ABSTRACT:
An apparatus for lifting a panel to a ceiling has a post having an upper end and a lower end, a spring in the post between the upper and lower ends for at least limited longitudinal compression of the post against a spring force, and a foot pivoted on the lower end about a foot axis transverse to the longitudinal axis. A handle is pivoted on the post between its ends about a handle axis generally parallel to the foot axis and a panel-engaging support bar is pivoted on the upper end of the post about a bar-pivot axis generally parallel to the foot and handle axes, extends perpendicular to this bar-pivot axis, and has one end provided with an outwardly directed cleat. Thus this bar can be engaged under the panel with the cleat against an edge of the panel. At least one bar spring is operatively engaged between the bar and the post for biasing the bar into a position extending perpendicular to the post.
