200417669 ⑴ 玖、發明說明 【發明所屬之技術領域】 本發明係有關一種新穎的轉盤式制動栓鎖。 【先前技術】 圓筒銷子栓鎖雖具有各種型式，惟本申請人的主力產 品係被認爲具有較高安全性的圓筒銷子栓鎖中之制栓桿鎖 〇 該制栓桿鎖係如第1圖及第2圖所示，具備有：沿著 內周面的母線形成凸輪溝1的外筒2 ;設置以旋轉自如的 方式嵌合於該外筒，並介以間隙積層於中心線軸線方向的 複數片分隔板3、3，並且沿著中心軸線貫通鑰匙孔4的 內筒5 ;沿著該內筒5的母線延伸，在內筒的外周部上以 可移動方式導引至半徑方向，並彈壓在與上述凸輪溝1扣 合的外側緣突出於外側的方向之鎖桿6。 又，在分隔板之間的各間隙7插設有制栓桿1 1，該 制栓桿鎖係全體形狀大致爲C字形且以搖動自如的方式軸 撐一端部，並彈壓在與插入鑰匙孔的鑰匙之側端緣干涉的 方向，且在常態下，將內筒扣止在貫通軸線方向的支持銷 8，且，在自由端部外側端緣上形成用以收容鎖桿6的內 側緣之開鎖缺口 9。 繼而，上述的制動栓群分別與插通於鑰匙孔的鑰匙 (Opponent key)對應的鑰匙溝扣合時，以與鎖桿6的內側 緣整合（未圖示）的方式構成有各制栓桿1 1的開鎖缺口 9 ° -5- (2) (2)200417669 因而，將鑰匙插入至鑰匙孔4使內筒5在外筒2內相 對性轉動時，因在凸輪溝1與鎖桿6之間產生的楔作用， 可能使鎖桿6向內筒中心軸方向移動，換言之，圓筒銷子 栓鎖成爲開鎖狀態，內筒5轉動至開鎖方向。 此外，在一般的制栓桿鎖中，介以第3圖所示的第1 止動器15以及與第1止動器15呈面對稱的第2止動器（ 未圖示），一體結合裝設複數片的分隔板3,3、鑰匙導套 12及尾件13的尾栓塞14(參照第1圖），以構成內筒5。 亦即，止動器1 5係構成圓筒的一部份，在前端形成 防止脫落的突緣1 6，並且在沿著其母線形成複數個縱長 的矩形之收容孔17,17的板狀體上，除了最接近及離突緣 1 6最遠的收容孔1 7之外，在各收容孔1 7上插入形成於 分隔板的外周部之插入片1 8 (參照第4圖），並且與相反側 的未圖75第2止動器同時一體結合於複數片分隔板3,3。 繼而，在最接近突緣1 6的收容孔1 7插入與形成於鑰 匙導套12的外周面之上述插入片18相同的插入片（未圖 示），同樣地，藉由在止動器15的內端（第3圖的右端）裝 設尾柱塞14(參照第1圖），使以此方法構成的內筒與外筒 2嵌合，以不分解內筒5的方式包持。 此外，在內筒5的內端裝設具有與止動器i 5的突緣 1 6相同的防止脫落功能的蛇眼狀擋板1 9，以止輪2 1加以 固定。 另外，在第4圖中，符號22爲形成於各分隔板的鎖 桿6用的導引溝。 (3) (3)200417669 【發明內容】 以如上所述方法構成的制栓桿鎖當然可發揮所期望的 功能，尤其是鎖桿6在內筒轉動時呈現的插銷感’因此使 用感優良，又，因爲難以撬開’多使用作爲住宅大門的鎖 然而，一方面因爲制栓鎖1 1的形狀爲大致c字形’ 因此剛性較小，在以強力轉動不同的鑰匙時將產生變形。 又，插入鑰匙的鑰匙孔內之本體部（以下稱爲鑰匙板 孔）的側端緣形成鑰匙溝’因此無法使鑰匙溝的形成處所 增多，因而不同鑰匙的數量亦有限。 再者，因爲鑰匙的剖面形狀爲上下不對稱’故與鑰匙 板孔的表裡無關，無法製作出可插入至鑰匙孔的所謂可逆 鑰匙等上有改良的空間。 因此，本發明之目的在於提供一種制動栓的剛性大之 可逆的鑰匙，且具有不同的鑰匙之相當新穎的轉盤式制動 栓鎖及其鑰匙。 〔用以解決課題之方案〕 爲達成上述目的，申請專利範圍第1項之轉盤式制動 栓鎖，其特徵在於具備有：沿著內周面的母線形成凸輪溝 之外筒；以旋轉自如的方式嵌合於該外筒並設置介以間隙 積層於中心軸線方向的複數片分隔板，並沿著中心軸線貫 通鑰匙孔之內筒；以及沿著該內筒的母線延伸’在內筒的 外周部上以可移動方式導引至半徑方向，並使與上述凸輪 -7- (4) (4)200417669 溝扣合之外側緣彈壓在突出於外側的方向上之鎖桿，在上 述分隔板之間的各間隙插設有在中央部形成可包圍鑰匙孔 的大小之鑰匙插通孔的環狀之轉盤式制動栓，該轉盤式制 動栓之實體部的一處，以可搖動方式軸承於使內筒貫通於 軸線方向的支軸，並在自由端部外側端緣形成開鎖缺口， 一方面在鑰匙插通孔的開口端緣上一體突設有前端的移動 軌跡與插入鑰匙孔的鑰匙之鑰匙孔板的平面部或端緣部干 涉的扣合突起，並將各轉盤式制動栓彈壓在該扣合突起接 近鑰匙的方向，且在常態下使內筒扣合在貫通軸線方向之 支持銷，另一方面在與上述的制動栓群之扣合突起與插入 至鑰匙孔的鑰匙之鑰匙孔板所形成之對應凹處扣合時，使 各轉盤式制動栓的開鎖缺口與鎖桿的內側緣整合。 又，申請專利範圍第2項之轉盤式制動栓鎖及鑰匙， 其特徵在於具備有：沿著內周面的母線形成凸輪溝之外筒 ;以旋轉自如的方式嵌合於該外筒並設置介以間隙積層於 中心軸線方向的複數片分隔板，並沿著中心軸線貫通鑰匙 孔之內筒；以及沿著該內筒的母線延伸，在內筒的外周部 上以可移動方式導引至半徑方向，並使與上述凸輪溝扣合 之外側緣彈壓在突出於外側的方向上之鎖桿，在上述分隔 板之間的各間隙插設有在中央部形成可包圍鑰匙孔的大小 之鑰匙插通孔的環狀之轉盤式制動栓，該轉盤式制動栓之 實體部的一處，以可搖動方式軸承於使內筒貫通於軸線方 向的支軸，並在自由端部外側端緣形成開鎖缺口，一方面 在鑰匙插通孔的開口端緣上一體突設有前端的移動軌跡與 -8 - (5) (5)200417669 插入鑰匙孔的鑰匙之鑰匙孔板的平面部或端緣部干涉的扣 合突起5並將各轉盤式制動检？早壓在s亥扣合突起接近繪匙 的方向，且在常態下使內筒扣合在貫通軸線方向之支持銷 ，另一方面在與上述的制動栓群之扣合突起與插入至鑰匙 孔的鑰匙之鑰匙孔板所形成之對應凹處扣合時，使各轉盤 式制動栓的開鎖缺口與鎖桿的內側緣整合之轉盤式制動栓 鎖，在插入鑰匙孔時，在與各轉盤式制動栓的扣合突起之 前端整合的鑰匙孔板之部位上，形成有底且具有固定深度 的摺缽形的凹處，與該凹處所對應的扣合突起扣合時，使 各轉盤式制動栓的開鎖缺口與鎖桿的內側緣整合。 【實施方式】 以下，參照第5圖至第12圖說明本發明。 第1圖至第4圖所示的習知之制栓桿鎖與本發明的轉 盤式制動栓鎖最大的不同點有兩處：制動栓的形狀爲環狀 、以及取代鑰匙孔板之側端緣的鑰匙溝而在鑰匙的平面部 及端緣部形成凹處。 亦即，第5圖係顯示本發明一實施例的轉盤式制動式 栓鎖的間隙7，該間隙7係如習知的制栓桿鎖般，藉由附 有突緣1 6的止動器1 5形成於相互結合之複數片分隔板3 、3之間。 又，以將沿著中心軸線形成的鑰匙孔4夾持於中間， 在第5圖上方設有支軸23且在下方分別使內筒5與鑰匙 孔平行貫通的方式設有支持銷8(參照第1圖）。 (6) (6)200417669 此外，第5圖所示的支持銷8的剖面形狀雖與第1圖 所示者不同，係將縱長的矩形之上隅部去角的形狀，惟該 支持銷8的形狀並非本發明的主旨，亦可以是第1圖所示 的圓棒狀。 又，如第5圖所示的剖面形狀之鑰匙孔4雖插入具有 相同剖面形狀的鑰匙24，惟上述鑰匙孔4或鑰匙24的剖 面形狀並非本發明的主旨。 在圖式的實施例中如圖式所示，鑰匙孔4的橫剖面形 狀較複雜之原因除了使所謂的障礙突起之種類增多，使不 同鑰匙增多的目的之外，使難以在鑰匙孔4內操作撬鎖工 具 ° 又，鑰匙孔4(鑰匙24)的剖面形狀與內筒5的中心軸 線有關設成點對稱之原因與鑰匙的表裡無關之可將鑰匙插 入鑰匙孔4的所謂可逆鑰匙。 繼而，在本發明之轉盤式制動栓鎖進行開鎖操作所使 用的鑰匙24，係如第6圖及第7圖所示，插入至鑰匙孔4 的本體部（以下簡稱爲鑰匙孔板）之前端係成形於圓弧上並 且進行去角，同時在第6圖所示的平面部、及第7圖所示 的端緣部之特定地方形成有凹處2 5。 該凹處2 5的剖面形狀係例如第5圖所示，爲使圖面 容易明白，在未剖視的鑰匙24之剖面形狀上以點線表示 ’又’如第6圖及第7圖所示，凹處25係有底的逆台形 ，且具有複數種深度（圖示的實施例中爲4種）。 就上述凹處2 5的形成位置及深度而言，與後述的轉 -10- (7) (7)200417669 盤式制動栓之關連如後所述。 另外，週知在第1圖及第2圖所示的習知之制栓桿鎖 、盤狀制動栓鎖、或是銷狀制動栓鎖中，在鑰匙孔板的側 端緣形成有V字形的鑰匙溝，沒有形成凹處。 此外，由於在第5圖中附加與第1圖及第2圖相等的 符號之部分係表示相同的部分，因此省略詳細說明。 再者，如第8圖所示，在上述間隙7,7中插設有在中 央部形成可包圍鑰匙孔4的大小之鑰匙插通孔26之環狀 的轉盤式制動栓2 7。 在此，轉盤式制動栓27爲環狀的意思在於包圍鑰匙 插通孔26的轉盤式制動栓27的實體部係構成封閉曲線之 意，轉盤式制動栓27的外形係如圖示大致爲圓形。 各轉盤式制動栓27係藉由支軸22以可搖動方式軸承 於其實體部之一處（在圖示的實施例之上端部）。 繼而，轉盤式制動栓27的自由端部（第8圖的下端部 )之內側緣及外側緣的雙方亦形成以支軸2 2爲中心之圓弧 狀。 又，轉盤式制動栓27的自由端部外側緣的特定角度 位置例如形成有矩形的開鎖缺口 9。 該開鎖缺口 9的形成角度位置係因應上述鑰匙的凹處 25的深度例如有4種，藉此獲得轉盤式制動栓鎖的不同 鑰匙。 再者，轉盤式制動栓2 7的自由端部內側緣以掠過支 持銷8的下端之方式形成，其第8圖的左端部形成有扣止 -11 - (8) (8)200417669 段部2 8。 . 此外，該扣止段部2 8不僅爲段部當然亦可爲突起。 另外，在鑰匙插通孔2 6的開口端緣上一體突設有如 第8圖所示，前端的移動軌跡與鑰匙24的鑰匙孔板之平 面部干涉的扣合突起2 9。 ' 又，該扣合突起2 9係如第9圖所示，亦有以前端的 移動軌跡與鑰匙孔板的端緣部干涉的方式，偏離突設位置 而突設之情況。 肇 然後，各轉盤式制動栓27係與習知的制栓桿鎖相同 ，藉由薄的板彈簧之制動栓彈簧3 1的彈力，使該扣合突 起29彈壓於接近鑰匙24的方向。 如弟8圖及弟9圖所不’在繪匙孔4未插入論匙24 時，以使各轉盤式制動栓2 7的上述扣止段部2 8彈接於支 持銷8的方式扣止，各轉盤式制動栓27係扣止於第8圖 及第9圖所τκ的角度位置。 然而，在鑰匙孔4插入鑰匙24，扣入在各轉盤式制 ® 動栓27的扣合突起29所對應的鑰匙之凹處25時，如第 1〇圖及第1 1圖所示，以全部的轉盤式制動栓27,27的開 鎖缺口 9,9與鎖桿6內側緣整合之方式，設定扣合突起2 9 的突出量、凹處2 5的深度及開鎖缺口 9的角度位置。 