Description

本発明は、枠材に溜まった水を排水する排水装置、及び当該排水装置を備えた建具に関する。 The present invention relates to a drainage device for draining water accumulated in a frame material and a fitting provided with the drainage device.

従来、枠材に取り付けられ、当該枠材に溜まった水を排水する排水装置が知られている（例えば、特許文献１参照）。
特許文献１に記載の排水装置は、鉛直方向に沿って貫通した排水路を有する筒体と、排水路に設けられ、排水位置及び非排水位置にそれぞれ移動可能とする弁体とを備える。
ここで、弁体は、通常、自重によって排水位置に位置付けられる。当該排水位置では、筒体の内周面に設けられた通水口と弁体とには隙間が設けられる。これにより、排水路に浸入した水は、当該隙間を介して、排水される。
また、弁体は、排水装置外部から圧力が与えられることによって、上方に移動し、通水口を閉塞する。これにより、排水装置外部から当該排水装置を介して雨水や風等が逆流することを回避している。 Conventionally, a drainage device that is attached to a frame material and drains water accumulated in the frame material is known (see, for example, Patent Document 1).
The drainage device described in Patent Document 1 includes a cylinder having a drainage channel penetrating along the vertical direction, and a valve body provided in the drainage channel and capable of moving to a drainage position and a non-drainage position, respectively.
Here, the valve body is usually positioned at the drainage position by its own weight. At the drainage position, a gap is provided between the water passage port provided on the inner peripheral surface of the cylinder and the valve body. As a result, the water that has entered the drainage channel is drained through the gap.
Further, the valve body moves upward by applying pressure from the outside of the drainage device and closes the water passage port. This prevents rainwater, wind, etc. from flowing back from the outside of the drainage device through the drainage device.

しかしながら、特許文献１に記載の排水装置では、通常の状態において、排水を行う必要があるため、弁体と通水口との間には、所定の隙間がある。このため、無風状態も含む日常的な風（例えば１２ｍ／ｓ以下の風）が吹いているレベルの環境下において、屋外の風が排水装置（当該隙間）を介して屋内に流入してしまう、という問題がある。 However, in the drainage device described in Patent Document 1, since it is necessary to drain water in a normal state, there is a predetermined gap between the valve body and the water passage port. For this reason, in an environment where daily winds (for example, winds of 12 m / s or less) are blowing, including a windless state, outdoor winds flow into the room through the drainage device (the gap). There is a problem.

すなわち、排水装置６が貫通孔２１８に取り付けられた状態では、天面部１０は、第２の筒体１２と同様に、見込み壁部２１４の上面よりも＋Ｚ軸側の位置に位置付けられるとともに、＋Ｚ軸側から見た場合に、その外周面が貫通孔２１８の内周面よりも外側の位置に位置付けられる。 The top surface portion 10 has a disk shape having substantially the same outer diameter dimension as the outer diameter dimension of the second cylinder body 12, and the second cylinder body is in a posture coaxial with the second cylinder body 12. It is integrally formed on the end face of 12 on the + Z axis side.
That is, in the state where the drainage device 6 is attached to the through hole 218, the top surface portion 10 is positioned at a position on the + Z axis side of the upper surface of the prospective wall portion 214 and is + Z, similarly to the second tubular body 12. When viewed from the shaft side, the outer peripheral surface thereof is positioned outside the inner peripheral surface of the through hole 218.

以上説明した排水装置本体７の＋Ｚ軸側には、側方（Ｘ軸方向）にそれぞれ開口し、排水路ＰＡと当該排水装置本体７外部とをそれぞれ連通する２つの受入口ＯＰが設けられている。なお、当該２つの受入口ＯＰは、設けられた位置が異なるのみであり、同一の形状を有する。
具体的に、受入口ＯＰは、矩形状の開口である。そして、受入口ＯＰの＋Ｚ軸側の縁部は、天面部１０の下面１００によって構成されている。また、受入口ＯＰのＹ軸方向両側の縁部は、第２の筒体１２によって構成されている。さらに、受入口ＯＰの−Ｚ軸側の縁部は、第１の筒体１１によって構成されている。 On the + Z-axis side of the drainage device main body 7 described above, two receiving / receiving OPs are provided, which are opened laterally (in the X-axis direction) and communicate with the drainage channel PA and the outside of the drainage device main body 7. There is. The two inlet OPs have the same shape, only the positions where they are provided are different.
Specifically, the entrance OP is a rectangular opening. The + Z-axis side edge of the receiving port OP is composed of the lower surface 100 of the top surface portion 10. Further, the edges of the receiving port OP on both sides in the Y-axis direction are formed by the second tubular body 12. Further, the edge portion of the receiving port OP on the −Z axis side is formed by the first tubular body 11.

