Title:
REVERSIBLE HUMAN-POWERED VARIABLE SPEED DRIVE DEVICE AND ROWING-IMITATING HAND-ACTUATED VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/098554
Kind Code:
A1
Abstract:
A reversible human-powered variable speed drive device, comprising: a rack (1), force applying handles (2), a driving force shaft (3), one-way overrunning clutches (4), a reset device (6), a variable-speed gear set (8), a reversing gear set, a neutral gear trigger and a reversing trigger. One end of each force applying handle (2) is fixed to an input end of the corresponding one-way overrunning clutch (4), and output ends of the one-way overrunning clutches (4) are fixed to the driving force shaft (3). The force applying handles (2) rotate around the driving force shaft (3) back and forth along a circular arc to do work, and driving force arms corresponding to the force applying handles (2) directly drive the input ends of the one-way overrunning clutches (4) to rotate forwards and backwards, so as to intermittently drive the output ends of the one-way overrunning clutches (4) to rotate unidirectionally. The output ends of the one-way overrunning clutches (4) are fixedly connected to an input end gear (81) of the variable-speed gear set (8) by means of the driving force shaft (3). A position-limiting device (5) for ensuring an angle less than 60 degrees is arranged between each force applying handle (2) and the rack (1). Also provided is a rowing-imitating hand-actuated vehicle, which can be reversibly driven and enables upper limb exercises, such that a user may exercise and have fun.
