Portable folding basketball goal system

A portable, folding basketball system employing a unique design to allow manual manipulation of the system from an extended position suitable for game play and a retracted position for compacted storage of the system. The system comprises a plurality of pole sections which form a pole of variable height, a base pivotally connected to the pole and having a recess for receiving the pole, a support arm pivotally connected to the base, a collar pivotally connected to the support arm and slidably engaging the pole, a bracket assembly pivotally connected to the pole, a backboard connected to the bracket assembly, and a rim assembly pivotally connected to the backboard. In the extended position the pole is generally directed upward at a playable height, the rim is in the horizontal position, and the backboard is in a playable position. In the retracted position, the pole is reduced in height and is nested within the recess of the base, the rim is disposed generally parallel to the backboard, and the backboard and bracket assembly are pivoted so that the majority of the backboard is disposed below the upper pole end.

BACKGROUND OF THE INVENTION 
1. The Field of the Invention 
The present invention is related to a portable basketball goal assembly 
which may be compacted for storage. More particularly, the present 
invention is related to a portable basketball goal system employing a 
unique design to enhance the compacted storage of the basketball goal 
system. 
2. Technical Background 
As the game of basketball has increased in popularity a greater number of 
people have purchased basketball goals for use at their homes. Such goals 
are typically permanently mounted such that the driveway of the home 
serves as the basketball court, as few homes have sufficient land 
surrounding the home to dedicate space for exclusive use as a basketball 
court. In some instances, locating where to mount a basketball goal can 
pose some difficulties. For example, in some homes, permanently mounting a 
basketball goal next to the driveway could provide a risk to traffic in 
the driveway, resulting in danger or damage to both automobiles and the 
goal system. 
In some cases, the only viable location for mounting a basketball goal is 
in a location where permanently mounting a goal cannot be easily 
accomplished. Such a location may be where there is concrete or asphalt on 
the ground; thus, to mount the goal would require breaking a hole in the 
concrete or asphalt and then repairing the hole after the pole has been 
affixed in the ground. Such a procedure could be expensive and would most 
likely leave the driveway appearing unsightly. 
Permanently installed outdoor basketball goals suffer from other 
disadvantages as well. Because they are permanently mounted, they are 
generally exposed to the weather throughout the entire year. Constant 
exposure to the weather can cause the goal system to prematurely wear by 
promoting oxidation. Premature oxidation can be particularly troublesome 
in goals having moving parts, such as goals that employ adjustable height 
or breakaway goal mechanisms. Constant exposure to the weather can cause 
these mechanisms to prematurely fail. 
Even permanently mounted basketball goals utilized in indoor environments 
suffer from some disadvantages. For example, a typical school has a 
gymnasium which must serve many purposes. Having several basketball goals 
permanently mounted for use in the gymnasium may preclude or at least 
interfere with certain other activities. On formal occasions, objection 
may be made to the appearance of permanently mounted basketball goals. 
In response to these and other disadvantages inherent in permanently 
mounted basketball goals, some designs of portable basketball goals have 
been developed. In order for a portable goal to be effective, sufficient 
weight must be employed to maintain the goal in a generally rigid position 
for use in playing the game of basketball. Hence, some portable designs 
utilize a great deal of weight, making the goals particularly difficult to 
move and possibly requiring the assistance of several people to set up or 
remove the goal. Additionally, such designs can be prohibitively expensive 
for people desiring to purchase one for use at their home. 
Some prior-art designs have utilized removable weights, such as sand bags 
or metal weights, for use on the support structure. A principal 
disadvantage to the use of these types of removable weights is that they 
can be extremely heavy. While the support and the goal systems employing 
such designs may be easier to move, the weights are not. Some such 
designs, in an attempt to minimize the amount of removable weights 
required, are extremely large and bulky because they employ long lever 
arms in order to increase the effective weight of the removable weights. 
In an attempt to make a portable basketball goal system that would be ideal 
for use at home, some designs have employed a base with a hollow cavity 
for receiving a ballast material. The ballast material may be water, sand, 
or other suitable material. Such systems can be easily moved to a desired 
location where the base is then filled with the ballast material, thereby 
providing sufficient weight to maintain the goal in a generally rigid 
position for use in playing basketball. When it is desired to move the 
goal, the ballast material is emptied out and the goal moved. The 
principal advantage of such a goal is in the use of the ballast material. 
Water and sand are inexpensive and convenient to use. Such ballast filled 
goal designs do suffer from some disadvantages, however. Having to fill 
and empty the goal each time the goal is to be set up or moved requires 
time and is an inconvenience. This procedure is particularly difficult if 
the goal is being used indoors. Furthermore, if water or sand is used, a 
large quantity will be required to effectively support the goal in a 
generally rigid position. Thus, when emptying the ballast material out of 
the goal, precautions have to be taken to ensure that the material is 
properly directed so it does not cause damage to the home or other 
surroundings. Also, the utilization of a water-filled base presents the 
hazard that the base receptacle or container aspect could be broken if the 
water within the base freezes and expands. 
An almost universal disadvantage to the use of any portable basketball goal 
system is that they are difficult to store. A standard height basketball 
goal is approximately 12 feet. Few people have garages or storage sheds 
that will accommodate a 12 foot apparatus. Thus, such portable goals are 
usually stored in a horizontal position. Of course, storing a basketball 
goal system in a horizontal position takes up substantial floor space. 
