従来、栓蓋を遠隔操作し、排水口を開閉させるための操作装置として、押しボタン式のものが知られている。このような操作装置としては、所定の槽体（例えば、浴槽や洗面台など）やその近傍の構造物である取付対象物に設けられた操作ボタンと、操作ボタンを往復移動可能な状態で支持する支持軸を有してなる操作機構と、操作ボタンが内周側に配置され、取付対象物に直接又は間接的に固定される被固定部材と、操作機構を保持するとともに、被固定部材に接続される継手機構とを備えたものが提案されている（例えば、特許文献１等参照）。 2. Description of the Related Art Conventionally, a push button type is known as an operation device for remotely operating a plug lid and opening and closing a drain outlet. As such an operation device, an operation button provided on a predetermined tank body (for example, a bathtub, a washbasin, etc.) or an object to be attached which is a structure in the vicinity thereof, and the operation button are supported in a reciprocable state. An operation mechanism having a supporting shaft, an operation button disposed on the inner peripheral side, a fixed member that is directly or indirectly fixed to an object to be attached, an operation mechanism that holds the operation mechanism, and a fixed member The thing provided with the coupling mechanism connected is proposed (for example, refer patent document 1 etc.).

また、被固定部材に継手機構を接続する手法としては、継手機構の外周に、周方向に沿った一部に開口部を有する環状（いわゆるＣ字状）のリング部材を設け、継手機構の内周から突出するリング部材の内周部を被固定部材の外周に係止することにより、被固定部材に継手機構を接続する手法が考えられる。 Further, as a method of connecting the joint mechanism to the fixed member, an annular (so-called C-shaped) ring member having an opening in a part along the circumferential direction is provided on the outer periphery of the joint mechanism. A method of connecting the joint mechanism to the fixed member by locking the inner peripheral portion of the ring member protruding from the periphery to the outer periphery of the fixed member is conceivable.

ところで、リング部材は、自身の開口部を拡幅させた状態で、前記開口部に継手機構を通すことにより、継手機構の外周に設けられる。しかしながら、リング部材は、上述の通り、Ｃ字状をなすため、リング部材の環状中心を通るリング部材の中心軸に沿った方向を上下方向としたとき、上方側から見たときであっても、下方側から見たときであっても、リング部材の形状に大きな違いはない。従って、リング部材を継手機構に取付ける際に、誤ってリング部材を上下反対とした状態で、継手機構へと取付けようとしてしまうことが生じやすく、取付作業性の低下を招いてしまいやすい。 By the way, a ring member is provided in the outer periphery of a joint mechanism by letting a joint mechanism pass through the said opening part in the state which expanded its own opening part. However, since the ring member has a C-shape as described above, even when viewed from above when the direction along the center axis of the ring member passing through the annular center of the ring member is the vertical direction. Even when viewed from the lower side, there is no significant difference in the shape of the ring member. Therefore, when attaching the ring member to the joint mechanism, it tends to occur that the ring member is mistakenly turned upside down and tends to be attached to the joint mechanism, and the attachment workability is likely to be lowered.

本発明は、上記事情を鑑みてなされたものであり、その目的は、リング部材を上下左右対称とすることで、リング部材を継手機構に対して正常に取付けられないといった事態をより確実に防止することができ、取付作業性を向上させることができる操作装置を提供することにある。 The present invention has been made in view of the above circumstances, and its purpose is to more reliably prevent the ring member from being normally attached to the joint mechanism by making the ring member vertically and horizontally symmetrical. Therefore, an object of the present invention is to provide an operating device that can improve the mounting workability.

以下、上記目的を解決するのに適した各手段につき、項分けして説明する。なお、必要に応じて対応する手段に特有の作用効果を付記する。 In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

上記手段１によれば、リング部材は、上下左右対称の形状とされており、上下左右の区別がない形状とされている。従って、リング部材を継手機構に対してより確実に正常な状態で取付けることができる。その結果、取付作業性の向上を図ることができる。 According to the said means 1, the ring member is made into the shape which is symmetrical in the up-down and left-right direction, and has the shape which does not distinguish between up-down and left-right. Therefore, the ring member can be more reliably attached to the joint mechanism in a normal state. As a result, it is possible to improve the mounting workability.

