Abstract
An articulated flag body member permitting bi-directional passage of an object. The articulated flag body member has a flag body pivotably connected to a flag foot. As rotation of the flag foot occurs in one direction, the flag body rotates by engagement of a recess of the flag foot with a stop member extending along a projecting leg of the flag body. As the flag body rotates, a notch at the upper portion of the flag body changes positions such that light, or other signals, may no longer pass through the notch. Thus, positional indication of an object detected by rotation of the flag body. As rotation of the flag foot occurs in an opposite direction, an object may be extricated or removed.
