Definitions

  • the invention relates to a canopy with at least two lateral supports, on which several slats are each pivotably mounted about an axis of rotation, the axes of rotation of the slats running from one support to the other support and each having a longitudinal extent limited by a first side and an opposite second side , wherein the slats can be pivoted from a closed position, in which the slats form a closed roof surface, into any open position, in particular, the slats being kinematically coupled to one another by means of at least one coupling rod.
  • a slatted roof is known in which a tilting moment compensation means is mechanically coupled to the slats in order to counteract an unwanted over-rotation of the slats in the open position of the slats.
  • a slatted roof is known in which balancing springs are arranged to partially compensate for the torque caused by the weight of the slats about their hinge axis in those slats whose hinge axis is along a longitudinal edge of the slats. This is intended to make it easier to rotate into the open position.
  • a disadvantage of known canopies is that the slats can move slightly out of the closed position when the engine is switched off, which can cause the slats to rattle and the roof surface to leak.
  • the object of the invention is to overcome the disadvantages of known canopies and to develop a canopy in such a way that unwanted play and the associated rattling of the slats in the closed position of the slats is prevented and the roof surface is reliably sealed in the closed position of the slats.
  • the compression spring is arranged in such a way that even when the slats are in the closed position, a compressive force is exerted on the coupling rod in the closing direction of the slats. This will create an unwanted game and hence associated rattling of the slats is prevented when the slats are in the closed position and the roof surface is reliably sealed against rain when the slats are in the closed position.
  • the compression spring can act directly or indirectly on the coupling rod and/or directly or indirectly on at least one slat and exert a compressive force in the closing direction of the slats on the coupling rod and/or the slat.
  • the coupling rod is used for the kinematically coupled, in particular synchronous, pivoting of the slats.
  • the compressive force in the closing direction of the slats is always transmitted to all slats at the same time, regardless of whether the free end of the compression spring is directly or indirectly attached to the coupling rod and / or directly or indirectly attacks at least one lamella.
  • the opening of the roof or the slats is understood synonymously with pivoting the slats into an open position.
  • the arbitrary open position of the slats means a position deviating from the closed position by turning through any desired angle from the closed position, in particular up to 360°.
  • the pivoting of the slats can take place in particular by means of an electric and/or manual drive, which acts on at least one or more slats and/or on the coupling rod.
  • the axes of rotation of the slats can run horizontally or at an acute angle, in particular from 1° to 45° to the horizontal.
  • the axes of rotation of the slats run directly or indirectly from one carrier directly or indirectly to the other carrier, with the actual longitudinal extension of the slat being able to be less than or equal to or greater than the distance between the carriers.
  • each lamella can be formed by a longitudinal profile, in particular a hollow profile.
  • the longitudinal profile of each slat can be formed in one piece or in multiple parts, in particular from a plurality of longitudinal profiles connected in a form-fitting and/or force-fitting and/or cohesive manner.
  • the lamellae can each have a continuous cross section.
  • the slats can be arranged inclined relative to the horizontal with respect to their longitudinal extent. Such an inclination is used to drain rainwater hitting the closed slatted roof to one side of the roofing.
  • the slats can each be pivoted about an axis of rotation running parallel to their longitudinal extent. Furthermore, the individual slats can be wider than the center distance between the slats corresponds to.
  • the term “width of the lamella” designates the extent of the lamella perpendicular to its axis of rotation running parallel to its longitudinal extent. As a result, the slats overlap in the closed position, creating a rainproof roof surface.
  • the slats can have angle profiles on the edges running parallel to the axis of rotation, which intermesh when the slats are in the closed state.
  • the axes of rotation of the slats can run through the centroid of their cross section, i.e. the slats are preferably mounted such that they can pivot about their axis of rotation and the slat profile is designed in such a way that the slats themselves do not generate any resulting torque due to their own weight, regardless of their angular position.
  • the slats can be inclined relative to the horizontal in the direction of their axis of rotation, in order to allow rainwater to be drained towards one of the two lateral beams.
  • the carriers can run parallel to one another.
  • the carriers can extend at an angle to one another, with the longitudinal extent of the successive lamellae decreasing correspondingly to the distance between the carriers.
  • the two carriers can each be mounted on a part of the building.
  • one of the supports can be mounted on a part of a building.
  • the carrier can be supported on the other side by means of at least one post, in particular a vertical one.
  • the canopy can be mounted free-standing and supported by a plurality of posts, particularly vertical ones.
  • the pressure spring is preferably a gas pressure spring, in particular the gas pressure spring can have a protective casing, in particular the piston rod of the gas pressure spring can be surrounded by a protective tube.
  • a protective casing offers permanent protection of the gas pressure spring and in particular the piston rod of the gas pressure spring against environmental influences and dirt. This ensures safe long-term operation of the gas spring.
  • the canopy preferably has at least one electric drive for pivoting the slats, which acts on at least one or more slats and/or on the coupling rod and/or is arranged in a slat and drives this slat.
  • the canopy itself can have a control unit and/or be controlled by an external control unit, which controls the drive.
  • the control unit can be connected to the canopy by means of a cable and/or wirelessly, in particular by means of an infrared connection and/or a Bluetooth connection and/or a radio connection.
  • the canopy has at least one electric drive for pivoting the slats, the electric drive having an emergency release so that after the emergency release of the electric drive has been triggered, the slats are automatically pivoted into the closed position by means of the compression spring.
  • the user has the option of triggering the emergency release of the electric drive and thus kinematically decoupling the no longer functional electric drive from the slats.
  • the emergency release is triggered manually by the user. This means that triggering the emergency release corresponds to a kinematic decoupling of the electric drive from the coupling rod and the slats.
  • the slats Due to the kinematic decoupling of the electric drive from the slats, the slats are thus pivoted into the closed position and held in the closed position after the emergency release of the electric drive has been triggered by means of the compression spring. Even if the electric drive for pivoting the slats fails, the user can close the slatted roof at any time. This is made possible by the particularly advantageous combination of a compression spring that always exerts a compressive force in the closing direction of the slats on the coupling rod and/or at least one slat, and the emergency release of the electric drive.
  • a head plate is arranged on the first side of the slats, the head plates of the slats being pivotably coupled to the coupling rod via a coupling pin and at least one friction element being arranged between the coupling rod and at least one of the head plates, in particular each head plate , which is directly or indirectly in contact with the coupling rod and / or with the top plate.

  • the coupling rod serves for the kinematically coupled, in particular synchronous, pivoting of the slats.
  • the top plates of the slats are each pivotally coupled to the coupling rod via a coupling pin.
  • this does not mean that the coupling rod assumes a rigid position while the head plates are pivoted. Rather, when the slats are pivoted, both the head laths and the coupling rod move in relation to one another.
  • the top plate should be coupled as firmly as possible to the coupling rod in order to ensure a stable position of the slats.
  • the top plate should be as easy as possible to move relative to the coupling rod in order to allow easy pivoting of the slats.
  • the friction element creates a balance between these two requirements.
  • the friction element between the top plate and the coupling rod acts as a friction brake, so that it brakes or dampens a relative movement of the top plate with respect to the coupling rod.
  • the top plate is better coupled to the coupling rod and consequently also to the other slats coupled to the coupling rod.
  • the assembly of the slats and the coupling rod is thus stabilized. This effectively prevents the slats from rattling, since the wind would now have to move the entirety of the slats in connection with the coupling rod while the mobility of the top plate relative to the coupling rod is damped by the friction element in order to cause rattling. This is effectively prevented by the arrangement of the friction element according to the invention.
  • the friction element When a single friction element is arranged, the friction element is accordingly in direct or indirect contact both with the top plate and with the coupling rod.
  • the friction element is indirectly connected to the Top plate and/or the coupling rod in contact when further intermediate elements, such as a seal and/or a disc, in particular a washer, are arranged between the friction element and the top plate and/or the coupling rod. Accordingly, the friction element is in direct contact with the top plate and/or the coupling rod if no further intermediate elements are arranged between the friction element and the top plate and/or the coupling rod.
  • one of the friction elements is in direct or indirect contact with the head plate, while another of the friction elements is in direct or indirect contact with the coupling rod, so that overall the movement between the head plate and the coupling rod is damped.

