Abstract: A basketball goal assembly for mounting on a door frame, door, column or the like in which a support member, such as a backboard, having a hoop secured thereto is height adjustable relative to the floor. The support member, which may be a backboard, includes parallel slots formed adjacent to opposed sides thereof so that it may be frictionally slidably mounted to the door or the like by threading a strap through the slots and attaching the strap ends to the door. U-shaped brackets adapted to engage with opposed edges of a door frame, door or the like may be used to attach the strap ends to the door. A goal including basketball hoop is pivotally secured to the support member or backboard. The installed goal assembly permits friction restrained movement of the hoop to any number of vertical positions along the mounting surface, while frictionally maintaining the hoop in a fixed vertical position during normal use.
