閉動作中，即使返覆由手按壓馬桶座或是馬桶蓋的等的動 作，最終段的輸出軸及旋轉軸也不會偏離旋轉軸方向。因 此，最終段的輸出軸及旋轉軸的位置關係因爲不偏離，所 以無功能零件收納筒等的干渉，無自動開閉裝置的性能悪 化。 對於申請專利範圍第2 5項，因爲藉由螺絲彈簧將馬 -9 - (6) (6)200418425 桶座或是馬桶蓋往開放側推迫的手段插入馬桶座的自動開

圓的外接線內。由此，設置於驅動馬達的輸出軸的小齒輪 及與遊星齒輪機構的恒星齒輪一體設置的大齒輪因爲可以 配置於同一平面，所以在馬達的深度及遊星齒輪機構的深 度之中較厚方的深度，可由加上連結驅動馬達的輸出軸及 遊星齒輪機構的輸入軸的減速齒輪列的大齒輪或是小齒輪 的片方的厚度的深度構成自動開閉裝置。且，連結驅動馬 達的輸出軸及遊星齒輪機構的輸入軸的減速齒輪列的軸心 -10- (7)

第1圖是本發明的馬桶座裝置的立體圖。在圖中，利 用馬桶本體（無圖示）的背部側的墊環的上面固定暖房馬 桶座裝置1 〇的外殼1 1，將馬桶座1 2及馬桶蓋1 3可分別 開閉自如在地裝於此外殼1 1。 在馬桶座12及馬桶蓋13，將轉動塊體插入部12a、 1 3 a分別設置於各基端部。 在轉動塊體插入部12a、13a，將馬桶座12及馬桶蓋 1 3自動地開閉用的自動開閉裝置3 0 (詳細是後述）是被 插入。然而，說明的方便上，以下，雖說明圖上右側的馬 桶座1 2及自動開閉裝置3 0、外殼1 1的連結關係，但是 與左側的馬桶蓋1 3自動的開閉裝置3 0、外殼1 1的連結 關係也是同樣的結構。（在馬桶蓋的情況中，以下替換所 說明的馬桶座的構成要素及馬桶蓋的構成要素。） 自動開閉裝置3 0的功能零件收納筒3 1是旋轉塊體插 入部12a、13a之中對於塊體插入部12a不能轉動地插入 (藉由將固定用塊體3 1 a嵌入於功能零件收納筒3 1的外 -13- (10) (10)200418425 周使功能零件收納筒3 1具有方向性，進一步藉由將與固 定塊體3 1 a的外形略同一形狀的插入部設置於插入部1 2 a 就可以不可旋轉），可旋轉地被插入塊體插入部1 3 a °從 自動開閉裝置3 0突出的旋轉軸40雖是在支撐塊體1 4的 鉸鏈軸插入部1 4c是不能轉動地被插入固定，但是對於旋 轉軸40，功能零件收納筒3 1因爲可轉動自如，所以馬桶 座1 2、馬桶蓋1 3是對於外殼1 1可轉動自如地動作。 在外殼1 1的前面側是形成供插入支撐塊體1 4用的突 部11a，在支撐塊體14的下方形成插入孔14a。由此在突 部11a插入支撐塊體14。然而，此支撐塊體14及突部 1 la的裝卸機構是可以使用日本特開平10-25 8003號所詳 細記’載機構。 如第2圖或是第3圖所示，從自動開閉裝置3 0的一 端拉出束有電力線及訊號線的電配線5 0，在其電配線5 0 的先端設有連接器51，並與設置在從外殼11內部的控制 器引出的電配線5 2的先端的連接器5 3結合。 第4圖顯示自動開閉裝置3 0的剖面圖，第5圖顯示 分解立體圖。如圖示，自動開閉裝置3 0，是由：在一端 具有電配線取出孔3 1 b且開放他端的圓筒狀的功能零件收 納筒3 1、將功能零件收納筒3 1及馬桶座1 2不可旋轉地 固定用的固定用塊體31a、由DC電刷馬達等構成的驅動 馬達32、構成減速齒輪列的遊星齒輪機構33 (在本實施 例中爲直列3段），設定以上的負荷施加於旋轉軸4 0的 情況時使負荷不傳達至減速齒輪列用的扭矩限制器機構 -14- (11) (11)200418425 3 4、檢測馬桶座1 2的旋轉位置的電位計3 5、具有插入旋 轉軸40的插入孔36b的軸承36、將馬桶座12隨時朝開 方向推迫的扭力彈簧3 7、與功能零件收納筒3 1不可旋轉 地固定的彈簧承座3 8、將彈簧承座3 8固定於功能零件收 納筒3 1內用的固定構件3 9所構成。在功能零件收納筒 3 1的開放端內周中設有將前述固定構件3 9螺入用的母螺 栓，在母螺栓的深側設有使內齒輪3 3 a (後述）及彈簧承 座3 8不可旋轉用的鋸齒。 將恒星齒輪32a壓入驅動馬達32的輸出軸，就可與 後述遊星齒輪機構3 3機械地連結。 接著使用第6圖說明使用於自動開閉裝置3 0的減速 齒輪列遊星齒輪機構3 3。 遊星齒輪機構3 3，是由：設置於功能部收納筒3 1的 內周的內齒輪33a、及與其嚙合的複數的遊星齒輪33b… 、及與此遊星齒輪3 3 b嚙合的恒星齒輪3 3 c所構成。上述 遊星齒輪33b，是藉由從恒星齒輪33c的背面突出的突軸 3 3 d ···分別可旋轉（自轉）自如地軸支。突軸3 3 d是由預 定間隔呈環狀，由例如1 2 0 °間隔設置3根，安裝有3個 遊星齒輪33b。 然而，藉由設置將前述突軸33d的先端部分一體化用 的固定孔3 3 f…及具有恒星齒輪插入孔33g的蓋33e，就 可將遊星齒輪33b…元件化成遊星齒輪機構33。 接著使用第7圖說明使用於自動開閉裝置3 0的扭矩 限制器機構3 4。 -15- (12) (12)200418425 扭矩限制器機構3 4，是由不可旋轉地固定在最終段 的遊星齒輪機構33的太陽齒輪33c的扭矩傳達齒輪34a 及摩擦齒輪34b所構成。扭矩傳達齒輪34a是形成附緣的 圓盤狀，在中央設有與太陽齒輪33c的表側突軸33h略同 一形狀的孔34c，在緣部內側設置傳達突起34d。摩擦齒 輪3 4b是由十字形狀的橡膠等的彈性體形成，外側突起 34e是在預定負荷內承受來自傳達突起34d的旋轉力，超 過預定負荷的話，外側突起34e是藉由傳達突起34d變形 而不會將旋轉力傳達至摩擦齒輪34b。然而，在摩擦齒輪 34b的中央設置動力傳達用突起34f。 馬桶座2的絕對位置，是藉由組裝於扭矩限制器機構 3 4及軸承3 6 (後述）之間的電位計3 5檢測。電位計3 5 是由安裝於軸承36的1枚的印刷電路基板35a及設置於 彈簧承座3 8的一端的位置的電刷3 5 b由所構成。在印刷 電路基板3 5 a上，形成同心圓狀的圖案部、印刷阻力部。 然而，印刷阻力部的中心角是與馬桶座的開閉時的轉動角 度對應。而且，位置電刷3 5 b，是在先端部分，與圖案部 及印刷阻力部滑動地接觸而導通電。馬桶座1 2轉動的話 ，軸承3 6會隨著轉動，對於印刷電路基板3 5 a的位置電 刷3 5b的位置因爲變動，所以將其電地檢測來檢測馬桶座 1 2的位置。 軸承36是在一端設置摩擦齒輪34b的傳達用突起 34f及不可旋轉地結合用的卡合孔36a，在他端設置馬桶 座12的旋轉軸40及不可旋轉地結合用的卡合孔3 6b。 (13) (13)200418425 扭力彈簧3 7，一端是固定於軸承3 6，他端是固定於 彈簧承座3 8，藉由扭力將馬桶座1 2往開放側推迫（實際 是抵抗由扭力彈簧3 7所產生的推迫力使馬桶座1 2藉由自 ， 重閉止）。 彈簧承座3 8是設有將扭力彈簧3 7固定於內周的固定 部，在外周設置鋸齒。 防止脫落防止用的固定構件39，是在其外周切成公 螺紋，並與功能零件收納筒3 1內面的母螺栓螺合來將前 述各零件收納於功能零件收納筒3 1內而一體化。 # 藉由上述結構，驅動馬達3 2的旋轉力是透過安裝於 驅動馬達32的輸出軸的恒星齒輪32a>>第1遊星齒輪機 構（遊星齒輪33b )(自轉 >>公轉）>>恒星齒輪33c>>第

饋控制事實現緩和的開閉動作。 本實施例的自動開閉裝置，是因爲將驅動馬達3 2的 · 旋轉力透過遊星齒輪機構33傳達至座蓋的旋轉軸40，所 · 以在同心上可以配置驅動馬達3 2及遊星齒輪機構3 3及旋 轉軸4 0，對於與旋轉軸4 〇的軸心相互垂直的投影面可將 裝置本身的外形旋轉軸4〇形成同心圓形狀。因此，因爲 -17- (14) (14)200418425 利用溫水洗淨馬桶座的座蓋的開閉多的緩閉止元件等的互 換容易，所以對於溫水洗淨馬桶座的自動開閉裝置的收納 設計成爲非常容易。 且，藉由將驅動馬達3 2的輸出軸及遊星齒輪機構3 3 的恒星齒輪3 3 c的旋轉軸、及多段並列的遊星齒輪機構的 恒星齒輪3 3 c的軸心彼此，分別同心配置，就可將自動開 閉裝置的減速機構小型化。 進一步，因爲將馬桶座1 2或馬桶蓋1 3的旋轉軸4 0 及驅動馬達3 2的輸出軸呈同心配置，所以裝置本身的安 裝面積小，且因爲可在馬桶座1 2或是馬桶蓋1 3的旋轉軸 4〇的下方設置其他的功能零件，所以可不將溫水洗淨馬 桶座大型化地搭載自動開閉裝置。因爲將此遊星齒輪機構 3 3呈複數段直列配置，所以驅動馬達3 2及遊星齒輪機構 3 3是可利用比較小型。 進一步，因爲在遊星齒輪機構3 3的最終段的輸出軸 3 3h及旋轉軸40之間設有扭矩限制器機構34 ’所以即使 在自動開閉動作中由手按壓馬桶座1 2或是馬桶蓋1 3等， 負荷施加在旋轉軸側的情況，也不會增加負荷於遊星齒輪 機構3 3。 且，在其位置，因爲設有檢測馬桶座1 2或馬桶盖1 3 的開閉狀態的電位計3 5，所以即使欠缺齒輪的齒等’座 蓋12、13的開閉位置也不會偏離’使安定動作成爲可能 〇 然而，藉由將遊星齒輪機構33形成與驅動馬達32的 -18- (15) (15)200418425 外徑略同一，就可將驅動馬達32的發生扭矩及遊星齒輪 機構3 3的減速比設計成最適合的平衡，且形成需要最小 限度的大小。 進一步，因爲由複數的遊星齒輪33b構成遊星齒輪機 構3 3，所以各遊星齒輪3 3 b可以分散所受到負荷，將1 個1個遊星齒輪的破壞強度可以設計較小。然而，將承受 遊星齒輪33b的公轉的恒星齒輪33c的3個突軸33d呈等 間隔設置’就可使恒星齒輪3 3 c安定地旋轉。 接著，第8圖是顯示本發明的自動開閉裝置的第2實 施例。然而與第1實施例同一的功能者，附加與第1實施 例同一符號。 在本實施例中是將作爲驅動馬達3 2及減速齒輪列的 遊星齒輪機構33使用平齒輪60a、60b機械地連結。如此 爲了傳達驅動馬達32的動力而由使用平齒輪60a、60b就 可將驅動馬達3 2及減速齒輪列及旋轉軸40配置成平行’ 即使在馬桶座1 2或是馬桶蓋1 3的自動開閉裝置3 0的俱1J 方因爲也可設置其他的功能零件，所以收納設計的變形例 是更廣。且，因爲平行地傳達驅動馬達3 2的動力，所以 非平齒輪而使用斜齒齒輪或人字齒輪等也可以。 接著，第9圖是顯示本發明的自動開閉裝置的第3實 施例。然而與第1實施例同一的功能者’附加與第1實施 例同一符號。 在本實施例中是將作爲驅動馬達3 2及減速齒輪列的 遊星齒輪機構3 3使用蝸輪齒輪6 1機械地連結。然而’〃 -19- (16) (16)200418425 蝸輪齒輪61嚙合的第！段的遊星齒輪機構33的突軸33d 不是平齒輪形狀而是斜齒齒輪形狀。如此傳達驅動馬達 32的動力的因爲是使用蝸輪齒輪61，因爲是可垂直或是 錯開配置驅動馬達3 2及減速齒輪列及旋轉軸4 0，所以在 馬桶座1 2或是馬桶蓋1 3的自動開閉裝置3 0的側方或是 下方也可設置其他的功能零件，使收納設計的變形例更廣 〇 且’爲了垂直或是錯開地傳達驅動馬達32的動力’ 使用直齒傘輪、螺旋歯傘齒輪、平齒輪、準雙曲面齒輪、 螺絲齒輪等也可以。 接著’第10圖是顯不本發明的自動開閉裝置30的第 4實施例。然而與第1實施例同一的功能者，附加與第1 實施例同一符號。 · 在本實施例中是將驅動馬達3 2及作爲減速齒輪列的 遊星齒輪機構33捲架在使用傳達手段（由小帶輪2a、大 帶輪2b、確動皮帶63c構成）機械地連結。爲了如此傳

The bearing 36 is a transmission protrusion 34f provided with a friction gear 34b at one end and an engagement hole 36a for non-rotatably coupling, A rotation shaft 40 of the toilet seat 12 and an engaging hole 36b for non-rotatably combining are provided at the other end. (13) (13) 200418425 Torsion spring 3 7, One end is fixed to the bearing 3 6, The other end is fixed to the spring bearing 3 8, The toilet seat 12 is pushed to the open side by torsion (actually, the toilet seat 1 2 is resisted by the torsion force generated by the torsion spring 37, Reclosed). The spring seat 38 is provided with a fixing portion for fixing the torsion spring 37 to the inner periphery. Zigzag is set on the periphery. Fixing member 39 for preventing fall-off, Is cut into male threads on its periphery, These components are screwed together with female bolts on the inner surface of the functional component storage cylinder 31 to store the aforementioned components in the functional component storage cylinder 31 and integrated. # With the above structure, The rotational force of the drive motor 32 is transmitted through the sun gear 32a mounted on the output shaft of the drive motor 32. > 1st planetary gear mechanism (starring gear 33b) (rotation > > Revolution) > > Stellar gear 33c > > 2nd planetary gear mechanism (starring