  • the compression spring allows possible tolerances in the geometry of the individual components and/or possible through the service life or through Weather conditions, in particular temperature fluctuations, to compensate for changes in the geometry of the roofing. This enables the canopy to operate correctly.

Description

Die Erfindung betrifft eine Überdachung mit zumindest zwei seitlichen Trägern, an denen mehrere Lamellen jeweils um eine Drehachse verschwenkbar gelagert sind, wobei die Drehachsen der Lamellen von einem Träger zum anderen Träger verlaufen und jeweils eine von einer ersten Seite und einer gegenüberliegenden zweiten Seite begrenzte Längserstreckung aufweisen, wobei die Lamellen von einer Schließstellung, in der die Lamellen eine geschlossene Dachfläche bilden, in eine insbesondere beliebige Öffnungsstellung verschwenkbar sind, wobei die Lamellen mittels zumindest einer Kopplungsstange kinematisch miteinander gekoppelt sind.The invention relates to a canopy with at least two lateral supports, on which several slats are each pivotably mounted about an axis of rotation, the axes of rotation of the slats running from one support to the other support and each having a longitudinal extent limited by a first side and an opposite second side , wherein the slats can be pivoted from a closed position, in which the slats form a closed roof surface, into any open position, in particular, the slats being kinematically coupled to one another by means of at least one coupling rod.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved according to the invention by a canopy according to claim 1. Advantageous developments of the invention are specified in the dependent claims.

Besonders vorteilhaft bei der Überdachung mit zumindest zwei seitlichen Trägern, an denen mehrere Lamellen jeweils um eine Drehachse verschwenkbar gelagert sind, wobei die Drehachsen der Lamellen von einem Träger zum anderen Träger verlaufen und jeweils eine von einer ersten Seite und einer gegenüberliegenden zweiten Seite begrenzte Längserstreckung aufweisen, wobei die Lamellen von einer Schließstellung, in der die Lamellen eine geschlossene Dachfläche bilden, in eine insbesondere beliebige Öffnungsstellung verschwenkbar sind, wobei die Lamellen mittels zumindest einer Kopplungsstange kinematisch miteinander gekoppelt sind, ist es, dass zumindest eine Druckfeder derart zwischen einem Träger und der Kopplungsstange und/oder zumindest einer Lamelle angeordnet ist, dass ein festes Ende der Druckfeder an dem Träger angreift, während ein freies Ende der Druckfeder an der Kopplungsstange und/oder an der Lamelle angreift und stets eine Druckkraft in Schließrichtung der Lamellen auf die Kopplungsstange und/oder die Lamelle ausübt.Particularly advantageous in the case of the canopy with at least two lateral supports, on which several slats are each pivotably mounted about an axis of rotation, the axes of rotation of the slats running from one support to the other support and each having a longitudinal extent limited by a first side and an opposite second side , wherein the slats can be pivoted from a closed position, in which the slats form a closed roof surface, into any particular open position, wherein the slats are kinematically coupled to one another by means of at least one coupling rod, it is that at least one compression spring is positioned between a carrier and the Coupling rod and/or at least one lamella is arranged such that a fixed end of the compression spring acts on the carrier, while a free end of the compression spring acts on the coupling rod and/or on the lamella and always exerts a compressive force in the closing direction of the lamella on the coupling rod and/or or exercising the lamella.

Dabei ist die Druckfeder derart angeordnet, sodass auch in der geschlossenen Position der Lamellen eine Druckkraft in Schließrichtung der Lamellen auf die Kopplungsstange ausgeübt wird. Hierdurch wird ein ungewolltes Spiel und damit verbundenes Klappern der Lamellen in der Schließstellung der Lamellen verhindert und die Dachfläche wird in der Schließstellung der Lamellen zuverlässig regendicht abgedichtet.The compression spring is arranged in such a way that even when the slats are in the closed position, a compressive force is exerted on the coupling rod in the closing direction of the slats. This will create an unwanted game and hence associated rattling of the slats is prevented when the slats are in the closed position and the roof surface is reliably sealed against rain when the slats are in the closed position.

Dabei kann die Druckfeder unmittelbar oder mittelbar an der Kopplungsstange und/oder unmittelbar oder mittelbar an zumindest einer Lamelle angreifen und eine Druckkraft in Schließrichtung der Lamellen auf die Kopplungsstange und/oder die Lamelle ausüben. Die Kopplungsstange dient dabei dem kinematisch gekoppelten insbesondere synchronen Verschwenken der Lamellen.The compression spring can act directly or indirectly on the coupling rod and/or directly or indirectly on at least one slat and exert a compressive force in the closing direction of the slats on the coupling rod and/or the slat. The coupling rod is used for the kinematically coupled, in particular synchronous, pivoting of the slats.

Durch die kinematische Kopplung der Lamellen über die Kopplungsstange, die beispielsweise als Vierkant aus Flachmaterial gebildet sein kann, wird die Druckkraft in Schließrichtung der Lamellen stets auf alle Lamellen gleichzeitig übertragen, unabhängig davon, ob das freie Ende der Druckfeder unmittelbar oder mittelbar an der Kopplungsstange und/oder unmittelbar oder mittelbar an zumindest einer Lamelle angreift.Due to the kinematic coupling of the slats via the coupling rod, which can be formed as a square from flat material, for example, the compressive force in the closing direction of the slats is always transmitted to all slats at the same time, regardless of whether the free end of the compression spring is directly or indirectly attached to the coupling rod and / or directly or indirectly attacks at least one lamella.

Das Öffnen der Überdachung bzw. der Lamellen wird synonym zum Verschwenken der Lamellen in eine Öffnungsstellung verstanden. Mit der beliebigen Öffnungsstellung der Lamellen ist eine von der Schließstellung abweichende Stellung durch Verdrehen um einen beliebigen Winkel aus der Schließstellung heraus insbesondere bis 360° gemeint.The opening of the roof or the slats is understood synonymously with pivoting the slats into an open position. The arbitrary open position of the slats means a position deviating from the closed position by turning through any desired angle from the closed position, in particular up to 360°.

Das Verschwenken der Lamellen kann dabei insbesondere mittels eines elektrischen und/oder manuellen Antriebs erfolgen, welcher an zumindest einer oder mehreren Lamellen und/oder an der Kopplungsstange angreift.The pivoting of the slats can take place in particular by means of an electric and/or manual drive, which acts on at least one or more slats and/or on the coupling rod.

Die Drehachsen der Lamellen können dabei horizontal oder unter einem spitzen Winkel insbesondere von 1° bis 45° zur Horizontalen verlaufen. Dabei verlaufen die Drehachsen der Lamellen mittelbar oder unmittelbar von einem Träger mittelbar oder unmittelbar zum anderen Träger, wobei die tatsächliche Längserstreckung der Lamelle kleiner oder gleich oder größer als der Abstand zwischen den Trägern sein kann.The axes of rotation of the slats can run horizontally or at an acute angle, in particular from 1° to 45° to the horizontal. The axes of rotation of the slats run directly or indirectly from one carrier directly or indirectly to the other carrier, with the actual longitudinal extension of the slat being able to be less than or equal to or greater than the distance between the carriers.

Insbesondere kann jede Lamelle durch ein Längsprofil, insbesondere Hohlprofil, gebildet sein. Das Längsprofil jeder Lamelle kann einteilig oder mehrteilig, insbesondere aus mehreren formschlüssig und/oder kraftschlüssig und/oder stoffschlüssig verbundenen Längsprofilen, gebildet sein.In particular, each lamella can be formed by a longitudinal profile, in particular a hollow profile. The longitudinal profile of each slat can be formed in one piece or in multiple parts, in particular from a plurality of longitudinal profiles connected in a form-fitting and/or force-fitting and/or cohesive manner.

