Abstract
The system consists of a board with sockets and an assortment of tetrahedral pegs having a regular obverse face and a reverse side in the form of a triangular shank that inserts to a matching fit in one of the sockets. When the pegs are inserted into the board or first element the adjacent faces of the pegs make contact so that no gaps exist between adjoining edges. Each of the faces, or a part of each face, if divided into more than one field, is uniformly tinted in one of a set of repeatable colors or polychrome or monochrome shadings.

Description
Background of the Invention
The invention relates to a system of elements used in creating graphic compositions.
The prior art embraces graphics composition systems consisting of a perforated surface, or board, and a plurality of pins, or pegs, insertable in the holes of the board.
The holes are set close to one another, positioned in such a way that the heads of the inserted pegs are brought into contact one with another.
Thus, using pegs with heads in a variety of colors, it becomes possible to insert the pegs selectively into the holes by their shanks, in such a way that the heads create a graphic composition resembling mosaic.
The main drawback with such a system of elements is that the surface of a finished composition appears irregular and lacks continuity.
Accordingly, the object of the present invention is to provide a system unaffected by the drawback in question.
Summary of the Invention
The stated object is realized with a system of elements for the creation of graphic compositions according to the invention.
Such a system comprises a first element, or board, affording sockets in which to insert the matching shanks of second elements, each having a regular polygonal flat face disposed normal to the axis of the shank. The distance between adjacent sockets is such that the polygonal faces of the inserted second elements lie in full contact one with the next by way of their corresponding respective sides, with no gaps remaining.
Brief Description of the Drawings
The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which:
FIGS. 1 and 2 show a plan and a side elevation, respectively, of certain elements of the system according to the invention;
FIG. 3 shows a perspective of one of the elements illustrated in FIGS. 1 and 2;
FIG. 4 illustrates a possible graphic composition obtainable with the system of elements according to the invention;
FIG. 5 is the perspective of a further element of the system disclosed.
Description of the Preferred Embodiments
With reference to FIG. 1, the system of elements according to the invention consists essentially in a first element, or board 1, and a plurality of second elements 3.
The second elements 3 are embodied each with one flat face 4 of regular polygonal shape, and on the reverse of the flat face, a shank 5 insertable in one of a plurality of sockets 2 formed in the top surface of the board 1.
The shank 5 might be cylindrical in embodiment. Alternatively, the cross section of the shank might be geometrically similar to the flat face 4, and of proportionately reduced dimensions, needless to say; for example, the element 3 might be embodied as a pyramid the base of which coincides with the flat face 4.
In a preferred embodiment of the invention, each element 3 appears as a regular tetrahedron, the flat face 4 coinciding with any one of the four tetrahedral faces, and the shank 5 coinciding with the tetrahedral solid in its entirety.
The flat face 4 is uniformly tinted in one of a selected range of colors, or poly- or monochrome shadings, and might be divided up into two or more fields of which the dimensions of the sides that coincide with the sides of the relative flat face 4 may be either equal to or sub-multiples of the dimensions of those sides.
With reference in particular to FIGS. 1 and 2, the board 1 affords a plurality of sockets 2 exhibiting equilateral triangular sections, and a plurality of second elements 3 embodied as regular tetrahedrons.
The adjacent edges 6 of adjoining sockets 2 are disposed parallel and set apart one from the other at a perpendicular distance equal to twice the distance by which the corresponding side of a flat face 4 projects beyond the edge when the relative second element is inserted in the socket (FIG. 2).
Thus, the flat faces 4 of the second elements 3 are brought fully into contact one with the next by way of their adjoining sides, in such a way that no gaps remain between them.
In the example of FIG. 3, which shows an element 3 of regular tetrahedral embodiment in accordance with the foregoing description, each face 4 is divided into two fields by a straight line either lying parallel to one side and intersecting the two remaining sides at mid-point, or bisecting one of the angles.
Each field of the flat face 4 divided in this way is uniformly colored or shaded as aforementioned, and the coloring or shading of the two fields is dissimilar.
It will be clear enough that a regular tetrahedral shape as disclosed provides considerable savings in material, since each element 3 has four different flat faces 4, any one of which can be used in the creation of a selected graphic composition.
FIG. 5 illustrates an alternative embodiment of the invention, in which the second elements 3 might be cubes insertable in the single recess of a board 1, or otherwise supported, offered one to the next in full frontal contact with no gaps remaining, and colored in the manner described above. In this type of embodiment, multicolored faces may be divided by one of the two diagonals, or a line parallel thereto, or by a line parallel with one side.
