发明名称 Tool for removing roofing shingles
摘要 A shingle removal tool includes a cutting head attached to a handle, the cutting head having a flat leading portion on which a series of nail engaging slots are formed creating a series of sharp tapered cutting edges at a leading end and a fulcrum edge at a trailing edge. An intermediate portion integrally connects the flat leading portion with the handle. The intermediate portion is curved preferably in the form of an arc of a circle to provide a concave inner surface that imparts a curvature to the lifted shingles and propels them in the direction of advancement of the tool and away from the user. A nail removing opening is provided on the intermediate portion so that larger nails can be removed by lifting the handle which smaller nails can be sheared off by the cutting edges or lifted by the engaging slots by lowering the handle. The tool is ergonomicaly dimensioned to facilitate use by users of average height with confortable and limited movements to increase efficiency of use and to minimize fatigue.
