Description

本発明は、低床仕様、バリアフリー対策として、浴槽の跨ぎ高さが可能な限り低くされた遠隔操作式排水栓装置を備えた浴槽の排水口と、防水パンの排水口との、これらが接続される排水接続構造に関するものである。  As a low floor specification and barrier-free measure, the present invention includes a drainage port of a bathtub equipped with a remote-controlled drainage device whose height across the bathtub is as low as possible and a drainage port of a waterproof pan. The present invention relates to a drainage connection structure to be connected.

従来から、高層マンション化による低床仕様と、バリアフリー対策とによって、浴槽の跨ぎ高さが可能な限り低くされ、遠隔操作式排水栓装置を備えた浴槽底部と防水パンとの空間の高さを抑えた排水接続構造が待望されている。
遠隔操作式排水栓装置を備えた浴槽の排水口と防水パンの排水口との排水接続構造には、これらが接続される接続継手を備え、該接続継手は、周面に遠隔操作を排水栓へ伝達するレリースワイヤが挿通される技管(挿通部)を備え、この接続継手が、防水パンの排水口への接続に際して、水密性を保持する上で、両者の平面方向及び垂直方向の寸法誤差を吸収する調整手段(蛇腹状筒)を介在するものである。
Conventionally, the height of the space between the bottom of the bathtub with a remote-operated drain plug device and the waterproof pan has been reduced as much as possible by the low floor specification due to high-rise apartments and barrier-free measures. There is a long-awaited drainage connection structure that suppresses the above.
The drainage connection structure of the drainage port of the bathtub and the drainage port of the waterproof pan equipped with the remote control type drainage device is equipped with a connection joint to which these are connected. In order to maintain watertightness when connecting the waterproof pan to the drain outlet, the connecting pipe is equipped with a technical tube (insertion section) through which the release wire that is transmitted to is inserted. An adjustment means (bellows-shaped cylinder) for absorbing the error is interposed.

接続継手は、浴槽の排水口を貫通した排水口金具にねじ込み装着し、浴槽の排水口の縁を挟み込み、接続継手の下端には防水パンの排水口よりも小径にして当該排水口内を平面方向及び垂直方向に移動可能に突設した接続排水管と、該接続排水管の下端よりも上方に周設した防水パンの排水口よりも大径のフランジとが形成され、該フランジと防水パンの排水口とを、水密状に密着し、該フランジの位置高さの自動調整をし、このような調整手段が配設されているものである(特許文献1)。  The joint is screwed into the drain fitting that penetrates the drain of the bathtub, the edge of the drain of the bathtub is sandwiched, and the lower end of the joint is smaller than the drain of the waterproof pan, and the inside of the drain is planar And a connecting drain pipe projecting so as to be movable in the vertical direction, and a flange having a diameter larger than the drain opening of the waterproof pan provided above the lower end of the connecting drain pipe. A drain outlet is closely attached in a watertight manner, and the position height of the flange is automatically adjusted, and such an adjusting means is provided (Patent Document 1).

また、浴槽の排水口と防水パンの排水口との排水接続構造が、円筒状の本体の上部に浴槽への取付用のフランジを形成し、下部に防水パンの排水口へ取付けた軟質部材(蛇腹)と接合するリング状の接合部(フランジ)を形成し、この接合部の下面を傾斜面とする接続継手(直落しナット)でなり、防水パンの排水口に浴槽の排水口を接続する際に、接続継手の接合部が防水パンの排水口に取付けられた軟質部材を押し潰す状態になって水密性を確保するものである(特許文献2)。  Moreover, the drainage connection structure of the drainage port of the bathtub and the drainage port of the waterproof pan forms a flange for attachment to the bathtub at the upper part of the cylindrical main body, and the soft member attached to the drainage port of the waterproof pan at the lower part ( Forms a ring-shaped joint (flange) that joins the bellows, and consists of a connection joint (direct drop nut) with the bottom surface of this joint as an inclined surface, and connects the drain of the bathtub to the drain of the waterproof pan At this time, the joint portion of the connection joint crushes the soft member attached to the drain of the waterproof pan to ensure water tightness (Patent Document 2).

