Definitions
- This invention relates to a tricycle having left and right front wheels and rear wheels.
- a bicycle is provided with cranks having pedals on both the left and right ends of the crankshaft, the crankshaft is rotated through the crank, and the drive sprocket provided on the crankshaft is rotated to rotate the chain.
- the driven sprocket provided on the rear wheel hub is rotated, and the rear wheel is rotated to travel forward.
- the bicycle can rotate the crankshaft continuously via the crank and has high exercise efficiency, but it is necessary to place the front wheel at a position that does not interfere with the circular movement of the crank, and the wheelbase is inevitable And the rear wheel diameter increases.
- the overall length is too large to travel around the crowd, about 190 cm, and two wheels when traveling at low speed. There is a risk of instability, and there is a risk of falling and damaging the steering wheel to avoid danger.
- the upper body is leaning forward and the line of sight is moving forward and downward, so the front of the front wheels is slightly seen.
- the left and right pedals are alternately depressed to reciprocate the left and right cranks over a certain angular range, so that the crankshaft is rotated and the driven sprocket is moved via the drive sprocket and chain provided on the crankshaft.
- a variant bicycle that rotates and rotates the rear wheel to run forward, but in order to reciprocate the left and right cranks up and down alternately, it is necessary to swing the body alternately left and right and move the weight It lacks stability and has a large exercise load, making it difficult to use for a long time.
- the present invention has been made in view of such problems, and is formed in a compact size, can easily change the front and rear direction, and can stably turn a road or the like with its line of sight facing away.

- a spring 443 that is twice the length corresponding to the rotation angle of the movable sprocket 441 is extended against the urging force, and one end is attached to the rear stay 28.
- the fixed second chain 443 is pulled through the guide sprocket 442 and the sprocket 44 and moved. For this reason, in FIG. 4, the guide sprocket 442 and the sprocket 44 are rotated counterclockwise as the second chain 444 moves, and the movable sprocket 441 is rotated clockwise.
- the first crankshaft 41 to which the sprocket 44 is connected and the drive sprocket 43 connected to the right end portion of the first crankshaft 41 are set in the same direction as the rotation direction of the sprocket 44 and the rotation angle. Rotate the same angle as.
- the movable sprocket 441 pulls and moves the second chain 443 that is twice the length corresponding to the rotation angle around the axis of the second crankshaft 42. Even if the rotation angle is small, the second chain 443 can be moved greatly to rotate the driving sprocket 43 through the sprocket 44 and the first crankshaft 41, and the driving sprocket 43 and the driven sprocket 431 can be rotated. In combination with the reduction ratio, the rear wheel WR can be greatly rotated to travel forward a sufficient distance.
- the tricycle 1 is moved forward by repeatedly depressing the kick lever 45 via the pedal 451 to rotate the second crankshaft 42 and then releasing the foot to return to the original position. Can be made.

Can not. For this reason, the direction of the front-back direction cannot be changed by rotating a rear wheel with a drive sprocket and a driven sprocket in a backward direction like a normal bicycle. For this reason, when the traveling direction of the tricycle 1 is changed back and forth, the head pipe 24 is tilted forward and the rear wheel WR is lifted off the ground, and then turned left or right around the one front wheel WF. Just do it. As a result, even in a narrow place such as a narrow road, the traveling direction can be easily changed back and forth so as to change the direction of the carry bag with casters.
- the main frame 23 can be rotated around the shaft 21a extending in the front-rear direction with respect to the front frame 21 via the connecting pipe 24a.
- an urging force acts so that the holding spring 241 on the other side is pulled and returned to the substantially vertical position.
- a fixing member is provided between the head pipe 24 and the front frame 21 as shown in FIG. It is preferable that 242 be detachably fixed.
- the fixing member 242 for fixing the head pipe 24 to the front frame 21 may be removed.
