Definitions

  • the invention relates to a roller shutter drive, in particular for shading devices, with a roller shutter armor which is guided along an inclined surface to be shaded and which can be wound up and unwound from a motor-driven, rotatably mounted winding shaft.
  • winding shaft is each slidably guided on the end faces on guideways which run obliquely downwards in the assembled state, and in that the downward movement of the winding shaft due to gravity is limited by a guide sliding element arrangement, which is different from the winding shaft unwinding roller shutter armor is guided along this guide sliding element arrangement to the inclined surface.
  • the winding shaft Due to the slidable guide in the guideways, the winding shaft is always due to gravity on the guide sliding element arrangement, regardless of the respective diameter due to the more or less wound up roller shutter armor, so that the roller shutter armor remains tangentially in contact with this guide sliding element arrangement during unwinding and along it Inclined surface is guided. As a result, a sufficient pushing force is exerted on the unrolling roller shutter armor by the winding shaft, so that the roller shutter armor is safely unwound even with very slight inclinations of the inclined surface to the horizontal of, for example, 5 °.
  • the constructive measures required for this are simple and inexpensive to implement. This unwinding process works with both fully wound and almost unwound roller shutter armor.
  • the guide sliding element arrangement preferably consists of at least two cam-type guide sliding elements which are arranged in the axial positions of the edge regions of the winding shaft, with long winding shafts being able to provide at least a third guide element for supporting and guiding the axial central region.
  • cam-like guide sliding elements can be made relatively narrow be so that, despite good guidance, a small amount of friction is caused between them and the roller shutter curtain.
  • the roller shutter armor is provided on the edge with adhesive and / or toothing elements that mutually fix its winding layers, which are designed in particular as plug-in elements that can be inserted into the hollow slats of the roller shutter armor on the edge or as strip-like adhesive layer elements on the roller shutter armor.
  • adhesive and / or toothing elements advantageously consist of elastic material with a high coefficient of friction and / or have teeth or corrugations running perpendicular to the winding direction.
  • the adhesive and / or toothing elements must not axially overlap with the guide sliding element arrangement but rather must run next to it in order to be in the region of this guide sliding element arrangement to be able to realize a low coefficient of friction.
  • the inclination of the guideways can be adjusted as a function of the inclination of the inclined surface by means of an inclination adjustment device, since a certain assigned inclination of the guideways has been found to be optimal for each inclination of the inclined surface.
  • a structurally simple solution for realizing a suitable inclination adjustment device consists in that the guideways designed as guide rails are pivotably mounted on holding elements, in particular designed as holding plates, rows of holes or elongated holes being provided on the holding elements to adjust the angle of inclination of the guideways, so that a simple Bolt, rivet or screw fastening for fixing the guide rails with the specified angle of inclination are possible.
  • the holding elements are expediently attached to the two end faces of a roller shutter box.
  • the guide sliding elements of the guide sliding element arrangement are each arranged at a distance from the end faces of the roller shutter box and also contribute to the mechanical stability of the roller shutter box.
  • the guide sliding elements open advantageously at a passage slot of the roller shutter box, so that there is a continuous guidance of the shutter curtain up to this passage slot.
  • brackets provided with rollers are arranged on the two end faces thereof, the rollers each being guided in the guideways, which in particular have a C-shaped cross section, so that the rollers only in the Movement direction can be moved, and with minimal friction.
  • One of the two holders is preferably connected to the winding shaft via a rotary bearing, and the other holder is connected to the drive shaft or the housing of a drive motor arranged within the winding shaft in a rotationally fixed manner.
  • a roller shutter box 10 has an essentially square cross section and has a slot-like opening 11 which extends in the longitudinal direction and through which a roller shutter curtain 12 can be guided out of the roller shutter box 10.
  • the roller shutter drive described is particularly suitable for shading devices in which window surfaces or glass roofs are to be shaded, which have a relatively small angle of inclination ⁇ to the horizontal.
  • the roller shutter drive according to the invention already works at angles of inclination of approximately 5 °.
  • a holding plate 14 On the inner surfaces of the two end walls 13 of the roller shutter box 10, a holding plate 14 is fixed in each case by means of screws 15 or other holding means.
  • a guide rail 16 On each holding plate 14 a guide rail 16 is pivotally mounted about an axis 17, this guide rail 16 according to FIG. 3 having a cross section in the form of an angular C. From the axis 17, a shorter region of the guide rail 16 extends obliquely upwards and a longer region obliquely downwards into a region of the roller shutter box 10 that is distant from the opening 11.
  • An inclination adjustment device is used to set a desired angle of inclination of the guide rail 16.
  • This consists of two through holes 18 in the guide rail 16 on both sides of the axis 17 and two rows of adjustment holes 19 in the holding plates 14, which are arranged in a circle around the axis 17 and from this have the same distance as the through holes 18.
  • the through holes 18 are made to coincide with two of the adjusting holes 19 at the desired angle of inclination and are fixed in this position by means of screws 20 or bolts or rivets.
