BARRIER ARM OPERATOR
A barrier arm operator includes a bracket operably coupled to a drive, wherein the drive rotates the bracket about an axis in a first direction and a second direction opposite the first direction; and an arm coupled to the bracket and driven between a lowered position and a raised position by rotation of the bracket about the axis, wherein the arm is rotatably coupled to the bracket about a pivot axis orthogonally oriented with respect to the axis, wherein the bracket comprises a detent configured to retain the arm in a first position relative to the bracket in an in-use state, and wherein the arm rotates about the pivot axis from the first position to a second position in response to impact of an object against the arm.
