Description

この発明は、洗浄ハンドルの回動操作によってタンク内に貯えた便器の洗浄水を排出させ、便器洗浄を行わせる洗浄ハンドル装置に関する。   The present invention relates to a cleaning handle device for discharging toilet flushing water stored in a tank by rotating the cleaning handle to perform toilet flushing.

タンク内に貯えた便器の洗浄水を、洗浄ハンドルの回動操作により排出し、便器洗浄を行わせる洗浄ハンドル装置の一種として、便器の洗浄水を貯えた内側タンクを包むように設けた外側タンクの壁部(外側壁部)の外面に洗浄ハンドルを回動可能に設ける一方、内側タンク内部を延びるように作用レバーを設けて、その作用レバーに排水弁を連繋し、洗浄ハンドルの回動操作により作用レバーを回動させて排水弁を開弁動作させ、洗浄水を便器に向けて排出させるようになした洗浄ハンドル装置が公知である。   As a kind of washing handle device that drains the toilet flushing water stored in the tank by rotating the washing handle and performs toilet flushing, an outer tank provided to wrap the inner tank that stores the toilet flushing water. A cleaning handle is rotatably provided on the outer surface of the wall (outer wall), while an operating lever is provided so as to extend inside the inner tank, and a drain valve is connected to the operating lever. A cleaning handle device is known in which an operation lever is rotated to open a drain valve so that cleaning water is discharged toward a toilet.

また同種の洗浄ハンドル装置として、キャビネットの内部に内側タンクを収容し、内側タンクの外側に位置するキャビネットの前板(外側壁部)の前面(外面)に洗浄ハンドルを設け、キャビネットの外側でハンドル操作するようになしたものも知られている。   As a cleaning handle device of the same type, the inner tank is housed inside the cabinet, and a cleaning handle is provided on the front (outer surface) of the front plate (outer wall) of the cabinet located outside the inner tank. Some are known to operate.

この種の洗浄ハンドル装置では、従来、洗浄ハンドルに加えられた操作力を作用レバーに伝えるための駆動軸を内側タンクに回動可能に取り付けた上で、これを内側タンク外に延出させて外側壁部に設けた貫通の挿通孔に通し、そして外側壁部の外面において洗浄ハンドルを駆動軸に一体回転状態に固定し連結するようにしていた。
例えば下記特許文献1に、この種の洗浄ハンドル装置の一例が開示されている。
In this type of cleaning handle device, conventionally, a drive shaft for transmitting an operating force applied to the cleaning handle to the operating lever is rotatably attached to the inner tank, and then this is extended outside the inner tank. The cleaning handle is fixedly connected to the drive shaft in an integrally rotated state on the outer surface of the outer wall portion through a through-hole inserted in the outer wall portion.
For example, Patent Document 1 below discloses an example of this type of cleaning handle device.

ところが内側タンクの壁部と外側壁部との間には、通常かなりの間隔があるために、外側壁部の挿通孔の位置と内側タンクから延び出した駆動軸の位置との位置合せを正確に行うことが難しく、特に施工誤差等により駆動軸が内側タンクから斜めに延びていたりすると、挿通孔の位置が駆動軸の位置からずれてしまったりする。   However, since there is usually a considerable gap between the inner tank wall and the outer wall, the alignment between the position of the insertion hole in the outer wall and the position of the drive shaft extending from the inner tank is accurate. If the drive shaft extends obliquely from the inner tank due to construction errors or the like, the position of the insertion hole may deviate from the position of the drive shaft.

そこで例えば後者の洗浄ハンドル装置、即ちキャビネットの内部に内側タンクを収容した形態のものにおいて、キャビネットの前板(外側壁部)に大きな開口を設けて、そこに上記挿通孔を備えた調整金具を取り付け、調整金具の取付位置を調節(変更)することで、挿通孔の位置を駆動軸の位置に位置合せすることが行われていた。   Therefore, for example, in the latter cleaning handle device, that is, in the form in which the inner tank is accommodated in the cabinet, a large opening is provided in the front plate (outer wall portion) of the cabinet, and an adjustment fitting provided with the insertion hole is provided there. The position of the insertion hole is aligned with the position of the drive shaft by adjusting (changing) the mounting position of the mounting and adjusting bracket.

ところが、施工時においてその位置合せが十分に行われないことがあり、この場合、挿通孔を挿通した状態の駆動軸が挿通孔の内面に接触したり引掛ったりしてしまい、そのような状態の下では使用者が洗浄ハンドルを回動操作するときには接触等による抵抗に打ち勝ってこれを回動操作することができたとしても、その後使用者が洗浄ハンドルから手を離したときに洗浄ハンドルが元の位置まで戻らず、排水弁が閉弁し切らないでタンク内の洗浄水が出っ放しになってしまうといった不具合が生ずる。   However, the alignment may not be sufficiently performed at the time of construction. In this case, the drive shaft inserted through the insertion hole comes into contact with or is caught by the inner surface of the insertion hole. If the user rotates the cleaning handle, even if the user can overcome the resistance due to contact, etc. and rotate the cleaning handle, the cleaning handle will remain when the user releases the cleaning handle. There is a problem that the cleaning water in the tank is left without returning to the original position, the drain valve being closed and not being exhausted.

尚本発明に対する先行技術として、下記特許文献2には外側タンクに回動可能に取り付けられる洗浄ハンドル側のハンドル軸(駆動軸)と、内側タンクに回動可能に取り付けられる作用レバー側の作動軸(従動軸)とを分離してハンドル軸に屈曲形状の当接部を、作動軸に同じく屈曲形状をなす被当接部を設け、洗浄ハンドルの回動操作によりそれら当接部と被当接部との当接作用で作用レバーを回動させるようになした点が開示されているが、このものは当接部と被当接部とがそれぞれ何れも単一である点で本発明とは異なっている。   As prior art to the present invention, Patent Document 2 below discloses a handle shaft (drive shaft) on the cleaning handle side that is rotatably attached to the outer tank, and an operating shaft on the action lever side that is rotatably attached to the inner tank. Separated from the (driven shaft), a bent contact portion is provided on the handle shaft, and a contact portion having the same bent shape is provided on the operating shaft. It is disclosed that the operating lever is rotated by the abutting action with the part, but this is different from the present invention in that the abutting part and the abutted part are both single. Is different.

