<p>PURPOSE: A bicycle buffering device is provided to improve buffering efficiency by manufacturing a body of a bicycle supporting front and rear wheels with elastic material and structure. CONSTITUTION: A bicycle body is composed of a rear frame(38) connected to a rear wheel(20); a front frame(31) connected to a handlebar housing(13); a vertical frame(39) connecting front and rear frames, and having a saddle in the upper part; and a horizontal frame(37) connecting the vertical frame and the front frame. The front frame is made of elastic material against impact, weight of a passenger and tare of the bicycle, and formed in parabolic structure. The front frame is partitioned to absorb shock, and composed of a main elastic shaft(32a) in the middle and auxiliary elastic shafts(32b) in both ends. The impact is absorbed efficiently with placing the auxiliary elastic shaft at both sides of the main elastic shaft. The rear frame is made of flexible material to endure against shock, tare of the bicycle and the weight, and formed in parabolic shape.</p> |
