MULTILEVEL CHESS OR CHECKER BOARD BACKGROUND OF THE INVENTION This invention relates to game boards and more particularly to a chess or checker board having a variable topography.
Conventional chess or checker boards typically are two dimensional devices. The invention disclosed hereinafter enables the participants in a conventional chess or checker game to design the height of the chess or checker board by varying the height of the squares comprising the board, prior to commencing the game, while adhering to the conventional alternating color design of the board. The particular game is played thereafter on a board having varying topography which adds difficulty and interest to the game.
A number of game boards having blocks or other pieces which are placed upon a playing surface are known in the art. In general, the blocks themselves are the playing pieces, the intention of the game being to attain a desired pattern or disposition of the blocks. Our invention is distinguished from these prior art devices in the particular construction disclosed and in the fact that the topography pieces serve as supporting seats for the regular individual checkers or chessmen used in the conventional game or chess or checkers.
One of the objects of this invention is to provide a game board in which the height of the squares may be varied.
- Another object of this invention is to provide a game board having a plurality of topography varying parts associated with it.
Yet another object of this invention is to provide a chess or checker board having topography varying pieces which serve as supporting seats for individual chessmen or checkers.
Other objects of this invention will be apparent to those skilled in the art in light of the following description and accompanying drawings.
SUMMARY OF THE INVENTION In accordance with this invention, generally stated, a game board having a plurality of squares displayed thereon is provided with a peripheral lip and a plurality of supporting pieces. The supporting pieces have a length and width dimension corresponding to the squares displayed on the board, and have varying height dimensions. Means are provided for attaching the supporting pieces to the board or to other supporting pieces. The topography of the board is varied by preselected distribution of the supporting pieces prior to the start of play. Play is conducted according to conventional chess or checker rules, the supporting pieces serving as seats for the playing pieces of the game.

FIG. 5 is a sectional view taken along the lines 5-5 of FIG. 2; and
FIG. 6 is a sectional view of a second illustrative embodiment of game board of this invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIG. 1, reference numeral 1 indicates the game board of this invention. The board 1 generally is rectangular in plan having an upper surface 2 and a lower surface 3.
The upper surface 2 has a plurality of squares 4 disposed on it in a conventional checker board pattern. That is, the squares 4 are of alternating colors disposed in eight rows of eight squares each. The squares have a length dimension 25 and a width dimenstion 26. The board preferably is divided into two sections which are foldable for storage along a pair of hinges.
A peripheral lip. 6 extends about the perimeter of the board 1 and is important in holding a plurality of supporting pieces 7, later described in detail.
The preferred construction for the board 1 is shown in cross section in FIG. 5. A layer 9, the outer boundary of which forms the upper surface 2, has the squares 4 disposedon it. Layer 9 may comprise any of a variety of material layers. For example, the layer 9 may be a vinyl overlay having the squares printed on it. A layer 10 is interposed between the layer 9 and a supporting layer 11. The layer 10 preferably is constructed from a material capable of being magnetized. Thin foil works well, for example. The layer 11 may be constructed from a variety of materials. Both plastic and wood work well. Plastic isparticularly convenient as the lip 6 may be integrally formed with the layer 11. The layers 9, 10 and 11 may be attached to one another by any convenient method. Epoxy or other adhesives work well. It is convenient to attach a number of feet 8 to the lower surface 3 of-layer 11 preferably at each of the four corners of the board 1. The feet 8 may be constructed from a non-skid material. Rubber works well, for example, Other materials or locations for the feet 8 are acceptable. Thus, the feet 8 may be integrally formed with the layer 11, or rubber feet, when used, may be manufactured separately and later attached to surface 3.
The game board 1 is intended for use with the plurality of supporting pieces 7, an example of which is shown in FIG. 3 at 12. The supporting element 12 generally is rectangular in plan having a length dimension L, a width dimension W, and a height dimension H. The length and width dimensions of the supporting element 12 correspond to the length 25 and width 26 of the squares 4. Each supporting element 12, however, has a varying height dimension H. Individual elements 12 of the supporting piece plurality 7 may be constructed from any suitable material. Again, wood or plastic work well. In the preferred embodiment, each of the supporting elements 12 has a member 13 mounted in it. The
member 13 is constructed from magnetic material and may have any convenient shape, although a rectangular shape is illustratively shown. The member 13 may be molded in the supporting element 12 or provisions may be made for its insertion after manufacture of the supporting element 12. The element 12 may be removably mounted to the board 1 by magnetizing either the member 13 or the layer 10.
