特開平１０−１８５０２０（図２）JP-A-10-185020 (FIG. 2)

しかしながら上記従来例には、以下に記載するような問題点があった。
１．上記排水器本体やインナー継手本体等の継手本体とナット部材からなる継手部材において、ナット部材を継手本体側に配置するためには、継手本体の、鍔部を備えない側の端部からナット部材を挿通し、通常鍔部近傍まで移動させなければならない。ところが、このようにナット部材を継手本体の鍔部近傍まで移動させても、ナット部材は接続対象となる部材の雄ネジ部と螺合するまで、継手本体上（場合によってはホース管等継手本体が接続されている部材を含む）継手本体の軸方向に自由に移動できる状態に維持されるため、例えば施工作業のため継手本体を上方に向ける際に、注意しなければナット部材は継手本体及びホース管から容易に脱落してしまい、破損したり、そのまま紛失してしまうという問題があった。ナット部材を挿通した後、継手本体側に寄せた上で、ホース管を結んでしまえば上記問題はある程度解決できるが、これはホース管のような可撓性のある部材が、それなりの長さで用意されている場合にしか採用できない上、工場側でホース管を結ぶ手間が、施工現場では結び目をほどく手間が、それぞれ増加する。また、ホース管には無理な曲げ方を共用することもあり、ホース管の形状に曲がりクセが付くなど、部材管理上にも問題がある。
２．ナット部材を継手本体に接続する場合において、ナット部材を継手本体に取り付けようとしたとき、ナット部材が継手本体に対して１乃至１０度程度傾いてしまうと、傾斜の反対側でネジピッチ数個分の誤差となって、ネジの螺合がうまく進まないことがあった。ナット部材と継手本体との接続固定は、必ずしもネジによって行う必要は無いが、ネジ以外の方法で接続するにせよ、ナット部材が継手本体に対して傾斜した状態では、接続固定が適正に行うことができない場合が多い、という問題があった。
３．継手本体が平面視円形を成し自由に回転できるような構成の場合において、継手本体の側面部分に排出口等の部材構成を備えることで方向性を有することがある。このような継手本体をシンクなどの槽体に取り付ける場合、継手本体の方向を調整した上で取り付けを行う必要がある。しかし、この時は方向調整を行った後でナット部材を継手本体に通過させる必要がある（ナット部材に螺合など固定作業を行うと、当然ながら固定は完了してしまい、方向を調整する事はできない。しかし固定作業を行わなければ、ナット部材は支えを失って継手本体から落下する）。このナット部材の挿通時にナット部材が継手本体に誤って接触してしまうと、継手本体の位置や方向がずれ、方向調整が狂う場合があり、再度方向調整の作業を繰り返す必要がある、という問題があった。 However, the conventional example has the following problems.
1. In order to arrange the nut member on the joint body side in the joint member including the joint body such as the drainage body and the inner joint body and the nut member, the nut member is arranged from the end of the joint body on the side not provided with the flange portion. It must be moved to the vicinity of the buttocks. However, even if the nut member is moved to the vicinity of the flange portion of the joint body in this way, the nut member remains on the joint body (in some cases, the joint body such as a hose pipe) until the nut member is screwed with the male thread portion of the member to be connected. (Including the member to which the nut is connected) is maintained in a state where it can freely move in the axial direction of the joint body. For example, when turning the joint body upward for construction work, There is a problem that the hose pipe easily falls off and is damaged or lost as it is. The above problem can be solved to some extent by connecting the hose tube after inserting the nut member and then moving it to the joint body side. This is because a flexible member such as a hose tube has a certain length. In addition, it can be used only when it is prepared by the factory, and the labor for connecting the hose pipe at the factory side and the labor for unwinding the knot at the construction site are increased. In addition, the hose pipe may share an unreasonable bending method, and the hose pipe has a problem in terms of member management, such as bending the shape of the hose pipe.
2. When connecting the nut member to the joint body, when the nut member is attached to the joint body, if the nut member is tilted about 1 to 10 degrees with respect to the joint body, several screw pitches on the opposite side of the slope Due to this error, screwing of the screw did not progress well. Connection and fixing of the nut member and the joint body do not necessarily have to be performed with screws, but connection and fixing should be performed properly when the nut member is tilted with respect to the joint body, even if it is connected by a method other than screws. There was a problem that there were many cases where it was not possible.
3. In the case where the joint body has a circular shape in plan view and can be freely rotated, the joint body may have directionality by providing a member structure such as a discharge port on the side surface portion. When attaching such a joint body to a tank body such as a sink, it is necessary to perform attachment after adjusting the direction of the joint body. However, at this time, after adjusting the direction, it is necessary to pass the nut member through the joint body (if fixing work such as screwing onto the nut member is performed, the fixing is naturally completed and the direction must be adjusted. However, if the fixing work is not performed, the nut member loses its support and falls from the joint body). If the nut member accidentally comes into contact with the joint body when the nut member is inserted, the position and direction of the joint body may be misaligned, which may cause the direction adjustment to go wrong, and it is necessary to repeat the direction adjustment work again. was there.

