2, two-wheeled cycle has direction lever, brake, transmission device etc., the jockey only controls left and right balance, and its deficiency place is that volume is large, " folding bicycle " that originally designed for private car, volume after folding is still large, but the person's of riding in a bus difficulty is played the effect of " convenience "; In recent years, people are along " micro-miniaturisation " thinking, and wheel is more and more less, takes turns the little comfort level of riding that has influence on again, does not have so far desirable product.People also notice the light of " wheelbarrow ", but owing to do not have direction lever, brake, transmission device etc., especially the jockey will have the ability of suitable balancing technique, grasp direction and braking, and in recent years learn the people who rides " wheelbarrow " and increasing, but just as sports events.

3, mostly existing short range walking-replacing tool is to sit or the posture such as rides, but modern medicine finds that human walking upright is best motion, the people should sit less, and current many people After Hours spend the more time to practice " walking " at walking machine, and health is the topic that the modern is concerned about most; How multirow is walked and is accelerated the requirement that the speed of travel is the modern.Human yearning ride, from skiing, skating, roller skating is loved by the people, and being considered as is the fastest motion of modern development; People begin to be familiar with self importance healthy and environmental protection, and people wish to have vertical walking-replacing tool, but also do not have ideal selection so far, " the intelligent scooter " of the U.S. (stand, electronic), but expensive being difficult to popularize.

Three, summary of the invention

Technical matters

The purpose of odd number wheel bicycle of the present invention: a kind of essential function of bicycle that possesses is provided, only has an inflation big wheel, some steamboats, trolley frame and two function spare parts, it is a kind of Portable multifunction bicycle; The present invention is provided with " striding type " bicycle and " vertical walking " bicycle two large functions, and with two spare part form differences, different " crank+stretcher " just selected in both conversions on the basic structure of odd number wheel bicycle, " striding type " odd number wheel bicycle is with " fixed crank+stretcher ", and " vertical walking " odd number wheel bicycle is with " binodal crank+with the stretcher of two support wheels "; " striding type " bicycle and " vertical walking " bicycle are two distinct forms of riding instead of walk; The user is that " riding " and pedaled stretcher at " striding type " bicycle, and the user is the weight shift position and realizes walking by the binodal crank at " vertical walking " bicycle; Odd number wheel bicycle of the present invention is exactly will be on " odd number wheel construction ",

One will from the structure with two bull wheels of tradition " striding type " bicycle and large vehicle frame " weight reducing " to only having two steamboats of an inflation bull wheel band and trolley frame, reach portable;

Two will realize non-maneuverable " vertical walking " bicycle at " odd number wheel construction ", on this odd number wheel bicycle, and the vertical walking of user, get on and off and on, it is the same to get out of a predicament or an embarrassing situation, but also continuous skating capable, stand, do not change the footwear trouble, vehicle frame need not fold, speed is similar with riding type bicycle but than riding type bicycle safety, can conveniently be with public transport, subway, and productive costs is low, masses afford to use, and allow the modern saves the more time in fast pace life, many a kind of enjoyment and many a kind of selections; This " vertical walking " odd number wheel bicycle has merged the advantage of bicycle, Kickboard Scooter, wheelbarrow, inline skate, gathered " skidding " flexibly, the controlling and quick and safety system of " bicycle ", it can steadily be ridden instead of walk safely on highway, and the use of can crossing the threshold need not to screw up discipline.

To achieve these goals, odd number wheel bicycle of the present invention, structurally, designed a kind of odd number wheel construction:

The odd number wheel construction is comprised of the wheel of three different sizes, these three wheels vertically are arranged in a straight line, the centre is the driving wheel of an inflation, has increased the steering wheel of a minor diameter Universal wheel structure in the rear position of its travel direction, and it and driving wheel are at the same level face; Anterior position at the travel direction of driving wheel has increased a minor diameter front-wheel, and this front wheel location is higher than driving wheel and steering wheel horizontal surface, and namely three wheels are not or not same plane; Driving wheel, steering wheel and front-wheel are connected a wheel and are connected with vehicle frame, at driving wheel wheel shaft is housed, vehicle frame is connected with rotating shaft by bearing, direction lever, handle etc. are set on the vehicle frame, be fixed with crank, canine tooth disc on the wheel shaft, brake and flywheel are fixed on the driving wheel, and the large fluted disc on the wheel shaft forms transmission device through chain, middle fluted disc group sheet and flywheel;

