Description

Description

The present invention relates to a hinge for the movable mounting of at least one cover element on a fixed structure, comprising:

- at least one first fitting part for arrangement on the fixed structure,

- At least one second fitting part for arrangement on at least one cover element.

The invention further relates to a guide system for the movable storage of at least one cover element for covering an opening in a fixed structure, the guide system having at least one hinge, preferably two or more hinges, of the type to be described for the movable storage of the at least one cover element .

The invention further relates to an arrangement with a fixed structure, at least one opening formed therein, at least one cover element and at least one guide system of the type to be described.

[0004] EP 0 763 643 A1 discloses a fitting for the movable mounting of a window or door sash. The fitting is designed to move the sash in a first step from a closed position, in which the sash covers a building opening, to a tilting position, in which the sash is inclined relative to the plane of the building opening. In a second step, the wing can be moved into a position in which the wing is spaced parallel to the building opening and protrudes into the interior of the living space. In a third step, the wing can be moved from the parallel spaced position in a horizontal direction, whereby the building opening can be released. The disadvantage of this is that the sash must be moved from the closed position into a tilting position and then into a parallel position relative to the building opening before the sash can be moved in a horizontal direction. Another disadvantage is that the sash protrudes into the interior in the tilted position, in the parallel position and in a laterally shifted position, which is particularly annoying in confined spaces and makes the arrangement of objects in the area of the window difficult or even impossible might.

The object of the present invention is to provide a hinge of the type mentioned at the beginning, whereby at least one of the disadvantages mentioned above should be avoided.

This is achieved according to the invention by the features of patent claim 1. Further advantageous embodiments of the present invention are defined in the dependent claims.

According to the invention it is provided that the hinge has an articulated lever mechanism through which the two fitting parts can be moved essentially linearly between a first end position, which corresponds to a closed position of the cover element, and a second end position, which corresponds to an open position of the cover element , and wherein at least one carriage with at least one roller is arranged on at least one of the two fitting parts for displaceable mounting of the hinge along at least one guide.

In other words, the hinge has an articulated lever mechanism for the articulated connection between the two fitting parts, the two fitting parts of the hinge being linearly movable relative to one another. In this way, movement of the cover element in parallel planes is possible, i.e. the cover element can be moved parallel to itself.

In this way, a simple and intuitive opening movement of the cover element with precise straight guidance is possible without the cover element having to be moved or tilted transversely to the plane of a fixed frame during the opening movement.

After moving the cover element between the first, closed end position and the second, open end position, at least one fitting part of the hinge can be moved via at least one carriage with at least one roller along a guide into a lateral displacement position in which the opening of the fixed structure can be essentially released by the cover element.

Fig. 1a shows a fixed structure 1 with an opening 3 (Fig. 1c), the opening

3 can be covered by at least one cover element 2. The cover element 2 can be made in one piece or in several parts. In a multi-part design of the cover element 2, the individual parts of the cover element 2 can be connected to one another in a movable, for example pivotable, manner.

The cover element 2 can be a window, a panel and/or a door. In a closed state, the cover element 2 can be arranged flush with the fixed structure 1 or slightly protruding in the opening 3 of the fixed structure 1.

The fixed structure 1 can be, for example, an inner or outer building wall.

The opening 3 of the stationary structure 1 can be, for example, a window opening or a door opening.

In a closed position, the cover element 2 essentially completely covers the opening 3, with a plane of the cover element 2 formed by an outside and an outside of the stationary structure 1 being arranged essentially coplanar (i.e. essentially flush with the facade) with one another. However, it can also be provided that the cover element 2 protrudes slightly beyond the outside of the stationary structure 1.

Starting from the closed position according to FIG. 1a, the cover element 2 can be moved outwards in a linear direction into an open position, in which the cover element 2 is spaced essentially parallel from the opening 3.

In a first movement section, the cover element 2 can be moved in parallel relative to the stationary structure 1, for example in order to be able to ventilate a room in a building. This can be done either manually or by at least one, preferably automated and/or electric motor, drive device 25 (FIG. 9a).

[0036] According to an exemplary embodiment, it can be provided that the at least one drive device 25 is coupled or can be coupled to a control or regulating device, preferably a building control system. Here, at least one sensor, preferably a CO2 sensor system, can be provided for measuring a property of a building, wherein the at least one drive device 25 can be activated by the control or regulating device, particularly preferably depending on a sensor signal from the at least one sensor.

