About.

浴槽底部には、浴槽水を排水するための排水孔が形成されている。排水孔は、排水栓によって開閉される。その排水栓の開閉操作を、浴槽リムに設けた操作部によって遠隔操作するものがある（例えば、特許文献１、２）。排水栓はレリースワイヤの端部に取り付けられ、排水孔にはレリースワイヤの排水栓側の端部を支持する支持部材が取り付けられる。操作部はレリースワイヤと連結されており、操作部の操作によってレリースワイヤを進退させることができる。 A drain hole for draining bathtub water is formed in the bathtub bottom. The drain hole is opened and closed by a drain plug. Some open / close operation of the drain plug is remotely operated by an operation unit provided on the bathtub rim (for example, Patent Documents 1 and 2). The drain plug is attached to the end of the release wire, and a support member that supports the end of the release wire on the drain plug side is attached to the drain hole. The operation unit is connected to the release wire, and the release wire can be advanced and retracted by operating the operation unit.

特許文献１には、フランジ金具を介して、支持部材を排水孔に取り付けた構造が開示されている。また、特許文献２には、フランジ金具を介さずに、排水孔に対して支持部材を直接取り付けた構造が開示されている。 Patent Document 1 discloses a structure in which a support member is attached to a drain hole through a flange fitting. Patent Document 2 discloses a structure in which a support member is directly attached to a drain hole without using a flange fitting.

図８は、浴槽底部１１１の排水孔１１２に、フランジ金具１２０を介して、レリースワイヤ９２の支持部材１０を取り付けた構造を示す。 FIG. 8 shows a structure in which the support member 10 of the release wire 92 is attached to the drain hole 112 of the bathtub bottom 111 via the flange fitting 120.

支持部材１０は、係合爪１４と筒部１１とを有する。筒部１１は、レリースワイヤ９２の排水栓９６側の端部を支持する。ワイヤ９２の先端には、ロッド部９３が設けられている。そのロッド部９３には、排水栓９６が取り付けられる。排水孔１１２にはフランジ金具１２０が取り付けられ、そのフランジ金具１２０に対して支持部材１０の係合爪１４が係合している。 The support member 10 includes an engaging claw 14 and a cylinder portion 11. The cylinder portion 11 supports the end portion of the release wire 92 on the drain plug 96 side. A rod portion 93 is provided at the tip of the wire 92. A drain plug 96 is attached to the rod portion 93. A flange fitting 120 is attached to the drain hole 112, and the engagement claw 14 of the support member 10 is engaged with the flange fitting 120.

排水孔にフランジ金具を取り付けた構造においては、浴槽とフランジ金具との間に汚れが溜まりやすく、またその汚れを掃除しにくいという問題がある。また、フランジ金具が浴槽底面に露見してしまうことによるデザイン性の問題もある。 In the structure in which the flange fitting is attached to the drain hole, there is a problem that dirt easily collects between the bathtub and the flange fitting and it is difficult to clean the dirt. There is also a problem in design due to the flange metal fitting exposed on the bottom of the bathtub.

そこで、特許文献２に例示されるように、フランジ金具を介さずに、支持部材を排水孔に直接取り付ける構造が提案されている。フランジ金具を使わないことで、上記問題を解消でき、また部品点数削減によるコストダウンも図れる。 Therefore, as exemplified in Patent Document 2, there has been proposed a structure in which a support member is directly attached to a drain hole without using a flange fitting. By not using flange brackets, the above problems can be solved, and the cost can be reduced by reducing the number of parts.

現在、浴槽は金型を使って成形されることが多い。この成形時に排水孔も成形することは困難であることから、排水孔は後加工であけられる。そのため、加工誤差により、排水孔は高い寸法精度を得にくい。寸法にばらつきが生じやすい排水孔に対して直接支持部材の係合爪を係合させるとガタつくことがある。支持部材がガタついた状態で取り付けられると、排水栓を閉じた際の水密性に影響が出る。また、排水栓を使用者が足踏みした際に、排水孔に対する係合爪の係合が外れるおそれがある。そこで、係合爪をより硬質にするなどして、係合爪の反発力を大きくする対策が考えられる。排水孔の寸法が多少ばらついても、係合爪の大きな反発力でもって、排水孔に対して支持部材を強固に固定させ、ガタつきにくくできる。 Currently, bathtubs are often molded using molds. Since it is difficult to mold the drainage holes at the time of molding, the drainage holes are opened by post-processing. Therefore, it is difficult to obtain high dimensional accuracy in the drainage hole due to processing errors. When the engaging claw of the support member is directly engaged with the drainage hole in which the size is likely to vary, there is a case where the rattling is loose. If the support member is attached in a loose state, the water tightness when the drain plug is closed is affected. Further, when the user steps on the drain plug, the engagement claw may be disengaged from the drain hole. Therefore, a measure to increase the repulsive force of the engaging claw by making the engaging claw harder or the like can be considered. Even if the dimensions of the drainage holes vary somewhat, the support member can be firmly fixed to the drainage holes with a large repulsive force of the engaging claws, and it is possible to prevent rattling.

しかし、係合爪が硬質で反発力が大きいと、排水孔の上方から支持部材を押圧して、係合爪を弾性変形させる作業性が悪くなり、支持部材が斜めに傾いた状態になりやすい。すなわち、図９（ａ）に示すように、例えば円筒状の治具８０で支持部材１０を下方に押圧した際に、支持部材１０に対して治具８０が横滑りし、水平面内で局所的に偏った押圧力が支持部材１０に対して加わり、支持部材１０が斜めに傾きやすくなる。支持部材１０が斜めに傾いた状態で押圧されると、図９（ｂ）に示すように、係合爪１４が治具８０と浴槽底部との間で強く挟まれ折れることがある。また、係合爪１４が硬質であると、柔軟性（可撓性）が小さく、より折れやすくなる。 However, if the engaging claw is hard and the repulsive force is large, the workability of elastically deforming the engaging claw by pressing the supporting member from above the drainage hole is deteriorated, and the supporting member tends to be inclined obliquely. . That is, as shown in FIG. 9A, for example, when the support member 10 is pressed downward with a cylindrical jig 80, the jig 80 slides sideways with respect to the support member 10 and locally in the horizontal plane. The biased pressing force is applied to the support member 10, and the support member 10 is easily inclined obliquely. When the support member 10 is pressed in an inclined state, the engaging claws 14 may be strongly sandwiched between the jig 80 and the bathtub bottom as shown in FIG. 9B. Moreover, when the engaging claw 14 is hard, softness (flexibility) is small and it becomes easy to break.

