Description

本発明は、主に不凍給水栓のように、水道凍結防止のために寒冷地で使用され建物の床下の地中に埋設して使用するバルブを、連結部材を介して室内で遠隔操作する際のハンドル装置に関する。 The present invention remotely controls a valve, such as an anti-freeze water faucet, that is used in a cold district to prevent water freeze and is buried in the ground under the floor of a building, indoors via a connecting member. The present invention relates to a handle device.

この種のハンドル装置には、例えば同一出願人による特許文献１（特開平１１−３３６９３８号公報）のものがあり、その従来の発明の実施例を図１１に示す。
なお、説明上、床Ｆ、木ねじＳ、ケーシング１、軸受２、ロッド継手Ｃ１、角パイプＣ３の部材は断面図で示し、それ以外の部材は外観図で示す。
従来のハンドル装置Ａは、ケーシング１、軸受２、操作部本体３、把手４、軸ピン５、止め輪６、線細工ばね８が主な構成部材であり、操作部である把手４が床Ｆ面とほぼ同じ高さで設置され、この把手４は軸ピン５を中心として操作部本体３と垂直方向に回転自在に連結されている。
前記ケーシング１は、床Ｆ面に複数の木ねじＳにより固定し、さらに操作部本体３は、その下端部に方向自在継手Ｔと、さらにロッド継手Ｃ１と横断面が四角形状の角ロッドＣ２及び前記角ロッドＣ２が挿入される四角中空の角パイプＣ３からなる連結部材Ｃを介して、地中Ｇに弁部（図省略）が配置される不凍給水栓Ｖの操作杆Ｈに連結されている。 As this type of handle device, for example, there is one of Patent Document 1 (Japanese Patent Laid-Open No. 11-336938) filed by the same applicant, and an example of the conventional invention is shown in FIG.
For the sake of explanation, the members of the floor F, the wood screw S, the casing 1, the bearing 2, the rod joint C1, and the square pipe C3 are shown in a sectional view, and the other members are shown in an external view.
In the conventional handle device A, the casing 1, the bearing 2, the operation part main body 3, the handle 4, the shaft pin 5, the retaining ring 6, and the wire work spring 8 are the main constituent members, and the handle 4 as the operation part is the floor F. The handle 4 is installed at almost the same height as the surface, and the handle 4 is connected to the operation unit main body 3 so as to be rotatable in the vertical direction around the shaft pin 5.
The casing 1 is fixed to the floor F with a plurality of wood screws S. Further, the operation unit body 3 has a directional universal joint T at its lower end, a rod joint C1, a square rod C2 having a rectangular cross section, and the It is connected to an operating rod H of an antifreeze water tap V in which a valve portion (not shown) is disposed in the ground G through a connecting member C composed of a square hollow square pipe C3 into which a square rod C2 is inserted. .

このハンドル装置Ａは、不凍給水栓Ｖの遠隔操作時に把手４を屹立させて床Ｆに対して水平方向に回転させると、方向自在継手Ｔ及び連結部材Ｃを介して連結された不凍給水栓Ｖの操作杆Ｈが連動して回転し、不凍給水栓Ｖの弁部を遠隔操作で開栓（通水状態）または閉栓（水抜き状態）にでき、建物の水道配管の冬期の水道凍結事故を防げることを特徴とするものである。
このハンドル装置Ａは、操作時のみ把手４を屹立させる構造なので、装置自体が日常生活の邪魔にならない、見栄えが良い等の効果を有するものである。
また、上記の特許文献１の実施例には軸受２が用いられており、この軸受２はケーシング１の下端中心部にケーシング１と同軸上に嵌合挿入されており、その上に外周円形の操作部本体３の一部が載置されている。
この軸受２は、把手４による回転操作による動力が操作部本体３を介して軸受２にも伝達され、上記操作をスムーズにおこなえる役目を担っている。 In the handle device A, the antifreeze water supply connected through the directional universal joint T and the connecting member C when the handle 4 is raised and rotated in the horizontal direction with respect to the floor F during the remote operation of the antifreeze water tap V. The operation rod H of the stopper V rotates in conjunction with it, and the valve part of the antifreeze water tap V can be remotely opened (water passing state) or closed (water drained state). It is characterized by preventing freezing accidents.
Since the handle device A has a structure in which the handle 4 is raised only at the time of operation, the device itself has effects such as not disturbing daily life and good appearance.
Further, in the embodiment of the above-mentioned Patent Document 1, a bearing 2 is used, and this bearing 2 is fitted and inserted coaxially with the casing 1 at the center of the lower end of the casing 1, and has an outer circular shape on the same. A part of the operation unit main body 3 is placed.
The bearing 2 plays a role of smoothly performing the above operation by transmitting the power by the rotation operation by the handle 4 to the bearing 2 through the operation unit main body 3.

