  • Patent number: 5431472
    Abstract: A pickup truck side rail apparatus includes paired front and rear rail members which are pivotally mountable to opposed sidewalls along a truck bed. The rail members are stored in lowered positions in which they extend longitudinally above and parallel to the sidewalls. They are vertically spaced from the sidewalls to form longitudinal side rails above and along the sidewalls. The rail members are pivotal to upright positions. In their upright positions, the rail members extend vertically from the front and rear ends of the opposed sidewalls. A pair of overhead cross-bars can be mounted between the transversely aligned rail members when in their upright positions. The overhead cross-bars extend transversely above the pickup truck bed to form an overhead rack for carrying lengthy objects above the truck bed and cab.
