CN2235936Y - Low-saddle bicycle with directional layshaft - Google Patents

Abstract

The utility model relates to a low-saddle bicycle with directional a layshaft, which is modified on the basis of an ordinary bicycle. A saddle seat of the low-saddle bicycle can be moved backward and downward to the position where a rider's two feet touch down. A drag-link mechanism is arranged between the directional layshaft and the upper part of a front fork. The directional layshaft is provided with directional handles. A front and a back wheels are provided with damping devices. A seat can be folded, turned over and laterally put on a beam of a bicycle frame. The utility model has the technical proposal that vertical riding is changed to sitting riding, and original downward pedalling is changed to forward pedalling. The utility model has the advantages of comfortable sitting posture, not easy fatigue, and rider can touch down by double feet at any time. The bicycle enhances the security.

Description

The low seat bicycle that the direction countershaft is arranged

A kind of low seat bicycle that the direction countershaft is arranged, the national uses field of vehicles.

Bicycle is through 100 years of development, because its simple structure, cheap, be the preferable vehicle that the both urban and rural residents rides instead of walk and smallclothes transport, particularly in automobile exhaust pollution environment serious day by day today, development and improve the bicycle function, structure is used positive social effect is arranged to enlarge the spring.

Also there are many problems in the bicycle that the common people that sell on the present market generally ride.

1. saddle is narrow, and the buttocks bearing surface is little, and is uncomfortable.

2. cushion height, instability, dangerous.

3. when riding, forward lean bends over to bend forward the back of the body, and the weight of upper body is mainly at palm and buttocks, and the time of riding is long slightly, and palm, waist, buttocks all have pain and uncomfortable sensation in various degree.

4. the face that keeps out the wind of health is big, and the resistance when advancing is also bigger.

5. the spring below tire and cushion, there is not other damping facility.

In order to solve the problem of these existence, the inventor has carried out bigger change to existing bicycle.The utility model is a kind of low seat bicycle that the direction countershaft is arranged.Its objective is to the common people provides a kind of safe in utilization, comfortable, and the resistance in advancing is little, the new bicycle of good damping effect.

Used technical scheme: the utility model be a kind of the direction countershaft is arranged, be provided with before and after shock absorption device, the folding low seat bicycle of seat.Be on the basis of the ordinary bicycle of forming by vehicle frame, handlebar, front and back wheel, saddle etc., to change a social system to form.

A. saddle backward, being moved downward to the bicyclist can the position that contact to earth of both feet, and vehicle seat is backed seat;

B. at direction countershaft of distance health appropriate location weldering, between direction countershaft and front vehicle fork top installing by the making of parallel-crank mechanism principle by two horizontal steel discs and two drag link mechanisms that pull bar is hinged.

Be fixed on the horizontal steel disc of drag link mechanism installing this steering handle of steering handle (bearing circle also can) on the direction countershaft.

Be provided with shock absorption device in front and back wheel, this shock absorption device is made of the spring shaft that penetrates conduit, spring and pole, and front-wheel pole is a triangle pole.Rear wheel fulcrum bar is a back vent.

Its seat base plate and back board are laterally hinged with, and can fold, and this base plate is contained on the rotary hinge plate that is anchored on the bicycle beam.

Brake adopts line to stop, and move with handlebar its position.

The improved bicycle of the utility model changes vertical riding to sitting posture and rides, by original pedal downwards to change into forward pedal comfort for sitting posture, good damping effect, indefatigability.Bicycle rider can contact to earth by both feet at any time, has improved safety.

Now in conjunction with the accompanying drawings with preferred embodiment.

Fig. 1 is the scheme drawing of the utility model embodiment.

The same Fig. 1 of Fig. 2, the structure of local repressentation shock absorption device and saddle horse.

Fig. 3 is the organigram of trailing wheel yoke.

Fig. 4 is the decomposition chart of Fig. 3.

Fig. 5 is the organigram of seat.

Fig. 6 is a seat folded structure scheme drawing.

The utility model is to improve to constitute on the ordinary bicycle of being made up of vehicle frame, handlebar, front and back wheel, saddle etc., and these improvement comprise:

One. the change of cushion:

A. common saddle is removed, changes into chair type or simple and easy sofa-type.

B. backward, displacement downwards changes vertical riding to sitting posture and rides with seat 1.(by original pedal downwards to change into forward pedal.) change like this after, reduced height, being seated also can land by both feet, has improved safety factor.Because seat moves backward, vehicle frame also need extend back accordingly.

Two. the change of steering handle:

Because seat is to backward shift, steering handle widens from the distance of health, and hand just can't reach original steering handle, and this just need carry out big change to steering handle;

Claims (3)

1. the low seat bicycle that the direction countershaft is arranged is made up of vehicle frame, handlebar, front and back wheel, saddle etc., it is characterized in that:

A. saddle backward, being moved downward to the bicyclist can the position that contact to earth of both feet, and vehicle seat is backed seat;

B. at direction countershaft of distance health appropriate location weldering, between direction countershaft and front fork top installing by the making of parallel-crank mechanism principle by two horizontal steel discs and two drag link mechanisms that pull bar is hinged; Install steering handle on the direction countershaft, this steering handle is fixed on the horizontal steel disc of drag link mechanism.

2. the low seat bicycle that the direction countershaft is arranged according to claim 1, it is characterized in that: its front wheel spindle is provided with triangle pull bar shock absorption device, and this shock absorption device is by the spring shaft that penetrates conduit, and spring and triangle pole constitute; Its hind axle is provided with common shock absorption device, is made of spring shaft, spring, back vent.

3. the low seat bicycle that the direction countershaft is arranged according to claim 1, it is characterized in that: its seat plate and back board are laterally hinged with, and this base plate is contained on the rotating hinge plate that is anchored on the crossbeam.