また、特許文献１と同様のハンドル装置として、特許文献２（実公平１−２８１３９号公報）も提案されている。
本技術は、文献の第５図に示すように截頭円板ハンドル１２を回転させて円板部分を床上に出現させ、その円板部分を床に対し水平方向に回すと文献の第８図に示す水抜栓１を通水または水抜きに出来るものである。
さらに特許文献３（実公平５−３７１０４号公報）も同様のハンドル装置であり、文献の第１図に示す中央の押しボタン１７を指先で押圧降下させることで、ハンドル８がハンドル収納ケース１より上方に突出し、そのハンドル８を回転操作させる構造である。
なお、前述の「不凍給水栓」と「水抜栓」は同義であり、開栓操作することで水道配管に水を供給（通水）したり、また気温低下で水道凍結の心配のある時は、閉栓（水抜き）操作をおこなうことで水道配管内の水を管外に排出することが可能なバルブのことを指す。 Patent Document 2 (Japanese Utility Model Publication No. 1-281139) has also been proposed as a handle device similar to Patent Document 1.
In the present technology, as shown in FIG. 5 of the literature, when the truncated disc handle 12 is rotated so that the disc portion appears on the floor, and the disc portion is rotated in the horizontal direction with respect to the floor, FIG. The water draining plug 1 shown in FIG.
Further, Patent Document 3 (Japanese Utility Model Publication No. 5-37104) is a similar handle device, and the handle 8 is moved from the handle storage case 1 by pressing and lowering the central push button 17 shown in FIG. This is a structure that projects upward and rotates the handle 8.
The above-mentioned “antifreeze hydrant” and “water drainer” are synonymous, and when water is supplied to the water pipe by opening the water, or when there is a concern about water freezing due to temperature drop. Indicates a valve capable of discharging water in the water pipe to the outside of the pipe by closing (draining) the water.

しかし、図１１に示す特許文献１の従来のハンドル装置Ａは、軸受２の採用により把手４の回転操作に連動する操作部本体３の回転動をスムーズにおこなえる利点を有するが、本装置の構造上、軸受２に操作部本体３が常時載置つまり接触する構造であるため、例えばハンドル装置Ａの無操作時に、その装置上を人が歩行することにより操作部本体３又は把手４に人の体の一部が接触することで、把手４を屹立させていなくても不用意に操作部本体３が回転し、その操作部本体３に方向自在継手Ｔ及び連結部材Ｃを介して連結された不凍給水栓Ｖの操作杆Ｈも回転することで、不凍給水栓Ｖの弁部が一方から他方の状態へ作動してしまう可能性が考えられる。
つまり、不凍給水栓Ｖが閉栓（水抜き状態）であった状態で前記の状況が起きてしまうと、意図せず閉栓状態（水抜き状態）が解除され、不凍給水栓Ｖ内部の弁部がわずかに開栓側（通水状態）に作動し、水道配管の末端に取り付けられているカランが、水抜き作業のために開栓されたままであれば、少量の水がカランから吐水され続けてしまうことをその建物の使用者が気付かないケースが起こり得る。 However, the conventional handle device A of Patent Document 1 shown in FIG. 11 has an advantage that the operation unit main body 3 can be smoothly rotated in conjunction with the rotation operation of the handle 4 by using the bearing 2. In addition, since the operation unit main body 3 is always placed on the bearing 2, that is, in contact with the bearing 2, for example, when the handle device A is not operated, a person walks on the operation unit main body 3 or the handle 4 so Even if the handle 4 does not stand upright due to a part of the body contacting, the operation unit body 3 is inadvertently rotated, and is connected to the operation unit body 3 via the directional universal joint T and the connection member C. The operation rod H of the antifreeze hydrant V also rotates, so that the valve portion of the antifreeze hydrant V may be operated from one state to the other.
That is, if the above situation occurs with the antifreeze hydrant V closed (drained state), the closed state (drained state) is unintentionally released, and the valve inside the antifreeze hydrant V is released. If the section operates slightly on the plug-open side (water flow state) and the curan attached to the end of the water pipe remains open for draining, a small amount of water is discharged from the curan. There may be cases where the user of the building does not realize that it will continue.