例えば図１９に示したインナー継手本体のように、継手本体を２パーツに分け、鍔部を軸方向に複数設けてナット部材を挟みこむように接着固定すれば、上記の問題は解決できるが、この場合、継手本体を２パーツ以上に分け、更に接着する必要があるため、部材単価及び製造上の手間が相当に増すこととなる、といった問題があった。
本発明は上記問題点を解消するために考案されたものであり、継手部材において、安価且つ容易にナット部材の接続作業を行うことができるものとしつつ、継手本体からナット部材が脱落することを防止する、継手部材を提供するものである。 For example, like the inner joint body shown in FIG. 19, if the joint body is divided into two parts and a plurality of flanges are provided in the axial direction and the nut member is sandwiched and fixed, the above problem can be solved. In this case, there is a problem in that the joint body is divided into two or more parts and needs to be further bonded, so that the unit cost of the member and the labor for manufacturing are considerably increased.
The present invention has been devised in order to solve the above-mentioned problems. In the joint member, the nut member can be detached from the joint body while the nut member can be connected easily and inexpensively. A joint member to prevent is provided.

本発明の管体の接続部材は、以下の効果を奏する。
１．請求項１、請求項４に記載の本発明は、弾性係止部の弾性を利用して、ナット部材を、継手本体に仮止め状態とすることができるため、ナット部材が継手本体から脱落することが無い。このため、部材破損や紛失、また工場などでホース管等を結んだり、施工現場で結び目をほどく、といった手間の掛かることなく、良好な配管接続を行うことができる。
また、弾性係止部を管体と一体に成型することで、部材単価を下げ、また作業工程から弾性係止部を管体に接着する等の作業を省くことができる。更に弾性係止部は使用の際弾性を発揮するために応力が加えられるものであり、接着などの方法では強度不足によって接着箇所が外れるなどの可能性があり、これを防ぐためビス止めなど強固な固定方法を採用する必要が生じる場合がある。これに対して、一体成型では弾性を保ちつつ且つ強度も確保できるという優れた効果を奏する。
２．請求項２に記載の本発明は、弾性係止部が、外側面に、鍔部に向かうほど内側に向かう傾斜面を備えてなることで、ナット部材を挿通する際、傾斜面がガイドとして機能し、弾性係止部に弾性を生じさせて縮径させ、挿通しやすくする効果を生じる。
３．請求項３に記載の本発明は、弾性係止部が、外側面に、鍔部に向かうほど外側に向かう傾斜面を備えてなることで、傾斜面によってナット部材が鍔部側に付勢される事となり、ナット部材が弾性係止部と鍔部の間で移動してカタカタと騒音を生じたりする事がない。また、ナット部材を鍔部に付勢させているため、接続作業が容易となる。例えばネジによる螺合でナット部材の接続を行う場合、ナット部材をただ回転させるだけで螺合させることができ、施工をより一層容易にすることができる。
４．請求項５に記載の本発明は、弾性係止部が、内側面に、端部は段部よりも内側方向に位置し、且つ鍔部に向かうほど内側に向かう傾斜面を備えてなることで、継手本体上を鍔部に向かって挿通する際、弾性係止部に弾性を生じさせて拡径させ、挿通しやすくする効果を生じる。
５．請求項６に記載の本発明は、弾性係止部が、内側面に、端部は段部よりも外側方向に位置し、且つ鍔部に向かうほど内側に向かう傾斜面を備えてなることで、傾斜面によってナット部材が鍔部側に付勢される事となり、ナット部材が弾性係止部と鍔部の間で移動してカタカタと騒音を生じたりする事がない。また、ナット部材を鍔部に付勢させているため、接続作業が容易となる。例えばネジによる螺合でナット部材の接続を行う場合、ナット部材をただ回転させるだけで螺合させることができ、施工をより一層容易にすることができる。
６．請求項７乃至請求項９に記載の本発明では、本発明の具体的な構造を明確にすることができる。 The connecting member of the tubular body of the present invention has the following effects.
1. According to the first and fourth aspects of the present invention, since the nut member can be temporarily fixed to the joint body by using the elasticity of the elastic locking portion, the nut member falls off the joint body. There is nothing. For this reason, it is possible to make a good pipe connection without taking the trouble of damaging or losing the member, tying a hose pipe or the like at the factory, or unzipping the knot at the construction site.
In addition, by molding the elastic locking portion integrally with the tube, it is possible to reduce the unit cost of the member and to omit work such as bonding the elastic locking portion to the tube from the work process. In addition, the elastic locking part is stressed in order to exert elasticity during use, and there is a possibility that the bonded part will come off due to insufficient strength in the method such as adhesion, and in order to prevent this, it is strong such as screwing It may be necessary to adopt a proper fixing method. On the other hand, the integral molding has an excellent effect of maintaining the elasticity and ensuring the strength.
2. According to the second aspect of the present invention, when the elastic locking portion is provided with an inclined surface on the outer side surface that goes inward as it goes toward the flange portion, the inclined surface functions as a guide when the nut member is inserted. Then, elasticity is generated in the elastic locking portion to reduce the diameter, thereby producing an effect of facilitating insertion.
3. According to the third aspect of the present invention, the elastic locking portion is provided with an inclined surface on the outer side surface that goes outward as it goes toward the flange portion, so that the nut member is urged toward the flange portion by the inclined surface. Therefore, the nut member does not move between the elastic locking portion and the flange portion and does not generate a rattling noise. Moreover, since the nut member is urged toward the flange portion, the connection work is facilitated. For example, when the nut member is connected by screwing with a screw, the nut member can be screwed only by rotating, and the construction can be further facilitated.
4). The present invention according to claim 5 is that the elastic locking portion is provided with an inclined surface on the inner side surface, the end portion is positioned inward of the stepped portion, and is directed inward toward the flange portion. When inserting the joint main body toward the flange, the elastic locking part is elastically expanded to increase the diameter, thereby facilitating the insertion.
5). In the present invention according to claim 6, the elastic locking portion is provided with an inclined surface on the inner side surface, the end portion is located on the outer side of the stepped portion, and the inner surface is directed toward the flange portion. The nut member is urged toward the flange portion by the inclined surface, and the nut member does not move between the elastic locking portion and the flange portion to cause rattling and noise. Moreover, since the nut member is urged toward the flange portion, the connection work is facilitated.

