Definitions

  • the invention relates to an awning fabric according to the preamble of claim 1 and a shading device comprising the awning fabric according to claim 11.
  • Shading devices or sun protection systems with a fabric web that can be extended or unwound from a rotatably mounted winding shaft are known to those skilled in the art as "fabric or vertical awnings”.
  • a "ZIP solution” is known in which a two-part guide rail comprising a receiving profile and a carrier profile is used.
  • the support profile is attached to a wall reveal with screws.
  • a guide profile for guiding the awning fabric is then inserted into the carrier profile and the receiving profile is connected to the carrier profile so that the carrier profile is held in the guide rail.
  • an increased susceptibility to breakage has been shown, in particular under heavy loads, such as gusts of wind.
  • their manufacture and / or assembly is often very complex.
  • the awning fabric comprises at least one stretch strip which extends over the entire length of the awning fabric and is integrated into the awning fabric or attached to it along its length.
  • the stretch marks each include a transversely elastic middle area, which is flanked on both sides by non-transversely elastic areas.
  • the non-transversely elastic areas are used to attach the expansion strip to the fabric web or to attach welt elements along the length of the expansion strip.
  • the middle, transversely elastic area of the expansion strip takes on the function of the elastic expansion elements described above and enables a fabric tension to be built up in the transverse direction and, for example, to absorb wind pressure in a springy manner.
  • the technical problem on which the invention is based is to provide an awning fabric for a shading device, in particular for a fabric or vertical awning, which is also able to absorb and cushion larger load peaks, for example due to the action of wind, and a simplified, inexpensive structure as well as a enables long-lasting and low-wear operation of the shading device.
  • the awning fabric according to the invention comprises a fabric web having two side edges in a longitudinal direction, two longitudinal strips along the side edges in a respective fabric edge area directly adjoining the side edges, as well as guide elements which run at a distance from and at least approximately parallel to the side edges of the fabric web and are provided for guiding the awning fabric on both sides in guide rails of a shading device.
  • the term “longitudinal direction” means the direction of extension (or, in general, the direction of movement) of the cloth web, i.e. at right angles to the winding shaft.
  • a “longitudinal strip” denotes a material strip or a band which extends in said longitudinal direction of the cloth web.
  • the guide elements are attached to the longitudinal strips along a respective free strip edge.
  • the awning fabric thus comprises, on the one hand, the fabric web and, on the other hand, also the two longitudinal strips connected to the fabric web along the side edges in the associated fabric edge area, including the guide elements attached to the longitudinal strips in the longitudinal direction along the free strip edges.
  • said longitudinal strips are each transversely elastic over their entire width, at least when they are not mounted on the awning fabric.
  • the "width” refers to the dimension of the longitudinal strip in the transverse direction, that is, at right angles to the longitudinal direction.
  • elasticity refers to the ability of a material, especially a textile material, to deform elastically under an applied force and to return to its original shape after releasing - i.e. without permanent plastic deformation.
  • transversely elastic in relation to the longitudinal stripe thus means in the context of the present invention that the longitudinal stripe is reversible in the transverse direction, starting from a relaxed (rest) state Force can be brought into a stretched state elastically.
  • the awning fabric Due to the transverse elasticity of the longitudinal strips arranged on both sides along the fabric web, a resilient tensioning movement of the awning fabric in the transverse direction is brought about according to the invention.
  • the awning fabric In the assembled state, the awning fabric can absorb force peaks between lateral guide rails of a shading device when there is a strong wind.
  • the awning fabric according to the invention offers the advantage that, thanks to the transversely elastic longitudinal strips, the forces acting on the fabric can be absorbed and stabilized by the fabric itself, without the need for additional elastic elements.
  • the rubber or foam elements (such as in the CH-B1-702 041 ) can be waived. This allows a significantly slimmer design of the guide rails, which is advantageous not only from an aesthetic point of view, but in particular because of lower material, manufacturing and assembly costs.
  • the longitudinal strips are each connected in an overlapping manner in a strip edge area with the associated cloth edge area, preferably glued.
  • a heat-activatable adhesive is preferably used, that is to say an adhesive whose adhesive properties are activated by the supply of heat.