特許文献２のハンドル装置においても、無操作時にシャフト吊り１１及び截頭円板ハンドル１２上を人が歩き装置に接触することで、截頭円板ハンドル１２を床上に出現させていない状態でも不用意にシャフト吊り１１及び截頭円板ハンドル１２が回転してしまい、特許文献２の第８図に示す水抜栓１の弁部が一方から他方の状態へ作動してしまう可能性がある。
特許文献３も同様である。
このようなハンドル装置は、室内の隅近傍の床面に設置されていることが多く、その上方を人が歩いてハンドル装置の操作部分に接触する可能性は極めて低いが、改善点として挙げられる。 Even in the handle device of Patent Document 2, it is not possible even when the wharf disc handle 12 is not made to appear on the floor by a person walking on the shaft suspension 11 and the wharf disc handle 12 without operation. There is a possibility that the shaft suspension 11 and the truncated disc handle 12 rotate in preparation, and the valve portion of the water draining plug 1 shown in FIG. 8 of Patent Document 2 operates from one state to the other.
The same applies to Patent Document 3.
Such a handle device is often installed on the floor near the corner of the room, and it is extremely unlikely that a person will walk above it and touch the operation part of the handle device. .

一方、前記把手が屹立状態である操作時には、前記把手の先端部側面が前記動力伝達部材の上面に接触し、且つ前記操作部本体の第２凹部底面と前記ケーシングの第２収容室底面が非接触となることを特徴とする、
誤作動防止構造を有するバルブのハンドル装置であることを第１の解決手段とする。 In order to solve the above problems, the present invention

（第１解決手段）
本発明によれば、把手が操作部本体の第１凹部及び第２凹部内に収納している状態である無操作時は、動力伝達部材の上面と把手とが非接触、且つ操作部本体の第２凹部底面とケーシングの第２収容室底面が接触する構造を採用したので、ハンドル装置に不用意に接触しても、その動力が動力伝達部材及び軸受には伝わらず、且つ操作部本体の第２凹部底面とケーシングの第２収容室底面とが接触していることで摩擦力が生じ操作部本体が回転することは無く、不凍給水栓が開栓状態になって少量の水が出っ放しになる不慮の事故を防ぐことができる。
また、把手の屹立状態である操作時には、把手の先端部側面が動力伝達部材の上面に接触し、且つ前記操作部本体の第２凹部底面と前記ケーシングの第２収容室底面とが非接触となるので、把手の回転操作力が動力伝達部材を介して軸受に伝わるため、スムーズな回転操作がおこなえる。 (First solving means)
According to the present invention, when there is no operation in which the handle is housed in the first recess and the second recess of the operation unit body, the upper surface of the power transmission member and the handle are not in contact with each other, and Since the bottom surface of the second recess and the bottom surface of the second storage chamber of the casing are in contact with each other, even if the handle device is inadvertently contacted, the power is not transmitted to the power transmission member and the bearing, and The bottom surface of the second recess and the bottom surface of the second storage chamber of the casing are in contact with each other, so that frictional force is not generated and the operation unit body does not rotate, and the antifreeze water faucet is opened and a small amount of water is discharged. It can prevent accidents that are left unattended.
Further, during an operation in which the handle is in an upright state, the side surface of the distal end portion of the handle is in contact with the upper surface of the power transmission member, and the bottom surface of the second recessed portion of the operation portion main body and the bottom surface of the second storage chamber of the casing are not in contact with each other. As a result, the rotational operation force of the handle is transmitted to the bearing via the power transmission member, so that a smooth rotational operation can be performed.

（第２解決手段）
本発明によれば、回転操作体である把手又は把手が連結された操作部本体と、非回転体であるケーシングに、両部材が嵌合する凹凸部を設けることで、ハンドル装置の無操作時には、凸部と凹部が嵌合することで前記回転操作体を操作不能に規制することができるため、ハンドル装置に不用意に接触しても、ハンドル装置に連結されている不凍給水栓が開栓状態になって少量の水が出っ放しになる不慮の事故を防ぐことができる。
また、操作時には、前記凸部と前記凹部の嵌合が解除され、前記回転操作体の操作が可能となる。 (Second solution)
According to the present invention, when the handle device is not operated, the handle as a rotating operation body or the operation unit main body to which the handle is connected and the casing as the non-rotating body are provided with the concavo-convex portions for fitting both members. Since the rotating operation body can be regulated to be inoperable by fitting the convex portion and the concave portion, the antifreeze water tap connected to the handle device can be opened even if the handle device is inadvertently contacted. It is possible to prevent an accident where a small amount of water is discharged due to the plug.
Further, at the time of operation, the fitting between the convex portion and the concave portion is released, and the rotary operation body can be operated.

It is housed so as to be able to rotate while straddling the room.

