Abstract
The utility model provides a novel bicycle without power aid, which belongs to an improved bicycle. The bicycle is provided with an upper frame girder and a lower frame girder, wherein the front ends of the upper and the lower frame girders are provided with front forks; the front and the back ends of the lower frame girder are respectively provided with a front wheel and a back wheel; the middle part of the lower frame girder is provided with a centre shaft. Chains are arranged on a chain wheel which is fixed to the centre shaft and another chain wheel which is arranged on the back wheel, and a pedal is also fixed to the centre shaft. A free wheel is also arranged on the centre shaft, and is engaged with a segment gear which is arranged at the lower end of a saddle bracket. The middle lower part of the saddle bracket is hinged at the front end of the bracket, and the back end of the bracket is fixed to the lower frame girder. A spring is arranged on the upper frame girder at the back side of the saddle bracket. The bicycle can cause the gravity of a rider to become one part of forward dynamic force for the bicycle, thereby, the forward speed is improved and the physical strength of the rider is saved. The utility model has the advantages of simple structure, easy manufacture and low cost.
Description
Technical field
The utility model provides a kind of improved bicycle.
Background technology
Set a roof beam in place on having on the existing bicycle and under set a roof beam in place, the upper and lower front end of setting a roof beam in place is equipped with front fork, the front fork upper end is equipped with handlebar, under the front and back ends of setting a roof beam in place be separately installed with front-wheel and trailing wheel, under the middle part of setting a roof beam in place axis is installed, on the sprocket wheel of fixing on the axis and another sprocket wheel on the trailing wheel chain is arranged, also be fixed with pedal on the axis, trailing wheel is generally flywheel.The bicycle of this structure is to pedal pedal by riding with the person with both legs, thereby drives sprocket rotation and then drive that another sprocket wheel on the trailing wheel advances, and its shortcoming is the effort of riding, and speed of advance is slower.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel unpowered morpet, to improve speed of advance, saving muscle power.
The utility model is to realize like this, novel unpowered morpet, set a roof beam in place on it has and under set a roof beam in place, on, under the front end of setting a roof beam in place front fork is installed, the front fork upper end is equipped with handlebar, under set a roof beam in place before, the rear end is separately installed with front-wheel and trailing wheel, under the middle part of setting a roof beam in place axis is installed, on the sprocket wheel of fixing on the axis and another sprocket wheel on the trailing wheel chain is arranged, also be fixed with pedal on the axis, flywheel also is installed on described axis, the quadrant gear that install flywheel and vehicle seat support lower end meshes together, the middle and lower part of vehicle seat support is hinged on the front end of support, on the rear end of support is fixed on down and sets a roof beam in place, on setting a roof beam in place on the vehicle seat support rear side spring is installed.
Adopt the bicycle of said structure, can make the gravity of riding become a part of power that bicycle advances, thereby improve speed of advance, saved and ridden the person's of using muscle power with the person.Simple in structure, easy to manufacture, productive costs is low.
Description of drawings
Fig. 1 is the front view of the utility model structure.
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and principle of work.
As shown in drawings, the novel unpowered morpet of the utility model, set a roof beam in place on it has (12) and under set a roof beam in place (16), on, under the front end of setting a roof beam in place front fork (14) is installed, the front fork upper end is equipped with handlebar (13), under set a roof beam in place before, the rear end is separately installed with front-wheel (15) and trailing wheel (2), under the middle part of setting a roof beam in place axis (19) is installed, on the sprocket wheel of fixing on the axis (17) and another sprocket wheel (1) on the trailing wheel chain (20) is arranged, also be fixed with pedal (18) on the axis, flywheel (11) also is installed on described axis, the quadrant gear (10) that install flywheel and vehicle seat support (7) lower end meshes together, the middle and lower part of vehicle seat support is hinged on the front end of support (3), on the rear end of support (3) is fixed on down and sets a roof beam in place, on setting a roof beam in place on the vehicle seat support rear side spring (5) is installed.
Described spring (5) by front apron (8) and back shield (4) be installed in set a roof beam in place on, front apron and vehicle seat support (7) fit together, also has bolt adapter plate (21) in the back of back shield, regulate bolt (22) and be installed on the bolt adapter plate, set a roof beam in place on vehicle seat support the place ahead (12) also are equipped with postive stop baffle (9).Regulate bolt by rotating, promote back shield and move forward or backward, it is compressed or releasing spring, can adjust the elastic force of spring.
Vehicle seat support upper end is equipped with vehicle seat (6).Obviously, on the front and rear wheel spoke should be arranged.
Ride sit on the vehicle seat with the person after, the gravity of human body will press the vehicle seat support, making it is shaft swing with the support as lever, the swing backward of vehicle seat support upper end, the quadrant gear of its lower end is swung forward, rotates thereby drive flywheel, the rotation of flywheel just drives axis and rotates, for the rotation of sprocket wheel (17) increases power, simultaneously, the vehicle seat support is with spring application.When riding when firmly pedaling pedal with the person, the part gravity of human body will be transferred on the pedal.After the gravity that the vehicle seat support bears alleviated, spring opened, and the vehicle seat support is back into original position, and the backswing of vehicle seat support drives quadrant gear and swings backward, flywheel idle running.When riding when constantly firmly pedaling with the person, the gravity of human body just constantly shifts, thereby makes the continuous reciprocally swinging of vehicle seat support, increases power for bicycle advances, and reaches the power-assisted purpose.
