Abstract

The utility model relates to teaching aids or chess toys, in particular to a connect four. The connect four consists of four chess pieces and a chess board, wherein a first chess piece has a shape of a regular triangle of which the side length is 1 centimeter, a second chess piece has a shape of a diamond of which the side length is 1 centimeter, a third chess piece has a shape of an isosceles trapezoid of which the upper bottom side length is 1 centimeter, the back waist length is 1 centimeter, and the lower bottom side length is 2 centimeters, and a fourth chess piece has a shape of a regular triangle of which the side length is 2 centimeters; and the chess board has a shape of a regular triangle, and the side length of the chess board is integer multiples of 1 centimeter. The connect four is simple in structure and low in cost; a chess toy which is similar to the game of go is provided according to the topology and geometry knowledge, profound knowledge is implied in seemingly simple rules, room for interpretation is reserved for people, and the connect four is suitable for training the thinking ability of people.

Description

Four sub-chesses

Technical field

The utility model relates to the chess toy four sub-chesses of teaching aid or chess toy, particularly a kind of similar go, can make the teacher have a kind of effective instrument to make the student use the geometric knowledge of learning after school, and use one's hands and brains.Through the memory capability of training of students, cultivate thinking in images, excite the potential innovation ability of people.

Background technology

Technology content is on the low side in the present like product; Particularly the people in modern living standard improves, and need on higher knowledge aspect, carry out amusement, for adapting to this variation; Said four sub-chesses can address this problem; Seem simple, it is also remarkable to descend, and a kind of senior chess toy of similar go is provided.

Summary of the invention

In order to solve the apparatus problem that people use one's hands and brains, the utility model can make people through using one's hands and brains according to the four sub-chesses that topological geometric knowledge provides, and cultivates thinking in images, and the training memory capability improves intellectual level.

The scheme that the utility model adopted is:

Four sub-chesses are made up of four chess pieces and chessboard; First chess piece is the equilateral triangle of 1 centimetre of the length of side; Second chess piece is the rhombus of 1 centimetre of the length of side; The 3rd chess piece is the isosceles trapezoid that goes up 1 centimetre of bottom side length, long 1 centimetre of waist, 2 centimetres of the length of sides of going to the bottom, and the 4th chess piece is the equilateral triangle of 2 centimetres of the length of sides; Said chessboard is an equilateral triangle, and the length of side of said chessboard is 1 centimetre a integral multiple.As a base unit, the chess piece that both sides held when playing chess must be the integral multiple of said base unit with said four chess pieces, and both sides' chess piece color is different.Chess rules: one: begin and the edge-to-edge to contact; Two: beginning to circulate according to said four chess pieces successively carries out in an orderly manner, but first begin by oneself the decision, such as first begin be said the 3rd chess piece then next step must be said the 4th chess piece, successively the circulation; Can not move after beginning, be defeated with a side that can't fall chess piece more again, and the opposing party is the winner.What both sides should notice constantly that the other side's next one falls in playing chess will be any chess piece, and the person of playing chess need have certain topological geometric knowledge, is calculating the other side's chess piece is not fallen down at last, thereby is winning, and the probability of draw in chess is little.

The beneficial effect of the utility model is:

As if four sub-chess simple structure costs are low, are the chess toys of a kind of similar go of providing according to topological geometric knowledge, see containing profundity among simple, left the leeway of people's imaginations for.Changeable according to the used chessboard of different crowd, as to be fit to train people thinking ability.

Among the figure, 1. first chess piece, 2. second chess piece, 3. the 3rd chess piece, 4. the 4th chess piece, 5. chessboard.

The specific embodiment

Like Fig. 1 to Fig. 4 is the sketch map of said four chess pieces (1) (2) (3) (4); Four sub-chesses are made up of said four chess pieces and chessboard; First chess piece is the equilateral triangle of 1 centimetre of the length of side; Second chess piece is the rhombus of 1 centimetre of the length of side, and the 3rd chess piece is the isosceles trapezoid that goes up 1 centimetre of bottom side length, long 1 centimetre of waist, 2 centimetres of the length of sides of going to the bottom, and the 4th chess piece is the equilateral triangle of 2 centimetres of the length of sides.

Like Fig. 5 is the sketch map that said chess piece contacts with the chess piece edge-to-edge, allows as long as satisfy an edge-to-edge of place contact rule when beginning.

Like Fig. 6 is the sketch map that said chess piece contacts with the chess piece angle equal edge, begins like this not meet rule, will lose the interest and the standardization of playing chess.

Like Fig. 7 is the ongoing example of playing chess, and the length of side of said chessboard (5) is 1 centimetre a integral multiple, and the length of side of chessboard described in this example is 13 centimetres, and the room for maneuver that generally surpasses 10 centimetres is bigger.It among the figure example of both sides' preceding 4 hands of beginning to play chess from the lower left corner; All used the chess piece of a said base unit by regular both sides; Be the 3rd chess piece elder generation of white side, the 4th chess piece follow-up of black piece, all circulate successively and carry out in an orderly manner according to said four chess pieces; The person of playing chess need have certain topological geometric knowledge, is calculating the other side's chess piece is not fallen down at last.Can not move again after beginning, utilize existing magnetic technique can accomplish closely to inhale mutually between said chess piece and the said chessboard, to avoid objectively mobile of said chess piece.

Claims

1. sub-chess; Constitute by four chess pieces and chessboard; It is characterized in that: first chess piece is the equilateral triangle of 1 centimetre of the length of side; Second chess piece is the rhombus of 1 centimetre of the length of side, and the 3rd chess piece is the isosceles trapezoid that goes up 1 centimetre of bottom side length, long 1 centimetre of waist, 2 centimetres of the length of sides of going to the bottom, and the 4th chess piece is the equilateral triangle of 2 centimetres of the length of sides; Said chessboard is an equilateral triangle, and the length of side of said chessboard is 1 centimetre a integral multiple.
