Patent ID: 7850114

Claim:
A flat sanitary door handle mechanism comprising: a flat handle having two opposite sides with a usable side having an area that is graspable by hand and facing a door, the flat handle having a flat surface, wherein the flat handle is attached to a base plate pivoted on a flange of a mounting bracket; a rotatable fresh sanitary material feed spool and a rotatable take-up spool of different structural diameter to enable the two spools to be distinguishable, wherein both of the two spools are mounted separately on the same base plate as the flat handle, one spool to each opposite side of the flat handle, each having separate parallel axes of rotation, and wherein the two spools are also mounted on the same base plate that is pivoted on the flange of the mounting bracket; a mechanical manually operated material advancing mechanism configured for resupplying the flat handle with fresh sanitary material by pulling a length of the sanitary material from the feed spool each time the flat handle is pulled away from a door surface and released through a displacement angle relative to the mounting bracket, as pivoted on the mounting bracket, by replacing used material in the area of the flat handle that is graspable by hand; and a casing that is fixed to the mounting bracket and encloses the material advancing mechanism and the two material spools configured such that only a usable portion of the flat handle, which includes the usable side with the area that is graspable by hand, is protruded from the casing, wherein the flat handle and the base plate are configured to operate the material advancing mechanism when the flat handle is pulled away from the door surface and released through the displacement angle whereby the flat handle, the two spools, and the base plate are moved through the displacement angle, relative to the fixed casing, by being pivoted on the flange; wherein the sanitary material on the feed spool and the used material on the take-up spool are a continuous length of a flat paper/film that is fed to an outside surface of the usable side with the area that is graspable by hand and the flat paper/film goes around an end of the flat handle that is distal from where the flat handle is pivoted on the flange of the mounting bracket to form a barrier between a hand of a user and the opposite sides of the flat handle; and wherein the flat sanitary door handle mechanism is configured for being attached by the mounting bracket on a pull door either with an axis of rotation of the flat handle parallel with respect to a pivot axis of the door or perpendicular to the pivot axis of the door, depending on the ease of operation desired, with the axis of rotation of the flat handle being parallel to the flat surface of the door to which the mechanism is attached.
