Abstract

The golf bag cart includes a central base, a bottom cart stand, an upper cart stand, a wheel support, a first linkage, a second linkage, and a lock mechanism. The bottom cart stand has a top end fastened to the central base, a bottom end coupled with a front wheel, and a slider. The upper cart stand has a bottom end pivotally connected with the central base. Two wheel supports, disposed respectively and inclinedly at two sides of the central base, are joined with a steel wire to form a structure similar to a triangle. The first linkage connects the upper cart stand and the slider. The second linkage connects the slider and the wheel support. The lock mechanism mounted on the top end of the slider enables the upper cart stand and the bottom cart stand to lock with each other.