周面に遠隔操作を排水栓へ伝達するレリースワイヤが挿通される枝管を備え、防水パンの排水口への接続の際に、調整手段を介在させて水密性を確保するようにした接続継手でなる排水接続構造(特許文献1)においては、接続継手が浴槽を排水口金具とで挟持締着させるナットを兼ねることになって、高層マンション化による低床仕様、バリアフリー対策における浴槽の跨ぎ高さを可能な限り低くし、浴槽底部と防水パンとの空間の高さを抑えるという点について、一応解決したかに見えたが、接続継手の下端に、防水パンの排水口に差込み接続する接続排水管を備え、水密性のために介在させた調整手段は、接続構造を複雑化し、複雑化したが故に、接続施工の容易性を欠くことになり、施工後の修理にも事欠き、不都合である。  A connecting joint that has a branch pipe through which a release wire that transmits remote operation to the drain plug is inserted on the peripheral surface, and that ensures watertightness by interposing an adjustment means when connecting to the drain outlet of the waterproof pan In the drainage connection structure (Patent Document 1), the connecting joint also serves as a nut that clamps and fastens the bathtub with the drainage fitting, so that the low floor specification due to the high-rise apartment building and the straddle of the bathtub in a barrier-free measure It seemed that the height of the space between the bottom of the bathtub and the waterproof pan was reduced as much as possible, but it seemed to be solved temporarily, but it was inserted into the drain of the waterproof pan at the lower end of the joint. The adjustment means provided with a connection drain pipe and interposed for water tightness makes the connection structure complicated and complicated, so that the connection construction is not easy and the repair after the construction is also lacking and inconvenient. It is.

また、円筒状の本体の上部に、浴槽への取付用フランジを形成し、その下部に、防水パンの排水口へ取付けられた軟質部材と接合する下面を傾斜面とするリング状接合部を形成した接続継手でなる排水接続構造(特許文献2)においては、接続継手が、一応、単純な構造になったが、防水パンの排水口に取付けられた軟質部材を押し潰し、水密性を確保する施工の際、排水接続構造が浴槽の陰になって見えない状態で、軟質部材に接続継手の接続部を位置合せしなければならず、平面方向及び垂直方向へ移動し、水密状に密着させることは非常に困難で、時間を要し、不都合である。
また、この接続継手には、遠隔操作を排水栓に伝達するレリースワイヤが挿通される挿通部を備えておらず、接続継手の接合部と防水パンの排水口に取付けられた軟質部材と間に挟めた状態で引き出すことは、そこに隙間を生じ易く、水密性に支障を来すと共に、接続継手による防水パンの排水口への接続施工時に、レリースワイヤが邪魔し、作業の円滑化を為難くしている。
In addition, a flange for attachment to the bathtub is formed on the upper part of the cylindrical body, and a ring-shaped joint having a lower surface that joins a soft member attached to the drain of the waterproof pan is formed on the lower part of the flange. In the drainage connection structure (Patent Document 2) composed of the connected joint, the connection joint has a simple structure, but the soft member attached to the drainage port of the waterproof pan is crushed to ensure water tightness. At the time of construction, the connection part of the connection joint must be aligned with the soft member in the state where the drainage connection structure is hidden behind the bathtub, and it moves in the plane direction and the vertical direction so that it adheres in a watertight manner. It is very difficult, time consuming and inconvenient.
In addition, this connection joint does not have an insertion part through which a release wire for transmitting remote operation to the drain plug is inserted, and is not provided between the joint part of the connection joint and the soft member attached to the drain of the waterproof pan. Pulling it out in a pinched state tends to create a gap there, hindering water tightness, and at the time of connecting the waterproof pan to the drainage port with a connection joint, the release wire obstructs the work. It is difficult.

