Abstract
An improved prying bar includes an elongate shank which has a longitudinal axis, a prying hook at one end and a prying chisel at the other end. The prying hook has a tapered portion extending along a direction generally an angle .alpha. with the longitudinal axis and a generally U-shaped portion integrally formed with the shank and the tapered portion. The tapered and U-shaped portions together form a prying footprint surface facing a direction away from the shank. The angle .alpha. is selected to be greater than 90.degree. and preferably selected within the range of 93.degree.-110.degree.. The prying footprint has a minimum transverse dimension which is substantially greater than the minimum cross sectional dimension of the shank.
Claims19
A prying bar having an elongate shank defining a longitudinal axis and having a prying hook at one axial end and a prying chisel at one end and a prying chisel at the other axial end, said prying hook having a tapered portion extending along a direction defining an angle .alpha. with said longitudinal axis and a generally U-shaped portion integrally formed with said shank and said tapered portion, said U-shaped portion, generally facing a direction away from said shank serving as a fulcrum, said angle .alpha. being greater than 90.degree. and said U-shaped portion having a minimum transverse dimension which is greater than the minimum cross sectional dimension of said shank, whereby said elongate shank is normally offset or spaced from a vertical surface of an object being moved by said prying hook to create a space or clearance between the object's vertical surface and said elongate shank to facilitate the gripping of said shank by a hand of a user.
A prying bar having an elongate shank having a generally oval cross section and defining a longitudinal axis and having a prying hook at one end and a prying chisel at the other end, said prying hook having a tapered portion and a generally U-shaped portion integrally formed with said shank and said tapered portion and generally defining a common plane, said tapered and U-shaped portions forming a prying footprint surface facing a direction away from said shank, said prying footprint surface having a minimum transverse dimension which is substantially greater than the minimum cross sectional dimension of said shank, and said oval cross-section having a major axis generally parallel to said plane and a minor axis generally normal to said plane, whereby the strength of the prying bar in applying forces at said prying hook and said prying chisel can be maximized while the bending of said prying bar shank can be minimized while enhancing the comfort of gripping said prying bar shank by a user.
