Description

The invention relates to a Faltschiebeladen for a window or door element with more than one protective element, wherein the folding and unfolding is done by hand or motorized, and a method to achieve this.

Traditionally, it has been known to use shutters in the form of shutters. Since such shutters must be pivoted to open each sideways, to the right and left, they need on the one hand a considerable swing radius and on the other hand on the respective facade on which they are then kept in the open state, sufficient space.
With large and wide window fronts this space is not always available in sufficient measure and shutters are no longer reasonable to handle.

To remedy this situation, shutters were developed in the form of folding shutters. The shutters are folded sliding and parked perpendicular to the facade. Such Faltschiebeläden can be folded inwards and outwards. Freestanding they serve as visual and / or wind protection. In addition, they can be pushed as a folding package laterally against the wall.
The elements of such Faltschiebeläden consist mostly of extruded aluminum profile and / or -hohlkammerprofil. The surface of the Faltschiebeläden elements is usually powder-coated.

Out EP 2 242 980 A1 For example, a sliding folding shutter is known for closing and releasing at least a part of a building opening. By linear displacement of a first main guide member along a closing axis, a first loading element and second loading element can be closed and opened. The second shop element is pivotally connected in the region of a side edge with the first shop element in the region of its side edge about a vertical axis. The axis is formed by a hinge element. A Faltfassadenanordnung in which two adjacent facade elements are connected to each other via a joint with a single hinge axis is also off DE 20 2007 005 558 U1 known.

Out DE 26 55 235 A1 is known a bellows-type foldable blind. The flat profile elements of the blind are separated by connecting elements. Between the flat profile elements and the connecting elements an articulated connection is formed. For example, eyelets are formed on the side edges of the connecting element and the profile element such that they form a hinge band over the entire length of the side edges.

It is known to operate such Faltschiebeläden manually. Then pressure is exerted on a wing of the Faltschiebeladens through the open window. As a result of this wing shop goes outward and can be pushed aside. For closing the front wing is used, the train continues and also acts on the subsequent wings, whereby the Faltschiebe shutter can be closed again.

This type of opening and closing a folding sliding shutters is on the one hand cumbersome, may already require considerable effort in larger Faltschiebeläden and means in any case for the fingers of the opening or closing person a significant risk of injury, especially in the hinges of Faltschiebeläden.

Based on this prior art, the present invention therefore has for its object to provide Faltschiebeläden which prevent the previously described risk of injury when opening and closing and are easy and effortless to use by people of all ages.

This object is achieved by folding shutters for a window or door element, wherein the respective Faltschiebeladen has more than one protective element and the protective elements are movably interconnected in such a way that a protective element with at least one other protective element is collapsible. The protective elements are substantially adapted to the clear width of the building opening belonging to the window or door element so that two cooperating folding sliding shutters substantially completely cover the building opening designed as a window or door in the unfolded state. The protective elements are mutually over Coupling elements connected, each defining an offset of the protective elements to each other in the unfolded state.

According to one embodiment, the opening and / or closing of the Faltschiebeladens motorized via a cable carried over and / or under the respective Faltschiebeladen and connected to the motor drive, so that the motor drive causes the opening and / or closing of Faltschiebeladens.

Alternatively, the opening and / or closing of Faltschiebeladens motorized via a toothed belt, which is guided over and / or under the respective Faltschiebeladen and connected to the motor drive, so that here causes the motor drive opening and / or closing the Faltschiebeladens.

According to a further embodiment, each protective element has a frame, to the upwardly and / or downwardly facing corner areas attachment plates are mounted, each having a projecting beyond the mounting plate projection, which serves to attach the respective coupling element to the protective element. Each coupling element is held together by two of the protective elements and arranged accordingly between these protective elements.

The projection may have a bolt which engages in a correspondingly complementary bore of the coupling element. In this way, the respective protective element can be rotatably mounted on each of the connections with the coupling element via the bolts.

