<p>A louvre shutter mechanism is disclosed that is adpated to be assembled from kit form. The kit form is adapted so that the shutter dimensions can vary, enabling the shutter to be installed within a window frame that falls within a predetermined range of sizes. The side rails (2) of the shutter incorporate elongate channel portions (3) that are adapted to receive elongate support members (5). The support members (5) include a plurality of apertures (9) that locate pinion gears (6) projecting from the louvres (8). The support members (5) operate to support the louvres (8) as the pinion gears (6) do not engage the side rails (2). The combination of the support rails (5), louvres (8) and pinion gears (6) forms a sub-assembly that can be received with the side rails (2) and top rails (10) of the shutter. The support members (5) include a channel portion (3) that is adapted to receive a gear rack (4). The pinion gears (6) engage the gear rack (4) allowing synchronous rotation of the louvres (8). The pinion gears (6) perform the additional function of operating as spindles for the louvres (8). The use of dual functionality in the pinion gears (6) reduce the complexity of component parts in the kit and assists with ease of assembly.</p> |