次に、操作部本体３の詳細について説明する。
操作部本体３は、図３に示すようにその上面に略半円形状の第１凹部３ａを形成し、この第１凹部３ａと隣接する側方には、一部を第２凹部底面３ｅ及び第２凹部側面３ｄで囲繞し、内方に貫通部３ｆを設けた前記第１凹部３ａより深い窪みの第２凹部３ｂを形成し、この第１凹部３ａ及び第２凹部３ｂに跨るように略Ｕ字形状の把手４が、軸ピン５を中心として垂直方向に回転自在に連結された状態で収容されている。
なお、前記第２凹部底面３ｅは、図２に示すようにハンドル装置Ａ１の無操作時、ケーシング１の第２収容室底面１ｅに接触している。
また、前記第２凹部３ｂの貫通部３ｆには、その空間に動力伝達部材７が配置されている。 Next, details of the operation unit main body 3 will be described.

次に図３を用いて、ハンドル装置Ａ１の組立について説明する。
なお、図は省略しているが、操作部本体３の第１凹部３ａの裏面には線細工ばね８が取り付けられている。
最初に、ケーシング１の第１収容室１ｂ内に軸受２を嵌合挿入し、その軸受２と同軸上に動力伝達部材７を軸受２に載置する。
その後、動力伝達部材７の上方から、軸ピン５を用いて把手４が連結されている操作部本体３の円柱部３ｃを、動力伝達部材７の貫通孔７ａ及び軸受２の中空部に挿通し、最終的にケーシング１の貫通孔１ｃに挿通後、止め輪６を円柱部３ｃ下部に設けた溝３ｇに嵌め込んで、各部材がケーシング１に対して離脱不能に連結する。
その後、図１に示すように木ねじＳを用いてハンドル装置Ａ１を床Ｆに固定し、さらに円柱部３ｃの下部に、ピン９を用いて方向自在継手Ｔが連結され、図１１に示すように、方向自在継手Ｔは連結部材Ｃを介して不凍給水栓Ｖと連結される。
本実施例において、前記のようにハンドル装置Ａ１（円柱部３ｃ）と方向自在継手Ｔの接続にピン９を用いているが、例えば方向自在継手Ｔにねじ切削加工した横穴を設け、その穴にボルトを螺着して円柱部３ｃの下部に固定して接続する方法であっても良い。 Next, the assembly of the handle device A1 will be described with reference to FIG.

First, the bearing 2 is fitted and inserted into the first housing chamber 1 b of the casing 1, and the power transmission member 7 is placed on the bearing 2 coaxially with the bearing 2.
Thereafter, from above the power transmission member 7, the column portion 3 c of the operation unit main body 3 to which the handle 4 is connected using the shaft pin 5 is inserted into the through hole 7 a of the power transmission member 7 and the hollow portion of the bearing 2. Finally, after being inserted into the through hole 1c of the casing 1, the retaining ring 6 is fitted into the groove 3g provided in the lower part of the cylindrical portion 3c, so that each member is connected to the casing 1 so as not to be detached.
Thereafter, the handle device A1 is fixed to the floor F using a wood screw S as shown in FIG. 1, and the directional universal joint T is connected to the lower portion of the cylindrical portion 3c using a pin 9, as shown in FIG. The directional universal joint T is connected to the antifreeze water tap V via the connecting member C.
In this embodiment, the pin 9 is used to connect the handle device A1 (cylindrical portion 3c) and the directional universal joint T as described above. For example, a lateral hole threaded in the directional universal joint T is provided, and the hole is provided in the hole. A method may be used in which a bolt is screwed and fixed and connected to the lower portion of the cylindrical portion 3c.

なお、本実施例におけるハンドル装置Ａ１は、図１に示すように、本出願人の特許文献１による従来技術と同様に操作部本体３の裏面に線細工ばね８を装着しているので、把手４の屹立時に操作部本体３の下側から把手４に押圧力を与え、操作中、把手４ががたつかず、軸ピン５を中心軸とした回転のみで第１凹部３ａ及び第２凹部３ｂ内に収納できる効果を有している。 As shown in FIG. 1, the handle device A1 in the present embodiment has a wirework spring 8 mounted on the back surface of the operation unit main body 3 as in the prior art according to Patent Document 1 of the present applicant. When the handle 4 is upright, a pressure is applied to the handle 4 from the lower side of the operation unit main body 3 so that the handle 4 does not rattle during the operation, and only the first recess 3a and the second recess 3b are rotated only with the shaft pin 5 as the central axis. It has the effect of being housed inside.