It can also be provided that the coupling elements arranged between the protective elements are arranged alternately in such a way that they alternately protrude once in the direction of the building opening and the other time.

According to yet another embodiment, each coupling element pointing in the direction of the building opening can be connected to at least one carriage, which cooperates via a running track with a cable pull or a toothed belt which is guided over rollers and connected to the motor drive.

The track can be mounted in each case in the upper and in the lower part of the building opening.

The invention also relates to a method for folding and unfolding folding sliding shutters for a building opening in one of the aforementioned embodiments, in which each protective element is connected to coupling elements which are arranged alternately in the direction of the building opening and facing away from it, so that when moving the Protective elements, the freely movable coupling elements are pressed or stretched outwards and thereby the fully folded or unfolded Faltschiebladen is formed.

According to one embodiment, folding and unfolding may be motor driven. Then, each pointing in the direction of the building opening coupling element is connected to a carriage and this is moved over a arranged in a track rail or timing belt, the protective elements are rotatably mounted at each connection with the coupling elements via bolts and the cable or the timing belt is about a motor is moved to collapse or unfold the protective elements of the Faltschiebeladens, so that when moving the protective elements, the freely movable coupling elements are pressed outwardly or stretched and thereby the fully folded or unfolded Faltschiebeladen is formed.

In the following the invention with reference to an embodiment and its variants and the accompanying drawings will be explained in more detail.

A folding sliding shutter according to the present invention conventionally comprises protective elements 1 consisting of a frame and a filling. In this embodiment, the frame is formed of an extruded aluminum hollow section and has slats, which are also formed of extruded aluminum hollow section. The same applies to the plate carrier. The respective sizes and cross sections of the hollow chamber profiles are correspondingly different and move in the usual and known frame. The slats usually have a horizontal orientation. All surfaces were powder coated at 200 ° C prior to assembly. As a corner joint serve two glued aluminum corner brackets, which are additionally secured by cone bolts. Alternatively, the protective elements may be provided only partially or not at all with lamellae. In place of the lamellae, for example, over the entire surface, a extruded aluminum hollow-chamber profile of defined thickness in horizontal or vertical alignment or a double aluminum plate with an insulating layer can be used, although these details are merely illustrative in nature. For the embodiment of the present invention, this type of design of the protective elements 1 is not important, so that it can be used regardless of model in each type of protective elements of folding sliding shutters. Accordingly, these serve Details for explanation only and are not shown in detail in the figures of the accompanying drawings.

In addition, the invention is not limited to the application in such Faltschiebeladen whose frame and filling are made of aluminum. The invention is much more versatile.

• Aluminium - Holz
• Stahl - Holz
• Aluminium - Stoff
• Stahl - Stoff
• Stahl - Kunststoff
• Aluminium - Kunststoff
• Kunststoff - Kunststoff

In the same way, it is possible to successfully use folding sliding shutters in which frame and filling have the following combinations, always mentioning first the material for the frame and then the material for the filling:

• Aluminum - wood
• Steel - wood
• Aluminum fabric
• Steel - fabric
• Steel - plastic
• Aluminum - plastic
• Plastic - plastic

There are thus basically all conceivable constructions suitable, resulting in a functioning Faltschiebeladen.

In the present embodiment to be explained shows Fig. 1a a number of protective elements 1, which together form the Faltschiebeladen. Usually belonging to a building opening window and / or door element is provided with two such Faltschiebeläden that come together in the extended, ie unfolded state to cover the respective window or the door to which they are attached as fully as possible and protect.

However, the protective elements 1 are not interconnected, as is known and customary in the art, directly adjoining one another, for example, by means of hinges, but instead they have a defined spacing from one another. This distance is defined by coupling elements 3, which are each arranged between the protective elements 1 and connected to the coupling elements 3 are. As Fig. 1a shows, the coupling elements are mounted alternately on the protective elements 1 in such a way that they point once inwards, towards the building, and the other Ma1 outwards. Inside and outside are in Fig. 1a for orientation with A and I indicated. The coupling elements 3 are respectively held on projections 4 of a mounting plate 5, such as Fig. 1b illustrated in more detail.