発明の作用・効果Effects and effects of the invention

以上のように本発明は、外側壁部に回動可能に取り付けられる、洗浄ハンドル側の駆動軸と、内側タンクに回動可能に取り付けられる、作用レバー側の従動軸とを分離して設けるとともに、洗浄ハンドル側の駆動軸には軸線周りに駆動軸と一体回動する当接部を、作用レバー側の従動軸には軸線周りに従動軸と一体回動する被当接部をそれぞれ設け、洗浄ハンドルの回動時にそれら当接部と被当接部との当接作用で駆動軸及び従動軸を介し作用レバーを回動させるようになし、且つ当接部と被当接部との少なくとも一方を、対応する駆動軸又は従動軸の軸線周りの複数個所に設けたものである。   As described above, the present invention separates the drive shaft on the cleaning handle side that is rotatably attached to the outer wall portion and the driven shaft on the action lever side that is rotatably attached to the inner tank. The cleaning handle side drive shaft is provided with a contact portion that rotates integrally with the drive shaft around the axis line, and the driven shaft on the action lever side is provided with a contact portion that rotates integrally with the driven shaft around the axis line. When the cleaning handle is rotated, the abutting action between the abutting portion and the abutted portion rotates the operating lever via the drive shaft and the driven shaft, and at least the abutting portion and the abutted portion One is provided at a plurality of locations around the axis of the corresponding drive shaft or driven shaft.

本発明によれば、従来のように内側タンクから延び出した駆動軸を外側壁部の挿通孔に通す必要がないため、挿通孔と駆動軸との面倒な位置合せ作業を不要化でき、施工を簡単化することができる。   According to the present invention, since it is not necessary to pass the drive shaft extending from the inner tank through the insertion hole of the outer wall portion as in the prior art, it is possible to eliminate the troublesome alignment work between the insertion hole and the drive shaft. Can be simplified.

一方で本発明では、施工誤差により洗浄ハンドル側の駆動軸と作用レバー側の従動軸の軸位置がずれていた場合であっても、洗浄ハンドルを回動操作すると、その回動の途中で駆動軸の当接部を従動軸の被当接部に当接させて従動軸を軸線周りに回動させることができ、施工誤差を吸収して洗浄ハンドルに加えられた操作力を確実に作用レバーに伝達し得、内側タンク内の洗浄水の排出即ち便器洗浄を確実に行わせることができる。   On the other hand, in the present invention, even if the shaft position of the drive shaft on the cleaning handle side and the driven shaft on the action lever side is shifted due to a construction error, if the cleaning handle is rotated, it is driven in the middle of the rotation. The abutment part of the shaft can be brought into contact with the abutted part of the driven shaft so that the driven shaft can be rotated around the axis, and the operating force applied to the cleaning handle can be reliably acted upon by absorbing construction errors. It is possible to reliably discharge the washing water in the inner tank, that is, toilet flushing.

また従来のように駆動軸が挿通孔の内面に接触したり引掛ったりして抵抗を生じ、その抵抗により回動操作した洗浄ハンドルが元の位置に戻らない戻り不良の問題を解決でき、確実に洗浄ハンドルを元の位置へと戻すことができる。
これにより、開弁動作した排水弁を確実に閉弁動作させることができ、止水不良による水の出っ放しの問題を解消することができる。
In addition, the drive shaft contacts or gets caught by the inner surface of the insertion hole as before, creating resistance, and the resistance of the cleaning handle that is rotated by the resistance does not return to its original position. The cleaning handle can be returned to its original position.
As a result, the drain valve that has performed the valve opening operation can be reliably closed, and the problem of water discharge due to poor water stoppage can be solved.

本発明は、上記当接部と被当接部との少なくとも一方を、対応する駆動軸又は従動軸の軸線周りの複数個所に設けてあることを特徴としている。
例えば当接部を複数とし、そしてこれを180°隔たった2個所に設けておけば(被当接部を1個所として)、洗浄ハンドルを回動操作したとき、少なくとも180°以内の回動で当接部を被当接部に当接させることができ、引続く洗浄ハンドルの回動操作に基づいて従動軸を回動させ、便器洗浄を行わせることができる。
この点は当接部を1個所とし、被当接部を2個所とした場合においても同様である。
The present invention is characterized in that at least one of the contact portion and the contacted portion is provided at a plurality of locations around the axis of the corresponding drive shaft or driven shaft.
For example, if there are a plurality of contact portions and these are provided at two positions separated by 180 ° (with the contacted portion as one location), when the cleaning handle is rotated, it can be rotated at least within 180 °. The abutting portion can be brought into contact with the abutted portion, and the toilet shaft can be cleaned by rotating the driven shaft based on the subsequent rotation operation of the cleaning handle.
This also applies to the case where the contact portion is one place and the contacted portions are two places.

更に当接部と被当接部との少なくとも一方を3個所以上の複数に設けておけば、洗浄ハンドルを回動操作したときにより少ない回動角度のもとで当接部を被当接部に当接させ得、即ち回動方向において当接部と被当接部との間の隙間、つまり遊びをより少なくし得て、便器洗浄動作の応答性を高めることができる。   Furthermore, if at least one of the contact portion and the contacted portion is provided in a plurality of three or more locations, the contact portion can be moved under a smaller rotation angle when the cleaning handle is rotated. In other words, the clearance between the contact portion and the contacted portion in the rotation direction, that is, play can be further reduced, and the responsiveness of the toilet bowl cleaning operation can be improved.

