Description

本発明は、シンク、洗面ボウル等の槽体の底面部に排水装置を接続する接続構造及び接続方法に関する。   The present invention relates to a connection structure and a connection method for connecting a drainage device to a bottom surface of a tank body such as a sink and a wash bowl.

家は多くの人にとって最も長い時間を過ごす場所である。過ごしやすさは、住宅設備のデザインだけでなく機能にもよる。キッチンで用いられるシンク等の槽体についても、利用者はスタイリッシュなデザインとともに機能性を求める傾向が強い。   The home is the place where most people spend the longest time. Ease of spending depends on the function as well as the design of the house. For tanks such as sinks used in the kitchen, users tend to demand functionality with a stylish design.

槽体の底面部には排水孔が形成される。排水孔の下側には、人の目に触れない箇所で排水装置が接続される。この接続構造では、通常、排水孔の周縁部に口金を取り付け、槽体の下側でこの口金に排水装置が接続される(特許文献1参照)。口金は、その上部にフランジとしての係止部が設けられ、その係止部が排水孔の周縁部に係止される。また、口金は、その下部の外周面に雄ねじ部が設けられる。口金の雄ねじ部には排水装置の一部としてのロックナットがねじ込まれ、ロックナットに排水装置の本体が取り付けられる。   A drainage hole is formed in the bottom surface of the tank body. A drainage device is connected to the lower side of the drainage hole at a location that is not touched by human eyes. In this connection structure, usually, a base is attached to the peripheral edge of the drainage hole, and a drainage device is connected to the base on the lower side of the tank body (see Patent Document 1). The cap is provided with a locking portion as a flange at the top, and the locking portion is locked to the peripheral edge of the drain hole. The base is provided with a male screw portion on the outer peripheral surface of the lower part thereof. A lock nut as a part of the drainage device is screwed into the male screw portion of the base, and the main body of the drainage device is attached to the lock nut.

この構造では、通常、排水孔の周縁部と口金との間をシールするため、ロックナットと排水孔の周縁部との間や、排水孔の周縁部と口金との間にパッキン等のシール部材が配置される。口金の雄ねじ部にロックナットを十分量締め付けると、ロックナットや口金によりシール部材が上下方向両側から挟み付けられ、その挟み付けによりシール性が発揮される。   In this structure, in order to seal between the peripheral edge of the drainage hole and the base, normally, a seal member such as packing is provided between the lock nut and the peripheral edge of the drainage hole, or between the peripheral edge of the drainage hole and the base. Is placed. When a sufficient amount of the lock nut is tightened on the male screw portion of the base, the seal member is sandwiched from both sides in the vertical direction by the lock nut and the base, and sealing performance is exhibited by the sandwich.

特開2012−1907号JP2012-1907

特許文献1の構造では、シール部材によるシール性を発揮させるため、口金の雄ねじ部にロックナットを十分量締め付ける必要があった。しかし、ロックナットの締め付け量を施工者によらず一定にするのは困難である。特に、ロックナットの締め付け量は、外部からの視認がしにくく、その施工品質にばらつきが生じかねなかった。ロックナットの締め付け量が不十分であると、シール部材により所望のシール性が得られず、排水装置から槽体内への水漏れの原因になりかねない。   In the structure of Patent Document 1, it is necessary to tighten a sufficient amount of a lock nut on the male screw portion of the base in order to exhibit the sealing performance by the sealing member. However, it is difficult to make the amount of tightening of the lock nut constant regardless of the installer. In particular, the tightening amount of the lock nut is difficult to visually recognize from the outside, and the construction quality may vary. If the amount of tightening of the lock nut is insufficient, the seal member cannot obtain a desired sealing property, which may cause water leakage from the drainage device into the tank body.

本発明は、このような課題に鑑みてなされたものであり、その目的は、槽体に排水装置を接続するにあたり、施工品質のばらつき又は水漏れの発生を抑制できる排水装置の接続構造及び接続方法を提供することにある。   The present invention has been made in view of such problems, and its purpose is to connect a drainage device connection structure and a connection that can suppress variations in construction quality or occurrence of water leakage in connecting the drainage device to the tank body. It is to provide a method.

上述の課題を解決するために、本発明のある態様は、排水装置の接続構造に関する。排水装置の接続構造は、槽体の底面部に排水装置を接続する構造であって、底面部に形成された排水孔と、排水孔の周縁部の下側に周縁部と上下に重なるように配置され、排水装置の一部を構成する連結体と、周縁部と連結体とを挟み込んで固定する接続具と、を備える。   In order to solve the above-described problems, an aspect of the present invention relates to a connection structure for a drainage device. The connection structure of the drainage device is a structure in which the drainage device is connected to the bottom surface portion of the tank body, so that the drainage hole formed in the bottom surface portion overlaps with the peripheral edge portion below and above the peripheral edge portion of the drainage hole. And a connecting body that is disposed and constitutes a part of the drainage device, and a connector that sandwiches and fixes the peripheral edge portion and the connecting body.