なお、フランジ金具は成形品であり寸法精度が高い。また、一般に支持部材は樹脂成形品であり、寸法精度が高い。寸法精度の高いものどうしを係合させるにあたってはガタツキが生じにくい。したがって、フランジ金具に対して支持部材を係合させる場合には、ガタツキを吸収するために、係合爪の反発力を大きくする必要がなく、係合爪を比較的軟質にできる。係合爪の反発力が比較的に小さいと、支持部材を下方に押圧するのが容易になり、支持部材が斜めに傾きにくい。また、治具を使わなくても、指先で支持部材を下方に押圧して係合爪をフランジ金具に係合させることが可能である。さらに、支持部材が斜めに傾いた状態で押圧されても、係合爪が軟質で弾性しやすいため折れにくい。 The flange bracket is a molded product and has high dimensional accuracy. In general, the support member is a resin molded product and has high dimensional accuracy. When engaging high precision dimensional objects, rattling is unlikely to occur. Therefore, when the support member is engaged with the flange fitting, it is not necessary to increase the repulsive force of the engaging claw in order to absorb rattling, and the engaging claw can be made relatively soft. When the repulsive force of the engaging claw is relatively small, it becomes easy to press the support member downward, and the support member is difficult to tilt obliquely. Even without using a jig, it is possible to engage the engaging claw with the flange fitting by pressing the support member downward with the fingertip. Furthermore, even when the support member is pressed in an inclined state, the engaging claw is soft and easily elastic, and is not easily broken.

本発明は、フランジ金具を介さずに支持部材を排水孔に直接係合させるために、係合爪の反発力をより大きく、あるいはより硬質にしたことにより、支持部材が斜めに傾いた状態で押圧されやすくなり係合爪が折れるという、フランジ金具を用いない構造特有の課題に着眼してなされたものである。 In the present invention, in order to directly engage the support member with the drainage hole without using the flange metal fitting, the support member is inclined obliquely by making the repulsive force of the engaging claw larger or harder. This was made by focusing on the problem peculiar to the structure that does not use the flange metal fitting, which is easily pressed and the engaging claw is broken.

すなわち、本発明は、支持部材が斜めに傾きにくく大きな力をかけることが可能な治具及びそれを用いた支持部材の取付方法を提供する。 That is, this invention provides the jig | tool which can apply big force with a support member being hard to incline diagonally, and the attachment method of a support member using the same.

以下、図面を参照し、本発明の実施形態について説明する。各図面中、同じ要素には同じ符号を付している。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same elements are denoted by the same reference numerals.

以下の実施形態では、槽体として浴槽を例に挙げて説明するが、浴槽に限らず、洗面器等の槽体に対しても本発明は適用可能である。 In the following embodiments, a tub is described as an example of a tank body, but the present invention is not limited to a bathtub and may be applied to a tank body such as a basin.

図１に示すように、浴槽１００は、底部１０１と、側壁部１０２と、側壁部１０２の上端にフランジ状に設けられたリム１０３とを有する。また、図４（ａ）、（ｂ）に示すように、底部１０１には凹部１０５が設けられている。その凹部１０５の底には、排水孔１０６が貫通孔もしくは開口として形成されている。 As illustrated in FIG. 1, the bathtub 100 includes a bottom portion 101, a side wall portion 102, and a rim 103 provided in a flange shape on the upper end of the side wall portion 102. Further, as shown in FIGS. 4A and 4B, the bottom 101 is provided with a recess 105. A drain hole 106 is formed as a through hole or an opening at the bottom of the recess 105.

凹部１０５の底において、排水孔１０６の外周側には、リング状のフランジ部１０７が設けられている。フランジ部１０７の上面は水平面となっている。 A ring-shaped flange 107 is provided on the outer peripheral side of the drain hole 106 at the bottom of the recess 105. The upper surface of the flange portion 107 is a horizontal plane.

なお、本明細書において、「水平」とは、鉛直方向に対して直交する方向、もしくは浴槽設置面に対して平行な方向を意味する。また、水平及び鉛直方向に対して傾いた状態を「斜め」とする。 In the present specification, “horizontal” means a direction orthogonal to the vertical direction or a direction parallel to the bathtub installation surface. Further, the state inclined with respect to the horizontal and vertical directions is defined as “oblique”.

浴槽１００は、例えば炭素繊維、ガラス繊維などを混入させた樹脂材料を、金型で成形して得られる。底部１０１、側壁部１０２、リム１０３および凹部１０５は一体に成形される。ただし、排水孔１０６を金型を使った成形時に形成するのは困難であることから、排水孔１０６は成形後の後加工によってあけられる。 The bathtub 100 is obtained, for example, by molding a resin material mixed with carbon fiber, glass fiber, or the like with a mold. The bottom part 101, the side wall part 102, the rim 103, and the recessed part 105 are integrally molded. However, since it is difficult to form the drain holes 106 at the time of molding using a mold, the drain holes 106 are opened by post-processing after molding.

