JPH10316079A - Bicycle drivable by hand force - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a bicycle that can be efficiently driven only with hand force without leg force. SOLUTION: Handlebar levers 3 laterally arranged around a bevel gear 2 built in a handlebar body 1 are direct-coupled so as to be able to steer moving the handlebar levers 3 to the right or left simultaneously while moving the handlebar levers 3 vertically to drive a bicycle. Since the handlebar levers 3 can output force if they are moved up and down with force, driving force can be obtained by moving one up while moving the other down simultaneously with the force of both hands at the time of needing strong output to start or go up an upward slope.

です．2. Description of the Related Art Conventionally, a bicycle that can be driven by hand power has been operated by raising and lowering a lever with one hand to perform another one-handed squeezing. In addition, a crank attached to a steering wheel is turned with one hand. There was a bicycle that was driven and squeezed with another hand. Both are three-wheeled vehicles with one front wheel and two rear wheels.

グです．[0005] [Embodiment of the invention] With the above configuration, the bevel gear (4) interlocked with the handle lever (3) is directly connected to the gear (5), so that the handle lever (3) is moved up and down. The bevel gear of (4) and the gear of (5) both repeat a half-turn movement to the left and right, while the chain of (6) connected to the gear of (5) repeats the forward and backward movement. (6) When the chain moves forward, the drive gear of (7) operates, but when the chain of (6) moves backward, the drive gear of (7) idles and does not operate (8). The drive gear of (7) directly connected to both sides of the drive wheel of (8) is driven forward and backward by the reciprocating motion of the chain of (6) on both sides of the drive wheel. 6) Chains are combined vertically and horizontally as necessary to fit each part gear That. And (9) is a pulley for preventing slack. (10) is a spring that pulls the pulley.

At the same time, you can move the handle lever (3) to the right or left to change direction.

And since the wheel that can speed up is larger than an electric vehicle without a license, it is not as troubled as a wheelchair.
