Description

Patent Descriptive Report for "SYNTHETIC GRASS LINE".

The present invention relates to a synthetic grass line, which is formed on a ground, for example in a grass sports court, to a synthetic grass line forming soil treatment apparatus as well as to a process for forming a synthetic gram line.

In sports square soils, especially grass sports squares, it is necessary to mark the required field by line for the type of sport in question. A known process for forming these lines is the use of lime or chalk dust or the like, which is sprayed onto the soil or grass through a dusting machine. It is also known to form the lines with spray paint. Due to weather influences such as wind and rain, however, these lines do not last long, so often, often weekly, must be renewed. In addition, there may be accumulations of dust which lead to hardening of the grass, so that at the point in question results in a hole in the grass area.

In addition, it is known to introduce tinted synthetic grasses into the soil to form a line. The lines thus formed are generally very thin, so that several lines must be formed side by side to produce, for example, the line width of about 12 cm required on a football field. The problem then arises that between the different parts of synthetic grass lines weeds or grasses may grow, which cover the parts of synthetic grass line, so that the synthetic grass line can no longer or poorly be grown. Viewed. In addition, it is only possible to shorten the plants by shortening the growing between the different parts of the line to restore the visibility of the line. The introduction of several side-by-side line parts is still very laborious.

Therefore, it is an object of the present invention, while avoiding the aforementioned disadvantages, to provide a synthetic grass which is suitable for forming a synthetic grass line on a soil, the synthetic grass line having to be formed simply. In addition, a soil tillage machine and a process for forming such a synthetic grass line should be provided.

This objective is achieved through the characteristics of the claims

1, 10 and 16.

Advantageously, the invention provides that a continuous piece of synthetic grass for forming a synthetic grass line on a ground, preferably a grass sports court, consists of a continuous piece of textile support stretched lengthwise and Various synthetic grass fibers. The long stretched continuous textile carrier has a fiber segment extending longitudinally of the continuous textile carrier and two lateral segments, the lateral segments being arranged laterally to the fiber segment and parallel to the fiber segment and being seated respectively for a fold extending longitudinally of the continuous piece of textile support. In the fiber segment, several synthetic grass fibers are arranged and form several parallel rows of synthetic grass fibers, each row of synthetic grass fibers extending longitudinally of the continuous support piece and the grass fibers being stressed. surface of the fiber segment of the continuous support piece. In the folded state of the continuous piece of synthetic grass, the folds, which are formed with the side segments, are respectively insertable into a groove in the ground for fixing the synthetic grass line that the fiber segment at least partially covers. soil region.

With the continuous piece of synthetic grass according to the invention a synthetic grass line can be provided which can be fixed to the ground in a simple manner, enabling stable and lasting attachment by inserting the folds into a groove in the ground. . Thanks to the fiber segment, which covers at least partially

In particular, the region of soil arranged between the furrows ensures that no grass and / or weeds can emerge or grow between the rows of synthetic grass fibers by which synthetic grass fibers can be covered.

Thus, the synthetic grass line formed by the continuous piece of synthetic grass according to the invention has an extremely long life and it is not necessary to costly remove or cut grass or weeds lying between the fiber rows. of synthetic grass.

Preferably, it is envisaged that several synthetic grass fibers will be bundled into fiber bundles and the various rows of parallel synthetic fibers will be formed from rows of fiber bundles. By providing fiber bundles of various synthetic grass fibers, over the fiber segment a large number of densely contiguous synthetic grass fibers can be arranged advantageously so that the fiber segment with the same fibers can be arranged. Synthetic grass fibers have a particularly authentic appearance. This produces a line of synthetic grass that stands out from natural grasses by its color but has a similar shape to natural grasses.

In a preferred embodiment it is provided that in the fiber segment of the continuous textile support piece several rows of parallel holes consisting of several holes are arranged, one or more synthetic grass fibers being threaded into the different holes and attached to the contiguous piece. - bare textile support. This makes it possible to produce the continuous piece of synthetic grass in a particularly simple way, while simultaneously synthetic grass fibers can be arranged and fixed to the continuous piece of textile support in an advantageous manner.

It may then be provided that respectively two synthetic grass fibers of two neighboring fiber bundles are formed from a filament which is guided from the side of the continuous support piece opposite the surface of the fiber segment with respectively one end by respectively. a hole of two neighboring holes. In other words, the filament for forming two synthetic grass fibers is fitted by the rear side of the continuous support piece by two neighboring holes. In this way, synthetic grass fibers in the fiber segment of continuous textile support pieces can be produced simply and very quickly, as, for example, several filaments are simultaneously joined by the holes, so that two Fiber bundles can be produced with one production step.

It may then be provided that the synthetic grass fibers on the side of the continuous support piece opposite the surface of the fiber segment are sewn, glued and / or welded. This ensures a stable fixation of synthetic grass fibers to the continuous support piece in a simple manner.

