l shaped or right angular hoop mount 30 having a rectangular vertically oriented leg 32 whose side edge margins 34 are slidably receivable within the track channels 24 the leg 32 includes vertically aligned openings that receive the threaded shanks of a pair of carriage bolts which project through the vertical slot 16 the heads 36 of the bolts are vertically slidable in the fastener space 18 during adjustment of the vertical height of the hoop mount fixing of the leg 20 in any vertically adjusted position is achieved by tightening nuts 38 onto the carriage bolts with this arrangement an infinite number of vertical positions may be established along the length of the track opening 26 simply by loosening and retightening the nuts 38 the hoop mount 30 also includes a horizontal leg 40 integral with and forming a horizontal continuation of the vertical leg 32 the legs 32 and 40 are preferably the same width for reasons which will become apparent a usual basketball hoop 42 is welded or otherwise secured to an arcuate outer or free edge of the horizontal leg 40 a pair of diagonally oriented support rods 44 are welded at their outer extremities to opposite sides of the hoop 42 at their inner extremities the rods are welded to the lower portion of the vertical leg 32 as seen in fig1 and 2 the support rods undergo compression to transfer ball impact loads on the top of the hoop 42 to the vertical leg 32 conversely the rods are placed in tension to transfer ball impact loads on the bottom of the hoop the orientation and configuration of the horizontal leg 40 assists in efficiently transferring hoop loads.
