Pivotal and detachable truck body system

A system for detachably securing a truck body onto the bed of a truck as said body is lowered onto said bed, said system comprising:

• guide means secured to the bottom surface of said truck body,
• an adapter frame secured to said bed of said truck, and adapted to receive and guide said guide means as said truck body is lowered onto said truck bed,
• means for locking said truck body onto said adapter frame when said truck body is in its lowermost position,
• means for selectively unlocking said truck body from said adapter frame,
• a hinge member laterally secured across the rear end of said adapter frame,
• a bearing member secured to said truck body and abutting against said hinge member when said truck body is in its lowermost position,
• said bearing member including an elongated semicylindrical abutment surface which abuts against said hinge member, and
• means for securing said bearing member to said hinge member comprising a downwardly extending hook member pivotally secured to said truck body at each axial end of said bearing member, said hook member operatively engaging around said hinge member as said truck body reaches it lowermost position.

A system for detachably securing a truck body onto the bed of the truck as said body is lowered onto said bed, said system comprising:

• guide means secured to the bottom surface of the truck body,
• said truck having a bed and means formed on said bed for receiving and guiding said guide means as said truck body is lowered onto said truck bed,
• means for locking said truck body onto said bed when said truck body is in its lowermost position, and
• means for selectively unlocking said truck body from said bed,
• said means formed on said bed comprising two spaced and parallel longitudinal frame members and two spaced and parallel transfer cross members, each axial end of said cross members extending laterally outwardly from one of said longitudinal frame members and,
• said guide means further comprising a pair of gusset plates operatively associated with each axial end of each cross member wherein each of said gusset plates includes a longitudinal leg which abuts against the outside surface of said longitudinal frame member and a lateral leg which abuts against the outwardly extending axial end of said cross member.

• guide means secured to the bottom surface of said truck body,
• said truck having a bed and means formed on said bed adapted to receive and guide said guide means as said truck body is lowered onto said truck bed,
• means for locking said truck body onto said bed when said truck body is in its lowermost position,
• means for selectively unlocking said truck body from said bed,
• a hinge member laterally secured across the rear end of said bed,
• a bearing member secured to said truck body and adapted to abut against said hinge member when said truck body is in its lowermost position,
• said bearing member including an elongated semi-cylindrical abutment surface which abuts against said hinge member
• means for securing said bearing member to said hinge member comprising a downwardly extending hook member pivotally secured to said truck body at each axial end of said bearing member whereby said hook member operatively engages around said hinge member as said truck body reaches its lowermost position.

A truck body and means for detachably mounting said truck body unto the bed of a truck, said means comprising:

• latch means mounted to said truck body and automatically operable to lock said truck body to the bed of said truck when said truck body is lowered onto the bed of said truck,
• first actuator means mounted to the bed of said truck and operable upon actuation to move said latch means to an unlocked position whereby said truck body can be separated from the bed of said truck,
• a hinge means having a first portion mounted to the bed of said truck and a second portion carried by said truck body, said first and second portions hingedly mating when said truck body is lowered unto the bed of said truck,
• second latch means mounted to said truck body and automatically operable to hingedly lock said first and second members together when said truck body is lowered onto the bed of said truck and
• second actuator means mounted to the bed of said truck and operable upon actuation to move said second latch means to an unlocked position and
• third actuating means mounted to the bed of said truck and engageable with said truck body to, upon actuation, pivot said truck body about said hinge means,
• whereby upon actuation of said first and third actuating means said truck body will be pivoted with respect to the bed of said truck and upon actuation of said first and second actuating means said truck body will be disengaged from the bed of said truck to permit separation of said truck body from said truck.
