Abstract
The pry bar has an ergonomic handle with a convex upper grip surface and a concave lower grip with an inner hard thermoplastic core and an outer elastomeric molded over cover, with the pry bar metal shank having an angularly disposed pry end. The curved upper grip surface portion is more distant from the handle longitudinal axis than the curved lower grip surface portion. The upper grip surface is formed with a distally disposed elastomeric ribbed thumb receiving recess. The handle sides are formed with elongated outwardly bulging palm engaging portions.
Claims26
A pry bar comprising:
- a handle having a distal end, a proximate end and having a grip portion of generally rectilinear cross-section and comprising a convex curved upper grip surface and a concave curved lower grip surface disposed directly below the convex upper grip surface, said handle comprising an inner thermoplastic core and outer integrally bonded elastomeric cover, a shank, said shank having a proximate end and a distal end, said shank proximate end being secured within said handle, said shank being elongate and having a longitudinal axis, said handle distal end being formed with a pry end, said pry end being in angular disposition with respect to said shank longitudinal axis.
A pry bar comprising:
- a handle having a distal end and a proximate end and a grip portion having a generally rectilinear cross-section and comprising an upper grip surface and a lower grip surface disposed directly below the upper grip surface, and a longitudinal axis extending from said distal end to said proximate end, said upper grip surface being convex with respect to said longitudinal axis, and said upper grip surface being further disposed from said handle longitudinal axis than said lower grip surface, and a shank, said shank having a proximate end and a distal end, said proximate end being fixedly secured within said handle, said shank being elongate and having a longitudinal axis, said shank distal end being formed with a pry end, said pry end being angularly disposed with respect to said shank longitudinal axis.
A pry bar comprising:
- a handle having a distal end and a proximate end and a convex upper grip surface and a concave lower grip surface, and a longitudinal axis extending from said distal end to said proximate end, said handle comprising an inner thermoplastic core and outer molded over elastomeric cover;
- and
- a shank, said shank having a proximate end and a distal end, said proximate end being secured within said handle, said shank being elongate and having a longitudinal axis, said shank distal end being formed with a pry end, said pry end being in angular disposition with respect to said shank longitudinal axis, and a metal impact cap disposed at said handle proximate end.
An ergonomic tool handle comprising;
- means for holding a shank;
- a grip portion having a generally rectilinear cross-section and comprising:
- a convex upper grip surface;
- a concave lower grip surface disposed directly below the convex upper grip surface;
- a thumb receiving upper recess;
- and
- a forefinger receiving recessing lower recess;
- wherein the thumb receiving recess is distally disposed from said from upper grip surface and the forefinger receiving recess is distally disposed from said lower grip surface.
The handle of claim 21, said handle having a longitudinal axis, and wherein said upper grip surface is more distant from said axis than said lower grip surface.
