Description

BACKGROUND

Synthetic surfaces, sometimes referred to as synthetic turf or artificial turf, can replace grass to lower maintenance costs associated with playing fields, lawns, playgrounds, and similar areas. While there are many advantages to synthetic surfaces, one drawback is that, due to the materials of its formulation, a synthetic surface can get much hotter than a natural surface when heated by the sun.

DETAILED DESCRIPTION

The present disclosure relates to heat management for synthetic fields and surfaces. Synthetic surfaces are often installed as playing fields for sports (e.g., football, soccer, baseball, or field hockey) or leisure surfacing (e.g., playgrounds or landscaping). The surface of synthetic fields can appear similar to grass, with various fiber length depending on the application. Frequently spanning a large area, a drawback is that the synthetic surface can get hot in the sun.

The synthetic fibers of the surface may include polymers, such as polyethylene, polypropylene, nylon, a mix of polymer and polyester, which retain heat and reach high temperatures from warm weather and sunlight, which can be a drawback to synthetic surfaces. Notably, sports fields and other surfaces that incorporate synthetic fibers and receive direct sunlight can get up to approximately 40-70 degrees hotter than surrounding air temperatures. For instance, on warmer days, synthetic turf fields can heat to temperatures from 120 to 180° Fahrenheit (48 to 82° Celsius). As a result, playing on synthetic turf having such high temperatures can result in melting shoes, blistered hands or feet, increased risk of dehydration or heatstroke, as well as damage to the artificial turf. Accordingly, the heat retention in synthetic surfaces are problematic.

Manufacturers attempt to solve the heat retention problem in synthetic surfaces using copolymers for synthetic fibers, or including additives in the fiber composition. Alternatively, infill material is added to an installation that is composed of a material that retains less heat. For instance, infill materials having a lighter color or formed of organic materials have been used, such as shredded coconut shells, wood chips, and the like.

Also, installations have included an external watering spray system, configured similar to a traditional sprinkler system that allows watering the field before a game. However, water evaporates quickly and the benefits of the water-cooling effect wears off rapidly. In any event, the standard procedure today for cooling off a synthetic field includes spraying the field with water, which results in an inefficient usage of water and oversaturation of the synthetic surface, making the field difficult or less than ideal to play on. All of these attempts to reduce the temperature of the playing surface have had minimal effect.

Accordingly, various embodiments for a system that can accumulate water from the rain or irrigation are described herein to control a temperature of at least a portion of a synthetic surface (e.g., landscaping or athletic playing field) and maintain a suitable temperature for use thereof. As such, a supply of water or other fluid may be provided to synthetic turf fibers, where such fibers may include those configured to absorb and wick moisture in such a way to provide a passive and/or active cooling effect on the fiber and reduce a temperature of the fiber.

For instance, in various embodiments, a synthetic turf system is described that includes an elastic sub-layer (also referred to as a deflection layer, an impact layer, and/or a shock pad layer) configured to accumulate and retain moisture, and control the evaporation thereof at a predetermined rate. The elastic sub-layer may be positioned below a fiber layer of the synthetic surface. A synthetic surface, such as an artificial field, may be tufted or woven. The system may provide a regulated flow of water below the turf layer to maintain a moisture level in a range of suitable moisture levels in the fibers, thereby constantly cooling the field.

With an evaporating process described herein, less moisture may be used as compared to a traditional sprinkler system that applies water to a top of a surface of the synthetic field, conserving water while maintaining a cool surface. In some embodiments, a rate at which moisture is accumulated under the turf can be controlled to be substantially similar to a rate at which fibers of the synthetic surface are able to wick moisture without being oversaturated. Thus, the fibers of the synthetic surface may be continuously dampened while excess moisture is not added to the synthetic surface or playing field. As a result of the wicking of the moisture from the bottom, passive evaporative cooling is achieved in combination with active cooling (e.g., cooling achieved by the application of water being cooler than a temperature of the synthetic turf).

The synthetic surface system may include synthetic turf comprising synthetic fibers made from polymers, such as polyethylene, polypropylene, nylon, polyester, or other material as may be appreciated. In some examples, a face fiber composed of a soft and durable nylon fiber may be used. For example, as nylon holds water, the yarn can drip water stored below to be absorbed by the nylon thatch and nylon face fiber, thereby cooling the fiber and reducing the temperature of the fibers and the field. In some examples, an infill may be included.

In some embodiments, the face fiber may include heat and/or solar reflective properties. For instance, in some embodiments, an outer surface of the face fiber may include a coating of a polymer or other material that causes the face fiber to reflect heat and/or sunlight. Also, in some embodiments, an outer surface of the face fiber may include a color that provides heat and/or reflective properties.

