Description

本発明は、浴槽や洗面ボウルなどの水槽の排水口を開閉するのに使用される遠隔操作式の排水栓装置に関する。   The present invention relates to a remote-operated drain plug device used to open and close a drain of a water tank such as a bathtub or a wash bowl.

従来、遠隔操作式の排水栓装置では、その操作部を浴槽のリム面などの取付対象部に取り付ける際に、操作部の上下動をガイドする貫通孔を有するフランジ部材とフランジ部材の外周に螺合するナットとで浴槽を挟持するように固定していた。そして、このフランジ部材からの貫通孔に水が浸入するのを防止するために、フランジ部材のフランジと浴槽との間に平パッキンを設けていた。しかし、平パッキンがフランジの回りに露出するので、見栄えが悪いという問題があった。   Conventionally, in a remote-operated drain plug device, when the operation part is attached to an attachment target part such as a rim surface of a bathtub, a flange member having a through hole for guiding the vertical movement of the operation part and a screw thread around the outer periphery of the flange member are provided. It was fixed so that the bathtub was clamped with the mating nut. In order to prevent water from entering the through hole from the flange member, a flat packing is provided between the flange of the flange member and the bathtub. However, since the flat packing is exposed around the flange, there is a problem that it does not look good.

特開2008−248687号公報JP 2008-248687 A

そこで、この平パッキンを浴槽とナットの間で挟みこんで潰す構造が考えられる。しかし、この構造では締め付け時のすべり性を確保するため、ナットと平パッキンの間にすべりワッシャを配置する必要があり、コストがかかっていた。また、フランジを回して締付ける構造とした場合、フランジ部材のフランジの底面が浴槽のリム面に接触してすべりつつ締付けられることになる。このとき、フランジ部材の表面を装飾するためにステンレス等の金属部材をカシメて被膜している場合、金属部材の端面が浴槽のリム面に当たった状態でフランジを回すと、浴槽のリム面に傷が付く可能性がある。また、浴槽のリム面に金属部材の端面が当たると、その当たり方によって締め付けトルクにばらつきが出て、平パッキンを所望のトルクで締め付けられない可能性もある。   Therefore, a structure in which this flat packing is sandwiched between a bathtub and a nut is considered. However, in this structure, it is necessary to arrange a sliding washer between the nut and the flat packing in order to secure the sliding property at the time of tightening, which is costly. Moreover, when it is set as the structure tightened by rotating a flange, the bottom face of the flange of a flange member will contact with the rim surface of a bathtub, and will be tightened while sliding. At this time, when a metal member such as stainless steel is caulked and coated to decorate the surface of the flange member, if the flange is turned with the end surface of the metal member hitting the rim surface of the bathtub, the rim surface of the bathtub There is a possibility of scratching. Further, when the end surface of the metal member hits the rim surface of the bathtub, there is a possibility that the tightening torque varies depending on how it hits, and the flat packing cannot be tightened with a desired torque.

そこで、本発明は、遠隔操作式排水栓装置の操作部を、取付対象部に傷をつけることなく、確実に取り付けることを目的とする。   Then, an object of this invention is to attach the operation part of a remote-control type drain plug apparatus reliably, without damaging an attachment object part.

