Description

Double driven bicycle

The utility model belongs to conveying arrangement, and it relates to the combined bicycle that a kind of trick all can be sent propulsive effort.The current bicycle that generally uses is simple foot-propelled power, does not allow dynamic both hands participate in driving power, both hands outage during driving, and blood follows not smooth, and it is cold endures cold by bike easily.Therefore the people is all arranged at the later-model trick power bicycle of research both at home and abroad.For example " scientific experiment " 1 phase in 1984, the many person bicycles of wind are split by the U.S., and last staff turns to, pin drives, but back dough figurine trick power; Chinese invention patent 85106803 " chair-typed bicycle driven by both hands and feet " is that handlebar is connected with hinge wheel through the crank connecting rod, and trick replaces work done; China's utility model patent 86207389 " bicycle with hand driving device " is that the hand-drive bar is housed on handlebar, by the power combination mechanism the synthetic back of trick propulsive effort is exported.These mechanisms are more complicated all.

The various bicycle sidecars of Chu Shouing all do not have actuating device in the market, and can only make sidecar and can not it use.If bicycle body can be dismantled from the middle part, later half car body is used as the new bicycle sidecar that has actuating device, then its functions of use and degree of utilization can be enlarged, and road speed and carrying capacity after the sidecar assembling can be improved.

The purpose of this utility model:

1) provide a kind of trick to drive simultaneously or separately-driven efficient single bicycle.

2) provide a kind of novel body-building, rehabilitation, amusement equipment.

3) provide a kind of energy Rapid Combination and the double driving bicycle that separates.

Overall structure (see figure 1) of the present utility model is used the basic structure and the standardized component of present standard bicycle, as front fork, trailing wheel, pedal, flashing board, back-wheel drive device, braking mechanism etc., it is characterized by: handlebar 4 installs the antifriction-bearing box that axis is a horizontal direction additional with the junction of pole 8, when handlebar control when the vertical axis of front fork is swung turns to; The crank 3 that is fixed on when horizontal axis is swung on the handlebar is swung thereupon, and pulling steel rope 2 drives duplex flywheel 1 reciprocally swinging and drives front-wheel.Handlebar 4 is equipped with locking pin 7 with the junction of pole 8, can handlebar is locked along the swing of horizontal axis, make handlebar identical with standard bicycle (only turn to and do not drive) when getting on or off the bus.When entering the cruising state, promote driving lever 5 through steel rope 6 with well, pull-up locking pin 7, the handlebar direction can drive front-wheel around the horizontal axis swing.Vehicle frame can be made compound type, dismantles along connecting pin 10 and locating bush 9 places, makes car body be divided into front and back two parts.Can install a handrail in the seat both sides additional when dismantling, rear brake cable and manipulation brake lever thereof are moved (the cable brake structure is adopted in brake) on the handrail that installs to the seat side from handlebar.Bend the frame 12(that can be articulated and connected on the flange that at the two ends of the perpendicular breeches pipe 11 of the vehicle frame of later half car body and see Fig. 2), the locating bush 9 places bar 13 that can be articulated and connected.The other end of pipe link and link span can be articulated on another bicycle (drawing with long and two-short dash line among the figure), is combined into the double driving bicycle that two people drive.

The utility model has the advantages that: both hands had not only been controlled and have been turned to but also can drive front-wheel, and trick can exert oneself also can replace respectively firmly simultaneously during driving, therefore than the effect height of standard bicycle, and indefatigability for a long time by bike.It can make the muscle at positions such as arm, pin, waist, abdomen, leg carry out fully movable and take exercise, and can make people's fitness, so it is not only a kind of vehicle, also is a kind of body-building, rehabilitation and amusement equipment.

After the later half car body of this car is loaded onto link span, pipe link and armrest, can be articulated to the double driving bicycle that is combined into double driving on another bicycle fast.Also can articulate child's seat on the link span, it is the energy-conservation vehicle that guest etc. was visited, picked to family of three.The combination of this car, separation and folding quick, convenient, the user's carrying that is beneficial to the inhabitation building is deposited.The parallelism of double driving bicycle two trailing wheels after the combination can be adjusted, so that reduce the sideslip kinetic power loss that tire forms because of the driving trace error.The quick hanging mechanisms of this car also can be applied to the not Regular Bicycle sidecar of tape drive mechanism.Suitably strengthen link span, and mix the hanging-connecting container, just can constitute and be fit to the outskirts of a town peasant and go down town and sell the modification of vehicle of dish etc.

The design's hand-drive mechanism can also be used for disabled person's three-wheel vehicle.Disabled person's three-wheel vehicle of Chu Shouing mostly is the singlehanded trailing wheel that drives in the market, and another hand shift turns to, if use the design's hand-drive mechanism instead, then can with the hands drive, and it will improve one times of effect than former singlehanded the driving, and transmission device is also simple than former mechanism.

The embodiment of the utility model keystone configuration is as follows: the structure embodiment of duplex flywheel 1 sees Fig. 3: ratchet holder 14 is tightened on the front-wheel hub, in two grooves on the ratchet holder ratchet 15 and spring 16 is housed.Flywheel 19 and 20 inner edge have the ratchet of equal number, and outer rim respectively has two annular grooves, has aperture between two grooves.The side that two flywheels are adjacent has rolling groove, some steel balls is housed in the groove weares and teares in relative rotation to reduce by two flywheels.There is tab 18 in the ratchet holder outside, and both sides are assembled duplex flywheel location by some steel balls 21 with limit lid 17 and finished.

The connection structure embodiment of crank and steel rope etc. sees Fig. 4: the transverse tube place of handlebar 4 is welded with crank 3, and its two ends have been screwed adjust bar 22, changes the arm of force length of screw hole position scalable crank.The adjust bar end is hinged with pull bar 23, steel rope 2 is from a certain end pull bar of crank, in flywheel one annular groove, behind 1 to 2 circle, pass aperture 24 between two grooves and enter in another annular groove, link to each other through the pull bar of pull back spring 25 again with the crank other end in the same way around 1 to 2 circle.The steel rope of flywheel 19 around to seeing B-B, the steel rope of flywheel 20 around to seeing C-C.Can find out among the figure when handlebar 4 reciprocally swingings, the also reverse reciprocally swinging of two flywheels, and the driven front-wheel advances.Steel wire penetrating aperture 24 and be pressed into two trench bottoms after curved the zigzag shown in the D-D, thereby be locked in the bending place, in case steel rope skids in groove during transmission.

The connection structure embodiment of steel rope and pull bar sees Fig. 5: steel rope adopts the standard front brake cable of bicycle, an end that has cylindrical block embeds in the skewed slot 28 of pull bar 23 heads, one end hook of spring 25 is gone into the aperture 29 of tie rod end, the other end hooks the aperture of screw 26 heads, and another root steel rope is compressed by screw 26 after walking around the aperture that the later end of flywheel passes circular nut 27.
