Abstract
The invention discloses a bicycle for the old use, which has unique design. The bicycle comprises the frame, the handle, the wheels, the chair, the back wheel shaft and the feet-treading device. The feet-treading device is composed of the footplate, the foot-handle, the ratchet wheel and various kinds of gears. The invention can random change the swing angle of the foot-handle to reduce the energy usage.
Description
The present invention relates to a kind of rickshaw, specifically a kind of foot-operated up and down three-wheel chair car.
At home and abroad market does not also have this car at present.The elderly's (comprise not can by bike people) is as long as be sitting on the chair, and is foot-operated up and down, just can use, and can with situation firmly arbitrarily change step on the handle pivot angle, can reduce and exert oneself.
The object of the invention for the elderly provides safety, reliable, integrates that the elderly rides instead of walk, body-building, the pedal type bicycle for old people that lies fallow.
Realize that key of the present invention is a foot pedal apparatus up and down, become to rotatablely move by riding movement conversion up and down, its technical scheme is such: under the bevel gear between the left and right umbrella tooth piece of stepping on the handle is meshing with each other transmission, one of application of force step is downward, another is swing upwards, drives gear and ratchet on the turning cylinder respectively by the left and right straight-tooth piece of stepping on handle.Under two ratchets act on respectively, make the turning cylinder rotation, drive hind axle by the sprocket wheel that is contained on the turning cylinder by chain, wheel is rolled forward.Since turning cylinder can only folk prescription to rotation, when car will fall back backward, governor pull lever thick stick promotes ejector pin, gear is broken away from and left and rightly steps on straight-tooth piece engagement on the handle, turning cylinder just energy freely rotate.Wheel can fall back backward.This car includes: handlebar 1, governor 2, chair 3, front fork 4, front-wheel 5, Front brake 6, vehicle frame 7, foot pedal apparatus 8, chain 9, hind axle 10, back brake 11 up and down.This car foot pedal apparatus 8 up and down is connected on the vehicle frame 7, foot pedal apparatus 8 is by between upper box 80 and the lower box 81 up and down, common adapter shaft is to the anchor shaft 82 that be arranged in parallel, turning cylinder 83, bearing carrier ring 84, the nail axle 85 that connects vertical direction is connected the bevel gear 86 on the nail axle 85, and handle 87 is stepped on a left side that is connected and fixed axle 82 two ends.The right side step on handle 88 and pedal 89,89 ', be connected both sides axle sleeves 90,91 and gear 92,92 in the middle of the turning cylinder 83 ' and ratchet 93,93 '.Turning cylinder 83 1 ends connect spring 94, and the turning cylinder 83 1 ends outside also connects sprocket wheel 95.Also have pin 96 connecting bushing 90,91 and turning cylinders 83.Bearing carrier ring 84 outsides connect pin 97, and bar thick stick 98 is promoted 99 formations.Bevel gear 86 meshes respectively that handle 87 is stepped on a left side, the umbrella tooth piece on the handle 88 is stepped on the right side, and a left side is stepped on handle 87, the right side and stepped on straight-tooth piece engaging gear 92,92 ' and ratchet 93,93 ' action respectively on the handle 88.Bar thick stick 98 promotes ejector pins 99, and ejector pin 99 1 ends insert in turning cylinder 83 holes and head on pin 96, makes axle sleeve 90,91 and gear 92,92 ' move.Spring 94 is being pressed axle sleeve 90,91 in addition, can make gear 92,92 ' reset.Also have a left side to step on umbrella tooth piece and the straight-tooth piece that handle 87, the right side step on the handle 88 and be all one respectively.Ratchet 93,93 ' on the outer ring have respectively gear 92,92 '.
Pedal type bicycle for old people of the present invention, car can be stepped on the handle pivot angle with changing arbitrarily with the car situation, to reduce firmly.And do not step on the strong points such as safety measure that car also can not glide automatically on the Che Zaipo.
