拡大や本数を増やすことがなく排水処理量を増加させる雨樋装置として、特許文献１〜２に記載されているようなサイホン式排水システムが提案されている。
即ち、特許文献１には、軒樋の底面に、軒樋よりも小さくかつ竪樋よりも大きな断面寸法を有した凹部状の落し口を設け、この落し口の底面に竪樋を接続したサイホン式排水システムによる雨樋装置が記載されている。
また、特許文献２には、樋状体に設けられた落とし口の上方に、二枚の平行な平板を互いに間隔をおいて配設した屋根取水口が記載されている。
特開平９−１１１９７２号公報（図１） 特表平８−５０６３９６号公報（Ｆｉｇ１） Therefore, siphon-type drainage systems such as those described in Patent Documents 1 and 2 have been proposed as rain gutter devices that increase the amount of drainage without increasing the diameter or number of pipes.
That is, Patent Document 1 provides a siphon in which a recess-shaped drop opening having a cross-sectional dimension smaller than an eave basket and larger than that of the eave basket is provided on the bottom surface of the eave basket, and a hook is connected to the bottom surface of the drop opening. A rain gutter device with a water drainage system is described.
Patent Document 2 describes a roof intake port in which two parallel flat plates are spaced apart from each other above a drop port provided in a bowl-shaped body.
Japanese Patent Laid-Open No. 9-111972 (FIG. 1) Japanese translation of PCT publication No. 8-506396 (FIG. 1)

しかしながら、上記特許文献１〜２に記載された排水方式は、いずれもサイホン式排水システムの構造によるものであるが、特許文献１に記載された雨樋装置にあっては、凹部状の落し口としては大きな深さを有したものでないと効果が期待できない。軒樋の底面に大きな深さを有した凹部状の落し口を設けると、軒樋を下方から見ると大きな落とし口が見えて外観上見栄えがよくない。
また、特許文献２に記載された雨樋装置においては、平板に落ち葉等の塵が引っ掛かり落とし口にゴミ詰まりを発生し易く、塵の除去が煩瑣である。また、落とし口の排水構造が複雑でコストが上昇するという問題点がある。 However, the drainage methods described in Patent Documents 1 and 2 are all based on the structure of the siphon drainage system. However, in the rain gutter device described in Patent Document 1, a recess-shaped drop mouth is used. However, the effect cannot be expected unless it has a great depth. If a recess-shaped drop opening having a large depth is provided on the bottom surface of the eaves bowl, when the eave bowl is viewed from below, a large drop opening is seen and the appearance is not good.
Moreover, in the rain gutter device described in Patent Document 2, dust such as fallen leaves is easily caught on the flat plate, and clogging of dust is likely to occur at the dropping port, and dust removal is troublesome. In addition, there is a problem that the drainage structure of the outlet is complicated and the cost increases.

本発明は、このような事情に鑑みて、低コストで見栄えを低下させることなく排水処理量を増加させることのできる雨樋装置を提供することを目的としている。   In view of such circumstances, an object of the present invention is to provide a rain gutter apparatus that can increase the amount of wastewater treatment at low cost without reducing appearance.

このような目的を達成するために、請求項１に記載の発明に係わる雨樋装置（以下、「請求項１の雨樋装置」と記す）は、軒先に軒樋が配設されており、該軒樋の底壁に排水ドレンが設けられ、この排水ドレンには下方に呼び樋と竪樋がエルボを介してこの順に接続され、竪樋の下端部が地中に埋設された排水管に接続されている雨樋装置において、竪樋の口径が呼び樋の口径よりも小さくされていることを特徴としている。   In order to achieve such an object, the rain gutter apparatus according to the invention described in claim 1 (hereinafter referred to as “the gutter apparatus of claim 1”) is provided with an eave gutter at the eaves, A drainage drain is provided on the bottom wall of the eaves, and a drainage drain is connected to the drainage drain through the elbow and a lower end of the fence is buried in the ground. The connected gutter apparatus is characterized in that the diameter of the gutter is smaller than the diameter of the call gutter.

また、請求項２に記載の発明に係わる雨樋装置（以下、「請求項２の雨樋装置」と記す）は、請求項１の雨樋装置において、呼び樋と竪樋との口径比が１．３〜２．５であることを特徴としている。   Further, the rain gutter apparatus according to the invention of claim 2 (hereinafter referred to as “gutter apparatus of claim 2”) is the gutter apparatus according to claim 1, wherein the aperture ratio between the call gutter and the gutter is It is 1.3 to 2.5.