The odd number wheel construction adds " fixed crank+stretcher " and cushion forms " striding type " odd number wheel bicycle; The odd number wheel construction adds " binodal crank+with the stretcher of two support wheels " formation " vertical walking " odd number wheel bicycle, and cushion is made collapsible, when the descending of road surface, can be seated and slide;

" striding type " odd number wheel bicycle and standard bicycle compare: become a bull wheel and two steamboats from two bull wheels of standard bicycle, become a wheel shaft from three axles, large vehicle frame by carrying user's weight and transmission device becomes the clamping board type vehicle frame that only has the driving wheel size, the setting of former nearly two meters long bicycles by the odd number wheel construction be reduced to only be slightly larger than driving wheel size length, transmission device is finished by " folding transmission ", the odd number wheel bicycle is pushed the two-wheeled cycle of dynamical equilibrium to " single wheel " of " unstable ", again by the odd number wheel construction, allow user's the center of gravity can be before the driving wheel line of centers, rear swing; From motion: traditional two-wheeled cycle only needs to grasp left and right balance; And wheelbarrow except needing to grasp left and right balance external, is gone back the forward and backward balance of GPRS because only have a wheel, and the user needs technology on one's own account to reach balance, forms the weighing apparatus that has much difficulty in healing; And the odd number wheel bicycle has been owing to respectively increased a steamboat in that driving wheel is forward and backward, and the user can in time adjust the center of gravity position and only need to grasp left and right balance, and the odd number wheel bicycle is not standard bicycle " micro-miniaturisation ", and it has new characteristic.

" vertical walking " odd number wheel bicycle compares with existing " vertical " motion and walking-replacing tool: the sports events in-line skate need be bundled on the left and right pin, is splayed and advances, and the user need practise the long period and will learn wrestling; Scooter and " evil spirit wheel " need another the feet step on the ground commonly used; The intelligence scooter be electronic, only stand, price is high; " vertical walking " odd number wheel bicycle need not bundle footwear, does not need the feet step on the ground, but only needs just straight ahead of weight shift position, and is non-motor-driven, cheap.

How does the odd number wheel bicycle work?

The work characteristics of odd number wheel bicycle is: the work that always lands of the driving wheel of odd number wheel construction, because carrying user's stretcher is at the driving wheel line of centers, user's center of gravity may be before or after the driving wheel line of centers, it is unstable that driving wheel is formed, the present invention increases by a front-wheel before driving wheel, increase by a steering wheel thereafter, this structure make user's center of gravity take driving wheel as fulcrum between front-wheel and steering wheel " swing ", front-wheel and steering wheel all can only be a wheel job in any situation, because stretcher hangs in the driving wheel rotating shaft, user's center of gravity may be before or after the driving wheel line of centers, when user's center of gravity during in driving wheel line of centers the place ahead, driving wheel and front wheel landing, when user's center of gravity during at driving wheel line of centers rear, driving wheel and steering wheel land; Odd number wheel construction actv. overcomes " wheelbarrow " forward and backward shakiness and causes user's rollover phenomenon, has had odd number wheel construction user can not fall, and structurally the odd number wheel construction makes cycle frame be reduced to minimum;

To " vertical walking " odd number wheel bicycle, two support wheel work under Vehicular left pedal when user's left foot lands, two support wheel work under right steps when user's right crus of diaphragm lands; Appearance is take driving wheel as fulcrum, forward and backward each wheel, and left and right respectively have six of two wheels to take turns around phenomenon; This bassinet structure always has seven and takes turns, and actual only have 2 to 4 wheels at work (two support wheels under driving wheel and steering wheel or the front-wheel, stretcher) in moment; The use of making a general survey of wheel is historical, also do not occur filling 6 wheels of three kinds of specifications around the driving wheel outer shroud, and work only has at most four wheels, illustrates that also the mankind are left and right, left lateral walks to realize the complexity of non-motor-driven, mechanization.

The particularity of odd number wheel construction:
