A second folding shutter element (12B) is pivotably retained about a second axis (12B'), which can be moved perpendicularly to itself, near a second element edge (13B) that does not bend out, and can be moved along guides (16A, 16B) arranged perpendicular to the second element edge (13B) in pairs. Adjacent folding shutter elements (12A, 12B; 12C, 12D; . . . ) are pivotably connected to each other in pairs at the third element edges (15A, 15B) thereof, which bend out and which are opposite from and parallel to the first and second element edges (13A, 13B; . . . ), by means of a bend-out joint (14A, 14B; . . . ). Additional folding shutter elements are connected in pairs to the preceding folding element pair and/or a last folding shutter element freely protruding at the end is pivotably connected to the folding element pair(s) near the second, fourth, or further element edge (13B; . . . ) that does not bend out. At least one driving element (30) is provided, which can be moved along at least one of the guides (16A, 16B) and which drives at least one, preferably the last, of the second, fourth, or further element edge (13B, . . . ) that does not bend out, in the opening or closing direction, and which forcibly pivots the folding shutter elements (12B, 12C; . . . ) connected to at least one of the element edges (13B; . . . ) that do not bend out, in pairs in the opening or closing direction by means of at least one coupling element (32A, 32B, 32C).

Description

Faltladenanordnung with several rigid in itself Faltladenelementen, in particular with alternating buckling and not buckling element edges

FIELD OF THE INVENTION

The invention relates to a Faltladenanordnung with the features of the preambles of claims 1, 13 or 14. Accordingly, a first Faltladenelement is about a first, stationary with respect to a fixed or almost stationary axis near a non-buckling (first) element edge pivotally on the building indirectly or directly attached or attachable. A second Faltladenelement is pivotally supported about a transversely displaceable to itself second axis near a non-buckling second element edge and displaceable along perpendicular to the second element edge paired guides. The pairwise adjacent Faltladenelemente are connected at their first and second element edges parallel opposite, buckling third element edges in pairs by means of a Ausknickgelenkes pivotally connected to each other. It can connect more Faltladenelemente to the first two Faltladenelemente in pairs to the preceding Faltladenelementpaar. Furthermore, can

TECHNOLOGICAL BACKGROUND

From WO 2008/125343 A1 of the same Applicant a Faltladenanordnung is known in which near Ausknickenden element edge pairs a locking / unlocking and possibly Ausstell- and Heranzieheinrichtung are provided so that the Faltladenanordnung starting from a self-erecting in each capping Verschließanordnung any opening position is movable. Basically, this Faltladenanordnung is also suitable for several Faltladenelementpaare.

From FR 2600892 A1 a Faltladenanordnung for sloping Verandendächer is known in which the Faltladenelemente occupy even in the closed position no stretched position, but the adjacent Faltladenelemente already occupy an angular position with each other at their joint edges, so that Ausknickhilfsmittel are not required for a stretched position , When opening, rather, a successive complete buckling of the adjacent pairs of folding pallets takes place due to the predetermined slightly bent basic position of the folded shutter pairs.

From DE 20 2004 010 622 U1 a Faltladenanordnung is known as a door system, ie in a vertical orientation, which allows in its closed position a stretched position of the mutually aligned Faltladenelemente. Here, the last (third) Faltladenelement seen from the attachment edge as a door can be opened and closed without the adjacent Faltladenelementpaar is moved. All movements of opening and closing are done by hand.

PRESENTATION OF THE INVENTION Based on this, the present invention seeks to realize a Faltladenanordnung that allows three- and more multi-folded Faltladenanordnungen between a closed extended position and an open buckled position of the Faltladenelemente motor driven to move in a simple manner. To solve this problem, a Faltladenanordnung proposed with the features of claim 1. Accordingly, it is provided in a generic Faltladenanordnung that at least one movable along the guides drive element drives at least one, preferably the last, the non-buckling element edges in the opening and closing direction. By means of at least one coupling element, the folding shutter elements connected to at least one of the non-buckling element edges are forcibly pivoted in pairs in the opening or closing direction.