Some garages or storage sheds do not have sufficient floor space to store 
a goal, forcing the owner to store the goal outside, thereby eliminating 
some of the advantages of the portable goal system. 
One method of reducing the height of the basketball goal system is to have 
a height adjustable pole as is disclosed in U.S. Pat. No. 5,375,835 issued 
to Van Nimwegen et al. However, the amount that the pole can be decreased 
in height is limited and the backboard still adds additional height to the 
system. Height may be further decreased by removing the backboard but this 
is inconvenient as backboards are typically securely attached to the pole 
by bolts or screws. Furthermore, it is advantageous to retain connection 
of all parts of the basketball goal system for convenience and to prevent 
loss. 
Because the base of the basketball goal system must be large enough to 
provide sufficient support for the system, the base requires a substantial 
amount of floor space. A base can typically require between 6 and 10 
square feet of floor space for storage. Thus, even if the basketball goal 
system vertically fits in the garage or shed it may not be stored there 
for lack of floor space. 
Thus, it would be an advancement in the art to provide a portable support 
for a basketball goal system which can use a ballast material for weight 
but can also be easily stored by one person without having to remove the 
ballast material. 
It would also be an advancement in the art to provide a portable basketball 
goal system which decreases the maximum vertical height of the basketball 
goal system by reducing the vertical extension of the backboard and the 
height of the pole, thereby facilitating storage of the system. 
It would be a further advancement in the art to provide a portable 
basketball goal system which would allow manipulation of the base, pole, 
backboard, and rim to position such members in substantially the same 
plane thereby permitting the system to be stored in a generally vertical 
position and reducing the amount of floor storage space. 
It would be yet another advancement in the art to permit manual 
manipulation of the basketball goal system for storage while maintaining 
the interconnection of the rim, backboard, pole, and base. 
Such a device is disclosed and claimed herein. 
BRIEF SUMMARY AND OBJECTS OF THE INVENTION 
The present invention is directed toward a portable, folding basketball 
goal system employing a unique design for manual manipulation into an 
extended position for use in game play and into a retracted position for 
compacted storage. The basketball goal system is designed to be stored 
with a reduced height and in a vertical position with all members of the 
system generally along the same vertical plane. The unique storage design 
reduces the amount of vertical space and floor space required to store the 
basketball goal system. 
In one presently preferred embodiment, the basketball goal system comprises 
a plurality of pole sections which assemble to form a pole with a base end 
and a backboard end. The pole sections are configured to allow height 
variance in the pole. The pole is pivotally attached at the base end to a 
base. The base is configured with a recess on its exterior surface which 
runs from the proximal end to the distal end of the base. The pole is 
pivotally connected in the recess of the base near the proximal end of the 
base. The pole pivots from an extended position where the pole is 
generally directed upward for use in game play to a retracted position 
where the recess of the base receives the pole for compacted storage. When 
the pole is extended upward for use in game play, the pole may be 
substantially vertical to the playing surface or angled slightly to extend 
the backboard above and away from the base. 
In one presently preferred embodiment, the base is configured with a cavity 
for receiving a ballast weight such as sand or water. This is necessary so 
that the base can fully support the basketball goal system during rigorous 
game play. In such an embodiment, the base is configured with an opening 
near, but spaced from, the top portion of the base such that when the base 
is filled with water to the point that the water level in the base reaches 
the opening, a void remains within the top of the cavity which does not 
fill with water. This is to allow expansion of the water in the case of 
freezing. A cap is also provided for covering the opening thereby 
preventing displacement of the ballast material. Alternatively, the base 
may be made of sufficient weight to act as a ballast in order to ensure 
the stability of the basketball goal system. The base is designed such 
that the height of the base slightly increases towards the distal end of 
the base. The effect of this design is that there will be more ballast 
material, and hence more weight, further from the proximal end of the base 
and thereby provide greater stability to the basketball goal system. 
The basketball goal system may be moved by pivoting the basketball goal 
system about the proximal end of the base. A set of wheels are provided at 
the proximal end of the base for contacting the ground upon pivoting the 
system about the proximal end. With the entire basketball goal system thus 
tilted, the system may be easily moved for short distances. 
The basketball goal system further comprises at least one support arm which 
pivotally connects to the base and to a slidable contractible collar. The 
collar slidably engages the pole. Thus, the support arm provides 
connecting support between the pole and the base. The collar slides along 
the pole while the support arm pivots near the base. This allows the 
support arms to move in conjunction with the pole from the extended 
position and the retracted position. Preferably, a collar fastener is 
connected to the collar. As the collar fastener is tightened, the collar 
is constricted to secure the position of the collar on the pole and to 
prevent pivotal movement of the pole. Alternatively, the collar fastener 
may be loosened which expands the collar and allows movement of the collar 
and pivotal movement of the pole. Thus, by means of the collar and collar 
fastener, the pole may be secured in either the extended position or the 
retracted position. 