上記の課題を解決するために成された、請求項1の発明は、水槽に設けられた排水口を閉じる排水栓蓋を、操作ボタンの操作によってレリースワイヤを介して昇降させて前記排水口を開閉する遠隔操作式排水栓装置の操作部構造において、前記操作ボタンが取り付けられる取付対象部に形成された貫通孔に表面側から挿入され、内部に前記操作ボタンを進退可能な案内面を有し、周囲に雄ネジが設けられた円筒部と、当該円筒部の上部に外方に広がるように形成されて底面が前記取付対象部に当接するフランジと、を有する樹脂製のフランジ部材と、前記取付対象部の裏面側から前記円筒部の雄ネジに螺合される雌ネジが設けられて、前記フランジと共に前記取付対象部を挟持する締付ナットと、を備え、前記フランジ部材の前記円筒部の内周から前記フランジにかけての表面を金属製の被覆部材で、前記フランジの底面よりも高い位置までを被覆することを特徴とする遠隔操作式排水栓装置の操作部構造である。   In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that a drain plug lid for closing a drain port provided in a water tank is moved up and down via a release wire by operating an operation button so that the drain port is opened. In the operation part structure of the remote-operated drain plug device that opens and closes, it has a guide surface that is inserted from the surface side into a through-hole formed in the attachment target part to which the operation button is attached, and in which the operation button can be advanced and retracted A flange portion made of a resin having a cylindrical portion provided with a male screw around the periphery, and a flange formed so as to spread outward at an upper portion of the cylindrical portion and having a bottom surface abutting the attachment target portion, A tightening nut that is provided with a female screw that is screwed into a male screw of the cylindrical portion from the back surface side of the mounting target portion, and clamps the mounting target portion together with the flange; and the cylindrical portion of the flange member Of In the covering member surface of the metal of toward the flange from it an operation section structure of the remote controlled discharge valve device according to claim covering a to a position higher than the bottom surface of the flange.

これによれば、遠隔操作式排水栓装置の操作部のフランジが金属製の被覆部材で被覆されるので、フランジを塗装したり、金属メッキした場合よりも、高級感のある外観にすることができ、意匠性が向上する。
また、フランジの外周側における被覆部材の端部が、フランジの底面に達しないように、フランジの底面よりも高い位置までを被覆するので、金属製の被覆部材が取付対象部に接触しない。よって、締付ナットにフランジ部材を締め付ける際に、フランジ部材を回しても被覆部材の端部で取付対象部を傷つけることがない。
According to this, since the flange of the operation part of the remote control type drain plug device is covered with the metal covering member, it is possible to make the appearance more luxurious than when the flange is painted or metal-plated. And the design is improved.
Moreover, since the edge part of the coating | coated member in the outer peripheral side of a flange covers even a position higher than the bottom face of a flange so that it may not reach the bottom face of a flange, a metal coating | coated member does not contact an attachment object part. Therefore, when the flange member is tightened to the tightening nut, the attachment target portion is not damaged at the end portion of the covering member even if the flange member is turned.

また、請求項2の発明は、前記フランジの外周下部に、前記被覆部材の厚みよりも大きい凹部を形成し、前記凹部に前記被覆部材の端部を収めたことを特徴とする請求項1記載の遠隔操作式排水栓装置の操作部構造である。   The invention according to claim 2 is characterized in that a concave portion larger than the thickness of the covering member is formed in the lower peripheral portion of the flange, and an end portion of the covering member is accommodated in the concave portion. It is an operation part structure of the remote-control type drain plug device.

これによれば、フランジの外周側における被覆部材の端部が、フランジの外周株の凹部に収められるので、被覆部材の端部を確実に取付対象部から離間させることが可能となる。   According to this, since the edge part of the coating | coated member in the outer peripheral side of a flange is stored in the recessed part of the outer periphery strain | stump | stock of a flange, it becomes possible to space apart the edge part of a coating | coated member from an attachment object part reliably.

本発明によれば、遠隔操作式排水栓装置の操作部を、取付対象部に傷をつけることなく、確実に取り付けることが可能となる。   ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to attach reliably the operation part of a remote-control type drain plug apparatus, without damaging an attachment object part.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic view showing a drain plug device according to an embodiment of the present invention.
The drain plug device 100 includes a drain plug portion 100A attached to a drain port 210 provided in the bathtub 200 (water tank) and an operation portion attached to a through hole 221 (see FIG. 3) formed in the rim surface 220 of the bathtub 200. 100B, and is a remote-operated drain plug device in which a drain plug portion 100A and an operation portion 100B are connected by a release wire 160.

