Abstract
ABSTRACT OF THE DISCLOSURE
A circular game area is defined on a substantially planar game surface and includes fourteen generally straight, elongated radial zones spaced about and extending outward from a central zone. Each of the radial zones includes eight discrete spaces of two alternating colors spaced there-along and each set of corresponding spaces of said zones are disposed in an annular path extending about the central zone and the colors of each set of annular path spaces alternate thereabout. The fourteen zones include a pair of home zones arranged diametrically opposite each other on opposite sides of said central zone and with six of said radial zones disposed between said home zones in each direction extending about the central zone. A discrete boundary line is defined between adjacent radial zones and the boundary lines between each home zone and the adjacent non-home zones are visually distinct.

Description
1~6~08 Various different forms of chess heretofore have been provided including both two and three dimensional ches6 and also including chess which is played on a circular playing area. However, most of these pre-viously known forms of chess do not offer more than one or two variations of chess play from conventional chess play and do not enable attack by a single player piece upon another opposing player piece Erom opposite direc-tions. Accordingly, a need exists for a more comprehensive form of chess which may be played to the satisfaction of more serious and skilled chess players having a desire for variations.
Examples of various different forms of circular chess games includ-ing some of the general structural and operational featurea of the instant invention are disclosed in U.S. Pat. Nos. 3~776,554, 3,851,883, 3,917,273, 3,918,715 and 4,322,085.
The circular chess game of the instant invention utilizes a circular playing area including fourteen generally straight, elongated and radially extending zones spaced about and extending outward from a central zone. Each of the radial zones includes eight discrete spaces of two alternating colors spaced therealong and each set of corresponding spaces of the zones are dis-posed in an annular path extending about the central zone. The colors o each set of annular path spaces alternate thereabout. The fourteen zones includes a pair of home zones arranged diametrically opposite each other on opposite sides of the central zone and with six of the radial zones disposed between the home zones in each direction about the central zone. In this manner, each of the major chess pieces may be disposed on the corresponding spaces of a selected home zone and either a s;ngle or double set of pawns may be used and placed on the zone or zones adjacent the home zone. If only a single set of pawns is used, the Rook pieces may be limited to movement only toward the other opposing home space past the associated pawns until such time as the Rook pieces have moved laterally from their initial annular paths extend-ing about the central zone. This, of course, would prevent first moves of the Rook pieces in reverse to capture the corresponding opposing rook pieceFurther, a similar limitation could be placed upon the Queen pieces.
The main object of this invention is to provide a novel form of circular chess which may be played with a conventional set of chess pieces including only one set of pawns or which may also be played with a modified set of chess pieces including a double set of pawns.
Still another object of this invention is to provide a form of cir-cular chess which will require considerably more expertise and concentration by an accomplished chess player.
Yet another object of this invention iB to provide a form of chess which offers a considerable variation from the conventional form of chess.
A final object of this invention to be specifically enumerated herein is to provide an improved chess game in accordance with the preceding objects and which will conform to conventional forms of manufacture, be of simple construction and inter~sting to use so as to provide a device that will be economically feasible, long lasting and a welcome variation to accomplished chess players.
Figure 1 is a plan view of the circular chess playing area of the instant invention and illustrating the manner in which not only a conventional ~et of chess pieces may be used but also the manner in which a modified set of chess pieces incorporating a double number of pawns may be used;
Figure 2 is a side elevational view of the gameboard illuserated in Figure l; and Figure 3 is a further top plan view of the gameboard or area illustrating the manner in which the major chess pieces other than the pawns may move in opposite directions about the circular playing area during attack and defensive moves.
