Description

The dual drive wheel Wheel-chair

This utility model relates to the wheel Wheel-chair, especially refers to a kind of wheel Wheel-chair that pulls with pedal.

Existingly take turns single type of drive that Wheel-chair all adopts hand or both hands rotating-wheel, these unicity of taking turns the Wheel-chair type of drive make a lot of people with disabilitys can not use it, and they have only and rely on other people and help just can walk out the open air.

The purpose of this utility model is farthest to satisfy the hope that people with disability and old people think easily to drive up to alone open air, work, life and leisure.

The purpose of this utility model is achieved in that the dual drive wheel Wheel-chair, and it mainly is made up of vehicle frame, reversing controller, driving and steering mechanism.Vehicle frame is left and right symmetric closed-in construction, and by before, during and after the frame bar, left and right frame bar, and the munnion bar constitutes.Below the front portion of left and right frame bar, be provided with axis, be provided with back axle below the rear portion.There is trailing wheel at the back axle two ends, vehicle frame is provided with seat, it is characterized in that: in, left and right symmetry sets up two guide rods separately between the after-frame, left and right frame bar front portion is provided with the axis hole of being furnished with bearing, and is provided with axis in view of the above, be installed with on the axis can be positive and negative the sprocket wheel that rotates of direction, be arranged with chain on the sprocket wheel, chain links to each other with drive sprocket on the back axle through the reversing controller, and left and right frame bar rear portion is arranged with the axis hole of being furnished with bearing, and be provided with back axle in view of the above, be driving shaft.Drive sprocket on the driving shaft is for driving the driven wheel that back axle and rear wheel thereof rotate.Fuse by the munnion bar between preceding frame bar and the center bar, before keep left portion and right half of frame bar be provided with two columns, column top is provided with the axis hole of being furnished with bearing, axis hole is with and turns to fulcrum, turn to a shaft rear end to be provided with prong, link to each other with activation lever by latch, activation lever top is provided with handle, the bottom is provided with pedal rod, and the activation lever bottom links to each other with push-pull bar by latch, and the push-pull bar rear end is provided with connecting hole, it is enclosed within on the joint pin of reversing on the controller, before frame bar two ends be provided with the rotation hole of being furnished with bearing, the rotary axle box that the turning-bar front end is provided with therein, a left side, the right turn bar front end outside respectively with a left side, right front wheel shaft is fixed together.The turning-bar rear end upwards is provided with gathering sill, and connecting rod connects together left and right two turning-bars.

Above-mentioned design when with pulling or during with the pedal drive rod, drives chain through push-pull bar and reversing controller and moves, and rotates thereby drive drive sprocket, thereby makes Herba Plantaginis capable; On the contrary, when the control rod on the reversing controller is in the front groove position of reversing controller, drag drive rod with hand push or with foot, go after then can making car, when making with hands or foot that activation lever is left and right waves, by the interlock of push-pull bar, gathering sill and turning-bar, thereby drive front axle and front vehicle wheel turn to.

Below: embodiment further specifies again with accompanying drawing.
