Abstract

A magnetic lifting apparatus includes a plurality of magnetic substances, a plurality of rotor seat members, magnetic rotors, and permanent magnets alternately aligned with the plurality of magnetic substances. The apparatus includes stopping members for stopping rotation of magnetic rotors in a one way direction whereby upon lifting the operating member, the magnetic lifting apparatus either has a magnetic activity or no magnetic activity so as to attach to or release from an object, respectively.

Claims10

Dependent claims

A magnetic lifting apparatus comprising:

a housing defining a pair of side walls, a top cover, a bottom plate, and a pair of front and rear walls;
an operating member disposed in an opening of a center portion of said top cover, said operating member including a link and a pair of upper and lower edges for stopping the operating member at stopping portions extended from the circumference of said opening;
a tubular body member disposed within a hollow region of said opening, said tubular body including a ring gear surrounded on the central outer surface thereof, a first axle having a pair of convex ends extended from both ends thereof, and a circular plate, said axle having a cam configured member mounted thereon for stopping movement of said axle;
a rack gear connected to said operating member and disposed within said opening, said rack gear being in a gearing relationship with the ring gear to rotate the ring gear of the tubular body member during movement of said operating member;
a plurality of rotor seat members disposed within said housing, each rotor seat member including a magnetic rotor having a non-magnetic center zone, an angular axial aperture disposed at the center thereof, and a pair of permanent magnets;
a plurality of magnetic substances alternately aligned with said plurality of rotor seat members and disposed within said housing, each magnetic substance including a non-magnetic center zone and an angular axial aperture for matching with said angular aperture of the rotor seat member and disposed at the center thereof;
a pair of second and third axles passing through said angular axial apertures and connected to said pair of convex ends of the connecting axle by concave ends disposed ends thereof;
and
means for locking said magnetic apparatus in one of an activated or deactivated position, said means for locking connected to one of said pair of axles and said connecting axle for stopping a stopper in a one way direction, whereby upon lifting the operating member, since the rack gear goes up for rotating the ring gear in the clockwise direction and the magnetic rotor rotates so as to match the rotor with the permanent magnets in same plurality, the magnet lifting apparatus is in an on-position to attach to an object to be lifted or moved, and after lifting or moving, upon lifting the operating member, sine the magnetic rotor is unmatched with the permanent magnets in an opposing polarity, the magnetic lifting apparatus is in an off-position to release from the object.
