Description

本発明は、浴槽洗浄用ノズルなどの流体器具とホースなどの配管部材との接続を図るための流体器具配管接続構造に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid device piping connection structure for connecting a fluid device such as a bathtub cleaning nozzle and a piping member such as a hose.

本出願人は、浴槽の底部に取付けられて使用され、かつ浴槽の内側に向けて洗浄水を噴射することにより浴槽を洗浄するための浴槽洗浄用ノズルを提案している（特許文献１を参照）。このような浴槽洗浄用ノズルには、洗浄水を供給するための配管部材を抜け止め状態に接続する必要がある。その一方、浴槽洗浄用ノズルは、浴槽底部と、その下方と浴室床面との間に形成されているスペースに設置しなければならないが、このスペースは、上下高さ方向の幅がかなり狭い場合が多い。したがって、浴槽洗浄用ノズルと配管部材との接続部は、上下高さ方向にできる限り嵩張らないようにすることが要望される。 The present applicant has proposed a bathtub cleaning nozzle that is attached to the bottom of a bathtub and used to clean the bathtub by spraying washing water toward the inside of the bathtub (see Patent Document 1). ). A piping member for supplying cleaning water must be connected to such a bathtub cleaning nozzle in a manner that prevents it from coming off. On the other hand, the bathtub cleaning nozzle must be installed in the space formed between the bottom of the bathtub and the bottom of the bathtub and the floor of the bathroom. There are many. Therefore, it is desired that the connecting portion between the bathtub cleaning nozzle and the piping member be as small as possible in the vertical direction.

一方、従来においては、配管接続手段として、簡易な止め具を用いて抜け止めを図るものなど、種々の構造の継手が提案されている（たとえば、特許文献２～４など）。
しかしながら、これら従来の継手は、いずれも配管部材の外周囲の全体にわたって嵩張ったものとなり易く、横幅のみならず、縦幅も比較的大きい構造となる。これでは、狭小スペースに設置する用途に余り適しない。 On the other hand, conventionally, as pipe connection means, joints with various structures have been proposed, such as one that uses a simple stopper to prevent the pipe from coming off (for example, Patent Documents 2 to 4, etc.).
However, these conventional joints tend to be bulky over the entire outer circumference of the piping member, and have a structure that is relatively large not only in width but also in length. This is not very suitable for installation in narrow spaces.

本発明は、前記したような事情のもとで考え出されたものであり、浴槽洗浄用ノズルなどの流体器具と配管部材との接続部の薄型化を図り、狭小スペースへの設置などに適したものとすることが可能な流体器具配管接続構造を提供することを、その課題としている。 The present invention has been conceived under the circumstances described above, and aims to reduce the thickness of the connecting portion between a fluid device such as a bathtub cleaning nozzle and a piping member, and is suitable for installation in a narrow space. An object of the present invention is to provide a fluid device piping connection structure that can be used as a fluid device.

上記の課題を解決するため、本発明では、次の技術的手段を講じている。 In order to solve the above problems, the present invention takes the following technical means.

