Abstract
A basketball backboard mounting system includes a stationary member that provides support for a basketball backboard assembly. The mounting system combines a support system including a plurality of hollow members and an actuator system for easily adjusting the support system. The support system includes a stationary member mounted perpendicularly with respect to a floor. The actuator system includes a plurality of adjustable brackets which attach to a basketball backboard, an adjustable structural member which is in slidable contact with the stationary member, and a drive mechanism which easily adjusts the height from the floor of the basketball backboard assembly. The adjustable structural member is telescoping and provides enough support to a basketball backboard to eliminate potentially damaging torsional forces on the basketball backboard.
Description




BACKGROUND OF THE INVENTION




This invention relates generally to basketball backboards and, more particularly, to adjustable height mounting systems for basketball backboards.




A basketball backboard is normally supported from above so that a basketball rim mounted to the backboard is positioned at a height of ten feet above a floor. This height is formidable for shorter players and nearly impossible for children. Adjustable-height backboard supports permit the basketball backboard to be lowered so that the basketball rim is positioned at a height of eight feet for grade-school gymnasiums. Unfortunately, typically, these basketball backboard assemblies require tedious on-site assembly and the installation of additional support tubing and a crank-type adjustment assembly. Furthermore, often these systems are supported from below, creating a potential hazard near a basketball court.




While these assemblies position a basketball rim eight feet above the ground, the assemblies typically require continuous maintenance including re-tightening of the installed components. Although crank-type adjustments are installed, the systems are unreliable, time-consuming, and difficult for an individual to adjust. Furthermore, the assemblies are typically not supported as rigidly as the non-modified equipment and over time the additional support tubing fatigues and requires replacement.




Accordingly, it would be desirable to provide a basketball backboard assembly that can be easily adjusted by an individual, does not require continuous maintenance, and is easily adapted to existing overhead basketball backboard assemblies.




BRIEF SUMMARY OF THE INVENTION




In an exemplary embodiment of the invention, an adjustable height basketball backboard mounting system provides a reliable mounting system that easily attaches to existing support systems and is quickly adjustable by an individual.




The basketball backboard mounting system includes a stationary member that provides support for a basketball backboard assembly. The mounting system combines a support system that includes a plurality of hollow members and an actuator system for easily adjusting the support system. The support system includes a stationary member mounted perpendicularly with respect to a floor. The actuator system includes a plurality of adjustable brackets which attach to a basketball backboard, an adjustable structural member which is in slidable contact with the stationary member, and a drive mechanism which easily adjusts the height from the floor of the basketball backboard assembly.




As a result, a basketball backboard assembly is easily adjustable by an individual, is rigid enough not to require continuous maintenance, and is easily assembled when compared to known adjustable backboard assemblies.

includes a bracket clamp


46


attached to stationary member


24


. First angled support member


38


is attached to bracket clamp


46


with a pin


48


such that angled support system


26


is capable of retracting stationary member


24


which causes backboard


12


to be suspended such that backboard


12


is substantially parallel to the floor. The second angled support member is attached to stationary member


24


in a similar manner.




Actuator system


28


includes an adjustable member


50


having a first end


52


and a second end


54


, and a drive mechanism assembly


56


. Adjustable member


50


is a telescoping member that is hollow and tubular and includes an outer surface


58


. Adjustable member


50


includes an axis of symmetry


59


which extends from first end


52


to second end


54


. Adjustable member


50


is positioned within stationary member


24


in slidable contact. In one embodiment, outer surface


58


of adjustable member


50


is in slidable contact with the inner surface of stationary member


24


. In a second embodiment, outer surface


30

is positioned above the floor after adjustable member


50


is positioned.




Drive mechanism assembly


56


includes a rod


70


having a first end


72


and a second end

56


also includes a thrust bearing


86


mounted to a fixed bracket


88


and including an opening


90


. Thrust bearing


86


prevents axial movement of backboard


12


. Fixed bracket

is attached between adjustable member


50


at second end


54


and backboard


12


at lower attachment


20


. A plurality of threaded connectors


92


extend through backboard


12


and connect rim


14


to fixed bracket


88


. Attaching rim


14


to fixed bracket


88


eliminates an amount of potential strain which would be induced on backboard


12


if fixed bracket


88


was attached directly to backboard


12


.




Fixed bracket


88


includes an opening


94


. Thrust bearing or collar


86


is mounted to fixed bracket


88


such that opening


90


is positioned concentrically over opening


94


so that rod


70


can extend therethrough. Opening


94


is sized to receive rod


70


, but closed eyelet loop


80


cannot fit within opening


94


and as such, closed eyelet loop


80


is a limit to the upward movement of adjustable member


50


. For example, when closed eyelet loop


80


is in a position of close proximity to second end


34


of stationary member


24


, as shown in

FIG. 1

, the height of backboard


12


from the floor is maximized and mounting system


10


is in a “fully elevated” position. In one embodiment, a maximized height of rim


14


when backboard


12


is in a “fully elevated” position is 10 feet above the floor.




Drive mechanism assembly


56


also includes a roller assembly


98


and a stationary nut


100


including an opening


102


which receives threads


76


of rod


70


. Opening


102

70


is received therethrough, but thread stop


78


cannot fit within opening


102


. Thread stop


78


prevents rod


70


from slipping through nut


100


. Opening


102


is also sized such that as rod


70


is adjusted upwardly, thrust bearing


86


will contact stationary nut


100


and will not enter opening


102


. Nut


100


is fixedly mounted to a bracket


104


attached to stationary member


24


in close proximity to second end


34


. Drive mechanism assembly


56


is positioned such that rod


70


extends through fixed bracket


88


and thrust bearing


86


into stationary nut


100


in a direction substantially parallel to axis of symmetry


36


. Roller assembly


98


, described below in

FIG. 5

, is attached to backboard


12


at upper attachment


18


and is slidably attached to stationary member


24


.





FIG. 2

is a side view of mounting system


10


in which closed eyelet loop


80


is positioned in distant proximity to second end


34


of stationary member


24


. When closed eyelet


80


has been fully rotated clockwise, thread stop


78


contacts stationary nut


100


and stops the rotation of rod


70


and the downward movement of adjustable member


50


. The height of backboard


12


from the floor is minimized and mounting system


10


is in a “fully lowered” position. In a one embodiment, rim


14


is 8 feet above the floor when mounting system


10


is in a “fully lowered” position.




In operation, a crank end (not shown) is upwardly extended and inserted into closed eyelet loop


80


. The crank is rotated counter-clockwise to raise rim


14


and clockwise to lower rim


14


. The movement of rod


70


is limited in a counter-clockwise direction by thrust bearing


86


and in a clockwise direction by thread stop


78


. As the crank is rotated clockwise, closed eyelet loop


80


is rotated which causes rod


70


to rotate. As rod


70


rotates, threads


76


are rotated clockwise through stationary nut


100


causing rod


70


to extend downwardly towards the floor in a direction parallel to axis of symmetry


36


. As rod


70


extends downward, fixed bracket


88


and roller assembly


98


slide downward causing adjustable member


50


to simultaneously extend downward. The crank is continuously rotated until marking


60


indicates that adjustable member


50


is positioned at a desired height for rim


14


. To raise rim


14


, the crank is continuously rotated counter-clockwise until marking


60


indicates that adjustable member


50


has positioned rim


14


at a desired height.
