Apparatus for grasping, lifting and moving a large panel

摘要

A panel gripping and lifting device (100) having a clamping assembly (105) having a handle assembly (162) rotatably interrelated with a spaced apart opposing jaw assembly (107) by a cam assembly (149). Jaws of the opposing jaw assembly (107) have a planar jaw inner surface (116); when the spacing between the jaws is increased, the planar jaws are fitted on either side of a panel; when the spacing between the jaws is lessened the planar jaws contact surfaces of the panel exerting a gripping force against the panel. When gripping forces are exerted against the panel the handle assembly (162) enables the lifting and moving of the panel such as seated multipane window (220) window frame (200) having an outwardly extending nail fin (210) or a sheet metal panel.;An alternative embodiment has opposing jaws rotating in the same plane and separated by jaw spacing. A first jaw and a second jaw are positioned on either side of a frame channel and, when the embodiment is rotated the jaw spacing is lessened causing the first jaw and the second jaw to clamp against the frame channel thereby allowing lifting of large framed units such as glass door units.

1. A panel gripping and lifting device (100) comprising
a clamping assembly (105) having a handle assembly (162) rotatably interrelated with a spaced apart opposing jaw assembly (107) by a cam assembly (149); and jaws of the opposing jaw assembly (107) have a planar jaw inner surface (116); when the spacing between the jaws is increased, the planar jaws are fitted on either side of a panel; when the spacing between the jaws is lessened the planar jaws contact surfaces of the panel exerting a gripping force against the panel; and when gripping forces are exerted against the panel the handle assembly (162) enables the lifting and moving of the panel by compression and relaxation of the said jaw assembly (107); and the jaw assembly (107) comprises a planar first jaw (110) in parallel with a planar second jaw (120); said first jaw (110) and said second jaw (120) are spaced apart by a jaw spacing (125) and are moveably interconnected by at least one rigid jaw interconnection stabilizer (130); and, an elastic jaw spacer (140) is placed, in the jaw spacing (125), between said first jaw (110) and said second jaw (120) at or proximal to the jaw top edge (113); and, the spacing of the spaced apart opposing jaw assembly (107) is lessened and increased by a cam function of the cam assembly (149), activated by the rotation of the handle assembly (162), by compression and relaxation of the said jaw spacer (140).
