Description

The invention relates to a sliding folding shutter for closing and releasing at least a part of a building opening, in particular a window or a door, in particular for sun protection, according to the preamble of claim 1.

Sliding folding shops of the type mentioned in two, four or mehrflügliger execution are known from the prior art. They are used in particular as sun and sight protection or in a more massive embodiment as burglary and storm protection against gluts and doors application. Such sliding folding shops usually have at least two, preferably four or more loading elements, which are each connected to each other articulated. Thus, such a sliding folding shutter is composed of one or more whole or half pairs of shutter elements, each pair forming three vertical axes, namely a middle minor axis representing the central pivotal connection axis of the two shutter elements, and two peripheral main axes. All main axes lie in one plane, namely the closing plane. The first main axis of the first store element pair is usually immovable and, for example, pivotally fixed to the window frame. The rest of the main axes are guided linearly displaceable along a horizontal and perpendicular to the main axes extending locking axis, wherein the store element pairs are pivotally connected to each other about the two adjacent and considered as common main axes. In other words, the store elements, apart from the marginal first shop element, which is mounted only pivotable, but not displaceable, in addition to their respective window or door opening facing edge sides parallel to the closing plane slidably stored in at least one horizontal longitudinal guide rail. The free and last main axis is used to open and close the store and is coupled with adjustment means, such as a belt or cable, which is either manually or preferably electrically driven, for linear adjustment.

In the open state of the sliding folding store selbiger is pushed concertina like and the individual pivotally interconnected shop elements are aligned substantially perpendicular to the closing plane. In the fully closed state of the sliding-folding-loading, the individual store elements are almost in a common plane, which is parallel to the closing plane, and close - possibly together with a second sliding folding store - the window or door opening in front of them are arranged. In this case, the individual shop elements can only be almost, but not exactly in a common plane, because even in the closed position a slight zigzag alignment must be maintained to prevent mutual blocking of the store elements and a reopening of the store by linear displacement allow the main axes along the closing axis. Would the store elements in the closed state of the store in a common plane - so be aligned - and thus would be both the main and the minor axes almost or completely in the closing plane, the store elements would be to each other in Totpunktausrichtung and a collapse of the Loading by linear displacement of the main axes along the longitudinal guide rail would not be possible.

From the DE 35 13 630 C1 a folding door is known in which between the wings a spring arrangement is disclosed. One Disadvantage of such a spring arrangement is that the springs counteract the drive when closing, reaching the dead center due to the spring force and the limited driving force is prevented even in the closed state, the drive is subject to increased wear and the springs themselves also subject to wear. The arrangement of springs is not always feasible from Platzgründern.

To enable the dead center overcoming alternative drive devices have also become known.

From the WO 2004/074616 A1 is a leaflet gate with a drive device for opening and closing known, wherein a pivotable by a drive motor about a vertical axis pivoted lever cooperates with the first wing member.

In the EP 1 816 298 A1 There will be described a sliding folding shutter for closing and releasing at least a part of a window or door opening. A drive device has a pivotable about a vertical pivot axis of a drive motor between an open and a closed position pivot lever which cooperates with the first shutter member for pivoting thereof between its open and closed position. In addition, the drive device comprises a pivotable by a further drive motor between an open and a closed position about a vertical pivot axis additional pivot lever, which cooperates with the third loading element for pivoting thereof between its open and closed position. Since the pivot lever act directly on the shutter elements in non-parallel, substantially perpendicular direction to the closing plane, the dead center of the Store elements are overcome to each other, so that the store elements in the closed state of the store can be aligned with each other.

A disadvantage of such a pivot lever drive is in particular that for each pair of store elements a separate pivot lever drive is provided and the existence of obvious and environmental influences suspended pivot lever is not always able to meet both aesthetic and functional requirements.

The object of the invention is therefore to provide a sliding folding store of the type mentioned above, which has a simple and largely integrated into the sliding folding store drive and its loading elements in the closed state of the sliding folding store have an alignment in a common plane.

