Further, the lower end portion of the opening 805 of the filter unit 80 is wider in the left-right width than the upper portion, and the front end portion of the lower plate portion 51 is fitted into this portion. Thus, the movement of the filter member 8 in the left-right direction with respect to the water passage member 5 is restricted. That is, the peripheral edge portion of the opening 805 of the filter member 8 constitutes a positioning portion for determining the position of the filter member 8 with respect to the water passage member 5. The positioning portion is not limited to the peripheral portion of the opening 805 of the filter member 8.

図３に示されるように、フィルター部材８の両側の側面部８０３の後端面は、夫々、壁沿部８０７を構成している。各壁沿部８０７は、側面部８０３の後端部において後側に突出した上下複数の横片部８０６の突出端面で構成されている。   As shown in FIG. 3, the rear end surfaces of the side surface portions 803 on both sides of the filter member 8 constitute wall side portions 807, respectively. Each wall side portion 807 is configured by protruding end surfaces of a plurality of upper and lower horizontal piece portions 806 protruding rearward at the rear end portion of the side surface portion 803.

両壁沿部８０７は軒樋２の長手方向である左右方向において離間して位置しており、図１に示されるように左右方向において落とし口２００を挟んだ両側に配置されている。フィルター部材８において、両壁沿部８０７の中間部分に位置するフィルター部８０（すなわち、前面部８０２及び両側面部８０３）は、軒樋２の後壁部２２と反対側となる前側に向かって張り出している。   Both wall side portions 807 are spaced apart in the left-right direction, which is the longitudinal direction of the eaves 2, and are disposed on both sides of the pit 200 in the left-right direction as shown in FIG. 1. In the filter member 8, the filter portion 80 (that is, the front surface portion 802 and the both side surface portions 803) located at the intermediate portion between both wall side portions 807 protrudes toward the front side opposite to the rear wall portion 22 of the eaves wall 2. ing.

フィルター部材８の両側の壁沿部８０７は、軒樋２の後壁部２２の前面に沿って配置され、後壁部２２に対向している。このため、フィルター部材８の後方への移動は、軒樋２によって規制されている。なお、フィルター部材８の両側の壁沿部８０７は、軒樋２の後壁部２２の前面に接触してもよいし、非接触で軒樋２の後壁部２２の前面近傍に配置されてもよい。   The wall side portions 807 on both sides of the filter member 8 are arranged along the front surface of the rear wall portion 22 of the eaves 2 and face the rear wall portion 22. For this reason, the backward movement of the filter member 8 is restricted by the eaves 2. The side walls 807 on both sides of the filter member 8 may be in contact with the front surface of the rear wall portion 22 of the eaves 2 or arranged in the vicinity of the front surface of the rear wall portion 22 of the eaves 2 without contact. Also good.

フィルター部８０の両側の側面部８０３の後端部を構成する上下複数の横片部８０６のうち、上端部に位置する２つの横片部８０６の間には、軒樋２の後耳部２２０が配置されている。これにより、フィルター部材８が上方に移動したときには、後耳部２２０の下方に配置された横片部８０６が後耳部２２０に当たってフィルター部材８の上方への移動が規制される。   Among the plurality of upper and lower horizontal piece portions 806 constituting the rear end portion of the side surface portion 803 on both sides of the filter portion 80, the rear ear portion 220 between the two horizontal piece portions 806 located at the upper end portion is provided. Is arranged. As a result, when the filter member 8 moves upward, the horizontal piece 806 disposed below the rear ear portion 220 hits the rear ear portion 220 and the upward movement of the filter member 8 is restricted.

突部８１はフィルター部８０の上面部を構成する天井部８０１から前方に向かって突出している。突部８１は、左右に長い係止部８１０と、係止部８１０から後方に突出した複数の接続片部８１１を備えている。各接続片部８１１の後端部は、天井部８０１に繋がれている。係止部８１０の前面には、側断面三角形状の係止溝部８１２が形成されている。   The protruding portion 81 protrudes forward from the ceiling portion 801 constituting the upper surface portion of the filter portion 80. The protrusion 81 includes a locking portion 810 that is long on the left and right, and a plurality of connection piece portions 811 that protrude rearward from the locking portion 810. A rear end portion of each connection piece portion 811 is connected to the ceiling portion 801. A locking groove portion 812 having a triangular side cross section is formed on the front surface of the locking portion 810.