In one presently preferred embodiment, the basketball goal system further 
comprises a bracket assembly which has two parallel members which are 
pivotally connected near the backboard end of the pole. The pivotal 
connection is achieved by a bracket pin which is disposed on the bracket 
assembly and runs through the pole. The members run generally parallel to 
the pole, on opposing sides of the pole, and form a channel. This channel 
receives the pole when the basketball goal system is in the retracted 
position as described below. 
A backboard is connected to the bracket assembly. The backboard and bracket 
assembly pivotally move together over the backboard end of the pole from 
the extended position to the retracted position. In the extended position 
the majority of the backboard extends further distal from the base than 
the backboard end of the pole. This provides a maximum height for the 
system. In the retracted position the majority of the backboard extends 
further proximal to the base than the backboard end of the pole which 
reduces the height of the system. 
In one presently preferred embodiment, the invention further comprises a 
bracket lock pin which is disposed on the bracket assembly and is used to 
secure the backboard into the extended position. The bracket latch is 
received by a lock opening disposed on the pole. This secures the proper 
position of the backboard during rigorous game play. As stated previously, 
in one preferred embodiment, the pole is nested in the channel formed by 
the members of the bracket assembly in the retracted position. 
A rim assembly, comprising a rim and a rim mount, is pivotally connected to 
the backboard. The rim pivotally moves from the extended position where 
the rim is generally disposed perpendicular to the backboard for game play 
and the retracted position where the rim is generally disposed parallel to 
the backboard for compacted storage. In one presently preferred 
embodiment, pivotal connection of the rim is achieved by the use of a "U" 
bolt which is disposed through the backboard and through slots in the rim 
mount. The slots in the rim mount are sufficiently sized to allow pivotal 
movement of the rim mount about the "U" bolt. Biasing means are secured to 
the "U" bolt to ensure the position of the rim in either the extended 
position or the retracted position. The invention also comprises a rim 
latch which is disposed on the backboard. In the extended position, the 
rim latch is disposed through an opening in the rim mount thereby securing 
the position of the rim in a position generally perpendicular to the 
backboard. The rim latch ensures the stationary placement of the rim in 
the extended position during rigorous game play. 
Thus, in the extended position, the basketball goal assembly has a base 
disposed horizontal to a play surface and a pole directed generally 
upward. The support arms extend from the base to the pole at angle and 
connect to the collar. The collar is tightened around the pole thereby 
securing the position of the pole in a generally upward direction. The 
backboard is secured near the backboard end of the pole such that the 
majority of the backboard extends further distal from the base than the 
backboard end of the pole. The backboard is disposed so that the top 
portion of the backboard is above the bottom portion of the backboard as 
is conventional for game play. The rim extends horizontally from the 
backboard for game play. 
When storage is desired, the rim latches are unfastened and sufficient 
manual force is applied to the rim to overcome the biasing means and 
pivotally move the rim from a horizontal position to a vertical position 
where the rim is generally parallel to the backboard. The bracket lock pin 
is removed from the lock opening thereby allowing pivotal movement of the 
backboard. The backboard and bracket assembly pivotally move about the 
pole from the top portion being above the bottom portion with the majority 
of the backboard extending further distal to the base than the backboard 
end of the pole to the retracted position where the bottom portion is 
above the top portion with the majority of the backboard extending further 
proximal to the base than the backboard end of the pole. Next, the pole 
sections are adjusted to reduce the height of the pole. By pivoting the 
backboard and reducing the pole height, the total height of the basketball 
goal assembly can be reduced from 12 feet to approximately 8 feet which is 
a more feasible storage height. 
The collar fastener is loosened thereby expanding the collar and permitting 
the collar to slide along the pole. The pole is tilted from its generally 
upward position until it lies generally within the recess of the base. The 
collar fastener may then be tightened to constrict the collar and secure 
the pole in the retracted position. The entire basketball goal system is 
pivoted about the proximal end of the base where the base wheels contact 
the ground surface. The basketball goal system is then positioned adjacent 
to a vertical surface, such as a wall, for vertical storage of the system. 
In this manner, compacted storage of the basketball goal system is 
achieved along a vertical plane thereby minimizing storage space. 
Thus, it is an object of the present invention to provide a basketball goal 
system with a base having sufficient ballast to support the system while 
still being portable for storage without removing the ballast. 
It is an additional object of the present invention to provide a basketball 
goal system which allows manipulation of the backboard and pole to 
decrease the maximum vertical height of the basketball goal system for 
storage purposes, thereby facilitating storage of the system in a garage 
or storage shed. 
A further object of the present invention is to provide a basketball goal 
system which can be compacted for storage in which the compacted base, 
backboard, rim, and pole all lie substantially along the same vertical 
plane to reduce the amount of floor space for storage, thereby 
facilitating storage of the system in a garage or storage shed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Reference is now made to the figures wherein like parts are referred to by 
like numerals throughout. With particular reference to FIGS. 1 and 2, a 
portable, folding basketball goal system according to the present 
invention is generally designated 10. As shown in FIGS. 1 and 2, the 
basketball goal system is positioned in its extended position suitable for 
use in game play. 