本発明の雨樋装置によれば、軒先に軒樋が配設されており、該軒樋の底壁部に排水ドレンが設けられ、この排水ドレンには下方に呼び樋と竪樋がこの順に接続され、竪樋の下端部が地中に埋設された排水管に接続されている雨樋装置において、竪樋の径が呼び樋の径よりも小さくされているので、排水ドレンから呼び樋を流下する雨水は竪樋の中を満水状態にして流下することになる。そのため、排水ドレンから呼び樋に流れ込んだ雨水は、呼び樋内でサイホン現象をおこして排水管側に排水され、排水処理量を増加させることができる。   According to the gutter device of the present invention, the eaves are disposed at the eaves, and the drainage drain is provided on the bottom wall of the eaves, and the drainage drain has a callout and a gutter below in this order. In the rain gutter device that is connected and the bottom end of the gutter is connected to a drain pipe buried in the ground, the diameter of the gutter is made smaller than the diameter of the gutter. The rainwater that flows down will flow down with the water filled in the cage. Therefore, rainwater that has flowed from the drainage drain into the sluice causes a siphon phenomenon in the sluice and is drained to the drainage pipe side, thereby increasing the wastewater treatment amount.

次に、本発明の実施の形態の一例を、図に基づいて説明する。   Next, an example of an embodiment of the present invention will be described with reference to the drawings.

図１において、雨樋装置は、家屋の屋根の軒先に軒樋１が取付けられ、この軒樋１の底壁１１に排水ドレン２が設けられ、排水ドレン２には下方にエルボ３を介して呼び樋４の一端が接続され、呼び樋４の他端にエルボ３１を介して竪樋５が接続され、竪樋５の下端が排水管カバー６を介して地中に埋設された排水管７に接続され、屋根ｆの軒先から流下した雨水を受けて排水管７側に排水するようになされている。   In FIG. 1, the gutter apparatus has an eaves 1 attached to the eaves of the roof of a house, a drainage drain 2 is provided on the bottom wall 11 of the eaves 1, and the drainage drain 2 is provided with an elbow 3 below. One end of the call basin 4 is connected, the other end of the call basin 4 is connected to the basin 5 via the elbow 31, and the lower end of the basin 5 is buried in the ground via the drain pipe cover 6. The rainwater flowing down from the eaves of the roof f is received and drained to the drain pipe 7 side.

軒樋１は、押出成形品であり、本体部が平坦な底壁１１の前側部から前側壁１２が立設され、かつ底壁１１の後側部から後側壁１３が立設された溝形断面に形成されており、軒樋１同士が長手方向（図面と直交する方向）に端部を互いに突き合わせた状態で軒樋継手（図示しない）を介して配設され、鼻隠し板９０に取付けられた雨樋吊具８により吊設されて、屋根９の軒先から流下した雨水を受けるようになっている。   The eaves 1 is an extruded product, and has a groove shape in which a front side wall 12 is erected from a front side portion of a bottom wall 11 having a flat main body portion, and a rear side wall 13 is erected from a rear side portion of the bottom wall 11. It is formed in a cross section, and the eaves ridges 1 are arranged via eave ridge joints (not shown) with their ends abutting each other in the longitudinal direction (direction orthogonal to the drawing) and attached to the nose cover plate 90 The rain gutter suspended from the rain gutter suspension 8 is adapted to receive rain water flowing down from the eaves of the roof 9.

排水ドレン２は、取付け鍔板２１の上方に網体２０が突出して形成され、下方に落とし口２２が垂下して設けれており、この落とし口２２が軒樋１の底壁１１に穿口された貫通口１１ａから突設して、下方のエルボ３に回動自在に接続して取付けられるようになっている。   The drainage drain 2 is formed with a net 20 projecting above the mounting gutter plate 21 and provided with a drop port 22 hanging downward, and this drop port 22 is drilled in the bottom wall 11 of the eaves wall 1. It protrudes from the made through-hole 11a, and is connected to the lower elbow 3 so as to be freely rotatable.

呼び樋４は、軒樋１に設けられた排水ドレン２から流下した雨水を水平に導水するもので、一端側がエルボ３に接続され、他端側がエルボ３１にされるようになっている。   The call basin 4 horizontally guides rainwater flowing down from the drainage drain 2 provided in the eaves basin 1, and one end side is connected to the elbow 3 and the other end side thereof is the elbow 31.

