Abstract
An articulated football goal post can be raised to a high position and a low position relative to the game position, for safety and security, and to facilitate the attachment of television cameras and the like. The crossbar and uprights are supported on the end of a boom pivoted on a vertical column and powered by a hydraulic jack, which may be operated remotely. Through either a parallel linkage or a separate hydraulic jack, the uprights are held in a substantially vertical orientation throughout the pivoting motion.
