- CLAMPING DRIVE SYSTEM -

The application area of the innovation are sports fields that are covered with artificial turf.

Artificial turf is mainly laid loosely on asphalt and must be used in the edge areas partially enclosed or fastened under tension.

So far there have been the following laying practices:

a / The artificial turf was clamped and screwed in a circumferential channel using grating. Disadvantage;

High costs due to the surrounding channel. Due to the screw connection, it is prone to corrosion and very wage-intensive.

b / The artificial turf was pulled over a normal concrete curb and on the outside in a concrete chair nailed or screwed.

Disadvantage:

The point-by-point fastening can cause dents in the edge area of the artificial turf.

Due to the adjacent surface required on the outside it is no longer possible to re-tension the lawn; In addition, the lawn in this area can e.g. be damaged or burned when paving the asphalt.

The task of the innovation consists in the execution of a component, which on the one hand is the artificial turf absolutely holds in place in a non-corrosive manner and allows re-tensioning at any time, and on the other hand that which has to be removed from the surface Drains off water without any problems.

The artificial turf (1) is held in place and tensioned in a wedge-shaped slot (2) in various Component variants can be produced and undercut on one side.

The artificial turf (1) is inserted into the slot and held in place with special wedges (3). In the undercut In room (2a), the artificial turf is pressed through the special wedge and thus held firmly in place. The side of the wedge facing away from the artificial turf has teeth (6) which are set upwards and which fit firmly into the opposite one Side press.

The wedge is driven in with a hand hammer. For any repair work, the same is done using a
The hook is levered out and the lawn can be re-tensioned. This reduces the otherwise usual installation costs by approx. 40%.

So the most important features of the innovation are the
Slot (2) in the various component variants
and the special wedge (3), which will be discussed in detail later.

The surface water is drained through the slit into channel channels (4) running underneath or through drainage pipes (5) into the underground drainage. The wedges hammered in at a distance act like one
Grate for the water passage.

The construction of the various components enables problem-free installation with all conventional ones
Devices and machines. The adjacent base layers of the substructure can be right up to the components
mechanically introduced and compacted without the risk of breakage.

The slot (2) in the various component variants is designed as a continuous opening with a surface (2a) that is undershot on one side and tapers downwards somewhat in a wedge shape. It either ends in one
underlying gutter channel (4) or in the so-called drainage pipe (5).

The most important feature, the wedge (3), is stepped as shown in drawing III and has sharp-edged longitudinal ribs (6) on both sides.

The step (3a) formed on one side presses part of the elastic artificial turf when it is wedged into the undercut area (2a) so that the artificial turf is held absolutely securely. Should so-called bumps arise in the artificial turf in the edge area of the playing fields, which are caused by different Temperatures can occur, the wedges can be loosened with a special tool and the artificial turf can be tightened. Drawings I / II and III represent the following Application examples are:

Drawing I shows a "drainage tensioning element" as a so-called Slotted stone, which is made from a plastic concrete, for example. Figure 1 shows a cross section through the component in the area of the water drainage pipe (5). Figure 2 shows a longitudinal section approximately in the middle of the slit stone. FIG. 3 shows a variant with a rubber profile cast on one side (8th).

The construction of the slotted stone is such that it can be moved like a normal curb stone. the lateral recesses (9) and the widened foot (10)

serve at the same time to save weight and material and for good anchoring in the concrete. In Figure 1 is the The upper edge next to the lawn is slightly deeper, so that e.g. the adjacent synthetic surface (12) (e.g. raceways) can be brought up to the slot.

As shown in FIG. 3, an absolutely soft, low-injury upper edge is thus created. Drawing II shows a "drainage tensioning element" as a so-called slot channel. There is only one special for this Slot cover required, which is laid on a known conventional gutter. This component will primarily installed where there is a deeper running track next to the turf playing field that has to be drained on the surface, "Figure 4 shows one Cross-section through the component with the arrangement of the wedge (3K) Here, too, a rubber profile (8) is installed on the track side Arrows shown. It runs over inlet slots (11) to the gutter channel (4). Figure 5 shows the top view of the component, with the continuous slot (2) and the variable arrangement of the wedges (3). Drawing III shows the main feature of the Innovation, namely the wedge, which can be made from a plastic material, for example.

Figure 7 shows a perspective view where the double-sided toothing (6) and the one-sided trained level (3a) are visible. FIG. 8 shows a cross section with an indication of the artificial turf (1). Here you can clearly see how the elastic artificial turf (1) is formed through the one-sided Step (3a) of the wedge (3) presses into the undercut surface (2a) and is thus held absolutely securely will.

Claims (1)

- patent claims - \ 1 / J "tension drainage system" for fastening and bracing of artificial turf, characterized in that in variable components a continuous Slot (2) is arranged in a wedge shape, which has an undercut surface (2a) on one side. 2 / "tension drainage system" according to claim 1, characterized in that the continuous slot (2) opens into a gutter channel (4) or drainage pipe (5). 3 / "tension drainage system" according to claim 1 + 2, characterized characterized in that the artificial turf (1) introduced into the slot (2) is braced with special wedges (3) will. 4 / "Tension drainage system" according to claims 1-3, characterized in that the special wedges (3) are toothed on both sides (6) and a step (3a) widened on one side, into which the elastic artificial turf (1) is pressed »The special Position of the toothing (6) causes the wedges to automatically claw under tension. 5 / "tension drainage system" according to claims 1-4, characterized in that the variable components so are constructed that the surface by on-site plastic application (12) or by a firmly cast rubber profile (8) is absolutely soft.