浴槽１００の外側には、遠隔操作用レリース９０が設けられている。遠隔操作用レリース９０はレリースワイヤを有する。図４（ａ）、（ｂ）に示すように、レリースワイヤ９２の一方の端部（排水栓側の端部）は、排水孔１０６の下方から排水孔１０６に通じている。レリースワイヤ９２の排水栓側の端部には、ロッド部９３が設けられている。 A remote operation release 90 is provided outside the bathtub 100. The remote operation release 90 has a release wire. As shown in FIGS. 4A and 4B, one end of the release wire 92 (the end on the drain plug side) communicates with the drain hole 106 from below the drain hole 106. A rod portion 93 is provided at the end of the release wire 92 on the drain plug side.

浴槽１００のリム１０３には、例えば押しボタン式の操作部９５が設けられている。レリースワイヤ９２の他方の端部は操作部９５に連結され、操作部９５の操作によってレリースワイヤ９２は進退可能である。 The rim 103 of the bathtub 100 is provided with, for example, a push button type operation unit 95. The other end of the release wire 92 is connected to the operation unit 95, and the release wire 92 can be advanced and retracted by operating the operation unit 95.

排水孔１０６には、レリースワイヤ９２の排水栓側の端部を支持するための支持部材１０が取り付けられる。図２（ａ）は支持部材１０の斜視図であり、図２（ｂ）はその上面図である。 A support member 10 for supporting the end of the release wire 92 on the drain plug side is attached to the drain hole 106. 2A is a perspective view of the support member 10, and FIG. 2B is a top view thereof.

支持部材１０は、リング部１２、筒部１１、アーム部１３、係合爪１４を有する。支持部材１０は、例えば樹脂材料からなり、リング部１２、筒部１１、アーム部１３および係合爪１４は一体に設けられている。 The support member 10 includes a ring part 12, a cylinder part 11, an arm part 13, and an engagement claw 14. The support member 10 is made of, for example, a resin material, and the ring portion 12, the cylinder portion 11, the arm portion 13, and the engagement claw 14 are integrally provided.

リング部１２の中央に筒部１１が位置する。筒部１１とリング部１２とは、アーム部１３によって結合されている。周方向で隣り合うアーム部１３とアーム部１３との間は、空所１９となっている。図では、アーム部１３は例えば４つであるが、その数は任意である。 The cylindrical portion 11 is located at the center of the ring portion 12. The cylinder part 11 and the ring part 12 are coupled by an arm part 13. A space 19 is formed between the arm portion 13 and the arm portion 13 adjacent in the circumferential direction. In the figure, there are four arm portions 13, for example, but the number is arbitrary.

係合爪１４は、筒部１１の軸方向に沿って、リング部１２から下方へ突出している。リング部１２の周方向における係合爪１４の位置とアーム部１３の位置とは一致する。例えば周方向に９０°間隔で離間して４つの係合爪１４が設けられている。係合爪１４の数も任意である。 The engaging claw 14 protrudes downward from the ring portion 12 along the axial direction of the tube portion 11. The position of the engaging claw 14 and the position of the arm part 13 in the circumferential direction of the ring part 12 coincide. For example, four engagement claws 14 are provided at intervals of 90 ° in the circumferential direction. The number of the engaging claws 14 is also arbitrary.

係合爪１４は、リング部１２側の根元部分を支点に、リング部１２の径方向の内側に倒れるように弾性変形可能となっている。図４（ａ）、（ｂ）に示されるように、係合爪１４には段部１６が設けられている。その段部１６と下端との間には傾斜面１５が設けられている。傾斜面１５は、下端側の部分ほど、リング部１２の径方向の内側に位置する。段部１６及び傾斜面１５は、リング部１２の径方向の外側に向いている。 The engaging claw 14 is elastically deformable so as to fall inward in the radial direction of the ring portion 12 with the base portion on the ring portion 12 side as a fulcrum. As shown in FIGS. 4A and 4B, the engaging claw 14 is provided with a stepped portion 16. An inclined surface 15 is provided between the step 16 and the lower end. The inclined surface 15 is located on the inner side in the radial direction of the ring portion 12 as the lower end side portion. The step portion 16 and the inclined surface 15 are directed outward in the radial direction of the ring portion 12.

以下に説明する治具を用いて支持部材１０を排水孔１０６の上方から押圧することで、支持部材１０を排水孔１０６に取り付けることができる。 The support member 10 can be attached to the drain hole 106 by pressing the support member 10 from above the drain hole 106 using a jig described below.

（第１実施形態）
図３は、第１実施形態に係る治具２０の斜視図である。 (First embodiment)
FIG. 3 is a perspective view of the jig 20 according to the first embodiment.

治具２０は、例えば樹脂材料からなり、円筒状に形成されている。治具２０の下端には押圧部２１が設けられている。押圧部２１はリング状の平坦面として形成されている。押圧部２１の中央には貫通孔２２が形成されている。貫通孔２２は、押圧部２１を貫通し、治具２０の内部に通じている。 The jig 20 is made of a resin material, for example, and is formed in a cylindrical shape. A pressing portion 21 is provided at the lower end of the jig 20. The pressing part 21 is formed as a ring-shaped flat surface. A through hole 22 is formed at the center of the pressing portion 21. The through hole 22 passes through the pressing portion 21 and communicates with the inside of the jig 20.

次に、図４（ａ）〜（ｂ）を参照して、第１実施形態に係る治具２０を用いた支持部材１０の取付方法について説明する。 Next, with reference to FIG. 4 (a)-(b), the attachment method of the supporting member 10 using the jig | tool 20 which concerns on 1st Embodiment is demonstrated.

まず、支持部材１０を、図４（ａ）に示すように、浴槽１００の底部１０１の凹部１０５内に位置させる。係合爪１４が弾性変形せず自然状態のとき、係合爪１４は排水孔１０６の外周に設けられたフランジ部１０７に引っ掛かる。そこで、支持部材１０を上方から押圧して、係合爪１４を弾性変形させて排水孔１０６に挿入させる必要がある。 First, the support member 10 is positioned in the concave portion 105 of the bottom 101 of the bathtub 100 as shown in FIG. When the engaging claw 14 is not elastically deformed and is in a natural state, the engaging claw 14 is caught by a flange portion 107 provided on the outer periphery of the drain hole 106. Therefore, it is necessary to press the support member 10 from above to elastically deform the engaging claw 14 and insert it into the drain hole 106.

