    description
    BUILDING OPENING SHADING DEVICE AND COMPENSATING RING THEREFOR
    The invention relates to a Gebäudeöffnungsverschattungsvorrichtung according to the preamble of claim 1, as well as a suitable compensation ring.
    Such building opening shading device, such as vertical awnings, have for shading and / or insect protection on windows and / or door openings existing on a web material curtain, so for example, a cloth or textile web or a mesh fabric web. The curtain is wound up on a winding shaft which is usually rotatably mounted in a box above the building opening and can, if required, be lowered in front of the window and / or the door opening. On both sides of the building opening guide rails are arranged for the curtain, which begin above the building opening and run down. The cloths or textiles used as hangings are forcibly guided laterally in the guide rails during a movement in front of the building opening and have edge thickenings along their two side edges, for example a zipper half. In the guide rails in each case a guide channel for the associated edge thickening is formed with a curtain facing the longitudinal slot, which is penetrated by the facing edge of the curtain and narrower than the edge thickening.
    Due to the greater thickness of the edge thickenings (e.g., the zipper halves) than the hanger fabric, such a wipe can not be wound on a shaft or shaft without tensions and wrinkles when it has a constant diameter over its entire width.
    Because by the tension applied during winding, which acts on the curtain because of the gravity of an end bar at the bottom of the cloth or curtain, the superimposed cloth webs are pressed tightly together. The edge thickening are forcibly forced with a corresponding force to a larger winding diameter. This leads to overstretching, material fatigue and damage to the bonds in the region of the edge thickening and / or the transition region.
    The generic state of the art is that the winding shaft is designed to be reduced in diameter below the area of the edge thickenings, i. E. that the winding shaft has a smaller cross-sectional area in compensation areas in which the edge thickenings come to lie when the curtain is wound up than in a cloth area located therebetween. Such a vertical awning can be found in the French patent application FR 2 886 332 A1 and also in the US patent application US 2012/0012260 A1. The excess winding volume thus has the possibility to avoid this space.
    However, the evasion of the excess volume in the reduced diameter area happens irregularly and depending on the number of windings and the applied tensile stress with different characteristics. The result is more or less tightly folded and inwardly directed folds which correspond more closely to the increasing number of turns.
    Since now linger the textiles for a long time in the wound state on the shaft or axis, the wrinkles gradually emboss in the cloth or the curtain. After the cloth has been lowered, these folds become visible and adversely affect the visual appearance. With increasing use of the cloth (ascents and descents), the wrinkles can also lead to a material damage and thus to a deterioration of the service life.
    On this basis, the present invention seeks to provide a Gebäudeöffnungsverschattungsvorrichtung in which these disadvantages are eliminated, and to provide a compensation ring for this, with which this can be accomplished.
    This object is achieved with regard to the building opening shading device by the features of claim 1, with regard to the compensating ring having the features of claim 9.
    According to the invention it is provided that the outer circumference of the winding shaft extends in each cross-section in the compensation areas along a curve in circulation around a winding shaft axis in the radial direction and decay curve. According to the invention, a compensating ring which can be lowered onto the winding shaft is furthermore provided, for example in the form of an end cap which can be plugged into the end face or into a winding shaft profile or a sleeve which is laterally attached to a shaft journal of the winding shaft. The compensation ring forms one of the compensation areas of the winding shaft under the edge thickenings of the wrapped curtain.
    On the winding shaft so, preferably over two such compensating rings, radially in the compensation areas a defined alternative space provided, depending on the application, for example, between 5% and 50%, so that the wound in wound up there coming or wound edge thickening after can dodge inside. However, this evasive volume is not distributed rotationally symmetrically around the circumference, but is provided in the form of a volume reserve which is defined by the curve which predetermines the outer circumferential contour of the winding shaft and curves in the radial direction over the circumference.
    The cloth or curtain sets so with its edge thickening in the predetermined by the outer contour of the compensation areas, distributed over the circumference evasive chambers or areas. As a result, the sharp kinks of the cloth are avoided and distributed to a resulting from the outer peripheral contour number smaller, predetermined by the design of the outer peripheral contour deformations with a smooth contour.