この態様によれば、排水孔の周縁部と上下に重なるように連結体を配置するため、排水孔に連結体を容易に上下方向に位置決めできる。また、その位置決めした連結体と排水孔の周縁部とを接続具により挟み込んで固定するため、排水孔に対する連結体や接続具の上下位置が施工者によりばらつき難くなり、施工品質のばらつきが抑えられる。   According to this aspect, since the coupling body is disposed so as to overlap the peripheral edge of the drainage hole, the coupling body can be easily positioned in the vertical direction in the drainage hole. In addition, since the positioned connecting body and the peripheral portion of the drainage hole are sandwiched and fixed by the connecting tool, the vertical position of the connecting body and the connecting tool with respect to the drainage hole is less likely to be varied by the installer, and variation in construction quality can be suppressed. .

また、前述の態様において、接続具と連結体又は周縁部の何れか一方とにより径方向両側から押し潰されたシール部材を更に備えてもよい。この態様によれば、シール部材の径方向両側の部材の間隔が施工誤差により変動し難く、施工品質のばらつきを抑えて所望のシール性を得られ、水漏れの発生を抑制できる。   Moreover, the above-mentioned aspect WHEREIN: You may further provide the sealing member crushed from the radial direction both sides by the connection tool and any one of the coupling body or the peripheral part. According to this aspect, the gap between the members on both radial sides of the seal member is unlikely to fluctuate due to construction errors, and it is possible to obtain a desired sealing property by suppressing variations in construction quality, thereby suppressing the occurrence of water leakage.

また、前述の態様において、接続具は、排水孔の周縁部に係止された第1接続部材と、第1接続部材に脱着可能に装着された第2接続部材と、を有し、第1接続部材と第2接続部材とにより周縁部と連結体とを挟み込んで固定し、第1接続部材が周縁部に係止されない非係止位置にあるとき、前記第2部前記第1接続部材に装着不能となり、第1接続部材が周縁部に係止される係止位置にあるとき、第2接続部材が第1接続部材に装着可能となるように寸法関係が定められていてもよい。この態様によれば、第1接続部材が所定位置にあるときにはじめて第2接続部材を装着でき、その装着後の第1接続部材及び第2接続部材の位置関係が施工者によりばらつき難くなり、施工品質のばらつきを良好に抑えられる。   Moreover, in the above-mentioned aspect, the connection tool includes a first connection member that is locked to the peripheral edge of the drain hole, and a second connection member that is detachably attached to the first connection member. When the connecting member and the second connecting member sandwich and fix the peripheral portion and the coupling body, and the first connecting member is in the non-locking position where it is not locked to the peripheral portion, the second portion is connected to the first connecting member. The dimensional relationship may be determined so that the second connection member can be attached to the first connection member when the attachment is impossible and the first connection member is in the locking position where the first connection member is locked to the peripheral edge. According to this aspect, the second connection member can be mounted only when the first connection member is in a predetermined position, and the positional relationship between the first connection member and the second connection member after the mounting is less likely to vary depending on the installer. Variations in construction quality can be satisfactorily suppressed.

また、前述の態様において、接続具は、排水孔の周縁部に係止された第1接続部材と、第1接続部材に脱着可能に装着された第2接続部材と、を有し、第1接続部材と第2接続部材とにより周縁部と連結体とを挟み込んで固定し、連結体が周縁部と上下に重ならない位置にあるとき、第2接続部材が第1接続部材に装着不能となり、連結体が周縁部と上下に重なる位置にあるとき、第2接続部材が第1接続部材に装着可能となるように寸法関係が定められていてもよい。この態様によれば、連結体が所定位置にあるときにはじめて第2接続部材を装着でき、その装着後の連結体及び第2接続部材の位置関係が施工者によりばらつき難くなり、施工品質のばらつきを良好に抑えられる。   Moreover, in the above-mentioned aspect, the connection tool includes a first connection member that is locked to the peripheral edge of the drain hole, and a second connection member that is detachably attached to the first connection member. When the connecting member and the second connecting member sandwich and fix the peripheral portion and the connecting body, and the connecting body is in a position that does not overlap the peripheral portion, the second connecting member cannot be attached to the first connecting member, The dimensional relationship may be determined so that the second connecting member can be attached to the first connecting member when the connecting body is positioned so as to overlap the peripheral edge portion. According to this aspect, the second connecting member can be mounted only when the connecting body is in a predetermined position, and the positional relationship between the connecting body and the second connecting member after the mounting is less likely to vary depending on the installer, resulting in variations in construction quality. Can be suppressed satisfactorily.

