Description

Sliding folding shutter. The present invention relates to a sliding folding shutter for the sealing and release of at least a part of an opening of a building, particularly of a window or a door, particularly for sun protection, according to the preamble of claim 1. By the state of the art known sliding folding blinds of the type mentioned above in execution of two, four or more wings are known. They find particularly application as solar and visual protection or, in more massive execution, as protection against theft and against storms before windows and doors. Such sliding folding shutters generally have at least two, and preferably four or more shutter elements, which are respectively articulated in relation to each other. Accordingly, such a sliding folding shutter is composed of one or several whole pairs or means of blind elements, each pair constituting three vertical axes, namely a central auxiliary axis, representing the central tiltable joint axis of both blind elements, and two main axes at the edges. All main axes are in a plane, specifically the closing plane. The first main axis of the first pair of blind elements is generally fixed in a non-movable way and, for example, tiltable to the window frame. The remaining main axes are guided in a linearly displaceable manner along a horizontal closing axis and perpendicular to the main axes, the pairs of blind elements being linked in a tiltable manner between each other around the two adjacent main axes and considered as common . In other words, the blind elements, with the exception of the first edge blind element, which is supported only in a tiltable, but not movable way, are additionally supported on their respective lateral edges facing the window or door opening of form movable parallel to the closing plane in at least one horizontal longitudinal guide rail. The main and free main axis is used for opening and closing the blind and is coupled with graduation means, for example a belt or hoist transmission, operable either manually or preferably electrically, for linear regulation. In the open state of the sliding sliding shutter it is folded in the form of an accordion and the different blind elements, linked in a tiltable manner, are essentially aligned in a rectangular way to the closing plane. In the fully closed state of the sliding folding shutter, the different blind elements are practically located in a common plane, which extends parallel to the closing plane, and they seal - possibly together with a second sliding folding blind - the window or window opening. door to which they are located. For this, the different blind elements can be found only almost but not exactly in a common plane, since even in the closed position a slight zigzag alignment must be maintained, to avoid a mutual blocking of the blind elements and allow a new opening of the blind by linear displacement of the main axes along the closing axis. If the blind elements were in the closed state of the blind aligned in a common plane, that is to say, planes between each other - and then the main axes and the auxiliary axes coincided almost or totally with the closing plane, the blind elements they would find themselves in alignment with the neutral point of each other and it would not be possible to fold the blind by linear displacement of the main axes along the longitudinal guide rail. From DE 35 13630 C1 a folding door is known in which a spring arrangement is disclosed between the wings. A drawback of such a spring arrangement is that the springs counteract the drive during closing, the range of the neutral due to the spring force and the limited driving force is prevented even in the closed state, the drive is subjected to greater wear and the springs themselves are also subject to wear. The arrangement of springs is not always applicable for reasons of space. In order to allow the neutral point to be overcome, alternative drive devices are also known. From WO 2004/074616 A1 a folding leaf door is known with a drive device for opening and closing, a tilting lever cooperating by a drive motor around a vertical axis with the first wing element. EP 1 816 298 A1 describes a sliding folding window shutter for sealing and releasing at least a part of a window or door opening. A drive device has a tilting lever by a drive motor between an opening position and a closing position around a vertical tilting axis, which cooperates with the first blind element for tilting it between its position. open and its closed position. In addition, the drive device comprises an additional tilting lever that can be tilted by a further drive motor between an opening position and a closing position around a vertical tilting axis, which cooperates with the third blind element for tilting the same between its open position and its closed position. Since the tilt levers act directly on the blind elements in a non-parallel direction, essentially perpendicular to the closing plane, the alignment of the blind elements of the blind elements with each other can be overcome, whereby the blind elements can be found in the closed state of the blind aligned flat to each other.

A drawback of such a tilting lever drive consists particularly in that for each pair of blind elements a proper tilting lever drive must be provided and the existence of the visible and subject to inclement tilt levers does not always allow compliance with the aesthetic as well as functional requirements.

