The invention relates to a sliding folding shutter for closing and releasing at least a part of a window or door opening, with a peripheral first loading element, which in the region of its one side edge pivotable about a vertical, immovable axis between an open and a closed position is stored, a second loading-5 element which is pivotally connected in the region of its one side edge with the first shop element in the region of the other side edge and which is pivotally mounted in the region of its other side edge about a vertical, parallel to the wall plane guided axis a third loading element which is connected in the region of its one side edge to the second loading element, wherein it is in the region of this one side edge io about the vertical, displaceable axis about which the second loading element is pivotable, or about a distance from this axis vertical , parallel to the wall plane versch movably guided axis is pivotally mounted between an open and a closed position, and a fourth shop element, which is pivotally connected in the region of its one side edge pivotally connected to the third shop element in the region of the other side edge 15 and in the region of its other side edge a vertical, guided parallel to the wall plane guided axis is pivotally mounted.

Sliding-folding shutters are known in particular in two- and four-winged version. In the closed state of the sliding folding shutter, the individual shutter elements lie in a common plane in FIG. 20 and, optionally together with a second sliding shutter shutter, close the window or door opening in front of which they are arranged. In the open state of the sliding folding shutter this accordion-like folded and the individual, pivotally interconnected shop elements are substantially perpendicular to the wall plane, which has the window or door opening directed out 25. Here, the store elements, apart from the edge-side first shop element, which is only pivotally mounted, but not slidably mounted, in addition to their respective window or door opening facing edge sides parallel to the wall plane slidably mounted in horizontal guide rails. Usually, such sliding folding shutters are manually operated. For a two-leaf sliding-folding shutter of this kind, a drive device for automatically opening and closing the sliding-folding shutter has already become known. Hereby, a linear drive cooperates with the side edge of the second loading element guided pivotably and displaceably in the horizontal guide rails, in order to open and close the sliding folding shutter by shifting this side edge of the second loading element along the guide rails. A disadvantage of this conventional drive device is that it is relatively complicated. Furthermore, a fully aligned in a common plane alignment of the shutter elements in the closed state of the sliding-folding shutter in practice due to the limited suit-40 force of the drive motor can not be achieved. In a four-leaf sliding folding shutter, there would be an even greater severity of this problem.

In non-generic wing doors drive devices are known, which have a pivotable about a vertical axis by a drive motor pivot lever. 45

A folder door is known from WO 2004/074616 A1, wherein a drive device for opening and closing the motor is described, in which one of a drive motor pivotable about a vertical axis pivoted lever cooperates with the first wing element. From DE 35 13 630 C1 a folding door is known, wherein an inserted between the wings spring arrangement is disclosed.

The object of the invention is to provide an automatically openable and closable sliding folding shutter of the type mentioned, the drive device is simply ausgebil-det 55 and operates reliably and in the closed state in a common men in a 3-membered 502 827 B1 men Level orientation of the individual store elements can be achieved. This is achieved by a sliding folding shutter with the features of claim 1. 5 by the operation of the first loading element by means of a pivotable about a vertical pivot axis pivot lever and the third loading element by means of a pivotable about a vertical pivot axis additional pivot lever can be a very simple and reliably operating drive means of a sliding folding shutter of the type mentioned are provided. In the closed state of the sliding folding window io loading here the levels of the individual store elements can be made parallel by the drive means, so that they come to lie parallel to the wall plane.

In an advantageous embodiment of the invention, the pivot axis of the pivot lever from the vertical axis about which the first shutter member is pivotable, spaced and the cooperating engagement parts of the pivot lever and the first shutter member are mutually displaceable. By such a design, a conventionally formed manually operated sliding folding shutter can be equipped with a drive device according to the invention in a simple manner, without changes to the fittings of the shutter elements are required and wherein the conventional guide rails 20 can be used for the shutter elements.

Advantageously, the vertical axis of the third loading element and the pivot axis of the additional pivot lever are spaced apart from each other and the additional pivot lever and the third loading element have cooperating engagement parts which are against each other ver-25 pushed. When closing the shutter starting from its open state, the auxiliary pivot lever is initially wasted from its opening position to its closed position, whereby the third loading element and with it the fourth loading element are wasted in their closed positions. As a result, when the pivoting lever cooperating with the first loading element is wasted about its vertical pivoting axis from its open position to its closed position, thereby wasting the first loading element and the second loading element to their closed positions, the loading-element engaging part passes the third store element in this case out of engagement of the additional pivot lever engaging member and is guided in the sequence in a stationary longitudinal guide parallel to the wall plane displaceable, so that this additional pivot lever engaging part to-35 together with the third and fourth shop element can move parallel to the wall plane.