The basketball goal system includes a base 12. In one preferred embodiment 
the base is made of a low-density linear polyethylene, although one of 
skill will appreciate that a variety of materials may be employed. The 
base 12 has a proximal end 14 and a distal end 16. The base 12 is 
configured with a recess 18 on its upper exterior surface 20 which runs 
from the proximal end 14 to the distal end 16 of the base 12. In one 
presently preferred embodiment, the base 12 is designed to be filled with 
a ballast material to give the base 12 sufficient weight to support the 
basketball goal system and maintain the system in a relatively stationary 
disposition. The base 12 is further designed such that the height of the 
base 12 slightly increases towards the distal end 16 of the base 12. The 
effect of this design is that there will be more ballast material, and 
hence more weight, further from the proximal end 14 of the base 12 which 
provides greater stability to the basketball goal system. 
With reference to FIG. 3, the base 12 is shown with a cavity 22 for 
receiving a ballast weight such as sand or water. This is necessary so 
that the base 12 can fully support the basketball goal system during 
rigorous game play. In such an embodiment, the base 12 is configured with 
an opening 24 near, but spaced from, the upper portion of the base 12 such 
that when the base 12 is filled with water to the point that the water 
level in the base 12 reaches the opening 24, a void remains within the top 
of the cavity 22 which does not fill with water. This is to allow 
expansion of the water in the case of freezing. A cap 26 is also provided 
for covering the opening 24 thereby preventing displacement of the ballast 
material. Alternatively, the base 12 may forgo the use of a cavity and 
comprise sufficient weight to act as a ballast in order to ensure the 
stability of the basketball goal system. 
With reference again to FIGS. 1 and 2, the basketball goal system further 
comprises a plurality of pole sections 28, including at least an inner 
pole section 30 and an outer pole section 32 which mate in a telescoping 
manner to create a pole 34 having a base end 36 and a backboard end 38. 
Such a telescoping pole system is disclosed in U.S. Pat. No. 5,375,835 to 
Van Nimwegen et al. which is incorporated herein by reference. The pole 34 
is adjustable in height by varying the position of the inner pole section 
30 to the outer pole section 32. The inner pole section 30 has an exterior 
surface 40 containing a plurality of depressions 42. The depressions 42 
are preferably formed by pressing rather than punching, so that no hole is 
formed in the exterior surface 40. Instead, a depressed portion of the 
exterior surface 40 is pressed inward. 
A latch 44, pivotally mounted to the outer pole section 32, is configured 
to releasably engage the depressions 42. The depressions 42 are shaped so 
as to permit the inner pole section 30 to move upward without engaging the 
latch 44 and to engage the latch 44 if the inner pole section 30 moves 
downward far enough to bring a depression 42 adjacent the latch 44. Thus, 
the latch 44 is capable of movement between an engaging position for 
engaging a selected one of the depressions 42 and a releasing position in 
which the latch 44 is positioned free of the depressions 42. In this 
manner, the height of the pole 34 may be varied by the telescoping 
movement of the inner pole section 30 within the outer pole section 34 
along a plurality of predetermined positions. 
The base end 36 of the pole 34 extends into the recess 18 for attachment to 
the base 12. With reference again to FIG. 3, pivotal connection of the 
pole 34 to the base 12 is shown. The base 12 is connected to the pole 34 
near the base end 36 of the pole 34 by a pin 46 which is disposed through 
the base 12 and through the pole 34. It is presently preferred that the 
pole 34 meet the base 12 approximately near the proximal end 14 of the 
base 12. The pole 34 pivots about pin 46 from the extended position where 
the pole 34 is generally directed upward for use in game play and the 
retracted position where the pole 34 is nested in the recess 18 of the 
base 12 for compacted storage. The recess 18 also serves to nest the pole 
34 when the basketball goal system is packaged for sale. 
In one presently preferred embodiment, wheels 48 are disposed on the 
proximal end 14 of the base 12 to assist in moving the basketball goal 
system. The wheels 48 are capable of serving as a rotating fulcrum upon 
which the effective weight of the basketball goal system may be supported. 
With the weight of the system on the wheels 48, the system may be 
maneuvered from place to place. The wheels 48 are configured to contact 
the ground surface as the basketball goal system is pivoted about the 
proximal end 14 of the base 12. Thus, the wheels 48 serve as a rotating 
fulcrum and support the effective weight of the basketball goal system 
when the base 12 is tilted from a stationary disposition as the system is 
pivoted about the proximal end 14 of the base 12. 
As shown in FIG. 3A, a rod 50 is disposed through the base 12 and through 
the wheels 48 to serve as an axle for the wheels 48. In an alternative 
embodiment, as shown in FIG. 3B, the rod 50 may also pass through the pole 
34 to provide pivotal connection of the pole 34 to the base 12. Such an 
embodiment eliminates the use of the pin 46. 
With reference to FIGS. 1 and 2, the basketball goal system further 
comprises support arms 52 which pivotally connect to the base 12. The 
support arms 52 connect to the base 12 near the distal end 16 of the base 
12 or approximately midway between the proximal and distal ends 14 and 16 
to allow sufficient pivotal movement of the support arms 52. The support 
arms 52 pivotally connect to a contractible collar 54 which slidably 
engages the pole 34. The collar 54 slides along the pole 34 while the 
support arms 52 pivot at their respective connections with the collar 54 
and with the base 12. This allows the support arms 52 to move in 
conjunction with pole 34 from the extended position and the retracted 
position. A collar fastener 56 is connected to the collar 54. As the 
collar fastener 56 is tightened, the collar 54 is constricted to secure 
the position of the collar 54 and prevent pivotal movement of the pole 34. 