本実施形態では、前述した治具２０を用いて支持部材１０を下方に押圧する。治具２０を使わない場合は、指先で支持部材１０を押圧することになるが、これは支持部材１０に大きな力を加えにくい。治具２０を使うことで、手のひらで治具２０を押圧して支持部材１０に大きな力を加えやすい。 In the present embodiment, the support member 10 is pressed downward using the jig 20 described above. When the jig 20 is not used, the support member 10 is pressed with the fingertip, but this is difficult to apply a large force to the support member 10. By using the jig 20, it is easy to apply a large force to the support member 10 by pressing the jig 20 with the palm.

治具２０の下端の押圧部２１を、支持部材１０のリング部１２の上面及びアーム部１３の上面に当接させながら、支持部材１０に対して下方への押圧力を与える。 While the pressing portion 21 at the lower end of the jig 20 is brought into contact with the upper surface of the ring portion 12 and the upper surface of the arm portion 13 of the supporting member 10, a downward pressing force is applied to the supporting member 10.

このとき、支持部材１０に対して押圧力が伝達される伝達部の位置がずれないように、支持部材１０に対して治具２０を連結させる。「押圧力が伝達される伝達部」は、治具２０の押圧部２１と支持部材１０との当接部である。 At this time, the jig 20 is connected to the support member 10 so that the position of the transmission portion to which the pressing force is transmitted to the support member 10 does not shift. The “transmitting portion to which the pressing force is transmitted” is a contact portion between the pressing portion 21 of the jig 20 and the support member 10.

具体的には、治具２０の貫通孔２２に、支持部材１０の筒部１１を嵌合させる。貫通孔２２の孔径は、筒部１１の外径よりもわずかに大きい。貫通孔２２に筒部１１が嵌合することで、支持部材１０に対する治具２０の横滑りが規制される。すなわち、筒部１１に貫通孔２２の内壁がぶつかることで、リング部１２の径方向への治具２０の位置ずれが規制される。 Specifically, the cylindrical portion 11 of the support member 10 is fitted into the through hole 22 of the jig 20. The hole diameter of the through hole 22 is slightly larger than the outer diameter of the cylindrical portion 11. The side slip of the jig 20 with respect to the support member 10 is restricted by fitting the cylindrical portion 11 into the through hole 22. That is, the displacement of the jig 20 in the radial direction of the ring portion 12 is restricted by the inner wall of the through hole 22 colliding with the cylindrical portion 11.

その状態で、治具２０を下方に押圧すると、支持部材１０も下方へと押圧される。支持部材１０が下方に押圧されると、係合爪１４の傾斜面１５がフランジ部１０７の内側上端の角部に当接しつつ、係合爪１４が径方向内側へと倒れるようにして弾性変形し、排水孔１０６に挿入される。 In this state, when the jig 20 is pressed downward, the support member 10 is also pressed downward. When the support member 10 is pressed downward, the inclined surface 15 of the engaging claw 14 is in contact with the corner portion of the inner upper end of the flange portion 107 and elastically deforms so that the engaging claw 14 falls down radially inward. And inserted into the drain hole 106.

傾斜面１５が排水孔１０６の下方へと突出すると、復元力により係合爪１４は径方向外側に戻され、図４（ｂ）に示すように、係合爪１４の段部１６がフランジ部１０７の内側下端の角部に係合する。そして、支持部材１０のリング部１２の下面と、係合爪１４の段部１６との間にフランジ部１０７が狭圧され、支持部材１０が排水孔１０６に対して固定される。 When the inclined surface 15 protrudes downward from the drain hole 106, the engaging claw 14 is returned to the outside in the radial direction by the restoring force, and the step 16 of the engaging claw 14 is a flange portion as shown in FIG. Engage with the corner of the inner bottom edge of 107. The flange portion 107 is narrowed between the lower surface of the ring portion 12 of the support member 10 and the step portion 16 of the engagement claw 14, and the support member 10 is fixed to the drain hole 106.

前述したように、寸法にばらつきが生じやすい排水孔１０６に対して直接係合爪１４を係合させるとガタつくことがある。そこで、本実施形態では、ガタツキを吸収可能に係合爪１４を比較的硬質もしくは係合爪１４の反発力を大きくている。なおかつ、係合爪１４を硬質もしくは反発力を大きくした場合に生じ得る前述した問題に対する解決を、上記治具２０を用いることで図っている。 As described above, when the engaging claw 14 is directly engaged with the drain hole 106 in which variations in dimensions are likely to occur, rattling may occur. Therefore, in the present embodiment, the engaging claw 14 is relatively hard or the repulsive force of the engaging claw 14 is increased so as to absorb backlash. In addition, the jig 20 is used to solve the above-described problems that may occur when the engaging claw 14 is hard or has a large repulsive force.

すなわち、治具２０と支持部材１０とを横方向の位置ずれを規制するようにそれら両者を連結して支持部材１０を押圧している。そのため、治具２０から支持部材１０への押圧力の伝達部の位置が変動しない。これにより、支持部材１０側の伝達部に対して均等に押圧力を加えやすくなり、支持部材１０は斜めに傾きにくくなる。 That is, the jig 20 and the support member 10 are connected to each other so as to restrict the positional deviation in the lateral direction and press the support member 10. Therefore, the position of the transmission portion of the pressing force from the jig 20 to the support member 10 does not change. Thereby, it becomes easy to apply a pressing force equally to the transmission part on the support member 10 side, and the support member 10 becomes difficult to tilt obliquely.

