Abstract
The utility model relates to a flexible labor saving bicycle. A bicycle frame is a single beam forming a big arc shape, a front wheel is smaller than a rear wheel, a small front fork is provided with a spring for damping, a rear fork is vertical with the ground, one end is fixed to a rear wheel shaft, and the other end is connected with a bicycle saddle; The utility model has the advantages of short bicycle body, portability, labor saving for ridding and stability and flexibility for ridding. The utility model is an ideal walking tool.
Description
The utility model belongs to a kind of bicycle.
At present, the most of straight tube triangle combination vehicle frame that adopts of coventional type bicycle, vehicle body is long, vehicle seat center and trailing wheel misalignment one segment distance, except that cyclist's weight produces the positive pressure the trailing wheel center, an also additional moment, therefore, the load that car travels is big, hard to pedal, simultaneously because the restriction of front and back wheel diameter forces vehicle body longer, if testis and prostate are produced friction and extruding when riding at a distance for a long time, cause the generation of some diseases, certainly front and back wheel all adopts the minor diameter wheel, can shorten vehicle body, but this small-wheel bicycle speed can be corresponding slack-off.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, thereby providing a kind of rides that speed is fast, flexible, health care safety, light and handy laborsaving, the bicycle being convenient to move.
The purpose of this utility model realizes in the following way:
This bicycle has handlebar (1), vehicle frame (2), little front fork (3), back vent (14), vehicle seat (8), trailing wheel (11) and front-wheel (13), wherein: vehicle frame (2) is a single-beam great circle arc, front-wheel (13) is little front-wheel, have elastic force extension spring (6) and lever slide block (5) about little front fork (3), back vent (14) is perpendicular to ground, its upper end is vehicle seat (8) fixedly, is connected the two ends of hind axle (12) about the lower end.
Little front fork (3) connects hollow tubular, respectively there are two about lever slide block (5), little front fork top slidably is connected with the lever slide block, position, lever slide block (5) top, the left and right sides does not have to connect about circular hole and little front wheel spindle and cooperates, another top, the lever slide block left and right sides connects elastic force extension spring (6), and elastic force extension spring (6) other end is fixed on the little front fork (3).
The utlity model has following advantage:
Move the formula exterior design after adopting single-beam circular arc vehicle frame, little front-wheel damping and vehicle seat, the preceding wheel diameter of car is littler than back wheel diameter, the front and back wheel distance between shafts shortens, on this external little front fork slideway is housed, elastic force extension spring bumper, make cyclist's center of gravity on hind axle, thereby can reduce the drive torque of trailing wheel, and preceding wheel diameter is little, can shorten vehicle body, because of on little front fork bumper being housed, it is steady, safe, flexible, in light weight that car is travelled, owing to adopt such scheme, laborsaving, the health care of riding, fast, convenient in carrying, be a kind of desirable walking-replacing tool.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the utility model constructional drawing.
In Fig. 1: (1) handlebar; (2) vehicle frame; (3) little front fork; (4) left and right sides pin is stared at; (5) lever slide block; (6) elastic force extension spring; (7) little front wheel spindle; (8) vehicle seat; (9) back underframe; (10) mudwing; (11) trailing wheel; (12) hind axle; (13) front-wheel; (14) back vent.
In the embodiment shown in fig. 1: the back vent lower end of vehicle frame be bearing on the wheel shaft two ends of trailing wheel (11) and back vent (14) perpendicular to ground, the upper end captive joint vehicle seat (8) of back vent (14), cyclist's weight is by vehicle seat (8), back vent (14) is bearing in the wheel shaft two ends of trailing wheel (11), people's center of gravity is dropped near the wheel shaft center of trailing wheel (11), people's weight does not produce the additional resistance square to the wheel shaft center of trailing wheel (11), or resisting moment is minimum, therefore garage crosses in the journey, certain angle is arranged to pedal, laborsaving more comfortable than ordinary bicycle, do not oppress prostate, the diameter of front-wheel (13) can be much smaller than the diameter of trailing wheel (11), for example, 26 inches of back wheel diameters (about 65 centimeters), preceding wheel diameter can be made 12 inches (about 36 centimeters), vehicle body just can shorten about about 50 centimeters than ordinary bicycle, obviously move facility downstairs on, vehicle body shortens simultaneously, car weight alleviates, move more favourable to weak women and children, the front-wheel reduced does not change the speed of bicycle, because the speed of a motor vehicle is decided by driving wheel, i.e. and the diameter of trailing wheel (6).
Claims (2)
1. flexible labour-saving bicycle, have handlebar (1), vehicle frame (2), little front fork (3), back vent (14), vehicle seat (8), trailing wheel (11) and front-wheel (13), it is characterized in that: vehicle frame (2) is single fine strain of millet great circle arc, front-wheel (13) is little front-wheel, have elastic force extension spring (6) and lever slide block (5) about little front fork (3), back vent (14) is perpendicular to ground, and its upper end is vehicle seat (8) fixedly, is connected the two ends of hind axle (12) about the lower end.
2. bicycle according to claim 1, it is characterized in that: little front fork (3) connects hollow tubular, respectively there are two about lever slide block (5), little front fork top slidably is connected with the lever slide block, position, lever slide block (5) top, the left and right sides does not have to connect about circular hole and little front wheel spindle and cooperates, another top, the lever slide block left and right sides connects elastic force extension spring (6), and elastic force extension spring (6) other end is fixed on the little front fork (3).
