Title:
STEP RIDE-OVER MODIFIED ECCENTRIC WHEEL AND MOVING DEVICE USING STEP RIDE-OVER MODIFIED ECCENTRIC WHEEL
Document Type and Number:
Japanese Patent JP2020142730
Kind Code:
A
Abstract:
To provide a wheel with a simple structure that can smoothly ride over a step with small force without using a complicated machine mechanism as it is difficult to rive over a slight step with wheels having outer peripheries fixed circularly.SOLUTION: Not with a wheel whose outer periphery is fixedly circular, but with a modified eccentric wheel 1 that is provided with a plurality of projections 5 in an elliptic shape at an outer periphery of a hub and deformed with force that the projections in the elliptic shape receive from the step so as to produce effect decreasing the radius of the wheel, effect dividing the step into two steps is generated, thereby making it easier to smoothly ride over the step with smaller force than a circular wheel having its outer periphery fixed.SELECTED DRAWING: Figure 1