在圖示的實施例中，將扣合突起29的突出量設爲一 定，換言之，與支軸23的中心有關，將扣合突起29的前 端位置設爲固定，當扣合突起29的前端扣入鑰匙的凹處 2 5並抵接於其底面時，因應凹處2 5的深度使轉盤式制動 -12- 200417669 Ο) 栓2 7的搖動角度變化，俾使第8圖所示的複數個開鎖缺 - 口 9,9內已選擇者與鎖桿6的內側緣整合。 此外，即使在本發明的轉盤式制動栓鎖中’與習知的 制栓桿鎖相同，彼此鄰接的轉盤式制動栓27係以左右對 ^ 稱的方式配設有扣合突起29較佳。 ' 這是因爲使扣入有扣合突起的鑰匙之凹處2 5,25彼此 的間隔變長，尤其是凹處較深時，不干涉相鄰接的凹處之 緣故。 籲 如上述方法所構成的本發明一實施例的轉盤式制動栓 鎖，在鑰匙24未插入至鑰匙孔4時，或是在鑰匙孔4插 入與鑰匙不同的鑰匙時，至少一片的轉盤式制動栓27之 開鎖缺口 9與鎖桿6的內側緣產生角度性的偏離（參照第 8圖及第9圖）。 在該狀態下轉動內筒5時，雖欲藉由鎖桿6與凸輪1 之間產生的楔作用使鎖桿6從凸輪溝1押出，惟其動作被 轉盤式制動栓27的自由端部外側緣阻止而無法轉動內筒 ® 5。亦即，無法轉開該轉盤式制動栓鎖。 另外，在鑰匙孔4插入有鑰匙24時，如上所述，又 ，如第1 〇圖及第1 1圖所示，使全部的轉盤式制動栓2 7 之開鎖缺口 9，9與鎖桿的內側緣整合。 在該狀態下轉動內筒時，與習知的制栓桿鎖相同，因 爲內筒5與外筒2之相互轉動而可移動鎖桿6的內筒中心 軸線方向，進而轉開該轉盤式制動栓鎖。 此外’在鑰匙孔插入鑰匙以及不同的鑰匙時，沒有鑰 -13 - (10) (10)200417669 匙孔板的凹處之部分與扣合突起29扣合，即使扣合突起 _ 29從鑰匙孔4退避時，如第12圖所示，以鑰匙插通孔26 不與鑰匙孔4干涉的方式，設定其大小及開口位置。 又，在第8圖及第9圖所示之進行栓鎖的狀態，由於 = 使內筒轉動之力作用於將鎖桿6推昇至上方的方向，因此 、 使轉盤式制動栓27與支持銷8之間的摩擦消失，使前者 的搖動變爲圓滑，如圖所示，在兩者之間設置間隙時，該 力係坦持於支軸2 3。 _ 這不是因爲作動上的問題，惟欲分散其力以坦持支持 銷8時，所選擇或將與全部的轉盤式制動栓27之支軸嵌 合的支軸孔設爲例如上下長形的長孔亦可。 此時，當轉盤式制動栓2 7承受來自鎖桿6的力，使 轉盤式制動栓27之移動至上方的結果，其自由端部與支 持銷8抵接，使負載坦持於支持銷。 此外，本發明係不需限定於圖示的實施例，可進行種 種的變形。 鲁 例如，在以上的說明中，將進入第9圖及第1 1圖所 示的鑰匙孔板的端緣部之凹處25的轉盤式制動栓27使用 於與進入鑰匙孔板的平面部之凹處相同者，惟由於鑰匙孔 板的端緣較薄而凹處深度的種類僅採用兩種，因此亦可容 易按圖索驥地將此應用在其他用途上。 亦即，例如在公寓的大門口設計僅具有進入第7圖所 示的鑰匙孔板之端緣部所形成的凹處25,25之轉盤式制動 栓2 7,27的轉盤式制動栓鎖，共同組裝進入上述鑰匙孔板 -14- (11) (11)200417669 的端緣部所形成的凹處之制動栓，以進入鑰匙孔板的平面 部之凹處的不同制動栓作爲不同的鑰匙，成爲居住者用的 鎖。 於是，各居住者可以一隻鑰匙打開自己的房子和共同 大門的鎖，可構成所謂反萬能鑰匙裝置。 此時，由於在用於反萬能鑰匙裝置時不需從鑰匙孔板 的平面部使制動栓疏離分布，因此換言之，與平面部所形 成的凹處相對之轉盤式制動栓鎖全部用於居住者用的不同 鑰匙，因此使居住者用的不同鑰匙大幅增加。 相對於此，習知的栓鎖例如制栓桿鎖或盤狀制動栓鎖 雖亦可構成反萬能鑰匙裝置，惟在習知的栓鎖中，將應該 用於不同的鑰匙之制動栓轉換爲應用於反萬能鑰匙裝置， 因此使居住者用的不同鑰匙減少。 又，在以上的說明中，雖可將轉盤式制動栓27的扣 合突起29之突起量設爲固定，且因應鑰匙的凹處之深度 改變制動栓的搖動角度，惟因應凹處2 5的深度改變扣合 突起29的突出量亦可。 此時，例如當凹處25較深時，若加大扣合突起29的 突出量，即使改變凹處的深度亦可使制動栓的搖動角度相 同，因此即使將開鎖缺口 9 (參照第8圖）的角度位置設爲 相同，亦可獲得與圖示實施例的轉盤式制動栓鎖相同數目 的不同鑰匙。 第1 3圖係顯示申請專利範圍第1項所記載的發明之 其他實施例，該實施例係使支軸23的位置移動至離開內 -15- (12) (12)200417669 筒中心軸之方向，利用該支軸2 3與鎖桿6之間的距離使 鍮匙24的剖面形狀較長的一方可垂直插入鑰匙孔4，換 言之，使鑰匙形成所謂的縱差者。 此外，在第1 3圖中，附加與其他圖相等的符號之部 分表示相同的部分。 藉由上述方法形成之構成，不僅可使栓鎖的種類倍增 ，可因應顧客的喜好選擇具人體工學且操作容易的栓鎖。 又，由於支軸23與開鎖缺口 9之距離增大，因此若 使扣合突起29的形成位置移動至接近支軸23的方向，即 使凹處2 5的深度僅產生些微的變化，亦可加大開鎖缺口 9的移動距離，具有可提昇鑰匙的識別感度之優點。 第1 4圖係表示申請專利範圍第3項所記載的發明之 一實施例的轉盤式制動栓鎖，該實施例係在支軸23與支 持銷8的相反側設置與其平行的彈簧支軸3 2，藉由作爲 扭轉線圈彈簧使用的制動栓彈簧3 1彈壓各轉盤式制動栓 27 ° 此時，各制動栓彈簧3 1的線圏部以卷裝於支軸3 2的 方式，使與該線圈部連接的開腳彈簧的前端彼此彎折於相 反方向，並且彎折於紙面方向，而可將制動栓彈簧3 1收 容在狹窄的間隙7內。 以制動栓彈簧3 1作爲扭轉線圏彈簧，並在其線圏部 插通彈簧支軸3 2，與習知的制動栓彈簧3 1 (第8圖及第9 圖）將細長的彈簧板之一端變圓且嵌入與轉盤式制動栓27 相同形狀的孔中之裝設方法比較，可防止制動栓彈簧脫離 -16- (13) (13)200417669 及轉盤式制動栓鎖之作動不良。 〔發明之功效〕 如以上說明可淸楚得知，由於本發明係將制動栓的形 狀設爲環狀，因此與習知的制栓桿比較，特別可提昇制動 栓的剛性，可提升栓鎖的強度及安全性。 又，由於與習知的制栓桿鎖之鑰匙不同，不僅藉由鑰 匙孔板的端緣部所形成的V字形鑰匙溝，亦可藉由凹處 的深度獲得不同的鑰匙，因此與一個凹處25鄰接的其他 凹處25之間隔可設置成短於習知的鑰匙溝。 換言之，在外型尺寸上有規格的限制之內筒中，可增 加制動栓的數量，亦可使不同的鑰匙增加。例如，在習知 的制栓桿鎖最多雖可放入7片的制動栓，惟在本發明之轉 盤式制動栓鎖中可放入1 1片（參照第6圖）。 再者，不僅在鑰匙孔板的平面部亦可在端緣部形成凹 處，利用在該端緣部的凹處構成機械性的公共大門之反萬 能鑰匙裝置，可使居住者用的不同鑰匙比習知多。 又，由於即使轉盤式制動栓鎖的扣合突起之突出量設 爲固定或變化時，因應凹處的深度使其中心位置在鑰匙孔 板的寬度方向或鑰匙孔板的端緣部之寬度方向上必須產生 微妙的變化，因此使鑰匙的複製變爲困難’可達到提昇栓 鎖的安全性等種種的功效。 【圖式簡要說明】 -17- (14) (14)200417669 第1圖係習知的制栓桿鎖的一例之縱剖面圖。 . 第2圖係其橫剖面圖。 第3圖係止動器的外觀斜視圖。 第4圖係分隔板的正面圖。 第5圖係在本發明一實施例之轉盤式制動栓鎖的縱剖 ~ 面圖使制動栓脫離的狀態圖。 第6圖係本發明一實施例之轉盤式制動栓鎖的鑰匙之 平面圖。 ® 第7圖係本發明一實施例之轉盤式制動栓鎖的鑰匙之 側面圖。 第8圖係在本發明一實施例之轉盤式制動栓鎖的橫剖 面圖，裝設設置有與鑰匙的鑰匙孔板之平面部抵接的扣合 突起之制動栓之狀態圖。 第9圖係在本發明一實施例之轉盤式制動栓鎖的橫剖 面圖，裝設設置有與鑰匙的鑰匙孔板之平面部抵接的扣合 突起之制動栓之狀態圖。 1 第1 0圖係與第8圖相同的轉盤式制動栓鎖的橫剖面 圖，在鑰匙孔上插入有鑰匙的狀態。 第1 1圖係與第9圖相同的轉盤式制動栓鎖的橫剖面 圖，在鑰匙孔上插入有鑰匙的狀態。 第1 2圖係與第8圖相同的轉盤式制動栓鎖的橫剖面 圖，在鑰匙孔上插入有鑰匙，且扣合突起的前端搭載於鑰 匙孔板的表面之狀態。 第1 3圖係申請專利範圍第1項所記載之發明的其他 -18- (15) (15)200417669 實施例之轉盤式制動栓鎖與第8圖相同的橫剖面圖。 _ 第1 4圖係申請專利範圍第3項所記載之發明的其他 實施例之轉盤式制動栓鎖與第8圖相同的橫剖面圖。 元件符號說明 _ 1 凸輪溝 2 外筒 3 分隔板 0 4 鑰匙孔 5 內筒 6 鎖桿 7 間隙 8 支持銷 9 開鎖缺口 11 制栓桿 12鑰匙導套 ® 14 尾柱塞 15 止動器 16 突緣 17 收容孔 1 8 插入片 19 擋板 2 1 止輪 22 導引溝 Λ -19- (16) (16)200417669 2 3 支軸 24 鑰匙 25 凹處 26 鑰匙插通孔 Λ 27 轉盤式制動栓 一 2 8 扣止段部 2 9 扣合突起 3 1制動栓彈簧 · 32 彈簧支軸200417669 ⑴ 玖, description of the invention [Technical field to which the invention belongs] The present invention relates to a novel turntable brake lock. [Prior art] Although the cylinder pin latch has various types, the main product of the applicant is a bolt lock in the cylinder pin latch which is considered to have high security. The bolt lock As shown in FIG. 1 and FIG. 2, it includes an outer cylinder 2 that forms a cam groove 1 along a generatrical line of an inner peripheral surface, and is provided with a rotatable