Insbesondere können die Lamellen jeweils einen durchgehenden Querschnitt aufweisen. Insbesondere können die Lamellen bezüglich ihrer Längserstreckung gegenüber der Horizontalen geneigt angeordnet sein. Eine derartige Neigung dient der Abfuhr von auf das geschlossene Lamellendach auftreffende Regenwasser zu einer Seite der Überdachung.In particular, the lamellae can each have a continuous cross section. In particular, the slats can be arranged inclined relative to the horizontal with respect to their longitudinal extent. Such an inclination is used to drain rainwater hitting the closed slatted roof to one side of the roofing.

Insbesondere können die Lamellen jeweils um eine parallel zu ihrer Längserstreckung verlaufende Drehachse verschwenkbar gelagert sein. Ferner können die einzelnen Lamellen breiter sein, als es dem Achsabstand der Lamellen untereinander entspricht. Mit dem Begriff der Breite der Lamelle ist die Erstreckung der Lamelle senkrecht zu ihrer parallel zu ihrer Längserstreckung verlaufenden Drehachse bezeichnet. Hierdurch überlappen sich die Lamellen in der geschlossenen Stellung, sodass eine regendichte Dachfläche entsteht. Die Lamellen können an den parallel zur Drehachse verlaufenden Kanten Winkelprofile aufweisen, die im geschlossenen Zustand der Lamellen ineinandergreifen.In particular, the slats can each be pivoted about an axis of rotation running parallel to their longitudinal extent. Furthermore, the individual slats can be wider than the center distance between the slats corresponds to. The term “width of the lamella” designates the extent of the lamella perpendicular to its axis of rotation running parallel to its longitudinal extent. As a result, the slats overlap in the closed position, creating a rainproof roof surface. The slats can have angle profiles on the edges running parallel to the axis of rotation, which intermesh when the slats are in the closed state.

Die Drehachsen der Lamellen können durch den Flächenschwerpunkt ihres Querschnittes verlaufen, d.h. dass die Lamellen bevorzugt derart verschwenkbar um ihre Drehachse gelagert und das Lamellenprofil derart ausgestaltet ist, sodass die Lamellen selbst aufgrund ihres Eigengewichtes unabhängig von ihrer Winkelposition kein resultierendes Drehmoment erzeugen.The axes of rotation of the slats can run through the centroid of their cross section, i.e. the slats are preferably mounted such that they can pivot about their axis of rotation and the slat profile is designed in such a way that the slats themselves do not generate any resulting torque due to their own weight, regardless of their angular position.

Die Lamellen können in Richtung ihrer Drehachse gegenüber der Horizontalen geneigt sein, um eine Ableitung von Regenwasser in Richtung auf einen der beiden seitlichen Träger zu ermöglichen.The slats can be inclined relative to the horizontal in the direction of their axis of rotation, in order to allow rainwater to be drained towards one of the two lateral beams.

Insbesondere können die Träger parallel zueinander verlaufen. Insbesondere können die Träger in einem Winkel zueinander verlaufen, wobei die Längserstreckung der aufeinanderfolgenden Lamellen korrespondierend zu dem Abstand zwischen den Trägern abnimmt.In particular, the carriers can run parallel to one another. In particular, the carriers can extend at an angle to one another, with the longitudinal extent of the successive lamellae decreasing correspondingly to the distance between the carriers.

Die zwei Träger können dabei jeweils an einem Gebäudeteil montiert sein. Alternativ kann einer der Träger an einem Gebäudeteil montiert sein. In dem Fall kann der Träger auf der anderen Seite mittels zumindest eines insbesondere senkrechten Pfostens gestützt werden. Alternativ kann die Überdachung freistehend montiert sein und von mehreren insbesondere senkrechten Pfosten getragen werden.The two carriers can each be mounted on a part of the building. Alternatively, one of the supports can be mounted on a part of a building. In that case, the carrier can be supported on the other side by means of at least one post, in particular a vertical one. Alternatively, the canopy can be mounted free-standing and supported by a plurality of posts, particularly vertical ones.

Vorzugsweise handelt es sich bei der Druckfeder um eine Gasdruckfeder, insbesondere kann die Gasdruckfeder eine Schutzummantelung aufweisen, insbesondere kann die Kolbenstange der Gasdruckfeder von einem Schutzrohr umgeben sein. Eine derartige Schutzummantelung bietet neben einer vorteilhaften optischen Gestaltung einen dauerhaften Schutz der Gasdruckfeder und insbesondere der Kolbenstange der Gasdruckfeder gegenüber Umwelteinflüssen und Verschmutzungen. Hierdurch wird ein sicherer Langzeitbetrieb der Gasdruckfeder gewährleistet.The pressure spring is preferably a gas pressure spring, in particular the gas pressure spring can have a protective casing, in particular the piston rod of the gas pressure spring can be surrounded by a protective tube. In addition to an advantageous optical design, such a protective casing offers permanent protection of the gas pressure spring and in particular the piston rod of the gas pressure spring against environmental influences and dirt. This ensures safe long-term operation of the gas spring.

Vorzugsweise weist die Überdachung zumindest einen elektrischen Antrieb zum Verschwenken der Lamellen auf, welcher an zumindest einer oder mehreren Lamellen und/oder an der Kopplungsstange angreift und/oder in einer Lamelle angeordnet ist und diese Lamelle antreibt.The canopy preferably has at least one electric drive for pivoting the slats, which acts on at least one or more slats and/or on the coupling rod and/or is arranged in a slat and drives this slat.

Insbesondere kann die Überdachung selbst eine Steuereinheit aufweisen und/oder von einer externen Steuereinheit angesteuert werden, welche den Antrieb ansteuert. Hierzu kann die Steuereinheit mit der Überdachung mittels eines Kabels und/oder kabellos, insbesondere mittels einer Infrarot-Verbindung und/oder einer Bluetooth-Verbindung und/oder einer Funkverbindung, verbunden sein.In particular, the canopy itself can have a control unit and/or be controlled by an external control unit, which controls the drive. For this purpose, the control unit can be connected to the canopy by means of a cable and/or wirelessly, in particular by means of an infrared connection and/or a Bluetooth connection and/or a radio connection.

In einer besonders bevorzugten Ausführungsform weist die Überdachung zumindest einen elektrischen Antrieb zum Verschwenken der Lamellen auf, wobei der elektrische Antrieb eine Notentriegelung aufweist, sodass nach Auslösung der Notentriegelung des elektrischen Antriebs die Lamellen mittels der Druckfeder automatisch in die Schließstellung verschwenkt werden.In a particularly preferred embodiment, the canopy has at least one electric drive for pivoting the slats, the electric drive having an emergency release so that after the emergency release of the electric drive has been triggered, the slats are automatically pivoted into the closed position by means of the compression spring.

Bei Ausfall des elektrischen Antriebs zum Verschwenken der Lamellen hat in diesem Fall der Benutzer die Möglichkeit, die Notentriegelung des elektrischen Antriebs auszulösen und damit den nicht mehr funktionsfähigen elektrischen Antrieb kinematisch von den Lamellen zu entkoppeln. Die Auslösung der Notentriegelung erfolgt manuell durch den Benutzer. Das bedeutet, dass das Auslösen der Notentriegelung einer kinematischen Entkopplung des elektrischen Antriebs von der Kopplungsstange und den Lamellen entspricht.In this case, if the electric drive for pivoting the slats fails, the user has the option of triggering the emergency release of the electric drive and thus kinematically decoupling the no longer functional electric drive from the slats. The emergency release is triggered manually by the user. This means that triggering the emergency release corresponds to a kinematic decoupling of the electric drive from the coupling rod and the slats.