そこで、本発明の排水接続構造は、浴槽の排水口と防水パンの排水口とを接続する接続継手が、浴槽を遠隔操作式排水栓装置の支持備えられた排水口金具とで挟持締着する直落しナットに兼用されることになり、この直落しナットが直筒状本体、本体の上下端に上下対称の外向きフランジを形成し、上下対称であるので、方向性を考慮せずに排水口金具に簡単且つ容易に螺合することができ、また、下方になった外向きフランジには、容易に軟質パッキンを取付けられ、このことによって、構造が簡単で、防水パンの排水口との水密性の確保でき、そして容易に施工しやすくできることを目的とする。  Therefore, in the drainage connection structure of the present invention, the connection joint that connects the drainage port of the bathtub and the drainage port of the waterproof pan clamps and fastens the bathtub with the drainage fitting provided to support the remotely operated drainage plug device. This straight drop nut is also used as a straight drop nut. The straight drop nut forms a vertically symmetric outward flange on the upper and lower ends of the main body. It can be easily and easily screwed onto the bracket, and the downwardly facing outward flange can be easily attached with a soft packing, which makes the structure simple and watertight with the drain of the waterproof pan. The purpose is to be able to secure the property and to easily install.

更に、浴槽の跨ぎ高さを可能な限り低くすることができ、そして、低くなったからとて、レリースワイヤを挿通する枝管が形成され、直落しナットへのレリースワイヤの挿通に支障しないことを目的とする。  Furthermore, the height across the bathtub can be reduced as much as possible, and a branch pipe through which the release wire is inserted is formed only when the height is lowered, so that it does not hinder the insertion of the release wire directly into the nut. Objective.

本発明の排水接続構造は、浴槽を防水パンに載置し、該防水パンの排水口に対して浴槽の排水口を接続するに当って、浴槽が遠隔操作式排水栓装置を支持備えた排水口金具とで締着される直落しナットが、直筒状の本体を上下対称とし、その上下端に上下対称の外向きフランジを形成し、直筒状の本体内周面全体に内ネジを形成し、前記下外向きフランジには、該下外向きフランジと防水パンの排水口とを接続する軟質パッキンを介在するものである。  In the drainage connection structure of the present invention, the tub is placed on the waterproof pan, and the drainage of the bathtub is connected to the drainage port of the waterproof pan. The straight drop nuts fastened with the fittings make the straight cylindrical body vertically symmetric, form vertically symmetric outward flanges at the upper and lower ends, and form internal threads on the entire inner surface of the straight cylindrical body. The downward outward flange is provided with a soft packing that connects the downward outward flange and the drain of the waterproof pan.

本発明の排水接続構造は、直落しナットが直筒状の本体の上下対称の中間位置に遠隔操作式のレリースワイヤを挿通する枝管を配設するものである。  In the drainage connection structure of the present invention, a branch pipe through which a remote-controlled release wire is inserted is disposed at a vertically symmetrical intermediate position of a main body having a straight drop nut.

本発明の排水接続構造は、直落しナットが直筒状の本体の上下対称の中間位置で、且つ本体の筒壁上に、その軸心より軸が離れた遠隔操作式のレリースワイヤを挿通する枝管を配設するものである。  In the drainage connection structure of the present invention, the branch nut is inserted through a remote-control-type release wire having a straight drop nut at a vertically symmetrical intermediate position of the straight cylindrical main body and on the cylindrical wall of the main body and whose axis is separated from the axis. A tube is provided.

本発明の排水接続構造は、直落しナットが、直筒状の上下対称の中間位置で、且つ本体の筒壁上に遠隔操作式レリースワイヤの挿通する枝管を配設し、該枝管がその軸を本体の筒壁接線上とし、蝸牛状とするものである。  In the drainage connection structure of the present invention, the straight drop nut is arranged in a straight cylindrically symmetrical middle position, and a branch pipe through which the remotely operated release wire is inserted is arranged on the cylindrical wall of the main body, and the branch pipe is The shaft is on the cylinder wall tangent of the main body, and is a cochlea shape.

本発明の排水接続構造は、浴槽が上下対称の直落しナットと排水口金具とで締着され、その直落しナットの下外向きフランジに防水パンの排水口を接続する軟質パッキンが取付けられるだけの構造簡単で、且つ部品点数を少なくした、組付け簡単、且つ容易に、それでいて水密性の確保ができる。  In the drainage connection structure of the present invention, the bathtub is fastened with a vertically falling nut and a drainage fitting, and a soft packing that connects the drainage port of the waterproof pan is attached to the downwardly outward flange of the nut. The structure is simple, the number of parts is reduced, the assembly is simple and easy, and the watertightness can be ensured.

