BACKGROUND

1. Field of the Invention

The present invention relates to method and apparatus for playing a ball game. More specifically, the present invention provides for an apparatus that enables players to engage in a fast-paced game that combines aspects of the games of volleyball and foursquare while providing a game frame that is portable and deployable in a variety of environments.

2. Description of the Related Art

There are several prior art variations of the traditional playground game of Four Square, but they share many of the same characteristics. Typically, the game is played with an elastic ball such as a rubber playground ball on a solid ground surface such as a concrete or asphalt playground or parking area. Referring to a top view of the prior art game square arrangement shown in FIG. 1A, a large square (10) is marked on a solid horizontal surface with a permanent medium such as paint, or with a temporary marking medium such as chalk. The large square (10) is approximately sixteen feet on each side (20) (or may be larger or smaller based on the skill of the players involved), and is further equally divided with orthogonal markings into four square interior play areas (A, B, C, and D).

Referring to FIG. 1A and FIG 1B, to begin play, four players (60) enter the large square (10) and each individual player (60) stands in one of the four interior play areas (A, B, C, or D). The player in interior square (or in the alternative, “box”) “D” is designated as the “server,” and places a foot in the small “service box” (40) within box D (or alternatively places a foot on the corner of the large square (10) nearest to the service box (40)) and begins a rally by hitting the ball (50) by hand into any one of the other boxes (A, B, or C). Optionally, game rules may require the server to allow the ball (50) to bounce once in the server's box (D) before it is struck by hand to enter another internal play box (A, B, or C), and in one variation, the ball must be served into the box diagonally opposite (B) of the server's box (D).

Once served, the ball enters one of the other internal play boxes (A, B, or C). It is allowed to bounce once, and then the player within the box that received the serve must strike the ball by hand, returning the ball so that it may bounce within another interior box before the ball bounces again. In one version of the game, a receiving player may hit the ball to another interior box before the ball bounces in that player's play box. The rally continues by players striking and returning the ball to other internal play boxes until a player is unable to successfully return the ball to bounce within another player's box.

The player that is unable to correctly return the ball to another square is considered “out,” and leaves the game square (10), optionally moving to the end of a queue of waiting players (30). If the server was not the “out” player, the server then receives one point toward that player's individual score, with an overall goal of remaining as server and accruing points as long as possible. After the “out” player leaves the game square (10), players rotate counterclockwise (from A to D) to fill in the gap of the missing “out” player, and then a new player enters into box A from the front of the player queue (30). In this arrangement, play continues indefinitely with players rotating through the game as players go “out,” and additional players may join by simply joining the end of the player queue (30).

Referring to FIG. 2, a court (200) for the classic game of volleyball is shown. Volleyball may be played in areas such as grassy lawns and beaches, since the game does not require a ball to bounce from a solid surface. However, the game requires that a net (220) be erected in a manner that prevents it from falling over after being touched, impact from ball strikes, or from natural events such as wind. Further, the outside boundaries of the volleyball court (210) must be clearly demarked to assist in determining when a ball that hits ground was within the boundary or out of bounds. Yet in play areas such as sandy-beaches, court boundaries (210) can be difficult to create in a manner that resists scuffing, player footsteps, and ball strikes. The erection of a temporary volleyball court on a soft play surface therefore presents challenges that delay players' abilities to quickly begin a game, and once the game is begun, boundaries (210) may have to be periodically redrawn.

What is needed, then, is a game that combines the excitement of volleyball with the rapid and fun game of four square. What is also needed is an apparatus that can be erected in a variety of playing environments without extended set up time. What is further needed is a gaming apparatus that is easily portable and breaks down to a size that lends itself to easy transportation and storage. What is further needed is a mechanism to create a foursquare-like game play area such as a beach or grass lawn that does not require a hard, completely flat surface with scuff-resistant edge indicia. What is further needed is an exciting, fast-paced interactive game that combines aspects of foursquare and volleyball, allowing for play on either hard or soft playing surfaces.

SUMMARY

In view of the foregoing, it is an object of the present invention to improve various problems associated with the prior art. More specifically, it is an object of the present invention to provide a portable game apparatus that enables players to perform a method of game play that combines aspects of volleyball and foursquare into a fun, exciting, multi-player game. To that end, the method and apparatus of the present invention provides a Four Square-like game that is played in the air above players' heads. By-providing for a portable, elevated game frame, player squares that are provided on a hard ground surface in Four Square are now elevated above the players' heads, and a player now uses volleyball-like ball strikes to hit the ball up and out of the players' game square and into another player's game square. Alternatively, the present invention may be viewed as a 4-way volleyball game without the need for nets or markings on the ground.

Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

FIG. 3 illustrates an overall conceptual view of one embodiment of the apparatus of the present invention, herein also referred to as the “game frame” (300). In one embodiment, the game frame (300) can be used as a game apparatus to play a game in which a projectile is projected among players. It is understood by those of skill in the art that such projectiles may constitute any number of objects that are adapted to play a game, such as a ball, a shuttlecock or “birdie,” a balloon, a beanbag, or a self-illuminated object. The game apparatus has at least three substantially equal volumes. Each volume is contiguous with each other volume and is sized sufficiently to be occupied by at least one player. Each volume is also bounded or otherwise defined by a plurality of elongate members that are above a playing surface. By way of example, and not by way of limitation, each or some of the elongate members can be a pole. At least some of the elongate members are positioned above the heads of the players. In the game, players project the projectile over the elongate members that are above the heads of the players. In one embodiment, the game apparatus also has means for connecting each elongate member so as to be substantially normal to at least one other elongate member. In an alternate embodiment, elongate members may be comprised of inflatable elastomeric members that assume a substantially rigid shape upon inflation. Also, the game apparatus has means, for at least some of the elongate members, for adjusting the length of the elongate member, and in an inflatable embodiment, the means for adjusting the length may comprise inflation or deflation. Each elongate member can be made of aluminum, steel, PVC, vinyl, polystyrene, polyethylene, nylon, or combinations thereof.

Each said volume has a three dimensional (3D) shape. The 3D shape is defined by the linear movement of a 2D object, such as a rectangle, a circle, an octagon, a triangle, or a polygon. Thus, a linearly moved square (2D) forms a volume that is a cube (3D).

The adjustment means can be one or more joints for moving the elongate member between an open and a closed position thereof. The closed position, for instance, can be a pole that is folded in half. The joint can be hinge or a bending member formed in the middle of the pole. The adjustment means can be capable of allowing the pole to be disassembled. Also, when a pole is made up of substantially concentric poles, the adjusting means can be for telescoping an inner pole within an outer pole. Also in the inflatable embodiment, the adjustment means may comprise inflation or deflation of an inflatable pole.

For each volume, the connecting means and adjusting means respectively articulate to collapse the volume such that the plurality of elongate members thereof are parallel one to another. Also, the connecting means and adjusting means respectively articulate such that the plurality of elongate members can be moved into an operative position in which each elongate member is substantially normal to at least one other said elongate member, and a collapsed position in which each said elongate member is substantially parallel to each other said elongate member. Examples of the foregoing, for one embodiment, are seen in FIGS. 7-10. In an alternate embodiment, the game frame (300) is allowed to be deployed through inflation from a substantially collapsed position to an operative position, and through deflation, the deployed game frame (300) may be collapsed.

Each volume will preferably have a width and height suitable for the players. For instance, adults would prefer a width not less than four feet and a height not less than six feet.

In yet another embodiment, the game frame (300) is comprised of horizontal bar members (350) substantially parallel to a ground or play surface interconnected to form an orthogonally-bisected square defining the top of four interior play boxes (A′, B′, C′, and D′) with one connection point (360) common to all four interior play boxes (A′, B′, C′, and D′). While one embodiment illustrated in FIGS. 3 and 4 is substantially symmetrical with respect to a vertical axis, other embodiments may be comprised of asymmetrical collections of volumes (or play boxes).

The twice bisected square that defines the top of the game frame (300) is supported above the ground or play surface by four vertical corner poles (310), four mid-poles (320), and a center pole (330). The poles, together with the bar members and the bottom play surface, define a polyhedron-like shape, which further comprises the interior polyhedron volumes or play boxes (A′, B′, C′, and D′) that are occupied by players. The volumes defined by the interior play boxes (A′, B′, C′, and D′) may be contiguous or substantially contiguous, and one player is intended to occupy each volume. Each top side of an interior play box (A′, B′, C′, and D′) is comprised of two substantially horizontal bar members (350) hingedly or detachably connected at their midpoints by articulation points (340) comprised in one embodiment of locking bar hinges. In alternate embodiments, the articulation points are comprised of flexible bending points, friction-fit connections, double pin hinges, or snap-fit connections. In an alternate embodiment, each top side (A′, B′, C′, and D′) of the interior play boxes is not defined by two hingedly interconnected bar members, but a single rigid bar member, and in additional embodiments, the bar members (350) may further comprise two or more articulation points (350) for enhanced disassembly. In yet another embodiment, the game frame (300) is comprised substantially of inflatable elastomeric structural members, that deploy from a flaccid, portable collapsed shape, to a rigid or semi-rigid structure upon inflation. In such inflatable embodiment, bar members (350) and poles (310, 320, 330) may be permanently or detachably affixed to form the game frame (300). By operating a valve that is integrated with such bar members (350) or poles (310, 320, 330), the user may allow for deflation and subsequent storage of the game frame (300) in a substantially compressed condition.

