Description

BACKGROUND OF THE INVENTION

FIELD OF THE INVENTION

The The present invention relates to a roller blind arrangement according to the Preamble of claim 1.

STATE OF THE ART

Out The prior art are blind systems for closing known from window openings in motor vehicles. Especially There are sun protection systems for skylights or sunroofs, the are realized by appropriate Rolloanordnungen.

at the increasingly large roof openings, so-called panorama roofs, high demands are placed on the roller blind systems provided because large areas covered by the roller blinds Need to become. This causes the roller blinds in their dimensions, what the longitudinal extension and the As far as the broad dimension is concerned, we can regarding the guide rails as well as the stability of the roller blind in itself cause great demands.

at corresponding large roof systems become the roller blind systems for shading roof openings or panorama roofs designed so that the fabric or the rollable element guided in laterally arranged guide rails is and in the width direction, ie perpendicular to the guide rails, is under tension, to a bulging of the substance or Roll-up element to avoid or at least reduce.

Farther The guide rails are usually known in the art made of extruded profiles to the required lengths to be able to provide. The extrusion profiles are correspondingly cut to the desired length, although sharp-edged ends are created for the roller blind The problem is that when sliding in the guide rails Damage to the blinds on the sharp edges of the Ends of the guide rail can occur. Corresponding the guide rails are machined at their ends, to attach curves, bevels or the like, the easy and safe insertion and sliding of the Fabric or roll-up element of the roller blind in the guide rails enable.

These Machining the guide rails is very complex and therefore expensive.

DISCLOSURE OF THE INVENTION

OBJECT OF THE INVENTION

It is therefore an object of the present invention, a roller blind to provide that avoids the problems of the prior art and an easy to produce and easy to use roller blind represents. In addition, the roller blind is a comfortable, especially quiet and easy common, as well as safe guidance of the blinds in the guide rails, in particular in large-scale blind arrangements, enable.

TECHNICAL SOLUTION

These Task is solved with a roller blind arrangement with the features of claim 1. Advantageous embodiments are the subject of dependent claims.

The The above object is achieved in that at least a, preferably a plurality, separate from the guide rail Components are provided which serve as guide elements provided in the region of the insertion openings of the guide rails are to ensure a safe and comfortable introduction of the rollable Allow elements in the guide rails. By reducing the level of integration of the components, ie separation the function of the guide rail and the function of the guide element for Inserting the rollable element into the guide rail in two separate components, surprisingly, despite the additional components a simplification of the production with simultaneous improvement the properties are achieved. The properties can by forming the guide elements as separate Components are improved to a better and more effective Introduction of the substance or roll-up element in the Guide rails is possible because of separate Components increase the constructional degrees of freedom are.

simultaneously can continue to guide rails made of extrusion profiles can be used by simply cutting or separating the extrusion profiles in the desired lengths be made without any further post-processing of the ends can. This makes it possible, especially for Large roof systems, such as panoramic roof windows, in a simpler way Way corresponding guide rails for a Rolloanordnung provide, without complex procedures several guide rails to a guide rail having to assemble with appropriate length or a complicated post-processing of the insertion to make the guide rails.

Due to the possibility of appropriate extru To use sion profiles, is also given the opportunity to use or use a combined guide rail, which not only assumes the leadership function for the rollable element of the blind assembly, but also other management tasks, such as the leadership of corresponding components of a closure element, such as a Sliding roof or the like.

In order to It is also possible to both guide rails out Plastic as well as metal and in particular to use aluminum.

For the guide rails and in particular combined guide rails with different leadership tasks can profiles be used with a variety of forms, in particular forms, the one part with L-shaped cross-section or a tubular Have cross-section with longitudinal slot, for the inclusion of corresponding holding parts of the roll-up element and holding the holding parts of the rollable element under tension suitable is.

Around tensioning the rollable element accordingly, can be provided on the sides corresponding holding parts be that interact with the guide rails so that transversely to the longitudinal extent of the guide rails a Tensile stress is exerted on the rollable element can. The holding parts can be in the form of a welt, a Bead, a thickening or a corresponding roll-up profile be educated. The holding parts can be made in one piece formed with the flat main part of the rollable element or with this by suitable joining techniques, such as Example welding, riveting or the like connected be. The rollable element can be a flat main part made of plastic or textile, in particular fabric, is formed.

The Rollable element may be smaller in size than the Distance of the guide rails. That's how it has to be Roll-up element automatically when inserted into the guide rails stretched and stretched with it.

The Guide element can have at least one sliding surface and / or have a roller device on which the rollable Element and in particular the part of the flat main part, which is arranged in the vicinity of the holding parts, movable is.

The Sliding surface (s) and / or the envelope (s) of the Roller device can be designed so that the wedge-shaped and / or rounded to the insertion opening of the guide rails to run, so the rollable element gently and smoothly into the guide rail introduce. Due to the separately provided guide element In this case it is possible in particular, larger Tolerances for the arrangement of the guide rail and / or provide the guide element, so that also by the cost of producing the blind assembly small can be held.

