Description

The invention relates to an exchangeable material for a shading system and a shading system, in particular pleated system with such a replaceable substance having the features of the preamble of claim 1.

Such a shading system and such a replaceable material for a shading system are for example from the DE 20 2014 104 192 U1 refer to. In particular, the exchangeable fabric is designed as an approximately zigzag-folded fabric which extends in a longitudinal direction and in a transverse direction. By the zigzag folding horizontal Faltlamellen are formed, which are each connected to one another at a transverse folding edge. Through the individual folding blades aligned holes are introduced in the longitudinal direction through which in the mounted state, a longitudinally extending guide element is performed. This is usually a guide cord or a guide rod.

In pleated installations, such a folded fabric is held like an accordion between a lower and an upper profile rail. These rails are held along the guide elements within a frame, such as a window frame or door frame slidably. Due to the mobility of the profile rails on both sides, different areas can be covered in pleated installations.

In such pleated installations the threading of the guide elements through the individual aligned holes of the fabric is usually associated with some effort. Substitution of the substance is difficult in conventional pleated plants.

In order to facilitate such an exchange of the substance, according to a variant of the DE 20 2014 104 192 U1 starting from a respective hole laterally to a rear side extending slots so that a respective guide element laterally on the slots in and out of the holes and can be executed. The fabric can therefore be removed laterally, ie in the direction of a surface normal of the surface to be shaded and thereby easily replaced. In this case, use is made of the fact that the material has a certain elasticity and can therefore be spread apart, so that the slot can be widened for assembly or disassembly in order to be able to guide the guide element through the slot.

Through the slots, however, the overall stability of the shading system and the fabric is reduced, which has a disadvantage, especially for larger surfaces to be shaded.

Based on this, the present invention seeks to ensure a reliable function of a shading system with such a replaceable substance.

The object is achieved according to the invention by an exchangeable material for a shading system and by such a shading system with an exchangeable material with the features of claim 1. Based on the particular zigzag folded fabric, starting from the mutually aligned holes to a rear side Having extending slots, an additional securing element is arranged in the region of at least some of the holes, which secures the respective guide member against accidental lateral slipping out of the holes.

The reverse side is generally understood to mean the side of the material at which the slots run out freely. The opposite side is called the front side. Preferably, the rear side is oriented in the mounted state in the direction of the surface to be shaded (window), so the window side, so that the slots are not visible from the user from the inside. Basically, however, a reverse mounting is possible, so that therefore the slots on the opposite side of the window (room side) leak. In this case, then this side forms the back of the fabric. In the following, the rear side is understood as the window side and the front side is understood as the room side, without restricting generality.

The arrangement of such an additional securing element is based on the recognition that in a shading system according to the DE 20 2014 104 192 U1 in the case of larger surfaces to be shaded, there is the danger that the substance will slide off the guide elements on its own and is therefore no longer reliably guided. In order to avoid this accidental slipping out in the lateral direction of the guide elements from the holes, the securing element is now designed such that the force required to lead out the guide elements is increased over the slots or the lead-out is prevented. The required effort is dimensioned such that it is higher in all cases than the forces occurring during normal operation and normal handling of the shading system. The lateral direction is understood to be, in particular, the direction of a surface normal of the surface to be shaded (window surface), which thus extends transversely to the transverse direction and transversely to the longitudinal direction.

The advantage of the arrangement of such security elements is that conventional materials can continue to be used, even those which are very light and thus easily bendable and which would thus be susceptible to slipping sideways. Another advantage is also to be seen in the fact that the securing element needs to be arranged only at certain points and a few selected holes, so that the security elements so that the overall appearance is not or only slightly disturbing. Such a fuse element can also can also be retrofitted without problems, so that existing shading systems can be upgraded with such a replaceable material.

In a preferred embodiment, the securing element is optionally designed as a reinforcing element, as a spacer element or as a thickening element. In one embodiment, as a reinforcing element of this is locally attached to the fabric in the region of the hole and stiffened or reinforced this at least at the edge of the hole, so that bending of the slot difficult and is possible only with increased effort or even prevented. The basic idea of the reinforcing element is therefore to be seen in increasing the rigidity of the material locally in the area of the slot.