次に、操作部100Bについて説明する。
図2は排水栓装置の操作部を示す側面図、図3は操作部の中央縦断面図、図4は操作部の部分拡大断面図、図5は操作部の分解図である。
操作部100Bは、外周面に雄ネジ113が形成された円筒部111の上端部に外向きのフランジ112を設けたフランジ部材110と、フランジ部材110の雄ネジ113に螺合する雌ネジ121を有する締付ナット120と、レリースワイヤ160の他端に設けられた機構部162を保持してフランジ部材110の円筒部111の下端に下方から接続される接続管130と、接続管130を締付ナット120に取り付ける接続管用接続具140と、フランジ部材110の円筒部111の内部に進退可能に配設された操作ボタン150と、を備えている。これらのフランジ部材110、締付ナット120、接続管130、接続管用接続具140、操作ボタン150は、いずれも樹脂製部材である。なお、フランジ部材110と操作ボタン150は、高級感を出すために、それぞれ樹脂製部材の表面に薄肉の金属製部材を被覆して化粧している。
Next, the operation unit 100B will be described.
2 is a side view showing an operation part of the drain plug device, FIG. 3 is a central longitudinal sectional view of the operation part, FIG. 4 is a partially enlarged sectional view of the operation part, and FIG. 5 is an exploded view of the operation part.
The operation unit 100B includes a flange member 110 provided with an outward flange 112 at an upper end portion of a cylindrical portion 111 having a male screw 113 formed on the outer peripheral surface, and a female screw 121 that is screwed to the male screw 113 of the flange member 110. A fastening nut 120 having a connection portion 130 that holds a mechanism portion 162 provided at the other end of the release wire 160 and is connected to the lower end of the cylindrical portion 111 of the flange member 110 from below; A connecting pipe connector 140 to be attached to the nut 120 and an operation button 150 disposed in the cylindrical portion 111 of the flange member 110 so as to be able to advance and retract are provided. The flange member 110, the tightening nut 120, the connection pipe 130, the connection pipe connector 140, and the operation button 150 are all resin members. The flange member 110 and the operation button 150 are each made up by covering a thin metal member on the surface of the resin member in order to give a high-class feeling.

フランジ部材110は、前述したように、外周面に雄ネジ113が形成された円筒部111の上端部に外向きに広がるように形成されたフランジ112を備えている。フランジ112の底面は、浴槽200のリム面220に当接している。このフランジ部材110の円筒部111の内周側上部からフランジ112にかけての表面を、金属製の被覆部材115で被覆している。この被覆部材115は、例えば光沢を帯びたステンレスなどの金属を薄板状に加工したものであり、フランジ部材110に対してカシメることによって一体化されている。被覆部材115の外周側の端部は、フランジ112の底面よりもやや高い位置までを被覆している。すなわち、被覆部材115の端部は、浴槽200のリム面220には当接していない。より具体的には、フランジ112の外周下部には、被覆部材115の端部が収まる凹部116が形成されている。凹部116におけるフランジ112の下面と浴槽200のリム面220との寸法の最小値は、被覆部材115の厚みよりも大きくとられている。これにより、フランジ112にカシメられた被覆部材115は、浴槽200のリム面220に当接することがない。   As described above, the flange member 110 includes the flange 112 formed so as to spread outward at the upper end portion of the cylindrical portion 111 in which the external thread 113 is formed on the outer peripheral surface. The bottom surface of the flange 112 is in contact with the rim surface 220 of the bathtub 200. The surface from the upper part on the inner peripheral side of the cylindrical portion 111 of the flange member 110 to the flange 112 is covered with a metal covering member 115. The covering member 115 is obtained by processing a metal such as glossy stainless steel into a thin plate shape, and is integrated with the flange member 110 by caulking. The end portion on the outer peripheral side of the covering member 115 covers up to a position slightly higher than the bottom surface of the flange 112. That is, the end portion of the covering member 115 is not in contact with the rim surface 220 of the bathtub 200. More specifically, a concave portion 116 in which the end portion of the covering member 115 is received is formed in the lower outer periphery of the flange 112. The minimum value of the dimension between the lower surface of the flange 112 and the rim surface 220 of the bathtub 200 in the recess 116 is set larger than the thickness of the covering member 115. Thereby, the covering member 115 crimped to the flange 112 does not contact the rim surface 220 of the bathtub 200.