ナット部材４は、断面Ｌ字形状を成す環状の部材であって、内面側に雌ネジ部６を備えると共に、内面側の下端に、内周縁に沿って連続した当接部４ａを備えてなる（このように、雌ネジ部６のある内側に向かって当接部４ａを設けてなるナット部材４を「袋ナット」と呼ぶ）。尚、当接部４ａによって形成される円形状の開口部４ｂは、鍔部２の外周円よりも小径の円形状を成す。 A first embodiment of the present invention will be described below with reference to the drawings.
The drainage pipe of the first embodiment of the present invention shown in FIG. 1 to FIG. 5 is constituted by each member such as a drainage body 8, a hose pipe 9, an inner joint body 1 as a joint body, and a nut member 4. Become. The structure of each member is described below.
The drainage body 8 is a bottomed cylindrical member having a circular shape in plan view, and is made of a relatively hard resin such as polypropylene, and has a drainage port 10 for collecting drainage inside the sink S described later. At the same time, the bottom surface is provided with a discharge port 11 for discharging the waste water from the drain port 10.
The hose tube 9 is a member formed of a flexible soft resin in a cylindrical shape, and a core made of a wire or the like is spirally formed in order to maintain flexibility while maintaining flexibility inside the hose tube 9. Prepare.
The inner joint body 1 is a member for connecting the hose pipe 9 and the drainage body 8 and has a cylindrical shape, and has a flange portion 2 that protrudes outwardly continuously along the periphery on the upper end side, An annular packing P is provided at the upper end of the flange 2. Further, a cylindrical portion inserted into the hose pipe 9 is provided below.
Furthermore, the inner joint main body 1 of the first embodiment has an elastic locking piece 3a provided on the side surface of the inner joint main body 1 and having elasticity, and its end side is reduced in diameter toward the center of the tube by elasticity. And a claw portion 3b provided on the outer surface of the elastic locking piece 3a, provided at the tip of the elastic locking piece 3a, with a first inclined surface 3c that goes outward as it goes toward the flange portion 2. The locking part 3 is provided integrally.
The nut member 4 is an annular member having an L-shaped cross section, and includes a female screw portion 6 on the inner surface side and a contact portion 4a continuous along the inner periphery at the lower end on the inner surface side. (As described above, the nut member 4 provided with the contact portion 4a toward the inner side with the female screw portion 6 is referred to as a “cap nut”). The circular opening 4b formed by the abutting portion 4a has a circular shape with a smaller diameter than the outer peripheral circle of the flange portion 2.

上記の各部材から構成された接続継手は、以下のようにして使用・施工される。
まず工場にて継手本体の円筒部分の周囲に接着剤を塗布し、そのホース管９を外嵌させて接着固定する。
次に、図１に示したように、ホース管９の、継手本体を備えた端部とは反対側の端部からナット部材４を挿通する。
更にナット部材４を継手本体側に挿通してゆくと、図２に示したように、ナット部材４の開口が弾性係止部３の爪部３ｂの第一傾斜面３ｃにさしかかる。この時は、図２乃至図３に示したように、開口部４ｂが第一傾斜面３ｃ上を通過し、それに併せて弾性係止片３ａが内側に撓むことでナット部材４が挿通してゆく。ナット部材４の開口部４ｂが完全に第一傾斜面３ｃを通過すると、弾性によって弾性係止片３ａが復帰し、図４に示したように、ナット部材４の開口より爪部３ｂの外縁の方が外側に飛び出してナット部材４が爪部３ｂより抜脱する事を防止する。前述のように、ナット部材４の円形状の開口部４ｂは、鍔部２の外周円よりも小径の円形状を成すため、弾性係止部３の弾性係止片３ａを意図的に撓めない限り、ナット部材４の当接部４ａが、インナー継手本体１の鍔部２と爪部３ｂの間から外れることはない。
この状態にて工場よりホース部材を出荷し、施工現場に搬入する。
施工現場にて、排水器本体８の排出口１１にインナー継手本体１のパッキンＰを同心円状に当接させつつ、ナット部材４の雌ネジ部６を排出口１１の雄ネジ部７に螺号させると、図５に示したように、パッキンＰが排出口１１の開口に強く当接した状態で、鍔部２下面が、当接部４ａ上面に当接して固定され、排水器本体８の排出口１１に水密的に固定され、排水器本体８へのインナー継手本体１との接続固定が完了する。 The connection joint comprised from said each member is used and constructed as follows.
First, an adhesive is applied around the cylindrical portion of the joint body at the factory, and the hose tube 9 is externally fitted and fixed.
Next, as shown in FIG. 1, the nut member 4 is inserted from the end of the hose pipe 9 opposite to the end provided with the joint body.
When the nut member 4 is further inserted into the joint body side, the opening of the nut member 4 reaches the first inclined surface 3c of the claw portion 3b of the elastic locking portion 3 as shown in FIG. At this time, as shown in FIGS. 2 to 3, the opening 4b passes over the first inclined surface 3c, and the elastic locking piece 3a is bent inward at the same time, so that the nut member 4 is inserted. Go. When the opening 4b of the nut member 4 completely passes through the first inclined surface 3c, the elastic locking piece 3a is restored by elasticity, and the outer edge of the claw portion 3b is opened from the opening of the nut member 4 as shown in FIG. This prevents the nut member 4 from popping out and the nut member 4 being pulled out from the claw portion 3b. As described above, since the circular opening 4b of the nut member 4 has a circular shape having a smaller diameter than the outer peripheral circle of the flange portion 2, the elastic locking piece 3a of the elastic locking portion 3 is intentionally bent. As long as there is not, the contact part 4a of the nut member 4 will not remove | deviate from between the collar part 2 and the nail | claw part 3b of the inner joint main body 1. FIG.
In this state, the hose member is shipped from the factory and carried to the construction site.
At the construction site, the packing P of the inner joint body 1 is brought into concentric contact with the discharge port 11 of the drainage device main body 8, and the female screw portion 6 of the nut member 4 is screwed to the male screw portion 7 of the discharge port 11. As shown in FIG. 5, with the packing P in strong contact with the opening of the discharge port 11, the bottom surface of the flange portion 2 is fixed in contact with the top surface of the contact portion 4a. It is fixed to the outlet 11 in a watertight manner, and the connection and fixing with the inner joint body 1 to the drainage body 8 is completed.

