Claims
- 1. Apparatus for mounting, demounting or tilting a container relative to the flat bed of a vehicle through the use of an L-shaped lever having a normally vertical arm pivotally and detachably engageable at its upper end to the front end of said container, and a normally horizontal arm positioned beneath said container and parallel to and above said flat bed, wherein the improvement comprises a pair of transverse, longitudinally spaced-apart pivots, means detachably securing said pivots to said bed, a pair of transversely spaced brackets connected at one end to the rearward of said pivots and at the other end pivotally connected to the rearward end of said horizontal arm, a thrust rod connected at one end to the forward of said pivots and at its other end pivotally connected to the junction of the vertical and horizontal arms of said lever, whereby when said pivots are attached to said bed, that portion of the bed interconnecting the spaced pivots, said thrust arm, said brackets and the horizontal arm of said lever form a rigid four bar linkage defining the path of movement of the upper end of the vertical arm of said L-shaped lever and hence the movement of the front end of said container, and a piston-cylinder assembly for moving said four bar linkage to mount and demount said container, said piston-cylinder assembly being pivotally connected at one end to said bed at a point forward of said spaced pivots, and at its other end pivotally connected to said brackets at a point intermediate their ends.
- 2. Apparatus according to claim 1, in combination with a plurality of rollers attached to the rear end of the bed of said vehicle and supporting the rear end of said container.
- 3. Apparatus according to claim 1, in which said normally horizontal arm comprises one member rigidly connected to said vertical arm and a second member normally extending from and slidably engaging said first member, and in which said brackets are pivotally attached to said slidable member, and a second piston-cylinder assembly connected to said thrust rod for moving said one member into nesting relationship with said second member.
- 4. Apparatus according to claim 2, in combination with a second pair of laterally-spaced brackets pivotally attached at one end to the bed of said vehicle about the axis of said rollers, and in which said detachable means is mounted on said second pair of brackets for alternatively locking said second pair of brackets to the bed of said vehicle or to said container, and in which the spaced-apart pivot attached to one end of the thrust rod is supported by said second pair of brackets and the spaced-apart pivot of the first pair of brackets is held against said bed by said second pair of brackets when they are locked thereto.
- 5. Apparatus according to claim 4, in combination with second detachable means locking the other end of said second pair of brackets to said horizontal arm, during the normal and tilting positions of said container, and unlocking said second pair of brackets from said horizontal arm during the mounting and demounting positions of said container.
- 6. Apparatus according to claim 5, in combination with third detachable means for clamping said horizontal arm to the container during tilting movement of said container, whereby upon actuation of the first piston assembly said L-shaped lever and said second pair of spaced brackets move as a unit with said container during the tilting movement.