fitting to the outer cylinder, and is laminated on a gap through the gap. A plurality of partition plates 3, 3 in the direction of the center line axis, which pass through the inner tube 5 of the key hole 4 along the center axis; extend along the generatrix of the inner tube 5 and are movably guided on the outer periphery of the inner tube. The locking lever 6 is guided to the radial direction and is pressed in a direction in which the outer edge engaged with the cam groove 1 protrudes outward. In addition, a bolt-making lever 11 is inserted into each of the gaps 7 between the partition plates. The entire shape of the bolt-locking system is approximately C-shaped, and one end of the shaft is supported in a swingable manner, and is pressed against and inserted into the key. The direction in which the side edge of the key of the hole interferes, and in a normal state, the inner cylinder is fastened to the support pin 8 in the direction of the through axis, and an inner edge for receiving the lock lever 6 is formed on the outer edge of the free end Unlocking gap 9. Then, when the above-mentioned brake bolt group is respectively engaged with a key groove corresponding to a key inserted in a keyhole (Opponent key), each bolt lever is configured to be integrated with the inner edge of the lock lever 6 (not shown). 1 1 unlocking notch 9 ° -5- (2) (2) 200417669 Therefore, when the key is inserted into the key hole 4 and the inner cylinder 5 is relatively rotated in the outer cylinder 2, the gap is between the cam groove 1 and the lock lever 6. The generated wedge action may cause the lock lever 6 to move in the direction of the central axis of the inner cylinder, in other words, the cylinder pin is locked to an unlocked state, and the inner cylinder 5 is rotated to the unlocking direction. In addition, in a general tumbler lock, a first stopper 15 shown in FIG. 3 and a second stopper (not shown) symmetrical to the first stopper 15 are integrated and integrated. A plurality of partition plates 3, 3, a key guide 12 and a tail plug 14 (see FIG. 1) of the tail piece 13 are installed to constitute the inner cylinder 5. That is, the stopper 15 is a part of a cylinder, and a flange 16 for preventing falling off is formed at the front end, and a plurality of longitudinally long rectangular receiving holes 17, 17 are formed along the generatrix. In addition to the receiving holes 17 closest to and farthest from the flange 16 on the body, an insertion piece 18 (see FIG. 4) formed on the outer peripheral portion of the partition plate is inserted into each of the receiving holes 17, And the second stopper (not shown in Fig. 75) on the opposite side is integrated with the plurality of partition plates 3, 3 at the same time. Then, the same insertion piece (not shown) as the above-mentioned insertion piece 18 formed on the outer peripheral surface of the key guide 12 is inserted into the accommodation hole 17 closest to the flange 16 and, similarly, by the stopper 15 A tail plunger 14 (refer to FIG. 1) is attached to the inner end (the right end in FIG. 3), and the inner tube configured in this way is fitted into the outer tube 2 and is held without disassembling the inner tube 5. In addition, a snake-eye baffle 19 having the same function of preventing the falling off as the flange 16 of the stopper i 5 is installed at the inner end of the inner cylinder 5 and fixed by a stop wheel 21. In Fig. 4, reference numeral 22 denotes a guide groove for a lock lever 6 formed in each partition plate. (3) (3) 200417669 [Summary of the invention] Of course, the bolt-locking lock configured as described above can certainly perform the desired function, and especially the latching feel of the locking rod 6 when the inner cylinder rotates, so the feeling of use is excellent, In addition, it is difficult to pry open a lock that is often used as a gate of a house. However, on the one hand, because the shape of the latch 11 is approximately c-shaped, the rigidity is small, and deformation occurs when a different key is turned with a strong force. In addition, the key grooves are formed at the side edges of the body portion (hereinafter referred to as the key plate hole) inserted into the key hole of the key, so that the number of different key grooves cannot be increased, and the number of different keys is