  • Patent number: 5437423
    Abstract: An improved double pronged golf bag support assembly has a two pronged ground engaging element slidably disposed within an elongated tubular housing for movement from a retracted position to an extended position with the pointed end of each prong extending beyond the lower end of the housing to engage the ground at two laterally separated points. The double pronged ground engaging element consists of a single metal rod bent at its approximate mid-point with its pointed ends extending parallel to one another downwardly within a tubular housing having an oval cross section. An exterior foot pedal element affixed between the prongs above the pointed ends extends outwardly through an elongated longitudinal slot in the tubular housing body so that the double pronged spike can be driven downwardly by foot pressure on the pedal against the upward force of an expandable spring having its lower end attached to the top of the spike and its upper end affixed within the upper end of the tubular housing.