In some embodiments, the fibers are hydrophilic and are configured to wick moisture from the elastic sub-layer (shock pad) below. Infill material may be positioned on top and/or in between the fibers, where the infill material may include rubber infill, ethylene-propylene-diene (EPDM) rubber infill, sand infill, cork infill, mulch infill, coconut shell infill, thermoplastic elastomer (TPE) infill, hydrophilic synthetic infill textured fibbers, thatch fibers or a combination thereof or any material that can absorb a certain amount of moisture.

The infill material may act as a ballast to the synthetic surface and/or include a grip material for players to maintain proper traction on the synthetic surface. In additional embodiments, the infill material may include a material that holds moisture such as vermiculite. In some applications for non-infill turf systems, the thatch fibers may be used in place of an infill material.

The synthetic surface may include a synthetic athletic field surface, where the synthetic surface may include a plurality of face fibers of a first length attached in rows to the first sheet in an orientation substantially normal to the first surface of the first sheet, a plurality of thatch fibers of a second length attached to the first sheet and disposed between the rows of the face fibers, a second sheet with a first surface, wherein the first surface of the second sheet is attached to a second surface of the first sheet.

Accordingly, various embodiments for a shock pad that may be combined with other similar shock pads to form an elastic sub-layer of an athletic field, or other surface, are disclosed. A system may include a synthetic surface comprising an elastic sub-layer, where the elastic sub-layer comprises a plurality of shock pads configured to interlock to one another. Individual ones of the shock pads comprise an edge having a height taller than a top surface that defines a moisture accumulation region. Synthetic fibers may be positioned above the synthetic surface such that the synthetic fibers wick moisture from the moisture accumulation region, where at least a portion of the synthetic fibers are hydrophilic such that the plurality of synthetic fibers wick the moisture as it is expelled from the moisture accumulation region, thereby cooling at least the portion of the synthetic surface.

In a further embodiment, a system includes a synthetic surface comprising an elastic sub-layer, where the elastic sub-layer comprises a plurality of shock pads configured to interlock to one another. Individual ones of the shock pads comprise an edge having a height taller than a top surface that defines at least one moisture accumulation region. The system further includes a plurality of synthetic fibers positioned above the synthetic surface and an infill material positioned on or near the synthetic fibers. At least one component of the infill material is hydrophilic such that the infill wicks moisture as it is expelled from the at least one moisture accumulation region, thereby cooling at least the portion of the synthetic surface. The infill material may include rubber infill, ethylene-propylene-diene (EPDM) rubber infill, sand infill, cork infill, mulch infill, coconut shell infill, thermoplastic elastomer (TPE) infill, wood chips, wood infill, textured fibbers, thatch fibers, and/or a combination thereof.

Turning now to the drawings, FIG. 1 is a cross-sectional view of a shock absorbing pad, also referred to herein as a shock pad 100, and is shown according to various embodiments without any moisture accumulation. Additionally, FIG. 2 is a cross-sectional view of the shock pad 100 of FIG. 1 having water accumulation, and FIG. 3 is a cross-sectional view of the shock pad 100 of FIG. 1 with saturated water accumulation and water evacuation, as will be described.

Referring to FIGS. 1-3 collectively, according to various embodiments, the shock pad 100 may include top protrusions 105 that are positioned on a top surface of a body 110 of the shock pad 100, and/or bottom protrusions 115 that are positioned on a bottom surface of the body 110 of the shock pad 100. The top protrusions 105 include edges raised from the top surface of the body 110 that define top surface moisture channels 120. For instance, accumulated water or other liquid may flow in the top surface moisture channels 120 between the top protrusions 105. Similarly, the bottom protrusions 115 include edges projecting downward from the bottom surface of the body 110 that define bottom surface moisture channels 125. Accumulated water or other liquid may flow in the bottom surface moisture channels 125 between the bottom protrusions 115.

The shock pad 100 further includes one or more drainage holes 130. In various embodiments, the drainage holes 130 connect the top surface of the shock pad 100 (e.g., top surface moisture channels 120) with a bottom protrusion 115, which includes a downward projecting portion on a bottom surface of the body 110 of the shock pad 100. The drainage hole 130, in some embodiments, does not align a top surface moisture channel 120 with a bottom surface moisture channel 125. For instance, the drainage holes 130 are not within or directly adjacent to a top surface moisture channel 120. Instead, the drainage holes 130 are nested within a raised edge 135 such that the drainage holes 130 connect the top surface of the body 110 with a respective one of the bottom protrusions 115. The raised edge 135 may include a circular-, square-, rectangular-shaped raised edge so long as the ends of the shape touch one another, not permitting water to seep through in a location other than a top of the raised edge 135. In alternative embodiments, the drainage holes 130 may connect the top surface moisture channels 120 with the bottom surface moisture channels 125 in certain situations, as will be described.