gear 33b) (rotation > > Revolution) > > Stellar gear 33c > > Final stage planetary gear mechanism (starring gear 33b) (rotation > > Revolution) > > Stellar gear 33c > > Torque limiter mechanism 34 (torque transmitting gear 34a) > > Friction gear 34b > > Spring Bearing 36 > > The rotation axis 4 〇 is transmitted to the toilet seat 1 2 Open and close the toilet seat 12. however, The opening and closing angle of the toilet seat ® 1 2 is detected by a potentiometer 3 5. The drive motor 32 is controlled to perform a gentle opening and closing operation by the feedback control. The automatic opening and closing device of this embodiment, This is because the rotational force of the drive motor 32 is transmitted to the rotary shaft 40 of the cover through the planetary gear mechanism 33, Therefore, the driving motor 32, the planetary gear mechanism 33, and the rotating shaft 40 can be arranged on the concentric axis. For the projection plane perpendicular to the axis of the rotation axis 40, the external rotation axis 40 of the apparatus itself can be formed into a concentric circle shape. therefore, Because -17- (14) (14) 200418425 wash the seat cover of the toilet seat with warm water, it is easy to exchange the slow-closing stop elements, etc. Therefore, the storage design of the automatic opening and closing device for washing the toilet seat in warm water becomes very easy. And The output shaft of the drive motor 3 2 and the rotating shaft of the sun gear 3 3 c of the planetary gear mechanism 3 3, And the axes of the stellar gears 3 3 c of the multi-parallel planetary gear mechanism, Configured concentrically, This makes it possible to miniaturize the reduction mechanism of the automatic opening and closing device. further, Because the rotating shaft 4 0 of the toilet seat 12 or the toilet cover 13 and the output shaft of the driving motor 32 are arranged concentrically, So the installation area of the device itself is small, And because other functional parts can be provided below the rotating shaft 4 of the toilet seat 12 or the toilet lid 1 3, Therefore, an automatic opening / closing device can be installed without increasing the size of the toilet seat with warm water. Because this planetary gear mechanism 3 3 is arranged in a plurality of sections in line, Therefore, the drive motor 32 and the planetary gear mechanism 33 can be used relatively small. further, Since the torque limiter mechanism 34 'is provided between the output shaft 33h and the rotating shaft 40 of the final stage of the planetary gear mechanism 33, the toilet seat 12 or the toilet cover 13 can be pressed by hand even during the automatic opening and closing operation , When a load is applied to the rotation shaft side, It will not increase the load on the planetary gear mechanism 3 3. And In its place, Because a potentiometer 3 5 is provided to detect the open or closed state of the toilet seat 12 or the toilet lid 1 3, So even if you do n’t have gear teeth, etc. ’ The opening and closing position of 13 will not deviate from ’, which enables stable operation. 〇 However, By forming the planetary gear mechanism 33 to have an outer diameter of -18- (15) (15) 200418425 which is slightly the same as that of the drive motor 32, Then, the generated torque of the drive motor 32 and the reduction ratio of the planetary gear mechanism 33 can be designed to an optimal balance. And the formation requires a minimum size. further, Because the planetary gear mechanism 33 is composed of a plurality of planetary gears 33b, So each planetary gear 3 3 b can distribute the load. The breaking strength of one planetary gear can be designed to be small. however, By setting the three protruding shafts 33d of the sun gear 33c which undergoes the revolution of the sun gear 33b at equal intervals', the sun gear 3 3c can be stably rotated. then, Fig. 8 shows a second embodiment of the automatic opening and closing device according to the present invention. However, the same function as the first embodiment, The same symbols as those of the first embodiment are assigned. In this embodiment, the planetary gear mechanism 33 as the drive motor 32 and the reduction gear train uses a flat gear 60a, 60b is mechanically linked. In order to transmit the power of the drive motor 32, the flat gear 60a, 60b, the drive motor 32, the reduction gear train, and the rotating shaft 40 can be arranged in parallel. Even in the toilet seat 12 or the toilet cover 1 3, the automatic opening and closing device 3 of the 0 1J can also be provided with other functional parts , Therefore, the modification of the storage design is wider. And Because the power of the drive motor 32 is transmitted in parallel, Therefore, instead of a flat gear, a helical gear or a herringbone gear may be used. then, Fig. 9 shows a third embodiment of the automatic opening and closing device according to the present invention. However, those having the same function as the first embodiment are assigned the same reference numerals as those in the first embodiment. In this embodiment, the planetary gear mechanism 3 3 as a drive motor 32 and a reduction gear train is mechanically connected using a worm gear 61. However, ‘〃 -19- (16) (16) 200418425 the first of the worm gear 61 meshes! The protruding shaft 33d of the segmented planetary gear mechanism 33 is not a flat gear shape but a helical gear shape. Because the power of the drive motor 32 is transmitted in this way, the worm gear 61 is used. Because the drive motor 3 2 and the reduction gear train and the rotation axis 40 can be arranged vertically or staggered, Therefore, other functional parts can also be provided on the side or below the automatic opening and closing device 30 of the toilet seat 12 or the toilet lid 13. Variations of the storage design are wider. ‘For the purpose of transmitting the power of the drive motor 32 vertically or staggered’, use a straight toothed wheel, Spiral bevel gear, Flat gear, Hypoid gears, Screw gears, etc. are also possible. Next, Fig. 10 shows a fourth embodiment of the automatic opening and closing device 30 according to the present