    Supporting the winding shaft in the compensation areas each have a circumferential, the outer periphery of the winding shaft in the compensation area forming Tuchanlageabschnitt, which preferably consists of an elastic material such as foam rubber. But even rigid material would be conceivable. Correspondingly, the compensating ring may also preferably be made of the elastic material, at least in a region forming the cloth contacting section. The compensating ring may thus be formed, for example, as an end cap for the end face of the winding shaft or as a sleeve which can be pulled up on a shaft journal and preferably made of the elastic material or comprise a carrier which preferably has a cloth attachment ring made of the elastic material and the shaping according to the invention.
    In this case, the compensation areas of the winding shaft or the compensating rings can be formed with a uniform outer circumferential contour along the winding shaft. Each cross section of the winding shaft then has the same outer contour in the compensation areas.
    In another embodiment, the winding shaft or the compensating ring on the side facing the guide rails outside of the respective compensation area, the cross section with the over the circumference in the radial direction and decay curve following outer contour. The outer contour of the cross section of the winding shaft in the compensation areas can then proceed in the course along the winding shaft inwardly over free-form surfaces in the outer contour of the winding shaft in lying between the compensation areas cloth area, ie on a substantially circular outer contour.
    Advantageously, the winding shaft or have the compensating rings in the compensation area a - as explained above, either constant or with transitions -cross-section with a polygonally shaped outer contour, so for example a five- or hexagonal outer contour.
    It is understood that the number of corners of the polygon depending on the thickness difference between the curtain and the edge thickening, the number of wound fabric layers, the material properties of the cloth or the edge thickening, and the tensile stress occurring in the cloth can be suitably selected.
    In terms of a possibly even lower wrinkling, it would also be conceivable to round the outer contour there forming polygonal, for example in the form of a circumferential sine wave with a corresponding number convex, radially outwardly projecting antinodes, to an even softer outer contour with even smaller deformations of the cloth effect. Also designed as a uniform thickness outer contour would be conceivable.
    Advantageous embodiments of the invention will be explained below with reference to the accompanying drawings.

FIG. 2 shows a horizontal section through one of the guide rails of the vertical awning shown in FIG. Figure 3 shows an inserted in the guide rails of Figure 2 additional rail with engaging curtain, Figure 4 is a vertical section through the arrangement of Figure 3, Figure 5 is a schematic view of an insect screen according to a Ausfüh tion form of the invention at drape, FIGS. 6-8 show alternative embodiments of a winding shaft according to the invention with one as

    Main field of application of the invention are so-called vertical awnings. However, the invention is not limited thereto. Other orientations, such as horizontal or inclined, etc., are conceivable, as they occur for example in roof shading etc. The alignment is arbitrary.
    Likewise, it should be noted that the curtain of an arrangement according to the invention, although mostly consists of a textile sheet material, that advantages of the invention, however, also result in all other limp, surface or web-shaped materials. In this sense, the indication of hanging should therefore be understood.
    Reference will now first be made to FIG. 1. Vertical awnings are usually arranged on the outside of a window inserted in a building opening, etc. The vertical awning shown in Figure 1 includes a generally arranged in the region of the upper edge of the building opening box 1, protrude from the side guide rails 2 down. Within the box 1 is a rotatably mounted, driven in the direction of rotation winding shaft 3, on which a web-shaped, consisting of an awning curtain 4 wound, or from which this curtain 4 is unwound. The curtain 4 is accordingly attached with its upper end to the winding shaft 3. At the lower end of the curtain 4, a drop bar 5 is attached, which may be provided with weight weights and is guided by the guide rails 2.
    The curtain 4 passes through a provided in the bottom of the box 1, over the box length continuous, slot-shaped outlet opening 7. The guide rails 2 extend with their upper ends at least to the outlet opening 7 or protrude beyond this something in the box 1 into it.
    The box 1 contains on its front sides two suitable prepared as moldings caps, which may be provided with downwardly projecting pin for connection of the guide rails 2. The winding shaft 3 is mounted on the caps. The interior of the box 1 can, as shown, be delimited by a circumferential jacket, the ends of which are attached to the visor caps. The jacket here comprises, for example, an inner or a rear wall 10, as well as an upper part 11 integrally formed therewith and an outer or front wall 12.