上記第一実施例においては、弾性係止部３の弾性を利用して、ナット部材４（の当接部４ａ）を、継手本体であるインナー継手本体１に設けた鍔部２と弾性係止部３の間に配置・係止する事ができるため、単にナット部材４を挿通するだけで、継手本体からの脱落を防止することができ、従来例のように、工場などでホース管９等を結んだり、施工現場で結び目をほどく、といった手間の掛かることなく、良好な配管接続を行うことができる。
また、挿通作業も弾性係止部３の爪部３ｂに設けた第一傾斜面３ｃによって、単にナット部材４をインナー継手本体１の鍔部２側に押し通すだけで良く、弾性係止部３を手作業で撓ませるなどする必要がない。
また、弾性係止部３は継手本体に一体に成型されてなるため、接着などの手間が掛からず、また弾性を確保するために細くする必要がある場合でもそれなりの強度を確保でき、部材の破損の心配が少ない。また部材単価を下げる効果も併せて生じている。 In the first embodiment, using the elasticity of the elastic locking portion 3, the nut member 4 (the contact portion 4a thereof) is elastically locked to the flange portion 2 provided on the inner joint main body 1 which is a joint main body. Since it can be arranged and locked between the portions 3, it can be prevented from falling off the joint body simply by inserting the nut member 4, and the hose tube 9 etc. at the factory etc. as in the conventional example Good pipe connections can be made without the hassle of tying up or untied the knot at the construction site.
Further, the insertion work can be performed by simply pushing the nut member 4 toward the flange 2 side of the inner joint body 1 by the first inclined surface 3c provided on the claw portion 3b of the elastic locking portion 3. There is no need to bend it manually.
In addition, since the elastic locking portion 3 is formed integrally with the joint body, it does not take time and effort such as adhesion, and even when it is necessary to make it thin in order to ensure elasticity, it can ensure a certain strength. There is little worry about damage. In addition, the effect of lowering the unit price is also generated.

次に、本発明の第二実施例を、図面を参照しつつ説明する。
図６乃至図１０に示した本発明の第二実施例の排水配管は、継手本体としての排水器本体８と、ナット部材４と、それらが取り付けられる流し台のシンクＳ等の各部材より構成されてなる。以下に各部材の構造を記す。
排水器本体８は平面視円形をなす有底円筒状の部材であって、ポリプロピレン等の比較的硬質の樹脂からなり、その内部に後述するシンクＳ内部の排水を集水する排水口１０を備えると共に、該排水口１０の開口周縁に、外方向に向かって連続して突出した鍔部２を備えてなり、側面の、底面近傍部分には排水口１０からの排水を排出する排出口１１を備えてなる。
また、排水器本体８の鍔部２の下面には円環状にして平坦なパッキンを、その更に下方であって排水器本体の外側面には、排水器本体８の外周面に沿って雄ネジ部７を備えてなる。
更に上記排水器本体８には、雄ネジ部７の下方となる側面に、排水器本体８の中心を挟んで対称となる位置に、断面略への字を９０度回転させた形状をなす弾性係止部３を２つ備えてなる。
該弾性係止部３は、上方側の一端が、管体である排水器本体８の雄ネジ部７の下方に一体に成型した形で備えられてなり、下方側のもう一端はいずれにも接続されることなくそのまま開放された状態に備えられてなる。このとき、略くの字を成す事で備えられる傾斜面の内、
外側面であって、下側に備えられた、鍔部２に向かうほど外側に向かう傾斜面を第一傾斜面３ｃ、上側に備えられた、鍔部２に向かうほど内側に向かう傾斜面を第二傾斜面３ｄとする。
上述のように、弾性係止部３の下方の端部は開放されてなるため、弾性係止部３のへの字形状は、外側から内側に向かう応力が加えられると、下方に伸びるようにして平坦に近づき、応力が失われると弾性により元の形状に戻る。
ナット部材４は、断面Ｌ字形状を成す環状の部材であって、内面側に雌ネジ部６を備えると共に、外側面の上端に、外側面に沿って連続した当接部４ａを備えてなる（このように、外側面方向に向かって板状の当接部４ａを設けてなるナット部材４を「板ナット」と呼ぶ）。尚、当接部４ａによって形成される円形状の開口は、後述するシンクＳの取付孔よりも大径の円弧を成す。
上記各部材が取り付けられる流し台のシンクＳは、上方が開放された箱体形状をなし、その底面に、排水器本体８の鍔部２外周縁よりも小径で、雄ネジ部７よりも大径な取付孔を設けてなる。 Next, a second embodiment of the present invention will be described with reference to the drawings.
The drainage pipe according to the second embodiment of the present invention shown in FIGS. 6 to 10 is composed of a drainage body 8 as a joint body, a nut member 4, a sink S and the like of a sink to which they are attached. It becomes. The structure of each member is described below.
The drainage body 8 is a bottomed cylindrical member having a circular shape in plan view, and is made of a relatively hard resin such as polypropylene, and has a drainage port 10 for collecting drainage inside the sink S described later. At the same time, the peripheral edge of the drain opening 10 is provided with a flange 2 continuously projecting outward, and a discharge port 11 for discharging drainage from the drain port 10 is provided on the side surface and in the vicinity of the bottom surface. Prepare.
In addition, an annular and flat packing is provided on the lower surface of the flange portion 2 of the drainage device main body 8, and a male screw is provided on the outer surface of the drainage device main body along the outer peripheral surface of the drainage device body 8. Part 7 is provided.
Further, the drainage body 8 has an elastic shape in which the shape of the cross-sectional shape is rotated 90 degrees on the side surface below the male screw portion 7 at a symmetrical position across the center of the drainage body 8. Two locking portions 3 are provided.
The elastic locking portion 3 is provided with an upper end integrally formed below the male threaded portion 7 of the drainage body 8 that is a tubular body, and the other end on the lower side is in any case. It is provided in a state of being opened as it is without being connected. At this time, out of the inclined surface provided by forming an abbreviated letter,
A first inclined surface 3c is an outer side surface, which is provided on the lower side and is directed to the outer side as it goes toward the collar part 2, and an inclined surface which is provided on the upper side and is directed toward the inner side as it is directed to the collar part 2. Let it be two inclined surfaces 3d.
As described above, since the lower end portion of the elastic locking portion 3 is opened, the U-shape of the elastic locking portion 3 extends downward when stress from the outside to the inside is applied. When the stress is lost, it returns to its original shape due to elasticity.
The nut member 4 is an annular member having an L-shaped cross section, and includes a female screw portion 6 on the inner surface side and a contact portion 4a continuous along the outer surface at the upper end of the outer surface. (Thus, the nut member 4 provided with the plate-like contact portion 4a toward the outer surface direction is referred to as a “plate nut”). The circular opening formed by the abutting portion 4a forms an arc having a larger diameter than the mounting hole of the sink S described later.
The sink S of the sink to which each member is attached has a box shape with the top opened, and has a diameter smaller than that of the outer peripheral edge of the flange portion 2 of the drainage body 8 and larger than that of the male screw portion 7 on the bottom surface. A mounting hole is provided.

