Abstract
Opening and closing a door without the use of one's hands is facilitated. For instance, an apparatus can comprise one or two rotatable rings. For a one ring apparatus, the ring can have an opening so that the inner cross section of the opening of the ring can be pushed with a forearm or knee so that the ring will rotate and the person can then pull on the ring with his/her forearm or knee to open the door. In a two-ring apparatus, two adjacent rings, both with openings, can comprise similar push surfaces. When pushed on the pushed surfaces, the rings will rotate and the cross sections of the openings of the rings come into contact with one another, creating a surface against which a forearm or knee can pull on to open the door. A rotation plane converter can turn a doorknob using the apparatus.