The purpose of the invention is therefore to provide a sliding folding shutter of the above-mentioned type, which has a simple and widely integrated drive in the sliding folding blind and whose blind elements present in the closed state of the sliding folding blind an alignment arranged on a common plane.

This purpose is achieved by performing the characteristics of the independent claim. Other features, which complement the invention in an alternative or advantageous manner, emerge from the dependent claims.

The invention is based on aligning at least a pair of blind elements in their closed position in neutral or neutral alignment alignment, the first blind element and the second blind element being aligned flat or respectively parallel to the closing plane, and in overcoming the neutral alignment zone by means of an actuation unit arranged in the horizontal frame that extends through the marginal area of the sliding folding shutter and capable of being tilted by means of a tiltable actuator arm by means of an actuator motor around a tilt axis. The subsequent opening of the pair of blinds is effected by a linear displacement of a main guide element by means of a main drive, the pair of blinds being tiltable from the marginal zone of the neutral alignment zone, in which the pair of blinds it is deployed and tilted towards the closing plane, to a first opening position, in which the pair of blinds is folded in the form of an accordion and is tilted out of the closing plane. The closing is done in reverse sequence.

In addition, the sliding folding shutter comprises a steering unit operatively linked in such a way with the main drive, the actuator motor and pick-up means to capture the position of the pair of blinds in the neutral alignment zone and configured in such a way that in the closed position of the pair of blinds, an opening sequence and a closing sequence can be executed. In the opening sequence it is governed

-

 the pair of blinds in the closed position - the actuation unit for tilting the pair of blinds outside the neutral alignment zone. Simultaneously or subsequently, there is a government of the main drive for the linear displacement of the main guide element in the direction towards the fixed main axis of the pair of blinds and towards the first open position. In the closing sequence it is governed - the pair of blinds being in the open position - the main drive for the linear displacement of the main guide element in the direction towards the fixed main axis of the pair of blinds and in the opposite direction to the closed position. Upon reaching the neutral alignment zone, a government of the actuation unit is produced to tilt the pair of blinds to the closed position.

According to a further embodiment of the invention, the pair of blinds is guided in such a way that in its closed position it is in an alignment of over neutral. Instead of the opening sequence described above, a further opening sequence can be applied according to the invention in which the main drive is first governed for the linear displacement of the main guide element in the opposite direction to the fixed main axis of the pair of blinds to overcome the alignment of over neutral and to achieve an absolute neutral alignment of the pair of blinds. In this alignment of absolute deadlock, there is now a government of the unit of action for tilting the pair of blinds outside the alignment of absolute deadlock and the area of alignment of neutral. The main drive is then governed for the linear displacement of the main guide element in the direction towards the fixed main axis to the open position.

According to the invention, the main drive and the actuation unit cooperate in such a way that the main drive takes over, in the tilt zone of the pair of blinds outside the neutral alignment zone, of the opening and closing of the pair of blinds by linear displacement of the main guide element, as long as the actuation unit allows the pair of blinds to be tilted within the neutral alignment area as well as out of this and towards it by a tilting movement. Consequently, the advantages of a linear drive are combined, that is to say its imperceptible and integrable housing within the framework of this high-power drive, with the advantages of a tilting drive, which allows the dead center of the pair of blinds to be overcome. The operating concept of the sliding folding shutter according to the invention does not suffer from the drawbacks of both driving concepts, namely the inability to overcome the neutral in the case of the linear drive and the striking additional elements, particularly a tilting arm of large dimensions, of the tilt drive, since only a tilt drive of small dimensions is required and acts only in the neutral alignment zone for overcoming the dead center.

The invention therefore allows the realization of a sliding folding shutter that is aligned flat in the closed state and is in alignment of neutral or even in alignment of neutral, being able to dispense with additional elements that disturb and are optically striking. which negatively influence the aesthetics of the sliding folding shutter and increase the tendency to breakdown.

