Definitions

  • the present invention relates to a shading system with a Tuchbehang which can be wound on a winding shaft which is rotatable within a veneer, wherein the Tuchbehang is deflected over a rounded support member.
  • the supporting element is provided in a conventional veneer with a lower exit slot within the veneer, which acts based on the winding layers on the winding shaft at the top of Tuchbehangs and counteract wrinkling due to sagging of the winding shaft.
  • the support element is located below the winding shaft, wherein the curtain runs quasi between the winding shaft and the support element due to the intervention of the support member at the top thereof. This arrangement results in a fairly large amount of veneer and there remains a gap on the winding shaft, through which dirt can accumulate within the veneer.
  • the support member is formed as a rotatable guide roller, which in turn acts on the top of Tuchbehangs, based on the winding layer attacks.
  • the roller bearing of the guide shaft is expensive and increases the space required, which due to the two-sided storage of the leadership this bent at correspondingly large Anlagenbreiton again in consequence of their own weight and / or under the action of existing in the curtain tension is, which in turn can lead to wrinkling in the Tuchbehang.
  • the object of the present invention is to provide a shading system that counteracts a simple, space-saving construction wrinkling in the curtain.
  • the object is achieved by a shading system of the type described above, wherein the support element is above the axis of rotation of the winding shaft, based on the winding on the winding shaft on the underside of Tuchbehangs attacks and the wrap angle of Tuchbehang is less than 90 °, said the support member forms the upwardly facing end of a bottom panel of the veneer which supports the support member over its substantially entire length.
  • the inventive design of the shading system offers a number of advantages.
  • the bottom panel extending over the entire length of the support element and the veneer allows a uniform support of the support element, so that it can not bend centrally even under high load and in the case of large system widths, so that wrinkling is optimally avoided. Wrinkles that could form due to a deflection of the winding shaft are stiffened. Due to the arrangement of the support element above the axis of rotation of the winding shaft and the attacking on the underside of Tuchbehangs the space requirement can be minimized at the same time, in addition also the bottom panel with the support element as a conclusion still provides a continuous screen on the winding shaft available, the penetration of Dirt in the veneer effectively prevented.
  • the support of the support element through the bottom panel is preferably carried out on the opposite side of the wrapping area of the curtain to avoid bending elements or at least reduce.
  • the support element has a tubular cross-section.
  • Tube-shaped cross-sections offer a high degree of flexural stiffness with a low dead weight, whereby due to the tubular shape the rounded outer side is provided for deflecting the drapery shade.
  • the tubular cross-section can be supported by the bottom panel on its outer side, but the pipe cross-section can also be designed slotted, the bottom panel then engages through the slot in the support member and this can be supported on the inside of the pipe cross-section over its length.
  • the support member may also be formed by the bent edge of the bottom panel in a particularly simple embodiment of the invention.
  • This variant is particularly simple in construction but can easily absorb the supporting forces occurring without deformation.
  • the bottom panel is formed with its inside as a support surface for a floating mounted winding shaft.
  • the winding shaft is located without lateral support in this embodiment in the curved support surface, wherein the curtain is pulled off via the support member, which also prevents the winding shaft can get out of the Auflagerung. Due to the uniform bearing over its entire length and the deflection of the winding shaft is effectively avoided as a cause of wrinkling.
  • the bottom panel and / or other parts of the veneer may consist of an extruded profile, wherein in the case of a bottom panel which simultaneously forms the support member and the bearing channel, the entire veneer including the support member may consist of a single extruded profile.
  • the winding shaft is inserted laterally into the extruded profile with the drapery and an end rod closing the curtain, and this is then closed by lateral shutters.
  • the bottom panel can also be constructed in several parts and, for example, have at least one substantially horizontal panel part and an upwardly facing from this support member which supports the support member. At the same time, the supporting part also forms the screen, which ensures protection against contamination, as we discussed earlier.
  • At least one pressure strut for stiffening the support member may be provided, which is supported on the horizontal panel part.
  • This pressure strut also expediently extends over the entire length of the support element in order to avoid local deflection.
  • the support part can have a slotted tube cross-section, in which the support part then engages for support.
  • Fig. 1 shows a shading system 10 in the form of a vertical awning.
  • This vertical awning is fixed to a building-side support structure 12 or facade via one or more support brackets 14.
  • a veneer 16 is fixed, which has a front panel 18 and a bottom panel 20, which protect a winding shaft 22 within the veneer.
  • the veneer 16 is bounded on both sides by side walls (not shown) in which bearings and drive elements (not shown) of the winding shaft 22 are arranged, on which a cloth curtain 24 of the awning is wound, which is here extendable vertically downwards.
  • the free end of Tuchbehangs is provided with a designed as a hollow profile end profile 26 which is guided in lateral guide rails 28.
  • Alternative guides of the end profile can also be designed as rod guides or cable guides.
  • the curtain 24 slides with its underside on a support member 30 which is designed as a slotted tubular element 32, wherein a rounded deflection region 34 with a wrap angle smaller 90 ° is formed directly through the outer surface of the tubular element 32.
  • the tubular element 32 is supported by a support member 38 which engages in a slot 36 and forms an upwardly facing end of the bottom panel 20 of the veneer 16.
  • the support member 38 which extends over the entire length of the slotted tubular member 32, is strip-like and can absorb only small bending moments, a likewise strip-like compression strut 40 is provided, which is bolted via a screw 42 to the bottom member 20, wherein the orientation the compression strut 40 substantially corresponds to the leveling force of the resultant force on the tubular element 32 through the appealing curtain 24.
  • the support member 38 also forms a screen and protection against contamination inside the veneer 16th
  • Fig. 1 The upper part of Fig. 1 shown fastening means between the support bracket 14 and the veneer 16 are to be understood as an example and not specifically subject of this application.
  • a shading system 110 which in turn is designed as a vertical awning.
  • the veneer 116 is formed as an extruded profile integral with a front panel 18, a support structure 114 which simultaneously forms the top wall and the rear wall 121 of the veneer 116, and a bottom panel 120, wherein between the rear wall 121 and the bottom panel 120 is a hollow chamber 123 is formed, which stiffens the veneer 116.
  • the bottom panel 120 merges integrally continuously into a support member 138, ie the support member forms an upwardly facing completion of the bottom panel 120, wherein the upper edge of the support member 138 is bent to a tubular cross-section 132, the support member 130 forms the deflection 134th Are defined.
  • the bottom panel 120, the support member 138 and an inner wall 125 of the hollow chamber 123 is formed with a continuous radius, which serves as a support surface 127 for a here stored floating winding shaft 122.
  • a continuous radius which serves as a support surface 127 for a here stored floating winding shaft 122.
  • an assembly of the winding shaft with the wound Tuchbehang 124 by lateral Finschieben and subsequent closing of the veneer 116 is provided by lateral aperture elements or side walls.
  • a free space 129 is provided, which occupies an end profile 126 with retracted curtain.
  • This end profile 126 is the only opening of the veneer 116, so that the wound Tuchbehang is well protected when not using the shading system 110 from dirt.
  • An inlet bevel 131 at the lower end of the front panel 118 ensures that the frontal profile 126 arrives safely in the closed position, while on the opposite side of the radius of the support member 138 and the bottom panel 120 ensures that the front rail 126 from the inside Pulling up against the front panel 118 applies.
