一對的乘降門2，是在三邊框3的裏面側呈左右並列地 配置。各乘降門2，是分別在上部具有吊架13。複數滾子 1 4，是在各吊架1 3的側面附近左右分開，分別設置成可旋 轉自如。各乘降門2，是藉由這些的滾子1 4可移動自如地 懸架於吊架軌道1 〇。乘降門2是藉由移動來開閉乘降口 1。 乘降門2的懸架部的構造，是如第2圖及第3圖的擴大 顯示。密閉乘降門2及三邊框3的上框8之間的間隙G1的密 閉機構1 7，是設置於此懸架部。 對於密閉機構1 7如以下說明。在面對於乘降門2的吊 架1 3的三邊框3側的側面，安裝有作爲彈性構件的板彈簧 1 8。此板彈簧1 8 ’下半部是與乘降門2幾乎相同寬，固定 於上部是吊架1 3 °板彈簧1 8的下部側的自由端側，是對於 垂直面朝向三邊框3的配置側傾斜，例如由橡膠等的彈性 -8- (6) (6)200427617 體構成的密閉構件2 0是安裝於下端緣部。 密閉構件2 0，是一體地具有中空狀的主部2 0 a、及在 此主部20a的下側延伸的舌片部20b。密閉構件20，是形 成與乘降門2的寬幾乎相同長度。 乘降門2，是在上端面具有與乘降門2幾乎相同寬的氣 密板1 9。立起壁8 a，是與三邊框3的上框8 —體形成。板彈 簧1 8，是將密閉構件2 0的主部2 0 a按壓在三邊框3的立起 壁8a，將舌片部20b按壓在乘降門2的氣密板19。 在板彈簧1 8的上下方向的幾乎中間部，與吊架軌道1〇 的側面的滾子轉動部1 〇a相面對地，安裝有被兩側分開的 一對滾子22a、22b。 滾子22a、22b，是上下位置錯開的配置的同時，分別 通過支軸23可旋轉自如地支撐於垂直軸周圍方向。 各滾子22a、22b，是藉由板彈簧18的彈力與吊架軌道 1 〇的側面的滾子轉動部1 〇a接觸。 因此，乘降門2是藉由左右方向移動，使各滾子22a、 22b，是轉動於滾子轉動部l〇a的面上。 滾子轉動部l〇a，是在各滾子22a、22b的轉動軌跡上 的途中，各別形成凹階段部、24b。乘降門2是閉合狀 態的情況下，各滾子2 2 a、2 2 b，是藉由板彈簧1 8的彈力陷 落至各凹階段部24a、2 4b內。然而，在第3圖，凹階段部 24a、24b，是方便上而顯示於同一剖面上。 一方面，門檻4，是如第1圖及第4圖 A、B所示，在 乘降口 1的下部與升降機間的底面幾乎同一面地形成並朝 -9- (7) (7)200427617 左右方向延伸地，設置成水平。導引溝2 7，是在門檻4的 上面沿著其長度方向形成。複數導引滑塊2 8，是各別安裝 在各乘降門2的下端部。各導引滑塊2 8 ’是滑動自如地嵌 合於導引溝27內。乘降門2移動的話’各導引滑塊28’是 沿著導引溝27滑動。在導引溝27的底面的長度方向的途中 的複數處，形成有垃圾排出用的透孔2 7 a ° 密閉與各乘降門2及門檻4之間的間隙G2的密閉機構 2 9，是設置於各乘降門2及門檻4之間。對於此密閉機構2 9 的說明。分別作爲彈性構件的板彈簧3 0 ’是安裝於各乘降 門2的內壁面的下部。板彈簧30，是在上下方向的幾乎中 間部具有彎曲部3 0a，上部是固定於乘降門2。 由橡膠等的彈性體構成的密閉構件3 1，是在板彈簧3 0 的下部呈水平安裝。密閉構件3 1，是使彎曲部3 0 a藉由彈 性變形而上下變位。 密閉構件3 1，是具有與乘降門2的寬幾乎相同長度， 與乘降門2的裏面滑動可能地密合。密閉構件3 1，是突出 於下緣並與乘降門2的下方的門檻4的上面相面對地，支撐 於板彈簧30。密閉構件31，是配置在門檻4的導引溝27的 偏向於升降機間側的位置。 滾子34a、3 4b，是分別通過支軸33安裝於密閉構件3 1 的兩端部。滾子3 4 a、3 4 b，是在密閉構件3 1的內側前後位 置錯開地配置，分別以水平設置的支軸3 3爲中心可旋轉自 如地被支撐。 門檻4的上面的一部分，是成爲轉動滾子34a、34b的 (8) (8)200427617 滾子轉動部4 a。如第5圖及第6圖所示，與在各滾子3 4 a、 3 4b對應的凹階段部35a、35b，是形成於滾子轉動部4a的 途中的區間的一部分。 乘降門2是閉合狀態的情況下，各滾子3 4a、3 4b，是 藉由板彈簧3 0的彈力，分別陷落至對應凹階段部3 5 a、3 5 b 內。然而，在第4圖 A、4B，凹階段部35a、35b，方便上 ，是圖示於同一剖面上。 接著，說明本發明的升降機門的密閉裝置的作用。 各乘降門2是藉由閉合使乘降口 1閉鎖的情況，如第3 圖A所示，密閉機構17的各滾子22a、22b，是分別陷落至 吊架軌道10的凹階段部24a、24b內。板彈簧18，是將設 在下端緣部密閉構件2 0的主部20a密合於三邊框3的上框8 的立起壁8 a，將舌片部2 Ob密合於乘降門2的氣密板1 9。 其結果，乘降門2及三邊框3的上框8之間的間隙G 1，是被 密閉。 且，如第4圖 A所示，密閉機構2 9的各滾子3 4 a、3 4 b ，是陷落至形成於滾子轉動部4a的各四階段部35a、35b 內。密閉構件3 1，是藉由板彈簧1 8的彈力密合於門檻4的 上面。由此，乘降門2及門檻4之間的間隙G2，是被密閉 〇 如此，各乘降門2是閉合狀態的情況，各乘降門2及三 邊框3的上框8之間的間隙G 1，各乘降門2及門檻4之間的 間隙G2，是分別被密閉。因此，對於建屋內的火災發生 的情況，可以抑制煙從升降機間朝升降路內流入，可以防 -11 - (9) (9)200427617 止升降路煙囪化。因此可以防止火災的發展’且可以防止 煙擴散至其他的樓層。 密閉構件3 1，是配置至升降機間及導引溝2 7之間’遮 蔽此間。因此，垃圾排出用的透孔2 7 a ’即使是形成於設 置於門檻4的導引溝2 7的底面’升降機間側的煙也不會流 入升降路內。 且，在平時，乘坐籠是往升降機間著地後，各乘降門 2是從閉合狀態朝左右方向移動’乘降口 1開放的情況’乘 降門2開始移動的話，密閉機構17的各滾子22a、22b ’是 分別從滾子轉動部的凹階段部24a、24b脫離。如第3 圖B所示，滾子22a、22b，是抬起至滾子轉動部l〇a的面 上，沿著滾子轉動部1 〇 a轉動。 各滾子22a、22b是抬起至滾子轉動部l〇a的面上地變 位的情況，藉由此變位使板彈簧1 8，是抵抗自己的彈力朝 吊架1 3側按壓。安裝於板彈簧1 8的下端緣部的密閉構件2 0 ，是各別從三邊框3的上框8的立起壁8 a及乘降門2的氣密 板1 9分離。在此狀態下各乘降門2，是朝乘降口 1開放的方 向移動。 如此，各乘降門2移動之間，密閉構件2 0及立起壁8 a ，是保持非接觸狀態。因此，乘降門2，是被圓滑地開放 ，且，密閉構件2 0，是被防止摩耗。且，即使乘降門2朝 關閉方向移動之間，密閉構件2 0及立起壁8 a ’是繼續保持 非接觸狀態。因此，乘降門2，是被圓滑地關閉’且，密 閉構件2 0，是被防止摩耗。 -12- (10) (10)200427617 乘降門2是到達將乘降口 1閉鎖的預定閉合位置的情況 ，如第3圖 A所示’各滾子2 2 a、2 2 b，是藉由板彈簧1 8的 彈力各別陷落至凹階段部24 a、24b內。其結果，安裝於 板彈簧1 8的下端緣部的密閉構件2 0的主部2 0 a，是密合於 三邊框3的上框8的立起壁8a，舌片部20b，是密合於乘降 門2的氣密板1 9。由此’乘降門2及三邊框3的上框8之間的 間隙G 1是被密閉。 滾子22a、22b，雖是朝左右兩側分開地設在板彈簧18 ，但這些是朝使乘降門2的厚度方向前後方向位置錯開地 配置。因此，乘降門2的各滾子22a、22b，是與對應這些 的預定的凹階段部24a、24b適切地裝卸，防止移動中誤 與其他的凹階段部24b、24a產生裝卸上的問題。 一方面，各乘降門2是從閉合狀態朝左右方向移動， 使乘降口 1開放的情況，對於設置於各乘降門2及門檻4之 間的密閉機構2 9，藉由乘降門2的移動開始，密閉機構2 9 的各滾子34a、34b，是分別從門檻4的凹階段部35a、35b 脫離。 各滾子34a、34b，是在滾子轉動部4a的面上抵抗板 彈簧3 0的彈力而抬起，轉動於其面上。 如第4圖B所示，各滾子34a、34b是被抬起於滾子轉 動部4a的面上的情況，密閉構件3 1，是與各滾子3 4a、 3 4b —體地朝上方移動，並從門檻4的上面分離。在此狀 態下各乘降門2，是朝乘降口 1打開方向移動。 如此，各乘降門2移動之間，密閉構件3 1及門檻4，是 -13- (11) (11)200427617 保持非接觸狀態。因此，乘降門2，是圓滑地移動，且密 閉構件3 1，是被防止摩耗。且，即使乘降門2朝閉方向移 動之間，密閉構件3 1及門檻4，是繼續保持非接觸狀態。 因此’乘降門2，是圓滑地關閉，且密閉構件3 1，是被防 止摩耗。 乘降門2是到達將乘降口 1閉鎖的預定閉合位置的情況 ’各滾子34a、34b，是藉由板彈簧30的彈力分別陷落至滾 子轉動部4 a的凹階段部3 5 a、3 5 b內。由此，密閉構件3 1 ，是密合於門檻4的上面，密閉乘降門2及門檻4之間的間 隙G2。 滾子3 4a、3 4b，是在密閉構件3 1的左右兩端側分開地 設置的同時，使乘降門2的厚度方向前後方向位置錯開地 配置。因此，各滾子3 4 a、3 4 b，是與對應這些的預定的凹 階段部3 5 a、3 5 b適切地裝卸，在乘降門2的移動中，防止 移動中誤與其他的凹階段部3 5 b、3 5 a產生裝卸上的問題 〇 設在乘降門2的上部的挖、閉機構1 7，是可以組入吊架 1 3的內側的空的空間內。因此，門裝置的整體的高度變大 ’可以避免門裝置大型化。 且，各密閉機構1 7、2 9的密閉構件2 〇、3 i，是藉由板 彈簧1 8、3 0的彈力密合於吊架軌道1 0的側面或門檻4的上 面。因此，密閉機構1 7、2 9，對於安裝作業不需將密閉構 件2 0、3 1微調整，就可將間隙G 1、G 2確實地密閉。 然而，在第1實施例’雖是在密閉構件3 1設置朝其左 -14- (12) (12)200427617 右的兩端側分開的一對滾子34a、34b ’是第2實施例如第7 圖，在密閉構件3 1的中間部設置1個滾子3 4也較佳。如第7 圖所示，密閉機構2 9 ’是藉由使滾子3 4朝上下方向移動’ 使密閉構件3 1與門檻4的上面接觸’分離的構造也可能。 第3實施例，是如第8圖。