Abstract
Apparatus for assisting in opening and closing the side of a truck-body is shown and described. Illustratively, a pully is mounted eccentrically on one end of the shaft to which the swingable portion of the truck roof is fixed. A system of traction cables and a tension spring combine with gravity forces acting on the pivotal lower lateral wall portion of the truck to reduce the effort needed to open and close the side of the truck.

A vehicle having a fixed central roof portion, a swingable roof portion that is hinged to the central roof portion by means of a shaft and an associated upper lateral wall portion hinged to the swingable roof portion comprising a pulley that is eccentrically mounted on the shaft about the axis of which the roof portion is swingable, a swingable lower lateral wall portion hinged to the vehicle, a traction cable connecting the lower lateral wall portion with said pulley in order to turn the pulley and the shaft and move the swingable roof portion therewith, a turnbuckle mounted eccentrically on the pulley, a tension spring attached to the vehicle, a traction cable coupling the turnbuckle to the tension spring, the turnbuckle on the pulley wheel being positioned to stress the tension spring with the lateral wall portions in the closed position, to relax the tension spring during the travel of the lateral wall portions toward the opened position, and to stress the tension spring to a maximum as the swinging movement terminates at the fully-open position.
