The technical field

The invention relates to synthetic grass derno with filler inside it in order to provide an artificial surface for sporting purposes and for growing vegetables and other plants; in particular to synthetic grass derno with built-in temperature control system to control the temperature conditions of the artificial surface.

Background of the invention

The problem of creating high-quality all-weather grass surfaces for sports games and content for recreational purposes and these active sports like football, there is a long time.

Recent technical solution to this problem provided the use of artificial surfaces instead of natural grass surfaces that do not have the wear resistance and require care in large amounts. While the grass on the surface with natural grass grows poorly, especially in fully covered stadiums. Surface with synthetic grass compared to surfaces with natural grass is much more durable, does not require significant care and it can be used in indoor stadiums. Enhanced surface with synthetic grass described in the patent application Canada No. 2218314 of the applicant, filed October 16, 1997, Surface synthetic grass described in specified for the VCE, contains widely spaced from each other a synthetic tape from fiberglass. The length of the tape is approximately two times the length of the interval between the rows of ribbons. On the basis of synthetic grass is laid loose material; and the thickness of the granular material is at least two-thirds of the length of the tape. Strips of tape are attached to the strips of bonding material applied to the underside of the base or Mat. Strip binding material are arranged with an interval between them, and they leave a certain area bases uncovered, thereby providing improved drainage.

The bulk material of the filler is also described in U.S. patent No. 5958527 of the applicant, issued September 28, 1999

In cold climatic conditions outdoor stadiums turf synthetic grass can be heated for melting snow or ice on the turf in order to ensure appropriate conditions required for surface conducting sports and games. But if the turf synthetic grass is used in very warm climates, it is desirable to cool the grassy turf.

For melting and drying of surfaces with natural, synthetic grass designed heating system, such as electrical, fluid and air heat. Electric heating is provided by elements electricaccelerator, fluid heated by passing a heating fluid through the network of heating pipes; and the air heated by passing heated air through the distribution piping network. Typically, these elements of the electric resistance of the pipe fluid heating and distribution pipeline network established within the framework of the playing field under the turf with natural or synthetic grass. Examples of electric heating fluid heating and air heating are described respectively in U.S. patent No. 5046308, No. 5120158 and No. 4462184.

In warm climates the surface of the turf synthetic grass to be cooled, which is usually done by filing moisture to synthetic surfaces with circulating cold water under a synthetic surface. This solution is also described in U.S. patent No. 4462184.

It is also desirable to provide a thermal management system for an artificial surface with organic cultivating environment for growing plants, to comply with specific temperature requirements for plant roots.

A disadvantage of the known heating systems is that much of the heat energy is lost, and only a small portion of thermal energy comes to the surface to melt snow or ice on the surface, since the elements electr the ical resistance and piping systems located inside the playing field under natural turf grass or under a synthetic surfaces, usually in a bearing layer of the field. Therefore, most of thermal energy by heating the surface of the playing field is spent on heating the base layer.

It is therefore necessary to provide an artificial surface with a heating and cooling system with increased thermal efficiency.

The invention

One of the objectives of the present invention is to provide an artificial surface with built-in temperature control system for sporting and other purposes.

Another objective of the present invention is to provide an artificial surface for sports and other purposes, containing a heating system with improved thermal efficiency.

Another objective of the present invention is to provide an artificial surface for sports and other purposes, containing a cooling system with improved thermal efficiency.

The present invention in General is directed to the provision of artificial surfaces with built-in temperature control system for sporting and other purposes. Artificial surface contains a synthetic turf containing elastic supporting plate made with the possibility of its installation on the media. Filling a layer of granular material placed on the surface of the elastic carrier sheet. Bulk m is a material predetermined choose at least one from the group consisting of solid granules of elastic granules and cultivating environment. Artificial surface also contains many parallel rows of synthetic ribbons, representing a plate of grass and protruding upward from the elastic carrier sheet and through the layer of filler. Thermostatic means attached to an elastic bearing sheet to carry out a controlled temperature conditions basics of synthetic turf, synthetic tape and a layer of filler.

