An adjustable damping mechanism for a slat structure

Description

2 inconvenient because the locking mechanism must be unlocked before a user can move the slats to another desired position. Moreover, it has been established that such locking mechanisms are subject to wear and incorrect use, whereby the locking mechanism will not always act correctly on the slats and locking will not take place. 5 There is therefore a need for a slat structure in which unwanted movement of the slats can be prevented in a simple manner, without preventing desired movement. Furthermore, there is a need for a damping mechanism in which the braking force exerted by the damping mechanism on the tiltable slats is adjustable, so that a specific setting of the damping mechanism can take place depending on the specific application placement of the slat structure. Moreover, there is a need to position the damping mechanism discreetly, particularly when a minimalist arrangement is desired,whereby the operation and adjustment of the damping mechanism can be performed quickly and efficiently without dismantling parts of the slat structure or without the normal operation of the tiltable slats being hindered or compromised. SUMMARY20 To meet the needs described above, a first aspect of the invention provides for a lamellar structure containing: -at least two tiltable lamellae, each lamella tiltable around a respective lamellar axis;25 -a coupling mechanism configured to tilt the at least two tiltable lamellae together; and -at least one elongated profile: -to which the at least two tiltable lamellae are tiltable by means of their respective lamellar axes; and30 BE2025 / 5065 3 -where the coupling mechanism is positioned so that it is located at least partially within the elongated profile, where the lamellar structure further contains a damping mechanism acting on the coupling mechanism,and where the damping mechanism is configured to exert an adjustable braking force: - during the tilting of at least two slats, and - during the holding of at least two slats in a stationary position. The use of a damping mechanism with an adjustable braking force ensures that a desired braking force can be set that can act on the tiltable slats, whereby a user will be able to move the slats against the braking force and place them in a desired position, and where the slats will be held in this desired position by the damping mechanism when no force or a force lower than the set braking force is exerted on the slats. Moreover, a damping mechanism with an adjustable braking force ensures that in the event of wear the braking force can be adjusted without the damping mechanism being further damaged or needing to be replaced. According to an optional design, a lamella structure20 is provided in which the coupling mechanism contains at least one tooth and at least two gears,where each gear is mounted on a correspondingly lateral axis of the at least two respective tilting lamellae, and where the at least two gears mesh with at least one rack. 25 In this way it is possible to move all tilting lamellae simultaneously with each other via the coupling mechanism and where at the same moment the damping mechanism can exert the set braking force on all lamellae via the coupling mechanism. 30 BE2025 / 5065 4 According to an optional design, a lamella structure is provided in which the damping mechanism transmits the adjustable braking force to the coupling mechanism via at least one rack. By allowing the coupling mechanism to mesh directly or indirectly with at least one rack, it is possible to limit the movement of all tilting lamellae of the lamella structure simultaneously and to exert the same braking force on all tilting lamellae. According to an optional design, a lamella structure is provided in which at least one toothed bar, preferably 3 toothed bars,at least two gears are arranged on the first side of the 10, and where at least one rack, preferably three racks, are arranged on the second opposite side of the at least two gears. By using at least one rack on each side of the gears, a more stable installation without unwanted play between the coupling mechanism 15 and the damping mechanism can be obtained. Moreover, when each rack on each side is split into multiple racks,It is possible to provide a more cost-efficient design where the interrelationships and dimensions are not compromised. According to an optional design, a lamellar structure is provided in which the damping mechanism is at least partially inserted into the elongated profile between two gears of two nearby lamellae. In this way, it is possible to incorporate the damping mechanism invisibly or almost invisibly into a profile of the lamellar structure. Moreover, in this way, it will be ensured that the damping mechanism is less susceptible to contamination or exposure to damage. According to an optional design, a lamellar structure is provided whereby the damping mechanism further contains an adjustable braking mechanism and a 30 BE2025 / 5065 5 coupling gear, whereby the coupling gear is positioned so that it is at least partially located within the elongated profile, whereby the coupling gear is connected to at least one toothed bar,and whereby the adjustable braking mechanism acts on the clutch gear. In this way, it is possible to direct the adjustable braking force exerted by the adjustable braking mechanism to act more precisely on the clutch gear, which in turn will ensure that the entire gear and the associated gears and lamellae are braked in their movement. According to an optional design, the adjustable braking mechanism contains at least one friction element and a control mechanism, whereby the control mechanism is configured to clamp at least one friction element against the clutch gear in order to adjust the braking force exerted on the clutch gear. In this way, the braking force can be regulated more easily by clamping at least one friction element more or less against the coupling gear using the control mechanism. When the friction element is pressed against the coupling gear with greater force, the coupling gear will be more hindered from rotating around its axis. If, in this case, a user wishes to move the tilting lamellae,The movement of the lamellae will be inhibited because each lamella is connected to the coupling gear via its respective lamella counter axis, gears, and rack. When the coupling gear experiences a greater braking force, each lamella will experience a similar braking force. According to an optional design, the adjustable braking mechanism is located at least partially within the elongated profile, whereby the adjustment mechanism is accessible and / or operable via the outside of the elongated profile and on the side of the tiltable lamellae. In this way, the adjustable braking mechanism is discreetly contained within the lamella structure.where care is taken to ensure that its operation remains possible without BE2025 / 5065 6 complete or partial disassembly of the elongated profile or other parts of the lamella structure. According to an optional design, the adjustment mechanism consists of an adjustment bolt and a nut. The adjustment bolt and nut are configured to clamp at least one friction element against the coupling gear. In this way, a simple adjustment mechanism is obtained whereby the adjustment bolt, by screwing it deeper or less deep into the nut, will ensure that a higher or lower braking force can be obtained. According to a further optional design, one end of the adjustment bolt is located on the outside of the elongated profile, whereby the tilting lamellas are movable over