with reference to fig1 through 3 , there are shown front , side and plan views of a sport facility 10 in accordance with a first embodiment of this invention . as illustrated , the sport facility 10 is equipped with a pair of regulation basketball rims 12 and backboards 14 for playing a modified version of basketball . however , the benefits and competitive enjoyment of the game made possible by the sport facility 10 of this invention could be realized with rims and backboards other than those shown , in order to accommodate young children and other conditions which might affect the ability of individuals to participate and use the sport facility 10 . the sport facility 10 includes a playing area which is generally defined by a playing surface 16 . if the sport facility 10 is intended to be a permanent installation , the playing surface 16 can be formed with asphalt , concrete or any other suitably hard and durable material . alternatively , the sport facility 10 can be configured to be supported on a mobile platform to enable the sport facility 10 to be transported , as represented by a second embodiment of this invention shown in fig4 . because the sport facility 10 incorporates water into the activities in the playing area , the playing surface 16 preferably has a slight incline to ensure the proper drainage of water . furthermore , as most readily seen in fig2 a drain 36 is provided through which water can escape from the playing area . as illustrated in fig1 through 3 , the playing area is composed of two juxtaposed courts 20a and 20b on which two individuals or teams can compete against each other . however , it is foreseeable that a single court or more than two courts could be provided within the same sport facility 10 to allow an individual or team to compete against a clock , or to allow simultaneous competition among several individuals or teams . the outer periphery of the playing area can be delineated by any suitable structure , such as the rails 18 shown , though other structures could be used , including a mesh which assists in keeping a ball in play within the playing area . the shape and size of the playing area are generally unimportant , and can be adapted to suit the particular needs of the circumstances . with the two court version shown in the figures , the sport facility 10 has a rectangular shape which is partitioned with a center divider 22 . as shown in fig2 the center divider 22 is composed of a center railing 24 over which a protective padding 26 is placed . the protective padding 26 can be formed of any suitable material , such as a lightweight rigid foam polyvinyl chloride . enclosed within the protective padding 26 and supported by the center railing 24 is a water spray system , composed of a supply line 38 which receives water under pressure from a suitable source ( not shown ). the supply line 38 supplies pressurized water to a number of spray heads 40 mounted within apertures 42 formed in the protective padding 26 . each spray head 40 may include a pair of nozzles , each of which points to a different court 20a or 20b and is supplied with its own supply line 38 . alternatively , a single nozzle could be used , and selectively pointed with a motor ( not shown ) toward either court 20a or 20b depending on the circumstances . the number and type of spray heads 40 may vary , but each with the preferred result of forming spray patterns 44 which cover essentially the entire playing surface 16 , as illustrated in fig3 . this can be achieved with spray heads 40 which broadcast a spray of water in an arcuate horizontal band , or with spray heads which oscillate and emit water in a more compact stream . in accordance with the two court configuration shown in the figures , a backboard 14 and rim 12 are provided in each court 20a and 20b . each rim 12 is conventionally provided with a net 46 . as noted above , the backboards 14 and rims 12 can be sized and positioned at a height of ten feet above the playing surface 16 in accordance with basketball regulations . the backboards 14 and rims 12 are supported at adjacent ends of each court 20a and 20b above the playing surface 16 by a pair of cross arms 28 mounted to a pair of uprights 30 . in order to provide proper support for the uprights 30 , a concrete base 32 is preferably provided for each upright 30 , as would be conventional for such purposes . preferably , anchor bolts 34 are embedded in each concrete base 32 to which the base of the uprights 30 can be secured . provided with each net 46 is a sensor 48 which is capable of detecting when a ball passes through the rim 12 . the sensor 48 is shown schematically in the figures as a band which encircles the net 46 . the type of sensor 48 is generally unimportant , as long as a suitable signal can be generated each time a goal is scored . motion sensors of the type known to those skilled in the art provide a relatively low cost sensing unit , and can provide a suitable output at low operating voltages . however , it is entirely foreseeable that other types of sensors and transducers could also be adapted by one skilled in the art to record goals scored during the use of the sport facility 10 of this invention . finally , a control system 50 is provided which communicates with the sensor 48 and regulates the flow of water through the supply line 38 and is used to initiate the flow of water through the spray heads 40 . the control system 50 is preferably programmable in order to allow the type and duration of play to be altered as desired . a suitable unit for such purposes is an slc500 series programmer available from allen bradley , though numerous other programmers could be used . the control system 50 communicates with the sensor 48 through appropriate wiring 52 which , as shown , is preferably concealed below the playing surface 16 and within the uprights 30 and cross arms 28 . control of flow to the spray heads 40 can be achieved with a solenoid , represented schematically by reference number 54 . the control system 50 and the solenoid 54 are both preferably enclosed within a suitable enclosure 56 . because the sport facility 10 of this invention is particularly ideal for use on a play - for - pay basis , a vending unit 58 can also be installed within the enclosure 56 . in use , the control system 50 is programmed to initiate the flow of water