In the embodiment as a spacer element this is inserted in the region of the hole between the guide element and the fabric, so that a lateral displacement of the substance is prevented relative to the guide member to prevent accidental lateral slipping out of the holes. The spacer element is therefore inserted between the guide element and a material region oriented toward the front, in particular a folding edge, on which the individual folding blades are connected to one another.

By the spacer element is virtually formed a blocking element.

Finally, in the embodiment as a thickening element, this is designed such that it surrounds the guide element in the region of the hole, so that the guide element is thickened locally and to a limited extent and unintentional lateral slipping out of the respective hole is prevented. To be able to mount the thickening element, for example, also later, this is preferably fastened by a lateral approach to the guide element on this. There is therefore no threading of the thickening element required. Due to the thickening of the guide element in the region of the hole, in turn, the force required to bend the slot is increased, since the thickening of the slot requires more expansion.

Generally, the slot is formed with the smallest possible slot width, which is preferably also zero, so that the slot is formed only by an incision. In particular, the slot width is thinner than the width of the guide element. Conversely, the holes are usually thicker than the guide element, so have a larger diameter, so that the guide element is loosely guided in the holes.

According to a preferred embodiment, the securing element itself has a guide hole, through which the guide element is loosely guided in the mounted state. The guide hole is aligned in the assembled state preferably with the hole to be secured of the substance. By this configuration, the normal operation of the pleated plant, so the adjustment of the substance along the guide elements is not hindered. This embodiment is particularly true for the embodiments of the securing element as a stiffening element and / or thickening element.

With a view to the simplest possible assembly of the securing element, this is in particular in the variant as reinforcing element or thickening element on the one hand attachable by lateral introduction and configured such that it surrounds the guide element. For this purpose, the securing element in particular has a lateral insertion slot for the lateral insertion of the guide element. Conveniently, the insertion slot is brought into coincidence with the slot of the fabric.

In this case, the securing element is in particular an elastic element, so that it is thus elastically expandable in order to guide the guide element out through the insertion slots again if necessary. The slot width of the insertion slot is in particular smaller than the width of the guide element. Again, it may be provided that the slot width is also zero.

In an expedient development, the insertion slot is bounded by edge regions which, when viewed in the longitudinal direction, overlap or overlap one another, that is, when viewed in a longitudinal direction, one edge region covers the other edge region. Alternatively, the two edge areas abut each other directly. According to a third variant, the edge regions finally overlap in the lateral direction, so that the insertion slot forms a labyrinth-like or serrated profile. In particular, the embodiments with the overlapping edge regions thereby reliably secure the guide element against unintentional detachment.

In an expedient development, a notch is provided opposite the insertion slot on the securing element designed in particular as a reinforcing element. This facilitates the bending of the securing element and thus of the insertion slot in the case of a desired assembly / disassembly of the substance.

In particular, in the embodiment variant as a reinforcing element, the securing element is preferably bent towards the slotted rear side, in particular curved in the manner of a segment of a circle. This also supports a defined elastic bending of the reinforcing element, in particular in combination with the oppositely introduced notch.

Overall, the securing element is preferably formed as a flat thin element and in particular formed plate-shaped. It has a thickness, for example in the range of 0.5 to 2 mm. As a result, the setting of a desired elasticity and thus resistance to bending of the insertion slot in the desired manner is adjustable. Also, handling of the fuse element, for example, for attachment to the fabric or for subsequent insertion of an already mounted shading system allows.

The securing element is expediently formed from a transparent material, so that it does not interfere with the appearance of the substance or as little as possible. Preferably, the securing element is designed as a plastic element.

In particular, however, in the embodiment as a reinforcing element, the securing element may alternatively be formed as a textile reinforcing element. In principle, there is also the possibility that the substance is reinforced in the region of the hole in a suitable manner for the formation of the reinforcing element. For example, for this purpose, the fabric is processed by a textile processing method, such as embroidery, sewing, etc. or soaked with a thermosetting material, for example in the manner of an adhesive, which reinforces the fabric in the region of the hole after curing.

