201000742 六、發明說明： 【發明所屬之技術領域】 本發明係關於拉門的自動關門裝置。 【先前技術】 將開門的拉門自動地關門之裝置，乃具有數種形式， 其中一種形式，有由水平地設定在門框的上部水平框部之 直線狀的齒條；以及固定於拉門且與上述齒條作用地連結 ，並且在拉門開門後以關閉該拉門之方式來驅動之關門驅 動裝置所形成者。具體而言，關門驅動裝置，係具有：固 定於拉門之外罩；及與旋轉自如地安裝在該外罩之上述齒 條嚙合，並伴隨著拉門的開閉而沿著齒條轉動之齒輪；及 於與該齒輪之間通過上述齒條來維持該齒條與上述齒輪之 嚙合之夾持具；及在拉門的開閉時伴隨著上述齒輪沿著齒 條轉動，而儲存關閉該拉門之彈簧彈推力之彈簧裝置；以 及當藉由上述彈簧裝置將開了門且人的手離開後之拉門關 門時施以制動之制動裝置（例如參照專利文獻1 )。 此形式的自動關門裝置中，一般可利用由金屬或硬質 塑膠所形成之齒條的可撓性，即使在拉門開閉時上下移動 ，該齒條亦可因應於此而彈性變形以維持與齒輪之嚙合， 使拉門的開閉無阻礙。 [專利文獻1]日本特開平11-152955 【發明內容】 -5- 201000742 (發明所欲解決之問題） 然而，此形式之拉門的自動關門裝置中，基本上必須 水平地設定直線狀的齒條。此外，關門驅動裝置必須以使 該齒條水平地通過齒輪與夾持具之間之方式，將用以使形 成於齒輪與夾持具之間之齒條通過的齒條插通路形成爲水 平而固定於拉門。 但是，此設定作業較難，尤其是一般人購入此自動關 門裝置且欲安裝在家庭中已安裝之拉門者，乃爲極度困難 之作業。當齒條及關門驅動裝置未安裝爲水平時，即使齒 條具有上述般的可撓性，對於拉門的圓滑開閉亦容易形成 阻礙。因此，在上述專利文獻中所揭示之裝置中，係藉由 將齒條的兩端安裝爲上下移動自如，而能夠對應於拉門的 上下移動。然而，例如當關門驅動裝置斜向地通過齒條而 安裝時’對於拉門的圓滑開閉仍是容易形成阻礙。 本發明係鑒於此情形，以提供一種安裝容易，一般人 亦可簡單地安裝，且即使相當於上述齒條之構件（本發明 中爲關門驅動用索）或關門驅動裝置未設成水平，對於拉 門的開閉亦完全不會形成阻礙而能夠進行拉門的開閉之拉 門的自動關門裝置爲目的。 (用以解決問題之技術手段） 亦即’本發明係提供一種拉門（以下所述的實施型態 中’係以參照圖號2 0來表示，以下相同）的自動關門裝置 (10) ’其係具備有：關門驅動用索（18)，爲實質上未 -6- 201000742 往長度方向延伸，並且設成能夠捲繞且柔軟之關門驅動用 索（1 8 )，係往拉門的開閉方向延伸，且位於兩端之關門 位置側端部（24 )與開門位置側端部（26 )被安裝在拉門 及門框的一方；以及 關門驅動裝置（22 )，爲固定於該拉門及門框的另一 方之關門驅動裝置（22 )，其係具有：相對於該拉門及門 框的該另一方，能夠旋轉地安裝在特定位置之軸線的周圍 之旋轉構件（32);及將該關門驅動用索卡合於該旋轉構 件的周面，且伴隨著該拉門的開閉動作使該旋轉構件於該 關門驅動用索上進行轉動之卡合保持構件（36);以及伴 隨著拉門從關門位置朝向開門位置移動時之該關門驅動用 索與該關門驅動裝置的相對性動作，使該旋轉構件在該關 門驅動用索上轉動，且伴隨於此而儲存用以使該旋轉構件 朝向與該轉動相反方向進行轉動之彈簧彈推力之彈簧裝置 〇 此自動關門裝置中，由於關門驅動用索實質上未往長 度方向延伸，並且設成能夠捲繞且柔軟，所以在將該索設 定在拉門的關門方向時，不一定需如前述的先前裝置般必 須正確地平行設定在開閉方向。亦即，即使該索例如在鬆 緩的狀態下，該索亦可藉由卡合保持構件卡合於旋轉構件 ，並且構成爲能夠捲繞且柔軟之程度，所以不會有過度的 力施加於該索，對於拉們的圓滑開閉不會造成阻礙。此外 ，即使斜向地設定該索，由於該索爲柔軟’所以對於旋轉 構件沿著該該索之轉動不會造成阻礙。關門驅動裝置的設 201000742 定亦相同。 因此，相較於前述以往的自動關門裝置，其安裝極爲 容易，一般人亦可輕鬆地設定。 具體而言，可將關門驅動用索保持鬆弛來安裝在拉門 及門框的一方。藉由使關門驅動用索具有某種程度的鬆弛 ，不需嚴密地定位關門驅動裝置而安裝，因此可輕鬆地設 定。 此外，可將該關門驅動用索安裝在該門框，並夾介線 圈彈簧（44 )等之能夠在拉門的開閉方向上伸縮之構件， 將該關門驅動用索的開門位置側端部安裝在門框。或者是 將關門驅動用索安裝在拉門，並夾介能夠在拉門的開閉方 向上伸縮之構件，將該關門驅動用索的關門位置側端部安 裝在拉門。 