This object is achieved by the realization of the features of the independent claim. Features which further develop the invention in an alternative or advantageous manner can be found in the dependent claims.

The invention is based on aligning at least one pair of store elements in its closed position in dead center, wherein the first loading element and the second loading element are aligned flat or parallel to the closing plane, and by means of a secondary guide member, in the region of the minor axis on the first loading element or on the second Store element or disposed therebetween, and a mechanically adjustable receptacle, which is arranged in that portion of the edge region of the slide-Falt-Laden, in which the first Nebenführungsglied is located in the vicinity of the closed position, to overcome the dead center orientation to open and to close. For this purpose, according to the invention, a first auxiliary drive is provided for such adjustment of the receptacle, that the secondary guide member is receivable and releasable in the receptacle.

Furthermore, the sliding folding shutter has detection means, in particular a first sensor, by means of which a position of the auxiliary guide member in the vicinity of the closed position formed by the active region of the receptacle on the secondary guide member can be detected.

The receptacle and the auxiliary drive are designed and the detection means are arranged and formed in such operative connection with the auxiliary drive, that the secondary guide member in the vicinity of the closed position in at least partially vertical direction to the closing plane for leaving the closed position and Totpunktüberwindung from the recording led out and is releasable and to achieve the closed position and the dead center alignment in the recording insertable and receivable.

The invention thus makes it possible to realize a just-oriented in the closed state and located in dead center sliding Falt-Laden, with no disturbing and visually striking additional elements that adversely affect the aesthetics of the sliding folding store and increase the susceptibility to failure can.

The FIGS. 1a to 1c . 2a to 2e and 3a to 3c each show an embodiment, which is why the respective associated figures are described in part together and the renewed explanation of already introduced features and reference numerals is omitted.

It should be noted that the illustrations are schematic illustrations, wherein the proportions of the individual elements have been deliberately changed to improve the visibility of certain features. Especially For better visibility of the margins, a large thickness of the store elements was chosen.

The FIGS. 1a . 1b and 1c show in a schematic plan view a sliding folding shutter 1a for closing and releasing at least a part of a building opening, in particular a window or a door. The sliding folding shutter 1a can serve in particular for sun or sight protection or for wind and weather protection as well as burglary protection.

The sliding folding shutter 1a has a first loading element 10, which is pivotally mounted in the region of its first side edge 11 about an immovable vertical first main axis 51, which is located in a vertically extending closing plane 3. The first main axis 51 is - as well as the other main axes - to be understood as a geometric axis. Preferably, however, in practice it may also be a mechanical axis, for example the pin of a hinge attached to the second side edge 11. The first main axis 51 forms the pivotable connection between the first loading element 10 and the frame of the building opening, for example the window frame.

In general, among the first side edges in each case that side edge of the store element is to be understood, which shows in the open, ie in accordion folded state of the folding slide store to the building opening and to the main axes, whereas under the second side edges of each on the other, opposite Side of the store element away from the building opening and to the minor axis facing side edge is to be understood.

A second loading element 20 is in the region of its second side edge 22 with the first loading element 10 in the range of the second side edge 12 is connected pivotably about a vertical first minor axis 61. As with the major axes, the minor axes are geometric axes, but they can also be formed by physical axes, in particular hinge elements.

The second loading element 20 is in turn pivotally mounted in the region of its first side wheel 21 about a displaceable vertical second main axis 52 which lies in the closing plane 3. The second main axis 52 is guided in a linearly displaceable manner along a horizontal closing axis 4 extending perpendicular to the vertical second main axis 52 and in the closing plane 3 by means of a first main guide element 56. In other words, the first main axis 51 and the second main axis 52 are parallel and lie in the vertically extending shooting plane 3, wherein the distance of the two parallel main axes 51 and 52 can be changed by moving the second main axis 52 in the direction of the locking axis 3.

