Description

Works to operate the pedals up and down between the 3-wheeled bike}

The present invention has one wheel at the front, two wheels are arranged at the rear side, and the driving rotary shaft is mounted in the horizontal direction perpendicular to the vehicle body direction at the vehicle front end support section, and the two pedal operation hypothesized from the vehicle front end to the rear of the vehicle body. A drive system that rotates the drive rotation shaft clockwise by reciprocating up and down to obtain propulsion force, a power transmission unit that transmits the rotational force of the drive rotation shaft to the rear wheel, and a steering wheel operation when the steering wheel is operated when the bicycle enters the bend. It is a three-wheeled bicycle that is equipped with a body tilt device that causes the body to tilt toward the bend.

Conventional three-wheeled bicycle is a configuration that obtains propulsion by rotating the crank pedal by manpower by installing a crank pedal on the front wheel or the rear wheel, so it is inconvenient to take a lot of power when going up a slope, and the body does not tilt when entering a curved road. The person who boarded in so that the weight of the human body to bend so that the change of direction is achieved, the operation was difficult to be difficult.

The present invention is a three-wheeled bicycle that eliminates the inconvenience as described above when the driving force is generated when the driving force is less power and bends easy to use and easy to use when entering the bent paint.

The present invention is provided with a pedestal (1a) in the upper rear of the vehicle body, the pedal is installed on the rear end of the vehicle body at the front end by installing a drive rotary shaft (2) in the horizontal direction perpendicular to the vehicle body direction on the fork support shaft (1b) body It is equipped with a drive shaft drive device to rotate the drive shaft in a clockwise direction by reciprocating the operation up and down to transfer the rotational force generated from the drive shaft to the rear wheel to obtain propulsion force and to the vertical fixed plate fixed to the rear part of the body. Two horizontal members installed at right angles are installed side by side on the upper and lower sides so that the middle part is connected to the vertical fixing plate by a hinge axis, and vertical connecting pieces are arranged on the outer ends of the upper and lower horizontal members to connect the upper and lower horizontal members to the hinge axis on the vertical connecting pieces. Connect the connecting plate from one vertical connecting piece to the surface of the vertical fixing plate, and place it at the position corresponding to the center of the vertical fixing plate. If the operating handle is rotated by passing the shaft of the operation handle installed on the vehicle body with the nut and the moving nut with the nut and the male rod connected with the articulated connector, the connecting plate moves up and down from the reference point according to the direction in which the male screw rod rotates. As both ends of the furnace member are raised and lowered, the vehicle body is inclined so that it is easy to change directions and make safe driving.

According to the present invention as described above, sitting on the pedestal (1a) by stepping on the pedal operation (3) using both feet to move from the top to the lower end between the pedal operation (3a) of the support groove (1f) of the vehicle front end support (1e) Is hinged to the hinge shaft 3b, and is connected to the drive rotary shaft 2 as a one-way bearing (a one-way bearing uses a commercially available bearing that transmits rotational force in a clockwise direction). When the operation between the pedals is moved downward, the operation tape 20 is released and the operation rotation shaft 2 'is rotated clockwise because the operation tape 20 is rotated clockwise and the chain pulley Power is transmitted to the transmission shaft 4 through the chain 23 and the chain belt, and power is transmitted to the rear wheel through the chain pulley and the chain belt mounted on the transmission shaft 4 and the rear wheel 5a. Rotate clockwise When the force between the pedal operation reaches the bottom dead center and the force applied between the pedal operation is removed, the spring device 21 made of the elastic tape mounted on the operation rotating shaft is restored and the operating rotation shaft is reversed. It is wound again to prepare for the next operation. In this process, the one-way bearing installed between the drive shaft and the drive shaft rotates power only when the drive shaft rotates clockwise to rotate the drive shaft clockwise.

In addition, the operating rotary shaft is installed on the left and right of the driving rotary shaft can be operated alternately between the pedal operation is possible to continuously push.

And the steering wheel 9 of the present invention is connected to the steering operation between the steering wheel (1d) and the timing belt 12 of the upper end of the fork support shaft (1b) for supporting the front wheels is formed gear (9c) on the outer surface of the shaft (9a) Therefore, when the steering wheel is rotated, the steering operation of the fork support shaft is interlocked to steer the direction of the front wheel, so that the steering wheel can be conveniently operated in the direction to be driven by manipulating the steering wheel.

Meanwhile, in the present invention, the vertical fixing plate 6 is integrally mounted to the bottom of the vehicle body on which the seat is mounted, and the middle portions of the two horizontal members 7 and 7a are connected to the hinge shafts 7b. Vertical connection piece 70, 71 is connected to the hinge shaft (7c) (7d) is connected to the rear wheel support piece, connecting plate 84 with a nut 85 from the vertical connection piece (70) (71) to the vertical fixing plate surface ) Is installed and the nut is a vertical screw rod (10) connected to the bottom of the steering wheel is screw-assembled, so if the moving nut is moved upward from the reference by turning the steering wheel right, the right vertical connecting piece becomes higher and the left and vertical connecting piece becomes lower. When the body is inclined to the right side, when the operating handle is turned to the left, the opposite phenomenon is formed and the body is inclined to the left side. The operation in which tilting is to take place.

Therefore, it is easy to change the direction of the curved road while driving the bicycle, and when the steering wheel returns to the normal position, the connecting plate moves to the neutral position, and the two horizontal members are in balance to maintain the vehicle body correctly. As the power is assisted, the return can be made quickly so that the driving effect can be achieved.

Therefore, since the present invention is developed, it has the advantage of making the three-wheeled bicycle propelled by operating the pedal operation up and down safely and conveniently,

In particular, by achieving the body slope with the two horizontal members used in the present invention, even if the rear wheel spacing of the narrow bicycle there is an advantage that can secure the driving stability line, the upper and lower two horizontal members have a distance between the axis of the intermediate support shaft As described in FIG. 10 (a) (b), by shortening the distance between the shafts of the support shafts at both ends, when the vehicle body is inclined, the inclination angle of the vehicle body can be large and the inclination angle of the wheel can be small, so that a narrow body such as a three-wheeled bicycle There is an advantage in being able to prevent the risk of overturning the body in the bike to maintain.