the end of the adjustment bolt. Because the end of the adjustment bolt is positioned lower than the end of the tilting lamellas,the lamellae will always remain movable without being hindered by the protruding end of the adjusting bolt. Moreover, it is possible for a user to manipulate the adjusting bolt by positioning the lamellae in such a way that the end of the adjusting bolt is not blocked by one of the lamellae, and a user can easily adjust the braking force without the need for partial or complete disassembly of the lamella structure. According to an optional design, the adjustable brake mechanism contains at least two friction elements, with at least one friction element placed on each side of the coupling gear. By providing a friction element on each side of the coupling gear, the available contact surface between the friction elements and the coupling gear will increase, which has a beneficial effect on the transmission of the braking force by the brake mechanism to the coupling gear. According to an optional design, the coupling mechanism is entirely,and the damping mechanism preferably located entirely within the elongated profile. In this manner, a compact and minimalist design is obtained which is moreover shielded from environmental influences. According to an optional design, the damping mechanism further contains a fastening element, whereby the fastening element is connected to at least one elongated profile and whereby the fastening element is configured to limit the movement of the damping mechanism relative to at least one rack. In this way, a damping mechanism will be obtained that is firmly connected to a profile of the lamella structure, whereby, regardless of the magnitude of the braking force exerted by the braking mechanism, the mutual freedom and freedom of movement between the damping mechanism and the rack will be limited to a minimum. According to an optional design, the fastening element comprises a 15 elongated bracket,where the elongated bracket is provided with a first opening at a first end and a second opening at a second end. The slat counter axis of a first slat is configured to be inserted into the first opening, while the slat counter axis of a second slat is configured to be inserted into the second opening. 20 In this way, the fastening element can be attached to the elongated profile via additional points, whereby any movement of the fastening element, and thus by extension the damping mechanism,will be prevented. As a result, the damping mechanism will not be able to pivot and will eventually be located partially between the teeth of the tooth.25 Preferably, a first limiting ring is provided which is configured to secure the lamellar axis of the first lamella in the first opening of the elongated bracket, and a second limiting ring is provided which is configured to secure the lamellar axis of the second lamella in the second opening of the elongated bracket.30 BE2025 / 5065 8 The limiting rings are clamped onto their respective lamellar axes after the lamellar axis has been placed in the respective opening. In this way, it is still possible for the lamellae to pivot around their respective lamellar axes in the opening of the elongated bracket, while the elongated bracket through the lamellar side assemblies are held in place.5 According to an optional design, the elongated bracket is further provided with a central opening,where the coupling gear is configured to be connected to the elongated bracket of the fastening element by means of the adjusting bolts and the central opening. In this way, a whole can be obtained in which the various parts are connected to each other in a compact assembly. According to an optional design form, the fastening element is a tubular fastening element, in which the coupling gears and at least one friction element are positioned centrally in the tubular opening of the fastening element by means of the adjusting bolt. Preferably, the opening of the tubular fastening element is elliptical, oval, round, rectangular, crescent-shaped, teardrop-shaped,etc. In this way, the adjusting bolt will act on the coupling gears via the tubular mounting element at both the top and bottom, and exert a uniformly distributed braking force on the coupling gear. According to an optional design, the mounting element is a U-shaped mounting element consisting of two parallel or nearly parallel legs which are connected by a connecting part. The mounting element is provided with a first and respectively second opening at the end of each of the legs, where the adjusting bolt is positioned in the first and second opening. At least one friction element coupling gear is positioned between the adjusting bolts and the connecting part, where the adjusting bolt is configured to determine the distance between the two legs in order to adjust the braking force exerted on the coupling gear. According to an optional design, a lamellar structure is provided in which the damping mechanism furthermore contains an adjustable braking mechanism,and 5 where the adjustable braking mechanism acts directly on at least one rack. In this way, a simplified damping mechanism is obtained. According to an optional design, the mounting element is a U-shaped mounting element consisting of two parallel or nearly parallel legs which are connected by a connecting part. The mounting element is provided with a first and respectively second opening at the end of each of the legs, where the adjusting bolt is positioned in the first and second opening. The mounting element is further provided with a first and / or a second projection at the end of one of the legs,where the first or second projection is provided with a friction element. The regulating bolt is configured to determine the distance between the two legs in order to set the braking force exerted by the friction element on at least one toothed bar. In this way, it is possible to directly exert a braking force on the one or more toothed bars via the friction elements mounted on one or both projections, by simply clamping together the two legs of the U-shaped mounting element. According to an optional design, the fastening element is a U-shaped fastening element consisting of two parallel or nearly parallel legs connected by a connecting part. The connecting part is equipped with an adjustment mechanism, whereby the two parallel or nearly parallel legs are configured to engage with at least one elongated profile. The adjustable braking mechanism comprises a spring equipped with at least one friction element,where the at least one friction element is configured to exert a direct braking force on the at least one rack. The control mechanism is configured to determine the position of the spring relative to the connecting part and the at least one friction element relative to the at least one rack and thus to set the braking force exerted by the friction element on the at least one rack. 5 According to an optional design, the mounting element is a U-shaped mounting element consisting of two parallel or nearly parallel legs connected by a connecting part. The connecting part is equipped with a control mechanism, whereby the two parallel or nearly parallel legs are configured to engage with the at least one elongated profile. The adjustable braking mechanism comprises a damper,where the damper is configured to exert a direct braking force on at least one rack. The control mechanism is configured to determine the position of the damper relative to the connecting part and relative to at least one rack in order to set the braking force exerted by the damper on at least one rack.

