ABSTRACT:
This invention relates to a flat sanitary door handle mechanism incorporating a self-contained mechanical user-operated continuous material advancing system whereby the person touches a fresh length of material while using the flat door handle to open the door thus avoiding hand exposure to the surface of the flat handle which may have been contaminated by previous users. This is achieved by the pull and release of the flat door handle by the user, without any external source of power, the action of which replaces the used length of material with a fresh length and makes the handle ready for use by the next person.
