Abstract:
1. A golf cart front-wheel collapsing device comprising: two parallel lower tubes fixed under a golf cart frame and having a lower end bent forward; two stationary annular gears having a hole for said lower tubes to pass through down; a rotary cylindrical gear positioned between said two stationary annular gears, a coil spring respectively fitted between each said stationary annular gear and said rotary cylindrical gear; a switch fixed in one of said two stationary annular gears and having a lateral elongate bar passing through said lower tubes, said two stationary annular gears and said rotary cylindrical gear, said two coil springs positioned between said two stationary annular gears and said rotary cylindrical gear and passed through by said elongate bar; a front wheel positioned below said rotary cylindrical gear; handling said switch engaging and disengaging of said two stationary annular gears with and from said rotary cylindrical gear so as to enable said front wheel folded in the space between said two lower tubes in collapsing said front-wheel collapsing device into a small size for convenience of storing and carrying a golf cart provided with said front-wheel collapsing device; at the same time said front-wheel collapsing device having an angle-adjusting function for said front wheel for fixing said front wheel at one of many angles against the ground, said front-wheel collapsing device also having the function of adjusting the height of the grip of a golf cart for suiting to users of different body heights; wherein, said rotary cylindrical gear has a cylinder extending down, and said cylinder receives a wheel supporter of said front wheel therein and said wheel supporter is secured stably therein by two V-shaped springs.
