Technical field
The present patent application is to divide an application April 13 2010 original application day, former denomination of invention " a kind of quick release pedal device without instrument " for application number CN201010161406.X.
The present invention relates to quick release pedal device, particularly a kind of quick release pedal device without instrument.
Background technology
Now, the energy total amount in the whole world reduces day by day, the oil price promotion, and the public more and more favors in the vehicle green, environmental protection.Bicycle stands in the breach, green, environmental protection, can also body-building.The free public bicycles of the now numerous and confused release of various places government is mixed public transit system, vigorously advocates Green Travel, and this policy can also play the effect of obviously releasing the pressure in the crowded period of traffic peak, and bicycle has become working clan's new lover.Folding bicycle is very popular, and the folding bicycle of many patterns has been arranged on the market.Two hang-ups that the volume of present bicycle is perplexing people all the time are: 1, handlebar; 2, stretcher.How to reduce the transverse width of bicycle, receive much concern always.If can solve, men and women, old and young's bicycle of so any style, just all very convenient in storing and having carried.Now, the Patent Application Publication file of the home and abroad that can find in folding pedal plate and crank field just reaches pieces of writing up to a hundred.
The collapsible transverse width of vehicle body that can allow of pedal is less, has saved that the space is easy to deposit simultaneously, packing etc.In the bicycle field, crank is called " the crank outside " towards a side of step tread plate, and crank is called " crank is inboard " towards a side of car beam.In the present existing technology, the anchor fitting of detachable pedal all is positioned at the crank outside, namely is positioned at a side of pedal, and this set brings unsafe hidden danger, and the complex structure that generally seems, cost are high.In the Chinese patent file of CN200820134551.7, a kind of " Rapid dismounting device for pedal " disclosed, this device arranges conjunction 2 between crank shaft and crank, this conjunction tail end is connected in crank hole, front end sleeve connects crank shaft, and side arranges functional hole 22 and a series of parts and controls and block or unclamp crank shaft thereon in addition, and this device has progressive with comparing before, but part is more, and the complicated assembling that is difficult for seems; It has obviously reduced intensity and the safety of axle in the crank shaft radial aperture; In addition, its control setup is arranged on the crank outside, be that crank is towards a side of step tread plate, people are in the process of riding, this control setup may be suspended to the bottom of s trouser leg, and may because other unexpected touchings are unclamped device, for example be stepped on by sole, more can add the pedal resistance, even cause potential safety hazard.In addition, direction of operating is also kind not to the utmost beautiful.In the US Patent of US5586472, " detachable bicycle pedal mounting structure " disclosed, its structural principle and shortcoming and aforementioned Chinese patent are similar, do not give unnecessary details.In the U.S. Patent application file of US2003/0033902A1, " retractable structure bicycle pedal " disclosed, it is slotted at crank tapped bore side, and adjunction attaching parts, so that pedal integral body can realize 90 degree upsets to upside, but it has reduced intensity and has greatly increased the processing and manufacturing difficulty at crank tapped bore side fluting, attaching parts is arranged at the crank outside, may be because unexpected touching is unclamped device.
Be in the Japanese Patent Publication file of 11-208564 at publication number, " bindiny mechanism of a kind of crank and pedal shaft " described, it has an anchor fitting, this barrel-shaped anchor fitting wraps the crank outside, inboard and crank lower end, the part that is positioned at the crank inboard at this anchor fitting arranges latching device crank shaft is fixed, and should be fixed in crank by barrel-shaped anchor fitting with the pedal receptor simultaneously.The distinct disadvantage of this mechanism is, barrel-shaped anchor fitting has increased thickness and the width of crank, in the process of riding, people's pin or the bottom of s trouser leg certainly will have larger probability to scrunch or be suspended to the part that barrel-shaped anchor fitting is positioned at the crank outside, and be to be installed on the part that barrel-shaped anchor fitting is positioned at the crank inboard simultaneously to the latching device of crank shaft tail end, like this, under repeatedly impacting, latching device may get loose, and causes potential safety hazard.Moreover, except upside, this barrel-shaped anchor fitting all may be subject to the impact of external force on all the other five faces, and reliability falls greatly.
In addition, be that 2009-073364 and publication number are in the Japanese Patent Publication file of 2005-145080 at publication number, described a kind of anchor fitting, they all have with aforementioned Japanese patent and disclose similar barrel-shaped anchor fitting, so identical shortcoming is arranged, repeats no more.And these the two pieces apparatus structures of showing are complicated, are not suitable for industrialized batch manufacturing and application.
The folding bicycle production and marketing merchant of global maximum over 30 years, our company be by unremitting research and experiment, finally makes a breakthrough in that quick release pedal is technical.At present, whole world bicycle output surpasses 1.1 hundred million, and China is well-known bicycle manufacturing and use big country, accounts for more than 70% of world wide production.And the folding pedals technology is used at huge large-tonnage product like this, certainly will produce very huge social and economic effects.
In the prior art, they have a hypothesis, are exactly that fastening force must be very large, and this is and a difference in essence of the present invention.Calculate and the proof of experiment through theoretical, we find, columniform pedal pivot pin is inserted on the crank in the bigger hole, and when angle and the level of pedal produces 25 when spending, pivot pin still can not skid off in the hole.And 20 degree be Regular Bicycle when riding one be bordering on maxim.In other words, attempt the component of pedal force that pivot pin is extracted, the friction force that produces each other less than inwall in pivot pin and the hole.Two power all are directly proportional with pedal force.In other words, actual crank shaft tightens up the tighten up power of required strength in the prior art, simultaneously the also power that the tightens up size in the general impression of people.This finds that the present invention is had important inspiration.
