Description

The invention relates to a lamellar roof with a support structure which has at least two girders arranged at a distance from one another, and with a lamella arrangement made up of several lamellas arranged next to one another and / or parallel to one another, each extending between the girders, each pivotably mounted about a longitudinal axis and between a closed position, in which adjacent slats partially overlap, and an open position, in which a space is formed between adjacent slats, an actuating device, by means of which an adjustment movement can be applied to the slats, and a water channel are provided, which Extends in the longitudinal direction of one of the carriers, is held on the carrier and can be supplied with water that is located or accumulates on the upper side of the slats in their closed position, the water channel being designed as a channel-shaped profile that is open upwards in the direction of the slats t.

Such a lamellar roof is often used in a garden to protect a space under the lamellar roof, for example a terrace, from the weather to protect or let the sun shine on them. When the slats are in their open position, sunlight can pass between the slats and shine and illuminate the space below.

When the slats are in their closed position, however, they form a waterproof and usually also light-tight cover, so that the space under the slat roof is not only shaded but also protected from rain. When the slats are in their closed position and it rains, the rainwater collects on the tops of the slats. Usually a channel is provided in each lamella which runs in its longitudinal direction and in which the rainwater flows off to one of the end faces of the lamellae. One of the supports is arranged on each of the end faces next to the slats, the actuating device with which the slats can be adjusted is also mounted on at least one of the supports. If the carrier is arranged directly in front of the end faces of the slats, the rainwater located on the upper side of the slats flows through a gap which is arranged between the end face of the slats and the carrier. In order to prevent this water from dripping onto the space arranged below the lamellar roof, a water channel must be arranged below the carrier, which catches and drains off the rainwater. The distance between the water channel and the slats must be so large that they have enough space to move between their closed position and their open position. The space required by the slats is called the adjustment space. In this configuration, the water channel is operated by a person who is below the lamellar roof sits, clearly perceptible, which is perceived as unattractive in terms of design and aesthetics. Furthermore, there is the problem that, due to the distance between the lamella and the water channel, splash water and / or water can enter in the event of lateral driving rain.

From the DE 34 12 770 A1 a lamellar roof with the structure mentioned is known in which a channel forming a water channel is firmly attached to a carrier and protrudes laterally from this. A guide plate is assigned to the water channel, which can be moved under the face of the slats and thus catches the water draining off the slats and guides it to the water channel. To adjust the slats, the guide plate can be retracted so that the adjustment space required for adjusting the slats is free. Here, too, there is the problem that both the water channel and the guide plate and its adjusting device require a large installation space and are clearly visible. Furthermore, there is the problem that the adjusting device of the guide plate is exposed and is therefore exposed to the effects of the weather and also to the water running off the lamellas, whereby there is a risk of damage due to rust or contamination.

It is known to provide the slat on the end face at which the rainwater is to be drained off with a guide element that engages over the carrier and thus releases the rainwater on the slat over the carrier into a water channel that is located on the the side of the carrier facing away from the lamella is located. The disadvantage of this embodiment, however, is that the lamellae require a special structural design, which is complex and expensive. In addition, due to the water channel attached to the side, the carrier has a relatively large width, which is aesthetically unattractive.

The invention is based on the object of creating a lamella roof of the type mentioned, in which the water channel is integrated in a compact manner.

According to the invention, this object is achieved by a lamella roof with the features of claim 1. It is provided that the water channel as a whole is adjustable relative to the carrier between a functional position in which it is arranged below the end face of the slats facing the carrier and a rest position in which it is laterally adjustable relative to the end faces of the slats in the direction of the carrier is arranged offset and at least partially received in a channel-shaped pocket of the carrier. According to the invention, the basic idea is to adjust the water channel as a whole between different positions and, in particular, to move it. As long as the louvred roof is open, the water channel is usually not required, since the user does not bring the louvres into the open position when it is raining. If the slats are in the open position when it rains, the rainwater runs directly through the spaces between the slats to the space below the slat roof without rainwater accumulating which would have to be drained off through the water channel.

If, on the other hand, the slats are in their closed position, it must be ensured that the rainwater that collects on the top of the slats is drained off. For this purpose, the water channel is moved into its functional position in which it is arranged directly below the gap which is formed between the end faces of the lamellae and the carrier. The rainwater on the upper side of the slats flows through the gap and falls directly into the water channel below, which can be designed as a channel-shaped profile and in particular a U-profile open upwards in the direction of the slats. When the slats are to be brought into their open position, the water channel is moved to its rest position.

According to the invention it is provided that the water channel in its rest position is at least partially and preferably completely received in a channel-shaped pocket of the carrier. On the one hand, this has the advantage that the water channel is largely protected from external influences in its rest position; on the other hand, it has a very compact structure. The pocket can be designed as a profile that opens in the direction of the slats and thus laterally, in particular as a C-profile.

The channel-shaped pocket of the carrier is preferably so large that the water channel is completely received in the pocket in its position when it is retracted into the pocket and is thereby protected. The opening of the pocket through which the water channel is inserted into the pocket can be completely filled and covered by the water channel when the water channel is drawn into the pocket. In this way it is reliably prevented that contamination enter the water channel as long as it is in the pocket.

