200905055 九、發明說明 【發明所屬之技術領域】 本發明是關於具備可裝卸自如設置在圓筒或圓柱的外 圍面圓周方向形成有溝槽的支柱上之構造的掛鈎。 【先前技術】 一般，衣類或鞋子等鈎掛用的掛鈎，使用方式大多是 在室內牆或柱等安裝掛鈎的位置決定後，用螺絲或釘子加 以固定。然而，上述掛鈎’安裝時較花費工時，同時使用 位置受限’ 一旦固定在安裝位置，若要移往他處也較花費 工時。此外，不使用時還是會突出於牆或柱，因此有妨礙 通行等問題點。 於是’例如下述專利文獻1所示，提案有可根據需求 使用裝卸自如的掛鈎。 該掛鈎是由懸掛具本體和鎖緊環所構成，懸掛具本體 以一條彈性線形成有：隔著彈性部形成在連結部兩端的懸 掛部；從該懸掛部延伸出來的直線部；形成在該直線部前 端的夾持部；從該夾持部一方垂下的垂下部；形成在該垂 下部前端的圓弧部；及從上述夾持部另一方延伸出來可和 上述圓弧部彼此重疊的鎖緊部，此外，鎖緊環是插入在上 述直線部透過移動可使上述夾持部的間隔縮窄。 上述懸掛具是在上述鎖緊部和上述圓弧部成開放的狀 態下’將上述鎖緊部配位在棚架或柱等的支柱背側，將上 述圓弧部配置在前側，將上述鎖緊環於上述支柱側移動在 -4- 200905055 上述直線部，藉此使上述夾持部夾持著上述支柱兩側的同 時’使上述η弧部壓接固定在上述支柱。 另一方面’組裝式的棚架，已知是由：金屬製在外圍 面圓周方向設有溝槽的支柱；四角隅設有嵌合管的長方形 或正方形棚板；及上述棚板支撐用的棚板固定零件所構 成’構成爲從上述支柱上部的上述棚板固定零件套在所希 望的任意位置’然後將棚板從該棚板固定零件上套著上述 棚板固定零件。上述組裝式的棚架，能夠容易組裝成適合 家庭內使用的尺寸，此外可變更組裝因此需求性高。 然而’當將專利文獻1記載的懸掛具安裝在上述組裝 式棚架的支柱時’該懸掛具是壓接固定在上述支柱，因此 爲了不讓對象物掉落而強化壓接力進行安裝時懸掛具就會 被固定無法移動’使對象物掛持用的臂部方向受到限定。 此外’反之若要讓臂部朝向成爲不被固定的程度而調整壓 接力時，則掛吊較重的對象物時整個掛鈎就會掉落。 再加上’上述臂部具備有夾持在上述柱時使用的上述 鎖緊環’當打開上述臂部的上述夾持部側而安裝在上述支 柱時，需要將上述鎖緊環退至上述懸掛部側，因此上述臂 部若不形成較長’則無法打開上述夾持部側。基於此，使 用時上述臂部就會從上述支柱朝外方突出較多，有較占據 空間造成妨礙等問題點。 [專利文獻1 ]日本實開平4 - 1 1 5 4 7 6號公報 【發明內容】 -5- 200905055 本發明是以提供一種安裝在上述組裝式棚架的支柱 時’可朝圓周方向轉動，並且在掛有較重對象物時也不會 掉落’再加上使用時不會造成妨礙的掛鈎爲課題。 [本發明的第1形態] 爲解決上述課題，本發明第1形態相關的掛鈎，是一 種可裝卸自如設置在外圍面形成有延伸在圓周方向之溝槽 的圓筒狀或圓柱狀支柱做爲對象物掛持用的掛鈎，其特徵 爲’具備：圍繞在上述支柱外圍朝圓周方向轉動自如的本 體；及連結於上述本體構成爲可掛持上述對象物的鈎掛 部，上述本體具有他端部彼此連結形成爲可使一端部間開 閉自如的同時，內圍面沿著上述支柱外圍面形成圓弧狀的 一對第1及第2本體，於該等上述第1及第2本體至少一 方的上述一端部側連結有上述鈎掛部的同時，於上述第1 及第2本體至少一方的上述內圍面形成有卡合於上述支柱 槽部可阻止上述本體朝軸線方向移動的突出部。 上述掛鈎中，上述鈎掛部可形成爲鈎狀。 此外，於上述掛鈎中，上述本體和上述鈎掛部兩者連 結用的連結部，可構成爲具有：分別從上述第1及第2本 體的上述一端部朝徑方向突出的同時，於安裝在上述支柱 成互相連結時全體是朝軸線方向形成反u字型的第1及 第2凸部；及形成在和形成上述鈎掛部的上述鈎狀的部份 成相反側的背面部可插入上述第1及第2凸部的反u字 型凹部，此外是構成於上述第1及第2凸部設有延伸在上 200905055 述軸線方向的窄縫的同時’於上述凹部設有可嵌合於上述 窄縫的凸部。 根據本發明的第1形態時’本體是安裝在支柱外圍可 朝圓周方向3 6 0度轉動自如’因此將上述本體相對於支柱 轉動，就能夠透過每次轉動改變對象物掛持用鈎掛部的位 置或朝向。此外，上述本體和對象物掛持用的上述鈎掛部 是構成爲可連結，因此上述鈎掛部可根據用途換成各種不 同的形狀。再加上，上述支柱的溝槽部和形成在上述本體 內圍面的突出部是形成卡合著，因此即使鈎掛部掛持有較 重的對象物但整個掛鈎還是不會掉落。 另外，鈎掛部是形成爲鈎狀，因此能夠簡單鈎掛對象 物，並且能夠使對象物不滑落或因碰撞而脫落。再加上， 藉由將上述鈎掛部形成爲鈎狀，能夠縮短從上述支柱突往 外方的長度，能夠避免造成妨礙或造成使用者碰撞導致使 用者受傷。 又加上，連結部是從上述一端部朝徑方向突出，軸線 方向呈反U字型的凸部卡合著形成在上述鈎掛部背面部 呈反u字型的凹部，藉此使成爲上述第1及第2本體開 閉自如的上述一端部間能夠確實固定的同時，能夠防止掛 鈎上述軸線方向的脫落。