【発明の属する技術分野】
本発明は、洗面台や流し台、浴槽等の排水機器と、排水を下水側に排出する為の排水配管との接続に用いられる排水装置に関するものである。
BACKGROUND OF THE INVENTION
The present invention relates to a drainage device used for connecting drainage equipment such as a wash basin, a sink, and a bathtub and drainage piping for discharging drainage to the sewage side.
【従来の技術】
従来より、洗面台、流し台、浴槽など使用によって排水を生じる各種の機器（以後「排水機器」と呼ぶ）と、排水を下水側に排出する為の排水配管とを接続するために、図５に示したような排水装置が知られている。以下に、従来用いられてきた排水装置とその使用例を、図面を参照しつつ説明する。
[Prior art]
Conventionally, in order to connect various types of equipment that generates drainage by use of sinks, sinks, bathtubs, etc. (hereinafter referred to as “drainage equipment”) and drainage piping for discharging drainage to the sewage side, FIG. A drainage device as shown is known. Below, the drainage apparatus conventionally used and its usage example are demonstrated, referring drawings.
図５に示した排水装置は、以下に記した排水装置本体、及びフランジ部材から構成される。
排水装置本体は、内部に排水流路を形成する、排水装置の側面及び底面に配された外壁部と、該外壁部側面に設けた排出口と、排水装置本体の上方に配した、排水機器の取着孔周縁に当接する天板部と、該天板部に設けた、雌螺子部を有する開口部と、から成る。
フランジ部材は、排水装置本体の開口部の雌螺子部と螺合する雄螺子部を外周側壁に設けた筒状部と、該筒状部の上端側に外側方向に向けて突出させたフランジ部から成る。
The drainage device shown in FIG. 5 includes the drainage device main body and the flange member described below.
The drainage device body has a drainage channel disposed above the drainage device main body, an outer wall portion formed on the side surface and bottom surface of the drainage device, a discharge port provided on the side surface of the outer wall portion, and a drainage device body. The top plate portion is in contact with the periphery of the mounting hole, and the opening portion is provided on the top plate portion and has a female screw portion.
The flange member includes a cylindrical portion in which a male screw portion that engages with a female screw portion of the opening of the drainage device main body is provided on the outer peripheral side wall, and a flange portion that protrudes outward from the upper end side of the cylindrical portion. Consists of.
上記した排水装置を、例えば排水機器である防水パンに施工する場合、図５に示したように、防水パンに設けた取着孔に、フランジ部材の筒状部を挿通し、パッキングなどの水密部材を介して、フランジ部下面と、取着孔周縁の天板部を当接させる。
次に排水装置本体の開口部の雌螺子部に、フランジ部材の筒状部の外周面の雄螺子部を螺合させ、排水装置の取付が完了する。
更に排水装置の排出口に下水側の排水配管を接続して排水装置の施工が完了する。
When the drainage device described above is applied to a waterproof pan as a drainage device, for example, as shown in FIG. 5, the tubular portion of the flange member is inserted into an attachment hole provided in the waterproof pan, and watertightness such as packing is provided. Through the member, the lower surface of the flange portion is brought into contact with the top plate portion at the periphery of the attachment hole.
Next, the male screw portion on the outer peripheral surface of the cylindrical portion of the flange member is screwed into the female screw portion of the opening of the drainage device main body, and the attachment of the drainage device is completed.
Furthermore, drainage pipes on the sewage side are connected to the drainage outlet of the drainage device to complete the drainage device construction.
【発明が解決しようとする課題】
近年、マンションなどの集合住宅においては、各階の上下幅を狭くすることで、建物全体の高さを変更することなく、建物内の階数を増加しようとする傾向にある。この場合に、居住空間の高さ幅を狭めることは快適な生活の妨げになるため、床下の配管部分の高さ幅を狭めることで各階の上下幅を狭くする、所謂低床配管が増加している。この低床配管の達成のために、前述した排水装置などもその上下幅を可能な限り狭くすることが要求されている。
[Problems to be solved by the invention]
In recent years, apartment houses such as apartments tend to increase the number of floors in a building without changing the height of the entire building by narrowing the vertical width of each floor. In this case, narrowing the height of the living space hinders comfortable living, so increasing the so-called low-floor piping that narrows the vertical width of each floor by narrowing the height of the piping section under the floor increases. ing. In order to achieve this low-floor piping, the above-described drainage device and the like are also required to be as narrow as possible in the vertical width.