In a preferred embodiment of the invention it is provided that the water channel is biased into its functional position by means of a tensioning device, for example in the form of one or more springs. When the water channel is moved from its functional position to its rest position, i.e. when the water channel is pushed into the channel-shaped pocket of the carrier, the movement takes place against the force of the clamping device, which is thereby tensioned. The water channel is preferably held mechanically in its rest position inside the pocket with the aid of stops or locking elements. In order to bring the water channel from its rest position into the functional position and to push it out of the carrier's pocket, it is only necessary to cancel the action of the stops or locking elements, whereby the water channel is moved into its functional position as a result of the force of the clamping device.

In a preferred embodiment of the invention it is provided that the movement of the slats between the open position and the closed position and the movement of the water channel between the rest position and the functional position are coordinated with one another. When the slats are in their closed position, the water channel is arranged in its functional position and can absorb and discharge the water flowing off from the top of the slats. If the user wants to bring the slats into their open position and the actuating device required for this is activated manually or by a motor, this is ensured in a mechanical and / or electronic manner, preferably first the water channel is adjusted to its rest position before the adjustment movement of the slats begins in the open position. This ensures that the movements take place in such a way that they do not interfere with one another. In particular, it can be provided that the adjustment movement of the water channel into the rest position is first completed before the adjustment movement of the slats into the open position begins.

When the slats are moved from the open position to the closed position and the water channel is moved from the rest position to the functional position, the processes are correspondingly reversed.

In a preferred embodiment of the invention it is provided that the water channel is in its functional position within an adjustment space of the slats and in its rest position outside the adjustment space of the slats. Usually, the adjustment space of the slats must be kept free of other components so that they do not hinder the adjustment of the slats. If, however, the adjustment movements of the water channel on the one hand and the adjustment movements of the slats on the other hand take place one after the other, the water channel can be in its functional position directly below the gap forming between the slats and the carrier, whereby a particularly compact design is achieved.

In a preferred embodiment of the invention it is provided that the water channel can be displaced perpendicular to the longitudinal direction of the carrier, preferably in pure translation. At the same time, the adjustment movement should run in the longitudinal direction of the slats.

In a preferred embodiment of the invention it is provided that the adjusting movement of the water channel can be generated by means of the actuating device of the slats. A single actuating device can thus be provided which causes both the adjustment movement of the water channel and the adjustment movement of the slats, which ensures that the adjustment movements are always carried out in exactly the same time sequence.

In a possible embodiment of the invention it can be provided that the confirmation device of the lamellae has an in particular displaceable actuating part which can have a control cam for each lamella, into which an engagement part arranged on the end face of each lamella engages. When the actuating part is adjusted or shifted, all slats are thereby pivoted simultaneously and in a synchronized manner. This actuating part can additionally be provided with one or more control cams, each control cam being able to be brought into contact with a stop part of the water channel. When the actuating part is displaced, the control cam of the actuating part comes into contact with the stop part of the water channel and moves it into its rest position. The actuating part preferably extends in the longitudinal direction of the carrier and is also adjusted in this direction, the adjusting movement of the actuating part being converted via the control cam into an adjusting movement of the water channel running perpendicular to the longitudinal direction of the carrier. One or more wedge surfaces or inclined contact surfaces can be used for this implementation.

Figure 1 shows a possible embodiment of the basic structural design of a lamellar roof 10. In the embodiment shown, a support structure 11 consists of four vertical supports 22, which are supported with their lower end on a substrate and in their upper end Area carry a horizontal frame 23. On the frame 23, two supports 12, which run at a distance next to one another and parallel to one another and carry a lamella arrangement 13, are supported. The lamellar arrangement 13 comprises a multiplicity of parallel lamellas 14 arranged next to one another or one behind the other transversely to their longitudinal direction, each of which extends between the carriers 12 and is pivotably mounted on them. The slats 14 can be adjusted between a closed position in which adjacent slats 14 partially overlap and the slats 14 thus form a closed cover, and an open position in which the slats 14 are pivoted so that there is a gap between adjacent slats 14 or is formed.

In Figure 2 of the support structure 11, only one of the supports 12 is shown, which is designed as a partially closed profile and in its lower area has a longitudinally extending channel-shaped pocket 17 which opens in the direction of the lamellae 14 and is designed as a C-profile. An actuating device 15 for the lamellae 14 is provided in the interior of the closed profile section of the carrier 12. Each lamella is pivotably mounted on the support 12 on its end face in the usual manner. The actuating device 15 comprises a plate-shaped actuating part 19 which is arranged inside the carrier 12 and is displaceable in the longitudinal direction of the carrier 12. A control link 24 is assigned to each lamella 14 in the actuating part 19. Each lamella 14 has a bolt-shaped engagement part 25 which engages in one of the control links 24. When the actuating part 19 is displaced along the carrier 12, this linear thrust movement is via the control link 24 and the Engagement part 25 converted into a pivoting movement of the slats 14, so that the slats 14 between a closed position in which adjacent slats 14 partially overlap and in which a closed covering of the slat roof 10 is achieved (see FIG Figures 1 and 2 ), and an open position in which an intermediate space is formed between adjacent slats 14 and in which the slats are pivoted by approx. 90 ° with respect to the closed position (see FIG Figure 6 ).