By the invention it is u. A. possible, in the horizontally extending Faltla- denelementen, in particular for vertical, but in principle also for inclined or horizontal openings to be closed, a lowermost, or last, cantilevered Faltladenelement in the opening and closing direction to drive motor. As a result, favorable lighting and / or ventilation conditions can be achieved and / or relatively large-area solar panels can be installed on the outside of the folded shutter arrangement in a favorable orientation. In the past, motorized opening and closing Faltladenanordnungen could only be realized with an even number of Faltladenelementen because the motor-driven, from the point of articulation of the Faltladenanordnung on a building farthest element edge had to be performed in the lateral guides.

Thus, on the one hand, folding-shutter arrangements with an arbitrary number of folding-shutter elements in an odd number can be realized by the invention. However, it is also possible, according to the invention, to realize folding shutter arrangements with an even number of folding shutter elements, such as two, four, six and more folding shutter elements. The opening and closing drive, as well as the buckling, pulling, locking and unlocking can be realized by the invention in a simple manner. The adjusting elements for this purpose can be comparatively simple in their construction and / or housed inconspicuously.

For the purposes of the invention, the area of the folded shutter arrangement is to be understood as the buckling element edges on which an element edge or an element edge pair moves away from the guides when opening the folding shutter arrangement transversely to the extension direction of the guides. In contrast, in the sense of the invention, a "non-buckling" element edge is one which, individually or in pairs, always remains in the plane of the guides or parallel thereto and is displaced only in the opening direction along the guides or parallel thereto The invention can be embodied in various ways: as a means for pivotally holding and, in particular in pairs, displacing the at least one non-buckling second element edge, at least one guide carriage which can be moved along at right angles to the second element edges can be provided Carriage is basically already known from WO 2008/125343 A1 for Faltladenanordnungen with only two Faltladenelementen.When, as preferred, the Faltladenanordnung more than two Faltladenelemente comprises such a carriage must two element edges in a pivotable manner .This is preferably done in such a way in that the at least one guide carriage has spaced-apart pivot bearings for the pivotal mounting of the adjacent folding shutter elements. If the pivot bearing thus separate measures on pivot bearing arms, thereby the desired alignment position of adjacent Faltladenelemente can be achieved in a simple manner and the torques occurring at the pivot bearings can be initiated regardless of the required borrowed distance to the guides in the carriage. The coupling points on the Faltladenelement for the Zwangsverschwenkung are preferably provided at or near the non-buckling element edge / n and therefore u. A. arranged largely unobtrusive. The coupling elements thus preferably act on the folded shutter elements in positions which are located at or near the non-buckling element edges.

The coupling of the movable drive element with the Faltladenelementen, which allows Zwangsverschwenken the Faltladenelemente in a folded position or back to an extended position, is particularly preferably by a (first) coupling element in the form of a thrust element for pivoting one of the Faltladenelemente in moving the movable drive element. As a thrust element z. B. a push rod-like arrangement into consideration, which leads to the fact that when moving the drive element in the opening direction, a torque is generated on one of the Faltladenelemente in the sense of swinging.

The Zwangsverschwenkmittel, in particular the thrust element or generally at least one of the coupling elements, may comprise a separate Winkelverstellmittel for at least one of the Faltladenelemente that increases the effective length of Zwangsverschwenkmittels separately or reduced, such. B. a linear drive. As a result, the effect of the drive element can be superimposed on the folding shutter element to be pivoted, both in the sense of a faster and in the sense of a slowed or less strong swiveling out. This angle adjustment means can be effective both time-parallel and with a time delay to the drive element.

In order to pivot another Faltladenelement when moving the movable drive element, at least one further (second) coupling element may be provided in the form of a thrust element. This can, as well as the (first) coupling element, similar push rod and possibly separately wirklängeveränderlich. In order to reinforce the action of the first and / or the second coupling element, the moving folding shutter element may comprise a pivoting arm connected thereto, preferably rigidly connected, actuatable by the coupling element. In this way, the coupling element can be arranged comparatively inconspicuous in the immediate vicinity of the guide rails and relatively large torques can be introduced into the affected folded shutter element for its pivoting. Unlike the prior art, for. ß. According to WO 2008/125343 A1, the displacement of the Faltladenelemente of a stretched position in a folded position and the pulling of the Faltladenelemente in the closed extended position at a location near the non-buckling element edges location can be introduced into the Faltladenelemente. By the coupling elements, the Faltladenelemente can therefore be withdrawn from its Ausknickstellung again in the extended position. Buckling and Pulling takes place in a visually very inconspicuous way, since the previously known Ausknick- and Heranziehelemente no longer need to be mounted in the region of the ausknickenden Faltelementkante.

A particularly favorable Faltladenelement pivoting is made possible by the fact that a (third) coupling element is used in the form of a pair of teeth. Their use is particularly simple and effective when intermeshing toothed segments or possibly gears are provided on the pivot axes of adjacent Faltladenelemente at the non-buckling and / or buckling element edges.

The Faltladenelemente could be at least partially equipped with solar cells. The latter can for example be included in the context of the Faltladenelemente. If at least one pair of Faltladenelementen are provided together with a self-supporting solar panel, thereby comparatively large So- larpanel surfaces are effectively aligned with the sun. At the same time a favorable shading effect can be achieved for the underlying space area. Under self-supporting solar panels is understood in the context of the invention that a corresponding inherent rigidity or stiffening agent, such. B. a stiffening grid or frame are provided.

In order to securely hold a Faltladenanordnung in the closed position even in wind attack, vandalism attack or other situations in position, known locking and unlocking means can be actuated by at least one movable along the guide drive means, in particular the drive means for opening and closing the Faltladenanordnung, is operatively connected to a Leerwegmittel, by which u. A. the locking and unlocking of at least one of the Faltladenelemente in or near the closed stretched position of the Faltladenanordnung and in particular near a Faltladenelement- edge is allowed. Such an arrangement is also independent of the features of claim 1 of independent inventive importance. It can also be used to drive buckling and / or harvesting equipment. The Leerwegmittel can optionally be drivingly connected via at least one extension means with the locking and unlocking means and / or with the Ausknick- and / or raising means for at least one of the Faltladenelemente, so that the locking and unlocking and / or buckling and / or If appropriate, it is also possible at the same time to remotely actuate at different positions along the folding shutter arrangement and preferably in the area of the buckling element edges. Such an arrangement is also independent of the features of claim 1 of independent inventive importance.

In principle, the (first) guide carriage can already be used as a movable drive element; This is especially true when the distance from the pivot point of the coupling elements on the carriage while driving through telescopic rails o. Ä. can change. A simple arrangement of the coupling elements is made possible by the fact that as a movable drive element min- at least one is arranged along perpendicular to the element edges arranged guides movable (second) guide carriage. This simplifies the pairwise pivoting of folding shutter elements adjacent to a non-buckling element edge pair.

The above-mentioned and the claimed components to be used according to the invention described in the exemplary embodiments are not subject to special conditions of size, shape, material selection and technical design, so that the selection criteria known in the field of application can be used without restriction.

Further details, features and advantages of the subject matter of the invention will become apparent from the dependent claims, as well as from the following description and the accompanying drawings, in which - by way of example - an embodiment of a Faltladenanordnung is shown. Also, individual features of the claims or of the embodiments may be combined with other features of other claims and embodiments.

