Description

M / 21 202 - 2 -

The innovation concerns a 50-surface, spherical one Body with two surfaces that are antipodally assigned to each other.

The regular arrangement of flat surface sections on a spherical surface has been known for a long time Problem. Only certain combinations of surfaces and numbers of surfaces can be arranged on a spherical surface in such a way that everyone a flat surface section can also be assigned a flat antipodal surface section.

In the case of the body according to the invention, there are 50 flat surface sections so arranged on a spherical surface that in each case one of the flat surface sections is on top. With a preferred Embodiment according to the invention are the 50 surface sections divided into 30 squares, 12 diamonds and 8 triangles. The individual surfaces are arranged on the spherical surface in such a way that that every 4 squares each have one side in common with a central square. Preferably the order the central square arranged four squares each one side with a triangle and two opposite each other Sides with two diamonds in common.

The individual surface sections can be of different colors, they can also be slightly raised, relief-like from the spherical surface be worked out. According to another embodiment, the edges of the surfaces can also be something in relief be increased compared to the surfaces themselves, which also represents a possibility of improving the positional stability of the ball. In addition, by slightly increasing the surfaces themselves or the edges of the surfaces, the surface on top can be made lighter be identified.

In the preferred embodiment described above, in which the 50 surface sections of the sphere according to the invention are divided into 30 squares, 12 rhombuses and 8 triangles, these can 50 surface sections can also be designed so that on each surface section there is a slightly increased circular area of same diameter is located. This embodiment has the Advantage that no surface section is disadvantaged compared to another due to surface shape or surface size.

The individual surface sections can have different labels, Bear symbols or numbers. In a preferred embodiment of the 50 surface sections are of the invention Body 49 is labeled with the numbers 1 to 49 and the 50th area bears the irgeriäeUn joker symbol. In this embodiment the ball is particularly suitable for determining lottery numbers.

The body according to the invention can be made of various materials, are preferably made of plastic. It will preferably be produced in one piece or in two equal halves, in the latter case, the two halves can be plugged together or glued together.

In the preferred embodiment outlined above, in which the 50 areas are divided into 30 squares, 12 rhombuses and 8 triangles, the body according to the invention can be made up of 6 elements of the type shown in Figures 2 to 4,; by placing these 6 elements on the 6 faces / of a central j Appropriate size cube attached. An on remains at the points where three such elements adjoin one another triangular space on the surface, which can be completely or partially filled with appropriately shaped inserts. It is sufficient also to close the surface of the ball, which is not closed at this point, with a corresponding plastic triangle. The aforementioned elements of FIGS. 2 to 4 can have conventional non-releasable or releasable plug connections

which they can be attached to the central cube. The same applies to the 8 triangles for closing the triangular areas. When using detachable connectors, the ball can therefore be used as an assemblable puzzle which combines the 6 large, octagonal elements with the 8 triangles in a very specific way can be. The combinations can be determined by the numbers on the individual faces or the colors of the faces or be varied.

The innovation is to be explained in more detail using the following description of the figures.

Figure 1 shows a body according to the invention in plan view in half-perspective representation.

Figure 2 shows an element for assembling one according to the invention Body whose surface is divided into 30 squares, 12 diamonds and 8 triangles.

Figure 3 shows a section along the line II-II of Figure 2 and

Figure 4 shows a section along the line I-I of the figure

From Figure 1 it can be seen that the surface of an inventive Body in 8 triangles, 12 rhombuses (in Figure 1, the rhombuses are simplified as squares on the corner) and 6 elements, each of which has 5 centrosymmetrically arranged squares of equal size can.

In FIGS. 2 to 4, one of the aforementioned elements is the square, which is arranged centrosymmetrically Has surfaces shown. Figure 2 shows a planar projection of such an element. In reality are the four outer squares arranged centrosymmetrically around the central square at a certain angle inclined to the plane of the central square, as shown, for example, in the sectional images of FIGS. 3 and 4. at this element is an octagonal element as a whole, as FIG. 2 shows. The slope of the element forming areas to the area of the central square, depends on the respective diameter of the desired body.

With a body diameter of about 4.5 cm, the squares have

2 a side length of about 1 cm, so that .-. \ "\ 1 cm large flat lying areas result, which is sufficient for a stable position. The body can of course also be larger or be made smaller.

FIG. 5 shows how the 6 elements of FIG. 2 make up one according to the invention 50-surface spherical bodies can be put together, if one sees this body as a separable one Puzzle designed. In this case, the 6 elements of FIG. 2 are connected with plug connections on the 6 surfaces of a central Cube attached. There then remain 8 open triangles on the surface, which are closed by appropriate inserts can be.

If the body should not be able to be dismantled, it is best made in one piece from a thermoplastic or from a foam plastic, by in the latter case one foams the corresponding shape.
