Definitions

  • the invention relates to a device for screening off a space, comprising
  • the most usual devices comprise a screen, which is lowered by means of a traction cable device connected to the upper edge of the screen and is rolled on a winding element at the bottom of the device. This winding element may be driven manually or automatically.
  • a rolling screen for darkening an opening applied in the wall of a building is described in FR 25 63 860.
  • the problem of such a device is that when raising or lowering the screen occurs at a lower speed than rolling or unrolling the winding element, high tensile stresses may occur.
  • the screen may be lowered or raised more rapidly than the speed of rolling and unrolling of the winding element, sagging of the screen may be prevented.
  • a ventilation curtain where winding occurs at the bottom, for stables and the like.
  • a temperature controlled transmission motor is connected to a winding shaft and to a cord system.
  • the curtain is connected to the winding shaft and at the top to a supporting batten, which is connected to the cord system.
  • the connection to the winding shaft occurs through a universal joint and the connection to the cord system occurs by means of reversing rollers.
  • the tube for winding the cord system is tapered.
  • the varying circumferential velocity per turn may be compensated when the curtain, at the bottom, is wound and unwound on and from a winding tube firmly mounted on bearings and because of which the diameter of this lower winding tube is permanently varying.
  • roller systems comprise a long tube-shaped roller, which may be connected to the extremity of the roller for rotatably attaching the extremity of the rollers opposite the window.
  • the screen is wound and unwound from the rollers, while they are rotating around their respective longitudinal axis.
  • a drive is provided for driving the roller in one direction or the other, in order to wind the screen from one of the rollers unto the other.
  • the purpose of the invention is to provide a device for screening off a space, not having the disadvantages mentioned above and where for each type of device therefore, the flexible screen is kept stretched both when winding and unwinding.
  • a device for screening off a space comprising:
  • the screen will be stretched for both winding and unwinding.
  • the said two elements rotatable with respect to one another are shafts, each provided with a gearwheel, the gearwheels having matching teeth and grooves.
  • the shaft situated on the side of the winding element is connected to this winding element by means of a slidable universal joint, because of which the force of said shaft is transmitted to the winding element by means of the slidable universal joint.
  • said transmission means comprise a conical drum unto which a cord is wound and unwound, this cord being connected to the said second element, in such a manner that the winding movement of the winding element will move up and down the second element, because of which the screen will be moved up and down in order to shut off the said space entirely or partly.
  • the said second element is a second winding element and is designed for winding and unwinding the screen, the said space being entirely shut off and the said transmission means comprise a chain which is connected to the said second winding element, in such a manner that because of the winding movement of the winding element, the second winding element performs a winding and unwinding movement, because of which the screen is rolled or unrolled from the one winding element unto the other winding element.
  • a flexible screen (3) is provided being wound and unwound at the bottom by means of a roller system (5) driven by a drive unit for, in its closed position, screening off a space (2) entirely or partly.
  • the roller system (5) is provided with a winding element in the form of a winding roller (6), which is designed to wind and unwind the screen (3).
  • a second element is provided, i.e. a tube (7), which is attached to the screen (3).
  • a cord (8) is provided on this tube (7), which is wound and unwound from a conical drum (10) by means of a pulley system (9).
  • This conical drum (10), the pulley system (9) and the cord (8) constitute the transmission means ensuring the winding movement of the winding element (6) to be transferred into an up and down movement (A) of the screen (3).
  • an upper roller system is provided as a second element in addition to the lower roller system.
  • the screen (3) has a length, which is longer than the distance (X) between the upper and the lower roller system (5).
  • the upper or the lower roller system (5) is provided with an upper or a lower winding element respectively in the form of a winding roller (6) which is provided in order to roll and to unroll the screen (3).
  • transmission means are provided, comprising a chain which has been provided on the upper and lower winding rollers (6). In this manner the screen (3) will be unwound from the one winding roller and wound onto the other winding roller and the other way round. Therefore the winding movement of the lower winding roller (6) is converted into a winding movement of the upper winding roller.
  • connection means (11) have been provided between the said winding roller (6) and the said transmission means. At least at one of the two extremities (12a, 12b), these connection means (11) are installed to be rotatable in a firm connection with the space (2) to be screened off. Preferably, this is the extremity (12b), being situated on the drive side. More preferably, the connection means (11) on both extremities (12a, 12b) are installed to be rotatable in a firm connection, as represented in figure 1.
  • the firm connection is a holder (13), which is provided with roller brackets in which the winding roller (6) may rotate and which is installed on a fixed support of the space (2), which has to be screened off.
  • the winding roller (6) is likewise installed in a holder (4), which is provided with roller brackets in which the winding roller (6) may rotate.
  • the other extremity (12b) of the connection means (11) is rotatably installed in a motor block (14) in which a motor has been applied for driving the device (1). However, the device (1) may also be driven manually.
  • the other extremity (12b) of the connection means (1) being also installed in a holder, which is provided with roller brackets.
  • connection means (11) are provided with two elements, rotatable with respect to one another, in the form of two shafts (15a, 15b) , i.e. a first shaft (15a) on the side of the winding roller (6) and a second shaft (15b) on the side of the conical drum (10).
  • Each of the two shafts (15a, 15b) is provided with a gearwheel (16a, 16b), the gearwheels (16a, 16b) having matching teeth and grooves.
  • the second shaft (15b) is provided with spring means in the form of a spiral spring (18) which is wound around this shaft and which, when unrolling the screen (3), will exert a spring force on the said shaft (15b), which is working in a direction opposite to the force causing the angular displacement (arrows B) of the rotating shafts (15a, 15b).
  • spring means in the form of a spiral spring (18) which is wound around this shaft and which, when unrolling the screen (3), will exert a spring force on the said shaft (15b), which is working in a direction opposite to the force causing the angular displacement (arrows B) of the rotating shafts (15a, 15b).
  • the second shaft (15b) is connected to this winding roller (6) by means of a sliding universal joint (17), because of which the force of said shaft (15b) is transmitted to the winding roller (6) through the sliding universal joint (17).