また、前述の態様において、排水孔は、その内周を下方に垂下した垂下壁が形成され、連結体は、垂下壁が嵌合された嵌合部を有してもよい。この態様によれば、排水孔に対して連結体を容易に径方向に位置決めできる。よって、排水孔に対する連結体の径方向位置が施工者によりばらつき難くなり、施工品質のばらつきを抑えられる。   Moreover, in the above-mentioned aspect, the drainage hole may be formed with a hanging wall that hangs down on the inner periphery thereof, and the coupling body may have a fitting portion with which the hanging wall is fitted. According to this aspect, the connecting body can be easily positioned in the radial direction with respect to the drain hole. Therefore, the radial position of the coupling body with respect to the drain hole is less likely to vary by the installer, and variations in construction quality can be suppressed.

また、前述の態様において、排水孔の周縁部と連結体との間に配置されたスペーサーを更に備え、連結体は、スペーサーを間に挟んで周縁部と上下に重なるように配置されてもよい。この態様によれば、槽体の寸法条件に応じた寸法の複数種類のスペーサーを準備すればよく、槽体の寸法条件に応じて複雑な形状となり易い連結体の種類を増加させる必要がない。よって、寸法条件の異なる槽体に排水装置を接続するうえで、部材コストの増加を抑えられる。   Further, in the above-described aspect, a spacer may be further provided between the peripheral portion of the drain hole and the connection body, and the connection body may be disposed so as to overlap the peripheral portion with the spacer interposed therebetween. . According to this aspect, it is only necessary to prepare a plurality of types of spacers having dimensions corresponding to the dimensional conditions of the tank body, and there is no need to increase the types of connected bodies that tend to have complicated shapes according to the dimensional conditions of the tank body. Therefore, when connecting a drainage apparatus to the tank body from which a dimension condition differs, the increase in member cost can be suppressed.

また、本発明の別の態様は、排水装置の接続方法に関する。排水装置の接続方法は、槽体の底面部に排水装置を接続する方法であって、槽体の底面部に形成された排水孔の周縁部の下側に周縁部と上下に重なるように、排水装置の一部を構成する連結体を配置し、周縁部と連結体とを接続具により挟み込んで固定する。   Moreover, another aspect of the present invention relates to a method for connecting a drainage device. The connection method of the drainage device is a method of connecting the drainage device to the bottom surface portion of the tank body, and overlaps with the peripheral edge portion vertically below the peripheral edge portion of the drainage hole formed in the bottom surface portion of the tank body, A connecting body constituting a part of the drainage device is arranged, and the peripheral edge portion and the connecting body are sandwiched and fixed by a connecting tool.

この態様によれば、排水孔の周縁部と上下に重なるように連結体を配置するため、排水孔に連結体を容易に上下方向に位置決めできる。また、その位置決めした連結体と排水孔の周縁部とを接続具により挟み込んで固定するため、排水孔に対する連結体や接続具の上下位置が施工者によりばらつき難くなり、施工品質のばらつきが抑えられる。   According to this aspect, since the coupling body is disposed so as to overlap the peripheral edge of the drainage hole, the coupling body can be easily positioned in the vertical direction in the drainage hole. In addition, since the positioned connecting body and the peripheral portion of the drainage hole are sandwiched and fixed by the connecting tool, the vertical position of the connecting body and the connecting tool with respect to the drainage hole is less likely to be varied by the installer, and variation in construction quality can be suppressed. .

本発明によれば、槽体に排水装置を接続するにあたり、施工品質のばらつきを抑えられる。   According to this invention, when connecting a drainage device to a tank body, the dispersion | variation in construction quality can be suppressed.

When the upper connecting member 31 is in a locking position where the upper connecting member 31 is locked to the engaging wall 107 of the drainage hole 103 via the upper seal member 50, a part of the outer cylindrical portion 33 protrudes below the drainage hole 103. To do. A lower seal member 60 is attached to be wound around the outer peripheral side of the protruding outer cylinder portion 33.

連結体111を排水孔103の周縁部109に下側から近づけるように上側に向けて移動させる(S13)。連結体111は、その上側嵌合部113内に垂下壁105が嵌合されるように移動させる。連結体111は、その上側に隣り合う他部材(本実施形態では周縁部109)との間で、それらの上下に対向する面が接触するまで移動させる。このとき、下側シール部材60は、その径方向外側にまで連結体111の被固定部112が移動した時点で、その被固定部112の内周面と外筒部33の外周面とにより押し潰される。   The connecting body 111 is moved upward so as to approach the peripheral edge 109 of the drainage hole 103 from below (S13). The coupling body 111 is moved so that the hanging wall 105 is fitted in the upper fitting portion 113. The connecting body 111 is moved between other members adjacent to the upper side (peripheral portion 109 in the present embodiment) until their vertically opposed surfaces come into contact with each other. At this time, the lower seal member 60 is pushed by the inner peripheral surface of the fixed portion 112 and the outer peripheral surface of the outer cylindrical portion 33 when the fixed portion 112 of the coupling body 111 moves to the outside in the radial direction. It will be crushed.