[0037] For example, depending on lighting conditions, a time of day, a temperature, a humidity and/or an air quality, the building control can initiate the at least one drive device 25 in order to move the cover element 2 into a partial or completely open position for ventilation of the room .

In a second movement section of the cover element 2, movement outside of space along the stationary structure 1 and orthogonally to the direction of the previous first movement section is possible.

1b shows the cover element 2 in a position spaced orthogonally from the opening 3.

In the exemplary embodiment shown, four hinges 4a, 4b, 4c, 4d are provided, through which the cover element 2 moves essentially linearly between a first end position, which corresponds to a closed position of the cover element 2, and a second end position, which corresponds to an open position of the cover element 2 corresponds, is movable.

The two hinges 4a, 4d arranged one above the other are attached to the stationary structure 1, with a carriage 19 (FIGS. 7a-7c) of the hinges 4a, 4d running along at least one guide 8a, 8b (FIGS. 4a) attached to the cover element 2 ) is movable.

The other two hinges 4b, 4c arranged one above the other are, however, fastened to the cover element 2, with a carriage 19 (FIGS. 7a-7c) of the hinges 4b, 4c running along at least one guide 5a, 5b to be fastened to the stationary structure 1 ( Fig. 4a) is movable.

In the exemplary embodiment shown, two guides 8a, 8b (FIG. 4a) spaced apart from one another in a height direction are fastened to the cover element 2 and two guides 5a, 5b (FIG. 4a) spaced apart from one another in a height direction are fastened to the stationary structure 1.

[0044] According to one exemplary embodiment, it can be provided that the, preferably substantially square, cover element 2 is placed essentially vertically, for example approximately 125 mm, outwards at the four corners, starting from the closed position according to FIG. 1a (FIG. 1b). .

The guide system 11 can have four hinges 4a-4d, which are arranged in the area of the four corners of the cover element 2 in the closed position. Preferably, it can be provided that two hinges 4a, 4d are arranged vertically spaced apart from one another on the stationary structure 1 and two hinges 4b, 4c are arranged vertically spaced apart from one another on the cover element 2 and are connected in a movement-coupled manner to the cover element 2.

This can be done by a common, preferably electric, drive device 25 (FIG. 9a).

1b, the cover element 2 can be moved into a displacement position in which the cover element 2 is arranged laterally offset relative to the opening 3.

1c shows the cover element 2 in a displacement position in which the cover element 2 is arranged laterally offset relative to the opening 3. The hinges 4a, 4d are attached to the stationary structure 1, whereas the carriages 19 of the other two hinges 4b, 4c can be moved along the guides 5a, 5b.

2a shows the stationary structure 1 in a perspective view. The stationary structure 1 has at least one fold 6 surrounding the opening 3, two opposing reveals 1a, a window sill 1b and a lintel 1c.

2b shows the cover element 2 in a perspective view. The cover element 2 is mounted to be linearly movable relative to a frame 7 to be fastened to the stationary structure 1 via the hinges 4a, 4b, 4c, 4d, so that the cover element 2 is always parallel between the first end position (closed position) and the second end position (open position). can be guided to the frame 7.

A hinge 4a, 4b, 4c, 4d with two pairs of toggle levers is arranged at each of the four corners, with two hinges 4a, 4d being arranged on the building side on the stationary structure 1 and two hinges 4b, 4c on the cover element 2.

The movement of the hinges 4a, 4b, 4c, 4d is, on the one hand, horizontally synchronized and, on the other hand, vertically synchronized. In the case of the hinges 4a, 4b, 4c, 4d, a pair of toggle levers has a supporting function and a pair of toggle levers has a movement-guiding function.

[0053] By means of at least one toggle lever of the hinges 4a, 4b, 4c, 4d, starting from the first end position (closed position), a high power transmission with a low travel ratio can be brought about in a first movement path, then a high travel transmission with reduced power transmission takes place in a second movement path until the second end position (open position) is reached.

A very compact design of the hinges 4a, 4b, 4c, 4d is possible by using at least one toggle lever.

A further advantage of using at least one toggle lever is that a rotary movement of a, preferably electric, drive device 25 (FIG. 9a) can be very easily translated into a linear movement of the cover element 2.

