Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field This invention relates to the invention in which each side of a cube or a rectangular parallelepiped (numbers attached to each puzzle piece arranged here, colors attached to Kanji or heart shapes or inverted triangles, etc.) This relates to a three-dimensional puzzle in which you can enjoy matching recognizable marks by moving puzzle pieces vertically and horizontally around each side of the cube (
Six axes were provided facing this, and twenty-six small cubes were attached to these axes, and by rotating the small cubes about each axis, the colors on each side of the cube matched. .

Purpose: The purpose of this invention is to provide a new three-dimensional puzzle that is different in structure from conventional three-dimensional puzzles, allows the enjoyment of complex puzzles, has a simple structure, and allows smooth movement of each puzzle piece. It's about doing.

EXAMPLE Hereinafter, an example of a three-dimensional puzzle embodying the present invention will be described with reference to FIGS. 1 to 4.

Reference numeral 1 denotes a cubic support block made of a synthetic resin material, and grooves 2 are formed in the vertical direction (32 grooves and 2 grooves in the horizontal direction) circumferentially around the surface of the support block 1. There are four intersection points of the grooves 2 formed vertically and horizontally on each surface.The surface of each edge of the support block 1 (the ridgeline where each surface of the cube intersects perpendicularly) and the bottom of the grooves 2 are formed in an arc shape. Reference numeral 3 denotes a clamping piece protruding into the groove 2 at the upper part of each side of the groove 2 so as to face each other with a predetermined gap, and the outer surface thereof is a support plate. It is flush with the outer surface of Tsuku 1.

Reference numeral 4 denotes a puzzle piece, the outer surface of which is formed into a square shape, and the inner peripheral edge of the puzzle piece having a tapered shape. Reference numeral 5 denotes an engaging projection protruding from the inner surface of the puzzle piece 4, and a large-diameter fitting portion 6 is provided at the tip.

The puzzle pieces 4 are attached to two pairs of support blocks 1 in the state shown in FIGS. 3 and 4.

That is, the engaging protrusion 5 of the puzzle piece 4 is fitted into the gap between the clamping pieces 3, and the inner surface of the puzzle piece 4 is in sliding contact with the surface of the support block 1. Further, the fitting portion 6 at the tip of the engagement protrusion 5 is in sliding contact with the bottom surface of the groove 2 on its outer end surface, and on the inner surface of the holding piece 3 on its inner surface. Therefore, the spear piece 4 is held by the support block 1 so that it cannot fall off.

Furthermore, each surface number of the support block 1 is such that four puzzle pieces 4 equal to the number of intersections of the grooves 2 formed on each surface are mounted adjacent to each other so that their side surfaces are in contact with each other vertically and horizontally. The puzzle pieces 4 located on one side of the support block 1 are attached adjacent to each other with their tapered inner peripheral edges in contact with each other. 1(
In this case, a total of 24 puzzle pieces 4 are attached, and so that the colors attached to the heart-shaped marks on each side of the support block 1 are different, the 4 puzzle pieces 4 are made the same color, and the color of 6 is different. It is attached to the outer surface of each puzzle piece 4. Further, the directions of the heart-shaped marks are aligned on each surface.

In addition, in order to assemble the 24 puzzle pieces 4 to the support block 1, divide the support block 1 at an arbitrary point, fit each puzzle piece 4 into the groove 2, and then glue the divided support blocks together.
It is easier to assemble if it is integrally formed by fitting or the like.

In the three-dimensional puzzle constructed as described above, the eight puzzle pieces 4 in each row, vertical and horizontal, arranged around the support block 1 move in the same direction in conjunction with each other. Therefore, each puzzle piece 4
The player can enjoy playing the game of matching the directions and colors of the heart-shaped marks on the four puzzle pieces 4 that appear on each side of the support block 1 while moving it to an arbitrary position. This solution is very complicated, but at least if the direction and color of the 7%-g mark match, you can move each puzzle piece 4 to any position (even if you move it, you can follow the reverse procedure). This ensures that the orientation and color of the note-shaped marks match.

