Description

[0001] The subject of the invention is a slat arrangement with a plurality of slats arranged parallel to one another with respect to their longitudinal extent and each slat can be pivoted synchronously about a pivot axis running in the direction of their longitudinal extent from a closed position to an open position and vice versa, which slats are each mounted in two slat supports opposite one another with respect to the slats, and with a drive device for adjusting the slats.

[0002] The slats of such a slat arrangement form a slat field when the slats are closed. Such a slat arrangement can be arranged horizontally, vertically, or at an angle with respect to the longitudinal extent of its slat supports, depending on the desired use or application of such a slat arrangement. With a horizontal arrangement of the slat supports, the individual slats of the slat arrangement are arranged horizontally next to one another. In this case, such a slat arrangement can form a slatted roof or be part of one. If the slat arrangement is designed as a slatted roof, the individual slats are typically arranged overlapping one another in the closed arrangement. In many cases, a rainproof seal is desired in such an application.The slats, arranged longitudinally between the two slat supports, can be pivoted synchronously between a closed position and an open position. This means that all slats in this slat arrangement pivot simultaneously. Such a slat arrangement is assigned a drive device with which the slats can be adjusted. In addition to manual drive devices, electric motor-driven drive devices are also common.

[0003] A slatted roof arrangement with an electric motor drive for adjusting the individual slats is known from DE 103 41 877 A1. This slatted roof has a drive rod that runs parallel to one of the two slat supports. An electric motor is connected to one end of the drive rod. The drive rod is translationally adjustable along its longitudinal axis. The individual slats are connected to this rod via a lifting device. To adjust the slats from their closed position to their open position, the drive rod is moved away from the electric motor by a distance along its longitudinal axis. A reverse translational adjustment movement of the rod pivots the slats into their closed position.In order to realize this louvre roof, a corresponding longitudinal extension in the direction of the longitudinal extension of the louvre supports is required so that the drive rod can be extended and retracted accordingly for the purpose of adjusting the louvres.

[0004] Another louvre roof is known from EP 4 435 198 A1. In this louvre roof, a tubular motor is used to adjust the louvres. The tubular motor is assigned to the first louvre in the row of louvres. All louvres have an adjusting lever assigned to one of their narrow sides, which carries a roller at one end and engages in a guide profile. The guide profile is part of a parallel link system, whereby this guide profile is adjustable in terms of its distance from a support profile, to which the guide rail is connected via two parallel links, and thus also in terms of its height relative to the louvres. A rotary movement of the first louvre is transmitted to the guide rail. In accordance with the raising or lowering movement of the guide rail, the other louvres are synchronously controlled to perform the same pivoting movement.

[0005] In conventional louvre roofs, the louvre roof is provided by such a louvre arrangement. Since the louvres extend across the entire width of such a louvre roof, only uniform shading or light penetration is possible across the entire width of the area spanned by the louvre roof. Furthermore, the drive units described above are considered complex.

[0006] Based on this discussed prior art, the invention is based on the object of developing a slat arrangement of the type described above in such a way that not only the drive of the adjustable slats is simplified, but they can also be easily combined with other similar slat arrangements.

[0007] This object is achieved according to the invention by a generic slat arrangement mentioned at the outset, in which the drive device comprises a drive shaft which is mounted in the slat carriers and arranged parallel to the longitudinal extent of the slats, on which drive shaft a torque transmission element is seated as a drive element in a torque-locking manner or which drives such a drive element, which torque transmission element acts on an actuator as an output element and the drive element acts directly or indirectly kinematically on the slats for the purpose of pivoting them, and the torque transmission element and / or the actuator are designed in such a way that torque is transmitted to the actuator in each direction of rotation of the drive shaft only over a specific angular segment which is less than 360°.

