DETAILED DESCRIPTION
This disclosure is directed to a portable miniature golf game in which the playing surface and game components are scaled to be used on a tabletop or similarly sized area. Moreover, unlike a traditional miniature golf course wherein each course or hole is permanently arranged so that it takes up valuable space even when not in play, the game components of the disclosed apparatus are reconfigurably arranged on the playing surface, so different courses or holes can be constructed serially on a single playing surface, thereby leading to very efficient use of space. Moreover, the game components may be arranged and rearranged in nearly unlimited manners on the playing surface to construct new courses, thereby allowing the players to impose new, surprising, and fun challenges with each construction.
FIG. 1 shows game apparatus 10 arranged during an exemplary game. Apparatus 10 includes a flexible rectangular playing surface 12 bounded by raised opposite first and second end rails 14 and raised opposite first and second side rails 16. One or more players constructs a course or “hole” on playing surface 12 by arranging a selected set of variously shaped course components, including tee zone 18, ball receptacle 20, large arch 22a, small arch 22b, semi-circle 24, corners 26, bridge 28, long rails 30, medium rails 32, and tall pegs 34. Other available course construction components shown in FIG. 2 include stream 36, ramps 38, short rails 40 and short pegs 42. Once selected the game components 18-42 are arranged on playing surface 12, one or more players uses a mallet 44 to maneuver the player's ball 46 from tee zone 18 to ball receptacle 20.
As shown in FIG. 3, in an exemplary embodiment, playing surface 12 is provided with its first and second opposite end edges 13 attached to end rails 14 (such as by the use of adhesive or mechanical fasteners, for example). As shown in FIG. 2, playing surface 12 is rolled about one of the end rails 14 for a compact presentation for storage or transport. Each end rail 14 includes dowel pins 48 disposed proximate opposite ends of the end rail 14 that align with bores 50 in opposite ends of side rails 16. After unrolling playing surface 12, side rails 16 are removably attached proximate first and second opposite side edges 15 of playing surface 12 by inserting dowel pins 48 into bores 50 in each end of each side rail 16. While one suitable construction is shown and described, it is to be understood that the mechanical parts may be otherwise provided; for example, pins may be positioned on side rails 16 and complementary bores on end rails 14. Moreover, other temporary attachment mechanisms known in the art may also be used, such as hook and loop fasteners, latches, dovetail and other common joints, and magnets, for example.
In an exemplary embodiment, playing surface 12 has sufficient elasticity to allow for such assembly while presenting a smooth playing surface 12 once assembled. In an exemplary embodiment, playing surface 12 is constructed from a mat material in green to resemble a grass surface. One such material, for example, is available from RPM, Inc. of Savage, Minn. under the trademark DRYMATE®. Desirable properties of playing surface 12 include durability, edges that do not fray, flexibility for rolling, and the propensity to lay flat after being rolled or folded for an extensive period of time, for example.
Once assembled as shown in FIG. 3, end rails 14 and side rails 16 form a raised perimeter border that surrounds rectangular playing surface 12. Because end edges 13 of playing surface 12 are permanently attached to end rails 14, when assembled, playing surface does not slip or shift with respect to the border formed by end rails 14 and side rails 16. In an exemplary embodiment, end rails 14, side rails 16, tee zone 18, ball receptacle 20, large arch 22a, small arch 22b, semi-circle 24, corners 26, bridge 28, long rails 30, medium rails 32, tall pegs 34, ramps 38, short rails 40, short pegs 42, mallets 44 and balls 46 are constructed of wood or similar material.
In an exemplary embodiment, no fastening mechanism is required between the course construction elements 18-42 and playing surface 12. In such an embodiment, each of the course construction elements is of sufficient weight and has a suitable surface to be retained upon playing surface 12 so as to not be dislodged by the action of balls 46 against the course construction elements 18-42. In one embodiment, an anti-slip coating may be provided on a surface of each of the course construction elements 18-42.
In an exemplary embodiment, tee zone 18 includes a plurality of spaced depressions 52 in which a ball 46 may rest for initial placement at the beginning of play. Ball receptacle 20 includes an inclined upper surface 54 and a relatively large and deep hole 56 into which a ball 46 may drop and be retained. Each of balls 46 may be differently colored or patterned or may be otherwise be visually differentiable so that each player can easily identify and track his or her own ball. Stream 36 simulates a water hazard; it has a curvilinear shape with an elongated central valley 60 surrounded by an inclined rim 58.
Large arch 22a, small arch 22b, semicircle 24 and corners 26 are sized in an exemplary embodiment with complementary curves so that they can be formed from a rectangular piece of material, as shown in FIG. 2. Specifically, each of two corners 26 has a quarter-circle cut-out 62 sized to fit against the larger curve 64 of large arch 22a. A smaller curve 66 of large arch 22a is sized to fit around the larger curve 68 of small arch 22b. A smaller curve 70 of small arch 22b is sized to fit around the curve 72 of semicircle 24. In an exemplary embodiment, a length of a long rail 30 is equal to a length of a medium rail 32 added to a length of a short rail 40. Moreover, each of the pieces 22a, 22b, 24, 26, 30, 32 and 40 has the same thickness. These features lead to efficiency in manufacturing; materials savings; the ability to compactly and neatly package the pieces; and flexibility in play, as different pieces easily fit together in a variety of configurations. The illustrated and described game components are exemplary and numerous modifications and alternatives are possible.