  • the longitudinal strips can be quickly and securely connected to the fabric without affecting the aesthetics or functionality of the awning fabric affect.
  • the strip and the associated cloth edge area can also be connected by means of a textile double seam. It should be mentioned here that, due to the essentially non-elastic material of the cloth web, the transverse elasticity of the longitudinal strip can be reduced in the overlapping area.
  • the longitudinal strips are each preferably formed from longitudinal and transverse threads with different elasticity.
  • warp and “weft” are also used instead of “longitudinal and transverse threads”. Since the longitudinal strip is intended to be transversely elastic according to the invention, the transverse threads generally have a higher elasticity than the longitudinal threads.
  • the transverse threads (or the “weft”) preferably have an elasticity of 100: 245 to 100: 275, in particular of at least approximately 100: 260.
  • the first number defines the length of the threads in the relaxed (rest) state and the second number indicates the length to which the threads can be elastically stretched maximally.
  • the transverse threads can therefore particularly preferably be stretched 2.6 times - e.g. from a length of 100 mm in the relaxed state to 260 mm in the maximally stretched state.
  • the elasticity along and across the thread can be individually adjusted, for example, by combining different materials for the wrapping and the core of the thread.
  • transverse threads with a core made of elastane and a polyamide wrap are used.
  • each longitudinal strip has an elasticity of 100: 129 to 100: 150, preferably at least approximately 100: 140, in the transverse direction.
  • the guide elements are in the form of a piping and, particularly preferably, are designed as a continuous, flexible piping on each longitudinal strip along the associated free strip edge.
  • the guide elements can therefore be designed, for example, as a series of welts, as in the case of a zipper half, or as an uninterrupted hem.
  • the welt hem is also preferably formed integrally with the respective longitudinal strip.
  • integrally formed is understood to mean a material-fitting, continuous transition of the longitudinal strip into the piping hem. This ensures a particularly stable connection between the longitudinal strips and the piping.
  • the piping can be wrapped with longitudinal and / or transverse threads of the longitudinal strip. In this way, the horizontal strips can be connected to the piping hem in the course of their production.
  • the structure or the weaving and winding parameters for the production of a transversely elastic band are in connection with Figure 6 described in detail.
  • the welt hem preferably also has a plastic core, preferably circular in cross section, which has a Has sheath.
  • the plastic core and / or the sheath consists or preferably consist of polyester.
  • the clear width of each longitudinal strip in the relaxed state measured between the side edge of the cloth web and the free strip edge of the assigned longitudinal strip (and thus the guide elements) - 5 to 15, preferably 8 to 12, particularly preferably at least approximately 10 mm.
  • the clear width thus defines the part of the longitudinal strip which performs the damping function of the awning fabric. If the longitudinal strip is connected to the fabric web in an overlapping manner in a strip edge area, the longitudinal strip also has transversely elastic properties on its own in the overlapping area, but due to the connection with the fabric web, which has essentially no or only very little elasticity, it cannot have any in the overlapping area or only exercise a reduced damping function.
  • the thickness of the guide elements - measured at right angles to the plane of the cloth - is preferably 2 to 5 mm, particularly preferably at least approximately 3 mm.
  • the thickness of the guide elements is preferably matched to the clear width of the guide groove of a guide rail in a shading device according to the invention described below, so that the guide elements cannot pass through the guide groove.
  • the present invention also relates to a shading device comprising two guide rails which are arranged at a distance from one another and generally run parallel to one another a respective guide chamber as well as a winding shaft rotatably mounted above the guide rails with an awning fabric according to the invention which is fastened to the winding shaft and can be wound on or unwound from it, as described above.
  • each guide chamber is delimited on the fabric side by a front wall with a guide groove that is continuous and undercut in the longitudinal direction.
  • the awning fabric is guided and held in the guide rails on both sides by means of guide elements held in the guide chambers.
  • the longitudinal strips reach through the respective guide groove.
  • the distance measured in the transverse direction from guide element to guide element is greater than the distance from guide chamber to guide chamber.
  • Sliding guide elements can be achieved, which are positioned on both sides of the guide groove and prevent the awning fabric from rubbing against the edges of the guide groove.
