Abstract
A handle driven wheelchair has left and right handles with ratchet. Alternatively pushing both handles can make their ratchets to drive big gears and in turn the wheelchair.
Description
Technical field
The present invention relates to the bicycle field.
Background technology
Known traditional push chairs is to move fixedly iron ring on the wheelchair wheel with hands when using, when making before the wheelchair, retreat, turn.
Use is travelled needs hands to stretch the iron ring of pulling on the wheel backward forward or rotate backward, and wheelchair is travelled, and the wheelchair of this structure not only travel speed is slow, operates also gruelling.Tire also rub arm, coat-sleeve, very inconvenient.
Summary of the invention
The purpose of this invention is to provide a kind of wheel chair powered by handle light, laborsaving, convenient, that the simple push handle will make wheelchair advance, retreat, turn of operating.
Technical scheme of the present invention is achieved in that left and right operating grip, driving handle is housed that the ratchet on the handle drives gear wheel automatically and rotates, and rotates forward for driving wheel chair wheel through third wheel on wheelchair.
Hold handle and hold brake lever simultaneously, pulling handle another ratchet this moment drives gear wheel rotates backward wheelchair through third wheel.The proficiency handle, another is held another handle and holds brake lever simultaneously, and both hands are made opposite push pull maneuver, and wheelchair is finished turning action.
Level is put down handle, and wheelchair can promote to travel, and the wheelchair speed that travels is finished by the gear ratio adjustment.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
1,2 handles among the figure, 3,4 ratchets, 5 gear wheels, 6 third wheels, 7 drives, 8 brake levers, 9 fens alligators.
The specific embodiment
Handle 1,2 promotes simultaneously or monolever promotes wheelchair to overtake, and ratchet 4 and gear wheel 5 meshing and rotations when handle 1,2 promotes drive the drive 7 that is connected on the wheelchair wheel wheel Hub through third wheel 6 and rotate, and wheelchair to overtake.
Pulling handle 1,2 lifts with advancing to hold the ratchet 4 that brake lever is connected on the handle for 8 this moments, and ratchet 3 and gear wheel 5 are meshing to drive drives 7 through third wheel 6, and wheelchair is travelled backward.Hold handle 1, another holds handle 2 and holds brake lever 8 both hands simultaneously and do push pull maneuver, the ratchet 3,4 that be connected on the handlebar this moment is meshing with wheelchair both sides gear wheel 5 respectively, makes wheelchair both sides drive 7 different directions rotation forwards, backwards through third wheel 6, reaches the purpose of turning about wheelchair.
Separate pins 9 is separated ratchet 3,4 with gear wheel 5 when 1,2 handles are placed on horizontal level, promotes to travel in order to wheelchair.
