Description

The invention relates to a canopy with at least two girders on which several lamellae are pivotably mounted about an axis of rotation, the axes of rotation of the lamellas running from one carrier to the other carrier, the lamellae from a closed position in which the lamellae form a closed roof surface , are pivotable, in particular, 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 limited by a first side and an opposite second side, a top plate being arranged on the first side and with the top plates of the slats are each pivotably coupled to the coupling rod via a coupling pin.

Such canopies are known. The disadvantage of known canopies is that the slats move, particularly in the open position, when there is particularly strong wind and thus cause rattling.

The object of the invention is to overcome the disadvantages of known canopies, in particular to 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 further developments of the invention are specified in the subclaims.

Particularly advantageous in the case of roofing with at least two beams, on which several lamellae are pivotably mounted about an axis of rotation, the axes of rotation of the lamellae running from one carrier to the other carrier, the lamellae from a closed position in which the lamellae form a closed roof surface , are pivotable, in particular, 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 limited by a first side and an opposite second side, a top plate being arranged on the first side and with the top plates of the lamellas are each pivotably coupled to the coupling rod via a coupling pin, it is that between the coupling rod and at least one of the head plates, in particular each head plate, at least one friction element is arranged, which is indirectly or centrally lbar is in contact with the coupling rod and / or with the head plate.

The opening of the roof or the slats is understood to be synonymous with pivoting the slats into an open position. The arbitrary opening position of the slats means a position deviating from the closed position by turning through any angle out of the closed position, in particular up to 360 °.

The coupling rod serves the kinematically coupled, in particular synchronous, pivoting of the slats. The top plates of the slats are each pivotably 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 slats and the coupling rod move relative 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 head plate should be able to be moved as easily as possible with respect to the coupling rod in order to allow the slats to pivot easily.

According to the invention, the friction element creates a balance between these two requirements. The friction element between the head plate and the coupling rod acts as a friction brake, so that it brakes or damps a relative movement of the head plate with respect to the coupling rod. In this way, regardless of the position of the lamella, the head plate is better coupled to the coupling rod and consequently also to the other lamellae coupled to the coupling rod. The entirety of the slats and the coupling rod is thus stabilized. This effectively prevents the lamellas from rattling, since the wind would now have to set the totality of the lamellas in connection with the coupling rod in motion, while at the same time the mobility of the head plate relative to the coupling rod is dampened by the friction element, in order to cause a rattling. This is effectively prevented by the arrangement of the friction element according to the invention.

When a single friction element is arranged, the friction element is accordingly in direct or indirect contact with both the head plate and the coupling rod. The friction element is indirectly in contact with the head 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 head plate and / or the coupling rod. Accordingly, the friction element is in direct contact with the head plate and / or the coupling rod if no further intermediate elements are arranged between the friction element and the head plate and / or the coupling rod.

If several friction elements are arranged, one of the friction elements is accordingly 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 is in direct contact, so that overall there is a damping of the movement between the head plate and the coupling rod. The arrangement of further intermediate elements between the friction elements is also possible here.

The term coupling rod does not necessarily imply a cylindrical design 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 enveloped by a particularly elastic plastic and / or have a plastic as a component or consist entirely of plastic. In this way, on the one hand, the risk of rust can be minimized and, on the other hand, a possible squeaking between the head plate and / or the friction element and / or the coupling rod can be prevented.

The slats can be pivoted in particular by means of an electric and / or manual drive which engages at least one or more slats and / or 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 conjunction with a nut.

The axes of rotation of the lamellae run directly or indirectly from one carrier, directly or indirectly, to the other carrier, the actual longitudinal extension of the lamellae being able to be smaller than, equal to or greater than the distance between the carriers.

In this case, the top plate is firmly connected to the lamella, in particular non-positively and / or cohesively and / or positively.

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 several 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 slats can each have a continuous cross section. In particular, the lamellae can be arranged inclined relative to the horizontal with respect to their longitudinal extension. Such an inclination serves to discharge rainwater hitting the closed lamellar roof to one side of the roof.

In particular, the slats can each be mounted so as to be pivotable 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 run at an angle to one another, the longitudinal extent of the successive lamellae decreasing in accordance with the distance between the carriers.

The two carriers can each be mounted on one part of the building. Alternatively, one of the carriers can be mounted on a part of the building. In that case, the carrier can be supported on the other side by means of at least one, in particular vertical, post. Alternatively, the canopy can be mounted free-standing and supported by several, in particular vertical, posts.

