Abstract

The shutter (1) has a main drive (81) controlled for direct or indirect linear displacement of a main guiding member (56) towards a main axis in an opening position i.e. overall opening position, of the shutter. A closing sequence is enabled during the opening position of the shutter, and the main drive is directly or indirectly and linearly displaced toward a closed position and away from the main axis. An engaging unit (70) is controlled in the closed position when a dead center adjusting region is pivoted towards charging elements (10).

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 in front of windows and doors. 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 together like an accordion 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 for reasons of space.

In order to allow 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 the dead center or over-center position, the first store element and the second store element being flat or parallel to the closing plane, and an engaging unit located in the peripheral area of the push-fold store extending horizontal frame is arranged and with an engaging arm, which is pivotable about a pivot axis by means of an engagement motor to overcome the dead center alignment area. The further opening the pair of store takes place by a linear displacement of a main guide member by means of a main drive, the pair of stores from the edge region of Totpunktausrichtungsbereich in which the pair of shops unfolded and hinged to the closing plane, in a first open position in which the pair of shops folded accordion-like and pivoted away from the closing plane, is pivotable. The closing takes place in reverse order.

Furthermore, the sliding folding shutter comprises a control unit which is in operative connection with the main drive, the engagement motor and detection means for detecting the position of the pair of trays in the dead center alignment area and is designed such that an opening sequence and a closing sequence can be executed when the pair of trays are closed. In the opening sequence - when the loading pair is closed - the engagement unit for pivoting the pair of trays is actuated out of the dead-center alignment area. Simultaneously or subsequently, the main drive is driven to linearly displace the main guide member in the direction of the fixed main axis of the pair of trays and into the first open position. In the closing sequence - when the loading pair is in the open position - the main drive is driven to move the main guide member linearly in the direction of the fixed main axis of the pair of trays and in the direction away from the closed position. Upon reaching the Totpunktausrichtungsbereichs a driving of the engagement unit for pivoting the pair of trays takes place in the closed position.

In a further development of the invention, the store pair is guided such that it is in its closed position in a Übertotpunktausrichtung. Instead of the above-described opening sequence according to the invention a extended opening sequence are used in which the main drive is first controlled for linear displacement of the main guide member in the direction away from the fixed main axis of the pair of trays to overcome the Übertotpunktausrichtung and to achieve an absolute dead center of the pair of trays. In this absolute dead center alignment, the engagement unit is now activated for pivoting the pair of stores out of the absolute dead center alignment and the dead center alignment area. Following the main drive for linear displacement of the main guide member is driven in the direction of the fixed main axis in the open position.

According to the invention, the main drive and the engagement unit cooperate in such a way that the main drive in the pivot range of the store pair outside the dead center alignment area takes over the opening and closing of the store pair by the linear displacement of the main guide member, whereas the engagement unit, the pivoting of the store pair within the dead center and beyond in this allows by means of a pivoting movement. Thus, the advantages of a linear drive, namely its inconspicuous and integrable housing this powerful drive, with the advantages of a rotary actuator, which allows Totpunktüberwindung the pair of shops, connected. The disadvantages of both drive concepts, namely the inability of Totpunktüberwindung the linear drive and the conspicuous additional elements, especially a large-sized swivel arm, the pivot drive, does not have the drive concept of the sliding folding-loading invention, since a small-sized and acting only in Totpunktausrichtungsbereich pivot drive for Dead center overcoming must be used.

The invention thus makes it possible to realize a just-oriented in the closed state and located in dead center or even in Übertotpunktausrichtung sliding folding store, with disturbing and visually striking additional elements, which adversely affect the aesthetics of the sliding folding store and the susceptibility increase, can be waived.

In the following, the invention will be described with reference to a concrete embodiment with the aid of schematic illustrations, both in general and in particular purely by way of example, wherein further details of the invention and its advantages will be discussed. In detail show:

The FIGS. 1 to 4e show a common embodiment, which is why the mating figures are described in part together and to the re-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. In particular, a large thickness of the store elements was selected for better visibility of the side edges.

The FIGS. 1 and 2 and FIGS. 3 to 4e show, in a schematic side or oblique view and top view, respectively, a sliding folding shutter 1 for closing and releasing at least part of a building opening, in particular a window or a door. The sliding folding shutter 1 can be used in particular for sun or privacy or for wind and weather protection and burglary protection.

The sliding folding shutter 1 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 lies in a vertically extending closing plane 3, as in FIG. 3 shown. The first Main axis 51 is - 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.

In the region of its second side edge 22, a second loading element 20 is pivotally connected to the first loading element 10 in the region of its second side edge 12 about a vertical first secondary 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, as in the FIGS. 1 and 2 recognizable.