[0008] In this lamella arrangement, the drive shaft is arranged parallel to the longitudinal extent of the lamellas. A torque transmission element sits on this shaft as the drive element. The drive device of this lamella arrangement is also assigned an actuator. This represents the output element with respect to the torque transmission element. The actuator is mounted on a carrier, for example a lamella carrier. At least one lamella of this lamella arrangement is in turn connected to the actuator for the purpose of its pivoting. Typically, this lamella is the first lamella located adjacent to the drive shaft. From this lamella, the drive movement transmitted by the actuator is passed on to the other lamellas of this lamella arrangement, for example via adjusting links.Typically, the slat movable by the actuator for the purpose of its adjustment is indirectly connected to an adjustment movement of the actuator, namely via an adjusting lever, a link, or the like. A special feature of the drive device of this slat arrangement is that a rotation of the drive shaft of significantly less than 360° is sufficient to pivot the slats from their closed position to their open position and vice versa. Thus, the drive shaft of this slat arrangement only needs to be rotated by a small angular segment, which is typically significantly smaller than 360°, in order to pivot the slats over their full pivoting amount. The angular segment in which torque is transmitted from the torque transmission element to the actuator is preferably selected such that this angular segment is contained multiple times within one rotation of the drive shaft through 360°.A typical angle segment through which the drive shaft must be rotated to pivot the slats across their entire pivoting range is between 45° and 135°, in particular between 60° and 120°, and according to a preferred embodiment, 90° or approximately 90°. The drive shaft itself can be rotated through a larger angle segment. However, outside the angle segment intended for torque transmission, this has no influence on the adjustment of the slats.

[0009] A particular advantage of the drive device for this slat arrangement is that, due to the relatively small angular segment (360°) in which the actuator is controlled by the torque transmission element, structurally simple power transmission concepts that are otherwise unusual for torque transmission can be used to drive the actuator. A particular advantage, however, is that, due to transmission in a relatively small angular segment (e.g. 90°) in relation to 360°, the angular segments not used for actuating the slats of this slat arrangement can be used to actuate the slats of one or more further slat arrangements in an angular segment of a rotary actuation of the drive shaft in its angular segment of 360° that is different from the actuation of the slats of the first slat arrangement.This at least one further slat arrangement is preferably constructed in the same way as the first slat arrangement, in particular also with regard to the angular segment in which torque is transmitted to the actuator. However, a design is also possible in which, in a second slat arrangement, torque is transmitted in a different angular segment compared to the first slat arrangement. This allows the slats of slat arrangements arranged adjacent to a first slat arrangement to be controlled with one and the same drive. For example, if the slats of a first slat arrangement are moved from their closed position to their open position, the slats of the one or more further slat arrangements can remain closed.Only upon further actuation of the drive shaft over a second angular segment are the slats of the second slat arrangement adjacent to the first slat arrangement pivoted into their open position. Accordingly, the rotation transmission element and / or the actuator are designed for such an angular segment-limited angular segment that differs from the torque transmission in the adjacent slat arrangement within one revolution of the drive shaft. The special feature of this concept is that, despite controlling the slats of adjacent slat arrangements and independently actuating the slats of these slat arrangements, only a single drive is required. This drive is connected in a torque-locking manner to the drive shaft of a slat arrangement defining a slat field.The drive shafts of the further lamella arrangements are kinematically connected to the drive shaft of the first drive shaft, which is typically driven by the electric motor drive, for example in that the drive shafts of the lamella arrangements have a torque-locking coupling element as a rotary driving contour at one end thereof, for example implemented by an external rotary driving contour, and a complementary coupling element at their other end, for example an internal edge bushing.

[0010] The choice of the angular segment in which the slat adjustment of a slat array is carried out is determined by the number of slat arrays to be arranged next to each other, whereby the slats of individual slat arrays are to be actuated differently from each other. A typical example of the structure of a slat array is three slat arrays arranged next to each other. In this case, the angular segment for transmitting a rotary movement of the drive shaft to the actuator can typically be 80° to 100°, typically 90°.

[0011] For synchronous adjustment of the slats of such a slat arrangement, adjacent slats are kinematically coupled to one another, for example, by a link, a link chain, or the like, so that the slat adjacent to a first slat performs the same pivoting movement when the first slat is adjusted. It is also possible for the actuator to move an adjusting rod to which the individual slats of such a slat arrangement are articulated for the purpose of adjustment.

[0012] Regardless of the direction of rotation of the drive shaft, the angular segment in which the torque transmission element acts on the actuator is the same.

[0013] According to a first embodiment for transmitting a drive torque from the torque transmission element to the actuating element within a limited angular segment, the torque transmission element is designed as a cam disk. The geometry of the drive cam and, accordingly, its extension in the direction of rotation of the drive shaft is adapted to the angular segment in which slat adjustment is desired. The actuating element in such a design of the slat arrangement is, for example, an actuating lever. The cam disk acts on the actuating lever at a distance from the pivot axis of the actuating lever, particularly when torque is to be transmitted and thus the slats are to be pivoted. During torque transmission, the cam disk rolls with its outer surface on the actuating lever.According to one embodiment, a torque transmission to the adjusting lever is reset by one or more reset elements, for example return springs.

