Abstract
A casement operator crank includes a base member, a handle, a hinged detent, and a resilient biasing member. The handle has a main body portion connects to the base member for rotation about a handle axis between an open orientation and a closed orientation. The hinged detent pivotally engages with the base member for rotation about a detent axis between a first orientation relative to the main body portion and a second orientation relative to the main body portion. The resilient biasing member acts between the hinged detent and the handle. The biasing member and hinged detent operably: a) bias the main body portion toward the open orientation about the handle axis when the main body portion is in the open orientation; and b) the main body portion toward the closed orientation about the handle axis when the main body portion is in the closed orientation.