Further advantages and details of the invention are explained below with reference to the accompanying drawings. In this show: 40 Fig. 1

A sliding folding shutter system with a two-leaf and a four-leaf sliding-folding shutter according to an embodiment of the invention is shown in the figures. The four-leaf sliding folding shutter comprises the shutter elements 1 to 4. The edge-side first shutter element 1 is in the region of its one side edge 5 about a vertical, immovable axis between an open position (Fig. 1 to 11) and a closed Position (Fig. 12 to 18) pivotally mounted. For this purpose serve swivel fittings 14, which may be formed in a conventional manner. For example, the first store element 1 is connected via the swivel fittings 14 to a vertical frame profile 15 which is attached to the wall 17 having the window or door opening 16, which is indicated schematically only in FIGS. 2 and 5. The first shop element 1 could also be mounted in a different way with respect to the window or door opening 16 having wall 17 pivotable, but immovable. In the region of its other side edge 6, the first shop element 1 is pivotably connected about a vertical axis to a second shop element 2, in the region of its one side edge 7. Slewing fittings 18 serving for this purpose can be designed in a conventional manner. In the region of its other side edge 8, the second shutter element 2 is pivotably mounted about a vertical axis 20, which is displaceably guided parallel to the wall plane 19 (between an open position and a closed position). Serving for this purpose pivot sliding hardware 21 may be formed in a conventional manner and, for example, in horizontal frame sections 22, 23, the guide rails comprise, be guided horizontally and parallel to the wall plane 19 slidably. A third loading element 3 is connected in the region of its one side edge 9 to the second loading element 2, wherein it is pivotable about the vertical, displaceable axis 20 about which the second loading element 2 can pivot between an open position (FIGS. 1 to 6). and a closed position (FIGS. 7 to 18) is pivotably mounted. The second and the third shop element 2, 3 are thus also against each other about this vertical axis 20 pivot-40 bar. For example, the pivot slide fittings 21 serve both for the pivotable connection of the second and third loading element 2, 3 and for the pivotable and displaceable mounting of these two store elements 2, 3 with respect to the wall 17.

In the region of its other side edge 10, the third shop element is pivotally connected to the fourth shop element 4 pivotably about a vertical axis, in the region of its one side edge 11. Slewing fittings 24 serving for this purpose can be designed in a conventional manner. In the region of its other side edge 12, the fourth loading element 4 is pivotably mounted about a vertical axis guided displaceably parallel to the wall plane 19 (between an open position and a closed position). Serving for this so pivot sliding hardware 26 may be formed in a conventional manner and are guided, for example, in guide rails of horizontal frame profiles 22, 23 parallel to the wall plane 19 slidably.

The previously described parts of the sliding folding shutter are known. 55 5 AT 502 827 B1

The sliding folding shutter can be automatically opened and closed by a drive device. This drive device comprises a pivoting lever 27, which is pivotable about a vertical, fixed pivot axis 28 between an open position (FIGS. 1 to 11) and a closed position (FIGS. 12 to 18), namely by a drive motor 29 via 5 in the figures not shown in detail gear 30, which is designed here as an angle gear.

Preferably, the pivot bearing for the pivot lever 27 is rigidly connected to the upper horizontal frame profile 22. 10

When pivoting the pivot lever 27 from its opening into its closed position, the first shutter element 1 is pivoted about the vertical axis 13 from its open position to its closed position and vice versa. For this purpose, the pivot lever 27 and the first loading element 1 via engagement members 31, 32 are interconnected. Preferably, the pivot axis 28 of the pivoting lever 27 is spaced from the vertical axis 13 of the first loading element 1 (see, e.g., Fig. 5) and the cooperating engaging portions 31, 32 are slidable relative to each other in this case. For example, the loading element engagement member 31 is formed by a pin-like extension and the pivot lever engagement member 32 of a guide rail, in which engages the pin-like extension of the Ladenele-20 element 1. The guide rail can be formed by a downwardly open U-profile. The pin-like extension may also have a roller mounted about a vertical axis. When opening and closing the first loading element 1, the pin of the first loading element 1 shifts in the longitudinal direction of the guide rail. It would also be conceivable and possible to provide a guide rail on the first loading element 1, into which a pin-like extension 25 of the pivoting lever 27 engages.

When the first loading element 1 is pivoted between its open position and its closed position, the second loading element 2 is also pivoted between its open position and a closed position about its vertical axis 20, this vertical axis 20 being parallel to the plane of the wall 19 is pushed away from the vertical axis 13 of the first loading element 1.

