200927026 九、發明說明 【發明所屬之技術領域】 本發明係有關設置在廚具之上方的昇降式吊櫃。 【先前技術】 在廚房（galley)中，由於在廚具（kitchen)等之調理設 備的上部空出空間，因此在廚具的上方設置吊櫃的情形具 多。在廚房使用碗、盤、杯子等之食器類、鍋、平底鍋等 之調理器具、鹽、胡椒等之調味料等大大小小的各種物 品。因此’該等之食器類、調理器具、調味料等被收納在 上述吊櫃。 而且隨著生活樣式和飮食生活的多樣化，上述的食器 類、調理器具、調味料等有增加傾向。更隨著現今的高齡 化，亦有追求上述吊櫃之使用方便的優異度和便利度等的 要求。 於是普遍提供一種利用手動或電動來昇降位於上方的 架子（rack )的昇降式吊櫃。昇降式吊櫃例如有：吊櫃整 個進行昇降者（例如日本專利文獻1)、打開配置在吊櫃之 前面的門片後，利用旋轉臂來支承設置在吊櫃內的收納架 同時拉降到跟前側下方者（例如日本專利文獻2)、具備廚 櫃、和可從該廚櫃大致朝垂直方向昇降的昇降架者（例如 日本專利文獻3)等。 在曰本專利文獻1所記載的構造，由於吊櫃整個進行 昇降，因此昇降裝置變得很龐大，且由於從外部看得見驅 -5- 200927026 動機構，因此會有所謂難以提升美感的問題。而在日本專 利文獻2所記載的構造’由於拉降的收納架是向著調理者 而旋轉下降，因此調理作業變得很麻煩’必須頻繁的取放 收納架，會有所謂費事的問題。因此近年來，如日本專利 文獻3所記載的’多數採用具備可從蔚櫃大致朝垂直方向 昇降的昇降架之構造。 但是在使其朝垂直方向昇降的構造中，爲了露出昇降 架的整面，在廚櫃的下方需要僅將昇降架整個下降到廚櫃 下方的行程。換言之，變成在廚具的上方至天花板的吊櫃 所使用的空間之中，只能設置一半高度的吊櫃。而且實際 上由於必須將供昇降的驅動機構設置在厨櫃內，因此昇降 架的容積變更小。再者，一般家庭天花板的高度一般爲 2.3m左右，廚具的高度爲85cm左右。更必須在廚櫃之上 餘留貯藏室和供放置小物品架的高度。而且如果剩餘的上 方空間之高度之中的一半以下爲昇降架之高度的話，上昇 降架的容積可說是不夠的。 於是自以往也揭示一種使廚櫃的前面門片與昇降架的 上下動作一起連動而開關，在下降昇降架的狀態，昇降架 的上端是位在比廚櫃的下端更上方的構造（例如日本專利 文獻4)。若藉由此構造，由於也能從隱藏在前面門片之 錯開的位置出入，因此能提高昇降架的高度，在有限之高 度的上方空間，設置容積大的昇降架。 [專利文獻1]日本特開平11 -4 6886號公報 [專利文獻2]日本特開2004- 222886號公報 200927026 [專利文獻3]日本特開2006-000677號公報 [專利文獻4]日本特開2006 - 340756號公報 【發明內容】 [發明欲解決之課題] 但在專利文獻4所記載的構造，由於門片的下端是轉 動打開的構造，因此前面的開放空間很小。因此，尤其是 昇降架的上段會有難以取放鍋或置物箱等之較大物品的問 題。雖然也考慮將門片開的更大，但爲了在吊櫃的前方大 大的拉開門片，反而會造成前板壓迫在頭上，具有賦予壓 迫感之虞。 於是本發明之目的在於提供一種縮短下降昇降架的行 程，謀求增大容積的同時，將隨著門之動作的壓迫感停留 在最小限的昇降式吊櫃。 [用以解決課題之手段] 爲了解決上述課題’有關本發明之昇降式吊櫃的代表 个生構造，係爲具備：底面與前面爲開放的廚櫃與可相對於 廚櫃昇降地被支承的昇降架，且設置在廚具之上方的昇降 式吊櫃，其特徵爲：具備：配置在廚櫃之前面且上方的上 門片、和配置在廚櫃之前面且下方的下門片’下門片會轉 入到上門片的下端，以沿著其表面的方式上昇。 若藉由上述構造，即可提供一種縮短下降昇降架的行 程，謀求增大容積的同時’將隨著門之動作的壓迫感停留 200927026 在最小限的昇降式吊櫃。 在下門片的兩側緣分別設置上側被引導部及下側被引 導部，且在廚櫃的兩側壁分別設置引導上側被引導部的上 導件及引導下側被引導部的下導件’上導件及下導件亦可 具備：隨著將上側被引導部或下側被引導部從該停止位置 往上移行，而朝向廚櫃之前方引導的傾斜部、和接續於傾 斜部大致朝垂直方向引導的直線部。 & 若藉由上述構造，即可將下門片隨著往上方移動，且 藉由傾斜部先往廚櫃前方移動，接著沿著上門片的前方側 而上昇。藉此下門片會轉入到上門片的下端，以沿著其表 面的方式上昇。 相對於鉛直線的傾斜是上導件的傾斜部大於下導件的 傾斜部爲宜。藉此，下門片的上端變得比下端還要先往廚 櫃前方移動，就能圓滑地轉入到上門片的下端。 在前述上導件或下導件中，當從上側被引導部或下側 Q 被引導部的停止位置至直線部的水平距離爲拉開寬度時， 上導件的拉開寬度較下導件的拉開寬度長爲宜。藉此，下 門片以其上端拉出更多的傾斜狀態進行上昇。因而，能在 使用者的頭上確保擴大至最大限的空間，且能防止因下門 片而蒙受壓迫感。 此外也可構成具備牽引下門片而使其上昇的牽引部， 藉由解除因牽引部的牽引’讓下門片因自重而下降。雖然 也考慮到利用馬達與齒輪等的驅動，但若藉由上述軌導及 被引導部的構造’即可因往上方的牽引與利用自重的下降 -8 - 200927026 而使其進行昇降動作，謀求驅動機構的簡略化。 亦可構成牽引部係由：滑輪、和經由滑輪而將昇降架 與下門片垂懸在兩端的索體所形成，且藉由昇降架進行下 降之際的荷重來牽引下門片。藉此由於昇降架與下門片爲 機械式地連動，因此能利用昇降架的驅動源來供應用以使 下門片昇降的驅動力。 [發明效果] 若藉由本發明，即可提供一種縮短下降昇降架的行 程，謀求增大容積的同時，將隨著門之動作的壓迫感停留 在最小限的昇降式吊櫃。 【實施方式】 [用以實施發明的最佳形態] 以下邊參照所附圖面、邊針對本發明之最佳的實施形 Q 態做詳細說明。再者，在本詳細說明書及圖面中，有關實 際上具有同一機能構造的構成要素，係附上同一符號，藉 此省略重複說明。再者，以下之實施形態所示的尺寸、材 料、其他具體的數値等，只不過是爲了易於本發明之理解 的範例，尤其除了事先設定的情形，否則並非用來限定本 發明。 在本實施形態中，係使得廚房用昇降式吊櫃（叫下簡 稱「吊櫃」）的昇降架與關閉昇降架之前面的下門片一起 連動’使兩裝置互相地朝逆向移動。因而，雖未加長昇降 -9- 200927026 架的下降行程卻能充分地確保前面的開放空間。而且下門 片係具有在上昇之際會轉入到上門片的下端，沿著其表面 而上昇的特徵。在此爲了易於本實施形態的理解，首先針 對吊櫃的配置及驅動機構做說明，然後在詳述本實施形態 的特徵。 第1圖是表示本實施形態的系統廚具與吊櫃之位置關 係的立體圖。系統廚具100是以調理所需要的火（加熱）或 水爲中心，調理器具配合其大小配設在各收納庫。雖然吊 櫃110是設置在系統廚具100的上方，但無法開關位在高 處的門，收納部分要下降到廚具使用者之眼睛的高度，手 伸到前方來收納或取出被收納物。 上述系統廚具100是以水槽130、調理空間140及爐 具150之大致三個部位所構成。這樣的系統廚具1〇〇之 中，在相當於水槽130及調理空間140之寬度的區域的上 方，吊櫃110是將背面固定支承在牆壁500。另一方面， 在處理火焰的爐具150之上方，係鄰接於吊櫃110，而將 抽油煙機160與吊櫃同樣的固定支承在牆壁500。 吊櫃1 10包括：下方爲開放的廚櫃107、在厨櫃170 之下方朝向廚櫃170之內外昇降的昇降架180。昇降架 1 80具有收納部，前面的大部分爲開放，能取放食器或廚 房周邊的物品。 此外，在廚櫃170的前面配置有上門片172和下門片 174，當昇降架180下降出現在廚櫃170之下方時，下門 片174會與此一起連動往上方移動。因此，昇降架180的 -10- 200927026 上端會比廚櫃170的下端更爲下降，同時昇降架丨8〇的開 放前面會出現在使用者的眼前。可藉由這樣的構造讓昇降 架180的可動範圍變窄，縮短昇降動作的時間，或加大吊 櫃11〇之高度方向的尺寸達到增大容積。以下，針對使昇 降架180與下門片174 —起連動的驅動機構做說明。 (昇降架的驅動機構） 第2圖是表示昇降架180的驅動機構的圖。在此，主 要是說明昇降架180的昇降動作，由吊櫃11〇前面側進行 觀察。此外爲了易於理解，在第2圖省略下門片174的圖 不 ° 首先，藉由驅動馬達190的旋轉，在水平方向左右從 驅動滑輪（pulley)192起捲繞兩條寬型索體200。該寬型索 體2 00是藉由固定設置在廚櫃170之兩側板附近，作爲定 滑輪之功能的轉向滑輪210而朝垂直方向轉向，且捲繞端 部分別被固定於昇降架1 80，作爲動滑輪之功能的昇降滑 輪212，而固定在廚櫃170的上方。因而，可藉由讓驅動 馬達190旋轉驅動來進行昇降架180的昇降。在此，索體 不限於繩索’也包括帶體。 如此一來’若昇降架180下降的話，收納部220就會 從下門片174(圖未示）的背面出現。 (下門片的驅動機構） 第3圖是表示與昇降架180 —起連動的下門片174的 -11 - 200927026 驅動機構（牽引部）的圖。這樣的第3圖是從側面來觀察吊 櫃110。在此’下門片174是進一步與第2圖所示的昇降 架180 —起連動而昇降。 第3圖（a)是表示昇降架18〇收納在蔚櫃17〇的狀 態。在昇降架1 80與下門片i 74之間固定設置著作爲定滑 輪的下門片用滑輪250。下門片用滑輪25〇係連結著兩個 捲軸（第1捲軸252、第2捲軸254)，且軸相等而旋轉自 如地軸支。而且，在第1捲軸252捲繞著懸吊昇降架180 的第1索體260，在第2捲軸254捲繞著懸吊下門片174 的第2索體262。 在此，因爲分別懸吊昇降架180與下門片174的第1 索體260及第2索體262，係相對於捲軸而互相地逆轉捲 繞’所以一旦昇降架1 80或下門片1 74之一方上昇的話， 另一方就會一起連動並因自重而下降。 第3圖（b)是表示昇降架180從廚櫃170抽出（下降）的 狀態。若昇降架180被導軌264引導並且下降的話，第1 索體260會拉動第1捲軸252，與第1捲軸252連結的第 2捲軸254會以旋轉軸256爲中心，僅旋轉與第1捲軸 252相同的角度量。而且，藉由第2捲軸254的捲張力讓 接續於第2索體262的連結部26 6與下門片174上昇。因 而，因爲下門片174會配合昇降架180的下降而上昇，其 移動量之和成爲昇降架1 80的開放空間，所以雖未加長下 降行程卻能充分地確保昇降架1 80之前面的開放空間。 此時，由於昇降架180及下門片174的荷重會以旋轉 -12- 200927026 軸256爲中心互相地逆向施力，因此使第1捲軸252及第 2捲軸254旋轉的張力會互相抵銷，能減輕將昇降架18〇 及下門片174移動及維持在任意位置的負荷，就能謀求省 電、低成本化。 此外，若注意到第3圖之下門片用滑輪250的話，就 會了解到第1捲軸2 52與第2捲軸25 4之索體的捲繞部分 的直徑並不相同。