  • Corresponding sliding guide elements can be held in the guide rails, for example on the front wall, for example in undercut longitudinal grooves formed on both sides of the guide groove.
  • each of the guide rails furthermore has a fastening chamber which is preferably at least partially separated from the guide chamber and delimited by a rear wall having a through hole.
  • Said through-hole is provided in particular for the implementation of a fastening means, in particular a shaft of a screw, for fastening the guide rail to a wall reveal.
  • the guide rail is particularly preferably fastened by means of screws which are screwed into the wall through the through holes in the rear wall.
  • each guide rail preferably has an inlet funnel at an end facing the winding shaft, which makes it easier for the holding elements to run into the respective guide groove.
  • Fig. 1 shows part of a fabric or vertical awning serving as a shading device, which comprises, in a known manner, a box 10, usually arranged on the lintel side of a building opening, and two guide rails 12 that are at least approximately perpendicular to the box 10 and are arranged parallel to one another. In the figures, only one of the guide rails 12 is shown in each case.
  • the guide rails 12 are designed in one piece and in the form of a profile and each have a guide groove 13 extending in the longitudinal direction L.

  • a rotatably mounted winding shaft 14 which can be driven in the winding and unwinding direction and onto which an awning fabric 18 comprising a fabric web 16 can be wound or from which said awning fabric 18 can be unwound.
  • the awning fabric 18 is fastened with its upper end to the winding shaft 14 and at its extension-side or lower end 20 a drop rod 22 extending in the transverse direction Q and thus arranged parallel to the winding shaft 14 is attached, which can be provided with weights and opposite the winding shaft 14 is movably guided in a longitudinal direction L defined by the cloth web 16 and the guide rails 12 in the guide rails 12.
  • the winding shaft 14 can have an electrical drive (not shown) in a known manner or, if necessary, can also be driven manually.
  • the box 10 has two side walls 23 and a cover 25 formed in one piece with a panel 24.
  • the box 10 also has an extension opening 26 which is dimensioned such that it can be passed by the drop bar 22. This allows the drop rod 22 to be at least partially retracted into the box 10.
  • the clear width of the extension opening 26 accordingly corresponds at least to that (width measured at right angles to the plane of the cloth) of the drop bar 22.
  • Both the awning fabric 18 and the drop rod 22 are guided on both sides in the lateral guide rails 12 of the shading device.
  • each of the guide rails 12 has a respective inlet funnel 29 at its upper end 28 facing the winding shaft 14, which, starting from the upper end 28, widens in a funnel shape and protrudes into the box 10.
  • Each inlet funnel 29 has an inlet welt groove 30 which merges seamlessly into the guide groove 13 of the respective guide rail 12 on the underside. This ensures that the awning fabric 18 runs smoothly into the guide grooves 13 of the guide rails 12.
  • the inlet funnels 29 are usually connected to the guide rails 12 by clipping.
  • the inlet funnel 29 rests with a lower edge 31 on an end face 32 at the upper end 28 of the guide rail 12 and has two spring tongues 33 with a respective latching cam 34.
  • the spring tongues 33 engage with their locking cams 34 in respective locking holes 35 in the guide rail 12 and connect the inlet funnel 29 to the respective guide rail 12.
  • the drop bar 22 has, at its ends facing the guide rails 12, two projections 44 each engaging in the guide rails 12.
  • the drop bar 22 is securely held in the guide rails 12 on both sides. Without wind load, the projections 44 are guided in the guide rails 13 without contact.
  • the two ends with the projections 44 are preferably made of plastic, preferably polyamide, such as PA 6.6, or a rubber material, so that when the protective device is deflected perpendicular to the plane of the cloth, for example under wind load, rattling noises can be largely avoided by striking the drop bar on the guide rail.
  • the awning fabric 18 has the fabric sheet 16 with two side edges 36 extending in the longitudinal direction L and further comprises a number of guide elements 37 running at a distance from the side edges 36 Guide rails 12 of the shading device.

  • the material of the cloth web 16 and that of the longitudinal strips 40 differ in particular with regard to their extensibility in the transverse direction Q.
