Two- and three-dimensional folding object

The invention relates to a two- and three-dimensional folding object made of parts connected to one another in a hinge-like manner. This object is two-dimensional in its basic state and can be folded into various three-dimensional structures.

The possible applications exist particularly in the toy sector, as special packaging forms and as advertising media.

The task was to expand the objects known in these areas with new variations and to further develop possibilities for special areas of application.

According to the invention, the two- and three-dimensional folding object consists of hinged parts

- from 2 x 6 equilateral triangles,

- which in the basic state are arranged in two equilateral hexagons lying on top of each other and

- the triangles are hinged together 5 times and not connected to each other in one case,

- whereby the two-layer hexagons are hinged together on 3 adjacent outer sides and

- the edges of the triangles not connected to each other in the equilateral hexagon are directly connected to the three pairs of triangles on the outside.

The size of the respective triangles depends on the area of application. Any side edge length is conceivable, preferably in the range between 5 cm and 100 cm.

The surface of the triangles can be smooth or structured. The triangles can be alternately black or white or any color.

A hinged connection means that the triangles that are adjacent to one another can be folded over at an angle of up to 360°. In principle, all folding connection techniques that allow this can be used, such as tear-resistant foil, film, textile or hinged constructions.

Various materials and constructions with sufficient rigidity for the application are suitable for the triangular elements, e.g. plastics, foam material, cardboard or stiff paper. Easy bendability is desirable.

Triangles made of rigid plastic, which are hinged together with thin plastic elements, are particularly useful for this purpose.

Another preferred form of production consists in using a tear-resistant carrier material, e.g. textile fabric, as the base body, which is connected on both sides to the equilateral triangles made of rigid material.

The triangles can also be made of different materials, e.g. plastic or cardboard as the inner material and foil, fabric or felt for the surface. If the material for the surface is made of thin, foldable material, it can also take on the function of the hinge at the connection points.

The folding object according to the invention in its various states is described by way of example by the following figures:

Figure 1 Ground state

Figure 2 a variant in the unfolded state

Figure 3 a and b possible intermediates in the production

Figure 4 a to d Folding objects in the form of double pyramids

Figure 5 a to h Folding objects in the form of possible folding variants

The key figures mean

1 equilateral triangles

2 equilateral hexagons

3 hinge-like connections

4 unconnected edges

5 edges that are free during production but then have to be connected

Fig. 1 shows the folded object in the form of two equilateral hexagons lying on top of each other. In each layer, the triangles are connected like hinges at points 3, and at point 4 the edges are not connected (the hexagon is cut in a way). There is also a connection at the three outer edges 3.

Fig. 2 shows the folding object in a possible perspective form in the unfolded state.

Fig. 3 demonstrates two possibilities for manufacturing a double hexagon. This double hexagon is punched out of plastic, for example, whereby the manufacturing process is designed so that the plastic is thin and foldable at the points where the hinge-like connection is to be. Finally, the 2 x 2 edges 5 are connected to one another.

Fig. 3 a shows the variant in which the unconnected edges lie on top of each other in the respective hexagon corners after completion. This leads to the folded objects as shown in Fig. 1 and Fig. 2.

According to Fig. 3 b, the unconnected edges in the respective hexagons are arranged opposite each other.

Known technologies can be used to produce two- and three-dimensional folded objects, which essentially depend on the type of material used.

With the two- and three-dimensional folding object, an extraordinary number of different three-dimensional structures can be created, some of which are also stable in themselves. Some examples show the variants in Fig. 4 with all the double pyramids that can be folded from equilateral triangles. With the appropriate design, they can also be represented by folding in different color combinations.

Further design variants are shown in Fig. 5. Due to the numerous intermediate shapes when folding, the design variations are almost unlimited.

The preferred area of application is in the toy sector. The two- and three-dimensional folding object can be a folding object for the hands, for example. This can be used for individual and group games. Working with the object trains spatial imagination and sensorimotor skills in particular.

The preferred triangle edge lengths are 5, 8 or 14 cm, but all other dimensions are also suitable. In a larger version, the object can also be used to form three-dimensional bodies that children can crawl into, provided the appropriate material is chosen.

In a version where the triangles are filled with air or Styrofoam, for example, it can also serve as a floating toy on the water.

The two- and three-dimensional folding objects are also used in the packaging industry for special areas, especially as inserts with original spatial shapes.

The different versions of the two- and
three-dimensional folding objects, e.g. decoration for the desk,
Folded card.

The different colour designs also depend on the respective area of application and can include images, symbols (letters, numbers), company logos, etc.