  • the screws 20 are loosened, a new angle of inclination is set, and the screws 20 are then inserted or screwed in again through the through holes 18 and the adjustment holes corresponding to the other angle of inclination.
  • Other known tilt adjustment devices can of course also be used here.
  • a cylindrical tubular winding shaft 21 is provided on both end faces with rod-like brackets 22, 23 which extend transversely to the longitudinal axis of the winding shaft 21 and at both ends of the winding shaft 21 wear pioneering roles 24.
  • These rollers 24 each consist of a support body 26 fixed to the respective holder 22, 23 by means of retaining screws 25, a roller ring body 27 being rotatably mounted on each support body 26 by means of bearing balls 28.
  • the holder 22 shown on the left in FIG. 2 is rotatably supported via a central axis 29 with a rotary bearing 30 fixed in the winding shaft 21.
  • the pivot bearing 30 is fixed in a holding body 31 inside the winding shaft 21.
  • an electric drive motor 32 is inserted and fixed, which is only shown in part.
  • the central axis 29 of the holder 23 is rotatably connected to a drive shaft 33 of the drive motor 32.
  • a coupling piece 34 is used for this purpose.
  • the housing of the drive motor 32 can also be connected in a rotationally fixed manner to the holder 23, for example screwed onto it, while the drive shaft 33 pointing inside the winding shaft is connected in a rotationally fixed manner to the winding shaft 21 by means of a driver.
  • the winding shaft 21 is arranged in the roller shutter box 10 such that the rollers 24 arranged at the opposite end regions are each guided in pairs in the guide rails 16, as shown in FIG. 3 and also indicated in FIG. 1. In this way, the winding shaft 21 can be moved in the roller shutter box 10 along the guide rails 16. As a result of the force of gravity, however, the winding shaft 21 will assume the lowest possible position along the downwardly inclined guide rails 16. This lowest possible position is due to two cam-like ones Guide sliding elements 35 are determined, which are fixed at a distance from the two end walls 13 of the roller shutter box 10 and parallel to these end walls 13 in the roller shutter box 10.
  • These guide sliding elements 35 have an arcuate inner surface or edge pointing towards the winding shaft 21, the circular curvature continuously merging into a linear region 36 leading to the opening 11.
  • the region 37 of the roller shutter curtain 12 which is wound on the winding shaft 21 is therefore constantly in contact with the two guide sliding elements 35 due to gravity.
  • the roller shutter curtain 12 consists in a manner known per se from parallel, lined-up slats 38, which are interlocked with one another via longitudinal toothing 39, as shown in FIG.
  • the slats 38 are designed in a manner known per se as hollow profile elements.
  • plug-in elements 40 on the end, the plug-in area 41 of which is inserted into such a cavity, the outer area 42 in each case somewhat overlapping the slat 38 lying next to it.
  • Smaller insertion elements 43 are each arranged between two overlapping insertion elements 40 or inserted into the respective lamella 38.
  • the outer areas 42 of the insertion elements 40, 43 have corrugations or teeth running parallel to the longitudinal direction of the lamella 38.
  • the insertion elements 40, 43 consist of an elastic material with a high coefficient of friction, with only one these measures can be provided.
  • strip-like adhesive layers made of elastic material can also be applied to the edge of the roller shutter curtain, which can also have a corresponding corrugation.
  • the individual adhesive stiffening elements on the slats in turn cause the layers to be mutually fixed and prevent the layers from shifting relative to one another.
  • the drive motor 32 is switched on in the unwinding direction, the winding shaft 21 rotates with the wound area 37, and the roller shutter curtain 12 is moved along the guide sliding elements 35 by the Winding shaft 21 pushed away towards opening 11, as a result of which, due to the toothed insertion elements 40, 43 (or adhesive strip elements), a high thrust force is generated which also permits the already mentioned small inclination angles ⁇ .
  • the roller shutter curtain 12 is guided along the surface to be shaded on the edge side in guides, not shown, in a manner known per se. Moves when unwinding the winding shaft 21 due to the shrinking wound area 37 along the guide rails 16 towards the guide sliding elements 35. A reverse movement of the winding shaft 21 along the guide rails 16 takes place during the winding up due to the increasing wound area 37.
  • the setting of the inclination of the guide rails 16 depends not least on the inclination angle ⁇ and is optimized according to the individual requirements.
  • the guide sliding elements 35 must each be arranged at least so far from the end walls 13 of the roller shutter box 10 that the insertion elements 40, 43 with their corrugation and / or their high coefficient of friction do not slide on them, but rather the smooth areas of the slats 38.
  • an additional guide sliding element 35 or a plurality of additional guide sliding elements 35 can be arranged in the central region of the roller shutter box 10 in order to prevent the winding shaft 21 from sagging.
  • An area 44 of the guide sliding elements 35 which is formed in one piece or as shown in FIG. 1, supplements its inner edge or surface to form an almost complete circle, an end area engaging in the slot-shaped opening 11 from above and lifting the roller shutter curtain from the linear area 36 of the guide sliding elements 35 only allows to a small extent.