invention. However, the same function as the first embodiment, The same symbols as those of the first embodiment are added. In this embodiment, the drive motor 32 and the planetary gear mechanism 33 as a reduction gear train are used in a roll conveying means (by a small pulley 2a, Large pulley 2b, The securing belt 63c is configured to be mechanically connected. In order to convey the power of the drive motor 32 in this manner, the use of a reel transmission means, Because the drive motor 32 and the reduction gear train 3 3 are set at appropriate distances, Therefore, the drive motor or the reduction gear train of the toilet seat or the automatic opening and closing device of the toilet seat and the rotation shaft 40 are set to δ ten degrees of freedom fcn. And Because there is no sound of the small pulley 2a and gears, And can achieve mute. And Surely move the belt 63c, Can use flat belt, V belt, Attached hides, etc. are also available. then, Fig. 11 shows the automatic opening-closing device -20 of the first embodiment-(17) (17) 200418425 3 0 as the automatic opening-closing device 3 0 a of the toilet seat 12 and the automatic opening-closing device 3 Ob of the toilet cover 3 Ob Example of a parallel configuration. In this way, the automatic opening / closing device 3a of the toilet seat and the automatic opening / closing device 3 Ob of the toilet seat are integrated into one storage according to the relationship of the other functional units in the toilet seat device 10. The storage design can be made easier. however, In the case of intensive storage in one side, as shown in FIG. 12, the automatic opening and closing device 3 0a of the toilet seat 12 and the automatic opening and closing device 3 Ob of the toilet lid 1 3 can be integrated into a functional component storage cylinder 31. Therefore, miniaturization of the automatic opening and closing device can be achieved, And cost reduction. then, Fig. 13 shows a fifth embodiment of the automatic opening and closing device 30 of the present invention. However, the same function as the first embodiment, The same symbols as those of the first embodiment are added. In this embodiment, the automatic opening / closing device 30a of the toilet seat 12 is connected to the rotary shaft 40a, the protruding shaft 33d of the planetary gear 33, and the flat gear 60a. The automatic opening and closing device 30 of the first embodiment is used for the automatic opening and closing device 3 0b of the toilet seat 13 (the flat gear 60a is omitted), The automatic opening and closing device 30a and the automatic opening and closing device 30b are housed integrally. And The output shaft 40a of the automatic opening and closing device 30a of the toilet seat 12 and the output shaft 40b of the automatic opening and closing device 30b of the toilet seat 13 are coaxially arranged. Therefore, the rotating shaft 40a of the toilet seat 12 and the toilet cover 13 40b becomes 1 axis, It is very easy to make the design light and small around the rotation shaft 40. Following ‘Figure 14, 15, 16 is a sixth embodiment of the automatic opening and closing device 30 according to the present invention. However, the same function as the first embodiment, The same symbols as those in the first embodiment are assigned. -21-(18) (18) 200418425 In this embodiment, the automatic opening and closing device 3 0a of the toilet seat 12 and the automatic opening and closing device 3 Ob of the toilet cover 13 are integrated into one, And The output shaft 40a of the automatic opening and closing device 30a of the toilet seat 12 and the output shaft 40b of the automatic opening and closing device 30b of the toilet seat 13 are coaxially arranged. And The drive motor 32 of the automatic opening and closing device 30a of the toilet seat 12 and the automatic opening and closing device 30b of the toilet seat 13 are shared. And The driving of the automatic opening / closing device 3 0 a of the toilet seat 12 and the driving of the automatic opening / closing device 3 Ob of the toilet seat 13 are switched using a switching gear 62. This switching gear 62 is in the position shown in FIG. 14 because it is connected to the toilet seat 12 and the toilet cover 13 by a gear 62 driving motor 3 2. So the toilet seat 丨 2 and the toilet cover 1 3 are driven at the same time. At the position of Figure 15 Because only the toilet lid 3 is connected, so only the toilet lid 13 is driven, When in Figure 16, Since only the toilet seat 12 is connected, only the toilet seat 12 is driven. The movement of this switching gear 62 can be controlled by a solenoid valve (not shown) or the like. therefore, There is only one drive motor 32 for the automatic opening and closing device 30a of the toilet seat 12 and the automatic opening and closing device 30b of the toilet seat 13, and it is possible to achieve miniaturization of automatic opening and closing, And cost reduction. then, Figure 1 7 1 8. 19 is a modification of the sixth embodiment of the automatic opening and closing device 30 according to the present invention. However, the same function as the first embodiment, The same symbols as those in the first embodiment are assigned. In this embodiment, The output shaft 40a of the automatic opening and closing device 30a of the toilet seat 12 and the output shaft 40b of the automatic opening and closing device 30b of the toilet seat 13 are arranged in parallel.

