The present application is a continuation of U.S. patent application No. 13/490,561, filed Jun. 7, 2012. U.S. patent application Ser. No. 13/490,561 is a continuation of U.S. Pat. No. 8,206,247, issued Jun. 26, 2012, both of which are hereby incorporated by reference in their entirety.


FIELD OF THE INVENTION
The present invention deals with basketball goals, and specifically deals with an arrangement to mount a basketball backboard and a rim to a support arrangement.
BACKGROUND OF THE INVENTION
With the rise in popularity of the sport of basketball and the frequency of larger players, it has become a well-known and sensational shot to “slam dunk” or dunk the ball. When a player dunks the ball, the player jumps to a position adjacent to and preferably above the basketball rim, stuffs the ball through the net, and may impact, hold or hang from the basketball rim. In such a situation, the sudden impact force combined with a rigid rim structure can lead to injury of the player or damage to the rim and/or backboard. As a result, resilient breakaway basketball rims have become popular.
A typical breakaway basketball goal includes a rim assembly including a rim and an attachment bracket. The attachment bracket is attached to the backboard. Frequent impacts and/or sudden shear pressures can wear on the bracket, leading to breakage of the bracket and/or backboard. Accordingly, there is a need for a safer backboard and basketball rim mounting system. The present invention addresses these needs.

DESCRIPTION OF PREFERRED EMBODIMENTS
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations, modifications, and further applications of the principles of the invention being contemplated as would normally occur to one skilled in the art to which the invention relates.
Certain embodiments of the present system deal with a basketball goal assembly which adjustably supports a backboard assembly and a rim assembly to enable players to play the game of basketball. In certain preferred aspects, the rim assembly is connected directly to the support arrangement so that force applied to the rim assembly and is not transferred to the backboard assembly.
Generally, basketball system 10 as shown in FIGS. 1-7 includes a support element extending upward from a support surface. An adjustable parallelogram structure extends on a forward side of the upright to support and holds the backboard assembly 90 and the rim assembly 100. A portion of the parallelogram structure extends rearwardly of the support element and can be moved upward or downward, for example with a telescoping cylinder connected to the upright, to adjust the height of the backboard assembly and rim assembly relative to the support surface is transmitted directly to the support
In the illustrated embodiment of FIGS. 1-3, assembly 10 includes an upright support 20 typically formed as a vertical tube or pole. In certain preferred embodiments, the support 20 defines a vertical pole axis P-P perpendicular to the support surface, although in certain less preferred embodiments an angled upright may be used. Support 20 has a lower end 22 supported by a support surface, typically through an in-ground installation or on a portable base. Support 20 has an upper end 24 to which the parallelogram assembly 40 is mounted.
Parallelogram assembly 40 includes at least one and preferably a pair of upper arms 42 pivotally mounted adjacent their rearward ends 44 to points adjacent upper end 24 of the support, and at least one and preferably a pair of lower arms 52 also pivotally mounted to points adjacent the upper end 24 of the support 20. In the illustrated embodiment, rear portions 54 of lower arms 52 include an extension portion 58 extending rearwardly of support 20. Extension end 58 is pivotally mounted to an upper end of a telescopic extension cylinder 30 which extends downward and is linked to a midpoint of support 20. The lower end of cylinder 30 is connected at a pivot point 25 to a pair of flanges 26 mounted on the rear face of support 20. A crank member 32 can be controlled by a user to extend or retract telescoping cylinder 30 and to correspondingly raise or lower extension end 58 of the parallelogram structure. Telescoping cylinder may have a round, square or alternate cross-section. Extension end 58 may alternately be a rearward portion of one or both of upper arms 42.
As seen most clearly in FIGS. 2, 5 and 6, a pair of forward “Y” arms 70 have lower ends 74 connected to the forward ends 56 of lower arms 52, central points 76 pivotally connected to the forward ends 46 of upper arms 42 and upper ends 72 which are mounted to the backboard assembly 90. In certain embodiments the upper ends 72 are connected to opposite vertical side edges of backboard assembly 90. In some embodiments, upper ends 72 are connected to backboard assembly in a non-pivoting fixed angular arrangement. As illustrated, forward arms 70 include central portions 78 between central points 76 and lower ends 74 and offset lengths 79 to offset the upper ends horizontally outward from said central pivot points. In alternate embodiments only one arm or a different arrangement of arms can extend from the parallelogram assembly 40 to support the backboard assembly 90.
