Abstract
A sliding jack post stand for a trailer is capable of movement in either of two directions by application of downward force on a lever by an operator standing on one side of a trailer to be moved. A low friction plate is mounted above and spaced from a ground plate on an intermediate spacer and support plate. A slider having parallel side edges bent to enclose opposed side edges of the low friction and support plates in sliding relation supports the lower end of a trailer jack post. The slider has a fulcrum located opposite a series of nests formed in the base plate. The base plate also has a fulcrum located opposite a series of nests formed in the slider. Movement in a first linear direction is accomplished by a force applied downwardly on the handle of an articulated lever placed against one fulcrum and one of the series of nests. Movement in a second linear direction is accomplished by a force downwardly on the handle of the lever placed against the other fulcrum and one of the other nests thereby minimizing the opportunity for back injury.
