Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a folding sliding door for a building opening as a window or door with more than one protective element, wherein folding and unfolding are carried out by hand or motorbotransfer, and a method for achieving this.

[0002] Traditionally, it is known to use window shutters in the form of folding shutters. Since such folding shutters have to be pivoted sideways, rightwards and leftwards for opening, they need, on the one hand, a not inconsiderable pivot radius and, on the other hand, sufficient space on the respective facade, where they are to be held in the opened state.

[0003] In the case of large-area and wide window fronts, this space is not always sufficiently available and folding doors are no longer usable.

[0004] In order to provide a remedy, windows have been developed in the form of folding sliding doors. In doing so, the window shutters are folded and folded perpendicular to the façade. Such folding slides can be folded inwards and outwards. Freely, they serve as a visibility and / or draft shield.

In addition, they can be pushed sideways against the wall as a folding package.

[0005] It is known to manually operate such folding slides. Then, by the open window, pressure is exerted on a vane of the folding sash. As a result, this slatted door opens outwards and can be pushed aside. For closing, the front wing is drawn up, the train continues and also acts on the following wings, whereby the folding-slide window shutter can be closed again.

This type of opening and closing of a folding-slide window shutter is, on the one hand, cumbersome, can already require a considerable expenditure of force in the case of larger folding slides, and in any case represents a considerable risk of injury to the fingers of the opening or closing person, in particular in the region of the hinges of the Folding sliding shutters.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a folding sliding door which prevents the above-described risk of injury during opening and closing and can thereby be operated by people of any age in a simple and non-cutting manner.

This object is achieved according to the invention by a folding sliding door for a building opening as a window or door, wherein the folding sliding door has more than one protective element, and the protective elements are movably connected in such a way that the one protective element can be folded together with at least one other protective element , The protective elements are essentially adapted to the clear width of the building opening belonging to the window or the door in such a way that two cooperating folding slides substantially completely cover the building opening designed as a window or door in the unfolded state. The protective elements are connected to each other by means of coupling elements which in the unfolded state respectively define an offset or spacing between the protective elements relative to each other.

According to one embodiment, the folding sliding door has a motor drive and its opening and / or closing is thus motor driven via a cable pull or via a toothed belt, which is guided above and / or under the respective folding sliding plate and is connected to the motor drive, Motor drive causes opening and / or closing of the folding sliding door.

[0010] According to a further embodiment, each protective element has a frame, on the upwardly and / or downwardly pointing corner regions, fastening plates are provided, each of which has a projection projecting beyond the fastening plate and serving to secure the respective coupling element to the protective element. Each coupling element is held together by two of the protective elements and is arranged accordingly between these protective elements.

[0011] The projection can 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 the each of the connections with the coupling element via the bolts.

[0012] It may also be provided that the coupling elements arranged between the protective elements are arranged alternately in such a way that they alternate in the direction of the building opening and the other times in alternation.

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

In the mounted state of the window shutter, the running rail is preferably mounted in each case in the upper and lower regions of the building opening.

[0015] The invention also relates to a method of collapsing and unfolding a folding sliding door 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 pointing away therefrom, When the protective elements are moved, the freely movable coupling elements are pressed outwards or stretched outwards, and thereby the folding or unfolded fold-over folds is formed.

[0016] The invention further relates to the motor-driven folding and unfolding of a folding sliding door. Then, each coupling element facing the building opening is connected to a carriage and is moved by a cable pull or toothed belt arranged in a running rail, the protective elements being rotatably mounted on each connection to the coupling elements via bolts, and the cable pull or the toothed belt Is moved by means of a motor in order to fold or unfold the protective elements of the folding sliding leaf so that, when the protective elements are moved, the freely movable coupling elements are pressed out or stretched outwards, thereby forming the folded or unfolded folding sliding doors.

[0019] A folding sliding door according to the present invention comprises protective elements 1, which consist of a frame and a filling. In this exemplary embodiment, the frame is formed from an extrusion-extruded aluminum hollow-chamber profile and has lamellas, which are likewise formed from an extrusion-extruded aluminum hollow-chamber profile. The same applies to the lamellar carriers. The respective sizes and cross-sections of the hollow-chamber profiles are correspondingly different and move in the usual and known frame. As a rule, the lamellae have a horizontal orientation. All surfaces are powdercoated before assembly at 200 ° C. A corner connection is made by two aluminum corner corners, Which are additionally secured by means of tapered pins. Alternatively, the protective elements can also be provided only partially or not at all with lamellas. Instead of the lamellas, for example, an extruded aluminum hollow-chamber profile of defined thickness in horizontal or vertical orientation or a double aluminum plate with an insulating layer can be used over the entire area, although these data are merely exemplary. 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 independently of the model for each type of protective elements of folding slides.

[0020] Furthermore, the invention is not limited to the use with such folding folding doors whose frame and filling are made of aluminum. The invention is far more versatile.