在此實施例中’是顯示將設 在乘降門2及三邊框3的上框8之間的間隙G 1密閉的密閉機 構的變形例。支撐吊架軌道1 〇的支架1 1 ’是具備在與乘降 門2的吊架13相面對狀態下被安裝的可動板40將。 可動板4 0的上端部，是藉由朝對於吊架1 3接離方向可 擺動自如的銷4 1所支撐。可動板40，是在接近吊架1 3的方 向藉由作爲彈性構件的彈簧42彈性地被推迫。 由橡膠等的彈性體構成的密閉構件4 5，是安裝於可動 板4 0的下端部。密閉構件4 5，是沿著吊架軌道1 0的長度方 向延伸。此密閉構件4 5，是一體地具有中空狀的主部4 5 a 、及在此主部4 5 a的下側延伸的舌片部4 5 b。主部4 5 a，是 與設置於乘降門2的上端部的氣密板1 9接觸。舌片部4 5 b， 是與三邊框3的上框8的立起壁8 a的內面接觸。 滾子軌道46，是安裝於與吊架13相面對的可動板40的 上下方向的幾乎中間部。此滾子軌道46，是沿著吊架軌道 1 〇的長度方向延伸。滾子軌道46的側面，是成爲滾子轉動 部4 6 a。滾子轉動部4 6 a的長度方向的一部分的區間，是 成爲如第9圖所示的凹階段部*4 6 b。 滾子47，是安裝於與滾子轉動部46a相面對的吊架13 的側面。滾子4 7，是通過支軸4 8可旋轉自如地支撐於垂直 (13) (13)200427617 軸周圍方向。滾子轉動部46a ’是藉由彈簧42的彈力接觸 滾子4 7。 第8圖，是顯示乘降門2的開閉動作中的狀態。 第9圖，是對於滾子轉動部4 6 a及滾子4 7的位置關係 ’開閉動作中的狀態由實線顯示，閉合狀態由2點鎖線顯 示。如第9圖實線所示’滾子4 7，是接觸滾子轉動部4 6 a， 藉由開閉乘降門2的移動而轉動於滾子轉動部46a的面上 〇 密閉構件4 5，是在乘降門2的移動中，保持氣密板！ 9 及立起壁8 a的非接觸狀態。因此，乘降門2，可進行圓滑 開閉動作，且密閉構件4 5，是被防止摩耗。 乘降門2，是沿著吊架軌道1 〇朝關閉乘降口的方向移 動，到達閉鎖升降機間的乘降口的預定的閉合位置的情況 時，滾子4 7，是如第9圖2點鎖線所示，由彈簧4 2的彈力陷 落至設置於滾子轉動部46a的凹階段部46b。 此情況，可動板4 0，是以銷4 1爲中心朝向吊架1 3轉動 。彈簧4 2，是藉由彈力，將密閉構件4 5的主部4 5 a密合呈 氣密板1 9，將舌片部4 5 b密合於立起壁8 a。由此，設置於 乘降門2及三邊框3的上框8之間的間隙G 1，是被密閉。 因乘降門2是閉合狀態，設置於乘降門2及上框8之間 的間隙G 1，是.被密閉。因此，發生火災的情況，可抑制 煙從升降機間流入升降路內，可以防止升降路成爲煙囪。 其結果，可以防止火災的發展，且可以防止煙擴散至其他 的樓層。 -16- (14) (14)200427617 乘降門2是從閉合狀態朝打開方向移動的情況，乘降 門2是與移動開始幾乎同時，使滾子47從凹階段部46b朝 滾子轉動部46a的面上相對地抬起。可動板4〇，是抵抗彈 簧42使從吊架1 3分離的方向轉動地被按壓。由此，密閉構 件4 5，是成爲從氣密板1 9及立起壁8 a遠離的非接觸狀態 。乘降門2，因爲是由非接觸狀態朝打開方向移動，所以 動作可圓滑地進行。且密閉構件4 5，是被防止摩耗。如此 ，對於第2及第3實施例，也可獲得第丨實施例的情況同樣 的效果。 在上述的各實施例，雖是以雙開式的乘降門2爲對象 ，但是對於第4實施例的第1 〇圖所示的單開式的乘降門2也 適用本發明。 但是，在升降機的乘坐籠的出入口中，設有與籠門出 入的口框及門檻。籠門，是升降機門，相當於設置於升降 機間的乘降口的乘降門。出入口框，是對於籠門的門近接 構件，相當於設置於升降機間的乘降口的三邊框。門檻， 是導引支撐籠門的下端部的開閉動作。因此，在籠門及出 入口框之間設置具有與各實施例的密閉機構同樣的構造的 密閉機構也可能。 如以上說明依據本發明，密閉裝置，是不會使門裝置 大型化，密閉構件的安裝上的微調整是不需要。且，密閉 裝置，是可將門圓滑地開閉動作並可防止密閉構件的摩耗 [產業上的利用可能性] -17- (15) (15)200427617

belongs] The present invention relates to a sealing device for a lift door that closes a gap between a lift door and a door close-up member disposed close to the lift door. [Prior Art] An elevator gate ′ in an elevator path of a house-building elevator is a wall surface provided in an elevator room. The entrance and exit are provided with a door-shaped three-frame (door close-up member). The landing door (elevator door) that opens and closes the landing door is located on the inner side of the three-frame, and the landing door is usually locked by the landing door. The landing gate is equipped with a hanger on its upper part. The hanger is equipped with a plurality of rotatable rollers. The landing port is such that the head part is inside the upper part. The head is provided with a hanger rail extending horizontally. The landing door is suspended below the hanger rail in a state where the rollers are engaged with the hanger rail. The landing gate is opened and closed by moving left and right along the hanger rail □. The sill is installed on the same level as the lower part of the landing and the bottom of the elevator. The guide groove is formed above the threshold. The guide slider is installed in the lower part of the boarding gate and is embedded in the guide groove. When the door is opened and closed, the guide slider 'slides along the guide groove. A sufficient clearance is provided between the landing gate, the three-sided frame and the sill in order to smoothly move the landing gate. Therefore, in the event of a fire in the building, even if the landing door is locked by the landing door, the smoke of the fire will flow into the elevator through the clearance between the landing door and the three borders and thresholds. The result of -4- (2) (2) 200427617, the lifting path is like a smoke burst, which will make the fire develop. Furthermore, the cage of the lift in the moving path also creates a gap between the entrance and exit of the cage and the cage door. The fire smoke will flow into the cage through this gap. Therefore, there is a danger that passengers in the cage are endangered. However, if measures are taken to close the gap, the entire door device may become large and complicated. Furthermore, adjustment work and the like in the case where these facilities are installed are also complicated. Between the lower part of the landing gate and the sill, the sealing member provided at the lower part of the landing gate and the guide groove of the sill are brought into strong contact so that the gap can be blocked. However, the frictional force between the sealing member and the guide groove increases, which hinders the opening and closing operation of the landing door, and the sealing member is worn away early. Therefore, it is necessary to reduce the contact force between the sealing member and the guide groove. However, if it weakens, the airtightness of the contact force will decrease. [Summary of the Invention] The present invention provides a sealing device for an elevator door whose door device is of the same size as the conventional one, and the fine adjustment of the installation state of the sealing member is unnecessary, and the opening and closing operation of the door device is smooth. .

