Definitions

  • the invention relates to a pergola awning with at least two guide rails on which several cross rungs with a foremost cross rungs in the extension direction and at least one further cross rungs are movably mounted and a flexible shading element is arranged between two cross rungs, with a circumferential belt on the foremost cross rungs in the extension direction with a lower chord and an upper chord, in particular a toothed belt, engages and / or is fastened, by means of which at least the foremost transverse rungs can be moved as a tension profile in the extension direction forwards or in the retraction direction backwards along the guide rails, the belt over at least one drive roller and over at least one pulley is guided along a guideway.
  • Such pergola awnings are known, for example from EP 3 309 319 A1 .
  • the disadvantage of the known pergola awnings is that the running properties of the cross bars can deteriorate due to material expansion and / or changing environmental factors.
  • Pergola awnings are known in which belt tensioners are arranged with at least one tensioning roller rotatable about a tensioning roller axis, the tensioning roller protruding into the travel path of the belt in order to tension the belt.
  • the object of the invention is to overcome these disadvantages and in particular to provide a pergola awning which ensures improved, in particular constant, running properties for a longer period and / or with different environmental factors.
  • the pergola awning has at least one belt tensioner with at least one tensioning roller rotatable about a tensioning roller axis, which between a first position and at least one two ith position is displaceable, wherein the tensioning roller protrudes at least in the second position into the travel path of the
  • Such pergola awnings have a plurality of cross bars which are arranged between lateral guide rails.
  • the lateral guide rails thus define the direction of extension.
  • the transverse rungs arranged at the rear in the direction of extension is usually fixed to the guide rails, i.e. cannot be moved along the guide rails.
  • a belt engages the foremost cross rung in the direction of extension. By means of the belt, the foremost transverse rung in the extension direction is moved forwards in the extension direction or moved backwards in the retraction direction counter to the extension direction.
  • a toothed belt with reinforcement can be used as the belt.
  • a flexible shading element is arranged between two, in particular adjacent, cross rungs and is attached to the two cross rungs.
  • the further transverse rungs can run freely. If the foremost transverse rung in the extension direction is extended in the extension direction, the individual shading elements arranged between the transverse rungs are gradually tensioned and the next further free running transverse rungs are pulled in the extension direction by means of the tensioned shading element. Conversely, when the foremost cross rungs are moved against the extension direction in the retraction direction, the flexible shading elements are relaxed so that they hang freely down between the cross rungs. As soon as the foremost cross rung runs against the following further free-running cross rung during a movement against the extension direction, this free-running cross rung is displaced against the extension direction by means of the foremost driven cross rung.
  • this free running cross rungs is also shifted against the direction of extension and so on until the entire package of movable cross rungs has moved up to the stop on the fixed cross rung, i.e. the last cross rung in the extension direction.
  • the further transverse rungs can also be pulled directly or indirectly from the belt, so that the further transverse rungs are not free-running.
  • the cross bars can be gradually extended without the shading elements being stretched between the cross bars. They can also be retracted without colliding with each other.
  • the belt can act indirectly or directly, in particular by means of drivers and / or by means of a frictional connection and / or a force-locking connection and / or a form-locking connection and / or a material connection.
  • the circumferential belt can have the two ends attached to the foremost transverse rung and / or it can be an endless belt that engages the foremost transverse rung and moves it in the direction of extension and retraction.
  • the flexible shading elements can be formed by transparent and / or partially transparent and / or opaque elements. Individual sections of shading elements can each be arranged between the cross bars or longer sections of shading elements can be arranged across several cross bars or a single shading element can be arranged across all cross bars. In this case, the shading element is preferably fastened to the transverse rungs in order to ensure even extension and retraction.
  • the belt is guided at least, in particular at its first deflection point, via at least one drive roller and, in particular at its second deflection point, via at least one deflection roller along a travel path.
  • the fictitious path of the belt is defined, which is created by means of the drive roller and the deflection roller and possibly further deflection points as a tangent in a belt without any sagging.
  • the arrangement of the belt which is guided at least around the drive roller and the deflection roller, can also be referred to as a strand.
  • the lower chord and the upper chord alternate as a load run and an empty run, depending on whether the cross rungs are extended or retracted.
  • the pergola awning has at least one belt tensioner with at least one tensioning roller rotatable about a tensioning roller axis, which can be displaced between a first position and at least a second position, the tensioning roller protruding into the travel path of the belt at least in the second position, makes it possible to adjust the travel path of the belt and thus the tension of the belt by shifting the tensioning pulley.
  • the term belt tensioner encompasses the entire assembly, which includes at least the tensioning roller.
  • the tensioning pulley is displaceable in the direction of the belt and away from the belt.
  • the belt length can increase due to the use and / or due to the environmental factors, such as temperature and / or pressure and / or air humidity, so that the belt is less tensioned and / or sags more and thus its running properties change especially in relation to the cross bars.
  • the second position of the tension pulley is a changeable and not a fixed position.
  • the tensioning roller can only protrude into the travel path in the areas of the belt which are not around the drive roller and the deflecting roller and possibly further rollers.
  • the tensioning roller in its first position can also protrude into the travel path of the belt or be located outside the travel path.
  • the tensioning roller can rest against the belt in the first position. However, it does not have to protrude into the travel path of the belt.
  • the adjustability of the tensioning roller according to the invention into the second position, in which the tensioning roller protrudes into the travel path of the belt, in particular further than in the first position, enables the travel path of the belt to be lengthened and thus the tension of the belt to be increased. In this way, the running properties of the belt can be improved with a changed belt length.
  • the belt tensioner can accordingly also be referred to as a toothed belt tensioner.
  • the position of the tensioning roller can be adjustable on a straight path, circular path, elliptical path or any path of any shape.
  • the element forming the tension roller axis can be guided in a link guide which is arranged in the pergola awning, in particular in the guide rail or in the belt tensioner.
  • the link guide can be designed circular or elliptical or straight.
  • the tensioning roller can be mounted so that it can be displaced and fixed in the link guide, for example, by means of stub axles.
  • the deflection roller can be moved in the extension direction and in the retraction direction of the transverse rungs.
  • the deflection roller can be movably mounted, for example, in a link guide of the guide rail or it can be attached to a movable deflection roller tensioner. In this way the tension of the belt can also be adjusted. If the pulley is moved in the extension direction, the tension of the belt increases. If, on the other hand, the pulley is moved in the retraction direction, the tension on the belt is reduced.
  • a belt can be guided within a guide rail. Consequently, a drive roller, a deflection roller and a belt tensioner can be arranged in each guide rail.
  • the tensioning roller preferably presses against the belt by means of a defined force, in particular a spring force.
  • the tensioning roller is tensioned against the belt by means of a defined force, in particular a spring force.
  • a defined force in particular a spring force.
  • against the belt means towards that Belt so that the defined force, in particular spring force, counteracts a displacement of the tensioning roller away from the belt. This pressure exerted on the belt by the tension pulley deflects and tensions the belt.
  • the tensioning roller can be pressed against the belt by means of a pneumatic force.
  • the belt is always tensioned by means of a defined force, so that the running properties of the belt can be kept constant regardless of its length of use-related and / or environmental-factor-related expansion.
  • an elongation of the belt relative to the guide rail can in particular be the result of different thermal expansion coefficients of the belt and the guide rails.
  • the pergola awning is usually installed during the initial assembly in such a way that the belt is tensioned to the desired tension.
  • the existing tension of the belt and the defined force of the tensioning roller by means of which the tensioning roller presses against the belt, compensates for the forces exerted on one another by the belt and the tensioning roller.
  • the desired tension can be dimensioned in such a way that the tensioning roller is displaced at least a little way into the travel path of the lower chord or the upper chord.
  • the tensioning pulley which can be displaced towards and away from the belt and which presses against the belt by means of a defined force, in particular a spring force, ensures that the belt is always tensioned at least by means of the defined force exerted by the tensioning pulley.
  • Such an automatically adjustable tensioning roller achieves a further advantage over the prior art in that the tensioning roller or its position serves as an indicator for the currently existing tension of the belt when the pergola awning is being installed. In this way, the tension can be read off rationally during the initial assembly by means of the position of the tensioning roller and, if necessary, adjusted to the desired tension. This was not possible with the known prior art, in which the tension of the belt could only be felt over the belt.