ここで、天面部１０の下面１００は、２つの第１の傾斜面１０１と、中央水平面１０２とによって構成されている（図５，図６）。
２つの第１の傾斜面１０１は、２つの受入口ＯＰの＋Ｚ軸側の縁部をそれぞれ構成し、下面１００の外縁から当該下面１００の中心（中心軸Ａｘ）に向かうにしたがって−Ｚ軸側にそれぞれ傾斜した平坦面である。
中央水平面１０２は、２つの第１の傾斜面１０１の間の中心軸Ａｘ上に位置し、ＸＹ平面に平行となる平坦面である。 Here, the lower surface 100 of the top surface portion 10 is composed of two first inclined surfaces 101 and a central horizontal plane 102 (FIGS. 5 and 6).
The two first inclined surfaces 101 form the + Z-axis side edges of the two inlet OPs, respectively, and the -Z-axis side is directed from the outer edge of the lower surface 100 toward the center (central axis Ax) of the lower surface 100. It is a flat surface that is inclined to each.
The central horizontal plane 102 is a flat plane located on the central axis Ax between the two first inclined planes 101 and parallel to the XY plane.

また、第２の筒体１２には、受入口ＯＰのＹ軸方向両側の縁部をそれぞれ構成する２つの第２の傾斜面１２１が設けられている（図２，図３，図６）。
２つの第２の傾斜面１２１は、排水路ＰＡから排水装置本体７外部に向かうにしたがって２つの受入口ＯＰの開口面積をそれぞれ拡げるように傾斜した平坦面である。
なお、排水装置６が貫通孔２１８に取り付けられた状態では、２つの受入口ＯＰの−Ｚ軸側の縁部は、見込み壁部２１４の上面よりも−Ｚ軸側の位置に位置付けられる（図５）。一方、第１，第２の傾斜面１０１，１２１は、見込み壁部２１４の上面よりも＋Ｚ軸側の位置に位置付けられる（図５）。 Further, the second tubular body 12 is provided with two second inclined surfaces 121 each forming edges on both sides of the receiving port OP in the Y-axis direction (FIGS. 2, FIG. 3, FIG. 6).
The two second inclined surfaces 121 are flat surfaces inclined so as to expand the opening areas of the two receiving / receiving OPs toward the outside of the drainage device main body 7 from the drainage channel PA.
In the state where the drainage device 6 is attached to the through hole 218, the edges of the two inlet OPs on the −Z axis side are positioned at positions on the −Z axis side of the upper surface of the prospective wall portion 214 (FIG. 5). On the other hand, the first and second inclined surfaces 101 and 121 are positioned at positions on the + Z axis side of the upper surface of the prospective wall portion 214 (FIG. 5).

そして、見込み壁部２１４の上面に溜まり、受入口ＯＰ内まで浸入した水ＷＡ（図５で一点鎖線で図示）は、第１の傾斜面１０１や第２の傾斜面１２１に接触すると、その表面張力によって中心軸Ａｘ側に引き寄せられる。そして、当該水ＷＡは、排水路ＰＡ内において、自重により落下していく。
特に、第１，第２の傾斜面１０１，１２１が上述したように傾斜しているため、水ＷＡが当該第１，第２の傾斜面１０１，１２１に接触し易い構造となっている。また、排水装置６が親水性の高い樹脂材料によって構成されているため、水ＷＡが第１，第２の傾斜面１０１，１２１に接触した後、その表面張力によって当該水ＷＡを中心軸Ａｘ側に引き寄せ易い構造となっている。 Then, when the water WA (shown by the alternate long and short dash line in FIG. 5) that has accumulated on the upper surface of the prospective wall portion 214 and has penetrated into the receiving port OP comes into contact with the first inclined surface 101 and the second inclined surface 121, the surface thereof. It is attracted to the central axis Ax side by tension. Then, the water WA falls due to its own weight in the drainage channel PA.
In particular, since the first and second inclined surfaces 101 and 121 are inclined as described above, the structure is such that the water WA can easily come into contact with the first and second inclined surfaces 101 and 121. Further, since the drainage device 6 is made of a highly hydrophilic resin material, after the water WA comes into contact with the first and second inclined surfaces 101 and 121, the water WA is moved to the central axis Ax side by the surface tension thereof. It has a structure that is easy to attract to.

