本発明は竪樋の中間部から雨水を取出す雨水取出部の構造に関し、詳しくは、雨水中の落葉等で目詰まりしない雨水取出部の構造の技術に関する。   The present invention relates to a structure of a rainwater extraction portion that extracts rainwater from an intermediate portion of a kite, and more particularly to a technique of a structure of a rainwater extraction portion that is not clogged with fallen leaves in rainwater.

植物の潅水等に雨水を利用するための雨水取出部の構造に関する従来技術として特許文献１に掲載の内容が知られている。図６に示すように、建物の屋根１１１に取付けられた軒樋１１２に竪樋１１４が連結され、竪樋１１４の中間適所に雨水取出部１０２が設けられる。雨水取出部１０２の受水面１２１に臨んでいる受水口１２２と、雨水貯水槽１０３内の接続管１４１とを給水管１４０で連通する。接続管１４１は雨水貯水槽１０３内部で上下に貫通しており、その上端は通気孔１４２として貯水面１３１より突出し、下端は雨水貯水槽１０３の底板１３２に向かって開口する給水口１４３である。   The contents described in Patent Document 1 are known as a conventional technique relating to the structure of a rainwater extraction portion for using rainwater for irrigation of plants and the like. As shown in FIG. 6, a ridge 114 is connected to an eaves ridge 112 attached to the roof 111 of the building, and a rainwater extraction portion 102 is provided at an appropriate intermediate position of the ridge 114. The water receiving port 122 facing the water receiving surface 121 of the rainwater extraction unit 102 and the connection pipe 141 in the rainwater storage tank 103 are communicated with each other through a water supply pipe 140. The connecting pipe 141 penetrates vertically inside the rainwater storage tank 103, and the upper end thereof protrudes from the water storage surface 131 as a vent hole 142, and the lower end is a water supply port 143 that opens toward the bottom plate 132 of the rainwater storage tank 103.

給水口１４３よりも高い位置に取水口１３３を設け、その先端に止水栓１３４を装着する。また、雨水貯水槽１０３の底板１３２と取水口１３３の高さ位置との間を沈殿部１０５とし、給水口１４３から吐出されるホコリ、汚泥等の沈殿物が底板１３２上面に堆積される。一方、雨水貯水槽１０３の上部は、貯水面１３１を形成する位置に雨水の排水口１４４を開口させ、排水口１４４を介して雨水貯水槽１０３の外部へ排水管１４５を接続し、その先端を貯水の余水が流下するよう竪樋１１４の下方位置に連通する。

Further, the precipitation portion 105 is formed between the bottom plate 132 of the rainwater storage tank 103 and the height position of the water intake port 133, and deposits such as dust and sludge discharged from the water supply port 143 are accumulated on the upper surface of the bottom plate 132. On the other hand, the upper part of the rainwater storage tank 103 is opened with a rainwater drainage 144 at a position where the water storage surface 131 is formed, and the drainage pipe 145 is connected to the outside of the rainwater storage tank 103 via the drainage outlet 144, It communicates with the lower position of the trough 114 so that the remaining water of the stored water flows down.
Registered Utility Model No. 3098271

ところが、雨水取出部１０２において、雨水と共に流れる落葉、泥、ゴミ等によって受水口１２２が塞がるという問題があった。この問題を解決する手段として、図７に示すように、受水面１２１を下方の竪樋１１４に向けて斜めに傾斜させ、その傾斜面の下流側に給水管１４０の受水口１２２を設け、傾斜する受水面１２１にフイルタ−１２５を設ける方法がある。   However, there is a problem in the rainwater extraction section 102 that the water receiving port 122 is blocked by fallen leaves, mud, dust, and the like flowing along with the rainwater. As a means for solving this problem, as shown in FIG. 7, the water receiving surface 121 is inclined obliquely toward the lower ridge 114, and the water receiving port 122 of the water supply pipe 140 is provided on the downstream side of the inclined surface. There is a method of providing a filter-125 on the water receiving surface 121.

