A bin tunnel with collapsible sides

摘要

A bin tunnel (6) having collapsible sides is used with a truck box (4) of a truck to load content into the truck box (4) from a bin that is sized to fit within the bin tunny (6) when the bin tunnel (6) is in an open position. When the bin tunnel (6) is in a closed position a footprint of the bin runnel (6) is very small compared to the open position because the sides (16) of the bin tunnel (6) are retracted. The footprints can be less when the bin funnel (6) is in the closed position from thirty percent of the footprint of the bin tunnel (6) in the open position. When the bin tunnel (6) is closed, the contents of the truck box (4) are secure as the space inside of the closed bin tunnel (6) is too small to allow access to the interior.
