Abstract: Improvements handle for door closing is disclosed. The handle is rotatable from an outer housing that both protects the handle and provides a structural frame for mounting the handle to a pre-existing door. A typical installation is to place the handle closer to the hinge side of the door. This allows a user to require a shorter reach and pull to the door. Because opening a door for a wheelchair requires the door to almost be completely opened. The handle also has a rotation stop that prevents the handle from being rotated out of the housing more than 90 degrees. A retention and extending mechanism both holds the handle within the housing and slightly opens the handle for a user to grasp. The housing can be surface mount or flush mount. The handle can allow for weight bearing support of a user.