The bar members (350) that do not reside on the outside edge of the game frame (300) not only serve to add structural integrity to the game frame (300) but also provide a barrier over which a projectile (50) (for instance, a ball, a birdie, or another object) must pass during play, much as a volleyball must pass over a net. The projectile may be projected by a player simply by throwing, kicking, punching, or hitting it, or by a player hitting the projective by a bat, a racket, a stick, a paddle, or another instrument. Preferably, the projectile is a ball that is manually projected by the players among themselves over the barrier and into each respective player's play box or volume.

Each interior play box is further comprised of one outside corner (370), two mid-corner proximal connections (380) and a connection (360) proximal to the center pole (330). While in one embodiment the poles (310, 320, 330) may be rigid and incapable of folding, in an alternate embodiment, the poles (310, 320, 330) further comprise a take-down element (345) whereby the poles may be shortened in length through a flexible bending point, a locking hinge-fold mechanism, or through a concentric inner pole element capable of telescoping into and out of a hollow outer element of the pole. While bar members (350) may be permanently connected to poles (310, 320, 330), in one embodiment, bar members (350) are attached to the poles (310, 320, 330) through a friction fit socket, or in another embodiment, bar members (350) attach at outside corners (370), central T-junctions (380) and the central four-way junction (360) through hingedly-movable connections. Takedown and disassembly of the game frame is discussed in more detail below.

In one embodiment, poles (310, 320, 330) and bar members (350) may be manufactured from tubular steel, aluminum, PVC, polystyrene, polyethylene, nylon, vinyl, or any substance that is sufficiently lightweight to be person-portable yet rigid enough to be self-supporting and resistant to bend forces induced by ball or player strikes. In an alternate embodiment, poles (310, 320, 330) and bar members (350) may be manufactured from transparent material, wherein light strings such as miniature Christmas-type bulbs or LED lights are contained within the poles and bar members to light the structure and alternatively to provide ambient light for night-time play or decoration. Alternatively, the poles and bar member may be manufactured from either semi-transparent or partially transparent material, and string lights are molded into a channel within each frame member. In another embodiment, poles and bar members further comprise channels substantially aligned with the central axis of the poles and bar members, wherein LED lights and wiring strings are retained within the channel by a friction fit, a set of clamps, or conventional adhesives. In an alternate embodiment, the lighting system further comprises an electronic control unit that provides a pulsed signal to the lights, so that various patterns of flashing and/or multicolor display may be achieved, such as provided by prior art synchronous Christmas “chaser” lights.

Referring to FIG. 5, the shape of the game frame (300) need not be limited to twice-bisected square or rectangular polyhedrons. Rather, many embodiments are possible whereby an arrangement (300A) of poles (510) and bars (500) define contiguous or substantially contiguous interior volume spaces that provide sufficient room for players to move and return projectiles over the top bar members of the game frame to other game boxes. Plan views of the top surface of exemplary embodiments are shown in FIG. 6, and comprise a square bisected at its vertices rather than midpoints (610), a twice-bisected circle (620), an octagon crossed with bars at its vertices (630), a rectangle defining a plurality of interior game spaces, such as six spaces (640), and a triangle (650) defining three interior game box spaces. In most cases, poles will attach to each vertex created by the intersection of the bar members and shapes shown on FIG. 6. The three-dimensional shapes formed by a hypothetical outside implied surfaces stretched along such top surfaces and poles could be a rectanguloid, cylinder, extruded octagon, extended rectanguloid, or extruded triangle, respectively.

In one embodiment of the game frame illustrated in FIG. 3, the length of the poles (310) is approximately seven feet, and each interior game box (A′, B′, C′, and D′) measures eight feet on each horizontal side, making the overall outer dimensions of the polyhedron defined by the game frame approximately 16 feet by 16 feet by seven feet high. While this embodiment provides for one play configuration, other dimensions may be easily provided for, such as if the poles (310) were decreased in length to allow an embodiment that was easier to play for short children. In one embodiment, in a manner similar to camera tripod legs, the poles (310) may be shortened to a desired play length through a telescoping action provided by pole take-down elements (345). Those of skill in the art also may recognize that the dimensions of the interior game boxes may be varied from the exemplary eight feet by eight feet to accommodate available play space or differing players' ability.