藉由這樣的構造，就能配合該吊櫃110 的用途而任意地設定昇降架180與下門片174的昇降行程 比。 尤其在第3圖中，捲繞著懸吊下門片174之索體的第 2捲軸254的直徑，爲小於捲繞著懸吊昇架180之索體的 第1捲軸252的直徑。如第3圖所示吊櫃1 1〇，是假設在 下方具有某種程度的可佔有空間，在上方沒有的設置狀 況。因此，雖然昇降架180能下降其高度H1量，但直至 下門片重疊於上門片爲止，亦即僅能上昇昇降架之約一半 的長度H2。對應於這樣的下門片174之第2捲軸254的 直徑與對應於昇降架之第1捲軸252的直徑之比，例如可 爲 H2/Hi，Hi= 450mm、H2 = 200mm的情形下，直徑之比 爲4/9即可。像這樣，第2捲軸254的直徑小於第1捲軸 252，不使用其他特別的機構就能實現上述的行程差。 (來自驅動馬達的連動） 如上所述，昇降架180是以驅動馬達190作爲動力源 而昇降，下門片是以昇降架1 80作爲間接性的動力源而昇 -13- 200927026 降。藉由這樣的構造利用一個動力源（驅動馬達）就能控制 昇降架180及下門片174之兩方的昇降。 第4圖是比對利用驅動馬達1 90的驅動機構與利用昇 降架180的驅動機構的說明圖。在此’由驅動馬達190對 昇降架180傳達動力的機構與由昇降架180對下門片174 傳達動力的機構是獨立的，能將各個動力的傳達方向限制 在面方向。例如，因爲由驅動馬達190對昇降架180傳達 動力的機構，只能在YZ面的轉向達成，所以只要利用索 體與滑輪的組合就能實現傳達機構。同樣的，由昇降架 180對下門片174傳達動力的機構，亦只能在ZX面之利 用索體及滑輪的組合轉向達成。 藉由上述構造，可因昇降架180下降之際的荷重而往 上方牽引下門片174。像這樣由於昇降架180與下門片 174是機械式的連動，因此能利用昇降架180的驅動源來 供應用以使下門片1 74昇降的驅動力。進而，因爲下門片 174不能直接由驅動馬達190承受動力，所以在昇降架 1 80因任何事故而不能昇降的情形下，下門片1 74也會跟 著連動而停止。因此，反而昇降架180會停止只有下門片 174會動作，不會產生二次性傷害。 (下門片的引導機構） 其次，說明有關下門片的引導機構與動作。第5圖是 說明下門片之引導機構的圖。 第5圖（a)是說明引導機構的分解圖。在下門片174 -14- 200927026 之兩側緣的背面，係在連結部266分別安裝著用來安裝下 門片174的門驅動組件176。在連結部266係設有屬於上 側被引導部的上滾子26 8與屬於下側被引導部的下滾子 270。此外在連結部266的上端，係設有用來安裝第2索 體262的吊掛部272。在廚櫃170的兩側壁分別設有引導 組件280。在該引導組件280係設有引導上滾子268的上 導件282與引導下滾子270的下導件284。此外在引導組 件280具備後述的收容機構390。 在上導件282及下導件2 84的下端分別形成有大徑部 2 82a、2 84a，能插入上滾子268與下滾子270的頭。此外 各個導件是具備：隨著從上滾子268或下滾子270的停止 位置（大致下端的位置）往上移行，並朝向廚櫃170之前方 引導的傾斜部282b、284b、和接續於傾斜部282b、284b 大致朝向鉛直方向引導的直線部282c、284c。 上導件282及下導件284是做成上述形狀，藉此隨著 下門片174往上方移動，下門片174會因傾斜部282b、 284b而先往廚櫃前方移動，接著因直線部282c、284c而 沿著上門片1 72的前方側上昇。藉此下門片1 74會轉入到 上門片172的下端，以沿著其表面的方式上昇。 第5圖（b)是引導機構的組裝圖。上滾子268及下滾 子270係令其頭嵌合於上導件282及下導件284，就能滑 動。在連結部266的吊掛部272安裝懸垂著第2索體 2 62，藉此讓下門片1 74停止。從該停止位置，第2索體 將連結部266朝上方牽引，藉此上滾子268及下滾子270 -15- 200927026 會被上導件282及下導件284引導，同時下門片174會上 昇。 第6圖是說明下門片之動作的圖，邊參照第5圖（b) 之導件的形狀、邊說明下門片的動作。 第6圖（a)是表示處於停止位置的狀態。從該狀態被 第2索體262牽引，藉此下門片174就會開始動作。此時 如第5圖（b)所示，相對於鉛直線的傾斜是上導件282的 傾斜部2 8 2 b大於下導件2 8 4的傾斜部2 8 4 b。藉此，如第 6圖（b)所示’下門片174的上端比下端更先往廚櫃前方開 始移動。而且如第6圖（c)所示，下門片174的上端比上 門片172的下端更往前方移動之時，直至上滾子268及下 滾子270到直線部282c、284c爲止，如第6圖（d)所示， 開始上昇。而且若上昇到直線部282c、284c之上端的 話，如第6圖（e)所示，下門片174的上側與上門片172 的下側成爲重疊的狀態。 第7圖是說明下門片174、連結部266、上滾子 268、下滾子270之軌跡的圖。若參照第7圖，即知下門 片174的上端會轉入到上門片172的下端，而且下門片 174會沿著上面片172的表面而上昇。 上滾子268及下滾子270到了直線部282c、284c之 後，下門片174的姿勢（傾斜角度）依舊不變的進行上昇。 在此如第5圖（b)所示，從上導件282之上滾子268的停 止位置至直線部282c的水平距離爲拉開寬度wi，從下導 件284之下滾子270的停止位置至直線部284c的水平距 -16- 200927026 離爲拉開寬度w2。而且在本實施形態中，上導件的拉出 寬度wl設定的比下導件的拉出寛度W2長。 藉此，下門片174係在上端拉出更多且拉開至廚櫃前 方的傾斜狀態下進行上昇，停止的期間保持其姿勢。藉 此’能在使用者的頭上確保擴大至最大限的空間，且能防 止因下門片而蒙受壓迫感。 當下門片174關閉時，亦即當昇降架180上昇時，下 門片174係將第6圖所示的上昇過程反過來走而下降，被 收納在上門片172的下方。此時藉由收容機構390的動 作，到最後確實的關閉。 說明有關收容機構3 90的構造與動作。如第5圖（a) 所示，收容機構3 90係具備：設置在引導組件280的上 部，且將中途部旋轉自如地軸支在引導組件280的支臂 390a、和設置在支臂之一端的滾子390b、和向著廚櫃內 側推彈滾子3 90b的彈簧3 90c(推彈手段）。另一方面’在 連結部266設有用以令收容機構390之滾子39 0b移行的 收容導件266a。收容導件266a係爲剖面C字狀的溝形 狀，滾子3 90b爲抵接在其側壁，藉此就能向著蔚櫃內側 推彈連結部2 6 6。 當下門片174如上述上昇時，如第6圖所示，因爲滾 子390b是抵接在收容導件266a的側壁，所以收容機構 390會頂抗彈簧390c的推彈力而旋轉。再者，當上滾子 268及下滾子270位在直線部時，由於收容機構3 90的推 彈力大致與導溝的方向呈直交，因此沒有妨礙上昇力之 -17- 200927026 虞。而且當下門片174關閉時’尤其上滾子268、下滾子 270位在傾斜部282b、284b時，收容機構3 90的彈簧 3 9 0c的推彈力會作用於收容下門片174的方向。 在此，假設由於只因自重而令下門片174關閉時，且 上滾子268及下滾子270位在傾斜部282b、284b時會形 成分力，因此收容之方向的力會減弱。因此下門片1 74到 最後不會關閉，會有自上門片172稍微浮起的狀態下移動 U 就結束之虞。但因爲設置上述構造的收容機構390，藉此 特別將連結部266的上端向著廚櫃170的內側推彈，所以 能確實地將下門片174收容到上門片172的下方。 以上，如已說明的，本實施形態的吊櫃1 1 0，雖未加 長昇降架180的下降行程卻能充分地確保前面的開放空 間，縮短下降昇降架的行程，謀求增大容積。此外下門片 會轉入到上門片的下端，沿著其表面而上昇，藉此就能將 隨著門之動作的壓迫感停留在最小限，就能提升的廚房用 Q 昇降式吊櫃的使用方便。 以上，雖是參照所附圖面並針對本發明的最佳實施例 所做的說明’但本發明當然不限於這樣的範例。只要是熟 悉此技藝者’即了解到顯然在本案申請專利範圍所記載的 範疇內’得以思及各種的變更例或修正例，有關於此當然 亦屬本發明之技術性範圍。 [產業上的可利用性] 本發明係可利用作爲設置在廚具之上方的昇降式吊 -18 -

Description of the Invention [Technical Field of the Invention] The present invention relates to a lift cabinet disposed above a kitchen utensil. [Prior Art] In a galley, since a space is left in the upper part of a conditioning device such as a kitchen, there are many cases in which a wall cabinet is placed above the kitchenware. In the kitchen, various utensils such as bowls, plates, cups, and the like, utensils such as pots and pans, seasonings such as salt and pepper, and the like are used. Therefore, such food utensils, conditioning equipment, seasonings, and the like are housed in the hanging cabinet. Moreover, with the diversification of lifestyles and foraging life, the above-mentioned food utensils, conditioning equipment, seasonings, and the like tend to increase. With the aging of today, there is also a demand for excellence and convenience in the use of the above-mentioned wall cabinets. Thus, there is a general provision of a lift cabinet that uses manual or electric power to lift a rack located above. For