Horizontally in the edge region of the sliding folding store 1a and parallel to the closing axis 4 extends at least one main guide rail 80, in which the first main guide member 56 is guided linearly displaceable. The first main guide member 56 is arranged in the region of the second main axis 52, in particular at the upper or lower edge of the second loading element 20. In the embodiment shown, the second major axis 52 passes through the main guide member 56, therefore, in plan view, the first main guide member 56 is not graphically separable from the second major axis 52. The first main guide member 56 is, for example, a first runner within the main guide rail 80, which has only one mobility parallel to the locking axis 4 and around the vertical second major axis 52 around.

A main drive 81 is directly or indirectly coupled to the first main guide member 56 such that the first main guide member 56 can be displaced linearly along the closing axis 4. The coupling can take place directly, for example by means of a belt drive within the main guide rail 80, or indirectly, for example, by another, especially third and / or fourth shop element, which is directly or indirectly connected to the second shop element 20, by means of the main drive 81 is adjustable and thus at the stop of the respective store elements, the first main guide member 56 mitverstellt.

By directly or indirectly forced displacement of the first main guide member 56 along the locking axis 4, it is possible, the first shop element 10 and the second shop element 20 of a in FIG. 1a 1, in which the first loading element 10 and the second loading element 20 are folded like an accordion and respectively pivoted away from the closing plane 3, into an in Figure 1c shown in the first closed position C1, in which the first loading element 10 and the second loading element 20 are unfolded and each hinged to the closing plane 3 to close and open in reverse order, as in FIGS. 1a and 1c shown.

In the in Figure 1c shown first closed position C1 of the two store elements 10 and 20 are selbige according to the invention in a dead center alignment. In other words, in the first closed position C1, the first loading element 10 and the second loading element 20 are each aligned essentially parallel to the closing plane 3. U Under the Totpunktausrichtung is generally a substantially parallel orientation of the store elements to understand in which a collapse, so opening the store elements by exerting force on the main guide member is difficult or impossible because the minor axis is so close to the closing level 3 or even on the side the building opening is that the store elements are blocked. The dead center alignment is thus an alignment region of the loading elements, which is determined not only by the position of the minor axis to the closing plane but also by friction in the joints and the hinge geometry.

According to the invention, a first secondary guide member 66 is arranged in the region of the first minor axis 61 on the first loading element 10 or on the second loading element 20 or in between. In the embodiment according to the FIGS. 1a . 1b and 1c This secondary guide member 66 is arranged on the second loading element 20 at the upper edge. The first secondary guide member 66 is designed in particular as a driver, as a bolt or as a guide angle.

The region of the minor axis is to be understood in particular in each case in particular that half of the store elements which adjoins the respective minor axis.

Furthermore, the sliding folding shutter 1a according to the invention comprises a mechanically adjustable first receptacle 71, which is arranged in that section of the edge region of the sliding folding shutter 1a, in which the first secondary guide member 66 is in the vicinity of the first closed position C1. The first receptacle 71 is a first auxiliary drive 73 for such adjustment of the associated with the first receptacle 71 that the first secondary guide member 66 in the first receptacle 71 can be received and released. By means of first detection means 74, in particular a first sensor, a position of the first secondary guide member 66 can be detected, within which the first secondary guide member 66 is formed in the vicinity of the first closed position C1 formed by the active region of the first receptacle 71 on the first secondary guide member 66. This close range is in FIG. 1b illustrated. In other words, the vicinity of the first closed position C1 is that of this closed position C1 near the region within which the first receptacle 71 can receive the first secondary guide member 66 and act on this mechanically. This effective range of the first receptacle 71 on the first secondary guide member 66 is limited to said near range. The proximity can be characterized by the pivoting angle between the closing level 3 and the respective store element 10 and 20, which is less than 30 °, preferably less than 20 °, in particular less than 15 °, in particular less than 10 °. The effective range or near range is such that the area of the dead center alignment is always within the effective range or near range.