to the spray heads 40 upon receiving an appropriate signal , or an appropriate number of signals , from the sensor 48 . for example , the control system 50 can be programmed to penalize one or more players in one of the courts 20a and 20b by spraying the court 20a or 20b with the lower score when a predetermined number of goals are scored in the higher scoring court 20a or 20b . for instance , if the player or players on court 20a have scored three goals before the player or players on court 20b , the control system 50 can direct flow to the spray heads 40 pointed at the court 20b to deliver a spray of water in accordance with the spray patterns 44 shown in fig3 . alternatively , both courts 20a and 20b can be subjected to a water spray if a predetermined number of goals are not scored in an allotted period of time . obviously , various other criteria can be used to determine when and which court 20a or 20b is to be subjected to the water spray . fig4 illustrates a variation of the sport facility 10 shown in fig1 through 3 . essentially , fig4 shows a sport facility 110 which can be operated in an identical manner to that shown in fig1 through 3 , but utilizes a mobile platform to allow the sport facility 110 to be relocated as desired . for clarity , the same reference numbers cited in fig1 through 3 are repeated here for the same components . as shown , the sport facility 110 is supported on a chassis 60 equipped with wheels 62 . the sport facility 110 generally is configured to have a pair of wing units 64a and 64b which can be folded over a central unit 64c located directly over the chassis 60 . the wing units 64a and 64b are attached to the central unit 64c at a corresponding pair of hinged joints 66 . when fully expanded to permit play , the wing units 64a and 64b are preferably supported above the ground with adjustable jacks 68 , as shown . additional jacks 70 can also be placed beneath the chassis 60 to provide additional support and stability to the sport facility 110 . to provide additional support and stability to the uprights 30 supporting the rim 12 and backboard 14 , a brace 72 preferably interconnects the uprights 30 with the railing 18 . in a preferred embodiment , the brace 72 is a cylinder which allows the uprights 30 to be rotated about a joint 74 and retracted over the playing surface 16 to facilitate transport of the sport facility 110 . again , this embodiment is intended to enhance versatility , and need not affect the play of the game . from the above , it can be seen that a significant advantage of the sport facilities 10 and 110 of the present invention is that the competitiveness of a game of basketball is increased due to the potential for one player or group of players to be penalized at the conclusion of the game . for a basketball game which ends upon a certain number of goals being scored , the spray of water can occur quite unexpectedly , though tension continues to increase as time passes and each player is aware that the end of the game is drawing near . though the water spray serves as a way of punishing the loser , it does so in a manner that can be enjoyed by all participants , both winners and losers alike . as with other recreational water activities , the water spray can also be particularly refreshing if played outdoors on a hot day . another significant advantage of the present invention is that additional enjoyment is also created for spectators of the game . with heightened enthusiasm of a crowd , the enjoyment of playing the game increases for the players as well . overall , the sport facilities 10 and 110 of this invention offer an appealing activity that is suitable for amusement parks , and combines the competitive appeal of basketball with the refreshment and appeal of a recreational water sport . in addition , the advantages of the sports facilities 10 and 110 can be realized by equipping a pre - existing basketball court with the sensor 48 , spray system and control system 50 of this invention . accordingly , this invention can potentially be installed at numerous locations without necessitating an investment in a court , backboard and rim . in summary , the present invention provides a sport facility for playing a modified version of basketball , in which a system is included for penalizing the performance of a player or team in a manner which encourages the competitiveness of the game and the enjoyment by spectators . this combination can have minimal effect on the conditions and equipment with which a basketball game is played , while significantly affecting the competitiveness inherent with the game of basketball . the sport facilities 10 and 110 of this invention promote a positive and significant impact on the competitiveness of the game , allow viewing by numerous spectators , such as at an amusement park , and enhance the enjoyment of the game &# 39 ; s spectators , such that the overall competitiveness of the game is further enhanced by the response and enthusiasm of the crowd . while the invention has been described in terms of a preferred embodiment , it is apparent that other forms could be adopted by one skilled in the art . for example , the geometry of the playing area could differ substantially from the rectangular - shaped area shown in the figures , the physical structure of the sport facilities 10 and 110 could be modified considerably , and various components and equipment could be used to modify or supplement those described from the sensing , control and water spray systems . accordingly , the scope of the invention is to be limited only by the following claims .
a sport facility and equipment for playing a game with a ball , in which the overall physical conditions of the game are similar to basketball . the facility is configured to use a basketball or a ball of similar size , in which the object of the game is to throw the ball through a hoop and thereby score a goal . the facility and equipment further include a system for penalizing the performance of a player or team in a manner which encourages the competitiveness of the game and the enjoyment by spectators . specifically , a system is used to keep track of scores made by one or more participants playing in one or more playing areas . using preselected criteria , the losing team is doused with a spray of water at the completion of a game .