このフランジ部材110は浴槽200のリム面220の表面側から貫通孔221に挿通される。締付ナット120は、浴槽200のリム面220の裏面側から、雌ネジ121をフランジ部材110の雄ネジ113に螺合させる。雌ネジ121を雄ネジ113に締め付けて、フランジ部材110のフランジ112と締付ナット120とで浴槽200のリム面220を挟持する。そして、フランジ部材110の円筒部111の内周が、操作ボタン150を進退可能に支える案内面114となる。これにより、フランジ部材110と締付ナット120とが、浴槽200のリム面220に設けた貫通孔221に対して操作ボタン150の進退をガイドする操作部ガイド部Aとなる。   The flange member 110 is inserted into the through hole 221 from the surface side of the rim surface 220 of the bathtub 200. The tightening nut 120 screws the female screw 121 into the male screw 113 of the flange member 110 from the back side of the rim surface 220 of the bathtub 200. The female screw 121 is fastened to the male screw 113, and the rim surface 220 of the bathtub 200 is held between the flange 112 of the flange member 110 and the fastening nut 120. And the inner periphery of the cylindrical part 111 of the flange member 110 becomes the guide surface 114 which supports the operation button 150 so that advancement / retraction is possible. Accordingly, the flange member 110 and the tightening nut 120 serve as an operation portion guide portion A that guides the advancement and retreat of the operation button 150 with respect to the through hole 221 provided in the rim surface 220 of the bathtub 200.

ここで、フランジ部材110と締付ナット120との螺合は、締付ナット120を工具あるいは手で押さえて仮固定した状態で、フランジ部材110を別の工具で回すことによって行われる。そのため、フランジ部材110は、浴槽200のリム面220の上で旋回することになる。ところが、フランジ部材110のフランジ112は、被覆部材115がフランジ112の底面よりもやや高い位置までを被覆しているので、フランジ112の底面まで被覆部材115が達していない。そのため、リム面220の上でフランジ部材110を回しても、被覆部材115はリム面220に接触しないから、被覆部材115の端部でリム面220を大きく傷つけることはない。   Here, the screwing of the flange member 110 and the tightening nut 120 is performed by rotating the flange member 110 with another tool in a state where the tightening nut 120 is temporarily fixed by being pressed by a tool or a hand. Therefore, the flange member 110 turns on the rim surface 220 of the bathtub 200. However, since the covering member 115 covers the flange 112 of the flange member 110 up to a position slightly higher than the bottom surface of the flange 112, the covering member 115 does not reach the bottom surface of the flange 112. Therefore, even if the flange member 110 is rotated on the rim surface 220, the covering member 115 does not contact the rim surface 220, so that the rim surface 220 is not greatly damaged at the end of the covering member 115.

締付ナット120は、その外周面の下方に、後述するガイド溝122を複数設けている。また、締付ナット120の下部に、接続管130の上端部が挿入可能な凹部123を形成している。   The tightening nut 120 is provided with a plurality of guide grooves 122 to be described later below the outer peripheral surface thereof. Further, a recess 123 into which the upper end portion of the connection pipe 130 can be inserted is formed in the lower portion of the tightening nut 120.

接続管130は、下端部にレリースワイヤ160の周囲を囲うホース170が接続され、上端部を操作部ガイド部Aに接続している。また、接続管130の内部に、機構部162を保持する保持部131を形成している。また、接続管130は、上端部を外向きに突出させた突出部132とし、その外周側面に、Oリング133を嵌める溝134を設けている。このOリング133は、接続管130が操作部ガイド部Aに接続されると、接続管130の上端部が締付ナット120の凹部123に挿入されて、締付ナット120の凹部123の内周面に密接してシールする。   The connecting pipe 130 has a lower end connected to a hose 170 surrounding the release wire 160, and an upper end connected to the operation unit guide A. In addition, a holding portion 131 that holds the mechanism portion 162 is formed inside the connecting pipe 130. Further, the connecting pipe 130 has a protruding portion 132 with an upper end protruding outward, and a groove 134 for fitting the O-ring 133 is provided on the outer peripheral side surface thereof. When the connecting pipe 130 is connected to the operation portion guide part A, the O-ring 133 is inserted into the recess 123 of the tightening nut 120 when the connecting pipe 130 is connected to the inner periphery of the recess 123 of the tightening nut 120. Seal closely to the surface.

