Title (EN) LENS MOUNTING
(FR) MONTURE DE LENTILLE
Abstract: front page image
(EN)A lens mounting for enabling rapid changes of lenses wherein a lens carrying structure (48) is arranged to be detachably secured to an apertured support structure (25, 30) by virtue of lugs (50) provided on the lens carrying structure (48) engaging between a planar, annular, spring element (32) and a rigid portion or portions (54) of the support structure (25, 30). Owing to the resilience of at least a portion (56) of the spring element (32), the latter biases the lugs (50) against said rigid portions (54), thereby securing the two structures together. In the preferred embodiment, the rigid portions (54) are inwardly extending lugs of a mounting plate (30) engaging with outwardly extending lugs (50) of the lens carrying structure (48). In another embodiment, the spring element (32) and mounting plate (30) are secured to the lens carrying structure (48) and the outwardly extending lugs are provided on the support structure (25).
(FR)Dans une monture de lentille permettant des changements rapides de lentille, une structure portante de lentille (48) est disposee pour etre fixee de maniere detachable sur une structure de support ajouree (25, 30) au moyen d"oreilles (50) prevue sur la structure portante de lentille (48) s"engageant entre un element ressort annulaire, en plan (32) et une ou des portions rigides (54) de la structure de support (25, 30). A cause de l"elasticite d"au moins une partie (56) de l"element ressort (32), ce dernier pousse les oreilles (50) contre lesdites parties rigides (54), fixant ainsi les deux structures ensemble. Dans le mode de realisation prefere, les parties rigides (54) sont des oreilles s"etendant vers l"interieur d"une plaque de monture (30) cooperant avec des oreilles qui s"etendent vers l"exterieur (50) de la structure portante de lentille (48). Dans un autre mode de realisation, l"element ressort (32) et la plaque de monture (30) sont fixes sur la structure portante de lentille (48) et les oreilles s"etendant vers l"exterieur sont prevues sur la structure de support (25).