When the elevator door is closed, the closed member contacts the other member by the elastic force of the elastic member. . The closed member moving mechanism is provided with a roller and a roller rotating portion which is long in a direction in which the roller rotates. The roller turning portion has a concave step portion formed in a part of the section. During the opening and closing operation of the elevator door, the roller is rotated while the roller rotating portion is pushed by the elastic force of the elastic member. Therefore, the hermetically sealed member is kept in a non-contact state with respect to other members. In the closed state of the elevator door, the roller is sunk in the recessed portion. Therefore, the elastic member of the elastic member closes the member to contact the other member and closes the gap between them. In a closing device for an elevator door according to another aspect of the present invention, the roller and the sealing member are provided on the elevator door. The roller turning part is provided on the door proximity member. During the opening and closing operation of the elevator door, the roller is rotated while contacting the roller rotating portion by the elastic force of the elastic member. Accordingly, the sealed member is kept in a non-contact state with the door proximity member. In the closed state of the elevator door, the roller is a recessed portion that has fallen into the roller rotating portion, and the closed member is closed by the elastic force of the elastic member contacting the door close member. Alternatively, in the elevator closing device according to another aspect of the present invention, the roller is provided on the elevator door. The roller turning part and the sealing member are provided in the door close-contact member. During the opening and closing operation of the elevator door, the roller is -6-(4) (4) 200427617. The roller rotates by contacting the roller rotating part with the elastic force of the elastic member. As a result, the sealed member is kept in a non-contact state with the elevator door. In the closed state of the elevator door, the roller is a recessed portion that has fallen into the roller turning portion, and the closed member closes the gap by the elastic force of the elastic member contacting the elevator door. In this case, for example, the elevator door, It is a landing door that opens and closes the landing door of the elevator. The door is close to the member. It is a three-frame border on the landing door. The airtight member closes the gap between the landing gate and the upper frame of the three-frame frame in the closed state of the landing gate. Moreover, in another form of the elevator door closing device, the elevator door is a landing door that opens and closes the landing door between elevators, and the door close-up member guides the opening and closing operation for supporting the lower end of the landing door. threshold. The closed member is the gap between the landing door and the threshold when the landing door is closed. Furthermore, in another form of the closing device of the elevator door, the elevator door is a cage door that opens and closes the entrance and exit of the riding cage of the elevator, and the door proximity structure is an entrance and exit frame provided at the entrance and exit. The closed member closes the gap between the cage door and the entrance and exit when the cage door is closed. In another form of the closing device of the elevator door, the elevator door is a cage door that opens and closes the entrance and exit of the riding cage of the elevator, and the door proximate member is a threshold that guides