上側接続部材31に下側接続部材41を装着する(S15)。本実施形態では、上側接続部材31の貫通孔33aに、複数の分割体43の係合部45を差し込んで下側接続部材41を装着する。各分割体43は、爪部43aを受け部43bに係合させて結合させる。   The lower connection member 41 is attached to the upper connection member 31 (S15). In the present embodiment, the lower connection member 41 is mounted by inserting the engaging portions 45 of the plurality of divided bodies 43 into the through holes 33 a of the upper connection member 31. Each divided body 43 is engaged with the claw portion 43a and joined to the receiving portion 43b.

ここで、ステップS11において、上側接続部材31の下側への移動量が不十分なため、図7(a)に示すように、上側接続部材31の下側係止部35が周縁部109に上側から係止されない非係止位置にある場合を考える。この場合、上側接続部材31の被係合部としての貫通孔33aの少なくとも一部が連結体111の底面より高位置にあり、その貫通孔33aに下側接続部材41の係合部45を差し込めない。一方、図7(c)に示すように、上側接続部材31が周縁部109に上側から係止される係止位置にある場合を考える。この場合、上側接続部材31の貫通孔33aが連結体111の底面より低位置にあり、下側接続部材41の係合部45を貫通孔33aに差し込める。   Here, in step S11, since the amount of downward movement of the upper connection member 31 is insufficient, as shown in FIG. Consider a case where the upper side is not locked from the upper side. In this case, at least a part of the through hole 33a as the engaged portion of the upper connecting member 31 is located higher than the bottom surface of the coupling body 111, and the engaging portion 45 of the lower connecting member 41 is inserted into the through hole 33a. Absent. On the other hand, as shown in FIG. 7C, a case is considered where the upper connecting member 31 is in a locking position where the upper edge connecting member 31 is locked from the upper side. In this case, the through hole 33a of the upper connection member 31 is located lower than the bottom surface of the coupling body 111, and the engaging portion 45 of the lower connection member 41 can be inserted into the through hole 33a.

また、ステップS13において、連結体111の上側への移動量が不十分なため、図7(b)に示すように、連結体111が周縁部109と上下に重ならない位置(以下、非重合位置という)にある場合を考える。非重合位置にある場合、連結体111は、上側に隣り合う他部材と接触しない。この場合も、上側接続部材31の貫通孔33aの少なくとも一部が連結体111の底面より高位置にあり、その貫通孔33aに下側接続部材41の係合部45を差し込めない。   Further, in step S13, since the amount of upward movement of the coupling body 111 is insufficient, as shown in FIG. 7B, the position where the coupling body 111 does not overlap with the peripheral edge 109 (hereinafter referred to as a non-polymerization position). )). When in the non-polymerization position, the coupling body 111 does not come into contact with other members adjacent to the upper side. Also in this case, at least a part of the through hole 33a of the upper connection member 31 is higher than the bottom surface of the coupling body 111, and the engaging portion 45 of the lower connection member 41 cannot be inserted into the through hole 33a.

一方、図7(c)に示すように、連結体111が周縁部109と上下に重なる位置(以下、重合位置という)にある場合を考える。この場合も、上側接続部材31の貫通孔33aが連結体111の下面より低位置にあり、下側接続部材41の係合部45を貫通孔33aに差し込める。   On the other hand, as shown in FIG. 7C, a case is considered in which the coupling body 111 is in a position (hereinafter referred to as a superposition position) that overlaps the peripheral edge portion 109 vertically. Also in this case, the through hole 33a of the upper connection member 31 is located lower than the lower surface of the coupling body 111, and the engaging portion 45 of the lower connection member 41 can be inserted into the through hole 33a.

つまり、上側接続部材31が非係止位置にある場合、または、連結体111が非重合位置にある場合、下側接続部材41の係合部45を貫通孔33aに差し込めず、上側接続部材31に下側接続部材41を装着不能となる。一方、上側接続部材31が係止位置にあり、かつ、連結体111が重合位置にある場合、下側接続部材41の係合部45を貫通孔33aに差し込め、上側接続部材31に下側接続部材41を装着可能となる。上側接続部材31、下側接続部材41及び連結体111は、このような条件を満たすように寸法関係が定められている。上側接続部材31に下側接続部材41を装着すると、連結体111と周縁部109とが接続具30により挟み込んで固定される。   That is, when the upper connection member 31 is in the non-locking position, or when the coupling body 111 is in the non-overlapping position, the engaging portion 45 of the lower connection member 41 cannot be inserted into the through hole 33a, and the upper connection member 31 is not inserted. The lower connection member 41 cannot be mounted. On the other hand, when the upper connection member 31 is in the locking position and the coupling body 111 is in the overlapping position, the engaging portion 45 of the lower connection member 41 is inserted into the through-hole 33a, and the lower connection to the upper connection member 31 is made. The member 41 can be attached. The upper connection member 31, the lower connection member 41, and the coupling body 111 have a dimensional relationship that satisfies such a condition. When the lower connection member 41 is attached to the upper connection member 31, the coupling body 111 and the peripheral edge 109 are sandwiched and fixed by the connection tool 30.

