  • the pallet is preferably moulded in either one or two pieces to define a square that is 2250mm. It is understood however that the square could be larger such as 2400 mm or in some circumstances it is understood that the pallet would be considerably smaller such as a 1250mm square. Essentially, the pallet is usually square, although it can be rectangular, and has side dimensions varying between 1250mm and 2700mm.
  • each pallet comprises two halves 11, 12 that are joined together.
  • One half is shown in Figures 4, 5 and 6 and comprises a top side 22 and an edge side 23 joined by a diagonal 13 that has a pair of spaced recesses 14, 15 and a pair of spaced projections 16, 17.

  • the lower edge 23 of the mould half 11 shown in Figure 6 has a completed corner whilst the other edge 22 of that mould half has an incomplete corner which would be completed by the corner of the other mould half so that about the diagonal one corner is defined by one mould half 11 and the other by the other mould half 12.
  • Each mould half 11 or 12 has a substantially planar upper surface 20 that is supported by a plurality of mutually perpendicular latticework walls 30, 31 that extend down to an open base structure 21.
  • This wall structure is shown with particular reference to Figures 5 and 6.
  • the density of the lattice work wall structure provides adequate support for the planar surface 20 of the pallet 10 and that surface is provided with a plurality of drainage holes 35 that are usually tapered in cross section and are located centrally of each lattice work section as shown in Figure 4.
  • the mould halves 11, 12 are also reinforced by a series of elongate parallel wall structures 36 that are positioned in spaced apart clusters to define as shown in Figure 6 the reinforced walls 37 of rectangular slots 38 that extend along the length of the pallet from both sides to define a pair of spaced parallel slots 38, 39 for access of forklift tines.
  • the top edge of Figure 4 shows how the reinforced wall structure of each tine slot is slightly flared outwardly to facilitate tine entry.
  • each side of the pallet 10 is reinforced by an edge retainer 50 shown in Figures 7-9.
  • the edge retainer 50 comprises a vertical wall 51, the upper half 52 of which is part of the peripheral rim of the pallet 10 and the lower half 53 of which includes an aperture 54 through which a fastener can enable the edge retainer 50 to be screwed to the edge of the pallet 10.

  • the upper half 52 of the wall 51 extends above the upper surface of the mould halves by 81mm to accommodate and locate natural turf that it located in the pallet.
  • the pallet 10 is moulded to have detachable edge retainers 50. It is however understood that the pallet could be moulded to have no edge retainers at all as shown in Figure 14a or to have a fixed integrally formed edge retainer 101 shown in Figure 12 or as a base unit 104 to facilitate attachment of an edge retainer 102 through screws 103 as shown in Figure 13.
  • the pallet 105 is moulded to have an inbuilt slot 106 that is inclined at 15° to the vertical inboard of the side edge of the pallet and to be approximately 25mm in depth with a width of 2mm.

