Abstract:
A mechanical litter stick comprising:a main staff having an upper hand-stock portion for operator handling and extending axially to a lower spike comprising a shank having a sharp tip; a mechanism attached to the main staff having an actuator in the proximity of the hand-stock portion facilitating concurrent one-handed staff-handling and actuator-actuation, said mechanism further having first and second output ends and being operative such that actuation of the actuator produces corresponding movement of the output ends between respective activated and de-activated states; a wiper structure disposed in a wiping arrangement with the spike shank whereby relative movement between the spike shank and the wiper structure can produce a wiping effect to push off debris previously impaled and otherwise stuck on the spike; first and second drive shafts having origins linked respectively to the mechanism's first and second output ends and extending to terminations which for the first drive shaft is characterized by the spike and for the second drive shaft the wiper structure, wherein the drive shafts are supported relative to the main staff for opposite extension and retraction strokes whereby mechanism actuation from the de-activated state to a given actuated state produces extension of the wiper structure concurrently with retraction of the spike and thereby the relative movement between the spike shank and wiper structure that produces the wiping effect.
