Definitions

  • the present invention relates to an automatic apparatus for covering fields, particularly sports pitches.
  • US-A-4,399,954 discloses an apparatus for covering fields with large sections of artificial turf, with the turf being winded on a roll.
  • the known apparatus provides for winding/unwinding means, including a motor which activates the two drive rollers and supporting the unwound roll and a winch.
  • winding/unwinding means including a motor which activates the two drive rollers and supporting the unwound roll and a winch.
  • folding and unfolding of the turf roll entails serious problems due to the large dimension of the turf involved and its inherent weight.
  • the aim of the present invention is to overcome the above-mentioned problems by providing an automatic apparatus for covering fields, in particular sports pitches, which is easy to use, rapid in function, and which does not require the presence of a large number of personnel.
  • a scope of the invention is to provide an automatic apparatus for covering fields, in particular sports pitches, which permits the arrangement of a large space, visible even from as great distance, on which can be placed messages such as publicity.
  • the reference numeral 1 designates the automatic apparatus for covering fields 2, in particular sports pitches, and comprises a sheet 3 constituted by a plurality of modular strips 4, each equipped with thermal heating devices essentially constituted by short circuit inductive resistances defining interconnected members 5, made of metal net having a mesh which can be electrified and being inserted "sandwich-like" between two sheets of elastic-plastic material constituting each of the strips 4.
  • the strips are activatable and slideable with respect to each other through winding and/or unwinding means 6, concealably housed in respective pits 7, parallel to the sides of the pitch 2.
  • Said means 6 comprise, at a first side of said pitch, a plurality of pulleys 8 located at each of the strips 4 and being motorized in rotation by a plurality of synchronously activatable motors-motor reducers 9 provided with clutch devices, not illustrated in the drawing figures, for disengagement purposes.
  • wound cables 10 or the like which can be coupled at their free end 4a of each strip 4.
  • said means 6 are constituted by a series of drums 11 keyed to parallel, horizontal shafts 12, which are rotatably motorized with respective members 13.
  • the drums 11 are placed in contact engagement with underlying pairs of rollers 14 having axes parallel to the axes of the drums, on which are wound the strips 4 and which are preferably keyed to two parallel horizontal shafts arranged, when viewed in plan, in a staggered manner.
  • each strip 4 is wound on its respective drum 11, located in a concealed manner in a corresponding pit 7 provided with a protective cover 15, so as not to constitute a danger for players who run out of the area of play.
  • one or more operators manually hook the cables 10 to the ends 4a of the strips 4, and successively actuate the motors-motor reducers 9 which rotatively drive the pulleys 8, either directly if the pulleys are keyed to the vertical drive shafts of the motors, or through transmissions 16, in the instance that these are supported on horizontally rotatable shafts.
  • the cables 10 are thus wound onto the pulleys 8 and entrain, preferably in the transverse direction of the pitch 2, all of the strips 4 until they constitute the sheet 3 covering the entire pitch 2.
  • an energy source can be connected via the terminals 18 to the net members 5, to cause heating of the mesh of the net and consequent heating of the surface of the pitch 2 which, when soaked, will tend to dry rapidly.
  • the invention achieves the proposed aim and objects.
  • each strip could, for summer use, be perforated to allow rapid evaporation of humidity.