次にハンドル装置Ａ１の操作時について、図４及び図５を用いて説明する。
図４は操作時におけるハンドル装置Ａ１の断面図であり、なお説明の都合上、操作部本体３の一部、把手４、軸ピン５、動力伝達部材７、線細工ばね８の部材を外観図で示し、それ以外の部材は断面図で示す。
また、図５も同じく操作時におけるハンドル装置Ａ１の断面図を示したもので、図４の軸方向Ｙ−Ｙ線に沿って矢印から見た断面図であり、説明上、線細工ばね８の図は省略し、把手４のみを外観図で示している。
図１の状態から把手４の先端部上面４ａを指で押圧すれば、軸ピン５を中心軸として把手４は床Ｆ面と垂直方向に回転し、把手４は約９０度回転して、その先端部底面４ｂが操作部本体３のストッパー部３ｈ（図３参照）に当たり回転を停止する。
同時に、屹立した把手４の先端部側面４ｃの一部が動力伝達部材７の上面７ｂに接触し、さらに軸受２は第１収容室１ｂに嵌合挿入されているために、軸受２が下方への移動を拘束され、軸受２及び動力伝達部材７は接触した状態でその場に留まったままで、把手４と軸ピン５で連結されている操作部本体３のみが上方に僅かに持ち上がり、同時に、それまで接触していた操作部本体３の第２凹部底面３ｅとケーシング１の第２収容室底面１ｅとが離脱する。 Next, the operation of the handle device A1 will be described with reference to FIGS.
FIG. 4 is a cross-sectional view of the handle device A1 during operation. For convenience of explanation, a part of the operation unit body 3, the handle 4, the shaft pin 5, the power transmission member 7, and the wirework spring 8 are external views. The other members are shown in cross-sectional views.
5 also shows a cross-sectional view of the handle device A1 during operation, and is a cross-sectional view seen from the arrow along the axial direction YY line of FIG. The figure is omitted, and only the handle 4 is shown in an external view.
If the tip end upper surface 4a of the handle 4 is pressed with a finger from the state of FIG. 1, the handle 4 rotates in the direction perpendicular to the floor F surface with the shaft pin 5 as the central axis, and the handle 4 rotates about 90 degrees, The tip bottom surface 4b hits the stopper portion 3h (see FIG. 3) of the operation portion main body 3 and stops rotating.
At the same time, a part of the tip side surface 4c of the upright handle 4 is in contact with the upper surface 7b of the power transmission member 7, and the bearing 2 is fitted and inserted into the first accommodating chamber 1b. , The bearing 2 and the power transmission member 7 remain in contact with each other, and only the operation unit body 3 connected by the handle 4 and the shaft pin 5 is lifted slightly upward, The second recess bottom surface 3e of the operation unit main body 3 and the second storage chamber bottom surface 1e of the casing 1 that have been in contact with each other are separated.

このように、把手４の先端部側面４ｃが動力伝達部材７の上面７ｂに接触している状態なので、軸ピン５により連結されている操作部本体３と把手４の荷重が、動力伝達部材７を介して軸受２の内輪２ａにかかるので、軸受２の働きにより把手４を床Ｆ面に対し水平方向に回転させれば、軸ピン５により連結されている操作部本体３が円柱部３ｃを中心軸として回転し、スムーズにハンドル操作をおこなうことができ、図１１に示すように操作部本体３に方向自在継手Ｔ及び連結部材Ｃを介して連結されている不凍給水栓Ｖの操作杆Ｈも同時に回転し、不凍給水栓Ｖの弁部を遠隔操作することができる。 Thus, since the tip end side surface 4 c of the handle 4 is in contact with the upper surface 7 b of the power transmission member 7, the load of the operation unit main body 3 and the handle 4 connected by the shaft pin 5 is the power transmission member 7. Therefore, when the handle 4 is rotated in the horizontal direction with respect to the floor F surface by the action of the bearing 2, the operation portion main body 3 connected by the shaft pin 5 is connected to the cylindrical portion 3c. The operation shaft of the antifreeze water tap V connected to the operation section main body 3 through the directional universal joint T and the connection member C as shown in FIG. H also rotates at the same time, and the valve portion of the antifreeze hydrant V can be remotely operated.

