  • Hinged lid for battery compartment in a manually rotatable adjustment knob
    Patent number: 8915392
    Abstract: A rotatable adjustment knob has a knob body mountable to an optical or electronic device for rotation about an axis extending outwardly from the device. The knob body has an opening into a battery compartment sized to receive a battery. A lid is pivotably attached to the knob body for movement between a closed position in which the lid covers the opening, and an open position in which the lid is pivoted away from the opening to provide access to the battery compartment. The lid remains attached to the knob body while in both the open and closed positions for rotation with the knob body about the axis. A resilient seal confronts the knob body and the lid while the lid is in the closed position to thereby seal the opening and the battery compartment. A latch releasably retains the lid in the closed position.
