INSTALLATION SYSTEM FOR VISIBLE OR INVISIBLE FASTENING OF SURFACE PANELS ON SUB-CONSTRUCTIONS

The invention describes a laying system for visible or invisible fastening of planar panels, such as patio areas, pool surrounds, wall coverings or floors on a suitable substructure. The cladding is secured by boards, which are also referred to as planks or floorboards on a corresponding substructure and forms substantially the visible area of the cladding.

Laying systems where boards are mounted on a substructure are known in the state of Teohnik. A disadvantage of these solutions is that the laying is usually done in batches, so that board must be mounted on a board and it is not possible to lay an entire terrace and then attach in one operation. This would save a great deal of time since it is not necessary to change different tools such as a drill and cordless screwdriver for different operations and to carry them from substructure to substructure.

In addition to saving time, a loosely laid cladding surface would also make work easier, since the end position of the boards can be determined in a conventional operation only when laying and screwing. This can lead to a necessary post-treatment by cutting or planing the boards, which means increased work, since already fixed boards must be removed again. It would be desirable to identify inequalities before fixing the boards and to compensate easily by an intelligent installation system. Daduroh would be a costly removal of the already anchored boards no longer necessary.

Another Naohteil the board-wise attachment is that a precisely rectilinear screw can not or only very difficult to achieve, because only a short area is screwed. If the screw position of all boards can be determined in the already laid state, an ideal screw pattern results with visible screw connection, ie all screws are in line.

Often it is also problematic that in the direct attachment of boards on the substructure in the intermediate area moisture and dirt can accumulate, which leads to rapid degradation, the rotting of the wood. Known systems attach little importance to dissipate water and dirt as possible and in particular to avoid a damming light.

The aim of the invention is therefore to develop a laying system, which serves for the visible or invisible attachment of boards as cladding element, which overcomes the disadvantages listed and allows positionally fixed to move the entire panel, without the individual boards already secure and fixation the boards can be made in a second operation for the entire installation surface.

Such a laying system is described in claim 1 and the following dependent claims and exemplified in Figures 1 to 6.

[0009] FIG. 1 shows an embodiment variant of a board (10). [0010] FIG. 2 shows an exemplary shim element (20). [0011] FIG. 3 shows a fastening element (30) for invisible fastening with a screw (40) [0012 Figure 4 shows the fastener (30) in top view Figure 5 shows a laying structure with visible attachment Figure 6 shows a structure with invisible attachment The following reference numerals are used: 10 ... board 11 ..

Recess 27 ... drainage groove 28 ... marking 30 ... fastening element 31 ... arms of the fastening element 32 ... elevation 33 ... outer surface 40 ... screw 50 ... substructure [0016] The laying system consists of Unterlegelementen (20), which can be connected to each other at different distances. The connection is made by a positive connection in the form of a toothing. In this case, the toothing with a toothed mandrel (21) and attached to the other end of the toothed fork (22), which mesh with each other are realized. By the connection by means of a toothing a different distance from each other is possible by different locking positions. On the one hand, this helps to adapt the lower elements (20) for different board widths and, on the other hand, to use them for different joint widths.

The shims (20) have in addition to the toothed mandrel (21) and the toothed fork (22), at least one dome (23) which at least one inserted into the board (10) groove (11) enters into a positive connection and thus a slip-proof positioning of the boards (10) on the substructure (50) allowed without screwing the boards (10).

Optionally, the shims (20) may also be equipped with one or more mounting options on the ground. For this purpose, a fastening hole (25) in the shim (20) is preferred, by means of which any or individual shims (20) can be fastened to the substructure (50) by means of screws or nails.

The lower elements (20) can also in different areas where a subsequent screwing of the boards (10), with an opening (26) are provided so that the screw with the board (10) is fixed directly in the substructure (50) is introduced.

Furthermore, at least one drainage notch (27) on the underside of the shim (20) can be located so that waterlogging and condensation can drain.

The lower elements (20) are preferably made of plastic, with filling or reinforcing material reinforced plastic, wood fiber reinforced plastic (WPG), but also made of aluminum or other metals.

Boards (10) are preferably wooden boards, all woods are suitable and the installation system is not limited to a particular species.

But the boards (10) may also be so-called WPC boards made of wood fiber reinforced plastic, or be made of plastic, metal, in particular light metal, for example aluminum in each case as solid profile, or hollow chamber profile.

The board (10) is executed with at least one, preferably two or more grooves (11) on the bottom and optionally with at least one groove (12) in the side surface.

In addition to the positive connection to the lower element (20) and the optional fastening element, the grooves (11) in the board (10) also help to reduce the residual stresses in the wood and thereby minimize the tendency of the boards (10) to become distorted.

On the substructure (50) on which the terrace, the swimming pool border, the floor or the wall paneling is to be built, for the positioning of the boards (10), the shims (20) are applied. These (20) can be easily placed or partially, or even completely connected to the substructure (50) by screws or nails. This is especially desirable for large installation surfaces or wall coverings in order to achieve a better stability of the elements (20) to each other.