[0014] If several such slat arrangements are arranged next to one another to form a slat field and the slats of the individual slat arrangements are also to be in different positions, the cam disc used to adjust the individual slats of each slat arrangement is located with its cam at a different angular position on the drive shaft.

[0015] According to another embodiment of such a plate arrangement, a drive wheel mounted on the drive shaft serves as the torque transmission element, having at least one driver, typically parallel to its axis of rotation, typically in the form of a driver pin. In this exemplary embodiment, the actuator is designed as an adjusting wheel, which has at least one guide slot running in the radial direction and open towards the radial edge of the adjusting wheel. The outline of the adjusting wheel is adapted to the drive wheel mounted on the drive shaft, so that when the drive wheel rotates, a driver pin is guided into such a guide slot, and the adjusting wheel is accordingly driven by the rotation of the drive wheel and its movement in the guide slot. The driving of the adjusting wheel therefore only occurs in the angular segment in which the driver pin engages the guide slot.The interaction between the driver of the drive wheel and the guide slot of the adjusting wheel defines the angular segment of a rotational drive. In this configuration, the drive shaft is rotated in one direction by a maximum angle of rotation of less than 360°. With this configuration, the raised slats of the multiple slat arrangements can be reset to their closed position by operating the drive shaft in the opposite direction.

[0016] The arrangement of the driver(s) corresponding to the guide slot(s) of the adjusting wheel defines the rotational drive of the adjusting wheel in relation to the angle of rotation of the drive shaft.

[0017] If several such lamella arrangements are arranged next to one another to form a lamella field and the lamellae of the individual lamella arrangements are also to be in different positions, the drivers of the respective drive wheel of the individual lamella arrangements are located at different angular positions of the drive shaft.

[0018] Particularly good and smooth interaction between the drive wheel and the adjusting wheel is achieved in a design of such a lamella arrangement if the driving pin(s) of the drive wheel are arranged at a greater distance from the axis of rotation of the drive wheel than the radial edge of the other components of the drive wheel and if the outer side surfaces of the adjusting wheel bordering the opening of the guide slot are concavely curved with a radius of curvature that corresponds to the convex curvature of the drive wheel in the sections adjacent to the at least one driving pin. In this design, the drive wheel can be designed so that the adjusting wheel is supported by its outer surface, at least in sections, or is guided on the cylindrical outer surface of the drive wheel.To ensure free movement of the drive wheel and adjusting wheel, a further development provides for the drive wheel to have a recess extending radially toward each driving pin, extending in the direction of its longitudinal axis. During torque transmission, the opening area of ​​a guide slot passes through this recess.

[0019] In a preferred embodiment of such a slat arrangement with a drive wheel and an adjusting wheel as described above, it is expedient to equip the drive wheel with two driving pins arranged at an angular distance from one another. This allows a design of the slat arrangement such that, with several slat arrangements arranged next to one another, starting from a common closed position of the slats, the slats of the individual slat arrangements are pivoted one after the other into their open position when the drive shaft rotates in a first direction. However, when the drive shaft is actuated in the opposite direction, the slats of all slat arrangements are brought into their open position together.

[0020] The invention is described below using an exemplary embodiment with reference to the accompanying figures. They show: Fig. 1: A slatted roof comprising several slat arrangements according to the invention in a perspective view, Fig. 2: a perspective view of the drive units of the slat arrangements of the slat field of the Fig. 1, Fig. 3: a detailed representation of a torque transmission element sitting on a drive shaft as a drive element, which is engaged with an output element serving to control the slats, a side view, Fig. 4: the representation of the two elements of the Fig. 3 in a perspective view, Fig. 5a - 5c: the drive units of the slat arrangements, as in Fig. 2, showing the position of the individual slats in each slat arrangement after actuating the drive shaft by a first angular segment ( Fig. 5a), after actuating the drive shaft by a further angle segment ( Fig. 5b) and after operating the drive shaft by another angle segment ( Fig. 5c).

[0021] A louvre roof 1 of the illustrated embodiment, supported by four feet, has three louvre arrangements 2, 2.1, 2.2. The louvre arrangements 2, 2.1, 2.2 are essentially constructed in the same way. Therefore, the explanations given below for a louvre arrangement 2, 2.1, 2.2 apply equally to the other louvre arrangements, unless otherwise stated.