It may be provided that the continuous support piece consists of several layers, preferably a lattice fabric, a fleece and a nylon fabric. In total it may be envisaged that the constitution will be such that natural grass roots can penetrate at least partially into the continuous support piece, so that a continuous attachment of the continuous synthetic grass piece to the ground is possible.

Preferably, it is provided that the synthetic grass fibers consist of polyethylene, polyamide and / or polypropylene.

Synthetic grass fibers and / or synthetic grass fiber elements may consist of polyethylene, polyamide and / or polypropylene. These materials have proven to be especially suitable for use in a continuous piece of synthetic grass.

In an especially preferred embodiment, the synthetic grass fibers have a twisted cross section per se. Thus, despite a small cross section, the synthetic grass fibers are given special strength so that they project advantageously from the fiber segment of the continuous support piece. In addition, the twist produces greater elasticity of the synthetic grass fibers, so that the fibers advantageously return to the protruding position of the continuous textile support piece after a deformation. Thus, either each synthetic grass fiber may be individually twisted or two or more synthetic grass fibers may be twisted or twisted together. It is also possible for a synthetic grass fiber to consist of several individual fibers that are twisted.

It may be expected that the synthetic grass fiber elements, the synthetic grass fibers and / or the continuous support member will be a UV stable material.

The invention further relates to a soil treatment apparatus for forming a synthetic grass line in a continuous piece of synthetic grass soil according to the invention, wherein a furrow device is provided. for forming two parallel grooves and a line insertion device disposed after the groove forming device in the running direction of the soil treatment apparatus. The line insertion device has two spaced apart compression edges, the distance of the compression edges being adapted to the width of the fiber segment of the continuous piece of synthetic grass and the line insertion device. The line is so designed that the side segments of the continuous piece of synthetic grass for forming the folds are settable around the compression edges and insertable by the line inserter into the grooves in the ground.

The soil treatment apparatus according to the invention advantageously enables a synthetic grass line according to the invention to be applied with a ground apparatus and fixed to the ground. Such a soil treatment apparatus can, for example, be pulled by a conventional agricultural traction machine. The provision of the furrow forming device enables the formation of straight furrows in the ground into which the line insert can compress the folds of the continuous piece of synthetic grass. This enables very fast application and attachment of the synthetic grass line to the ground without the need for additional work steps. As the continuous piece of synthetic grass according to the invention can be stored for example rolled up, with the soil treatment apparatus according to the invention a long line of synthetic grass can be formed in the ground without another continuous piece of soil. Synthetic grass needs to be added to the soil treatment device.

In such a soil treatment apparatus it may further be provided that the furrow forming device may be moved to a position where the furrow forming device engages only partially or not at all in the ground, so that the furrow forming device can line insertion inserts the continuous piece of synthetic grass into existing grooves. This may be the case when an already laid line is to be renewed and after extraction of the continuous piece of old synthetic grass there are grooves in the soil.

According to the invention it may be provided that the device formed

groove pain consists of several rotating blades, the blades preferably arranged coaxially with each other. The provision of rotary blades as a furrow forming device has the advantage that the narrow furrows advantageous for the use of continuous pieces of synthetic grass according to the invention can be formed simply by a notch in the ground.

It may be provided that an adductor device is arranged to add a continuous piece of synthetic grass to the line insertion device in the soil care apparatus, preferably the adductor device tapers towards the line inserter. In this way it is possible to add the continuous pieces of synthetic grass to the line insertion devices and to insert the continuous piece of synthetic grass into the soil in an advantageous way.

The adduction device enables an orderly adduction of the continuous piece of synthetic grass to the line insertion device, so that the soil care apparatus can introduce the continuous piece of synthetic grass straight into the ground. It is therefore advantageous for the raceway to taper towards the aligning insert because the continuous piece of synthetic grass in the initial state is essentially wider than the synthetic grass line formed on the ground by inserting the continuous piece of grass. synthetic ma.

The adductor device may consist of two guide supports disposed at an angle to each other, which are aligned with the line inserter, preferably to the compression edges of the line inserter. The constitution of the two guide support adductor device makes it possible to add the continuous piece of synthetic grass advantageously.

It may then be provided that a first intermediate space formed between the guide supports protrudes into a second intermediate space between the compression edges of the line insertion device, the first and second intermediate spaces being adjusted to the housing a fiber segment of the continuous piece of support of the continuous piece of synthetic grass.

