Compact bicycle with reciprocating pedals

FIELD: transport engineering; bicycles with crank-and-connecting rod transmission.

SUBSTANCE: proposed bicycle contains frame 1, driven sprocket 5, driven sprocket 2, chain, steering column 6 with handlebar. Reciprocating pedals are secured to levers to of driven sprocket 2 through rigid tie-rods 3. Devices to bring levers of driving sprocket 2 out of extreme point is hinge-secured on frame 1 and on rigid tie-rods 3. Frame 1 of bicycle provides distance of 10 cm between front and rear wheels in operating position of bicycle. Compactness of bicycle at shipment is provided by pressing of pedals to tie-rod 3.

The invention relates to a Bicycle crank transmission and reciprocating moving levers.

Known vehicle, where applied, the reciprocating movement of the pedals and frame, providing close the distance between the front and rear wheels in the working position of the bike (see FR 876054). The drawback of this bike is that the device that allows you to move the pedals reciprocating consists of many parts, and each part has weight and cost. Also complex design.

Known vehicle, where applied, the reciprocating movement of the pedals and there is a means of bringing the levers of the leading stars of the extreme points (see DE 4404831 A1)is selected as the closest analogue. But this drive is placed on the frame of an ordinary Bicycle or scooter, which is a classic way of transmission is more acceptable.

The objective of the invention is to create a bike is simple in construction and convenient in operation, compact, with which you can easily enter in public transport and in which the weight of the person would be the main driving force.

This is ensured by the fact that the bike with the reciprocating movement of the pedal contains a frame, driven and led by the sprocket, chain, steering column the steering wheel, when this pedal to the levers sprocket mounted through hard thrust, and the frame and rigid rods pivotally attached to the output medium of the levers sprocket from the extreme points, and the frame of the bike provides a distance of 10 cm between the front and rear wheels in the working position of the bike. The compactness of the bike during its transportation is provided by the application pedals to pull.

On the accompanying drawings depicts a Bicycle.

Figure 1 - view of the bike from the side.

Figure 2 - connecting the drive sprocket and the hard thrust with pedals.

1 - frame, 2 - sprocket levers, 3 - hard thrust with pedals, 4 - output medium of the levers sprocket of the extreme points ("leash"), 5 - ring sprocket, 6 - wheel with the steering column.

The bike works as follows: you take the bike behind the wheel, puts his foot on the pedal hard thrust 3, which is in the upper position, and presses his weight on the pedal. The force from the pedal through the rigid rod 3 is the lever sprocket 2 and the chain driven sprocket 5. The bike rolled. When the pedal hard thrust 3 from efforts feet will reach the lowest point, the second lever sprocket 2 raised to its extreme upper position your pedal with hard thrust 3 and the lead 4 output levers sprocket of the extreme points will lead her C the axial line, laid vertically through the shaft sprocket 2, thereby deciding the question of extreme points. At this point, the second pedal hard thrust 3 is in its extreme upper position. Leash 4 this pedal hard thrust 3 puts this pedal in front of the vertical centerline of the shaft sprocket 2. Next person presses his foot on the pedal. The cycle was repeated. This method leads to solve the issue of extreme points. The leads 4 are attached to the frame 1 and to the hard pull with 3 pedals articulated. So, man, stepping from foot to foot their weight makes the bike is rolling speeds three speeds pedestrian. When a man's weight enough to move the bike, and it happens when lifting or on rough road, then the man pulls the wheel 6 on itself. The muscular effort of the arms attached to the person's weight and this is the generalized force presses the pedal down hard thrust 3. Increase efforts is considerable.

The simple design of the bike and its mobility is obvious. While riding standing more natural. In emergency situations this bike safer. People without interference becomes your feet on the ground, leaning on the wheel 6. At the entrance to public transport it is necessary to turn the steering wheel 6 180° and pedals attach to the draft.

1. The bike with the reciprocating movement of the pedals, containing a frame (1), driven (5), leading (2) sprocket, chain, steering column (6) with the steering wheel is, when this pedal to the levers sprocket (2) are mounted through a hard thrust (3)and the frame (1) and rigid rods (3) hinged tool output levers sprocket (2) of the extreme points, characterized in that the frame (1) bike provides a distance of 10 cm between the front and rear wheels in the working position of the bike.

2. The Bicycle according to claim 1, characterized in that the compactness of the bike during its transportation is provided by the application pedals to pull (3).
