Abstract

The utility model relates to a bicycle ridden in an oblique lying posture. The wheel diameter ratio of the driving wheel 1 and the driven wheel 3 of the utility model is 1.3: 1. The intersection angle between a fork type beam frame 6 and the connecting line of the centers of the driving wheel 1 and the driven wheel 3 is between 10DGR and 20DGE. A supporting frame 4, a driven wheel pole support 10, a faucet handle 11 and a faucet frame 12 are orderly arranged on the driven wheel 3. The beam frame 6 and the pole support 10 are welded by corner joint by a 90DGR angle. A seat 13 whose front and back positions can be adjusted at can is fixed on the beam frame 6. The front end of the beam frame 6 is provided with a front speed changing gear 9 and pedals 7. The back end of the beam frame 6 is provided with a back speed changing gear 16 and the driving wheel 1. A gear 9 and a gear 16 are connected by a chain 5. The utility model has the advantages of comfort, labour saving, safely, flexible manipulation and high speed.

Description

Bicycle ridden in oblique lying posture

The utility model relates to a kind of non-motorized vehicles, and especially a kind of posture by bike is the bicycle of reclining type.

At present, there is following some deficiency in existing ordinary bicycle: (1) seat cushion front end extruding cyclist's perineal position can make the people feel perineal position pain for a long time by bike; (2) locations of structures of vehicle seat and handlebar, the necessary forward lean of decision cyclist, both hands are pushed down tap, and both shoulders are stressed bigger, and the time has been grown, and the sense of aching is arranged, and understeer is lived; (3) vehicle seat is bordering on vertically with foot-operated, requires great effort when riding, and speed is slow; (4) vehicle seat height, centre of body weight raises, and is unfavorable for balance, poor stability.

The purpose of this utility model is to overcome the existing existing defective of bicycle, provides a kind of ride comfort laborsaving, safety, manoeuvrable, fireballing Recumbent bicycle.

Task of the present utility model realizes in the following manner: this Recumbent bicycle comprises driving wheel, flower wheel, messenger chain, roof beam structure, foot-operated, foot-driven lever, tap frame and seat, the impeller diameter ratio of driving wheel and flower wheel is 1.3:1, the angle α of V shape roof beam structure and driving wheel and the flower wheel line of centres is 10～20 °, the flower wheel top is provided with support successively, flower wheel pole, faucet handle and leading frame, roof beam structure and pole are welded at an angle of 90, the ratio of weld nugget to roof beam structure front end distance and weld nugget to roof beam structure rear end distance is 1:2.8～3.0, seat is bolted on the roof beam structure by seat cushion board and adjusting, the roof beam structure front end is provided with preceding variable gear, foot-driven lever and foot-operated, the roof beam structure rear end is the U font, by drive sprocket axle back variable gear and driving wheel are housed, preceding variable gear is connected by driving chain with the back variable gear.

Recumbent bicycle of the present utility model has the reclining type arm-chair, thus ride comfort, and the foot-operated flower wheel top that is positioned at, ride laborsaving, manoeuvrable; At the bottom of this car seat center of gravity, easily grasp balance, and pin can step on ground at any time, safe and reliable; This car adopts change gear transmission because front-wheel is littler than trailing wheel, and promptly laborsaving, speed is fast again; In addition, this bike saddle is ridden and can be moved forward and backward, and rides so can adapt to the people of different heights, and the utility model need not increase weight, length and the cost of bicycle.

Concrete structure of the present utility model is provided by drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of roof beam structure among Fig. 1 (6) front end;

Fig. 3 is the structural representation of leading frame (12) among Fig. 1;

Fig. 4 is the structural representation of roof beam structure among Fig. 1 (6) rear end.

Below in conjunction with drawings and Examples the utility model is described in more detail.