also limited. Furthermore, because the cross-sectional shape of the key is asymmetrical up and down, it has nothing to do with the improvement of the so-called reversible key that can be inserted into the key hole, regardless of the front and back of the key plate hole. Therefore, the object of the present invention is to provide a reversible key with a large rigidity and a reversible key, and a relatively novel turntable type key with different keys and a key therefor. [Solution to Solve the Problem] In order to achieve the above-mentioned object, the rotary disc brake lock of the first scope of the patent application is characterized by having: a cam groove outer cylinder formed along a bus bar on the inner peripheral surface; A plurality of partition plates laminated in the direction of the central axis through a gap, and inserted through the inner cylinder of the keyhole along the central axis; and extending along the generatrix of the inner cylinder The outer peripheral part is guided to the radial direction in a movable manner, and the outer side edge of the groove engagement with the cam -7- (4) (4) 200417669 is elastically pressed against the lock lever protruding in the direction outward, and is separated in the above. Each gap between the plates is provided with a ring-shaped turntable brake bolt which forms a key insertion hole of a size that can surround the keyhole in the central portion. One of the solid parts of the turntable brake bolt is swingably supported. The inner cylinder penetrates the support shaft in the axial direction, and an unlocking gap is formed at the outer end edge of the free end. On the one hand, the front end movement track and the key inserted into the key hole are integrally provided on the opening end edge of the key insertion hole. Key The engaging protrusions interfering with the flat portion or the end edge of the orifice plate, and each turntable brake bolt is pressed in the direction in which the engaging protrusions approach the key, and the inner cylinder is engaged with the support pin in the direction of the axis under normal conditions. On the other hand, when the locking protrusions of the above-mentioned brake bolt group and the corresponding recesses formed by the keyhole plate of the key inserted into the keyhole are engaged, the unlocking notch of each turntable brake bolt and the inner edge of the lock lever Integration. In addition, the rotary disc brake lock and key of the second patent application range are characterized in that: a cam groove outer cylinder is formed along the generatrix of the inner peripheral surface; and the outer cylinder is fitted to the outer cylinder in a rotatable manner and provided. A plurality of partition plates laminated in the direction of the central axis through the gap and passed through the inner cylinder of the keyhole along the central axis; and extending along the generatrix of the inner cylinder and guided in a movable manner on the outer periphery of the inner cylinder A locking lever which is pushed to the radial direction and which engages the outer side edge of the cam groove in a direction protruding outward, is inserted into each gap between the partition plates, and is formed in a central portion so as to surround a keyhole. A ring-shaped turntable type brake plug with a key insertion hole, and a solid part of the turntable type brake pin is rotatably supported on a support shaft that allows the inner cylinder to penetrate in the axial direction, and is at the outer end of the free end. The edge forms an unlocking notch. On the one hand, the movement track of the front end and the flat part or end of the keyhole plate of the key inserted into the keyhole are integrally provided on the open end edge of the key insertion hole. Edge interference buckle Close the protrusion 5 and check each turntable brake? Press it early in the direction where the buckling protrusion is close to the drawing spoon, and in the normal state, the inner cylinder is buckled with the support pin in the direction of the through axis. On the other hand, the buckling protrusion with the above-mentioned brake bolt group is inserted into the keyhole. When the corresponding recess formed by the keyhole plate of the key is fastened, the turntable type brake lock which integrates the unlocking notch