In a mounted state of the cover element 2, the frame 7 is arranged essentially flush with the reveal 1a and/or flush with the window sill 1b and/or flush with the lintel 1c, so that between the frame 7 and the reveal 1a, the window sill 1b and /or that

Lintel 1c no disruptive abutting edge is formed.

Due to the flush surfaces between the frame 7, the reveal 1a, the window sill 1b and the lintel 1c, a person in the interior gets the impression that a glass surface formed by the cover element 2 without the formation of a step up to the Reveals 1a, window sill 1b and lintel 1c are enough.

The guides 5a, 5b are each integrated in the frame 7 and the other guides 8a, 8b are each integrated in the cover element 2. When the cover element 2 is closed, the guides 5a, 5b of the frame 7 and the guides 8a, 8b arranged on the cover element 2 are not visible.

3a shows the cover element 2 in a closed position relative to the stationary structure 1 in a cross-sectional view.

It can be seen that the frame 7 of the cover element 2 as well as the reveals 1a, the window sill 1b and the lintel 1c of the stationary structure 1 run flush with one another. In this way, a surface formed by the opening 3 of the stationary structure 1 can be essentially completely covered by a surface of the cover element 2, preferably made of glass.

3b shows the cover element 2 in an open position, in which the cover element 2 is spaced essentially orthogonally from the opening 3. The cover element 2 can be moved linearly between the closed position and the open position shown by the hinges 4a, 4b, 4c, 4d.

3c shows the area “A” circled in FIG. 3a in an enlarged view. The guide 8b can be seen, which is essentially completely integrated in the cover element 2. The frame 7 of the cover element 2 and the window sill 1b are essentially coplanar relative to one another.

[0063] On the one hand, the hinge 4d is attached to the stationary structure 1, with the guide 8b attached to the cover element 2 being movable along the carriage 9 with at least one roller 9a when the cover element 2 moves between the open position and the displacement position.

[0064] A synchronization device 10 can be seen, through which a movement of at least two hinges 4a-4d can be synchronized with one another.

In the exemplary embodiment shown, the synchronization device 10 has at least one synchronization shaft 10a and/or at least one cable pull 9 (FIG. 9a), through which a movement of at least two hinges 4a-4d can be synchronized with one another.

4a shows a guide system 11 with several, preferably exactly four, hinges 4a, 4b, 4c, 4d for the movable mounting of the cover element 2.

[0067] The guide system 11 includes an upper guide 5a, which is to be attached to or in the stationary structure 1. Another guide 8a is to be attached to or in the cover element 2. Through the hinges 4a, 4b, a distance between the two guides 5a, 8a (and thus a position of the cover element 2) can be changed in a linear direction.

[0068] The guide system 11 further comprises a lower guide 5b, which is to be attached to or in the stationary structure 1. Another guide 8b is to be attached to or in the cover element 2. Through the lower hinges 4c, 4d, a distance between the two guides 5b, 8b (and thus a position of the cover element 2) can be changed in a linear direction.

[0069] The recessed guides 5a, 5b, 8a, 8b enable the cover element 2 to be designed to be flush with the surface and no guide 5a, 5b, 8a, 8b to be visible in the closed state.

The guides 5a, 5b, 8a, 8b are preferably designed as guide rails. 4b shows the area framed in FIG. 4a in an enlarged view. At this

Position the hinge 4c can be seen, whereby the structure of the hinges 4a, 4b, 4c, 4d can basically be identical.

The hinge 4c has a first fitting part 17a for arrangement on the cover element 2, preferably for arrangement on the guide 8b of the cover element 2.

A second fitting part 17b is designed for displaceable storage on the stationary structure 1, preferably for displaceable storage along the guide 5b to be fastened to the stationary structure 1.

[0074] The two fitting parts 17a, 17b are connected to one another via an articulated lever mechanism 12 in such a way that the two fitting parts 17a, 17b move essentially linearly between a first end position, which corresponds to a closed position of the cover element 2, and a second end position, which corresponds to an open position of the Cover element 2 corresponds, are movable.

The two fitting parts 17a, 17b are further apart from one another in the second end position than in the first end position. For example, it can be provided that the two fitting parts 17a, 17b in the second end position have a distance between 50 mm and 200 mm, particularly preferably a distance between 100 mm and 150 mm, from one another.