example, the lift cabinet is provided with a lifter (for example, Japanese Patent Document 1), and after opening the door panel disposed in front of the cabinet, the swing arm is used to support the storage rack provided in the cabinet and simultaneously pulled down to The lower side (for example, Japanese Patent Document 2), the kitchen cabinet, and the lifter that can be vertically moved up and down from the kitchen cabinet (for example, Japanese Patent Laid-Open No. 3). In the structure described in Patent Document 1, since the ceiling is lifted and lowered as a whole, the lifting device becomes very large, and since the external mechanism is seen from the outside, there is a problem that it is difficult to enhance the aesthetic feeling. . In the structure described in Japanese Patent Publication No. 2, the storage rack that is pulled down is rotated downward toward the conditioner, so that the conditioning work becomes troublesome. The storage rack must be frequently picked up and stored, which is a problem that is complicated. Therefore, in recent years, as described in Japanese Patent Laid-Open No. 3, a structure having a lifting frame that can be raised and lowered substantially in the vertical direction from the cabinet is used. However, in the structure in which the vertical direction is raised and lowered, in order to expose the entire surface of the elevator, it is necessary to lower the entire lifting frame to the lower side of the kitchen cabinet below the kitchen cabinet. In other words, it is only possible to set a cabinet of half the height among the space used in the cabinet from the top of the kitchen to the ceiling. Further, since the driving mechanism for lifting and lowering must be disposed in the kitchen cabinet, the volume of the lifting frame is small. Furthermore, the height of the general household ceiling is generally about 2.3 m, and the height of the kitchen utensil is about 85 cm. It is even more necessary to leave a storage room on the kitchen cabinet and a height for placing small items. Moreover, if less than half of the height of the remaining upper space is the height of the crane, the volume of the ascending and descending frame is not sufficient. Therefore, since the past, a switch has been disclosed in which the front door piece of the kitchen cabinet and the up and down movement of the lifting frame are linked together, and in the state of descending the lifting frame, the upper end of the lifting frame is located above the lower end of the kitchen cabinet (for example, Japan). Patent Document 4). According to this configuration, since the height can be increased from the position where the front door piece is staggered, the height of the crane can be increased, and a large-sized crane can be provided in a limited upper space. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. 2006-000677. - [Abstract] [Problem to be Solved by the Invention] However, in the structure described in Patent Document 4, since the lower end of the door piece is rotated and opened, the front open space is small. Therefore, in particular, the upper section of the crane has a problem that it is difficult to take a large item such as a pan or a storage box. Although it is also considered to open the door piece larger, in order to open the door piece in front of the wall cabinet, the front plate is pressed against the head, which gives a feeling of pressure. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a lift cabinet which minimizes the stroke of a descending crane and which is capable of increasing the volume while maintaining a minimum pressure with the action of the door. [Means for Solving the Problem] In order to solve the above-mentioned problem, the representative living structure of the elevating wall cabinet according to the present invention includes a kitchen cabinet whose bottom surface and the front surface are open and which can be supported by the kitchen cabinet. a lifting frame, and a lifting wall cabinet disposed above the kitchenware, characterized in that: a door piece disposed on the upper side of the kitchen cabinet and above, and a lower door piece disposed under the kitchen cabinet and below the door piece It will be transferred to the lower end of the upper door piece to rise along its surface. According to the above configuration, it is possible to provide a method of shortening the movement of the descending crane, and at the same time as increasing the volume, the pressure will be maintained with the action of the door. 200927026 The minimum lift cabinet. An