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 linearly displaceable along a perpendicular to the vertical second main axis 52 and in the closing plane 3 horizontal locking axis 4 by means of a first main guide member. In 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 4.

Horizontally in the edge region of the sliding folding tray 1 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 on the upper and / or lower edge of the second loading element 20. In the embodiment shown, the second main axis 52 passes substantially through the main guide member 56, which is why in the plan view of FIGS. 3 to 4e 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 allows only a movement parallel to the locking axis 4 and around the vertical second main 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, in particular third loading element 30 and / or fourth loading element 40, which is directly or indirectly connected to the second loading element 20, adjustable by means of the main drive 81 is and thus at stop the respective first store element 56 mitverstellt the first main guide member 56, as in the embodiment shown the case.

It should be noted that the invention also includes a sliding folding shutter with only two shutter elements 10 and 20, even though the illustrated embodiment has a total of four shutter elements 10, 20, 30 and 40. The third store element 30 and the fourth store element 40 described below and the features arranged there and associated with these store elements are optional features which represent a development of the invention.

By directly or indirectly forced displacement of the first main guide member 56 along the locking axis 4, it is possible, the first shutter member 10 and the second shutter member 20 of a in the Figures 3 . 4d and 4e 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 FIG. 4a shown 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 Figures 4b and 4c shown.

In the in FIG. 4a shown first closed position C1 of the two store elements 10 and 20 are selbige according to the invention in a Totpunktausrichtungsbereich. In the first closed position C1, the first loading element 10 and the second loading element 20 are each aligned substantially parallel to the closing plane 3. In the exemplary embodiment shown, the store elements 10 and 20 are located in an over-center orientation, since the first main axis 51, the second main axis 52 and the first minor axis 61 are arranged such that the first minor axis 61 in the first closed position C1 and with parallel alignment of the first loading element 10 and the second loading element 20 to the closing plane 3 - extends 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 minor axis 61 is in the first closed position C1, FIG. 4a on the one side of the closing plane 3 and in the first open position O1, Figures 3 and 4e , on the other side of the closing plane 3. The first minor axis 61 must therefore be guided through the closing levels 3 for opening and closing.

The state in which the first minor axis 61 lies substantially in the closing plane 3, and thus the three axes 51, 52 and 61 all run in the closing plane 3, is referred to as absolute dead center orientation T, as in FIG FIG. 4b shown, designated. In this state, it is not possible to open the shutter members 10 and 20 only by linearly displacing the first main guide member 56 toward the first main shaft 51, which has an unstable balance due to the planar alignment of the three shafts 51, 52 and 61. The absolute dead center alignment T can be achieved by pulling the two main axes 51 and 52 apart and thus maximizing the spacing of the major axes 51 and 52, as in FIGS FIGS. 4a and 4b shown. This maximizing is achieved in particular by linear displacement of the main guide member 56 in the direction away from the first main axis 51 by means of the main drive 81. Due to friction, this absolute dead center orientation T is surrounded by a region in which blocking of the loading elements 10 and 20 likewise takes place and folding is not possible by linear displacement. This area is called the dead center alignment area. The dead center alignment range is thus 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. In other words, the dead point alignment area is that alignment area in which a close-up unfolded pair of store elements can not be accordion-folded by reducing the pitch of the two major axes due to the location of the minor axis relative to the two major axes. This dead center alignment area is formed on the one hand by the absolute dead center orientation T, the area surrounding this absolute dead center T, which results from friction, and a possible overcenter alignment area.

Depending on the nature of the arrangement of the axes on the shutter elements, the closed position and the absolute dead center alignment coincide or, as in the illustrated embodiment, they are apart, in particular with the over-center alignment area therebetween.

In the exemplary embodiment shown, 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 and are in over-center alignment, as in FIG FIG. 4a shown.

According to the invention, the sliding folding shutter 1 has an engagement unit 70 for overcoming the dead center alignment area, which is arranged in the region of the first main axis 51. Preferably, the engagement unit 70 is located on the horizontal frame 2, which is in the edge region of the sliding folding store 1 and the opening to be closed and parallel to the closing axis 4. The engagement unit 70 has an engagement arm 71, which is movable by means of an engagement motor 72, in particular pivotable about a pivot axis 73, as in FIG FIG. 1 shown. In the illustrated embodiment, the rotational axis of the engagement motor 72 corresponds to the pivot axis 73 of the engagement arm 71. However, it is also possible to provide a transmission or other deflection between the engagement motor 72 and the engagement arm 71, so that the axis of movement of the engagement motor 72 does not correspond to the pivot axis 73 , The engagement motor 72 can be formed, in particular, by a rotary drive or a linear drive, with optionally a deflecting member being used to generate a pivoting movement, a linear movement or another movement of the engagement arm 71, in particular around the engagement axis 73.