上記の各部材から構成された接続継手は、以下のようにして使用・施工される。
尚、通常シンクＳへの排水器本体８の取り付けは工場内にて行われるものであり、以下の施工作業も本実施例では全て工場内にて行われるものとする。
まず取付孔に排水器本体８を上方から挿通し、鍔部の下面が、パッキンを介して取付孔周縁の上面に当接するようにする。
次に、図６に示したように、ナット部材４を、ナット部材４の当接部４ａを上方に向けた状態で、排水器本体８の下方から挿通する。
更にナット部材４を上昇させると、弾性係止部３は排水器本体８との接続部分、及び略くの字形状の折れ曲がり部分が撓み、図７から図８の過程を経て、弾性係止部３が下方に伸びるようにして平坦に近づき、その分内側への突出が減少してナット部材４を上方に挿通する事ができる。ナット部材４の雄ネジ部７が、弾性係止部３の第一傾斜面３ｃを越え、第二傾斜面３ｄにさしかかると、図９に示したように、弾性係止部３が弾性により当初の形状に戻ろうとする応力（排水器本体８の外側方向に拡がろうとする応力）が第二傾斜面３ｄの作用によって、方向を変換され、ナット部材４を上方に押し上げる応力となる。このため、ナット部材４内周面の雌ネジ部６上端が、排水器本体８の雄ネジ部７の下端に押し当てられ、螺合を行うことなく、仮止め状態として、排水器本体８にナット部材４を係止することができる。
この状態から、ナット部材４を回転させると、排水器本体８の雄ネジ部７が、ナット部材４の雌ネジ部６に螺合して、排水器本体８の鍔部２と、ナット部材４の当接部４ａとで、シンクＳの取付孔周縁を挟持する事となり、図１０に示したように排水器本体８が槽体であるシンクＳに水密的に固定され、シンクＳへの排水器本体８との接続固定が完了する。 The connection joint comprised from said each member is used and constructed as follows.
In addition, the attachment of the drainage device main body 8 to the normal sink S is performed in the factory, and the following construction work is also performed in the factory in this embodiment.
First, the drainage device main body 8 is inserted into the mounting hole from above, and the lower surface of the flange is brought into contact with the upper surface of the peripheral edge of the mounting hole via the packing.
Next, as shown in FIG. 6, the nut member 4 is inserted from below the drainage device body 8 with the contact portion 4 a of the nut member 4 facing upward.
When the nut member 4 is further raised, the elastic locking portion 3 is bent at the connecting portion with the drainage body 8 and the bent portion of the substantially U-shape, and the elastic locking portion 3 goes through the process of FIGS. 3 becomes flat as it extends downward, and the protrusion to the inside decreases accordingly, so that the nut member 4 can be inserted upward. When the male thread portion 7 of the nut member 4 passes over the first inclined surface 3c of the elastic locking portion 3 and reaches the second inclined surface 3d, the elastic locking portion 3 is initially elastically elastic as shown in FIG. The stress that tends to return to the shape (stress that tends to spread outward in the drainage body 8) is changed in direction by the action of the second inclined surface 3d, and becomes a stress that pushes the nut member 4 upward. For this reason, the upper end of the female threaded portion 6 on the inner peripheral surface of the nut member 4 is pressed against the lower end of the male threaded portion 7 of the drainage device main body 8, and is temporarily attached to the drainage device body 8 without screwing. The nut member 4 can be locked.
When the nut member 4 is rotated from this state, the male screw portion 7 of the drainage device main body 8 is screwed into the female screw portion 6 of the nut member 4, and the flange portion 2 of the drainage device main body 8 and the nut member 4. The abutment portion 4a sandwiches the periphery of the mounting hole of the sink S. As shown in FIG. 10, the drainer body 8 is watertightly fixed to the sink S that is a tank body, and the drainage to the sink S is performed. The connection and fixing with the container body 8 is completed.