Thus, it is advantageously possible that the folds of the continuous piece of synthetic grass, which are inserted into the grooves in the ground, are formed as the side segments of the continuous piece of synthetic grass are folded around the guide supports and compression edges of the line inserter. By housing the fiber segment of the continuous piece of support of the continuous piece of synthetic grass in the first and second intermediate spaces the fiber segment is enveloped and, upon insertion of the folds provided for in the invention, of the continuous piece of fiber. Synthetic grass in the grooves always have enough material from the continuous support piece fiber segment available, so that the continuous support piece in the fiber segment does not tear. The fiber segment is thus seated on the soil segment which lies between furrows in the soil, so that this part of the soil is covered. The line insertion device and / or the adductor device may

In this way, the insertion operation envisaged according to the invention is assisted and a working mode of the non-failing soil treatment machine is guaranteed, as the guide means compress the continuous piece of synthetic grass to the advantageous shape. insert operation.

Preferably it is provided that the soil care apparatus has a cylinder disposed after the line inserter. With the aid of the cylinder, the continuous piece of synthetic grass inserted into the ground can be further fixed as the grooves are compressed into the ground with the aid of the cylinder.

In addition, the invention provides a process for forming a synthetic grass line in a soil, preferably a grass court with the following steps:

a) formation of two parallel grooves in the ground, b) alignment of a continuous piece of synthetic grass over

the grooves, the continuous piece of synthetic grass consisting of a continuous piece of textile backing having a fiber segment having protruding synthetic grass fibers and two side segments,

c) folding the side segments to respectively

fold,

d) compressing the bend into respectively one of the ground grooves for securing the continuous piece of synthetic grass, such that the fiber segment at least partially covers a region of the ground and the synthetic grass fibers protrude from the fiber segment

for formation of synthetic grass line.

The process according to the invention makes it possible to advantageously form a synthetic grass line on a soil. By providing two parallel grooves in which the folds of a continuous piece of synthetic grass are compressed, the continuous piece of synthetic grass can be fixed to the ground in a simple manner for forming the synthetic grass line. Due to the fact that the part of the continuous piece of synthetic grass, of which the synthetic grass fibers stand out, at least partially covers a region of the soil, it is prevented that natural grasses or weeds may grow between the fibers. of synthetic grass and thus detract from the appearance of the synthetic grass line. Natural weeds and grasses do not therefore need to be removed between synthetic grass fibers.

It is preferably provided in the invention that the continuous piece of

synthetic grass is a continuous piece of synthetic grass according to the present invention.

It may also be envisaged that a soil treatment apparatus according to the invention be employed for forming the synthetic grass line.

Preferably it is provided that the process according to the invention has another step:

e) compaction of the soil such that the furrows are compressed into the soil. The invention will be explained in detail below with reference to

Figure 6 is a schematic view of a soil treatment apparatus according to the invention for inserting a continuous piece of synthetic grass according to the invention into the operating soil.

Figure 1 shows a continuous piece of synthetic grass 1 according to the invention for forming a synthetic grass line on a ground 14, preferably a grass sports court, schematically in perspective view. The continuous piece of synthetic grass 1 is represented in the initial state. The continuous piece of synthetic grass 1 consists of a continuous piece of textile support 3 stretched out over which several synthetic grass fibers 9 are arranged as fiber bundle 5. Fiber bundles 5 are arranged in several rows 7 and protrude from the surface 8 of the continuous textile support piece 3.

The continuous textile support piece 3 is subdivided into a fiber segment 6, wherein the synthetic grass fibers 9 are arranged in the form of fiber bundles 5, and two side segments 4. The fiber segment 6 and the side segments 4 are then arranged parallel and extend longitudinally of the continuous textile support piece 3.

For the attachment of the synthetic grass fibers 9 or the fiber bundles 5 to the textile support member 3, several rows of parallel holes 10 extending longitudinally of the continuous textile support member 3, which consist respectively of several holes 10a in each other. that the synthetic grain fibers 9 or the fiber bundles 5 are threaded.

The continuous textile support piece 3 can be produced from virtually any type of textile material as long as this material is resistant to environmental influences. The textile material may be a fabric, a felt or also a fleece.

Synthetic grass fiber elements and synthetic grass fibers may be made of a plastic, for example polyethylene, polyamide or polypropylene. Preferably, the plastic selected for synthetic grass fibers is UV stable.

Figures 2 and 3 show an example of the execution of a continuous piece of synthetic grass 1 according to the invention in the grounded state. By insertion into the ground, for example in a grass court, the continuous piece of synthetic grass 1 forms a line of synthetic grass on the ground 14. In the ground 14 are cut two grooves 15.

Grooves within the scope of the invention may be any recesses drawn lengthwise into a ground, for example also a groove, slot or notch.

