Title:
SHOCKLESS BICYCLE
Document Type and Number:
Japanese Patent JP2017165385
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that a generally commercially available bicycle keeps impact or the like relaxed only by air pressure filling the tube in a wheel tire and by springs under a saddle and it has to be said that a further improvement is presently impossible on feeling that a further improvement in comfortableness is necessary because impact or vibration gives a considerable discomfort sense to a person boarding in accordance with a speed when a bicycle travels over the curb of a road or the boundary between a driveway and a sidewalk though a considerable comfort travel is possible when traveling over a paved road in a recent urban area.SOLUTION: This invention to improve comfortableness realizes a more comfortable travel by attaching an impact-relaxing mechanism or device which copes with irregularities or projections of a road to travel over while focusing on a present bicycle's frame structure along with a bicycle's frame to improve problems by remarkably modifying a conventional bicycle's structure.SELECTED DRAWING: Figure 1