上記のような継手部材において、ナット部材４は、螺子ピッチが直径が１乃至２ミリメートル程度、全高は２０ミリメートル前後に対し、直径は１８０乃至２００ミリメートルと、螺子ピッチや全高に対して直径がかなり大きい。このため、ナット部材４を排水器本体８に取り付けようとしたとき、ナット部材４が排水器本体８に対して１乃至１０度程度傾いてしまうと、傾斜の反対側で螺子ピッチ数個分の誤差となって、螺子の螺合がうまく進まないことがあった。これに対して、上記した第二実施例の、弾性係止部３を採用した排水器本体８の場合、上記のように、第二傾斜面３ｄの作用によりナット部材４が上方に押圧されるようになるため、ナット部材４の雌ネジ部６が、排水器本体８の雄ネジ部７に対して傾斜することが無くなり、ナット部材４を回転させるだけで容易に接続させることができる。 In the joint member as described above, the nut member 4 has a screw pitch of about 1 to 2 millimeters, an overall height of about 20 millimeters, and a diameter of 180 to 200 millimeters, which is considerably larger than the screw pitch and overall height. large. For this reason, when the nut member 4 is to be attached to the drainage body 8 when the nut member 4 is tilted about 1 to 10 degrees with respect to the drainage body 8, several screw pitches are provided on the opposite side of the slope. Due to an error, screwing of the screw may not proceed well. On the other hand, in the case of the drainage body 8 adopting the elastic locking portion 3 of the second embodiment described above, the nut member 4 is pressed upward by the action of the second inclined surface 3d as described above. Therefore, the female screw portion 6 of the nut member 4 is not inclined with respect to the male screw portion 7 of the drainage body 8 and can be easily connected only by rotating the nut member 4.

また、排水器本体８は、上記実施例の排出口１１等、側面部分に何らかの部材構成を備えることで方向性を有することがある。このような排水器本体８をシンクＳなどの槽体に取り付ける場合、排水器本体８の方向を調整した上で取り付けを行う必要があるが、弾性係止部３を備えない排水器本体８の場合、ナット部材４を仮止め状態とすることができないため、方向調整を行った後、ナット部材４を排水器本体８に通過させる必要がある。このナット部材４の挿通時にナット部材４が排水器本体８に誤って接触してしまうと、排水器本体８の位置がずれ、方向調整が狂う場合がある。これに対し、上記実施例のように、弾性係止部３を利用して排水器本体８にナット部材４を仮止めできる場合、ナット部材４を排水器本体８に挿通し、弾性係止部３に係止させて仮止めした上で方向調整を行うことで、方向調整終了後、ナット部材４を排水器本体８に挿通させることなく、そのまま排水器本体８の雄ネジ部７に、ナット部材４の雌ネジ部６を螺合させることができる。ナット部材４を排水器本体８に通過させる必要が無くなり、挿通時のナット部材４が排水器本体８に誤って接触してしまう、という事が無くなるため、施工時の作業の信頼性が向上する。 Moreover, the drainage device main body 8 may have directionality by providing a certain member configuration on a side surface portion such as the discharge port 11 of the above embodiment. When attaching such a drainage device body 8 to a tank body such as a sink S, it is necessary to perform the installation after adjusting the direction of the drainage device body 8, but the drainage device body 8 not provided with the elastic locking portion 3. In this case, since the nut member 4 cannot be temporarily fixed, it is necessary to pass the nut member 4 through the drainage body 8 after adjusting the direction. If the nut member 4 accidentally contacts the drainage device main body 8 when the nut member 4 is inserted, the position of the drainage device main body 8 may be shifted and the direction adjustment may be incorrect. On the other hand, when the nut member 4 can be temporarily fixed to the drainage body 8 using the elastic locking portion 3 as in the above-described embodiment, the nut member 4 is inserted into the drainage body 8 and the elastic locking portion. 3 and then temporarily fixing the nut member 4 to the male threaded portion 7 of the drainage device body 8 without inserting the nut member 4 into the drainage device body 8 after the direction adjustment is completed. The female screw portion 6 of the member 4 can be screwed together. There is no need to pass the nut member 4 through the drainage device main body 8, and the nut member 4 at the time of insertion does not accidentally come into contact with the drainage device main body 8, so that the reliability of work during construction is improved. .

