Abstract
A portal covering such as door or window having a handle that rotates as the door or window rotates. The handle rotatably mounted onto the portal covering and drives the covering around an axis associated with a frame or wall. As the handle is rotated on its axis on the covering, the covering rotates on its axis on the frame. This allows a user to always have contact with the handle at all angles of rotation of the covering. The rotation is accomplished through a direct drive or a gearing system which in this case could be in the form of a miter gear, or other bevel gears linking two shafts together. Other embodiments are also possible such as drive mechanisms associated with a push plate, cables and pulleys, or gear boxes.
