发明名称 PANEL LIFT APPARATUS
摘要 An apparatus illustrated in two embodiments assists a sole worker in the positioning and installing of ceiling panels, such as sheetrock, to ceiling joists. In the first embodiment, a panel is placed on an arm pivotably connected to a post firmly positioned between a floor and a ceiling. Upon the release of a lever, a pressurized gas cylinder causes the arm to lift the panel angularly into substantially horizontal orientation adjacent the ceiling joists. In the second embodiment a plate formed with a ramp portion extends at an angle to a bearing plate portion. The bearing plate portion is fastened to a ceiling joist with the ramp portion angled downward. A first edge of a ceiling panel is placed on the ramp and the oppositeedge of the ceiling panel is lifted by a worker so that the first edge is forcedupward on the ramp to rest on the bearing portion as the second edge is brought into a substantially horizontal position.