On the first loading element 10, an engagement stop 74 is disposed on the side facing the horizontal frame 2 side 13, as in FIG. 2 illustrated. In the embodiment shown, the engagement stop 74 is an engagement bolt. At least in the dead center alignment area of the first loading element 10, the engagement stop 74 is in the mechanical working area of the engagement arm 71 so that the engagement arm 71 can exert a force on the engagement stop 74 to initiate movement of the first loading element 10.

In the exemplary embodiment shown, the engagement stop is designed as an engagement bolt 74 extending substantially parallel to the first main axis 51. However, it is also another embodiment, for example in the form of a nose, a hook or any other part that extends in the mechanical action region of the engagement arm 71, possible.

The engagement unit 70 and the engagement stop 74 are arranged and configured such that the engagement stop 74 in the effective region by a forced by the engagement motor 72 moving, in the illustrated embodiment pivoting, the engagement arm 71 in a closing direction, in particular a closing pivot direction of the Engaging arm 71 in the first closed position C1, as in FIG. 4a is shown, can be pressed and by a particular opposite movement, in the illustrated embodiment pivoting, the engagement arm 71 in an opening direction, in particular an opening pivoting direction, of the engagement arm 71 from the dead center alignment area, FIGS. 4a and 4b , out and towards the first open position O1, Figures 4c, 4d and 4e , is depressible.

Preferably, the engagement unit 70 is formed such that the engagement arm 71 contacts the engagement stop 74 when moving in the closing direction on a side facing the first open position O1 and moving in the opening direction on an opposite side facing the first closed position C1 , In other words, the engagement arm 71 pivots about the engagement stop 74 and contacts it either from one side or the other.

In addition, detecting means are provided, by means of which a position of the first loading element 10 in Totpunktausrichtungsbereich, as in the FIGS. 4a and 4b shown is detectable. The detection means for detecting a position of the first shutter member 10 in the dead center alignment area, particularly in the absolute dead center, in the illustrated embodiment, as a means for detecting a driving force increase of the main drive 81, in particular as Current increase detecting means formed on the main drive 81. In other words, a position of the first loading element 10 in the dead center alignment area is detected by the fact that the main drive 81 is blocked, since a linear displacement of the loading elements 10 and 20 is no longer possible. In this state, the store elements 10 and 20 are located, for example, in the first closed position C1 in FIG FIG. 4a , Since both store elements 10 and 20 are in over-center alignment, it is not possible to open the store elements 10 and 20 by directly or indirectly moving the first main guide member 56 in the direction of the first main axis 51. The main drive 81 blocked. However, in this first closed position, it is C1, FIG. 4a possible, the loading elements 10 and 20 from the first closed position C1 and the over-center orientation in the absolute dead center T, FIG. 4b to be adjusted by the main drive 81, the first main guide member 56 is moved away from the first main axis 51 until the two shutter elements 10 and 20 assume the absolute dead center T orientation. In this absolute dead center alignment T, the main drive 81 is again blocked and there is an increase in force, which can be detected in particular by current increase detection means on the main drive 81.

After leaving the Totpunktausrichtungsbereichs the store elements 10 and 20 are again linearly displaceable in the appropriate direction. The detecting means for detecting the leaving of the dead center alignment area are accordingly in the illustrated embodiment as a means for detecting a driving force drop of the main drive 81, in particular as a current drop detection means on the main drive 81, is formed.

However, the detection means may also be formed by other suitable means. They can be formed, for example, as a position sensor, microswitch, Hall sensor, light barrier, time switch, current detection means on the main drive or current detection means on the engagement motor. In particular, it is possible to detect the position of the store elements by a timekeeping. From the knowledge of the speed of movement of the main drive 81 and the starting position and the kinematics of the shutter elements 10 and 20, their position can be derived by timing.

The sliding folding shutter 1 according to the invention further comprises a control unit 90, FIG. 4a which is in operative connection with the main drive 81, the engagement motor 72 and the detection means and is designed such that in the first closed position C1, FIG. 4a , an opening sequence and at the first open position O1, Figures 4d and 4e , in particular an overall open position O of the sliding folding store 1, Figure 4e , a closing sequence is executable.