接続管接続具140は、接続管130の上部寄りの端部に回転可能に設けられている。具体的には、接続管130の上部の周囲に形成した浅溝部135に、接続管接続具140を部分的に係合させて、接続管接続具140を浅溝部135に沿って回転可能にしている。また、接続管接続具140を浅溝部135に係合させた状態で、接続管接続具140の水平上面が接続管130の突出部132の下面に接する。そして、接続管接続具140の内周部の上方に、後述する突起141を複数設けている。   The connection pipe connector 140 is rotatably provided at the end near the upper part of the connection pipe 130. Specifically, the connection tube connector 140 is partially engaged with the shallow groove portion 135 formed around the upper portion of the connection tube 130 so that the connection tube connection device 140 can be rotated along the shallow groove portion 135. Yes. In addition, the horizontal upper surface of the connecting pipe connector 140 is in contact with the lower surface of the protruding portion 132 of the connecting pipe 130 in a state where the connecting pipe connector 140 is engaged with the shallow groove portion 135. A plurality of protrusions 141 to be described later are provided above the inner periphery of the connection pipe connector 140.

接続管130を操作部ガイド部Aに接続する際には、接続管130の上端を操作部ガイド部Aに近づけた状態で操作部接続具140を回して、突起141を前述した締付ナット120のガイド溝122に挿入し、さらに操作部接続具140を回し続けて突起141をガイド溝122のロック位置122cまで到達させて、接続管130の接続は完了となる。   When connecting the connecting pipe 130 to the operating section guide section A, the operating section connecting tool 140 is turned in a state where the upper end of the connecting pipe 130 is close to the operating section guide section A, and the protrusion 141 is connected to the above-described tightening nut 120. Then, the operation part connector 140 is further rotated to reach the projection 141 to the lock position 122c of the guide groove 122, and the connection of the connection pipe 130 is completed.

操作ボタン150は、機構部162の内部から操作ボタン側に突き出たロッド163の先端に装着される。操作ボタン150を押すたびに、操作ボタン150を押す力がロッド163から機構部162に伝わり、レリースワイヤ160を介して排水栓蓋190を昇降する。   The operation button 150 is attached to the tip of a rod 163 that protrudes from the inside of the mechanism portion 162 toward the operation button. Each time the operation button 150 is pressed, a force for pressing the operation button 150 is transmitted from the rod 163 to the mechanism portion 162, and the drain plug lid 190 is moved up and down via the release wire 160.

機構部162は、操作ボタン150を押すたびにロッド163が機構部162内に押込まれて、機構部162内でレリースワイヤ160のインナーワイヤを押し込んで、操作ボタン150の進退動作をレリースワイヤ160に伝えるように機能する。また、使用者が操作ボタン150から手を離すと、押込まれたロッド163を上昇させる復帰バネ(図示せず)を内蔵して、操作ボタン150を上昇させるように機能する。さらに、本実施形態では、機構部162の内部にラッチ機構(図示せず)を内蔵させ、押しボタン150を押すたびに、高い位置と低い位置とに交互に押しボタン150が位置するようにして、排水栓蓋190が排水口210を閉じる位置と排水口210を開く位置とに保持するようにしている。   Whenever the operation unit 150 is pressed, the mechanism unit 162 pushes the rod 163 into the mechanism unit 162 and presses the inner wire of the release wire 160 in the mechanism unit 162, thereby moving the operation button 150 forward and backward to the release wire 160. It functions to communicate. Further, when the user releases the operation button 150, a return spring (not shown) that raises the pushed rod 163 is built in and functions to raise the operation button 150. Further, in this embodiment, a latch mechanism (not shown) is built in the mechanism unit 162 so that the push button 150 is alternately positioned at a high position and a low position each time the push button 150 is pressed. The drain plug lid 190 is held at a position where the drain port 210 is closed and a position where the drain port 210 is opened.

