## Abstract

A pry bar with a sliding fulcrum assembly wherein the sliding fulcrum has a body with a passage therethrough that is configured and contoured for the fulcrum body to normally freely slide along the elongated pry bar, when hanging on the pry bar. The bottom of the passage through the fulcrum body is provided with a bar friction engagement surface on a bottom portion of the passage whereby the fulcrum is non-slidably engaged with the pry bar when the bottom of the fulcrum body is engaged with the floor surface under applied lifting force of the lifting lip of the pry bar applied against an object to be lifted.

## Claims

### Claim 1

In combination, a pry bar with a sliding fulcrum assembly, the combination comprising:
said pry bar having a generally horizontally extending lifting arm with a lifting lip at the distal end of said lifting arm for engaging an object to be lifted, and an upright elongated handle coupled to the proximal end of the lifting arm through a curvature provided between said handle and said lifting lip;
said sliding fulcrum assembly having a body with a passage therethrough configured and contoured for said body to normally freely slide along said bar, including said curvature, when hanging on said bar, said body having a bottom contact surface for engaging a floor surface as a fulcrum;
the bottom of said passage having a bar friction engagement surface on a bottom portion thereof whereby said body is non-slidably engaged with said pry bar when said bottom contact surface is engaged with a floor surface under applied lifting force of said lifting lip against an object to be lifted.

### Claim 2 (depends on 1)

The combination of claim 1, said friction engagement surface including a wedge shaped configuration whereby said surface frictionally engages said bar with a wedging action.

### Claim 3 (depends on 1)

The combination of claim 1, wherein said pry bar and said passage having corresponding non-round cross sectional configurations whereby said body is prevented from rotating on said bar.
