Abstract
A lifting apparatus for use in the bed of a pickup truck having a lifting bar of a generally U-shaped configuration with one side pivotally connected to a side wall of the bed of the pickup truck and an opposite side pivotally connected to another side wall of the bed of the pickup truck. A cylinder has a piston rod extending outwardly therefrom. This piston rod has an end pivotally connected to a linkage connected to the lifting bar. The cylinder is actuatable so as to move the piston rod between a retracted position and an extended position such that the lifting bar is pivotable relative to the movement of the piston rod. The linkage has a scissor-like configuration which allows the lifting bar to be stowed completely within the interior of the bed of the pickup truck.
Claims16
A lifting apparatus comprising:
- a pickup truck having a bed with a pair of side walls on opposite sides of said bed, said bed having an opening at one end and a forward wall opposite said opening;
- a lifting bar having a generally U-shaped configuration with one side pivotally connected to one of said pair of side walls and an opposite side pivotally connected to another of said pair of side walls;
- a cylinder means connected to at least one of the sides of said lifting bar, said cylinder means for pivoting said lifting bar between a first position extending outwardly of said opening of said bed and a second position stowed within said bed such that said lifting bar has an end adjacent said forward wall of said bed;
- and
- a linkage connecting said cylinder means to the side of said lifting bar generally adjacent the pivotal connection of said lifting bar to the side wall of said bed, said linkage comprising:
- a first arm having a first end pivotally attached to the side of said lifting bar, said first arm having a second end pivotally connected to said cylinder means;
- and
- a second arm having a first end pivotally connected to said cylinder means and a second end pivotally connected to the side wall of the bed.
A lifting apparatus for use in the bed of a pickup truck comprising:
- a lifting bar having a first side and a second side in parallel relationship to said first side, said lifting bar having a crossbar extending between said first and second sides at one end thereof;
- a linkage pivotally connected to at least one of said first and second sides adjacent an end opposite said crossbar, said linkage comprising:
- a first arm having a first end attached to one side of said lifting bar, said first arm having a second end pivotally connected to said piston rod;
- and
- a second arm having a first end pivotally connected to said piston rod and a second end suitable for pivotal connection to a side wall of the bed of the pickup truck;
- and
- a cylinder having a piston rod extending outwardly therefrom, said piston rod having an end pivotally connected to said linkage, said cylinder being actuatable so as to move said piston rod between a retracted position and an extended position, said lifting bar being pivotable relative to the movement of said piston rod between said retracted position and said extended position.
