Description

The invention relates to clocks used in board games, in particular in games such as chess.

The purpose of the invention is to improve ease of use.

Fig. 1 shows an embodiment of a chessboard with a built-in clock; Fig. 2 is a section A-A in Fig. 1; Fig. 3 is a circuit for connecting timers.

A chess clock can be embedded in a chessboard 1, each side of which is divided into equal parts, for example 8, 10 or 12 parts, contains electronic timers 2 and 3, which are installed from the first and last horizontals. In this case, each of the timers is facing the player, as shown in FIG.

Buttons 4 and 5 of the players and indicators 6, 7 are also installed on the board 1. Buttons 4 and 5 should be installed on the left side (under the left hand) of players. Power supply via button 5 is connected to the R input of the RS trigger 8, and through button 4 to the S input. In this case, the capacitor 9 of the initial state is also connected to the S-input.

The outputs of the trigger 8 through the circuit And 10 and 11, respectively, are connected to the inputs of the timers 2 and 3 corresponding decoders 12 and 13 and the indicators 14 and 15.

To the inputs of the circuits And 10 and 11 connected to the output of the generator 16 and power through the node 17 run. To the inputs of timers 2 and 3 connected node 18 installation O.

Indicators 6, 7 operate on the signal of the generator 16 to the corresponding timers

2iZ.

Chess also contains two sets of pawns and pieces of different colors. The number of pieces and pawns in each set is determined by the number of equal parts of each side.

Before the start of the game, timers 2 and 3 are adjusted so that after the end of the regulated time the buzzer will operate, as in a normal electronic clock.

Through the button 18 on the timers 2 and

3 set the initial time, for example, 17.00.

The initial position of the switch 17 - Off.

At the beginning of the game, by turning the knob 17 to the Enabled position in the capacitor 9, an electrical pulse is generated, which is fed to the input S of the trigger 8, so that the logical output of the latter is set to logical 1, and to the inverse - logical O. After

WITH

The impulse of the generator 16 through this circuit 11 is transmitted to timer 3, i.e. White's countdown begins. After White’s move, the player presses the button 5 with his left hand, an electric pulse arrives at the R-input of the trigger 8, resulting in a logical O at the direct output of the latter, and a logical 1 at the inverse output. As a result, the generator 16 pulses through the circuit 10 arrive at timer 2, Black starts counting down, the generator signals to timer 3 stop. Its indicator 15 will indicate that White uses the time until the button 4 is pressed by the opponent after his turn. Then (after the move and on button 4 atm) generator signals again fed to the timer 3, the countdown will extend white and black - Cessation schats.

When the generator signals arrive at timer 3, i.e. White’s timing is running, the control lamp 6 lights up or flashes from the generator 16 signals, and while counting

Black time - lamp 7. At the end of the regulated time of one of the players, an audible alarm sounds, notifying of the end of the game.
