Abstract:
1. A folding golf cart, comprising a frame including two main support rods, which are positioned apart and substantially parallel; a front wheel; and a mechanism used for displacing the front wheel between a stretched in-use position and a folded position as well as for holding the front wheel in position; the displacing mechanism including: (1) two locating members respectively secured to lower ends of the main support rods; each locating member having first and second engaging trenches on an inward side thereof; each locating member having a connecting hole between the first and the second engaging trenches, which hole has a pivotal portion, and a limiting portion communicating with the pivotal portion; each locating member having first and second curved guide spaces on the inward side, which communicate with the first and the second trenches respectively; (2) a front wheel support, on which the front wheel is supported; the front wheel support having two connecting bars projecting sideways from two lateral sides thereof; the front wheel support having two engaging pegs projecting sideways from the lateral sides; the front wheel support being arranged between the locating members at an upper portion thereof with the connecting bars being respectively held in the connecting holes of the locating members; the connecting bars and the limiting portions of the connecting holes having such a shape that the front wheel support can't turn relative to the locating members when the connecting bars are held in the limiting portions of the connecting holes; the connecting bars being capable of turning relative to the locating members when they are held in the pivotal portions of the connecting holes; the engaging pegs having such a shape as to fit the engaging trenches; and (3) two covering members respectively positioned over upper and lower sides of the upper portion of the front wheel support; the covering members being secured together to form a housing, in which the upper portion of the wheel support is held, and from which the connecting bars and the engaging pegs project out; the engaging pegs being going to be fitted in the engaging trenches of the locating members as soon as the front wheel support is linearly displaced relative to the locating members so as to fit the connecting bars into the limiting portions of the connecting holes, preventing the front wheel support from being angularly displaced relative to the locating members; the engaging pegs being going to be apart from the engaging trenches as soon as the front wheel support is linearly displaced relative to the locating members so as to relocate the connecting bars in the pivotal portions of the connecting holes, allowing the front wheel support to be angularly displaced relative to the locating members; the front wheel will be held in the stretched in-use position as soon as the engaging pegs of the front wheel support are respectively fitted in the first engaging trenches of the locating members, and the connecting bars in the limiting portions of the connecting holes; the front wheel will be held in the folded position as soon as the engaging pegs of the front wheel support are respectively fitted in the second engaging trenches, and the connecting bars in the limiting portions of the connecting holes.