[0022] The slat arrangement 2 comprises a plurality of individual slats 3, which are arranged parallel to one another with respect to their longitudinal extent. The slats 3 are Fig. 1 shown closed position into an open position. The slats 3.2 of the slat arrangement 2.2, however, show the slats in their open position. The slat arrangement 2 has two parallel slat supports 4, 4.1. The slats 3 are pivotally mounted in or on these. The slat arrangement 2 also has a drive device 5, of which Fig. 5 only its housing 6 is visible.

[0023] In the Fig. In the enlarged view of the drive-side end sections of the slat arrangements 2, 2.1, 2.2 shown in Figure 2, the drive device 5 is shown without the housing 6. The drive device 5 of the slat arrangement 2 comprises a drive shaft 7. This is rotatably mounted in the slat carriers 4, 4.1. A torque transmission member 8 is seated on the drive shaft 7 as the drive element. In the illustrated embodiment, the torque transmission member is designed as a drive wheel and carries two driving pins 9, 9.1, wherein Fig. 2 only the driving pin 9 is visible. The driving pin 9.1 is concealed by the drive shaft 7. An actuator 10 designed as an adjusting wheel serves as the output element. The actuator 10 is adjustable about a pivot axis designated by the reference numeral 11. The pivot axis 11 runs parallel to the longitudinal axis of the drive shaft 7. A link 12 is connected to the actuator 10 and transmits the adjusting movement of the actuator 10 to the slat 3 of the slat arrangement 2 adjacent to the drive shaft 7. The other slats 3 of the slat arrangement 2 are each connected via a link to the adjusting movement of the slat 3 adjacent to the drive shaft 7, so that an adjustment of the slat 3 arranged adjacent to the drive shaft 7 leads to a synchronous adjustment of the other slats 3 of the slat arrangement 2.

[0024] Fig. 3 and Fig. 4 shows the torque transmission element 8 and the actuator 10 of the drive device 5 in a single view. This is a first position of the torque transmission element 8 to the actuator 10 in relation to a rotational position of the drive shaft 7. The arrangement between these two elements 8, 10 is shown, as in Fig. 2 shown. Fig. 4, however, shows the torque transmission element 8 and the actuator 10 in a position relative to each other after the drive shaft 7 has been rotated by an angular segment of 90°, as in Fig. 2 indicated by an arrow, has been adjusted.

[0025] The torque transmission element 8 has a shaft recess 13, which, like the drive shaft 7, is designed as a polygon for torque-locking connection. The torque transmission element 8 has a cylindrical base body 14 (see also Fig. 4). The torque transmission member 8 carries the two previously mentioned driving pins 9, 9.1, each of which is seated on a driving extension 17, 17.1 projecting beyond the outer edge 16 of the base body 14. The longitudinal axis of the driving pins 9, 9.1 extends parallel to the longitudinal axis of the drive shaft recess. Between each driving pin 9, 9.1 and the remaining components of the base body 14 there is a recess 18, 18.1 in each of which the thickness of the base body 14 is reduced by the length of one driving pin 9, 9.1. These recesses are delimited by a concavely curved wall section 19, 19.1 toward the center of the base body 14.

[0026] The actuator 10 is designed like an irregular adjusting wheel and has a number of guide slots 20, 20.1 corresponding to the number of driving pins 9, 9.1. The guide slots 20, 20.1 engage in the actuator 10 in the radial direction and thus in the direction of the pivot axis 11 of the actuator 10 and have a clear width such that one of the cylindrical driving pins 9, 9.1 can engage and be guided therein. The sides of the actuator 10, each enclosing an opening of a guide slot 20, 20.1 and facing outwards in the radial direction, are concavely curved, with a radius corresponding to that of the outer diameter of the base body 14 of the torque transmission element 8. Thus, they serve as a guide or support for the torque transmission element 8 or the torque transmission element 8 serves with its base body 14 to guide the actuator 10.A tab-like extension 21 is formed on the actuator 10, to the end of which the link 12 is connected in an articulated manner.