つづいて、連結体111の下側嵌合部115内に本体121の上端部121bが嵌合されるように、本体121を下側から上側に向けて移動させる(S17)。連結体111の上側フランジ部117に本体121の下側フランジ部127が当接したら、これらを留め具149により挟み込んで固定する。本体121と接続具30とが連結体111により繋がれる。   Subsequently, the main body 121 is moved from the lower side toward the upper side so that the upper end portion 121b of the main body 121 is fitted into the lower fitting portion 115 of the coupling body 111 (S17). When the lower flange portion 127 of the main body 121 comes into contact with the upper flange portion 117 of the coupling body 111, these are sandwiched and fixed by the fasteners 149. The main body 121 and the connection tool 30 are connected by the connecting body 111.

最後に、封水筒131の内筒部133を上側接続部材31の外筒部33内に挿通し、封水筒131の筒側嵌合部133bと接続具30の嵌合凸部37とを嵌合させて、排水孔103に対して封水筒131を上下に固定する(S19)。   Finally, the inner cylinder part 133 of the sealing cylinder 131 is inserted into the outer cylinder part 33 of the upper connection member 31, and the cylinder-side fitting part 133 b of the sealing cylinder 131 and the fitting convex part 37 of the connector 30 are fitted. The sealing tube 131 is fixed up and down with respect to the drain hole 103 (S19).

以上の接続構造10によれば、排水孔103の周縁部109と上下に重なるように連結体111を配置するため、排水孔103に連結体111を容易に上下方向に位置決めできる。また、その位置決めした連結体111と排水孔103の周縁部109とを接続具30により挟み込んで固定するため、排水孔103に対する連結体111や接続具30の上下位置が施工者によりばらつき難くなり、施工品質のばらつきが抑えられる。また、排水孔103の周縁部109と連結体111とを上下に重ねた状態で固定するため、連結体111が上下に強固に固定され、その連結体111に連結される排水装置110のがたつきを抑えられる。   According to the connection structure 10 described above, since the coupling body 111 is disposed so as to overlap the peripheral edge 109 of the drainage hole 103, the coupling body 111 can be easily positioned in the drainage hole 103 in the vertical direction. Further, since the positioned connecting body 111 and the peripheral edge 109 of the drainage hole 103 are sandwiched and fixed by the connecting tool 30, the vertical position of the connecting body 111 and the connecting tool 30 with respect to the drainage hole 103 is less likely to vary depending on the installer. Variations in construction quality can be suppressed. Further, since the peripheral portion 109 of the drainage hole 103 and the connecting body 111 are fixed in a state where they are vertically stacked, the connecting body 111 is firmly fixed in the vertical direction, and the drainage device 110 connected to the connecting body 111 has a backlash. You can suppress the date.

また、上述の接続構造10によれば、接続具30と周縁部109との間に上側シール部材50が配置され、接続具30と連結体111との間に下側シール部材60が配置され、これらが径方向両側から押し潰されている。シール部材を上下方向両側から押し潰す場合、シール部材の上下両側の部材の移動量を締め付け等により調整するにあたり、その上下両側の部材の間隔が施工誤差により大きく変動し、そのシール部材により所望のシール性を安定して得られない。一方、上述の接続構造10によれば、シール部材50、60を径方向両側から押し潰すため、その径方向両側の部材の間隔が施工誤差により変動し難く、それらシール部材50、60により、施工品質のばらつきを抑えて所望のシール性を得られる。   Further, according to the connection structure 10 described above, the upper seal member 50 is disposed between the connector 30 and the peripheral edge 109, and the lower seal member 60 is disposed between the connector 30 and the coupling body 111, These are crushed from both sides in the radial direction. When the seal member is crushed from both sides in the vertical direction, when adjusting the amount of movement of the upper and lower sides of the seal member by tightening or the like, the interval between the upper and lower sides of the seal member varies greatly due to construction errors. Sealability cannot be obtained stably. On the other hand, according to the connection structure 10 described above, since the seal members 50 and 60 are crushed from both sides in the radial direction, the interval between the members on the both sides in the radial direction is not easily changed due to construction errors. A desired sealing property can be obtained while suppressing the variation in quality.

