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.
- Traditional pole mounted systems have correspondingly had to balance a longer natural damping time before the system returns to a static state versus using heavy materials and a secure or heavy base to minimize the goal's natural damping time. Arrangements to accelerate damping and to minimize the damping time for basketball goal assemblies are desired.
- Certain disclosed embodiments include a basketball goal assembly including a basketball backboard and rim assembly and a tuned mass damper operatively mounted to the backboard and rim assembly to dampen vibration of the assembly.
- the tuned mass damper is mounted to a pole having an upper end and a base end, where the pole supports the backboard and rim assembly above a support surface.
- the tuned mass damper is mounted adjacent the upper end of the pole.
- a basketball goal assembly include a basketball backboard and rim assembly and a tuned mass damper operatively mounted to said backboard and rim assembly to dampen vibration of the assembly.
- An example embodiment of the tuned mass damper includes a conductor plate arranged normal to the plane of the basketball backboard, a pair of flexures arranged on opposing sides of the conductor plate, and a moving mass extending over the conductor plate and mounted to the pair of flexures.
- the moving mass may comprise a pair of magnets arranged on opposing sides of the conductor plate, with the magnets laterally offset from each other.
- the pair of flexures may be leaf springs.
- the moving mass may be formed as a pair of symmetric
- each subassembly includes a magnet block and a ballast block.

- the tuned mass damper uses magnetic damping.
- the basketball backboard defines a planar backboard surface and the tuned mass damper is mounted to be operative along a plane normal to the backboard surface.
- the tuned mass damper comprises a moving mass arranged on a pair of flexures, such as but not limited to leaf springs arranged on opposing sides of a conductor plate.
- the moving mass may include at least one magnet arranged in the moving mass.
- the moving mass optionally may include a pair of magnets arranged on opposing sides of a conductor plate.
- Certain embodiments incorporate methods for arranging and using a tuned mass damper on a basketball goal assembly to dampen impact forces applied to the basketball goal assembly, thereby minimizing the time to return the basketball goal assembly to a static state.

- a damping apparatus such as a tuned mass damper or "TMD” operatively attached or for attachment to a basketball goal assembly.
- Embodiments of the disclosure will be described in detail with reference to a representative basketball goal assembly 1000 illustrated in FIG. 1. Specifically, various aspects of the disclosed embodiments will be discussed with reference to a basketball goal assembly 1000 having a support such as a pole or post 1002 with a top end 1004 and a bottom end 1006.
- a backboard assembly having a backboard 1010 and a rim assembly 1012 attached thereto is coupled to the top end 1004 of the pole or post 1002.
- the height of the backboard 1010 and rim assembly 1012 may be adjustable relative to the pole 1002.
- the post 1002 is often perpendicular to the support surface supporting the basketball goal assembly 1000. For example, some basketball goal assemblies have the post 1002 entering a hole in the ground or being bolted to a base in or on the ground.
- basketball goal assemblies have the post 1002 being supported by a weighted base, such as a sand or water filled container.
- a weighted base such as a sand or water filled container.
- the bases are portable and may have wheels attached thereto.
- Example backboard sizes may be 54", 60" or 72" and they may be adjustable in height to place the hoop as desired, for example within a range between 7.5' and 10' above the playing surface.
- Embodiments of the present disclosure also include basketball goal assemblies with slanted, segmented and/or curvilinear posts and basketball goal assemblies that are not mounted on a post.
- some basketball goal assemblies are mounted on a wall and/or are suspended from a ceiling.
- different arrangements of basketball goal assemblies are contemplated by the inventor(s) of the present disclosure and the embodiments illustrated and described in the present disclosure may be modified for the various arrangements of basketball goal assemblies.
- 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.
- FIGS. 3-6 An example tuned mass damper 10 usable with a basketball goal assembly is illustrated in detail in FIGS. 3-6.
- a TMD base or mounting block 20 can be used to mount the tuned mass damper 10 to the basketball goal assembly.
- the tuned mass damper 10 can be mounted directly to the backboard and rim assembly.
- the tuned mass damper 10 can be mounted adjacent an upper and of a supporting pole or post 1002.
- the tuned mass damper, and specifically the moving mass (m) has a total mass of approximately ten pounds. In comparison, the mass ratio may be calculated considering an example basketball goal assembly of 225 pounds or more.
- Conductor plate 30 Extending upward from a base or mounting block 20 is a conductor plate 30.
- Conductor plate 30 is preferably formed of a magnetic conductor material such as copper or aluminum.
- plate 30 is a separate upper portion mounted via fasteners to a lower plate portion 34.
- plate 30 and lower plate portion 34 may be an integral, single piece.
- plate 30 may be secured within the system, typically in a fixed position, without directly extending from mounting block 20.