[0027] The drive units of the two other lamella assemblies 2.1, 2.2 are fundamentally identical in design. The drive shaft 7.1 of the lamella assembly 2.1 is connected to the drive shaft 7 in a torque-locking manner. For the torque-locking connection of two adjacent drive shafts 7, 7.1 or 7.1, 7.2, each drive shaft 7, 7.1, 7.2 carries at one end a rotary drive contour 22 designed as an inner contour, as can be seen on the drive shaft 7.2 of the lamella assembly 2.2. At the other end, each drive shaft 7, 7.1, 7.2 carries a complementary rotary drive pin that is inserted into the negative rotary drive contour of the adjacent drive shaft. This allows the three drive shafts 7, 7.1, 7.2 to be driven with a single drive device, for example an electric motor, connected to the drive shaft 7 or the drive shaft 7.2. Due to the juxtaposition of the slat arrangement 2, 2.1, 2.2, the torque-locked drive shafts 7, 7.1, 7.2 act as a single drive shaft. In the illustrated embodiment, three disk arrangements 2, 2.1, 2.2 are combined into a single unit. It is understood that only two or more than three disk arrangements can also be combined into a single unit in this way.

[0028] In the illustrated embodiment, the actuators 10.1, 10.2 of the two further slat arrangements 2.1, 2.2 are designed in the same way as the actuator 10. The same applies to the control of the slats 3.1, 3.2 of the respective slat arrangement 2.1 and 2.2. In the slat arrangement 2.2, a rotation transmission member 8.2 is located on the drive shaft 7.2, which is identical to the rotation transmission member 8 of the slat arrangement 2, whereby the latter is offset by one angular segment relative to the rotation transmission member 8 on its drive shaft 7.2, so that its driver pins extend over a different angular segment than the driver pins 9, 9.1 of the torque transmission member 8. In the illustrated embodiment, this angular segment offset is 90°.

[0029] The torque transmission element 8.1 of the middle disk arrangement 2.1 also carries two driving pins, which are arranged diametrically opposite each other to the rotational axis of the drive shaft 7.1. The different design and arrangement of the torque transmission elements 8, 8.1, 8.2 with respect to a circumferential angle of the drive shafts 7, 7.1, 7.2 of 360° causes the disks 3, 3.1, 3.2 of the disk arrangements 2, 2.1, 2.2 to be disengaged from their Fig. 2 cannot be simultaneously adjusted to their open position.

[0030] The arrangement of torque transmission element 8 and actuator 10 in the Fig. 3 corresponds to the Fig. 2. If the drive shaft 7 is turned as shown by the arrow in Fig. 2, is adjusted clockwise by 90°, the driving pin 9.1 is inserted into the guide slot 20.1 of the actuator 10. In the course of a further rotation of the torque transmission element 8, the actuator 10 is adjusted in the opposite direction to the drive movement of the drive shaft 7 about the pivot axis 11, so that a tensile force acts on the link 12 connected to it in an articulated manner and the slats 3 of this slat arrangement 2, as in Fig. 5a, in their open position. This engaged position of torque transmission element 8 and actuator 10 corresponds to the arrangement of these two elements as shown in Fig. 4 shown.

[0031] Adjusting the drive shaft 7, and thus also the drive shafts 7.1 and 7.2, by the described angular segment of 90° does not result in any adjustment of the slats 3.1, 3.2 of the other slat arrangement 2.1, 2.2. Only when the drive shafts 7, 7.1, 7.2 have been moved by a further angular segment of 90° is a driver pin of the torque transmission element 8.1 inserted into a guide slot of the actuator 10.1 and, in the course of this further movement by the angular segment of 90°, has also adjusted the actuator 10.1 by 90°, so that the slats 3.1 of the middle slat arrangement 2.1 have now also been brought into their open position. Neither the slats 3 nor the slats 3.2 were adjusted by this further angular segment when the drive shafts 7, 7.1, 7.2 were adjusted.

[0032] A further rotational movement of the drive shafts 7, 7.1, 7.2 by an angular segment of 90° leads to a corresponding adjustment of the slats 3.2, the slat arrangement 2.2, so that after a rotational movement of the drive shafts 7, 7.1, 7.2 by a total of 270°, all slats 3, 3.1, 3.2 of the slatted roof 1 have been brought into their open position.

[0033] Starting from this open position, the slats 3, 3.1, 3.2 are brought into their closed position again by an angular segment of 90° by turning the drive shafts 7, 7.1, 7.2 in the opposite direction. Fig. 5c shows the slats 3, 3.1, 3.2 of the kinematically coupled slat arrangements 2, 2.1, 2.2 in an intermediate position during the process of pivoting them into their closed position.

[0034] The invention has been described using an exemplary embodiment. Without departing from the scope of protection defined by the applicable claims, numerous further embodiments for implementing the inventive concept will become apparent to those skilled in the art without the need for further explanation within the scope of these statements.