Referring now more specifically to the drawings, the numeral 10 generally designates the gameboard of the instant invention. The gameboard 10 is substantially circular and defines a central circular ~one 11 about ~246~013 which fourteen generally straight, elongated radial zones 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36 and 38 are defined with each zone includ-ing eight discrete space~ 40, 42, 44, 46, 48, S0, 52 and 54. Each ~et of eight diacrete spaces are Oe two alternating colors comprising white and black and each set of corresponding spaces of the zones 40-54 are disposed in annular paths 56, 58, 60, 62, 64, 66, 68 and 70 extending about and con-centric with the central zone 11. The colors of the spaces 40-54 in each of the zones 56-70 alternate ~hereabout.
Adjacent zones 16-26 are separated by radial lines 72, adjacent zones 28-38 are separated by siloilar lines 74 and the home zones 12 and 14 are each separated from the adjacent zones by darker lines 76. In addition, the adjacent annular paths 40-54 are separated by lines 78. Accordingly, each of the spaces 40-54 i8 clearly defines relative to adjacent spaces.
From Figure 1 of the drawings, it may be seen that the major ch ss pieces may be placed in the home zones 12 and 14 in the same manner in which they are placed along remote edges of a conventional square chess board. In ; addition, if only a single set of pawns 80 is to be used, the pawns 80 may be placed in either the zones 16 and 26 or the zones 28 and 38. However, if double sets of pawns are to be used, the pawns may be placed in the zones 16, 26, 28 and 38.
With attention now invited more specifically to Figure 2, it may be seen that the gameboard 10 comprises a circular game panel 81 mounted upon a suitable base 82. The game panel 81 may have the design of the playing area either printed, embossed or otherwise formed thereon.
With attention now invited more specifically to Figure 3, it may be seen that the major game pieces, the King 84, Queen 86, Bishops 88 and 90, Knights 92 and 94 and Rooks 96 and 98 may be initially positioned along the zone 14. The King 84 may, of course, move one space in any direction and the Bishops 88 and 90 may move in what would ordinarily be a diagonal path in either direction, but which paths on the gameboard 10 comprise either arcuate ,. . ~ , . , , . . , ~ . ....... ~.
~2~6~0~
paths of increasing radius of curvature or arcuate paths of decreasing radius of curvature. In addition, the Knights 92 and 94 may move in the conventional manner including either two spacea forward and one space laterally or one space forward and two spaces laterally. Of course, the Knights 92 and 94 may also move in rearward directions and in lateral directions in the same manner.
Further, the Rooks 96, 98 may move either in the zones 40-54 or the zones 14-38. Finally, the Queen 86 may, of course, move either as a Rook or Bishop.
Therefore, it may be noted that a game of chess played on the game-board lO may be quite challenging to even an experienced or accomplished player of conventional chess and may offer a pleasing alternative to conventional chess.
Examples of various different forms of circular chess games includ-ing some of the general structural and operational featurea of the instant invention are disclosed in U.S. Pat. Nos. 3~776,554, 3,851,883, 3,917,273, 3,918,715 and 4,322,085.
The circular chess game of the instant invention utilizes a circular playing area including fourteen generally straight, elongated and radially extending zones spaced about and extending outward from a central zone. Each of the radial zones includes eight discrete spaces of two alternating colors spaced therealong and each set of corresponding spaces of the zones are dis-posed in an annular path extending about the central zone. The colors o each set of annular path spaces alternate thereabout. The fourteen zones includes a pair of home zones arranged diametrically opposite each other on opposite sides of the central zone and with six of the radial zones disposed between the home zones in each direction about the central zone. In this manner, each of the major chess pieces may be disposed on the corresponding spaces of a selected home zone and either a s;ngle or double set of pawns may be used and placed on the zone or zones adjacent the home zone. If only a single set of pawns is used, the Rook pieces may be limited to movement only toward the other opposing home space past the associated pawns until such time as the Rook pieces have moved laterally from their initial annular paths extend-ing about the central zone. This, of course, would prevent first moves of the Rook pieces in reverse to capture the corresponding opposing rook pieceFurther, a similar limitation could be placed upon the Queen pieces.
