1342272 九、發明說明: 【發明所屬之技術領域】 本發明係有關於一用於家具及類似物之移動件之自行定 向腳輪。 【先前技術】 自行定向腳輪,尤指所謂之雙輪型式,係屬習知者,其 由兩輪子所構成,而該等輪子被裝設成使其可繞—轴而轉 動。該軸被支揮於-座中,該座係形成於—位於該等輪子 間之支撑結構上,且通常包括一半圓柱狀殼體之型式而 該位於一上部區域中之殼體覆蓋住該等輪子。 一直立之圓柱狀凹處被成形於該支撐結構中,並向上敞 =相對於該轴呈轴向偏置,該凹處亦作為該腳輪之該用
疋向(梅轉)之_直立抱軸的一旋轉座,而該抱轴被設 计成可插入並保持於一欲裝置該輪子於其上 座内。 J 式之自行定向腳輪具有下列缺失,即用於自行定 經常導致過度及令人不悅之噪音,尤其當 件、粗㈣面時’或如果想要接納該框轴之該 件豕具之座破成形於一金屬體内 生在其上設置一具有諸徑向臂 :战察付知此尤發 上,其中該等腳輪被裝設在該4=椅子或扶手精 托架之個別凹處中之柜轴存在不可=:。由於位在該 餘ΙΨ m A # m 人 f避免的餘隙,而在當該 餘隱因為使用而傾向於不可避免地增加時, 在新腳輪上之缺失亦隨之變得嚴重。 9697I.doc 1342272
【發明内容】 本發明之目標在於藉由提俾— ^ 簡单且有效之解決方法而 4除上述習知自行定向腳輪 ^ L 缺失’其並不需要對現有市 面上可購得之腳輪作實質之結 β 。毒支更’因而在經濟效益上 疋具有優點的0 此一目標可藉一種自行定向 ±Α 胃輪而達成,該自行定向腳 輪由至少一輪子構成,該輪子 J轉動於一軸上,該軸經由 一支撐結構之座而被水平地驅動,該支撐結構設有-直立 圓柱狀凹處,其向上敞開且相對於該心㈣偏置,且盆 中-用於樞轉該腳輪之柜軸可與—第一部分一起轉動,該 :軸上另具有一第二部分,其可插置入該欲裝置該腳輪之 &具件上之-座中’其特徵為該第二部分包括—具有一減 J、直U形成-肩部之端桿,—轴襯被轴向地固定於該端 桿上並配合該肩部而形成—環形槽,以供無轴向餘隙地容 納-彈性環,該環適於藉由擴張而壓抵住㈣處之該壁。 【實施方式】 參照圖1至8,參考數字丨概括地代表—自行定向型雙腳輪 之總體,其包括一用於支撐兩輪子3之支撐結構2,而該兩 輪子被裝設成使其可轉動於一共同軸8上,該軸8具有一水 平軸線A且係經由該結構之一座而被驅動。 該結構2係由塑膠或金屬材料製成且包含一具有一直立 軸線之凹處4,且該凹處位於該等輪子3之間並可容納—挺 軸5,而經由該樞軸可將該腳輪以梅接方式安裝至一件家具 上’該家具例如一椅子’其上設有一包含諸徑向臂之把架, 96971.doc •6· 1342272 而在該等臂之諸端部處設有供安裝該等腳輪之諸座。 如圖5至8中所更清楚顯示者,該用於樞轉該腳輪之樞軸$ 在結構上係呈圓柱狀且包括一下部6及一上部7,而該兩部 藉由一環形凸緣8而被彼此分隔開。一環形槽9置於該下部6 中,而一圓錐穴10則置於該下部6之端部中。 該下部6被插入該凹處4中,在此處為了保持該樞軸5可呈 軸向定位而設置有一内軸環,其藉著強力推進而與該槽9 相嚙合。一鋼球(圖中未示)被合宜地配置於該凹處4之底 部,且其藉由嚙合於該凹面丨〇上而作為用於支撐該承受於 該腳輪上之負荷的一支撐點。 該樞軸5之上部7在接近該環形凸緣8處包括一朝向該凸 緣作剩》八狀展開之圓錐狀連接區域Η,以及一具有一減小 直徑以形成一端桿12之區域。該端桿12以一肩部η而與該 上部7之其餘部分相隔開。