Abstract
The present invention provides a folding bicycle, in which both sides of its rear wheel have a chain wheel and a chain respectively, the pedal crank takes axle of the rear wheel as fulcrum to pull the chain and drive the flywheel, its body is divided into two parts: front part and rear part, it can be folded back through a shaft, its structure is simple, the body can be made from plastic, so that it is light, cheap, and convenient.
Description
The present invention relates to a kind of collapsible bicycle that has leverage.
The existing history for a long time of the widespread use of standard bicycle, but because this bicycle volume and weight is bigger, be not easy to fold, and will use great deal of steel, vehicle body processing is also pretty troublesome, bring a lot of inconvenience for production and use, in order to make bicycle structure more compact, I have applied for patent No. 92207702, but because the transmission device friction force is big, center of gravity partially after, can not fold, promote and get up to have very big difficulty.
The collapsible bicycle that has leverage that the purpose of this invention is to provide a kind of compact conformation, the problem that it can solve effectively, and above-mentioned transmission device friction force is big, center of gravity is back partially, can not fold.And vehicle body can adopt the plastic material manufacturing easily.
The object of the present invention is achieved like this: a chain flying wheel respectively is installed, respectively with a chain engages in the trailing wheel both sides.Chain upper end links to each other with the chain of opposite side through pulley by belt, and the chain lower end is walked around to support and turned to sprocket wheel and crank to join, and making foot-operated and crank composition one is the leverage of fulcrum with the rear axle.Vehicle body is divided in two parts, and the two connects by folding rotating shaft, and can fold mutually, with the latching device locking of band spring.
The present invention is owing to the type of drive that adopts the direct conduction chain of crank, so transmission device is very simple; Because vehicle body is shorter, thus the plastic material manufacturing can be adopted, handling ease, cheap, complete vehicle weight is also very little, can fold in addition, therefore, uses, deposits all very convenient.
The concrete structure of invention is provided by following examples and accompanying drawing thereof.
Accompanying drawing is the lateral plan according to the folding lever bicycle of the present invention's proposition.
Describe the concrete structure and the service condition of the folding lever bicycle that proposes according to the present invention in detail below in conjunction with accompanying drawing.
In this embodiment, 14 is chain, it and chain flying wheel 15 engagements that are installed in trailing wheel 19 both sides, chain 14 upper ends in both sides link to each other by pulley 8 through belt 13, the lower end is walked around the support that is positioned on the back vent 6 and is turned to sprocket wheel 12 and crank 17 to join, make foot-operated 18 and crank 17 form, be the leverage of fulcrum with rear axle 16.When firmly making foot-operated 18 to move downward, crank 17 is a conduction chain 14, drives flywheel 15, wheel 19,20 ahead runnings simultaneously, the foot-operated also while upward movement under the traction of belt 13 of wheel 19 opposite sides, foot-operated 18 so pump, and car promptly constantly moves ahead.11 is front body, and 2 is the back vehicle body, and front body 11 is " recessed " font, and back vehicle body 2 is " protruding " font, and the two links to each other by folding rotating shaft 3, and back vent 6 uses bolt 7 to be connected with back vehicle body 2.Folding latching device is positioned at front body 11 right sides, is made up of rack type dead bolt 9, spring 10 and gear 4 and turn-knob 5, and rotation turn-knob 5, gear 4 are promptly stirred dead bolt 9, and saddle is sat 1 and is installed on the vehicle body 2 of back.