In the exemplary embodiment shown, the articulated lever mechanism 12 has at least two support levers 13a, 13b that are articulated to one another via a first hinge axis 14 and at least two drive levers 15a, 15b that are articulated to one another via a second hinge axis 16.

[0077] According to a preferred embodiment, the two joint axes 14, 16 run essentially orthogonally to one another.

5a shows the guide system 11 according to FIGS. 4a, 4b in further relative positions of the hinges 4a, 4b, 4c, 4d to one another. The two hinges 4a, 4d arranged one above the other are designed to be stationary relative to the stationary structure 1, with the guide 8a to be attached to the cover element 2 being movable relative to a carriage 19 of the fixed hinges 4a, 4d.

[0079] The other two hinges 4b, 4c, on the other hand, are to be fastened to the cover element 2 and are when the cover element 2 moves between the open position, in which the cover element 2 is spaced essentially orthogonally from the opening 3, and the displacement position, in which the cover element 2 is arranged laterally offset relative to the opening 3, movably mounted along the guides 5a, 5b to be fastened to the stationary structure 1.

5b shows the area framed in FIG. 5a in an enlarged view. The articulated lever mechanism 12 has two support levers 13a, 13b which are connected to one another via a first articulated axis 14 and which accommodate a load of the cover element 2.

The two drive levers 15a, 15b of the articulated lever mechanism 12 are connected to one another via a second articulated axis 16, the relative distance between the two fitting parts 17a, 17b from one another being changeable by the drive levers 15a, 15b.

The two joint axes 14, 16 can run essentially orthogonally to one another.

The drive lever 15b is connected to the synchronization shaft 10a of the synchronization device 10 via a positive connection 18. In this way, a rotational movement of a drive lever 15a, 15b of a first hinge 4a-4d can be synchronized with a rotational movement of a drive lever 15a, 15b of a second hinge 4a-4d.

[0084] Preferably, it can be provided that at least one hinge 4a-4d is mounted displaceably at least in sections along the at least one synchronization shaft 10a of the at least one synchronization device 10. This way is a compact

Design possible with precise linear guidance of the hinge 4a-4d along the synchronization shaft 10a.

In the exemplary embodiment shown, at least one hinge 4a-4d is mounted displaceably along the synchronization shaft 10a of the synchronization device 10 via at least one positive connection 18.

The hinges 4b, 4c are therefore movably mounted along the guides 5a, 5b to be fastened to the stationary structure 1 and/or along at least one synchronization shaft 10a of the synchronization device 10.

[0087] When the hinge 4a-4d moves from the first end position to the second end position, a distance of the at least one second fitting part 17b relative to the at least one first fitting part 17a can be increased, so that an inside of at least one can be connected to the at least one second fitting part 17b Covering element 2 in the second end position is further spaced from at least one first fitting part 17a than in the first end position. In other words, the cover element 2 can be opened to the outside relative to the fixed structure 1.

6a shows the guide system 11 in the displacement position of the cover element 2, in which the cover element 2 is arranged laterally offset relative to the opening 3 of the stationary structure 1. The position of the cover element 2 therefore corresponds to the position of the cover element 2 according to FIG. 1c.

[0089] It can be seen that the two hinges 4b, 4c arranged on the cover element 2, when the cover element 2 moves between the open position, in which the cover element 2 is spaced essentially orthogonally from the opening 3, and the displacement position, in which the cover element 2 is arranged laterally offset relative to the opening 3, along the two guides 5a, 5b which are spaced apart in the height direction and/or along the two synchronization shafts 10a of the synchronization device 10 which are spaced apart in the height direction.

6b shows the area framed in FIG. 6a in an enlarged view.

The hinges 4b, 4c are each arranged on the guides 8a, 8b to be fastened to the cover element 2, the second fitting parts 17b of the hinges 4b, 4c each being movable along the guides 5a, 5b to be fastened to the stationary structure 1.

[0092] The other two hinges 4a, 4d, on the other hand, are arranged on the guides 5a, 5b to be fastened to the stationary structure 1, with the two second fitting parts 17b of the hinges 4a, 4d each relative to the guides 8a, which are to be fastened to the cover element 2. 8b are movable.

7a-7c show the hinge 4d in different relative positions of the fitting parts 17a, 17b to one another.

7a shows the closed position of the hinge 4d, with the two fitting parts 17a, 17b being at the smallest distance from one another.