ところで、排水装置はフランジ部の雄螺子部と、排水装置本体の雌螺子部の螺合によって排水機器に取り付けられるが、排水機器の種類によって、また同種の排水機器でもその構造や形状によって、排水機器の取着孔周縁の厚みは様々である。例えば浴槽であれば、人工大理石又は陶器などで構成された浴槽の取着孔周縁の厚みは１０乃至２０ミリメートルほどであるのに対して、ステンレス製の浴槽では、取着孔周縁の厚みは４乃至５ミリメートル前後である。排水装置の雄螺子部は、取着孔の周縁部の厚みが最も大きい場合に対応できるように設計されているため、例えば取着孔の周縁の厚みが、最大で２０ミリメートル、平均的には５ミリメートルのような場合、つまり図６の様な場合、断面図の左右の差異からもわかるように、取着孔周縁が充分な厚みを備えていれば適切な係り強度となるように構成した排水装置では、取着孔周縁の厚みがさほど無いような場合、雄螺子部の先端は必要以上に螺合を進めることとなる。
By the way, the drainage device is attached to the drainage device by screwing the male screw portion of the flange portion and the female screw portion of the drainage device body, but depending on the type of drainage device, and the drainage device of the same type, depending on its structure and shape, The thickness of the periphery of the mounting hole of the device varies. For example, in the case of a bathtub, the thickness of the periphery of the attachment hole of the bathtub made of artificial marble or ceramics is about 10 to 20 mm, whereas in the case of a stainless steel bathtub, the thickness of the periphery of the attachment hole is 4 About 5 mm. Since the male screw portion of the drainage device is designed to cope with the case where the thickness of the peripheral portion of the attachment hole is the largest, for example, the thickness of the peripheral portion of the attachment hole is 20 mm at the maximum, In the case of 5 millimeters, that is, as shown in FIG. 6, as can be seen from the difference between the left and right of the cross-sectional view, if the peripheral edge of the mounting hole has a sufficient thickness, it is configured to have an appropriate engagement strength. In the drainage device, when the thickness of the peripheral edge of the attachment hole is not so much, the front end of the male screw portion is screwed more than necessary.
雌螺子部の下方に排水流路が形成されている排水装置において、上記段落０００５に記載したような理由により排水装置本体の高さ幅が狭まり、更に排水装置を施工する取着孔の厚みが比較的に薄い形状であった場合、図６の右側や、段落０００６に記載した従来例のように雄螺子部先端が必要以上に螺合し降下して、雌螺子部下方の排水流路に雄螺子部先端が到達し、排水流路の一部を閉塞して排水装置の排水性能を著しく悪化させる。
In the drainage device in which the drainage channel is formed below the female screw part, the height width of the drainage device body is narrowed for the reason described in the above paragraph 0005, and the thickness of the mounting hole for constructing the drainage device is further reduced. In the case of a relatively thin shape, the leading end of the male screw part is screwed more than necessary as in the conventional example described in the right side of FIG. 6 or paragraph 0006, and descends to the drainage flow path below the female screw part. The leading end of the male screw portion reaches and closes a part of the drainage flow path, thereby significantly deteriorating the drainage performance of the drainage device.
しかしながら、高さ幅が狭まった分だけフランジ部材の雄螺子部を狭めると、排水機器の取着孔周縁の厚みが最大となった場合、つまり段落０００６の例で有れば取着孔周縁の厚みが２０ミリメートル程度であった場合に、雄螺子部が雌螺子部に螺合できなくなったり、あるいは螺合しても数周りするだけで、充分な螺合強さが得られなくなってしまう。 これらの理由から、排水装置の汎用性を確保するために、排水流路の閉塞による排水性能の悪化という問題を生じつつ、排水装置の高さ方向を狭めている場合が殆どであった。
本発明は上記問題点に鑑み発明されたもので、螺合部分の係り強度を確保しながら排水装置の高さ幅を狭め、且つ排水流路の閉塞による排水性能の悪化を防ぐ排水装置を提供するものである。
However, if the male screw part of the flange member is narrowed by the height width, the thickness of the periphery of the attachment hole of the drainage device becomes the maximum, that is, in the example of paragraph 0006, When the thickness is about 20 millimeters, the male screw portion cannot be screwed into the female screw portion, or even if screwed, only a few turns will result in insufficient screwing strength. For these reasons, in order to ensure the versatility of the drainage device, the height direction of the drainage device is mostly narrowed while causing the problem of deterioration of drainage performance due to the blockage of the drainage channel.
The present invention has been invented in view of the above problems, and provides a drainage device that narrows the height of the drainage device while ensuring the engagement strength of the threaded portion and prevents deterioration of drainage performance due to blockage of the drainage channel. To do.

DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described below with reference to the drawings.
The embodiment of the present invention shown in FIG. 1 includes a drainage device main body (1), a flange member (7), and a packing (P) for watertightly connecting the two.
The drainage device main body (1) includes an outer wall portion (2) disposed on the side surface and the bottom surface, which forms a drainage channel therein, and a top plate portion (3) disposed above and contacting the periphery of the attachment hole of the drainage device ), A discharge port (4) provided on the side surface of the outer wall (2), and an opening (5) having a female screw portion (6), and further an opening (5) of the drainage device main body (1). ) It is provided with an upright part (11) rising in the vertical direction on the periphery. A female screw portion (6) extends from the opening portion (5) in the upright portion (11), and the height width of the male screw portion (8) described later is the top of the periphery of the opening portion (5). It is comprised so that it may become larger than the height width from a board part (3) to the upper end of the drainage flow path below an opening part (5).