Durch die kinematische Entkopplung des elektrischen Antriebs von den Lamellen werden die Lamellen somit nach Auslösung der Notentriegelung des elektrischen Antriebs mittels der Druckfeder in die Schließstellung verschwenkt und in der Schließstellung gehalten. Auch bei Ausfall des elektrischen Antriebs zum Verschwenken der Lamellen ist somit ein Schließen des Lamellendaches für den Benutzer jederzeit möglich. Ermöglicht wird dies durch die besonders vorteilhafte Kombination einer stets eine Druckkraft in Schließrichtung der Lamellen auf die Kopplungsstange und/oder zumindest eine Lamelle ausübende Druckfeder und die Notentriegelung des elektrischen Antriebs.Due to the kinematic decoupling of the electric drive from the slats, the slats are thus pivoted into the closed position and held in the closed position after the emergency release of the electric drive has been triggered by means of the compression spring. Even if the electric drive for pivoting the slats fails, the user can close the slatted roof at any time. This is made possible by the particularly advantageous combination of a compression spring that always exerts a compressive force in the closing direction of the slats on the coupling rod and/or at least one slat, and the emergency release of the electric drive.

In einer bevorzugten Ausführungsform ist an der ersten Seite der Lamellen jeweils eine Kopfplatte angeordnet, wobei die Kopfplatten der Lamellen jeweils über einen Kopplungsstift schwenkbar an der Kopplungsstange gekoppelt sind und zwischen der Kopplungsstange und zumindest einer der Kopfplatten, insbesondere jeder Kopfplatte, zumindest ein Reibelement angeordnet ist, welches mittelbar oder unmittelbar in Kontakt mit der Kopplungsstange und/oder mit der Kopfplatte steht.In a preferred embodiment, a head plate is arranged on the first side of the slats, the head plates of the slats being pivotably coupled to the coupling rod via a coupling pin and at least one friction element being arranged between the coupling rod and at least one of the head plates, in particular each head plate , which is directly or indirectly in contact with the coupling rod and / or with the top plate.

Dabei ist die Kopfplatte fest mit der Lamelle, insbesondere kraftschlüssig und/oder stoffschlüssig und/oder formschlüssig, verbunden. Der Kopplungsstift kann dabei beispielweise als Schraube in Verbindung mit einer Mutter ausgeführt sein.In this case, the top plate is firmly connected to the lamella, in particular in a force-fitting manner and/or in a material-fitting manner and/or in a form-fitting manner. The coupling pin can be designed, for example, as a screw in connection with a nut.

Die Kopplungsstange dient dabei wie erläutert dem kinematisch gekoppelten insbesondere synchronen Verschwenken der Lamellen. Dabei sind die Kopfplatten der Lamellen jeweils über einen Kopplungsstift schwenkbar an der Kopplungsstange gekoppelt. Damit ist jedoch nicht gemeint, dass die Kopplungsstange eine starre Position einnimmt, während die Kopfplatten verschwenkt werden. Vielmehr bewegen sich beim Verschwenken der Lamellen sowohl die Kopflatten als auch die Kopplungsstange gegenüber einander.As explained, the coupling rod serves for the kinematically coupled, in particular synchronous, pivoting of the slats. The top plates of the slats are each pivotally coupled to the coupling rod via a coupling pin. However, this does not mean that the coupling rod assumes a rigid position while the head plates are pivoted. Rather, when the slats are pivoted, both the head laths and the coupling rod move in relation to one another.

Grundsätzlich soll einerseits die Kopfplatte möglichst fest mit der Kopplungsstange gekoppelt sein, um eine stabile Stellung der Lamellen zu gewährleisten. Andererseits soll dabei die Kopfplatte möglichst einfach gegenüber der Kopplungsstange bewegbar sein, um ein leichtes Verschwenken der Lamellen zu ermöglichen.Basically, on the one hand, the top plate should be coupled as firmly as possible to the coupling rod in order to ensure a stable position of the slats. On the other hand, the top plate should be as easy as possible to move relative to the coupling rod in order to allow easy pivoting of the slats.

Dabei stellt das Reibelement ein Gleichgewicht zwischen diesen beiden Anforderungen her. Dabei wirkt das Reibelement zwischen der Kopfplatte und der Kopplungsstange als Reibbremse, sodass es eine relative Bewegung der Kopfplatte gegenüber der Kopplungsstange bremst bzw. dämpft. Auf diese Weise wird die Kopfplatte unabhängig von der Stellung der Lamelle besser mit der Kopplungsstange und folglich auch mit den anderen an der Kopplungsstange gekoppelten Lamellen gekoppelt. Die Gesamtheit aus den Lamellen und der Kopplungsstange wird somit stabilisiert. Dadurch wird ein Klappern der Lamellen wirksam verhindert, da der Wind nun die Gesamtheit aus den Lamellen in Verbindung mit der Kopplungsstange bei gleichzeitig mittels des Reibelementes gedämpfter Beweglichkeit der Kopfplatte gegenüber der Kopplungsstange in Bewegung versetzen müsste, um ein Klappern zu verursachen. Dies wird durch die erfindungsgemäße Anordnung des Reibelementes wirksam unterbunden.The friction element creates a balance between these two requirements. The friction element between the top plate and the coupling rod acts as a friction brake, so that it brakes or dampens a relative movement of the top plate with respect to the coupling rod. In this way, regardless of the position of the slat, the top plate is better coupled to the coupling rod and consequently also to the other slats coupled to the coupling rod. The assembly of the slats and the coupling rod is thus stabilized. This effectively prevents the slats from rattling, since the wind would now have to move the entirety of the slats in connection with the coupling rod while the mobility of the top plate relative to the coupling rod is damped by the friction element in order to cause rattling. This is effectively prevented by the arrangement of the friction element according to the invention.

Bei Anordnung eines einzigen Reibelements steht das Reibelement dementsprechend sowohl mit der Kopfplatte als auch mit der Kopplungsstange mittelbar oder unmittelbar in Kontakt. Mittelbar steht das Reibelement mit der Kopfplatte und/oder der Kopplungsstange in Kontakt, wenn zwischen dem Reibelement und der Kopfplatte und/oder der Kopplungsstange weitere Zwischenelemente, wie bspw. eine Dichtung und/oder eine Scheibe, insbesondere Unterlegscheibe angeordnet sind. Dementsprechend steht das Reibelement mit der Kopfplatte und/oder der Kopplungsstange unmittelbar in Kontakt, wenn zwischen dem Reibelement und der Kopfplatte und/oder der Kopplungsstange keine weiteren Zwischenelemente angeordnet sind.When a single friction element is arranged, the friction element is accordingly in direct or indirect contact both with the top plate and with the coupling rod. The friction element is indirectly connected to the Top plate and/or the coupling rod in contact when further intermediate elements, such as a seal and/or a disc, in particular a washer, are arranged between the friction element and the top plate and/or the coupling rod. Accordingly, the friction element is in direct contact with the top plate and/or the coupling rod if no further intermediate elements are arranged between the friction element and the top plate and/or the coupling rod.

Bei Anordnung mehrerer Reibelemente steht eins der Reibelemente dementsprechend mit der Kopfplatte mittelbar oder unmittelbar in Kontakt, während ein anderes der Reibelemente mit der Kopplungsstange mittelbar oder unmittelbar in Kontakt steht, sodass insgesamt eine Dämpfung der Bewegung zwischen der Kopfplatte und der Kopplungsstange erfolgt. Auch hierbei ist die Anordnung weiterer Zwischenelemente zwischen den Reibelementen möglich.If several friction elements are arranged, one of the friction elements is in direct or indirect contact with the head plate, while another of the friction elements is in direct or indirect contact with the coupling rod, so that overall the movement between the head plate and the coupling rod is damped. Here, too, the arrangement of further intermediate elements between the friction elements is possible.