In a preferred embodiment, the securing element is fastened in particular in its embodiment as a reinforcing element directly on the fabric and glued in particular on this. The securing element is designed according to a first embodiment as a self-adhesive film. Alternatively, the securing element is secured to the fabric by means of an adhesive film which is applied over the securing element and the fabric. Finally, there is also the possibility of attaching the securing element to the fabric otherwise, for example by sewing etc.

In order to disturb as little as possible the optics of the shading system by the securing elements and, secondly, to unnecessarily increase the weight of the substance, the securing element in a preferred embodiment is in each case formed locally only for a single hole. A respective securing element is therefore assigned in each case only to a single hole. In particular, in the embodiment variant as a small plate, this is therefore attached around the respective hole.

In an alternative embodiment, the securing element extends in the transverse direction over a plurality of holes and in particular over the entire width of the substance. In this embodiment variant, the securing element is designed, for example, as a (transverse) rod or as a transverse plate. This variant is particularly advantageous in the design of the securing element as a spacer element. This then only needs loose between the guide elements and a folding edge of the fabric to be introduced. In particular, in this embodiment, only a loose insertion of the fuse element.

In all cases, however, it is expediently provided that at most some of the holes have a securing element assigned to them in the longitudinal direction of the material. Therefore, not all holes are deliberately provided with a securing element. Rather, have holes, which is associated with a securing element to longitudinally adjacent holes with securing element or to a marginal attachment of the substance to a rail preferably a distance of at least several 10 cm and in particular of at least 40 or 60 cm. This embodiment is based on the knowledge that even a few securing elements distributed in the longitudinal direction are sufficient to reliably prevent lateral slipping of the substance from the guide elements. The problem of slipping arises only with very long shading systems. For shading systems with a total length, for example, up to 1 m or 1.20 m, safety elements are not absolutely necessary if the choice of material is suitable. In shading systems with a total length of the surface to be shaded (window area) in the range, for example, from 100 to 150 cm, therefore, preferably only 1 to 2 securing elements are provided distributed in the longitudinal direction. And for shading systems with a length in the range of 150 to 200 cm, for example, only 2 to 3 security elements. Generally, this is at least one securing element - viewed in the longitudinal direction - spaced from the profile strips / a fabric edge mounted only in a central region of the fabric.

The securing element is expediently provided, in particular in its configuration as a spacer element, with a contact edge, with which it lies against a folding edge of the material in the mounted position. The spacer element therefore supports itself with the contact edge on the folded edge. The width of the securing element is therefore adapted at least in the region of the hole to the distance between the hole and the folded edge of the fabric and preferably corresponds at least approximately to this distance.

In an expedient embodiment, the securing element, in particular in its embodiment as a spacer element on its side facing the guide element on at least one retaining notch, in which rests the guide element in the assembled state. As a result, the spacer element is secured against lateral slipping in the transverse direction, especially in the case of the embodiment in which it is clamped between the guide element and the folded edge of the fabric. Usually, a shading system has a plurality of guide elements distributed in the transverse direction. Usually, two or three guide elements are arranged distributed over the width. Accordingly, the securing element preferably has the same number of retaining notches, wherein the individual retaining notches have the same spacing grid as the guide elements over the length of the securing element.

• Gemäß einer ersten Ausführungsvariante ist dieses als ein auf den Stoff insbesondere durch Kleben befestigtes Plättchen mit einem Einführschlitz ausgebildet, wobei das Plättchen lediglich einem einzigen Loch zugeordnet ist.
• Alternativ ist das Verstärkungselement als ein das Loch umgebender Versteifungsring mit einem Einführschlitz ausgebildet. Der Versteifungsring ist dabei am Stoff befestigt und insbesondere als eine geschlitzte Öse ausgebildet. Durch den Einführschlitz lässt sich diese geschlitzte Öse einfach in seitlicher Richtung anbringen.
• In einer weiteren alternativen Ausgestaltung ist das Verstärkungselement nach Art eines Schrankenelements ausgebildet, welches in Querrichtung neben dem Schlitz am Stoff befestigt ist und sich lose über den Schlitz in Querrichtung erstreckt. Das Schrankenelement ist dabei flexibel, so dass es entweder seitlich bzw. nach oben weggebogen werden kann.