Unless otherwise defined, all terms as used, including technical and scientific terms, have the meaning as a specialist usually understands them. As a further guideline, the definitions are included for further explanation of terms used here. Figure 1 shows a schematic and execution form of a lamella structure 10. According to the execution form shown, the 15 lamella structure 10 contains four elongated profiles 300, of which only the top, left, and right elongated profiles 300 are visible in Figure 1. The elongated profiles 300 together form the perimeter of the lamella structure 10 around an inner surface 14. The inner surface 14 of the lamella structure 10 is thus situated within the rectangular perimeter formed by the 20 elongated profiles 300. The inner surface 14 is primarily formed by the space surrounded by the various elongated profiles 300 of the lamella structure 10.or in other words the internal surface whose perimeter is determined by the elongated profiles300 that border this internal surface14. 25 The elongated profiles300 are preferably arranged so that their perimeter forms approximately a quadrilateral or a rectangle. Preferably, the elongated profile 300, which forms part of the lamella structure10, is arranged so that one side of it borders or borders the internal surface14 of the lamella structure10. There can be countless variations on the dimensions of the lamella structure10 and of those 30 BE2025 / 5065 15 elongated profiles300; ranging from, by way of example, 0.1 m to 4 m per side; for example 0.5 m to 3 m, for example 0.5 m, 1 m or 2 m, and so on. The elongated profile300 is preferably manufactured from a rigid material, such as aluminium, steel, copper or any suitable plastic. 5 As further visible in Figure 1, the design of the lamella structure 10 contains multiple infill elements or tiltable lamellas100,100'which extend between two opposing elongated profiles300of the lamella structure10. It is clear that these lamellas at least partially fill the inner surface14of the lamella structure10.10 As further visible in the execution form of Figure 1, the lamella structure 10 contains removable cover plates330which are removablely attached to the elongated profiles300 in order to thus provide access to a coupling mechanism200and damping mechanism400. It is clear that these cover plates330are elongated15 plate-shaped elements whose longitudinal axis extends parallel to the longitudinal axis of the respective elongated profile300. Figure 2 shows a schematic and design form of a lamella structure10 in which only one elongated profile300 is shown and to which various tiltable20 lamellas100,100' are attached. The tiltable lamellas100,100' are positioned in such a way that a control mechanism 417 that is part of the damping mechanism 400 is visible along the side of the elongated profile 300 that faces the inner surface 14. 25 The elongated profile300 contain an H-profile310 whose flanges320 extend parallel to the central longitudinal plane16 (see figure 1) of the lamella structure10. It is clear that, according to the execution example shown, the flanges320 of the elongated profiles300 form an outer surface of the lamella structure10 that extends parallel to the central longitudinal plane16. In other words, the flanges320 of the elongated profiles300 that form the perimeter of the lamella structure10 determine respectively a so-called front and back side of the lamella structure10, which is typically the most visible side of the lamella structure10 and which determines the framing of the inner surface14. These front and back sides of the lamella structure5 10,and the associated flanges320of the elongated profiles300of the lamellar structure10thus extend parallel to the central longitudinal plane16, or in other words, parallel to the plane determined by the longitudinal direction W of the lamellar structure10, as schematically shown in Figure 1.10. The elongated profile300th thus ensures that a space is available within which the various components of the coupling mechanism200and damping mechanism400can be enclosed and thus shielded from external influences. 15 Figure 3 shows a first design of the damping mechanism 400, in which the damping mechanism 400 is built together with the coupling mechanism 200 into the elongated profile 300. The elongated profile 300 is shown only partially to clearly illustrate the assembly of the coupling mechanism 200 and damping mechanism 400. 20 As shown in Figure 3, each tiltable lamella 100, 100' is provided with a respective lamella 102, 102' whereby the lamella 100,can be positioned tiltable within the lamella structure10. Each lamella counter axis102,102' is connected to the oblong profile300 by means of an opening in the oblong profile300. The inside of the oblong profile is provided with two 25 racks202,204 whereby the longitudinal axes of the racks202,204 extend parallel to the longitudinal axis of the respective oblong profile300. A gear 210,210' is further provided that is mounted on a lamella counter axis102,102' to move together with the lamella counter axis102,102', whereby the gear 210,210' can engage with the teeth of both the upper rack202 and the lower rack204.30 BE2025 / 5065 17 When all tiltable lamellae100,100' have been inserted through their respective openings in the elongated profile300, and each corresponding gear210,210' has been mounted on its respective lamella counter axis102,102', both the upper202 and lower204 rack shall be enclosed between the wall of the H-shaped elongated profile300 and the gears210,210'. When a user grasps a tilting lamella 5 100 and rotates it around its lamella counter axis 102, the respective gear 210 will rotate along with the lamella 100. In turn, the gear 210 will drive the racks 202, 204, causing them to move left or right within the elongated profile 300. Due to the movement of the racks 202, 204, the other gears 210' will also be driven, as these gears 10 engage with the teeth of the racks 202, 204. Consequently, the gears 210' will cause the same rotation of their respective lamella counter axis 102', causing the corresponding lamella 100' to tilt together with the lamella 100 and assume the same position as the lamella 100 manipulated by the user. The racks202,204 and gears210,210 thus together form the coupling mechanism200 that ensures that all lamellae100,100 move together without each lamella100,100' must be individually adjusted by a user. In