  • the other end of the arm is firmly fixed at least with regard to its position.
  • the tensioning roller can by means of two arms be rotatably mounted.
  • the torsion bar axis describes the axis around which the arm is rotatably mounted. In this way, the spring force of the torsion bar spring counteracts a displacement of the tensioning roller about the torsion bar axis away from the belt. In this way, a particularly advantageous construction is implemented, which ensures a stable and simple arrangement.

This was not possible with the known prior art, in which tension in the belt could only be felt over the belt.
  • the opening can be made very narrow so that it can just reach through an extension of the axis of rotation of the tensioning roller and thus the position of the tensioning roller can be read, even if the tensioning roller itself is not clearly visible through such a narrow opening.
  • a cover can be arranged to cover the opening in order not to impair the visual impression of the awning.
  • the deflection roller is preferably arranged on the belt tensioner or a deflection roller carrier, which can be moved on one of the guide rails in the extension direction and in the retraction direction of the cross rungs, the belt tensioner and / or the deflection roller carrier having at least one positive and / or at least one negative guide profile that interacts with at least one negative and / or at least one positive guide profile in the guide rail.

Because this tangent is cut, the belt with its lower chord necessarily rests on the contact areas of the transverse rungs and / or carriage. As a result, on the one hand, a compressive force with a component perpendicular to the direction of travel of the belt is exerted on the transverse rungs and / or carriage.