此外，於設置在呈上述反U字 型上述凸部的窄縫，嵌合被設置在上述鈎掛部呈上述反U 字型上述凹部內的突部，因此能夠防止掛鈎朝徑方向外方 脫落。再加上’於上述鈎掛部掛持有對象物時，對象物的 重量會強化固定，使掛鈎更加牢固。 -7- 200905055 另’第1凸部及第2凸邰，如上述，在第1本體和第 2本體關閉時’全體也是可形成軸線方向呈反u字型，即 形成只有凸部上端部呈半圓弧形，但也可形成爲凸部的上 端部和下端部雙方呈半圓弧形。 [本發明的第2形態] 本發明第2形態相關的掛鈎是一種可裝卸自如設置在 外圍面形成有延伸在圓周方向之溝槽的圓筒狀或圓柱狀支 柱做爲對象物掛持用的掛鈎，其特徵爲，具備：圍繞在上 述支柱外圍朝圓周方向轉動自如的本體；及於該上述本體 成一體設置，從上述支柱突出在外方可掛持上述對象物的 臂部，上述本體具有他端部彼此連結形成可使一端部間開 閉自如地的同時，內圍面沿著上述支柱外圍面形成圓弧狀 的一對第1及第2本體，該等上述第1及第2本體至少一 方成一體設有上述臂部的同時，設有裝卸自如可使上述第 1及第2本體的上述一端部彼此連接成關閉狀態的連結構 件，並且於上述第1及第2本體至少一方的上述內圍面， 形成有卡合於上述支柱溝槽部可阻止該本體朝軸線方向移 動的突出部。 上述掛鈎中，上述臂部，例如：具有設置在上述本體 的第1分割臂部，及設置在上述第2本體的第2分割臂 部，並且該等上述第1及第2分割臂部，於上述第1及第 2本體關閉狀態是互相抵接形成爲呈圓筒狀或圓柱狀的同 時，上述連結構件是一種筒狀連結具，於中心部穿通設有 -8 - 200905055 上述臂部插入用的孔部。 再加上，於上述第1分割臂部及第2分割臂部至少一 方的外圍面，設有具撓性可出沒自如於該外圍面的凸部， 並且於上述連結具穿通設有可卡合著上述凸部藉此防止該 連結部脫落的孔部。 該狀況時，上述凸部的外表尺寸，最好是形成比上述 孔部的內徑還大。 根據本發明的第2形態時，上述本體是安裝在支柱外 圍可朝圓周方向360度轉動自如，因此將上述本體相對於 支柱轉動就能夠透過每次轉動改變對象物鈎掛用臂部的位 置或朝向。此外’上述支柱的溝槽部和形成在上述本體內 圍面的突出部是形成卡合著，因此即使對上述臂部吊掛較 重的對象物但整個掛鈎還是不會掉落。 此外’將穿通設有孔部的筒狀上述連結具插入在形成 爲圓筒狀或圓柱狀的上述臂部，可使上述臂部和上述連結 具成爲一體，因此能夠確實固定上述本體關閉狀態中的上 述臂部的連結，同時透過上述連結具和上述臂部成爲一體 可增加強度，使掛鈎更爲牢固。 另外’上述臂部的外圍面設有具撓性的凸部，並且上 述連結具穿通設有上述凸部卡合用的孔部，因此朝上述臂 部插入上述連結具時，能夠讓上述凸部和孔部嵌合防止上 述連結具脫落。 此時，若上述凸部的外表尺寸是形成比上述孔部內徑 還小時，則上述凸部外表尺寸和上述孔部內徑之間會產生 -9- 200905055 間隙恐怕造成固定強度變弱。另一方面，若上述凸部的外 表尺寸是設定成上述孔部內徑的最大孔尺寸時，則上述凸 部和孔部會形成牢固卡合強化固定，但反之要裝卸時就難 以拆卸。 關於這點，根據本發明的第2形態時，上述凸部的外 表尺寸是形成比上述孔部內徑還大，因此上述凸部外表尺 寸和上述孔部內徑之間不會產生間隙。此外，上述凸部具 有撓性，於上述孔部內徑能夠不產生間隙地卡合著上述凸 部部份，因此上述孔部和上述凸部是彼此嵌合成不脫落程 度。反之’因上述凸部具有撓性，於裝卸時上述凸部部份 會撓曲’形成和上述孔部部份彼此爲輕狀態卡合所以就容 易裝卸。因此，當從上述臂部裝卸上述連結具時，就能夠 簡單進行裝卸。 【實施方式】 [發明之最佳實施形態] [第1實施形態] 第1圖至第6圖是表示本發明掛鈎的第1實施形態。 該掛鈎是以本體1圍繞在支柱2 0，將鈎掛部6連結在本 體1藉此形成安裝在支柱2〇的安裝構造。 如第6圖所示，支柱20是圓筒狀或圓柱狀，於長度 方向各隔著等間隔形成有延伸在外圍面圓周方向的複數溝 槽21。 安裝在該支柱20加以使用的上述掛鈎，如第1圖至 -10- 200905055 第5圖所示’是由：沿著支柱20外圍面形成其內圍面和 支柱20外徑尺寸相同或半徑比支柱2〇還稍微大的圓弧面 本體i ;及連結設虞在本體1從支柱2〇突出在外方可掛 持對象物的鈎掛部6所構成。 接著，本體1，如第2A圖所示，是由一對第1本體 la及第2本體lb所構成。該第1本體h及第2本體lb 在他端部1 〇間連結成可使一端部9間開閉自如。即，本 體1是將突出設置在第1本體la的他端部的插銷部 12嵌合於穿通設置在第2本體1b他端部10的孔部’藉 此使第1本體la及第2本體1b形成爲一體並且轉動自 如。 再加上，第1本體la及第2本體lb的內圍面中央 部，形成有沿著圓弧面成線狀的突出部8。