Abstract

PROBLEM TO BE SOLVED: To obtain high amusement in a game by providing a board to house a plurality of pieces in an arrangement of rows and columns without gaps, forming each piece into a shape in which the four vertex parts of a square are all notched, and providing patterns to form one picture by combination for the contact parts of the adjacent pieces. SOLUTION: The puzzle 1 is constituted of one board 2 and nine pieces 3, and the board 2 is formed in such a way as to comprise a recessed part in which the nine pieces 3 are fitted by a bottom plate 21 and wall plates 22 arranged in the circumference of the bottom plate 21. Each piece 3 is formed, for example, in an octagonal prism by notching all the four vertex parts of a square with low height, and patterns 31 to complete one picture from the patterns 31 of adjacent pieces 3 are each printed on the four-side parts of the surface of each piece 3. The patterns 31 are selected for nine pieces 3 in such a way that the same and one pattern does not exist in the completed patterns 31 and that the completed patterns 31 are difference form one another by the combination of colors in addition. As notched parts A are each formed between the pieces 3 when the pieces 3 are fitted in the board 2, it is easy to remove the pieces 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a puzzle consisting of pieces having a novel shape.

[0002]

2. Description of the Related Art There are many types of inset puzzles. All pieces (sometimes called pieces) have the same shape and can be fitted solely with a pattern, or pieces with different external shapes such as a jigsaw puzzle can be fitted with reference to both the shape and the pattern, or There is a type that depends only on the shape like a certain kind of building block puzzle, and the like.

[0003]

In both types of puzzles, it is necessary to repeatedly insert and remove pieces while proceeding toward completion. However, it is difficult to remove pieces once fitted. there were.

[0004]

The present inventor has finally completed the puzzle of the present invention as a result of intensive studies in view of the current situation. The feature of the present invention is that nine squares are arranged in 3 × 3 without gaps. And a puzzle consisting of nine pieces, each of which has four squares.
All the vertices are cut out in the same shape, and the patterns drawn on the piece are mutually non-symmetrical four types of combinations drawn across the contact surfaces with the adjacent upper, lower, left and right pieces. It is different.

[0005] Here, the board is a member for fitting and arranging nine pieces into three pieces by three pieces without gaps. The other points are not limited at all, but usually have a structure like a “plate” or “shallow box” surrounded by a ridge of a slight height. It is preferable that the height of the ridge is set so that the upper surface of the piece is higher than the upper end of the ridge when the piece is fitted so that the piece can be easily taken out.

The piece has a shape that fits in a square having a width of 1/9 of the portion of the board to be fitted, but has a cross section that is not square but has all four vertices cut out. The present invention includes not only an octagon cutout in a straight line but also a cutout in a curved line or a broken line. The meaning of the “shape in which the four vertices of the square are notched” means that it is inscribed in the square, and it is assumed that some of the four sides constituting the notched square remain (the square In the case of the inscribed circle, the "point" is inscribed instead of the "side", and this is also included in the "shape where four vertices of a square are cut out"). By satisfying this condition, the nine pieces can be firmly fitted to the board.

On the upper surface of the piece, a picture is drawn.
This picture is drawn so as to straddle a contact portion with an adjacent piece. In the case of a piece arranged at the center of the board, the adjacent pieces are all above, below, left and right. Therefore, there are four contact portions with adjacent pieces.
These four patterns are independent of each other, and if all four are not prepared, it will be a mistake. That is, although there are four pictures on the outer periphery of the piece, all of them are only one of the two pictures obtained by dividing each picture. It is assumed that the bisector is not a pattern which is point-symmetric at its center.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail.

FIG. 1 shows an example of a puzzle 1 according to the present invention (hereinafter referred to as the present invention puzzle 1). As is clear from the drawing, the present invention puzzle 1 comprises one board 2 and 9 And a piece 3. Note that all the pieces 3 have a picture on the surface, but the drawing is omitted in this figure.

The board 2 is formed by a bottom plate 21 and a wall plate 22 arranged around the bottom plate 21 and has a recess into which nine pieces are fitted.

FIG. 2 shows one of the pieces 3, which is an octagonal column having a low height, and a picture 31 is described on the surface thereof. The picture 31 is an arrow pattern in the present example, and either the tip side or the base side of the arrow is drawn on every other eight sides of the octagon. The color of the arrow pattern is also four colors, and depending on the combination of whether to describe the tip side or the base side and what the color is, the nine pieces 3 are different from each other without the same thing at all. Is chosen.

FIG. 3 is a plan view of an example of the puzzle 1 of the present invention, showing a state in which all nine pieces 3 having an octagonal column are fitted. Since the fitting portion of the board 2 has a size in which nine squares are laid out three by three, a notch A is formed when nine pieces 3 having an octagonal column are fitted. Since the four cutout portions A are large at the center, if the fingertip is inserted here, the stored piece 3 can be easily taken out.

The pattern 31 of the piece 3 in the puzzle 1 of the present invention is not limited to an arrow pattern, as a matter of course.
There may be various types, and the shape of the cutout portion A is not limited to that shown in the drawings, but may be various. FIG.
(A) and (b) show examples of such a case.

[0014]

As described in detail above, the present invention is an extremely advanced invention in which a piece once fitted can be easily taken out.

Claims (1)

[Claims] 1. A puzzle consisting of a board on which nine squares can be arranged in 3 × 3 without gaps and nine pieces, wherein the pieces have the same four vertex parts in the square. It is notched in shape, and the patterns drawn on the pieces are different from each other due to four non-symmetric combinations drawn across the contact surfaces with the adjacent upper, lower, left and right pieces.