そして、遠隔操作式レリースワイヤの挿通する枝管が直落しナットの中間位置にあるので、浴槽への締着時に、排水口金具と、方向性を考慮せず容易に取付けることができる。  And since the branch pipe which a remote control type release wire penetrates falls directly and exists in the intermediate position of a nut, it can attach easily without considering a drain outlet metal fitting at the time of fastening to a bathtub.

直落しナットの遠隔操作式レリースワイヤの挿通する枝管が、直落しナット本体の筒壁上にその軸心より軸を外して配設されているので、排水口金具に支持備えた遠隔操作式排水栓の作動部より直落しナットの筒壁へ挿通させるレリースワイヤが屈折せずに、緩慢な曲げにすることができ、レリースワイヤの遠隔操作機能を良好にすると共に、耐久性をも向上させることができる。
なお、遠隔操作式レリースワイヤを挿通する枝管が、その軸を直落しナット本体の筒壁の接線上になるように配設されることによって、その効果は一層向上することになる。

The release wire that is dropped directly from the working part of the drain plug and inserted into the cylinder wall of the nut can be bent gently without bending, improving the remote control function of the release wire and improving durability. be able to.
In addition, the effect is further improved by arranging the branch pipe through which the remote-operated release wire is inserted so that its shaft is dropped directly on the tangent line of the cylinder wall of the nut body.
In addition, the branch pipe is directly dropped and disposed on the cylinder wall of the nut body with its shaft off the axis, or the branch pipe falls directly on the axis of the nut wall and is tangent to the cylinder wall of the nut body. By being arranged in this way, the arrangement direction of the branch pipes can be reversed by directly turning the nut downward. Therefore, the direction in which the release wire is inserted can be reversed.

本発明は、低床仕様、バリアフリー対策によって、浴槽の底部と防水パンとの空間の高さが可能な限り抑えられた、その為の浴槽の排水口と防水パンの排水口との排水接続構造である。
排水接続構造は、図1に示す如く、防水パン2の排水口20に対して浴槽1の排水口10の縁を接続するに当って、浴槽1が、遠隔操作式排水栓装置11を支持備えた排水口金具12に直落しナット3をパッキン13を介して螺合することによって、該排水口金具と直落しナット3とで挟持締着される。
According to the present invention, the height of the space between the bottom of the bathtub and the waterproof pan is suppressed as much as possible by the low floor specification and the barrier-free measure, and the drain connection between the drain of the bathtub and the drain of the waterproof pan for that purpose. Structure.
As shown in FIG. 1, the drainage connection structure supports the remote-operated drain plug device 11 when the edge of the drainage port 10 of the bathtub 1 is connected to the drainage port 20 of the waterproof pan 2. The nut 3 is directly dropped onto the drain fitting 12 and screwed into the nut 3 via the packing 13 so that the drain fitting and the nut 3 are clamped and clamped.

直落しナット3は、直筒状の本体31が上下対称とされ、その中間位置に遠隔操作式のレリースワイヤが挿通される枝管34を配設し、そしてその直落しナットの上下端には、上下対称の外向きフランジ32を形成する。
本体31の内周面全体は、内ネジ33が刻設され、上外向きフランジ32aによって直落しナット3を排水口金具12に螺合することにより、排水口金具12とで浴槽1の排水口10を挟持締着する。また、下外向きフランジ32bには、該下外向きフランジと防水パン2の排水口20とで、水密性のための押圧接続がされる軟質パッキン4を介在し、該軟質パッキンの上端部が被抱保持される。
The straight drop nut 3 has a straight cylindrical body 31 that is vertically symmetric, a branch pipe 34 through which a remote-controlled release wire is inserted is disposed at an intermediate position thereof, and upper and lower ends of the straight drop nut are A vertically symmetric outward flange 32 is formed.
The entire inner peripheral surface of the main body 31 is engraved with an internal thread 33, and is directly dropped by an upward and outward flange 32a, and the nut 3 is screwed into the drain opening metal fitting 12, so that the drain opening of the bathtub 1 is connected to the drain opening metal fitting 12. 10 is clamped. In addition, a soft packing 4 that is pressed and connected for watertightness is interposed between the downward outward flange 32b and the drain 20 of the waterproof pan 2 at the downward outward flange 32b, and the upper end of the soft packing is Be held and held.