of each turntable type brake bolt with the inner edge of the lock lever is inserted into the keyhole. The bottom of the keyhole plate integrated at the front end of the locking protrusion of the brake bolt is formed with a bowl-shaped recess with a fixed depth. When the corresponding locking protrusion corresponding to the recess is engaged, each turntable is braked. The unlocking notch of the bolt is integrated with the inside edge of the lock lever. [Embodiment] Hereinafter, the present invention will be described with reference to Figs. 5 to 12. The most significant differences between the conventional lever lock shown in Figures 1 to 4 and the turntable brake lock of the present invention are two points: the shape of the brake pin is ring-shaped, and it replaces the side edge of the keyhole plate. The key groove is formed in a flat portion and an edge portion of the key. That is, FIG. 5 shows a gap 7 of a turntable brake lock of an embodiment of the present invention, and the gap 7 is like a conventional bolt lock, with a stopper attached with a flange 16 15 is formed between a plurality of partition plates 3, 3 combined with each other. In addition, a support pin 8 is provided so that the keyhole 4 formed along the center axis is sandwiched in the middle, a support shaft 23 is provided above FIG. 5, and the inner cylinder 5 and the keyhole are respectively penetrated below in parallel (see reference). Figure 1). (6) (6) 200417669 In addition, although the cross-sectional shape of the support pin 8 shown in FIG. 5 is different from that shown in FIG. 1, it is a shape in which the upper part of the longitudinal rectangle is chamfered, but the support pin 8 The shape of 8 is not the gist of the present invention, and may be a round rod shape as shown in FIG. 1. In addition, although a key hole 4 having a cross-sectional shape as shown in Fig. 5 is inserted with a key 24 having the same cross-sectional shape, the cross-sectional shape of the key hole 4 or the key 24 is not the gist of the present invention. In the illustrated embodiment, as shown in the figure, the reason why the cross-sectional shape of the keyhole 4 is complicated is that in addition to increasing the number of so-called obstacle protrusions and increasing the number of different keys, it is difficult to make it inside the keyhole 4 Operate the prying lock tool. Also, the cross-sectional shape of the key hole 4 (key 24) and the center axis of the inner cylinder 5 are set to be point-symmetric. The reason is that the key can be inserted into the key hole 4 regardless of the appearance of the key. Then, as shown in FIGS. 6 and 7, the key 24 used for unlocking the turntable brake lock of the present invention is inserted into the front end of the body portion of the keyhole 4 (hereinafter referred to as a keyhole plate). It is formed on a circular arc and chamfered, and at the same time, a recess 25 is formed in a specific portion of the flat portion shown in FIG. 6 and the edge portion shown in FIG. 7. The cross-sectional shape of the recess 25 is shown in, for example, FIG. 5. In order to make the drawing easier to understand, the cross-sectional shape of the uncut key 24 is indicated by a dotted line, as shown in FIGS. 6 and 7. It is shown that the recess 25 is a bottomed inverted platform and has a plurality of depths (four in the illustrated embodiment). As far as the formation position and depth of the above-mentioned recesses 25 are concerned, the relationship with the later-mentioned turn -10- (7) (7) 200417669 disc brake bolster is described later. In addition, it is well known that in the conventional bolt lock, disc brake lock, or pin brake lock shown in FIGS. 1 and 2, a V-shape is formed on the side edge of the keyhole plate. Key groove, no recess formed. It should be noted that the parts in FIG. 5 that are assigned the same reference numerals as those in FIGS. 1 and 2 represent the same parts, and detailed descriptions are omitted. Furthermore, as shown in Fig. 8, a ring-shaped disc brake bolt 27 is formed in the gaps 7, 7 in the center portion, and a ring-shaped disc brake bolt 27 having a key insertion hole 26 of a size that surrounds the key hole 4 is inserted. Here, the meaning that the rotary disc brake bolster 27 is ring-shaped means that the solid portion of the rotary disc brake bolus 