Abstract

The invention discloses a walking vehicle for old people, which comprises a vehicle body, a directional bar mechanism and a foot power driven advancing mechanism. The walking vehicle for the old people is characterized in that the vehicle body consists of a stud under frame, a driving seat stamping element, a chair shaped seat frame, a seat cushion, a push bar and a bottom cover; the directional bar mechanism consists of a handlebar, a holding bar and a directional linkage device, wherein the directional linkage device adopts a mode that a holding bar connecting piece drives four-link rods so as to control the advancing direction of two front wheels; the foot power driven advancing mechanism consists of a positioning shaft, a foot bar, a pedal, a swing rod, a primary sprocket wheel, a crank, a secondary sprocket wheel and a driving wheel; and the rotation generated by the foot bar, the swing rod, the crank and the primary sprocket wheel is transferred to the secondary sprocket wheel through a transmission chain so as to transfer the rotation to the driving wheel and make the walking vehicle for the old people advance. The vehicle adopts a mode of up-down treading with small amplitude, has no flywheel or other unidirectional rotating structures, can achieve the effect of stopping the vehicle while the feet stops, has low speed, and is suitable for the old people walking inconveniently to ride.

Description

Walking vehicle for old people

Technical field:

The present invention relates to a kind of car of old man's use of legs and feet inconvenience, particularly a kind of both can the station trampled up and down the walking vehicle for old people that can be seated and trample up and down and can move ahead again.

Background technology:

Be fit in the market the elderly, the elderly who is particularly suitable for legs and feet inconvenience is few at the professional car of closely going for a drive, having a walk, even says do not have, and this just progressively marches toward astogeny society to China and even the world and has brought great inconvenience.

Summary of the invention:

In line with considering for the elderly colony, design a kind of speed unhappy, safety is good, can be separately at the walking vehicle for old people of closely going for a drive, having a walk, this is undoubtedly a Gospel concerning the elderly and the elderly's family members.The object of the present invention is achieved like this, walking vehicle for old people: comprise a vehicle body, a directional bar mechanism, a foot power driven advancing mechanism, it is characterized in that: vehicle body is by saying the font underframe, driving seat and rush part, chair shape mounting, seat cushion, handle and end cover and form; Directional bar mechanism is comprised of this three part of handgrip, barre and direction linkage, and the direction linkage is to adopt barre to drive in flakes the four-bar linkage mode, thereby controls the front line direction of two front-wheels; Foot power driven advancing mechanism is made of fix shaft, treadle, step, fork, one-level sprocket wheel, crank, secondary sprocket wheel, drive wheel, the rotation that is produced by treadle, fork, crank and one-level sprocket wheel passes to the secondary sprocket wheel by driving chain, thereby pass to drive wheel, walking vehicle for old people is moved ahead.

The invention has the beneficial effects as follows: adopted four-wheel, make the steady not prone to tip over of this car, adopt the mode of trampling up and down by a small margin, the old man of legs and feet inconvenience is easily ridden, adopted the structure without flywheel or other unidirectional rotation, so that stopping, pin also stops, more convenient old man controls, and runs into a little relatively more slow slope since bipod with, can naturally not slide yet, have a sense of security for the old man who drives.