the configuration shown in Figure 3, both an upper 202 and a lower 204 rack are provided. The configuration with two racks 202 and 204 ensures a robust and stable unit in which only a minimal clearance will occur between the components. Although this configuration is preferable, it is nevertheless possible to provide only one rack, for example only the upper rack 202 or lower rack 204, into which the respective gears 210 and 210' will mesh. Moreover, it is possible to assemble the tooth bar 202,204 from multiple tooth bars, for example two, three or more individual and shorter tooth bars, which, when fitted into the elongated profile 300, can together form the upper tooth bar 202 or the lower tooth bar 204. A design in which each tooth bar 202,204 is composed of two-part tooth bars is shown in Figure 5,where each rack section is to be fitted with a coupling piece at its outermost end. It is furthermore recommended to connect these rack sections to each other via the coupling piece in order to together form the rack and guarantee the transmission of the tilting movement from a first lamella to the other lamellas. Figure 3 further shows a first design of a damping mechanism4005, in which the damping mechanism400 can transmit an adjustable braking force to the coupling mechanism200, whereby a user must overcome the braking force exerted by the damping mechanism400 during the tilting of the slats before being able to place the slats100,100' in a new position. Moreover, the damping mechanism40010 ensures that the slats100,100' cannot move without the set braking force being overcome, for example by a gust of wind briefly acting on the slat structure10. In this way, the damping mechanism400 is able to exert a braking force on the coupling mechanism200 during the tilting of the slats100,100'while the lamellae100,100'are in a stationary position15. As visible in Figure 3, the damping mechanism 400 is partially inserted into the elongated profile 300 between the gears 210, 210 of two nearby lamellae 100, 100. 20 Figures 4A to 4D show different views of the first design of the damping mechanism 400. Figure 4A is an exploded view showing the various parts of the first design of the damping mechanism 400. The damping mechanism 400 contains an adjustable brake mechanism 25, 410, a coupling gear 412 and a fastening element 420. The adjustable brake mechanism 410 in turn contains two friction elements 414, 414, an adjustment bolt 416 and a nut 416b, where each friction element 414, 414 is positioned on either side of the coupling gear 412 and by means of the adjusting bolt416a and nut416b can be pressed against the clutch gear412 with an adjustable force. The adjusting bolt416a and nut416b thus together form an adjustment mechanism416 that is capable of the friction elements414,414' to clamp against the coupling gear 412 and thereby exert an adjustable braking force on the coupling gear 412, where the adjustable braking force is a direct result of the position of the adjusting bolt 416 relative to the nut 416b.5 The fastening element 420 attaches the damping mechanism 400 with the lamellar side assemblies 102,102' from two neighboring lamellae 100,100'. In this way, the fastening element 420 is able to prevent, or at least limit, the movement of the damping mechanism 400 relative to the rack bars 202 and 204.10 The fastening element is in the design shown in figures 3, 4A to 4D and 5 an elongated bracket 420, where the elongated bracket 420 is attached to a first end provided with a first opening421 and at a second end provided with a second opening422. The lamella axis102 of the first lamella100 is inserted into the first opening421, while the lamella axis102 of the second lamella15 100, near the first lamella100,in the second opening422 is inserted. The elongated bracket420 is further provided with a central opening423 into which the adjusting bolt416 can be inserted in order to thus attach the friction elements414,414' and the coupling gear412 to the elongated bracket420 together with the nut416b (see Figure 4B and 4C). Consequently, the adjusting bolt416 is able to move in the 20 central opening423, whereby the head of the adjusting bolt416 will be located partially or wholly outside the central opening423 on the side of the tilting lamellae100, 100', or recessed relative to this central opening423. As an alternative design, it is also possible to make the head of the regulating bolt 416a sufficiently large so that it can move relative to the central opening 423, without the head itself being partially or fully recessed in the central opening 423. It should be noted here that the first friction element 414 is located between a wall of the elongated bracket 420 and the coupling gear 412,while the second friction element414' is located between the coupling gear412 and the head of the adjusting bolt416a. The friction elements414,414' are preferably designed as ring-shaped elements, each provided with a central opening through which the friction elements414,414' can be slid onto the shaft of adjusting bolt416a. Preferably, it is possible to provide a wear-resistant material with which the friction elements414,414' can be coated, or of which they can consist, such as polymers, composites, ceramic materials, carbon-5 based materials, etc., in particular nylon or rubber. Preferably, the surface of the friction element414,414' is such that at least half, at preferably 3 / 4th, preferably making contact with the entire side of the coupling gear 412. 10 In Figure 4, mainly the front side 426 of the elongated bracket 420 is visible,while in figure 4C mainly the rear side 427 of the elongated bracket 420 is visible. The front side 426 of the elongated bracket 420 is oriented towards the lamellae 100,100' after assembly in the elongated profile 300, while the rear side 427 of the elongated bracket 420 is oriented away from the lamellae 100,100' after assembly. 15 Furthermore, a recess 424 is provided on the rear side 427 of the elongated bracket 420 into which the nut 416 can be inserted. The shape of the recess 424 is complementary to the shape of the nut 416b, thereby preventing a rotating movement of the nut 416b relative to the elongated bracket 420. Because the nut 416 is positioned in the recess 424, the adjusting bolt 20 416aeng indeschroefvandemoer416benze endus kanbe screwed into demoer416b,gendemoer416b is fixed. Demoer416b will consequently behave as a stationary nut.