In the following, the invention will be described in relation to an example of a specific embodiment by means of schematic illustrations, both of a general type and especially purely by way of example, with further details of the invention as well as its advantages. In the attached drawings:

Fig. 4e is a plan view of the sliding folding shutter in a second global open position.

Figs. 1 to 4e illustrate a common embodiment, whereby Figs. They are described in part jointly and the repeated description of characteristics and reference numbers already introduced is dispensed with.

It is stated that the representations are schematic illustrations, in which the proportions of the different elements have been intentionally altered for the best appreciation of certain characteristics. Particularly, for the best appreciation of the side edges, a large thickness of the blind elements has been chosen.

Figs. 1 and 2 as well as 3 to 4e show in respective views of lateral or inclined elevation or plan view a sliding folding shutter 1 for the sealing and release of at least a part of an opening of a building, particularly a window or a door. The sliding folding shutter 1 can be used particularly as sun protection or visual protection or for the protection of the wind and bad weather as well as for protection against theft.

The sliding folding shutter 1 has a first blind element 10, which is pivotally supported in the area of its first lateral edge 11 around a first non-movable vertical main axis 51, which is in a closing plane 3 which extends vertically, as illustrated in Fig. 3. The first main axis 51 must be understood - like the other main axes - as a geometric axis. Preferably, however, it may also be a mechanical shaft, for example the pin of a hinge fixed to the second lateral edge 11. The first main axis 51 constitutes the tiltable joint between the first blind element 10 and the opening frame. of the building, for example the window frame.

In general, it should be understood under the first lateral edges that lateral edge of the blind element that in the open state, that is in the folded state as an accordion of the sliding folding blind, shows towards the opening of the building and towards the main axes, while under the second side edges the other side edge, located on the opposite side of the blind element and showing outside the opening of the building and towards the auxiliary axis, should be understood.

A second blind element 20 is pivotally linked, in the area of its second lateral edge 22, with the first blind element 10 in the area of the second lateral edge 12 thereof and around a first vertical auxiliary axis 61. At as in the main axes it is also treated in the auxiliary axes of geometric axes, but they can also be constituted by physical axes, particularly by hinge elements, as can be seen in Figs. 1 and 2.

The second blind element 20 is in turn pivotally supported in the area of its first lateral edge 21 around a second movable vertical main axis 52, which is in the closing plane 3. The second main axis 52 is guided linearly displaceable, by means of a first main guide element 56, along a closing axis 4 that extends horizontally perpendicular to the second vertical main axis 52 and in the closing plane 3. In other words, the first main axis 51 and the second main axis 52 are parallel and are in the closing plane 3 that extends vertically, the separation between both parallel main axes 51 and 52 being varied by moving the second main axis 52 in the direction of the closing axis Four.

Horizontally in the marginal area of the sliding folding shutter 1 and parallel to the closing axis 4 there is at least one main guide rail 80, in which the first main guide element 56 is linearly movable. Said first element of main guide 56 is arranged, in the area of the second main axis 52, particularly in the upper and / or lower edge of the second blind element 20. In the illustrated embodiment the second main axis 52 essentially passes through the main guide element 56, so in the plan view of Figs. 3 to 4e the first main guide element 56 is not graphically separable from the second main axis 52. The first main guide element 56 is for example a first sheave within the main guide rail 80, which simply enables mobility parallel to the axis. of closing 4 and around the second vertical main axis 52.

With the first main guide element 56 a main drive 81 is directly or indirectly coupled such that the first main guide element 56 can be moved linearly along the closing axis 4. The coupling can be produced directly for example by means of a belt drive inside the main guide rail 80, or indirectly, by the fact that for example a further, particularly third blind element 30 and / or fourth blind element 40, which is directly or indirectly linked to the second blind element 20, can be adjusted by means of the main drive 81 and therefore, when bumping the respective blind elements, adjust the first main guide element 56 at the same time, as is the case in the illustrated embodiment.