The main object of this invention is to provide a novel form of circular chess which may be played with a conventional set of chess pieces including only one set of pawns or which may also be played with a modified set of chess pieces including a double set of pawns.
Still another object of this invention is to provide a form of cir-cular chess which will require considerably more expertise and concentration by an accomplished chess player.
Yet another object of this invention iB to provide a form of chess which offers a considerable variation from the conventional form of chess.
A final object of this invention to be specifically enumerated herein is to provide an improved chess game in accordance with the preceding objects and which will conform to conventional forms of manufacture, be of simple construction and inter~sting to use so as to provide a device that will be economically feasible, long lasting and a welcome variation to accomplished chess players.
Figure 1 is a plan view of the circular chess playing area of the instant invention and illustrating the manner in which not only a conventional ~et of chess pieces may be used but also the manner in which a modified set of chess pieces incorporating a double number of pawns may be used;
Figure 2 is a side elevational view of the gameboard illuserated in Figure l; and Figure 3 is a further top plan view of the gameboard or area illustrating the manner in which the major chess pieces other than the pawns may move in opposite directions about the circular playing area during attack and defensive moves.
Referring now more specifically to the drawings, the numeral 10 generally designates the gameboard of the instant invention. The gameboard 10 is substantially circular and defines a central circular ~one 11 about ~246~013 which fourteen generally straight, elongated radial zones 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36 and 38 are defined with each zone includ-ing eight discrete space~ 40, 42, 44, 46, 48, S0, 52 and 54. Each ~et of eight diacrete spaces are Oe two alternating colors comprising white and black and each set of corresponding spaces of the zones 40-54 are disposed in annular paths 56, 58, 60, 62, 64, 66, 68 and 70 extending about and con-centric with the central zone 11. The colors of the spaces 40-54 in each of the zones 56-70 alternate ~hereabout.
Adjacent zones 16-26 are separated by radial lines 72, adjacent zones 28-38 are separated by siloilar lines 74 and the home zones 12 and 14 are each separated from the adjacent zones by darker lines 76. In addition, the adjacent annular paths 40-54 are separated by lines 78. Accordingly, each of the spaces 40-54 i8 clearly defines relative to adjacent spaces.
From Figure 1 of the drawings, it may be seen that the major ch ss pieces may be placed in the home zones 12 and 14 in the same manner in which they are placed along remote edges of a conventional square chess board. In ; addition, if only a single set of pawns 80 is to be used, the pawns 80 may be placed in either the zones 16 and 26 or the zones 28 and 38. However, if double sets of pawns are to be used, the pawns may be placed in the zones 16, 26, 28 and 38.
With attention now invited more specifically to Figure 2, it may be seen that the gameboard 10 comprises a circular game panel 81 mounted upon a suitable base 82. The game panel 81 may have the design of the playing area either printed, embossed or otherwise formed thereon.
With attention now invited more specifically to Figure 3, it may be seen that the major game pieces, the King 84, Queen 86, Bishops 88 and 90, Knights 92 and 94 and Rooks 96 and 98 may be initially positioned along the zone 14. The King 84 may, of course, move one space in any direction and the Bishops 88 and 90 may move in what would ordinarily be a diagonal path in either direction, but which paths on the gameboard 10 comprise either arcuate ,. . ~ , . , , . . , ~ . ....... ~.
~2~6~0~
paths of increasing radius of curvature or arcuate paths of decreasing radius of curvature. In addition, the Knights 92 and 94 may move in the conventional manner including either two spacea forward and one space laterally or one space forward and two spaces laterally. Of course, the Knights 92 and 94 may also move in rearward directions and in lateral directions in the same manner.
Further, the Rooks 96, 98 may move either in the zones 40-54 or the zones 14-38. Finally, the Queen 86 may, of course, move either as a Rook or Bishop.
Therefore, it may be noted that a game of chess played on the game-board lO may be quite challenging to even an experienced or accomplished player of conventional chess and may offer a pleasing alternative to conventional chess.