upper side guided portion and a lower side guided portion are respectively disposed on both side edges of the lower door piece, and upper guides for guiding the upper side guided portion and lower guide members for guiding the lower side guided portion are respectively provided on both side walls of the kitchen cabinet. The upper guide and the lower guide may further include an inclined portion that is guided toward the front of the kitchen cabinet as the upper guided portion or the lower guided portion moves upward from the stop position, and the inclined portion that is continuous toward the inclined portion A straight line that is guided in the vertical direction. & With the above configuration, the lower door piece can be moved upward, and the inclined portion first moves toward the front of the kitchen cabinet, and then rises along the front side of the upper door piece. Thereby, the lower door piece is transferred to the lower end of the upper door piece to rise along the surface thereof. The inclination with respect to the straight line of the lead is preferably that the inclined portion of the upper guide is larger than the inclined portion of the lower guide. Thereby, the upper end of the lower door piece is moved to the front of the kitchen cabinet more than the lower end, and can be smoothly transferred to the lower end of the upper door piece. In the foregoing upper guide member or lower guide member, when the horizontal distance from the stop position of the upper side guided portion or the lower side Q guided portion to the straight portion is the pull-out width, the pull-out width of the upper guide member is lower than that of the lower guide member The width of the pull-open is suitable. Thereby, the lower blade is pulled up with its upper end pulled out more inclined. Therefore, it is possible to ensure the expansion to the maximum space on the user's head, and it is possible to prevent a feeling of pressure due to the lower door piece. Further, it is also possible to configure a traction portion that pulls the lower door piece and raises it, and the lower door piece is lowered by its own weight by releasing the traction by the traction portion. In consideration of the use of a motor, a gear, or the like, the above-described rail guide and the structure of the guided portion can be lifted and lowered by the upward traction and the use of the deadweight -8 - 200927026. The simplification of the drive mechanism. The traction portion may be formed by a pulley and a cable body that suspends the lifting frame and the lower door piece at both ends via a pulley, and the lower door piece is pulled by the load when the lifting frame is lowered. Thereby, since the lifting frame and the lower door piece are mechanically interlocked, the driving force for raising and lowering the lower door piece can be supplied by the driving source of the lifting frame. [Effect of the Invention] According to the present invention, it is possible to provide a lift cabinet which can reduce the stroke of the descending crane and increase the volume while keeping the pressure feeling with the operation of the door to a minimum. [Embodiment] [Best Mode for Carrying Out the Invention] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. In the detailed description and the drawings, the components that have the same functional structure are denoted by the same reference numerals, and the repeated description is omitted. Further, the dimensions, materials, other specific numbers, and the like shown in the following embodiments are merely examples for facilitating the understanding of the present invention, and are not intended to limit the present invention, particularly in the case of a prior setting. In the present embodiment, the lifting frame of the kitchen lift cabinet (hereinafter referred to as "ceiling cabinet") is interlocked with the lower door piece on the front side of the closing crane to move the two devices toward each other in the reverse direction. Therefore, although the descending stroke of the -9-200927026 frame is not lengthened, the open space in front can be sufficiently ensured. Further, the lower door piece has a feature that it is transferred to the lower end of the upper door piece as it rises and rises along the surface thereof. Here, in order to facilitate the understanding of the present embodiment, first, the arrangement and driving mechanism of the wall cabinet will be described, and the features of the embodiment will be described in detail. Fig. 1 is a perspective view showing the