Definitions

  • the invention relates to a roller shutter with the features of the preamble of claim 1.
  • Exterior windows and doors are known to form the zones in which the greatest heat losses occur when air conditioning buildings. It is also known that such heat losses can be reduced by a roller shutter armor, which is attached - preferably on the outside of the window and door openings - in such a way that it can cover the entire corresponding opening.
  • the roller shutter curtain is usually guided laterally in the roller shutter tracks and, after completely lowering, sits with its lower edge on the window sill or door sill, so that the individual, articulated profile bars that form the roller shutter curtain slide over one another in such a way that a certain seal is made between the individual bars.
  • a roller shutter box is attached, in which a horizontally running winding roller, which can be driven to rotate, is mounted.
  • the roller shutter box is disadvantageously high.
  • the invention creates a roller shutter in which two roller shutter curtains arranged parallel to one another, each guided in guide rails, assume the same height with their respective lower edge both in the upper and in the lower position.
  • This is to be achieved according to the invention by a particularly simple and, in particular, adjustable and readjustable device, so that the invention creates a particularly good thermal insulation of window or door openings with simple means, without the clear height of this opening being cut in any noteworthy manner, or particularly large installation depth or height is required for the roller shutter box.
  • the invention achieves this by means of the characterizing features of claim 1.
  • two roller armatures are wound one on top of the other on a single winding roller.
  • the top of the first roller shutter curtain which forms the first winding layer when it is wound up, is fastened to the winding roller with its upper edge.
  • the upper edge of the second, additional roller shutter curtain which forms a second layer between the layers of the first roller shutter curtain when it is wound up, is fastened to the lower side of a flexible connecting element, which in turn is fastened to the winding roller with its upper side.
  • This connecting link is capable of transmitting tensile forces essentially without elongation, but, on the other hand, immediately deviates due to its flexibility in the action of compressive forces or pushing forces with the formation of a loose loop.
  • this connecting member is dimensioned such that when the double roller shutter is pulled up, the lower edges or the end strips of the two roller shutter curtains attached there are at the same height at the upper end of their path of movement. Becomes now the double roller shutter is lowered, then, as already described above, the second roller shutter armor moves faster than the first roller shutter armor and thus arrives first with its lower edge at the lower end of its path of movement. As the take-up roller rotates further, this second roller shutter curtain remains at rest, while the first roller shutter curtain moves further down to its end position. During this last movement section, the lower end of the connecting member is already at a standstill, while the upper end attached to the winding roller continues to move in the circumferential direction thereof. As a result, the connecting member dodges without a force transmission between the second roller shutter curtain and the take-up roller. This means that the take-up roller can continue to rotate unhindered until the first roller shutter curtain has reached its end position.
  • the sequence of movements described above takes place in reverse order: first, the first roller shutter armature moves upwards, while the connecting element pulls taut. Then both roller shutter curtains move at different speeds, whereby the later rolling shutter curtain that has just started has caught up with the lower edge of the first up to the upper end of the path of movement of the two curtain curtains.
  • each mutual relative position of the two lower edges of the roller shutter curtain can be adjusted. It is thus possible that the outer roller shutter curtain with its lower edge overlaps the inner one to achieve better thermal insulation.
  • the length of the connecting link can be determined constructively from the outset. According to one embodiment of the invention, however, it is advantageous that the length is adjustable in order to permit installation and manufacture with high tolerances and yet to be able to adjust the double roller shutters according to the invention after installation in such a way that the cleanly aligned closure of the two lower edges of the individual Roller shutter curtain is possible in its upper end position.
  • the connecting link consists of at least two belts which are located on the upper edge of the second roller shutter curtain or are attached to the take-up roller.
  • the two roller shutter curtains with the same division, i.e. that is, to produce from profile bars with the same profile in each case.
  • the first roller shutter curtain has a smaller pitch than the second; wherein in particular the second roller shutter curtain has a normal division, while the division of the first roller shutter curtain is chosen to be smaller than usual.
  • Such a small roller shutter division results in a smaller, possible winding radius for the first roller shutter curtain forming the first layer during winding, so that the diameter of the winding roller with wound roller shutter curtains is further reduced by this inventive feature.
  • roller shutter armor with a correspondingly suitable thickness, then it is possible to replace already existing single roller shutters by the double roller shutter according to the invention simply by replacing the winding roller, roller shutter armor and its lateral guidance by corresponding elements according to the invention.
  • the weatherproof roller shutter armor must withstand the wind pressure that occurs, while the thickness of the inner roller shutter armor can be largely reduced.
  • the outer roller shutter curtain for example from stiff metal profiles
  • the inner roller shutter curtain can be formed from heat-insulating plastic according to a further embodiment of the invention.
  • the double roller shutter shown has a winding roller 1 which can be rotated in the direction of the arrow (FIG. 1) for winding up a first roller shutter armor 3 and a second roller shutter armor 5 and in the direction opposite to the arrow for unwinding the wound roller shutter armor 3, 5 (FIG. 2).
  • the first roller shutter curtain is fixed at point 2 on the circumference of the winding roller 1.