DETAILED DESCRIPTION OF EMBODIMENTS

In the three-part embodiment according to FIGS. 1A to 1D, one of two vertical and parallel spaced guides 16A, 16B is visible, in which a first guide carriage 17A and a second guide carriage 17B are vertically movable. The uppermost of three Faltladenelementen 12 A, 12 B and 12 C is near the first (uppermost) element edge 13 A about a fixed axis 12 A 'pivotally mounted on an only indicated building 1 indirectly. A second folding shutter member 12B is pivotally supported about a second self-displaceable second axis 12B 'near a non-buckling second element edge 13B with respect to the first guide carriage 17A. The second, non-buckling element edge 13B is vertically displaceable along the guides 16A, 16B arranged in pairs at right angles to the second element edge 13B by means of the guide carriage 17A. The adjacent folding elements 12A and 12B form a (first) folded-shutter element pair. The folding shutter elements are connected to their th and second element edges 13A, 13B parallel opposing buckling third element edges 15A ,. 15B in pairs by means of a Ausknickgelenkes 14A pivotally connected to each other. A further (third) folding element 12C adjoins the folding element pair 12A, 12B at the end as the last folding element and has a freely projecting element edge 13C. The third Faltladenelement 12C is mounted near its upper element edge about a pivot bearing 17A ', which is located on the carriage 17A, cantilevered freely pivoting. The operation of the Faltladenanordnung now proceeds in the following manner: On the second (lower) guide carriage 17 B, which is vertically moved by guide rollers 17 C along the guides 16 A and 16 B, engages a drive element such as a drawstring 11 and in particular to upper and lower pulleys 11A, 11B extending toothed belt, the / in the region of an upper and / or lower guide roller 11A, 11B in both directions, in particular by an electric motor, can be driven. The drive means and the elongate guide carriage 17B are referred to collectively as drive element 30. On the second guide carriage 17B, a first coupling element 32A and a second coupling element 32B are each pivotally mounted. The first coupling element 32A is a push rod, which with its lower pivotable articulation point (pivot point 19A) on the second guide carriage 17B and with its upper pivotable articulation point (pivot point 19B) on the third Faltladenelement 12C at a distance and lateral offset below the pivot bearing 17A ' is fixed, so that a pivot arm 34 is formed and the first coupling element 32A can thereby exert a torque on the third Faltladenelement 12C. The second coupling element 32B is also designed as a push rod and pivotally connected, for example, at the same connection point with the second guide carriage 17B as the first coupling element. At its second, upper end, the second coupling element 32B engages a pivot arm 34B. This is the second Faltladenelement 12 B in the lower region rigidly, that is not pivotally connected, so that the pivot arm 34 B, a torque on the second folding loading element 12B exercises. On the first guide carriage 17A, the drive means thus only indirectly engages namely by means of the second coupling element 32B and the pivot arm 34B. Thus, the first carriage 17A is raised and lowered indirectly via the movement of the second carriage 17B.

If the second guide carriage 17B is moved upward from the closed and locked extended position shown in FIG. 1A (FIG. 1C), only a lower locking and unlocking device 40A is disengaged during the initial movement (FIG. 1B). This locking and unlocking means 40A comprises a short arm with a locking cutout 17B "and a locking stop 17B" laterally projecting in the lower end region of the third Faltladenelementes 12C. The boom has a slot 19 in which the lower pivot points 19A of the first and second coupling elements 32A and 32B can shift by a sufficient length. During the initial opening movement of the second carriage 17B these pivot points 19A move downwardly with respect to the boom, while the locking cutout 17B "moves upwards and finally releases the travel stop 17B '" as shown in phantom in FIG. 1A and in the detail of FIG 1B is shown in solid lines. The pivot point 19A is then located at the lower end of the slot 19. Further upward movement of the second carriage 17B thus leads to a lifting of both coupling elements 32A and 32B. This in turn means that the first coupling element 32A slightly swings the lower folding shutter element 12C and the second coupling element 32B slightly pivots the pivoting arm 34 about the pivoting part 17A 'and thus the second folding shuttering element 12B, ie in an extended position in a Ausknicklage, as in Fig. 2A is more apparent. Once the second Faltladenelement 12B is bent from its extended position into a slightly bent-over position, the first guide carriage 17A can move upwards under the lifting action of the first and second coupling element 32A and 32B along the guides 16A, 16B. In this case, the Ausknickbewegung the Faltladenelemente continues 12C and 12B. At the same time but also the first Faltladenelement 12A pivoted outwardly as a result of the Ausknickbewegung the second Faltladenelementes 12B and indirectly by means of the second coupling element 32B about the first axis 12A '. The first carriage 17A and the three Faltladenelemente 12A-C then follow the lifting movement of the second carriage 17B, as shown in Figures 1C and 1D can be seen. The second and third Faltladenelement 12B and 12C are so zwangsverschwenkt by the drive member 30 in pairs and thereby forcibly also the first Faltladenelement 12A is mitverschwenkt.