次に、本発明の第三実施例を、図面を参照しつつ説明する。
図１１乃至図１５に示した本発明の第三実施例の排水配管は、継手本体としての排水器本体８と、ナット部材４と、それらが取り付けられる流し台のシンクＳ等の各部材より構成されてなる。以下に各部材の構造を記す。
排水器本体８は平面視円形をなす有底円筒状の部材であって、ポリプロピレン等の比較的硬質の樹脂からなり、その内部に後述するシンクＳ内部の排水を集水する排水口１０を備えると共に、該排水口１０の開口周縁に、外方向に向かって連続して突出した鍔部２を備えてなり、側面の、底面近傍部分には排水口１０からの排水を排出する排出口１１を備えてなる。
また、排水器本体８の鍔部２の下面には円環状にして平坦なパッキンを、その更に下方であって排水器本体の外側面には、排水器本体８の外周面に沿って雄ネジ部７を備えてなる。
更に上記排水器本体８には、雄ネジ部７の下方となる側面に、排水器本体８の外周面に沿って、鍔部２側が内側に向かう段差を生じる段部５を備えてなる。
ナット部材４は、断面Ｌ字形状を成す環状の部材であって、内面側に雌ネジ部６を備えると共に、外側面の上端に、外側面に沿って連続した当接部４ａを備えてなる（このように、外側面方向に向かって板状の当接部４ａを設けてなるナット部材４を「板ナット」と呼ぶ）。尚、当接部４ａによって形成される円形状の開口は、後述するシンクＳの取付孔よりも大径の円弧を成す。
更にナット部材４の下端部分には、ナット部材４の中心軸を挟んで対称となる位置に、断面略への字を９０度回転させた形状をなす弾性係止部３を２つ備えてなる。
該弾性係止部３は、上方側の一端が、ナット部材４の下方に一体に成型した形で備えられてなり、下方側のもう一端はいずれにも接続されることなくそのまま開放された状態に備えられてなる。このとき、略くの字を成す事で備えられる傾斜面の内、内側面であって、下側に備えられた、鍔部２に向かうほど内側に向かう傾斜面を第三傾斜面３ｅ、上側に備えられた、鍔部２に向かうほど外側に向かう傾斜面を第四傾斜面３ｆとする。
上述のように、弾性係止部３の下方の端部は開放されてなるため、弾性係止部３のへの字形状は、内側から外側に向かう応力が加えられると、弾性により外側方向に曲がるように屈曲し、応力が失われると弾性により元の形状に戻る。
上記各部材が取り付けられる流し台のシンクＳは、上方が開放された箱体形状をなし、その底面に、排水器本体８の鍔部２外周縁よりも小径で、雄ネジ部７よりも大径な取付孔を設けてなる。 Next, a third embodiment of the present invention will be described with reference to the drawings.

Further, the drainage body 8 is provided with a step portion 5 on the side surface below the male screw portion 7 along the outer peripheral surface of the drainage body 8 to generate a step toward the inside of the flange 2 side.
The nut member 4 is an annular member having an L-shaped cross section, and includes a female screw portion 6 on the inner surface side and a contact portion 4a continuous along the outer surface at the upper end of the outer surface. (Thus, the nut member 4 provided with the plate-like contact portion 4a toward the outer surface direction is referred to as a “plate nut”). The circular opening formed by the abutting portion 4a forms an arc having a larger diameter than the mounting hole of the sink S described later.
Further, the lower end portion of the nut member 4 is provided with two elastic locking portions 3 having a shape obtained by rotating a substantially square shape by 90 degrees at a position symmetrical with respect to the central axis of the nut member 4. .
The elastic locking portion 3 is provided with an upper end integrally formed below the nut member 4, and the lower end is opened as it is without being connected to any of them. Be prepared for. At this time, among the inclined surfaces provided by forming an abbreviated letter, the third inclined surface 3e is provided on the inner side surface of the inclined surface, which is provided on the lower side and goes inward as it goes to the flange 2. The fourth inclined surface 3f is an inclined surface that is provided toward the outer side as it goes toward the flange 2.
As described above, since the lower end portion of the elastic locking portion 3 is opened, the shape of the elastic locking portion 3 is changed to the outer side due to elasticity when a stress from the inside to the outside is applied. It bends so that it bends, and when stress is lost, it returns to its original shape due to elasticity.
The sink S of the sink to which each member is attached has a box shape with the top opened, and has a diameter smaller than that of the outer peripheral edge of the flange portion 2 of the drainage body 8 and larger than that of the male screw portion 7 on the bottom surface. A mounting hole is provided.