Alternatively, the collar fastener 56 may be loosened which expands the 
collar 52 and allows movement of the collar 52 and pivotal movement of the 
pole 34. Thus, by means of the collar fastener 56, the pole 34 may be 
secured in either the extended position or the retracted position. 
In the extended position, the support arms 52 are generally directed at an 
angle from their pivotal connection with the base 12 to their pivotal 
connection with the collar 54. In this position, the support arms 52 serve 
to support the pole 34 in a generally vertical position. In the retracted 
position, the pole 34 is nested in the recess 18 of the base 12 and the 
support arms 52 generally extend along the same plane as the pole 34 and 
the base 12. In the retracted position, the support arms 52 at least 
partially extend adjacent to the base 12. In one presently preferred 
embodiment, the exterior surface 20 of the base 12 is further configured 
with support arm recesses 57 for receiving at least a portion of the 
support arms 52 in the retracted position. Accordingly, nesting of the 
support arms 52 in the support arm recesses 57 increases the compacted 
storage of the system. 
With reference to FIG. 2, the basketball goal system comprises a bracket 
assembly 58 which connects to the backboard end 38 of the pole 34. In one 
presently preferred embodiment, the bracket assembly 58 comprises two 
members 60 which are pivotally connected to the pole 34 near the backboard 
end 38. Pivotal connection is achieved by a bracket pin 62 which is 
disposed on the bracket assembly 58 and through the pole 34 near the 
backboard end 38. The members 60 run generally parallel to the pole 34, on 
opposing sides of the pole 34, and form a channel 64. The channel 64 
receives the pole 34 when the basketball goal system is in the retracted 
position. 
A backboard 66 is connected to the bracket assembly 58. The backboard 66 
has a substantially flat faced front surface 68 and is configured to 
receive the impact of a basketball. The backboard 66 may be a conventional 
forty inch shatterproof plastic or fiberglass backboard. However, in one 
presently preferred embodiment, the backboard 66 is blowmolded from 
polyethylene and has a back surface 70 spaced apart from the front surface 
68 and a plurality of offsets 72 positioned between the back surface 70 
and front surface 68. The offsets 72 are defined by corresponding 
depressions in the back surface 70 such that each of the offsets 72 has a 
front end which is homogeneously secured to the front surface 68 and a 
back end which is homogeneously secured to the back surface 70. The front 
surface 68, back surface 70, and offsets 72 define an interior volume 74. 
The interior volume 74 is filled with a fill material principally formed 
of a significantly different material than the material of the front 
surface 68 and back surface 70. The fill material may be air, polyurethane 
foam, or another fill material. The backboard 66 of this embodiment is 
more fully detailed in U.S. Pat. No. 5,507,484 to van Nimwegen et al. and 
is incorporated herein by reference. 
In order to better support the backboard 66 the members 60, after running 
parallel to one another, diverge from one another at approximately equal 
and opposite angles. The backboard 66 and bracket assembly 58 pivot 
together about the backboard end 38 of the pole 34. The backboard 66 has a 
top portion 67 and a bottom portion 69. In the extended position, the top 
portion 67 is above the bottom portion 69 as is suitable for game play. In 
the extended position, the majority of the backboard 66 and bracket 
assembly 58 extends further distal from the base 12 than the backboard end 
38 of the pole 34. Accordingly, the majority of the backboard 66 and the 
bracket assembly 58 is above the backboard end 38 of the pole 34. Thus, in 
the extended position, the basketball goal system is at its maximum 
height. 
A bracket lock pin 76 is disposed on the bracket assembly 58 below the 
bracket pin 62 such that the bracket lock pin 76 is further distal from 
the backboard end 38 of the pole 34. The bracket lock pin 76 passes 
through a lock opening 78. The lock opening 78 is disposed near the 
backboard end 38 of the pole 34 to receive the bracket lock pin 76 when 
the backboard 66 and bracket assembly 58 are in the extended position. The 
bracket lock pin 76 secures the position of the bracket assembly 58 and 
the backboard 66 in the extended position. In the extended position, the 
backboard 66 is locked in a stationary position to permit rigorous game 
play. 
In a presently preferred embodiment the bracket lock pin 76 is a metal 
dowel having a head on one end and a spring loaded ball bearing on the 
opposing end. Force must be applied to the spring loaded ball bearing in 
order to insert or release the bracket lock pin 76 into or from the lock 
opening 78. In an alternative embodiment, the bracket lock pin 76 may be 
embodied as a threaded shaft with a head on one end and a threaded knob on 
the other for screwing onto the shaft. 
When the backboard 66 and bracket assembly 58 are in the retracted 
position, they generally remain in position due to gravity. In the 
retracted position, the bracket lock pin 76 dangles from the bracket 
assembly 58 or pole 34 by means of a lanyard, rope, or other suitable 
attachment. Attaching the bracket lock pin 76 to the rest of the system is 
to prevent loss of the pin 76 when the bracket lock pin 76 is not engaged 
in the lock opening 78. In alternative embodiments, an additional lock 
opening 78 may be disposed on the pole 34 for receiving the bracket lock 
pin 76 when the backboard 66 and bracket assembly 58 are in the retracted 
position. In this embodiment, engaging the bracket lock pin 76 in the 
additional lock opening secures the backboard 66 and bracket assembly 58 
in the retracted position. 
