Abstract
The utility model relates to a labour-saving bicycle, comprising a handle 3, wheels 1, a vehicle frame 5 and a central axis 4. Both ends of the central axis 4 are respectively fixed with a ratchet wheel 6; pedals 2 are fixedly arranged on the outer ring of the ratchet wheel 6; an upper and lower adjusting oscillatory device is arranged between the vehicle frame 5 and the pedals 2. Therefore, the pedals 2 can not be switched to the position perpendicular to the horizontal plane and the effective torque of the pedals 2 is enlarged so as to save labor for riders. The utility model can be used for tricycles.
Description
The utility model relates to a kind of bicycle.
The present bicycle that uses of the public is that the keep left rotation of right pedal drives sprocket rotation, and sprocket wheel drives wheel by transmission devices such as chain, flywheels, thereby makes bicycle to overtake.Angle about this bicycle between two pedals is 180 °, promptly at grade, when pedal forwards the position vertical with horizontal surface to, because its moment is very little, the rider is pedaled felt effort.
The purpose of this utility model provides a kind of rider of making and pedals more labour-saving bicycle.
The purpose of this utility model is realized by following technical proposals, the bicycle of forming by handlebar, wheel, vehicle frame, pedal, sprocket wheel, axis, fixedly mount a ratchet respectively at the two ends of axis, pedal is fixed on the outer ring of ratchet, the inner ring of ratchet is fixed on the axis, is equipped with between pedal and the vehicle frame to make the pedal device of suitable swing up and down.
Above-mentioned make pedal up and down the device of suitable swing by lever, connecting rod, prolong the pedal rod that pedal extends back and form, lever is fixedly mounted on the standpipe of vehicle frame, the two ends of lever are hinged with an end of left and right sides connecting rod respectively, and the other end of left and right sides connecting rod is hinged with left and right sides pedal rod respectively.
Make pedal up and down the device of suitable swing can realize that also it comprises pulley and soft band by following technical scheme, pulley is fixedly mounted on the last pipe of vehicle frame, soft band passes pulley and is enclosed within on the pulley, the two ends of soft band are separately fixed on the pedal.
Owing to adopted technique scheme, two pedals of bicycle are swung in 45 °-135 ° angular range, can not made pedal forward the position vertical to, compare with existing bicycle with horizontal surface, increased the effective torque of pedal, thereby it is more laborsaving that the rider is pedaled.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the front view of bicycle.
Fig. 2 is the partial right side view of bicycle.
Fig. 3 is the front view that adopts the bicycle of pulley and soft band.
Fig. 4 is the partial left side view that adopts the bicycle of pulley and soft band.
From Fig. 1, Fig. 2 as can be known, the bicycle of forming by handlebar 3, wheel 1, vehicle frame 5, pedal 2, sprocket wheel 7, axis 4, fix a ratchet 6 respectively at the two ends of axis 4, pedal 2 is fixed on the outer ring of ratchet 6, the inner ring of ratchet 6 is fixed on the axis 4, like this when pedal 2 when direction is rotated, the inner ring of ratchet 6 is rotated together, and during towards backward rotation, then inner ring can not rotate.In order to make pedal 2 suitable swing up and down in certain angular range, promptly when right pedal 2 time to lower swing, left foot is pedaled 2 upwards swings, therefore on bicycle, be provided with the device that makes pedal suitable swing about in the of 2, this device comprises lever 8, connecting rod 9, prolong the pedal rod 10 that pedal 2 extends back, lever 8 is fixedly mounted on the standpipe of vehicle frame 5, the two ends of lever 8 are hinged with an end of left and right sides connecting rod 9 respectively, the other end of left and right sides connecting rod 9 is hinged with left and right sides pedal rod 10 respectively, and be equipped with in the both sides of lever 8 strong points and make the locations 11 of lever 8, thereby two pedals 2 suitable swing in 45 ° of-135 ° of angular range about making by the certain angle swing.During use, pedaled following time when right pedal 2, can drive sprocket wheel 7 and rotate, at this moment right pedal bar 10 is upturned, right connecting rod 9 is up pushed up, up swing with lever 8 one ends that right connecting rod 9 is hinged, and lever 8 one ends that are hinged with left connecting rod 9 are toward the bottom, thereby make left connecting rod 9 toward pressing down, make left pedal rod 10 toward lower swing, then left foot is pedaled 2 up swings, because ratchet 6 has been installed, pedals 2 when left foot and can not drive sprocket wheel 7 when up swinging and rotate.Same principle is pedaled 2 when left foot and is pedaled following time, and the transmission by lever 8, connecting rod 9 up swing right pedal 2, and back and forth swing continuously of pedal 2 so just can make sprocket wheel 7 unidirectional rotation, thereby 1 rotation of drive wheel makes bicycle to overtake.
By Fig. 3, Fig. 4 as can be known, the device of pedal suitable swing about in the of 2 can be realized by another technical scheme, it comprises that a pulley 13, one are soft and is with 12, pulley 13 is fixedly mounted on the last pipe of vehicle frame 5, softly be with 12 to pass pulley 13 and be enclosed within on the pulley 13, soft two ends with 12 are separately fixed on the left and right sides pedal 2, are provided with locations on 12 soft being with, and two pedals 2 are swung in 45 ° of-135 ° of angular range about making.During use, pedaled following time when right pedal 2, drive sprocket rotation, be with 12 to make left foot pedal 2 upwards swings by soft, because ratchet 6 has been installed, left foot pedals 2 when upwards swinging, and can not drive sprocket wheel 7 backward rotation.Same principle is pedaled 2 when left foot and is pedaled following time, drives sprocket wheel 7 and rotates, and makes upwards swing of right pedal 2, and back and forth swing continuously of pedal 2 so just can make sprocket wheel 7 unidirectional rotation, rotates thereby drive wheel 1, makes bicycle to overtake.
The utility model also can be used for three-wheel vehicle.
