1. A basketball rim apparatus comprising:
a fixed portion having a mounting plate, wherein said mounting plate includes a cam surface, and said mounting plate adapted to secure to a backboard; a movable portion having a rim and a carrier, wherein said rim and said carrier are pivotable relative to said mounting plate from a rest position to a displaced position out of said rest position; wherein said carrier includes an elongated shaft, a cylinder, a pin, and a tension spring; wherein said elongated shaft includes a first end and a second end; wherein said cylinder includes an inner cylindrical surface and an outer cylindrical surface extending between opposing ends, said inner cylindrical surface having an inner diameter and said outer cylindrical surface having an outer diameter, wherein said inner diameter is smaller than said outer diameter, and a longitudinal axis of said cylinder extends in a direction between said opposing ends; wherein said pin is positioned at said second end of said elongated shaft, and said pin is positioned within said cylinder wherein said cylinder rotates about a longitudinal axis of said pin, and wherein said pin is smaller than said inner diameter of said cylinder to define a clearance therebetween; and wherein said tension spring is connected to said shaft to maintain contact between said outer cylindrical surface of said cylinder against said cam surface and urges said rim and said carrier to return to said rest position from said displaced position, and said longitudinal axis of said pin is out of alignment with said longitudinal axis of said cylinder when said tension spring is maintaining contact between said outer cylindrical surface of said cylinder against said cam surface. |