〔弁体の動作〕
次に、上述した弁体８の動作について図８を参照しつつ説明する。
図８は、図４に対応した断面図であって、弁体８の動作を説明する図である。具体的に、図８（ａ）は、弁体８が通常位置に位置付けられた状態を示す図である。図８（ｂ）は、弁体８が弁開位置に位置付けられた状態を示す図である。図８（ｃ）は、弁体８が弁閉位置に位置付けられた状態を示す図である。
弁体８は、通常、図８（ａ）に示した通常位置に位置付けられる。
当該通常位置は、弁体８の自重によってバランスが取れた状態である。当該通常位置では、一対の回転軸部８３は、一対の長穴１１６内において、当該長穴１１６の長手方向の一端側（−Ｚ軸側）に位置する。また、当該通常位置では、第１の止水面１１２と第２の止水面８５との間には、隙間が設けられている。なお、以下では、当該隙間を第１の隙間と記載する。 [Operation of valve body]
Next, the operation of the valve body 8 described above will be described with reference to FIG.
FIG. 8 is a cross-sectional view corresponding to FIG. 4, and is a diagram for explaining the operation of the valve body 8. Specifically, FIG. 8A is a diagram showing a state in which the valve body 8 is positioned at a normal position. FIG. 8B is a diagram showing a state in which the valve body 8 is positioned at the valve opening position. FIG. 8C is a diagram showing a state in which the valve body 8 is positioned at the valve closed position.
The valve body 8 is usually positioned at the normal position shown in FIG. 8 (a).
The normal position is in a state balanced by the weight of the valve body 8. In the normal position, the pair of rotating shaft portions 83 are located on one end side (−Z axis side) of the elongated holes 116 in the longitudinal direction in the pair of elongated holes 116. Further, at the normal position, a gap is provided between the first water stop surface 112 and the second water stop surface 85. In the following, the gap will be referred to as a first gap.

弁体８が通常位置に位置付けられた状態において、受入口ＯＰを介して排水路ＰＡに浸入し、当該排水路ＰＡを辿って落下した水ＷＡは、堰止部８０に溜まる。そして、弁体８は、当該水ＷＡから荷重を受けることによって、一対の回転軸部８３を中心として図８中、反時計回りに回動し、図８（ｂ）に示した弁開位置に位置付けられる。
当該弁開位置では、第１の止水面１１２と第２の止水面８５との隙間は、第１の隙間よりも大きい第２の隙間となる。これにより、堰止部８０に溜まった水ＷＡは、当該第２の隙間を介して空間ＳＰに排水される。 In the state where the valve body 8 is positioned at the normal position, the water WA that has entered the drainage channel PA through the receiving port OP and has fallen along the drainage channel PA is collected in the dammed portion 80. Then, when the valve body 8 receives a load from the water WA, it rotates counterclockwise in FIG. 8 about the pair of rotating shaft portions 83, and reaches the valve opening position shown in FIG. 8 (b). Positioned.
At the valve opening position, the gap between the first water stop surface 112 and the second water stop surface 85 is a second gap larger than the first gap. As a result, the water WA collected in the dammed portion 80 is drained to the space SP through the second gap.