A second embodiment of game board of this invention is shown in FIG. 6, and like reference numerals are used where appropriate. As there illustrated, a board 14 has a playing area 15 having an upper surface 16 and a lower surface 17. The lip 6 extends about the periphery of the playing area 15. The surface 16 has the checker board indicia displayed on it. Each of the squares 4, in the embodiment of FIG. 6, has a receptacle 18 formed in it. The receptacles 18 are closed at the bottom in the embodiment illustrated, however, they may extend through the playing area 15, between the surfaces 16 and 17, if desired. The receptacles 18 are sized to receive a male member 19 of a supporting element 20, a plurality of which comprises the supporting pieces 7.
Supporting element 20, like supporting element 12, has a length L dimension and width W dimension corresponding to the length and width dimensions 25 and 26 respectively of the squares 4. Again, the height dimension H varies in embodiments of this invention. The male member 19 is attached to the supporting element 20 by any convenient method. A tight press fit is suitable, for example. The supporting element 20 may have an opening 21 in it which serves as a receptacle for a male member 19 of another supporting element 20. Use of the supporting elements 20 in this manner is described hereinafter. As described in conjunction with the embodiment of FIG. 2, the board 14 may have feet 8 positioned at convenient locations on the surface 3 of the playing area 15.
The game board of this invention is used in the conventional games of chess or checkers. Its function is to vary the topography of the conventional chess or checker board to increase the conceptional difficulties of those games. The supporting elements 12 and 20 themselves have no point value nor are they intended as playing pieces in the game. They serve, as their name implies, as supports for the chessmen or checkers. The supporting elements 12 and 20 are capable of use in a variety of ways Thus, in one embodiment, the supporting elements 12 or 20 are provided with definite but distinct height measurements. For example, the supporting elements 12 or 20 may be utilized with a checkerboard having one inch squares displayed on it. Supporting elements for this last mentioned board would have height measurements of one-half, l, l /2 and 2 inches, for example. Half of each of the various height sized supporting elements are colored the same as one of the colors ofthe squares 4. The supporting elements 12 and 20 are intended to be placed on the board 1 prior to commencement of the conventional chess or checker game. A player has five height choices in setting up the checkerboard. That is, he may elect not to use any of the supporting elements, or he may select one ofthe four sizes provided. The supporting elements are placed on the board 1 and either of the games of checkers and chess is played according to its normal rules.
Ifdesired, a single size of the supporting elements 12 or 20 may be provided. Again, half of the supporting elements match one of the colors used in conjunction with the squares 4. For example, with l inch squares on the board 1, the height of each supporting element 12 or 20 may he one-half inch. Thereafter, each player may use the supporting elements as building blocks to vary the height of the squares 4 in one half inch increments. However, the height of any one square is not limited to any predetermined height, as in the first embodiment described above where each of the supporting elements are manufactured to a preselected height. Regardless of which supporting element embodiment is utilized, a sufficient number of the elements comprising the plurality of supporting pieces 7 are provided to permit the players to vary the height of each square on the board if desired.
The supporting elements 12 and 20 may be manufactured for use in either of the two situations described. Thus, when the magnetized member 13 of the supporting element 12 is utilized, a plurality of the elements 12 may be aligned so that a stack of the supporting elements 12 is obtained. In the alternative, the male members 19 of the supporting elements 20 may be inserted in the receptacles 18 to provide a first height to a particular square, and additional height may be obtained by stacking the supporting elements 20 atop one another, inserting members of succeeding supporting elements 20 in opening 21 of the preceding one. In either situation, the peripheral lip 6 is an aid in maintaining the supporting piece plurality 7 on the board 1 and keeps the elements in alignment, the result of which is a close fitting square structure in plan.
'Numerous variations, within the scope of the appended claims, will occur to those skilled in the art in light of the foregoing description and accompanying drawings. Thus, various materials may be utilized in the construction of both the supporting elements and the board of this invention, in addition to those described above. Other height dimensions may be used for the supporting elements. Certain embodiments of the board 1 may be nonfoldable, eliminating use of the hinges. These variations are merely illustrative.