本発明により提供される流体器具配管接続構造は、継手用筒状部を有する流体器具と、前記継手用筒状部に一端部が嵌合した状態で前記流体器具に接続される配管部材と、この配管部材の外面部に装着され、前記配管部材の軸長方向への移動を規制する止め具と、を備えている、流体器具配管接続構造であって、前記流体器具の前記継手用筒状部からその横幅方向両側へ張り出すように設けられ、かつ前記継手用筒状部の軸長方向に隙間を隔てて相互に対向する左右一対ずつの第１および第２のストッパ壁部と、前記止め具に前記横幅方向両側へ張り出すように設けられ、かつ前記継手用筒状部に対する前記止め具の前記軸長方向への移動が規制されるように、前記第１および第２のストッパ壁部の相互間の前記隙間に配される左右一対の突出部と、をさらに備えており、前記止め具は、帯状金属板を用いて形成され、かつ一部に形成された開口部の幅が拡縮可能なバネ性を有する二股状の部材であって、前記配管部材の周囲を取り囲むようにして前記配管部材にその外方側から装着可能であるとともに、前記左右一対の突出部が屈曲状部分として一体的に形成されている部材であり、前記一対の第２のストッパ壁部は、一対の側壁部を介して前記一対の第１のストッパ壁部に繋がり、かつ前記隙間の前記横幅方向両側は、前記一対の側壁部により閉塞されており、前記一対ずつの第１および第２のストッパ壁部の上部または下部には、前記止め具が前記配管部材周りに一定以上回転することを阻止するように、前記一対の突出部に当接可能な一対の第３のストッパ壁部が設けられており、前記隙間のうち、前記一対の第３のストッパ壁部とは反対側の下部または上部は、開口しており、この開口箇所から前記止め具を前記隙間に挿入させて前記配管部材の外面部に装着可能な構成とされていることを特徴としている。
本発明において、前記流体器具は、浴槽に取付けられ、かつこの浴槽に洗浄水を噴射するための浴槽洗浄用ノズル、またはその構成部品である構成とすることができる。 A fluid device pipe connection structure provided by the present invention includes a fluid device having a joint tubular portion; a piping member connected to the fluid device with one end fitted to the joint tubular portion; and a stopper that is attached to the outer surface of the piping member and restricts movement of the piping member in the axial direction. a pair of left and right first and second stopper wall portions which are provided so as to protrude from the joint cylindrical portion to both sides in the lateral width direction thereof and are opposed to each other with a gap in the axial direction of the joint cylindrical portion; The first and second stopper walls are provided on the stopper so as to protrude on both sides in the lateral width direction and restrict the movement of the stopper with respect to the joint tubular portion in the axial direction. a pair of left and right protrusions disposed in the gap between the parts , the stopper is formed using a strip-shaped metal plate, and the width of the opening formed in a part is A bifurcated member having elastic properties that can be expanded and contracted, and is attachable to the piping member from the outer side so as to surround the circumference of the piping member, and the pair of left and right protrusions are curved portions. The pair of second stopper wall portions are connected to the pair of first stopper wall portions via a pair of side wall portions, and both sides of the gap in the width direction is closed by the pair of side walls, and the top or bottom of each pair of the first and second stopper walls prevents the stopper from rotating around the piping member more than a certain amount. , a pair of third stopper wall portions that can abut on the pair of projecting portions are provided, and the lower or upper portion of the gap on the side opposite to the pair of third stopper wall portions is , through which the fastener can be inserted into the gap and attached to the outer surface of the piping member .
In the present invention, the fluid device may be a bathtub cleaning nozzle attached to a bathtub and for injecting washing water into the bathtub, or a component thereof.

このような構成によれば、流体器具に設けられた第１および第２のストッパ壁部と、止め具の突出部とが係合するため、流体器具と配管部材とを抜け止めなどが図られた適切な状態に接続できることに加え、次のような効果がさらに得られる。
流体器具の継手用筒状部に設けられた第１および第２のストッパ壁部は、継手用筒状部の横幅方向へ張り出しており、また止め具の突出部も、同様な方向に張り出した形態であって、前記第１および第２のストッパ壁部の相互間の隙間に配されている。このため、継手用筒状部および止め具の双方を、縦幅方向に嵩張らないものとすることができる。その結果、流体器具と配管部材との接続部全体の縦幅を小さくし、流体器具および配管部材を狭小スペースに設置するのに適したものとすることが可能である。
さらに、流体器具と配管部材との接続をより安定させたものとすることができる。すなわち、本発明では、流体器具の継手用筒状部の横幅方向の片側のみに張り出した第１および第２のストッパ壁部を設けた構成とし、全体をさらに小サイズ化することも可能であるものの、これでは左右のバランスがよいとは言えない。これに対し、前記構成によれば、第１および第２のストッパ壁部、および止め具の突出部が、左右一対ずつで設けられているため、左右のバランスをよくし、流体器具と配管部材との接続を安定させ、また強度を高めることもできる。
さらに、止め具が配管部材周りに大きく回転した場合には、止め具の突出部が第１および第２のストッパ壁部の相互間の隙間から脱出し、流体器具と配管部材との抜け止め状態が解除される虞がある。これに対し、前記構成によれば、止め具が配管部材周りに大きく回転することを防止することができるために、前記した虞を適切に回避することが可能である。 According to such a configuration, since the first and second stopper wall portions provided on the fluid device and the projecting portion of the stopper are engaged with each other, it is possible to prevent the fluid device and the piping member from coming off. In addition to being able to connect in an appropriate state, the following effects can be obtained.
The first and second stopper walls provided on the joint tubular portion of the fluid device protrude in the lateral width direction of the joint tubular portion, and the protruding portion of the stopper also protrudes in the same direction. and is arranged in a gap between the first and second stopper walls. Therefore, both the joint tubular portion and the stopper can be made compact in the longitudinal width direction. As a result, it is possible to reduce the overall vertical width of the connecting portion between the fluid device and the piping member, making it suitable for installing the fluid device and the piping member in a narrow space.
Furthermore, the connection between the fluid device and the piping member can be made more stable. That is, in the present invention, it is possible to further reduce the overall size by providing the first and second stopper walls projecting only on one side in the lateral width direction of the coupling cylindrical portion of the fluid device. However, it cannot be said that the left and right balance is good with this. On the other hand, according to the above configuration, since the first and second stopper wall portions and the projecting portion of the stopper are provided in pairs on the left and right sides, the balance between the left and right sides is improved, and the fluid device and the piping member are well balanced. It can also stabilize the connection with and increase the strength.
Further, when the stopper rotates largely around the piping member, the projecting portion of the stopper escapes from the gap between the first and second stopper wall portions, preventing the fluid device and the piping member from coming off. is likely to be released. On the other hand, according to the above configuration, since it is possible to prevent the stopper from largely rotating around the piping member, it is possible to appropriately avoid the above-described concerns.