27 surrounding the key insertion hole 26 forms a closed curve. The outer shape of the rotary disc brake bolus 27 is substantially circular as shown in the figure. shape. Each of the rotary disc brake bolsters 27 is rotatably supported at one of its solid portions (on the upper end of the illustrated embodiment) by a support shaft 22. Then, both the inner and outer edges of the free end portion (lower end portion in FIG. 8) of the disc brake bolster 27 are also formed in an arc shape with the support shaft 22 as a center. A rectangular unlocking notch 9 is formed at a specific angular position on the outer edge of the free end portion of the disc brake bolster 27, for example. The angular position of the unlocking notch 9 is, for example, four types depending on the depth of the recess 25 of the key, thereby obtaining different keys of the turntable type brake lock. In addition, the inner edge of the free end portion of the disc brake bolster 27 is formed so as to pass over the lower end of the support pin 8. The left end portion of FIG. 8 is formed with a buckle -11-(8) (8) 200417669 section. 2 8. In addition, the detent section 28 is not only a section but also a protrusion. In addition, as shown in Fig. 8, an opening end edge of the key insertion hole 26 is integrally provided with an engaging protrusion 29 that interferes with the flat surface of the key hole plate of the key 24. In addition, as shown in FIG. 9, the engaging projection 29 may be projected from the projected position by interfering with the movement trajectory of the front end and the edge of the keyhole plate. Then, each turntable brake pin 27 is the same as the conventional lock lever lock. With the spring force of the thin plate spring bolt spring 31, the engaging protrusion 29 is pressed in the direction close to the key 24. As shown in Fig. 8 and Fig. 9, when the keyhole 4 is not inserted into the key 24, it is locked in such a manner that the above-mentioned locking section 2 8 of each turntable brake bolt 27 is elastically connected to the support pin 8 Each turntable brake pin 27 is locked at an angular position τκ shown in FIG. 8 and FIG. 9. However, when inserting the key 24 into the keyhole 4 and snapping it into the recess 25 of the key corresponding to the engaging protrusion 29 of each turntable-type bolt 27, as shown in Fig. 10 and Fig. 11, The unlocking notches 9 and 9 of all the turntable brake bolts 27 and 27 are integrated with the inner edge of the lock lever 6 to set the protruding amount of the engaging protrusion 29, the depth of the recess 25, and the angular position of the unlocking notch 9. In the illustrated embodiment, the protruding amount of the engaging protrusion 29 is set to be constant, in other words, it is related to the center of the support shaft 23, and the front end position of the engaging protrusion 29 is fixed. When the recess 25 of the key is entered and abuts against the bottom surface, the turntable brake is adjusted according to the depth of the recess 25 (2004-200417669 Ο). The swing angle of the bolt 2 7 is changed, so that a plurality of the keys shown in FIG. 8 are made. Unlocked-The selected person in the ports 9, 9 is integrated with the inside edge of the lock lever 6. In addition, even in the turntable type brake lock according to the present invention, it is the same as the conventional lock lever lock, and it is preferable that the turntable type brake pins 27 adjacent to each other are provided with the engaging protrusions 29 in a symmetrical manner. This is because the distance between the recesses 2 and 25 of the key with the engaging protrusion is longer, especially when the recesses are deeper, so as not to interfere with the adjacent recesses. At least one turntable brake is applied to the turntable type brake lock of the embodiment of the present invention constructed by the above method when the key 24 is not inserted into the keyhole 4 or when a key different from the key is inserted into the keyhole 4 The unlocking notch 9 of the bolt 27 is angularly deviated from the inner edge of the lock lever 6 (see FIGS. 8 and 9). When the inner cylinder 5 is rotated in this state, although the lock lever 6 is intended to be pushed out of the cam groove 1 by the wedge action generated between the lock lever 6 and the cam 1, its action is