It is noted that the invention also comprises a sliding sliding shutter with only two blind elements 10 and 20, although the exemplary embodiment shown presents in total four blind elements 10, 20, 30 and 40. The third blind element 30 and the fourth blind element 40, which are described below, as well as the features arranged there and associated with these blind elements are optional features, which constitute a further embodiment of the invention.

Thanks to the displacement achieved directly or indirectly of the first main guide element 56 along the closing axis 4 it is possible to close the first blind element 10 as well as the second blind element 20 from a first open position O1, illustrated in Figs. . 3, 4d and 4e, in which the first blind element 10 and the second blind element 20 are folded in accordion form and are tilted out of the closing plane 3, to a first closed position C1, illustrated in Fig. 4a, in which the first blind element 10 and the second blind element 20 are deployed and tilted respectively towards the closing plane 3, and open them in reverse sequence, as illustrated in Figs. 4b and 4c.

In the first closed position C1, illustrated in Fig. 4a, of the two blind elements 10 and 20, these are according to the invention in a neutral alignment zone.

In the first closed position C1 are the first blind element 10 and the second blind element 20 aligned essentially parallel to the closing plane 3. In the illustrated embodiment example, the blind elements 10 and 20 are located in an alignment of on neutral, since the first main axis 51, the second main axis 52 and the first auxiliary axis 61 are arranged such that the first auxiliary axis 61 extends in the first closed position C1 and - with parallel alignment of the first element of blind 10 and of the second blind element 20 with respect to the closing plane 3 - outside the closing plane 3 on one side of the closing plane 3, and in the first open position O1 on the other side of the closing plane 3. In other words, the first auxiliary axis 61 is in the first closed position C1, Fig. 4a, on one side of the closing plane 3 and in the first open position O1, Figs. 3 and 4e, on the other side of the closing plane 3. Therefore, the first auxiliary axis 61 must be moved, to open and close, through the closing planes 3.

The state in which the first auxiliary axis 61 is essentially in the closing plane 3 and therefore the three axes 51, 52 and 61 all extend in the closing plane 3 is designated as absolute dead center alignment T, such as illustrated in Fig. 4b. In this state it is not possible to open the blind elements 10 and 20 only by linear displacement of the first main guide element 56 in the direction towards the first main axis 51, so that there is a labile balance based on the planar alignment of the three axes 51, 52 and 61. The absolute neutral alignment T can be achieved by separating the two main axes 51 and 52 from one another and thereby maximizing the separation between the main axes 51 and 52, as illustrated in Figs. 4a and 4b. This maximization is particularly achieved by linear displacement of the main guide element 56 in the direction outside the first main axis 51 by the main drive 81. Due to friction this alignment of absolute dead center T is surrounded by an area in which a blocking of the blind elements 10 and 20 and folding is not possible by linear displacement. This zone is designated the neutral alignment zone. Therefore, the neutral alignment zone is determined not only by the position of the auxiliary axis with respect to the closing plane, but also by friction in the joints and the hinge geometry. In other words, the neutral alignment zone is that alignment zone in which a pair of deployed blind elements that are in the vicinity of or in the closed position cannot, following the position of the auxiliary axis with respect to to the two main axes, be folded in accordion form by decreasing the distance between both main axes. This deadlock alignment zone is constituted, on the one hand, by the absolute deadlock alignment T, the area surrounding said absolute deadlock alignment T, resulting from friction, as well as from an eventual alignment point area. dead.

Depending on the type of arrangement of the axes in the blind elements, the closed position and the absolute neutral alignment coincide or, as in the example of the illustrated embodiment, they are separated, particularly with an over-point alignment zone. dead ready in between.

