Kind Code:
A1
Abstract:
The present invention relates to a multi-point lock system for a fire door. The multi-point lock system for a fire door: has an improved structure which enables a main lock to be assembled by an engagement structure of an internal gear and a pinion module, so as to drastically reduce the assembly process by a non-bolting coupling and simplify the structure of each component, thereby reducing the manufacturing cost; and comprises, as main elements, a body case (10), a pinion module (20), a main lock (30), an upward and a downward rack module (40), (40') and an upward and a downward multi-lock (50), (50') wherein the body case is installed to be switchable by 180 degrees in the front/rear or the upward/downward direction to be universally applicable to a left/right side open-type fire door in a manner of switching the withdrawal direction of the main lock by 180 degrees.