The first receptacle 71 and the first auxiliary drive 73 are formed in such a way and the first detection means 74 are arranged and formed in such operative connection with the first auxiliary drive 73, that the first secondary guide member 66 in the vicinity of the first closed position C1 in at least partially vertical direction Closing plane 3 for leaving the first closed position C1 and Totpunktüberwindung from the first receptacle 71 can be brought out and released and to reach the first closed position C1 and the Dead center alignment in the first receptacle 71 inserted and can be accommodated.

In other words, the first receptacle 71 is adjustable in at least partially perpendicular direction to the closing plane 3 such that the first receptacle 71 within the vicinity of the first closed position C1 on the first secondary guide member 66 a force in at least partially vertical direction to the closing plane 3 to overcome the dead center as well as to reach the first closed position C1 can exercise.

In a further development of the invention, the first receptacle 71 is formed as the first, in particular rail-shaped, catch flap 71, which can be swung out and pivoted in such a manner around a substantially vertical catch flap axis 72 extending perpendicular to the closing axis 4 and which is designed such that the first secondary guide member 66 in the vicinity of the first closed position C1 for exiting the first closed position C1 and Totpunktüberwindung from the first rail-shaped catch flap 71 can be brought out and released by the swinging and to achieve the Totpunktausrichtung and the first closed position C1 in the first rail-shaped catch flap 71 by pivoting inserted and receivable is.

The first catch flap 71 can be arranged above or below the main guide rail 80 or form a particular rail-shaped section of the main guide rail 80.

FIG. 1b shows the store elements 10 and 20 at the edge of the vicinity and the effective range of the first catch flap. The operative connection is such that the first catch flap 71 at Transition from the first open position, FIG. 1a , in the vicinity of the closed position, FIG. 1b , is swung out for receiving the first secondary guide member 66 about the first catch flap axis 72 in the direction of the first secondary guide member 66. As soon as the first secondary guide member 66 is in the effective range of the first catch flap 71, which is detected by means of the first detection means 74 based on the position of the first main guide member 52, the first catch flap 71 pivots and thus takes the first secondary guide member 66 in the direction perpendicular to the closing plane 3, so that a parallel alignment of the shutter elements 10 and 20 within the range of Totpunktausrichtung, ie the first closed position C1, is taken as in Figure 1c shown.

In a further development of the invention, the first receptacle 71 and the first auxiliary drive 73 are formed and the first detection means 74 are arranged and configured and are in such operative connection with the first auxiliary drive 73 that the first secondary guide member 66 in a position of the loading elements 10 and 20 outside the first closed position C1 and the vicinity of the first closed position C1 is pivoted, such FIG. 1a shown by the solid line of the first catch flap 71. Alternatively, the first catch flap 71 is swung out in this area outside the vicinity, as shown by the dashed representation of the first catch flap 71 in FIG. 1a shown.

The first auxiliary drive 73 can be formed by an electric motor, which is provided specifically for pivoting the first catch flap 71, wherein the first detection means 74 are formed as an electrical sensor, in particular as an electrical contact switch, which determines the position of Shop elements within the near range signaled. For controlling the first auxiliary drive 73, a control unit 75 is provided which is in signal communication with the first auxiliary drive 73 and the first detection means 74, in particular also with the main drive 81, and is designed to produce the operative connection.

Alternatively, it is possible for the first detection means 74 to be formed by a mechanical member which is in mechanical engagement with the first receptacle 71 for adjusting it mechanically depending on the position of the loading elements, the auxiliary drive 73 being provided by the mechanical engagement and the main drive 81, which drives the first receptacle 71 indirectly via the mechanical operative connection is formed.

In the FIGS. 2a to 2e an extended by two more store elements 30 and 40 sliding folding store 1b is shown. This sliding folding shutter 1b has, in addition to the features and feature possibilities of the sliding folding shutter 1a FIGS. 1a to 1c the following features.

