  • Patent number: 5351921
    Abstract: The invention is directed to a golf bag folding stand which has two legs pivotably fastened to a golf bag by a mount. A hinge device is fastened to the golf bag at the bottom and two connectors respectively fastened around the legs and joined by an elastic band. A spring link is connected between the connectors and a hinged movable plate on the hinge device, whereby the spring link pushes the hinged movable plate downward for allowing the legs to be automatically received to the golf bag when the golf bag is lifted from the ground. The hinged movable plate is forced to push the spring link upward as the golf bag is placed on the ground with the hinged movable plate stopped against the ground, causing the spring link to extend the legs apart from each other and simultaneously to push the legs away from the golf bag.