In Fig. 1b the details are shown with respect to the attachment of the coupling element 3, wherein Fig. 1b the coupling element 3, the plate 5 to which it is attached and shows a rotated by 90 ° view of the mounting plate 5, from which a welded to the mounting plate 5 bolt 7 is closer, in a complementary trained bore 9 at the associated Coupling element 3 engages and the coupling element 3 thereby rotatably supported. Accordingly, the further bore 9 of the coupling element 3 is connected to the adjacent protective element 1.

Fig. 1c shows a sectional view from the outside, from which the positioning of the bolt 7 of the mounting plate 5 in the respective coupling element 3 can be seen.

In Fig. 2 the protective elements 1 of the Faltschiebeladens are shown in the folded state with the corresponding arrangement of the attached to the protective elements 1 coupling elements 3. On the folding and unfolding of the protective elements 1 will be discussed in more detail below.

In the Fig. 3a - 3d For this purpose, different variants are shown in unfolded or unfolded state. These correspond to the Fig. 4a - 4d which show the corresponding folded state.

The variants of Fig. 3a - 3d each have four combined to a Faltschiebeladen protective elements 1, which are interconnected via the coupling elements 3. These are mounted alternately on the protective elements 1, so that they point once inwards, towards the building, and the other time to the outside. To the protection elements 1 from the illustrated, not To bring the folded state in the folded state, each part of the coupling elements 3 is connected to a carriage 11. These are each the coupling elements 3, which point inwards, ie towards the building. The connection to the carriage 11 takes place in the embodiment by screwing. The carriage 11 is in turn connected to a running rail 13, the guide rollers 15 for the cable 17 has. Where the each arranged at the extreme end protection element 1 adjacent to the boundary of a window or door opening, the protective element 1 is held on the projection 4 of the mounting plate 5 to the corresponding carriage 11, which in turn fixed to the running rail 13 is. The mounting plate is in one too Fig. 1b slightly modified, but basically functionally identical form has been used, the Fig. 3e once again in detail shows.

A rubber buffer 19 serves as a stop for the adjacent carriage 11 in the process of folding. First follows on this fixed point, the connection to the adjacent protective element 1 via a in Fig. 3a K1 designated coupling profile. This connection is made so that the coupling element 3 to the outside, ie points away from the window or door opening. A connection to the running rail 13 does not take place. This is again provided on the subsequent connection of this second protective element 1 with the protective element 1 which is in turn adjacent to it. There, the corresponding inward, ie in the direction of the window or door opening facing coupling element 3 is connected to a carriage 11, the two carriages 11 ', cropped and bolted down and up, is formed as Fig. 3a this illustrates. Fig. 6a also shows a detail view of the upper carriage 11, while Fig. 6b a detail view of the lower carriage reproduces. Both in the Fig. 6a and 6b illustrated carriages 11 are composed accordingly from the already mentioned two carriages 11 ', which are each gekupiert and bolted together. In Fig. 3a is denoted by "X" in the area of the connection of the second protection element 3 with the third protection element 3 just described, a detail view which is described in FIG Fig. 7a you can see. The screw connection of the mounting plate at the respective protective element is provided with the reference numeral 20.

The connection of the third with the fourth protective element 1 is again in such a way that the coupling element 3 faces outward, and thus remains freely movable. The outer boundary of the fourth protective element 1 points in the direction of approximately the middle of the window or door opening and is also arranged there in the unfolded state. Here, the protective element 1 via the projection 4 of the mounting plate 5 is connected to a further carriage 11. The further Faltschiebeladen is formed accordingly the same.