圖所示在馬桶蓋用自動開閉裝置130的輸出軸140設置使 旋轉軸5 0不能轉動地插入固定的略長方形狀的連結孔 -30- (27) (27)200418425 141。且，在馬桶蓋用自動開閉裝置130的外殻131a使外 殼1 1的側壁1 1 b及供保持預定間隔用的轂部1 3 1 b及帽構 件lid的承受用突起131c設成一體。 接著，對於輔助元件8 0，使用第2 3圖、第2 9圖說 明。輔助元件8 0，是由：在自動開閉裝置3 0的旋轉軸4 0 不能轉動地連結的連結軸8 1、及爲了將馬桶座1 2朝開方 向推迫而使一端82a固定於連結軸81的輔助彈簧82、及 固定輔助彈簧82的他端82b的同時在外殼1 1不能轉動地 連結的連結蓋83、及與連結蓋83 —起包圍輔助彈簧82 的蓋84、及從馬桶座1 2將外殻1 1裝卸用的裝卸操作桿 85、及將輔助元件80固定於馬桶座12用的固定構件86 等所構成。 在連結軸8 1的先端部8 1 a (馬桶蓋1 3的支撐軸）形 成鋸齒，在略中央部分形成供規制連結軸8 1的推力方向 的移動用的大徑部81b。且，形成供密封與蓋84的內筒 部8 4a之間用的〇形環溝81c，在與大徑部81b及Ο形環 溝8 1c之間形成供一端插入輔助彈簧82用的插入孔81d 。且，形成密封與蓋8 3的內筒部8 3 a之間用的〇形環溝 81e，在末端部分形成與旋轉軸40的外形略同一形狀的溝 8 1卜 輔助彈簧82的一端82a是朝向中央曲折，插入插入 孔81d，他端82b是朝向中央曲折而固定在形成於連結蓋 83的內筒部83a的外周的支撐溝83b。然而支撐溝83b的 根部分是底部8 3 c的板厚稍增加而形成防止輔助彈簧8 2 -31 - (28) (28)200418425 的他端82b的轉動的防止壁83d。 且’在連結蓋8 3的後端，形成與在馬桶座用自動開 閉裝置3 0的外圍外殼3〗a 一體形成的卡合突起3 } q嵌合 並規制轉動的規制突起8 3 e，在規制突起的8 3 e的周緣部 分的一處形成規制裝卸操作桿的轉動的停止器8 3 f。且， 在外筒部8 3 g形成若干細徑化的細徑部8 3 h。在連結蓋8 3 的開口端使熔接用肋8 3 i形成於全周，將蓋8 4由超音波 熔接等一體化。 裝卸操作桿85，是由上方被切除的支撐圓筒85a及 下方被切除的裝卸用圓筒8 5 b形成，在其間形成內側及外 側若干板厚增加的環狀肋8 5 c。此環狀肋8 5 c的內徑是與 細徑部83h略同一徑且比外筒部83g小徑。且，在裝卸用 圓筒85b形成有把持用突起85d。 在固定構件8 6，形成：與連結軸8 1的外形略同一形 狀的連結用開口 8 6 a、爲了不能轉動地固定在馬桶座12 而沿著外周以預定間隔設置的突起8 6b、略L字形狀的連 結曲柄86c。且，在連結曲柄86c形成：締結螺栓用的下 孔86d。規制輔助元件80(除了固定構件86用的）的推 力方向的移動的停止器86e° 接著，參照第2 9圖，說明輔助兀件8 〇的組裝程序。 將〇形環收納於連結軸81的0形環溝81c、81e’將 輔助彈簧82的一端82a插入連結軸81的插入孔81d’將 他端82b卡合於連結蓋83的支撐溝83b將連結軸81插入 連結蓋8 3的內筒部8 3 a內’至與內筒部8 3 a的端部連結 -32- (29) (29)200418425 的軸8 1的大徑部8 1 b抵接爲止。由此使輔助彈簧82的他 端82b被收谷至防止壁83d內。 接著’將連結軸8 i的先端部8〗a插入蓋84的內筒部 8 4 a內’在蓋8 4的背側及連結蓋8 3的熔接用肋8 3 i相互 抵接的狀態下，藉由將蓋超音波振動而將連結軸8 1、輔 助彈簧82、連結蓋83、蓋84 —體化。 接著’雖將裝卸操作桿85插入外筒部83g，但是因 爲外筒部8 3 g是比環狀肋8 5 c若干大的徑，所以環狀肋 8 5 c是將外筒部8 3 g抬起插入至細徑部8 3 h爲止的話，連 結蓋83及裝卸操作桿85會被一體化，裝卸操作桿85是 由外筒部83g及環狀肋85c規制推力方向的脫落。接著藉 由將連結軸81插入固定構件86的連結用開口 86a內使輔 助元件8 0 —體化。 將此輔助元件80的連結軸81插通馬桶座12的連結 孔12d (第21圖參照）內，在將輔助元件80插入馬桶座 12的連結部12a內的狀態下，藉由將固定構件86的下孔 86d及馬桶座12的螺栓孔12c (第21圖參照）由自動攻 絲螺栓締結而使馬桶座1 2輔助的元件8 0 —體化。 然而，連結曲柄86c，因爲在裝設於馬桶座12之前 可朝外側彈性變形，所以輔助元件8 0 (除了固定構件8 6 )雖是可從固定構件8 6裝卸，但是裝設於馬桶座1 2之後 是藉由馬桶座1 2規制外側的變形，所以藉由與停止器 86e連結的蓋83的凸緣83j及輔助元件80(除了固定構 件8 6 )使推力方向的脫落被規制。 -33- (30) (30)200418425 且，裝卸操作桿85也同樣縮小連結曲柄86c及外筒 部83g的游隙並可越過外筒部83g程度地使裝卸操作桿 8 5不會朝外側變形來防止推力方向的脫落。 接著對於公差環62，使用如第3 0圖所示的原理圖說 明。公差環62，是如第3 0圖所示，形成具有波形狀部分 的環形狀，各波是作爲彈簧作用，其作用力是與波的變形 量成比例。在組裝時需要的力爲AF，半徑方向力爲RL ( N)，摩擦係數爲//，波數爲η，波的變形量爲c( mm) ，彈簧係數爲K ( N/mm)，傳達扭矩爲Mt，軸直徑爲d (m )的話，可以藉由 RL = n · c · K AF = RL · β Mt = AF · d/2 算出。 彈簧係數是可由變更材料的厚度、波之間距、寬、形 狀、高度設定，在正常時在旋轉軸40、140時最大程度的 扭矩是由實驗等求得，依據其扭矩選擇公差環62的形狀 〇 此設定扭矩以上的扭矩是發生於旋轉軸40的情況時 ，是公差環62的波形狀部62a是嵌入旋轉軸40、140的 連結孔而固定，且公差環的環狀緣部62b是滑動於載體 63的輸出軸63d的外周，設定扭矩以上的過重是不會施 加於自動開閉裝置30、130內部，而可防止齒輪的破損等 -34- (31) (31)200418425 如第3 1圖所示，驅動馬達3 2的軸是貫通馬達內部， 其徑是在內部比較粗，露出部分是形成細徑。將此先端部 3 2 a形成細徑的話，是爲了將齒輪3 2 b的齒數盡可能地減 少來使減速比變大。然而，雖也可將軸本身細徑化，但是 對於軸長，若軸是細的話，驅動馬達3 2的軸振動會變大 ’所以軸本身無法細徑化，只可將安裝有小齒輪32b的部 分細徑化。 接著，進行上述結構所產生的動作的說明。 第32圖是本發明的馬桶座裝置的控制方塊圖。由人 體檢測檢測器的檢測或是操作設在遙控器等的馬桶蓋打開 開關（無圖示）的話，使馬桶蓋用自動開閉裝置130內的 驅動馬達3 2通電’此驅動馬達3 2的旋轉，是透過減速齒 輪列（齒輪32b、第1齒輪34、第2齒輪37、第3齒輪 38、遊星齒輪機構）及公差環62、輸出軸140傳達至旋 轉軸5 0，而開放馬桶蓋1 3。 然而，藉由磁鐵61及設在區域檢測電路7 1的2個霍 爾I C 7 1 a、7 1 b檢測馬桶蓋1 3，是位在閉止區域（2 0度以 下）、轉動區域（20度〜80度）、開放區域（80度〜 1 1 〇度）、異常區域（1 1 0度以上）的那一區域，進行對 應各區域的驅動馬達3 2的通電控制（或是短路控制）。 進一步，由設在磁鐵 34c及旋轉檢測電路 70的霍爾 IC 7 0a，藉由檢測驅動馬達32的旋轉而可較正確地檢測是 位在區域內的那個位置’更可以進行詳細的通電控制。 且，設在遙控器等的馬桶座開開關的操作時’馬桶座 -35- (32) (32)200418425 用自動開閉裝置3 0內的驅動馬達3 2被通電，透過減速齒 輪列（小齒輪32b、第1齒輪34、第2齒輪37、第3齒 輪38、遊星齒輪機構）及公差環62使驅動馬達32的旋 轉傳達至旋轉軸4 0，開放馬桶座1 2。 然而，與馬桶蓋用自動開閉裝置1 3 0同樣，藉由旋轉 檢測電路7 0、區域檢測電路7 1檢測馬桶座1 2的位置， 進行對應位置的驅動馬達3 2的通電控制（或是短路控制 )° 在馬桶座12的內部中因爲設有暖房用的加熱器而較 重，只有與馬桶蓋用自動開閉裝置1 3 0同一構造的馬桶座 用自動開閉裝置3 0，因爲無法將馬桶座1 2抬起，所以設 置輔助元件80。此輔助元件80是內藏有一端與外殼11 一體化，他端與馬桶座1 2 —體化的輔助彈簧82。此輔助 彈簧82，在馬桶座1 2是在略垂直的狀態下是自然長，在 馬桶座1 2閉塞時中成爲扭曲的狀態。 因此，在馬桶座1 2閉塞時中可以發生開放側的扭矩 ，由此，即使與馬桶蓋用自動開閉裝置1 3 0略同一的構造 也可將馬桶座1 2抬起。 然而，輔助彈簧82的一端82a是藉由連結殻83的規 制突起8 3 e及安裝於外殼1 1的馬桶座用自動開閉裝置3 0 的卡合突起31q的卡合而與外殻11 一體化，輔助彈簧82 的他端82b是透過連結軸81、固定構件86而與馬桶座12 一體化。 操作設在遙控器等的馬桶座關閉開關（圖示無）的話 -36- (33) (33)200418425 ，與開動作相反的通電會施加於驅動馬達3 2，依據由旋 轉檢測電路7 0及區域檢測電路7 1所檢測的馬桶座1 2的 位置，進行通電控制（或是短路控制）。 由人體檢測檢測器（圖示無）所產生的遠離檢測或是 操作設在遙控器等的馬桶蓋關閉開關（無圖示）的話，與 馬桶座1 2同樣，使馬桶蓋用自動開閉裝置丨3 〇被控制， 就可以閉塞馬桶蓋1 3。 (產業上的利用可能性） ® 如以上，本發明的馬桶座或是馬桶蓋的自動開閉裝置 ，可使用於洋式馬桶的馬桶座或是馬桶蓋的自動開閉裝置 〇 本發明的自動開閉裝置，因爲可將裝置本身的安裝面 積縮小，也可在馬桶座或是馬桶蓋的旋轉軸下方設置其他

:連結孔As shown in Figure 25, the automatic opening and closing device 3 0 ′ is composed of a casing 3 1 (consisting of a main casing 3 1 a and a cover casing 3 1 b) forming a periphery, and a drive motor assembly A -24- (21) ( 21) 200418425, etc. As shown in FIG. 26, the drive motor assembly A is a drive motor 3 composed of a DC brush motor and the like. 2. The pinion gear 32b fixed by press-fitting the output shaft 32a of the drive motor 32, and fixed with bolts, etc. The first gear fixing spacer 33 of the drive motor 32, the first gear 34 having the large gear 34a meshing with the small gear 32b and the small gear 34b for transmitting power at the next stage, the rotating shaft 35 of the first gear 34, The first gear 34 fixed to the spacer 33 is constituted by a bearing 36. In the automatic opening and closing device 30, the ring magnet 34c is integrated with the surface (drive motor side) of the large gear 3 4a by joining or riveting, etc., and includes a large gear 37a meshing with the small gear 34b and the next stage. The second gear 37 of the pinion gear 37b for power transmission, the third gear 38 having a large gear 38a meshing with the pinion gear 37b, the third gear 38b for the next stage of the sun gear 38b for power transmission, the planetary gear set B, and the like. As shown in Fig. 27, the planetary gear set B 'is composed of: a rotating shaft 40, a ring magnet 6 fixed to the rotating shaft 40 for detecting the rotation position of the toilet seat 12, 1. When the above load is set When applied to the rotating shaft 40, a tolerance ring 62 functions as a torque limiter that prevents a load from being transmitted to the carrier 63, a carrier 63 connected to the rotating shaft 40 through the tolerance ring 62, and rotatably mounted on the carrier 63 The planetary gear 64 of the planetary shaft 63a, a bearing 65 that regulates the thrust direction of the planetary gear 64, an internal gear 66 that meshes with the planetary gear 64, a mounting spacer 67 that fixedly fixes the planetary gear mechanism to the casing 31a, etc. . However, as shown in FIGS. 25 to 26, the pinion gear 32b, the pinion gear 3 4b, and the pinion gear 37b are made of metal, and the pinion gear 34a and the pinion gear 37a are made of (22) 200418425 resin, and the pinion gear 3 2b and large Gear 3 4a, pinion 37a '疋 helical gear. Further, the large star gear 38b of the third gear 38 is integrally formed of metal, and the small gear 37b is a flat gear. Further, as shown in Figure 27, the internal gear 66 is made of resin. However, metal sintering such as metal gear knots or injection sintering, or integral molding of cold-forged resin