In one embodiment, the projectile (FIG. 4, 50) may be a rubber playground ball, or may be a typical play ball found in most toy sections of stores, such as balls with approximately ten-inch diameters and weighing approximately 95 grams. Alternatively volleyballs may be utilized as the game ball (50), and if the outside environment is being subjected to significant wind, a partially-deflated volleyball can offset the wind-induced shear forces, allowing for more enjoyable play. Generally, lighter balls provide for longer rallies and are better adapted to players of lower ability, while heavier balls provide more challenge and are more resistant to wind effects.

Turning now to FIGS. 7, 8, 9, and 10, the game frame apparatus (300) in FIG. 3 will now be shown in various stages of disassembly. In FIG. 7, downward force (700) is applied to the articulation points (340) so as to hingedly bias bar members (350) downward as shown in the arrows (700). As the bar members (350) rotate downward, the game frame (300) collapses inwardly in an accordion-like manner (710). Once the game frame (300) has collapsed inwardly, (FIGS. 8, 9, 10, items 801, 901 and 951, respectively) the bar members (350) and poles (310, 320, 330) come into close proximity in a bundle that eases transportation of the game frame. In one embodiment, to further shorten the bundle of rods and poles to improve portability, poles (shown as 310, but may also comprise poles 320 or 330) may be further folded (FIG. 8, 802) by rotating a bottom section of poles through a hinged joint (FIG. 8, 345). In an alternate embodiment (902) shown in FIG. 9, bottom sections of poles (310, 320, 330) slide in a telescoping manner (900) into larger upper chambers through an aperture to a larger outer top tube (345), which in outer deployed position could have been fixed by a clamp, rotating friction collar, set screw, or pin. In yet another embodiment (952) shown in FIG. 10, bottom sections of poles (310, 320, 330) detach from the top sections of the poles, and while held together with elastic or stretchable lines (345) are capable of being folded vertically to join the bundle of bar members and poles (952), in a manner not unlike many disassemblable tent support poles in modern backpacking tents. As a result, the fully disassembled game frame (300) forms a dense and readily transportable bundle (803, 903, 953) that may be slid within a tote bag or carry box.

In an alternate embodiment, the articulation points (340) on the top surface of the game frame (300) do not hingedly connect; rather, bar members (350) separate at the articulation points (340) through fastening means such as friction fit or pin-fastened connections, and then bar members (350) are free to rotate downward through hinged communication with corner junctions (360, 370, 380), and each pole (310, 320, 330) separates from the game frame with either two, three, or four bar members (350) hingedly attached.

Referring to the apparatus shown in FIG. 4, the method of game play is now described. Initially, four players stand individually in play boxes (A′, B′, C′, and D′). The player (460) that stands in the D′ box (the serving box or volume) is identified as the serving player, and touches one foot to the outside corner pole (410). The rally begins with other non-serving players (465) standing in their respective play boxes and awaiting the serve. The serving player (460) either strikes or pushes the ball (50) with a volleyball-like hand motion up and out of the serving box so that the ball (50) lands in one of the other players' (465) boxes (A′, B,′ or C′, or the “nonserving” boxes). The player (465) that receives the served ball must return it up and out of their box and down into another player's box. The rally continues until a player (460 or 465) allows the ball to touch the bottom play surface (420) inside or outside of the game frame (300) without successfully returning it over the top of a bar member into another player's box. That player is then “out,” must exit the game frame, and return to the end of the queue (30) of people (60) waiting to enter box A′. Without passing the D′ box, the other players then rotate counter-clockwise to fill in the volume or play box that was vacated by the “out” player, and then the person at the front of the queue (30) enters box A′, thus causing all play boxes (A′, B′, C′, and D′) to be occupied by a player. Once a player rotates into play box D′, that player becomes the new serving player and receives a point each time a rally ends where another non-serving player (465) is “out.” The first player to receive ten points wins the game, and a new game may then be started.

In one embodiment of the method of the present invention, the serving player (460) should observe the following rules when serving: (a) one of the serving player's feet should be in contact with the outside corner pole (410), (b) the serving player (460) should annunciate that player's current score aloud before serving, and (c) the serving player (460) should serve the ball into another player's (465) box (A′, B,′ or C′) without the ball (50) touching any of the game frame's horizontal bar members (or barriers) as shown by the two exemplary bar members (350) in FIG.4. If the serving player (460) fails to observe the aforementioned rules, the serving player is considered “out” and must leave the serving player box (D′). Rotation and new player entry then occurs as described above. During the course of a rally, it is permissible for the ball (50) to deflect off of any number of horizontal bar members (350) as long as it ultimately comes down inside of some other player's box.

Although an exemplary, preferred embodiment of this invention has been described using preferred commercial products, it will be readily understood by those skilled in the art that modifications of the methods and apparatuses described, as well as substitution of equivalent commercially available products may be made without departure from the spirit and scope of the invention claimed.
