Definitions

  • This invention relates to a device for shielding off wheather conditions, such as for shielding off rain, cold, wind or sun, for instance in or around constructions having open access to the outside.
  • the expression "having open access to the outside” refers to those constructions where proper ventilation is achieved by leaving large openings in the outer walls of the construction or even by deleting (part of) those outer walls, such as in particular with large stock and/or cattle breeding buildings, where such open access is required by regulation.
  • the outer diameter of the upper roll and of the lower roll i.e. the diameter of the beam with the canvass and the reinforcement profiles
  • the diameter of both empty beams is for instance 100 mm
  • the diameter of completely wound up beam, with the canvass and the reinforcements will typically be around 350 - 400 mm.
  • winding the protective canvass from the one beam on the other both rotate with a different speed which is constantly changing.
  • winding the protective canvass from the one beam on the other both rotate with a different speed which is constantly changing.
  • a comparable problem occurs also when winding the canvass from the lower beam to the upper beam.
  • a further problem lies in maintaining a proper and substantially constant tension on the canvass during winding and after winding.
  • the purpose of this invention is to provide a shielding device which avoids the problems involved with the known devices, which offers entirely adaptable screening off possibilities for open buildings of any height and length, and which allows to properly stretch the screen and to maintain it properly stretched.
  • the invention therefor provides a shielding device, comprising means for unrolling and rolling a protective sheet from, repectively on two winding bodies, and means for maintaining the unrolled sheet substantially flat between said two winding bodies, wherein the means for unrolling and rolling the protective sheet comprise a separate hydraulic motor acting on each winding body, and a regulation system causing the hydraulic motor of a winding body to perform a driving action when the winding body is rolling up the protective sheet and causing the motor of a winding body to perform a braking action when the winding body is unrolling the protective sheet.
  • the regulation system of the hydraulic motors preferably comprises hydraulic pumping means, a hydraulic circuit connecting the hydraulic motors and the hydraulic pump, and hydraulic regulation valves on the hydraulic circuit.
  • the regulation system according to this embodiment of the invention most preferably comprises means for controling the hydraulic regulation valves on the hydraulic circuit.
  • These control means may for instance consist of electric, electro-magnetic, pneumatic or electronic means.
  • the protective sheet may suitably comprise several (at least two) sections of different types of sheet material.
  • the sheet material may consist of any flexible surface of textile material, non-woven material and/or foil or film material, or the like; the type of material and its properties (thickness, permeability, opacity, etc.) are thereby selected in function of the ability of the material to partially or substantially reduce the ingress of wind, sun and/or cold, etc., and/or to avoid the ingress of rain in the protected space.
  • the bodies on which the protective sheet are wound may suitably consist of cylindrical beams or tubes.
  • the means for maintaining the unrolled sheet substantially flat may suitably comprise tensionning and/or reinforcement bars or profiles provided transverally with respect to the winding direction of the sheet material (i.e. parallel to the winding body or beam on which they are rolled together with the protective sheet).
  • the shielding device shown on figure 1 comprises a protective sheet, globally designated with reference numeral (1), an upper winding tube (2) and a lower winding tube (3) for rolling and unrolling the sheet (1), tensionning and/or reinforcement bars / profiles (4) for maintaining the unrolled sheet substantially flat, and guiding plugs (5) provided to said bars (4) to guide these bars (4) along frame elements (6), (7).
  • the protective sheet shown on figure 1 comprises three sections (8), (9) and (10) of different sheet material, more specifically a first section (8) of relatively light fabric, a second section (9) of more dense fabric or canvass, shown with a window (11) of transparent film material, and a third section (10) of relatively close and opaque structure.
  • the frame construction of the device, comprising frame elements (6), (7), is completed by two further frame elements or profiles (12), (13) and four connecting plates (14).
  • the winding tubes (2), (3) are supported by support elements (16), respectively (17). These support elements (16), (17) also support guiding rolls (18) respectively (19), for the winding tubes (2), (3).
  • the support elements (16), repectively (17), are assembled to the upper, repectively lower connecting plates (14) by means of bolts (not represented), bolted through the holes in plates (16) and (17) and in plates (14).
  • the winding rolls (2), (3) are controlled by means of a hydraulic system shematically indicated with reference numeral (20) on figure 1.
  • the sheet In order to use the lower part of the protective sheet, i.e. a section (10) of relatively closer and/or more opaque structure, the sheet is wound up on the upper tube and unwound from the lower tube. This may for instance be the case in the cold season or at night (situation shown at left on figure 2).
  • the upper part of the protective sheet i.e. a section (8) of relatively light fabric
  • the sheet In order to use the upper part of the protective sheet, i.e. a section (8) of relatively light fabric, the sheet is unwound from the upper tube and wound up on the lower tube. This may for instance be the case in the hot season (situation shown at right on figure 2).
  • the intermediate part of the protective sheet i.e. a section (9) of intermediate properties between the relatively light fabric of section (8) and the relatively dense structure of section (10), may for instance be used in intermediate situations, such as in the middle seasons (situation shown in the middle on figure 2).
  • the hydraulic system (20) shown in this figure 3 comprises: an oil tank (21) provided with
  • an additional separate manifold block (26) can be connected to the manifold (31).
  • the excess pressure valve (34) achieves that when for some reason the device becomes blocked the hydromotors will not tear to pieces the various parts of the construction.
  • the electrovalve (37) makes the hydromotors turn in one or the other direction. When actuating one of the directions the brakes connected to the hydromotor will be uncoupled via the line indicated in dotted line.
  • One motor operates always directly at the pressure of the excess pressure valve (34). This is the hydromotor operating the beam on which the sheet is to be rolled at that moment.
  • the other motor will receive reduced pressure via pressure reduction valve (40). This is the motor for the sheet which is being unrolled. This creates a braking force so that the sheet remains stretched.
  • one hydromotor (41) will be turning while the other motor (41) will serve as a brake.
  • the braking takes place by braking or restraining the oil circulating in the conducts of the non driven / driving motor by means of a regulation valve, and by circulating said oil.
  • both hydraulic motors do not have to take account of each others revolution speed.
  • a brake is provided to block both winding tubes so that the protective sheet remains properly stretched and under tension.