In the embodiment of the securing element as a reinforcing element this is formed in preferred alternatives:

• According to a first embodiment, this is designed as a fixed to the fabric in particular by gluing platelets with an insertion slot, wherein the platelet is associated with only a single hole.
• Alternatively, the reinforcing element is formed as a surrounding the hole stiffening ring with an insertion slot. The stiffening ring is attached to the fabric and in particular designed as a slotted eyelet. Through the insertion slot, this slotted eyelet can easily attach in the lateral direction.
• In a further alternative embodiment, the reinforcing element is designed in the manner of a barrier element, which is fastened in the transverse direction next to the slot on the fabric and extends loosely across the slot in the transverse direction. The barrier element is flexible, so that it can be bent away either laterally or upwards.

• Gemäß einer ersten Variante ist das Distanzelement als ein Plättchen ausgebildet, welches lose zwischen dem Führungselement und einer Faltkante eingeklemmt und lediglich einem Loch zugeordnet ist.
• Gemäß einer zweiten Alternative ist das Distanzelement ein sich über mehrere Löcher in Querrichtung erstreckender und lose zwischen dem Führungselement und einer Faltkante angeordneter, insbesondere eingeschobener Stab oder Querplatte ausgebildet.
• Gemäß einer dritten bevorzugten Variante ist das Distanzelement als eine Wendel ausgebildet, welche um das Führungselement angebracht ist, wobei die Wendel insbesondere lediglich für ein Loch ausgebildet ist und die Wendel weiterhin vorzugsweise einen verdickten Mittenbereich aufweist. Die Wendel wirkt dabei insoweit als Distanzelement, als dass bei einem seitlichen Verrutschen des Stoffes relativ zum Führungselement der Stoff an seiner Vorderseite an der Wendel zum Anliegen kommt, bevor das Führungselement aus dem Schlitz herausrutschen kann.

In its embodiment as a spacer element, the securing element is furthermore preferably designed optionally in different preferred variants:

• According to a first variant, the spacer element is designed as a small plate, which is clamped loosely between the guide element and a folding edge and assigned only to a hole.
• According to a second alternative, the spacer element is a rod or transverse plate which extends over a plurality of holes in the transverse direction and is arranged loosely between the guide element and a folded edge, in particular inserted.
• According to a third preferred variant, the spacer element is formed as a helix, which is mounted around the guide element, wherein the helix is in particular formed only for a hole and the helix further preferably has a thickened central region. The helix acts insofar as a spacer element, as that when a lateral slippage of the fabric relative to the guide element, the fabric comes to rest on the front of the helix before the guide member can slip out of the slot.

Finally, the securing element is designed in its embodiment as a thickening element in a preferred embodiment as a rigid sleeve with lateral insertion slot, which is oriented in particular obliquely with respect to the longitudinal direction. Unlike the slotted eyelet, therefore, the sleeve also extends in the longitudinal direction over the hole edges of the holes and has, for example, a length of 0.5 to 1 cm. The sleeve has in particular a collar, with which it comes to rest on a hole edge of the respective hole. Due to the oblique orientation of the insertion slot slipping out of the guide element from the sleeve is reliably avoided.

As an alternative to such an inherently rigid sleeve, the guide element is banded, for example, in regions, so that it is thereby thickened.

In a preferred embodiment, it is further provided that the securing element bears frictionally on the guide element, such that undesired slippage of the material relative to the guide element is avoided. Under frictional fitting is understood here that a certain frictional force is exerted, so that in particular for larger shading systems, the substance does not slip down by its own weight along the guide elements, so that the desired lamellar and folding optics is maintained. At the same time, however, an adjusting movement must continue to be possible to ensure the normal operation of the shading system, in which yes a relative displacement between hole and guide element must be ensured. Also for this purpose is in the longitudinal direction, a single or only a few security elements are sufficient.

The object is further achieved by a securing element for such a previously described exchangeable material, wherein the securing element is formed against unintentional slipping out of the guide element from the holes of the material. The securing element is designed in particular as a retrofit element for existing shading systems and also suitable for retrofitting. The advantages and preferred embodiments cited with regard to the shading system and the exchangeable material are to be transferred analogously to the securing element as such.