加えて、上記手段１によれば、継手機構の外周に係止されるリング部材の内周部が、左右対称に設けられることとなる。従って、継手機構に対するリング部材の係止状態を安定化させることができ、被固定部材に対して継手機構をより強固に、かつ、より安定的に接続することができる。
また、上記手段１によれば、隙間に工具や指を差し込み、取外用突起部に対して継手機構から離間する側に力を加えることで、継手機構からリング部材を比較的容易に取外すことができる。従って、メンテナンス時などにおいて、被固定部材からの継手機構の取外しを非常に容易に行うことができる。 In addition, according to the said means 1, the inner peripheral part of the ring member latched by the outer periphery of a joint mechanism will be provided left-right symmetrically. Therefore, the locked state of the ring member with respect to the joint mechanism can be stabilized, and the joint mechanism can be more firmly and more stably connected to the fixed member.
Further, according to the above means 1, the ring member can be removed from the joint mechanism relatively easily by inserting a tool or a finger into the gap and applying a force to the side of the removal projection part away from the joint mechanism. it can. Therefore, it is possible to very easily remove the joint mechanism from the fixed member during maintenance.

手段２．前記リング部材は、前記開口部を拡幅させた状態で前記開口部に前記継手機構を通すことにより、前記溝部に配置可能に構成され、
前記リング部材を前記溝部に設けた状態において、前記リング部材の外周面は、前記第１突条部の外周面、及び、前記第２突条部の外周面に対して面一とされることを特徴とする手段１に記載の操作装置。 Means 2 . Before Symbol ring member, by passing the joint mechanism in the opening while being widened the opening, it is placeable configured before Kimizo unit,
In a state where the ring member is provided in the groove portion, the outer peripheral surface of the ring member is flush with the outer peripheral surface of the first ridge portion and the outer peripheral surface of the second ridge portion. The operating device according to claim 1, characterized by:

尚、「面一」とあるのは、リング部材の外周面が、第１突状部の外周面及び第２突状部の外周面に対して厳密に面一となっている場合のみならず、リング部材の外周面と第１突状部等の外周面との間に若干（例えば、径方向に沿ったリング部材の外周面と第１突状部等の外周面との間に沿った距離が０．５ｍｍ以下）の段差が形成されている場合も含む。 Note that “the same surface” is not only the case where the outer peripheral surface of the ring member is strictly flush with the outer peripheral surface of the first projecting portion and the outer peripheral surface of the second projecting portion. A little between the outer peripheral surface of the ring member and the outer peripheral surface of the first projecting portion (for example, between the outer peripheral surface of the ring member along the radial direction and the outer peripheral surface of the first projecting portion, etc. This includes the case where a step with a distance of 0.5 mm or less is formed.

上記手段２によれば、リング部材を溝部に設けた状態において、リング部材の外周面が、第１突条部の外周面及び第２突条部の外周面に対して面一となるように構成されている。従って、リング部材に対して工具等が引っ掛かってしまい、リング部材が誤って外れてしまうといった事態をより確実に防止することができる。また、溝部に対するリング部材の配置状態が正常でない場合には、リング部材の外周面と第１突状部等の外周面との間に段差が形成されるため、溝部に対してリング部材が正常に配置されていないことを容易に認識することができる。従って、継手機構に対してリング部材が誤った状態で取付けられてしまうことをより一層確実に防止できる。 According to the above means 2, in a state where the ring member is provided in the groove portion, the outer peripheral surface of the ring member is flush with the outer peripheral surface of the first ridge portion and the outer peripheral surface of the second ridge portion. It is configured. Therefore, it is possible to more reliably prevent a situation in which a tool or the like is caught on the ring member and the ring member is accidentally detached. In addition, when the arrangement state of the ring member with respect to the groove portion is not normal, a step is formed between the outer peripheral surface of the ring member and the outer peripheral surface of the first projecting portion or the like, so the ring member is normal with respect to the groove portion. Can be easily recognized. Therefore, it is possible to more reliably prevent the ring member from being attached to the joint mechanism in a wrong state.