支持部材１０を傾きにくくして押圧できることで、係合爪１４が折れる頻度を低減できる。この結果、排水孔１０６に対する支持部材１０の取り付け作業効率を向上できる。また、係合爪１４の破損による支持部材１０の損失を低減でき、コストアップをまねかない。 Since the support member 10 can be pressed with difficulty in tilting, the frequency with which the engaging claws 14 are broken can be reduced. As a result, the efficiency of attaching the support member 10 to the drain hole 106 can be improved. Moreover, the loss of the support member 10 due to the breakage of the engaging claws 14 can be reduced, and the cost is not increased.

遠隔操作用レリースワイヤ９２は、排水孔１０６の下方から支持部材１０の筒部１１に挿入される。レリースワイヤ９２の先端のロッド部９３は、筒部１１から上方（浴槽内）に突出する。 The remote operation release wire 92 is inserted into the cylindrical portion 11 of the support member 10 from below the drain hole 106. The rod portion 93 at the tip of the release wire 92 protrudes upward (in the bathtub) from the tube portion 11.

支持部材１０を排水孔１０６に取り付けた後、治具２０を支持部材１０上から取り外し、ロッド部９３に、図８に例示される排水栓９６を取り付ける。 After the support member 10 is attached to the drain hole 106, the jig 20 is removed from the support member 10, and the drain plug 96 illustrated in FIG. 8 is attached to the rod portion 93.

なお、治具２０を支持部材１０に対して連結させた状態で、筒部１１及びロッド部９３は、治具２０の貫通孔２２を通じて、円筒状の治具２０の内部に挿入される。したがって、筒部１１及びロッド部９３は、治具２０の押圧部２１によって押圧されず、破損を防止できる。 In addition, the cylindrical part 11 and the rod part 93 are inserted into the cylindrical jig 20 through the through hole 22 of the jig 20 in a state where the jig 20 is connected to the support member 10. Therefore, the cylinder part 11 and the rod part 93 are not pressed by the pressing part 21 of the jig 20 and can be prevented from being damaged.

筒部１１は、レリースワイヤ９２の排水栓側の端部を上下動自在に支持する。図１に示す浴槽１００のリム１０３に設けられた操作部９５を操作することで、レリースワイヤ９２を進退させ、排水栓９６を開位置と閉位置とに移動させることができる。開位置で、排水栓９６は凹部１０５よりも上方に持ち上げられ、排水孔１０６を浴槽内と連通させる。浴槽内の浴槽水は、支持部材１０のアーム部１３間の空所１９を通じて排水孔１０６に流れ込み、さらに図示しない排水管を通って浴槽外に排水される。閉位置で、排水栓９６は凹部１０５を水密に閉塞する。これにより、浴槽に浴槽水を溜めることができる。 The cylinder part 11 supports the end part on the drain plug side of the release wire 92 so as to be movable up and down. By operating the operation part 95 provided in the rim | limb 103 of the bathtub 100 shown in FIG. 1, the release wire 92 can be advanced or retracted, and the drain plug 96 can be moved to an open position and a closed position. In the open position, the drain plug 96 is lifted above the recess 105, and allows the drain hole 106 to communicate with the interior of the bathtub. The bathtub water in the bathtub flows into the drain hole 106 through the space 19 between the arm portions 13 of the support member 10, and further drains outside the bathtub through a drain pipe (not shown). In the closed position, the drain plug 96 closes the recess 105 in a watertight manner. Thereby, bathtub water can be stored in the bathtub.

排水栓９６の開位置と閉位置とは、図示しないばね等を用いたスラストロック機構によって保持される。スラストロック機構は、支持部材１０の筒部１１に内蔵されている、あるいは操作部９５側に設けてもよい。 The open position and the closed position of the drain plug 96 are held by a thrust lock mechanism using a spring or the like (not shown). The thrust lock mechanism may be built in the cylindrical portion 11 of the support member 10 or provided on the operation portion 95 side.

（第２実施形態）
次に、図５は、第２実施形態に係る治具３０の斜視図である。 (Second Embodiment)
Next, FIG. 5 is a perspective view of the jig 30 according to the second embodiment.

治具３０は、例えば樹脂材料からなる。治具３０は円筒部３５を有し、その円筒部３５の下端には押圧部２１が設けられている。押圧部２１はリング状の平坦面として形成されている。押圧部２１の中央には貫通孔２２が形成されている。貫通孔２２は、押圧部２１を貫通し、円筒部３５の内部に通じている。 The jig 30 is made of, for example, a resin material. The jig 30 has a cylindrical portion 35, and a pressing portion 21 is provided at the lower end of the cylindrical portion 35. The pressing part 21 is formed as a ring-shaped flat surface. A through hole 22 is formed at the center of the pressing portion 21. The through hole 22 passes through the pressing portion 21 and communicates with the inside of the cylindrical portion 35.

治具３０には、押圧部２１から下方に突出する複数の突起３１が設けられている。図では、例えば４つの突起３１が、押圧部２１の周方向に９０°間隔で設けられている。なお、突起３１の数は４つに限ることはなく、任意である。 The jig 30 is provided with a plurality of protrusions 31 protruding downward from the pressing portion 21. In the figure, for example, four protrusions 31 are provided at 90 ° intervals in the circumferential direction of the pressing portion 21. The number of protrusions 31 is not limited to four and is arbitrary.

複数の突起３１の内側には、それら複数の突起３１に囲まれた嵌合孔３２が設けられている。嵌合孔３２は、貫通孔２２に通じている。 A fitting hole 32 surrounded by the plurality of protrusions 31 is provided inside the plurality of protrusions 31. The fitting hole 32 communicates with the through hole 22.