According to one aspect of the present invention, the vehicle control contains a flexible electric heating element, configured to attach to a power source, for converting the electric current into heat energy. Flexible electric heating element according to one implementation of the present invention is planar and can be laminated to an elastic carrier sheet. According to another implementation of the present invention, a flexible electric heating element has a power cord attached to the upper surface of the elastic carrier sheet. Electrical wire is installed inside the water layer. Electric heating element preferably includes in its membership many of elongated sections parallel to the poisons of synthetic ribbons. The corresponding extended sections are located in the intervals between the rows of synthetic ribbons and made in the form of a layer on a flexible support sheet. Or the relevant extended sections can be associated with the top surface of the elastic carrier sheet using a hot-melt adhesive activation temperature above a predetermined temperature, at which the electric heating element converts the electric current into heat. This method can be applied for the conversion of existing sports fields with these characteristics in a heated area.

Filling layer preferably contains distributes heat of bulk material with a relative effective specific conductivity. Distributes heat the granular material is located at the bottom of the water layer and in contact with thermostatic means for regulating the temperature conditions synthetic bases, synthetic tapes and filling layer, and simultaneously provides elasticity to the surface.

According to another implementation of the present invention a filling layer contains soil for growing plants on artificial surfaces. Synthetic tape protect the soil on the artificial surface from wind erosion.

In accordance with another aspect of the present image is the shadow thermostatic means include a flexible tube instead of the electric heating element; while this tube may be connected to a source of water to circulate water. If it circulates hot water, the flexible tube can be used as the heating device for an artificial surface. If it circulates cold water, the flexible tube can be used as a cooling device for an artificial surface. If it is used as the cooling device, the flexible tube is preferably perforated as tube drip irrigation, and through the fluid communication with the filling layer through its perforations. Thus, moisture can be fed into a filling layer, and it will perform a cooling function during its evaporation. Moisture is also desirable, especially when the filling layer has such cultivating layer, as soil for growing plants. When using the option with the cultivation of plants secondary basis herbs can be made impervious to save water. The amount of water running in the system, can be controlled, to reduce evaporation in the case of the use of sprinkler systems.

Similarly, the electrical heating element is a flexible tube is relatively thin, has many parallel sections located between the rows of synthetic ribbons, and attached the to the upper surface of the elastic carrier sheet or embedded in an elastic supporting plate.

Electric heating element or flexible water tube embedded in an artificial surface, and therefore, when heating or cooling base layer under artificial surface will be losing a relatively small amount of energy. Thus it is possible to provide higher performance and lower operating costs. Electric heating elements or flexible water tube can be conveniently attached to artificial surfaces either on the spot or at the time of manufacture, and thus eliminates the need to create expensive underground system.

Other advantages and features of the invention are explained in the following description of the preferred implementations.

Detailed description of preferred embodiments of the invention

Referring to figures 1 and 2: surface synthetic grass with the General designation 10 according to the invention has a thin elastic supporting plate 12 with parallel rows of 13 synthetic strips or tapes 15, protruding upwards from the elastic carrier sheet 12. A relatively thick layer 17 of the filling material of the particles is located above the elastic carrier sheet 12, which is attached tape 15 in a relatively vertical position on the support sheet 12. Supporting plate 12 is mounted on a carrier substrate (not shown).

Elastic supporting plate 12, as shown in figure 3 and 6, contains two layers 19, 21. The top layer 21 and the bottom layer 19 can be made of woven or malperformance polypropylene material. Plastic strip 15 is threaded through the supporting plate 12, passing through on the as layer 19 and 21.

Although supporting plate 12 is shown consisting of two layers, it can also perform as a single layer or multiple. One or more layers of elastic carrier sheet 12 to improve drainage can be made of malperformance woven material. At least the top layer 21 of the carrier sheet 12 may be malperformance with fluffy synthetic fibers (not shown)functioning as a wick to provide a means of removing moisture through the layer. These fluffy fibers improve the drainage of the surface.

Tape 15 is made from an appropriate synthetic material, extruded in a relatively wide and thin strip. The preferred plastic material is polyethylene is soft and has good resistance to abrasion. But for the manufacture of the tape 15 can also be used polypropylene.

Details regarding the implementation of the carrier sheet 12 and the tape 15 is described in published patent application Canada No. 2218314 of the applicant, which is incorporated herein by reference and are not further explained.

