摘要:
A collapsible goal post includes a lower support extending from a playing field; a upper support having a first end and a second end, and a pivot assembly attaching the first end of the upper support to the lower support; an upper assembly comprising two uprights and a crossbar having two ends. The crossbar is attached to the second end of the support at about the midpoint of the crossbar. One of the two uprights is attached to each end of the crossbar. The upper support is configured to pivot about the pivot point assembly to move the upright assembly from a raised position to a lowered position. The two uprights are substantially perpendicular to the playing field in the raised position, and are substantially parallel to and contacting the playing field in the lowered position while the upper assembly and upper support remain attached to the lower support. In another embodiment, the goal post includes a hydraulic cylinder system coupled to the upper support and the lower support to hinder a rate of pivoting of the goal post about the pivot assembly.
