Toy building board for building blocks with undercut Grooves and connecting pins

(New description for patent application P 14 73 386.9)

The invention relates to a device for receiving building blocks with undercut grooves and their cross-section adapted connecting pin certain toy plate made of plastic, which with it from their Edges of extending slots is provided.

There are building panels known in which special connecting elements such as for connection to building blocks Strips or the like. required are. Such fasteners are particularly useful for the playing child Younger age awkward to handle and it takes a certain skill to use such bars to be arranged in such a way that they do not protrude beyond the immediate connection points. They recover In addition, there is a risk that they will be lost or that they will even be injured when playing Evoke child.

Another known building board has openings into which connecting elements with undercuts are introduced. By twisting a building block

a bayonet-like form fit is obtained. However, this type of connection means that the the undercut forming part of the connecting element in the known toy plate in each case their back protrudes disturbing. A flat support surface of the building board on a table or a Any other surface can thereby be completely prevented.

The object of the invention is to design a toy building board of the specified type in such a way that that the building blocks described above without the aid of special building blocks or toy building panels separate fasteners are attached to the toy building board from different sides at the same time can. The attachment of the building blocks should also be possible if several similar building boards are used Forming a larger base plate lie directly next to each other.

According to the invention, this is achieved in that the respective slot width in the area of the plate surface is narrowed to form undercuts and that the slots in the area of the plate edges over their entire depth are expanded according to the largest cross-section of a connecting pin.

The undercut connecting pins of the building blocks are inserted from the edges of the plate into the slots and pushed to the desired location. on In this way, many building blocks can be placed in the desired location at a wide variety of locations

Arrange the toy building board. The connecting pins can be inserted through the slots that are widened towards the edge in these slots - also possible when several building panels are arranged close to one another are.

In the drawing, embodiments of the subject matter of the invention are shown.

Figure 1 shows a round disc as a toy building plate with a radially attached round rod. I. and building blocks,

Figure 2 shows a section II-II according to Figure 1,

FIG. 3, partially, the pane seen from the side in section, along the section line III-III according to Figure 1,

Figure 4 is a rectangular toy building plate seen from above,

FIG. 5 shows the toy building board, seen from the side, partially in section with inserted parts Building blocks and

Figure 6 the toy building plate seen from the front. ^

In Figure 1, a round disc 1 is shown, which has slots 2 extending from the outside to the inside, in the structure 3 or 4 round rods can be inserted as connecting or structural elements. The slot 2 has how Figure 3 shows - undercuts 2a on one or both sides, which make it possible in addition to the undercut pins 5 of the building blocks 3 from both sides, or in it

Waves 4 »cross pieces or similarly formed elements to take up frictionally. The incisions 6 are used for elastic tolerance compensation between the introduced Components and the slot-shaped hollow groove 212a.

In the case of the building board 7 according to FIGS. 4 to 6, the widened slots or hollow grooves 2, 2a are arranged on the outer edge of the two longitudinal sides, namely perpendicular to the central web 7a. In this way it is possible the blocks 3 from the outside w toward the middle 7a of the building to push plate 7, wherein the center part can be bridged by connection blocks 8 7a 'so that practically the entire surface of the building board 7, 7a for attaching can be used by components from both sides. This is very important, for example, in the construction of a car for the installation of walls on the upper side and for the installation of axles and wheels on the underside.

In the middle part 7a of the building board 7, tenons or Durohbrüohe 9 »10 can also be provided in a round or angular shape, which make it possible to insert additional building blocks 3 or rods 4. To connect the plates 7 at the end, a circumferential groove 11 or bores 11 'or bore 11 ^lf with a groove can also be provided. Thus, several building panels 7, 7a can also be firmly connected by means of single or double connections, both at the end and across the sides.

The building board therefore ensures that components can be picked up from different sides at the same time, and moreover the addition of further building boards.

The double groove offers a particular advantage if, as shown in FIG. 5, the building blocks ^{can be positioned exactly opposite one another at the end by means of appropriately shortened or shaped pins 5 1} , or the pins can slide past one another within the double groove.
