Description

The invention relates to a pergola awning with at least two guide rails, on which a plurality of cross bars are movably mounted and between two transverse rungs each having a flexible shading element is arranged, wherein the circumferential direction in the outward front cross member a circumferential belt, in particular toothed belt and / or is fixed by means of which the foremost transverse rung can be moved as a pull profile in the extension direction to the front or in the retraction direction to the rear along the guide rails and wherein the further cross bars are free-running.

Such pergola awnings are known. A disadvantage of the known pergola awnings is that the method of free-running crossbars is undefined and can occur in the process of free-running crossbars unwanted noise.

The object of the invention is to overcome these disadvantages and to provide a pergola awning, which in particular has improved running properties.

This object is achieved by a pergola awning according to claim 1. Advantageous developments of the invention are specified in the subclaims.

Particularly advantageous in the pergola awning with at least two guide rails on which a plurality of cross bars are movably mounted and wherein between two cross bars each have a flexible shading element is arranged, wherein the circumferential direction in the outward front cross member a circumferential belt, in particular toothed belt and / or secured by means where the foremost cross rung is traversable as a pull profile in the extension direction to the front or in the retraction backwards along the guide rails and wherein the further cross bars are freewheeling, it is that the belt and the free-running crossbars are releasably coupled to each other.

Such pergola awnings have a plurality of transverse rungs which are arranged between lateral guide rails. The lateral guide rails thus define the extension direction. The transverse rung arranged in the rearward extension direction is fixed to the guide rails, i. not movable along the guide rails. At the front in the extension direction of the crosspiece engages a drive means such as a belt. By means of the drive means, the foremost transverse rung in the extension direction is moved forwards in the extension direction or moved backwards counter to the extension direction. In particular, a toothed belt with reinforcement can be used as the drive means.

Between the foremost in the extension direction of the crossbar and the rear fixed crossbar a plurality of free-running crossbars is arranged. Freewheeling refers to the fact that these crossbars along the guide rails are movable without a drive means acts directly on the free-running crossbars. In each case between two transverse rungs a flexible shading element is arranged and fixed to the two cross rungs. If the foremost transverse rung in the extension direction is extended in the extension direction, then gradually the individual shading elements arranged between the transverse rungs are tensioned and the respective next free-running transverse rung is pulled in the extension direction by means of the tensioned shading element.

Conversely, in a method of the foremost crossbar against the extension direction, the flexible shading elements are relaxed so that they hang freely between the cross bars. As soon as the foremost cross rung in a process runs counter to the extension direction on the subsequent free-running cross rung, this free-running crossbar is moved by means of the foremost driven cross bar against the extension direction. As soon as this package of cross rungs runs onto the next following freewheeling crossbar, this freewheeling crossbeam is also displaced counter to the extension direction and so on until the entire package of movable crossbars until it stops at the fixed, i. which is moved in the extension direction last cross rung.

The terms of the extension direction, in this sense foremost, first cross bar and rearmost, last cross rung serve to understand the function without this being a limitation to a particular arrangement, although in a conventional arrangement of such a pergola awning on the terrace on a wall of a House the direction of departure points away from the house. Such a pergola awning can serve as a sunscreen as well as a rain cover. The flexible shading elements may be formed by transparent and / or partially transparent and / or opaque elements. Individual sections of shading elements can each be arranged between the transverse rungs, or longer sections of shading elements can be arranged over a plurality of transverse rungs or a single shading element can be arranged over all the transverse rungs. Preferably, the shading element is in this case attached to the crossbars, respectively, to ensure a uniform extension and retraction.

Due to the releasable coupling of the belt and the free-running cross rungs the extension and retraction of the cross bars is defined. The freewheeling crossbars are free-running with respect to the guide rails and are, however, taken during the extension and retraction in a defined manner by the belt, which engages and / or attached to the foremost in the extension cross-rung and / or. In the case of the belt, the two Ends may be attached to the foremost crossbar and / or it may be an endless belt, which engages the foremost crossbar and this moves in the extension direction and retraction. The belt may be a timing belt.

Preferably, the belt and the free-running transverse rungs are frictionally and / or positively and / or positively and / or magnetically releasably coupled to each other. Thus, single or multiple types of coupling can be used and in particular combined. Thus, the coupling types are used to bring in and out of the free-running crossbars in a defined manner. As a result, an uncontrolled process of free-standing crossbars is avoided and it will improve the overall running characteristics of the crossbars.