When closing the folding shutter assembly, the second carriage 17B is lowered and the first carriage 17A follows this movement due to its own gravity and supported by the gravity of the three Faltladenelemente 12A to 12C.

From the embodiment of Figure 2 it can be seen how one, in particular second, in the embodiment upper, locking and unlocking by the drive member 30 can also be operated: Two attached to the respective guide 16A or 16B push rod guide 21 A, 21 B lead sliding and approximately parallel to the guides, a push rod 21 with a, in particular lower, stop 21 C and a, in particular upper, push rod extension 21 D, which is flexible in itself or easily pivotally connected to the push rod 21. At its, in the example upper end, the push rod extension 21 D is pivotally connected to a locking and unlocking lever 40B "in the drive sense, so that a total, in the example upper, locking and unlocking means 40B is realized by a total of 42 designated A compression spring 21 F loads the upper locking and unlocking means 40B in the sense of an unlocking position, as shown in Figure 2. The drive element 30 serves to lock the drive element 30 to the locking device a stop 21 E is provided which comes into abutment with the stop 21 C at the end of the closing movement and at the same time pushes down the extension means 42 in the locking phase of the lower locking and unlocking means 40A. pushes, so that the upper locking and unlocking means 40 B enters its locking position, as is realized in a similar and yet to be described manner in the embodiments of Figures 7, 8 or 9. The second and third embodiment of Figures 3A to 3C and 4A to 4C differ from the first embodiment in that on the one hand five folding elements 12A to 12E, instead of 3 folding elements are provided. The two Faltelementpaare 12A, 12B and 12C, 12D are covered in the third embodiment according to Figures 4A and 4E in the closed state by a two Faltladenelemente covering solar panel 38, but that in each case only at the upper of the folding elements (12A and 12C) is attached to a Faltladenelementpaarung and therefore cantilevered out with its lower half when opening the Faltladenanordnung, as shown in Figure 4C can be seen. The difference of the second (Figures 3A to 3C) to the first embodiment is that in addition to the first coupling element 32A, a pair of gears 18A, 18B as (third) coupling element 32C are provided. These toothed segments are rotationally fixedly connected to the upper axis of rotation of the folded shutter element 12E with it and close to the lower element edge on the lower axis of rotation of the folded shutter element 12D. The centers of the gears 18A and 18B are aligned with the pivot bearings 17A 'and 17A "of the first guide carriage 17A and mesh with each other The same gear segment assembly and another carriage 17C are located on the non-buckling second element edge 13B at the transition between the The operation of the first coupling element 32A is the same as in the first embodiment, ie lifting of the second guide carriage 17B results in a slight buckling at the lower free end of the lower folding shutter element 12E the gear 18B, in particular by the same angular amount and takes the gear 18A and the fourth Faltladenelement 12D by the same angular amount in the sense of buckling In turn, the third folded shutter element 12C is forcibly bent and this in turn pivots the second folded shutter element 12B by means of a gear pair 18C, 18D at the non-buckling element edge 13B. This in turn leads to a forced pivoting of the uppermost Faltladenelementes 12 A about its stationary axis 12 A '. Overall, therefore, the entire Faltladenanordnung is evenly buckled with all five Faltladenelementen, as a result of the lifting movement of the second guide carriage 17B. The locking and unlocking by means of serving as Leerwegmittel 36 elongated hole 19 is the same as in the first embodiment. In the third embodiment of FIG. 4A-E, however, the pivotal coupling between the fourth and fifth Faltladenelement 12 D and 12 E takes place as in the first embodiment of FIG. 1A-D between the second and third Faltladenelement 12 B and 2C. Between the second and third Faltladenelement 12B and 12C, the pivotal coupling according to Fig. 4A-E is again as shown in Fig. 3A-D.