Figure 4D shows a top view of the compound damping mechanism 400, in which the friction elements 414, 414' are placed on either side of the clutch gear 412. From Figure 4D it is clear that when the adjusting bolt 416a is screwed deeper into the nut 416b, the friction elements 414, 414' will be pushed against the sides of the clutch gear 412 with a greater force 30 BE2025 / 5065 21. As a result, the friction elements 414, 414' will exert a greater braking force on the clutch gear 412, making it more difficult for the clutch gear 412 to rotate. When the adjusting bolt 416a is screwed less deeply into the nut 416b, the friction elements 414, 414' will press against the sides of the 5 with a lower force coupling gear 412 be pushed,whereby the braking force applied to the coupling gear 412 will be lower and the coupling gear 412 can rotate more easily around its axis. Figure 5 shows an exploded view in which the first design of the damping mechanism 400 is shown in relation to the elongated profile 300,10, the coupling mechanism 200 and the tilting lamellae 100,100'. Figure 5 shows a first limiting ring417 which, after the elongated bracket420 has been placed around the lamellar axis102,102' by means of the openings421,422, will be clamped around the lamellar axis102 of the first lamella100, while a second limiting ring417' will be clamped around the lamellar axis102'15 of the second lamella100' in order to attach the elongated bracket420 to the lamellar axis102,102' and prevent the elongated bracket420 from sliding off the lamellar axis102,102'. Depending on which limiting rings 417,417' are clamped on the respective lamellar axis102,102', the elongated bracket420can move on the slats cantilever axles102,102' relative to the elongated profile 300. Preferably, the limiting rings 417,417' are placed on the slats at the welds 102,102' such that a minimum clearance is provided between the front 426 of the elongated bracket 420 and the inner wall of the elongated profile 300. Furthermore, Figure 5 shows an opening 340 in the elongated profile 300 through which the head of the adjusting bolt 416 can be inserted and is thus accessible 25 between the slats 100,100'. The adjusting mechanism 416 will thus be partially located in the elongated profile 300, whereby the adjusting mechanism 416 is operable via the adjusting bolt 416 along the outside of the elongated profile 300 and at the side of the tilting slats 100,100'. When the tilting slats 100,100'in a closed configuration, the slat will at least partially conceal the control bolt from view, whereas when the tiltable slats are arranged in an open or partially open configuration,the adjusting bolt 416a between the lamellae 100 and 100' will be visible and accessible. When the fastening element 420 with the coupling mechanism 200 and the lamellae at 102,102' are connected, a user can adjust the braking force that will be exerted by the damping mechanism 400 on the coupling mechanism 200 by bringing the adjusting bolt 416a deeper or shallower into the nut 416b and thus adjusting the friction of the friction elements 414,414' on the coupling gear 412. 10 Figure 6 shows a cross-section of the lamella structure 10 in which the damping mechanism 400 and fastening element 420 as shown in figures 4A to 4 and the coupling mechanism 200 are located in the elongated profile 300. Although not visible in figure 6, only the head of the control bolt 416 may be completely 15 or partially outside the elongated profile 300,while all other parts of the whole are positioned on the inside of the elongated profile300. In this way it is possible to shield the coupling mechanism200 and the damping mechanism400 from the surroundings and thus prevent damage or contamination of the various moving parts.20 Figure 7 shows the design of the lamella structure10 as shown in figure 2, where the elongated profile300 is only partially shown and where the second design of the damping mechanism400 is shown. In the design shown in Figure 7, the damping mechanism25 400 contains an adjustable brake mechanism410, a coupling gear412 and a fastening element430. Similar to the first design, the brake mechanism410 contains two friction elements414,414' (see Figure 8a), an adjusting bolt 416a and a nut416b, where each friction element414,414'positioned on either side of the clutch gear 412 and can be pressed against the clutch gear 412 by means of the adjusting bolt 416 and nut 30 BE2025 / 5065 23 416b with an adjustable force. The adjusting bolt 416 and nut 416b thus together form an adjustment mechanism 416 that is capable of clamping the friction elements 414, 414' against the clutch gear 412 and thereby exerting an adjustable braking force on the clutch gear 412, where the adjustable braking force is a direct result of the position of the adjusting bolt 416 at 5 relative to the nut 416b. The fastening element 430 attaches the damping mechanism 400 with the elongated profile 300 between the slats and assemblies 102,102' of two neighboring slats 100,100'. In this way, the fastening element 430 is able to prevent the movement of the damping mechanism 400 relative to the racks 202 and 204, 10 to at least limit it. The fastening element is in the design shown in figures 7, 8A and 8. Leg-tubular fastening element 430, where the coupling gear 412 and the friction elements 414,414'are positioned centrally in the tubular opening of the fastening element 430 by means of the adjusting bolt 416a. The 15 design as shown in figures 7, 8A and 8B is an elliptical tubular fastening element 430, provided with two opposing flat side walls 431,431'each connected to two rounded side walls 432,432'. The two opposing flat side walls 431,431'each provided with an opposing central opening which are positioned such that the adjusting bolt 20 416 can be brought through the openings of the tubular fastening element 430 in order to attach the coupling gear 412 and the friction elements 414,414' to the tubular fastening element 430. At the height of the quadrangles of the tubular