During play, one or more players uses a mallet 44 to propel a ball 46 through a course constructed on playing surface 12. Such a course starts at tee zone 18, ends at ball receptacle 20, and may include any or all of the other course construction elements 22a-42. Other course construction components can also be used. The course construction elements 22a-42 can be arranged on playing surface 12 within raised perimeter formed by end rails 14 and side rails 16 in any fashion desired by the players. In an exemplary game, a first player designs a first course or hole using whichever of the course construction elements 22a-42 he prefers in any arrangement that he likes. Once all of the players have successfully navigated their respective ball 46 from tee zone 18 to ball receptacle 20, another player may design a new course by reconfiguring any or all of the course construction elements 22a-42 as desired, as well as altering the location and orientations of the tee zone 18 and ball receptacle 20. Entertainment value is thus obtained by not only maneuvering a ball 46 through the course, but also in designing a unique course for each hole.
In a basic game, a course or hole is constructed from tee zone 18, ball receptacle 20, and course construction elements 22a-42 by one or more players. The players start from the tee zone 18 in turn, each player taking a first shot with his respective ball 46 and mallet 44. Then, the player whose ball 46 is farthest from the ball receptacle 20 takes the next shot. The player the second farthest from the ball receptacle 20 takes the following shot, etc. (like traditional golf play rules). Play continues until a player sinks his ball 46 into ball receptacle 20. The first player to sink his ball 46 into ball receptacle 20 wins the hole. If a player's ball 46 jumps the raised perimeter formed by end rails 14 and side rails 16, the player is out of the game for that hole. The winner of the hole constructs the next hole by reconfiguring any or all of the course construction elements 22a-42 as desired, along with tee zone 18 and ball receptacle 20.
In an advanced game, a course or hole is constructed from course construction elements 22a-42 by one or more players. Each player plays the hole by himself and counts the number of shots required to put his ball 46 into ball receptacle 20. If a player's ball 46 jumps the raised perimeter, the player must return his ball to the tee zone 18 and continue playing, thereby adding to the total number of shots taken. The player who sinks his ball 46 into the ball receptacle 20 using the fewest number of shots wins.
After play, game apparatus 10 may be disassembled by disconnecting bores 50 of side rails 16 from pins 48 of end rails 14. Then playing surface 12 may be rolled or folded upon one or both of end rails 14 for portability.
In the foregoing description, the disclosed game has been described with reference to an embodiment comprising tangible, physical pieces. However, the methods of playing a game according to the present disclosure in all embodiments disclosed above and their equivalents may also be played in virtual or digital environment on equipment such as a video gaming machine, a personal or handheld computer, or on any other machine (e.g., personal digital assistant (PDA), cell phone, etc.) capable of simulating a ball rolling among obstacles.
The virtual games can operate in known operating system environments such as Windows, Windows Mobile, Apple, Droid, Unix operating environments, PDA operating environments, video game consoles and other known operating environments. Input entries from players can include audio, device movement or user movement detection, keystrokes, touch screen entry, mouse, stylus and other pointing device entry. Outputs can be displayed to the player on known video displays.
In an exemplary embodiment, one or more players interacts with the game via a graphical user interface such as a computer monitor in conjunction with an input device. The game is presented to the players, who can input information such as the type of game desired, the number of players and optionally information such as their names or avatars. A playing area (e.g., rectangular) is presented to the player(s), along with a finite set of course construction elements. The game can be programmed to allow the player to configure a course or hole within the playing area, using any or all of the course construction elements, in two or three dimensions. In one embodiment, the player constructs the course using a computer mouse by clicking on a course construction element, dragging the element to the desired location and orientation on the playing area, and clicking again to release the course construction element. In an exemplary embodiment, the player is presented with options to rotate the element. If construction in three dimensions is permitted, the player is also presented with an option to rotate or otherwise maneuver each element in a direction orthogonal to the playing area. In an exemplary embodiment, the player enters a command or clicks a button to signal that course construction is complete. Software checks for implementation of required elements such as a tee zone and a ball receptacle and alerts the player if correction is needed.
Each player is accorded a ball, which he propels or otherwise causes to move by a command received through an interface such as device movement or user movement detection, or via a computer mouse, joystick, or touch-screen entry. The virtual balls can be colored or labeled to help a player keep track of his respective ball. The balls travel along or bounce off the course construction elements in a manner that would be expected according to the laws of physics. Scores are automatically computed by software in accordance with the type of game selected by the player(s). The virtual game can be played in accordance with the instructions set forth above. Moreover, the virtual game can be programmed to allow for other forms of play.
Although the subject of this disclosure has been described with reference to several embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the disclosure. In addition, any feature disclosed with respect to one embodiment may be incorporated in another embodiment, and vice-versa.
