DOOR SUSPENSION ASSEMBLY

The door suspension assembly comprises a ferromagnetic flat plate (2) horizontally attached to a support rail (1) intended to be attached to a door frame above a doorway or entrance portal. Two supporting blocks (7, 7') are provided having openings, in which cylindrical bearings with an axial hole are located in which a hollow tube (5) is introduced. Said supporting blocks (7, 7') are provided for supporting a door panel (12). Three connectors (3, 4, 6) are located in a fixed position relative to the flat plate (2). Said connectors support small portions of said hollow tube (5), which extends the same length as a required door travel. A magnet array (17) is supported by a plate (14) connected to said supporting blocks (7, 7'), wherein there is a small magnetic gap between the magnet array (17) and the flat plate (2), such that the magnet array (17) generates a magnetic force attracting the plate (2) and lifting thus the supporting blocks (7, 7') which support said door or door panel (12). The door suspension assembly comprises also a primary (15) of a motor attached to said supporting blocks (7, 7') and a secondary located in the interior of the hollow tube (5).