controlled by the outer edge of the free end of the disc brake bolt 27 Prevents rotation of Inner Tube® 5. That is, the turntable brake lock cannot be turned off. In addition, when the key 24 is inserted into the keyhole 4, as described above, and as shown in FIG. 10 and FIG. 11, the unlocking notches 9, 9 of all of the turntable brake bolsters 2 7 and the Medial margin integration. When the inner cylinder is rotated in this state, it is the same as the conventional bolt lock, because the inner cylinder 5 and the outer cylinder 2 rotate with each other, the inner axis direction of the inner cylinder of the lock lever 6 can be moved, and the turntable brake is further turned away Latch. In addition, when inserting a key and a different key in the keyhole, there is no key-13-(10) (10) 200417669 The recess of the keyhole plate is engaged with the engaging protrusion 29, even if the engaging protrusion _ 29 is from the keyhole 4 When retreating, as shown in FIG. 12, the size and opening position of the key insertion hole 26 are set so as not to interfere with the key hole 4. In the locked state shown in Figs. 8 and 9, since the force of rotating the inner cylinder acts in the direction of pushing the lock lever 6 upward, the turntable brake pin 27 and the support The friction between the pins 8 disappears, so that the former's shaking becomes smooth. As shown in the figure, when a gap is set between the two, the force is held on the support shaft 23. _ This is not because of a problem in operation, but if you want to disperse the force to hold the support pin 8, you choose or set the shaft hole that fits into the shaft of all the turntable brake bolts 27, for example, up and down long Long holes are also available. At this time, when the rotary disc brake bolt 27 receives the force from the lock lever 6 and moves the rotary disc brake bolt 27 upward, its free end abuts against the support pin 8 to hold the load on the support pin. The present invention is not limited to the illustrated embodiment, and various modifications are possible. For example, in the above description, the rotary disc brake bolt 27 which enters the recess 25 of the end edge portion of the keyhole plate shown in FIG. 9 and FIG. 11 is used to enter the flat portion of the keyhole plate. The same recesses, but because the keyhole plate has a thin end edge and only two types of recess depths are used, it can be easily applied to other uses as shown in the figure. That is, for example, the entrance gate of the apartment is designed to have a turntable type brake lock 2 of a 27,27 turntable type brake lock that enters the recess 25,25 formed by the edge of the keyhole plate shown in FIG. 7, Assemble the brake bolts into the recesses formed in the edge of the keyhole plate-14- (11) (11) 200417669, and use different brake bolts that enter the recesses in the flat portion of the keyhole plate as different keys. Become a lock for occupants. Therefore, each occupant can open the lock of his house and the common door with a single key, which can constitute a so-called anti-universal key device. At this time, since it is not necessary to disperse the brake bolts from the flat portion of the keyhole plate when used in an anti-universal key device, in other words, all the disc brake locks opposed to the recess formed by the flat portion are used for occupants. The use of different keys has therefore increased the number of different keys used by occupants. On the other hand, although conventional latches such as lever locks or disc brake latches can also constitute anti-universal key devices, in the conventional latches, brake pins that should be used for different keys are converted into Applied to anti-universal key device, thus reducing the number of different keys used by occupants. In the above description, although the protrusion amount of the engaging protrusion 29 of the turntable brake bolt 27 can be set to be fixed, and the swing angle of the brake bolt can be changed according to the depth of the recess of the key, only the depth of the recess 2 5 The depth may also change the amount of protrusion of the engaging projections 29. At this time, for example, when the recess 25 is deep, if the protruding amount of the engaging protrusion 29 is increased, the swing angle of the brake bolt can be made the same even