Definitions

  • the subject of the present invention is the production of a sports field, especially a tennis court or mini-court, of a removable and transportable type which can be installed easily, temporarily or durably, on any surface. horizontal.
  • the sports field in particular a tennis court or mini-court, is made up of a set of panels assembled together using connecting elements, this set of panels being placed on a horizontal surface or on natural soil.
  • the removable assembly thus produced can be installed, for example, during the summer season on football fields and mountain rinks then unused and, during the winter season, on clay tennis courts or more generally on any other land temporarily or permanently available.
  • the sports field according to the invention in particular a tennis court or mini-tennis court, consists of a set of removable panels linked together by connecting means acting on the width and on the length of the panels by opposing the possible tendency of the panels to deform, and it is characterized in that the panels rest on the ground by means of plates of insulating material which are of a height such that they prevent the level of standing water from reach the level of the panels, the connecting means for assembling the panels having a horizontal part which is fixed to the underside of the edges facing two adjacent panels and a vertical part housed under the panels by means of the interposition of the plates insulating, said connecting means being oriented longitudinally and transversely.
  • the panels used according to the invention can advantageously be produced using weather-resistant materials for outdoor use on the ground.
  • the panels can in particular be. made using special plywood, possibly coated with a waterproof and non-slip surface product.
  • each connecting element is produced in the form of a U-shaped slide in the horizontal upper part of which are formed openings intended to allow its fixing, for example by screwing , at the opposite edges of the undersides of two adjacent panels to be assembled.
  • the vertical parts may have at their lower end a horizontal return directed inwards, giving the slide an omega profile.
  • edges of the adjacent panels, in the assembled position are spaced apart from each other by a small distance and, in the free space thus provided, the horizontal face of the connecting element has openings to allow the flow of the rainwater at the periphery of each of the panels.
  • each connecting element is constituted by two angles, the horizontal wings of which are fixed to the underside of the edges facing two adjacent panels and the vertical wings of which face each other are secured together, by example by welding or bolting.
  • the edges of the adjacent panels, as well as the vertical assembly wings of the angles fixed to these panels are spaced a small distance to allow the evacuation of rainwater.
  • FIG. 1 there is shown in 1, the natural soil, previously leveled and possibly slightly compacted. Leveling can advantageously be carried out using an addition of sand, sand or anything else.
  • a textile sheet 2 On the ground 1 is disposed a textile sheet 2 forming an insulating layer permeable to water but impermeable to the elements constituting the ground and thus preventing these elements from rising.
  • insulating plates 3 made of polystyrene, polyurethane or a similar material, with a thickness of the order of about 20 millimeters.
  • a panel 4 made of a weather-resistant material for outdoor court use.
  • the panel 4 can in particular be produced using a special plywood optionally coated with a waterproof and non-slip surface product.
  • connection elements 5 each constituted by a metal profile having an upper horizontal part 6 continuing, on each side, by a vertical part 7 having at its lower end a horizontal return 8 oriented inward, so that the connecting element 5 has an omega profile.
  • the connecting element 5 is arranged below the adjacent edges of two panels 4, in the space 9 left free by the insulating plates 3.
  • the upper face 6 is then fixed to the underside of the adjacent panels 4 by screws 10 passing through openings 11 in the panels 4 and holes 12 with incorporated nut formed in the upper face 6 of the element 5.
  • This fixing could however be done by any other appropriate means, for example using clips.
  • the adjacent edges of these are spaced a small distance 13 (which may be of the order of 5 millimeters) in the extension of which the upper face 6 of the element 5 has openings 14 allowing the flow of rainwater to the ground.
  • the connecting elements 5 in addition to their assembly role, also have a role of stiffeners by opposing the deformation forces of the panels 4 which may remain despite the arrangement of the insulating plates. 3. Arranged longitudinally and transversely, the connecting elements 5 prevent deformation of the panels 4 across the width and over the length.
  • FIG. 3 and 4 there is shown the natural floor 1, the textile sheet 2 permeable to water, the insulating plates 3 and the panels 4.
  • the connection between the panels 4 is provided by metal angles 15, the upper face of the horizontal wing 16 of the angle 15 being fixed to the lower face of the panel 4 while the vertical wing 17 of the angle, directed downwards, is intended to be made integral, by bolting in the example shown , the vertical wing 17 opposite the angle 15 fixed to the adjacent panel 4.
  • the horizontal wing of the angle 15 is fixed to the underside of the panel 4, for example, using screws 18 cooperating with nuts 19 prefixed to the angle, but it could be carried out by any other suitable means, if necessary, using clips or other systems.
  • angles 15 which also play the role of stiffeners, are arranged longitudinally and transversely, as can be seen in FIG. 4, preventing the deformations of the panels 4 over the width and over the length. It is understood that, for a better understanding of this figure, the panels 4 were torn off and that in reality each insulating plate 3 supports a panel 4 to which the angles 15 are fixed.
  • a small space 20 (which may be of the order of 5 millimeters) is provided between the panels 4 and a space of the same order is provided between the vertical wings of the angles 15 in order to allow a flow of rainwater through the construction then through the permeable fabric 2.