Der Begriff Kopplungsstange impliziert dabei nicht zwangsläufig eine zylindrische Ausbildung der Kopplungsstange. Insbesondere kann die Kopplungsstange somit einen runden, einen ovalen, einen rechteckigen, einen dreieckigen oder einen vieleckigen Querschnitt aufweisen. Insbesondere kann die Kopplungsstange ferner als Profilelement insbesondere mit einem I-förmigen oder L-förmigen Querschnitt oder als Leistenelement ausgebildet sein.The term coupling rod does not necessarily imply a cylindrical configuration of the coupling rod. In particular, the coupling rod can thus have a round, oval, rectangular, triangular or polygonal cross section. In particular, the coupling rod can also be designed as a profile element, in particular with an I-shaped or L-shaped cross section, or as a strip element.

Insbesondere kann das Reibelement von einem insbesondere elastischen Kunststoff teilweise oder gänzlich umhüllt sein und/oder einen Kunststoff als Bestandteil aufweisen oder vollständig aus Kunststoff bestehen. Dadurch kann einerseits das Rostrisiko minimiert und andererseits ein mögliches Quietschen zwischen der Kopfplatte und/oder dem Reibelement und/oder der Kopplungsstange verhindert werden.In particular, the friction element can be partially or completely encased by an in particular elastic plastic and/or have a plastic as a component or consist entirely of plastic. As a result, on the one hand, the risk of rusting can be minimized and, on the other hand, possible squeaking between the headstock and/or the friction element and/or the coupling rod can be prevented.

Vorzugsweise ist das Reibelement als Tellerfeder ausgebildet. Eine derartige Tellerfeder stellt einerseits eine ausreichende Stabilisierung der Lamellen durch ausreichende Dämpfung der Bewegung der Lamellen gegenüber der Kopplungsstange sicher. Andererseits ermöglicht eine derartige Tellerfeder eine nicht allzu stark gedämpfte Bewegung der Lamellen gegenüber der Kopplungsstange, sodass nicht viel Kraft zum Verschwenken der Lamellen aufgewendet werden muss. Ferner ermöglicht eine derartige Tellerfeder mögliche Toleranzen in der Geometrie der einzelnen Bauteile und/oder mögliche durch die Lebensdauer oder durch Witterungsbedingungen, insbesondere Temperaturschwankungen, bedingte Geometrieänderungen der Überdachung auszugleichen. Auf diese Weise wird ein fehlerfreier Betrieb der Überdachung ermöglicht.The friction element is preferably designed as a disc spring. Such a disc spring ensures, on the one hand, sufficient stabilization of the slats by sufficient damping of the movement of the slats relative to the coupling rod. On the other hand, such a plate spring allows a not too much dampened movement of the lamellae compared to the Coupling rod, so not much force is needed to pivot the slats. Furthermore, such a plate spring makes it possible to compensate for possible tolerances in the geometry of the individual components and/or possible changes in the geometry of the roofing caused by the service life or by weather conditions, in particular temperature fluctuations. This enables the canopy to operate correctly.

Insbesondere können mehrere Tellerfedern als Tellerfederpaket das Reibelement ausbilden. Die Tellerfeder oder das Tellerfederpaket kann dabei in einem Gehäuse, insbesondere aus Kunststoff, angeordnet sein.In particular, several plate springs can form the friction element as a set of plate springs. The cup spring or the set of cup springs can be arranged in a housing, in particular made of plastic.

In einer bevorzugten Ausführungsform ist das Reibelement um den Kopplungsstift herum angeordnet. Insbesondere kann dabei ein einzelnes als Scheibe, Halbscheibe oder Viertelscheibe ausgebildetes Reibelement angeordnet sein, welches den Außenumfang des Kopplungsstifts zumindest teilweise, insbesondere vollständig, umgibt. Alternativ oder kumulativ können mehrere Reibelemente angeordnet werden, welche um den Außenumfang des Kopplungsstifts herum, insbesondere gleichmäßig, verteilt sind.In a preferred embodiment, the friction element is arranged around the coupling pin. In particular, a single friction element designed as a disk, half disk or quarter disk can be arranged, which at least partially, in particular completely, surrounds the outer circumference of the coupling pin. Alternatively or cumulatively, several friction elements can be arranged, which are distributed, in particular evenly, around the outer circumference of the coupling pin.

Vorzugsweise ist das Reibelement als Druckfeder, insbesondere Schraubenfeder, ausgebildet. Dabei übt die Druckfeder eine Kraft parallel oder in einem spitzen Winkel, insbesondere von 1° bis 45°, zur Längserstreckung der Lamelle auf die Kopfplatte und/oder auf die Kopplungsstange aus und stabilisiert die beiden Teile gegenüber einander. Die Druckfeder kann dabei in einem Gehäuse, insbesondere aus Kunststoff, angeordnet sein.The friction element is preferably designed as a compression spring, in particular a helical spring. The compression spring exerts a force parallel to or at an acute angle, in particular from 1° to 45°, to the longitudinal extent of the lamella on the head plate and/or on the coupling rod and stabilizes the two parts relative to one another. The compression spring can be arranged in a housing, in particular made of plastic.

Eine derartige Druckfeder stellt einerseits eine ausreichende Stabilisierung der Lamellen durch ausreichende Dämpfung der Bewegung der Lamellen gegenüber der Kopplungsstange sicher. Andererseits ermöglicht die Druckfeder eine nicht allzu stark gedämpfte Bewegung der Lamellen gegenüber der Kopplungsstange, sodass nicht zu viel Kraft zum Verschwenken der Lamellen aufgewendet werden muss. Ferner ermöglicht die Druckfeder mögliche Toleranzen in der Geometrie der einzelnen Bauteile und/oder mögliche durch die Lebensdauer oder durch Witterungsbedingungen, insbesondere Temperaturschwankungen, bedingte Geometrieänderungen der Überdachung auszugleichen. Auf diese Weise wird ein fehlerfreier Betrieb der Überdachung ermöglicht.Such a compression spring ensures, on the one hand, sufficient stabilization of the slats by sufficient damping of the movement of the slats relative to the coupling rod. On the other hand, the compression spring allows the slats to move in relation to the coupling rod without being damped too much, so that too much force does not have to be used to pivot the slats. Furthermore, the compression spring allows possible tolerances in the geometry of the individual components and/or possible through the service life or through Weather conditions, in particular temperature fluctuations, to compensate for changes in the geometry of the roofing. This enables the canopy to operate correctly.

Dabei kann die Druckfeder alternativ oder kumulativ zu einer Tellerfeder oder einem Tellerfederpaket angeordnet sein. Insofern kann das Reibelement als Kombination aus einer Tellerfeder oder einem Tellerfederpaket und einer Druckfeder ausgeführt sein.The compression spring can be arranged alternatively or cumulatively to a plate spring or a set of plate springs. In this respect, the friction element can be designed as a combination of a plate spring or a set of plate springs and a compression spring.

In einer bevorzugten Ausführungsform ist zwischen dem Reibelement und der Kopfplatte und/oder zwischen dem Reibelement und der Kopplungsstange zumindest ein Dichtungselement angeordnet, insbesondere wobei das Dichtungselement einen Kunststoff als Bestandteil aufweist oder vollständig aus Kunststoff besteht. Dadurch wird ein Eindringen von Wasser zwischen dem Reibelement und der Kopfplatte und/oder zwischen dem Reibelement und der Kopplungsstange verhindert und somit das Rostrisiko minimiert. Ferner wird hierdurch ein mögliches Quietschen zwischen den genannten Bauteilen, insbesondere wenn die in Kontakt stehenden Bauteile aus Metall gefertigt sind, bei relativer Bewegung zueinander verhindert.In a preferred embodiment, at least one sealing element is arranged between the friction element and the head plate and/or between the friction element and the coupling rod, in particular the sealing element having a plastic as a component or consisting entirely of plastic. This prevents water from penetrating between the friction element and the headstock and/or between the friction element and the coupling rod, thus minimizing the risk of rusting. Furthermore, this prevents possible squeaking between the components mentioned, in particular when the components in contact are made of metal, when they move relative to one another.

