Abstract

The utility model discloses a bicycle without seat, with a riding speed faster than existing bicycles and a strong ascending ability, and is convenient to carry, and can adapt to the road surface for existing bicycles, and can be folded to put away in an office, in a classroom, in a car, or be carried into a market, a hotel, a restaurant, or a bus, and requires no special parking place, therefore, the utility model is a good environmental-friendly transportation means, as well as a good sports equipment and an entertainment product.

Description

There is not seat bicycle fast

The utility model relates to a kind of the seat to be stepped on, and the speed that runs is fast, and gradient capability is strong, portable bicycle.

In existing bicycle, except Kickboard Scooter (is that people's a leg stands in that another leg is used for stepping on ground on the vehicle body, recoil during by foot-operated ground makes a kind of bicycle of Kickboard Scooter walking), all be to design to be grown up to be sitting in to climb up, rotate pedal with bipod in 360 ° vertical plane, make bicycle walking, design makes the car body of bicycle and car weight amount all very big like this, be not easy to carry, need a specific place to park; The moment that also has both feet to rotate pedal is to be increased to maximum gradually from 0, be reduced to 0 process so gradually from maximum again, and wheel is big and rotational frequency is little, the ability so existing bicycle is on the up grade (is that the people is when being on the up grade by bike, feel effort, maybe can not walk).

The purpose of this utility model provides a kind of no seat quick bicycle that has improved, make the people can in maximum rotation moment scope, rotate its pedal, by the speed change of change-speed box, make its speed fast than existing bicycle, gradient capability can adapt to by force sees the road surface that has bicycle to adapt to; Make its car body littler, the car weight amount is lighter, can shrink to fold, and is easy to carry, and does not need specific parking place to park.

The purpose of this utility model is achieved in that adorns an iron rope between the right and left pedal, make that left side pedal is stressed to be pivotally lowered into when equal with horizontal surface, can by the iron rope the right pedal rise to horizontal surface at 45～position at 60 ° of angles.Otherwise be pivotally lowered into when equal with horizontal surface when the right pedal is stressed, by the iron rope again left side pedal rise to from the horizontal surface position with horizontal surface at 45～position at 60 ° of angles and the two pedals moment that only just rotates when stressed being pressed downward, moment does not rotate when being mentioned by the iron rope.The rotating torque of two pedals passes to trailing wheel after by the change of a change-speed box again; Remove to sit and step on, radius of wheel is narrowed down to about 10 centimetres, it is folding that whole locomotive body can be shunk, and is easy to carry.

The utility model because do not sit is not stepped on, need the people stand on two pedals with pin with horizontal surface at 45～back and forth rotate pedal in the perpendicular at 60 ° of angles, so the people can back and forth rotate pedal in the maximum torque scope, and do not feel painstaking.Owing to be in maximum rotation moment scope, back and forth to rotate pedal.So by after the speed change of change-speed box, can make this bicycle faster than the speed of existing bicycle, gradient capability is stronger than existing bicycle; Again because pedal can only forward the position radius of wheel equal with horizontal surface to and has only about 10 centimetres, and the space of rotation is little,, can shrink folding being easy to carry and do not need specific parking place so the weight of car body and car can design very for a short time.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Figure＜1〉be outward appearance planar view according to the quick bicycle of no seat that the utility model proposes.

Describe details and function situation in detail below in conjunction with Fig. 1 according to the concrete bicycle that the utility model proposes.

This bicycle is by brake handle＜1〉threeway cover＜2〉directional lever＜3 〉. go up central siphon＜4 〉. following central siphon＜6 〉. turn-knob＜5 〉. adapter sleeve＜7 〉. damper spring＜9 〉. front fork＜10 〉. front-wheel＜11〉wait the formation heading control loop; By pedal＜17 〉. pedal＜18. iron rope＜16 〉. pedal shaft＜15 and shell＜14 in change-speed box＜figure in do not draw and gear-shift lever＜13 of change-speed box constituted power system.

Directional lever＜1〉can regulate among braking rope＜figure and not draw length, braking rope is from threeway cover＜2〉the outside pierce into, by last central siphon＜4〉and following central siphon＜6 in, from adapter sleeve＜7〉under pass, through connecting panel＜12〉the bottom, again to trailing wheel＜19〉brake＜figure in do not draw, the same with existing bicycle 〉; Turn-knob＜5〉scalable directional lever＜3 height; Central siphon under the scalable＜6〉with adjusting angle device＜8 at the angle of inclination of horizontal surface an end be fixed on connecting panel＜12 on, the other end is fixed on adapter sleeve＜7〉on; Iron rope＜16〉be connected pedal＜17 and pedal＜18 on, down forward to when equal when pedal (17) is stressed, can be by iron rope＜16 with horizontal surface〉pedal＜18 rise to horizontal surface at 45～position at 60 ° of angles; Otherwise down turn to when equal when pedal is stressed, can be by the iron rope pedal＜17 with horizontal surface〉rise to horizontal surface at 45～position at 60 ° of angles, and the two pedals moment that in the process that is raised, do not rotate; The moment of rotating two pedals is by shell＜14〉in change-speed box＜figure in do not draw pass to trailing wheel＜19 after changing; Prolong plate＜20〉just decorate and use as vehicle.

Claims (2)

1. can be portable nothing seat bicycle fast, this bicycle have two be limited in horizontal surface at 45～pedal＜17 of rotating in the vertical plane at 60 ° of angles and pedal＜18, it is characterized in that pedal＜17〉and pedal＜18 between iron rope＜16 are arranged, iron rope＜16〉and pedal＜17, pedal＜18〉constitute the propulsion source of this bicycle with a change-speed box.

2. according to right 1 described bicycle, it is characterized in that when pedal＜17 stressed down turning to when equal with horizontal surface, by iron rope＜16〉can be pedal＜18 rise to horizontal surface at 45～position at 60 ° of angles, otherwise pedal＜18〉stressed down turning to when equal with horizontal surface, can be by iron rope＜16〉pedal＜17 rise to horizontal surface at 45～position at 60 ° of angles, and the two pedals moment that do not rotate when being raised.