fastening element 430 notches 434 are provided each, whereby the teeth of the dental rods202,204be able to pass unhindered without making contact with the tubular fastening element 430when the tubular fastening element 430is connected to the elongated profile 300. It should also be noted that the first friction element414 is located on the inside of the first flat sidewall431 and the coupling gear412, while the second friction element414 is located between the coupling gear412 and the inside of the second sidewall431 of the tubular mounting element430. The friction elements414,414 are preferably ring-shaped elements, each provided with a central opening through which the friction elements414,414 can be slid onto the shaft of adjusting bolt416. Preferably, the surface of the friction element414,414 is such that it makes contact with at least half, preferably 3 / 4, or preferably the entire side of the coupling gear412. Although not shown, it is possible to provide the inside of the elongated profile with protrusions, against which the rounded sides432,432' of the fastening element 430 are positioned against. When a first 10 protrusion on a first rounded side 432 is placed closer to the upper tooth bar 202, while a second protrusion on the second rounded side 432 is placed closer to the lower tooth bar 204, the movement of the fastening element 430 will be prevented and only minimal rotation of the fastening element 430 relative to the tooth bars 202, 204 is possible. 15 The fastening element 430 is connected to the elongated profile 300 by an opening in the elongated profile 300. Thus, the adjusting bolt 416 will pass through the opening in the elongated profile 300, through the opening in the side wall 431', through the opening in the friction element414', via the opening in the coupling gear412, via the opening in the 20 friction element414, via the opening in the side wall431 can subsequently be stowed in the nut416b. When the fastening element430 is connected to the coupling mechanism200,can a user adjust the braking force that will be exerted by the damping mechanism400 on the coupling mechanism200 by bringing the adjusting bolt416a deeper or less deep into the nut416b and thus adjust the friction of the friction elements 414,414' on the coupling gear412. Although not visibly shown in the figures, the head of the adjustment bolt 416a will be located outside the oblong profile 300, while all other parts of the whole are positioned on the inside of the oblong profile 300. The 30 BE2025 / 5065 25 adjustment mechanism 416 will thus be located partially inside the oblong profile 300, whereby the adjustment mechanism 416 is still operable via the adjustment bolt 416 along the outside of the oblong profile 300 and on the side of the tiltable slats 100,100'. When the tiltable slats 100,100' are arranged in a closed configuration, the slat 100 will at least partially obscure the adjustment bolt 416 from view, whereas when the tiltable slats 100,100' are arranged in an open or partially open configuration,the adjustment bolt 416 between the slats 100 and 100 will be visible and accessible. In this way it is possible to shield the coupling mechanism 200 and the damping mechanism 400 from the surroundings and thus prevent damage or contamination of the various moving parts. Figure 9 shows the design of the slat structure as shown in Figure 2, where the elongated profile 300 is only partially shown and where the third design of the damping mechanism 400 is shown. In the design as shown in Figure 9, the damping mechanism 400 contains an adjustable brake mechanism.a coupling gear 412 and a fastening element 440. The brake mechanism 410 according to the third design form contains only one friction element 414 and an adjusting bolt 416a. The friction element 414 is a conical element that is positioned in the opening of the coupling gear 412 and protrudes partly above and / or below the coupling gear 412. Consequently, the edges of the friction element 414 can be brought into contact with the top and / or bottom of the coupling gear 412 by positioning the adjusting bolt 416a. The fastening element is in the design form as shown in figures 9, 10A and 10. A U-shaped fastening element 440 consisting of two parallel or nearly parallel legs 441,442whoareconnectedbyaconnectionpart443. The fastening element 440 is provided with a first 446 opening at the end of the first leg 441 and a second 447 opening at the end of the second leg 442. The first 446 and second 447 openings are positioned relative to each other in such a way that the adjusting bolt 416 can be inserted simultaneously into the first 30 BE2025 / 5065 26 446 and second 447 openings. The first opening 446 is provided with a screw thread into which adjusting bolt 416 can be screwed. The coupling gear 412, provided with the friction element 414, is positioned between the adjusting bolt 416 and the connecting part 443. Both the first leg 441 and the second leg 442 can provide a recess into which the end of the friction element 5 414 can be brought to obtain a better alignment of the coupling gear 412 between the legs 441, 442. When a user wants to adjust the brake force, the user can operate the adjustment bolt 416a and thus move the legs 441, 442 towards each other or push them away from each other. When the legs 441,442 are pulled towards each other, the friction element 414 will be pushed against the coupling gear 412 with a greater force. The adjusting bolt 416 is therefore configured to adjust the braking force exerted on the coupling gear 412 via the mutual distance between the two legs 441, 442. Figure 11 shows the design of the lamella structure as shown in Figure 2, where the elongated profile 300 is only partially shown and where the fourth design of the damping mechanism 400 is shown. In the design as shown in Figure 11, the damping mechanism 400 contains an adjustable brake mechanism 410 and a fastening element 450. The brake mechanism 410 according to the fourth design contains two friction elements 20 414, 414' and an adjusting bolt 416a. The fastening element is in the form shown in figures 11, 12A and 12. Leg U-shaped fastening element 450 consisting of two parallel or nearly parallel legs 451,452dieverbondenzijndooreenverbindingsdeel453. The fastening element 450 is provided with a first 456 opening at the end of the first leg 451 and a second 457 opening at the end of the second leg 452. The first 456 and second 457 openings are positioned relative to each other in such a way that the adjusting bolt 416 can be inserted into the first 456 and second 457 openings simultaneously. The first 456 opening is provided with a thread into which adjusting bolt 416 can be screwed. 