Ein derartiges Dichtungselement kann bei Anordnung mehrerer Reibelemente ebenfalls zwischen den Reibelementen angeordnet werden. Insbesondere kann das Dichtungselement als Dichtungsscheibe ausgebildet sein. Insbesondere kann sich dabei um eine kunststoffummantelte und/oder gummiummantelte Unterlegscheibe handeln.Such a sealing element can also be arranged between the friction elements when a plurality of friction elements are arranged. In particular, the sealing element can be designed as a sealing disk. In particular, this can be a plastic-coated and/or rubber-coated washer.

Vorzugsweise weist die Kopplungsstange eine oder mehrere Bohrungen, insbesondere Durchgangsbohrungen auf, in welche der Kopplungsstift oder die Kopplungsstifte jeweils eingreifen.The coupling rod preferably has one or more bores, in particular through bores, in which the coupling pin or the coupling pins respectively engage.

In einer bevorzugten Ausführungsform weisen die Lamellen jeweils an ihrer ersten Seite und/oder an ihrer zweiten Seite zumindest einen Schwenkstift auf, mittels dessen die Lamellen jeweils um ihre Drehachse an den Trägern verschwenkbar gelagert sind.In a preferred embodiment, the slats each have on their first side and/or on their second side at least one pivot pin, by means of which the slats are each mounted on the carriers such that they can pivot about their axis of rotation.

Insbesondere können die beidseitigen Schwenkstifte der Lamelle von einem sich über die Längserstreckung der Lamelle und darüber hinaus erstreckenden Schwenkstift gebildet sein. Insbesondere kann die Drehachse der Lamelle mittels eines derartigen Schwenkstiftes gebildet sein.In particular, the pivot pins on both sides of the slat can be formed by a pivot pin extending over the longitudinal extent of the slat and beyond. In particular, the axis of rotation of the lamella can be formed by means of such a pivot pin.

Vorzugsweise weisen die Lamellen an ihrer zweiten Seite jeweils eine weitere Kopfplatte auf.Preferably, the slats each have a further top plate on their second side.

In einer bevorzugten Ausführungsform weisen die Lamellen an ihrer zweiten Seite jeweils eine weitere Kopfplatte auf, wobei die weiteren Kopfplatten der Lamellen jeweils über einen weiteren Kopplungsstift schwenkbar an einer weiteren Kopplungsstange gekoppelt sind.In a preferred embodiment, the slats each have a further head plate on their second side, the further head plates of the slats being pivotably coupled to a further coupling rod via a further coupling pin.

Vorzugsweise ist dabei zwischen der weiteren Kopplungsstange und zumindest einer der weiteren Kopfplatten, insbesondere jeder weiteren Kopfplatte, zumindest ein Reibelement angeordnet ist, welches mittelbar oder unmittelbar in Kontakt mit der weiteren Kopplungsstange und/oder mit der weiteren Kopfplatte steht. Dadurch werden die Lamellen beidseitig stabilisiert.Preferably, at least one friction element is arranged between the additional coupling rod and at least one of the additional head plates, in particular each additional head plate, which is directly or indirectly in contact with the additional coupling rod and/or with the additional head plate. This stabilizes the slats on both sides.

Bevorzugt weist die Überdachung zumindest einen insbesondere senkrechten Pfosten auf, der zumindest einen der Träger stützt. Dabei kann einer der Träger an einem Gebäudesturz montiert sein, während der andere Träger von dem zumindest einen Pfosten gestützt werden kann. Insbesondere kann jeweils ein Träger von zumindest einem, insbesondere von zwei Pfosten gestützt werden.The canopy preferably has at least one, in particular vertical, post which supports at least one of the beams. In this case, one of the carriers can be mounted on a building lintel, while the other carrier can be supported by the at least one post. In particular, a carrier can be supported by at least one, in particular by two, posts.

Vorzugsweise weist die Überdachung einen aus mehreren Trägern gebildeten Rahmen auf. Insbesondere kann der Rahmen von mehreren, insbesondere vier an den Ecken des Rahmens angeordneten Pfosten getragen werden. Alternativ oder kumulativ kann der Rahmen an einem oder mehreren Gebäudewänden montiert sein. Ferner können mehrere Lamellendächer in Form einer Reihenanordnung angeordnet sein und insbesondere jeweils von mehreren Pfosten getragen werden und/oder an einem oder mehreren Gebäudewänden montiert sein.Preferably, the canopy has a frame formed from a plurality of beams. In particular, the frame can be supported by a plurality of, in particular four, posts arranged at the corners of the frame. Alternatively or cumulatively, the frame can be mounted on one or more building walls. Furthermore, several slat roofs can be arranged in the form of a row arrangement and in particular each can be carried by several posts and/or can be mounted on one or more building walls.

Die Figur 1 zeigt eine perspektivische Ansicht einer erfindungsgemäßen Überdachung 100 in Form eines Lamellendaches. Die Begriffe Überdachung 100 und Lamellendach werden synonym benutzt. Die Überdachung 100 weist vier Träger 1, 2, 3, 4 auf, welche einen Rahmen der Überdachung 100 bilden. An den Trägern 1 und 2 sind mehrere Lamellen 10, 20, 30 verschwenkbar gelagert.The figure 1 shows a perspective view of a canopy 100 according to the invention in the form of a slat roof. The terms canopy 100 and slat roof are used synonymously. The canopy 100 has four beams 1, 2, 3, 4, which form a frame of the canopy 100. On the carriers 1 and 2, a plurality of slats 10, 20, 30 are pivotably mounted.

Die Lamellen 10, 20, 30 sind dabei um 90° gegenüber der Schließstellung der Lamellen 10, 20, 30 in Richtung der Öffnungsstellung der Lamellen 10, 20, 30 verschwenkt.The slats 10, 20, 30 are pivoted through 90° relative to the closed position of the slats 10, 20, 30 in the direction of the open position of the slats 10, 20, 30.

Die Lamellen 10, 20, 30 sind dabei mittels einer Kopplungsstange 9 kinematisch miteinander gekoppelt, um deren Verschwenken zu synchronisieren.The slats 10, 20, 30 are kinematically coupled to one another by means of a coupling rod 9 in order to synchronize their pivoting.

Mittels eines nicht dargestellten Antriebs, welcher mittels einer ebenfalls nicht dargestellten Steuereinheit angesteuert wird, können die Lamellen 10, 20, 30 verschwenkt werden. Hierzu nimmt die entsprechend geometrisch gestaltete erste Lamelle 10 einen Rohrmotor auf, mittels dessen die erste Lamelle 10 angetrieben und verschwenkbar ist. Durch die kinematische Kopplung der ersten Lamelle 10 über die Kopplungsstange 9 mit den weiteren Lamellen 20, 30 werden sämtliche Lamellen 10, 20, 30 synchron verschwenkt.The slats 10, 20, 30 can be pivoted by means of a drive, not shown, which is controlled by means of a control unit, also not shown. For this purpose, the correspondingly geometrically designed first slat 10 accommodates a tubular motor, by means of which the first slat 10 is driven and pivotable. Due to the kinematic coupling of the first slat 10 via the coupling rod 9 with the other slats 20, 30, all the slats 10, 20, 30 are pivoted synchronously.

Die Träger 1, 2, 3, 4 werden von senkrechten Pfosten 5, 6, 7 und einem weiteren in der Perspektive gemäß Fig. 1 nicht sichtbaren Pfosten an den Ecken zwischen den Trägern 1, 2, 3, 4 getragen. In Figur 1 ist die Druckfederanordnung zwischen Träger 1 und der Kopplungsstange nicht dargestellt. Diese wird nachfolgend erläutert.The beams 1, 2, 3, 4 are supported by vertical posts 5, 6, 7 and one more in perspective 1 not visible posts at the corners between the beams 1, 2, 3, 4 worn. In figure 1 the compression spring arrangement between carrier 1 and the coupling rod is not shown. This is explained below.