the opening and closing operation for supporting the lower end of the cage door. The closed member is a closed state between the cage door and the gap between the cage door and the sill. [Embodiment] -7- (5) (5) 200427617 & Next, an embodiment of the present invention will be described with reference to the drawings. The first embodiment is shown in FIGS. 1 to 6. Fig. 1 is a front view of a lift door 2 of a lift door of a lift door 1 provided between elevators as viewed from a lift path side. The landing 1 is equipped with a three-frame 3 and a threshold 4. The three bezels 3 and the threshold 4 are arranged around the landing door 2 and are close to the door proximate members of the landing door 2. The three-frame 3 is a gate shape along the periphery of the lower portion except the landing opening 1. The triple bezel 3 is formed in a door shape by a pair of vertical frames 7 arranged on the left and right sides, and an upper frame 8 bridged between upper portions of these vertical frames 7. The head 9 is integrally provided on the upper portion of the upper frame 8. The hanger rail 10 extends horizontally and is horizontally mounted on the side of the head 9 by a bracket 11 shown in Fig. 3. The pair of landing gates 2 are arranged side by side on the inner side of the three-frame 3. Each landing door 2 has a hanger 13 at the upper part. The plurality of rollers 14 are separated from each other in the vicinity of the sides of each hanger 1 3, and are respectively rotatably provided. Each of the landing gates 2 can be freely moved by these rollers 14 and is suspended on the hanger rail 10. The landing gate 2 opens and closes the landing gate 1 by moving. The structure of the suspension section of the landing gate 2 is shown enlarged in Figs. 2 and 3. A closing mechanism 17 for closing the gap G1 between the landing gate 2 and the upper frame 8 of the three-frame 3 is provided in this suspension portion. The closed mechanism 17 will be described below. A leaf spring 18 as an elastic member is attached to a side surface of the three-frame 3 side facing the hanger 1 3 of the landing door 2. The lower half of this leaf spring 1 8 'is almost the same width as the landing door 2 and fixed to the upper part is the hanger 1 3 ° The free end side of the lower side of the leaf spring 1 8 is a configuration in which the vertical plane faces the three frame 3 Side-inclined, for example, a hermetically sealed member 20 made of a resilient -8- (6) (6) 200427617 body is attached to the lower end edge. The sealing member 20 is integrally provided with a hollow main portion 20a and a tongue piece portion 20b extending below the main portion 20a. The closed member 20 is formed to be almost the same length as the width of the landing gate 2. The landing gate 2 is an airtight plate 19 having an upper end surface almost the same width as the landing gate 2. The rising wall 8 a is formed integrally with the upper frame 8 of the three-frame 3. The plate spring 18 presses the main portion 20a of the sealing member 20 against the rising wall 8a of the three-frame 3, and presses the tongue piece portion 20b against the airtight plate 19 of the landing door 2. A pair of rollers 22a and 22b spaced apart from each other are attached to almost the middle portion in the vertical direction of the plate spring 18 so as to face the roller turning portion 10a on the side of the hanger rail 10. The rollers 22a and 22b are arranged so that their vertical positions are staggered, and are rotatably supported by the support shaft 23 in the direction around the vertical axis. Each of the rollers 22a and 22b is in contact with the roller turning portion 10a on the side of the hanger rail 10 by the elastic force of the plate spring 18. Therefore, the landing gate 2 moves the rollers 22a and 22b on the surface of the roller rotating portion 10a by moving in the left-right direction. The roller turning portions 10a are formed on the middle of the turning trajectories of the rollers 22a and 22b, and the concave step portions 24b are respectively formed. When the landing gate 2 is closed, the rollers 2 2 a and 2 2 b fall into the recessed portions 24a and 24b by the elastic force of the plate spring 18. However, in Fig. 3, the concave step portions 24a and 24b are shown on the same cross section for convenience. On the