The spacing between the rows 13 of the tape 15 is dependent on the action on the surface. For example, the spikes on the shoes of athletes of different sports have an average interval of about three quarters of an inch. The spikes on their shoes for football can have a wider interval than siposova for baseball. In sports such as horse racing, it is believed that between rows should be wider interval commensurate with the hoof of the horse. That is, it is assumed that the races may be required spacing between rows to 2 and a quarter inches, with proportionally longer ribbon to five inches for other uses.

It should be noted that the rows of 13 tapes 15 are between the interval from five-eighths of an inch to two and a quarter inches, and this interval is appropriate to accommodate it thin flexible water tube. Therefore, in the surface 10 according to the present invention it is possible to embed thermal control system.

In accordance with another implementation of the present invention, shown in figures 1 and 3, the insulated electric heating wires 23 are parallel to the rows of 13 synthetic tapes 15 and located in the intervals between the rows 13 of synthetic tapes 15. Electric heating wire 23 can be connected according to Figure 4 or be connected in parallel according to Figure 5.

Electric heating wire 23 can be associated with the top of the carrier sheet 12 by means of hot-melt adhesive 25 - according to Figure 4. The activation temperature of the hot-melt adhesive 25 is higher than the nominal operating temperature of the heating elements, and therefore the electrical connection of the heating wires is 23 with a flexible bearing sheet 12 no impacts are experiencing and never broken due to overheating. Connection electrical heating wires 23 with a flexible bearing sheet 12 can be performed either on-site or during production. In the case of execution on the spot areas of hot-melt adhesive 25 is distributed, as shown in figure 4, between the carrier sheet 12 and the electric heater wire 23. Electric heating wire 23 is connected with a power source (not shown), voltage is above the normal operating voltage; and electric heating wires 23 are heated, such as a rheostat, to the activating temperature of the hot-melt adhesive 25 to melt sections of the hot-melt adhesive 25. Electric heating wires 23 are associated with elastic carrier sheet 12 after disconnecting the power supply, cooling and curing sections hot-melt adhesive 25.

You can also use the plastic clamps (not shown) for attaching electrical heating wires 23 to the supporting sheet 12. These clamps can punch supporting plate 12 to secure them around the electric heating wires 23 and to the supporting sheet 12. These steps are preferably performed at the time of manufacture.

According to another implementation of the present invention and according to Figure 3 electrical channels 27 are embedded in the support sheet 12 artificial surface 10. E-the historical channels 27 can be made of thin heating wire types which is used for heating the eaves of the roof to melt snow to avoid falling snow, dangerous for passers-by. These wires can also be channels of low voltage and can be modified according to local requirements artificial surface 10. Electrical channels 27 may be located between two layers 19, 21 of the carrier sheet 12 or laminated to the top of the carrier sheet 12 with additional lamination during the manufacture of the carrier sheet 12. Synthetic tape 15 is then inserted into the supporting plate 12 between the sections of the power channels 27.

Referring to Figure 2: filling the layer of granular material is located on the upper surface of the elastic carrier sheet 12, and the specified granular material contains at least one material from the following group: solid granules, elastic granules and cultivating the environment. According to one implementation of the present invention artificial surface 10 that is used primarily for sporting purposes, contains a filling layer 17 made of a base substrate 29, the middle sublayer 31 and the upper substrate 33. The base sublayer 29 essentially consists of solid granules located directly on the upper surface of the carrier sheet 12. Solid pellets of the base substrate 29 are sand is a very effective and inexpensive order the holder efficient heat dissipation. Solid pellets of the base substrate 29 are preferably sand as the first layer of the base substrate 29; and may provide a second layer of more and better material of heat dissipation, such as ceramic granules on top of the sand or in a mixture with sand. These granules should be of a size essentially equal to the size of the granules of sand to granules with additional and improved dissipation of heat does not penetrate down into the sand, if this mixture is undesirable. These pellets are additional and improved heat dissipation may contribute to a more uniform heat dissipation on the horizontal plane of the artificial surface 10. These heat-dissipating granules can also be used for cooling the surface, because they have the absorptive capacity to absorb water, the weight of which is several times higher than their own, at the same time dissipating moisture. The middle sublayer 31 a filling layer 17 is a mixture of solid granules of sand and elastic rubber granules. The mixture can be chosen according to the weight ratio of over 2:1 hard and resilient granules, respectively. The upper sublayer 33 a filling layer 17 is essentially composed of a resilient rubber granules. The filler may be also made of rubber granules, or only the PE the ka.