しかし、受水面１２１に傾斜を設けても、雨水中の落葉、ゴミ等の蓄積を完全に防止することは困難で、時々フイルタ−１２５の掃除や取替えが必要となるため、作業に手間取り効率が悪く、安定して必要量の雨水を雨水貯水槽１０３に集水することが困難であった。   However, even if the water receiving surface 121 is inclined, it is difficult to completely prevent the accumulation of fallen leaves and dust in rainwater, and it is sometimes necessary to clean or replace the filter-125. Unfortunately, it was difficult to stably collect the necessary amount of rainwater in the rainwater storage tank 103.

そこで、本発明はかかる従来技術の問題に鑑みなされたものであって、雨水中の落葉、ゴミ等が蓄積せず、雨水を確実に竪樋から集水できる雨水取出部の構造の技術を提供することを目的とする。   Accordingly, the present invention has been made in view of the problems of the prior art, and provides a technology for a structure of a rainwater extraction part that can collect rainwater reliably from rainwater without accumulating defoliation and dust in rainwater.

＜本発明の第１の実施形態＞
以下に、本発明の第１の実施形態を図１〜図３に基づいて説明する。
＜雨水取出部の構造の構成＞ <First Embodiment of the Present Invention>
Below, the 1st Embodiment of this invention is described based on FIGS. 1-3.
<Structure of rainwater outlet>

図１、図２、図３に示すように、本発明の竪樋１に装着される雨水取出部２は本体部３と突出部４で形成される。いま、図示しない建物の屋根から円筒状の竪樋１が垂下され、この竪樋１の中間部で竪樋１の一部を切欠き、この切欠かれた後の竪樋１の上端部１ａと下端部１ｂを覆うように本体部３を取付け、本体部３に連結して突出部４が竪樋１から突出する。   As shown in FIG. 1, FIG. 2, and FIG. 3, the rainwater extraction portion 2 attached to the bag 1 of the present invention is formed by a main body portion 3 and a protruding portion 4. Now, a cylindrical fence 1 is suspended from the roof of a building (not shown), a part of the fence 1 is cut out at the middle portion of the fence 1, and the upper end 1a of the fence 1 after the notch is cut off. The main body portion 3 is attached so as to cover the lower end portion 1b, and the protrusion portion 4 protrudes from the flange 1 in connection with the main body portion 3.

より詳しくは、雨水取出部２の本体部３の外廓は、竪樋１の切欠かれたθ＝略１８０度の半割り領域を竪樋１の上端部１ａと下端部１ｂに沿って覆う形状である。突出部４の外郭は、竪樋１の残りの半割り領域を包含するとともに竪樋１から突出し、垂直状の側面４ａが頂面４ｂと底面４ｃで覆われ、平面視で側面４ａが略放物線を描く様に形成される。そして、頂面４ｂに水切り用の傾斜が竪樋１から離れる方向に下り勾配で設けられ、水平状の底面４ｃに雨水取出管５を備え、突出部４内にフィルター６が内装される。   More specifically, the outer casing of the main body 3 of the rainwater extraction section 2 has a shape that covers the half-divided region of θ = approximately 180 degrees of the kite 1 along the upper end 1a and the lower end 1b of the kite 1. It is. The outline of the protrusion 4 includes the remaining half of the ridge 1 and protrudes from the ridge 1, the vertical side surface 4a is covered with the top surface 4b and the bottom surface 4c, and the side surface 4a is substantially parabolic in plan view. It is formed to draw. The top surface 4b is provided with a slope for draining in a direction away from the eaves 1 with a downward slope. The horizontal bottom surface 4c is provided with a rainwater take-out pipe 5, and a filter 6 is provided in the protruding portion 4.