Preferably, the belt exerts indirectly or directly on the movable transverse rungs, in particular at least on the freewheeling transverse rungs, a force with a component perpendicular to the course of the belt. This means that a force with a component perpendicular to the direction of movement of the belt on the crossbars is exerted indirectly or directly by the belt. By such a force component, the crossbars are guided relative to the guide rails in a defined manner, so that the running properties are improved and in particular rattling noises in the process of free-running crossbars are prevented.

In a preferred embodiment, the free-running transverse rungs and / or carriages, by means of which the free-running transverse rungs are movable on the guide rails, at their upper side in each case at least one contact region on which a serving as a drive means belt rests this contact area is the detachable, in particular frictional and / or magnetic coupling of belts and the freewheeling crossbars. In particular, the serving as a drive means belt and / or the cross bars or carriages on the Contact areas magnets which releasably magnetically couple the belt and the contact areas. When the magnetic holding force is exceeded, the magnets slide on each other during the extension of the pergola awning and the magnetic connection is released in a defined manner. When retracting the pergola awning, the magnetic connection is closed when the corresponding position of the crossbar relative to the belt is reached.

Preferably, the belt is guided over at least two deflection rollers, wherein the free-running transverse rungs and / or carriage, by means of which the free-running transverse rungs are movable on the guide rails, each have at least one contact area on its upper side, wherein the cross sections of the free-running transverse rungs at least in the contact areas the cross rungs protrude into the tensioning path of the lower belt of the belt.

The belt is thus guided over at least two pulleys. The cross-sections of the free-running transverse rungs are accordingly at least in the contact areas in which the belt rests on the free-running cross rungs and / or carriages, dimensioned such that they intersect the line, which results when a tangent is placed on the two pulleys over which the bottom of the belt is guided. The fact that this tangent is cut, the belt with its bottom is mandatory on the contact areas of the cross bars and / or carriage. As a result, on the one hand a compressive force with a component perpendicular to the running direction of the belt on the cross rungs and / or carriages exercised. Furthermore, there is a static friction between the belt and the cross bars and / or carriages in the contact areas, so that the cross bars are taken by the resting belt in a defined manner, until either two free-running transverse rungs lie together during retraction and the belt then over slides away the transverse rungs or in the opposite direction when extending the arranged between two transverse rungs flexible shading element is stretched and a further extension of the in this consideration in Extension direction front cross rung is prevented by the tensioned shading element.

Preferably, the crossbars are releasably coupled to each other. In particular, the transverse rungs can be coupled to one another magnetically and / or mechanically detachable. By such a coupling of the transverse rungs with each other, the method of the cross rungs in the extension and / or retraction can be further defined. In particular, an extension can take place in such a way that the freewheeling transverse rungs are pulled out successively from the front to the rear, so that in each case a flexible shading element is stretched between two cross rungs in the front region, before the extension of the next behind located cross rung takes place. As a result, with partially extended pergola awning, the shading between two retracted crossbars hangs down and the package of hanging shading elements hangs in the rear area and not disturbing in the front area above the terrace area. Rather, an extension in the extension direction takes place in such a way that initially the first shading element in the extension direction is tensioned and then the second shading element and so on, so that last in the extension last, rearmost shading element is stretched.

The releasable coupling of the cross bars can indirectly, for example via a detachable coupling of carriage, by means of which the cross rungs are mounted on the guide rails, carried out. The detachable coupling of the cross bars can be done alternatively or cumulatively also directly on the cross bars.

In the case of a magnetic coupling, the magnetic couplings of the individual transverse rungs can be provided with one another in such a way that the force required for solving the magnetic connection increases from the front to the rear in order to achieve a defined behavior of the transverse rungs when the pergola awning is extended. Accordingly, the magnetic connection between the first and the outward direction would be the first release the second transverse rung and, after the tensioning of the shading element between the first and second transverse rung, next release the magnetic connection between the second and third transverse rung in the extension direction, and so on. Also, by an appropriate selection of the magnetic connections, it can thus be effected and / or supported, that initially in the extension direction first shading element is stretched and then the second shading element and so on, so that last in the extension last, rearmost shading element is stretched.

Preferably, the belt has a plurality of carriers, which are positioned such that in each case a driver can engage with an associated crossbar. By such a driver, it can be ensured that each crossbar of the freewheeling crossbars in a defined manner with the corresponding driver on the belt engages and is moved in the desired manner.

In particular, each crossbar can be movably mounted on the guide rails by means of carriages. Furthermore, the crossbars may have dampers which damp the contact and in particular a coupling between two cross bars. Such dampers avoid unwanted noise when retracting the pergola awning. Alternatively or cumulatively, the carriages, by means of which the transverse rungs are movably mounted on the guide rails, have dampers which damp the contact and in particular a coupling between two transverse rungs.

