Patent number: 7338032Abstract: A leverage utilizing bar for facilitating prying a flat member from a slender member. A head extends from a handle. The head engages under the flat member and functions as a fulcrum by engaging the slender member and thereby cause the head to pry the flat member from the slender member when the handle is pushed away from the head by the fulcrum pivoting on the slender member. The head includes a pair of hook members and the handle includes a pair of shank members. The pair of hook members of the head together with the pair of shank members of the handle form a pair of main members, respectively, that are generally J-shaped. The pair of main members diverge from each other as they extend from a common proximal end to distal ends of the pair of hook members of the head so as to allow the head to straddle the slender member.Type: GrantFiled: November 4, 2004Date of Patent: March 4, 2008Inventor: Gerald E.
