Device for loading and unloading a load relative to a bed of a truck

A loading device for loading and unloading a load relative to a horizontally disposed bed of a truck, said device comprising:

• a gliding arrangement secured to a first end of the load, said gliding arrangement engaging a rear end of the bed of the truck when the truck is reversed towards the gliding arrangement;
• a leg secured to a second end of the load such that the load is disposed substantially between said gliding arrangement and said leg;
• a lifting mechanism secured to said leg for selectively lifting and lowering said leg;
• a support pivotally secured to the load between said gliding arrangement and said leg, the arrangement being such that in a first disposition of the device, when said lifting mechanism is adjusted to a lifted mode so that said leg is lifted such that the second end of the load is disposed higher than the first end of the load, the truck is reversed towards said gliding arrangement such that said gliding arrangement engages the rear end of the bed of the truck and such that in a second disposition of the device, when the truck is further reversed towards the second end of the load, said support pivots towards the load due to contact of said support with the truck and such that in a third disposition of the device, when the truck has been yet further reversed so that the load is disposed above the bed of the truck, said lifting mechanism is adjusted to a lowered mode such that the second end of the load is supported on the bed of the truck;
• and
• said lifting mechanism including:
• a jack.

• said gliding arrangement including:
• a roller rotatably connected to said first end of the load;
• shaft having a first and a second extremity, said extremities of said shaft being bearingly supported by the first end of the load;
• said roller being rotatably supported by said shaft;
• said leg including:
• a transverse member having a first and a second termination, said transverse member being rigidly secured to the second end of the load;
• a first strut having a first and a second extremity, said first extremity of said first strut being connected to said first termination of said transverse member;
• a second strut having a first and a second end, said first end of said second strut being connected to said second termination of said transverse member;
• said first strut including:
• a first portion secured to said first termination of said transverse member;
• a second portion slidably connected to said first portion;
• a locking mechanism for locking said portions together such that adjustment of a distance between said first and second extremities of said first strut is permitted;
• said second strut including:
• first arm secured to said second termination of said transverse member;
• second arm slidably connected to said first arm;
• a fastening mechanism for fastening said arms together such that adjustment of a space between said first and second ends of said second strut is permitted;
• said first extremity of said first strut being rotatably secured to said first termination of said transverse member;
• said first end of said second strut being rotatably secured to said second termination of said transverse member;
• an anchor for selectively anchoring said first strut in an operative disposition thereof and an inoperative disposition thereof;
• a further anchor for selectively anchoring said second strut in an operative disposition thereof and an inoperative disposition thereof;
• said lifting mechanism including:
• a first jack rotatably secured to said second portion;
• a pin for selectively locking said first jack in an operative disposition thereof and for locking said first jack in an inoperative disposition thereof;
• a second jack rotatably secured to said second arm;
• a further pin for selectively locking said second jack in an operative disposition thereof and for locking said second jack in an inoperative disposition thereof;
• said support including:
• a first brace pivotally connected to a first side of the load;
• a second brace pivotally connected to a second side of the load;
• said first brace including:
• a first member having a first and a second end, said first end being pivotally connected to the first side of the load;
• a second member having a first and a second extremity, said first extremity of said second member slidably cooperating with said second end of said first member;
• a lock for adjustably locking said first member relative to said second member;
• a further lock for locking said first end of said first member relative to the load when the load is to be supported in an absence of the truck;
• said second brace including:
• a third member having a first and a second end, said first end being pivotally connected to the second side of the load;
• a fourth member having a first and a second extremity, said first extremity of said fourth member slidably cooperating with said second end of said third member;
• a locking device for adjustably locking said third member relative to said fourth member;
• a further locking device for locking said first end of said third member relative to the load when the load is to be supported in the absence of the truck;
• and
• said first and second brace pivoting between a stowed disposition and a supporting disposition thereof by gravity.
