CONSTITUTION: A multifunctional wind resisting door for a wind lock and a roller comprises a slat wall, multiple rollers(37), and rails. Each roller has a rolling contact unit(372) and a stepped unit(376). The rollers are rolled on the rails. The rails vertically guide the slat wall. Each rail comprises an inward protruded wind lock unit. Each wind lock unit comprises a sliding surface(224a) and a separation preventing surface(224b). The sliding surfaces are in contact with the rolling contact units. The separation preventing surfaces are hung on the stepped units. |
