Description

Bike to hand and foot {BICYCLE DRIVING HAND AND FOOT}

TECHNICAL FIELD The present invention relates to a bicycle, and more particularly, to a bicycle going to a hand and a foot which can be selectively operated using hands and feet.

Recently, as interest in the environment and health is increasing, there is an increasing number of people who commute to work or travel on bicycles, which not only have no environmental pollution caused by emissions, but also provide aerobic exercise for the human body.

In general, the bicycle body is composed of a plurality of frames, the upper front of the body is provided with a handle, the upper and rear rear of the body is provided with a saddle, and the front and rear frames of the body is provided with a front wheel and a rear wheel.

The right frame of the bicycle is provided with a driving sprocket fixed to the pedal, a driven sprocket installed on the rear wheel, and a driving part consisting of a chain fastened to the driving and driven sprockets.

The user can ride on the saddle by stepping on the pedestal with the force of the foot to rotate the drive sprocket, and rotate the driven sprocket connected by the drive sprocket and the chain to drive the rear wheel and rotate the steering wheel by hand to adjust the direction.

However, since these bicycles are driven by rotating the rear wheels by stepping on the lungs with just the power of the feet, they can be somewhat unreasonable and have a low propulsion force. It also has the disadvantage of uncertain operation and significant load on the power transmission process.

Therefore, not only the feet but also the hands move together to increase the driving speed and propulsion of the bicycle, and not only the movement of the arms together with the legs, but also the use of either the hands or feet when one of the legs or arms is tired. The situation is required to develop a bicycle that can run even.

Accordingly, an object of the present invention is to provide a bicycle that can be moved by moving the hands and feet together to increase the driving speed of the bicycle, which can be selectively operated using the hands and feet, and which can be easily operated by anyone.

Bicycle to the hands and feet according to an embodiment of the present invention for achieving the above object, the handle lever is rotatably installed on both sides of the body, the lower end of the handle portion is installed extending the handle support with the front wheel axially coupled And, one end is connected to the handle support and the other end constitutes the main frame with the rear wheel axially coupled, the foot sprocket is connected to the drive sprocket driven by the rotation of the pedal and the driven sprocket installed on the rear wheel by chain, The part is characterized in that the drive sprocket driven by the rotation of the handle lever and the handle drive unit is connected to the driven sprocket installed on the front wheel by a chain.

The present invention can increase the running speed of the bicycle by moving the hands and feet together, and when either one of the legs or arms is tired, it can run using only one of the hands or feet, the movement of the arm together with the legs It can be combined, and anyone can operate easily.