本発明において、好ましくは、前記第１および第２のストッパ壁部、ならびに前記止め具のそれぞれの縦幅は、前記継手用筒状部の縦幅以下とされている。 In the present invention, preferably, the vertical width of each of the first and second stopper wall portions and the stopper is equal to or less than the vertical width of the joint tubular portion.

このような構成によれば、流体器具と配管部材との接続部において、第１および第２のストッパ壁部や止め具が、継手用筒状部の外周面よりも縦幅方向にはみ出した状態にはならないようにすることができる。したがって、流体器具と配管部材との接続部の縦幅を嵩張らないようにする上で、より好ましいものとなる。 According to such a configuration, in the connecting portion between the fluid device and the piping member, the first and second stopper wall portions and the stopper protrude in the longitudinal and width directions from the outer peripheral surface of the tubular joint portion. can be prevented from becoming Therefore, it is more preferable to keep the vertical width of the connection between the fluid device and the piping member from becoming bulky.

本発明のその他の特徴および利点は、添付図面を参照して以下に行なう発明の実施の形態の説明から、より明らかになるであろう。 Other features and advantages of the present invention will become clearer from the following description of embodiments of the invention with reference to the accompanying drawings.

以下、本発明の好ましい実施の形態について、図面を参照して具体的に説明する。 Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

図１および図２に示す流体器具配管接続構造Ａは、本発明でいう「流体器具」の一例に相当する浴槽洗浄用ノズル１、この浴槽洗浄用ノズル１に洗浄水を供給するための配管部材２、および止め具３を具備している。本実施形態の流体器具配管接続構造Ａは、浴槽洗浄用ノズル１の接続構造として構成されている。 The fluid device piping connection structure A shown in FIGS. 1 and 2 includes a bathtub cleaning nozzle 1 corresponding to an example of the "fluid device" of the present invention, and a piping member for supplying cleaning water to the bathtub cleaning nozzle 1. 2, and a stop 3. The fluid device pipe connection structure A of this embodiment is configured as a connection structure for a bathtub cleaning nozzle 1 .

浴槽洗浄用ノズル１は、後述するノズル受け１１の構成を除き、特許文献１に記載されたもの同様な構成である。すなわち、この浴槽洗浄用ノズル１は、ノズル本体部１０がノズル受け１１に支持された構成であり、浴槽の底壁部８に取付けて使用される。配管部材２からノズル受け１１内に洗浄水が供給されてくると、この洗浄水は、ノズル本体部１０から浴槽の内面に向けて噴射され、このことにより浴槽の洗浄がなされる。 The bathtub cleaning nozzle 1 has the same configuration as that described in Patent Document 1, except for the configuration of the nozzle receiver 11, which will be described later. That is, the bathtub cleaning nozzle 1 has a structure in which a nozzle main body 10 is supported by a nozzle receiver 11, and is attached to the bottom wall 8 of the bathtub for use. When washing water is supplied from the piping member 2 into the nozzle receiver 11, the washing water is jetted from the nozzle body 10 toward the inner surface of the bathtub, thereby washing the bathtub.

