Description

承置板與腳輪座連動之手推車
本發明係在提供一種承置板與腳輪座連動之手推車，尤指一種可藉由撥動承置板同時可連動腳輪座展開腳輪或收合腳輪之目的。
按，目前一般所使用之手推車係採用固定式，因此相當佔用空間，而且不易收藏攜帶。
緣此，本發明人有鑑於上述習用之手推車所存在之缺失，乃加以研發改良，終於首創出本發明。
本發明之主要目的，係在提供一種方便操作手推車腳輪收合、展開之構造，進而達到方便收合、展開腳輪之手推車。
本發明之主要特徵：手推車架，該手推車架下方兩側設有樞接部，其中樞接部上設有定位座、定位孔及彈性元件，該定位孔係設於定位座下方；腳輪座，係設於手推車架之樞接部，該腳輪座中央設有套合孔與定位插孔，可供與手推車架之樞接部套合一體，而腳輪座一側組設有腳輪，另一側組設有撥動面與貼合面；樞接座，係設於腳輪座之套合孔下方與手推車架之樞接部結合，該樞接座上設有結合孔與定位穿孔，可供手推車架之樞接部穿設，並於樞接部下方之定位孔樞接定位，又樞接座一側設有樞接體與樞接孔可與承置板之樞接穿孔樞接定位；承置板，係樞接於樞接座之樞接體上，該承置板樞接於手推車架之定位座其兩側之撥動體並與樞接座上方腳輪座之貼合面貼合，而彈性元件推壓施力於各腳輪座提供折疊方向轉動扭轉力，使該承置板上之撥動體與腳輪座之撥動面相互嚙合，使腳輪座與承置板連動，因承置板下壓的撥動扭轉力作用，讓腳輪座的貼合面各自貼合抵持而上，使腳輪座保持展開位置，又當承置板向上撥動時， 腳輪座之貼合面即從承置板之撥動體脫離，進而使腳輪座扭轉從展開位置移動至收合位置。

請參閱第1圖、第2圖、第3圖、第4圖及第5圖所示，本發明實施例主要設手推車架2下方樞接部20設有定位座200、定位孔201及彈性元件202，其中彈性元件202可為壓縮彈簧、扭力彈簧或液壓裝置構成，該彈性元件202上設有定位構件2020與撥動構件2021，定位構件2020係插設於定位座200之定位孔2000；腳輪座3，係組設於手推車架2之樞接部20上，該腳輪座3中央設有套合孔30，而於套合孔30一側設有定位插孔300可供彈性元件202之撥動構件2021插設定位，而腳輪座3兩側則分別設有腳輪31與撥動面32，其中撥動面32上設有貼合面33；樞接座4，係設於腳輪座3之套合孔30下方並套設於手推車架2之樞接部20上，該樞接座4係呈狀，該樞接座4上設有結合孔40、定位穿孔41、樞接體42與樞接孔43；承置板5，係樞接於樞接座4上，該承置板5延伸有撥動體50，該撥動體50上有撥動面500、抵持面501及穿孔502，又承置板5於撥動體50內側設有樞接槽51，並於樞接槽51上設有樞接穿孔510；螺接元件N。
組裝時，先將彈性元件202之定位構件2020定位固定於樞接部20之定位座200之定位孔2000上，再把腳輪座3之套合孔30套入樞接部20上，同時使彈性元件202之撥動構件2021***定位插孔300，隨後把樞接座4之結合孔40套入樞接部20上並貼 合於腳輪座3之底部，再取螺接元件N由樞接座4之定位穿孔41穿入並穿過樞接部20之定位孔201螺設結合，再將承置板5之樞接槽51置於樞接體42上，以螺接元件N由穿孔502、樞接穿孔510及貫穿樞接孔43與樞接穿孔510後螺設固定，此時，腳輪座3之撥動面32即交錯於承置板5之撥動體50上，且撥動面32與500係成接觸連動狀態，如此，即可輕易完成組裝。
使用時，先將手推車架2下方之承置板5向下撥動，此時承置板5之撥動體50因上升之位移而將腳輪座3之撥動面32往承置板5之方向旋轉，故承置板5之撥動體50與腳輪座3之撥動面32作動同時連動腳輪31展開，當承置板5撥至定位時，腳輪座3之貼合面33即緊密貼合於撥動體50內側之抵持面501，因彈性元件202之定位構件2020與撥動構件2021扭力作用，讓腳輪座3完全定位不動，腳輪座3上之腳輪31即被推出與手推車架2呈展開定位狀態，如此，即輕易完成手推車架2之工作狀態。
當欲收合手推車架2時，僅需將承置板5向上撥動，此時，承置板5之撥動體50抵持面501即脫離腳輪座3之貼合面33，腳輪座3即受彈性元件202之撥動構件2021之扭力作用，而向手推車架2內收合呈貼合狀，如此，即可方便收合手推車架2置放收藏不佔空間者。
惟以上述者，僅為本發明之一較佳實施例而已，當不能以此限定本發明之實施範圍，即凡依本發明申請專利範圍及發明說明內容所作之均等變化或修飾，皆應仍屬本發明專利涵蓋之範圍內。