In the illustrated exemplary embodiment, the first blind element 10 and the second blind element 20 are aligned in the first closed position C1 essentially parallel to the closing plane 3 and are in alignment with a neutral position, as illustrated in Fig. 4a.

According to the invention, the sliding folding shutter 1 comprises an actuation unit 70 for overcoming the neutral alignment zone, which is arranged in the area of the first main axis 51. Preferably, the actuation unit 70 is located in the horizontal frame 2, which extends in the marginal area of the sliding folding shutter 1 and of the opening to be sealed and in a direction parallel to the closing axis 4. The actuation unit 70 has an actuator arm 71, capable of being displaced by an actuator motor 72, particularly tiltable about a tilt axis 73, as illustrated in Fig. 1. In the illustrated embodiment, the axis of rotation of the actuator motor 72 corresponds to the tilt axis 73 of the actuator arm 71. However, it is also possible to provide a reducer or other type of diverter element between the actuator motor 72 and the actuator arm 71, so that the motor displacement axis a The actuator motor 72 does not correspond to the tilting axis 73. The actuator motor 72 may be particularly constituted by a rotary drive or a linear drive, where appropriate a deviation element is used to generate a tilting movement, a linear movement or any other movement of the actuator arm 71 particularly around actuator shaft 73.

In the first blind element 10, an actuator stop 74 is arranged on the side 13 facing the horizontal frame 2, as illustrated in Fig. 2. In the illustrated exemplary embodiment said actuator stop 74 is an actuator pin. At least in the neutral alignment zone of the first blind element 10, the actuator stop 74 is located in the mechanical operability zone of the actuator arm 71, so that the actuator arm 71 can exert a force on the actuator stop 74 the initiation of a displacement of the first blind element 10.

In the illustrated embodiment, the actuator stop is configured as an actuator pin 74 which extends essentially parallel to the first main axis 51. However, another configuration is also possible, for example in the form of a nose, a hook or any other part extending into the mechanical operability zone of the actuator arm 71.

The actuation unit 70 and the actuator stop 74 are arranged and configured such that the actuator stop 74 is capable of being pressed into the operating zone by a movement generated by the actuator motor 72, in the embodiment example illustrated a swing, of the actuator arm 71 in a closing direction, particularly a closing swing direction, by the actuator arm 71 to the first closed position C1, as illustrated in Fig. 4a, and if pressed by a particularly opposite movement, in the exemplary embodiment illustrated a tilting, of the actuator arm 71 in an opening direction, particularly an opening tilting direction, by the actuator arm 71 outside the neutral alignment area, Figs. 4a and 4b, and in the direction of the first open position O1, Figs. 4c, 4d and 4e.

Preferably, the actuation unit 70 is realized in such a way that the actuator arm 71 contacts the actuator stop 74, during the movement in the closing direction, on one side facing the first open position O1 and, during the movement in the direction of opening, on the opposite side, facing the first closed position C1. In other words, the actuator arm 71 swings around the actuator stop 74 and contacts it from either side.

In addition, collection means are provided by means of which a position of the first blind element 10 in the neutral alignment zone, as illustrated in Figs. 4a and 4b. The collection means for capturing a position of the first blind element 10 in the neutral alignment zone, particularly in the absolute dead alignment alignment, are made in the exemplary embodiment illustrated as means for capturing an increase of the driving force of the main drive 81, particularly as means of capturing the increase in intensity in the main drive 81. In other words, a position of the first blind element 10 in the neutral alignment zone is captured by the fact that the main drive 81 is blocked, since a linear displacement of the blind elements 10 and 20 is no longer possible. In this state the blind elements 10 and 20 are found, for example, in the first closed position C1 in Fig. 4a. Since both blind elements 10 and 20 are in alignment with the neutral position, it is not possible to open the blind elements 10 and 20 by direct or indirect graduation of the first main guide element 56 towards the first main axis 51 The main drive 81 is locked. However, in this first closed position C1, Fig. 4a, it is possible to adjust the blind elements 10 and 20 from the first closed position C1 and the alignment of the neutral position to the alignment of the absolute dead point T, Fig. 4b, by graduating through the main drive 81 the first main guide element 56 outside the first main axis 51, until the two blind elements 10 and 20 adopt the absolute dead center alignment T. In this absolute dead center alignment T returns to the main drive 81 is locked and an increase in force occurs, which is particularly detectable by means of picking up the intensity increase in the main drive 81.

