PURPOSE: A non-powered automatic door using the weight of a user is provided to prevent environmental contamination because the door is opened and closed without power. CONSTITUTION: A non-powered automatic door using the weight of a user comprises foothold boxes(25,27,29,30,39), a rod(13), a door opening rail(02), a main rail(01), a door hanger assembly(04), a closed wheel assembly(05), and a locking device. The foothold boxes are installed inside and outside an entrance and receive the weight of a user. The rod transfers the weight of the user to a door opening wheel assembly(09). The door opening rail is inclinedly installed on the door opening wheel assembly and the door hanger assembly. The door hanger assembly is connected to the entrance on the main rail and opens and closes a door. The closed wheel assembly closes the door by moving a wheel installed on a door closing rail(03). When the door is not used, the locking device locks the door through key assemblies(44,45). |