軟質パッキン4は、直落しナット3と防水パン2の排水口20とに接続する、押し潰されることによって水密性が確保されるものであって、一般的には、ゴム製蛇腹状体である。上端には、直落しナット3の下外向きフランジ32bが被抱保持される大径の断面コ字型環状端部41を形成し、下端には、防水パン2の排水口20に差込まれる小径の筒状差込端部42を形成している。  The soft packing 4 is connected directly to the nut 3 and the drain opening 20 of the waterproof pan 2 and is secured by being crushed. Generally, the soft packing 4 is a rubber bellows-like body. . A large-diameter U-shaped annular end 41 is formed at the upper end to hold the downwardly-facing flange 32b of the nut 3 directly downward, and is inserted into the drain 20 of the waterproof pan 2 at the lower end. A small-diameter cylindrical insertion end portion 42 is formed.

防水パン2は、その排水口20の下方向には、排水トラップ又は排水トラップ接続管21が設置され、該排水トラップ又は排水トラップ接続管を被蓋するカバー22には排水口20が形成されている。  The waterproof pan 2 is provided with a drain trap or drain trap connecting pipe 21 below the drain port 20, and the drain port 20 is formed in a cover 22 that covers the drain trap or drain trap connecting pipe. Yes.

遠隔操作式排水栓装置11は、浴槽1の排水口10を開閉する排水栓111と、直落しナット3の枝管34より挿通させて、浴槽1を直落しナット3とで挟持する排水口金具12に支持部材112をもって支持する作動部113と、該作動部へ接続されるレリースワイヤ114と、操作部(図示せず)とでなり、操作部よりの操作がレリースワイヤ114による伝達で、排水栓111が昇降される。  The remote-operated drain plug device 11 includes a drain plug 111 that opens / closes the drain port 10 of the bathtub 1 and a branch pipe 34 of the direct drop nut 3, and the drain port fitting that directly drops the bathtub 1 and holds it between the nut 3. 12 with a support member 112 supported by a support member 112, a release wire 114 connected to the operation unit, and an operation unit (not shown). The stopper 111 is moved up and down.

遠隔操作式排水栓装置11を備えた浴槽の排水口10と防水パンの排水口20とが接続される排水接続構造において、該排水接続構造が、低床仕様、バリアフリー対策によって、浴槽底部と防水パン2との空間の高さを抑えられ、その高さが抑制されることになる。
そこで、浴槽の排水口10と防水パンの排水口20とが接続される排水接続構造に、接続継手の機能を、浴槽1が排水口金具12とで挟持締着される直落しナット3に担せ、部品点数を省略することになり、それでいて、高さ嵩を減少させ、その上、直落しナット3を防水パン2の排水口20へ接続する設置誤差が調整される調整材として、軟質パッキン4が採用され、該軟質パッキンを直落しナット3の下外向きパッキン32bに簡単且つ容易に被抱挟持し、取付けることができるような構造にしているので、作業の困難性がなく、短時間での施工ができる。
In the drainage connection structure in which the drainage port 10 of the bathtub equipped with the remote-operated drain plug device 11 and the drainage port 20 of the waterproof pan are connected, the drainage connection structure is connected to the bottom of the bathtub by a low floor specification and a barrier-free measure. The height of the space with the waterproof pan 2 is suppressed, and the height is suppressed.
Therefore, the drainage connection structure in which the drainage port 10 of the bathtub and the drainage port 20 of the waterproof pan are connected has the function of a connection joint, and bears the direct drop nut 3 in which the bathtub 1 is clamped and fastened with the drainage fitting 12. The number of parts is omitted, and yet the height packing is reduced, and in addition, the soft packing is used as an adjustment material for adjusting the installation error for connecting the nut 3 directly to the drain outlet 20 of the waterproof pan 2. 4 is adopted, and the structure is such that the soft packing is directly dropped and can be clamped and attached to the downwardly outward packing 32b of the nut 3 easily and easily, so that there is no difficulty in work and the time is short. Can be installed in.