The friction element is preferably designed as a plate spring. Such a disc spring ensures, on the one hand, adequate stabilization of the lamellae through sufficient damping of the movement of the lamellae with respect to the coupling rod. On the other hand, such a disc spring allows a movement of the lamellae that is not too strongly damped with respect to the Coupling rod, so that not much force has to be used to pivot the slats. Furthermore, such a disc spring enables possible tolerances in the geometry of the individual components and / or possible changes in geometry of the roofing caused by the service life or weather conditions, in particular temperature fluctuations, to be compensated. In this way, error-free operation of the canopy is made possible.

In particular, several disc springs can form the friction element as a disc spring package. The disc spring or the disc spring assembly 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 in the form of 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 extension 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, adequate stabilization of the lamellae through sufficient damping of the movement of the lamellae with respect to the coupling rod. On the other hand, the compression spring enables a movement of the lamellae with respect to the coupling rod that is not too strongly damped, so that too much force does not have to be used to pivot the lamellae. Furthermore, the compression spring enables 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 Compensate for changes in the geometry of the roof. In this way, error-free operation of the canopy is made possible.

The compression spring can be arranged as an alternative or in addition to a disk spring or a disk spring assembly. In this respect, the friction element can be designed as a combination of a plate spring or a plate spring package 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 wherein the sealing element has a plastic as a component or consists entirely of plastic. This prevents water from penetrating between the friction element and the head plate and / or between the friction element and the coupling rod and thus minimizes the risk of rust. Furthermore, this prevents any possible squeaking between the named components, in particular if 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, it can be a plastic-coated and / or rubber-coated washer.

The coupling rod preferably has one or more bores, in particular through bores, into which the coupling pin or the coupling pins each engage.

In a preferred embodiment, the lamellae each have at least one pivot pin on their first side and / or on their second side, by means of which the lamellae are mounted on the supports so as to be pivotable about their axis of rotation.

In particular, the pivot pins on both sides of the lamella can be formed by a pivot pin extending over the longitudinal extent of the lamella and beyond. In particular, the axis of rotation of the lamella can be formed by means of such a pivot pin.

The lamellas preferably each have a further head plate on their second side.

In a preferred embodiment, the slats each have a further head plate on their second side, 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 further coupling rod and at least one of the further head plates, in particular every further head plate, which is in direct or indirect contact with the further coupling rod and / or with the further head plate. This stabilizes the slats on both sides.

The canopy preferably has at least one electric drive for pivoting the slats, which drive engages at least one or more slats and / or the coupling rod.

In particular, the roof itself can have a control unit and / or can 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, in particular vertical, post which supports at least one of the supports. 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 two, posts.

The canopy preferably has a frame formed from a plurality of carriers. In particular, the frame can be supported by several, 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 shown 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 lamella roof. The canopy 100 has four supports 1, 2, 3, 4, which form a frame of the canopy 100. A plurality of slats 10, 20, 30 are pivotably mounted on the carriers 1 and 2.

The slats 10, 20, 30 are pivoted by 90 ° with respect 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 another in perspective according to Fig. 1 non-visible posts at the corners between the beams 1, 2, 3, 4 carried.

The Figure 2 shows the first enlarged view of a section of the lamella 10 with the coupling rod 9 of the canopy 100 Figure 1 from the bird's eye view, the lamella 10 deviating from Fig. 1 is in the closed position. The lamella 10 has a longitudinal extension L (not shown in full) and a head plate 11. Furthermore, the lamella 10 has a pivot pin 15 which can pivot on the carrier 1 Figure 1 is stored. The pivot pin 15 forms the axis of rotation of the lamella 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 head plate 11 and is secured by means of a nut 13.

Between the head plate 11 and the coupling rod 9, a friction element 8, formed in the illustrated embodiment by a plate spring, is arranged. The friction element 8 surrounds the coupling pin 12 and dampens or brakes the movement of the head plate 11 and the coupling rod 9 relative to one another. In this way, the lamella 10 is stabilized on the coupling rod 9, so that undesired movement of the lamella 10 caused, for example, by wind, is prevented.

The Figure 3 shows the second enlarged view of the lamella 10 with the coupling rod 9 according to FIG Figure 2 from a lateral perspective from the outside.

The Figure 4 shows the third enlarged view of the lamella 10 with the coupling rod 9 according to FIG Figure 2 in a side perspective from the view above the lamella 10.

The friction element 8 prevents the slat 10 or all the slats of the roofing 100 from moving, for example in stronger winds, and thus generating a rattle. On the one hand, the head plate 11 should be coupled to the coupling rod 9 as strongly as possible. On the other hand, the head plate 11 should be able to be moved as easily as possible with respect to the coupling rod 9 in order to allow the slats to pivot easily. The friction element 8 balances these two requirements and thereby improves the canopy 100 as a whole.
