Definitions

  • the present disclosure pertains generally to accessories for use in combination with a basketball goal assembly. More particularly, the present invention pertains to devices helpful in damping movement and vibration of a basketball goal assembly.
  • pole mounted basketball goal assemblies are of especial concern because in pole-based arrangements the basketball backboard assembly functions as a weight mounted at the end of a cantilevered lever arm extending from a base, creating a leveraging effect against the base.

  • FIG. 1 illustrates representative basketball goal assembly 1000 with an example embodiment of a tuned mass damper 10.
  • Tuned mass damper 10 is mounted adjacent the upper end 1004 of pole 1002.
  • a tuned mass damper or TMD also known as a harmonic absorber, is typically a relatively small resonant system, including a mass, a spring and a damper or dashpot aspect.
  • a tuned mass damper can be mounted to certain structures to reduce the amplitude and time of the structure's natural vibration frequency as the structure returns to a static state after an external force is applied.
  • the damper is tuned to a frequency so that it resonates out of phase with the structure's motion.
  • Using a tuned mass damper can minimize and/or prevent discomfort, wear and tear, damage, and/or structural failure.
  • a tuned mass damper typically includes a mass (m), a spring with a spring constant (k) and damper aspect (c).
  • a tuned mass damper 10 is added to a basketball goal assembly 1000.
  • External forces in this context include basketball impacts against the basketball backboard, rim or post or forces from a player grabbing and/or hanging on and then releasing the rim or otherwise impacting the basketball goal assembly.
  • a basketball goal assembly includes the mass of the backboard assembly mounted at the upper end of a vertical cantilever beam. Accordingly, the external forces cause the basic basketball goal assembly 1000 to vibrate/resonate for a period of time after an impact until the assembly returns to a normal, static state. It has been found that incorporating a tuned mass damper 10 into a basketball goal assembly can substantially accelerate the damping and efficiently reduce the time it takes for the basketball goal assembly to return to a normal static state.

Accordingly, the subassembly can be selectively arranged in height and adjusted to a desired height relative to flexure 140 within the defined range.
  • Changing the mass height effectively changes the lever arm length of flexures 140, slightly changing the performance of the tuned mass damper. This allows the tuned mass damper 110 to be further tuned or customized.

  • FIG. 10 An illustration of the magnetic flux circuit of tuned mass damper 10 is shown in FIG. 10. Specifically, the N poles of the magnets 52 are forwardly and rearwardly offset on opposing sides of conductor plate 30. When an external force is applied to the basketball goal it causes a movement of the backboard assembly and pole and correspondingly imparts movement to the tuned mass damper 10. This causes the moving mass to begin to oscillate rearward and forward relative to plate 30. The mass is arranged as an inverted pendulum above the pivot point.
  • the movement of the moving mass with magnets 52 creates a flux and eddy currents through conductor plate 30 and ballast blocks 54.
  • the flux moving through the conductor plate 30 creates a drag force, which dissipates energy within the system, damping movement of basketball goal assembly 1000.
  • Magnetic damping provides linear viscous damping. Further, the operation of the magnets and the tuned mass damper efficiency is substantially temperature invariant.
  • Examples of alternate damping mechanisms which can be used in the disclosed embodiments with appropriate modifications include liquid damping arrangements, wherein a fluid is allowed to travel within a defined pathway to absorb energy.