Die Figuren 2 bis 5 zeigen vergrößerte Ansichten der Druckfeder 50 zwischen dem Träger 1 der Überdachung 100 und der Kopplungsstange 9 in verschiedenen Perspektiven.The Figures 2 to 5 show enlarged views of the compression spring 50 between the support 1 of the canopy 100 and the coupling rod 9 in different perspectives.

Figur 6 zeigt eine vergrößerte perspektivische Ansicht des Befestigungspunktes des losen Endes 52 der Druckfeder 50 an der Kopplungsstange 9. figure 6 shows an enlarged perspective view of the attachment point of the loose end 52 of the compression spring 50 to the coupling rod 9.

Figur 7 zeigt eine vergrößerte perspektivische Ansicht des Befestigungspunktes des festen Endes 51 der Druckfeder 50 an dem Träger 1 der Überdachung 100. figure 7 shows an enlarged perspective view of the attachment point of the fixed end 51 of the compression spring 50 to the beam 1 of the canopy 100.

Die Anordnung der Druckfeder 50 wird nachfolgend anhand der Figuren 2 bis 7 erläutert.The arrangement of the compression spring 50 is based on the Figures 2 to 7 explained.

Es ist eine Druckfeder 50 in Form einer Gasdruckfeder zwischen dem Träger 1 des Lamellendaches 100 und der Kopplungsstange 9 angeordnet. Die Kolbenstange der Gasdruckfeder 50 ist von einer Schutzummantelung 53 umgeben. Dies Schutzummantelung 53 dient dem Schutz der Gasdruckfeder 50 und insbesondere der Kolbenstange der Gasdruckfeder 50 gegen Verschmutzungen und Umwelteinflüsse. Die Schutzummantelung 53 weist am unteren Ende Wasserablaufbohrungen 530 auf, um in die Schutzummantelung 53 eintretendes Regenwasser ableiten zu können. Hierdurch wird stehendes Wasser innerhalb der Schutzummantelung 53 vermieden.A compression spring 50 in the form of a gas pressure spring is arranged between the carrier 1 of the slatted roof 100 and the coupling rod 9 . The piston rod of the gas pressure spring 50 is surrounded by a protective casing 53 . This protective casing 53 serves to protect the gas pressure spring 50 and in particular the piston rod of the gas pressure spring 50 against dirt and environmental influences. The protective casing 53 has water drainage holes 530 at the lower end in order to be able to drain off rainwater entering the protective casing 53 . In this way standing water within the protective casing 53 is avoided.

Das feste Ende 51 der Druckfeder 50 ist mittels eines Winkels 511 und einer das Auge 510 der Druckfeder 50 am festen Ende 51 durchgreifenden Schraubverbindung 512 am Träger 1 befestigt. Das feste Ende 51 der Druckfeder 50 ist somit ortsfest festgelegt. Der Schraubenbolzen der Schraubverbindung 512 und das Auge 510 der Druckfeder 50 am festen Ende 51 bilden eine Spielpassung.The fixed end 51 of the compression spring 50 is fastened to the carrier 1 by means of an angle bracket 511 and a screw connection 512 that passes through the eye 510 of the compression spring 50 at the fixed end 51 . The fixed end 51 of the compression spring 50 is thus fixed in place. The screw bolt of the screw connection 512 and the eye 510 of the compression spring 50 at the fixed end 51 form a loose fit.

Das lose Ende 52 der Druckfeder 50 ist mittels eines Winkels 521 und einer das Auge 520 der Druckfeder 50 am losen Ende 52 durchgreifenden Schraubverbindung 522 an der Kopplungsstange 9 befestigt. Das lose Ende 52 der Druckfeder 50 ist somit zusammen mit der Kopplungsstange 9 beweglich.The loose end 52 of the compression spring 50 is fastened to the coupling rod 9 by means of an angle bracket 521 and a screw connection 522 that passes through the eye 520 of the compression spring 50 at the loose end 52 . The loose end 52 of the compression spring 50 can thus be moved together with the coupling rod 9 .

Der Schraubenbolzen der Schraubverbindung 522 und das Auge 520 der Druckfeder 50 am losen Ende 52 bilden eine Spielpassung.The bolt of the screw connection 522 and the eye 520 of the compression spring 50 at the loose end 52 form a loose fit.

Bei dem dargestellten Ausführungsbeispiel ist das feste Ende 51 der Druckfeder 50 unabhängig von der aktuellen Positionierung des losen Endes 52 der Druckfeder 50 stets geodätisch unterhalb des losen Endes 52 der Druckfeder 50 angeordnet. Alternativ kann bei einem nicht dargestellten Ausführungsbeispiel das feste Ende 51 der Druckfeder 50 unabhängig von der aktuellen Positionierung des losen Endes 52 der Druckfeder 50 stets geodätisch oberhalb des losen Endes 52 der Druckfeder 50 angeordnet sein. Wichtig ist dabei nur, dass die Anordnung der Druckfeder 50 es gewährleistet, dass unabhängig von der aktuellen Positionierung des losen Endes 52 der Druckfeder 50 stets eine Druckkraft in Schließrichtung der Lamellen 10, 20, 30 auf die Kopplungsstange 9 und/oder die Lamellen 10, 20, 30 ausgeübt wird.In the illustrated embodiment, the fixed end 51 of the compression spring 50 is always located geodetically below the loose end 52 of the compression spring 50 regardless of the current positioning of the loose end 52 of the compression spring 50 . Alternatively, in an exemplary embodiment that is not shown, the fixed end 51 of the compression spring 50 can always be arranged geodetically above the loose end 52 of the compression spring 50 regardless of the current positioning of the loose end 52 of the compression spring 50 . It is only important that the arrangement of the compression spring 50 ensures that, regardless of the current positioning of the loose end 52 of the compression spring 50, there is always a compressive force in the closing direction of the slats 10, 20, 30 on the coupling rod 9 and/or the slats 10, 20, 30 is exercised.

Zur Öffnung des Lamellendaches 100 werden die Lamellen 10, 20 ,30 aus der Schließstellung, wie sie in den Figuren 2 bis 5 dargestellt ist, synchron in eine Öffnungsstellung verschwenkt. Dies wird unter Bezugnahme auf Figur 5 erläutert. Zum Öffnen des Lamellendaches 100 werden die Lamellen 10, 20, 30 mittels des elektrischen Antriebs aus der in Figur 5 dargestellten Schließstellung, in der die Lamellen 10, 20, 30 eine geschlossene, regendichte Dachfläche bilden, gegen den Uhrzeigersinn in eine Öffnungsstellung verschwenkt. Durch die kinematische Kopplung der Lamellen 10, 20, 30 über die Kopplungsstange 9 erfolgt ein synchrones Verschwenken der Lamellen 10, 20, 30. Das lose Ende 52 der Druckfeder 50 wird zusammen mit der Kopplungsstange 9 entlang des Pfeiles 55, der beim Verschwenken in die Öffnungsstellung einen Kreisbogen gegen den Uhrzeigersinn beschreibt, verfahren. Aufgrund der Anlenkung des Druckfeder 50 am festen Ende 51 am Träger 1 übt die Druckfeder 50 stets eine Druckkraft in Schließrichtung der Lamellen 10, 20, 30 auf die Kopplungsstange 9 und hierüber gleichzeitig auf die Lamellen 10, 20, 30 aus.To open the slatted roof 100, the slats 10, 20, 30 from the closed position, as in the Figures 2 to 5 is shown, synchronously pivoted into an open position. This is with reference to figure 5 explained. To open the slatted roof 100, the slats 10, 20, 30 are opened by means of the electric drive from the figure 5 illustrated closed position, in which the slats 10, 20, 30 form a closed, rainproof roof surface, pivoted counterclockwise into an open position. The kinematic coupling of the slats 10, 20, 30 via the coupling rod 9 causes the slats 10, 20, 30 to pivot synchronously opening position describes an arc of a circle counterclockwise. Due to the articulation of the compression spring 50 at the fixed end 51 on the carrier 1, the compression spring 50 always exerts a compressive force in the closing direction of the slats 10, 20, 30 on the coupling rod 9 and here simultaneously on the slats 10, 20, 30.