此外，該突出 部8，其高度尺寸是形成可.嵌入於形成在支柱20的溝槽 21。另，第1本體la的突出部8是相對於圓弧面中心形 成在1〇5度的角度範圍。此外，第2本體lb的突出部8 是相對於圓弧面中心形成在7 0度的角度範圍。 另外’如第2 B圖所示’於成爲開閉自如的一端部9 側，在第1本體la形成有第1凸部2a，在第2本體lb 形成有第2凸部2b。該第丨凸部2a及第2凸部2b，於第 1本體1 a和第2本體丨b關閉時，整體是形成朝軸線方向 呈反U字形狀。再加上，於凸部2 ’在第丨本體1 &的第i 凸部2a和第2本體lb的第2凸部2b之貼合面相反側的 側面’分別形成有延伸在軸線方向的窄縫4。 -11 - 200905055 另一方面’鈎掛部6是和本體1連結，形成爲朝本體 1外方突出的鈎狀。此外，如第3 B圖所示，於鈎掛部6， 在形成鈎狀部份其相反側的背面部6 a的軸線方向，形成 有呈反U字型的凹部7。再加上，如第3A圖所示，於凹 部7形成有突部7 a，該突部7 a是形成爲凹部7相向的內 壁可卡合於形成在本體1的凸部2的窄縫4。 將以上構成的掛鈎安裝在支柱2 0加以使用時，首先 是如第5圖所示，先將形成在本體1的第1本體la及第 2本體lb —方內圍面的突出部8，插入形成在支柱20的 溝槽2 1內，將另一方從支柱2 0的另一側夾入形成關閉。 接著，如1圖所示，將形成在鈎掛部6的形成鈎狀部 份相反側背面部6 a的凹部7，從本體1的凸部2的上面3 往下滑動的同時卡合於形成在該第1本體1 a和第2本體 1 b —端部9側的凸部2。 此時，於形成在第1本體la及第2本體lb的第1凸 部2a及第2凸部2b其分別設有的窄縫4，會嵌合著鈎掛 部6的形成鈎狀的部份和形成在其相反側背面部6 a的凹 部7內設有的突部7a，使第1本體la及第2本體lb的 一端部9側確實固定。 根據第1實施形態的掛钩時，本體1是安裝在支柱 20外圍可朝圓周方向360度轉動自如，因此將本體1相 對於支柱2 0轉動’就能夠透過每次轉動改變對象物掛持 用鈎掛部6的位置或朝向。此外，本體1和對象物掛持用 的鈎掛部6是構成可連結，因此鈎掛部6可根據用途換成 -12- 200905055 各種不同的形狀。再加上，支柱20的溝槽部21和形成在 本體1內圍面的突出部8是形成卡合著，因此即使鈎掛部 6掛持有較重的對象物但整個掛鈎還是不會掉落。 另外，鈎掛部6是形成爲鈎狀，因此能夠簡單鈎掛對 象物，並且能夠使對象物不滑落或因碰撞而脫落。再加 上，藉由將鈎掛部6形成爲鈎狀，能夠縮短從支柱2 0突 出外方的長度，能夠避免造成妨礙或造成使用者碰撞導致 使用者受傷。 又加上，連結部1 1是從上述一端部9朝徑方向突 出，軸線方向呈反U字型的凸部2卡合著形成在鈎掛部6 背面部6 a呈反U字型的凹部7，藉此使成爲第1及第2 本體 1 a、1 b開閉自如的一端部 9間能夠確實固定的同 時，能夠防止掛鈎上述軸線方向的脫落。此外，於設置在 呈上述反U字型凸部2的窄縫4，嵌合被設置在鈎掛部6 呈上述反U字型凹部7內的突部7a，因此能夠防止掛鈎 朝徑方向外方脫落。再加上，於鈎掛部6掛持有對象物 時，對象物的重量會強化固定，使掛鈎更加牢固。 再加上，只要支柱20爲圓筒狀或圓柱狀，並且於外 圍面圓周方向形成有溝槽部2 1 ’就能夠根據需求於使用 時再安裝掛鈎。此時，在使用該掛鈎時，只要進行簡單的 作業即先將本體1夾著支柱20形成關閉，接著將鈎掛部 6連結於本體1，如此一來就能夠完成掛鈎安裝。 另，第1實施形態是針對掛鈎採用鈎狀鈎掛部6時的 狀況進行了說明，但並不限於此’例如也可以是水平方向 -13- 200905055 的鈎掛型式。此外’也可應用被稱爲雙鈎的連結構件。另 外’對於連結部1 1，也是只針對卡合形狀爲反u字型的 狀況進行了說明’但並不限於此，例如也可應用在卡合成 U字型形狀的掛鈎。於該狀況時，於本體1形成凹部，於 鈎掛部6形成凸部。 此外，第1實施形態，爲了於第1本體1 a和第2本 體1 b關閉時’讓弟1凸部2 a及第2凸部2 b全體朝軸線 方向呈反U字型，即是形成只有凸部2的上端部成爲半 圓弧形’但也可將凸部2的上端部和下端部雙方成爲半圓 弧形。根據上述構成時，即使本體1的朝向上下相反，還 是能夠將本體1安裝在支柱2 0，使掛鈎的安裝變成更加 容易。 [第2實施形態] 第7圖至第12圖是表示本發明掛鈎的第2實施形 態。該掛鈎是和第1實施形態相同以本體1 04圍繞著支柱 20，將連結具9套在從上述本體1〇4突出外方的臂部108 藉此形成安裝在支柱的安裝構造。 該掛鈎，如第7圖至第12圖所示，是由：沿著上述 支柱20外圍面形成爲其內圍面和上述支柱20外徑尺寸相 同或半徑比該支柱20還稍微大的圓弧面本體104;設置 在該本體104成一體，並且從上述支柱20突出在外方可 吊掛對象物的臂部1 0 8 ;及朝該臂部1 〇 8插入著臂部1 0 8 的筒狀連結具109所構成。 -14- 200905055 接著，上述本體104，如第7圖所示’其是由一對第 1本體102及第2本體103所構成。該第1本體102及第 2本體1 03是他端部間連結成可使一端部間開閉自如。於 該第1本體1 02的他端部，如第7圖、第8圖所示，一體 形成有連結體150。另一方面，於第2本體1〇3的他端 部，如第7圖第9圖所示，一體形成有朝向上述連結體 15〇上下面，從該第2本體103上下面延伸出來成彼此平 行的第2連結片1 5 1。 此外，於該第2連結片1 5 1形成有貫通中心部的軸孔 153。接著，於上述連結體150的上下面，在與該第2連 結片1 5 1成相向的位置，如第8 B圖至8 E圖所示是突出 設有僅嵌入上述軸孔1 5 3深度的突軸1 5 2。 接著’上述本體104’如第7圖所示，構成爲上述第 1本體102的上述突軸152和上述第2本體103的上述軸 孔嵌合形成爲一體轉動自如。 另外’於上述第1本體102的端面，如第8D圖所 示’形成有由1〇個凹部形成的第1凹部130。另一方 面，於上述第2本體103的端面，如第9D圖所示，形成 有由10個凸部形成的第2突起部131。 再加上’於上述桌1本體1〇2及第2本體103的內圍 面中央部，如第7圖、第8B圖、第8C圖、第9A圖、第 9B圖所示，形成有沿著圓弧面成線狀的突出部1 〇5。此 外，該突出部105,其高度尺寸是形成可嵌入於形成在上 述支柱20的上述溝槽20。另，上述第1本體1〇2的突出 -15- 200905055 部1 0 5是相對於圓弧面的中心形成在〗〇 5度的角度範圍。 此外’上述第2本體1 03的突出部1 〇5是相對於圓弧面的 中心形成在70度的角度範圍。 另一方面，上述臂部1〇8，如第7圖所示，由第1分 割臂部1 06和第2分割臂部1 07所構成。上述第〖分割臂 部106是形成從上述第1本體1〇2成一體往外方突出著。 另方面，上述第2分割臂部1〇7是形成爲從上述第2本體 103成一體往外方突出著。該第1分割臂部106及第2分 割臂部1 07，於上述本體1 04的關閉狀態，形成爲互相抵 接整體呈圓筒狀。 再加上，於該第1分割臂部1 〇 6的前端部的相向緣 面，第8B圖、第8C圖、第8E圖所示，形成有突出片 11〇。另一方面，於上述第2分割臂部107的前端部的相 向緣面，第9A圖、第9E圖所示，形成有上述突出片110 卡合用的嵌合孔1 1 1。 此外，於上述第1分割臂部1 〇6的外表面’如第8A 圖至第8C圖所示，形成有將舌狀圓弧部朝向上述第1本 體1 02側藉由往軸方向進刀切入形成具有撓性的第1切邊 片180。另一方面，於上述第2分割臂部107的外表面， 如第9A圖至第9C圖所示，同樣是形成有將舌狀圓弧部 朝向上述第2本體103側藉由往軸方向進刀切入形成具有 撓性的第2切邊片1 8 1。 接著，於該第1切邊片18〇的上面’形成有圓型的第 1凸部182。另一方面，同樣是在上述第2切邊片181的 -16- 200905055 上面，形成有同樣圓型的第2凸部183。另，該第1凸部 182及第2凸部183的外表尺寸，例如爲4φ。 此外’上述連結具109，如第10Α圖、第10Β圖所 不’形成爲中心部穿通設有孔部1 9 6的筒狀，於前端部形 成有可蓋住開口的把柄部1 8 7。接著，該把柄部1 8 7形成 有朝徑方向隆起的隆起部1 8 8。如此一來，當對象物掛在 該連結具1 0 9時，就能夠防止對象物掉落。再加上，上述 連結具109是在其和上述第1切邊片180及第2切邊片 181成相向的部份，分別穿通設有3φ的孔部185。 以上構成的掛鈎，如第1 1圖所示，將形成在上述第 1本體102及第2本體103的一方內圍面的突出部1〇5插 入於形成在上述支柱20的溝槽21內，將另一方從上述支 柱2 0的另一側夾入支柱形成關閉。其次，將分別形成爲 —體設置在該第1本體102和第2本體103的上述第1分 割臂部1 06及第2分割臂部1 07彼此互相抵接。 此時，形成在該第1分割臂部10 6和第2分割臂部 107的前端部相向緣面的上述突出片11〇和上述嵌合孔 111會成爲嵌合，如此一來就形成上述臂部108。 接著，於上述連結具109的上述孔部186內插入上述 臂部108，使形成在該臂部108的上述第1凸部182及上 述第2凸部183分別嵌合著穿通設置在上述連結具109的 上述孔部1 8 5。如此一來，如第1 2圖所示，就可讓上述 連結具109套入至和上述本體104成一體的上述臂部108 基端形成定位。 -17- 200905055 根據第2實施形態的掛鈎時，只要是圓筒狀或圓柱 狀，並且外圍面圓周面形成有溝槽2 1的支柱2 0，就能夠 根據需求在使用時安裝掛鈎。