Further, the eight puzzle pieces 4 in each row and column surrounding the support block 1 are arranged adjacent to each other, and the surface of the support block 1 and the bottom of the groove 2 are shaped like an arc at each edge of the support block 1. Because of this structure, it is possible to smoothly move each puzzle piece 4.Furthermore, according to the configuration of this embodiment, it can be composed of only the support block 1 and 24 puzzle pieces 4. The structure is extremely simple.

Modifications Note that the present invention is not limited to the configuration of the embodiment described above, but can also be configured as follows.

That is, the number of puzzle pieces 4 attached to each side of the cubic support block 1 is not limited to four, but can be n2 pieces (n is an integer of 2 or more) such as 9 pieces or 16 pieces. Further, the support block 1 is not limited to a cube, but can be a rectangular parallelepiped. In this case, the number of puzzle pieces 4 attached to two opposing sides of the rectangular parallelepiped is 4, and the number of puzzle pieces 4 attached to the remaining four sides is 2, etc. puzzle piece 4
The number is 2n or n2 (n is an integer of 1 or 2 or more) (
It can be rubbed.

Furthermore, there are various methods for forming the grooves 2 in the support block 1 in addition to the method of forming them using a synthetic resin material. That-
To give an example, first, as shown in FIG. Attach 6 pins in the center of the surface.

Next, as shown in Fig. 6, a second guide 8 is formed into a t-cube, which has an arc-shaped rectangular piece concentrically protruding from the inner surface of the arc-shaped rectangular piece with one side shorter in length than the arc-shaped rectangular piece. Take 122 pieces from the center of each edge (see Figure 7).
A third guide 9, which has a 1/8 spherical shell piece concentrically protruding from the inner surface of the 4th spherical shell piece with a shorter side length than the 4th spherical shell piece, is installed at each corner of the cube (each ridgeline of the cube (orthogonal corners) 8
Attach each piece.

According to this method, the groove 2 can be easily formed.

On the other hand, an engaging protrusion 5 provided on the inner surface of the puzzle piece 4
In order to smoothly slide within the groove 2 of the support block 1, both end surfaces of the fitting portion 6 may be formed into a convex spherical shape or a concave spherical surface. Moreover, the inner surface of the puzzle piece 4 can be made into a convex or concave spherical surface.

The groove 2 formed in the support block 1 is a substantially dovetail groove that tapers from the surface toward the bottom of the groove 2 as shown in FIG. 8, and the puzzle piece 4 fitted into the groove 2 is engaged. The projection 5 may have a tapered side surface as shown in FIGS. 8 and 9, and the tapered upper part may be curved from one lower corner to the other lower corner of the rectangular parallelepiped engaging projection 5. In addition, each puzzle piece 4 is placed in the groove 2 of the support block 1.
Lubricating oil may be injected or applied to ensure smooth sliding.

Although the outer surface of each puzzle piece 4 is colored in a heart shape, it is not noticeable. It may be numbers or a combination of numbers and colors. In addition, we add marks that can be recognized in the vertical direction, such as kanji characters with a certain relationship, such as ``Koitsuheicho'' and 子丑寅卯, or foreign characters with a certain relationship, such as ABCD, αβrδ, etc., to increase the fun of 3D puzzles. It is also possible.

Effects As detailed above, in the present invention, a plurality of grooves are formed in a hexahedral support block whose adjacent surfaces are orthogonal to each other, and which go around the surface of the block in columns and rows. The puzzle piece is formed into a curved shape and has a retaining protrusion that slidably fits into the groove of the support block, and the outer surface of the puzzle piece is formed into a square shape, and each side of the support block is formed into a square shape. By arranging 2n or n'' (n is an integer of 1 or 2 or more) puzzle pieces equal to the number of intersections adjacent to each other vertically and horizontally, you can enjoy complex puzzles, and the structure is simple. Moreover, it has an excellent effect of allowing each puzzle piece to be moved smoothly.
