Abstract
An adjustable basketball goal pivotally secured to a fixed support post with pairs of interengaged pivoted lever arms. A height adjustment mechanism is secured to the support post with a unidirectional activation connection bar extending therefrom pivotally interconnected to a pair of goal lever arm supports. A gear rack portion on the activation connection bar is positioned for registration within a double gear reduction drive engagement assembly having a user engagement crank arm extending therefrom providing selective directional rotation incrementally to elevate and lower the basketball goal in relation to the support post. A handle integrated automatic height adjustment braking system is provided assuring the goal assembly is retained in position during raising and lowering thereof.
Description
- This is a Continuation in Part patent application of Ser. No. 17/319,449, Filed May 13, 2021.
- This invention relates to sport goals, specifically basketball goals that are height adjustable to accommodate different player venues.
- Prior art adjustable basketball goals have been developed that use different goal post support adjustment systems, see for example U.S. Pat. Nos. 5,388,821, 6,273,834, 7,892,118, 8,708,844 and U.S. Patent Publication 2004/0018900A1.
- U.S. Pat. No. 5,388,821 discloses a force lifting adjustment basketball goal having a counterweight with a basketball goal on a support post.
- U.S. Pat. No. 6,273,834 claims a quick release self-adjusting latch for an adjustable basketball goal with a dual arm pivot support and adjustment mechanism having locking key selectively engaged within a plurality of opposing aligned spaced slots.
- U.S. Pat. No. 7,892,118 describes a basketball goal having an adjustable hoop and backboard with an integrated adjustment rack having a remote release activation positioned on the support post.
- U.S. Pat. No. 8,708,844 illustrates a basketball system with a pivoted multi-paired arm adjustable backboard and hoop configuration for vertical adjustment.
- Finally, U.S. Publication 2007/0042843A1 discloses a basketball system having a basketball goal and support structure which is adjustable vertically by engagement of a pair of parallel spaced pivoted support arms to support post and a spring-loaded lever action adjustment for height system, all on a support structure which is movably positioned about the venue.
-
FIG. 1 is a side elevational view of the adjustable basketball goal in solid lines and in broken lines indicating height adjustability. -
FIG. 2 is a front elevational view thereof. -
FIG. 3 is an enlarged perspective view of the gear reduction ratchet height adjustment assembly with portions broken away. -
FIG. 4 is a side elevational view thereof with portions broken away and in broken lines illustrating the adjustment engagement achieved. -
FIG. 5 is an exploded perspective view of the rotary ratchet height assembly. -
FIG. 6 is an enlarged exploded perspective view of a pinion shaft and auto braking assembly. -
FIG. 7 is an enlarged perspective view of the first reduction gear and drive pinion gear. - A height adjustable basketball goal pivotally secured to a support post having an adjustable rotary lift double gear reduction drive gear assembly secured to the ends of a pair of goal level support arms and pivotally secured and extending beyond the support post allowing for incremental vertical adjustment of the basketball goal on the support post.
- Referring now to
FIGS. 1 and 2 of the drawings, a rotary liftadjustable basketball goal 10 of the invention can be seen having a hollowsupport post member 11. Pairs of vertically spaced upper and lower basketball backboard supportarms support arm pairs backboard 14 which includes a basketball rim andnet assembly 15 as will be well understood by those skilled in the art. The backboardsupport arm pair 12 is pivotally secured on their respective proximal ends to apertured mounting brackets extending from therespective side surfaces support post 11 and its upper end designated as 16. - Correspondingly, the backboard
support arm pairs 13 are pivotally secured to and extend beyond thesupport post 11side surfaces support arm pairs 12 pivot point at 17. - It will thus be seen that a dual pivot point orientation of the parallelogram spaced upper and lower basketball backboard
support arm pairs backboard 14 while maintaining thebackboard 14 in parallel vertical relationship to thesupport post 11 and keeping the basketball rim andnet assembly 15 on a horizontal plane regardless of its vertical position. - A pivoting backboard
activation connection bar 18 is pivotally connected to and between the respective aperturedends 13B of the backboardsupport arm pairs 13. Thebackboard activation bar 18 extends therefrom in parallel aligned spaced relation along thesupport post 11 and has an engagement gear rackinsert surface portion 18A thereon, best seen inFIGS. 1, 3 and 4 of the drawings for registration with a rotary dual gear reduction type actuatingheight adjustment assembly 19. The rotary actuatorheight adjustment assembly 19 is mounted between a pair of aperturedsupport brackets support post 11back surface 11C. The rotary actuatorheight adjustment assembly 19 has an open-ended housing 22 with a handle fitting 23 for receiving a userengagement crank handle 24 extending therefrom with anautomatic braking assembly 25 best seen inFIGS. 2, 3 and 6 of the drawings. - Referring now to
FIGS. 5 and 6 of the drawings, thecrank handle 24 is threadably secured onto apinion shaft assembly 26 with anautomatic braking assembly 25 components including abrake disk 24A,ratchet socket 25B, and a bushing 25D. A compression spring andcap lock assembly 27 is positioned on the end of thepinion shaft assembly 26 which imparts rotational input from the crank handle to afirst pinion gear 28 to a reductionmain gear 29 having a secondreduction pinion gear 30 extending therefrom, as best seen inFIG. 7 of the drawings. - The
activation connection bar 18 pivotally attached to the end of thebackboard support arms insert surface portion 18A which is guidably positioned through theadjustable drive assembly 19 by a synthetic frictional guidetop cap 31A and an internal frictionguide pad channel 31B. - It will be evident from the above description that selective uni-directional rotation of the
crank arm 24 on thepinion shaft assembly 26 will rotate thefirst pinion gear 28 in communication with the first reductionmain gear 29 and therefore its correspondingly second gearreduction pinion gear 30 whosegear teeth 30A will therefore engage and selectively raise or lower thebackboard activation bar 18 and thereby the pivotally attachedbasketball backboard 14 as hereinbefore described. - Retained advancement of the
backboard activation bar 18 andbasketball backboard 14 is maintained by the unidirectional height adjustmentautomatic brake assembly 25 which controls the rate of descent as will be understood by those skilled in the art. - As it will be seen, the rotary lift mechanism of the present invention for adjustable height basketball system utilizes the double gear reduction system in tandem with an
automatic brake assembly 25 that enables the user to easily raise and lower thehoop assembly 25 by simply turning thecrank 24 one way or the other. This system, as described, does not require the user, not shown, to manually select an up or down mode only one interface point with thecrank handle 24 is needed. It will therefore be evident that the current system's advantages over prior art is the speed and effort required to raise the rim andnet assembly 15 from low setting to a high setting which can be achieved in a reduced number of rotations of thecrank 24 with less effort in a shorter period of time. It will also be evident that the user can make the rim andnet assembly 15 go up and down at any time by choosing to turn thecrank 24 during clockwise rotation to raise the hoop, therotary ratchet assembly 25C clicks on theratchet sprocket 25B to lift the system incrementally, as described, and correspondingly if the user rotates the handle counter-clockwise direction to lower the rim andnet assembly 15, theautomatic brake assembly 25 gradually slips allowing the rim andnet assembly 15 to come down. It will be seen that the rim andnet assembly 15 will only come down gradually as thebraking assembly 25 will immediately engage if thecrank handle 24 is released. It will therefore be seen that the combination of speed and safety overcomes many of the typical complaints of current prior art systems which tend to be cumbersome, time consuming and require more effort. - It will thus be seen that a new and novel rotary lift adjustable basketball goal has been illustrated and described and it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention. Therefore, I claim:
