摘要： A pre-mounted fold-up basketball backboard and goal structure includes a molded fiber glass backboard with a network of reinforcing ribs on the rear surface of the backboard to strengthen the backboard and eliminate dead spots. The goal structure includes a hoop or rim with a support frame fixedly connected to the hoop and hinged to a base plate assembly which is secured to the backboard. The hinged connection of the hoop with the base plate assembly enables the hoop to be folded parallel to the backboard for shipment of the assembled hoop and backboard in a thin container. When erected for use, reinforcing rods extending from the hoop are secured to the base plate assembly by a clamping plate.