此時，在使用該掛鈎時，只 要進行簡單的作業即先將上述本體1 04夾著上述支柱20 形成關閉，接著將上述連結具1 0 9套入上述臂部1 〇 8 ,如 此一來就能夠完成掛鈎安裝。 此外，將上述連結具109套入上述臂部108，能夠讓 上述臂部108和連結具成爲一體，能夠確實固定上述本體 1 0 4閉狀態中的上述第1分割臂1 0 6和上述第2分割臂 1 07的連結，因此強化固定，使掛鈎更爲牢固。 另外’上述連結具1 0 9形成有隆起部1 8 8，因此在鈎 掛有對象物時能夠防止對象物掉落。 接著，於上述第1分割臂106及上述第2分割臂107 的外圍面，分別設置的上述第1凸部1 8 2及第2凸部1 8 3 會和穿通設置在上述連結具109的上述孔部185形成嵌 合，因此能夠防止上述連結具1 09脫落。 此.外，上述第1切邊片180及第2切邊片181是朝本 體進刀切入成舌狀，因此能夠讓上述第1凸部182及第2 凸部1 8 3和上述孔部1 8 5順利嵌合。 此時，因上述第1凸部182及第2凸部183的外表尺 寸是形成比上述孔部1 8 5內徑還大1 φ，所以上述第1凸 部1 82及第2凸部1 83的外表尺寸和上述孔部1 85的內徑 之間不會產生間隙，因此能夠確實嵌合強化防止上述連結 具1 0 9脫落。 -18- 200905055 再加上，上述第1凸部182及第2凸部183，是由上 述第1切邊片180及第2切邊片181造成能夠撓曲，因此 上述第1凸部182及第2凸部183和上述孔部185是成爲 輕狀態嵌合’能夠簡單進行上述臂部1 〇 8和上述連結具 1 0 9的裝卸。因此’能夠配合上述支柱2 0的上述溝槽2 1 形成位置，簡單移動安裝部位（高度暨位置）。 接著，上述本體104的圓弧面是形成和上述支柱20 的外徑尺寸相同或半徑比支柱20還稍微大，並且上述突 出部1 0 5是沿著圓弧面形成在合計1 7 5度中心角的範圍， 同時其前端是嵌入上述溝槽21。其結果，能夠讓上述本 體1 0 4以3 6 0度旋轉在上述支柱2 0的外圍，因此，能夠 透過每次轉動改變對象物吊掛用上述臂部1 0 8的位置或方 向。此外，透過上述突出部1〇5能夠讓上述本體104和上 述溝槽2 1的磨擦阻力變少’能夠順利旋轉的同時和上述 溝槽2 1卡合著，因此即使掛有較重的對象物，但整個掛 鈎還是不會掉落，能夠穩定使用掛鈎。 另’本實施形態中，對於連結構件是以使用筒狀的上 述連結具1 〇 9爲例子進行了說明，但並不限於此，例如也 可以是水平方向的鈎掛型式。此外，也可應用被稱爲雙鈎 的連結構件。 [產業上之可利用性] 根據本發明時，可提供一種可轉動在組裝式棚架支柱 圓周方向的狀態安裝在支柱，並且在掛有較重對象物時也 -19- 200905055 不會掉落，使用時不會造成妨礙的掛鈎。 【圖式簡單說明】 第1圖爲表示本發明第1實施形態掛鈎透視圖。 第2A圖爲表示第1本體及第2本體構成透視圖。

[Prior Art] In general, hooks for hooks such as clothing and shoes are often used in a position such as an indoor wall or a column to be attached to a hook, and then fixed by screws or nails. However, the above-mentioned hooks are more time-consuming to install and have a limited use position. Once fixed in the installation position, it takes more time to move to another place. In addition, when it is not in use, it will still protrude from the wall or column, so there are problems such as obstruction. Then, for example, as shown in the following Patent Document 1, a hook that can be detachably used as needed is proposed. The hook is composed of a suspension body and a locking ring. The suspension body is formed by an elastic line: a hanging portion formed at both ends of the connecting portion via an elastic portion; a straight portion extending