Abstract

A pry bar sliding fulcrum assembly having a fulcrum and a saddle which slidably mate with a conventional pry bar and which provide a greater force onto a work material than the conventional pry bar alone. The pry bar sliding fulcrum assembly easily and quickly slides away from the work material when a conventional pry bar function is desired and slides toward the work material when an enhanced application force or greater pry bar end displacement is required. The assembly uniquely mates with or is held with the pry bar end whereby the assembly retains a static position relative to the pry bar during use.

Claims5

Dependent claims

A pry bar sliding fulcrum assembly comprising:

an adjustable fulcrum assembly comprising a fulcrum and a saddle;
and
said fulcrum having sides, a front wall, a rear wall, a bar mating wall, and a surface mating wall having a partially arcuate form;
and
said bar mating wall having a shape capable of at least partially mating with an arcuate bend near a broadened end of a pry bar;
and
said saddle having a partially “U” shaped strap with at least two legs, said legs having an interior dimension between said legs substantially equivalent to or slightly larger than a pry bar lever shaft and slidably positionable around the pry bar lever shaft;
and
said fulcrum and saddle having a retainer which pivotally secures said fulcrum with said saddle and allows said fulcrum assembly to slide on the pry bar lever shaft whereby the pry bar may be utilized in a conventional manner while said fulcrum assembly remains attached;
and
said bar mating wall having a gap relative to the pry bar lever shaft, between said retainer and said rear wall, whereby said fulcrum may pivot on said saddle without binding with the pry bar lever shaft whereby said fulcrum assembly may slide from near a pry bar handle towards the broadened end of the pry bar, at least partially mate with the bend, and thereafter allow placement of said surface mating wall onto a work surface and a provision of a greater force and displacement of the broadened end of the pry bar when a force is applied onto the pry bar handle;
and
said fulcrum having a fulcrum cavity with one or more walls and a rotating fulcrum stop within said cavity;
and
said rotating fulcrum stop having a multi-faceted polygonal cross section which allows a selected facet to abut against the pry bar lever shaft or the broadened end of the pry bar;
and
a head or knob attached with said rotating fulcrum stop which allows a rotation of said rotating fulcrum stop external to said fulcrum whereby a desired separation of said fulcrum relative to the pry bar lever shaft or the broadened end of the pry bar is achieved.