An embodiment of the invention is illustrated in the figures and will be explained below. Show it:

FIG. 1

a section through the transverse rungs in the view on the inside of the guide rails;

FIG. 2

an enlarged view of detail A after FIG. 1 ,

FIG. 1 shows the section through the crossbars 10, 20, 30, 40 of a pergola awning. The representation according to Fig. 1 is only schematic and not to scale.

The transverse rungs 10, 20, 30, 40 of the pergola awning are mounted on the guide rail 1. The extension direction of the pergola awning is characterized by the arrow 2. At the front in the extension direction of the crossbar 10, the circulating toothed belt 3 is fixed. The toothed belt 3 is guided over the deflection rollers 4, 5, 6. The drive of the toothed belt 3 takes place in the retraction direction and in the extension direction by an electric motor acting on the deflection roller 6. By means of the attached to the foremost crossbar 10 toothed belt 3, the immediate process of the foremost crossbar 10 along the guide rail in the extension towards the front or back to the rear. In the illustrated embodiment, a drive means in the form of the toothed belt 3 is arranged on one side of the pergola awning. Alternatively, a drive means can also be arranged on both guide rails, which acts on both ends of the first cross member 10 and moves them in the extension direction 2 and in the retraction direction along the guide rails 1.

The arranged in relation to the extension direction behind the foremost crossbar 10 further crossbars 20, 30 are mounted on the guide rail 10 freewheeling. The rearmost in the extension direction crossbar 40 is fixed to the guide rail. This means that the rearmost in the extension direction 2 crossbar 40 is not movable. Between the cross rungs are arranged flexible shading elements 15, 25, 35. As in FIG. 1 shown schematically, which is between the viewed in the extension direction last free-running crossbar 30 and the rearmost in the fixed fixed crossbar 40 fixed shading element 35 stretched. This means that a further method of the free-running cross member 30 in the extension direction 2 is no longer possible. The crossbars 20, 30 are partially moved apart, so that the shading element 25 arranged therebetween has already been partially tensioned, as it is indicated by the reduced sagging of the shading element 25. The representation according to FIG. 1 is in this respect purely schematic and not to scale.

In a further method of the foremost crossbar 10 by means of the toothed belt 3 in the extension direction 2, all the shading elements 15, 25, 35 between the transverse rungs 10, 20, 30, 40 would be tensioned at maximum extended pergola awning. The pergola awning not only provides shade, but can also be used as a rain cover.

The storage of the cross bars 10, 20, 30 on the guide rails 1 by means of corresponding carriages 12, 22, 32, in turn, with corresponding rollers 13, 14, 23, 24, 33, 34 roll along a corresponding profile of the guide rail 1. An enlarged view of detail A after Fig. 1 shows Fig. 2 ,

The toothed belt 3 is guided over the deflection rollers 4, 5, 6. The free-running transport profiles 20, 30 have at the top of their carriages 22, 32 each have a contact region 21, 31, which is positioned and dimensioned such that it intersects the tangent between the deflection rollers 4, 5. Accordingly, the toothed belt 3 is necessarily on the contact areas 21, 31 and forms a frictional connection. This means that as long as the viewed in the extension direction behind the free-running crossbars 20, 30 shading elements 25, 35 are not fully tensioned, the free-running crossbars are taken by the frictional engagement at the contact portions 21, 31 of the toothed belt 3 in the extension direction. This results in a defined extension of the free-running transverse rungs 20, 30 in the extension 2.

Furthermore, the transverse rungs in the retracted position are coupled to one another by magnets 52, 53. As soon as the frontmost transverse rung 10 seen in the extension direction comes into contact with the following transverse rung 20, magnetic contact 52 is produced by the magnet 52 arranged on the carriage 22 of the second transverse rung 20. Likewise at a further retraction of the pergola awning by the magnet 53 on the carriage 32 of the next free-running crossbar 30 made the magnetic contact. As a result, the transverse rungs are releasably magnetically coupled to one another.

To avoid unwanted noise when retracting the pergola awning, the carriages 12, 22, 32 damping elements 50 which come when retracting the pergola awning against the extension direction 2 when pushing together the cross bars 10, 20, 30 in contact and vaping the contact accordingly. The dampers 50 are rubber buffers which are correspondingly reversibly deformable and prevent noise when the transverse rungs 10, 20, 30, 40 move together.
