Description

 The invention relates to chess demonstration boards and can be widely used in chess clubs in competitions, etc.

 In FIG. 1 shows the design of a cell display panel; in FIG. 2 is a cross-sectional view of FIG. 1; in FIG. 3 - a fragment of a chessboard; in FIG. 4 - view of a chess piece (pawn); in FIG. 5 is a view A of FIG. 4 (white pawn); in FIG. 6 is a view A of FIG. 4 (black pawn).

 The device consists of cells 1 of a demo board according to the number of cells in a chessboard field, i.e. in the amount of "64".

 The display panel contains a base 2, on which is mounted a protective screen 3 made of a transparent material, such as organic glass, and a bulb 4.

 Between the base 2 and the screen 3 in each cell are parallel plates 5 made of opaque material, for example of tin, plastic and any other suitable material, forming combined silhouettes of 6, 7, 8, 9, 10 and 11 chess pieces.

 The ends of the plates 5 are installed on the base 2 and the screen 3 to eliminate unwanted illumination of the adjacent figure.

 Silhouettes 6, 7, 8, 9, 10, and 11 in this embodiment correspond to the following chess figures: 11 - king; 6 - queen; 7 - elephant; 8 - rook; 9 - horse; 10 is a pawn.

The bulbs 4 are placed between the plates 10 and distributed as evenly as possible and connected to the contact blocks 12, connected through a low-voltage power source to the contact groups of the corresponding cells of the chessboard 13 (Fig. 3), which has eight contacts, of which:
contact "1" - common to the "white"field;
pin "8" is common for the conditional "black" field.

 The combination of 1-8 contacts is used to highlight any of the six chess pieces.

 For example, in this particular case, contacts "1" - "2" correspond to a pawn, contacts "1" - "3" - a rook, contacts "1" - "4" - to a knight, contacts "1" - "5" - to an elephant , contacts "1" - "6" - the queen, and when crossing contacts "1" - "7" - the figure "king" will be displayed.

 On the surface of the protective screen 3, in accordance with one or another chess piece, their contours are made within which the screen 3 is transparent, and outside the screen 3 is made opaque.

 Bulbs 4 in each cell have a two-color color; for the “white” field of the bulb itself, you can not paint, but for the “black” field, they are painted, for example, in red, blue or green.

 On each of the chess pieces 14 (Fig. 4-6) are made in full accordance with the contact groups on the cells of the chessboard 13, corresponding to each piece and its color jumpers 15 of the corresponding contacts "1-8" on the chessboard 13.

 As an example of the implementation of switching tools, octal pads can be used, in which the pins 16 and the key pins 17 are installed on the chess pieces, providing an unambiguous orientation of the chess pieces, therefore, switching for highlighting this particular chess piece on a particular square of the field during the game.

 At the same time, on the cells of the chessboard 13, octal sockets are installed - contacts 18 and turnkey response sockets 19.

 Such an implementation is not the only one, for example, reed switches (on a chessboard) can be used as switching elements, and on the figures there are permanent magnets embedded in the body of the figure, while orientation can be carried out either with a key or in another way, for example, special marks on figure and on the field by combining them.

 The device operates as follows.

 At the beginning of the game, when the chess pieces 14 on the chessboard 13 of the game participants are in the starting position, the contacts of the first and second fields for the white and black pieces are bridged, and the chess pieces at the start position of the game are displayed on the demo board. On all other lines, central, all 4 bulbs are turned off - there are no figures on them.

 At the first move, for example, the traditional e2-e4, the white pawn on the second line in the e2 square rises, while the lights 4 that were previously on in the circuit 10 of the pawn are de-energized, i.e. the image of the pawn figure during the transfer from the e2 cell to the e4 cell as if disappears from the field of the demonstration board and only after the pawn figure is placed on the chessboard 13 the player closes the same contacts as before, i.e. “1” and “2” (Fig. 5), but the image of the white pawn will already be on the e4 square.

 Thus, the change in the position of the chess piece is displayed on the demo board, as a result of which the operator is not required to rearrange the images of the chess pieces.

 The design of this device is simple and reliable, and at the same time it allows you to effectively parse a chess game thanks to a very convenient and efficient management.

Claims (2)

 1. A PROJECTION DEVICE FOR DEMONSTRATION OF A CHESS GAME, comprising a chessboard with figures and a display board, consisting of a base with cells according to the number of cells of a chessboard, light bulbs and a protective screen fixed to the base, characterized in that in each cell of the display board there are parallel plates made of opaque material, the ends of which are mounted respectively on the base and protective screen, on the surface of which contours of chess pieces are made, outside the contours of which are protective The th screen is opaque, between the parallel plates there are light bulbs painted in two colors installed in the holes of the base and connected to the contacts located on the chessboard, and the chess pieces are equipped with jumpers for switching the corresponding contacts on the chessboard.  2. The device according to claim 1, characterized in that the contacts on the chessboard are made in the form of an octal block, two contacts of which are common for chess pieces of different colors, and the remaining contacts correspond to chess pieces on which the reciprocal octal blocks are made.