positional relationship between the system kitchenware and the wall cabinet of the embodiment. The system kitchenware 100 is centered on the fire (heating) or water required for conditioning, and the conditioning apparatus is disposed in each storage container in accordance with its size. Although the cabinet 110 is disposed above the system kitchenware 100, the door cannot be opened and closed, and the storage portion is lowered to the height of the eyes of the kitchenware user, and the hand is extended to the front to accommodate or take out the stored object. The system kitchenware 100 is composed of three parts of the water tank 130, the conditioning space 140, and the furnace 150. Among the system kitchen utensils, the wall cabinet 110 is fixedly supported by the wall 500 above the area corresponding to the width of the water tank 130 and the conditioning space 140. On the other hand, above the oven 150 for treating the flame, adjacent to the wall cabinet 110, the range hood 160 is fixedly supported by the wall 500 in the same manner as the wall cabinet. The wall cabinet 1 10 includes a kitchen cabinet 107 that is open below, and a lifting frame 180 that moves up and down the kitchen cabinet 170 toward the inside and outside of the kitchen cabinet 170. The lift frame 1 80 has a storage portion, and most of the front portion is open to allow for the contents of the food container or the kitchen. Further, a front door piece 172 and a lower door piece 174 are disposed in front of the kitchen cabinet 170. When the lifting frame 180 is lowered below the kitchen cabinet 170, the lower door piece 174 moves upward together with the lower door piece 174. Therefore, the upper end of the-10-200927026 of the lifting frame 180 is lowered more than the lower end of the kitchen cabinet 170, and the opening front of the lifting frame 丨8〇 appears in front of the user's eyes. With such a configuration, the movable range of the lift frame 180 can be narrowed, the time for lifting and lowering can be shortened, or the size of the height of the cabinet 11 can be increased to increase the volume. Hereinafter, a description will be given of a drive mechanism for causing the lift frame 180 to interlock with the lower door piece 174. (Drive Mechanism of Lift Frame) Fig. 2 is a view showing a drive mechanism of the lift frame 180. Here, the lifting operation of the lifting frame 180 is mainly explained, and the front side of the hanging cabinet 11 is observed. Further, for the sake of easy understanding, the illustration of the lower door piece 174 is omitted in Fig. 2. First, the two wide cable bodies 200 are wound from the drive pulley 192 in the horizontal direction by the rotation of the drive motor 190. The wide cable body 200 is steered in a vertical direction by a diverting pulley 210 fixedly disposed near the side plates of the kitchen cabinet 170 as a fixed pulley, and the winding ends are respectively fixed to the lifting frame 180. The lifting pulley 212, which functions as a movable pulley, is fixed above the kitchen cabinet 170. Therefore, the lifting and lowering of the crane frame 180 can be performed by rotationally driving the driving motor 190. Here, the cable body is not limited to the rope 'and includes the belt body. As a result, if the lifting frame 180 is lowered, the accommodating portion 220 appears from the back surface of the lower door piece 174 (not shown). (Drive mechanism of the lower door piece) Fig. 3 is a view showing a drive mechanism (traction portion) of -11 - 200927026 of the lower door piece 174 which is interlocked with the lift frame 180. Such a third view is to view the cabinet 110 from the side. Here, the lower door piece 174 is further moved up and down in conjunction with the lift frame 180 shown in Fig. 2 . Fig. 3(a) shows the state in which the crane 18 is housed in the cabinet 17〇. A lower door pulley 250, which is a fixed pulley, is fixedly disposed between the lift frame 180 and the lower door i 74. The lower door piece is connected to the two reels (the first reel 252 and the second reel 254) by a pulley 25, and the shafts are equally rotatably and rotatably supported. Further, the first wire body 260 that suspends the crane frame 180 is wound around the first reel 252, and the second wire body 262 that suspends the lower door piece 174 is wound around the second reel 254. Here, since the first cable body 260 and the second cable body 262 that respectively suspend the lift frame 180 and the lower door piece 174 are mutually reversely wound with respect to the reel, "once the