FORM STONE

The invention relates to a shaped brick

(a) which has four stone corners and four contact surfaces, namely one contact surface between two adjacent stone corners,

(b) where there are contact surface areas which - viewed from above - deviate from the direction of the relevant

Connecting lines between two adjacent stone corners run differently.

The invention is based on the object of creating a shaped stone with a laying aid for maintaining a uniform joint spacing and at the same time for achieving improved positional fixation relative to adjacently laid shaped stones.

To achieve this object, the molded block is characterized according to the invention in that

(c) that spacer elements are provided on the contact surface areas according to feature (b) to determine a joint spacing to adjacently laid stones,

(d) some of these spacer elements are designed as spacer element pairs each for receiving a spacer element of an adjacent

laid shaped stone to achieve a locking effect that prevents displacement.

Formed bricks with spacer elements (which are often referred to as "spacer studs" for simplicity) on the contact surfaces, in order to be able to easily lay the formed bricks on already laid formed bricks while maintaining a uniform joint spacing, are known per se. The formed brick according to the invention has gone a significant step further because pairs of spacer elements accommodate spacer elements of adjacently laid formed bricks (which, among other things, perfects the correctness of the laying) and because the spacer elements or pairs of spacer elements are at least partially attached to such contact surface areas.

are provided which - seen in plan view - run deviating from the direction of the relevant connecting line between two adjacent stone corners. Shaped stones with contact surface areas running in this way interlock with adjacently laid shaped stones anyway. The interaction according to the invention between receiving spacer element pairs and spacer elements received there creates a new type of positional fixation against displacement of the stones in the direction of the course of the contact surface areas according to feature (b).

Preferred developments of the invention are specified in claims 2 to 9.

In the further development according to claim 2, a spacer element on the opposite contact surface of the shaped block corresponds to a pair of spacer elements, so that an identical shaped block can be easily placed and the displacement-preventing locking effect between a pair of spacer elements and a spacer element is achieved.

However, as stated in claim 3, one or more spacer elements can also be provided, to which no pair of spacer elements corresponds on the opposite contact surface of the shaped block. These spacer elements can serve as an additional laying aid without their own locking effect.

Claims 4 to 8 provide more concrete possibilities for the arrangement of spacer elements and spacer element pairs.

In the further development according to claim 9, spacer elements and pairs of spacer elements are provided on contact surface areas which - seen in plan view - are inclined relative to the relevant connecting line between two adjacent stone corners. This is a preferred form of the "course that deviates from the direction of the relevant connecting line between two adjacent stone corners". Other forms of this deviating course are possible,

especially rounded gradient, wavy gradient and much more.

The invention is explained in more detail below using drawings showing exemplary embodiments. It shows:

Fig. 1 an arrangement of four forms laid next to each other

stones of a first embodiment in plan view;

Fig. 2 another arrangement of four adjacent

Shaped bricks of the first embodiment in plan view;

Fig. 3 a single shaped brick of the second embodiment in

Top view.

The four shaped stones 1 shown in Fig. 1 are identical to one another. Each shaped stone 1 has four stone corners 2, with a contact surface 3 extending between two adjacent stone corners 2.

Each contact surface 3 runs in a zigzag pattern when viewed from above. The connecting lines 4 of the four stone corners 2 are shown in dashed lines. These connecting lines 4 form a rectangle that is twice as long as it is wide.

On the two longer stone sides, the contact surfaces 4 consist of five contact surface areas 5, which are inclined relative to the relevant connecting line 4. On the two shorter stone sides there are three inclined contact surface areas 5 each.

On the upper, longer stone side in Fig. 1, a pair of spacers 6 and a (single) spacer 7 are provided in the middle contact surface area 5, and also a (single) spacer 7 in the middle of the right-hand contact surface area. On the lower, longer stone side in Fig. 1, a pair of spacers 6 and a (single) spacer 7 are provided in the middle contact surface area, but in reverse to the upper stone side, i.e. the pair of spacers 6 on the left and the spacer 7 on the right; also a (single) spacer 7 is provided in the left-hand contact surface area. If you draw the longitudinal bisector line 8 of the stone,

then the upper pair of spacers 6 (strictly speaking its middle) can be connected to the corresponding spacer 7 on the lower side of the stone by a connecting line 9 that runs at right angles to the bisecting line 8. The same applies to the lower pair of spacers 6 and a corresponding spacer 7 on the upper side of the stone.

On the left, shorter stone side in Fig. 1, a (single) spacer element 7 is provided in the middle of the uppermost contact surface area 5. On the right, shorter stone side in Fig. 1, a (single) spacer element 7 is provided in the middle of the lowermost contact surface area 5.

Fig. 1 shows the four shaped stones 1 in the so-called stretcher bond. Each pair of spacers 6 holds a (single) spacer 7 of an adjacent stone 1 in a form-fitting manner. Without this form-fitting engagement, a stone 1 could be displaced relative to an adjacent stone 1 in the direction of the inclination of a considered contact surface area 5. In this respect, the spacers 7 and pairs of spacers 6 create an improved positional fixation of the stones 1 relative to one another.

It can also be seen that those (individual) spacer elements 7 that have not been accommodated by a pair of spacer elements 6 contribute to maintaining a uniform joint spacing between the laid stones 1.

The shaped stones 1 shown in Fig. 2 are identical to the shaped stones 1 shown in Fig. 1, but now laid in a so-called herringbone pattern. It can be seen that with this laying pattern, the spacer element pairs 6 each accommodate a spacer element 7 of a neighboring stone 1. Although some of the stones 1 are rotated by 90° relative to other stones 1, mutual placement with engagement between spacer element pairs 6 and spacer elements 7 is possible without any problem.

The embodiment of a shaped stone 1 according to the invention shown in Fig. 3 differs from the shaped stone 1 shown in Fig. 1 and 2 only in that four additional pairs of spacer elements 6 are provided, namely one on the upper, longer stone side in the very left contact surface area 5, one on the lower, longer stone side in the very right contact surface area 5, one on the left, shorter stone side in the lowest contact surface area 5, and one on the right, shorter stone side in the upper contact surface area 5. This provision of pairs of spacer elements 6 and (individual) spacer elements 7 creates a perfected positional fixation with adjacently laid shaped stones 1 at numerous fixation points. Laying in a stretcher bond according to Fig. 1 or in a herringbone bond according to Fig. 2 or even long stone side against long stone side without offset are possible.

In the drawings it can also be seen that the stones have a bevel 10 at the transition between the drawn stone top and the contact surfaces 3. The spacer elements 7 and the spacer element pairs 6 are preferably bead-shaped, but could also be triangular or trapezoidal, for example, in plan view; they preferably extend in a straight line in the vertical direction. The spacer elements 7 and the spacer element pairs 6 preferably take up almost the entire height of the contour surfaces 3, but preferably end a certain distance below the bevel 10.

It is emphasized that - in contrast to the illustrated examples - not all contact surface areas 5 necessarily have to run from the connecting line 4 between two adjacent stone corners 2. There can also be individual contact surface areas 5 that run on the connecting line 4 or parallel to it. A contact surface area 5 is - seen from above - a partial length of the complete relevant contact surface 3.