Once the neutral alignment zone has been abandoned, the blind elements 10 and 20 are again linearly movable in the corresponding direction. The collection means for capturing the abandonment of the neutral alignment zone are correspondingly realized, in the illustrated embodiment example, as means for capturing a decrease in the driving force of the main drive 81, particularly as means of pick-up of the decrease in intensity in the main drive 81.

However, the collection means may also be constituted by other suitable means. They can, for example, be constituted as a position sensor, microswitch, Hall sensor, light barrier, timer, half intensity sensor in the main drive or half intensity sensor in the actuator motor. Particularly it is possible to capture the position of the blind elements by means of a measurement of time. From the knowledge of the travel speed of the main drive 81 as well as the starting position and the kinematics of the blind elements 10 and 20 its position can be derived by time measurement.

The sliding folding shutter 1 according to the invention further comprises a steering unit 90, Fig. 4a, which is in such an operative connection with the main drive 81, the actuator motor 72 and the pick-up means and is configured such that in the first closed position C1, Fig. 4a, an opening sequence is executable and in the first open position O1, Figs. 4d and 4e, particularly an overall closed position O of the sliding folding shutter 1, Fig. 4e, a closing sequence can be executed.

In the opening sequence, the actuation unit 70 for tilting the first blind element 10 outside the neutral alignment zone, Figs. 4a and 4b, so that the two blind elements 10 and 20 leave the neutral alignment zone and are movable by the main drive 81. At least after leaving the neutral alignment zone, a steering of the drive occurs. main 81 for direct or indirect linear displacement of the first main guide element 56 in the direction towards the first main axis 51 to the first open position O1, Figs. 4c and 4d, particularly to a global open position O of the sliding folding shutter 1, Fig. 4e. The closing sequence is executable with the first open position O1, Figs. 4d and 4e, particularly an overall open position O of the sliding folding shutter 1, Fig. 4e. In the closing sequence, the main drive 81 is controlled for the direct or indirect linear displacement of the first main guide element 56 in the direction of the first closed position C1 and separating from the first main axis 51, as illustrated in Fig. 4c . Upon reaching the neutral alignment zone, in which a further linear displacement is no longer possible, particularly when the absolute dead alignment alignment according to Fig. 2b is reached, the actuation unit 70 for tilting is governed. from the first blind element 10 to the first closed position C1, Fig. 4a, possibly supported by a reversal of the main drive 81.

The steering unit 90 is preferably an electronic government, electrically linked to the main drive 81, the actuator motor 72 and the collection means. If the pick-up means for capturing a position of the first blind element 10 in the neutral alignment zone, particularly in the absolute dead-end alignment, are constituted by means of picking up an increase in intensity in the main drive 81, the collection means may be integrated in the steering unit in the form of an intensity measuring device. Instead of an electronic government unit 90, a pneumatic, hydraulic or mechanical government is also possible.

In accordance with a further embodiment of the invention the actuation unit 70, the actuator stop 74 and the steering unit 90 are arranged and made such that the actuator arm 71 is tiltable to a base position so separated from the actuator stop 74 that the first blind element 10 is freely tiltable decoupled from the actuation unit 70, as is the case in Figs. 4c, 4d and 4e.