手段３．前記リング部材は、その内周面及びその外周面の間に、上下方向において対称な第１端面及び第２端面を有し、
前記第１端面のうち前記継手機構の内周から突出する部位には、内周側に向けて前記第２端面側に傾斜する第１テーパ部が形成され、
前記第２端面のうち前記継手機構の内周から突出する部位には、内周側に向けて前記第１端面側に傾斜する第２テーパ部が形成されることを特徴とする手段１又は２に記載の操作装置。 Means 3. The ring member has a first end surface and a second end surface symmetrical between the inner peripheral surface and the outer peripheral surface in the vertical direction,
A portion of the first end surface that protrudes from the inner periphery of the joint mechanism is formed with a first taper that is inclined toward the second end surface toward the inner periphery.
Means 1 or 2 characterized in that a portion of the second end surface protruding from the inner periphery of the joint mechanism is formed with a second taper portion inclined toward the first end surface toward the inner periphery. The operating device according to 1.

被固定部材に対して継手機構を接続する際の作業性を高めるべく、リング部材のうち、その内周面とその外周面との間に位置する第１端面及び第２端面のうちの一方の面に、内周側に向けて前記両面のうちの他方の面側に傾斜するテーパ部を設けることが考えられる。このようにテーパ部を形成した場合において、被固定部材に継手機構を接続する際には、被固定部材側へと継手機構を移動させ、前記テーパ部を被固定部材に圧接することにより、リング部材の開口部を拡幅させる。その上で、継手機構をさらに移動させ、継手機構の内周に被固定部材を挿入していき、被固定部材のうち比較的小径に形成された部位までリング部材を移動させることで、リング部材が戻り変形し、リング部材の内周部が被固定部材の外周に係止される。従って、被固定部材に継手機構を接続する際に、リング部材の開口部を拡幅するための作業を特段行う必要はなく、被固定部材に継手機構をワンタッチで接続することができ、取付作業性を高めることができる。 In order to improve workability when connecting the joint mechanism to the member to be fixed, one of the first end surface and the second end surface located between the inner peripheral surface and the outer peripheral surface of the ring member. It is conceivable to provide a tapered portion inclined on the other surface side of the both surfaces toward the inner peripheral side. In the case where the tapered portion is formed in this way, when the joint mechanism is connected to the fixed member, the joint mechanism is moved toward the fixed member side, and the taper portion is pressed against the fixed member, so that the ring The opening of the member is widened. Then, the joint mechanism is further moved, the fixed member is inserted into the inner periphery of the joint mechanism, and the ring member is moved to a portion of the fixed member that is formed to have a relatively small diameter. Is deformed and the inner periphery of the ring member is locked to the outer periphery of the fixed member. Therefore, when connecting the joint mechanism to the member to be fixed, there is no need to perform a special operation for widening the opening of the ring member, and the joint mechanism can be connected to the member to be fixed with a single touch. Can be increased.

しかしながら、リング部材の第１端面及び第２端面のうちの一方の面のみにテーパ部が形成されている場合において、リング部材を上下反対の状態としてしまうと、仮に継手機構にリング部材を取付けることができたとしても、被固定部材に対して継手機構を接続する際に、テーパ部は被固定部材に対して接触しなくなってしまう。そのため、テーパ部を設けることによる取付作業性の向上という作用効果が何ら奏されなくなってしまう。 However, when the tapered portion is formed on only one of the first end surface and the second end surface of the ring member, if the ring member is turned upside down, the ring member is temporarily attached to the joint mechanism. Even if it is possible, when the joint mechanism is connected to the fixed member, the tapered portion does not come into contact with the fixed member. Therefore, the effect of improving the mounting workability by providing the tapered portion is not achieved at all.