また請求項5に従って、洗浄ハンドルを一方向に回動操作することで大流量で洗浄水を排出する大洗浄を、他方向に回動操作することで小流量で洗浄水を排出する小洗浄を行うものとなしておいた場合、大洗浄,小洗浄の何れの回動操作の際にも上記効果を得ることができる。
ここで複数個所に設けられる当接部,被当接部については軸線周りに即ち回動方向に等間隔で設けておくことができる。
Further, according to claim 5, large washing for discharging washing water at a large flow rate by rotating the washing handle in one direction, and small washing for discharging washing water at a small flow rate by rotating in another direction. In the case where it is to be performed, the above-described effect can be obtained in both of the large cleaning operation and the small cleaning operation.
Here, the abutting portions and the abutted portions provided at a plurality of locations can be provided at equal intervals around the axis, that is, in the rotation direction.

本発明では、上記当接部と被当接部とのそれぞれを、対応する駆動軸又は従動軸の軸線周りの複数個所に設けておくことができる(請求項2)。
このようにすれば、洗浄ハンドルの回動操作に対する従動軸の回動、特に施工誤差を生じていたときの従動軸の応答性即ち便器洗浄動作の応答性をより一層高めることができる。
In the present invention, each of the abutting portion and the abutted portion can be provided at a plurality of locations around the axis of the corresponding drive shaft or driven shaft.
In this way, the rotation of the driven shaft with respect to the rotation operation of the cleaning handle, in particular, the response of the driven shaft when a construction error occurs, that is, the responsiveness of the toilet bowl cleaning operation can be further enhanced.

また請求項2においても、洗浄ハンドルを一方の回動操作で大洗浄を、他方の回動操作で小洗浄を行うようになしておいた場合、大洗浄時,小洗浄時の何れにおいても洗浄ハンドルの回動操作に対する便器洗浄動作の応答性を高めることができる。
この請求項2において、当接部及び被当接部の何れをも軸線周りに等間隔に設けておくことができる。
Further, in claim 2, when the cleaning handle is designed to perform a large cleaning by one rotation operation and a small cleaning by the other rotation operation, the cleaning handle is cleaned at both the large cleaning time and the small cleaning time. The responsiveness of the toilet bowl cleaning operation to the turning operation of the handle can be enhanced.
In this aspect, both the contact portion and the contacted portion can be provided at equal intervals around the axis.

本発明では、当接部と被当接部との一方を、対応する駆動軸又は従動軸の一方からその軸線と交差する向きに延出した棒状部となし、他方をその棒状部に対して交差する向きに駆動軸又は従動軸の他方から突き出した突出部となしておくことができる。   In the present invention, one of the abutting portion and the abutted portion is formed as a rod-like portion extending from one of the corresponding drive shaft or driven shaft in a direction intersecting with the axis, and the other with respect to the rod-like portion. It can be set as the protrusion part which protruded from the other of the drive shaft or the driven shaft in the crossing direction.

ここで突出部もまた棒状に形成しておくことができる。
また突出部は、作用レバー側の従動軸又は洗浄ハンドル側の駆動軸から軸直角方向に離れた部位で軸方向に突き出した形状となしておくこともできるし、或いは軸から且つ軸線と交差する向きに延出した形状で設けておくこともできる。
Here, the protrusion can also be formed in a rod shape.
Further, the projecting portion may have a shape projecting in the axial direction at a position away from the driven shaft on the action lever side or the drive shaft on the cleaning handle side in the direction perpendicular to the axis, or intersects the axis from the axis. It can also be provided in a shape extending in the direction.

この請求項3においては、請求項2に従って当接部と被当接部とのそれぞれを軸線周りの複数個所に設ける場合において、それら当接部と被当接部とのそれぞれを、軸線周りに90°ごと隔たった4個所に設けておくことが望ましい。   According to the third aspect of the present invention, in the case where the abutting portion and the abutted portion are provided at a plurality of positions around the axis according to the second aspect, the abutting portion and the abutted portion are arranged around the axis. It is desirable to provide them at four points separated by 90 °.

本発明ではまた、洗浄ハンドル側の駆動軸,作用レバー側の従動軸の設置状態において、当接部と被当接部との間の隙間を全体的に若しくは部分的に埋める隙間埋め部材を設けておくことができる(請求項4)。
このようにすれば、洗浄ハンドルの回動方向の遊びを無くし又は少なくし得て、洗浄ハンドルの回動操作に対する便器洗浄動作の応答性をより一層高めることができる。
In the present invention, there is also provided a gap filling member that entirely or partially fills the gap between the contact portion and the contacted portion in the installed state of the drive shaft on the cleaning handle side and the driven shaft on the action lever side. (Claim 4).
In this way, play in the rotation direction of the cleaning handle can be eliminated or reduced, and the responsiveness of the toilet bowl cleaning operation to the rotation operation of the cleaning handle can be further enhanced.

また本発明では、請求項1〜4の何れにおいても洗浄ハンドルを、一方向に回動操作することで大洗浄を、他方向に回動操作することで小洗浄を行うものとなしておくことができる(請求項5)。   According to the present invention, in any one of claims 1 to 4, the cleaning handle is rotated in one direction to perform large cleaning, and the other is rotated in the other direction to perform small cleaning.

These four contact portions 100-1 to 100-4 are positioned between the four contacted portions 76-1 to 76-4 when the drive shaft 78 and the driven shaft 74 are assembled.

