可调式靠背椅的保健自行车
本技术属于自行车,尤其涉及一种可调式靠背椅的保健自行车
技术介绍
现有自行车类的(电动车、运动车、儿童车、三轮车…所有的人力蹬踏车)都使用三角鞍座。该鞍座卡在骑行者的裆部,人体的全部重量都压迫在人的会阴穴及其前方的尿道要害部位,更能使痔疮患者或经期妇女因该部受压迫或摩擦而带来痛苦,日久压迫也会给骑行者造成严重的损害或病变,即自行车病。现有自行车都是上下蹬踏,蹬踏的力度全靠双腿用力,所以骑行非常疲劳。专利文献号2721500Y公开了一种鞍座靠背座两用自行车,包括有框形车架,车架有横梁,横梁的前端连有三通管,横梁的后端连有立梁,三通管和立梁的下端连有前斜梁,前斜梁的后端连有后车叉,后车叉的外端与立梁的上端连有后斜梁,三通管中插有前车叉,前车叉的上端有车把,前车叉的下端有前车轮,后车叉上有后车轮,前车轮是14或16英寸的自行车轮,车架中间下部的立梁下端和斜梁相交处有中轴,中轴的两端分别有脚蹬臂,中轴与后车轮轴之间有链轮、链条传动装置,立梁的上端管口连有骑式鞍座,骑式鞍座下方有立管,立管插在立梁的上端管口中,在三通管的前部有前驱动轴架,前驱动轴架上有前驱动轴,前驱动轴的两端分别有脚蹬臂,其特征在于:车把与三通管间有多点定位螺丝钉,在横梁上有前立柱,前立柱上连有互相平行的两条水平方向的滑道,滑道与后车轮轴间连有后立柱,滑道上连有靠背椅,靠背椅的下方有与滑道相配合的滑块,靠背椅的靠背板是由下靠背板和上靠背板两段铰接相连组成的,座板和靠背板是铰接相连组成,中轴上有与中轴同轴的介链轮,前驱动轴与中轴上的介链轮间有链轮、链条传动装置。