ノズル受け１１は、合成樹脂製であり、その一端側には、略水平方向に延びる継手用筒状部１２が一体形成されている。図１（ｃ）および図２によく表れているように、継手用筒状部１２の先端部には、左右一対ずつの第１ないし第３のストッパ壁部１３ａ～１３ｃが設けられている。一対の第１のストッパ壁部１３ａは、継手用筒状部１２の外周面からノズル受け１１の横幅方向両側へ部分的に膨出した壁部である。一対の第２のストッパ壁部１３ｂは、一対の第１のストッパ壁部１３ａよりも継手用筒状部１２の先端側に隙間９を介して対面する壁部である。各第２のストッパ壁部１３ｂは、側壁部１４を介して各第１のストッパ壁部１３ａに繋がっており、これらは、図１（ｃ）に示すように、底面視略コ字状の形態に繋がっている。各第３のストッパ壁部１３ｃは、第１および第２のストッパ壁部１３ａ，１３ｂの上部どうしを部分的に繋ぐように設けられた壁部であり、隙間９の上側を閉塞している（図１（ｂ）を参照）。ただし、第３のストッパ壁部１３ｃは、第１および第２のストッパ壁部１３ａ，１３ｂの下部どうしを繋ぐように設けることも可能である。 The nozzle receptacle 11 is made of synthetic resin, and one end side thereof is integrally formed with a joint tubular portion 12 extending in a substantially horizontal direction. As shown in FIGS. 1(c) and 2, the distal end portion of the joint cylindrical portion 12 is provided with first to third stopper wall portions 13a to 13c in pairs on the left and right sides. The pair of first stopper walls 13 a are walls that partially bulge from the outer peripheral surface of the joint tubular portion 12 toward both sides in the width direction of the nozzle receiver 11 . The pair of second stopper wall portions 13b is a wall portion that faces the distal end side of the joint cylindrical portion 12 through the gap 9 from the pair of first stopper wall portions 13a. Each second stopper wall portion 13b is connected to each first stopper wall portion 13a via a side wall portion 14. As shown in FIG. connected to Each third stopper wall portion 13c is a wall portion provided so as to partially connect the upper portions of the first and second stopper wall portions 13a and 13b, and closes the upper side of the gap 9 ( See FIG. 1(b)). However, the third stopper wall portion 13c can also be provided so as to connect the lower portions of the first and second stopper wall portions 13a and 13b.

配管部材２は、ホース２０の先端部に、補助管体２１が装着された構成である。補助管体２１は、シール用Ｏリング２２が装着され、かつ止め具３の係止装着用の環状凹溝２３が外周面に形成された部材である。この補助管体２１は、ホース２０の先端部に抜け止め状態に固定連結されているが、その手段としては、たとえばホース２０に外嵌されている薄手の金属製筒状部材２４をその半径方向に圧縮してカシメることにより、ホース２０の先端部を補助管体２１に圧接させるといった手段が採用されている。
配管部材２の補助管体２１の先端部は、浴槽洗浄用ノズル１（ノズル受け１１）の継手用筒状部１２に嵌入されている。 The piping member 2 has a configuration in which an auxiliary tube 21 is attached to the tip of a hose 20 . The auxiliary pipe body 21 is a member to which a sealing O-ring 22 is mounted and an annular recessed groove 23 for locking mounting of the stopper 3 is formed on its outer peripheral surface. The auxiliary tubular body 21 is fixedly connected to the distal end of the hose 20 in a manner that prevents it from slipping off. A means is adopted in which the tip of the hose 20 is brought into pressure contact with the auxiliary tube body 21 by compressing and crimping.
The distal end portion of the auxiliary tubular body 21 of the piping member 2 is fitted into the joint cylindrical portion 12 of the bathtub cleaning nozzle 1 (nozzle receiver 11).