other hand, as shown in FIG. 1 and FIGS. 4A and 4B, the threshold 4 is formed on the lower part of the landing gate 1 and the bottom surface of the elevator almost on the same side, and faces -9- It extends horizontally and horizontally. The guide grooves 27 are formed on the upper surface of the threshold 4 along its length. A plurality of guide sliders 28 are mounted on the lower ends of the landing gates 2 respectively. Each guide slider 2 8 'is slidably fitted into the guide groove 27. When the landing gate 2 moves, the 'each guide slider 28' slides along the guide groove 27. A plurality of holes in the longitudinal direction of the bottom surface of the guide groove 27 are formed with through-holes for waste discharge 2 7 a ° and a sealing mechanism 29 for closing the gap G2 between each of the landing doors 2 and the threshold 4 is Set between each landing gate 2 and threshold 4. Explanation of this closed mechanism 2 9. The leaf springs 3 0 ′, each of which is an elastic member, are attached to the lower portion of the inner wall surface of each landing door 2. The leaf spring 30 has a bent portion 30a at almost the middle portion in the vertical direction, and the upper portion is fixed to the landing door 2. The sealing member 31 made of an elastic body such as rubber is horizontally attached to the lower portion of the leaf spring 30. The closed member 31 is configured to displace the bent portion 30 a up and down by elastic deformation. The sealing member 31 has a length that is almost the same as the width of the landing gate 2 and may be in close contact with the inside of the landing gate 2. The sealing member 31 is projected from the lower edge and faces the upper surface of the sill 4 below the landing door 2 and is supported by the plate spring 30. The sealing member 31 is disposed at a position of the guide groove 27 of the sill 4 which is biased toward the elevator room. The rollers 34 a and 3 4 b are attached to both ends of the sealing member 3 1 via a support shaft 33, respectively. The rollers 3 4 a and 3 4 b are arranged staggered in the front and back positions of the inside of the closed member 31, and are supported rotatably around the horizontally-arranged support shaft 3 3. A part of the upper surface of the sill 4 is a roller rotating portion 4 a (8) (8) 200427617 which is a roller 34a, 34b. As shown in Figs. 5 and 6, the concave step portions 35a, 35b corresponding to the rollers 3 4a, 3 4b are part of a section formed in the middle of the roller turning portion 4a. When the landing gate 2 is closed, the rollers 3 4a and 3 4b fall into the corresponding concave step portions 3 5 a and 3 5 b by the elastic force of the leaf spring 30. However, in FIGS. 4A and 4B, the concave step portions 35a and 35b are shown on the same cross section for convenience. Next, an operation of the closing device for an elevator door according to the present invention will be described. Each landing gate 2 is closed when the landing gate 1 is closed. As shown in FIG. 3A, each roller 22a, 22b of the sealing mechanism 17 is recessed in the recessed stage portion 24a of the hanger rail 10. Within 24b. The leaf spring 18 is formed by closely adhering the main portion 20a of the lower-end edge sealing member 20 to the rising wall 8a of the upper frame 8 of the three-frame 3, and the tongue portion 2 Ob to the landing door 2. Airtight board 1 9. As a result, the gap G1 between the landing gate 2 and the upper frame 8 of the three-frame 3 is closed. As shown in FIG. 4A, the rollers 3 4a and 3 4 b of the closed mechanism 29 are sunk into the four-stage portions 35 a and 35 b formed in the roller turning portion 4 a. The sealing member 31 is brought into close contact with the upper surface of the threshold 4 by the elastic force of the leaf spring 18. As a result, the gap G2 between the landing gate 2 and the threshold 4 is closed. As such, when each landing gate 2 is closed, the clearance between each landing gate 2 and the upper frame 8 of the three-frame 3 is closed. G1, the gap G2 between each of the landing gates 2 and the sills 4, is sealed separately. Therefore, in the case of a fire in a building, the inflow of smoke from the elevator room into the hoistway can be suppressed, which can prevent the chimney of the hoistway from being prevented from becoming -11-(9) (9) 