As at the lower element (20) at least one dome (23) is applied, which enters into a positive connection with the groove (11) in the board (10), the board (10) is positioned in the transverse direction.

The shims (20) for a plurality of boards (10) are connected to each other, so that the gap width between the individual boards (10) is determined by the shims (20). For different board widths and different desired joint widths here is an adjustment by a toothed connection.

Two elements (20) can be connected by the two gears with a different distance, wherein the spacing is dependent on the execution of the tooth geometry. Preferably, an adjustment between 0.5 and 5.0 mm is selected in the toothing. Overall, both the toothed mandrel (21), as well as the toothed fork (22) has a length of 20 to 60 mm, so that an adjustment range of 0 to about 100mm is formed because the two elements must interlock.

The design of the toothing is preferably such that the toothing is available in both directions. This means that both the toothed mandrel (21) can be inserted from above into the toothed fork (22), as well as the toothed fork (22) can be moved from above over the toothed mandrel (21).

Likewise, markings (28) may preferably be provided on the toothed fork (22), which make the position of the toothed mandrel (21) easily recognizable. These may be lines, numbers, letters or other markings as a relief in the molded part (20), or also subsequently printed markings. In the case of subsequent printing, a color code is particularly suitable for determining the position. This means that different colors indicate the different position for the toothed mandrel (21).

The tooth geometry can have different shapes, so in particular wave-shaped, triangular, rectangular, trapezoidal geometries are possible.

After laying the entire installation surface, this can be committed, individual improvement work regarding gap dimensions, etc. can still be corrected relatively easily and the markings made for attachment. In this case, an exact line for the fasteners are drawn, which is then drilled and screwed or nailed. By marking the entire laying surface in the already laid and positioned state, an exactly rectilinear screwing can be created, which is advantageous for visual reasons.

Due to the patency of respective steps and the laying time is reduced, which is also advantageous. This reduction in working hours results from the fact that the required tools are not used separately for each board (10) and are put away again, but the entire installation surface is processed at once.

This can be worked out more accurately and also saves time, instead of screwing board {^ 0) for board already during installation, but this would be technically possible with this system.

If an invisible attachment of the boards (10) is desired, the boards (10) must also have the lateral groove (12).

In this case, a fastener (30) is introduced with the narrow side into the joint between the boards (10) and when fastened with a screw (40), the arms (31) of the fastener (30) rotate initially with until they are held bounded by the groove depth (12) in the board (10) and the screw (40) is screwed for fixing until the arms (31) apply a pressing force on the groove (12) on the board (10) and this to the substructure (50).

For optional height positioning, the fastening element (30) in the screw axis an increase (32), that the arms (31) of the fastener in height coincides with the lateral groove (11) in the board (10).

The outer contour (32) of the arm (31) of the fastening element (30) can be angled, so that in the groove (12) after turning a larger bearing surface (32) is formed and the spin is prevented by insufficient support.

Furthermore, a better connection between the fastening element (30) and board (10) can be achieved by a tip, not shown, a kind of nail or mandrel on the clamping surface. Due to the small cross-sectional area of the mandrel, it is driven into the board (10) during the rotation of the fastening element (30) and fixed there. As a result, an independent release of the fastening element (30) by thermal expansions and fluctuations by the water absorption of the boards (10) is prevented or at least made more difficult.

The fastening element (30) may consist of plastic, fiber-reinforced plastic, in particular glass fiber or wood fiber reinforced plastic or metal, or light metal, in particular an aluminum alloy. Both the shim (20), as well as the fastener (30) are molded parts, which are preferably produced by injection molding in plastic or fiber-reinforced plastic, or are manufactured in aluminum die-casting.

The boards (10) may be formed of wood, wood-plastic composite, but also unreinforced or reinforced, or filled plastic, or aluminum as a solid or hollow chamber profile.

The boards (10) are typically planed timber in the material wood.

If plastics, or wood fiber reinforced plastics used is the preferred manufacturing process for both hollow chamber, as well as solid profiles extrusion.

In the case of metal profiles as a board (10) these are preferably extruded.

The inventive design of the installation of an entire surface via suitable shims (20) is a simple replacement possibility of individual boards (10) given before the final attachment.

Once the installation surface can be described as finished and no adaptation work is more necessary, the attachment of all boards (10) can take place. This can be visible on the one hand, but also with the described invisible connection with the fastening element (30) according to the invention.

It is also possible to use the base element (20), as well as the fastening element (30) for a step-by-step board (10) for board, which, although not applying some advantages, still provides a substantial improvement over the prior art offers mounting options, so that here too the lower element (20), as well as the fastener (30) are to be regarded as new.

Since all boards (10) are attached later, it is also easily possible to solve individual fasteners and replace in case of repair.