Next, a structure for connecting the connecting pipe 140 to the operation section guide section A will be described.
6 is a side view showing a state in which the operation part is attached to the rim part of the bathtub, FIG. 7 is a central longitudinal sectional view showing the operation part in the same state as FIG. 6, and FIG. 8 is a tightening to attach the flange member to the rim part of the bathtub It is a side view which shows a nut.

前述したように、接続管用接続具140は、その内周部の上方に突起141を設けている。本実施形態では、90度間隔で4個の突起141を設けている。   As described above, the connection pipe connector 140 is provided with the protrusion 141 above the inner periphery thereof. In the present embodiment, four protrusions 141 are provided at intervals of 90 degrees.

また、操作部ガイド部Aの一部を構成する締付ナット120は、その外周部に突起141を差し込み可能なガイド溝122を、突起141と同じく4個設けている。このガイド溝122は、締付ナット120の外周面を内方に凹ませて形成している。このガイド溝120の凹みは、突起141がガイド溝120から外れて空回りしないように適度な深さになっている。また、ガイド溝122の手前を締付ナット120の下面に開放して、その解放端から突起141を挿入するようにされている。   Further, the tightening nut 120 that constitutes a part of the operation portion guide portion A is provided with four guide grooves 122 into which the protrusions 141 can be inserted on the outer periphery thereof, like the protrusions 141. The guide groove 122 is formed by recessing the outer peripheral surface of the tightening nut 120 inward. The recess of the guide groove 120 has an appropriate depth so that the protrusion 141 does not come out of the guide groove 120 and does not idle. Further, the front of the guide groove 122 is opened to the lower surface of the tightening nut 120, and the protrusion 141 is inserted from the open end.

ガイド溝122の奥には、差し込まれた突起141を動かぬように拘束するロック部が設けられている。本実施形態においては、このロック部は、ガイド溝122の底面122eを部分的に浅くする段部122aで構成している。接続管接続具140をロックする際には、接続管接続具140を回して突起141の頂点が段部122aを乗り越えるように力をかけて接続管接続具140を回転させることによって、突起141をロック位置122cに到達させる。
また、ガイド溝122の解放端から段部122aの間に、ガイド溝122に受け入れた突起141を斜め上向きに案内する傾斜ガイド部122bを設けている。
さらに、ガイド溝122には、脱落防止部124を設けている。本実施形態では、この脱落防止部124は、段部122aより奥側、すなわちガイド溝122のロック位置122cの下部に、外側に突出させた突出壁を設けることにより、突起141がガイド溝122から外れないように構成している。これにより、接続管130が左右に傾くような方向に力が加わった場合でも、この突出壁が、突起141のガイド溝122へのかかり代を大きくするように働くので、接続管130が操作部ガイド部Aから外れるのを防止することができる。
A lock portion that restrains the inserted protrusion 141 so as not to move is provided at the back of the guide groove 122. In the present embodiment, the lock portion is constituted by a step portion 122a that partially shallows the bottom surface 122e of the guide groove 122. When locking the connecting pipe connector 140, the connecting pipe connector 140 is rotated so that the apex of the protrusion 141 is moved over the stepped portion 122 a by rotating the connecting pipe connector 140. The lock position 122c is reached.
Further, an inclined guide portion 122b for guiding the protrusion 141 received in the guide groove 122 obliquely upward is provided between the open end of the guide groove 122 and the stepped portion 122a.
Further, a drop prevention portion 124 is provided in the guide groove 122. In the present embodiment, the drop-off prevention portion 124 is provided with a protruding wall that protrudes outward from the step portion 122 a, that is, below the lock position 122 c of the guide groove 122, so that the protrusion 141 is removed from the guide groove 122. It is configured not to come off. As a result, even when a force is applied in a direction in which the connecting pipe 130 is tilted to the left and right, the protruding wall works to increase the amount of protrusion of the protrusion 141 on the guide groove 122. It can prevent coming off from the guide part A.