次にハンドル装置Ａ１の無操作時について、図１及び図２を用いて説明する。
ハンドル装置Ａ１の把手４が図３に示す操作部本体３の第１凹部３ａ及び第２凹部３ｂ内に収納されている状態である無操作時においては、操作部本体３の第２凹部底面３ｅとケーシング１の第２収容室底面１ｅとが接触しているが、動力伝達部材７の上面７ｂと把手４とは非接触の状態である。
そのため、ハンドル装置Ａ１の無操作時に操作部本体３及び把手４上を人が歩き、それらの部材上面に人の体の一部が接触しても、その接触によって操作部本体３及び把手４を動かそうとする力が軸受２までは伝わらない。
上記の力は、操作部本体３の第２凹部底面３ｅを介して接触しているケーシング１の第２収容室底面１ｅのみにかかるが、接触面で生じる部材間の摩擦力がストッパーの役目を果たし、ハンドル装置Ａ１自体が不用意に作動することはない。
そのため、前記接触面の摩擦力が大きくなるように前記ケーシング１と操作部本体３とは、例えば同種金属のように、より部材間の摩擦力が大きくなる材質を選択するのが望ましい。 Next, when the handle device A1 is not operated will be described with reference to FIGS.
When the handle 4 of the handle device A1 is housed in the first recess 3a and the second recess 3b of the operation section main body 3 shown in FIG. 3, the second recess bottom surface 3e of the operation section main body 3 is not operated. And the second storage chamber bottom surface 1e of the casing 1 are in contact with each other, but the upper surface 7b of the power transmission member 7 and the handle 4 are not in contact with each other.
Therefore, even if a person walks on the operation unit main body 3 and the handle 4 when the handle device A1 is not operated and a part of the human body comes into contact with the upper surface of those members, the operation unit main body 3 and the handle 4 are brought about by the contact. The force to move is not transmitted to the bearing 2.
The above-described force is applied only to the second storage chamber bottom surface 1e of the casing 1 that is in contact via the second recess bottom surface 3e of the operation unit body 3, but the frictional force between the members generated on the contact surface serves as a stopper. However, the handle device A1 itself does not operate carelessly.
Therefore, it is desirable to select a material that increases the frictional force between the members, such as the same type of metal, for example, the casing 1 and the operation unit main body 3 so that the frictional force of the contact surface is increased.

また、ハンドル装置Ａ１の無操作時に接触する操作部本体３の第２凹部底面３ｅとケーシング１の第２収容室底面１ｅは、その両方もしくは片方の面を凹凸状にしたり、または第２凹部底面３ｅもしくは第２収容室底面１ｅにゴム材質の薄い板状シートを貼付する方法を用いて両部材間で摩擦力をより大きくさせても良く、要は第２凹部底面３ｅと第２収容室底面１ｅとがハンドル装置Ａ１の無操作時には接触、操作時には非接触となる構造であれば、上記のような本発明の要旨を逸脱しない程度の設計変更は自由である。 Further, the second recessed portion bottom surface 3e of the operation portion main body 3 and the second receiving chamber bottom surface 1e of the casing 1 that are in contact with each other when the handle device A1 is not operated have both or one surface made uneven, or the second recessed portion bottom surface. 3e or a method of sticking a thin sheet of rubber material on the bottom surface 1e of the second storage chamber may be used to increase the frictional force between the two members. In short, the bottom surface of the second recess 3e and the bottom surface of the second storage chamber If the structure is in contact with 1e when the handle device A1 is not operated and is not in contact with the handle device A1, the design can be freely changed without departing from the gist of the present invention as described above.

An embodiment of the handle device A2 of the present invention using the second solving means will be described with reference to FIGS.
FIG. 6 is a cross-sectional view of the handle device A2 during no operation, showing an embodiment of the present invention using the second solving means.
FIG. 7 is a plan external view thereof, and FIG. 8 is an external perspective view of only the operation unit main body 111.
FIG. 9 is a cross-sectional view of the handle device A2 as seen from the arrow along the line ZZ in FIG.
In FIG. 9, for the sake of explanation, the sectional view of the floor F and the wood screw S is omitted.
Reference numeral 111 shown in FIG. 6 is an operation unit main body, 112 is a handle, and 113 is a casing.
As shown in FIG. 8, the operation unit main body 111 is composed of a circular top plate 111a and a columnar part 111b. The circular top plate 111a opens a top window 111c having one end forming a convex window 111g.
The cylindrical portion 111b has a notch 111d having the same width as the skylight 111c.
Furthermore, a groove 111e and a joint connection part 111f are provided at the lower part of the cylindrical part 111b.
The handle 112 is a disc that is slightly larger than a semicircle as shown in FIG. 6, and has one end portion having the same shape as the convex window 111 g provided at one end portion of the skylight 111 c of the operation portion main body 111. It has a convex part 112a. (Fig. 7)
In addition, the handle 112 is rotatably connected by a shaft 114 provided at the upper portion of the cylindrical portion 111b of the operation portion main body 111 at the center thereof.

ケーシング１１３は、図６に示すように中空部１１３ａを有する有底型の円形状ケーシングである。
さらに前記中空部１１３ａの側面内周上端部には、図９に示すようにハンドル装置Ａ２の無操作時、把手１１２の凸部１１２ａと嵌合する凹部１１３ｂを円周上に複数形成している。
またケーシング１１３の底部には、図６に示すように操作部本体１１１の円柱部１１１ｂが挿通される貫通孔１１３ｃを有する。 The casing 113 is a bottomed circular casing having a hollow portion 113a as shown in FIG.
Further, as shown in FIG. 9, a plurality of concave portions 113b that fit into the convex portions 112a of the handle 112 are formed on the circumferential upper end portion of the side surface of the hollow portion 113a when the handle device A2 is not operated. .
Further, as shown in FIG. 6, the bottom portion of the casing 113 has a through hole 113 c through which the cylindrical portion 111 b of the operation portion main body 111 is inserted.

