FRAME STRUCTURE OF BICYCLE
Document Type and Number:
Japanese Patent JP2018069840
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a frame structure of a bicycle attributable to a new concept of making it possible to arbitrarily adjusting the distance between a front wheel and a pedal crankshaft and the height of a steering handlebar.SOLUTION: A frame structure of a bicycle according to the present invention is such that: a wave clamping device including a safety lever is coupled and bonded to an upper surface of a seat frame interlocked with a seat tube; a clamping jaw is vertically reciprocated by interlocking a cam lever and the safety lever, and fixed to a wave shape formed on the upper surface of a top frame so that the seat frame can be located at an arbitrary position; and down frames on one and the other sides are bonded to the seat frame. A fork frame is a structure to enable adjustment of the height of a bicycle steering handlebar. The fork frame is coupled to the top frame without being welded. The down frames to which a rear wheel of a bicycle is attached reciprocally slide on the top frame, thereby enabling contraction and expansion to an arbitrary position.SELECTED DRAWING: Figure 1
