Pontoon boat with retractable running gear

摘要

An elongated mobile structure is provided including a body portion and an intermediate section of the body portion is provided with elongated support arm structure having one end pivotally secured to the body portion for oscillation about a transverse axis between a depending position and a generally horizontal position with the free end of the arm structure swung toward one end of the body portion or structure. The free end of the arm structure has ground engaging support wheels journaled therefrom and an elongated lever is pivotally secured, intermediate its opposite ends to the one end of the body portion for oscillation about a horizontal transverse axis and swinging between a longitudinally extending horizontal position and an upstanding position. An elongated link is pivotally connected between the lower end portion of the arm structure and the rear end portion of the lever, whereby upward swinging of the forward end portion of the lever will exert a forward pull on the lower end of the arm structure to upwardly retract the ground engaging support wheels.