また、上述の接続構造10によれば、上側接続部材31が係止位置にあり、かつ、連結体111が重合位置にある場合、上側接続部材31を下側接続部材41に装着可能とな。よって、上側接続部材31及び連結体111が所定位置にあるときにはじめて下側接続部材41を装着でき、その装着後の各部材の位置関係が施工者によりばらつき難くなり、施工品質のばらつきを良好に抑えられる。   Further, according to the connection structure 10 described above, the upper connection member 31 can be attached to the lower connection member 41 when the upper connection member 31 is in the locking position and the coupling body 111 is in the overlapping position. Therefore, the lower connection member 41 can be attached only when the upper connection member 31 and the coupling body 111 are in a predetermined position, and the positional relationship of each member after the attachment is less likely to vary by the installer, and the construction quality variation is good. Can be suppressed.

また、上述の接続構造10によれば、連結体111に垂下壁105が内側に嵌合される上側嵌合部113が設けられているため、排水孔103に対して連結体111を容易に径方向に位置決めできる。よって、排水孔103に対する連結体111の径方向位置が施工者によりばらつき難くなり、施工品質のばらつきを抑えられる。また、連結体111が径方向に強固に固定され、その連結体111に連結される排水装置110のがたつきを抑えられる。   Further, according to the connection structure 10 described above, the connecting body 111 is provided with the upper fitting portion 113 in which the hanging wall 105 is fitted inside, so that the connecting body 111 can be easily diametered with respect to the drain hole 103. Can be positioned in the direction. Therefore, the radial position of the coupling body 111 with respect to the drain hole 103 is less likely to vary by the installer, and variations in construction quality can be suppressed. Further, the coupling body 111 is firmly fixed in the radial direction, and rattling of the drainage device 110 coupled to the coupling body 111 can be suppressed.

なお、貫通孔33aは、図4(a)に示すように、その底面が排水孔103の周方向に沿って設けられた受け面33bとして構成される。また、係合部45は、その下面が受け面33bに沿うように形成され、受け面33bに面接触するように係合されている。下側接続部材41に作用する荷重が上側接続部材31に安定して伝達し易くなり、下側接続部材41に取り付けられる排水装置110の本体121ががたつき難くなる。   As shown in FIG. 4A, the bottom surface of the through-hole 33a is configured as a receiving surface 33b provided along the circumferential direction of the drainage hole 103. Further, the engaging portion 45 is formed so that the lower surface thereof is along the receiving surface 33b, and is engaged so as to come into surface contact with the receiving surface 33b. A load acting on the lower connection member 41 is easily and stably transmitted to the upper connection member 31, and the main body 121 of the drainage device 110 attached to the lower connection member 41 is difficult to rattle.

また、上側接続部材31の貫通孔33aと、この貫通孔33aに係合される下側接続部材41の係合部45とは、排水孔103の周方向に等角度間隔を空けた箇所に位置するように複数組配置される。図示の例では、これらが排水孔103の周方向に4組設けられるように、等角度間隔を空けた箇所に位置するように配置される。下側接続部材41に作用する荷重が上側接続部材31に安定して伝達し易くなり、下側接続部材41に取り付けられる排水装置110の本体121ががたつき難くなる。   In addition, the through hole 33 a of the upper connection member 31 and the engagement portion 45 of the lower connection member 41 engaged with the through hole 33 a are located at positions spaced equiangularly in the circumferential direction of the drain hole 103. A plurality of sets are arranged so as to. In the example shown in the figure, these are arranged so as to be located at equiangular intervals so that four sets are provided in the circumferential direction of the drainage hole 103. A load acting on the lower connection member 41 is easily and stably transmitted to the upper connection member 31, and the main body 121 of the drainage device 110 attached to the lower connection member 41 is difficult to rattle.

また、封水筒131は、その内側に周方向に間隔を空けて板状の複数の摘み部131dが設けられる。図3では一つの摘み部131dのみを図示する。ユーザーは、摘み部131dを把持した状態で封水筒131を移動等させて、接続具30の外筒部33から封水筒131を抜き出せる。   In addition, the sealing tube 131 is provided with a plurality of plate-shaped knobs 131d at intervals on the inner side thereof in the circumferential direction. FIG. 3 shows only one knob 131d. The user can move the seal tube 131 while holding the knob 131 d to extract the seal tube 131 from the outer tube portion 33 of the connector 30.