200427617. It is therefore possible to prevent the development of fire 'and to prevent smoke from spreading to other floors. The closed member 31 is arranged between the elevator room and the guide groove 27 to shield the space. Therefore, even if the through-holes 2 7 a ′ for garbage discharge are formed on the bottom surface of the guide groove 27 provided on the threshold 4, the smoke does not flow into the hoistway. In addition, in normal times, after the cage is landed on the elevator, each of the landing doors 2 is moved from the closed state to the left and right direction. "When the landing door 1 is opened" When the landing door 2 starts to move, The rollers 22a and 22b 'are detached from the concave step portions 24a and 24b of the roller turning portion, respectively. As shown in FIG. 3B, the rollers 22a and 22b are raised to the surface of the roller rotating portion 10a and rotated along the roller rotating portion 10a. Each of the rollers 22a and 22b is lifted up to the surface of the roller turning portion 10a and is displaced, and the leaf spring 18 is pressed against the hanger 13 by the displacement thereof. The sealing member 20 attached to the lower end edge portion of the leaf spring 18 is separated from the rising wall 8a of the upper frame 8 of the three-frame 3 and the airtight plate 19 of the landing door 2. In this state, each of the landing gates 2 moves in the direction in which the landing gate 1 is opened. In this way, the airtight member 20 and the rising wall 8 a are kept in a non-contact state between the movements of the landing doors 2. Therefore, the landing gate 2 is smoothly opened, and the sealing member 20 is prevented from being worn. Further, even if the landing door 2 is moved in the closing direction, the closed member 20 and the rising wall 8a 'remain in a non-contact state. Therefore, the landing door 2 is smoothly closed 'and the sealing member 20 is prevented from being worn. -12- (10) (10) 200427617 Ascending and descending gate 2 is a situation where the predetermined closing position to close the ascending and descending gate 1 is reached, as shown in FIG. 3A. 'Each roller 2 2 a, 2 2 b is borrowed The spring forces of the plate springs 18 respectively fall into the recessed portions 24 a and 24 b. As a result, the main portion 20 a of the sealing member 20 attached to the lower end edge portion of the leaf spring 18 is the rising wall 8 a and the tongue portion 20 b that are closely adhered to the upper frame 8 of the three-frame 3. The airtight board 19 for the landing gate 2. Thereby, the gap G1 between the landing gate 2 and the upper frame 8 of the three-frame 3 is sealed. The rollers 22a and 22b are provided on the plate spring 18 separately from the left and right sides, but these are arranged so as to be staggered in the front-rear direction of the boarding gate 2 in the thickness direction. Therefore, the rollers 22a, 22b of the landing gate 2 are appropriately attached to and detached from the predetermined recessed step portions 24a, 24b corresponding to these, so as to prevent erroneous movement with other recessed step portions 24b, 24a during movement. On the one hand, each landing gate 2 is moved from the closed state to the left and right, and the landing gate 1 is opened. For the closed mechanism 29 provided between each landing gate 2 and the threshold 4, the landing gate 2 The movement of 2 is started, and the rollers 34a and 34b of the sealing mechanism 29 are separated from the recessed step portions 35a and 35b of the sill 4, respectively. Each of the rollers 34a, 34b is lifted against the elastic force of the plate spring 30 on the surface of the roller rotating portion 4a, and is rotated on the surface. As shown in FIG. 4B, each of the rollers 34a and 34b is lifted on the surface of the roller rotating portion 4a, and the closed member 31 is integrally upward with the rollers 3 4a and 3 4b. Move and separate from the top of the threshold 4. In this state, each of the landing gates 2 moves in the direction in which the landing gate 1 is opened. In this way, between the movement of each landing door 2, the closed member 31 and the sill 4 remain in a non-contact state -13- (11) (11) 200427617. Therefore, the landing gate 2 is smoothly moved, and the closed member 31 is prevented from being worn. In addition, even if the landing door 2 moves in the closing direction, the closed member 31 and the threshold 4 remain in a non-contact state. Therefore, the 'departure gate 2' is smoothly closed, and the sealing member 31 is prevented from being worn. The landing gate 2 is a case where the landing gate 1 is closed to the predetermined closing position. 