止め具３は、一定幅の帯状金属板に曲げ加工を施して形成されたものであり、図３に示すように、一部（上部）に開口部３０を有する正面視二股状の部材である。この止め具３は、その上下高さ方向略中央部が横幅方向両側に突出した正面視略く字状の一対の突出部３１を有している。図１（ａ），（ｂ）に示すように、この止め具３は、配管部材２の環状凹溝２３に、その一部分が係入するようにして配管部材２の外面部に装着されている。止め具３は、開口部３０の幅を拡縮可能とするバネ性をもつため、開口部３０の幅を広げるように一時的に変形させることにより、配管部材２の周囲を取り囲むように止め具３を装着することが可能である。また、このような止め具３の装着は、図２（ａ）に示すよう
に、配管部材２の先端部を浴槽洗浄用ノズル１の継手用筒状部１２に嵌入させた状態で行なう。第１および第２のストッパ壁部１３ａ，１３ｂの相互間の隙間９は、下部開口状であるため、この部分から止め具３を隙間９に進入させてから配管部材２の外面部に装着することが可能である。 The stopper 3 is formed by bending a belt-shaped metal plate of a certain width, and as shown in FIG. . The stopper 3 has a pair of protruding portions 31 which are generally V-shaped when viewed from the front and protrude to both sides in the lateral width direction at approximately the central portion in the vertical height direction. As shown in FIGS. 1(a) and 1(b), the stopper 3 is mounted on the outer surface of the piping member 2 so that a portion thereof engages with an annular groove 23 of the piping member 2. . Since the stopper 3 has a spring property that allows the width of the opening 30 to be expanded and contracted, the stopper 3 is temporarily deformed so as to widen the width of the opening 30 so as to surround the periphery of the piping member 2 . can be worn. 2(a), the tip of the piping member 2 is fitted into the joint tubular portion 12 of the bathtub cleaning nozzle 1. As shown in FIG. Since the gap 9 between the first and second stopper walls 13a and 13b has a lower opening shape, the stopper 3 is inserted into the gap 9 from this part and then attached to the outer surface of the piping member 2. Is possible.

図１（ｂ），（ｃ）によく表れているように、止め具３の突出部３１は、第１および第２のストッパ壁部１３ａ，１３ｂの相互間の隙間９に配されている。このことにより、止め具３は、継手用筒状部１２の軸長方向に変位することは規制される。図１（ｃ）において、配管部材２に抜け力Ｆが作用した場合には、突出部３１が第２のストッパ壁部１３ｂに当接するため、配管部材２が継手用筒状部１２から抜け外れることは適切に防止される。 As shown in FIGS. 1(b) and 1(c), the protrusion 31 of the stopper 3 is arranged in the gap 9 between the first and second stopper walls 13a and 13b. As a result, the stopper 3 is restricted from being displaced in the axial direction of the joint tubular portion 12 . In FIG. 1(c), when a pulling force F acts on the piping member 2, the projecting portion 31 comes into contact with the second stopper wall portion 13b, so that the piping member 2 is pulled out of the joint cylindrical portion 12. is properly prevented.

図１（ｂ）によく表れているように、止め具３の突出部３１は、第３のストッパ壁部１３ｃに対して上下縦幅方向において対向しており、止め具３が矢印Ｎａで示すように、配管部材２の外周面周りに回転した際には、突出部３１が第３のストッパ壁部１３ｃに当接するように構成されている。このことにより、止め具３がそれ以上回転することは適切に阻止される。
第１および第２のストッパ壁部１３ａ，１３ｂの縦幅Ｌａ、および止め具３の縦幅Ｌｂは、継手用筒状部１２の外径Ｌｃ（縦幅）以下の寸法とされており、第１および第２のストッパ壁部１３ａ，１３ｂおよび止め具３は、継手用筒状部１２よりも上方または下方にはみ出した格好にはなっていない。 As shown in FIG. 1(b), the projecting portion 31 of the stopper 3 faces the third stopper wall portion 13c in the vertical width direction, and the stopper 3 is indicated by an arrow Na. Thus, when the piping member 2 rotates around the outer peripheral surface, the protruding portion 31 abuts against the third stopper wall portion 13c. This adequately prevents further rotation of the stop 3 .
The vertical width La of the first and second stopper wall portions 13a and 13b and the vertical width Lb of the stopper 3 are set to be equal to or less than the outer diameter Lc (vertical width) of the joint cylindrical portion 12. The first and second stopper walls 13a, 13b and the stopper 3 do not protrude above or below the joint cylindrical portion 12. As shown in FIG.