このように、雨水取出部２の外廓形状としては、本体部３の外廓は竪樋１の半割り領域だけを覆っているが、本体部３は実質的に竪樋１の切欠かれた領域を囲む円筒領域である。   Thus, as for the shape of the outer casing of the rainwater extraction part 2, the outer casing of the main body 3 covers only the half area of the main casing 1, but the main body 3 is substantially cut away from the main casing 1. A cylindrical region surrounding the region.

竪樋１の下端部１ｂには下端部１ｂから上方に突設する第一円筒スリーブ７が形成される。第一円筒スリーブ７の外径Ｓは竪樋１の内径Ｓ１より小さく、第一円筒スリーブ７と竪樋１の内面１ｃとの間の環状隙間Ｇに第二円筒スリーブ８が挿入される。第二円筒スリーブ８の上端面８ａと竪樋１の下端部１ｂとは面一に形成される。   A first cylindrical sleeve 7 projecting upward from the lower end 1b is formed at the lower end 1b of the flange 1. The outer diameter S of the first cylindrical sleeve 7 is smaller than the inner diameter S1 of the flange 1, and the second cylindrical sleeve 8 is inserted into the annular gap G between the first cylindrical sleeve 7 and the inner surface 1c of the flange 1. The upper end surface 8a of the second cylindrical sleeve 8 and the lower end portion 1b of the flange 1 are formed flush with each other.

そして、本体部３内に落葉詰まり防止具１０を備える。落葉詰まり防止具１０は、連続的に縮径する側面視台形状の円形筒状体１１と、その円形筒状体１１の上部の大径部１１ａに竪樋１の内径Ｓ１と同じ大きさの内径Ｓ１で上筒部１２が連結された形状である。円形筒状体１１には複数の開口部Ｈが網目状に形成される。落葉詰まり防止具１０は下部の小径部１１ｂを第一円筒スリーブ７に若干挿入した状態で、上筒部１２が上端部１ａと内面面一に当接して装着される。   And the fallen leaf clogging prevention tool 10 is provided in the main body 3. The fallen leaf clog prevention device 10 has a circular cylindrical body 11 having a trapezoidal side view that continuously reduces in diameter, and a large diameter portion 11a at the top of the circular cylindrical body 11 having the same size as the inner diameter S1 of the ridge 1. It is the shape where the upper cylinder part 12 was connected by the internal diameter S1. The circular cylindrical body 11 is formed with a plurality of openings H in a mesh shape. The fallen leaf clogging prevention device 10 is mounted in a state where the lower small diameter portion 11b is slightly inserted into the first cylindrical sleeve 7 so that the upper cylindrical portion 12 is in contact with the upper end portion 1a and the inner surface.

雨水取出部２の本体部３と突出部４は図示しない固定具で開閉自在に連結され、落葉詰まり防止具１０を装着した後、本体部３と突出部４は固定具で一体的に連結される。落葉詰まり防止具１０の装着方法は、まず、第一円筒スリーブ７を下げた状態で落葉詰まり防止具１０を所定位置に挿入したのち、第一円筒スリーブ７を持上げて第二円筒スリーブ８に固着することで装着できる。そして、突出部４を開けることでフィルター６は容易に保守点検、清掃、交換ができる。落葉詰まり防止具１０はメンテナンスフリーで必要時に応じて突出部４を開けてノズル等を用いて水洗い清掃することができる。   The main body part 3 and the projecting part 4 of the rainwater extraction part 2 are connected to each other by a fixing tool (not shown) so as to be opened and closed. After the fallen leaf clogging prevention tool 10 is mounted, the main body part 3 and the projecting part 4 are integrally connected by the fixing tool. The The method for mounting the fallen leaf clogging prevention device 10 is as follows. First, the fallen leaf clogging prevention device 10 is inserted into a predetermined position with the first cylindrical sleeve 7 lowered, and then the first cylindrical sleeve 7 is lifted and fixed to the second cylindrical sleeve 8. Can be installed. The filter 6 can be easily inspected, cleaned, and replaced by opening the protrusion 4. The fallen leaf clog prevention device 10 is maintenance-free and can be washed with water using a nozzle or the like by opening the protrusion 4 as needed.

