The support bracket is provided with a linkage driving mechanism composed of a handle bar, a saddle and pedals and directly driving a ratchet arranged on a back wheel axle by a chain or a wheel plate and a chain arranged on the wheel plate. Besides labor saving, riding the bicycle can also enable each body part to be exercised. Meanwhile, the utility model can also increase the interesting for riding the bicycle and the utility model can be simultaneously and singly used as a body building device.

Description

A kind of labour-saving bicycle

The utility model relates to a kind of by front and back wheel and the labour-saving bicycle that support constituted that is used to limit this wheel.

Bicycle is a kind of middlebrow rickshaw, it generally includes the front and back wheel that is limited by support, being provided with what be used for that staff grasps direction on the top that limits front-wheel support can only be the handlebar that sways, and a ratchet is installed in the limit of hind axle portion, and by chain fluted disc on the stretcher and ratchet are coupled together, make it form the actuating device of this car.As the pin Zhou Erfu that chooses pedals described stretcher with making, and drives ratchet and rotate with the rear wheel of this coaxial ratchet by chain, and then drives body movement.As can be seen, the power of riding this kind car people pedal stretcher just can make the car motion after must overcoming car people's gravity itself and resistances such as car and ground-surface friction force, be that the power that people's pin is pedaled stretcher back and forth is unique power of car motion, and the gravity of health is to hinder the car body main resistance that advances, so, ride this kind car and except that leg, almost can not get due exercise in other position of human body, just local support body motion, and require great effort very much; In addition,, and can not move along the working direction of car body because the unique function of handlebar of this car is to limit direction, so, can make arm stiff for a long time by bike.

Task of the present utility model provides a kind of labour-saving bicycle that the power of pedaling of the pulling force of the gravity of health and arm and pin can both be able to be become the car body onward impulse.

The utility model relates to a kind of by front and back wheel be used to limit the labour-saving bicycle that support constituted of this wheel, is equipped with on this support by handlebar, vehicle seat and interlock that stretcher constitutes and directly drive the driver train that is arranged on the ratchet on the rear vehicle shaft by chain or through a wheel disc and the chain that is installed on this wheel disc.

Described driver train comprise by pivot with its be limited on the vehicle frame and can be along the handlebar and the vehicle seat of the axial rotation of car, and stretcher, wherein, the outer setting of rotating shaft has a U-shaped frame that is limited by pivot on the handlebar, and the extended end that makes the extended end of opening direction of this U-shaped frame and stretcher top is equipped with the pull bar of flexible connection, and an end of this pull bar is connected with an end of chain, and vehicle seat is supported by a U-shaped frame, and the extended end of this U-shaped frame opening direction and the other end of described chain join, and also are equipped with and described handlebar top movable bonded assembly rod member in this end.

On the face of described support the wheel disc that is limited by pivot is installed, this is taken turns web portion and is provided with can be connected with the pull bar that the handlebar bottom flexibly connects lateral opening, and its periphery is provided with the chain that is connected with ratchet on the back wheels of vehicle axle.

The end that the described pivot that is used to limit wheel disc passes support is provided with an axle drive shaft parallel with this support, and the end of this axle drive shaft joins with the upper end of described vehicle seat and stretcher respectively by the trace that flexibly connects.

Because but the utility model all repacks handlebar, vehicle seat and stretcher into the drive element of interlock, thereby the gravity of the power that pushes away or draw of arm and health itself all can be converted into the power that turns a wheel together with the power of pedaling of pin, so, ride this kind car except that laborsaving, also can make each position of health can both obtain exercise, can also increase the interest of riding this car simultaneously; In addition, use the structure of this car, also can be made into the simple body-building vehicle that special key body utensil has the fixed position in other words.

Below in conjunction with drawings and Examples the utility model is elaborated.

Accompanying drawing 1 is the surface structure scheme drawing of an embodiment of the utility model;

Accompanying drawing 2 is surface structure scheme drawings of another embodiment of the utility model;

Accompanying drawing 3 is back views of accompanying drawing 2.

Referring to Fig. 1, it provides the schematic appearance of a kind of structure labour-saving bicycle of the utility model.This car has front vehicle wheel 2 and the rear wheel 1 that is limited by support 3, and its support 3 is normally by the polygon that rod member constituted of hollow, but anterior bow 31 double as front vehicle forks, and the axis 21 of its end and front vehicle wheel 2 joins.Other position of support 3 preferably can form the shape of a quadrangle 32 and a triangle 33, and the support 3 of this structure promptly has cooresponding stability, can limit other parts easily again.

Handlebar 4 outer setting of support 3 front portions have a U-shaped frame 41 that is limited by pivot 44, and the opening direction that makes this U-shaped frame down, its end is provided with one by pivot 43 bonded assembly pull bars 42, the other end of this pull bar also is connected by a pivot 51 with the extended end on stretcher 5 tops, and this position also is connected with an end of chain 6.Above-mentioned vehicle seat 7 is connected with a U-shaped frame 72, and this U-shaped frame also is limited to the top of support 3 by pivot 71, and the end 72 of its opening and the other end of described chain 6 are joined, and this end also is equipped with and described U-shaped frame 41 top movable bonded assembly rod members 8.

By bike the time, as long as moving handlebar 4 with hand to the health direction uses pedal stretcher 5 simultaneously, the person can stand from vehicle seat 7 naturally, and can retract chain 6 this moment; When handlebar 4 is extrapolated to health, when the health seat is on vehicle seat 7 simultaneously, just the total weight of health all can be added on the stretcher 5, and then spur chain 6 forward, wheel is rotated forward, and action can make this car continuously travel forward so again and again.

Referring to Fig. 2 and Fig. 3, it illustrates the surface structure of another embodiment of the utility model.The structure of this embodiment is same as the previously described embodiments substantially, just on a face at support 3 middle parts the wheel disc 9 that is limited by pivot 91 is installed, this take turns web portion be provided with can be connected with the pull bar 42 that the handlebar bottom flexibly connects lateral opening 92.When handlebar 4 to pulling back or when extrapolated, wheel disc 9 being rotated around pivot 91.The periphery of wheel disc 9 be equipped with hind axle on the chain 6 that joins of ratchet 10, so wheel disc 9 rotates and can drive ratchet 10 or rear wheel 1 rotates.

The other end that the pivot 91 of described wheel disc 9 passes support 3 is provided with an axle drive shaft parallel with this support 93, and the end of this axle drive shaft joins with the upper end of described vehicle seat 7 and stretcher 5 respectively by the trace 72 and 52 that flexibly connects.

When moving handlebar 4 toward the health direction, use pedal stretcher 5 simultaneously, people's health can stand by nature, this moment, arm acted on the wheel disc 9 by pull bar 42 and trace 52 to the pulling force that returns and the gravity of health, and then pulling wheel disc 9 rotates, and after this action is finished, health is downwards during seat, by trace 72 gravity of health self is converted into wheel disc 9 equidirectional turning efforts too, can promote wheel disc 9 rotates continuously, drive ratchet 10 rotations or car body simultaneously and rotate, to realize specific tasks of the present utility model.