30 BE2025 / 5065 27 The fastening element 450 is further provided with a first 458 and a second 459 projection at the end of the first leg 451. The first 458 and the second 459 projection are provided with a friction element 414, 414' and will, when the fastening element 450 is placed in the elongated profile 300, rest on the upper side of the rack bars 202 and 204. The adjusting bolt 416 is configured to determine the distance between the two legs 451, 452 in order to thus determine the braking force exerted by the friction element 414, 414 on the rack bars 202,204 to be set. The design as shown in figures 11, 12A and 12B is provided with two 10 protrusions on which a friction element is mounted. However, it is also possible to provide only one protrusion with a friction element that will only act on one of the racks 202 or 204. When a user wishes to set the braking force, the user can operate the adjustment bolt 416a15 and thus move the legs 451, 452 towards each other or push them away from each other. When the legs 451, 452 are pulled towards each other, the friction elements 414, 414 will be pushed against the racks 202 and 204 with a greater force. The adjustment bolt 416 is therefore configured to, via the mutual distance between the two legs 451,452 to adjust the braking force applied to the rack bars 20220 and 204. Figure 13 shows the design of the lamella structure as shown in Figure 2, where the elongated profile 300 is only partially shown and where the fifth design of the damping mechanism 400 is shown. In the design as shown in Figure 13, the damping mechanism 400 contains an adjustable brake mechanism 410 and a fastening element 460. The brake mechanism 410 according to the fifth design contains a spring 465, two friction elements 414, 414', an adjustment bolt 416a and a nut 416b. Alternatively, it is possible to replace the nut 416b with an opening in the sheet metal of the fastening element 460 in which a screw thread is provided. The fastening element in the form shown in figures 13 and 14 is a U-shaped fastening element 460 consisting of two parallel or nearly parallel legs 461, 462 which are connected by a connecting part 463. The two parallel or nearly parallel legs 461,462 are configured to engage with the elongated profile 300. The fastening element 460 is further equipped with an adjustment mechanism 416 comprising a U-shaped spring element 465, where the ends of the spring element 465 are each covered with a friction element 414, 414'. However, it is possible not to equip the ends of the U-shaped spring element 465 with a friction element 414, 414', in which case the necessary braking force on the racks 202, 204 will be exerted solely by the force exerted by the spring element 465. The friction elements 414, 414' are configured to exert a braking force directly on the racks 202, 204. The adjustment mechanism 416 is configured to determine the position of the spring465 relative to the connecting part46315 by screwing in or out the adjusting bolt416a into the nut416b, and consequently the friction elements414,414' relative to the rack bars202,204 in order to thus determine the braking force exerted by the friction elements414,414' on the rack bars 202,204 to be set. 20 Figures 15A and 15B show cross-sections of the lamella structure in which the damping mechanism 400 as shown in figures 13 and 14 and the coupling mechanism 200 are located in the oblong profile 300 and in which the adjusting bolt 416a is placed at a different depth relative to the connecting part 463. 25 In the design as shown in figures 15A and 15B, the adjusting bolt 416 with a screw head 416c, for example provided with a hexagonal notch, is located within the oblong profile 300, as are all other parts. The adjusting mechanism 416 will thus be located entirely within the oblong profile 300, whereby the adjusting mechanism 416 and in particular the screw head 416c of the adjusting bolt 416a 30 BE2025 / 5065 29 will be accessible via one of the removable cover plates 330 of the elongated profile 300. A user wishing to operate the control mechanism will consequently have to remove cover plate 330,and subsequently, using for example a screwdriver or Allen key, must reach into the elongated profile300 to turn the head416c of the adjusting bolt416 in one or another direction. Unlike the other versions, it is not relevant whether the tilting slats100,100 are arranged in a closed configuration, or whether they are arranged in an open or partially open configuration. When the cover plate330 is mounted, it is possible to shield the coupling mechanism200 and the full damping mechanism400 from the surroundings and thus10 prevent damage or contamination of the various moving parts. When a user wishes to adjust the brake force, the user can, after removing the cover plate330, operate the screw head416c of the adjusting bolt416a via the elongated profile300 and thus put the spring element465 under tension.15 As an alternative design, it is possible to insert the adjusting bolt416a upside down into the U-shaped spring element465,where the screw head416c is aligned with an opening in the elongated profile300, and where it is thus still possible to operate the screw head416c of the adjustment bolt416 via the opening in the elongated profile300, without the cover plate330 needing to be removed.20 