この点、上記手段３によれば、リング部材の第１端面及び第２端面の双方に上下対称に形成された第１テーパ部及び第２テーパ部が設けられている。従って、被固定部材に継手機構を接続する際において、リング部材の上下方向における配置向きに関わりなく、上述したテーパ部を設けることによる取付作業性の向上効果を確実に発揮させることができる。 In this regard, according to the means 3, the first taper portion and the second taper portion formed symmetrically in the vertical direction are provided on both the first end surface and the second end surface of the ring member. Therefore, when connecting the joint mechanism to the member to be fixed, regardless of the arrangement direction of the ring member in the vertical direction, the effect of improving the mounting workability by providing the above-described tapered portion can be surely exhibited.

Water that has entered the joint mechanism 7 passes through the pipe 107 and the pipe body 108. It is designed to drain to the side.

次いで、リング部材８の構成について詳述する。リング部材８は、図６（ａ），（ｂ）及び図９に示すように、リング部材８の環状中心を通るリング部材８の中心軸Ｌ１に沿った方向を上下方向とし、前記中心軸Ｌ１に直交する直線Ｌ２に沿った方向を左右方向としたとき、上下左右対称の形状とされている。加えて、リング部材８は、その内周面及びその外周面の間に、上下方向において対称な第１端面８３と第２端面８４とを有している。また、前記溝部７６にリング部材８を配置した際において第１端面８３のうち継手機構７の内周から突出する部位には、内周側に向けて第２端面８４側に傾斜する第１テーパ部８５が設けられている。加えて、前記溝部７６にリング部材８を配置した際において第２端面８４のうち継手機構７の内周から突出する部位には、内周側に向けて第１端面８３側に傾斜する第２テーパ部８６が設けられている。 Next, the configuration of the ring member 8 will be described in detail. As shown in FIGS. 6A, 6B and 9, the ring member 8 has a direction along the center axis L1 of the ring member 8 passing through the annular center of the ring member 8 as the vertical direction, and the center axis L1. When the direction along the straight line L2 orthogonal to is the left-right direction, the shape is symmetrical in the vertical and horizontal directions. In addition, the ring member 8 has a first end surface 83 and a second end surface 84 that are symmetrical in the vertical direction between the inner peripheral surface and the outer peripheral surface. Further, when the ring member 8 is disposed in the groove portion 76, a portion of the first end surface 83 that protrudes from the inner periphery of the joint mechanism 7 is a first taper that is inclined toward the second end surface 84 toward the inner periphery. A portion 85 is provided. In addition, when the ring member 8 is disposed in the groove portion 76, the second end surface 84 protrudes from the inner periphery of the joint mechanism 7 to the second end surface 84 inclined toward the first end surface 83 toward the inner periphery. A tapered portion 86 is provided.

尚、筒状部材３に対して継手機構７を接続する際には、溝部７６にリング部材８を予め配置した上で、筒状部材３の他端側（下方側）において、継手機構７を一端側（上方側）に向けて移動させることで、両テーパ部８５，８６のうち一端側（上方側）に位置する方を、筒状部材３の前記拡径部３３に接触させる。そして、継手機構７をさらに一端側（上方側）へと移動させることで、開口部８１が徐々に拡幅され、リング部材８が徐々に拡径される。リング部材８を拡径させた状態で、リング部材８の内周に被係止部３２が配置されるまで継手機構７を一端側（上方側）へと移動させると、リング部材８が戻り変形し、リング部材８の内周部８２が筒状部材３の被係止部３２に係止される（継手機構７が筒状部材３に接続される）。すなわち、継手機構７は、筒状部材３に対してワンタッチで接続可能となっている。 When connecting the joint mechanism 7 to the tubular member 3, the ring member 8 is previously disposed in the groove 76, and the joint mechanism 7 is connected to the other end side (lower side) of the tubular member 3. By moving toward one end side (upper side), the one located on one end side (upper side) of both the taper portions 85 and 86 is brought into contact with the enlarged-diameter portion 33 of the cylindrical member 3. Then, by moving the joint mechanism 7 further to one end side (upper side), the opening 81 is gradually widened, and the ring member 8 is gradually expanded in diameter. If the joint mechanism 7 is moved to one end side (upward side) until the locked portion 32 is disposed on the inner periphery of the ring member 8 with the ring member 8 having an enlarged diameter, the ring member 8 returns and deforms. Then, the inner peripheral portion 82 of the ring member 8 is locked to the locked portion 32 of the cylindrical member 3 (the joint mechanism 7 is connected to the cylindrical member 3). That is, the joint mechanism 7 can be connected to the tubular member 3 with one touch.