係止部８１０は、係止溝部８１２に軒樋２の前耳部２１０に嵌め込むことで、軒樋２に着脱可能に係止されている。これにより、軒樋２によってフィルター部材８の前端部の上下両方向及び前方への移動が規制されている。   The locking part 810 is detachably locked to the eaves bowl 2 by fitting the locking groove part 812 into the front ear part 210 of the eaves bowl 2. Thereby, the movement of the front end portion of the filter member 8 in both the vertical direction and the forward direction is restricted by the eaves rod 2.

つまり、フィルター部材８は、開口部８０５に通水部材５を嵌め込み、両壁沿部８０７を軒樋２の後壁部２２に沿わせ、突部８１の係止部８１０を軒樋２の前耳部２１０に係止することで、軒樋２及びこれに取り付けられた通水部材５の両者に固定されている。   In other words, the filter member 8 has the water passage member 5 fitted in the opening 805, the both wall side portions 807 are along the rear wall portion 22 of the eaves 2, and the locking portion 810 of the protrusion 81 is located in front of the eaves 2. By being locked to the ear portion 210, it is fixed to both the eaves 2 and the water-permeable member 5 attached thereto.

そして、フィルター部材８において、両壁沿部８０７の中間部分に位置するフィルター部８０と、軒樋２の後壁部２２とによって、軒樋２の落とし口２００の上方空間１０が囲まれており、この空間１０に通水部材５及びねじ部材６が配置されている。   In the filter member 8, the upper space 10 of the drop port 200 of the eaves 2 is surrounded by the filter 80 located in the middle portion between the both side walls 807 and the rear wall 22 of the eaves 2. The water passage member 5 and the screw member 6 are disposed in the space 10.

フィルター部材８は、ねじ部材６を突出部材４に螺合して排水筒３及び通水部材５を軒樋２に取り付けた状態のまま、通水部材５及び軒樋２から取り外すことができる。フィルター部材８を取り外すには、係止部８１０を前耳部２１０から外してフィルター部材８を上方に引き上げ、開口部８０５から通水部材５を外せばよい。   The filter member 8 can be detached from the water flow member 5 and the eaves rod 2 while the screw member 6 is screwed to the protruding member 4 and the drain tube 3 and the water flow member 5 are attached to the eaves wall 2. In order to remove the filter member 8, the locking portion 810 is removed from the front ear portion 210, the filter member 8 is pulled upward, and the water passage member 5 is removed from the opening 805.

図２に示される排水筒３の連結部３００には、例えば呼び樋の上流側端部が直接連結される。排水筒３は、その軸方向を鉛直方向に対して傾けた状態で、軒樋２に取り付けられている。このため、軒樋２に呼び樋を連結するためのエルボー等の管材を省略することができる。また、このようにエルボー等の管材を省略した場合、シンプルな外観を有する排水構造にすることができる。なお、呼び樋の下流側端部は、エルボーを介して竪樋の上端部に連結される。   For example, the upstream end portion of the call is directly connected to the connecting portion 300 of the drain tube 3 shown in FIG. The drain tube 3 is attached to the eaves wall 2 with its axial direction inclined with respect to the vertical direction. For this reason, pipe materials, such as an elbow, for connecting the call to the eaves 2 can be omitted. Moreover, when pipe materials, such as an elbow, are abbreviate | omitted in this way, it can be set as the drainage structure which has a simple external appearance. The downstream end portion of the call is connected to the upper end portion of the basket through an elbow.

ドレン１が軒樋２に取り付けられた状態では、軒樋２を流れる雨水は、フィルター部材８の壁部８００の通水孔８０４を通過する。この雨水は、通水部材５の両連結部５２，５３の間、及び下側の挿通孔５１０を順に通って、軒樋２の落とし口２００から排水筒３に流れ込み、呼び樋及び竪樋を介して排出される。   In a state where the drain 1 is attached to the eaves 2, the rainwater flowing through the eaves 2 passes through the water holes 804 of the wall portion 800 of the filter member 8. This rainwater passes between the connecting portions 52 and 53 of the water passage member 5 and the lower insertion hole 510 in order, and then flows into the drain tube 3 from the outlet 200 of the eaves wall 2, so Is discharged through.