詳しくは、例えば図6に示すように当接部100-1が回転方向において被当接部76-1と76-2との間の位置に、また当接部100-2が同じく回転方向において被当接部76-2と76-3との間の位置に、また当接部100-3が被当接部76-3と76-4との間の位置に、更に当接部100-4が被当接部76-4と76-1との間の位置にそれぞれ位置せしめられる。   Specifically, for example, as shown in FIG. 6, the contact portion 100-1 is located at a position between the contacted portions 76-1 and 76-2 in the rotational direction, and the contact portion 100-2 is also in the rotational direction. At the position between the abutted portions 76-2 and 76-3, the abutting portion 100-3 at the position between the abutted portions 76-3 and 76-4, and the abutting portion 100-. 4 is positioned at a position between the contacted portions 76-4 and 76-1.

尚、駆動軸78には図2に示しているように円板状の回動部104が一体回動状態に設けられており、そしてその回動部104の面上に、図中左右一対の係合部106が左右方向に突き出す状態で設けられている。   As shown in FIG. 2, the drive shaft 78 is provided with a disk-shaped rotating portion 104 in an integrally rotating state, and a pair of left and right in the drawing is formed on the surface of the rotating portion 104. The engaging part 106 is provided in a state protruding in the left-right direction.

一方上記の軸受部材80には、図5に示しているように凹部108が設けられていて、凹部108の内部に、引張りコイルスプリングから成る復帰ばね110が収容されている。そしてこの復帰ばね110の両端に、一対の係合部材112が取り付けられている。   On the other hand, the bearing member 80 is provided with a recess 108 as shown in FIG. 5, and a return spring 110 made of a tension coil spring is accommodated in the recess 108. A pair of engagement members 112 are attached to both ends of the return spring 110.

これら係合部材112は、軸方向に突出した係合部114を備えており、それら係合部114が駆動軸78側の上記の係合部106に対し上向きに係合するようになしてある。
尚図5において、116は係合部材112の図中上向き方向の回動端を規定するストッパである。
These engaging members 112 are provided with engaging portions 114 projecting in the axial direction, and these engaging portions 114 are engaged with the engaging portions 106 on the drive shaft 78 side upward. .
In FIG. 5, reference numeral 116 denotes a stopper that defines the pivot end of the engaging member 112 in the upward direction in the figure.

ここで復帰ばね110は、図1に示す洗浄ハンドル32を反時計方向に回動操作して大洗浄を行い、或いは時計方向に回動操作して小洗浄を行ったとき、洗浄ハンドル32から手を離したときに、洗浄ハンドル32を弾性力で自動的にもとの中立位置に復帰させる働きをなす。   Here, when the cleaning handle 32 shown in FIG. 1 is rotated counterclockwise to perform large cleaning, or the clockwise rotation of the cleaning spring 32 shown in FIG. When the button is released, the cleaning handle 32 is automatically returned to the neutral position by an elastic force.

詳しくは、洗浄ハンドル32を図1において反時計方向に回動操作すると、図5(A)中左側の係合部114と駆動軸78側の図2中左側の係合部106との係合作用で、復帰ばね110が引き伸ばされ弾性力を蓄える。
従って洗浄ハンドル32に加えていた操作力を除くと、その復帰ばね110に蓄えられた弾性力によって、洗浄ハンドル32がもとの位置へと復帰せしめられる。
Specifically, when the cleaning handle 32 is turned counterclockwise in FIG. 1, the engagement between the left-hand engagement portion 114 in FIG. 5A and the left-hand engagement portion 106 in FIG. Therefore, the return spring 110 is stretched to store the elastic force.
Accordingly, when the operating force applied to the cleaning handle 32 is removed, the cleaning handle 32 is returned to the original position by the elastic force stored in the return spring 110.

逆に洗浄ハンドル32を時計方向に回動操作したときには、図5中右側の係合部114と、図2中右側の係合部106との係合作用で、係合部材112の回動を伴って復帰ばね110が引き伸ばされ弾性力を蓄える。
そして洗浄ハンドル32に加えていた操作力を除くと、蓄えられた弾性力によって洗浄ハンドル32が元の中立位置へと自動的に戻される。
尚一対の係合部材112の図5中上向きの回動運動は、ストッパ116への当接によって規制される。
Conversely, when the cleaning handle 32 is rotated clockwise, the engaging member 112 is rotated by the engaging action of the engaging portion 114 on the right side in FIG. 5 and the engaging portion 106 on the right side in FIG. Along with this, the return spring 110 is stretched to accumulate elastic force.
When the operating force applied to the cleaning handle 32 is removed, the cleaning handle 32 is automatically returned to the original neutral position by the stored elastic force.
The upward rotation of the pair of engaging members 112 in FIG. 5 is restricted by contact with the stopper 116.

本実施形態では、洗浄ハンドル装置28の組付けに際して、具体的には洗浄ハンドル32側の駆動軸78即ちキャビンネット10における前板16側の駆動軸78、及び作用レバー34側の従動軸74即ち内側タンク24側の従動軸74をそれぞれ組み付けるにあたって、それら駆動軸78,従動軸74の位置(軸直角方向位置、更には軸方向位置)を正確に位置合せする必要はなく、それぞれを単独に前板16,内側タンク24に取り付けるだけでよく、これにより駆動軸78と従動軸74とを連繋して回動運動させることができる。   In the present embodiment, when the cleaning handle device 28 is assembled, specifically, the driving shaft 78 on the cleaning handle 32 side, that is, the driving shaft 78 on the front plate 16 side in the cabin net 10 and the driven shaft 74 on the action lever 34 side. When assembling the driven shafts 74 on the inner tank 24 side, it is not necessary to accurately align the positions of the drive shaft 78 and the driven shaft 74 (the position perpendicular to the axis, and further the position in the axial direction). It is only necessary to attach to the plate 16 and the inner tank 24, whereby the drive shaft 78 and the driven shaft 74 can be linked and rotated.

