Definitions

  • An artificial surface capable of being rolled and un- 7 39, 60 rolled is formed with flexible strips which prevent damage to the surface when said surface is unro11ed [56] References Cited over a supporting substrate.
  • the present invention relates to a large one-piece artificial surfacing suitable for covering and uncovering a base surface which may be rolled and unrolled without damage to it.
  • FIG. 1 is a side elevational view showing the loops formed when a conventionally wound, resilient, artificial playing surfacing is unrolled from a core.
  • FIG. 2 is a side elevational view of the roll of FIG. 1 showing the collapsed loop formed as the surfacing is unrolled.
  • FIG. 3 is a top view of a roll of artificial surfacing employing the present invention being wound on a core.
  • FIG. 4 is a side elevational view of the roll of artificial surfacing of FIG. 3 being unwound from its core.
  • FIG. 5 is an end view of an artificial surfacing having flexible strips embedded therein in accordance with this invention.
  • FIG. 6 is a perspective view of the surfacing of FIG. 5 wound on a core.
  • the loop 13 When the leading loop 13 reaches a sufficiently large size, the loop will collapse as shown in FIG. 2.
  • the surfacing Because of the large weights associated with artificial surfacings, in some cases up to tons, the surfacing is subject to damage by tearing, creasing, or deforming, e.g., stretching when the remaining roll of surfacing is rolled over the collapsed loop with further unwinding. The resulting damage may result in a surfacing unsuitable for use, e.g., athletic contests, and require time and expense to repair.
  • the present invention eliminates the problems noted with reference to FIGS. 1 and 2.
  • thin, normally straight, flexible strips 16 of wood, plastic, metal or some combination of two or more of these materials are laid lengthwise along the length of the surfacing 10 prior to winding the surfacing and the core 12 in forming a roll 17.
  • the strips 16 are laid on top of the surfacing 10 parallel to one another at spaced intervals across the width of the surfacing. This is done prior to winding the surfacing 10 on the core 12 with the strips extending for the major portion of the length of the surfacing.
  • each strip is a continuous piece, but a plurality of shorter length and laid more or less end-to-end to make the desired length.
  • the surfacing 16 is then wound on the core 12 to form a roll 17 with the strips being interposed between the convolutions of the surfacing 10 on the roll 17.
  • an artificial surfacing 19 made in accordance with the invention is shown.
  • the surfacing comprises a resilient matrix 20 of synthetic or rubbery material having an artificial grass or the like 21 on the top surface thereof.
  • Embedded within or otherwise attached to the undersurface thereof are strips 16. Again, these strips are parallel to one another and spaced across the width of the surfacing.
  • the strips are a part of the surfacing itself and need not be removed when the surfacing is unwound from its roll and laid in place. The function of the strips is as described with reference to FIGS. 3 and 4.
  • FIG. 6 shows the surfacing of FIG. wound into roll form on a core 12.
  • the weight of the resilient artificial surface; the inherent strength of the resilient artificial surface; the physical properties of the flexible strips, e.g., yield strength, width, thickness, and the desired spacing between strips are all considered when designing an artificial surface which will not be subject to damage during unrolling.
  • materials suitable for supporting a loop while unrolling artificial surfaces are carbon spring steel, fiberglass, polyesters and fiberglass-polyester laminates.
  • the presently preferred material is a 1095 carbon spring steel which combines flexibility with good yield strength.
  • the flexible strips may be placed parallel to the unrolling direction at varying separations depending upon the weight of the surface being unrolled and the strength of the flexible strips.
  • a heavy artificial surface such as the Tartan Turf brand artificial turf of the Minnesota Mining and Manufacturing Co., which has a weight of about 1.8 lb./ft. and a thickness of up to about 34-inch, 3/32 inch thick spring steel strips placed on 10-12 foot centers will adequately support the loop formed during unrolling.
  • a thinner material, e.g., l/l6 inch thick steel strip, is easier to handle, but
  • the flexible strips may be corrugated longitudinally to produce a stiffer material capable of supporting greater loads.
  • the flexible strips need not run the entire length of the surfacing since most artificial surfacing has sufficient inherent strength to support a loop of modest size while being unwound from a roll. Collapse of the loop becomes a problem only after a substantial amount of artificial surface has been unrolled, e.g., 50 feet or more, when the loops formed will be of substantial size.
  • the flexible strips can be placed so as to be active only during the final portion of the unrolling procedure. Using strips which are only 2/3 the length of the field to be unrolled, the strips could be placed so as to be active only during the final 2/3 of the unrolling cycle.
  • the cross sectional configuration of the strip is not critical but flat strips are more easily placed on or embedded in an artificial surface.
  • the loop formed during unrolling is largest during the final revolution of the core and the physical properties necessary for the strips to support this loop can be readily determined for each surfacing from the diameter of the core, the weight per unit area of the surfacing and the maximum loop size.
  • a large, one-piece storable artificial surface suitable for covering a supporting substrate, said artificial surface capable of being rolled and unrolled without damage due to the collapse of loops formed during unrolling of the surface to cover said substrate comprising:
  • At least one flexible resilient strip convolutely interposed between convolutions of said surface said strip supporting and preventing the collapse of loops formed during unwinding of the roll thereby preventing the necessity of rolling said surface over a collapsed loop and damaging said artificial surface.
  • a large, one-piece storable artificial surface sutiable for covering a supporting substrate, said artificial surface capable of being rolled and unrolled without damage due to the collapse of loops formed during unrolling of the surface to cover said substrate comprising:
  • At least one flexible resilient strip imbedded in said surface said strip supporting and preventing the collapse of loops formed during unwinding of the roll thereby preventing said surface from rolling over a collapsed loop and the resulting damage to said artificial surface.
  • the storable artificial surface of claim 2 having a plurality of flexible strips.