竪樋５は呼び樋４から流水される雨水を下方に導水するもので、上端側がエルボ３１に接続され、外壁９１に沿って垂下させて他端が排水管カバー６を介して地中に埋設された排水管７に接続されている。竪樋５の口径ｔが３０ｍｍで、呼び樋４の口径ｙ（６０ｍｍ）よりも小さくされており、その比率は２．０とされている。   The ridge 5 guides rainwater flowing from the basin 4 downward, the upper end side is connected to the elbow 31, hangs down along the outer wall 91, and the other end is buried in the ground via the drain pipe cover 6. The drainage pipe 7 is connected. The diameter t of the collar 5 is 30 mm, which is smaller than the diameter y (60 mm) of the nominal diameter 4, and the ratio thereof is 2.0.

上記の軒樋１と呼び樋４及び竪樋５を使用して雨樋装置を組み立てるには、先ず、軒樋１の底壁１１の排水ドレン２を取り付ける位置に、貫通口１１ａを開口する。続いて、図２に示すように、軒樋１の貫通口１１ａから排水ドレン２の落とし口２２を挿入して下方に突出させ、下方に突出した落とし口２２に接続部材２３で螺合し、排水ドレン２の取付け鍔片２１と接続部材２３の鍔片２４とで、軒樋１の貫通口１１ａの周縁をパッキン等を介在させて挟着固定する。   In order to assemble the rain gutter apparatus using the eaves ridge 1 and the call ledges 4 and 5, first, the through-hole 11 a is opened at a position where the drainage drain 2 of the bottom wall 11 of the eave ridge 1 is attached. Subsequently, as shown in FIG. 2, the outlet 22 of the drainage drain 2 is inserted from the through hole 11 a of the eaves 1 and protruded downward, and is screwed into the outlet 22 protruding downward by the connecting member 23. The peripheral edge of the through-hole 11a of the eaves rod 1 is clamped and fixed with a packing or the like between the attachment rod piece 21 of the drainage drain 2 and the flange piece 24 of the connecting member 23.

次に、軒先の鼻隠し板９０に雨樋吊具８の取付部８１をネジ等の固定具により取付けてから、軒樋吊具８の前耳保持部８２に軒樋１の前耳１４を係止させ、後耳保持部８３に軒樋１の後耳１５を挿入して係止させる。   Next, after attaching the attachment part 81 of the rain gutter suspension 8 to the eaves nose cover plate 90 with a fixing tool such as a screw, the front ear 14 of the eaves enclosure 1 is attached to the front ear holding part 82 of the eaves suspension hanger 8. The rear ear 15 of the eaves rod 1 is inserted into the rear ear holding portion 83 and locked.

最後に、軒樋１を軒樋継手（図示しない）で接続してから、排水ドレン２の落とし口２２にエルボ３を取付け、このエルボ３に呼び樋４を接続し、エルボ３１を介して竪樋５を接続し、竪樋１の下端に排水管カバー６を取付けてから排水管７と接続する。   Finally, after connecting the eaves 1 with an eaves joint (not shown), the elbow 3 is attached to the outlet 22 of the drainage drain 2, the call bar 4 is connected to the elbow 3, and the elbow 31 is connected via the elbow 31. The tub 5 is connected, and the drain pipe cover 6 is attached to the lower end of the tub 1 and then connected to the drain pipe 7.

屋根に降った雨は軒樋１に設けられた排水ドレン２から呼び樋４を流れて竪樋５に流下する。竪樋５の口径ｔが呼び樋４の口径ｙよりも細いため、呼び樋４から竪樋５に流れ込んた雨水は竪樋４の中を満水状態にして流下することになり、落とし口２２と呼び樋４内でサイホン現象をおこして、竪樋５から排水管７側に勢いよく排水されることになる。   The rain that falls on the roof flows from the drainage drain 2 provided on the eaves 1 to the side 4 and then to the side 5. Since the diameter t of the reed 5 is thinner than the diameter y of the reed 4, rainwater flowing from the reed 4 to the reed 5 flows down in a full state in the reed 4. A siphon phenomenon occurs in the call basin 4 and the water is drained vigorously from the basin 5 to the drain pipe 7 side.

以上、本発明実施例を図面に基づいて説明してきたが、具体的な構成はこの実施例に限られるものではなく本発明の要旨を逸脱しない範囲の設計変更等があっても本発明に含まれる。例えば、呼び樋４を水平に配設したが、斜め下向きに傾斜させてもよい。   As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to the embodiments, and design changes and the like within the scope of the present invention are included in the present invention. It is. For example, the call 4 is disposed horizontally, but may be inclined obliquely downward.
