  • Patent number: 6019567
    Abstract: A slidable load lift apparatus is selectively completely retractable into the bed of a standard pickup truck. The load lift apparatus includes a base frame member attached to the pickup truck bed, the base frame member supporting a substantially planar roller platform member slidably engaged with the base frame member. The base frame member includes a pair of elongate rail members extending in parallel along a first longitudinal axis and adapted to engage a set of roller wheels provided on the bottom of the roller platform member. A substantially planar lift platform member is operatively connected to the roller platform member through a set of parallelogram linkages which permit the lift platform to be moved between a raised position coplanar with the roller platform member and a lowered position out of the plane of the roller member for convenient loading of the lift platform at ground level.
