Abstract

The pedal-type monocycle has five structural forms: the first one as one monocycle, the second one with two auxiliary wheels in the back of the main wheel, the third one with single wheel and handlebar, the fourth one with both auxiliary wheels and handlebar, and the fifth one with saddle. The five forms have different functions, and may be reformed easily. The pedal-type monocycle has one unique driving mechanism comprising pedals and pull rods in the lower ends of the fork, chain connected to the pull rods, flywheel connected to the chain and fixed onto the hub. The pedal-type monocycle is driven forward via alternate pedaling the pedals, which are repositioned automatically with springs. The pedal-type monocycle is small, smart, comfortable in driving and flexible, and is used as novel carrier for recreation and replacing walking.

Description

Pedal-type monocycle

Affiliated technical field:

The present invention is a kind of pedal-actuated unicycle.

Background technology:

It is a kind of dream that the men of old pursues " Hot Wheels ", and modern's pursuit is travelled and moved with car and become a kind of fashion, nowadays scooter, slide plate, the just fashionable world of wheel footwear.Unicycle is owing to have the special efficacy of tempering people's balance, the coordination ability, thereby lasting, and is in extremely young student's favor of Japan, also in the ascendant in China.Because wheelbarrow adopts the type of drive of the standard bicycle of foot-operated rotation, and has the body gravity height, drive uncomfortablely, control defectives such as difficulty is big, thus be difficult to become popular travelling and tool movement, more can not be as a kind of instrument of riding instead of walk with wheel.

Summary of the invention:

For solving some defective that existing wheelbarrow, Kickboard Scooter, slide plate, wheel footwear etc. exist, functions of use and applicable area that expansion is ridden instead of walk with wheel, the present invention designs a kind of simple and practical body construction and actuating device, with reach drive comfortable, turn to flexible, widely used purpose.

The technical scheme that the present invention is taked for the technical solution problem is: this car has five kinds of versions, with the demand that adapts to people's personalization and the use of different places.In first kind of structure, be made of wheel, car fork, fixing feet pedal and actuating device, wheel is installed in car and sticks, and two fixed pedestals are welded on the below at car fork two ends.This kind structure requires high to roadcraft.Second kind of structure adds a crossbeam, wheel shaft and two jockey pulleys in the back of first kind of structure, the crossbeam upper end is fixed on the steering shaft sleeve of the car side of sticking, and the lower end is connected with wheel shaft.This kind structure can strengthen stability, the safety of car operation, and the people can stand onboard when stopping.The third structure installs handlebar additional on first kind of structure, handlebar is fixed on the car side of the sticking steering shaft sleeve, and is scalable to regulate height, and brake gear is housed on the handlebar.This kind structure can improve reliability that turns to and the stability of controlling.The 4th kind of structure is first three combination together of planting structure, the connector bushing of handlebar and crossbeam arranged, so easy accessibility after car fork steering shaft sleeve is gone forward.It is easier that this kind structure is controlled car, move more stable, turn to more reliable.The 5th kind of structure adds vehicle seat on the 4th kind of structure, can stand like this and drive, and the driving that also can be seated can be worked as seat and be had a rest when stopping.

Realize riding instead of walk with wheel, wheel is too little, drives as Kickboard Scooter, slide plate, wheel footwear etc. with pedaling, has the problem that drives effort, and wheel is excessive, as various bicycles, the problem that center of gravity is too high, car body is huge can occur, and is so promptly dangerous, takes again and deposits inconvenience.Solve this contradiction, key is the type of drive of bicycle use pedal rotation of will breaking traditions.The present invention takes a kind of simple and reliable type of drive, only several centimetres of stretchers apart from ground, the people stands a kind of as though walking upon flat ground sense of security onboard, drive with pedal type, the pin front portion is motionless, and the trampling pedal has been lifted up at the pin rear portion, just as remaining where one is, so not only drive laborsaving, steady but also car body is reduced greatly, center of gravity reduces greatly.

The actuating device of this car is, respectively there is a fixed pedestal below at car fork two ends, two fixed pedestals join with Active foot plate respectively by bearing, respectively there is a pull bar two Active foot plate back, and two pull bars join with chain respectively, and the other end of two chains is separately fixed on the teeth of flywheel, two flywheels are fixed on the wheel hub of wheel both sides, two retracing springs of suit on the wheel shaft, an end of spring are fixed on the Spring Card on the wheel shaft, and the other end interts in a teeth hole of flywheel.

The driving process of this car is: when people's pin rear portion trampling Active foot plate, pedal affects pull bar, chain, motion, chain affects flywheel to make forward rotation behind pulley, flywheel is when the drive wheels revolution moves ahead, tightened retracing spring, when time-out is lifted up at the pin rear portion, the idle running of retracing spring twisting flywheel negative sense, flywheel is on the chain roll wraparound flywheel, and chain is lifted to reference position to Active foot plate simultaneously.Adopt two pedal, round trip flight wheel drive unit, two pedals can step simultaneously, also can take turns to step, and do not disturb mutually, when taking turns to treadle, just the crank motion of flywheel are converted into the continuous revolution of wheel.

The invention has the beneficial effects as follows: this car has characteristics such as car body is minimum, driving is comfortable, maneuverability, so not only take and deposit conveniently, and be used in different kinds of roads and place, as city square, vacant lot, sub-district, shopping mall, sightseeing garden etc., even can travel at home.This car can be travelled as a kind of later-model leisure, the body building utensil, also can become a kind of broad-spectrum scooter.This car is promoted the use of owing to simple in structure, cheap also being easy to.

Description of drawings:

The present invention will be further described below in conjunction with accompanying drawing.

Fig. 1 is the combination assumption diagram of this car.

Fig. 2 is the total structure figure of this car.

Fig. 3 is the actuating device scheme drawing of this car.

Among the figure: 1, main wheel 2, jockey pulley 3, handlebar 4, fixed pedestal 5, Active foot plate 6, chain 7, main axle 8, flywheel 9, crossbeam 10, spring 11, pull bar 12, cover for seat 13, car fork 14, steering bearing sleeve 15, pulley

The specific embodiment:

In figure two, in three, main wheel (1) is contained on the stand-off of car fork (13), the wheel shaft of jockey pulley (2) and crossbeam (9) join, be welded with cover for seat (12) on the crossbeam (9), crossbeam (9) is contained on the steering bearing sleeve (14), handlebar (3) also is contained on the steering bearing sleeve (14), fixing feet pedal (4) is welded below the car fork (13), fixed pedestal (4) joins by bearing and Active foot plate (5), there is pull bar (11) Active foot plate (5) back, pull bar (11) joins with chain (6), the other end of chain (6) is fixed on the teeth of flywheel (8), pulley (15) is installed on the car fork (13), chain (6) affects the direction of flywheel with change and plays the effect that enlarges transmitting ratio through pulley (15) top, each suit retracing spring (10) of the both sides of wheel shaft (7), an end of spring (10) intert on teeth of flywheel (8), and the other end is fixed on the Spring Card on the wheel shaft (7).When Active foot plate (5) during by trampling, driving pull bar (11) moves down, pull bar (11) affects chain (6) to move down, and chain (6) affects flywheel (8) to do the forward revolution, has tightened spring (10) when the driving car moves ahead, when pin lifts, under the torsion of spring (10), make the idle running of flywheel (8) negative sense, chain (6) is winding on the flywheel (8), drive pull bar (11) simultaneously, Active foot plate (5) lifts immediately.When two Active foot plates (5) when taking turns to step, wheel (1) is revolution continuously just.