gears can be formed by insert molding or the like. Even thinner than flat teeth, the helical gears can be used even if they are thinner. The gear itself may be thin, and the reduction gear train can be made lighter and lighter. In addition, by using the gears in the first and second rows of gears which can rotate at a relatively high speed, the backlash is small and transmission efficiency is improved. In addition, by making the meshing of the helical gear part with gold and resin (large gear), it is possible to suppress noise and the like due to wear. In addition, by reducing the speed of the high-torque, high-torque metal reduction gear, damage to the gear can be suppressed. Next, referring to Figs. 26 and 27, the assembly procedure is automatically opened. As shown in Fig. 26, the group program of the drive motor group A is performed. First, insert one end of the shaft 35 into the spacer 33a, insert the first gear 34 into the shaft 35, insert the shaft hole 36a of 36 of the shaft 35, insert the positioning hub 33b into the positioning hole, and tap the bolt (not shown) into the fixing hole. 36c and 36c are screwed into the lower hole 3 3 c of the spacer 3 3, and the spacer 34b and the large gear 3 8 a and the constant and large gear 3 8 ai wheel 6 4 are metal and can be burned by a punch, etc. Forming. And the contact with 〇 can ensure contact and ensure the strength of the gear. The gear train with a large contact area can generate the heat of the (pinion) or the closing device 3 and 4 of the 3 row. The end is inserted into the bearing 36b, and it will be fixed automatically. It will be integrated with the wheel 34, the shaft 35, and the bearing 36 by means of • 33, the first tooth -26- (23) 200418425. 32b Gear, fixed motor diameter, fixed hole. The motor is integrated in the process. 63a. Connect 6 5a through the through hole and the inner turbine. Further, drive the output shaft 32a of the drive motor 32 and the upper gear from the through hole 3 3 e of the spacer 3 3-pay attention to the meshing with the first gear 34 and the small 32b. Insert the bolt through the bolt insertion hole 36d (bearing 36) and the fixed hole 3 3d (separator 3 3), and complete the assembly by screwing into the bolt hole 32c provided in the drive 32. However, by forming the bolt insertion hole 36d, the fixing hole 33d on the side of the bolt insertion hole 36d which is larger than the bolt head is larger than the bolt head halfway (the position where the plate thickness is the same as that of the other solid 3 3 d). The diameter of the bolt can be penetrated to a degree that allows the two bolts for fixing the drive 32 to be shared. In this way, by reducing the first stage of the reduction gear train and the drive motor 32, it is possible to suppress shaft vibration and the like, thereby improving transmission efficiency. Next, the arrangement of the planetary gear set B will be described with reference to Figs. First, the planetary gear 64 is mounted on a planetary shaft provided on the carrier 63, and the internal gear 66 is mounted while paying attention to the fitting of the planetary gear 64. The end portion of the shaft 63a is mounted on a bearing recess provided in the bearing 65. In order to ensure the operation range of the planetary gear 64, the small-diameter cylindrical portion 63c of the spacer 63b provided on the carrier 63 is inserted through the 65b of the bearing 65 and riveted to the carrier 63, the planetary gear 64, and the bearing 65 gear 66. —Incorporating (hereafter, the person who integrates this is called "Star-toothing structure"). The tolerance ring 62 is fitted to the outer periphery of (24), (24) 200418425 of the output shaft 63d of this planetary gear mechanism, and the outer periphery of the internal gear 66 will have a plurality of grooves 66a for preventing rotation formed at predetermined intervals. The same convex portion 67e (refer to FIG. 8) of the spacer 67 is externally attached to the internal gear 66 'so that the output shaft 63d protrudes from the opening 6 7b of the spacer 67, and the outer periphery of the tolerance ring 62 is projected. It fits into the connection hole 40a provided in the rear end of the rotating shaft 40, and completes assembly of the planetary gear set B. However, a ring-shaped magnet 61 (two N-S is formed) is integrated in advance on the flange 40b of the rotary shaft 40 using a buckle or the like. Further, a protection block 67c for protecting an area detection circuit 71 described later is provided on the deep side of the spacer 67, and a wiring processing rib 67d is provided on the surface of 67c. Next, a procedure for assembling the automatic opening and closing device 30 will be described with reference to Figs. Self-tapping bolts (not shown) are inserted into the mounting holes 70b of the rotation detection circuit 70 of the Hall IC 70a that detects the magnetic force of the magnet 34c, and the bolts are fixed to the lower holes 31e of the mounting hub provided in the housing 31a. The casing 3 1 a and the rotation detection circuit 70 are integrated. Next, a self-tapping bolt (not shown) is inserted into the mounting hole 7 1 c of the area detection circuit 7 1 of the Hall IC71 a, 7 1 b on which the magnetic force of the detection magnet 61 is mounted, and it is fixed to the housing provided with the bolt. The lower hole 31f of the mounting hub portion of 31a integrates the case 31a and the area detection circuit 71. However, in the area detection circuit 71, the current-carrying wiring (not shown) is welded to the drive motor 3, and further, a positive characteristic thermistor 7 1d connected in line with one of the line-driving wirings is further welded. This positive characteristic thermistor is provided to prevent current from flowing to the drive motor 3 2. Next, the drive motor assembly A is stored in the motor storage portion 3 1 c provided at the lower end portion -28 of the housing 3 1 a (25) (25) 200418425, and the self-tapping bolt (not shown) is inserted into the spacer. The mounting hole 3 3 f of the sheet 3 3 is fixed to the lower hole 3 1 d provided in the