図6及び図7はその際の作用を表している。
図6は、駆動軸78及び従動軸74が軸直角方向に誤差無く取り付けられたときの状態を表しており、このとき駆動軸78側の4個所の当接部100-1〜100-4は、従動軸74側の4個所の被当接部76-1〜76-4の間の丁度中央に位置した状態となる。
6 and 7 show the operation at that time.
FIG. 6 shows a state where the drive shaft 78 and the driven shaft 74 are attached in the direction perpendicular to the axis without error. At this time, the four contact portions 100-1 to 100-4 on the drive shaft 78 side are shown in FIG. In other words, it is in a state of being located at the center between the four contacted portions 76-1 to 76-4 on the driven shaft 74 side.

詳しくは、例えば当接部100-1が両隣の被当接部76-1と76-2との間の丁度中央に位置し、また当接部100-2が同じく両隣の被当接部76-2と76-3との間の丁度中央に位置し、更に当接部100-3が両隣の被当接部76-3と76-4との丁度中央に位置し、更に当接部100-4が両隣の被当接部76-4と76-1との間の丁度中央に位置した状態となる。   Specifically, for example, the abutting portion 100-1 is positioned just in the center between the adjacent abutted portions 76-1 and 76-2, and the abutting portion 100-2 is also the adjacent abutted portion 76. -2 and 76-3 are located at the center, and the contact part 100-3 is located at the center between the adjacent contact parts 76-3 and 76-4. -4 is in a state located at the center between the contacted portions 76-4 and 76-1 on both sides.

従って、この状態で洗浄ハンドル32を図1において反時計方向に回動操作したとき即ち大洗浄操作したとき、4つの当接部100-1,100-2,100-3,100-4が、図6(B)に示しているようにそれぞれ同時に被当接部76-1,76-2,76-3,76-4に当接し、引続く洗浄ハンドル32の回動操作とともに駆動軸78から従動軸74に回動運動が伝達されて、従動軸74が洗浄ハンドル32と一体的に同じ方向に回動運動する。   Accordingly, when the cleaning handle 32 is rotated counterclockwise in FIG. 1 in this state, that is, when the large cleaning operation is performed, the four contact portions 100-1, 100-2, 100-3, 100-4 are As shown in FIG. 6 (B), they simultaneously abut against the abutted portions 76-1, 76-2, 76-3, and 76-4, and the rotation of the cleaning handle 32 continues from the drive shaft 78. The rotational movement is transmitted to the driven shaft 74, and the driven shaft 74 rotates in the same direction as the cleaning handle 32.

そしてその回動運動が、図3のかさ歯車66,48の噛合いに基づいて作用レバー34に伝えられ、ここにおいて作用レバー34が、図4に示す中立位置から回動運動して内側タンク24底部の排水弁を引張り、これを開弁動作させる。
これにより、内側タンク24内に貯えられていた洗浄水が便器に向けて勢い良く排出され、便器の大洗浄動作が行われる。
Then, the rotational movement is transmitted to the action lever 34 based on the meshing of the bevel gears 66 and 48 in FIG. 3, and the action lever 34 is turned from the neutral position shown in FIG. Pull the drain valve at the bottom and open it.
Thereby, the wash water stored in the inner tank 24 is discharged to the toilet bowl vigorously, and the toilet bowl is largely washed.

一方、洗浄ハンドル32を図1において時計方向に回動操作即ち小洗浄操作したときには、図6(C)に示しているように当接部100-1が被当接部76-2に,当接部100-2が被当接部76-3に、当接部100-3が被当接部76-4に、当接部100-4が被当接部76-1に対してそれぞれ同時に当接し、その後の引続く洗浄ハンドル32の回動操作によって、作用レバー34が上記とは逆方向に回動運動し、排水弁を引張って開弁させ、小洗浄動作を行わせる。   On the other hand, when the cleaning handle 32 is rotated clockwise in FIG. 1, that is, a small cleaning operation is performed, as shown in FIG. 6C, the contact portion 100-1 is brought into contact with the contacted portion 76-2. The contact part 100-2 and the contact part 100-3 are simultaneously in contact with the contact part 76-3, the contact part 76-4, and the contact part 76-1, respectively. The operation lever 34 is rotated in the direction opposite to the above by the subsequent rotation operation of the cleaning handle 32 after the contact, and the drain valve is pulled and opened to perform a small cleaning operation.

一方、図7は施工誤差等によって駆動軸78と従動軸74とがそれぞれ軸線が不一致の状態で取り付けられた状態、即ち従動軸74の軸線に対して、駆動軸78の軸線が相対的に偏った位置に取り付けられた状態を表している。   On the other hand, FIG. 7 shows a state in which the drive shaft 78 and the driven shaft 74 are attached with their axes inconsistent due to construction errors or the like, that is, the axis of the drive shaft 78 is relatively deviated from the axis of the driven shaft 74. It shows the state attached to the position.

この場合、例えば当接部100-1が両隣の被当接部76-1,76-2のうちの一方の被当接部76-1側に偏って位置し、また当接部100-2が両隣の被当接部76-2,76-3のうちの一方の被当接部76-2側に偏って位置し、更に当接部100-3が両隣の被当接部76-3,76-4のうちの一方の被当接部76-4の側に偏って位置し、更に当接部100-4が両隣の被当接部76-4,76-1のうちの一方の被当接部76-1側に偏って位置した状態となる。   In this case, for example, the abutting portion 100-1 is biased to the one abutted portion 76-1 side of the adjacent abutted portions 76-1 and 76-2, and the abutting portion 100-2. Is located biased toward one of the abutted portions 76-2 of the abutting portions 76-2 and 76-3 on both sides, and the abutting portion 100-3 is located on the abutting portion 76-3 on both sides. , 76-4 is biased toward one of the abutted portions 76-4, and the abutting portion 100-4 is one of the abutting portions 76-4 and 76-1 adjacent to each other. It will be in the state of being biased and located on the contacted part 76-1 side.

従ってこの状態で洗浄ハンドル32を図1において反時計方向に回動操作すると、図7(B)に示しているように当接部100-1,100-3,100-4が対応する被当接部76-1,76-3,76-4に当接する前に、当接部100-2がいちはやく被当接部76-2に当接し、その後の引続く洗浄ハンドル32の回動操作に伴って、駆動軸78から従動軸74へと回動運動を伝達し、更に従動軸74から作用レバー34へと回動運動を伝達せしめる。   Accordingly, when the cleaning handle 32 is rotated counterclockwise in FIG. 1 in this state, the contact portions 100-1, 100-3, and 100-4 correspond to the corresponding contact portions as shown in FIG. 7B. Before contacting the contact portions 76-1, 76-3, 76-4, the contact portion 100-2 immediately contacts the contacted portion 76-2, and the subsequent cleaning handle 32 is rotated. Accordingly, the rotational motion is transmitted from the drive shaft 78 to the driven shaft 74, and the rotational motion is further transmitted from the driven shaft 74 to the action lever 34.

一方洗浄ハンドル32を図1において時計方向に回動操作すると、図7(C)に示しているように当接部100-3がいちはやく被当接部76-4に当接し、その後の引続く洗浄ハンドル32の回動操作に伴って、駆動軸78から従動軸74へと回動運動を伝達する。
以上のように、本実施形態では従動軸74と駆動軸78とが施工誤差無く正確に取り付けられている場合よりは、むしろそれらの位置に施工誤差があった方が、洗浄ハンドル32の回動操作に対する便器洗浄動作の応答性がより高まる特長を有している。
On the other hand, when the cleaning handle 32 is rotated in the clockwise direction in FIG. 1, the contact portion 100-3 immediately contacts the contacted portion 76-4 as shown in FIG. A rotational motion is transmitted from the drive shaft 78 to the driven shaft 74 as the cleaning handle 32 is rotated.
As described above, in this embodiment, rather than the case where the driven shaft 74 and the drive shaft 78 are accurately attached without any construction error, the rotation of the cleaning handle 32 is performed when there is a construction error at those positions. It has the feature that the responsiveness of the toilet cleaning operation to the operation is further increased.

以上は駆動軸78と従動軸74との位置誤差の一例を示したものであるが、駆動軸78と従動軸74とが施工時の位置誤差によって他の相対位置に位置した場合には、上記当接部100-1或いは当接部100-3以外の他の当接部が大洗浄時,小洗浄時においていちはやく対応する他の被当接部に当接し、上記と同様にして駆動軸78から従動軸74へと回動運動を伝達する。   The above shows an example of the position error between the drive shaft 78 and the driven shaft 74. However, when the drive shaft 78 and the driven shaft 74 are positioned at other relative positions due to the position error at the time of construction, The contact portion other than the contact portion 100-1 or the contact portion 100-3 comes into contact with the corresponding other contact portion at the time of large cleaning or small cleaning, and the drive shaft 78 is the same as described above. Rotating motion is transmitted from to the driven shaft 74.

本実施形態によれば、従来のように駆動軸78を挿通させる前板16側の挿通孔を駆動軸78に対して位置合せする作業を行うことなく、駆動軸78の取付けを行うことができる利点を有する。   According to this embodiment, the drive shaft 78 can be attached without performing the operation of aligning the insertion hole on the front plate 16 side through which the drive shaft 78 is inserted with respect to the drive shaft 78 as in the prior art. Have advantages.

従来にあっては、図13の比較例図に示しているように、前板16に4角形状の貫通の大きな開口部200を設けて、その開口部200において、調整金具204の一方の金具204Aを前板16の前側に、他方の金具204Bを前板16の裏側に配置して、それらをねじ206にて締結し、一対の金具204A,204Bにて前板16を前後から挟持する状態に調整金具204を取り付けるとともに、調整金具204を開口部200において上下方向に位置移動させ、或いは金具204Aを長穴208において相対的に左右方向に位置移動させることで、金具204Aに設けた駆動軸212挿通のための挿通孔210の位置を、駆動軸212の位置に合せて調整するといったことを行っているが、本実施形態によればこのような調整金具204を用いた挿通孔210の位置調整を行うことを不要化できる。   Conventionally, as shown in the comparative example of FIG. 13, the front plate 16 is provided with a square-shaped opening 200 having a large through-hole, and one opening of the adjustment fitting 204 is provided in the opening 200. A state in which 204A is arranged on the front side of the front plate 16 and the other metal fitting 204B is arranged on the back side of the front plate 16, they are fastened by screws 206, and the front plate 16 is sandwiched from the front and rear by a pair of metal fittings 204A and 204B. At the same time, the adjustment fitting 204 is attached to the opening 200, and the adjustment fitting 204 is moved vertically in the opening 200, or the fitting 204A is moved relatively in the left-right direction in the elongated hole 208, so that the drive shaft provided in the fitting 204A is provided. Although the position of the insertion hole 210 for 212 insertion is adjusted according to the position of the drive shaft 212, according to this embodiment, such an adjustment metal fitting 2 4 can be required of that adjust the position of the insertion hole 210 with.

また本実施形態によれば、挿通孔210の位置調整のために前板16にこのような大きな4角形状の開口部200を設けておくといったことは必要でなくなるため、開口部200を隠蔽するための化粧プレート26を敢えて用いなくても、図9に示しているように洗浄ハンドル32を駆動軸78に連結させる状態に、前板16の前面に取り付けるといったことも可能となる(図3の軸受部材86の前板16からの突出量を小さくする等して)。   Further, according to the present embodiment, it is not necessary to provide such a large quadrangular opening 200 in the front plate 16 in order to adjust the position of the insertion hole 210, so the opening 200 is concealed. Even if the decorative plate 26 is not used, it is possible to attach the cleaning handle 32 to the drive shaft 78 as shown in FIG. For example, by reducing the amount of protrusion of the bearing member 86 from the front plate 16).