In the embodiment illustrated in the drawings, to which the invention is not limited, the first main axis 51, the second main axis 52 and the first auxiliary axis 61 are arranged such that the first auxiliary axis 61 extends, in the first closed position C1 and with parallel alignment of the first blind element 10 and the second blind element 20 with respect to the closing plane 3, outside the closing plane 3 on one side of the closing plane 3 and therefore in alignment of on neutral, Fig. 4a, and in the first open position O1 on the other side of the closing plane 3, Figs. 4c, 4d and 4e. The steering unit 90 is then in such operative connection with the main drive 81, the actuator motor 72 and the pick-up means and is configured such that in the first closed position C1 an extended opening sequence is executable. In this enlarged opening sequence, which part of Fig. 4a, the main drive 81 is first governed for the direct or indirect linear displacement of the first main guide element 56 separating from the first main axis 51 to overcome the alignment of the neutral position. and to achieve an absolute dead center alignment T of the first blind element 10 and the second blind element 20. In this deadlock alignment T-illustrated in Fig. 4b -the first auxiliary axis 61 is essentially in the plane of closing 3. Now there is a government of the actuation unit 70 for the displacement -in the exemplary embodiment illustrated for the tilting of the first blind element 10 outside the alignment of absolute dead center T and of the alignment zone of Deadpoint. The main drive 81 is then governed for the direct or indirect linear displacement of the first main guide element 56 in the direction of the first main axis 51 to the first open position O1, Fig. 4d, particularly to a global open position O of the sliding folding shutter 1, Fig. 4e. This extended sequence is particularly advantageous in arrangements of sliding folding shutters that in the closed state are in alignment with neutral, as is the case in the illustrated embodiment, since the actuation unit 70 is unloaded and only has to act in a very small area, specifically the area near the alignment of absolute deadlock. However, according to the invention it is also possible to dispense with the described extended opening sequence even in an alignment blind over deadlock and that the actuation unit 70 is also responsible for the movement of the first blind element 10 in the area of alignment of neutral position in the direction of the alignment of absolute neutral. For this, the blind elements 10 and 20 should have, in the direction outside the first main axis 51, a corresponding clearance, so that a graduation towards the alignment of absolute neutral is not prevented by the main drive 81.

While until now essentially only the first two blind elements 10 and 20 have been considered, since the invention basically starts with two blind elements, there is of course also the possibility of expanding the blind elements in subsequent blind elements. These may be equipped, in correspondence with the first two blind elements, with a corresponding actuation unit 70 or have a simpler construction, which also has features in accordance with the present invention, as will be described below and also in the following drawings.

The sliding folding shutter 1 illustrated further comprises a third blind element 30, which in the area of its first lateral edge 31 is pivotally linked around the second movable vertical main axis 52 with the second blind element 20 in the area of the first lateral edge 21 of this. A fourth blind element 40 is pivotably linked around a second vertical auxiliary axis 62 in the area of its second lateral edge 42 with the third blind element 30 in the area of the second lateral edge 32 thereof. The fourth blind element 40 is pivotally supported, in the area of its first lateral edge 41, around a third movable vertical main axis 53, which is in the closing plane 3. The third main axis 53 is guided by linearly movable shape, by means of a second main guide element 57, particularly in the main guide rail 80, along the horizontal closing axis 4 extending perpendicularly to the third main axis 53 and in the closing plane 3, so that the horizontal separation between the second main axis 52 and the third main axis 53 is adjustable. In the illustrated embodiment, the third main axis 53 passes through the second main guide element 57, so that in the plan view, Fig. 3, the second main guide element 57 is not graphically separable from the third main axis 53 The main axes and vertical auxiliary axes 51, 52, 53, 61 and 62 are parallel to each other, the main axes 51, 52 and 53 being found in the closing plane 3.

The main drive 81 is directly or indirectly coupled in such a way, for example by a belt drive, with the second main guide element 57 that the third blind element 30 and the fourth blind element 40 are sealed, from a second position Open O2, Fig. 4e, in which the third blind element 30 and the fourth blind element 40 are folded together in accordion form and are tilted out of the closing plane 3, to a second closed position C2, Figs. 4c, 4b and 4a, in which the third blind element 30 and the fourth blind element 40 are deployed and tilted respectively towards the closing plane 3, by direct or indirect linear displacement of the second main guide element 57 along of the closing shaft 4, particularly by the main drive 81, and capable of being opened in reverse succession.