上記の各部材から構成された接続継手は、以下のようにして使用・施工される。
尚、通常シンクＳへの排水器本体８の取り付けは工場内にて行われるものであり、以下の施工作業も本実施例では全て工場内にて行われるものとする。
まず取付孔に排水器本体８を上方から挿通し、鍔部の下面が、パッキンを介して取付孔周縁の上面に当接するようにする。
次に、図１１に示したように、ナット部材４を、ナット部材４の当接部４ａを上方に向けた状態で、排水器本体８の下方から挿通する。
更にナット部材４を上昇させると、ナット部材４の上昇に伴い弾性係止部３も上昇し、第四傾斜面３ｆが排水器本体８の下端に接する。この時、図１３に示したように、上昇するために働く力の作用の一部が、第四傾斜面３ｆの作用によって、方向を変換され、弾性傾斜部を外側に押し開く応力となる。弾性傾斜部が、排水器本体８上を挿通するのに充分なだけ押し開かれると、そのままナット部材４を鍔部２の方向に上昇させることができる。
ナット部材４の弾性傾斜部の第四傾斜面３ｆが段部５を越え、第三傾斜面３ｅが段部５にさしかかると、図１４に示したように、弾性係止部３が弾性により当初の形状に戻ろうとする応力（ナット部材４の内側方向に縮径しようとする応力）が第三傾斜面３ｅの作用によって、方向を変換され、ナット部材４を上方に押し上げる応力となる。このため、ナット部材４内周面の雌ネジ部６上端が、排水器本体８の雄ネジ部７の下端に押し当てられ、螺合を行うことなく、仮止め状態として、排水器本体８にナット部材４を係止することができる。
この状態から、ナット部材４を回転させると、排水器本体８の雄ネジ部７が、ナット部材４の雌ネジ部６に螺合して、排水器本体８の鍔部２と、ナット部材４の当接部４ａとで、シンクＳの取付孔周縁を挟持する事となり、図１５に示したように排水器本体８が槽体であるシンクＳに水密的に固定され、シンクＳへの排水器本体８との接続固定が完了する。 The connection joint comprised from said each member is used and constructed as follows.
In addition, the attachment of the drainage device main body 8 to the normal sink S is performed in the factory, and the following construction work is also performed in the factory in this embodiment.
First, the drainage device main body 8 is inserted into the mounting hole from above, and the lower surface of the flange is brought into contact with the upper surface of the peripheral edge of the mounting hole via the packing.
Next, as shown in FIG. 11, the nut member 4 is inserted from below the drainage device body 8 with the contact portion 4 a of the nut member 4 facing upward.
When the nut member 4 is further raised, the elastic locking portion 3 is also raised as the nut member 4 is raised, and the fourth inclined surface 3 f is in contact with the lower end of the drainage body 8. At this time, as shown in FIG. 13, a part of the action of the force that works to ascend is changed in direction by the action of the fourth inclined surface 3 f and becomes a stress that pushes the elastic inclined part outward. When the elastic inclined portion is pushed open enough to be inserted over the drainage body 8, the nut member 4 can be lifted in the direction of the flange 2 as it is.
When the fourth inclined surface 3f of the elastic inclined portion of the nut member 4 exceeds the stepped portion 5 and the third inclined surface 3e reaches the stepped portion 5, as shown in FIG. The stress to return to the shape (stress to reduce the diameter in the inner direction of the nut member 4) is changed in direction by the action of the third inclined surface 3e, and becomes a stress that pushes the nut member 4 upward. For this reason, the upper end of the female threaded portion 6 on the inner peripheral surface of the nut member 4 is pressed against the lower end of the male threaded portion 7 of the drainage device main body 8, and is temporarily attached to the drainage device body 8 without screwing. The nut member 4 can be locked.
When the nut member 4 is rotated from this state, the male screw portion 7 of the drainage device main body 8 is screwed into the female screw portion 6 of the nut member 4, and the flange portion 2 of the drainage device main body 8 and the nut member 4. The abutment portion 4a sandwiches the periphery of the mounting hole of the sink S. As shown in FIG. 15, the drainer body 8 is watertightly fixed to the sink S that is a tank body, and the drainage to the sink S is performed. The connection and fixing with the container body 8 is completed.

上記のような継手部材において、ナット部材４は、螺子ピッチが直径が１乃至２ミリメートル程度、全高は２０ミリメートル前後に対し、直径は１８０乃至２００ミリメートルと、螺子ピッチや全高に対して直径がかなり大きい。このため、ナット部材４を排水器本体８に取り付けようとしたとき、ナット部材４が排水器本体８に対して１乃至１０度程度傾いてしまうと、傾斜の反対側で螺子ピッチ数個分の誤差となって、螺子の螺合がうまく進まないことがあった。これに対して、上記した第三実施例の、弾性係止部３を採用した排水器本体８の場合、上記のように、第三傾斜面３ｅの作用によりナット部材４が上方に押圧されるようになるため、ナット部材４の雌ネジ部６が、排水器本体８の雄ネジ部７に対して傾斜することが無くなり、ナット部材４を回転させるだけで容易に接続させることができる。 In the joint member as described above, the nut member 4 has a screw pitch of about 1 to 2 millimeters, an overall height of about 20 millimeters, and a diameter of 180 to 200 millimeters, which is considerably larger than the screw pitch and overall height. large. For this reason, when the nut member 4 is to be attached to the drainage body 8 when the nut member 4 is tilted about 1 to 10 degrees with respect to the drainage body 8, several screw pitches are provided on the opposite side of the slope. Due to an error, screwing of the screw may not proceed well. On the other hand, in the case of the drainage body 8 adopting the elastic locking portion 3 in the third embodiment described above, the nut member 4 is pressed upward by the action of the third inclined surface 3e as described above. Therefore, the female screw portion 6 of the nut member 4 is not inclined with respect to the male screw portion 7 of the drainage body 8 and can be easily connected only by rotating the nut member 4.

また、本第三実施例に記載した継手部材は、上記第二実施例の段落００２１に記載した効果も有してなる。 Further, the joint member described in the third embodiment also has the effect described in paragraph 0021 of the second embodiment.

本発明の実施例は以上のようであるが本発明は上記実施例に限定される物ではなく、主旨を変更しない範囲において自由に変更が可能である。例えば、上記実施例では、継手本体とナット部材４をネジによる螺合で接続してなるが、本発明は上記実施例に限定されるものではなく、ネジ以外の接続構造、例えば実開平２−４２９７４（丸一レバー式カチットの実用新案）に記載されたようなレバー部材を利用した接続構造を採用することができる。この場合、排水器本体８やインナー継手本体１、またナット部材４は必ずしも円形状を形成する必要はなくなるなどのメリットも有してなる。 The embodiments of the present invention are as described above. However, the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention. For example, in the above-described embodiment, the joint body and the nut member 4 are connected by screwing with a screw. However, the present invention is not limited to the above-described embodiment. A connection structure using a lever member as described in 42974 (utility model of a round-one lever type gusset) can be employed. In this case, the drainage body 8, the inner joint body 1, and the nut member 4 have merits such as not necessarily having to form a circular shape.
