Abstract
The utility model relates to a laborsaving bicycle with a multi-angle rotation gear. The length of a pedal arm 2 is 40 - 80 cm, a pedal 1 is arranged on one end of the pedal arm, the other end of the pedal arm is slidingly assembled on a bicycle bracket 8 and is connected with a slide bar 3 through a pin 5, and a pallet 12 is provided at one end of the slide bar 3 which is assembled on the middle axle 10 of a chain plate 6 which is arranged between the chain plate 6 and a ratchet wheel 7. The ratchet wheel 7 is fixedly mounted on the middle axle 10 and an offset spring component 4 is provided on the pedal arm 2. When the pedal 1 is stepped alternatively by feet, the bicycle can continuously operate and run. As adopting the long pedal arm and the multi-angle rotation gear, rider feels more comfortable and convenient when in cycling.
Description
Technical field
The utility model relates to non-motorized vehicles, particularly a kind of improvement design-calculated bicycle that carried out.
Background technology
Bicycle pedals and chain dish constitute lever construction.According to the laborsaving principle of lever, when by bike just can be laborsaving during greater than the chain dish radius that is equivalent to resistance arm as the foot-operated arm lengths of power arm, and the long more bicycle of riding of foot-operated arm be just laborsaving more.But, utilize the foot-operated arm of lever principle lengthening to make labour-saving while, the also problem that can bring the speed of a motor vehicle to slow down by bike.
Summary of the invention
The utility model has carried out improving design to the labour-saving bicycle of existing bicycle and the foot-operated arm of lengthening, and a kind of times labour-saving bicycle of angle rotating mechanism that has is provided, and purpose is can save muscle power when allowing people ride bicycle, and the speed of a motor vehicle is also unlikely simultaneously slows down.
For laborsaving by bike, the length of said bicycle pedals arm 2 is chosen for 40～80cm, and the one end is equipped with rides 1, and the other end is slidedly assemblied on the vehicle frame 8.Foot-operated arm 2 links by pin 5 and slide bar 3, constitute so-called times angle rotating mechanism: as can be known by angle in circular segment number of degrees theorem, article one, arc right angle in circular segment equal it half of right central angle, promptly when foot-operated arm 2 turns over an angle, pin 5 will slide in the chute 11 of slide bar 3, and the angle that slide bar 3 is turned over is twice than the angle that foot-operated arm 2 turns over, because slide bar 3 links with chain dish 6 by axis 10, ratchet 7 and ratchet 12, so the angle that chain dish 6 turns over is always stepped on the angle that arm 2 turns over than limb and is twice, thus the speed of a motor vehicle when having guaranteed to ride.

The specific embodiment
Now in conjunction with the accompanying drawings 1, accompanying drawing 2 specifies implementation process of the present utility model.
The length of the foot-operated arm 2 of this example is 50cm, links by pin 5 and slide bar 3.Slide bar 3 one ends are equipped with ratchet 12, and slidable fit is on the axis 10 of chain dish 6, between chain dish 6 and ratchet 7.Ratchet 7 is fixedly mounted on the axis 10.Also establish resilient elastic component 4 on the foot-operated arm 2, returning power elastic component 4 among Fig. 1 is a tension spring, and its end is fixed on the foot-operated arm 2, and the other end is fixed on the vehicle frame 8.Return power elastic component 4 and also can make the jump ring structure.
When riding, only using foot is trampled downwards and is ridden 1, and foot-operated arm 2 rotates slide bar 3 by pin 5, and by chain dish 6 rotations that ratchet 12, ratchet 7 drive axis 10 and link with it, drives to move ahead by chain 9 again.Pine is during pin, returns power elastic component 4 and makes foot-operated 1 original place of rebounding, and simultaneously, ratchet 7 does not produce propulsive effort during with ratchet 12 counter motions.Bipod is alternately trampled and is ridden 1, bicycle is turned round continuously move ahead.Because adopted long foot-operated arm and times angle rotating mechanism, so, allow the people feel easily quick when riding.
The utility model also is particularly suitable for being installed on the tandem bicycle.
Claims (1)
