发明名称 Shingle pry bar
摘要 A prying blade (42) having an essentially triangular forward portion (43) is secured to a pipe handle (41) at an angle (D) of between about 20 DEG -25 DEG . The triangular forward portion is formed with a rounded or blunt apex region (47) and the two lateral sides (45a, 45b) have notches (44) therein, leaving teeth therebetween. The notches can engage nails for prying up roofing nails together with roofing shingles. The rear portion of the blade (49) is secured to the handle at a point rearwardly of the apex region, for example by welding, to form with the handle a triangular structure. The prying regions of the blades are thus securely supported. The triangular arrangement permits placement of the apex region of the prying bar between nails and removal by the notches in the sides (45a, 45b), or direct prying by the prying bar of a nail caught at the apex region.