lift frame 180 or the lower door piece 1 If one of the 74s rises, the other will move together and fall because of its own weight. Fig. 3(b) shows a state in which the crane 180 is taken out (dropped) from the cabinet 170. When the lift frame 180 is guided by the guide rail 264 and descends, the first cable body 260 pulls the first spool 252, and the second spool 254 coupled to the first spool 252 rotates only the first spool 252 around the rotation shaft 256. The same amount of angle. Then, the connecting portion 26 6 and the lower door piece 174 which are connected to the second cable body 262 are raised by the winding tension of the second reel 254. Therefore, since the lower door piece 174 rises in accordance with the lowering of the lift frame 180, the sum of the movement amounts becomes the open space of the lift frame 180, so that the opening of the front face of the lift frame 180 can be sufficiently ensured without lengthening the downward stroke. space. At this time, since the load of the lift frame 180 and the lower door piece 174 is biased against each other about the rotation -12-200927026 axis 256, the tensions for rotating the first reel 252 and the second reel 254 are offset each other. It is possible to reduce the load that moves and maintains the lift frame 18〇 and the lower door piece 174 at an arbitrary position, thereby achieving power saving and cost reduction. Further, if the pulley 250 for the door piece is taken down in Fig. 3, it will be understood that the diameters of the winding portions of the first reel 2 52 and the second reel 25 4 are not the same. With such a configuration, the lift stroke ratio of the lift frame 180 and the lower door piece 174 can be arbitrarily set in accordance with the use of the wall cabinet 110. In particular, in Fig. 3, the diameter of the second reel 254 around which the cable body of the lower door piece 174 is wound is smaller than the diameter of the first reel 252 around which the cable body of the suspension frame 180 is wound. As shown in Fig. 3, the cabinet 1 1〇 is assumed to have a certain amount of space that can be occupied below, and is not provided above. Therefore, although the lifting frame 180 can lower its height H1, it can only rise about half the length H2 of the lifting frame until the lower door piece overlaps the upper door piece. The ratio of the diameter of the second reel 254 corresponding to the lower door piece 174 to the diameter of the first reel 252 corresponding to the lift frame can be, for example, H2/Hi, Hi=450 mm, and H2=200 mm. The ratio is 4/9. In this manner, the diameter of the second reel 254 is smaller than that of the first reel 252, and the above-described stroke difference can be realized without using another special mechanism. (Interlocking from the drive motor) As described above, the lift frame 180 is lifted and lowered with the drive motor 190 as a power source, and the lower door piece is lifted by the lift frame 180 as an indirect power source. With such a configuration, the lifting and lowering of both the lift frame 180 and the lower door piece 174 can be controlled by one power source (drive motor). Fig. 4 is an explanatory view showing a comparison of a drive mechanism using the drive motor 190 and a drive mechanism using the lift frame 180. Here, the mechanism for transmitting power to the lift frame 180 by the drive motor 190 is independent of the mechanism for transmitting power to the lower door piece 174 by the lift frame 180, and the direction of transmission of each power can be restricted to the surface direction. For example, since the mechanism for transmitting power to the crane 180 by the drive motor 190 can only be achieved by the steering on the YZ plane, the communication mechanism can be realized by the combination of the cable body and the pulley. Similarly, the mechanism for transmitting power to the lower door 174 by the lift frame 180 can only be achieved by the combination of the cable body and the pulley on the ZX surface. With the above configuration, the lower door piece 174 can be pulled upward by the load at the time of the lowering of the lift frame 180. Since the lifting frame 180 and the lower door piece 174 are mechanically interlocked as described above, the driving force for raising and lowering the lower door piece 1 74 can be supplied by the driving source of the lifting frame 180. Further, since the lower door piece 174 cannot directly receive the power from the drive motor 190, the lower door piece 1 74 is stopped in conjunction with the case where the