Also shown in FIG. 2 is a distal base handle 79. The distal base handle 79 
is used to secure the base 12 against a vertical surface in the retracted 
position as will be explained in greater detail below. 
A rim assembly 80 is pivotally connected to the front surface 68 backboard 
66. With reference to FIGS. 4A and 4B, one presently preferred embodiment 
of the rim assembly 80 is shown with the rim assembly 80 in the extended 
position. In the extended position, the rim 82 of the rim assembly 80 is 
generally perpendicular to the backboard 66 and horizontal to the ground 
surface. The rim assembly 80 further comprises a rim plate 84 which is 
connected to the rim 82. The rim plate 84 is connected to a rim mounting 
plate 86 at a generally perpendicular intersection 88. The rim mounting 
plate 86 is disposed parallel to the backboard 66 to support the rim 
assembly 80. The integrated connection of the rim plate 84 and the rim 
mounting plate 86 defines an "L" shaped member and are collectively 
referred to as the rim mount for the rim assembly 80. The perpendicular 
intersection 88 of the rim plate 84 and the rim mounting plate 86 allows 
mounting of the rim assembly 80 to the backboard 66 while supporting the 
rim 82 in the horizontal position. 
The rim assembly 80 is pivotally connected to the backboard 66 by a rim pin 
90 which is disposed through the rim assembly 80 approximately at the 
perpendicular intersection 88. A presently preferred embodiment for the 
rim pin 90 is a "U" bolt as shown best in FIG. 4A. The rim assembly 80 is 
configured with pivot slots 92 which allow the rim pin 86 access through 
the rim assembly 80. The pivot slots 92 are disposed at the perpendicular 
intersection 88 and extend partially into the rim plate 84 and rim 
mounting plate 86. The pivot slots 92 are configured with sufficient 
length to allow pivotal movement of the rim assembly 80 about the rim pin 
86. The rim pin 90, as embodied as a "U" bolt, passes through the 
backboard 66 and each pivot slot 92 to provide the pivotal connection. The 
ends 94 of the rim pin 90 extend through the back surface 70 of the 
backboard 66. 
The rim assembly 80 is also configured with pivot members 96 disposed 
adjacent to the perpendicular intersection 88 such that the pivot members 
96 contact the rim plate 84 and the rim mounting plate 86. Preferably, at 
least two pivot members 96 are used to provide adequate pivotal support, 
but an alternative embodiment could have one pivot member 96. The pivot 
members 96 receive the rim pin 90 as the rim pin 90 extends through the 
pivot slots 92. In one presently preferred embodiment, shown in FIGS. 4A 
and 4B, the pivot members 96 are washers. The washers 96 are disposed on 
the rim pin 90 and rotatably engage the rim plate 84 and the rim mounting 
plate 86. Preferably, the rim plate 84 and the rim mounting plate 86 are 
configured with depressions to receive the washers 96 and maintain the 
position of the washers 96. The pivot members 96 provide pivotal interface 
between the movable rim assembly 80 and the generally stationary rim pin 
90. As the rim assembly 80 pivots, the rim plate 84, rim mounting plate 
86, and perpendicular intersection 88 rolls across the pivot members 96. 
The pivot members 96 rotate when the rim assembly 80 is pivoted to 
facilitate movement of the rim assembly 80. The pivot members 96 must be 
of sufficient size and strength to resist breaking as they are subject to 
considerable tension during pivotal movement. 
In an alternative embodiment, the pivot members 96 are integrated with the 
rim plate 84, rim mounting plate 86, and perpendicular intersection 88 to 
form a unitary piece. In such an embodiment, the pivot members 96 move in 
conjunction with the rest of the rim assembly 80 instead of rotating 
separately. 
One of skill in the art will appreciate that the rim pin 90 may have 
various embodiments. For example, the rim pin 90 may comprise two "L" 
shaped bolts. Each "L" bolt would protrude out the back surface 70 of the 
backboard and act to pivotally connect the rim mount 84 and backboard 66 
in the same manner as the "U" bolt embodiment. Alternatively, two "U" 
bolts may be used to provide pivotal connection. In yet another 
embodiment, the rim pin may be configured as a "T" shaped bolt. In such an 
embodiment, a single pivot slot 92 would be required. Because the exact 
shape of the rim pin 90 is not critical to the teaching of the invention, 
other configurations for the rim pin 90 are possible and are included 
within the scope of the invention. 
In one presently preferred embodiment rim latches 98 are disposed on the 
backboard 66 as shown in FIGS. 4A and 4B to secure the rim assembly 80 in 
the extended position. Preferably, at least two rim latches 98 are used in 
order to better secure the rim assembly 80. The rim mounting plate 86 is 
configured with latch openings 100 for receiving the rim latches 98 in 
releasable engagement. The engagement of the rim latches 98 to the rim 
mounting plate 86 secures the rim assembly 80 into the extended position. 
This is necessary in order to maintain the horizontal position of the rim 
82 during rigorous game play. 