- the plane of plate 30 is normal to the plane of backboard 1010.
- An example plate thickness is within a range of approximately 0.1 - 0.3 inches, with a preferred thickness of approximately 0.2 inches.
- Flexures 40 are formed as flexible metal plates, but alternate flexure materials or structures can be used. Flexures 40 are arranged on opposing sides of plate 30 and are arranged to move or bend parallel to plate 30. Lower ends 42 of flexures 40 are secured to mounting block 20, for example with
- the movable mass (m) as illustrated includes magnet blocks 50, magnets 52, ballast blocks 54, and top plate 60, as well as fasteners.
- the moving mass (m) forms an inverted pendulum and is arranged to extend over the top and across plate 30 and then downward with portions facing opposing faces of plate 30.
- a gap G is defined within the moving mass parallel to plate 30. Plate 30 is located within the gap, without touching the moving mass.
- An example gap spacing is approximately 0.03 inches from either side of plate 30.
- the moving mass is arranged on flexures 40 to be allowed to move forward or rearward relative to plate 30 as the flexures 40 bend. Flexures 40 define a pivot axis adjacent lower ends 42. Flexures 40 are typically perpendicular to plate 30, and aligned with the center of plate 30.
- the movement of the moving mass is within the limits defined by the radial length and degree of bending in flexures 40.
- Plate 30 may have an arcuately curved upper edge 32 to accommodate the radial movement of the moving mass (m).
- the moving mass is arranged with a single degree of freedom normal to the backboard. The moving mass couples the flexures 40 together so that they are synchronized in their movement.
- bumper pads 65 can be arranged on plate 30. Bumper pads 65 limit the forward and rearward movement of the moving mass and correspondingly the flexures 40. In the illustrated embodiment, pairs of bumper pads 65 are arranged on opposing sides of plate 30 adjacent the upper forward and upper rearward edges of plate 30. As illustrated, each pair of bumper pads includes one bumper pad with a protruding threaded shaft or bolt which extends through plate 30 and is received in a mated threaded fastener or nut in a corresponding bumper pad. Bumper pads 65 can be mounted in alternate ways, such as using different fasteners, clamps, adhesive, material fusion, or welding, to name a few examples. Bumper pads 65 can be formed of rubber, plastic or another material.
- Moving mass (m) includes a set of magnet blocks 50 and ballast blocks 54 arranged at the upper ends 44 of flexures 40.
- the blocks are arranged in an alternating pattern, with a ballast block arranged opposing a magnet block on opposing sides of plate 30, and also with a ballast block arranged opposing a magnet block on opposing side of each flexure 40.
- the magnet blocks 50 and ballast blocks 54 form symmetric subassemblies (s) on opposing sides of plate 30, with each subassembly (s) clamped to a respective flexure 40.
- the ballast blocks 54 are made of a material which has high magnetic permeability such as 1010 steel.
- the magnet blocks 50 are also made from 1010 steel.
- the magnet blocks 50 are made from a material which has relatively low magnetic permeability such as stainless steel.
- Magnet blocks 50 may each include an integrated or separate magnet housing.
- Top plate 60 couples the subassemblies (s) together.
- Top plate 60 may be made from a non-magnetic material such as aluminum. The materials preferably are chosen to maximize containment of the magnetic flux within the circuit.
- top plate 60 can be chosen or changed to select a desired mass and therefore to tune the performance of the tuned mass damper.
- At least one and more preferably a pair of magnets 52 are arranged within the moving mass (m). Specifically, a magnet 52 is arranged in each magnet block 50, and the magnets are offset from each other on opposing sides of plate 30. A face 53 of each magnet is arranged parallel to and facing a corresponding face 33 of plate 30 and is aligned with an opposing ballast block 54.
- the magnetic poles are arranged perpendicular to plate 30. The magnetic poles are arranged to match, for example with the respective north poles of magnets 52 facing plate 30.
- An example magnet size is 0.75" in diameter by 0.5" long.
- Example magnets are neodymium iron boron magnets.
- magnets can be mounted to a center plate or separately from the mass, and the moving mass dampens vibration by movement relative to the magnets.
- the tuned mass damper 10 is mounted adjacent an upper end 1004 of a support pole 1002.
- the tuned mass damper 10 can be mounted internally to the pole, optionally with portions protruding upward from the pole, as illustrated in FIG. 7A.
- an inside diameter of approximately five inches or larger may allow the mounting block 20 and portions of conductor plate 30 and flexures 40 to be mounted internally to pole 1002.
- the moving mass and upper portion of plate 30 may protrude from the pole to allow a larger moving mass and flexure displacement range than may be available within the pole.
