Abstract:
1. An auto-locking adjustment device for an optical device, comprising: an engagement surface fixed relative to the optical device; a spindle rotatably supported on the optical device for rotation about an axis and relative to the optical device and the engagement surface, the spindle operatively coupled to an adjustable portion of the optical device to thereby adjust the adjustable portion in response to rotation of the spindle; a locking mechanism carried by the spindle for rotation therewith, the locking mechanism switchable between a locked condition and an unlocked condition; and a button carried by the spindle for rotation therewith and manually depressible transverse to the axis, the button mechanically driving the locking mechanism such that manually depressing the button switches the locking mechanism from the locked condition, wherein the locking mechanism interlocks with the engagement surface and prevents rotation of both the spindle and the button relative to the optical device, to the unlocked condition, wherein both the spindle and the button are rotatable about the axis relative to the optical device and the engagement surface.