In their closed positions, the first shop element 1 and the second shop element 2 are parallel to each other and parallel to the wall plane 19. In their open positions they are 35 approximately at right angles to the wall plane. Preferably, their planes enclose an angle of at least 3 ° with each other. The minimum angle which the store elements 1, 2 enclose with one another in their open positions is predetermined, for example, by stops 33, 34 which come into abutment when the store elements 1, 2 are opened. A stop could also be present for the second shutter element 2, which limit the displacement of the 40 side edge of the second shutter element 2 facing away from the first shutter element 1 in the direction of the first shutter element 1.

This minimal angle between the store elements 1, 2 ensures that the pivoting of the second store element 2 is made possible by the first store element 1 when it is closing 45 by the pivot lever 27. Instead or in addition, a spring element acting between the first and second loading elements 1, 2 in their open positions could also be provided, which is stretched in the open positions of the loading elements 1, 2 and in the sense of a pivoting apart of the two loading elements 1, 2 acts. In this case, it would also be conceivable and possible for the store elements 1, 2 to rest completely against one another in their open-50 positions, ie lie parallel to one another and at right angles to the wall plane 19.

Preferably, the transmission 30 is self-locking. The pivot lever 27 could also be blocked in other ways in its closed position when the drive motor 29 55 is not actuated. 6 AT 502 827 B1

The drive device further comprises an additional pivot lever 35, which is pivotable about a vertical, fixed pivot axis 36 between an open position (Fig. 1 to 6) and a closed position (Fig. 7 to 18), by a further drive motor 37. The drive takes place preferably via a in the figures only schematically illustrated gear 38, 5 which is formed here in the form of an angular gear.

The vertical pivot axis 36 of the additional pivot lever 35 is spaced in the longitudinal direction of the horizontal frame profile 22 from the pivot axis 28 of the pivot lever 27. Preferably, the pivot bearing of the auxiliary pivot lever 35 is rigidly connected to the upper horizontal frame profile 22.

When pivoting the additional pivot lever 35 between its open and closed positions - when the first and second shutter elements 1, 2 are in their open positions - the third shutter member 3 between its open and closed position ver-15 pivots. For this purpose, the additional pivoting lever 35 and the third loading element 3 have cooperating engagement parts 39, 40. These engaging parts 39, 40 can be disengaged in the closed position of the third loading element 3, as will be explained in more detail below. Preferably, the pivot axis 36 of the additional pivot lever 35 from the axis 20 about which the third shutter member 3 is pivotable, spaced and the engaging members 39, 40 move when opening and closing the third shutter member 3 against each other, as already in connection with the Engagement parts 31, 32 of the first loading element 1 and the pivot lever 27 has been described. For example, the loading-element-engaging member 39 may be formed in the form of a pin-like projection, which engages in the formed in the form of a guide rail additional pivot lever engagement member 40. This guide rail can be formed by a downwardly open U-profile. The peg-shaped extension may also have a rotatably mounted about a vertical axis roller. 30

When the third loading element 3 is pivoted between its open and closed position by the additional pivoting lever 35, the fourth loading element 4 also pivots about its vertical position between its open position (FIGS. 1 to 6) and its closed position (FIGS. 7 to 18) Axis 25, said vertical axis 25 is parallel to the wall plane 19 of 35 of the vertical axis 20, about which the third shutter member 3 is pivoted, is pushed away.

In their closed positions, the third and fourth shutter elements 3, 4 are parallel to each other and parallel to the wall plane 19. In their open positions they are approximately 40 perpendicular to the wall plane 19. To start from its open position, the pivoting of the fourth shutter member 4 in to allow its closed position by the third shop element 3 during its pivoting from its open position to its closed position by means of the additional pivot lever 35, close the third and fourth shop elements 3, 4 in their open positions a minimum angle of at least 3 ° one. This minimum angle is predetermined, for example, by stops 41, 42 which start when the loading elements 3, 4 are opened by the additional pivoting lever 35. Instead or in addition to this could (again as described above in connection with the first and second shop element) in the open positions of the third and fourth store elements 3, 4 tensioned and this acting in the sense of a swiveling apart spring-50 element be present. In this case, the store elements 3, 4 could also be completely in contact with each other in their open position, i. standing at right angles to the wall plane 19.

The transmission 38 of the additional pivot lever 35 is preferably self-locking. The auxiliary pivot lever 35 could also be blocked in its other way in its closed position 55, if it is not driven by the drive motor 37. 7 AT 502 827 B1

In the closed position of the additional pivot lever 35 this is parallel to the wall plane 19 and parallel to the longitudinal guide 43 forming guide rail which is open at its the auxiliary pivot lever 35 side facing and directly adjoins the guide rail, i. with only a small gap between them, so that the shop-element engaging part 39 5 is guided continuously parallel to the wall plane 19.