接続管130を操作部ガイド部Aに接続する際には、まず、接続管130の上端を操作部ガイド部Aに近づけた状態で操作部接続具140を回して、突起141を前述した締付ナット120のガイド溝122に挿入する。次いで、操作部接続具140を回し続けて、突起141をガイド溝122の傾斜ガイド部122b内を移動させることによって接続管接続具140を上方に移動させて接続管130の上端部を締付ナット120の下面に設けた凹部123に徐々に挿入させる。この際、接続管130に取り付けたOリング133も接続管接続具140を回すことによって軽い力で凹部123に挿入される。そして、さらに操作部接続具140を回して、突起141をガイド溝122のロック位置122cまで到達させて、接続管130の接続は完了となる。   When connecting the connection pipe 130 to the operation section guide section A, first, the operation section connecting tool 140 is turned with the upper end of the connection pipe 130 being close to the operation section guide section A, and the protrusion 141 is tightened as described above. Insert into the guide groove 122 of the nut 120. Subsequently, the operation unit connector 140 is continuously rotated, and the projection 141 is moved in the inclined guide portion 122b of the guide groove 122 to move the connection tube connector 140 upward, and the upper end of the connection tube 130 is tightened with the tightening nut. It is made to insert gradually in the recessed part 123 provided in the lower surface of 120. At this time, the O-ring 133 attached to the connection pipe 130 is also inserted into the recess 123 with a light force by turning the connection pipe connector 140. Then, the operation unit connector 140 is further rotated so that the protrusion 141 reaches the lock position 122c of the guide groove 122, and the connection of the connection pipe 130 is completed.

このように、本実施形態では、接続管130に回転可能に付設されている接続管接続具140を少し回すだけで、操作部ガイド部Aに接続管130を接続することができる。そのため、従来のように、着脱可能なロック部材の装着ミスによって接続管が接続不良となることはない。また、接続管接続具140は、締め込む量が大きい袋ナットではないから、接続管接続具140を少し回すだけで接続できるので、接続作業も簡単であり、接続管接続具140の作業ミスも起こりにくい。すなわち、簡単な作業で操作部ガイド部Aに接続管130を確実に取り付けることができるので、接続管130の取付け不良による不具合を無くすことができる。   Thus, in the present embodiment, the connection pipe 130 can be connected to the operation section guide portion A by slightly turning the connection pipe connector 140 attached to the connection pipe 130 in a rotatable manner. Therefore, the connection pipe does not become poorly connected due to a mounting error of the detachable lock member as in the conventional case. In addition, since the connecting pipe connector 140 is not a cap nut with a large amount to be tightened, it can be connected by turning the connecting pipe connector 140 a little. Hard to happen. That is, since the connection pipe 130 can be reliably attached to the operation section guide part A by a simple operation, problems due to poor attachment of the connection pipe 130 can be eliminated.

また、ガイド溝122の奥に、突起141をロック位置122cに拘束する位置決め用の段部122aを形成したことにより、接続管接続具140が自然に抜けるのを防止できる。   Further, since the positioning step 122a that restrains the protrusion 141 at the lock position 122c is formed in the back of the guide groove 122, it is possible to prevent the connecting pipe connector 140 from coming off naturally.