各突起３１の内周面側には、回転規制部３１ｄが設けられている。回転規制部３１ｄは、周方向で隣り合う他の突起３１側に向かって出っ張っている。周方向で隣り合う突起３１間において、回転規制部３１ｄ間の間隔は、突起３１の側面３１ｃ間の間隔よりも狭い。側面３１ｃは、隣の突起３１側に向けられている側面である。 A rotation restricting portion 31 d is provided on the inner peripheral surface side of each protrusion 31. 31 d of rotation control parts protrude toward the other protrusion 31 side adjacent in the circumferential direction. Between the protrusions 31 adjacent in the circumferential direction, the interval between the rotation restricting portions 31 d is narrower than the interval between the side surfaces 31 c of the protrusion 31. The side surface 31c is a side surface directed toward the adjacent protrusion 31 side.

突起３１の下端面３１ｂは、平坦である。突起３１において、押圧部２１の径方向外側に向いている側面３１ａは曲面状になっている。この側面３１ａの曲率は、支持部材１０のリング部１２の内周面、あるいは排水孔１０６の内周面の曲率に合わせて設計されている。 The lower end surface 31b of the protrusion 31 is flat. In the protrusion 31, the side surface 31 a facing the radially outer side of the pressing portion 21 is curved. The curvature of the side surface 31 a is designed according to the curvature of the inner peripheral surface of the ring portion 12 of the support member 10 or the inner peripheral surface of the drain hole 106.

次に、本実施形態に係る治具３０を用いた支持部材１０の取付方法について説明する。 Next, a method for attaching the support member 10 using the jig 30 according to the present embodiment will be described.

治具３０の突起３１を、図２（ｂ）に示す支持部材１０のアーム部１３間に形成された空所１９に挿入する。支持部材１０の筒部１１は、複数の突起３１で囲まれた嵌合孔３２に収まる。筒部１１の上端部は、貫通孔２２を通じて円筒部３５内に突出する。そして、円筒部３５の下端の押圧部２１を、支持部材１０のリング部１２の上面及びアーム部１３の上面に当接させながら、支持部材１０に対して下方への押圧力を与える。 The protrusion 31 of the jig 30 is inserted into a space 19 formed between the arm portions 13 of the support member 10 shown in FIG. The cylindrical portion 11 of the support member 10 is accommodated in the fitting hole 32 surrounded by the plurality of protrusions 31. The upper end portion of the cylindrical portion 11 protrudes into the cylindrical portion 35 through the through hole 22. Then, a downward pressing force is applied to the support member 10 while bringing the pressing portion 21 at the lower end of the cylindrical portion 35 into contact with the upper surface of the ring portion 12 and the upper surface of the arm portion 13 of the support member 10.

このとき、本実施形態においても、貫通孔２２に筒部１１が嵌合することで、支持部材１０に対する治具３０の横滑りが規制される。すなわち、筒部１１に貫通孔２２の内壁がぶつかることで、リング部１２の径方向への治具３０の位置ずれが規制される。 At this time, also in this embodiment, the side slip of the jig 30 with respect to the support member 10 is restricted by fitting the cylindrical portion 11 into the through hole 22. That is, the displacement of the jig 30 in the radial direction of the ring portion 12 is restricted by the inner wall of the through hole 22 colliding with the cylindrical portion 11.

治具３０を介して支持部材１０が下方に押圧されると、図４（ａ）〜（ｂ）を参照して前述した実施形態と同様、係合爪１４が径方向内側へと倒れるようにして弾性変形し、排水孔１０６に挿入され、係合爪１４の段部１６がフランジ部１０７の内側下端のコーナーに係合する。そして、支持部材１０のリング部１２の下面と、係合爪１４の段部１６との間にフランジ部１０７が狭圧され、支持部材１０が排水孔１０６に対して固定される。 When the support member 10 is pressed downward via the jig 30, the engagement claw 14 is caused to fall radially inward as in the embodiment described above with reference to FIGS. 4 (a) to 4 (b). It is elastically deformed and inserted into the drain hole 106, and the step 16 of the engaging claw 14 engages with the corner at the inner bottom end of the flange 107. The flange portion 107 is narrowed between the lower surface of the ring portion 12 of the support member 10 and the step portion 16 of the engagement claw 14, and the support member 10 is fixed to the drain hole 106.

前述したように、ガタツキを吸収可能に係合爪１４を比較的硬質に、もしくは係合爪１４の反発力を大きくている。そして、本実施形態においても、係合爪１４を硬質もしくは反発力を大きくした場合に生じ得る問題に対する解決を、上記治具３０を用いることで図っている。 As described above, the engaging claw 14 is made relatively hard so that the backlash can be absorbed, or the repulsive force of the engaging claw 14 is increased. Also in this embodiment, the jig 30 is used to solve a problem that may occur when the engaging claw 14 is hard or has a large repulsive force.

すなわち、治具３０と支持部材１０とを横方向の位置ずれを規制するようにそれら両者を連結して支持部材１０を押圧している。これにより、支持部材１０側の伝達部に対して均等に押圧力を加えやすくなり、支持部材１０は斜めに傾きにくくなる。支持部材１０を傾きにくくして押圧できることで、係合爪１４が折れる頻度を低減できる。この結果、排水孔１０６に対する支持部材１０の取り付け作業効率を向上できる。また、係合爪１４の破損による支持部材１０の損失を低減でき、コストアップをまねかない。 That is, the jig 30 and the support member 10 are connected to each other so as to restrict the positional deviation in the lateral direction, and the support member 10 is pressed. Thereby, it becomes easy to apply a pressing force equally to the transmission part on the support member 10 side, and the support member 10 becomes difficult to tilt obliquely. Since the support member 10 can be pressed with difficulty in tilting, the frequency with which the engaging claws 14 are broken can be reduced. As a result, the efficiency of attaching the support member 10 to the drain hole 106 can be improved. Moreover, the loss of the support member 10 due to the breakage of the engaging claws 14 can be reduced, and the cost is not increased.

また、本実施形態に係る治具３０には、支持部材１０が仮に斜めに傾いた状態で押圧されても、係合爪１４に大きな力が加わることを防止する保護部が設けられている。突起３１の下端面３１ｂが、その保護部として機能する。 In addition, the jig 30 according to the present embodiment is provided with a protective portion that prevents a large force from being applied to the engaging claws 14 even if the support member 10 is pressed while being inclined obliquely. The lower end surface 31b of the protrusion 31 functions as the protection part.

