Curved load support for use on a vehicle

An assembly for mounting a container on the rear of a vehicle, the assembly comprising:

• a single support bar extending from a receiver hitch on the rear of the vehicle
• the container comprising a container base and a container lid;
• a channel extending into a bottom surface of the container base between a front and a rear face of the container base and spaced from opposite sides of the container base;
• a notch extending along the front face where the front face intersects the bottom surface, the notch extending transverse to and laterally beyond the channel;
• ears at each side of the channel protruding into the notch but not into the channel and extending below the bottom surface of the container base, with aligned holes extending through the ears, the notch being wide enough to provide clearance for insertion of a pin through the holes in the ears;
• the container being mountable only on the single support bar attached to the vehicle and extending through the channel with the pin extending through the bar and into the holes in the ears to secure the container to the support bar.

A method of mounting portable container assembly, on a vehicle for transporting the portable container assembly with the vehicle, comprising the steps of:

• attaching a support bar to a hitch receiver on the vehicle so that that support bar extends horizontally from the vehicle to a point spaced from the vehicle;
• tilting the portable container assembly with one end tilted upward;
• aligning a downwardly facing channel on the portable container assembly with the support bar with the channel initially extending at an angle relative to the support bar;
• rotating the portable container assembly to an elevated horizontal position, with a point of engagement of the channel with the support bar acting as a fulcrum, until the channel is axially aligned with the support bar;
• sliding the channel mounted on the container assembly along the support bar until the support bar extends through a majority of the channel's length;
• and
• fastening the container assembly to the support bar by pinning a pair of ears on the portable container assembly adjacent to and spaced from the channel and extending from the bottom surface so that the portable container assembly may be transported by the vehicle.