In one presently preferred embodiment, shown in FIGS. 4A and 4B, the rim 
latch 98 consists of a threaded knob which is manually fastened onto a 
respective screw protruding from the backboard 66. Thus, after a screw is 
received through a latch opening 100, the knob is fastened onto the screw 
and tightened until the rim assembly 80 is secured to the backboard 66. In 
an alternative embodiment, the rim latch 98 is a hook with a biasing 
device for directing the hook towards the backboard 66. In this 
embodiment, the latch opening 100 would receive the hook and then the hook 
would be adjusted to engage the rim mounting plate 86. The biasing device, 
such as a spring, prevents the hook from releasing the rim mounting plate 
86 during game play by forcing the rim mounting plate 86 towards the 
backboard 66. 
The rim assembly 80 further comprises biasing means 102 which are disposed 
on the rim pin 90. In one presently preferred embodiment, shown in FIGS. 
4A and 4B, the biasing means 102 comprises springs. The ends 94 of the rim 
pin 90 are threaded and are fitted with nuts 104 as the ends 94 protrude 
from the backboard 66. Alternatively, the rim pin 90 may be fitted with 
flanges on the ends 94. The springs 102 are disposed on the rim pin 90 
between the nuts 104 and the back surface 70 of the backboard thereby 
maintaining tension in the springs 102. 
The combination of the pivot members 96 and the springs 102 act as a detent 
to bias the rim assembly 80 in either the extended or retracted position. 
As the rim assembly 80 is pivoted about the perpendicular intersection 88, 
the pivot members 96 serve as a fulcrum and act to compress the springs 
102. When the rim assembly 80 is in the extended or retracted position, 
the pivot members 96 do not compress the springs 102. Thus, to move the 
rim assembly 80 from either the extended or retracted position requires an 
initial force to overcome the bias of the springs 102 and compress the 
springs 102. The pivot members 96 and springs 102 provide a spring action 
which will prevent the rim assembly 80 from remaining in between the 
extended or retracted position and will force the rim assembly 80 into one 
or the other position. Furthermore, during game play, the springs 102 act 
to provide a degree of vertical flexibility in the rim assembly 80 to ease 
the tension in the rim 82 and reduce the likelihood of breakage such as 
during a slamdunk. This is desirable because the rim 82 is often subject 
to vertical forces during game play. 
With reference to FIG. 5, a side view of the pivotal rotation of the rim 
assembly 80 from its extended position to its retracted position (shown in 
phantom) is shown. In the extended position for game play, the rim 82 
extends generally perpendicular to the backboard 66 and horizontal to the 
ground surface. To pivot the rim assembly 80 to the retracted position, 
the rim latches 98 are disengaged from the latch openings 100 in the rim 
mounting plate 86. Next an upward force is applied to the rim assembly 80 
to overcome the biasing means 102 and pivot the rim assembly 80 about the 
rim pin 90. At some point approximately midway between the extended 
position and the retracted position as the rim assembly 80 pivots towards 
the retracted position, the biasing means 102 acts to pull the rim 
assembly 80 into the retracted position. In the retracted position, the 
rim 82 is substantially parallel to the backboard 66 which reduces storage 
space for the basketball goal system. The rim assembly 80 may be pivoted 
back into the extended position by applying a downward force to overcome 
the biasing means 102. The rim assembly 80 is then made ready for game 
play by engaging the rim latches 98 through the latch openings 100 of the 
rim mounting plate 86. 
With reference to FIG. 6, a side view of backboard 66 and the bracket 
assembly 58 from its extended position to its retracted position (shown in 
phantom) is shown. The backboard 66 and the bracket assembly 58 remain 
secured together throughout a pivotal rotation about the backboard end 38 
of the pole 34. As shown, in the extended position the majority of the 
backboard 66 extends further distal from the base 12 than the backboard 
end 38 of the pole 34. Accordingly, the majority of the backboard 66 and 
the bracket assembly 58 extends above the backboard end 38 of the pole 34. 
Before rotating the backboard 66 and bracket assembly 58 to the retracted 
position, the locking bracket pin 76 is removed from the lock opening 78. 
At this point, the backboard 66 and bracket assembly 58 are free to pivot 
about the bracket pin 62. 
The backboard 66 and bracket assembly 58 are pivoted to the retracted 
position so that the top portion 67 of the backboard 66 is located below 
the bottom portion 69 of the backboard 66. As shown in phantom, the 
retracted position results in the majority of the backboard 66 and bracket 
assembly 58 extending further proximal to the base 12 than the backboard 
end 38 of the pole 34. Accordingly, the majority of the backboard 66 and 
bracket assembly 58 are below the backboard end 38 of the pole 34, thereby 
reducing the height of the basketball goal system. In the retracted 
position, the pole 34 is nested within the channel 64 formed by the 
members 60 of the bracket assembly 58. The force of gravity generally 
retains the backboard 66 and bracket assembly 58 in the extended position. 
Alternatively, the backboard 66 and bracket assembly 58 are secured in the 
retracted position by inserting the locking bracket pin 76 in an 
additional lock opening 78 disposed in a location corresponding to the 
retracted position. A reversal of these steps takes the backboard 66 and 
bracket assembly 58 from the retracted position to the extended position. 