lift frame 180 cannot be lifted or lowered due to any accident. Therefore, instead of the lift frame 180, only the lower door piece 174 will act, and no secondary damage will occur. (Guiding mechanism of the lower door piece) Next, the guiding mechanism and operation of the lower door piece will be described. Fig. 5 is a view for explaining the guiding mechanism of the lower door piece. Fig. 5(a) is an exploded view showing the guiding mechanism. On the back sides of the side edges of the lower door pieces 174 - 14 - 200927026, a door drive unit 176 for attaching the lower door piece 174 is attached to the joint portion 266, respectively. The connecting portion 266 is provided with an upper roller 268 belonging to the upper guided portion and a lower roller 270 belonging to the lower guided portion. Further, a hanging portion 272 for attaching the second cable body 262 is provided at the upper end of the coupling portion 266. Guide assemblies 280 are provided on each of the side walls of the cabinet 170. The guide member 280 is provided with an upper guide 282 for guiding the upper roller 268 and a lower guide 284 for guiding the lower roller 270. Further, the guide member 280 is provided with a housing mechanism 390 which will be described later. Large diameter portions 2 82a and 2 84a are formed at the lower ends of the upper guide 282 and the lower guide 2 84, respectively, and the heads of the upper roller 268 and the lower roller 270 can be inserted. Further, each of the guide members is provided with the inclined portions 282b, 284b which are moved upward from the stop position (substantially lower end position) of the upper roller 268 or the lower roller 270, and are guided toward the front of the kitchen cabinet 170, and are connected to The inclined portions 282b and 284b are substantially straight portions 282c and 284c that are guided in the vertical direction. The upper guide 282 and the lower guide 284 are formed in the above shape, so that as the lower door 174 moves upward, the lower door 174 moves to the front of the kitchen cabinet by the inclined portions 282b and 284b, and then the straight portion 282c and 284c rise along the front side of the upper door piece 1 72. Thereby, the lower door piece 1 74 is transferred to the lower end of the upper door piece 172 to rise along the surface thereof. Fig. 5(b) is an assembled view of the guiding mechanism. The upper roller 268 and the lower roller 270 are slidably fitted to the upper guide 282 and the lower guide 284. The second wire body 2 62 is attached to the hanging portion 272 of the joint portion 266, whereby the lower door piece 1 74 is stopped. From the stop position, the second cable body pulls the connecting portion 266 upward, whereby the upper roller 268 and the lower roller 270 -15-200927026 are guided by the upper guide 282 and the lower guide 284, while the lower door 174 is guided. Will rise. Fig. 6 is a view for explaining the operation of the lower door piece, and the operation of the lower door piece will be described with reference to the shape of the guide member of Fig. 5(b). Fig. 6(a) shows the state in the stop position. From this state, the second cable body 262 is pulled, whereby the lower door piece 174 starts to operate. At this time, as shown in Fig. 5(b), the inclination with respect to the straight line of the lead is that the inclined portion 2 8 2 b of the upper guide 282 is larger than the inclined portion 2 8 4 b of the lower guide 2 8 4 . Thereby, as shown in Fig. 6(b), the upper end of the lower door piece 174 starts moving toward the front of the kitchen cabinet more than the lower end. Further, as shown in Fig. 6(c), when the upper end of the lower door piece 174 is moved forward more than the lower end of the upper door piece 172, up to the upper roller 268 and the lower roller 270 to the straight portions 282c, 284c, such as As shown in Figure 6(d), it starts to rise. When the upper ends of the straight portions 282c and 284c are raised, as shown in Fig. 6(e), the upper side of the lower door piece 174 and the lower side of the upper door piece 172 are overlapped. Fig. 7 is a view for explaining the locus of the lower door piece 174, the joint portion 266, the upper roller 268, and the lower roller 270. Referring to Fig. 7, it is understood that the upper end of the lower door piece 174 is transferred to the lower end of the upper door piece 172, and the lower door piece 174 is raised along the surface of the upper piece 172. After the upper roller 268 and the lower roller 270 reach the straight