Especially can by providing multiple sliding surfaces or envelope or arrangement of the corresponding guide elements an expansion of the roll-up element on the inside width of the opposite Guides (span) done and at the same time Rollable element on the management level of the guide rails to be brought. Of course, however, you can also only individual functions, thus either the widening of the Stoffes or the arrangement on a certain level separated from each other be realized. In addition, it is also possible that one of the functions is not realized, for example the winding roll on which the rollable element is wound, arranged in a plane with respect to the guide rails, that do not require level matching.

at the execution of the guide element by a Roller device can one or more, in particular provided behind one another, rollers or wheels be. With several roles or wheels can also with a Roller device a gentle and smooth adjustment of the rollable Elements on the guide area of the guide rails respectively.

EMBODIMENTS

The 1 shows in a cross-sectional view of a roller blind assembly, as can be found in particular for a window opening on a roof of a motor vehicle use. In the roller blind arrangement are two mutually parallel, oppositely arranged guide rails 1 and 2 provided, the holding parts 3 and 4 accommodate a rollable element, which between the holding parts 3 and 4 a flat major part 5 made of a flexible plastic or a textile.

The rollable element is wound on a winding roll (not shown) at one of the ends of the guide rails 1 and 2 is provided. By unwinding the roll-up element, where the holding parts 3 and 4 in the guide rails 1 and 2 can slide, by means of the flat body 5 the window opening can be closed and reopened by winding the roll-up element onto the winding roll.

Like from the 1 it can be seen, are the holding parts 3 and 4 the roll-up element on opposite legs of the L-shaped guide rails 1 and 2 so that according to the double arrow the flat main part 5 under tension. This ensures that the flat main part is taut and does not sag.

In addition to the cross-sectionally L-shaped design of the guide rails 1 and 2 as they are in 1 is shown, is also a tubular formation of the guide rails 1 and 2 possible as they are in 2 is shown. In the embodiment of the 2 are the tube-like guide rails 1 and 2 formed with a rectangular cross-section. However, other cross-sectional shapes are conceivable, such as squares, circular shapes or the like.

The tubular guide rails 1 and 2 the embodiment of the 2 have at their longitudinal sides in the longitudinal direction (axially) extending slots 6 respectively. 7 on that make it possible for the flat major part 5 to the holding parts 3 and 4 that are inside the guide rails 1 and 2 can be passed through. Accordingly, a part of the main part slides 5 in the slot 6 . 7 , Also in the embodiment of the 2 is the flat main body according to the double arrow shown under tension, so that the holding parts 3 and 4 on the insides of the guide rails 1 and 2 issue.

Like in the 2 through the main processes 19 indicated, the guide rails 1 and 2 Integrate further rail or leadership functions. For example, the guide rails 1 and 2 at the same time serve as guide rails for the components of a window closure in the form of a glass plate or the like.

The holding parts 3 and 4 are shown in the embodiment shown as rod elements with a rectangular cross-section. However, the holding parts can be realized by any suitable form, in particular flexible profiles, which are connected to the flat main part 5 welded, riveted or connected in any other suitable manner with this. Also a one-piece design of the holding parts 3 and 4 with the flat main part 5 is conceivable.

In particular, the holding parts 3 and 4 as well as the rails 1 and 2 that in the 1 to 2 are shown schematically, according to the embodiments of DE 10 2005 024 657 A1 be formed, which are hereby incorporated by reference fully in the present application. Above all, the holding parts can be stitched metal strips which are inserted into folded loops of the fabric or surface main part of the roll-up element or are accommodated in the latter. Such metal parts can be performed in variously shaped rails with slots which are arranged laterally, above or below, with additional moldings can be provided with.

The 3 to 5 show various embodiments of the blind assembly using the guide rails of the embodiment of 2 , Shown is the guide rail 1 with the longitudinal slot 6 from the side of the rollable element, which is not shown.

In the 3 to 5 it can be seen that at one end of the guide rail 1 , which represents the insertion opening for the rollable element (in the 3 to 5 the left end of the guide rail 1 ) a guide element 8th . 9 respectively. 11 is provided for the rollable element.

In the embodiment of the 3 is the guide element 8th formed as a wedge-shaped ramp, which has a sliding surface 13 for the rollable element. About the sliding surface 13 slides the holding element 3 adjacent part of the flat main part 5 , causing damage to the flat main body 5 is avoided by the edge at the insertion opening.

The holding part 3 will, as later in detail in 6 is shown by an in 3 not shown side surface 25 of the guide element 8th guided, in particular, the side surface obliquely to the longitudinal axis of the guide rail 1 can run so that through the guide element 8th , which in each case on the two guide rails 1 and 2 is provided, an expansion of the rollable element 5 takes place and thus the tension on the flat main part 5 is applied.

Instead of the guide element 8th in the form of a wedge-shaped element is in the embodiment of the 4 a roller assembly 9 consisting of three successively arranged rollers provided, wherein the envelope 10 the roles also obliquely to the plane of the flat main part 5 is arranged to the flat main part 5 to the plane of the slot 6 bring to.

