Title:
COLLAPSIBLE BICYCLE
Document Type and Number:
Japanese Patent JPS644587
Kind Code:
A
Abstract:

PURPOSE: To easily and quickly collapse an assembled bicycle into a compact posture by making a seat post freely oscillating with respect to a frame and providing a collar of a frame and a brace member in a freely displaceable manner along a stem with respect to a front wheel.

CONSTITUTION: In order to fold a bicycle, a stay bar 43 is pushed in and a lock for a rod 3 and the stay bar 43 is released, while a seat post 36 is oscillated forward and the stay bar 43 is lined up on the lateral of the seat post 36 by the action of a spring 48. Simultaneously, after disengaging the engagement of a stud material with a lower collar member 6 by rotationally moving a pipe material 31 by 180 degrees, the frame 1 and the brace member 14 are relatively displaced to the folding position with respect to a stem 29 by raising a collar member 26 of the brace member 14 and the collar member 6 of the frame 1 along the pipe material 31 by traction of a cable 35. A front wheel 7 is then laid over a rear wheel 27 and the seat post 36 is folded toward the front at the upper side of the frame 1.
