Abstract
A block lift for lifting keystone type blocks. The block lift includes a plate having a top surface, a bottom surface and a peripheral edge extending between the top and bottom surfaces. A rod is elongated and has a first end and a second end. The first end is integrally coupled to the top surface of the plate and generally centered in the top surface. The rod extends upwardly from the plate. A handle is attached to the second end of the rod. The plate is positioned through an aperture in a block and turned such that the plate is moved under a bottom surface of the block. The block may then be lifted.
Claims14
A block lifting device for lifting blocks having an aperture extending therethrough, said device comprising:
- a plate having a top surface, a bottom surface and a peripheral edge extending between said top and bottom surfaces;
- a rod being elongated and having a first end and a second end, said first end being integrally coupled to said top surface of said plate and generally centered in said top surface, said rod extending upwardly from said plate;
- a handle being attached to said second end of said rod;
- a rod stabilizer having a top side, a bottom side and a peripheral edge extending between said top and bottom sides, said rod extending through said top and bottom sides of said rod stabilizer such that said rod stabilizer is movable on said rod;
- and
- wherein said plate is positioned through said aperture and turned such that said plate is moved under a bottom surface of said block, wherein said block may be lifted.
A block lifting device for lifting blocks having an aperture extending therethrough, said device comprising:
- a plate having a top surface, a bottom surface and a peripheral edge extending between said top and bottom surfaces, said plate having a generally rectangular shape, said peripheral edge tapering inward from said bottom surface to said top surface, said bottom surface having a length substantially equal to 3½ inches and a width substantially equal to 1½ inches, said peripheral edge having a height generally equal to ¼ inch;
- a rod being elongated and having a first end and a second end, said first end being integrally coupled to said top surface of said plate and generally centered in said top surface, said rod extending upwardly from said plate, said rod having a length generally between 10 inches and 12 inches;
- a pair of protruding members being coupled to and extending outwardly from said rod in generally opposite directions, said protruding members being positioned nearer said first end of said rod than said second end of said rod;
- a rod stabilizer having a top side, a bottom side and a peripheral edge extending between said top and bottom sides, said rod extending through said top and bottom sides of said rod stabilizer such that said rod stabilizer is movable on said rod between said second end of said rod and said protruding members, said rod stabilizer having a length and width substantially equal to the length and width of said bottom surface of said plate;
- a handle being attached to said second end of said rod, said handle comprising;
- a bracket attached to said second end of said rod, said bracket including a tube orientated perpendicular to said rod, said tube having a pair of open ends;
- a pair of elongate members each having a first end and a second end, each of said first ends being extendable into one of the ends of said tube;
- a pair of handgrips, each of said handgrips being attached to one of said second ends of said elongate members, said handgrips comprising a resiliently compressible material;
- wherein said plate is positioned through said aperture and turned such that said plate is moved under a bottom surface of said block, wherein said block may be lifted.
A block lifting device for lifting blocks having an aperture extending therethrough, said device comprising:
- a plate having a top surface, a bottom surface and a peripheral edge extending between said top and bottom surfaces, said peripheral edge tapering inward from said bottom surface to said top surface to facilitate positioning of said peripheral edge below a bottom edge of the block;
- a rod being elongated and having a first end and a second end, said first end being integrally coupled to said top surface of said plate and generally centered in said top surface, said rod extending upwardly from said plate;
- a handle being attached to said second end of said rod;
- and
- wherein said plate is positioned through said aperture and turned such that said plate is moved under a bottom surface of said block, wherein said block may be lifted.