The upper portion of the synthetic ribbons 15 passes upward from the upper surface of the upper substrate 33 and preferably is bent over the upper surface of the upper layer 33 of the filling layer 17. This can be accomplished, for example, by sweeping the surface with a wire brush or other brush, after installation of the upper layer 33 of the filling layer 17. The ends of the synthetic ribbons 15 split, broken or fibrillated and twisted with each other with formation of a loose network to more it seems to mimic the look of natural grass and thus improve their ability to hold and bind the top layer 33 of the filling layer 17. Thus obtained Dernovoy surface can be performed for multiple uses indoors and outdoors: sports courts, trails for horses and the surface to rest. The filling layer 17 is described in detail in U.S. patent 5958527 of the applicant, which is incorporated herein by reference. But given surface can also be installed and without the need of fibrillatory on the location of the ends of the fibers.

Described above, the filling layer 17 is just one example that can be used in implementing the present invention; and it can contain many combinations of bulk materials, such as substance p is Zinovich, essentially sand, sand, sand bottom and essentially rubber top, rubber-ceramic mixture, and any other similar mixtures. Other additives filling layer 17, which help the filler 17 to dissipate the heat, you can choose from a group of materials other than sand and ceramic granules, including, for example, glass beads, stone particles, granules of lava, steel pellets, granules, coal slag, and any other scattering or transmitting heat pellets. Scattering or transmitting heat pellets can increase the heat transfer in artificial surface 10 away from the electric heating wires or channels 23, 27, through which it is possible to reduce the total length of the heating wire 23 or electrical conduit 27, necessary for the artificial surface 10. It gives a reduction of the total cost of the system during its installation and operation. Moreover, synthetic tape 15 or at least some of the tape 15 can be made of heat reflecting material to even more improve the heat transfer to the filling layer 17 artificial surface 10. Supporting plate 12, at least the top layer 21 can be made of a heat reflecting fibers to cover the supporting sheet 12 directed heat is mainly up to melt ice and snow.

Neobhodimosti, that filling layer 17 may also include cultivating an environment, such as soil, if artificial surface 10 is used for growing vegetables or other plants. The roots should be kept at a temperature warmer than the ambient air temperature in cold climates. In this case, the filling layer 17 may, optionally, contain only organic cultivating environment: cultivating organic environment or some inert material, increasing or retaining heat; or organic cultivating environment and ceramic fraction, which effectively retains moisture. Variations of the composition of the filling layer 17 can be selected taking into account emerging challenges in different climatic conditions such as drought or cold. Bound upper portion of the synthetic ribbons 15, according to Figure 2, can effectively keep cultivating the environment from the effects of wind erosion to the artificial surface 10 with which the environment could be used in windy areas.

To modify playgrounds or landscaped surface through having a filler artificial surface of this type without pre-installed heating system it is only necessary to remove the filling layer blow off with compressed air, then install necessary is Elektricheskie heating wires, melt glue to attach in place of the wire. Filling layer is then arrange again and perform the electrical connections along the perimeter of the artificial surface. The necessary electrical connections can be installed in boxes in the ground along the perimeter of the artificial surface. For repair of the heating system after installation there is no need to provide access to any site beneath the surface area. Artificial surface, especially when it is used for sporting purposes, made with the possibility of heat, so as not to interrupt the sports activities even in bad weather conditions. You can install a permanent power supply for the heating system, but it can provide cost savings through the use of a portable generator in the right cases, if the space is not used often.

You can take measures to reduce energy consumption. If heavy snowfall closes artificial surface 10, then most of the snow cover can first remove the snow plows or other means, and then the heating system will need to remove the only remaining snow. To save the filling layer 17 in its design condition generated enough heat, and the filling layer 17 is not formed lumps and he is not replaced is longer. After artificial surface 10 will reach this state, the heating system can be turned off to save energy costs.

Time to start heating wires or electrical channels 23, 27 takes only minutes. The time needed for the proper heating of the surface, can be minutes or hours, which is much smaller than conventional systems that use heating the fluid circulating through the pipes under the artificial surface 10 and the base.