The continuous piece of synthetic grass 1 according to the invention is fixed in the grounded state 14 by a clamping effect of the grooves 15 in the ground 14. For this purpose it may be provided that a continuous piece of synthetic grass 1 inserted into the ground 1 is fixed more strongly by further treatment of the soil 14, as, for example, the soil 14 is compacted so that the grooves 15 are compressed. In the representations of the continuous piece of synthetic grass 1 shown in figures 2 and 3 the grooves 15 are shown relatively well open. This representation is for explanation purposes only and does not necessarily reproduce the actual shape of the grooves.

The continuous piece of synthetic grass 1 according to the invention has two folds 17 which are inserted into the grooves 15 at the bottom 14. The folds 17 are formed by folding the side segments 4. The folds 17 of the continuous piece of synthetic grass 1 are then so executed that the fiber segment 6 with the synthetic grass fibers 9 covers the partial region 14a of the soil 14.

Grass plants or weeds lying on the partial region 14a of the soil 14 are thus covered and prevented from growing above the synthetic grass fibers 9.

As best seen in FIG. 3, where the continuous piece of synthetic grass shown in FIG. 2 is shown in another view, it may be provided that the continuous support piece 3 is made of a textile material which may be traversed by roots 18 of the surrounding grass plates, so that the roots 18 of the grass plants additionally attach to the soil the continuous piece of synthetic grass according to the invention.

Figure 4 is schematically depicted in detail an individual synthetic grass fiber. Synthetic grass fiber 9 is itself twisted, that is, it has a twisted cross section. Thanks to such a twisted cross-section, the synthetic grass fiber exhibits better elasticity as well as greater strength, so that the synthetic grass fibers 9 in the grounded state of the continuous synthetic grass piece 1 advantageously protrude from the continuous support piece 3. The high elasticity means that a mechanical load of the fibers, for example due to a ball falling on the synthetic grass line, or a sportsman stepping on the synthetic grass line, does not break the line, ie that is, it deforms plastically, but only undergoes elastic deformation and returns to the initial state after loading.

As shown in Figure 4, synthetic grass fibers 9 may be formed to the extent that a filament 9a is joined by two neighboring holes 10a in the continuous textile support piece 3 on the side of the continuous textile support piece 3 opposite surface 8. so that the two ends of the filament 9a form the synthetic grass fibers 9. On the side 12 of the continuous textile support piece 3 opposite the surface 8, the filament 9a and with it the synthetic grass fibers 9 may be glued together. , welded or stitched. It is also possible that, when producing the continuous piece of synthetic grass 1 according to the invention, several filaments 9a are simultaneously joined by two neighboring holes 10a, so that two fiber bundles 5 of synthetic grass fibers 9 are formed. In this way it is possible to produce the continuous part of

synthetic material according to the invention in a simple and very fast way.

Within the scope of the invention, the synthetic grass fibers 9 may be arranged both individually in the rows 7 and may also be arranged in fiber bundles 5. In FIGS.

When adding the continuous piece of synthetic grass 1, by the guide supports 30 and the compression edges 44 of the thread inserter 42 the folds 17 are formed, as the side segments 4 of the continuous piece of synthetic grass 1 are seated around the edges of the guide supports 30 and the compression edges 44 of the line inserter 42 upon adduction. The fiber segment 6 of the continuous piece of synthetic grass 1 is housed by a first intermediate space 32 between the guide supports 30 and a second intermediate space 46 between the compression edges 44 of the thread inserter 42 and compressed to within or between such intermediate spaces so that the folds 17 of the continuous piece of synthetic grass 1 abut closely around the guide supports 30 and the rests 44 of the line inserter 42.

In the raceway 28 and / or the line inserter 42 there are provided guide means 48 for guiding the continuous synthetic grass piece 1 to ensure a close engagement of the folds of the continuous synthetic grass piece 1 around the compression edges 44 of the line inserter 42. In the embodiment shown in FIGS. 6, the guide means 48 consists of a guide plate disposed in the first intermediate space 32 and the second intermediate space 44, wherein Between the guide plate and the guide supports or the compression edges 44 of the line inserter 42 there are provided slots 43 through which the continuous piece of synthetic grass 1 can be seated.

Looking in the direction of travel, after the furrow forming 24 there may be provided an unrepresented compaction device which is applied to the ground with the continuous piece of synthetic grass inserted, for example to compress the furrows so as to ensuring better attachment of the continuous piece of synthetic grass to the ground.

Other guide means may also be provided which compress the continuous piece of synthetic grass to the correspondingly desired shape. The compression edges of the line inserter have such a selected distance that the fiber segment of the continuous piece of synthetic grass is housed in the formed intermediate space and thus ensures that the folds prior to insertion into the ground abut. narrowly on the compression edges of the line inserter.

Such a soil treatment device has the advantage

that the grooving operation and the synthetic grass line insertion operation are performed in one work step. In addition, the continuous piece of synthetic grass inserted with such a soil treatment apparatus is only under-requested, as the continuous piece of synthetic grass is pressed only into the grooves.