藉此，可在拉門的開閉方向上，容易以不具鬆弛的狀 態將關門驅動用索安裝在門框，且即使關門驅動用索與關 門驅動裝置的旋轉構件及卡合保持構件之間不完全匹配， 亦不會無法配合。 此外，關門驅動用索（1 8 )可構成爲具有沿著該長度 方向以一定間距所設置之齒條齒（2 8 )，該旋轉構件的該 周面具有以嚙合於該齒條齒之間距所設置的齒。 旋轉構件的該周面與該關門驅動用索亦可構成爲摩擦 卡合，來取代如上述般設置齒條齒之方式。 再者，可構成爲關門驅動裝置具有能夠裝卸地固定於 其所安裝之拉門或門框的外罩，該外罩係收納該旋轉構件 -8 - 201000742 、該卡合保持構件、及該彈簧裝置，而能夠將關門驅動裝 置構成爲一體安裝在拉門。具體而言，外罩具有拉門的開 閉方向側壁，於該側壁具有開口，此開口作爲使纜線通過 之開口’亦即不會妨礙在該拉門的自動關門裝置之設定時 所可能產生的撓曲之尺寸的開口。 此外，本發明亦提供一種具有拉門及門框，並安裝有 上述自動關門裝置之拉門裝置。 此外，本發明更提供一種拉門的自動關門裝置套件， 其係具備有：關門驅動用索，爲實質上未往長度方向延伸 ，並且設成能夠捲繞且柔軟之關門驅動用索，係往拉門的 開閉方向延伸，且位於兩端之關門位置側端部與開門位置 側端部被安裝在拉門及門框的一方；以及 關門驅動裝置，其係具有：固定於該拉門及門框的另 一方之外罩；及能夠旋轉地安裝在該外罩，且能夠旋轉地 安裝在特定軸線的周圍之旋轉構件；及作爲安裝在該外罩 之卡合保持構件，亦即使該關門驅動用索通過該卡合保持 構件與該旋轉構件之間，並將該關門驅動用索卡合於該旋 轉構件的周面，藉此，當該關門驅動用索於該旋轉構件與 該卡合保持構件之間在該關門驅動用索的長度方向上位移 時，使該旋轉構件於該特定軸線的周圍旋轉之卡合保持構 件；以及安裝在該外罩，且伴隨著該關門驅動用索於該旋 轉構件與該卡合保持構件之間朝該關門驅動用索的長度方 向的特定一方位移來藉此使該旋轉構件於該關門驅動用索 上，進行旋轉動作，而儲存用以使該旋轉構件朝向與該轉 -9- 201000742 動相反方向進行轉動之彈簧彈推力之彈簧裝置； 該關門驅動用索之從該外罩往外延伸的部分，係構成 爲捲繞狀態。 具體而言，可構成爲關門驅動用索之從該外罩往外延 伸的部分爲撓曲，且該關門驅動用索構成爲全體至少僅捲 繞成一捲之狀態。 由於關門驅動用索爲捲繞，所以可將該套件收納更輕 巧，而更容易進行流通販售。 該關門驅動用索可藉由線圈彈簧構成其一端部分而成 0 再者，具有：載置關門驅動用索及關門驅動裝置之支 撐薄片；以及以覆蓋支撐薄片上的關門驅動用索及關門驅 動裝置之方式地接觸於支撐薄片而安裝之罩蓋材的自動關 門裝置套件，更容易進行流通販售。具體而言，該罩蓋材 可構成爲透明。 本發明中，更提供一種自動關門裝置套件的設定方法 ，係準備上述自動關門裝置套件； 將關門驅動裝置的外罩固定於拉門及門框的一方； 在關閉拉門之狀態下，將關門驅動用索的關門位置側 端部固定於拉門及門框的另一方； 將關門驅動用索往該拉門的開閉方向延伸，並將關門 驅動用索的開門位置側端部固定於拉門及門框的另一方； 將自動關門裝置套件設定在該拉門及門框。 預先固定關門驅動裝置，並在開閉方向上使關門驅動 -10- 201000742 用索相對於該關門驅動裝置進行適當的位移，藉此可容易 且適切地設定該關門驅動用索。 其他方法例如爲：係準備上述自動關門裝置套件； 將關門驅動用索的關門位置側端部固定於拉門及門框 的一方； 關閉拉門，在將關門驅動用索從固定的關門位置側端 部往拉門的開啓方向延伸之狀態下，將關門驅動裝置的外 罩固定於拉門及門框的另一方； 在將關門驅動用索從關門位置側端部往開門位置側端 部的方向延伸之狀態下，固定於該拉門及門框的該一方； 將該自動關門裝置套件設定在該拉門及門框。 此時，預先形成爲將關門驅動用索的關門位置側端部 固定於拉門及門框的一方之狀態，可適當地定位關門驅動 裝置，因此可容易且適切地進行設定。 本發明中，更可將自動關門裝置（22)構成如下：該 彈簧裝置，係具有：構成爲與該旋轉構件呈同軸狀之軸體 ;及 使一端連結於該軸體並捲繞於該軸體的周圍，另一端 與該旋轉構件的內壁面連結之發條彈簧，亦即拉門從關門 位置朝向開門位置移動時在該關門驅動用索上進行轉動， 並藉由對該軸體相對地旋轉之該旋轉構件而被捲入於該軸 體的周圍之發條彈簧；及 固定於該軸體的一端’具有大致呈圓形的外周面’並 在該周方向上具有隔著間隔所設置之複數個凹部（154) -11 -