図６に示すように、支持部材１０が斜めに傾くと、支持部材１０が下方に倒れたサイドの反対側の係合爪１４は排水孔１０６周辺のフランジ部１０７の上面に乗り上げる。このとき、突起３１の下端面３１ｂがフランジ部１０７の上面あるいは角部に当接する。この当接により、係合爪１４に対して破損するほどの大きな力が加わる前に、支持部材１０のそれ以上の挿入が制限される。この結果、係合爪１４が折れることを確実に防止できる。 As shown in FIG. 6, when the support member 10 is inclined, the engaging claw 14 on the side opposite to the side on which the support member 10 has fallen down rides on the upper surface of the flange portion 107 around the drain hole 106. At this time, the lower end surface 31 b of the protrusion 31 comes into contact with the upper surface or the corner of the flange portion 107. This contact restricts further insertion of the support member 10 before a large force is applied to the engaging claws 14 to cause damage. As a result, the engagement claw 14 can be reliably prevented from breaking.

突起３１が支持部材１０の空所１９に挿入され、治具３０の押圧部２１が支持部材１０のリング部１２の上面及びアーム部１３の上面に当接した状態で、突起３１の下端面３１ｂが、係合爪１４よりも下方に突出することが望ましい。これにより、係合爪１４に対して破損するほどの大きな力が加わる前に、確実に突起３１の下端面３１ｂをフランジ部１０７に当接させて、係合爪１４を保護することができる。 The lower end surface 31b of the protrusion 31 is inserted in the state where the protrusion 31 is inserted into the space 19 of the support member 10 and the pressing portion 21 of the jig 30 is in contact with the upper surface of the ring portion 12 and the upper surface of the arm portion 13. However, it is desirable to protrude below the engaging claw 14. Thus, the engaging claw 14 can be protected by reliably bringing the lower end surface 31b of the protrusion 31 into contact with the flange portion 107 before a large force is applied to the engaging claw 14 so as to be damaged.

あるいは、突起３１が支持部材１０の空所１９に挿入され、押圧部２１が支持部材１０のリング部１２の上面及びアーム部１３の上面に当接した状態で、突起３１の突出長さと、係合爪１４の突出長さとがほぼ同じであってもかまわない。この場合でも、突起３１が係合爪１４よりもリング部１２の径方向の内側に位置することから、支持部材１０が傾いたときに、突起３１の下端面３１ｂが係合爪１４よりもフランジ部１０７に当接しやすくなる。 Alternatively, the protrusion 31 is inserted into the space 19 of the support member 10 and the pressing portion 21 is in contact with the upper surface of the ring portion 12 and the upper surface of the arm portion 13 of the support member 10. It does not matter if the protruding length of the claw 14 is substantially the same. Even in this case, since the protrusion 31 is located on the inner side in the radial direction of the ring portion 12 with respect to the engagement claw 14, the lower end surface 31 b of the protrusion 31 is more flanged than the engagement claw 14 when the support member 10 is inclined. It becomes easy to contact the portion 107.

あるいは、突起３１の突出長さが係合爪１４の突出長さよりも若干短くてもよい。ただし、係合爪１４の突出長さが、突起３１の突出長さよりもあまりに長いと、突起３１の下端面３１ｂがフランジ部１０７に当接する前に、係合爪１４が治具３０の押圧部２１とフランジ部１０７との間で大きな力で狭圧されてしまう。 Alternatively, the protruding length of the protrusion 31 may be slightly shorter than the protruding length of the engaging claw 14. However, if the protruding length of the engaging claw 14 is too long than the protruding length of the protrusion 31, the engaging claw 14 is pressed by the pressing portion of the jig 30 before the lower end surface 31 b of the protrusion 31 contacts the flange portion 107. 21 and the flange portion 107 are narrowed by a large force.

すなわち、突起３１の下端面３１ｂがフランジ部１０７から浮いた状態で、係合爪１４が、押圧部２１とフランジ部１０７との間で大きな力で狭圧されないようにすればよい。 That is, it is only necessary to prevent the engaging claw 14 from being narrowed with a large force between the pressing portion 21 and the flange portion 107 in a state where the lower end surface 31 b of the protrusion 31 is lifted from the flange portion 107.

また、突起３１には、図５に示すように回転規制部３１ｄが設けられている。突起３１が支持部材１０の空所１９に挿入された状態で、アーム部１３は、周方向で隣り合う回転規制部３１ｄの間に位置する。回転規制部３１ｄとアーム部１３とが当接することで、支持部材１０に対する治具３０の回転方向の横滑りが規制される。この回転方向の横滑りが規制されることで、支持部材１０をより傾きにくくできる。さらに、治具３０で支持部材１０を押圧するときの力の伝達ロスを抑制できる。 Further, the protrusion 31 is provided with a rotation restricting portion 31d as shown in FIG. In a state where the protrusion 31 is inserted into the space 19 of the support member 10, the arm portion 13 is located between the rotation restricting portions 31 d adjacent in the circumferential direction. When the rotation restricting portion 31d and the arm portion 13 come into contact with each other, the side slip in the rotation direction of the jig 30 with respect to the support member 10 is restricted. By restricting the skid in the rotational direction, the support member 10 can be made less inclined. Furthermore, the transmission loss of force when pressing the support member 10 with the jig 30 can be suppressed.