そして、排水口金具12と直落しナット3とで挟持締着された浴槽1は、排水口金具12に遠隔操作式排水栓装置11が備えられ、直落しナット3には、軟質パッキン4を容易に取付け、これらが取付けられた浴槽1は、軟質パッキン4の下端の小径筒状差込端部を防水パンの排水口20に簡単且つ容易に差込むことができることになって、設置作業が熟練者でなくても短時間に終了させることができる。  The bathtub 1 clamped and clamped between the drain fitting 12 and the drop nut 3 is provided with a remote-operated drain plug device 11 on the drain fitting 12, and the soft packing 4 is easily attached to the drop nut 3. The bathtub 1 to which these are attached can easily and easily insert the small-diameter cylindrical insertion end at the lower end of the soft packing 4 into the drainage port 20 of the waterproof pan, so that the installation work is skillful. Even if it is not a person, it can be completed in a short time.

なお、浴槽1を排水口金具12と、直落しナット3とで挟持締着するに当って、直落しナット3には方向性がないのでどちらの方向からも螺合することができ、作業が簡素化でき、また更に、上下両端にある外向きフランジ32が、上下対称であるので、軟質パッキン4の直落しナット3への取付けに交換性があるので、考慮なくできる。
よって、作業が簡単且つ容易で、効率良く、時間短縮することになる。
When the bathtub 1 is clamped and fastened with the drain fitting 12 and the direct drop nut 3, the direct drop nut 3 has no direction and can be screwed from either direction. Further, since the outward flanges 32 at the upper and lower ends are symmetrical in the vertical direction, the soft packing 4 can be attached to the direct drop nut 3 without being considered.
Therefore, the operation is simple and easy, efficient, and time saving.

図2、図3、及び図4で示す如く、レリースワイヤを挿通させる枝管34が、直筒状の本体31の上下対称の中間位置で直落しナット3の本体31の筒壁上に、その軸心より軸が離れた位置にあるようにした場合には、特に、本体31の筒壁上に配設された枝管34が、その軸心を本体31の筒壁接線上とし、蝸牛状とされた場合には、枝管34から挿通されたレリースワイヤが枝管34の挿通孔35を経て、本体31内壁面を沿って旋回した上で遠隔操作式排水栓装置11の作動部113に接続されるので、作動部113への接続のための鋭い屈曲が逃避されることになって、レリースワイヤに曲げ負担が軽減され、耐久性と、良い作動性を得ることができることになる。
そして、直落しナットの本体31を上下反転することによって、枝管34の本体31に対する配設方向が逆転され、直落しナット3の本体31へ挿通され、旋回するようにされるレリースワイヤの挿通方向を逆転させることができ、直落しナット3を単に反転するのみで、レリースワイヤの挿通方向を変更できるので、施工が効果的である。
なお、枝管34には、水密性を保持させるための挿通ブッシュ5が嵌着され、レリースワイヤが挟持挿通されている。
As shown in FIGS. 2, 3, and 4, the branch pipe 34 through which the release wire is inserted is dropped directly at a vertically symmetrical intermediate position of the straight cylindrical main body 31, and the shaft is placed on the cylindrical wall of the main body 31 of the nut 3. In the case where the axis is located away from the center, in particular, the branch pipe 34 disposed on the cylindrical wall of the main body 31 has its axial center on the cylindrical wall tangent of the main body 31 and has a cochlear shape. In this case, the release wire inserted from the branch pipe 34 is turned along the inner wall surface of the main body 31 through the insertion hole 35 of the branch pipe 34 and then connected to the operating portion 113 of the remote-operated drain plug device 11. Therefore, a sharp bend for connection to the operating portion 113 is escaped, and the bending burden on the release wire is reduced, so that durability and good operability can be obtained.
Then, by turning the main body 31 of the direct drop nut upside down, the arrangement direction of the branch pipe 34 with respect to the main body 31 is reversed, and the release wire inserted into the main body 31 of the direct drop nut 3 and turned is inserted. The direction can be reversed, and the installation direction is effective since the insertion direction of the release wire can be changed by simply reversing the nut 3 directly.
The branch pipe 34 is fitted with an insertion bush 5 for maintaining watertightness, and a release wire is sandwiched and inserted.
