 This invention relates generally to enclosed or stand-alone play areas in which children can engage in various ball throwing activities, and activity centers for use in the play area.
 Enclosed play areas have become vary popular. For example, many fast food restaurants include enclosed play areas adjacent to their eating areas. Such play areas however, are generally limited to climbing equipment, slides, ball pits, etc. Additionally, because of the size of the elements or components of such play areas, they are typically used by small children (i.e., younger than about 4-8 years old). Similar play areas are used in community centers, family entertainment centers, and other places where it is desirable to have enclosed play areas. However, as noted, the enclosed play areas are generally limited to slides, ball pits, etc.
 To increase the range of activities available to children in enclosed or standalone play areas, the present invention provides an enclosed activity area which is directed mainly to ball throwing activities. Because the enclosed play area avoids the slides, climbing elements, and ball pits typical of currently enclosed or indoor play areas, the enclosed play area of the current invention will be appealing to older and larger children, and even adults.
 The enclosed play area comprises a front wall, a back wall, side walls, and a ceiling which define an enclosed area. The front, back, and side walls, and the ceiling are formed from intersecting frame members which define areas having a geometric shape. One or more activity stations are mounted to the frame members in the enclosure. Each activity station comprises at least one tub in which one or more hoops are mounted, the hoops being sized to allow a ball to be thrown through the hoops. The tub has a rim defining a mouth, wall surfaces extending rearwardly from the rim, and a back. The rim has a geometric shape corresponding to the geometric shape of the area defined by the frame members. The tub is mounted to the frame members such that the mouth of the tub is generally flush with an inner surface of the wall or ceiling to which the tub is mounted. Preferably, the front, back, and side walls, and the ceiling are covered by a transparent material, such as a mesh, fencing, or a plastic barrier. Preferably, the material is one which cannot be climbed easily by children.
 The activity stations can take on many different configurations, and are essentially limited by size and space. In one example, the hoop is a multi-hoop having a horizontal hoop and a plurality of diagonal hoops extending from said horizontal hoop. The diagonal hoops are spaced about the horizontal hoop and connected to adjacent diagonal hoops. The diagonal hoops can extend either upwardly or downwardly from the horizontal hoop.
 In another example, the hoop can be a multi-hoop having two hoops—a horizontal hoop and a vertical hoop which is generally perpendicular to the horizontal hoop.
 The activity station can be provided with panels positioned above and below the tub. The panels are provided with a port, and the ports of the two panels are connected via one or more tubes through which a ball can pass.
 The activity station can also include two or more hoops mounted in the tub, with the hoops being spaced vertically and/or horizontally from each other. To space the hoops both vertically and horizontally from each other, the top wall of the tub can be stepped to define a forward portion and a rear portion of the top wall, with the top wall rear portion being lower than the top wall upper portion. A first hoop is mounted to the top wall forward portion and a second hoop mounted to the top wall rear portion, with the hoops being generally parallel to each other. A third hoop can also be mounted to the tub back wall. The third hoop is preferably spaced rearwardly of and below the second hoop. The third hoop can be a multi-rim hoop and comprises a horizontal rim and a vertical rim.
 The activity station can also comprise two tubs. Tubes extend between the tub ports and place the tubs in communication with each other. One of the tubs is also preferably provided with a hoop. The hoop (which can be a single or multi-rim hoop) is mounted to a wall of the tub opposite the port in said tub. The tube is oriented, and said hoop is positioned, such that a ball exiting said tube will can pass through the hoop.
 In another variation of the activity station, the activity station can comprise a panel mounted to the front of the tub. The panel includes a bottom edge spaced from a bottom of the tub rim and at least one (and preferably two or more) opening in the panel. Further, the openings preferably have two or more shapes—for example, the openings can be circular, square, or diamond shaped. The panel openings are sized to allow a ball to pass therethrough. The distance between the panel bottom and the tub bottom defines a gap sized to allow the ball to pass therethrough. Further, the shape of the tub causes the ball to return (i.e., pass back out through the gap) when a ball passes through one of the openings.
 Corresponding reference numerals will be used throughout the several figures of the drawings.
 The following detailed description illustrates the invention by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what I presently believe is the best mode of carrying out the invention. Additionally, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

 As can be appreciated, the enclosed play area is centered around ball throwing activity stations. The size of the play area can be increased or decreased as desired. The number, arrangement, and position of activity stations which are mounted in the play area can also vary. For example, one or more of the activity stations can be excluded from a play area. More than one of any of the activity stations can also be included in a play area. The position of the activity stations on walls can be changed depending on the age group of children which will use the play area. For example, the height of the activity stations can be lowered for smaller children and raised for older children. Alternatively, a single play area can have activity stations that are of varying heights to accommodate children of different size and skill levels. Further, other activity stations, not disclosed herein, can be included in the play area without departing from the scope of the invention. For example, hoops can be mounted on the tub side walls. The tubs of different activity stations can be interconnected via tubes to, in effect, combine different activity stations. Additionally, the play area is not intended to be limited to the activity stations shown and described above. In fact, the play area can include various other types of backboards and activity stations, including activity stations which are not centered or built around the tub. Preferably, the hoops (and balls) are smaller than standard basket ball hoops and balls. However, the hoops and balls used in the play area can be made to most any desired size.
 Further, the rims of the tubs for the various activity stations are all the same size. Hence, the activity stations are modular, and the modular activity stations can be removed from the play enclosure for repair or replacement. Additionally, one modular activity station can be replaced with a new activity station, or the arrangement of the modular activity stations can be rearranged, if desired. As can be appreciated, the use of modular activity stations gives the designer and operator of the play area a significant amount of freedom in the placement of activity stations in the play area. Additionally, older activity stations can be replaced with newer activity stations (which may or may not be the same as the older activity stations) with very little down time in the operation of the play area.
 As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. For example, the frame members of the play area walls are shown to define square areas, and the tubs are all based on a square rim. However, the tubs could be based on a rim which is, for example, triangular, pentagonal, hexagonal, etc. The frame members would then similarly intersect to form correspondingly shaped areas in which the tubs can be mounted. Although the invention is described with respect to an enclosed play area, it will be apparent that the tubs or activity stations can be mounted to a single wall (or an overhead ceiling), and not be part of an enclosed play area. These examples are merely illustrative.