When the sliding folding shutter is to be closed, starting from its open state shown in FIGS. 1 to 6, the third and fourth shutter elements 3, 4 are first pivoted from their open position to their closed position by pivoting the auxiliary pivot lever 35 pivoted. This half-closed or half-opened state of the sliding folding shutter is shown in FIGS. 7 to 11. As a result, the first and second loading elements 1, 2 are pivoted by pivoting the pivot lever 27 from its open to its closed positions. Here, the third and fourth shutter members 3, 4 are moved by the connection of the third shutter member 3 with the second Lais denelement 2 parallel to the wall plane 19, in the direction away from the vertical axis 13 of the first shutter element 1 direction. Here, too, the shop-element engaging part 39 of the third shop element 3 shifts with respect to the auxiliary swiveling lever engaging part 40, and the two engaging parts 39, 40 are disengaged. In the embodiment shown, the shank-shaped engaging member formed by a peg-20 engaging member 39 is pushed out of the open end of the guide rail, which forms the additional pivot lever engaging member 40 and pushed into the adjacent open end of a stationary longitudinal guide 43, which also in the embodiment shown by a guide rail is formed, which is formed for example in the form of a downwardly open U-profile. The longitudinal guide 43 is preferably attached to the upper horizontal frame profile 22 25.

In the longitudinal guide 43, the loading element engagement part 39 is guided parallel to the wall plane 19. By this displacement of the shutter engaging part 39 guided in the longitudinal guide 43, the third and fourth shutter members 3, 4 are further held in their closed positions, i. a pivoting about their vertical axes 20, 25 is prevented and they are held in a parallel to each other and parallel to the wall plane 19 orientation.

During the displacement of the third and fourth loading element 3, 4 parallel to the wall plane 19 35, the pivot sliding hardware 21, 26 move in the guide rails of the frame profiles 22, 23rd

When the first and second shutter members 1, 2 are pivoted to their closed positions, the completely closed state of the sliding shutter shutter 40 shown in FIGS. 12 to 18 is now present.

The opening operation of the sliding-folding shutter proceeds in the reverse order, that is, in the reverse order. The first and second loading elements 1, 2 are first pivoted into their open positions by means of the pivoting lever 27, the third and fourth loading elements 3, 45 4 shifting parallel to the wall plane and the loading element engaging part 39 initially displacing in the longitudinal guide 43 and, in turn, engages the auxiliary pivot lever engagement member 40. As a result, the third and fourth shop element 3, 4 is pivoted by means of the additional pivot lever 35 in its open positions. Thus, in the embodiment shown, the sliding-folding system further comprises a two-leaf sliding-folding shutter, which in its opened state is arranged on the other side of the window or door opening 16. The first and second shutter elements 1, 2 of this two-leaf shutter are formed in a completely analogous manner as the first and second shutter elements 1, 2 of the four-leaf shutter described above. The drive device here comprises only the one cooperating with the first loading element 1, from 8 AT 502 827 B1

Drive motor 29 via the gear 30 driven first pivot lever 27. The driven auxiliary pivot lever 35 is omitted here.

The two sliding folding shutters of the embodiment shown are connected to each other via one of the vertical frame profiles 15 and the horizontal frame profiles 22, 23 formed by the circumferential frame. When closed, they each close a corresponding part of the window or door opening 16.

The sliding-folding system could also comprise only a single sliding-folding shutter which, when opened, is disposed on a side of the side of the window or door opening. For example, two four-leaf sliding folding shutters could also be present. Various modifications of the embodiment shown are conceivable and possible without departing from the scope of the invention. For example, it would be conceivable and possible in principle for the pivoting lever 27 and the additional pivoting lever 35 to provide a single drive motor 15, from which the two pivoting levers can be selectively driven.

The second and third loading elements 2, 3 could, for example, in the region of their interconnected side edges 8, 9 are also mounted so as to be pivotable about spaced vertical axes, which are guided displaceably parallel to the wall plane 19. 20

The shop-element engagement part 31 and the pivot lever engagement part 32 could also be designed in another way, in particular be designed to be displaceable relative to one another. The same applies to the shopper-engaging part 39 of the third shopper element 3 and the auxiliary pivoting lever engaging part 40. For example, it would be conceivable and possible to form the auxiliary pivoting-lever engaging part in the form of a pin formed in a guide rail forming the shopper-engaging part engages, which is rigidly attached to the third shop element. The longitudinal guide 43 could be formed in this case by a guide rail parallel to the wall plane 19 leading device, for example, by a guide channel between them enclosing guide rollers. 30