軒樋２を流れる雨水がフィルター部材８の通水孔８０４を通過するときには、フィルター部材８の網状のフィルター部８０によって雨水に含まれる落ち葉等のごみが捕集される。このため、通水部材５よりも下流側の排水筒３や、排水筒３の下流側に配置された管材においては、ごみ等が詰まり難くなる。   When rainwater flowing through the eaves 2 passes through the water passage hole 804 of the filter member 8, dust such as fallen leaves contained in the rainwater is collected by the net-like filter portion 80 of the filter member 8. For this reason, in the drain tube 3 downstream of the water flow member 5 and the pipe material disposed on the downstream side of the drain tube 3, dust and the like are hardly clogged.

以上説明した本実施形態のドレン１は、排水筒３、通水部材５、及びフィルター部材８を備えている。排水筒３は、軒樋２の下側に配置されて軒樋２の底部２０に形成された落とし口２００に連通する。通水部材５は、通水性を有し、軒樋２の底部２０上に配置され、排水筒３に対して固定されて軒樋２の底部２０を排水筒３との間に挟み込む。フィルター部材８は、軒樋２の底部２０上に配置されて通水部材５に位置決めされ、ごみを捕集する。フィルター部材８が排水筒３に固定された通水部材５に対して着脱可能に構成される。   The drain 1 of the present embodiment described above includes the drain tube 3, the water passage member 5, and the filter member 8. The drain tube 3 is arranged on the lower side of the eaves wall 2 and communicates with a pit 200 formed in the bottom portion 20 of the eaves wall 2.

フィルター部材８は、左右に離間した側面部８２と、両側面部８２の上端部同士を繋ぐ上面部８３とで構成されている。図４に示されるように、フィルター部材８の左右の側面部８２は、通水部材５の左右両側に配置されている。各側面部８２は左右方向から見て軒樋２の内面に合致する半円状に形成されている。   The filter member 8 includes a side surface portion 82 that is separated from the left and right sides, and an upper surface portion 83 that connects upper end portions of both side surface portions 82. As shown in FIG. 4, the left and right side portions 82 of the filter member 8 are disposed on both the left and right sides of the water passage member 5. Each side surface portion 82 is formed in a semicircular shape that matches the inner surface of the eaves 2 as viewed from the left-right direction.

フィルター部材８の各側面部８２は、軒樋２の底部２３上に載置されている。各側面部８２の円弧状の下面は、軒樋２の内面の周方向の全体に亘って接触している。これによりフィルター部材８の前後方向及び下方への移動が規制されている。また、フィルター部材８の各側面部８２は、左右方向から見たときに、軒樋２の内側に形成される空間の全体（雨水が流れる領域）に亘って配置され、通水部材５の左右両側を覆っている。   Each side surface portion 82 of the filter member 8 is placed on the bottom portion 23 of the eaves 2. The arc-shaped lower surface of each side surface 82 is in contact with the entire inner surface of the eaves 2 in the circumferential direction. This restricts the movement of the filter member 8 in the front-rear direction and in the downward direction. Further, each side portion 82 of the filter member 8 is disposed over the entire space (region where rainwater flows) formed inside the eaves bowl 2 when viewed from the left-right direction, and Covers both sides.

図６に示されるように、フィルター部材８の上面部の中央部には、上下に貫通する嵌込孔８３０が形成されている。嵌込孔８３０は平面視円形の孔であって、その直径はねじ部材６の外径よりも僅かに大きい。   As shown in FIG. 6, a fitting hole 830 penetrating vertically is formed at the center of the upper surface of the filter member 8. The fitting hole 830 is a circular hole in plan view, and its diameter is slightly larger than the outer diameter of the screw member 6.

図５に示されるように、フィルター部材８の嵌込孔８３０には、突出部材４に螺合されたねじ部材６が嵌め込まれている。これによりフィルター部材８の通水部材５に対する水平方向の移動が規制されている。   As shown in FIG. 5, the screw member 6 screwed into the protruding member 4 is fitted into the fitting hole 830 of the filter member 8. Thereby, the horizontal movement of the filter member 8 with respect to the water passage member 5 is restricted.

すなわち、フィルター部材８は、両側の側面部８２を軒樋２の底部２３上に載置して軒樋２の内側に嵌め込み、嵌込孔８３０にねじ部材６を嵌め込むことで、軒樋２及びこれに取り付けられた通水部材５の両者に対して固定されている。   That is, the filter member 8 is configured such that the side portions 82 on both sides are placed on the bottom 23 of the eaves 2 and fitted inside the eaves 2, and the screw member 6 is fitted into the fitting hole 830, thereby And it fixes with respect to both of the water flow members 5 attached to this.