Preferably the four pivot points or pairs of pivot points defined by arms 42, 52 and 70 and support 20, namely upper rear pivot points 45, lower rear pivot points 55, upper forward pivot points 47 and lower forward pivot points 57 define an adjustable parallelogram structure which causes upper arms 42 and lower arms 52 to remain in parallel during adjustment of the parallelogram.
As shown in further detail in FIGS. 3, 4 and 5, in the illustrated embodiment a crossbar 79 extends between central portions 78 of forward arms 70. A brace arm 80 extends forward along axis F-F from a rear end 82 mounted to crossbar 79 to a forward end 84 connected to a forward bracket 86.
Basketball rim assembly 100 includes a rim 102 and a rearward bracket 104. Basketball rim 102 typically extends forward from bracket 104. Backboard assembly 90 includes a backboard panel member 92 in a vertical plane along axis B-B. The backboard panel is made of sheet material such as glass, acrylic or wood and is preferably surrounded by a peripheral frame 94. Frame 94, for example, can be an aluminum frame. Preferably, panel 92 defines a panel opening 96 in substantially a size and shape, for example a square or rectangle, to allow passage of a connection from rim bracket 104 to forward bracket 86. An optional spacer pad 110 may be used between rim bracket 104 and forward bracket 86. Forward bracket 86 may also be secured, for example at its lower edge to the backboard assembly frame 94 to assist in maintaining the backboard assembly stable and in a desired vertical axis B-B.
Rim assembly 100 is not connected to backboard panel 92. In certain embodiments, rim bracket 104 is directly and securely connected to forward bracket 86 through opening 96, for example with four bolts. As such, force transmitted to the rim assembly 100 is directly transmitted to bracket 86 and brace 80 without applying stress or force to the backboard panel.
In certain preferred embodiments, axes of forward arms 70, brace 80 and backboard assembly 90 form a fixed triangle as seen in FIG. 6. Specifically, axes A2-A2, B-B and F-F are connected at fixed angles θ, α and β which do not pivot or change as the height of backboard assembly 90 is raised and lowered. Further, by maintaining non-vertical axis A2-A2 parallel to non-vertical fixed axis A1-A1 associated with vertical support 20, the linkage maintains backboard axis B-B is a substantially vertical orientation perpendicular to the support surface regardless of height.
Illustrated in detail in FIG. 7, lower rear pivot point 55 is preferably mounted to upright 20 at a distance offset rearward from pole axis P-P of support 20, for example with a bolt or axle through a rear pivot channel 28. Preferably upper rear pivot point 45 is mounted to upright 20 at a distance offset forward of pole axis P-P, for example using a bolt or axle extending through a forward pivot channel 29. As example, pivot channels 28 and 29 may be formed by drilled holes in support 20 or by pivot tubes welded to support 20. Preferably the respective offset distances of lower rear pivot point 55 and upper rear pivot point 45 define a non-vertical angled axis A1-A1 at a fixed angle relative to pole axis P-P and forming one side of the parallelogram arrangement. The longitudinal axis of A2-A2 of forward arms 70 is parallel to axis A1-A1. In alternate embodiments, the upper rear pivot point can be mounted rearward of axis P-P and the lower pivot point is mounted forward, with a corresponding angular change in the forward arms, brace and fixed triangle mounting of backboard assembly 90.
In operation, crank 32 may be turned by a user to extend or retract cylinder 30 and to correspondingly raise or lower extension end 58 of the parallelogram relative to pivot point 25. Pivotal movement of the rearward extension end 58 around lower rear pivot point 55 correspondingly lowers or raises the forward end 56 of lower arms 52 and through the linkage arrangement correspondingly raises and lowers upper arms 42 and forward arms 70. Raising and lowering of forward arms 70 controls the raising and lowering of backboard assembly 90 and correspondingly rim assembly 100 to a desired height.
The goal assembly may be made from standard materials such as steel or stainless steel. The pole, support arms and rim assembly may be painted for distinctiveness or decoration and to protect the metal of the goal assembly.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