本実施形態では、駆動軸78と従動軸74とのそれぞれに当接部100-1〜100-4,被当接部76-1〜76-4を回動方向に等間隔で4個所に設けていることから、施工誤差等の吸収可能な範囲を広く確保できる利点を有する。
図8はその理由を具体的に表している。
In the present embodiment, the abutting portions 100-1 to 100-4 and the abutted portions 76-1 to 76-4 are provided at four positions at equal intervals in the rotation direction on each of the drive shaft 78 and the driven shaft 74. Therefore, it has an advantage that a wide range that can be absorbed such as construction errors can be secured.
FIG. 8 specifically shows the reason.

例えば図8(B)に示しているように駆動軸78から放射状に延びる当接部100-1,100-2,100-3を3本即ち3個所に設け、また対応する被当接部76-1,76-2,76-3を回動方向に3個所に設けた場合、駆動軸78の位置が図8(B)(II)において左右方向に移動すると、これとともに例えば当接部100-1と被当接部76-2との上下方向の間隔も自動的に狭まってしまい、施工誤差の吸収可能な範囲が狭くなってしまう。   For example, as shown in FIG. 8B, three contact portions 100-1, 100-2, and 100-3 extending radially from the drive shaft 78 are provided at three portions, that is, three corresponding contact portions 76. -1, 76-2, 76-3 are provided at three positions in the rotation direction, and the position of the drive shaft 78 moves in the left-right direction in FIGS. The vertical distance between -1 and the contacted portion 76-2 is also automatically narrowed, and the range in which construction errors can be absorbed is narrowed.

しかるに図8(A)に示しているように当接部100-1,100-2,100-3,100-4及び対応する被当接部76-1,76-2,76-3,76-4をそれぞれ4個所に設けておいた場合、駆動軸78が図8(A)(II)において左右方向に位置移動しても、各当接部と被当接部との上下方向の間隔は一定に維持され、施工誤差の吸収可能な範囲を広く確保することが可能である。
また施工誤差の吸収可能な範囲を同じとする場合には、従動軸74と駆動軸78との連係部分の形状を小型化でき、ひいては洗浄ハンドル装置28をより小型化することができる。
However, as shown in FIG. 8A, the contact portions 100-1, 100-2, 100-3, 100-4 and the corresponding contacted portions 76-1, 76-2, 76-3, 76 are provided. -4 provided at four locations, even if the drive shaft 78 moves in the left-right direction in FIGS. 8A and 8II, the vertical distance between each contact portion and the contacted portion. Is kept constant, and it is possible to secure a wide range in which construction errors can be absorbed.
When the range in which the construction error can be absorbed is the same, the shape of the link portion between the driven shaft 74 and the drive shaft 78 can be reduced in size, and the cleaning handle device 28 can be further reduced in size.

図10は本発明の他の実施形態を示している。
この例は、駆動軸78及び従動軸74の設置状態の下で、当接部100に隙間埋め部材118を取り付けるようになした例である。
具体的には、ここでは当接部100-2と100-4とに隙間埋め部材118を取り付け、そのことによって当接部100-2と被当接部76-2との間の隙間、更に当接部100-4と被当接部76-1との間の隙間を部分的に埋めるようになしている。
FIG. 10 shows another embodiment of the present invention.
In this example, the gap filling member 118 is attached to the contact portion 100 under the installation state of the drive shaft 78 and the driven shaft 74.
Specifically, here, the gap filling member 118 is attached to the contact portions 100-2 and 100-4, whereby the clearance between the contact portion 100-2 and the contacted portion 76-2, The gap between the contact part 100-4 and the contacted part 76-1 is partially filled.

このようになした場合、洗浄ハンドル32を大洗浄側,小洗浄側に回動操作したときに、当接部100-2から被当接部76-2への回動運動の伝達、或いは洗浄ハンドル32を小洗浄側に回動操作したときの当接部100-4から被当接部76-1への回動運動の伝達を速やかに行うことができ、洗浄ハンドル32の回動操作に対する便器洗浄動作の応答性を上記の実施形態に比べて高くすることが可能である。   In this case, when the cleaning handle 32 is rotated to the large cleaning side and the small cleaning side, the rotation movement is transmitted from the contact part 100-2 to the contacted part 76-2, or the cleaning is performed. When the handle 32 is rotated to the small cleaning side, the rotational movement can be quickly transmitted from the contact portion 100-4 to the contacted portion 76-1, and the cleaning handle 32 can be rotated. The responsiveness of the toilet bowl cleaning operation can be increased as compared with the above embodiment.

尚ここでは当接部100-2と100-4とのそれぞれに隙間埋め部材118を取り付けているが、当接部100-1〜100-4の全てに、かかる隙間埋め部材118を取り付けるようになしても良いし、或いは隙間埋め部材118を被当接部76-1〜76-4の何れか又は全てに取り付けるようになすこと、更には図10(A)では隙間埋め部材118が当接部と被当接部との間の隙間を部分的に埋めるものとなしてあるが、その隙間を全体的に埋めるような形態で隙間埋め部材118を取り付けるといったことも可能である。   Here, the gap filling member 118 is attached to each of the contact portions 100-2 and 100-4. However, the gap filling member 118 is attached to all of the contact portions 100-1 to 100-4. Alternatively, the gap filling member 118 may be attached to any or all of the abutted portions 76-1 to 76-4, and the gap filling member 118 is in contact with the contact portion 76-1 in FIG. 10A. The gap between the part and the contacted part is partially filled, but the gap filling member 118 may be attached in such a manner that the gap is entirely filled.

