Abstract

The utility model relates to an octahedral magic cube. A regular octahedron is composed of eight rhombic corner blocks, twelve trapezoidal edge blocks and eight triangular facet cores; each surface of the regular octahedron is coated with different colors or patterns. When the rhombic corner blocks rotate, the trapezoid edge blocks and the triangular facet cores can correspondingly be driven to rotate together, and thus various kinds of color combination can be obtained. Compared with the Rubik magic cube, the utility model has a low difficulty gradient of aligning one surface to two surfaces, which can arouse players' interest, and the difficulty gradient of aligning eight surfaces is not lower than that of the Rubik magic cube.

Description

Octahedra magic square

The utility model belongs to a kind of puzzle of individual's pastime usefulness, specifically a kind of magic square.

The regular hexahedron magic square of Hungary professor Lu Bike invention has six faces, and each face is made up of 9 little square blocks, and the blockage on each face can rotate jointly around this face center, thereby produces different combinations.The player changes into same color to train the intellect with some faces after changeing magic square disorderly again.For Rubik Magic Cube, player's be easy to align face of magic square, but the color of two faces that will align simultaneously, just be difficult to accomplish, that is to say from too big to the difficulty span of two faces of alignment a homogeneous face, this has just hit player's interest, and Rubik Magic Cube just loses its reliss to the player.And other are round with type toy such as evil spirit, magic ball is too simple, and the player is easier to find rule, and all patterns that align can't further be developed player's intelligence.

It is a kind of handsome in appearance that the purpose of this utility model is to provide, progressive to a plurality of difficulty to a homogeneous face, the octahedra magic square of interesting strong intelligence.

The technical solution of the utility model is as follows:

Octahedra magic square of the present utility model, the center is the rotating shaft (1) that the six roots of sensation can rotate freely, point to six summits of regular octahedron separately, each fixes the hornblock (2) of a taper rhombus summit of each rotating shaft (1), between per two hornblocks (2), snap in a trapezoidal rib piece (3), snap in 12 rib pieces (3) altogether, in the middle of per three rib pieces (3), snap in a triangle center of area (4), snap in 8 triangle center of areas (4) altogether, constitute a regular octahedron magic square.

The center of octahedra magic square of the present utility model can be a little regular cube (B), and the center of each face of little regular cube (B) connects a rotating shaft free to rotate (1).The spring of can packing in each turning cylinder (1), the friction when rotating between rotating shaft (1) and middle body-centred cube to reduce.

Eight faces of octahedra magic square of the present utility model can topped different color or pattern.

Effect of the present invention is:

1. reduced the difficulty upstroke slope of recreation.Octahedra every of magic square has only seven color lumps (Rubik Magic Cube has 9 color lumps), it has reduced the difficulty to a homogeneous face effectively, therefore with comparalive ease can be to a homogeneous face, through certain effort two faces that can align, and then advance to the multiaspect of aliging more, excite constantly enterprising interest of player.

2. having sufficiently high intelligence height to hold the player climbs.It is 3.24 * 10 that octahedra magic square changes number ¹⁹, and the variation number of Rubik Magic Cube is 4.325 * 10 ¹⁹, both have the identical order of magnitude, so the octahedra magic square of the utility model has enough intellectual development height.

3. octahedra each face of magic square has rhombus, trapezoidal, triangle color lump, is full of variety, and is more attractive in appearance than Rubik Magic Cube, have more feeling of freshness so more attractive.

Description of drawings:

Fig. 1 is the three-view diagram of rhombus hornblock (2);

Fig. 2 is the three-view diagram of trapezoidal rib piece (3);

The a of Fig. 3, b, c figure are the three-view diagram of the triangle center of area (4), and d figure is the perspective view of main of triangle center of area coupling part;

Fig. 4 is the profile and the vertical view thereof that are connected in the rotating shaft (1) on the little regular cube B;

Fig. 5 is the stereo appearance figure of octahedra magic square.

Embodiment:

One little regular cube (B), center at each face of little regular cube (B), be connected with a rotating shaft (1), rotating shaft (1) is formed (as Fig. 4) by T oblique crank Z (A), bolt (C) and the spring of a hollow, bolt (C) passes T oblique crank Z (A) and spring is fixed on the little regular cube (B), spring jack-up T oblique crank Z (A), to reduce the friction between T oblique crank Z (A) and little regular cube (B), rotating shaft (1) can rotate freely.Fix a taper rhombus hornblock (2) on the top of each rotating shaft (1), snap in the trapezoidal rib piece (3) and the triangle center of area (4) on every side at each rhombus hornblock (2), constitute a regular octahedron, coat different colors at eight faces of regular octahedron, octahedra magic square.

When a rhombus hornblock (2) that rotates octahedra magic square just drives four trapezoidal rib pieces (3) and four triangle center of areas (4) are rotated together,, so can not come off when rotating owing to its syndeton such as Rubik Magic Cube.Rotate each rhombus hornblock (2) successively and just can obtain the combination of different color.

Claims

1. octahedra magic square, the center is the rotating shaft (1) that the six roots of sensation can rotate freely, point to six summits of regular octahedron separately, it is characterized in that each rotating shaft (1) the summit each fix the rhombus hornblock (2) of a taper, between per two rhombus hornblocks (2), snap in a trapezoidal shuttle piece (3), snap in 12 trapezoidal shuttle pieces (3) altogether, snap in a triangle center of area (4) in the middle of per three shuttle pieces (3), snap in 8 triangle center of areas (4) altogether, constitute a regular octahedron magic square.

2. octahedra magic square according to claim 1 is characterized in that the center can be a little regular cube, and the center of each face of little regular cube connects a rotating shaft free to rotate (1).

3. octahedra magic square according to claim 1 and 2 is characterized in that the spring of can packing in each rotating shaft (1), the friction when rotating to reduce between rotating shaft (1) and middle body-centred cube.