With reference to FIG. 7, a diagram is shown illustrating manipulation of 
the basketball goal system from the extended position to the retracted 
position. As shown, the rim assembly 80 is pivoted into the retracted 
position so that the rim 82 generally runs parallel to the backboard 66. 
The system is directed toward vertical storage along a vertical surface 
106 such as a wall. Accordingly, in manipulating the basketball goal 
system into the retracted position, it is desirable to position the system 
along the vertical surface 106. As shown in FIG. 7 the system is pivoted 
about the proximal end 14 of the base 12 to place the entire weight of the 
system on the wheels 48. With the system in a tilted position the base 12 
is in a generally vertical position. The system is then maneuvered so that 
the base 12 is placed generally parallel against the vertical surface 106. 
FIG. 7 also shows a first retainer 108 which is utilized to ensure that the 
system remains in the vertical position against the vertical surface 106. 
The first retainer 108 is a strip of material which is preferably bendable 
such as metal, canvas, plastic or other suitable material. The first 
retainer 108 connects to the vertical surface 106 at one end, curves about 
the distal base handle 79, and connects to the vertical surface 106 at the 
other end. Connection of the first retainer 108 to the vertical surface 
106 may be done by fasteners such as bolts, screws, or adhesives. The 
retainer 108 prevents movement of the system from the vertical surface 106 
and prevents damage to the system as well as possible injury. With the 
system secured in this manner, further manipulation of the system is 
possible without risk of damage or injury. 
With reference to FIG. 8, further manipulation of the basketball goal 
system from the extended position to the retracted position is shown. The 
backboard 66 and bracket assembly 58 are pivoted from the extended 
position to the retracted position as explained previously above. The 
height of the pole 34 is reduced by disengaging the latch 44 from a 
corresponding depression 42 in the inner pole section 30 and telescoping 
the inner pole section 30 into the outer pole section 32. The height of 
the pole 34 is then secured by engaging the latch 44 with a depression 42 
corresponding to the lesser height. The collar fastener 56 is loosened 
thereby expanding the collar 54 and allowing pivotal movement of the pole 
34. The base 12 is vertically disposed against the vertical surface 106 
and the pole 34 is directed upward into the recess 18 of the base 12. As 
the pole 34 pivots upward, the collar 54 slides upward along the length of 
the pole 34. The support arms 52 follow the collar 54 upward until they 
extend in a vertical direction and partially nest in corresponding support 
arm recesses 57 in the base 12. Once the pole 34 is within the recess 18, 
the collar fastener 56 is tightened and the collar 54 constricted which 
secures the pole 34 in the retracted position. In this manner, the base 
12, pole 34, support arms 52, backboard 66, and rim 82 are all directed 
into a substantially vertical plane adjacent the vertical surface 106. 
With reference to FIG. 9, the basketball goal system is shown in the 
retracted position for compacted storage. The system rests on the proximal 
end 14 of the base 12 thereby reducing the amount of floor space for 
storage. The system stands approximately 8 feet in height allowing 
convenient storage in a garage or shed. The system is supported by the 
vertical surface 106 and the first retainer 108 to prevent tipping of the 
system. As shown in FIG. 9, a second retainer 110 is also utilized to 
further ensure that the system remains in the vertical position against 
the vertical surface 106. Like the first retainer 108, the second retainer 
110 is made of a material such as metal, canvas, plastic or other suitable 
material and is bendable. The second retainer 110 connects to the vertical 
surface 106 at one end, curves about the base 12 and pole 34, and connects 
to the vertical surface 106 at the other end. Preferably, the second 
retainer 110 curves about the base 12 close to the distal end 16 of the 
base 12. The second retainer 108 provides additional support to prevent 
movement of the system from the vertical surface 106. 
With reference to FIG. 10, a side view of the basketball goal system is 
shown in compacted storage against a vertical surface 106. As shown, the 
amount of floor space used by the system in a vertical disposition of the 
base is substantially reduced from a horizontal disposition of the base 
12. 
A reversal of the procedure outlined above takes the system from the 
retracted position to the extended position. 
The invention provides a ballast supported basketball goal system which is 
portable for storage without removing the ballast. The invention allows 
manipulation of the system to decrease the vertical height of the system 
and place the base 12, pole 34, support arms 52, backboard 66, and rim 82 
in a vertical plane thereby facilitating storage of the system in a garage 
or storage shed. The manipulation of the system from the extended position 
to the retracted position and visa versa is convenient and safe. 
Furthermore, because the components of the system remain largely connected 
to one another throughout the manipulation process, the opportunity for 
lost components is reduced. 
It will be appreciated that aspects of the present invention may be 
embodied in either portable or permanently installed basketball goal 
systems. For instance, the bracket assembly 58, backboard 66, and rim 
assembly 80 may be employed in either case. Furthermore, the base 12 may 
be permanently mounted on a track on a vertical support for upright 
storage. These aspects may be employed alone or in various combinations 
with one another. 
The invention may be embodied in other specific forms without departing 
from its spirit or essential characteristics. The described embodiments 
are to be considered in all respects only as illustrative and not 
restrictive. Any explanations provided herein of the scientific principles 
employed in the present invention are illustrative only. The scope of the 
invention is, therefore, indicated in the appended claims rather than by 
the foregoing description. All changes within the meaning and range of the 
claims are to be embraced within their scope.
