Description

自行車快拆結構
本發明係一種自行車快拆結構，乃使自行車快拆結構之鎖迫桿及連動桿，於需旋轉鎖緊、放鬆可連結而連動，於鎖緊後鎖迫柄即脫離鎖迫桿，而得不會因震動造成鎖迫桿鬆動，達到安全功效。
查，習知之自行車快拆鎖迫結構，大體皆如圖一、二所示，係一鎖迫桿10穿組於輪軸，其一端設螺帽11而鎖合於車架16，另一端設連動桿12，鎖迫柄13、定位座15，連動桿12與鎖迫柄13之組合結構，係設成連動桿12具有連結頭14而呈偏心樞組合於鎖迫柄13中，當扳轉鎖迫柄13向下、向上動作時，可使連動桿12、鎖迫桿10動作，達到鎖迫緊、放鬆之目的；上述結構，其實存在有下列缺點：
(1)鎖迫柄13與連動桿12之組合結構，設成連結頭14直接穿組於鎖迫柄13，因此，鎖迫柄13只能上、下扳轉角度，無法調整左右角度，故需設螺帽11輔助鎖緊，而此螺帽11即是會有因震動而放鬆、鬆脫之問題。
(2)因鎖迫柄13不能調整左、右角度，而鎖迫柄需呈向下狀態抵貼定位於車架16，故，其必需配合螺帽11之鎖緊方可調整鎖迫柄13之角度，極麻煩、費時。
(3)尤其，連動桿12係直接螺合於鎖迫桿10之螺孔101，當鎖迫桿10鎖緊後，連動桿12仍連結於鎖迫桿10，故會有因「鎖迫柄13被誤碰觸轉動」、「行驅中之震動」造成連動桿12誤動作而使鎖迫桿10鬆動之虞，較不安全。
(4)定位座15無補強結構，耐力強度較差。
本發明即是改善上述習知之問題，主要技術、目的為：
其一，鎖迫桿一端設外螺牙鎖合於車架，另一端設螺孔，螺孔中設多邊形 槽，連動桿設有與多邊形槽相對應之多邊形頭，當欲旋轉鎖迫桿鎖緊、放鬆時，連動桿之多邊形頭可嵌入鎖迫桿之多邊形槽，形成可驅動旋轉。當鎖迫桿鎖緊後，連動桿之多邊形頭可脫離多邊形槽，而得不可驅動旋轉鎖迫桿，達到定位穩固，不會有因震動造成鎖迫桿誤鬆動之問題，安全功效佳，其鎖迫柄並可因此隨意設定位任何角度。
其二，鎖迫柄所抵觸之定位座設有內螺牙而組設一補強螺套，定位座中並設有中空之螺栓螺合於鎖迫桿，藉由補強螺套，螺栓，而得形成增大耐力強度之功效，因此可得更增大鎖迫定位之強度。

第6圖本發明連動桿之多邊形頭脫離不可驅動狀態圖
請參閱第3、4、5、6圖，係包含：鎖迫桿20、連動桿22、定位座28、連結頭25、鎖迫柄24；連動桿22與連結頭25連結、及組合於鎖迫柄24中，連動桿22並組入鎖迫桿20中，鎖迫桿20一端具有外螺牙202而鎖合於車架17；其中，該鎖迫桿20另一端設有螺孔201，螺孔201中設有多邊形槽21；該連動桿22設有與多邊形槽21相對應形狀之多邊形頭23，鎖迫柄24可使連動桿22前進而得多邊形頭23嵌入鎖迫桿20之多邊形槽21，形成可驅動旋轉鎖迫桿20，亦可連動桿22後退使多邊形頭23脫離多邊形槽21，形成不可旋轉鎖迫桿20；該鎖迫桿20之螺孔201組設一具有通孔270之螺栓27，螺栓27係穿過定位座28，連動桿22係穿過螺栓27之通孔270；該定位座28設有內螺牙280，並設有補強螺套26，補強螺套26具有外螺牙260而螺合於定位座28之內螺牙280。
依據上述之結構，可形成下列之功效、優點：
(1)如第4、5圖所示，當欲旋轉鎖迫桿20鎖緊或放鬆時，連動桿22呈前進而使其多邊形頭23嵌入鎖迫桿20之多邊形槽21，旋轉鎖迫柄24(第5圖所示)、連動桿22即可連動鎖迫桿20旋轉。
(2)當完成鎖緊鎖迫桿20後，如第6圖所示，可使連動桿22後退，使其多邊形頭23脫離鎖迫桿20之多邊形槽21，因此，縱然外力或震動力造成連動桿22旋轉，亦不會有連動鎖迫桿20，而得鎖迫桿20定位穩固、不會有誤旋轉造成鬆動之問題，安全功效佳。
(3)因連動桿22可呈空轉，故可讓其鎖迫柄24設定定位於任何角度之位置。
(4)如第3、4、6圖所示，鎖迫桿20之螺孔201處設有螺栓27、定位座28設有補強螺套26，形成雙重補強效果，而得增大耐力強度，因此可承受強大之鎖迫力，達到更強之鎖緊效果、及不易變形損壞。
另，本創作之多邊形頭23亦可設呈橢圓形頭(即縱向軸距、橫向軸距不等距離之形狀)，鎖迫桿20並設有對應橢圓形頭之凹槽部，形成可驅動旋轉鎖迫桿20，亦屬本創作等效結構創意範疇。
本創作之多邊形頭23亦可設呈其他形狀，可匹配凹槽部，帶動鎖迫桿20迫鎖車架17。
綜上所述，本發明之結構、技術，確實具有極佳之實用功效，誠符合專利法之規定，懇請賜准專利。