from the hanging portion; a clamping portion at the front end of the straight portion; a hanging portion that is suspended from the clamping portion; a circular arc portion formed at the front end of the hanging portion; and a lock extending from the other of the clamping portion and overlapping the circular arc portion In the tight portion, the locking ring is inserted into the straight portion to transmit the movement of the straight portion to narrow the interval between the nip portions. In the suspension device, the locking portion is placed on the back side of the pillar such as a scaffold or a column in a state where the locking portion and the circular arc portion are open, and the arc portion is disposed on the front side, and the lock is placed. The tight ring is moved to the linear portion of -4-200905055 on the side of the pillar, whereby the sandwiching portion sandwiches both sides of the pillar and simultaneously presses and fixes the n-arc portion to the pillar. On the other hand, the 'assembled scaffold is known to be: a metal pillar having a groove in the circumferential direction of the outer peripheral surface; a rectangular or square slab having a fitting tube at the four corners; and the support for the slab support The shed fixing member is configured to "seat the slat fixing member from the upper portion of the struts at a desired arbitrary position" and then slid the slat from the slat fixing member to the shed fixing member. The above-described assembled scaffold can be easily assembled into a size suitable for use in a home, and the assembly can be changed, so that the demand is high. However, when the hanger according to Patent Document 1 is attached to the pillar of the assembled scaffold, the hanger is crimped and fixed to the pillar. Therefore, the hanger is installed in order to prevent the object from falling and to increase the crimping force. It will be fixed and cannot move. The direction of the arm for holding the object is limited. Further, on the other hand, if the pressing force