Title
(EN) IMPROVED LOUVRE MECHANISM
(FR) MECANISME DE STORE VENITIEN AMELIORE
Abstract
(EN)
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.

On décrit un mécanisme de store vénitien conçu pour être assemblé à partir d'un jeu de pièces détachées qui est prévu pour différentes dimensions de lamelles, ce qui permet d'installer ces dernières dans des cadres de fenêtres situés dans une fourchette de dimensions prédéterminées. Les guides latéraux (2) des lamelles comportent des rainures allongées (3) conçues pour recevoir des supports allongés (5) qui présentent plusieurs ouvertures adaptées à des engrenages (6) prolongeant ces lamelles (8). Un support (5) fournit un point d'appui aux lamelles de store (8) quand ces engrenages (6) ne sont pas en prise avec les guides latéraux (2). La combinaison des supports (5), des lamelles (8) et des engrenages (6) forme un sous-ensemble pouvant trouver place dans les guides latéraux (2) et le guide supérieur (10) du store. Les guides latéraux (2) comportent une rainure (3) conçue pour recevoir une crémaillère (4) où les engrenages (6) entrent en prise pour donner une rotation synchrone des lamelles (8). Ces engrenages servent aussi d'axes de lamelles (8) et cette double fonction réduit la complexité du jeu de pièces détachées et facilite le montage de ces dernières.
