ABSTRACT:
A mesh net supporting framework for a hockey goal which is readily collapsed for transportation or storage has elongated tubular members hinged together at their respective ends and locking mechanisms at those hinges for securing the tubular members in mutually perpendicular configurations. The locking mechanisms may comprise an elbow with one of the tubular members and a short tube extending therefrom perpendicular to one another. There is an abutment on the short tube, and a cylindrical cuff surrounds the other of the tubular members, with that cuff having a semicylindrical extension for engaging the abutment. The other tubular member also has a semicylindrical end portion for engaging the abutment. Relative angular movement of the tubular members is precluded when the semicylindrical end and the semicylindrical extension are misaligned, while the tubular members are relatively angularly movable when the semicylindrical end and the semicylindrical extension are positioned adjacent the same semicircular portion of the abutment. The locking mechanisms are freed to collapse the goal by rotating the cuff through about one hundred eighty degrees about the other tubular member.