さらに、本実施形態では、筒状部材３（被係止部３２）に係止されるリング部材８２の内周部８２は、左右対称に設けられており、リング部材８２の複数箇所が筒状部材３（被係止部３２）に対して係止されるようになっている。 Furthermore, in this embodiment, the inner peripheral part 82 of the ring member 82 latched by the cylindrical member 3 (latched part 32) is provided symmetrically, and a plurality of locations of the ring member 82 are cylindrical. It is locked with respect to the member 3 (locked portion 32).

また、リング部材８は、左右方向における中心部に上下方向に突出する一対の取外用突起部８７，８８を備えている。リング部材８を溝部７６に配置する際には、継手機構７の中心軸を挟んで対称に設けられた一対の突起からなる規制部７１Ａ，７１Ｂ（図７及び図８等参照）の一方に対して、取外用突起部８７，８８の一方が嵌め込まれる。 Further, the ring member 8 includes a pair of removal projections 87 and 88 protruding in the vertical direction at the center in the left-right direction. When the ring member 8 is disposed in the groove portion 76, it is against one of the restricting portions 71A and 71B (see FIGS. 7 and 8, etc.) composed of a pair of protrusions provided symmetrically across the central axis of the joint mechanism 7. Then, one of the removal projections 87 and 88 is fitted.

加えて、図８に示すように、リング部材８を溝部７６に配置した状態において、取外用突起部８７，８８のうち継手機構７の他端側（下方側）に配置された取外用突起部８８の内周面と、継手機構７の外周面との間には、継手機構７の他端側（下方側）に開口する隙間９１が形成されている。メンテナンス時などにおいて筒状部材３から継手機構７を取外す際には、隙間９１に工具や指等を差し込み、溝部７６へと配置する際の方向とは反対側に向けてリング部材８に力を加えることで、継手機構７からリング部材８を取外すことができ、ひいては筒状部材３から継手機構７を取外すことができる。尚、本実施形態では、隙間９１の幅（取外用突起部８８の内周面と、継手機構７の外周面との間の距離）が所定値以上（例えば、２ｍｍ以上）とされており、工具や指等を隙間９１に対して比較的容易に差し込むことができるようになっている。 In addition, as shown in FIG. 8, in the state where the ring member 8 is disposed in the groove portion 76, the removal projection portion disposed on the other end side (lower side) of the joint mechanism 7 among the removal projection portions 87 and 88. A gap 91 that opens to the other end side (lower side) of the joint mechanism 7 is formed between the inner peripheral surface of 88 and the outer peripheral surface of the joint mechanism 7. When removing the joint mechanism 7 from the tubular member 3 during maintenance or the like, insert a tool or a finger into the gap 91 and apply a force to the ring member 8 in the direction opposite to the direction in which it is placed in the groove 76. In addition, the ring member 8 can be removed from the joint mechanism 7, and as a result, the joint mechanism 7 can be detached from the tubular member 3. In the present embodiment, the width of the gap 91 (the distance between the inner peripheral surface of the removal projection 88 and the outer peripheral surface of the joint mechanism 7) is a predetermined value or more (for example, 2 mm or more), A tool, a finger, or the like can be inserted into the gap 91 relatively easily.

さらに、図３及び図４等に示すように、リング部材８を溝部７６に配置した状態において、リング部材８の外周面は、第１突条部７４の外周面、及び、第２突条部７５の外周面に対して面一となるように構成されており、リング部材８の外周面が継手機構７の外周面から出没しないように構成されている。 Further, as shown in FIGS. 3 and 4 and the like, in the state where the ring member 8 is disposed in the groove 76, the outer peripheral surface of the ring member 8 is the outer peripheral surface of the first protrusion 74 and the second protrusion. The outer peripheral surface of 75 is configured to be flush with the outer peripheral surface of the ring member 8 so that the outer peripheral surface of the ring member 8 does not protrude from the outer peripheral surface of the joint mechanism 7.