  • the second roller shutter curtain 5 is attached with its upper end 6 to two belts 7, which are attached with their other end at point 8 on the circumference of the winding roller 1. In this case, the belts 7 overlap the first roller shutter curtain 3 from the outside.
  • two guide rails 9 are arranged vertically, namely one on each side of the two roller shutter curtains 3, 5.
  • the guide rail 9 has two longitudinally extending guide grooves of different widths, as will be explained in more detail below.
  • an inlet area 11 is provided, which allows the two roller shutter curtains 3, 5 to run in with little wear and noise.
  • An end strip 13 is arranged on the underside of the first roller shutter curtain.
  • an end strip 14 is arranged on the underside of the second roller shutter curtain 5.
  • Each of the two roller shutter curtains 3, 5 is composed of individual links 4 (tanks 3) and 12 (tanks 5), each of which is formed from a plastic hollow profile rod, the upper and lower sides of which are articulated into the next higher or lower link 4, 12 intervene.
  • the cladding has an average thickness d, a length in the roller shutter running direction 1 and an associated guide groove width w, while the links 13 of the second roller shutter armor have an average thickness D, a height L and an associated slot width W. All mentioned values of the links 12 are considerably larger than those of the links 4. Otherwise, the cross sections of the two links 4, 12 are essentially similar.
  • the members 12 and the shutter armor 5 form the outside or weather side, so that they have to have certain minimum dimensions to withstand the wind pressure, efforts to penetrate and the like.
  • the inner, first roller shutter armor 3, takes on the task of additional thermal insulation, is therefore arranged at a distance from the second roller shutter armor 5 and consists of relatively slender links in order to take up as little space as possible when winding onto the winding roller 1.
  • the double roller shutter In the operating position shown in FIG. 1, the double roller shutter is closed, with both end strips 13, 14 resting on the window sill 10.
  • the take-up roller 1 assumes a position into which it was brought under the force of gravity of the inner, first roller shutter armor 3.
  • the outer, second roller shutter curtain 5 has already reached the window sill 10 with its lower end strip 14; at this point, the belts 7, starting from the upper end 6 of the second armor 5, were placed tightly around the winding roller 1, the fastening point 8 for the belts 7 being offset in the direction of the arrow with respect to the illustration in FIG. 1.
  • the end bar 13 of the first tank 3 has not yet reached the window sill 10, and thus continues to drive the roller 1 against the direction of the arrow for rotation. This rotation comes to a standstill when the first tank 3 has come to a standstill by sitting on its bar 13.
  • the fastening point 8 for the belts 7 has shifted further in the direction of rotation (counter to the direction of the arrow), so that the belts 7 are spread apart in an arc. It is advantageous here that the straps 7 are not able to transmit pressure or thrust loads, but are sufficiently stiff to bulge when such a load occurs. If the straps were 7 slack, they could hang down and get tangled under certain circumstances.
  • the take-up roller 1 is rotated in the direction of the arrow in the state shown in FIG. 1, then the first shell 3 is immediately pulled upwards, while the second shell 5 remains in its position, until the belts 7 are tight around the Winding roller 1 or the first winding layer, which is already located there and consists of the first shell 3, is pulled around. Only then does the second tank 5 move. Since there is always a larger winding radius for this second tank 5 than for a corresponding section of the first tank 3, this second tank 5 will move upward at a higher speed than the first tank 3, whereby that Advance dimension of the first tank 3 or the length of the belts 7 is dimensioned such that at the upper end of the range of motion of the two tanks 3, 5 the position shown in FIG. 2 has just been reached.
  • the second roller shutter curtain 5 can not be made much lighter than a conventional roller shutter curtain for a single roller shutter for reasons of stability, there is a higher torque for rotating the winding roller 1 against the direction of the arrow than for the comparable single roller shutter, since this torque also means that Weight of the first roller shutter curtain 3 contributes.
  • the two roller shutter curtains 3, 5 do not touch the lower stop 10 at the same time, a relatively gentle run-out takes place at the end of the range of motion, which prevents the winding roller 1, which is always slightly braked anyway, from over rotating and thereby leads to faults.
  • the winding roller 1 shown in FIG. 2, on which the two roller shutter curtains 3, 5 are wound has a radius R which is not significantly larger than the corresponding radius of a winding roller for a single roller curtain because of the relatively small dimensions of the first roller shutter curtain 3 Roller shutters, since the winding roller 1 shown has a winding body radius r which is smaller by about the thickness d for the members 4 of the first roller shutter armor 3 than the permissible minimum radius for winding the second roller shutter armor 5, the members 12 of which have the dimension usually used .
  • the links 4 of the first shell 3 have a concave curvature with a smaller radius on their inside facing the winding roller 1 than the links 12 of the second shell 5 in order to ensure the trouble-free function even then len if the named, unusually small bobbin radius r is used.
  • the radius of curvature of the links 4 corresponds essentially to the radius r mentioned.
  • the links 4 also have a larger radius on their outside facing the second shell 5, which essentially corresponds to the radius of curvature of the concave inside of the links 12.