次に、図６を用いてハンドル装置Ａ２の組立について説明すると、把手１１２を軸１１４により連結させた操作部本体１１１を、ケーシング１１３の中空部１１３ａ上方から挿入する。
挿入すると最終的に円柱部１１１ｂの下部に設けた溝１１１ｅおよびジョイント接続部１１１ｆ部分が、ケーシング１１３の底部に設けた貫通孔１１３ｃに挿通される。
挿通後、溝１１１ｅに抜け止めリング１１５を嵌め込んで組立が終了となる。
なおジョイント接続部１１１ｆは、図示しないが特許文献２（実公平１−２８１３９号公報）の第８図に示すようなジョイント２６、ロッド２７、ジョイント２８等を介して水抜栓１に連結される。 Next, the assembly of the handle device A2 will be described with reference to FIG. 6. The operation portion main body 111 with the handle 112 connected by the shaft 114 is inserted from above the hollow portion 113 a of the casing 113.
When inserted, the groove 111e and the joint connection portion 111f provided at the bottom of the cylindrical portion 111b are finally inserted into the through hole 113c provided at the bottom of the casing 113.
After the insertion, the retaining ring 115 is fitted into the groove 111e to complete the assembly.
In addition, although not shown in figure, the joint connection part 111f is connected with the drain plug 1 through the joint 26, the rod 27, the joint 28, etc. which are shown in FIG. 8 of patent document 2 (Japanese Utility Model Publication No. 1-281139).

次に第２解決手段におけるハンドル装置Ａ２の操作時について、図１０を用いて説明する。
図１０は、操作時におけるハンドル装置Ａ２の断面図である。
図６の無操作時の状態からハンドル装置Ａ２を用いて水抜栓を遠隔操作したい場合は、図６に示す把手１１２の右端を上から押圧すると、把手１１２は床Ｆに対し垂直方向、詳細には図６の紙面上、時計方向に回転することで図１０の状態になり、凸部１１２ａの上面が操作部本体１１１の円形天板１１１ａ上面の一部に接触して、把手１１２の回転が止まる。
図１０の状態の操作時は、図９に示す把手１１２の凸部１１２ａとケーシング１１３の凹部１１３ｂの嵌合が解除されるので、図１０の状態で把手１１２を床Ｆ面に対し水平方向に回すと、把手１１２と軸１１４を介して連結されている操作部本体１１１が円柱部１１１ｂを中心軸として回転し、特許文献２（実公平１−２８１３９号公報）の第８図に示すようなジョイント２６、ロッド２７、ジョイント２８等を介して水抜栓１の弁部を遠隔操作することができる。
操作後は、把手１１２を、床Ｆに対し前述とは逆の垂直方向に回転させることにより、図６に示すハンドル装置Ａ２の無操作時の状態に戻り、この時、把手１１２の凸部１１２ａが図９に示すケーシング１１３の複数の凹部１１３ｂのいずれかに再び嵌合する。 Next, the operation of the handle device A2 in the second solving means will be described with reference to FIG.
FIG. 10 is a cross-sectional view of the handle device A2 during operation.
6, when it is desired to remotely operate the drain plug using the handle device A2 from the state of no operation, when the right end of the handle 112 shown in FIG. 6 is pressed from above, the handle 112 is perpendicular to the floor F in detail. 6 is rotated in the clockwise direction on the paper surface of FIG. 6 to be in the state of FIG. 10, and the upper surface of the convex portion 112 a comes into contact with a part of the upper surface of the circular top plate 111 a of the operation unit main body 111. Stop.
When the operation in the state of FIG. 10 is performed, the fitting 112a of the handle 112 and the recess 113b of the casing 113 shown in FIG. 9 are disengaged from each other. When it is turned, the operation portion main body 111 connected to the handle 112 via the shaft 114 rotates about the cylindrical portion 111b as a central axis, as shown in FIG. 8 of Patent Document 2 (Japanese Utility Model Publication No. 1-281139). The valve portion of the water drain plug 1 can be remotely operated via the joint 26, the rod 27, the joint 28, and the like.
After the operation, the handle 112 is rotated in the direction perpendicular to the above with respect to the floor F to return to the state in which the handle device A2 shown in FIG. 6 is not operated. At this time, the convex portion 112a of the handle 112 is returned. Is fitted again into any of the plurality of recesses 113b of the casing 113 shown in FIG.

