Abstract
An adjustment mechanism for adjusting headgear-mounted vision equipment with respect to the viewer's eyes. A goggle (14) is mounted to a carriage (20) which is slideable on a frame (10) mounted to the headgear (12). The carriage (20) is slideable on a rail (16) by a tongue and groove arrangement (48), and slideable on a rod (42). The carriage (20) includes a cavity (62) with a coil spring (64) therein encircling the rod (42). In its relaxed state, the coil spring (64) firmly engages the rod (42) and prevents movement of the carriage (20) on the rod (42). The coil spring ends (66, 68) are compressible together to release the engagement of the coil spring (64) about the rod (42). A finger-operated plunger assembly (28) includes a slotted end (118) for engaging one spring end (68). When the plunger button (116) is depressed, the spring ends (66, 68) are pressed together, thereby permitting adjustment of the carriage (20) on the rod (42).
