Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a building block made of synthetic resin, which has both a cubic box-shaped building block and a rectangular parallelepiped box-shaped building block with a side ratio of 2:1 as the basic member. A toy block having two pairs of parallel side walls each of the same thickness and a bottom wall, the bottom wall being configured to define at least one protrusion, the protrusion The outer contour of the block corresponds to the contour defined by the side walls of the inner chamber of the box-shaped building block for the purpose of a connecting engagement.

BACKGROUND OF THE INVENTION Such a toy building block is known from German Utility Model No. 74 40 443.

This known building blocks toy was originally intended for preschool children to stack and use as walls. The fact that this toy building block has threaded bolts, nuts, axles and wheels provides other shape possibilities. For this purpose, holes are provided in the side walls of the box-shaped building blocks.

However, this configurability is limited when playing with the known toy building blocks because the alternating engagement or plug-in connection of the two block parts is constrained to its cubic or rectangular shape.

Problems to be Solved by the Invention Therefore, an object of the present invention is to enable a cube or rectangular parallelepiped box-shaped basic building block to be joined to a building block having a contour different from the shape of the edge of the basic member. It is in.

Means for Solving the Problem This problem is solved according to the invention by providing a rectangular block part having a rectangular interior contour and a cylindrical block part having a circular bottom wall molded integrally with the rectangular block part. The solution is to have at least one adapter block, the circular bottom wall of which is designed in the form of a circular projection.

This adapter block is used for inserting components with a cylindrical outer contour from a box-shaped basic building block of known type, for example another cylindrical part with a closed spherical cap or a cylindrical building block. connection to a cylindrical member having a bottom wall and a protrusion. The outer diameter of the cylindrical block part of this adapter block preferably corresponds to the edge length of the rectangular block part.

A central hole in the circular bottom wall of the adapter block allows it to be connected to other building blocks via threaded bolts. It is also possible to provide diametric holes in the transition plane between the rectangular block part and the cylindrical block part.

Embodiment A cubic basic building block 1 has a square bottom wall 2, as is known in the art.
A plate-shaped square protrusion 3 protrudes from the. The outer contour of this square projection 3 corresponds to the contour of the inner chamber of this basic building block 1 defined by the side walls. The contour of this interior chamber is indicated by a dashed line 4.

The adapter block 5 according to the invention has a lower rectangular block part 6 half the height of the basic building block 1, with a cubic interior contour 7. This inner chamber contour 7 corresponds to the outer contour of the square projection 3 of the basic building block 1 for the purpose of a connecting engagement.

A cylindrical block part 8 is integrally molded into the rectangular parallelepiped block part 6. The cylinder of this cylindrical block part 8 is closed by a circular bottom wall 9, which is designed to form a circular projection 10. Another basic building block (not shown) having a cylindrical interior contour can be connected onto this circular projection 10, so that this adapter block can be used to convert basic building blocks from cubes and rectangular parallelepipeds into cylindrical blocks. The shape and the connection of the cylindrical shape to the basic building blocks is guaranteed.

The circular bottom wall 9 and thus the circular protrusion 10 include:
A central hole 12 is provided.

The outer diameter of the cylindrical block part 8 corresponds to the length of the edge of the rectangular block part 6, so that in the transition plane between the two block parts 6, 8, the generatrix of the cylindrical block part 8 coincides with the rectangular block part 6. 4
located in the plane of two side walls. There are therefore four diametric holes 1 in the transition plane between the two block parts 6, 8.
2 (only two shown in the drawing) can be provided.
