Tilt Lock Mechanism and Method for a Movable Optical or Display Device

Many pilots use head-or helmet-mounted display devices, such as binoculars or night vision goggles, which provide improved vision or heads-up display information. These pilots can experience strong flight vibrations and occasional jolts from hitting large air pockets, or from fierce maneuvering while in battle, which can cause the helmet goggles to be misaligned. This invention offers a mechanism that allows for user's visual adjustment preference of any optical device while maintaining the ability to easliy remove or tilt the device as needed. Specifically, this technology enables users to incrementally rotate the binoculars to tilt, or face more downward or upward, so that the user's line of sight points more downward or more upward. Benefits Positions optical devices to optimize the user's line of sight Enables optical devices to snap into stable adjustable positions Control knobs adjust devices for individuals' interpupillary distance (IPD) Device remains locked into selected position in spite of jolts, jerks and vibrations