In 5 is another variant of a guide element in the form of a pitch circle 11 with a rounded sliding surface 12 intended.

Also the guide elements 9 and 11 may be arranged so that, when guiding the rollable element over the corresponding guide elements 9 and 11 to a widening of the flat main part 5 comes.

6 shows a plan view of the embodiment of the 3 to the widening of the roller blind 5 or of the surface main part 5 to clarify the rollable element. Like in the 6 You can see the guide rails 1 and 2 mirror-symmetrical to the central axis between the guide rails 1 and 2 the two guide elements 8a and 8b assigned to the corresponding sliding surfaces 13a and 13b exhibit. The sliding surfaces 13a and 13b are on their inside, so the area associated with the main body side, with the side over the sliding surface 13a respectively. 13b protruding side walls 25a and 25b with a respective lateral stop for the holding parts 3 and 4 provided the roll-up element.

The side walls 25a and 25b are arranged at an angle obliquely to each other, so that they in the direction of movement of the rollable element of the winding roll 15 in the direction of the guide rails 1 and 2 diverge, so zoom in their distance. This will cause the retaining parts 3 and 4 of the roll-up element attached to the side walls 25a and 25b strike, be pushed apart, leaving the flat main body 5 of the rollable element is put under tension and stretched. Due to this tensile stress, the rollable, flat main body 5 in the unrolled state between the guide rails 1 and 2 a certain stability, which reduces the sagging of the flat body.

The 7 to 9 show different embodiments for attachment of a guide element 16 ,

The 7 shows a longitudinal spar 14 a frame which is arranged at the window opening. At the longitudinal spar 14 is the guide rail 1 arranged or integrated into this. At one end of the longitudinal spar 14 is the guide element 16 provided in the form of a frame end piece, which at the same time as storage for the winding roll 15 serves for the rollable element.

In the embodiment of the 8th shows the frame next to the longitudinal spar 14 a crossbeam 17 on, the longitudinal spar 14 with an opposite longitudinal spar (not shown) connects. The guide element 16 is in the frame cross member 17 integrated, with the winding roll 15 is additionally arranged on the frame cross member.

In the embodiment of the 9 is again a frame with longitudinal bars 14 and one Frame cross member 17 provided, wherein the guide rail 1 on the longitudinal spar 14 is arranged. The guide element 16 is just like the winding roll 15 on the frame cross member 17 arranged so that the rollable element of the winding roll 15 over the guide element 16 in the guide rail 1 can be introduced.

Overall, therefore, the embodiments of the 7 to 9 in that the guide elements can be arranged in different ways with respect to the guide rails. This is the guide element 16 always arranged so that the rollable element and in particular the flat main part 5 the roll-up element can be inserted without damage and in a smooth, smooth manner in the guide rails, however, the guide element 16 be attached to different locations, namely on the one hand to frame parts such as the longitudinal spar 14 and the frame cross member 17 , and on the other hand on the guide rail 1 directly. In addition, the guide element further functions, such as the storage of the winding shaft 15 , or in other components, such as the frame cross member 17 be integrated.

The 10 shows in a schematic representation how the guide element 16 or the corresponding guide element 18 with the guide rails 1 respectively. 2 and the winding roll 15 or cooperates thereon rolled up element.

As the 10 shows is the length of the winding roll 15 and thus the width of the flat main part 5 the rollable element along the longitudinal direction of the winding roll 15 smaller than the width of the flat body 5 in the tensioned state between the guide rails 1 and 2 , Accordingly, the guide elements run 16 and 18 in the plane of the flat main part 5 or a parallel plane apart. In addition, the guide elements 16 and 18 with their sliding surfaces relative to the plane of the flat main part 5 in the tensioned state between the guide rails 1 and 2 inclined, because the winding roll 15 below the level through the slits 6 and 7 the guide rails 1 and 2 is spanned, is arranged. Accordingly, the guide elements 16 and 18 the rollable element of the winding roll 15 on the one hand to the plane of the slots 6 and 7 and on the other hand they expand the rollable element in its tensioned state.

The 11 shows a perspective view of a guide element 16 , as it can be used in the previously described embodiments.

The guide element 16 has two wing areas 23 and 24 on, used to attach the guide element 16 serve and have corresponding openings for passing screws or the like. Between the wing elements 23 and 24 is formed a channel which is adapted in shape to the cross-sectional shape of the guide rails, wherein a connection side 22 is provided, by means of the guide element 16 can be connected to the end of a guide rail. There is a sliding surface on the channel 20 provided over which the rollable element slides. The sliding surface 20 has a rounded corner 21 on that is rounded so that the sliding surface 20 has both a height and a lateral slope, which serves to expand the retractable element or to bring and bring to the height position of the guide rail. Thus, a superposition of different inclined sliding surfaces is given.

Even though the present invention with reference to the accompanying embodiments has been described in detail, is for the expert of course, that changes and modifications the invention beyond the embodiments shown, especially in a different combination of individual features or omitting individual features is possible without the To leave the scope of the appended claims.
