Abstract

A retractable tow hook assembly is connected with a rectangular storage container having a vertical ramp end wall hingedly connected at its bottom edge with the container for displacement about a horizontal pivot axis from an initial vertical closed position downwardly toward an inclined loading position in engagement with the ground. The tow hook assembly includes a support plate that is externally connected with the container adjacent the hinge connection, and a hook member that is displaceable relative to the support plate between an upwardly extending towing position for engagement by the loop of a towing cable when the ramp wall is in the vertical position, and a non-obstructing downwardly-displaced retracted position when the ramp wall is in the downwardly inclined loading position. A stop arrangement prevents displacement of the tow hook member beyond the extended position.