In the channel-shaped pocket 17 of the carrier 12, a water channel 16 in the form of a rod-shaped profile is inserted. The water channel 16 is open on its upper side and, in the closed position of the slats 14, is arranged below a gap which is formed between the end faces of the slats 14 and the carrier 12. This represents the functional position of the water channel 16, as shown in FIG Figure 2 is shown. The water channel 16 is mounted displaceably perpendicular to the longitudinal direction L _{2 of} the carrier 12 and can be positioned between the in Figure 2 illustrated, above-explained functional position and a rest position completely retracted into the pocket 17 of the carrier 12 (see Figure 6 ) can be adjusted. To adjust the water channel 16, the actuating device 15 is used to adjust the slats 14, which are based on the Figure 3 is explained, in which some wall parts of the carrier 12 are omitted for the sake of clarity.

As Figure 3 shows, the actuating part 19 is fixedly provided in the region of each control link 24 with a projection 26 on which a control cam 20 designed as an inclined control curve is formed. Each approach 26 of the actuating part 19 is assigned to the water channel 16, a stop part 21, the one also has a control surface 27 designed as an inclined. When the actuating part 19 is _{displaced in the longitudinal direction L 2 of} the carrier 12, the control cam 20 of the projection 26 of the actuating part 19 comes into contact with the control surface 27 of the stop part 21 of the water channel 16. Due to the inclined design of the control curve 20 of the control surface 27, the linear adjustment of the actuating part 19 in the longitudinal direction L _{2 of} the carrier 12 leads to an adjustment of the water channel 16 running perpendicular thereto in the direction of the longitudinal axes L _{1 of} the slats 14.

As in Figure 3 is only indicated schematically, the water channel 16 is assigned a tensioning device 18 in the form of one or more springs 28. The tensioning device 18 or the springs 28 are aligned and designed in such a way that the water channel 16 is pretensioned by means of the tensioning device 18 into its functional position extended out of the pocket 17.

In the following, the Figures 2 to 6 it will be explained in individual phases how the water channel is adjusted between its functional position and its rest position and the slats 14 are adjusted between their closed position and their open position.

According to Figure 2 the slats 14 are in their closed position, in which they completely cover a space located below the slat roof. The water channel 16 is in its functional position extended from the pocket 17 in the lateral direction of the slats 14, in which it can catch the water that runs down or drips from the top of the slats 14 through the gap between the slats 14 and the carrier. if the slats 14 from their in Figure 2 are to be brought into their open position in the closed position shown, the rod-shaped actuating part 19 is _{displaced in the longitudinal direction L 2 of} the carrier 12. The cam 20 of the projection 26 of the actuating part 19 and the control surface 27 of the stop part 21 of the water channel 16 come into contact, so that the _{adjustment movement of the water channel 16 directed in the direction of the longitudinal axes L 1 of} the slats 14, with which it enters the pocket 17 of the Carrier 12 is inserted begins. The bolt-shaped engagement parts 25 of the lamellae 14 are still located in a section of the control link 24 running in the displacement direction of the actuating part 19, so that the lamellae 14 initially remain in their closed position. Figure 3 shows that the water channel 16 in relation to its functional position according to FIG Figure 2 is already displaced by a small amount, the tensioning device 18 or the spring 28 being tensioned during this displacement.

In Figure 4 the state shown is that the water channel 16 is in its rest position, in which it is arranged completely within the pocket 17, as shown in FIG Figure 6 can be seen. A wall of the water channel 16 facing the lamellae 14 is aligned with a corresponding wall of the carrier 12, so that a continuous side surface is provided.

When the rest position of the water channel 16 is reached, the control cam 20 of the projection 26 of the actuating part 19 and the control surface 27 of the stop part 21 of the water channel 16 disengage (see FIG Figure 4 ), so that a further movement of the actuating part 19 does not lead to a further adjustment of the water channel 16.

When the rest position of the water channel 16 is reached, the slats 14 are still in their closed position. When the actuating part 19 is displaced further, the bolt-shaped engagement parts 25 of the lamellae 14 enter a section of the control link 24 that is inclined upward, so that the lamellae 14 pivot as a result of the axial displacement of the actuating part 19. the Figures 5 and 6th show two phases of this adjustment, with the slats in Figure 6 are shown in their pivoted open position or shortly before reaching this open position.

In order to bring the slats 14 back into their closed position and the water channel 16 into its functional position, the actuating part is shifted in the opposite direction, whereby the slats 14 are initially pivoted back into their rest position in the manner shown. After the slats 14 have reached their rest position, the control cam 20 of the projection 26 of the actuating part 19 come into contact with the control surface 27 of the stop part 21 of the water channel 16, whereby the force of the clamping device 18 ensures that the water channel 16 can move the actuating part 19 follows and is moved laterally out of the pocket 17 of the carrier 11 in the direction of the slats 14 until it reaches its functional position according to FIG Figure 2 has reached.