此外,一死端孔丨4轴向地成形於 該端桿12之自由端且被一環形唇部15所包圍。 一由塑膠材料製成之軸襯16被裝設於該端桿12上,且該 轴襯之長度使其一旦被配置於該端桿12上時可配合該肩部 13而共同形成一環形槽17 ^ 一敞開狀且具彈性(亦即可彈性 地擴張)之金屬環18被配置於該槽17中並具有一圓形之截 面’且該金屬環在已擴張之狀況時具有一略大於該上部7 直徑之外徑及一至少等於該端桿丨2直徑之内徑。 該環18經由該轴襯16而被鎖制於該槽π中,該轴襯並依 序地藉由一環形脊部而被保持在該端桿丨2上,而該環形脊 部係經外摺該唇部15而形成者。以輕微之干涉狀態將該轴 96971.doc 1342272
襯16裝設於該端桿12上,且該軸襯16之位置被設定成可使 該環18在該槽17中不具有軸向餘隙,但該環可於該樞轴被 插入其位在該件家具(椅子)中的座内之同時徑向地閉合於 該框轴上。 該唇部15所達成之固持作用可以有利地協助鎖制該轴襯 16於該端桿12上’如此可確保甚至經長期使用及在不良之 操作條件中亦可達減小該腳輪噪音之效果。 應注意的是該環1 8之噪音減小作用是在徑向及轴向兩方 向上發生的。一旦該樞軸5已經插入其位在該件家具(椅子) 中的座内,該環18藉由其較大之徑向直徑而壓抵住該座之 壁,以便可抗衡從該樞軸經由該腳輪而傳遞至該托架之橫 向震動。在此同時,本發明創新觀念中之一主要的特點在 於,該轴襯16藉由軸向地作用在該環18上之鎖制效 藉由該唇部15而被鎖抵住該肩部13),以阻止其有任何2軸 向運動,因而防止了震動之發生。 *在其實際之具體實施例中’本發明容許有許多之修改及 變更’但此所有的修改及變更均落在相同之創新觀念的範 圍:。…例如該彈性環18可具有一方形、矩形或橢圓 戴面。有利地,該彈性環18具有彼此呈軸向偏位之相對 :部(其形成該環之間隙),以致使一旦該環被插入該槽口 ^該等端部之—壓抵住該軸襯16,而另_端 住該肩部1 3。 圖9-11顯示該腳輪之 置—死端孔14,且用於 一實施例,其中該端桿12上並未設 固持該軸襯16之該唇部15係藉由在 9697l.doc 1342272 該端桿1 2之外緣形成頭部而獲得,以致可形成一從該端桿 12向外伸出之轴環,並藉由轴向地作用於該軸襯16上而可 保持該環1 8於受壓縮狀態下。 【圖式簡單說明】 本發明之進一步特徵及優點從以上有關一腳輪之一較佳 但非唯一實施例之詳細說明而變得顯而易知,該實施例並 藉由附圖中之非限定用範例予以說明,而在該等圖式中: 圖1係具備根據本發明之創新所實施之一自行定向雙腳 輪之一立體圖; 圖2係圖1所示之該腳輪之一側視圖; 圖3係圖1所示之該腳輪之一前視圖; 圖4係圖1所示之該腳輪之一平面視圖; 圖5係用於樞轉該腳輪之柩軸之一視圖; 圖6係圖5所示之該樞軸之一分解圖; 圖7係圖5所示之該樞軸之一剖面視圖; 圖8係圖5所示之該樞軸之一軸向視圖; 圖9係根據另一實施例之—樞軸之一立體圖; 圖10係圖9所示之該枢軸之一分解圖;及 圖11係該樞軸之端部之—剖面視圖。 【主要元件符號說明】 1 自行定向型雙腳輪 2 支撐結構 3 輪子 4 凹處 96971.doc -9- 1342272 5 樞軸 6 下部 7 上部 8 凸緣 9 槽 10 穴 11 連接區域 12 端桿 13 肩部 14 死端孔 15 唇部 16 軸襯 17 槽 18 環 S 共同軸 A 水平軸線 96971.doc -10-