'The rollers 34a and 34b are respectively recessed to the concave step portions 3a of the roller rotating portion 4a by the elastic force of the plate spring 30. , Within 3 5 b. Accordingly, the sealing member 3 1 is tightly adhered to the upper surface of the threshold 4, and the gap G2 between the landing gate 2 and the threshold 4 is sealed. The rollers 3 4a and 3 4b are arranged separately from the left and right end sides of the sealing member 31, and the position of the boarding gate 2 in the thickness direction is staggered. Therefore, each of the rollers 3 4 a and 3 4 b is appropriately attached to and detached from the predetermined recessed step portions 3 5 a and 3 5 b corresponding to these. During the movement of the landing gate 2, it is prevented from being misunderstood with other members during the movement. The recessed stage portions 3 5 b and 3 5 a cause problems in loading and unloading. The digging and closing mechanism 17 provided on the upper part of the landing door 2 is an empty space that can be assembled into the inside of the hanger 13. Therefore, the height of the entire door device can be increased, and the door device can be prevented from increasing in size. In addition, the sealing members 20 and 3 i of each of the sealing mechanisms 17 and 29 are closely adhered to the side surface of the hanger rail 10 or the upper surface of the threshold 4 by the elastic force of the plate springs 18 and 30. Therefore, the sealing mechanisms 17 and 29 can reliably close the gaps G 1 and G 2 without the fine adjustment of the sealing members 20 and 31 for the installation work. However, in the first embodiment, although a pair of rollers 34a, 34b provided to the left end of the closed member 31 is disposed to the left -14- (12) (12) 200427617 right, it is the second embodiment. As shown in FIG. 7, it is also preferable to provide one roller 3 4 in the middle portion of the sealing member 31. As shown in FIG. 7, the sealing mechanism 2 9 ′ may have a structure in which the sealing member 31 is brought into contact with the upper surface of the sill 4 by moving the roller 34 in the vertical direction. The third embodiment is as shown in FIG. In this embodiment, '' is a modified example showing a hermetically sealed mechanism that closes the gap G 1 provided between the landing gate 2 and the upper frame 8 of the three-frame 3. The bracket 1 1 ′ for supporting the hanger rail 10 is provided with a movable plate 40 mounted in a state facing the hanger 13 of the landing door 2. The upper end portion of the movable plate 40 is supported by a pin 4 1 which can swing freely in a direction away from the hanger 13. The movable plate 40 is elastically urged in a direction close to the hanger 13 by a spring 42 as an elastic member. The sealing member 45 made of an elastomer such as rubber is attached to the lower end portion of the movable plate 40. The closed member 45 extends along the length of the hanger rail 10. The sealing member 45 is integrally provided with a hollow main portion 4 5 a and a tongue piece portion 4 5 b extending below the main portion 4 5 a. The main portion 4 a is in contact with the airtight plate 19 provided at the upper end portion of the landing door 2. The tongue piece portion 4 5 b is in contact with the inner surface of the rising wall 8 a of the upper frame 8 of the three-frame 3. The roller track 46 is attached to an almost middle portion of the movable plate 40 facing the hanger 13 in the vertical direction. This roller track 46 extends along the longitudinal direction of the hanger track 10. The side surface of the roller track 46 is a roller turning portion 46a. A part of the longitudinal direction of the roller turning portion 4 6 a is a concave step portion * 4 6 b as shown in FIG. 9. The roller 47 is attached to the side of the hanger 13 facing the roller turning portion 46a. The roller 4 7 is rotatably supported by the support shaft 4 8 in a vertical (13) (13) 200427617 direction around the