The sliding folding shutter 1b has a third loading element 30 which, in the region of its first side edge 31, is pivotably connected to the second loading element 20 in the region of its first side edge 21 about the displaceable vertical second main axis 52. A fourth loading element 40 is pivotably connected in the region of its second side edge 42 to the third loading element 30 in the region of its second side edge 32 about a vertical second secondary axis 62. The fourth shop element 40 is pivotably mounted in the region of its first side wheel 41 about a displaceable vertical third main axis 53 which lies in the closing plane 3. The third major axis 53 is along the perpendicular to the third major axis 53 and in the closing plane 3 extending horizontal locking axis 4 guided by a second main guide member 57, in particular in the main guide rail 80 linearly displaceable, so that the horizontal distance between the second main axis 52 and the third main axis 53 is adjustable. In the embodiment shown, the third main axis 53 passes through the second main guide member 57, which is why the second main guide member 56 is not graphically separable from the third main axis 53 in plan view. The vertical main and minor axes 51, 52, 53, 61 and 62 are parallel to each other, the main axes 51, 52 and 53 are in the shooting planes 3.

The main drive 81 is coupled directly or indirectly, for example, by means of a belt drive with the second main guide member 57, that the third loading element 30 and the fourth loading element 40 from a second open position O2, FIG. 2a in which the third loading element 30 and the fourth loading element 40 are folded like an accordion and are respectively pivoted away from the closing plane 3, into a second closed position C2, Figures 2c . 2d and 2e in which the third loading element 30 and the fourth loading element 40 are unfolded and pivoted to the closing plane 3, by direct or indirect linear displacement of the second main guide member 57 along the locking axis 4 in particular by means of the main drive 81 can be closed and opened in reverse order.

The sliding folding shutter 1b is in this case designed such that it depends on an overall open position O, FIG. 2a in the first open position O1 and second open position O2, so that the building opening is released, via an overall intermediate position I, Figure 2c , in the first open position O1 and second closed position C2, in an overall closed position C., FIG. 2e in the first closed position C1 and second closed position C2, so that the building opening is closed, can be closed by the linear displacement of the second main guide member 57 and opened in the reverse order.

In the second closed position C2, the third loading element 30 and the fourth loading element 40 are aligned in the dead center direction and in each case substantially parallel to the closing plane 3. In the area of the second minor axis 62 on the third loading element 30 or on the fourth loading element 40 or in between, a second secondary guide element 67 is arranged. In the embodiment according to the FIGS. 2a to 2e this second sub-guide member 67 is arranged on the fourth loading element 40 at the upper edge. The second secondary guide member 67 is designed in particular as a driver, as a bolt or as a guide angle. The region of the minor axis is to be understood in particular in each case in particular that half of the store elements which adjoins the respective minor axis.

In addition, the sliding folding shutter 1b comprises a mechanically adjustable second receptacle 76 which is disposed in that portion of the edge region of the slide folding shutter 1b, in which the second secondary guide member 67 in the vicinity of the second closed position C2 and the overall intermediate position I is located. As in the case of the first receptacle 71, the second receptacle 76 is a second auxiliary drive, which in the embodiment shown is formed by the first auxiliary drive 73, associated with such adjustment of the second receptacle 76, that the second secondary guide member 67 in the second receptacle 76 is receivable and releasable , By means of second detection means 79, in particular by means of a second sensor, is a position of the second Secondary guide member 67 can be detected, within which the second secondary guide member 67 is formed in the region formed by the effective range of the second receptacle 76 on the second secondary guide member 67 near the second closed position C2 and the total intermediate position I.

Since the first sub-drive 73 and the second sub-drive are formed as a common sub-drive 73, the first receptacle 71 and the second receptacle 76 are pivotally coupled. In one possible development, the first detection means 74 and the second detection means 79 are designed as common detection means.

This close range is in FIG. 2b illustrated. In other words, the vicinity of the second closed position C2 is that of this closed position C2 near the region within which the second receptacle 76 can receive the second secondary guide member 67 and can act on this mechanically. This effective range of the second receptacle 76 on the second secondary guide member 67 is limited to said near area. The near zone can be characterized by the pivoting angle between the closing plane 3 and the respective loading element 30 and 40, which is less than 30 °, preferably less than 20 °, in particular less than 15 °, in particular less than 10 °. The effective range or near range is such that the area of the dead center alignment is always within the effective range or near range.