In the opening sequence, the engagement unit 70 turns out of the dead center alignment area for pivoting the first shutter 10. FIGS. 4a and 4b , so that the two loading elements 10 and 20 leave the dead center alignment area and are displaceable by means of the main drive 81. At least after leaving the dead center alignment area, the main drive 81 is actuated for direct or indirect linear displacement of the first main guide element 56 in the direction of the first main axis 51 into the first open position O1. Figures 4c and 4d , in particular in an overall open position O of the sliding folding store 1, Figure 4e , The closing sequence is at the first open position O1, Figures 4d and 4e , in particular an overall open position O of the sliding folding store 1, Figure 4e , executable. In the closing sequence, the main drive 81 is driven to directly or indirectly linearly displace the first main guide member 56 toward the first closed position C1 and away from the first main axis 51, as in FIG Figure 4c shown. Upon reaching the dead center alignment area, in which a further linear displacement is no longer possible, in particular when the absolute dead center alignment according to FIG. 2b is reached, the engagement unit 70 is actuated to pivot the first shutter element 10 into the first closed position C1, FIG. 4a possibly assisted by reversing the direction of the main drive 81.

The control unit 90 is preferably an electronic controller electrically connected to the main drive 81, the engagement motor 72 and the detection means. If the detection means for detecting a position of the first shutter element 10 in the dead center alignment area, in particular in the absolute dead center, formed by current increase detection means on the main drive 81, the detection means may be integrated in the form of a current measuring device in the control unit. Instead of an electronic control unit 90 also a pneumatic, hydraulic or mechanical control is possible.

In one development of the invention, the engagement unit 70, the engagement stop 74 and the control unit 90 are arranged and configured such that the engagement arm 71 is pivotable into a basic position pivoted away from the engagement stop 74 in such a way that the first loading element 10 is freely pivotable from the engagement unit 70 is like in the Figures 4c, 4d and 4e the case.

In the embodiment shown in the figures, to which the invention is not limited, the first main axis 51, the second main axis 52 and the first minor axis 61 are arranged such that the first minor axis 61 in the first closed position C1 and in parallel alignment of the first Store element 10 and the second loading element 20 to the closing plane 3 outside the closing plane 3 on the one side of the closing plane 3 and thus in the over-center position, FIG. 4a , and in the first open position O1 on the other side of the closing plane 3, Figures 4c, 4d and 4e runs. The control unit 90 is in this case in operative connection with the main drive 81, the engagement motor 72 and the detection means and is designed such that in the first closed position C1 an extended opening sequence can be executed. In this extended opening sequence, by FIG. 4a Initially, the main drive 81 for direct or indirect linear displacement of the first main guide member 56 in the direction away from the first main axis 51 to overcome the Übertotpunktausrichtung and to achieve an absolute dead center T of the first loading element 10 and the second loading element 20 is driven. In this - in FIG. 4b In the embodiment shown for pivoting, the first loading element 10 is moved out of the absolute dead center alignment T and the dead center alignment area. Subsequently, the main drive 81 for direct or indirect linear displacement of the first main guide member 56 in the direction of the first main axis 51 in the first open position O1, FIG. 4d , in particular in an overall open position O of the sliding folding store 1, Figure 4e . driven. This extended sequence is particularly advantageous in sliding folding shutter assemblies that are in the over centered overclock position, as is the case in the embodiment shown, because the engagement unit 70 is unloaded and only in a very small area, namely the area near the absolute dead center, must work. According to the invention, however, it is also possible for the described extended opening sequence to be dispensed with even in the event of an over-center alignment loading and for the engagement unit 70 to also move the first loading element 10 in the over-center alignment area in the direction of absolute dead center alignment. For this purpose, the store elements 10 and 20 in the direction away from the first main axis 51 should have a corresponding clearance, so that an adjustment in the absolute dead center alignment is not prevented by the main drive 81.

While hitherto essentially only the first two store elements 10 and 20 have been discussed, since the invention initially starts from two store elements, it is of course also possible to extend the store elements by further store elements. These may be equipped with a corresponding engaging unit 70 according to the first two loading elements or may have a simpler construction which also has features according to the invention, as described below and also in the figures.

The sliding folding shutter 1 shown also has a third loading element 30 which is pivotally connected in the region of its first side edge 31 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 in the region of its second side edge 42 with the third Shop element 30 in the region of the second side edge 32 pivotally connected about a vertical second minor 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 main axis 53 is linearly displaceably guided along the horizontal closing axis 4 perpendicular to the third main axis 53 and in the closing plane 3 by means of a second main guide element 57, in particular in the main guide rail 80, 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 in plan view, FIG. 3 in that the second main guide member 56 is not graphically separable from the third main axis 53. 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 so directly or indirectly coupled, for example by means of a belt drive with the second main guide member 57, that the third shutter member 30 and the fourth shutter member 40 from a second open position 02, Figure 4e 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 4c, 4b and 4a in which the third loading element 30 and the fourth loading element 40 are unfolded and pivoted respectively 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 closed by means of the main drive 81 and in reverse order openable.