shaft. The roller rotating portion 46a 'is in contact with the roller 47 by the elastic force of the spring 42. FIG. 8 shows a state during the opening and closing operation of the landing gate 2. Fig. 9 shows the positional relationship between the roller rotating portion 46a and the roller 47. The state during the opening and closing operation is shown by a solid line, and the closed state is shown by a two-point lock line. As shown by the solid line in FIG. 9, the roller 4 7 is in contact with the roller rotating portion 4 6 a and is rotated on the surface of the roller rotating portion 46 a by the movement of the opening and closing door 2. It is to keep the airtight panel while the landing gate 2 is moving! 9 and the non-contact state of the standing wall 8 a. Therefore, the landing door 2 can be slidably opened and closed, and the sealing member 45 can be prevented from being worn. The landing gate 2 is moved along the hanger rail 10 toward the closing of the landing gate, and when it reaches the predetermined closed position for closing the landing gate of the elevator, the roller 4 7 is as shown in FIG. 9 and FIG. 2. As shown by the dot-lock line, the elastic force of the spring 42 falls to the concave step portion 46b provided in the roller turning portion 46a. In this case, the movable plate 40 is rotated toward the hanger 13 with the pin 41 as a center. The spring 42 is tightly joined to the main portion 4 5 a of the sealing member 45 to form an airtight plate 19 by elastic force, and the tongue portion 4 5 b is adhered to the rising wall 8 a. Accordingly, the gap G1 provided between the landing gate 2 and the upper frame 8 of the three-frame 3 is hermetically closed. Since the landing gate 2 is closed, the gap G 1 provided between the landing gate 2 and the upper frame 8 is closed. Therefore, in the event of a fire, smoke can be prevented from flowing into the hoistway from the elevator room, and the hoistway can be prevented from becoming a chimney. As a result, the development of a fire can be prevented, and the spread of smoke to other floors can be prevented. -16- (14) (14) 200427617 The landing gate 2 is moved from the closed state to the opening direction. The landing gate 2 is to move the roller 47 from the recessed stage portion 46b toward the roller turning portion at almost the same time as the movement starts. The face of 46a is relatively raised. The movable plate 40 is pressed against rotation of the spring 42 in a direction separated from the hanger 13. As a result, the sealing member 45 is in a non-contact state away from the airtight plate 19 and the rising wall 8a. The landing gate 2 moves smoothly from the non-contact state to the opening direction. In addition, the hermetic members 45 are prevented from being worn. In this way, the same effects as those of the second embodiment can be obtained also in the second and third embodiments. In the above-mentioned embodiments, although the double-opening type landing gate 2 is used as an object, the present invention is also applicable to the single-opening type landing gate 2 shown in FIG. 10 of the fourth embodiment. However, the entrance and exit of the cage of the elevator are provided with a frame and a threshold for entering and exiting from the cage door. The cage door is an elevator door, which is equivalent to the landing door installed at the landing door of the elevator. The entrance and exit frame is a door close-up member for the cage door, and is equivalent to the three borders of the entrance and exit of the elevator room. The threshold is a guide for opening and closing the lower end of the cage door. Therefore, it is possible to provide a sealing mechanism between the cage door and the entrance / exit frame with the same structure as the sealing mechanism of each embodiment. As described above, according to the present invention, the sealing device does not increase the size of the door device, and the fine adjustment of the mounting of the sealing member is unnecessary. In addition, the sealing device can smoothly open and close the door and prevent abrasion of the sealing member. [Industrial Applicability] -17- (15) (15) 200427617 The present invention is a sealing device applicable to elevator doors. Sliding doors that require air tightness in the closed state are also applicable.
