Definitions

  • the invention relates to a device for the temporary recovery of surfaces having the advantage of being, thanks to a desmodromic winding means, put in place or removed very quickly.
  • the covering device differs from these old devices by the fact that the winding drum is mobile and that its movement is favored by the use of mobile guide carriages also.
  • One or more of these carriages can advantageously be fitted with mechanical or electrical drive means.
  • the device becomes completely autonomous and does not require any attachment point on the ground to be covered.
  • the device consists of a canvas fixed by one of its ends temporarily flush with the ground to be protected, this canvas being wound on a drum supported by a shaft mounted in bearings provided on two end carriages comprising each at least one front wheel and one rear wheel rolling one on the ground to be protected and the other on the canvas while each carriage carries tension wheels or rollers maintaining the centering of each carriage and therefore the tension of the canvas when winding or unwinding it on the ground.
  • Fig. 1 is a perspective view of part of a tennis court on which the covering device of the invention is installed.
  • Fig. 2 shows a side elevation of one of the motor carriages, knowing that in this embodiment, the movement is obtained by one or more motors located inside the winding tube of the fabric.
  • Fig. 2a is a partial front elevation of FIG. 2.
  • Fig. 3 shows an end view of one of the motor carriages, knowing that in this embodiment the movement is obtained for the displacement of the winding tube by means of cranks, chains and bevel gears.
  • Fig. 3a is a partial front elevation corresponding to FIG. 3.
  • Fig. 4 shows in plan one of the ends of the device and shows the possibility of installing one of the carriages at a certain distance from the edge of the protective fabric so that despite the state of the ground made wet and soft outside the protection limit the wheels of the trolley run in an area protected from rain by the fabric.
  • the floor of a tennis court 1 is partially covered on either side of the net 2 of fabrics 3, 3 'unrolled by the tubes 4, 4' resting on the ground.
  • the shafts 5, 5 'of the motors (not shown) embedded in the tubes 4, 4' are mounted non-pivotally by means of the carriage arms 6, 6 'held in position substantially parallel to the ground by wheels 7, 7' resting on the canvas and by wheels 8, 8 'resting on the ground at a certain distance from the edge 9, 9' of the canvas due to spacer pins 10, 10 '.
  • Cradles 11, 11 ' maintain the spacing at the other end of the carriage and can advantageously support adjustable rollers 12, 12' for centering the assembly.
  • the power supply to the motors is obtained by electric wires passing along the edge 9, 9 ′ of the fabric.
  • These flexible wires also serve as stiffeners.
  • Other flexible stiffeners nylon thread, steel cable, etc.
  • nylon thread, steel cable, etc. can also be arranged by any suitable means in certain places of the fabrics.
  • the ends opposite to the unwinding tubes are advantageously held at the bottom of the ground by straps 13 attached to the fabric 3 and to the fence 14 of the ground.
  • the tube 4, in the fabric winding position 3 disposed on the ground 1 is moved by the built-in motor, the shaft 5 of which is mounted in a bearing secured to the arm 6 of the carriage.
  • the wheel 7 then bears on the fabric 3, thus reacting to the engine torque, while the wheel 8 is released from the ground.
  • the tension wheels or rollers 12, adjustable relative to their support 11, maintain the centering of the carriage relative to the tube 4.
  • the arrangement of the wheels 7 can be seen with respect to the end of the tube 4 and at the edge 9 of the fabric 3 which, thanks to the length of the axle-spacers 10, allows these wheels to circulate in the covered part of the ground, therefore dry, the reference 13 designates the entry motor power supply.
  • the device for driving the tube 4 is constituted by a set of sprockets and chains 15 placed at the ends of the tube 4, these sprockets and chains being driven by a pair of bevel sprockets 16 driving a shaft 17 of length slightly greater than that of the tube 4. Rods 18 ensure the tension of the chains 15.
  • a return system and cranks 19 makes it possible to obtain the rotational movement of the assembly which is supported by carriages 20 connected to each other by a spacer 21.
  • the wheels 7 and 8 also bear on the canvas 3 and soil 1.
  • the rotation of the motor shaft 5 driving the tube 4 carrying the protective fabric 3 can also be obtained using a crankshaft and a transmission shaft or even, instead of the deflection system and cranks 19, by an internal combustion engine or the like.
  • the motor 22 supplied by an electric wire 122 located at the edge 9 of the fabric 3 is outside the tube.
  • the drive thereof is then obtained by a gear train 23 located at the ends of the tube 4.
  • the winding and unwinding of the fabric 3 can be obtained by simple pushing or pulling exerted on the carriage carrying the protective fabric 3.
  • the wheels 7 of the carriage become driving in order to '' directly or indirectly drive the shaft 5 carrying the drum 4 on which the fabric 3 is wound.
  • the shaft 5 of the drum 4 which in principle consists of a light alloy tube allowing easy transport can be temporarily weighed down by filling with water, sand or other fluid elements which are placed inside the sealed hollow part of the drum tube.