In the figures, like-acting parts are provided with the same reference numerals.

In Fig. 1 is designed as a pleated blind shading system 2 partial. Such a shading system 2 usually has two profiled rails 4, of which in Fig. 1 only the lower rail 4 is shown. Between the two rails a particular folded fabric 6 is arranged. The fabric 6 is folded approximately accordion-like, so that individual in a transverse direction 8 extending fabric slats 10 are formed, which are each connected alternately via a folding edge 12 with each other. The lowermost and the uppermost fabric lamella 10 is in each case attached to the respective profile rail 4. For example, this is done in the manner of a hook and loop fastener or with the help of a laterally introduced so-called piping.

The profile rails 4 together with the substance 6 fastened between them can be displaced in the mounted end position along usually at least two guide elements 16 in a longitudinal direction 14 along the surface to be shaded. In the exemplary embodiment, the guide element 16 is designed as a guide cord, also called a tension cord. This is in each case attached to a lower edge and an upper edge of the surface to be shaded, for example a glazing bead, by means of a so-called cord tensioner 18.

The guide member 16 is passed through the fabric 6, through the individual fabric slats 10, through holes 20 in the longitudinal direction 14 loosely. The holes 20 are aligned in the longitudinal direction 14 to each other.

The fabric 6 is formed as an exchangeable fabric. It can be solved in the lateral direction 22, ie perpendicular to the transverse direction and perpendicular to the longitudinal direction 14 and thus in the direction of a surface normal of the surface to be shaded of the guide elements 16. For this purpose, a plurality of slots 24 are introduced into the fabric 6, each starting from the individual holes 20th extend in the lateral direction 22 to a designated here as the back side 26 side of the fabric 6. The opposite side is referred to as the front side 28. The rear side 26 is in particular the window side and the front side 28 is the room side. The replacement of the substance 6 takes place in this case such that the slots 24 are bent due to the elasticity of the substance 6, so that the guide element 16 can be guided laterally outwards through the slots 24.

For larger shading systems, for example, with a length in the longitudinal direction 14 of more than 120 cm, the problem may arise that the guide elements 16, for example, in an air movement, etc. automatically slip out of the slots 24.

In order to prevent this, now a certain number of securing elements are arranged in the shading system 2, which prevent such unwanted lateral slipping out.

The securing elements described below can be fundamentally differentiated into three basic types, namely reinforcing elements 30, spacing elements 32 and thickening elements 34. The basic function of these securing elements 30, 32, 34 is that they at least have the required force for lateral removal of the substance from the guide elements 16 increase, so that the forces occurring during normal operation are no longer sufficient for an unwanted lateral sliding out. Alternatively, the design of the respective securing element, in particular in the embodiment as a spacer element 32, a lateral slipping completely prevented and it is possible only after removal of the spacer element 32. The securing element acts here as a blocking element which blocks the slot 24 and releases the slot 24 only after removal or at least displacement / rotation of the securing element.

Viewed in the longitudinal direction 14, securing elements 30, 32, 34 are attached to only a few holes 20. A distance a between a fuse element 30,32,34 to a longitudinal direction 14 adjacent securing element 30,32,34 or to a rail 4 is preferably more than 40 cm and in particular more than 60 cm and is for example 80 cm. The distance a is measured in this case at the maximum provided extract of the substance 6 in the longitudinal direction 14th

Different embodiments of the formed as reinforcing elements 30 fuse elements are described below with reference to the Fig. 1 to 7 described. Different embodiments of the spacer element 32 are based on the Fig. 8 to 10 described and a variant of the thickening element 34 is based on the Fig. 11 described.

That in the Fig. 1 to 4 shown reinforcing member 30 is formed as a locally a single hole 20 associated thin plate 30a. This is attached to the fabric slat 10. For this purpose, the plate 30a is formed for example self-adhesive and glued accordingly. The plate 30 a has a guide hole 36 which is congruent with the hole 20. Starting from the guide hole 36, an insertion slot 38 extends in the lateral direction 22. Also, the insertion slot 38 is preferably congruent with the slot 24. In the exemplary embodiment, the plate 30a is preferably formed in the manner of a circle segment. It is preferably formed curved towards the back 26 and has towards the front side 28, ie toward a folded edge 12 out, a straight-line edge. A notch 40 is inserted in this edge, preferably opposite the insertion slot 38. The notch 40 allows a defined bending of the plate 30a, so that the insertion slot 38 is bent to the guide member 16 through the insertion slot 38 at a desired assembly / disassembly to be able to lead through.

