ABSTRACT:
A compound angle limiting device is disclosed herein. The invention provides for control of the angular excursion of a pivotal mass within first and second angles about first and second axes without the necessity for external stops. The invention includes a first coupling mechanism for sensing movement of the mass about the first axis, a second coupling mechanism for sensing movement of the mass about the second axis; a first cam coupled to the mass via the first coupling mechanism and movable in response thereto; and a second cam coupled to the mass via the second coupling mechanism and movable in response thereto. The first and second cams are mounted for physical contact at at least one point to limit the compound angular excursion of the mass via the first and second coupling mechanisms.