本発明においては、駆動軸78側の当接部,従動軸74側の被当接部を上例以外の他の様々な形態で設けることが可能である。
図11,図12はその具体的な一例を示している。
図11(A)の例は、従動軸74に上記のような平板部75を設けるのに代えて、従動軸74から90°間隔で4本のアーム120を放射状に延び出させ、そしてそれぞれの先端に被当接部76-1〜76-4を屈曲形状で且つ軸方向に延びる形態に設けた例である。
In the present invention, the abutting portion on the drive shaft 78 side and the abutted portion on the driven shaft 74 side can be provided in various forms other than the above example.
11 and 12 show a specific example.
In the example of FIG. 11A, instead of providing the flat plate portion 75 as described above on the driven shaft 74, the four arms 120 extend radially from the driven shaft 74 at intervals of 90 °, and This is an example in which the abutted portions 76-1 to 76-4 are provided at the tip in a bent shape and extending in the axial direction.

また図11(B)の例は、駆動軸78の先端に大径の円板状の板状部122を設けて、その板状部122の回動方向の4個所に穴部124-1〜124-4を設け、穴部124-1〜124-4のそれぞれに、対応する被当接部76-1〜76-4を挿入させ、それら穴部124-1〜124-4の回動方向の一方の端部を、洗浄ハンドル32の大洗浄時の当接部124-1A〜124-4Aとなし、また他方の端部を小洗浄時における当接部124-1B〜124-4Bとなした例である。
尚、穴部124-1〜124-4については予想される誤差を見込んで適宜にその寸法や形状を定めておくことができる。
In the example of FIG. 11B, a large-diameter disk-like plate-like portion 122 is provided at the tip of the drive shaft 78, and holes 124-1 to 12-4 are provided at four locations in the rotational direction of the plate-like portion 122. 124-4 is provided, and the corresponding abutted portions 76-1 to 76-4 are inserted into the holes 124-1 to 124-4, and the rotation directions of the holes 124-1 to 124-4 are inserted. One end portion of the cleaning handle 32 is made into contact portions 124-1A to 124-4A at the time of large cleaning, and the other end portion becomes contact portions 124-1B to 124-4B at the time of small cleaning. This is an example.
It should be noted that the sizes and shapes of the holes 124-1 to 124-4 can be appropriately determined in anticipation of an expected error.

更に図12の例は、駆動軸78から棒状をなす当接部100-1〜100-4を、軸直角方向外方に進むにつれて従動軸74側に接近するように斜めに延び出させる一方、従動軸74側からも同じく棒状部を駆動軸78側に斜めに延び出させて、それらを被当接部76-1,76-2,76-3,76-4となし、それら当接部100-1〜100-4と被当接部76-1〜76-4とを回動方向に当接させるようになした例である。
その他本発明では当接部,被当接部を上例以外の他の様々な形態で構成することが可能である。
Furthermore, in the example of FIG. 12, the contact portions 100-1 to 100-4 that form a rod shape from the drive shaft 78 are extended obliquely so as to approach the driven shaft 74 side as they go outward in the direction perpendicular to the axis. Similarly, the rod-shaped portion is also obliquely extended from the driven shaft 74 side to the drive shaft 78 side to form the contacted portions 76-1, 76-2, 76-3, and 76-4. This is an example in which 100-1 to 100-4 and the abutted portions 76-1 to 76-4 are brought into contact with each other in the rotation direction.
In addition, in the present invention, the contact portion and the contacted portion can be configured in various forms other than the above examples.

以上本発明の実施形態を詳述したがこれらはあくまで一例示である。
例えば上例では従動軸74を作用レバー34のレバー軸36と独立して設けているが、作用レバー34の配置の向き如何によっては、かかる作用レバー34のレバー軸36に従動軸74を一体に構成しておくこといったことも可能であるし、また上例では作用レバー34がレバー軸36の軸線周りに回動運動するようになしてあるが、場合によって作用レバー34をレバー軸36の軸線と直交する軸の軸線周りに上下回動可能とし、その回動に基づいて排水弁を引き上げて開弁動作させるように構成しておくといったことも可能である。
Although the embodiments of the present invention have been described in detail above, these are merely examples.
For example, in the above example, the driven shaft 74 is provided independently of the lever shaft 36 of the action lever 34. However, depending on the orientation of the action lever 34, the follower shaft 74 of the action lever 34 is integrated. Although it is possible to configure the operation lever 34 in the above example, the operation lever 34 rotates around the axis of the lever shaft 36. In some cases, the operation lever 34 is moved to the axis of the lever shaft 36. It is also possible to make it possible to turn up and down around the axis of the axis perpendicular to the axis, and to open the valve by raising the drain valve based on the turning.

更に本発明では、場合によって駆動軸78,従動軸74の一方については当接部又は被当接部を1個所だけに設けておくといったことも可能であるし、更に図2に示す駆動軸78側の棒状の当接部を従動軸74側に被当接部として設け、また従動軸74側の突出形状の被当接部を駆動軸78側の当接部として設けておくといったことも可能である。
その他本発明は、内側タンクとこれを包み込む外側タンクとの2重タンク構造をなすタンクの洗浄ハンドル装置に対して適用することも可能である等、本発明はその趣旨を逸脱しない範囲において種々変更を加えた形態で構成可能である。
Furthermore, in the present invention, depending on the case, it is possible to provide a contact portion or a contacted portion for only one of the drive shaft 78 and the driven shaft 74, and the drive shaft 78 shown in FIG. It is also possible to provide a rod-like contact portion on the side as a contact portion on the driven shaft 74 side, and a protruding contact portion on the driven shaft 74 side as a contact portion on the drive shaft 78 side. It is.
In addition, the present invention can be applied to a cleaning handle device for a tank having a double tank structure of an inner tank and an outer tank that wraps the inner tank. The present invention can be variously modified without departing from the spirit of the present invention. It can be configured in a form to which is added.
