换向机构 64使前后摇摆双向都有作用，一般位于增速装置 25之 后， 也可位于增速装置 25之前， 使增速装置 25不必反转。用摇摆输 出以一正方向及一反方向，同时带动两个同向的单向装置 7、 7a即可， 现有改变转向有许多种方式， 最普通可在拉 -站或推-坐任一多加一转 轮后， 才传到各单向装置即可， 并用回力弹簧使各自回位。本发明更 可采用特别方式如图 la、 图 5a所示。
图 la， 由摇摆臂带动而来回运动的链条 6， 以外圈方式带动分配 轴 72的一边链轮 72a， 之后以内圈方式带动后轮一边的单向装置 7; 因而分配轴 72反转， 另一边链轮 72b再带动另一边链轮 6a， 以内圈 方式带动后轮另一边的单向装置 7a; 惰轮 72c仅保持分配轴 80带动 后轮的咬合性。
图 5a采用两咬合的齿轮 51、 53， 其各自连动同向的单向链轮 7、 7a, 一链条围绕单向链轮 7、 7a后带动被动链轮 56， 惰轮 55a、 55b 为引导及确保链条咬合作用； 齿轮 51或齿轮 53以任意方向旋转时， 其中一单向链轮 7或单向链轮 7a会单向的带动被动链轮 56; 这方式 简洁、紧凑且非常合适配合应用于一般自行车脱轨器如图 5所示。所 述的两单向装置 7、 7a可为自行车的飞轮或单向轴承， 其两者都为同 向安排， 且可让车辆作滑行功能。
所述的移动座 70其支架可为任意形状， 如倒 U状如图 1所示， 以避免任何机械机构冲突， 所述的座力臂 70a在车架两边各一， 形成 一对以利平衡如图 4所示，而座力臂 70a的另一端固接于其转轴心轴 70b, 示情况所需可为一通过车架的一心轴且连接两边的座力臂如图 中所示， 或两边各自有转轴心轴于车架上。 所述的移动座 70其有两 种形态， 如图 1所示， 座位与力臂一体连动而以力臂心轴旋转， 如此 有助于推 -坐时施力的角度； 另一形态如图 2所示， 其移动座永保垂 直状态， 其在座力臂轴上方具有一对转轴及移动座 70下方具有一对 转轴， 并有一对平行杆于座力臂之上， 而形成一随时保持平行四边形 的机构， 可随角度变动而能保持移动座 70的垂直移动。为易于收藏， 移动座可插入一套管架固定， 且可以拆卸如图 12所示， 另有一缓冲 弹簧 75a保持行程到底时的舒适。
同样， 所述的踩板 71连接踩力臂 71a的一端， 如在车架两侧形 成一对以便平衡施力，踩力臂 71a的另一端固接转轴心轴 71b也同前 述： 可通过车架， 连通两端转轴心轴 71b或两边各自有转轴心轴于车 架上 (如图示)。同样踩板 71连踩接力臂 71a可如前述一体件随心轴旋 转或用平行四边形方式随时保持垂直如图 12所示。踩板 71可为圆棒、 平台、 自行车踩板或任何形状物件能供脚踏下产生扭距。
另外， 为能使相互回位， 两枢轴之间有一连动机构 73 以齿轮、 正时轮、 链轮、 链条， 皮带等等相互连接， 使踩板心轴 71b及移动座 心轴 70b， 有如跷跷板作用， 一个动作同时会令另一个复位。 如图 2 所示， 由移动座心轴 70b上的齿轮 73c经一链条 73d带动齿轮组 73e 后连动踩板心轴 71b上齿轮组 73e; 这也可调整踩板及移动座间的施 力时间比例，使达到最佳工作平衡，因一般坐施力时间长于站施力时， 会比较舒适些。
所述的踩板转轴心轴 71b及移动座转轴心轴 70b各连接其力臂， 并受车架上轴承支撑，并示情况可由其中一个或两者共同连接所述的 摇摆驱动介质 68a，输出动力到所述增速装置 25 ;因分别转轴的缘故， 各施力可分别设置成顺时钟或反时钟方向；更进一步也可单独存在来 简化结构， 以单独一单向装置 7及单踩板 71作单一带动方式为例， 其回位可由一回力弹簧来实现 (未示)或以脚钩于位踩板 71 上方的钩 棒 71e， 用提脚动作回位； 同样， 单独移动坐方式可用弹簧拉高回位。