portions 282c and 284c, the posture (inclination angle) of the lower door piece 174 is kept constant. Here, as shown in Fig. 5(b), the horizontal distance from the stop position of the roller 268 above the upper guide 282 to the straight portion 282c is the pull-out width wi, and the stop of the roller 270 from the lower guide 284. The horizontal distance from the position to the straight portion 284c is -16, 2009,270,26, which is the width w2. Further, in the present embodiment, the pull-out width w1 of the upper guide is set longer than the pull-out width W2 of the lower guide. Thereby, the lower door piece 174 is raised while the upper end is pulled out more and pulled to the front of the kitchen cabinet, and the posture is maintained during the stop period. By this, it is possible to ensure that the user's head is enlarged to the maximum space and that it is protected from the pressure of the lower door piece. When the lower door piece 174 is closed, that is, when the lifting frame 180 is raised, the lower door piece 174 is reversed by the rising process shown in Fig. 6, and is housed below the upper door piece 172. At this time, by the action of the housing mechanism 390, it is finally closed. The structure and operation of the housing mechanism 3 90 will be described. As shown in Fig. 5(a), the housing mechanism 3 90 is provided with an arm 390a that is provided at an upper portion of the guide unit 280 and that is rotatably supported by the intermediate portion at the guide unit 280, and one end of the arm. The roller 390b and the spring 3 90c (pushing means) for pushing the roller 3 90b toward the inside of the cabinet. On the other hand, the connecting portion 266 is provided with a housing guide 266a for moving the roller 39 0b of the housing mechanism 390. The accommodating guide 266a has a groove shape of a C-shaped cross section, and the roller 3 90b abuts against the side wall thereof, whereby the elastic connecting portion 266 can be pushed toward the inner side of the cabinet. When the lower door piece 174 is raised as described above, as shown in Fig. 6, since the roller 390b abuts against the side wall of the accommodating guide 266a, the accommodating mechanism 390 is rotated against the urging force of the spring 390c. Further, when the upper roller 268 and the lower roller 270 are in the straight portion, since the pushing force of the housing mechanism 3 90 is substantially orthogonal to the direction of the guide groove, there is no -17-200927026 妨碍 which hinders the lifting force. Further, when the lower door piece 174 is closed, in particular, when the upper roller 268 and the lower roller 270 are positioned at the inclined portions 282b and 284b, the spring force of the spring 390c of the housing mechanism 3 90 acts on the direction in which the lower door piece 174 is accommodated. Here, it is assumed that since the lower door piece 174 is closed only by its own weight, and the upper roller 268 and the lower roller 270 are formed in the inclined portions 282b and 284b, the force in the direction of accommodation is weakened. Therefore, the lower door piece 1 74 is not closed at the end, and the movement of the U is completed when the upper door piece 172 is slightly floated. However, since the housing mechanism 390 having the above-described structure is provided, the upper end of the coupling portion 266 is particularly pushed toward the inside of the cabinet 170, so that the lower door piece 174 can be reliably received under the upper door piece 172. As described above, the wall cabinet 110 of the present embodiment can sufficiently ensure the front open space without lengthening the lowering stroke of the lift frame 180, shortening the stroke of the lower lift frame, and increasing the volume. In addition, the lower door piece will be transferred to the lower end of the upper door piece and raised along the surface thereof, thereby being able to lift the kitchen Q-lifting wall cabinet with the pressure of the door action being kept to a minimum. Easy to use. Hereinabove, the description has been made with reference to the drawings and the preferred embodiments of the invention, but the invention is of course not limited to such examples. It will of course be within the technical scope of the present invention to be able to recognize various modifications or alterations within the scope of the invention as described in the appended claims. [Industrial Applicability] The present invention can be utilized as a lift hanger -18 - 200927026 cabinet provided above the kitchenware.