フィルター部材８と軒樋２により、軒樋２の落とし口２００の上方空間１１が囲まれており、この空間１１には通水部材５が配置されている。   The filter member 8 and the eaves 2 surround the upper space 11 of the pit 200 of the eaves 2, and the water flow member 5 is disposed in the space 11.

軒樋２及び通水部材５に対して固定されたフィルター部材８は、フィルター部材８を上方に持ち上げて、ねじ部材６を嵌込孔８３０から外し且つ両側の側面部８２を軒樋２から外すことで、簡単に取り外すことができる。   The filter member 8 fixed to the eaves bowl 2 and the water passage member 5 lifts the filter member 8 upward to remove the screw member 6 from the fitting hole 830 and remove the side portions 82 on both sides from the eave bowl 2. It can be easily removed.

図４に示されるようにドレン１が軒樋２に取り付けられた状態では、軒樋２を流れる雨水は、フィルター部材８の側面部８２の通水孔８４を通過する。この雨水は、通水部材５の両連結部５７，５８の間、及び下側の挿通孔５６０を順に通り、軒樋２の落とし口２００から排水筒３に排出される。ここで、軒樋２を流れる雨水がフィルター部材８の通水孔８４を通過するときには、フィルター部材８の網状の側面部８２によって雨水に含まれる落ち葉等のごみが捕集される。   As shown in FIG. 4, in a state where the drain 1 is attached to the eave cage 2, rainwater flowing through the eave cage 2 passes through the water passage holes 84 of the side surface portion 82 of the filter member 8. The rainwater passes through the connecting portions 57 and 58 of the water passage member 5 and the lower insertion hole 560 in order, and is discharged from the outlet 200 of the eaves 2 to the drain tube 3. Here, when rainwater flowing through the eaves 2 passes through the water passage hole 84 of the filter member 8, dust such as fallen leaves contained in the rainwater is collected by the net-like side surface portion 82 of the filter member 8.

本実施形態の軒樋２の排水構造にあっても、排水筒３とこれに固定された通水部材５とで軒樋２の底部２０を挟み込み、排水筒３及び通水部材５を軒樋２に取り付けた状態のまま、フィルター部材８を通水部材５から取り外すことができる。従って、フィルター部材８で捕集したごみを取り除く作業を、排水筒３及び通水部材５を軒樋２に取り付けた状態のまま、フィルター部材８を取り外して、簡単に行うことができる。   Even in the drainage structure of the eaves bowl 2 according to the present embodiment, the bottom 20 of the eaves bowl 2 is sandwiched between the drainage cylinder 3 and the water passage member 5 fixed to the drainage cylinder 3, and the drainage cylinder 3 and the water passage member 5 are attached to the eaves bowl. The filter member 8 can be removed from the water member 5 while being attached to the water member 2. Therefore, the operation of removing the dust collected by the filter member 8 can be easily performed by removing the filter member 8 while the drain tube 3 and the water passage member 5 are attached to the eaves 2.

なお、第１実施形態及び第２実施形態では、排水筒３の軸方向が軒樋２の底部２０と垂直な方向に対して傾斜しているが、平行であってもよい。また、第１実施形態及び第２実施形態において、排水筒３に連結される下流側の管材は、呼び樋に限られず、エルボー等の継手や竪樋であってもよい。また、第１実施形態及び第２実施形態における通水部材５は、ねじ部材６と一体に形成されてもよい。また、この他、第１実施形態及び第２実施形態におけるドレン１は、本発明の趣旨を逸脱しない範囲で設計変更可能である。   In addition, in 1st Embodiment and 2nd Embodiment, although the axial direction of the drain tube 3 inclines with respect to the direction perpendicular | vertical to the bottom part 20 of the eaves bowl 2, it may be parallel. Moreover, in 1st Embodiment and 2nd Embodiment, the downstream pipe connected with the drain tube 3 is not restricted to a call, and may be a joint or a rod such as an elbow. Further, the water passing member 5 in the first embodiment and the second embodiment may be formed integrally with the screw member 6. In addition, the drain 1 in the first embodiment and the second embodiment can be changed in design without departing from the spirit of the present invention.