From the fourth exemplary embodiment according to FIGS. 5A to 5C, two telescoping surface elements 39A, 39B can be seen, which can be equipped, for example, with solar panels. These surface elements are preferably as wide as the Faltladenelemente and in the inserted state, they have an approximately equal to slightly shorter length as the Faltladenelemente between their joint areas. In the retracted state, as in Figure 5C at the lower surface element 39 B, the underlying building area is therefore not shaded. The useful surface of the multipart, telescoping surface elements 39A, 39B or the surface to be shaded can be changed via, in particular laterally arranged, telescopic guide rails. For disassembly and contraction different drive systems can be used. When using timing belts, as shown, the telescoping shots can be moved in both directions by a drive 39C, 39D in both directions. Alternatively, a belt or cable drive can be operated with a wind-up mechanism. To extend the telescopic arrangement, the weight can be used. Multi-part skins are special for lower folding shutter elements favorable, but can also be used advantageously in Faltladenanordnungen with two Faltladenelementen, such as, for example, according to Fig. 7A-C for the upper of the two Faltladenelemente. In this fourth exemplary embodiment according to FIGS. 5A to 5C, the difference from the first exemplary embodiment is that the first coupling element 32A is independently variable in length and can be designed, for example, as an electric spindle drive. As can be seen from the complete open position according to FIG. 5C, such an independent adjusting drive can be used to actuate the coupled positive swiveling device for the second and third folded shutter elements 12B and 12C such that the swiveling angles of these two folding shutter elements are different.

In the embodiment of Figures 6A to 6C, the buckling occurs in a three-part Faltladenanordnung in a manner known for example from WO2008 / 125343A1 way by means of a pulling and locking device 22, which also serves as Ausknickmittel and is actuated via a driver 22A, which is close to the closed position engages the pulling and locking device 22 in the direction of pulling and locking. When opening, the cam 22A causes a power-operated buckling of the upper Faltladenelementes 12A and the underlying associated Faltladenelementes 12B. Due to the coupling element 32C in the form of intermeshing tooth segments in the region of the non-buckling second element edge 13B and the lower Faltladenelement 12C is buckled and swung in the following movement, as already in connection with the embodiment of Figures 3A to 3E in principle apparent. The pulling, locking and Ausknickmittel 22 may be provided in principle (other than shown) instead of the upper Faltladenelement 12A, also on the middle (12B) or on the lower Faltladenelement 12C and its position between the upper and lower pivot of the associated Faltladenelementes is - basically - freely selectable. Accordingly, the initial position of the follower 22A, which is fixedly connected to an access band 11 and from which, as well as the carriage 17A, is driven up and down, is selected. Only one carriage 17A is needed. 7

fixed to a driven revolving drawstring 11, such as a toothed belt, at a fixed height distance from the also attached to the drawstring driver 22A is attached. A single drive thus causes the buckling and locking on the one hand and the opening and closing on the other.