The sliding folding shutter 1b is in this case configured in such a way that it is capable of being closed, by linear displacement of the second main guide element 57, from a global open position O, Fig. 4e, with a first open position O1 and a second open position O2, so that the opening of the building is released, through a global intermediate position I, Figs. 4c and 4d, with a first open position O1 and a second closed position C2, to a global closed position C, Fig. 4a, with a first closed position C1 and a second closed position C2, so that the building opening is closed , and of being opened in reverse succession.

In the second closed position C2, in which the second auxiliary axis 62 is essentially in the closing plane 3 and / or, as is the case in the exemplary embodiment illustrated in Fig. 4a, the third blind element 30 and the fourth blind element 40 are in alignment essentially parallel to the closing plane 3, the third blind element 30 and the fourth blind element 40 are also in a neutral alignment area. In the exemplified embodiment, they are even in alignment with a neutral position, as can be seen from the position of axes 52, 62 and 53.

A first stop 76, particularly a first pin, is arranged in the third blind element 30 or - as is the case in the illustrated embodiment example - in the fourth blind element 40 on the side 13 oriented towards the horizontal frame 2 This first stop 76 is particularly a pin that extends parallel to the main axes 51, 52 and 53. In the horizontal frame 2 a first stop cam 77 is arranged so that the first stop 76 is guided in the area of neutral alignment of the third blind element 30 and of the fourth blind element 40 in the direction of the second closed position C2 by said first stop cam 77, so that during the linear displacement of the second main guide element 57 the respective blind element 30 or 40 is pressed perpendicular to the closing plane 3 towards the second closed position, as illustrated by the transition from Fig. 4d to Fig. 4c. The first stop cam 77 is particularly made as a cuff, whose cuff surface oriented towards the closing plane 3 guides the first stop 76 in the direction towards the closing plane 3 or towards the second closed position C2.

Furthermore, a second stop 78, particularly a second pin, is arranged on the third blind element 30 as is the case in the illustrated embodiment or on the fourth blind element 40 on the face 13 oriented towards the horizontal frame 2. The second stop 78 may correspond to the first stop 76. A second stop cam 79 is arranged in such a way in the horizontal frame 2 and is configured such that the second stop 76 is guided in the neutral alignment zone of the third blind element 30 or fourth blind element 40, respectively, outside the neutral alignment zone and in the direction of the second open position O2 by the second stop cam 79, so that when the second element of the linear movement moves main guide 57 towards the first main axis 51 the respective blind element 30 or 40 is pressed perpendicular to the closing plane 3 and out of the closing plane 3 from and the second closed position C2, as illustrated by the transition from Fig. 4c to Fig. 4d. Also, the second stop cam 79 is made particularly as a wedge, whose bowl surface oriented outside the closing plane 3 guides the second stop 78 in the direction outside the closing plane 3 and the neutral alignment zone.

An advantage of the invention consists in that the blind elements 10 to 40 can be aligned, in the global closing position C, parallel to each other and located in a plane, since it is thanks to the drive system according to the invention, which can be arranged in a covered manner in the horizontal frame 2, it is possible to overcome the neutral and an alignment of the neutral. A further advantage of the invention is that an alignment of the neutral position in the closed position is even possible, whereby the blind elements can be tensioned together in a protective manner against theft, so that a manual folding of the elements of blind is not possible or only with difficulties. Thanks to the mutual tensioning of the blind elements in the alignment of the neutral position, a wave of the blind elements is also prevented under the effect of the wind.

In addition to the exemplary embodiment illustrated, it is also possible to combine different individual, optional features, according to the invention.
