Toy building block system

In today's technical world, educationally valuable t '' _ .. Toys are becoming more and more important. Special technical jpie tool kits offer the opportunity to let children and young people grasp technical relationships in play and at the same time enable them to be more creative. To give shape to ideas.

The basic requirement for such a technical toy construction kit is a well thought-out toy, box system.

According to today's state of the art there are a variety of toy building block systems, but all suffer from certain deficiencies m. These deficiencies consist in the fact that the individual building blocks cannot be combined with one another as desired, or (and) that the connection of the individual building blocks with one another is too cumbersome or difficult to move, or (and) that the individual building blocks cannot be connected with one another has sufficient strength and si'-ti unintentionally loosens or shifts, or (and) that the building blocks lose their connectivity through repeated use, or (and) that the building blocks do not have a compact, closed, visually appealing shape.

The invention is based on the object of specifying a toy building block system, that avoids these deficiencies and thus meets the following requirements:

The modules must be combined with one another as required permit.

The building blocks must be sufficiently tight to one another can be connected, the connection must be easy to make and solve. The connection must be Ensure that the building blocks are fixed in all directions. The building blocks can be used even after frequent use Don't lose connectivity.

The building blocks should have a compact, closed shape and be inexpensive to manufacture.

This object is achieved according to the invention in that the individual modules be connected to each other by separate connecting elements. Tie blocks have round openings on all sides, which are in a certain Grid are arranged. The connection of the individual building blocks to one another is made by means of separate connecting filaments with resilient ones Snap hooks ("snap-in principle") that fit into the round openings in the building blocks click into place. The building blocks are hollow on the inside to allow the fasteners to snap into place.

In this way, any number of modules can be put together in Any combination that is only limited by the grid of round openings in the building blocks.

After a further development of the innovation, the module consists of two Parts that are plugged together ("snap-in principle") or glued together so that a completely closed but hollow building block is created.

After further training the innovation possesses the block towards the round openings have grooves of a depth which corresponds to half the flange thickness of the connecting elements, so that when two Building blocks whose outer contours sit on top of one another without any gaps.

According to another embodiment of the innovation, there are building blocks and connecting elements made of a thermoplastic material.

The house stone (figures la, Ib, lc, ld, Ie) consists of two different ones Components, namely the lower part 1 and the upper part 2 of the building block. The building block lower part 1 has two rectangular ones on each of the long sides Breakthroughs 3; the building block upper part 2 has four corresponding resilient latching hooks 4, which are arranged so that they are when joining the building block lower part 1 and upper part 2 of the building block in the rectangular openings 3 of the building block lower part 1 snap into place and a fixed connection between Building block lower part 1 and building block upper part? produce.

The block upper part 2 is in the outer contours and the "wall thickness the Building block lower part 1 adapted so that by joining the building block lower part 1 and building block upper part 2 a closed, symmetrical building block with the same wall thickness.

The resulting block has round openings 5 on all sides, the are arranged in a certain grid.

The connecting elements used to connect the individual modules to one another (Figures 2a, 2b) consist of two symmetrical resilient snap hooks 8, which are fixed to each other by a common flange 7 are connected. The connecting elements consist of a resilient elastic Material, such as a thermoplastic plastic.

A resilient snap hook is used to put two building blocks together a connecting element inserted up to the flange 7 in a round opening 5 of one building block, where it snaps into place; on the free second springy Snap hook 8 of this connecting element can now be used by the other module

712194016.11.72

be inserted with one of its round openings 5 and clicks onto the same way ("snap-in principle").

Have for easier insertion and locking of the fasteners their snap hooks 8 beveled front flanks 9 for easier loosening uui Vc bind 'iigbcIiJiiJCiitc' .ua ^ -. j rear flanks IQ of the snap hooks 8 also beveled.

The degree of bevel of the rear flanks 10 allows the strength or affect the releasability of the connection.

Along ⁰ and across the arrangement of the round openings 5, the blocks have grooves 6 of the same width as the flanges 7 of the connecting elements. The depth of the grooves 6 corresponds to half the flange thickness of the connecting elements. This ensures that plugged-together building blocks sit on top of one another with their outer contours without any gaps and are secured against unwanted rotation even when only one connecting element is used.

To release the components that have been plugged together, they are simply pulled apart or with a small screwdriver inserted into the Nirten R between the building blocks is pushed apart.

A mounting fork ( FIGS. 3a, 3b) is used to make it easier to push in and pull out the connecting elements.

The mounting fork consists of the lever 13, the fork-shaped flange 14, the tongue 11 and the reinforcing ribs 12. The thickness of the fork-shaped flange 14 corresponds to the wall thickness of the building blocks. The width of the fork opening of the fork-shaped flange 14 corresponds to the diameter of the ruiiden Breakthroughs 5 of the building blocks.

To be pressed into a building block, a connecting element is attached to the mounting fork postponed that the flange 7 of the connecting element rests against the underside of the fork-shaped flange 14 of the mounting fork and the Tongue 11 of the mounting fork into the opening of the snap hook 8 of the connecting element protrudes. The mounting fork is dimensioned so that the connecting element is slightly clamped in the mounting fork, so that falling out during assembly is definitely prevented. The tongue 11 protruding into the opening of the snap hook 8 prevents compression same.

To pull a connecting element out of a block, the Monday eg from el scheduled in the same way. After pulling it out in this way the connecting element can easily be pushed off the mounting fork.

Due to its versatile combination options, its also after frequent The toy building block system is well suited to the use of exact connection mechanics, its compact and yet inexpensive to manufacture shape demands made on educationally valuable technical toys these days meet.