また、下側接続部材41の筒状部42には、上側接続部材31の下面と対向する支持部42cが設けられる。支持部42cは、上側接続部材31の外筒部33の形状に合わせた形状、つまり、環状に形成され、その上面に上側接続部材31の下面が接触する。上側接続部材31に下側接続部材41を装着するとき、この支持部42cを上側接続部材31の下面に接触させると、上側接続部材31に対する下側接続部材41の位置合せをし易くなり、その装着時の作業性が良好となる。また、支持部42cが上側接続部材31の下面に接触するため、上側接続部材31に対する下側接続部材41の固定度が増し、連結体111等の排水装置110が上下方向に揺れ動こうとしたとき、その揺れ動きが効果的に抑えられる。   In addition, the cylindrical portion 42 of the lower connection member 41 is provided with a support portion 42 c that faces the lower surface of the upper connection member 31. The support part 42c is formed in a shape corresponding to the shape of the outer cylinder part 33 of the upper connection member 31, that is, in an annular shape, and the lower surface of the upper connection member 31 is in contact with the upper surface thereof. When the lower connecting member 41 is mounted on the upper connecting member 31, if the support portion 42c is brought into contact with the lower surface of the upper connecting member 31, the lower connecting member 41 can be easily aligned with the upper connecting member 31, Workability at the time of mounting becomes good. Moreover, since the support part 42c contacts the lower surface of the upper side connection member 31, the fixing degree of the lower side connection member 41 with respect to the upper side connection member 31 increases, and the drainage apparatus 110, such as the coupling body 111, tried to swing up and down. Sometimes the shaking is effectively suppressed.

[第2の実施の形態]
図8は、第2実施形態に係る排水装置110の接続構造10を示す。本実施形態では、第1実施形態と比較して、接続構造10にスペーサー70が含まれる点が主に相違する。以下、第1実施形態で説明した要素と同一の要素に同一の符号を付し、重複する説明を省略する。
[Second Embodiment]
FIG. 8 shows the connection structure 10 of the drainage device 110 according to the second embodiment. The present embodiment is mainly different from the first embodiment in that the connection structure 10 includes a spacer 70. Hereinafter, the same reference numerals are given to the same elements as those described in the first embodiment, and a duplicate description is omitted.

槽体100は、第1実施形態と比較して、その素材がステンレス等の金属材料により構成され、その肉厚が薄くなるように構成される。   The tank body 100 is configured such that the material is made of a metal material such as stainless steel and the thickness thereof is thinner than that of the first embodiment.

スペーサー70は、排水孔103の周縁部109と連結体111との間に配置される。スペーサー70は、下側重合部71と、スペーサー側嵌合部73と、上側重合部75とを含んで構成される。スペーサー70は、樹脂等の硬質材料を素材としており、これらが一体成形されている。   The spacer 70 is disposed between the peripheral edge 109 of the drain hole 103 and the coupling body 111. The spacer 70 includes a lower overlapping portion 71, a spacer side fitting portion 73, and an upper overlapping portion 75. The spacer 70 is made of a hard material such as a resin, and these are integrally molded.

下側重合部71は、環状に形成され、その内側に挿通孔71aが形成される。挿通孔71aには上側接続部材31の外筒部33が挿通される。スペーサー側嵌合部73は、下側重合部71の上側において、上方に開口して下方に窪む凹みとして設けられる。上側重合部75は、スペーサー70の上部において下側重合部71より径方向外側に設けられる。   The lower overlapping portion 71 is formed in an annular shape, and an insertion hole 71a is formed inside thereof. The outer cylindrical portion 33 of the upper connection member 31 is inserted through the insertion hole 71a. The spacer-side fitting portion 73 is provided as a recess that opens upward and is recessed downward on the upper side of the lower overlapping portion 71. The upper overlapping portion 75 is provided on the outer side in the radial direction from the lower overlapping portion 71 above the spacer 70.

スペーサー70は、スペーサー側嵌合部73の内側に垂下壁105が嵌合される。連結体111は、スペーサー70を間に挟んで上側嵌合部113の内側に垂下壁105が嵌合される。   In the spacer 70, the hanging wall 105 is fitted inside the spacer-side fitting portion 73. In the coupling body 111, the hanging wall 105 is fitted inside the upper fitting portion 113 with the spacer 70 interposed therebetween.

スペーサー70の下側重合部71及び上側重合部75と周縁部109とは、上下に隣り合うように設けられ、互いに上下に対向する面が接触する。スペーサー70の下側重合部71及び上側重合部75と連結体111とは、上下に隣り合うように設けられ、互いに上下に対向する面が接触する。つまり、スペーサー70は、上下に隣り合う排水孔103の周縁部109や連結体111との間で、それらの上下に対向する面を接触させた状態で、上下に重なるように配置される。また、連結体111は、このスペーサー70の下側重合部71及び上側重合部75を間に挟んで周縁部109と上下に重なるように配置される。このとき、連結体111は、上側に隣り合う他部材(スペーサー70)との間で、それらの上下に対向する面を接触させた状態となる。   The lower overlapping portion 71 and the upper overlapping portion 75 of the spacer 70 and the peripheral edge portion 109 are provided so as to be adjacent to each other in the vertical direction, and surfaces facing each other in the vertical direction are in contact with each other. The lower overlapping portion 71 and the upper overlapping portion 75 of the spacer 70 and the coupling body 111 are provided so as to be adjacent to each other in the vertical direction, and surfaces facing each other in the vertical direction contact each other. That is, the spacer 70 is disposed so as to overlap vertically with the vertically opposed surfaces 109 and the coupling body 111 in contact with the vertically opposed surfaces thereof. Further, the coupling body 111 is disposed so as to overlap the peripheral portion 109 with the lower overlapping portion 71 and the upper overlapping portion 75 interposed therebetween. At this time, the coupling body 111 is in a state where the upper and lower surfaces thereof are brought into contact with another member (spacer 70) adjacent to the upper side.