  • a lmm HDPE retaining strip 111 30mm in depth protrudes 6mm above the top and is screwed to the MylarTM strip by three retaining screws 112 shown in Figure 14a.
  • a folded strip 115 of MylarTM having a 30mm, 15° upward projection is secured to the top surface of the pallet 105 by staples 109.
  • this pallet 105 is used to support artificial turf that extends to a height of 62mm above the top of the pallet with an infill of sand and rubber being 40mm in depth.
  • the MylarTM strip 110 prevents escape of the infill when the pallet 105 is transported.
  • Each corner locator 70 is shown in Figures 10 and 11 and comprises a planar surface 71 that has a central crossed pair of raised walls 72, 73 and in each corner a frusto- conical stud 74. As shown in Figures 1 and 2, the corner of the pallet 10 engages within the open channel defined by the raised walls 72, 73 the frusto-conical stud 74 locates in a recess 75 in the underside of the pallet 10. In this way, each locator can accommodate the four corners of four adjacent pallets that are positioned in close proximity to each other.
  • the raised walls 72, 73 of each locator 70 thus defines the spacing of the pallets that varies slightly for natural and synthetic turf.
  • the pallet halves and the locators, as well as the edge retainers, are moulded in foamed HDPE.
  • the upper surface 20 of the pallet 10 is provided with tapered drainage holes 35 positioned adjacent the wall structures and towards the centre of each lattice work structure.
  • the upper surface 20 also includes carpet dimples 45 to assist in location of synthetic turf.
  • Synthetic turf is usually in the form of a nylon carpet with tufts located in a base structure. It is usual to fill the carpet with an aggregate of sand and rubber to define the playing surface.
  • a fine cloth is usually placed over the upper surface 20 of the pallet 10 onto which the turf product can be directly laid.
  • the natural turf usually comprises a grass root zone on a layer of sand/peat reinforced with plastics mesh inserts known as
  • the pallet 10 is usually 140mm in depth and the natural turf extends to a further 125mm above the upper surface of the pallet.
  • the upstanding walls of the edge retainers 50 support natural turf for 81mm.
  • the artificial turf is usually 50mm-60mm above the upper surface 25 of the pallet 10 and it is thus understood that, when used with both artificial and natural turf, suitable lifting means may have to be incorporated within the pallet to raise it to the height to ensure that the artificial turf is at the same level as the natural turf.
  • the pallet 10 when unladen weighs approximately 70lbs and the pallet is designed to be a square of 2.29 metres.
  • the pallet is preferably constructed from structural foam using commingled plastics, foamed through the use of Nitrogen gas .
  • the commingled plastics is a mixture of some or all of the following: High Density Polyethylene (HDPE), Low Density Polyethylene, Polypropylene, fibres, ABS, and long fibres for reinforcement.
  • the pallet when unladen weighs approximately 70lbs to 1501bs depending on the plastics mixture used and the pallet is designed to be a square of 2.29 metres.
  • the pallet described above is moulded in foamed plastics using lancing technology. Nitrogen gas is used to expand the plastics to produce a micro cellular arrangement, thereby substantially lightening the structure. This technique also allows the use of commingled plastics.
  • High Density Polyethylene is viewed as the most suitable plastics and this provides a structure that is sufficiently strong to withstand the loads that will be subjected to both natural and artificial turf.
  • the plastics can have the gas mixture varied to enhance impact, strength and flexibility.
  • the plastics can also be recycled plastics.
  • the lattice work structure defined by the wall structure of the pallet halves provides a good drainage facility whilst excellent aeration for the root structure of natural turf that may be located above the pallet.
  • the open structure of the underside of the pallet ensures that there is no likelihood of the pallet aquaplaning on a smooth surface.
  • the pallets described above have to satisfy two important criteria, namely the structures need to be sufficiently flexible to ensure that they lay flat on the support surface that is usually a slab of concrete. This is especially the case when used to support artificial turf that is considerably lighter than natural turf. With artificial turf, it is very important that the corners of each pallet do not arch upwardly. It is also important that there is no wobble. To solve this problem it is proposed in the embodiment shown in Figures 15a and 15b to provide slots 120 in the adjoining edges of the four adjacent pallets 10 that make up a corner to accommodate a pin 121 that extends across the edges of the four pallets and prevents the edges of the pallets arching upwardly at the join. The slots would be approximately 10mm wide and 25mm deep to extend about 155mm in length.
  • Slots may also be positioned midway along the sides of each pallet and circular locking discs may be used instead of the pins to lock four adjacent corners in the manner shown in Figure 15 (a) or to allow panels to be in offset rows like brickwork with the disc engaging two adjacent corners of pallets in one row and the middle of the side of one pallet in the adjacent row.
  • the open structure of the underside of the pallet provides a flexible construction that can accommodate the uneven and possibly rough surface of the supporting substrate that is usually a concrete slab.
  • the moulding of the pallet in a foamed plastic can by variation of the mix increase this flexibility to ensure a flat even support without the problem of wobbling.
  • Another important characteristic of turf assemblies of the kind described above is the impact resistance, especially when used with sports such as the various kinds of football i.e. soccer, football or rugby.
  • There is a known impact resistance test that is measured by a cleg hammer tested with a 2.25kg hammer at a drop height of 450mm. This impact resistance is measured in gravity units and it is generally viewed that an acceptable impact resistance is between 40-70 gravity units whilst resistance of 110 or more is too severe and likely to cause injury. The tests have been carried out to compare the impact resistance from the following combinations :
  • FIGs 16 and 17 illustrate mechanisms that facilitate vertical lifting.
  • each pallet is provided with a lifting lug connection 130 in each corner of the pallet.
  • Two options of the lug connection 130 are shown in Figure 16c that can be either between a cross web and a side flange in the join between the web and the side flange.
  • Figure 16b shows a tool 131 that has a handle 132 that is joined to an elongate shaft 133 that terminates in a head 135.
  • the head has a T shaped end to enable it to be inserted into the locator 130 and then turned through 90° to engage the underside of the locator. With four such tools engaging each corner of the pallet 10 it is possible to lift the pallet 10 and turf product without the use of forklift tines.
  • a cork screw style device 210 that has a annular end 211 that is adapted to engage a bar 212 by screwing the corkscrew style device into the turf 222 the coils of the screw engage and grip the turf 222 and then by placing the bar 222 through a series of these devices 210 that are arranged in parallel and lifting the bars the whole turf product can be lifted either clear of the pallet or, if the turf is attached to the pallet, with the pallet.
  • the corkscrew device 210 instead of simply screwing into the turf could, in certain circumstances, screw through the turf to engage the pallet thereby ensuring lift of both the pallet and the turf without necessarily having to attach the turf to the pallet.
  • the pallet structure described above is sufficiently light yet durable to withstand the impacts and stresses of use, to provide ready support for the turf when used as a playing field whilst at the same time providing a means for facilitation transportation and storage of turf, especially natural turf which can be transported to a suitable site for regrowth.
  • the versatility of the pallet described above especially with its capacity to support natural and or artificial turf and the capacity of individually identifying each pallet and storing this information in a computer allows a stadium to manage the placement of its turf .
  • the computer can monitor the use time and wear assessment of the turf and select appropriate pallets for movement to even out wear characteristics and maximize utilization of the total field. Movement of the pallets also facilitates offsite application of lines or coloured images such as sponsor's logos prior to installation in the stadium. It is understood that the system facilitates the ability to pick up and move pallets as desired, thus when a stadium is for multipurpose use all the turf can be removed exposing the concrete base for concerts and like entertainment and when there is a need for sporting venue the turf can be moved back to the stadium. In the interim the artificial turf can be stacked in racks and the natural turf can be taken to a position of optimum growth,
  • the design of the pallets is such that natural turf can be left on the pallet and stored with adequate drainage being provided under the pallet to provide optimum growth especially in an environment that encourages growth in contrast to environments usually provided by a stadium where cantilevered stands block out sunlight and retard growth of natural turf .
  • a sophisticated conveyor system is envisaged that would automatically transport the pallets to both a racked storage facility for artificial turf and a nursery position for natural turf.
  • the turfing option described above allows stadiums to be designed without the need to have roof systems that can open and close. These systems are very expensive to build and to maintain and are merely a compromise .
  • a closed roof provides the optimum conditions for stadium use and with the ability to simply and effectively remove the turf the problems associated with a closed roof are overcome. It is estimated that installation of natural turf can be completed within twelve hours using pallets of the kind described above and it similarly takes about eight hours to totally remove the turf units allowing the stadium to be used for other functions that would be based on the underlying concrete floor.