According to another implementation of the invention in accordance with 6 artificial surface 30 contains many thin flexible tube 29, which replace section 23 electric heating elements 23 or electrical channels 27, shown in figures 1 and 3. Other components and characteristics similar to the implementations described with reference to Figures 1 to 5, and therefore no longer explained. Components similar to the components according to Figure 1-5, are indicated by the same reference designations as in Fig.6. Flexible thin tube 29 may be sections made integral with a single tube, similar to the solution shown in Figure 4, or they can through the fluid to communicate with the parallel connection of the tubes according to Figure 5. Tube 29 is connected to the pump and a water source (not shown), and water under pressure is circulated through the tubes 29. If trubk the m circulates hot water, when this is heated filling layer 17. If the water temperature is lower than the temperature of the artificial surface 30 in warm weather, the filling layer 17 can be cooled by cold water circulating through the tubes 29.

Tube 29 can be attached to an elastic bearing sheet 12 or adhesive, or clips. Tube 29 can also be laminated in the supporting plate 12.

For more efficient cooling tube 29 is preferably perforated, and therefore the tube 29 through the fluid communicated with the filling layer 17 through the perforations 32. Water under pressure is circulated through the tubes 29, and part of the water enters the filling layer 17 through the perforations 32 of the tubes 29. Perforations 32 are uniformly distributed along the tube 29, and the flow of water is regulated so that coming into the filling layer 17 water does not flood filling layer 17 and synthetic tape 15. The capillary action of the sand layer allows moisture to move up in the filler, and therefore it acts as a coolant in the filler. Heat is removed from the layer 17 of the filler and synthetic tapes 15 and also from the supporting sheet 12, if contained in an artificial surface 30, the moisture evaporates, causing the temperature of the artificial surface is reduced.

The temperature of the water circulating through the tubes according to the that option, does not have to be below the ambient temperature, as the cooling is achieved by evaporation, not heat transfer.

In this type of application depicted in Figure 5, the solution preferably of tubing 29. The tubes 29 are connected in parallel, resulting in reduced water pressure drop along the length of the tube, as opposed to pipe 29, connected in series according to Figure 4. The moisture is distributed more evenly over the entire area of artificial surfaces 30. Implementation according to 6 can be used as sports grounds or for recreation, or as a surface for growing plants; when this type of use will determine the choice of bulk materials selected for the filling layer 17.

It should be noted that the artificial surface 30 with cultivating an environment in filling layer 17 according to Fig.6 is particularly effective for growing vegetables and plants. Moisture is supplied through tubes 29 may be used not only as a refrigerant, but also can provide the necessary water for vegetables or plants grown in the filling layer 17. Appropriate water should be carefully adjusted to prevent flooding artificial surface 30, while ensuring the cooling of the artificial surface 30. W the hex bearing floor, imposed on the supporting plate 12, can be made impervious to the place in which the amount of water permitted to flow through the perforated tubes, enough for maximising growing conditions for this plant.

SUBSTANCE: invention relates to grain materials with multilayer polymer coating and a method of producing said material. The method involves mixing a first thermoplastic polymer with a grainy substrate to form a mixture at temperature higher than the melting point of the first thermoplastic polymer, cooling the mixture to temperature lower than the melting point of the first thermoplastic polymer and merging the cooled mixture with a second thermoplastic polymer, where the melting point of the second thermoplastic polymer is lower than the temperature of the cooled mixture. Further, the merged mixture is cooled to temperature lower than the melting point of the second polymer. Use of polymers with low melting point in the grain material can successfully lower requirements for heating and cooling, thus reducing power consumption of the process, leading to shorter duration of the cycle. The obtained grain material is used as filler for artificial coatings.

EFFECT: grainy filler has uniform and homogeneous coating, which makes the surface of the filler soft, thereby giving excellent wear resistance, good aesthetic and tactual properties, and ensures safety for the player.

SUBSTANCE: according to the invention, a carrier is at least partially equipped with one additional material-component, which may expand and permanently hold the increased volume on the specified part of the carrier under influence of external stimulating actions after insertion into an artificial mat. Using the additional material-component, which may expand and permanently hold the increased volume, at least on a part of the carrier, makes it possible to create an artificial lawn with an additional damping property, which applies a positive effect at playing characteristics of the sports field, for instance, absorption of pushes, recovery of energy and deformation in vertical direction, and thanks to which, moreover, it becomes possible to reduce the number of injuries suffered by players.

EFFECT: development of a new type of an artificial lawn, using which eliminates the necessity in a filler material, without which the coating would have harmful effect at playing characteristics of a sports field.