Dabei ist die Druckfeder 50 derart angeordnet, sodass auch in der geschlossenen Position der Lamellen 10, 20, 30 eine Druckkraft in Schließrichtung der Lamellen 10, 20, 30 auf die Kopplungsstange 9 ausgeübt wird. Hierdurch wird ein ungewolltes Spiel und damit verbundenes Klappern der Lamellen 10, 20, 30 insbesondere in der Schließstellung der Lamellen auch bei abgeschaltetem elektrischem Antrieb verhindert und die Dachfläche wird in der Schließstellung der Lamellen 10, 20, 30 zuverlässig regendicht abgedichtet.The compression spring 50 is arranged in such a way that even when the slats 10 , 20 , 30 are in the closed position, a compressive force is exerted on the coupling rod 9 in the closing direction of the slats 10 , 20 , 30 . This will create a unwanted play and the associated rattling of the slats 10, 20, 30, especially when the slats are in the closed position, is prevented even when the electric drive is switched off, and the roof surface is reliably sealed against rain when the slats 10, 20, 30 are in the closed position.

Im Fall eines Ausfalls des elektrischen Antriebs kann der Benutzer manuell eine Notentriegelung des elektrischen Antriebs betätigen und hierdurch den elektrischen Antrieb von den Lamellen 10, 20, 30 entkoppeln. Durch diese Entkopplung des elektrischen Antriebs von dem Lamellen 10, 20, 30 laufen die Lamellen 10, 20, 30 frei. Aufgrund der stets durch die Druckfeder 50 aufgeprägte Druckkraft auf die Kopplungsstange 9 und damit auf die Lamellen 10, 20, 30 in Schließrichtung schließt das Lamellendach 100 nach Betätigung der Notentriegelung des elektrischen Antriebs durch den Benutzer automatisch die Lamellen 10, 20, 30. Das Auslösen der Notentriegelung des elektrischen Antriebsmotors führt somit aufgrund der Druckfeder 50 zu einem automatischen Schließen den Lamellendaches 100.In the event of a failure of the electric drive, the user can manually actuate an emergency release of the electric drive and thereby decouple the electric drive from the slats 10, 20, 30. Due to this decoupling of the electric drive from the slats 10, 20, 30, the slats 10, 20, 30 run freely. Due to the pressure force exerted by the compression spring 50 on the coupling rod 9 and thus on the slats 10, 20, 30 in the closing direction, the slatted roof 100 automatically closes the slats 10, 20, 30 after the user has activated the emergency release of the electric drive. The triggering the emergency release of the electric drive motor thus leads to an automatic closing of the slatted roof 100 due to the compression spring 50.

Die Figur 8 zeigt die erste vergrößerte Ansicht eines Ausschnitts der Lamelle 10 mit der Kopplungsstange 9 der Überdachung 100 nach Figur 1 aus der Vogelperspektive, wobei sich die Lamelle 10 abweichend von Fig. 1 in der Schließstellung befindet. Die Lamelle 10 weist dabei eine nicht vollständig dargestellte Längserstreckung L und eine Kopfplatte 11 auf. Ferner weist die Lamelle 10 einen Schwenkstift 15 auf, welcher verschwenkbar an dem Träger 1 nach Figur 1 gelagert ist. Der Schwenkstift 15 bildet dabei die Drehachse der Lamelle 10.The figure 8 shows the first enlarged view of a section of the slat 10 with the coupling rod 9 of the canopy 100 figure 1 from a bird's eye view, with the lamella 10 deviating from 1 is in the closed position. The lamella 10 has a longitudinal extension L, which is not shown in full, and a top plate 11 . Furthermore, the lamella 10 has a pivot pin 15 which can be pivoted on the carrier 1 figure 1 is stored. The pivot pin 15 forms the axis of rotation of the slat 10.

Die Kopplungsstange 9 ist als Leisteneckelement ausgebildet. Ein Kopplungsstift 12, mittels dessen die Kopfplatte 11 mit der Kopplungsstange 9 gekoppelt ist, ist als Schraube ausgebildet. Der Kopplungsstift 12 durchgreift eine Durchgangsbohrung der Kopplungsstange 9 sowie eine Durchgangsbohrung der Kopfplatte 11 und wird mittels einer Mutter 13 gesichert.The coupling rod 9 is designed as a strip corner element. A coupling pin 12, by means of which the head plate 11 is coupled to the coupling rod 9, is designed as a screw. The coupling pin 12 passes through a through hole in the coupling rod 9 and a through hole in the top plate 11 and is secured by means of a nut 13 .

Zwischen der Kopfplatte 11 und der Kopplungsstange 9 ist ein in dem dargestellten Ausführungsbeispiel durch eine Tellerfeder gebildetes Reibelement 8 angeordnet. Das Reibelement 8 umgibt dabei den Kopplungsstift 12 und dämpft bzw. bremst die Bewegung der Kopfplatte 11 und der Kopplungsstange 9 gegeneinander. Auf diese Weise wird die Lamelle 10 an der Kopplungsstange 9 stabilisiert, sodass eine bspw. durch Wind verursachte unerwünschte Bewegung der Lamelle 10 verhindert wird.Between the head plate 11 and the coupling rod 9 is a friction element formed in the illustrated embodiment by a plate spring 8 arranged. The friction element 8 surrounds the coupling pin 12 and dampens or brakes the movement of the top plate 11 and the coupling rod 9 against each other. In this way, the slat 10 is stabilized on the coupling rod 9 so that an undesired movement of the slat 10 caused by wind, for example, is prevented.

Die Figur 9 zeigt die zweite vergrößerte Ansicht der Lamelle 10 mit der Kopplungsstange 9 nach Figur 2 aus einer seitlichen Perspektive von außen.The figure 9 12 shows the second enlarged view of the slat 10 with the coupling rod 9. FIG figure 2 from a side perspective from the outside.

Die Figur 10 zeigt die dritte vergrößerte Ansicht der Lamelle 10 mit der Kopplungsstange 9 nach Figur 2 in einer seitlichen Perspektive aus der Sicht über der Lamelle 10.The figure 10 12 shows the third enlarged view of the slat 10 with the coupling rod 9. FIG figure 2 in a side perspective from the view above the lamella 10.

Mittels des Reibelements 8 wird vermieden, dass sich beispielsweise bei stärkerem Wind die Lamelle 10 bzw. sämtliche Lamellen der Überdachung 100 bewegen und so ein Klappern erzeugen. Einerseits soll die Kopfplatte 11 möglichst stark mit der Kopplungsstange 9 gekoppelt sein. Andererseits soll dabei die Kopfplatte 11 möglichst einfach gegenüber der Kopplungsstange 9 bewegbar sein, um ein leichtes Verschwenken der Lamellen zu ermöglichen. Das Reibelement 8 stellt ein Gleichgewicht zwischen diesen beiden Anforderungen her und verbessert dadurch die Überdachung 100 insgesamt.The friction element 8 prevents the slat 10 or all slats of the roof 100 from moving, for example in strong winds, and thus causing rattling. On the one hand, the top plate 11 should be coupled to the coupling rod 9 as strongly as possible. On the other hand, the head plate 11 should be as easy as possible to move relative to the coupling rod 9 in order to allow easy pivoting of the slats. The friction element 8 strikes a balance between these two requirements, thereby improving the canopy 100 as a whole.