At each connection of the protective elements 1 with the coupling element 3, the protective elements 1 are rotatably supported via the bolts 7. When the cable 17 is moved over a motor not shown in the figures, in order to fold the protective elements 1 of the Faltschiebeladens, move the protective elements 1 in the direction of the fixed point. As a result, the freely movable coupling elements 3 are pressed outwards, the two carriages 11 'composite central carriage 11 comes into contact with the rubber buffer 19. At the same time move the guide rollers 15, which are connected to the carriage 11, the, in the direction seen on the center of the window or door opening, outside protection element 1 moves, with a rubber buffer 21 there attached to the central carriage 11, which comprises said two carriages 11 '. At the same time, the interposed, freely movable coupling elements 3 are pressed outwards again. The thus formed, fully folded Faltschiebeladen shows Fig. 4a ,

Basically, the coupling variants of the following differ Fig. 3b - 3d , to which in turn the Fig. 4b - 4d correspond for the finished folded state, only in terms of the formation of the coupling elements 3, which is therefore discussed below.

In the variant according to the Fig. 3a and 4a with the coupling profile K1, the coupling elements 3 each have a nose 23, wherein these are arranged facing each other in the region of the bore 9. These noses 23 are the Folding sliding shutters secured in their folded state. In Fig. 5a is the coupling profile K1 corresponding coupling element 3 again shown separately.

In the coupling profile K2, as the Fig. 3b . 4b show it, the coupling element 3 is in each case arranged between the respective protective elements 1, that its indicated U-shape, in contrast to the coupling profile K1 of the roller 13 opens pioneering. Also this coupling profile K2 is again separately in Fig. 5b shown.

In Fig. 3b is denoted by "X1" in the region of the connection of the second protective element 3 with the third protective element 3 just described, a detail view which is described in FIG Fig. 7b you can see. As a detail that can be found in each of the variants explained here, a stop 25 is to be mentioned, which is optionally attached to the mounting plate 5, here in the embodiment by screwing. Another detail represents a height compensation 27 is provided in the region of the screw connection of the protective element 1 with the mounting plate 5.

With "X2" is in Fig. 3b in the region of the connection of the first protective element 3 with the second protective element 3 is a detail view, the in Fig. 7c you can see. In this detail view after Fig. 7c L denotes the length of the coupling element, which corresponds to the height of the protective element 1, or the Faltschiebeladens total.

In Fig. 3b is still a detailed view in the region of the connection of the second protective element 3 with the third protective element 3 with "Y1" and in Fig. 8 to see. Fig. 8 corresponds with the view from the outside in Fig. 1c , where the embodiment of the mounting plate 5 is slightly different, as already explained.

In the arrangement of the coupling elements 3 according to variant 3, in the Fig. 3c and 4c is shown, the coupling profiles are combined by variant K1 and K2. The respective freely movable coupling element 3 has Noses 23, while the connected to the middle carriage 11 coupling profile 3 is formed according to the coupling profile K2 variant 2.

In the fourth variant of the Fig. 3d and 4d is basically the arrangement of the variant K3 again, with the difference that here the nose 23 has been replaced by an equivalent, more flattened training 25, such as Fig. 5c she shows again in detail.

The example of the motorized via a cable Faltschiebeladens for window or door elements explained invention is also versatile.

Thus, in another embodiment, the cable 17 was replaced by a toothed belt. As a result, the basic structure of the invention Faltschiebeladens and the interaction of its protective elements 1 with the coupling elements 3 is not changed substantially, reference is made with respect to the illustration on the example of the cable 17 described embodiment.

Basically, it is necessary for the folding and pulling apart of the protective elements 1 of Faltschiebeladens no motor drive. An embodiment was also tested which was suitable for manual operation. Here it was found in particular that the risk of injury could be significantly minimized compared to conventional systems.

Basically essential to the invention is thus the interaction of the protective elements 1 with the coupling elements 3, so that in the unfolded state in each case an offset between the individual protective elements 1 is present, and that the coupling elements are movably mounted on the protective elements. As a result, a number of protective elements can be folded together by manually applied pressure or motorized and the folded state can be converted by pulling back into the unfolded state. Without the offset would be possible to pull apart, but not a wrinkle, since the individual protection elements 1 obstructed each other.