また、弁体８が通常位置または弁開位置に位置付けられた状態において、屋外空間から空間ＳＰに入り込んだ雨水や風等によって、排水装置６外部から弁体８に圧力が与えられると、弁体８は、一対の回転軸部８３が一対の長穴１１６によって移動が案内されつつ、＋Ｚ軸側に向けて移動し、図８（ｃ）に示す弁閉位置に位置付けられる。
当該弁閉位置では、一対の回転軸部８３は、一対の長穴１１６内において、当該長穴１１６の長手方向の他端側（＋Ｚ軸側）に位置する。また、当該弁閉位置では、第１の止水面１１２に対して第２の止水面８５が当接する。すなわち、屋外空間から空間ＳＰに入り込んだ雨水や風等は、排水装置６を介して、屋内空間に入り込むことがない。 Further, when the valve body 8 is positioned at the normal position or the valve open position and pressure is applied to the valve body 8 from the outside of the drainage device 6 by rainwater or wind that has entered the space SP from the outdoor space, the valve body 8 is positioned. Reference numeral 8 denotes a pair of rotating shaft portions 83 that move toward the + Z axis side while being guided by a pair of elongated holes 116, and are positioned at the valve closing position shown in FIG. 8 (c).
At the valve closed position, the pair of rotating shaft portions 83 are located on the other end side (+ Z axis side) of the elongated holes 116 in the longitudinal direction in the pair of elongated holes 116. Further, at the valve closed position, the second water stop surface 85 comes into contact with the first water stop surface 112. That is, rainwater, wind, etc. that have entered the space SP from the outdoor space do not enter the indoor space via the drainage device 6.

本発明に係る排水装置は、枠材に溜まった水を排水する排水装置であって、鉛直方向に沿って貫通した排水路を有する筒体と、前記排水路に設けられ、通常位置、弁開位置、及び弁閉位置にそれぞれ移動可能とする弁体とを備え、前記筒体の内周面には、前記弁体が当接する止水面が設けられ、前記筒体及び前記弁体の一方の部材には、長穴が設けられ、前記筒体及び前記弁体の他方の部材には、前記長穴に挿通される回転軸部が設けられ、前記通常位置は、前記回転軸部が前記長穴の長手方向の一端側に位置し、前記止水面と前記弁体との隙間が第１の隙間となる位置であり、前記弁開位置は、前記通常位置に位置付けられた前記弁体が前記回転軸部を中心として回動し、前記止水面と前記弁体との隙間が前記第１の隙間よりも大きい第２の隙間となる位置であり、前記弁閉位置は、前記回転軸部が前記長穴の長手方向の他端側に位置し、前記止水面に前記弁体が当接する位置であることを特徴とする。 The drainage device according to the present invention is a drainage device for draining water accumulated in a frame material, and is provided with a cylinder having a drainage channel penetrating in the vertical direction and a drainage channel provided in the drainage channel at a normal position and valve opening. A valve body that can be moved to a position and a valve closing position is provided, and a water blocking surface that the valve body comes into contact with is provided on the inner peripheral surface of the cylinder body, and one of the cylinder body and the valve body is provided. The member is provided with an elongated hole, and the other member of the tubular body and the valve body is provided with a rotating shaft portion to be inserted into the elongated hole. It is located on one end side in the longitudinal direction of the hole, and the gap between the water stop surface and the valve body is the first gap, and the valve opening position is such that the valve body positioned at the normal position is the valve body. It rotates around the rotation shaft portion, and the gap between the water stop surface and the valve body is a second gap larger than the first gap. The valve closing position is the position where the rotation shaft portion is located. It is located on the other end side of the elongated hole in the longitudinal direction, and is characterized at a position where the valve body abuts on the water blocking surface.