In the embodiment of Figures 7A, 7B with only two Faltladenelementen 12A and 12B also finds a remote locking and unlocking and - ausknickung for one of the Faltladenelemente - in the drawing, for example, the upper Faltladenelementes 12A, instead of, as in principle already known from Figure 2 and how also at least partially apparent from Figures 8 and 9. In all of these embodiments, an extension means 42 serves to remotely actuate a higher or desired case of a lower-mounted locking and / or unlocking and / or buckling means 22 or 40B. In this case, the locking and / or unlocking and / or Ausknickmittel 40B fulfills a multiple function, because it can - as already used in the drawing and locking device 22 according to the embodiment of Figures 6A to 6C - as actively driven Ausknickmittel. Also in this embodiment, a lower locking / unlocking for the extended closed position (FIG. 7A) is provided on the driven carriage 17A, which can also be embodied by way of example as in FIGS. 2, 8 or 9. Illustrated in FIG. 7 are locking and / or unlocking means 40A and 40B, as they emerge in more detail from the detailed illustration according to FIG. 7D. The locking and / or unlocking means 40B corresponds in its essential structure to the likewise remotely operated version according to FIG 2. In addition, a double stopper 25A / B (Fig. 7D) is provided, which by means of the driver 22A permits a complete raising and lowering of the locking lever 22B or 40B ", as can be seen in Fig. 7C pivotally connected to the lower end of the push rod 21 of the extension means 42 locking lever 40A "along an orstfesten guide slot displaced. The embodiment of Figures 8A to 8E shows a dreiflüglige Faltladenanordnung, which differs from the embodiment of Figures 1A to 1C differs in that an additional Ausknickhilfsmittel 24 is provided. In the two variants shown in Figure 8, namely Figures 8A to 8C on the one hand and Figures 8D, 8E on the other hand, the Ausknickhilfsmittel 24 comprises a toggle lever assembly consisting of the levers 24A and 24B, which are pivotally connected to each other via a toggle joint 24C pivotally and as Ausknickmittel bear eg a toggle joint 24C associated roller 24D, which presses against one of the upper Faltladenelemente (in the drawing, the Faltladenelement 12A) as Ausknickunterstützung, as illustrated in Figure 8B. For actuating the Ausknickhilfsmittels 24 again an extension means 42 is provided, as it is already realized in connection with the push rod assembly 21 to 21 E in Figure 2 in the form of the outer side of the locking lever 40B "Due to the toggle lever arrangement comparatively strong Ausknick- forces on simple Therefore, the second coupling element 32B shown in Figures 8A to 8C can usually be dispensed with, and it is also possible to dispense with the first coupling element 32A, namely, when a third coupling element 32C It is also possible to provide or combine a toggle assembly according to Figures 8A to 8C with an upper locking and unlocking element, again providing relatively large locking forces with a low driving force Such a combination can be found in the exemplary embodiment according to FIGS. 9A, 9B.

Finally, the embodiment according to FIGS. 10A to 10D shows an alternative according to which a freely discharging folded shutter element can be pivoted without a second guide carriage and the entire folding shutter arrangement can be opened and closed with the same drive. For this purpose, the carriage 17A with a peripheral drive element, such as a toothed belt 11 can be raised and lowered and connected to the attachment point A with him. A coupling element ment 32A, as known for example according to the embodiment of Figures 1A to 1 D, is connected to the freely discharging Faltladenelement 12C in Ausschwenksinne and connected at its drive-side end via an attachment point B with the drive element, such as a toothed belt 11. To first buckle out of the extended closed position of Figure 10A Faltladenelemente a little, may be provided at the attachment point A of the guide carriage 17A, for example, a slot along which the attachment point A can move relative to the guide carriage 17B. In order to bring about a strong swinging out of the lower folded shutter element 12C during the lifting of the guide carriage 17A, the drive speeds of the attachment points A and B may be different. For example, the drive cables 11 ', 11 "over different sized upper and lower pulleys 11 A, 11 B run, so that at the same angular velocity of the pulleys, the pull cable 11', which is guided around the respective larger pulleys, moves faster than the other ,