- the upper end 1004 of pole 1002 and the tuned mass damper 10 may be enclosed within a cover 72 or housing, which may include a portion 74 which extends forward or rearward to accommodate the displacement movement of the moving mass.
- Cover 72 may provide aesthetic aspects to conceal the tuned mass damper and may also protect the tuned mass damper and pole interior from outdoor weather or other ambient conditions.
- Cover 72 may be plastic, metal or made of other materials as desired.
- the tuned mass damper 10 can be mounted externally to a pole 1002, optionally with portions protruding above the pole, as illustrated in FIG. 8.
- a pole with an inside diameter of less than approximately five inches may require the mounting block 20 to be mounted externally to pole 1002.
- a mounting bracket 26 can be used to support and help attach mounting block 20 to upper end 1004 of pole 1002.
- the moving mass and upper portion of plate 30 may protrude in height above the pole to allow a larger displacement range than may be available if the moving mass height overlaps with the upper end of the pole.
- a cover or housing may be used to conceal and protect the tuned mass damper and upper pole end.
- FIG. 9 Portions of an alternate embodiment of a tuned mass damper 110 are illustrated in FIG. 9.
- the illustrated portion of tuned mass damper 110 includes a base or mounting block 120, a flexure 140 with a lower end 142 and an upper end 144 and a subassembly including a magnet block 150 and a ballast block 156.
- a magnet 152 is mounted in magnet block 150 within a magnet housing 154.
- the upper end 144 of flexure 140 defines at least one and optionally a pair of mounting slots 146. Fasteners extend through slots 146 to connect magnet block 150 to ballast block 156 as a subassembly on opposing sides of flexure upper end 144.
- Slots 146 are arranged to have a vertical length, allowing the fasteners to be selectively placed in height within the range defined by slots 146. 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.
- One base, flexure and subassembly portion of tuned mass damper 110 are shown for purposes of illustration. A symmetric base, flexure and subassembly are arranged on the opposite side of a conductor plate and attached via a top plate, comparable to the arrangement of tuned mass damper 10.
- 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.
- An alternate damping mechanism can incorporate a mass suspended between springs or a spring or within an elastic type of material, such as a mass suspended or encapsulated within a rubber piece or between rubber cables.
- the mass can be supported on rollers, sliders or as a hanging pendulum.
- Certain embodiments of the present disclosure include methods for mounting a tuned mass damper on a basketball goal assembly.
- the steps include providing a basketball backboard and rim assembly and optionally also providing a support pole to which the basketball backboard and rim assembly can be mounted.
- the steps include mounting a tuned mass damper assembly to the basketball backboard and rim assembly.
- this includes mounting the tuned mass damper adjacent the upper end of the support pole.
- the method may include mounting a base or mounting block to the basketball goal assembly directly or mounting it adjacent an upper end of a supporting pole.
- the method includes arranging a conductor plate, typically in a fixed position, and arranging the plane of the plate normal to the plane of the backboard. Flexures are arranged on opposing sides of the conductor plate and are arranged to move or bend parallel to plate 30. A moving mass is coupled to the flexures. The movable mass is arranged to extend over the top and across the conductor plate and then downward with portions facing opposing faces of the plate. The method allows the moving mass to move forward or rearward relative to the plate as the flexures bend. Optionally, movement of the moving mass can be limited by arranging bumper pads on the plate.
- the moving mass may be formed with a set of magnet blocks and ballast blocks, for example arranged in an alternating pattern, with a ballast block arranged opposing a magnet block on opposing sides of the plate, and also with a ballast block arranged opposing a magnet block on opposing sides of each flexure.
- the magnet blocks and ballast blocks are configured as symmetric subassemblies on opposing sides of the plate, with each subassembly clamped to a respective flexure.
- the subassemblies are connected via a top plate.
- the method includes arranging a pair of magnets within the moving mass, with a magnet arranged in each magnet block, and offsetting the magnets from each other on opposing sides of the plate.
- a face of each magnet is arranged parallel to and facing a corresponding face of the plate and is aligned with an opposing ballast block.
- the magnetic poles are arranged perpendicular to the plate.
- the tuned mass damper is mounted adjacent an upper end of a support pole.
- the tuned mass damper can be mounted internally to the pole, optionally with portions placed to protrude upward from the pole.
- the tuned mass damper can be mounted externally to a pole and optionally placed with portions protruding above the pole.
- the damper can be tuned by selectively arranging the subassemblies in height relative to the flexures within a defined range.
- the method includes dissipating energy when an impact force strikes the basketball goal assembly by allowing the moving mass to oscillate forward and rearward on the flexures relative to the conductor plate.
- the method includes operatively mounting the oscillating mass to create a magnetic flux and correspondingly a drag force to damp movement of the basketball goal assembly.
