A method of connecting a locking mechanism in a window member

摘要

A locking mechanism for a window member comprises a gearbox (10) which can be operated to extend or retract a locking bar (18) with a fixing bar (17) overlying the locking bar (18) and being connected to the window member. The fixing bar (17) and the locking bar (18) are connected to the gearbox (10) by connecting the two bars together and, after cutting the bars to size, then attaching the locking bar (18) to a drive member (16) of the gearbox (10) in the extended position. The drive member (16) is then retracted until the ends of the fixing bar (17) and the locking bar (18) are beneath a projecting portion of a face plate (15) of the gearbox (10). The fixing bar (17) is then connected to the window member and the gearbox (10) operated to disconnect the locking bar (18) from the fixing bar (17). <IMAGE>