In figure 15, the adjustment bolt416 is positioned in such a way that the friction elements 414 and 414' are placed against the rack bars 202 and 204, without them exerting a greater force on them. In figure 15, the adjustment bolt416 is brought in the direction of the lamellae100 (see arrow A, figure 15B) and the legs of the spring element 465, on which the friction elements 414, 414' are placed, will be pushed inwards.25 (see arrows Ben C, figure 15B) whereby the friction elements 414,414' be pushed against the rack bars 202 and 204 with greater force. The adjusting bolt 416 was consequently configured to bend the spring element 465 via its positions relative to the connecting part 463 and thus obtain an adjustable braking mechanism 410 whereby the braking force acts directly on the rack bars 202 and 204.30 BE2025 / 5065 30 Figure 16 shows the design of the lamella structure as shown in Figure 2, where the elongated profile 300 is only partially shown and where the design of the damping mechanism 400 is shown. In the design as shown in Figure 16, the damping mechanism 5 400 contains an adjustable brake mechanism 410 and a fastening element 470. The brake mechanism 410 according to this design contains a damper 475, an adjustment bolt 416 and nut 416b. The fastening element in the design as shown in Figures 16 and 17 is a U-shaped fastening element 470 consisting of two parallel or nearly parallel legs 471,472 which are connected by a connecting part 473. The two parallel or nearly parallel legs 471, 472 are configured to engage with the elongated profile 300. The fastening element 470 is further provided with an adjustment mechanism 416 that encloses the damper 475, whereby the outside of the damper 475 is covered with a friction element 414. In the design shown 15 in figures 16 and 17, only the outside of the damper 475 is covered with a friction element 414. However, it is possible that the complete damper 475 consists of a material such as rubber with which a similar friction can be obtained between the damper 475 and the racks 202, 204 on which the damper 475 will act. The damper475 is preferably a donut-shaped damper, so that the adjusting bolt416a can be connected via the opening in the damper475 to the U-shaped fastening element470 and engage with the nut416b. The friction element414 is configured to apply a braking force directly to the rack and pinion.204. The adjustment mechanism416 is configured to determine the position of the damper475 at 25 relative to the connecting part473 by screwing in or out the adjustment bolt416a into the nut416b. When the adjustment bolt416a is brought sufficiently to the end of the direction of the lamellae100,100', the adjustment bolt416a will push the damper475 against the inside of the elongated profile300, whereupon the damper475 will deform. In this way, the walls of the damper475 will be pushed against the rack bars30 BE2025 / 5065 31 202 and 204 in order to adjust the braking force exerted by the damper475 and the friction element414 on the rack bars202,204. Figures 18A and 18B show cross-sections of the lamella structure where the damping mechanism 400 as shown in figures 16 and 17 and the coupling mechanism 200 are located in the elongated profile 300. The regulating bolt 416 is shown in figures 18A and 18B at different depths relative to the connecting part 473. In the design as shown in figures 18A and 18B it is clear that the screw head 416 of the regulating bolt 416 is located within the elongated profile 300,10 as well as all other parts. The adjustment mechanism416 will thus be located entirely within the elongated profile300, whereby the adjustment mechanism416 and in particular the screw head416c of the adjustment bolt416a will be accessible via one of the removable cover plates 330 of the elongated profile300. A user who wishes to operate the adjustment mechanism will consequently have to remove the cover plate33015, and then reach into the elongated profile300 with, for example, a screwdriver or Allen key to turn the screw head416c of the adjustment bolt416a in one direction or another. Similar to the fifth version, with this version it is also irrelevant whether the tilting slats100,100 are arranged in a closed configuration20, or whether they are arranged in an open or partially open configuration. When the cover plate 330 is mounted,is it possible to shield the coupling mechanism 200 and the entire damping mechanism 400 from the surroundings and thus prevent damage or contamination of the various moving parts.25 When a user wishes to adjust the brake force, the user can, after removing the cover plate 330, operate the screw head 416c of the adjusting bolt 416a via the elongated profile 300 and thus put the damper 475 under tension. BE2025 / 5065 32 As an alternative design, it is possible to insert the adjustment bolt 416a upside down into the damper 475, whereby the screw head 416c is aligned with an opening in the elongated profile 300, and whereby it is thus still possible to operate the screw head 416c of the adjustment bolt 416 via the opening in the elongated profile 300, without the cover plate 330 needing to be removed. 5 In Figure 18, the adjustment bolt 416 is positioned in such a way that the damper 475 touches the inside of the elongated profile 300 and the toothed bars 202 and 204 without applying much force. In Figure 18, the adjustment bolt 416a is brought in the direction of the lamellae 100 (see arrow A,figure 18B) and the damper 475 equipped with the friction element 414 will be compressed and the walls of the damper 47510 will be pushed sideways (see arrows B and C, figure 18B) whereby the friction element 414 is pushed against the rack bars 202 and 204 with greater force. The adjusting bolt 416 is consequently configured to deform the damper 475 via its positions relative to the connecting part 473 and thus obtain an adjustable braking mechanism 410 whereby the braking force acts directly on the rack bars 202 and 204. Although not shown in one of the figures,