    The box 1 of the vertical awning shown in Figures 1 and 2 is provided for Unterputzeinbau provided in the masonry or an insulating layer of the building opening in which the front wall 12 is correspondingly plastered over or covered with material and thus no longer accessible after installation is. The winding shaft 3 should also remain accessible after installation for maintenance and inspection purposes. For this purpose, the bottom of the box 1 together with the outlet opening 7 is designed as a total inspection opening.
    In order to cover the inspection opening except for the outlet opening 7, a revision cover assembly 13, 14 is provided. The inspection cover assembly 13, 14 has an audit close to the building interior inspection cover 14 which extends between the rear wall 10 and the outlet opening 7, and a building interior distant, as hinged to the front wall 12 flap designed additional inspection cover 13 extending from the outlet opening. 7 extends to the front wall 12.
    In the guide rails 2 are, as shown in Figures 2 and 3 in particular, the lateral guidance of the curtain 4 serving additional rails 25 are used, which are supported transversely to the running direction of the curtain by elastic buffer elements 26 on the respective associated guide rail 2. On the lower ends of the guide rails 2 caps can be attached, which have suitable recesses for the lower end of the associated additional rail 25, whereby they are fixed at its lower end. On the upper end of the additional rails 25 inlet funnel can be plugged, which ensure a reliable inlet of the lateral edges of the curtain 4 in the additional rails 25.
    The additional rails 25 include, as Figures 2 and 3 show, a vertical guide channel 30 which is accessible via a vertical, that is in the running direction of the curtain 4 longitudinal slot 31. The longitudinal slots 31 of the additional rails 25 face each other, so that the curtain 4 with its lateral edges, the slots 31 passes through and engages with its lateral edge thickenings 32 in the guide channels 30 of the lateral additional rails 25.
    The engaging in the guide channels 30 edge thickening 32 of the curtain 4 are, as shown in FIG. 4, expediently formed by zippers along the side edges of the curtain 4 zippered belts or zipper halves attached there, wherein the existing metal or plastic hooks of the zipper form the edge thickening or edge bead, so that there is a kederartiger engagement, as indicated in Figure 3.
    This measure not only ensures reliable guidance but also causes a straight winding of the curtain 4 on the winding shaft. 3
    Due to the edge thickening 32 of the curtain 4, the wound on the winding shaft 3 curtain 4 at its two side edges on a greater thickness than in the intermediate cloth area. In the prior art, as shown in FIGS. 11 and 12, diametrically reduced sleeves are drawn onto the winding shaft 103 in the compensating regions 119, in which the edge thickenings 32 come to rest with the curtain 4 wound, in order to provide a compensating volume for to create the edge thickenings 32. This, however, led to the formation of wrinkles 121 shown in FIG. 12, the wrinkling, however, not following any specific regularities, but proceeding in an uncontrolled manner.
    In order to prevent this, no rotationally symmetrical outer contours are now selected according to the invention in the compensation areas of the winding shaft, but those which have in circulation around the winding shaft axis in the radial direction and decay section, ie distributed over the circumference evasion volume or chambers, in which the cloth can invest in the outer contour, so that it no longer comes to an uncontrolled wrinkling.
    FIG. 13 shows a winding shaft end with a compensating sleeve 19a or a compensating ring 19a mounted on the end-side shaft journal, which has a polygonal, more precisely hexagonal outer contour and thus six such compensating chambers 21a for the curtain 4.
    Figures 6 to 8 show various alternatives for the configuration of the outer contour of the winding shaft in the compensation area 17; 18; 19; opposite the outer contour of the between the two compensation areas 17; 18; 19; arranged cloth area 16.
    Figures 9 and 10 show in sketched form on a winding shaft patch compensation rings 20a; 20b, wherein the compensating ring 20a has an outer dimension that is constant over the width of the compensating region 21, and the compensating ring 20b has a shape of the compensating region 22 that transitions from outside to inside over free forming surfaces onto the outer contour of the tissue region 16.
    FIG. 5 shows another building opening shading device according to a further embodiment of the invention, in which the compensation areas of the winding shaft 53 can also be designed as shown in FIGS. 6 to 10 and 13. In this case, a fly screen mesh net 54 is wound onto a winding shaft mounted above a window F, which mesh screen is in turn guided over edge thickenings 56 in associated guide rails 52 and has a guide strip 55 on its underside.
    Modifications and modifications of the embodiments shown are possible without causing the scope of the invention.
