Description

The invention relates to a canopy with at least two 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, the slats moving from a closed position in which the slats form a closed roof surface , in particular can be pivoted into any open position, the slats being kinematically coupled to one another by means of at least one coupling rod, the slats each having a longitudinal extension delimited by a first side and an opposite second side, a top plate being arranged on the first side and wherein the top plates of the slats are each pivotally coupled to the coupling rod via a coupling pin.

Such canopies are out EP 2 803 778 A2 or EP 3 348 741 A1 famous. The disadvantage of known canopies is that the slats move in the open position, particularly in strong winds, and thus cause rattling.

The object of the invention is to overcome the disadvantages of known canopies, in particular to further develop a canopy in such a way that unwanted play and the associated rattling of the slats is prevented.

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.

Particularly advantageous in the case of the roofing with at least two 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, the slats moving from a closed position in which the slats form a closed roof surface , in particular can be pivoted into any open position, the slats being kinematically coupled to one another by means of at least one coupling rod, the slats each having a longitudinal extension delimited by a first side and an opposite second side, a top plate being arranged on the first side and wherein the top plates of the slats are each pivotally coupled to the coupling rod via a coupling pin, it is that between the coupling rod and at least one of the top plates, in particular each top plate, at least one friction element is arranged, which is directly or indirectly lbar is in contact with the coupling rod and/or with the headstock.

The opening of the roof or the slats is understood synonymously with pivoting the slats into an open position. Any open position of the slats means a position that deviates from the closed position by turning through any angle from the closed position, in particular up to 360°.

The coupling rod is used 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.

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.

According to the invention, the friction element strikes 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.

If 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 in contact with the top plate and/or the coupling rod if further intermediate elements, such as a seal and/or a washer, 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.

When several friction elements are arranged, one of the friction elements is in direct or indirect contact with the top plate, while another of the friction elements is in direct or indirect contact with the coupling rod is directly in contact, so that overall there is a damping of the movement between the headstock and the coupling rod. Here, too, the arrangement of further intermediate elements between the friction elements is possible.

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.

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.

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 coupling pin can be designed, for example, as a screw in connection with a nut.

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 extent of the slat being able to be less than or equal to or greater than the distance between the carriers.

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.

In particular, each lamella can be formed by a longitudinal profile, in particular a hollow profile. The longitudinal profile of each lamella 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.

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 lamellar roof to one side of the roofing.

In particular, the slats can each be pivoted about an axis of rotation running parallel to their longitudinal extension.

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.

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.

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 disc 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.

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 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.

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. 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 tolerances caused by the service life or by weather conditions, in particular temperature fluctuations to compensate for changes in the geometry of the roofing. This enables the canopy to operate correctly.

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 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.

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 washer. In particular, this can be a plastic-coated and/or rubber-coated washer.

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 a preferred embodiment, the slats each have at least one pivot pin on their first side and/or on their second side, by means of which the slats are each mounted on the supports such that they can pivot about their axis of rotation.

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.

Preferably, the slats each have a further top plate on their second side.

In a preferred embodiment, the slats each have a further head plate on their second side, with the further head plates of the slats each being pivotably coupled to a further coupling rod via a further coupling pin.

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.

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.

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.

The canopy preferably has at least one post, in particular a vertical post, which supports at least one of the beams. One of the carriers can be mounted on a building lintel, while the other carrier of the at least one post can be supported. In particular, a carrier can be supported by at least one, in particular by two, posts.

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 lintels.

The figures are not drawn to scale. Identical components are provided with identical reference symbols.

the figure 1 shows a perspective view of a canopy 100 according to the invention in the form of a slat roof. 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.

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.

The slats 10, 20, 30 are kinematically coupled to one another by means of a coupling rod 9 in order to synchronize their pivoting.

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.

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 Trägem 1, 2, 3, 4 worn.

the figure 2 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.

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 .

Between the head plate 11 and the coupling rod 9 is a friction element 8 formed by a plate spring in the illustrated embodiment. 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.

the figure 3 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.

the figure 4 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.

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.