is adjusted so that the arm portion is not fixed, the entire hook will be dropped when the heavier object is hung. Further, when the arm portion is provided with the lock ring that is used when the column is clamped, when the arm portion is opened and attached to the support portion, the lock ring needs to be retracted to the suspension. If the arm portion is not formed long, the above-mentioned arm portion cannot be opened. Based on this, when the arm is used, the arm portion protrudes from the above-mentioned strut to the outside, and there is a problem that the occupied space is obstructed.

Then, the circular arc surface of the main body 104 is formed to have the same outer diameter as the pillar 20 or the radius is slightly larger than the pillar 20, and the protruding portion 105 is formed along the circular arc surface at a total center of 175 degrees. The range of angles, while the front end is embedded in the above-mentioned groove 21. As a result, the body 104 can be rotated around the outer periphery of the column 20 at 370 degrees. Therefore, the position or direction of the arm portion 108 can be changed by each rotation. Further, the protruding portion 1〇5 can reduce the frictional resistance of the main body 104 and the groove 21, and can smoothly rotate and engage with the groove 21, so that even a heavy object is hung. However, the entire hook will not fall, and the hook can be used stably. In the present embodiment, the connecting member is described as an example in which the connecting member 1 〇 9 is used in a tubular shape. However, the present invention is not limited thereto, and may be, for example, a hooking type in the horizontal direction. Further, a joint member called a double hook can also be applied. [Industrial Applicability] According to the present invention, it is possible to provide a rotatably mounted pillar in a state in the circumferential direction of the assembled scaffold pillar, and also to hang on a heavier object -19-200905055 , hooks that do not cause obstruction when used.
