发明名称 Doorman
摘要 An apparatus for assisting handicapped people in opening doors. The apparatus is used primarily for individuals in wheelchairs, who typically have difficulty in opening doors. The apparatus has a long shaft with two ends, and has a handle attached to one end of the shaft. The other end of the shaft has both a wedge and a pull pin attached to it. The wedge is used to keep an opened door in an open stage by placement underneath the door in between the bottom of the door and a ground surface. The pull pin is used for placement behind a door handle to effectively "pull open" a door.