As shown in FIGS. 2 and 3, the raised edge 135 permits a certain amount of moisture to be retained on a top surface of the body 110 of the shock pad 100. Notably, moisture may evacuate through the drainage holes 130 when a moisture level of the top surface of the body 110 is higher than a hole or slope perimeter lip (e.g., the raised edge 135). Otherwise, a predetermined amount of moisture is retained on a top surface of the body 110 of the shock pad 100.

Referring next to FIG. 4, a synthetic field 150, forming a synthetic field layer, is shown positioned on top of the shock pad 100. The synthetic field 150 may be directly on top of the shock pad 100, or other intermediary layers may be positioned between the synthetic field and the shock pad 100. The synthetic field 150 may include synthetic fibers 155, such as face fibers having varying lengths, thatch fibers, or a combination thereof. In some embodiments, one or more of the synthetic fibers 155 include a hydrophilic fiber which may be in fluid connection with a moisture accumulation region 140. To this end, the synthetic fibers 155 may wick moisture from one or more of the moisture accumulation regions 140.

For instance, the synthetic fibers 155 may include hydrophilic fibers such that the synthetic fibers 155 wick the moisture as it is expelled from the at least one moisture accumulation region 140, thereby cooling at least the portion of the synthetic field 150 using evaporative cooling, which is a passive type of cooling. As such, the synthetic fibers 155 may be described as being in “fluid connection” with the moisture accumulation region 140 as moisture, such as water, travels from the moisture accumulation region 140 through the synthetic fiber 155 where it is evaporated, causing a cooling effect.

Turning now to FIG. 5, a synthetic fiber system is shown including the synthetic field 150 and infill 170 installed on top of the shock pad 100, for instance, on, on top of, or between the synthetic fibers 155. Again, the synthetic fibers 155 may include at least one hydrophilic fiber. Additionally, the infill 170 may be a hydrophilic infill in accordance with various embodiments described herein.

Moving along to FIG. 6, a synthetic fiber system is shown including the synthetic field 150 and on top of the shock pad 100. The synthetic fiber system may include at least one hydrophilic straight fiber (e.g., synthetic fiber 155), and/or a least one hydrophilic texturized fiber 175 in accordance with various embodiments described herein.

Referring now to FIG. 7, a synthetic fiber system is shown being positioned on top of the shock pad 100. The synthetic fiber system includes at least one hydrophilic straight fiber 155, and/or hydrophilic texturized fiber 175, and/or hydrophilic infill 170 in accordance with various embodiments described herein.

Turning next to FIG. 8, a three-dimensional view of the shock pad 100 is shown. The shock pad 100 may include perimeter lips 180 and a drainage hole perimeter 185 (having a raised edge 135) around each drainage hole 130 in accordance with various embodiments described herein. As shown in FIG. 8, the drainage hole perimeter 185 and the drainage hole 130 are substantially rectangular in shape; however, in alternative embodiments the drainage hole perimeter 185 and the drainage hole 130 may be substantially circular-shaped, square-shaped, star-shaped, or assume another suitable shape. In FIG. 8, the drainage hole 130 is not positioned in any top surface moisture channels 120, but instead replaces three of the top protrusions 105. The shock pads 100 may connect to one another using male and female projections, respectively, as it known in the art.

In various embodiments, the shock pad 100 may be molded, for instance, using polypropylene or similar material(s). For instance, in some embodiments, the shock pad 100 may be formed of open-cell or closed-cell polypropylene beads. The polypropylene may have a density of approximately one to three pounds per cubic foot molded into the shock pad 100 with a density of between about one to three pounds per cubic foot, in some embodiments. The disclosure is not intended to be limited to these ranges, and other materials and ranges may be employed.

The various exemplary embodiments of the present invention include a self-cooling artificial turf system. In some embodiments, the self-cooling artificial turf system includes a foundation (not shown) along with the synthetic fibers 155 (e.g., grass-like filaments), and the shock pad 100 described herein. The foundation may include one or more of bare ground, stone, gravel, sand, asphalt, cement, and rubber. The synthetic fibers 155 may be attached to a backing layer such that the backing layer is substantially adjacent to the topside of a foundation and such that the synthetic fibers 155 extend substantially upward from the backing layer.
