  • Fast adjust trailer jack
    Patent number: 9308894
    Abstract: A fast-adjust trailer jack has three telescoping tubular segments, an upper, an intermediate and a lower. A lead screw is used to operatively couple the upper to the intermediate and a tension spring is coupled between the intermediate and the lower to normally urge the retraction of the lower into the intermediate. A spring-biased pin and hole based detent mechanism is employed to allow setting of the degree of extension of the lower tubular segment with respect to the intermediate tubular segment.