＜雨水取出部の構造の作用＞
図２に示すように、通常、竪樋１内を流れる雨水Ｐの殆どは自由落下ではなく竪樋１の内面１ｃに沿って流れる。ここで、竪樋１の内径Ｓ１と落葉詰まり防止具１０の上筒部１２の内径Ｓ１が同じなので、雨水Ｐは竪樋１の上端部１ａにおいて落葉詰まり防止具１０の上筒部１２の内面に沿ってスムーズに流下する。そして、雨水Ｐは連続的に縮径する円形筒状体１１に沿って流れる途中で、円形筒状体１１に形成される複数の網目状の開口部Ｈを抜けて雨水Ｐは落下する。 <Operation of the structure of the rainwater outlet>
As shown in FIG. 2, most of the rainwater P flowing through the ridge 1 normally flows along the inner surface 1 c of the ridge 1 rather than free fall. Here, since the inner diameter S1 of the heel 1 and the inner diameter S1 of the upper cylinder portion 12 of the fallen leaf clogging prevention device 10 are the same, the rain water P is the inner surface of the upper cylinder portion 12 of the fallen leaf clogging prevention device 10 at the upper end portion 1a of the heel 1. It flows down smoothly along. The rainwater P falls through the plurality of mesh-shaped openings H formed in the circular cylindrical body 11 while the rainwater P flows along the circular cylindrical body 11 continuously reducing in diameter.

第一円筒スリーブ７と竪樋１の内面１ｃとの間に第二円筒スリーブ８が挿入されているので、竪樋１の内面１ｃの全周に張出したこの第二円筒スリーブ８の上端面８ａと竪樋１の下端部１ｂの全周領域に落下する雨水Ｐを受けることができる。そして、雨水Ｐは第一円筒スリーブ７によって竪樋１に戻ることなく竪樋１の下端部１ｂを経て突出部４に流入し、雨水Ｐはフィルター６を通って雨水取出管５から取出され図示しない貯水槽に導かれる。なお、豪雨時には過剰の雨水は第一円筒スリーブ７の内部を流れて竪樋１に流出する。   Since the second cylindrical sleeve 8 is inserted between the first cylindrical sleeve 7 and the inner surface 1c of the flange 1, the upper end surface 8a of the second cylindrical sleeve 8 protruding over the entire circumference of the inner surface 1c of the flange 1 is provided. The rainwater P falling on the entire peripheral area of the lower end 1b of the trough 1 can be received. Then, the rainwater P flows into the projecting portion 4 through the lower end 1b of the rod 1 without returning to the rod 1 by the first cylindrical sleeve 7, and the rainwater P is taken out from the rainwater take-out pipe 5 through the filter 6. Not led to the water tank. In the case of heavy rain, excessive rainwater flows through the first cylindrical sleeve 7 and flows out to the kite 1.

このように、落葉詰まり防止具１０において、雨水Ｐは網目状の開口部Ｈから自然流下するが、落葉やゴミ等は網目状の開口部Ｈを通過できないので、突出部４に流入することなく円形筒状体１１に沿って落下して下方の竪樋１に流れる。なお、竪樋１の図示しない最上端には落葉やゴミ等の流下防止用ドレンが設けられるで、大きな落葉やゴミ等は予め竪樋１に流れないので、落葉詰まり防止具１０より下方に流れる落葉やゴミ等は詰まることなく排出される。このように、落葉詰まり防止具１０は取水機能が低下せずメンテナンスフリーである。   As described above, in the fallen leaf clogging prevention device 10, the rainwater P naturally flows from the mesh-shaped opening H, but since fallen leaves and dust cannot pass through the mesh-shaped opening H, the rainwater P does not flow into the protrusion 4. It falls along the circular cylindrical body 11 and flows to the lower cage 1. In addition, since a drain for preventing the fall of leaves, dust, etc. is provided at the uppermost end (not shown) of the basket 1, large leaves, dust, etc. do not flow into the basket 1 in advance, and therefore flow downward from the fallen clogging prevention device 10. Fallen leaves and garbage are discharged without clogging. Thus, the fallen leaf clog prevention device 10 is maintenance-free without reducing the water intake function.