[0021] Folding sliding doors can be successfully used in the same manner, in which the frame and the filling have the following combinations, whereby the material for the frame and subsequently the material for the filling are always mentioned first:

Aluminum - Wood Steel - Wood Aluminum - Fabric Steel - Fabric Steel - Plastic Aluminum - Plastic Plastic - Plastic

In principle, therefore, all conceivable constructions are suitable, which result in a functioning folding sliding door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the exemplary embodiment to be illustrated here, FIG. 1a shows a number of protective elements 1 which together form the folding sliding doors. Usually, a window and / or door element belonging to a building opening is provided with two such folding slides which, in the extended, ie not folded, state, are centrally located in order to cover the respective window or the door to which they are attached as completely as possible And protect.

The protective elements 1 are not, however, adjacent to one another, for example, by means of hinges, as are known and customary in the art, but they have a defined spacing from one another. This distance is defined by coupling elements 3, which are arranged in each case between the protective elements 1 and are connected to the coupling elements 3. As FIG. 1a shows, the coupling elements are alternately attached to the protective elements 1 in such a way that they point once inward, towards the building, and the other time outwards. On the inside and outside, the orientation with A and I is indicated in FIG. 1a. The coupling elements 3 are each held on projections 4 of a fastening plate 5, as illustrated in more detail in FIG. 1 b.

FIG. 1b shows the details relating to the attachment of the coupling element 3, in which FIG. 1b shows the coupling element 3, the plate 5 to which it is attached, and a view of the fastening plate 5 turned through 90 ° from which FIG Of the fastening plate 5, which engages in a bore 9, which is complementary to it, on the associated coupling element 3, and thus keeps the coupling element 3 rotatably supported. Correspondingly, 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 of which the positioning of the bolt 7 of the fastening plate 5 in the respective coupling element 3 can be seen.

In FIG. 2, the protective elements 1 of the folded sliding leaf are shown in the folded-up state with the corresponding arrangement of the coupling elements 3 attached to the protective elements 1. The folding and unfolding of the protective elements 1 will be described in more detail below.

[0026] For this purpose, various variants are shown in FIGS. 3a-3d in a non-folded or unfolded state. 4a-4d, which show the corresponding collapsed state, correspond to this.

The variants of FIGS. 3a-3d each have four protective elements 1, which are combined to form a folding sliding door, which are connected to one another via the coupling elements 3. These are alternately attached to the protective elements 1 so that they point outwards inwards, in the direction of the building, and the other time outwards. In order to bring the protective elements 1 from the illustrated, non-folded state into the folded state, in each case a part of the coupling elements 3 is connected to a carriage 11. These are in each case the coupling elements 3 which point inward, ie toward the building. The connection to the carriage 11 is made by screwing in the exemplary embodiment. The carriage 11 is in turn connected to a running rail 13 which has guide rollers 15 for the cable 17. Where the protective element 1 arranged in each case at the outermost end is located adjacent to the boundary of a window or door opening, the protective element 1 is held by way of the projection 4 of the fastening plate 5 on the corresponding carriage car 11 which in turn is firmly fixed to the running rail 13 is. In this case, the fastening plate has been used in a form which has been slightly modified in accordance with FIG. 1b but has basically the same function, FIG. 3e again shows in detail.

A rubber buffer 19 serves as a stop for the adjacent car 11 in the process of collapsing. First, this connection point is followed by the connection to the adjacent protective element 1 via a coupling profile designated K1 in FIG. 3a. This connection takes place in such a way that the coupling element 3 points outwards, ie, away from the window or door opening. There is no connection to the running rail 13. This is only provided again on the subsequent connection of this second protective element 1 with the protective element 1 adjacent to it. There, the coupling element 3 pointing accordingly inwards, ie, in the direction of the window or door opening, is connected to a carriage 11 which is composed of two trolleys 11 ', coupled and screwed down as well as at the top, as illustrated in FIG. FIG. 6a also shows a detailed view of the upper carriage 11, while FIG. 6b shows a detailed view of the lower carriage. Both carriages 11 illustrated in FIGS. 6 a and 6 b are correspondingly composed of the already mentioned two carriages 11 ', which are respectively coupled and bolted together. In FIG. 3a, a detailed view, which can be seen in FIG. 7a, is designated by "X" in the region of the connection of the second protective element 3 just described with the third protective element 3. The screw connection of the fastening plate to the respective protective element is thereby provided with the reference numeral 20. 6a and 6b are correspondingly composed of the already mentioned two trolleys 11 ', which are respectively coupled and screwed together. In FIG. 3a, a detailed view, which can be seen in FIG. 7a, is designated by "X" in the region of the connection of the second protective element 3 just described with the third protective element 3. The screw connection of the fastening plate to the respective protective element is thereby provided with the reference numeral 20. 6a and 6b are correspondingly composed of the already mentioned two trolleys 11 ', which are respectively coupled and screwed together. In FIG. 3a, a detailed view, which can be seen in FIG. 7a, is designated by "X" in the region of the connection of the second protective element 3 just described with the third protective element 3. The screw connection of the fastening plate to the respective protective element is thereby provided with the reference numeral 20.