The flange member (7) is provided with a male screw portion (9) that engages with the female screw portion (6) of the opening (5) of the drainage device main body (1) on the outer peripheral side wall, and further inside the drainage flow channel. It consists of a cylindrical part (8) provided with a drain port (12) that communicates, and a flange part (10) that protrudes outward from the upper end side of the cylindrical part (8).
上記排水装置を排水機器に取着する場合、排水機器の取着孔にパッキング（Ｐ）を取り付け、次に排水装置の立上部（１１）を排水機器の取着孔に当接させる。さらにフランジ部材（７）の雄螺子部（９）を、開口部（５）の雌螺子部（６）に螺合させると、排水装置本体（１）の天板部（３）上面と、フランジ部材（７）のフランジ部（１０）下面とで、排水機器の取着孔周縁を強く挟持して、排水装置の取着が完了する。
When the drainage device is attached to the drainage device, the packing (P) is attached to the attachment hole of the drainage device, and then the upright portion (11) of the drainage device is brought into contact with the attachment hole of the drainage device. Further, when the male screw portion (9) of the flange member (7) is screwed into the female screw portion (6) of the opening (5), the top surface of the top plate portion (3) of the drainage device main body (1), and the flange The attachment of the drainage device is completed by strongly holding the periphery of the attachment hole of the drainage device with the lower surface of the flange portion (10) of the member (7).
上記のように構成された排水装置を採用した排水機器を使用した場合、排水はフランジ部材（７）の排水口（１２）から排水流路を通って排出口（４）に到達し、更に下水側に排出される。
この際に、フランジ部材（７）の筒状部（８）下端は、排水装置本体（１）の中に形成されている排水流路の中に飛び出し、排水流路の一部を狭めたりすることがなく、或いは仮に一部を狭めることがあっても従来例の排水装置のそれよりも遙かに軽微なため、排水装置の排水性能が悪化することはほとんどない。
When the drainage device employing the drainage device configured as described above is used, the drainage reaches the drainage port (4) from the drainage port (12) of the flange member (7) through the drainage channel, and further sewage Discharged to the side.
At this time, the lower end of the cylindrical portion (8) of the flange member (7) jumps into the drainage channel formed in the drainage device main body (1) and narrows a part of the drainage channel. Even if a part of the drainage device is narrowed, the drainage performance of the drainage device is hardly deteriorated because it is much lighter than that of the conventional drainage device.
上記のように構成した本発明の実施例においては、開口部（５）の雌螺子部（９）は、立上部（１１）の分だけ上昇している。このため、立上部（１１）の高さ幅分だけフランジ部材（７）の雄螺子部（９）の高さ幅を減じても、従来例の排水装置と同じだけの係り強度を得ることができる。
これによって、図３の従来例（左側）と本発明の実施例（右側）の比較参考図からも明らかなように、立上部（１１）分だけ雄螺子部の下端が排水流路の中に入り込まないか、あるいは入り込んでも従来例に比べて排水流路の閉塞は緩和される。
In the embodiment of the present invention configured as described above, the female screw portion (9) of the opening portion (5) is raised by the rising portion (11). For this reason, even if the height width of the male screw portion (9) of the flange member (7) is reduced by the height width of the upright portion (11), the same engagement strength as that of the conventional drainage device can be obtained. it can.
Thus, as is apparent from the comparative reference diagram of the conventional example (left side) and the embodiment of the present invention (right side) in FIG. 3, the lower end of the male screw part is placed in the drainage flow path by the upright portion (11). Even if it does not enter, even if it enters, the blockage of the drainage channel is alleviated compared to the conventional example.
本発明の実施例は上記のようであるが、本発明は上記実施例に限定されるものではなく、発明の要旨を変更しない範囲で様々な変更が可能である。
例えば、上記実施例においては、排水装置を、排水エルボと呼ばれる、内部に排水が単純に流れるような構造としているが、図４に示したように、下水側から臭気や害虫類が逆流してくることを防止する機能を備えた排水装置としても上記実施例と同様の効果を得ることができる。
The embodiments of the present invention are as described above, but the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.
For example, in the above embodiment, the drainage device has a structure called drainage elbow, in which drainage simply flows inside, but as shown in FIG. 4, odors and pests flow backward from the sewage side. An effect similar to that of the above-described embodiment can be obtained also as a drainage device having a function of preventing spilling.
本発明は上記のように構成したため、以下のような優れた効果を奏する。
１）請求項１及び請求項２に記載の本発明に置いては、排水装置の開口部に立ち上がり部を設け、該立上部内にも雌螺子部を延設したため、螺合の係り強度を確保したまま、立上部の分だけフランジ部材の雄螺子部を幅狭とすることができ、排水流路の閉塞が無くなったり、又は閉塞を緩和することができる。
２）請求項３に記載の本発明においては、１）に記載した効果を、トラップ機能を備えた排水装置に付与することができる。
