The present invention relates to a vertical operation device of a motorcycle pedal improved to allow the rider to step on the footsteps with the highest amount of exercise almost equal to the weight, so that the wheels can be driven effortlessly as a lever.

In the conventional bicycle, the pedal moves in a circular motion, and the movements are changed at 10 o'clock, 3 o'clock, and 4 o'clock and 5 o'clock, respectively, and the motor must be rotated 180 degrees so that the opposite pedal can carry momentum. And the pedal is so small that when you put your foot on the floor, you can easily feel tired because you touch only a part of the foot. It is published in the Japanese Utility Model Publication, which is designed to convert the rear wheels and pedals into rotational movements as a linkage mechanism, while the left and right pedals are attached to the guiding members which are mounted on the bicycle hurdle to swing back and forth. Only one pedal was operated vertically and the interlock mechanism was rotated. The Japanese Utility Model Publication No. 55-83184 discloses a bicycle, in which the left and right pedals are reciprocated vertically and the pedals are attached to the guide member so that the rear wheel rotates on the pedals and the interlock mechanism. It is a configuration that consumes a lot of power and has no practical use. It had no advantage over ordinary bicycles except the effect of simply pedaling vertically.

Unlike the conventional ones, the present invention forms a pedal like a lever and moves up and down alternately, so that even if the movement width is a little, by stepping on both pedals alternately, the maximum amount of exercise can be obtained and unnecessary exercise (action) When described in detail by the accompanying drawings as having been devised to reduce the radius as follows.

The rear wheel (4) is fixed to the bicycle body (1) and the wheel support (2) by the shaft (5), and the support plate (6) is formed on the saddle support (3) by chain gears (9) (9 ') and guide grooves. (8) (8 ') and roller (12) chain gear (13) is equipped with a pedal device (7) guided by the guiding device (10) (11) guided wire (14) and chain gear (17) (17 ') and chains (15) and (16) interlock with each other in the pedal arrangement (7) to constitute a lag gear and to actuate the pedal's sliding by spring elasticity. The support pieces 22, 22 'and the pin shaft 23 on both sides of the disc 20 connected to each other by forming an internal gear difference 19, 19' on the inward faces of the chain gears 17, 17 'coupled to each other. Springs 25, 25 'to the clasps 24 and 24' adhered to each other, and the curved working piece 26 is pinned to the window 27 to the clasps 24 and 24 '. ), And then, the rear end of the rear wheel support (2) is formed with the support (29), and the rear end of the lever (31) (31 ') with the footrests (32, 32') attached to the front end. "After adhesion to the inter-connection with a guide (33, 33 bolt 30, 30 'for the connection to the hayeoseo a) the connecting pin (34).

Referring to the operation effect of the present invention as described above are as follows.

First, the rear rear wheel support (2) extends to the rear end and constitutes a support (29) for supporting both extension parts, and then guide paper on the rear side of the lever (31) (31 ') with the footrest (32) (32') attached to the tip. (10) (11) is completed by fixing the flow between the connection 33 is connected to the connecting pin 34.

Next, the lower side of both guide papers (10) (11), which are guided to the groove of the pedal device (7), is connected to the wire (14) to be wound around the roller (12) to act, and the guides (10) (11) Chain gears (17) (17) which are connected to the rear wheel (4) shaft (5) by winding the chain gears (9) (9 ') staked on the support plate (6) by connecting the chains (15) and (16) on both sides. ') Was connected to the chain gear (13) configured in the pedal unit again connected to the device.

When driving, as illustrated in FIG. 3, when the footrest 32 on the left side of FIG. 1 is pressed down, the lever 31 descends from the coalescence bolt 30 and at the same time, the descendant 10 is also lowered. The chain 15 is pulled and rotates the chain gear 17 at the same time. At this time, while the internal gear 19 of the chain gear 17 is integrally rotated, the latch 24 formed on the disc 20 is pushed by the elastic force of the spring 25 and caught by the internal gear 19 and at the same time the disc 20 As the shaft (5) rotated on the disc 20 is rotated while the rear wheel is also rolled.

When the clasp 24 is engaged by the internal gear 19, the lower end of the clasp 24 pushes the curved working piece adhering to the hatch 27 with the pin 28, like the seesaw, starting from the pin shaft 23. The lower end of the clasp 24 'on the opposite side (right side) is pushed (marked with a dashed line) so as not to be connected to the internal gear 19' of the right chain gear 17 'so that the sound is not generated when the right side is idling.

On the contrary, when the right footrest 32 'is stepped on, the above action is reversed, and the wire 14 assists the guide 10 and 11, and the chain gear 13 supports the rear group 16. It is wound up to smoothly assist the operation of alternating chain gears 17 and 17 '.

In this way, the present invention is extremely limited in the range of motion of the pedal pedal of the rider to obtain the maximum amount of exercise with a small amount of motion compared to the conventional 360 ° rotation or 180 ° rotation or a wide range of the known vertical pedal It can be effective.