以上詳述したように、本実施形態によれば、リング部材８は、上下左右対称の形状とされており、上下左右の区別がない形状とされている。従って、リング部材８を継手機構７に対してより確実に正常な状態で取付けることができる。その結果、取付作業性の向上を図ることができる。 As described in detail above, according to the present embodiment, the ring member 8 has a vertically and horizontally symmetrical shape, and has a shape that does not distinguish between vertically and horizontally. Therefore, the ring member 8 can be more reliably attached to the joint mechanism 7 in a normal state. As a result, it is possible to improve the mounting workability.

また、リング部材８を溝部７６に設けた状態において、リング部材８の外周面が、第１突条部７４の外周面及び第２突条部７５の外周面に対して面一となるように構成されている。従って、リング部材８に対して工具等が引っ掛かってしまい、リング部材８が誤って外れてしまうといった事態をより確実に防止することができる。さらに、溝部７６に対するリング部材８の配置状態が正常でない場合には、リング部材８の外周面と第１突状部７４等の外周面との間に段差が形成されるため、溝部７６に対してリング部材８が正常に配置されていないことを容易に認識することができる。従って、継手機構７に対してリング部材８が誤った状態で取付けられてしまうことをより一層確実に防止できる。 Further, in a state where the ring member 8 is provided in the groove portion 76, the outer peripheral surface of the ring member 8 is flush with the outer peripheral surface of the first protrusion 74 and the outer periphery of the second protrusion 75. It is configured. Therefore, it is possible to more reliably prevent a situation in which a tool or the like is caught on the ring member 8 and the ring member 8 is accidentally detached. Further, when the arrangement state of the ring member 8 with respect to the groove 76 is not normal, a step is formed between the outer peripheral surface of the ring member 8 and the outer peripheral surface of the first projecting portion 74 and the like. Thus, it can be easily recognized that the ring member 8 is not normally disposed. Therefore, it is possible to more reliably prevent the ring member 8 from being attached to the joint mechanism 7 in a wrong state.

加えて、リング部材８の第１端面８３及び第２端面８４の双方には、上下左右対称に形成された第１テーパ部８５及び第２テーパ部８６が設けられている。従って、筒状部材３に継手機構７を接続する際において、リング部材８の上下方向における配置向きに関わりなく、テーパ部を設けることによる取付作業性の向上効果を確実に発揮させることができる。 In addition, both the first end surface 83 and the second end surface 84 of the ring member 8 are provided with a first taper portion 85 and a second taper portion 86 that are formed vertically and horizontally symmetrical. Therefore, when connecting the joint mechanism 7 to the cylindrical member 3, the effect of improving the mounting workability by providing the tapered portion can be surely exhibited regardless of the arrangement direction of the ring member 8 in the vertical direction.

併せて、本実施形態では、隙間９１に工具や指を差し込み、取外用突起部８８に対して継手機構７から離間する側に力を加えることで、継手機構７からリング部材８を比較的容易に取外すことができる。従って、メンテナンス時などにおいて、筒状部材３からの継手機構７の取外しを非常に容易に行うことができる。 At the same time, in this embodiment, the ring member 8 is relatively easily moved from the joint mechanism 7 by inserting a tool or a finger into the gap 91 and applying a force to the removal projection 88 on the side away from the joint mechanism 7. Can be removed. Therefore, it is possible to very easily remove the joint mechanism 7 from the tubular member 3 during maintenance.

また、継手機構７の外周に係止されるリング部材８の内周部８２が、左右対称に設けられている。従って、継手機構７に対するリング部材８の係止状態を安定化させることができ、筒状部材３に対して継手機構７をより強固に、かつ、より安定的に接続することができる。 Moreover, the inner peripheral part 82 of the ring member 8 latched by the outer periphery of the joint mechanism 7 is provided left-right symmetrically. Therefore, the locked state of the ring member 8 with respect to the joint mechanism 7 can be stabilized, and the joint mechanism 7 can be connected to the tubular member 3 more firmly and more stably.
