Abstract

PROBLEM TO BE SOLVED: To improve the feeling of stability and comfort during the traveling by lowering the saddle position to the regular level of a chair, and mounting a chair back, and prevent the change of the shape accompaying it from impairing the speed performance of a bicycle. SOLUTION: A forward chain 3 and a rear chain 4 are connected to each other by a gear 5 for chain connection in which two chain rings are combined with each other to form an interlocking chain, and a forward gear 6 and a rear gear 12 installed above a small front wheel 1 are connected to each other by the interlocking chain. A saddle 8 is installed to the level immediately above the rear chain, and a chair back 9 is mounted therebehind.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle that can be driven with a comfortable ride.

[0002]

2. Description of the Related Art In a conventional bicycle, a pedal side gear and a rear wheel side gear are connected by one chain.

[0003]

In the above technique, the pedal position is almost fixed at a position below the saddle between the front wheel and the rear wheel, and it is necessary to provide the saddle at a correspondingly high position. For this reason, a sense of stability was poor, and the bicycle had to be tilted when the bicycle was temporarily stopped at a traffic light or the like, and one foot had to be placed on the ground in an unstable posture.

[0004] The present invention lowers the saddle position to the height of a normal chair and attaches a backrest to enhance a sense of stability and comfort during running, and that the shape change accompanying this does not impair the speed performance of the bicycle. Aimed at.

[0005]

The two front and rear chains are connected by a chain connecting gear having a plurality of chain rings to move the position of the pedal above the small front wheel and reduce the position of the saddle to approximately half that of the prior art. I lowered it to height and attached a backrest.

[0006]

[Function] Since the saddle position is low, it is possible to ride only by straddling the center and lowering the hips. When starting, start by putting one foot on the pedal and kicking. During running, rotate both feet on the pedals and kick them alternately. If you kick the pedal strongly, the reaction from the backrest works, so you can accelerate or climb uphill without changing your riding posture.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An interlocking chain is formed by connecting a front chain 3 and a rear chain 4 with a chain connecting gear 5 in which two chain rings are combined, and a front gear 6 and a rear gear 12 installed above small front wheels are interlocked. Connected with a chain. At this time, the rear chain was substantially horizontal, and the front chain was inclined and connected to the front gear. The saddle 8 was set at the height just above the rear chain, and the backrest 9 was attached behind it. The rear wheel 2 was the same size as the conventional one and the derailleur 11 was attached so as not to reduce the speed performance. Furthermore, since the face was turned upward, a detachable hood 10 that served as a sunshade and a rain shield was attached.

[0008]

The main effects of the bicycle are as follows. (B) The driver can drive in a comfortable position supported by the backrest. In particular, it is possible to easily keep the bicycle stopped in the driving posture. (B) The force of kicking out the foot can be effectively applied to the pedal only by the reaction effect of the backrest portion, and it is not necessary to stand up or to lean forward as in the past when climbing or accelerating. (C) Since the line of sight when approaching the vehicle approaches the road surface, it is possible to enjoy a more speedy driving than before. (D) Since the riding position is low, a hood for sunshade or rain can be easily attached.

Claims (1)

[Claims] 1. A rotation of a pedal installed above a small front wheel by a pair of interlocking chains formed by connecting two front and rear chains at a certain angle by a chain connecting gear having a plurality of chain rings. A bicycle that has a mechanism to transmit power to the rear wheels and has a driver seat in the center of the body with a backrest that is high enough to reach the ground with both feet.
