Title:
RIDING WHEEL BARROW HAVING STRUCTURE THAT PEDAL TORQUE FOR ROTATING WHEEL IS TRANSMITTED TO WHEEL VIA SPEED CHANGE GEAR TO INCREASE THE NUMBER OF WHEEL REVOLUTION ABOVE PEDAL REVOLUTION
Document Type and Number:
Japanese Patent JP2016074400
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make the running speed of a riding wheel barrow almost the same as that of a two-wheeled bicycle, and to keep handling or sizes unchanged with a general wheel barrow.SOLUTION: A planetary gear 2 is disposed and coupled on a pedal shaft 4 with a planetary gear support tool 9 to fix a sun gear 3 to a wheel hub 10 and installed on the pedal 4 via a wheel hub bearing 11. A planetary gear 1 is fixedly placed on a frame 14 with a planetary gear fixture 6 so that the center may be coincident with the top of the pedal 4. Therefore, the running speed can be raised by increasing the speed of the rotation of a tyre 15 with a planetary type speed change gear built in a wheel barrow, so that the external dimension can be configured by keeping unchanged with a general wheel barrow.SELECTED DRAWING: Figure 1