The connection of the third protective element 1 to the fourth protective element 1 takes place again in such a way that the coupling element 3 points outwards, and thus remains free to move. The outer boundary of the fourth protective element 1 points towards the center of the window or door opening and is also arranged approximately in the non-folded state. Here, the protective element 1 is connected to another carriage 11 via the projection 4 of the mounting plate 5. The further folding sliding leaf is correspondingly designed in the opposite direction.

On 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 more detail in the FIGURE) in order to fold the protective elements 1 of the folding sliding door, the protective elements 1 move towards the fixed point. As a result, the freely movable coupling elements 3 are pushed outwards. The middle carriages 11 composed of two carriages 11 'thereby come into contact with the rubber buffer 19. At the same time, the guide rollers 15, which are connected to the carriage 11, As seen in the middle of the window or door opening, moves towards the middle carriage 11 with a rubber buffer 21 attached thereon, Which comprises the two trolleys 11. At the same time, the freely movable coupling elements 3 located therebetween are again pressed outwards. FIG. 4a shows the folded folding folds thus formed.

3b-3d, which again correspond to FIGS. 4b-4d for the fully collapsed state, differ only with regard to the design of the coupling elements 3, which will be discussed in the following.

In the variant according to FIGS. 3 a and 4 a with the coupling profile K 1, the coupling elements 3 each have a lug 23, these being arranged facing one another in the region of the bore 9. By means of these lugs 23, the folding sliding doors are secured in their folded-together state. In FIG. 5 a, the coupling element 3 corresponding to the coupling profile K 1 is again shown separately.

3b, 4b, the coupling element 3 is arranged in each case between the respective protective elements 1 in such a way that its indicated U-shape, in contrast to the coupling profile K1, opens away from the track roller 13 , This coupling profile K2 is also shown separately in FIG. 5b.

In FIG. 3b, a detail view, which can be seen in FIG. 7b, is designated by "X1" in the region of the connection of the second protective element 3, which has just been explained, with the third protective element 3. As a detail which is found in each of the variants explained here, a stop 25 is to be mentioned, which is selectively attached to the fastening plate 5, here in the exemplary embodiment by screwing. A further detail is a height compensation 27, which is provided in the region of the screw connection of the protective element 1 with the fastening plate 5. 3b, in the area of the connection of the first protective element 3 to the second protective element 3, a detail view is shown in FIG. 3b, which can be seen in FIG. 7c. In this detailed view according to FIG. 7c, L denotes the length of the coupling element which corresponds to the height of the protective element 1,

Claims

FIG. 3b also shows a detailed view in the area of the connection of the second protective element 3 with the third protective element 3 with "Y1" and can be seen in FIG. FIG. 8 corresponds to the view from the outside in FIG. 1c, where the embodiment of the fastening plate 5 is somewhat different, as already explained. In the arrangement of the coupling elements 3 according to variant 3, which is illustrated in FIGS. 3c and 4c, the coupling profiles according to variant K1 and K2 are combined with one another. The respective freely movable coupling element 3 has noses 23 while the coupling profile 3 connected to the middle carriage 11 is designed according to the coupling profile K2 of the variant 2. In the fourth variant of FIGS. 3d and 4d, the arrangement of the variant K3 is basically found again, With the difference that here the nose 23 has been replaced by an equivalent, more flattened embodiment 25, as FIG. 5c shows it again in detail. The invention, illustrated by way of a cable pulling motor-driven folding sliding door for window or door elements, can also be used in many ways. Thus, in a further exemplary embodiment, the cable pull 17 was replaced by a toothed belt. Since the basic structure of the folded folding drawer according to the invention and the cooperation of its protective elements 1 with the coupling elements 3 essentially do not change as a result, the exemplary embodiment described with reference to the example of the cable pull 17 is referred to with reference to the illustration. [0040] In principle, no motor drive is required for the folding and unfolding of the protective elements 1 of the folding sliding leaf. An embodiment suitable for manual operation was also tested. In particular, it was found that the risk of injury to conventional systems could be significantly reduced. The interaction of the protective elements 1 with the coupling elements 3 is basically essential for the invention, so that an offset or spacing between the individual protective elements 1 is present in the unfolded state, and the coupling elements are mounted movably on the protective elements. As a result, a series of protective elements can be folded together by manually exerted pressure or motor drives, and the collapsed state can be transferred back into the unfolded state by pulling. Without the offset, extraction would be possible, but not folding, since the individual protective elements 1 would interfere with one another. claims
