Foot actuated ladder latching device for a tilting type ladder rack
A ladder latching device for a tilting ladder rack includes an inner extrusion for clamping to the load supporting member of the ladder rack. An outer extrusion is slidably mounted on the inner extrusion. The outer extrusion carries a treadle and ladder rung engaging stop. Between the two extrusions are a toothed rack and a gas spring. The outer extrusion carries a pivotable, spring-biased lever having a tooth for selectively engaging the toothed rack for releasably locking the stop at a desired location relative to a rung of a ladder being unloaded as the outer extrusion is made to slide by applying foot pressure on the treadle. Thus, a ladder may be lowered along the load supporting member until the ladder's feet engage the ground as the stop disengages from its place on a ladder rung.