所述的踩板转轴心轴 71b及移动座转轴心轴 70b可以合而为一， 而形成如跷跷板单横梁 73a及其单转轴 73b， 有如先例所述， 或两力 臂形成一角度 (最好于 120度至 180度之间， 但并不限于此） 以应用 于较低的底盘车架如图 6所示。所述的跷跷板横梁 73a前端支撑踩板 71而后端连接移动座 70而其单转轴 73b受车架 5上轴承所支撑。
图 5所示， 使用大圆上的一小段齿条 88连于移动座 70后方， 来 带动一小齿轮 88a， 再转变成大链轮 88b， 以链条 88c带动增速装置 25 , 此如同于以心轴 73b旋转， 并两端以拉物带动方式同效果； 而拉 物带动的应用， 可于踩板及移动座下连接链条， 并用惰轮引导环绕过 增速装置的输入轮后由车架上回力弹簧拉着以使回位 (未示)。
图 4、 6、 7例举了许多可行例， 其中包含增速装置 25、 变速及 换向机构 64的可行例。 参考图 7， 而图 6为其侧透示参考图； 当脚 踏下踩板向下时使移动座 70上升回位以便连续下个循环， 因单枢轴 73b实接于两端齿轮 25a于摇摆驱动介质 68a， 并从左右两边带动两 组在心轴上可自由转动的齿轮组， 做部份增速后， 齿轮 77与心轴 75 相连， 如此可以双套来分摊起始的重负载， 再做部份增速后， 最后带 动一位于心轴 76上且具有不同间隔距离的三个齿轮的长齿轮 79 (一 个四倍齿宽，另一个两倍齿宽)，长齿轮 79与另一类似的长齿轮 80(最 宽一个为两倍齿宽)可在不同位置相对不同齿比； 长齿轮 80位於心軸
78上且受一有播叉的排挡杆 81控制， 不同距离位置可使一齿轮离开 后再入另一齿轮以防同时入两齿比， 排挡杆 81停在一个定位格选择 器 82; 轴套 85可保持排挡杆 81排挡时另一端不至于突出太多于外。 长齿轮 80用长键 84带动一链轮 74， 最后带动换向机构 64的两单向 装置 7、 7a带动后轮前进。
图 8 、 图 9显示一固定座 70d的脚踏车以单独踩板且双向作用 力方式的实施例， 其踩板 71下方有一配重 71d以保持一钩棒 71e永 远位于脚背之上， 当拉站时， 踩力臂连增速装置输入轮 25a带动换向 装置 64使链条 55带动脱轨器的三链轮组 56b， 然后以脚背钩住钩棒 71e, 以腿及腹肌抬高踩板 71回位， 因而可以循环继续。
图 10、 11为本发明能以单横梁单轴方式， 结合自行车脚踏功能 的实施例； 使用者可选择一般脚踏的方式或以体重摇摆方式来操作。 参考图 1 1， 踩板 71与移动座 70转轴心轴 73b连接增速装置 25输入 齿轮 25a， 其带动自由旋转的齿轮组 25b， 25b与自由旋转的齿轮组 25c咬合， 而 25c包含有具有棘轮 7的齿轮 51， 51连动具有棘轮 7a 的齿轮 53， 一传动链条 55以惰轮 55a调紧且连动两棘轮 7、 7a及一 链轮轴 56a上一被动链轮 56，链轮轴 56a也包含有脱轨器的三链轮组 56b, 其连按经脱轨器链条 44经变速带动后轮 8; 链轮轴 56a外径上 含有由车架 5支撑的两轴承 56c， 而内径含有单向轴承 45， 让自行车 踏板 43及踏板轴 43a单向的带动链轮轴 56a， 如此让摇摆机构 68能 在踏板轴 43a不动或反转时， 超速的带动链轮轴 56a。 如图 11所示， 移动座 70及踩板 71为'推-坐 '到达行程限制块 41停止点的位置， 且 此位置可为使用自行车踏板功能的位置， 而移动座 70'及踩板 71 '为' 拉-站 '到达行程限制块 42停止点的预定位置。
图 12部份展示一可折式前轮总成，固定销 86锁住前轮总成于车 架上两个特定位置并用螺帽 87固锁固定销 86定位。
本发明亦可加入悬吊、刹车、灯光等等系统使合法行驶于马路上， 或应用一般滑板车折迭技术来收藏。
以上公开的仅为本发明的几个具体实施例， 但本发明并非局限于 此， 任何本领域的技术人员能思之的变化， 都应落在本发明的保护范 围内。
