ABSTRACT:
A lens support system (10) for rigidly securing a lens (12, 12') to a bridge mounting member (14) or an end piece member (14'). The lens (12, 12') includes a longitudinally extended slot (28) passing through the lens (12, 12') in a vertical direction (18) and defining longitudinally displaced end sections (30 and 32). The lens support system (10) includes a pair of vertically extending post members (50 and 52) which are mounted on an annular disk member (34) having a central opening (44). The post members (50 and 52) extend through the slot (28) and the post members (50, 52) matingly engage the end sections (30, 32) of the slot (28). The longitudinally displaced post members (50 and 52) prevent rotation of the lens (12, 12') about a vertical axis. A threaded member (60) extends through the central opening (44) of the disk member (40) and is compressively engaged with upper surfaces of the posts (50 and 52) by threaded securement of a nut member (66) threadedly engaging a lower portion of the threaded member (60). In this manner, the lens (12, 12') is rigidly secured to frame mounting member (14) in both compressive force loading, as well as providing a means whereby lens (12) is rotationally constrained with respect to the frame mounting member (14) about a vertical axis.