さらに、突起141がロック位置122cに到達して接続管130が操作部ガイド部Aに接続された状態で、例えば、ホース170が斜めに引っ張られるなどして接続管130を左右に傾ける方向の力が働いたとしても、ガイド溝122から突起141が外れるのを脱落防止部124が防止するので、接続管130をより強固に接続することができる。   Further, in a state where the projection 141 reaches the lock position 122c and the connection pipe 130 is connected to the operation section guide part A, for example, a force in a direction in which the connection pipe 130 is tilted left and right by pulling the hose 170 obliquely or the like. Even if this works, the drop-off prevention part 124 prevents the protrusion 141 from coming off the guide groove 122, so that the connecting pipe 130 can be connected more firmly.

また、締付ナット120にガイド溝122を設けたことにより、操作部ガイド部Aを予め浴槽200のリム面220に取り付けた際に占める領域を小さく抑えることができる。そのため、浴槽200のリム面220の下方の作業空間を大きく確保することができ、例えば、浴槽200の裏側に被るような壁パネルの施工の作業性を高めることができる。   Further, by providing the guide nut 122 in the tightening nut 120, it is possible to reduce the area occupied when the operation portion guide portion A is previously attached to the rim surface 220 of the bathtub 200. Therefore, a large work space below the rim surface 220 of the bathtub 200 can be secured, and for example, workability of construction of a wall panel that covers the back side of the bathtub 200 can be improved.

さらに、ガイド溝122は、接続管130が操作部ガイド部Aに徐々に挿入させる傾斜ガイド部122bを有し、突起141を傾斜ガイド部122bで案内しつつ接続管130を操作部ガイド部Aに徐々に挿入することによって、接続管130に設けたOリング133を、操作部ガイド部Aと接続管130との間に配設させるようにした。これにより、接続管用接続具140を回転させて接続管接続具140を徐々に操作部ガイド部A内に挿入させる動きを利用して、操作部ガイド部Aと接続管130の間にOリング133を配設するので、Oリング133を操作部ガイド部Aと接続管130の間に楽に押し込むことが可能となる。   Further, the guide groove 122 has an inclined guide portion 122b that allows the connecting tube 130 to be gradually inserted into the operation portion guide portion A. The guide tube 122 is guided to the operation portion guide portion A while the protrusion 141 is guided by the inclined guide portion 122b. By gradually inserting, the O-ring 133 provided in the connection pipe 130 is disposed between the operation portion guide part A and the connection pipe 130. Accordingly, the O-ring 133 is interposed between the operating portion guide portion A and the connecting tube 130 by utilizing the movement of rotating the connecting tube connector 140 and gradually inserting the connecting tube connector 140 into the operating portion guide portion A. Therefore, the O-ring 133 can be easily pushed between the operation portion guide portion A and the connection pipe 130.

次に、前述した実施形態の変形例について説明する。
図9は締付ナットの変形例を示す側面図である。
この変形例では、図8の実施形態から、ガイド溝122の傾斜ガイド部122bをなくして、代わりに垂直ガイド部122dを設けている。
この例では、接続管130の接続の際には、接続管接続具140を回して接続管接続具140の突起141の位置をガイド溝122に一致させて、接続管接続具140を垂直ガイド部122dに沿って上向きに押し込み、その後接続管接続具140を再度回して突起141をロック位置122cに到達させる。
これによれば、接続管130を徐々に締付ナット120の凹部123に挿入されることはないが、前述した実施形態とほぼ同じ作用効果を奏する。
Next, a modified example of the above-described embodiment will be described.
FIG. 9 is a side view showing a modified example of the tightening nut.
In this modification, the inclined guide portion 122b of the guide groove 122 is eliminated from the embodiment of FIG. 8, and a vertical guide portion 122d is provided instead.
In this example, when connecting the connection pipe 130, the connection pipe connection tool 140 is turned to match the position of the protrusion 141 of the connection pipe connection tool 140 with the guide groove 122, so that the connection pipe connection tool 140 is moved to the vertical guide portion. After pushing upward along 122d, the connecting pipe connector 140 is rotated again to cause the protrusion 141 to reach the lock position 122c.
According to this, the connecting pipe 130 is not gradually inserted into the concave portion 123 of the tightening nut 120, but has the same effect as the above-described embodiment.