mounting hub portion of the housing 3 1 a by bolts to integrate the housing 3 1 a and the drive motor assembly A. Next, the planetary gear set B is aligned with the rib 3 1 r (refer to FIG. 28) provided in the cylindrical portion 3 1 g of the casing 3 1 a and the groove 67 a provided on the outer periphery of the spacer 67. The outer shape of the protective block 67c of the spacer 67 and the inner wall of the casing 31a are inserted into and fixed to the cylindrical portion 31g against each other. However, a through-hole 3 1 i is provided in the rear side wall of the cylindrical portion 3 1 g, and the peripheral wall 31 j of the through-hole 3 li and the O-ring 40 c accommodated in the O-ring groove 40 provided in the rotation shaft 40 are provided. Water is prevented from entering through the through hole 31i. Here, the reason for using the spacer 67 to mount the housing 31a is that the star gear mechanism itself needs to be perfectly round in function. If it is directly mounted to the housing 3 1 a, the cylindrical portion 3 1 g of the housing 3 1 a also needs to be installed. The roundness makes the dimensional tolerance strict and the yield deteriorates. Therefore, the manufacturing tolerances can be determined by the elasticity of the spacers 67 by making contact with the protrusions 31r of the mountain portions 67e of the spacer 67 and the shell 31a with a slight point. The deformation-absorbing structure makes it easy to manufacture the cylindrical portion 3 1 g of the casing 3 1 a. Next, while paying attention to the meshing of the planetary gear 64 and the sun gear 38b, while inserting the third gear 38 into the planetary gear mechanism, pay attention to the meshing of the small gear 37b and the large gear 38a and the meshing of the large gear 37a and the small gear 34b. The second gear is inserted into the fixed shaft 31k. Finally, the shaft hole 3 8c of the third gear 38 is inserted into the shaft 311 provided in the housing 31b, and at the same time, the tip of the shaft 31k is inserted into the bearing 31m -29- (26) (26) 200418425 to automatically tap Bolts are inserted into the mounting holes 3 1 η provided in the housing 3 1 a and screwed into the lower holes 31 ρ ′ provided in the mounting hub portion of the housing 31 b to complete the assembly of the automatic opening and closing device 30 for the toilet seat. As shown in FIG. 28, two circles (Ca, Cb) of the projection surface of the external shape of the drive motor 32 and the planetary gear mechanism are arranged adjacent to each other, and further, the two circles (Ca, Cb) and two circles The axis of the first gear 34 and the second gear 37 arranged on the projection plane surrounded by the external wiring (Lc'Ld) can design the automatic opening and closing device 30 to be lightweight. Further, in the present embodiment, the first gear 34 and the second gear are disposed in the horizontal plane (La, Lb) passing through the center of the two circles (Ca, Cb) and the projection plane surrounded by the outer wires (Lc, Ld). The shaft of the gear 37 can be further reduced in weight and can be designed. Instead of the horizontal lines (La, Lb), a line connecting the centers of two circles (Ca, Cb) may be a vertical line passing through the centers of the circles. In this embodiment, since this vertical line is also slightly horizontal, although there is no big difference, such a design in which the reduction gear train is arranged in the horizontal direction is preferable. Next, an automatic opening and closing device 130 for a toilet lid will be described. Since the automatic lid opening and closing device 130 for a toilet seat has the same component structure and assembly procedure as the automatic lid opening and closing device 30 for a toilet seat, the description thereof is cut apart from the following differences. The automatic opening / closing device 30 for a toilet seat and the automatic opening / closing device 130 for a toilet lid are symmetrical components. As shown in Fig. 22, Fig. 24 and Fig. 28, the output shaft 140 of the automatic opening and closing device 130 for the toilet cover is provided with a fixed rectangular connection hole -30- (27) that prevents the rotation shaft 50 from being inserted into a fixed position. (27) 200418425 141. Further, the outer casing 131a of the automatic lid opening / closing device 130 for the toilet lid is integrally formed with the side wall 1 1b of the outer casing 11 and the hub portion 1 3 1b for maintaining a predetermined interval and the receiving projection 131c of the cap member lid. Next, the auxiliary element 80 will be described using Figs. 23 and 29. The auxiliary element 80 is composed of a connection shaft 81 which is non-rotatably connected to the rotating shaft 40 of the automatic opening and closing device 30, and one end 82a is fixed to the connection shaft 81 in order to push the toilet seat 12 in the opening direction. The auxiliary spring 82 and the other end 82b of the auxiliary spring 82 while fixing the other end 82b of the auxiliary spring 82 in a non-rotatable connection with the cover 83, and the cover 84 surrounding the auxiliary spring 82 together with the connection cover 83, and from the toilet seat 1 2 The attachment / detachment operation lever 85 for attaching and detaching the casing 11 and the fixing member 86 for fixing the auxiliary element 80 to the toilet seat 12 are configured. The leading end portion 8 1 a of the connecting shaft 8 1 (the supporting shaft of the toilet lid 13) is formed with a serration, and a large-diameter portion 81 b for regulating movement in the thrust direction of the connecting shaft 81 is formed at a substantially central portion. Further, an O-ring groove 81c is formed between the seal and the inner cylindrical portion 84a of the cover 84, and an insertion hole for inserting one end of the auxiliary spring 82 between the large-diameter portion 81b and the O-ring groove 81c is formed. 