if the depth of the recess is changed. Therefore, even if the unlocking notch 9 (see FIG. 8) ) The angular position is set to be the same, and the same number of different keys as the turntable type brake lock of the illustrated embodiment can also be obtained. Figure 13 shows another embodiment of the invention described in item 1 of the scope of patent application. This embodiment moves the position of the support shaft 23 away from the direction of the center axis of the cylinder. (15) (12) (12) 200417669 By using the distance between the support shaft 23 and the lock lever 6, the longer cross-sectional shape of the key 24 can be inserted vertically into the key hole 4, in other words, the key is formed into a so-called longitudinal difference. In addition, in Figs. 13 and 13, the same reference numerals as those in other drawings indicate the same portions. The structure formed by the above method can not only double the types of latches, but also can choose an ergonomic and easy-to-operate latch according to customer preferences. In addition, since the distance between the support shaft 23 and the unlocking notch 9 is increased, if the formation position of the engaging protrusion 29 is moved to a direction close to the support shaft 23, even if the depth of the recess 2 5 only changes slightly, it can be increased. The moving distance of the large unlocking notch 9 has the advantage of improving the recognition sensitivity of the key. FIG. 14 shows a turntable brake lock of an embodiment of the invention described in item 3 of the scope of patent application. This embodiment is provided with a spring support shaft 3 parallel to the support shaft 23 and the support pin 8 on the opposite side. 2. With the bolt spring 3 1 used as a torsion coil spring, 1 each of the disc brake bolts is pressed 27 °. At this time, the coil portion of each brake bolt spring 3 1 is wound on the support shaft 3 2 so that The front ends of the open-leg springs connected to the coil portion are bent in opposite directions to each other and in a paper surface direction, so that the tumbler spring 31 can be accommodated in the narrow gap 7. A brake bolt spring 31 is used as a torsion coil spring, and a spring support shaft 3 2 is inserted in a coil portion thereof, and a conventional brake bolt spring 3 1 (Figure 8 and Figure 9) Compared with the installation method of one end rounded and inserted into the hole of the same shape as the rotary disc brake bolt 27, it can prevent the brake pin spring from disengaging -16- (13) (13) 200417669 and the malfunction of the rotary disc brake lock. [Effects of the Invention] As can be clearly understood from the above description, since the shape of the brake bolt is ring-shaped, the rigidity of the brake bolt can be improved in comparison with the conventional brake lever, and the lock can be improved. Strength and safety. In addition, because it is different from the conventional key of the lock lever, not only the V-shaped key groove formed by the edge of the key hole plate, but also the different keys can be obtained by the depth of the recess, so it is different from a recess The interval between the other recesses 25 adjacent to the position 25 may be set shorter than the conventional key groove. In other words, the number of brake bolsters can be increased in inner cylinders with restrictions on the external dimensions, and different keys can also be added. For example, although conventional brake lever locks can accommodate up to seven brake bolsters, 11 can be inserted into the disc brake lock of the present invention (see FIG. 6). Furthermore, recesses can be formed not only on the flat portion of the keyhole plate, but also on the edge portion. Using the inverse universal key device that forms a mechanical public gate in the recess on the edge portion, different keys for occupants can be used. Know more than Xi. In addition, even if the protruding amount of the engaging protrusion of the turntable type brake lock is fixed or changed, the center position is in the width direction of the keyhole plate or the width direction of the edge of the keyhole plate according to the depth of the recess. There must be subtle changes in it, so making the copy of the key difficult 'can achieve various effects such as improving the security of the latch.