＜本発明の第２の実施形態＞
以下に、本発明の第２の実施形態を説明するが、図３と同構成部分については、図面に同符号を付して重複した説明を省略する。 <Second Embodiment of the Present Invention>
Hereinafter, a second embodiment of the present invention will be described, but the same components as those in FIG.

図４に示すように、円形筒状体１１の開口部Ｈ１は円形筒状体１１に沿って放射線状に形成されるので、雨水はさらに容易且つ確実に開口部Ｈ１を通過することができるので連続的に安定して雨水を取出すことができる。   As shown in FIG. 4, since the opening H1 of the circular cylindrical body 11 is formed radially along the circular cylindrical body 11, rainwater can pass through the opening H1 more easily and reliably. Rain water can be taken out continuously and stably.

＜本発明の第３の実施形態＞
以下に、本発明の第３の実施形態を説明するが、図３と同構成部分については、図面に同符号を付して重複した説明を省略する。 <Third Embodiment of the Present Invention>
In the following, a third embodiment of the present invention will be described. However, the same components as those in FIG.

図５に示すように、上筒部１２の下端部が内面１２ａから外面１２ｂに亘って弧状１２ｃに形成されるので、竪樋１の内面を伝って下降する雨水Ｐが弧状１２ｃを伝って容易且つ確実に突出部４側に流れるのでさらに確実に取水量が確保できる。   As shown in FIG. 5, since the lower end portion of the upper cylinder portion 12 is formed in an arc shape 12c from the inner surface 12a to the outer surface 12b, the rainwater P descending along the inner surface of the ridge 1 can easily travel along the arc shape 12c. And since it flows to the protrusion part 4 side reliably, a water intake amount can be ensured more reliably.

以上、本発明の実施例を図面に基づいて説明したが、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、竪樋１の形状は矩形筒状でも構わず、その矩形断面形状に対応して雨水取出部２の構造が決定される。落葉詰まり防止具１０の下部の小径部１１ｂを第一円筒スリーブ７の直径と同じにして第一円筒スリーブ７の上端部に当接する状態でも構わない。落葉詰まり防止具１０は上筒部１２を省いて、円形筒状体１１の上部の大径部１１ａを直接竪樋１に当接してもよい。上筒部１２の下端部に内面１２ａから外面１２ｂに亘って形成される弧状１２ｃは放射線状の開口部Ｈ１を備える円形筒状体１１に適用しても構わない。落葉詰まり防止具を着脱式に構成しても構わない。   The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope of the present invention are included in the present invention. It is. For example, the shape of the ridge 1 may be a rectangular cylinder, and the structure of the rainwater extraction portion 2 is determined corresponding to the rectangular cross-sectional shape. The lower diameter portion 11b of the lower part of the fallen leaf clogging prevention device 10 may be the same as the diameter of the first cylindrical sleeve 7 and may be in contact with the upper end portion of the first cylindrical sleeve 7. The fallen leaf clogging prevention device 10 may omit the upper tube portion 12 and directly contact the large diameter portion 11a of the upper portion of the circular tubular body 11 to the ridge 1. The arc shape 12c formed on the lower end portion of the upper cylindrical portion 12 from the inner surface 12a to the outer surface 12b may be applied to the circular cylindrical body 11 having the radial opening H1. The fallen leaf clog prevention tool may be configured to be detachable.
