Abstract:
1. A door suspension assembly comprising: a substantially flat plate formed of ferromagnetic material extending generally horizontally and adapted to be attached to a door frame above a doorway; a guide means having an opening formed therethrough and adapted to support a door panel; a rail extending through said opening and extending at least approximately a length of a required door travel; at least two connectors attached to said flat plate and extending downwardly supporting said rail and said guide means; and a magnet means attached to said guide means and spaced from said plate to form a small magnetic gap, such that said magnet means generates a magnetic force lifting said guide means toward said plate whereby when a door panel is suspended from said guide means, said magnet means generates a magnetic force sufficient to support at least most of a weight of the door panel.
