Claims
exact text as granted — not AI-modified1 . An elevator safety lifting support for an elevator of a drilling rig comprising:
a base; a stand emanating perpendicularly from the base and having an outside diameter smaller than an inside diameter of the elevator; and a handle.
2 . The elevator safety lifting support of claim 1 in which the stand is cylindrical in shape.
3 . The elevator safety lifting support of claim 1 in which the handle is shaped for attachment to a hook of a winch line.
4 . The elevator safety lifting support of claim 1 in which the stand further comprises:
an arm and a sleeve; the arm having a rectangular shape in a lateral cross-section, a top, sides, and a bottom, the bottom having extensions extending outwardly from the bottom perpendicularly to the sides; the sleeve having a cylindrical shape, a top, a bottom, and sides and forming a bore, the bore having an inside diameter greater than a distance between the sides of the arm for a snug fit when the sleeve is fitted over the arm; and the arm and the sleeve being attached to the base.
5 . The elevator safety lifting support of claim 4 in which the top of the arm extends beyond the top of the sleeve when the sleeve is fitted over the arm.
6 . The elevator safety lifting support of claim 4 in which the handle is a lifting eye cut into the arm.
7 . The elevator safety lifting support of claim 4 in which the base comprises a hole having a shape corresponding to the rectangular shape of the arm.
8 . The elevator safety lifting support of claim 7 in which the arm is inserted through the hole of the base until the extensions of the arm prevent the arm from being inserted any further and the sleeve is fitted over the arm after the arm has been inserted through the hole of the base.
9 . The elevator safety lifting support of claim 1 used for supporting an elevator off a floor of a drilling rig.
10 . The elevator safety lifting support of claim 1 used for lifting an elevator off a floor of a drilling rig.
11 . The elevator safety lifting support of claim 1 used for lowering an elevator to a floor of a drilling rig.Join the waitlist — get patent alerts