The second receptacle 76 and the first auxiliary drive 73 are configured in this way and the second detection means 79 are arranged and configured in such operative connection with the second auxiliary drive 78 that the second secondary guide member 67 is in the vicinity of the second closed position C2 and the overall intermediate position I . FIG. 2b , in at least partially perpendicular direction to the closing plane 3 for leaving the second closed position C2 and the total intermediate position I and Totpunktüberwindung from the second receptacle 76 herausführbar and releasable and to reach the second closed position C2 and the overall intermediate position I and the dead center in the second receptacle 76 is insertable and receivable. In other words, the second receptacle 76 is adjustable in at least partially perpendicular direction to the closing plane 3 such that the second receptacle 76 is within the vicinity of the second closed position C2 and the overall intermediate position I, FIG. 2b , on the second sub-guide member 67 can exert a force in at least partially vertical direction to the closing plane 3 to overcome the dead center and to reach the second closed position C2.

By means of the control unit 75, which is in signal communication with the respective auxiliary drive 73 and the detection means 74 and 79, the operative connection described is produced.

In Figure 2d is according to the FIG. 1b the vicinity of the first loading element 10 and the second loading element 20 to the first closed position C1 and the overall closed position C, as shown in FIG. 2e prevails, illustrated. Since this vicinity and the inclusion and release of the first sub-guide member 71 in the first receptacle 71 has already been explained in connection with the first embodiment, reference is made to the above statements.

In the embodiment according to the FIGS. 2a to 2e is the second receptacle 76 as a second rail-shaped catch flap 76th formed, which is about a substantially vertical and perpendicular to the locking axis 4 extending second catch flap axis 77 such and is formed such that the second secondary guide member 67 in the vicinity of the second closed position C2 for leaving the second closed position C2 and for Totpunktüberwindung from the second rail-shaped catch flap 76 can be brought out and released by swiveling out and can be introduced and received in the second rail-shaped catch flap 76 by pivoting in order to achieve the dead center alignment and the second closed position C2.

Horizontally in the edge region of the sliding folding store 1c and parallel, in particular coaxially, to the closing axis 4 runs a secondary guide rail 70, in which the second secondary guide member 67 in the adjustment of the shift folding store 1b between the overall intermediate position I, Figure 2c , and the overall closed position C, FIG. 2e , along which the secondary guide rail 70 is guided in parallel, in particular coaxially, to the closing axis 4 linear.

The terms of the main guide rail 80 and the sub guide rail 70 are to be considered functional, ie, the rail guiding the main guide members 56 and 57 is functionally the main guide rail 80, and that guiding the second sub guide member 67 is functionally the sub guide rail 70. Despite this different terms, it is possible in the invention that a single rail takes on both functions and thus forms the main guide rail 80 and at the same time the secondary guide rail 70. In the case of the embodiment according to the FIGS. 2a to 2e forms a physical guide rail 90 functional the Main guide rail 80 and at the same time functionally the secondary guide rail 70, so they are coaxial, whereas in a further embodiment according to the FIGS. 3a to 3c these two functions are formed by two separate rails, namely a main physical guide rail 80 and a physical subguide rail 70.

The second catch flap 76 forms a section of the guide rail 90 which can be pivoted about the second catch flap axis 76 and whose cross-section substantially corresponds to that of the guide rail 90. The second catch flap 76 can be pivoted out of the course of the guide rail 90 and configured such that the second side guide member 67 in the vicinity of the second closed position C2 and the overall intermediate position I to leave the second closed position C2 and the overall intermediate position I off the guide rail 90 is herausführbar and releasable and to achieve the second closed position C2 and the overall intermediate position I and for further guidance within the guide rail 90 in the guide rail 90 can be inserted and received, as in the FIGS. 2c to 2e shown. Thus, it is possible that the second sub-guide member 67 is guided in the adjustment range of the shift-folding-loading 1b between the overall intermediate position I and the overall closed position C in the guide rail 90, so that the central stability of the third and fourth loading element 30th and 40 is increased in the region of the second secondary axis 62.