以上の接続構造10の作用効果を説明する。槽体100は、その厚みや底面部101の傾き等の寸法条件が様々である。このため、排水孔103の周縁部109と上下に重なるように連結体111を配置するため、槽体100の寸法条件に応じた寸法の複数種の連結体111を準備すると、連結体111が複雑な形状となり易いため、部材コストの大幅な増大を招く。一方、本実施形態に係る接続構造10によれば、その槽体100の寸法条件に応じた寸法の複数種のスペーサー70を準備すればよく、槽体100の寸法条件に応じて連結体111の種類を増加させる必要がない。よって、寸法条件の異なる槽体100に排水装置110を接続するうえで、部材コストの増加を抑えられる。   The effect of the above connection structure 10 is demonstrated. The tank body 100 has various dimensional conditions such as thickness and inclination of the bottom surface portion 101. For this reason, in order to arrange the connection body 111 so that it may overlap with the peripheral part 109 of the drainage hole 103, if the several types of connection body 111 of the dimension according to the dimensional condition of the tank body 100 is prepared, the connection body 111 will be complicated. Therefore, the member cost is greatly increased. On the other hand, according to the connection structure 10 according to the present embodiment, a plurality of types of spacers 70 having dimensions corresponding to the dimensional conditions of the tank body 100 may be prepared. There is no need to increase the variety. Therefore, an increase in member cost can be suppressed when connecting the drainage device 110 to the tank body 100 having different dimensional conditions.

以上、実施の形態に基づき本発明を説明したが、実施の形態は、本発明の原理、応用を示すにすぎない。また、実施の形態には、請求の範囲に規定された本発明の思想を逸脱しない範囲において、多くの変形例や配置の変更が可能である。   As mentioned above, although this invention was demonstrated based on embodiment, embodiment only shows the principle and application of this invention. In the embodiment, many modifications and arrangements can be made without departing from the spirit of the present invention defined in the claims.

上述の実施形態に係る排水装置110は、封水筒131を用いた排水トラップを説明したが、排水装置110は、封水筒131が用いられていなくともよく、Sトラップ、椀トラップ等の排水トラップにより構成されてもよい。また、排水装置110は、槽体100の排水孔103から流れた水を外部に排出できればよく、排水トラップとして構成されていなくともよい。   Although the drainage device 110 according to the above-described embodiment has been described as a drainage trap using the sealing tube 131, the drainage device 110 may not use the sealing tube 131, and may be a drainage trap such as an S trap or a trap. It may be configured. Moreover, the drainage device 110 should just be able to discharge | emit the water which flowed from the drainage hole 103 of the tank body 100 outside, and does not need to be comprised as a drainage trap.

また、排水装置110の連結体111は、本体121と別体に設けられた例を説明した。しかし、連結体111は、少なくとも接続具30に本体121を繋ぐことができるものとして設けられていればよく、連結体111と本体121が一体成形により一体に設けられてもよい。また、排水装置110の連結体111と本体121とは、上側フランジ部117と下側フランジ部127とを留め具149により挟み込んで固定する例を説明したが、その固定方法は、これに限定されず、この他にもボルトナット等を用いて固定してもよい。   In addition, the example in which the connecting body 111 of the drainage device 110 is provided separately from the main body 121 has been described. However, the coupling body 111 is only required to be connected to at least the connector 30 so that the main body 121 can be connected, and the coupling body 111 and the main body 121 may be integrally formed by integral molding. Moreover, although the connection body 111 and the main body 121 of the drainage apparatus 110 demonstrated the example which pinches | interposes and fixes the upper side flange part 117 and the lower side flange part 127 with the fastener 149, the fixing method is limited to this. In addition, you may fix using a volt | bolt nut etc. besides this.

排水孔103は、垂下壁105と、係合壁107とを含むものを説明したが、係合壁107が含められていなくともよい。また、排水孔103は、垂下壁105と係合壁107との両方を含んでいなくともよい。この場合、接続具30は、上側接続部材31の下側係止部35を排水孔103の上端縁103a周りの環状部分101bに係止させてもよい。   Although the drain hole 103 has been described as including the hanging wall 105 and the engaging wall 107, the engaging wall 107 may not be included. Further, the drainage hole 103 may not include both the hanging wall 105 and the engaging wall 107. In this case, the connection tool 30 may lock the lower locking portion 35 of the upper connection member 31 to the annular portion 101 b around the upper edge 103 a of the drain hole 103.
