Multi-directional break-away goal
A basketball rim mounting assembly permitting multi-directional deflection in response to extraordinary forces imposed on the rim has a fixed portion coupled to a back board and a movable portion fixed to a basketball rim. The fixed portion can include a back plate secured to a front face of the back board, a pair of bracket plates fixed to extend forward from the back plate, and a base plate fixed between the bracket plates. The movable portion can include a top plate overlying the base plate and a pair of side plates extending downward from the top plate outside the bracket plates. A pair of downwardly extending members are fixed to the top plate in spaced relation to each other. Tilt regulating structure is coupled between the pair of downwardly extending members and to the fixed portion for controlling the extent of deflection of the rim relative to the backboard such that the extraordinary force necessary to cause the rim to break-away from its normal position is the same in any direction.