また、周方向で隣り合う回転規制部３１ｄ間の間隔は、周方向で隣り合う突起３１の側面３１ｃ間の間隔よりも狭い。回転規制部３１ｄ間の間隔を狭くすることで、回転方向の滑り移動量を小さくできる。突起３１の側面３１ｃ間の間隔を広げることで、押圧時における突起３１と係合爪１４との干渉を確実に防ぐことができる。 Moreover, the space | interval between the rotation control parts 31d adjacent in the circumferential direction is narrower than the space | interval between the side surfaces 31c of the processus | protrusion 31 adjacent in the circumferential direction. By reducing the interval between the rotation restricting portions 31d, the amount of sliding movement in the rotation direction can be reduced. By widening the interval between the side surfaces 31c of the protrusion 31, it is possible to reliably prevent interference between the protrusion 31 and the engaging claw 14 during pressing.

また、突起３１の側面３１ａを排水孔１０６の内周面に当接させつつ、突起３１を排水孔１０６に挿入することで、治具３０の軸方向を排水孔１０６の径方向に対して垂直にしやすくなる。すなわち、排水孔１０６に対して治具３０を垂直に起立させやすくなる。治具３０が排水孔１０６に対して垂直になることで、治具３０に連結された支持部材１０の姿勢を水平に矯正できる。以下に説明する第３実施形態に係る治具４０は、その効果をより高めた構造を有する。 Further, by inserting the protrusion 31 into the drain hole 106 while bringing the side surface 31 a of the protrusion 31 into contact with the inner peripheral surface of the drain hole 106, the axial direction of the jig 30 is perpendicular to the radial direction of the drain hole 106. It becomes easy to. In other words, the jig 30 can easily stand upright with respect to the drain hole 106. Since the jig 30 is perpendicular to the drain hole 106, the posture of the support member 10 connected to the jig 30 can be corrected horizontally. The jig 40 according to the third embodiment described below has a structure in which the effect is further enhanced.

（第３実施形態）
図７（ａ）〜（ｃ）を参照して、第３実施形態に係る治具４０を用いた支持部材１０の取付方法を示す。 (Third embodiment)
With reference to Fig.7 (a)-(c), the attachment method of the supporting member 10 using the jig | tool 40 which concerns on 3rd Embodiment is shown.

第３実施形態に係る治具４０は、図５に示す第２実施形態に係る治具３０と同じ構造を有し、同じ作用及び効果が得られる。 The jig 40 according to the third embodiment has the same structure as the jig 30 according to the second embodiment shown in FIG. 5, and the same actions and effects can be obtained.

ただし、本実施形態に係る治具４０は、突起３１の突出長さが治具３０よりも長い。突起３１が支持部材１０の空所１９に挿入され、治具４０の押圧部２１が支持部材１０のリング部１２の上面及びアーム部１３の上面に当接した状態で、図７（ｂ）、（ｃ）に示すように、突起３１が係合爪１４よりも下方に突出する。 However, in the jig 40 according to this embodiment, the protrusion length of the protrusion 31 is longer than that of the jig 30. In the state where the protrusion 31 is inserted into the space 19 of the support member 10 and the pressing portion 21 of the jig 40 is in contact with the upper surface of the ring portion 12 and the upper surface of the arm portion 13 of FIG. As shown in (c), the protrusion 31 protrudes below the engaging claw 14.

突起３１の側面３１ａは、支持部材１０が水平状態になるように支持部材１０の姿勢を案内するガイド部として機能する。 The side surface 31a of the protrusion 31 functions as a guide portion that guides the posture of the support member 10 so that the support member 10 is in a horizontal state.

図７（ｂ）に示すように、治具３０の軸方向を排水孔１０６の径方向に対して垂直にした状態で、すべての突起３１を排水孔１０６に挿入すると、突起３１の側面３１ａと排水孔１０６の内周面との間には僅かに隙間が形成される。あるいは、突起３１の側面３１ａは、排水孔１０６の内周面に当接する。したがって、すべての突起３１を排水孔１０６に挿入すると、治具３０の傾きが規制され、排水孔１０６に対して治具３０は自然と垂直に起立する。 As shown in FIG. 7B, when all the projections 31 are inserted into the drainage holes 106 in a state where the axial direction of the jig 30 is perpendicular to the radial direction of the drainage holes 106, the side surfaces 31a of the projections 31 and A slight gap is formed between the inner peripheral surface of the drain hole 106. Alternatively, the side surface 31 a of the protrusion 31 contacts the inner peripheral surface of the drain hole 106. Therefore, when all the protrusions 31 are inserted into the drainage holes 106, the inclination of the jig 30 is restricted, and the jigs 30 stand up vertically with respect to the drainage holes 106.

治具４０の押圧部２１が支持部材１０の上面に当接した状態で、突起３１の下方への突出長さが係合爪１４の突出長さよりも長くなるようにすることで、確実かつ安定して治具４０を排水孔１０６に対して垂直に起立させることができる。 In a state where the pressing portion 21 of the jig 40 is in contact with the upper surface of the support member 10, the protruding length of the protrusion 31 is made longer than the protruding length of the engaging claw 14, thereby ensuring reliable and stable. Thus, the jig 40 can stand upright with respect to the drain hole 106.

治具４０が排水孔１０６に対して垂直に起立することで、治具４０に連結された支持部材１０の姿勢は自然と水平になる。その状態で治具４０によって支持部材１０を押圧することで、支持部材１０は水平状態を維持したまま排水孔１０６に挿入される。そして、係合爪１４がフランジ部１０７の下端の角部に係合する。 As the jig 40 stands upright with respect to the drain hole 106, the posture of the support member 10 connected to the jig 40 is naturally horizontal. By pressing the support member 10 with the jig 40 in this state, the support member 10 is inserted into the drain hole 106 while maintaining the horizontal state. Then, the engaging claw 14 engages with the corner portion at the lower end of the flange portion 107.

この結果、係合爪１４が折れることを確実に防止できる。また、支持部材１０が斜めに傾いた状態で押圧されることがないため、容易に支持部材１０を排水孔１０６に取り付けることが可能となる。 As a result, the engagement claw 14 can be reliably prevented from breaking. In addition, since the support member 10 is not pressed while being inclined, the support member 10 can be easily attached to the drain hole 106.