本発明では、弁体は、通常、自重によって上述した通常位置に位置付けられる。そして、通常位置に位置付けられた弁体は、受入口を介して排水路に浸入した水から荷重を受けることによって、回転軸部を中心として回動し、上述した弁開位置に位置付けられる。これにより、受入口を介して排水路に浸入した水は、排水される。また、弁体は、排水装置外部から圧力が与えられることによって、長穴及び回転軸部によって移動が案内され、上述した弁閉位置に位置付けられる。これにより、排水装置外部から当該排水装置を介して雨水や風等が逆流することを回避することができる。
ここで、通常位置では、止水面と弁体との隙間（第１の隙間）は、弁開位置での隙間（第２の隙間）よりも小さい隙間である。すなわち、通常の状態において、排水を行う必要がないため、止水面と弁体との隙間（第１の隙間）を比較的に小さくすることができる。このため、無風状態も含む日常的な風（例えば１２ｍ／ｓ以下の風）が吹いているレベルの環境下において、屋外の風が排水装置（当該隙間）を介して屋内に流入することを抑制することができる。 In the present invention, the valve body is usually positioned by its own weight in the above-mentioned normal position. Then, the valve body positioned at the normal position rotates about the rotation shaft portion by receiving a load from the water that has entered the drainage channel through the receiving port, and is positioned at the valve opening position described above. As a result, the water that has entered the drainage channel through the receiving port is drained. Further, when pressure is applied from the outside of the drainage device, the valve body is guided to move by the elongated hole and the rotating shaft portion, and is positioned at the valve closing position described above. As a result, it is possible to prevent rainwater, wind, or the like from flowing back from the outside of the drainage device through the drainage device.
Here, at the normal position, the gap between the water blocking surface and the valve body (first gap) is smaller than the gap at the valve opening position (second gap). That is, since it is not necessary to drain the water under the normal state, the gap (first gap) between the water blocking surface and the valve body can be made relatively small. For this reason, it is possible to prevent outdoor wind from flowing into the room through the drainage device (the gap) in an environment where daily wind (for example, wind of 12 m / s or less) is blowing, including in a windless state. can do.

また、本発明は、上述した排水装置において、前記長穴の長手方向は、鉛直方向に対して傾斜していることを特徴とする。
本発明によれば、長穴の長手方向が鉛直方向に対して傾斜しているため、止水面から離間した位置において弁体を通常位置から弁開位置へと回動する構造を採用することができる。すなわち、弁体が回動した際に当該弁体と機械的に干渉しない位置に止水面を設けることができる。このため、弁体が弁閉位置に位置付けられた際に当該弁体と止水面との当接を確実に実施させ、当該弁閉位置での止水性能を向上させることができる。 Further, the present invention is characterized in that, in the drainage device described above, the longitudinal direction of the elongated hole is inclined with respect to the vertical direction.
According to the present invention, since the longitudinal direction of the elongated hole is inclined with respect to the vertical direction, it is possible to adopt a structure in which the valve body rotates from the normal position to the valve opening position at a position away from the water blocking surface. it can. That is, the water stop surface can be provided at a position where the valve body does not mechanically interfere with the valve body when the valve body rotates. Therefore, when the valve body is positioned at the valve closed position, the valve body and the water stop surface can be reliably brought into contact with each other, and the water stop performance at the valve closed position can be improved.

また、本発明は、上述した排水装置において、前記長穴は、前記筒体に設けられ、前記回転軸部は、前記弁体に設けられていることを特徴とする。

Compared with the configuration, the assemblability of the drainage device can be improved.

また、本発明は、上述した排水装置において、前記弁体には、上方に向けて開口する堰止部が設けられていることを特徴とする。
本発明によれば、弁体に上述した堰止部が設けられているため、排水路に浸入した水によって弁体を通常位置から弁開位置へと円滑に回動させることができる。 Further, the present invention is characterized in that, in the drainage device described above, the valve body is provided with a dam portion that opens upward.
According to the present invention, since the valve body is provided with the above-mentioned dammed portion, the valve body can be smoothly rotated from the normal position to the valve open position by the water that has entered the drainage channel.

また、本発明に係る建具は、四周枠組みされた枠体と、前記枠体に支持される面材とを備えた建具であって、上述した排水装置を備え、前記排水装置は、前記枠体を構成する下枠の上面において、前記面材よりも屋内側に位置する部分に取り付けられていることを特徴とする。
本発明によれば、上述した排水装置を上述した位置に取り付けることで、枠体や面材の屋内側に臨む面に生じた結露によって下枠に溜まった水を当該排水装置によって屋外側に排水することができ、屋内空間の快適性を確保することができる。 Further, the fitting according to the present invention is a fitting provided with a frame body having a four-circumferential framework and a face material supported by the frame body, and includes the above-mentioned drainage device, and the drainage device is the frame body. It is characterized in that it is attached to a portion of the upper surface of the lower frame constituting the above, which is located on the indoor side of the face material.
