Abstract

La présente invention concerne un illuminateur télescopique présentant une structure simple mais pouvant présenter une configuration ouverte fixe stable en utilisation et pouvant être d'une dimension suffisamment réduite pour être rangée lorsqu'il n'est pas utilisé. L'illuminateur (10) présentant une structure d'ombrelle japonaise est constitué d'un coulisseau (11), d'une pluralité de tendeurs (12) disposés radialement tout en étant symétriques en rotation par rapport à la tige centrale (c) du coulisseau (11), et des nervures (13) disposées respectivement au niveau des tendeurs (12). Autour des extrémités de tous les tendeurs (12), un organe de réglage (14) dont la longueur circonférentielle est inférieure à celle des extrémités de tous les tendeurs (12) lorsque les tendeurs (12) sont perpendiculaires à la tige centrale (c) est mis en tension pour son installation. Une rondelle (15) est prévu pour fixer les tendeurs (12) au coulisseau (11) lorsque les tendeurs (12) sont complètement ouverts.