In FIG. 4 these second rail-shaped catch flap 76 and the second catch flap axis 77 are shown in detail view. The first catch flap 71 in particular has a corresponding structure.

It is also possible for the first catch flap 71 to form a portion of the guide rail 71, as in FIGS FIGS. 2a to 2e shown. The horizontal distance of the two catch flaps 71 and 76 along the closing axis 4 substantially corresponds to the horizontal distance of the first main axis 51 and the second main axis 52 in the first open position O1 of the first shop element pair 10 and 20, as in FIGS FIGS. 2b and 2c recognizable.

Thus, the main guide members 56 and 57 can pass through the two catch flaps 76 and 77 in the guide rail 90 unhindered, the second receptacle 76 and the first sub-drive 73 are formed and the second detection means 74 are arranged and formed and are in such operative connection with the first PTO 73, that the second secondary guide member 66 is pivoted in a position of the shutter elements 30 and 40 outside the second closed position C2 and the vicinity of the second closed position C2, as the FIG. 2a by the solid line of the second catch flap 76 and the Figures 2c and 2e demonstrate.

The embodiment according to the FIGS. 3a to 3c corresponds in essential parts of the embodiment of the functional FIGS. 2a to 2e , which is why only the essential differences are discussed below.

Instead of a guide rail 90, which includes the function of both the sub guide rail 70 and the main guide rail 80, these two rails are physically separate from each other. Horizontally in the edge region of the sliding folding store 1c and parallel to the closing axis 4 and spaced parallel to the main guide rail 80 extends the secondary guide rail 70, in which the second Secondary guide member 67 in the adjustment of the slide-folding-store 1c between the overall intermediate position I and the overall closed position C along the sub guide rail 70 is guided parallel to the locking axis 4 linear. Both designed as a catch flaps receptacles 71 and 76 are arranged as sections of the sub guide rail 70 in the same, with two receptacles 71 and 76 separate auxiliary drives, namely a first PTO 73 and a second PTO 78 are assigned. In the embodiment shown, the minor axes 61 and 62 pass through the first sub-guide member 66 and the second sub-guide member 67, respectively, and therefore the sub-guide members 66 and 67 are not graphically separable from the sub-axles 61 and 62, respectively, in plan view. Furthermore, the horizontal distance parallel to the firing axis 4 between the minor axes 61 and 62 and the main axes 51, 52 and 53 chosen larger than in the case of the previous embodiments. Instead of a horizontal spacing of the rails 70 and 80, which was also chosen for better illustration, it is possible to arrange the two guide rails 70 and 80 vertically spaced apart. Preferably, the sub guide rail 70 is disposed above the main guide rail 80.

An advantage of the embodiment according to the FIGS. 2a to 2e is that by means of a single guide rail 90, both the function of the main guide of the main guide members 51, 52, 53, and the secondary guide of the second secondary guide member 62, as well as above all the overcoming the dead center alignments can be achieved. Thus, it is possible to achieve a planar alignment of the shutter elements and overcoming the dead center without substantial and perceptible in normal operation additional elements.

Again, there is an advantage of the embodiment according to the FIGS. 3a to 3c in the possibility of retrofitting the sub-guide rail 70 including the receptacles 71 and 76, the auxiliary drives 73 and 78 including the detection means 74 and 79 and the secondary guide members 66 and 67 to an existing sliding folding shutter with a main guide rail 80th

In addition to the embodiments shown, the combination of individual respective features is possible, for example, an arrangement of the first receptacle 71 in the edge region of the sliding Falt-Laden and the second receptacle 76 in the main guide rail 80, the sub guide rail 70 or the combined guide rail 90. Other combinations according to the invention possible.
