Abstract

The invention relates to a polygonal, especially rectangular, parallelpiped building block made from transparent plastic and configured from two hollow halves (1) with facing parallel lateral edges. Coupling elements (3, 4, 5, 6) extend substantially perpendicularly from the peripheral flanges (1'') of said parts to connect the building block with adjacent blocks and the coupling elements on the opposite faces of any two structural members are interlockable. One attachment (3 or 5) with a groove (3' or 5') preferably open towards the visible surface (1') and running parallel with the visible surface edge and one attachment (4' or 6') with a nose preferably remote from the visible surface (1') and running parallel to the visible surface edge are provided as coupling elements at a mutual distance on each peripheral flange of each half-block. Said attachments (5, 6) are elastically deformable on two mutually facing sides of the building block and adjacent blocks can be engaged with a positive and non-positive fit by inserting the noses (6') into the grooves (5') on a narrow side of the block in the direction of the course of the groove on one side and by interlocking of the noses (4') and grooves (3') on the adjacent narrow side at the front.

Description

Building block made of translucent plastic

The invention relates to a polygonal, in particular quadrangular, parallelepipedal building block made of translucent plastic, which is composed of two hollow halves with mutually opposite parallel side edges, which, according to a plane running parallel to the visible surfaces of the building block, over circumferential flanges extending perpendicular to the visible surfaces are connected to one another, with coupling elements for connecting the building block to neighboring building blocks extending substantially perpendicularly from the peripheral flanges and the coupling elements being lockable with one another on two opposite sides of each building element. In a building block of this type known from EP-0 438 110 B1, for connecting the building block to laterally adjacent building blocks and for establishing a predetermined mutual distance, e.g. to form a translucent wall or the like., The coupling elements are designed as a connector, each with a tongue and a slot. The tongue or slot run inclined outwards from the peripheral flange, so that each building block for connection moves diagonally or obliquely against the other block and the like by means of a rubber hammer. must be engaged with this. This design has the disadvantage that the coupling elements cannot prevent a single building block from being knocked out of a composite perpendicular to it, i.e. Burglary protection is not guaranteed. In addition, the mutual connection of the building blocks is relatively difficult because a predetermined insertion angle must be maintained and considerable effort is required.

The present invention aims to avoid the disadvantages described and to design a building block of the type specified in the introduction with regard to the coupling elements in such a way that the mutual connection of the building blocks is simplified and a building block is prevented from being released from the assembly. It should be mentioned that building blocks are known from EP-0 368 479 in which knocking out of the composite is prevented, but separate coupling pieces are required for coupling the known building blocks, which must be used in aligned approaches of the building blocks. This represents a disadvantage in terms of production technology, costs and handling.

The building block according to the invention is characterized in that as coupling elements on each circumferential flange of each building block half, preferably close to the visible surface, with a distance from each other an approach with a preferably open to the visible surface, running parallel to the visible surface edge and an approach with a preferably from the visible surface turned away, parallel to the visible edge of the nose are provided, the approaches on two opposite sides of the building block are elastically deformable, and that neighboring building blocks on the one hand by pushing noses and grooves on a narrow side of the building block in the direction of the groove course and by the front Interlocking lugs and grooves on the adjacent narrow side can be positively and non-positively engaged.

With this design, the building blocks can not only be connected to one another in a simple manner, namely by pushing one into the other along the narrow side and snapping the narrow side at the front in the sliding direction into the narrow side of the adjacent block, but at the same time there is a risk of a single building block breaking out prevented from the composite because each building block is positively connected to the neighboring building blocks in three orthogonal directions. According to a preferred embodiment of the invention, the elastically deformable lugs are provided in cross-section with an oppositely sloping face and preferably also in opposite directions, while the other lugs are provided with straight faces and insides. The approaches are conveniently close to the corners of the building blocks. The invention is explained in more detail using an exemplary embodiment with reference to the drawings. Show it:

1 is a perspective view of a building block half; Fig. 2 is a side view of the building block in the direction of arrows P2-2 in Fig. 1;

Fig. 3 is a side view of the building block in the direction of arrows P3-3 in Fig. 1; 4 and 5, the coupling elements of the building block according to FIGS. 1 and 2 in detail, and

6 is a view of a composite with building blocks according to FIGS. 1-3.

1, one made of translucent plastic, e.g. Paralelepipedic hollow half 1 of a building block formed from polycarbonate or polymethyl methacrylate has a square visible surface 1 'and a peripheral flange 1 "extending from it towards the center of the building block. As indicated, the building block halves are, as indicated, along the peripheral edge of the flange 1 "welded together to form a building block.

Below a protruding circumferential edge of the visible surface 1 ', two coupling projections 3, 4 and 5, 6 extend substantially perpendicularly on each side of the building block half 1 from the circumferential flange 1 ". The approaches lie near the corners of the building block.

On each of two opposite sides of the building block, one 3 of the two coupling lugs has a groove 3 'which is open towards the visible surface 1' and runs parallel to the peripheral flange 1 ", and the other coupling lug 4 has a rib 4 'which also runs parallel to the peripheral flange 1". These parts can be seen in detail in FIG. 3. From this figure it can be seen that the end faces and the inside of both lugs 3, 4 are chamfered in opposite directions. On the other two opposite sides of the building block, the corresponding lugs 5, 6 are provided with straight faces, as can be seen in particular from FIG. 4.

As shown in FIG. 6, the building blocks can be positively connected to one another via the lugs 3, 4 and 5, 6, respectively the approaches also define the mutual spacing of the building blocks. The design according to the invention makes it possible to push adjacent building blocks along one of their narrow sides, which are provided with the lugs 5, 6, in the direction parallel to this with their coupling element grooves 5 ′ and lugs 6 ′, and at the same time to align the lugs 3, 4, respectively with elastic deformation over the beveled lugs and grooves 3 'click into each other at the end. In this way, the building blocks are positively and non-positively connected to each other and can no longer be knocked out of the compound individually.

It goes without saying that the exemplary embodiments explained above can be modified in various ways within the scope of the general inventive concept, in particular as regards the shape of the approaches and their relative position.