次に第２解決手段におけるハンドル装置Ａ２の無操作時について、図６および図９を用いて説明する。
図９に示すように、無操作時は、把手１１２に設けた凸部１１２ａがケーシング１１３に設けた複数の凹部１１３ｂのいずれかと嵌合している。
この嵌合により、把手１１２が、床Ｆ面に対し水平方向の回転が回転不能に規制されるため、人の体の一部がハンドル装置Ａ２に不用意に接触しても、連結されている水抜栓が遠隔操作されず、少量の水が出っ放しになる不慮の事故を防ぐことができる。 Next, when the handle device A2 is not operated in the second solution means will be described with reference to FIGS.
As shown in FIG. 9, when there is no operation, the convex portion 112 a provided on the handle 112 is fitted to one of the plurality of concave portions 113 b provided on the casing 113.
By this fitting, the handle 112 is restricted from rotating in the horizontal direction with respect to the floor F surface, so that it is connected even if a part of the human body inadvertently contacts the handle device A2. The water stopper is not remotely operated, and it is possible to prevent an unexpected accident in which a small amount of water is discharged.

ちなみに第２解決手段を用いたハンドル装置Ａ２の実施例において、図９に示すケーシング１１３に設けた凹部１１３ｂ間の谷部１１３ｄの幅は、凹部１１３ｂの幅より狭くし、さらに把手１１２の凸部１１２ａやケーシング１１３の凹部１１３ｂの端面部を、テーパーや曲面形状にすることで、操作後に把手１１２を無操作状態に戻す時に、万一把手１１２の凸部１１２ａがケーシング１１３の谷部１１３ｄの位置に重なっても、その谷部１１３ｄの両隣の凹部１１３ｂのいずれかとスムーズに嵌合し易くなる。
そのため、凸部１１２ａが両隣のどちらの凹部１１３ｂに嵌合しても良いように、凹部１１３ｂと次の凹部１１３ｂまでの１ピッチ分の回転では、水抜栓が一方から他方の状態（例えば閉栓から開栓状態）に移行しないように、凹部１１３ｂの数を設定する必要がある。 Incidentally, in the embodiment of the handle device A2 using the second solution means, the width of the valley 113d between the recesses 113b provided in the casing 113 shown in FIG. 9 is made smaller than the width of the recess 113b, and the protrusions of the handle 112 are further made. 112a and the end surface of the recess 113b of the casing 113 are tapered or curved, so that when the handle 112 is returned to the non-operating state after the operation, the convex 112a of the handle 112 should be positioned at the position of the valley 113d of the casing 113. Even if they overlap, it becomes easy to smoothly fit with either of the recesses 113b adjacent to the valley 113d.
Therefore, so that the convex portion 112a can be fitted to either of the concave portions 113b on both sides, the drain plug is turned from one side to the other state (for example, from the plugged state) in the rotation for one pitch from the concave portion 113b to the next concave portion 113b. It is necessary to set the number of recesses 113b so as not to shift to the (opened state).

また、第２解決手段を用いたハンドル装置Ａ２の実施例において、図９に示すように把手１１２側に凸部１１２ａを設けてケーシング１１３側の凹部１１３ｂと嵌合するようにしているが、それとは逆に把手１１２側に凹部、ケーシング１１３側に凸部を設けても良く、要するにハンドル装置の非操作時に凹凸部が嵌合し、操作時にその嵌合が解除される構造であれば良い。 Further, in the embodiment of the handle device A2 using the second solving means, as shown in FIG. 9, a convex portion 112a is provided on the handle 112 side so as to be fitted to the concave portion 113b on the casing 113 side. Conversely, a concave portion may be provided on the handle 112 side and a convex portion may be provided on the casing 113 side. In short, any structure may be used as long as the concave and convex portions are fitted when the handle device is not operated and the fitting is released during operation.

上記の第２解決手段は、特許文献３（実公平５−３７１０４号公報）に採用することも可能であり、図示しないが例えば特許文献３の第１図に示す実施例において、ハンドル８の側面外周に凸部を、ハンドル収納ケース１の中空部の側面内周にハンドル８の前記凸部に嵌合する形状の凹部を設け、無操作時は凸部と凹部が嵌合することでハンドル８の回転を回転不能に規制し、操作時はハンドル８を上方に持ちあげることで凸部と凹部の嵌合が解除され、無操作時のハンドル装置の誤作動を防止することが可能である。 The second solving means described above can be adopted in Patent Document 3 (Japanese Utility Model Publication No. 5-37104). Although not shown, for example, in the embodiment shown in FIG. A convex portion is provided on the outer periphery, and a concave portion having a shape to be fitted to the convex portion of the handle 8 is provided on the inner periphery of the side surface of the hollow portion of the handle storage case 1. The rotation of the handle is restricted to be non-rotatable and the handle 8 is lifted upward at the time of operation, so that the fitting of the convex portion and the concave portion is released, thereby preventing the handle device from malfunctioning when not operated.