81d. In addition, an O-ring groove 81e is formed between the seal and the inner cylindrical portion 8 3a of the cover 83, and a groove 81 having a shape substantially the same as the outer shape of the rotary shaft 40 is formed at the end portion. One end 82a of the auxiliary spring 82 is The insertion hole 81d is bent toward the center, and the other end 82b is a support groove 83b that is bent toward the center and fixed to the outer periphery of the inner tube portion 83a of the connection cover 83. However, the root portion of the supporting groove 83b is a plate 83d which prevents the auxiliary spring 8 2 -31-(28) (28) 200418425 from rotating at the other end 82b by increasing the thickness of the bottom portion 8 3 c slightly. And, at the rear end of the connecting cover 8 3, an engaging protrusion 3} formed integrally with the outer casing 3 of the automatic opening and closing device 3 0 for the toilet seat is formed. One of the peripheral portions of the protruding 8 3 e forms a stopper 8 3 f that regulates the rotation of the loading / unloading operation lever. In addition, a number of reduced diameter portions 8 3 h are formed in the outer tube portion 8 3 g. A rib 8 3 i for welding is formed at the open end of the connecting cover 8 3 over the entire periphery, and the cover 84 is integrated by ultrasonic welding or the like. The attaching and detaching operation lever 85 is formed by a support cylinder 85a cut off from above and a mounting cylinder 8 5 b cut off from below, and a plurality of annular ribs 8 5 c having an increased thickness inside and outside are formed therebetween. The inner diameter of this annular rib 8 5 c is slightly the same as the diameter of the small-diameter portion 83h and smaller than the diameter of the outer cylindrical portion 83g. In addition, a holding protrusion 85d is formed in the attaching and detaching cylinder 85b. The fixing member 86 is formed with a connection opening 8 6 a having a shape substantially the same as the external shape of the connection shaft 81, and protrusions 8 6 b provided at predetermined intervals along the outer periphery in order to be fixed to the toilet seat 12 in a rotatable manner. Character-shaped connecting crank 86c. Further, the connecting crank 86c is formed with a lower hole 86d for connecting bolts. The stopper 86e that regulates the movement in the thrust direction of the auxiliary element 80 (except for the fixing member 86) Next, referring to FIG. 29, the assembly procedure of the auxiliary element 80 will be described. The O-ring is accommodated in the O-ring grooves 81c and 81e 'of the connecting shaft 81. One end 82a of the auxiliary spring 82 is inserted into the insertion hole 81d' of the connecting shaft 81. The other end 82b is engaged with the supporting groove 83b of the connecting cover 83. The shaft 81 is inserted into the inner tube portion 8 3 a of the connecting cover 8 3 to the end portion of the inner tube portion 8 3 a -32- (29) (29) 200418425 The large diameter portion 8 1 b of the shaft 8 1 abuts So far. Thereby, the other end 82b of the auxiliary spring 82 is troughed into the prevention wall 83d. Next, 'the leading end portion 8a of the connecting shaft 8i is inserted into the inner cylindrical portion 84a of the cover 84' in a state where the back side of the cover 84 and the welding rib 83i of the connecting cover 83 are in contact with each other. The cover shaft 81, the auxiliary spring 82, the connection cover 83, and the cover 84 are integrated into a body by ultrasonic vibration of the cover. Next, although the attachment / detachment operation lever 85 is inserted into the outer cylindrical portion 83g, the outer cylindrical portion 8 3 g has a diameter larger than the annular rib 8 5 c. Therefore, the annular rib 8 5 c is the outer cylindrical portion 8 3 g. When the small diameter portion is lifted up to 8 h, the connection cover 83 and the attaching / detaching operation lever 85 are integrated, and the attaching / detaching operation lever 85 is controlled by the outer cylinder portion 83g and the annular rib 85c to fall off in the thrust direction. Subsequently, the auxiliary shaft 80 is integrated into the connecting opening 81a of the fixing member 86 by inserting the connecting shaft 81. The connecting shaft 81 of this auxiliary element 80 is inserted into the connecting hole 12d (refer to FIG. 21) of the toilet seat 12, and the auxiliary member 80 is inserted into the connecting portion 12a of the toilet seat 12. The lower hole 86d and the bolt hole 12c of the toilet seat 12 (refer to FIG. 21) are formed by self-tapping bolts to unite the component 80 assisted by the toilet seat 12. However, the connecting crank 86c can be elastically deformed to the outside before being mounted on the toilet seat 12. Therefore, although the auxiliary member 80 (except the fixing member 86) can be detached from the fixing member 86, it is installed on the toilet seat 1. 2 is followed by the toilet seat 12 to regulate the deformation on the outside. Therefore, the flange 83j of the cover 83 connected to the stopper 86e and the auxiliary element 80 (except for the fixing member 8 6) are regulated in the thrust direction. -33- (30) (30) 200418425 Also, the loading / unloading operation lever 85 also reduces the clearance connecting the crank 86c and the outer cylinder portion 83g and can pass the outer cylinder portion 83g to the extent that the loading / unloading operation lever 85 does not deform outward. To prevent falling off in the thrust direction. Next, the tolerance ring 62 will be explained using the schematic diagram shown in FIG. The tolerance ring 62 has a ring shape having a wave-shaped portion as shown in Fig. 30. Each wave acts as a spring, and the acting force is proportional to the amount of deformation of the wave. The force required during assembly is AF, the radial force is RL (N), the friction coefficient is //, the wave number is η, the wave deformation is c (mm), and the spring coefficient is K (N / mm). If the torque is Mt and the shaft diameter is d (m), it can be calculated by RL = n · c · K AF = RL · β Mt = AF · d / 2. The spring coefficient can be set by changing the thickness, wave spacing, width, shape, and height of the material. Under normal conditions, the maximum torque at the time of rotating the shafts 40 and 140 is obtained by experiments. The shape of the tolerance ring 62 is selected based on the torque. 