次に、前記した流体器具配管接続構造Ａの作用について説明する。 Next, the operation of the fluid device pipe connection structure A described above will be described.

まず、図１（ｃ）を参照して説明したように、配管部材２に装着された止め具３の突出部３１が、第１および第２のストッパ壁部１３ａ，１３ｂの相互間に位置している構成により、配管部材２が継手用筒状部１２の軸長方向に不当に変位することは防止され、抜け止めなどが的確に図られた状態で配管部材２を浴槽洗浄用ノズル１に接続することが可能である。 First, as described with reference to FIG. 1(c), the protrusion 31 of the stopper 3 attached to the piping member 2 is positioned between the first and second stopper walls 13a and 13b. This configuration prevents the piping member 2 from being unduly displaced in the axial direction of the joint tubular portion 12, and the piping member 2 is inserted into the bathtub cleaning nozzle 1 in a state in which the removal of the piping member 2 is properly achieved. It is possible to connect.

第１および第２のストッパ壁部１３ａ，１３ｂは、横幅方向には嵩張っているものの、縦幅方向には嵩張っておらず、また止め具３も縦幅方向には嵩張っていない。本実施形態では、既述したように、それらの縦幅Ｌａ，Ｌｂは、継手用筒状部１２の外径Ｌｃ以下とされている。このため、配管部材２と浴槽洗浄用ノズル１との接続部の薄型化を徹底して図ることが可能である。図１（ａ）に示すように、配管部材２と浴槽洗浄用ノズル１との接続部は、浴槽の底壁部８とその下方に位置する浴室床面７との相互間の狭小スペースに配置されるが、このような狭小スペースに適切に配置することが可能である。なお、配管部材２と浴槽洗浄用ノズル１との接続部の横幅は、比較的大きくなるが、前記した浴槽の底壁部８と浴室床面７との相互間は、横幅方向にはかなり広さをもつため、前記接続部の横幅が大きいことは支障にはならない。 Although the first and second stopper walls 13a and 13b are bulky in the width direction, they are not bulky in the lengthwise direction, and the stopper 3 is also not bulky in the lengthwise direction. In the present embodiment, as described above, the vertical widths La and Lb are set to be equal to or less than the outer diameter Lc of the joint tubular portion 12 . Therefore, it is possible to thoroughly reduce the thickness of the connecting portion between the piping member 2 and the bathtub cleaning nozzle 1 . As shown in FIG. 1(a), the connecting portion between the piping member 2 and the bathtub cleaning nozzle 1 is arranged in a narrow space between the bottom wall portion 8 of the bathtub and the bathroom floor surface 7 positioned below. However, it is possible to place them appropriately in such a small space. Although the width of the connecting portion between the piping member 2 and the bathtub cleaning nozzle 1 is relatively large, the distance between the bottom wall portion 8 of the bathtub and the bathroom floor surface 7 is considerably wide in the width direction. Therefore, the large width of the connecting portion does not pose a problem.

図１（ｂ）を参照して説明したように、止め具３が一定以上の大きな角度で矢印Ｎａ方向に回転することは第３のストッパ壁部１３ｃによって阻止される。止め具３が大きな角度で回転すると、突出部３１が第１および第２のストッパ壁部１３ａ，１３ｂの相互間の隙間９から脱出し、抜け止めなどが図られなくなる虞があるが、本実施形態によれば、そのような虞も適切に解消することが可能である。 As described with reference to FIG. 1(b), the third stopper wall portion 13c prevents the stopper 3 from rotating in the direction of the arrow Na over a certain angle. If the stopper 3 rotates at a large angle, the projecting portion 31 may escape from the gap 9 between the first and second stopper wall portions 13a and 13b, making it impossible to prevent the stopper from slipping out. According to the form, it is possible to appropriately eliminate such concerns.

本発明は、上述した実施形態の内容に限定されない。本発明に係る流体器具配管接続構造の各部の具体的な構成は、本発明の意図する範囲内において種々に設計変更自在である。 The invention is not limited to the content of the embodiments described above. The specific configuration of each part of the fluid device piping connection structure according to the present invention can be changed in various ways within the intended scope of the present invention.

本発明でいう流体器具は、浴槽洗浄用ノズルに限定されず、これ以外の流体器具とすることが可能である。また、配管部材の具体的な種類や構成も限定されない。