Description of drawings:
The front view of figure one car of the present invention;
The birds-eye view of figure two cars of the present invention;
Figure three is critical component of the present invention embodiment front views of foot pedal apparatus up and down;
Figure four is critical component of the present invention embodiment A-A cutaway views of foot pedal apparatus up and down.
Below in conjunction with accompanying drawing pedal type bicycle for old people of the present invention is described further.
Shown in Fig. 1-Fig. 4, this car includes: handlebar 1, governor 2, chair 3, front fork 4, front-wheel 5, Front brake 6, vehicle frame 7, foot pedal apparatus 8, chain 9, hind axle 10, back brake 11 up and down.This car foot pedal apparatus 8 up and down is connected on the vehicle frame 7, foot pedal apparatus 8 is by between upper box 80 and the lower box 81 up and down, common adapter shaft is to the anchor shaft 82 that be arranged in parallel, turning cylinder 83, bearing carrier ring 84, the nail axle 85 of connection vertical direction is connected the bevel gear 86 on the nail axle 85, a left side that is connected and fixed axle 82 two ends step on handle 87, the right side step on handle 88 and pedal 89,89 ', be connected both sides axle sleeves 90,91 and gear 92,92 in the middle of the turning cylinder 83 ' and ratchet 93,93 '.Turning cylinder 83 1 ends connect spring 94, and the turning cylinder 83 1 ends outside also connects sprocket wheel 95.Also have pin 96 connecting bushing 90,91 and turning cylinders 83.Bearing carrier ring 84 outsides connect pin 97, and bar thick stick 98 is promoted 99 formations.Bevel gear 86 meshes respectively that handle 87 is stepped on a left side, the umbrella tooth piece on the handle 88 is stepped on the right side, and handle 87 is stepped on a left side, and respectively engaging gear 92,92 ' and ratchet 93, the 93 ' action of straight-tooth piece on the handle 88 is stepped on the right side.Bar thick stick 98 promotes ejector pins 99, and ejector pin 99 1 ends insert in turning cylinder 83 holes and head on pin 96, makes axle sleeve 90,91 and gear 92,92 ' move.Spring 94 is being pressed axle sleeve 90,91 in addition, can make gear 92,92 ' reset.Also have a left side to step on umbrella tooth piece and the straight-tooth piece that handle 87, the right side step on the handle 88 and be all one respectively.Ratchet 93,93 ' on the outer ring have respectively gear 92,92 '.
Should point out ratchet 93,93 ' be handle ratchet wheel, inner structure is identical with bicycle freewheel.Its critical component up and down parts in addition of foot pedal apparatus 8 and by grease lubrication, to reduce the transmission resistance, all is equipped with antifriction-bearing box in rotation place all in upper and lower casing, and resistance reduces friction.
The utilization and operation process of this car is such: to step on pedal 89 downward when people's pin, and the straight-tooth piece driven gear 92 on the handle 87 is stepped on a left side, and ratchet 93 no effects idle running.A left side steps on that umbrella tooth piece on the handle 87 drives bevel gear 86 and the right umbrella tooth piece of stepping on the handle 88 makes pedal 89 ' upwards swing in addition, the right side step on straight-tooth piece driven gear 92 on the handle 88 ' and ratchet 93 ', under ratchet 93 ' effect, turning cylinder 83 is rotated, make sprocket wheel 95 drive hind axle 10, wheel is rolled forward by chain 9.Same principle, when people's pin step on pedal 89 ' after, sprocket wheel 95 is rotated.So two top-cross for pin step on pedal 89,89 ', just can make car continuously forward the rolling.When car will fall back,, pressing by bar thick stick 98 and to promote 99 by the handle on the moving governor 2 of people's palm, head on pinning 96, axle sleeve 90,91 is moved on turning cylinder 83, make gear 92,92 ' respectively break away from the left and right straight-tooth piece of stepping on the handle, car just can fall back backward, freely rolls.After falling back, to original position, spring 94 is being pressed axle sleeve 90 governor 2 plates, and axle sleeve 91 moves, and makes gear 92,92 ' respectively mesh the left and right straight-tooth piece of stepping on the handle 97,88, and car just can have been stepped on capable.