〇When the torque above the set torque occurs in the rotating shaft 40, the wave-shaped portion 62a of the tolerance ring 62 is fixed by being fitted into the connecting hole of the rotating shafts 40 and 140, and the annular edge portion 62b of the tolerance ring is sliding. On the outer periphery of the output shaft 63d of the carrier 63, an excessive weight exceeding the set torque is not applied to the automatic opening and closing devices 30 and 130, and gear damage can be prevented. -34- (31) (31) 200418425 As shown in Figure 31 As shown, the shaft of the drive motor 32 passes through the inside of the motor, and its diameter is relatively thick inside, and the exposed portion is formed with a small diameter. The diameter of this tip portion 3 2 a is set to reduce the number of teeth of the gear 3 2 b as much as possible to increase the reduction ratio. However, although the shaft itself can be reduced in diameter, if the shaft is thin, the shaft vibration of the drive motor 32 will increase if the shaft is thin. Therefore, the shaft itself cannot be reduced in diameter, and only the pinion 32b can be installed. Part of the diameter. Next, a description will be given of an operation caused by the above configuration. Fig. 32 is a control block diagram of the toilet seat device of the present invention. If the human body detection detector detects or operates a toilet lid opening switch (not shown) provided on a remote control or the like, the drive motor 3 2 in the automatic opening / closing device 130 for the toilet lid is energized, and the drive motor 32 rotates. Is transmitted to the rotating shaft 50 through the reduction gear train (gear 32b, the first gear 34, the second gear 37, the third gear 38, the star gear mechanism), the tolerance ring 62, and the output shaft 140, and the toilet lid is opened 1 3 . However, the magnet cover 61 and the two Hall ICs 7 1 a and 7 1 b provided in the area detection circuit 7 1 detect the toilet lid 13 and are located in the closed area (less than 20 degrees) and the rotating area (20 degrees). ~ 80 degrees), open area (80 degrees to 110 degrees), abnormal area (110 degrees or more), the energization control (or short-circuit control) of the drive motor 32 corresponding to each area is performed. Further, the Hall IC 700a provided in the magnet 34c and the rotation detection circuit 70 can detect the rotation of the drive motor 32 to more accurately detect the position within the area ', and can perform detailed energization control. In addition, when the toilet seat opening switch provided in the remote control is operated, the toilet seat -35- (32) (32) 200418425 is powered by the drive motor 3 2 in the automatic opening and closing device 30 and passes through the reduction gear train (pinion gear) 32b, the first gear 34, the second gear 37, the third gear 38, the star gear mechanism) and the tolerance ring 62 transmit the rotation of the drive motor 32 to the rotation shaft 40, and open the toilet seat 12. However, similar to the automatic opening / closing device 130 for toilet lids, the position of the toilet seat 12 is detected by the rotation detection circuit 70 and the area detection circuit 71, and the energization control (or short circuit) of the drive motor 3 2 corresponding to the position is performed. (Control) ° The inside of the toilet seat 12 is heavy because it is provided with a heater for a greenhouse. Only the automatic opening and closing device 30 for the toilet seat has the same structure as the automatic opening and closing device for the toilet lid 30, because the toilet seat cannot be replaced. 1 2 is lifted, so the auxiliary element 80 is provided. This auxiliary component 80 is a built-in auxiliary spring 82 which is integrated with the housing 11 at one end and integrated with the toilet seat 12 at the other end. This auxiliary spring 82 is naturally long when the toilet seat 12 is slightly vertical, and becomes a twisted state when the toilet seat 12 is closed. Therefore, when the toilet seat 12 is closed, a torque on the open side can be generated, so that the toilet seat 12 can be lifted even with a structure that is slightly the same as the automatic opening and closing device 130 for the toilet lid. However, one end 82a of the auxiliary spring 82 is integrated with the housing 11 by engaging the regulation protrusions 8 3 e of the housing 83 and the engagement protrusions 31 q of the automatic opening and closing device 3 0 for the toilet seat mounted on the housing 11. The other end 82 b of the auxiliary spring 82 is integrated with the toilet seat 12 through the connecting shaft 81 and the fixing member 86. -36- (33) (33) 200418425 when the toilet seat off switch (not shown) is installed on the remote control, etc., the current opposite to the opening action will be applied to the drive motor 3 2 according to the rotation detection circuit 70 and The position of the toilet seat 12 detected by the area detection circuit 71 performs power-on control (or short-circuit control). The distance detection by the human body detection detector (not shown) or the operation of a toilet lid closing switch (not shown) provided on a remote control or the like will cause the toilet lid to open and close in the same way as the toilet seat 1 2 3〇 is controlled, the toilet lid 1 3 can be closed. (Industrial application possibilities) ® As described above, the automatic opening and closing device of the toilet seat or the toilet lid of the present invention can be used for the automatic opening and closing device of the toilet seat or the toilet lid of the western-style toilet. Since the installation area of the device can be reduced, and other functional parts can be provided under the toilet seat or the rotating shaft of the toilet cover, it is very useful when the toilet seat is washed with warm water that requires light weight and miniaturization. effective.
