发明名称 Anchor structure
摘要 An anchor structure for exerting a pulling force against a vehicle structural member for straightening operations utilizes a lever arm including a bar member for positioning in an upright relationship and a base member affixed thereto. The bar member has an upper end portion, an intermediate portion and a bottom end portion and is of a rigid material to resist the bending forces applied thereto. The base member is affixed to the bottom end portion and extends laterally therefrom and permits the bar member to rock forwardly and rearwardly on a supportive surface. A lower attachment hook is secured to the lever arm generally at the bottom end portion for connection to a first anchor chain extending away from the lever arm in a direction opposite to a desired direction of pull and prevents movement of the base member outwardly of the first anchor chain. An upper attachment hook is secured to the lever arm at the intermediate portion for connection to a pulling chain extending away from the lever arm in a desired direction of pull whereby a pulling force is exerted on the lever arm to swing the upper end portion toward the pulling chain. The upper end portion is engaged with a vehicle structural member and exerts a pulling force thereon to either anchor a vehicle or to straighten bent vehicle structural members depending upon the extent of pulling force applied.