The insertion slot 38 has - regardless of the specific configuration of the securing element - while generally a slot width b1, which is smaller than a width b2 of the guide member 16. In the embodiment of Fig. 1 to 3 In this case, the plate 30a has a jagged insertion slot 38, wherein the individual edge regions 42 which define the slot, directly abut one another, so that in this case the slot width b1 is zero. Due to the jagged course, individual sections of the edge regions 42, viewed in the lateral direction 22, are arranged overlapping one another. The plate 30a preferably has a thickness d in the range of 0.5 to 2 mm. In particular, it is designed as a transparent plastic plate.

In the Fig. 4A - 4C Variants of the plate 30a are shown, wherein in the Figs. 4B and 4C different variants of overlapping edge regions 42 are shown. According to the Fig. 4B overlap the adjacent edge portions 42 viewed in the longitudinal direction 14. This is at least partially also in Fig. 4C the case, in which case the individual edges of the edge regions 42 are not parallel as in the embodiment according to Fig. 4B but obliquely oriented to each other, so that the back 26 toward a V-shaped notch is formed.

In the Fig. 5A, 5B For example, the reinforcing element 30 is formed by two barrier elements 30B. These are each formed as extending in the transverse direction 8, for example, rod-shaped elements which are attached to a foot portion 43 adjacent to the slot 24 on the fabric 6 and extend with a free end over the slot 24 in the manner of a barrier. The fastening of the foot region 43 takes place, for example, by gluing, wherein the foot region 43 is in particular self-adhesive and, for example, formed with an adhesive film. The free ends can be bent away for assembly / disassembly of the fabric 6, so that the slot 24 is released. For this purpose, the individual barrier elements are suitably themselves elastically or at least elastically or hingedly attached to the fabric.

In the embodiment according to the Fig. 6A, 6B For example, the reinforcing member 30 is formed as a slotted eyelet 30c surrounding a hole edge of a respective hole 20. The slotted eyelet 30c in turn has an insertion slot 38 so that it can also be attached later. The slotted eyelet 30c may be loosely attached to the hole 30 or be frictionally secured thereto, for example by riveting. In a loose Arrangement is possible to rotate the eyelet 30c relative to, so that - unlike in Fig. 6B shown - the insertion slot 38 is not aligned with the slot 24, but is offset laterally. In the Fig. 6A these two embodiments are shown by way of example, wherein in the upper fabric lamella 10 a twisted by 90 ° eyelet 30c is shown. The eyelet 30c is a total of an annular element, as in particular in the Figs. 7A to 7C is shown. This has, in addition to the insertion slot 38 and the guide hole 36, a circumferential groove 44 into which the hole edge circumferentially engages.

That in the 8A, 8B Distance element 32 shown is also formed as a plate 32 a, which is assigned only to a single hole 20. It also has an approximately circular segment-like shape and also has a guide hole 36 and an insertion slot 38, as well as the plate 30 a, which is designed as a reinforcing element 30. The formed as a spacer element plate 32a has towards the back 26 toward a contact edge 46, with which it rests against a respective folding edge 12 in the assembled state. The plate 32a is, for example, a loose and is therefore between the guide element 16 and folded edge 12 quasi clamped. Alternatively, the plate 32a may also be attached to the fabric 6. By the spacer element 32 is generally prevented that the material 6 can move from the back 26 forth in the lateral direction 22 in the direction of the guide member 16. As a result, slipping out of the guide member 16 is effectively avoided by the slot 24.

In the embodiment according to the Figs. 9A, 9B the spacer element 32 is formed as a transverse bar 32b, which is inserted in the transverse direction 8 loosely between the guide member 16 and the folding edge 12. The transverse rod 32b has one and preferably a plurality of retaining notches 48, in which the guide element 16 rests in the mounted state.
