Description

一种椭圆轨迹双驱动跑步自行车
技术领域
本发明涉及一种椭圆轨迹自行车, 尤其涉及一种椭圆轨迹双驱动跑步自行车。 背景技术
由于椭圆机具有对膝盖的冲击力小的特点, 虽然问世的时间比跑步机要晚, 但是发展迅速, 尤 其受体重偏重, 腰脊柱或膝关节有问题的人士偏爱。然而, 椭圆机只能在室内使用, 缺少与大自然 接触的机会和趣味性。 目前, 有人发明了椭圆轨迹跑步自行车。 如公告号为 CN101557978A 的中国专利文献, 发明 名称为 "由椭圆传动系统推进的自行车", 公告号为 GB2494263A 的英国专利文献, 发明名称为 "Mobile Elliptical Exerciser" (移动式椭圆训练器), 公告号为 US D526250S的美国专利文献, 发 明名称为 "Elliptical Bike" (椭圆自行车), 都是采用曲柄链轮椭圆传动系统, 使骑行者在自行车上 进行椭圆轨迹跑步成为了可能。 但是, 上述发明有一个共同的不足之处, 就是不能像在椭圆机上那样, 双手握住摆杆与腿同步 摆动双臂。为了克服上述不足,各种手握摆杆与腿同步摆动双臂的椭圆轨迹跑步自行车的发明也不 断被揭示, 如公告号为 FR2961474的法国专利文献, 发明名称为 "Apparatus Propelled by Muscle Power" (由肌肉力量驱动的装置), 公告号为 CN101242878A的中国专利文献, 发明名称为 "移动 椭圆驱动设备", 公告号为 US7967313B 1的美国专利文献, 发明名称为 "Recreational Vehicle with Elliptical Drive" (具有椭圆传动的休闲车)。 上述专利虽然实现了双臂与双腿同步摆动, 但都是在 三轮自行车上实现的。 虽然, 三轮自行车在稳定性方面有很大的优势, 但是, 存在转弯性能差、 结构复杂和灵活性不 够等缺点。而且, 上述两类椭圆自行车都是采用最基本的固定式脚踏板, 即脚踏板是固定不动地装 在提供椭圆轨迹的支撑连杆上,在循环运动时,脚踏板本身的角度变化完全对应于支撑连杆前后两 端的角度变化, 在这种情况下, 骑行者在运动过程中的脚尖和脚跟相对角度或施力部位, 与实际跑 步、走路时的形态不相吻合。 理想状态下的运动轨迹应该是, 当脚踏板位于轨迹的底部时(对应于 实际跑步、 走路时的脚底着地阶段), 脚踏面应接近水平(与地面平行), 而在轨迹的其它段(对应 于抬腿、 踩下), 脚踏面的前段应低于后端, 并且在最高处时斜角度最大。 如果骑车者的运动轨迹 与这种理想状态的运动轨迹存在很大差异, 就有可能对骑车者脚后跟的关节或肌肉造成伤害。 发明内容
