ABSTRACT:
A golf cart collapsible device includes a lock base provided on two parallel handle bars and on top of two parallel frame tubes. The lock base has a bar hole each at two ends for containing a spring and a first sleeve fixing around each handle bar, enabling the lock base move up and down for a limited distance along the handle bars. Each frame tube has a pivot base fixed on an upper end, and the pivot base has a center hole for a second sleeve to fit in. Each second sleeve has a guide surface communicating with the center hole. Each handle bar has a first end pivotally connected with the pivot base so that the two handle bars may be swung up for 180 from a collapsed position to an expanded position, with the lock base automatically pushed down by the springs to force its engage members fit in the second sleeves to lock the handle bars in the expanded position.
