发明名称 LIFTING DEVICE
摘要 A device is disclosed that is capable of engaging and holding various materials during lifting and moving thereof. The tool of the present invention comprises two arms or handles that are secured to each other at one end while remaining separate at said end and have heads pivotally secured to the opposite ends thereof for engagement and holding of materials to be picked up. The heads are pivotally secured to the arms in the same plane of the arms and are provided with slots partially along their length through which the arms extend so as to render the tool self-adjusting to the terrain and also height of the individual using same. The heads extend downwardly below the arms, turn inwardly towards each other and are provided with a smooth contour on the inwardly turned ends thereof. Preferably, the heads are constructed from metal having a plurality of openings therein such as expanded metal. The pivot connection between the arms at the end opposite the heads is substantially universal, in that, the individual arms can be moved about various arcs and easily brought back together to a gripping and lifting relationship with the opposing head. The connection is formed by a pivot member which extends horizontally through a first arm, turns outwardly and returns vertically through the second arm.