7b shows an intermediate position of the hinge 4d, which corresponds approximately to the half-open position of the cover element 2 between the first end position (closed position) and the second end position (open position).

7c shows the second end position (open position) of the hinge 4a-4d. In the second end position, a buckling movement of one of the toggle lever pairs is blocked in at least one hinge 4d in order to prevent the hinge 4d from buckling when the cover element 2 is moved laterally.

In order to be able to move the cover element 2 from the second end position into the lateral displacement position, at least one unlocking element (not shown), for example a clamping lever, must be actuated, which serves in particular for child safety. In other words, it should be avoided that a child moves the cover element 2 laterally and

falls out of the opening 3 of the stationary structure 1.

The at least one unlocking element can also be coupled to a brake, with the cover element 2 on the guides 5a, 8a; 5b, 8b is automatically locked in any position when the unlocking element is released.

In other words, the unlocking element must be actuated in order to be able to move the cover element 2 laterally. This function is also intended to prevent the cover element 2 from being displaced laterally by strong wind.

A handle of the unlocking element can be arranged to be retractable in the window frame, whereby the handle is not visible in the closed position flush with the facade.

By folding out the handle, the unlocking and/or the brake can be released automatically to enable movement of the cover element 2 between the second end position and the lateral displacement position. The handle can either be adjustable in different positions or, in the case of the brake, can be infinitely adjustable.

8 shows the hinge 4d in an exploded view.

[00103] According to possible exemplary embodiments, it can be provided that the joint lever

Belmechanism 12

- has more than four, preferably exactly six, joint axes 14, 16, 20, 21, 22, 23, and / or

- has at least one, preferably more than one, support lever 13a, 13b and / or at least one, preferably more than one, drive lever 15a, 15b, which is partially curved or angled.

At least one fitting part 17a, 17b can have at least one, preferably circular, recess 24, which is provided for the passage of a synchronization shaft 10a and/or for the displaceable mounting of a fitting part 17a, 17b along the synchronization shaft 10a of the synchronization device 10.

A tilting moment of the cover element 2 during a movement between the second end position (open position) and the lateral displacement position can be compensated for by at least one deflection roller 27 and at least one cable pull 28 (FIG. 9b). This function is explained in more detail in connection with FIGS. 9a, 9b.

9a shows part of the guide system 11 in a perspective view. You can see the upper hinge 4a and the lower hinge 4d. The hinges 4a, 4d are arranged in a fixed position relative to the stationary structure 1 in a mounting position.

A movement of the lower hinge 4d with the other (not shown here) lower hinge 4c can be synchronized via the lower synchronization shaft 10a.

A movement of the two upper hinges 4a, 4b can be synchronized with one another by means of an upper, second synchronization shaft 10a.

[00109] The fitting parts 17a of the hinges 4a, 4d are positively connected to the synchronization shafts 10a of the synchronization device 10 associated with them, so that when the synchronization shaft 10a rotates, the fitting parts 17a of the hinges 4a, 4d can also be moved.

It is preferably provided that at least one hinge 4a-4d can be driven by a, preferably electric, drive device 25 between the first end position (closed position) and the second end position (open position).

The, preferably electric, drive device 25 can be controlled, for example, via at least one radio switch.

As an alternative or as a supplement to an electric motor drive device 25, at least one manual drive device 25 can be provided, for example a hand crank. For example, a hand crank can be used in the event of a power failure on an electric motor.

cal drive device 25 may be useful.

In the exemplary embodiment shown, the lower synchronization shaft 10a of the synchronization device 10 can be driven by at least one, preferably electric, drive device 25.

The synchronization device 10 further comprises at least one cable pull 9, by means of which a vertical synchronization, i.e. a movement of at least two hinges 4a, 4d arranged one above the other, can be synchronized with one another.

In the exemplary embodiment shown, the cable pull 9 comprises at least two drive rollers 26a, 26b and at least one cable 10b, which is arranged between the drive rollers 26a, 26b and preferably runs in the shape of a figure eight.

The vertical synchronization of the hinges 4a, 4d therefore includes a cable eight, which enables the two horizontal synchronization shafts 10a to rotate in opposite directions.

The lower drive roller 26b can be driven by the, preferably electric, drive device 25, with a rotational movement of the lower drive roller 26b being transferable to the upper hinge 4a via the cable 10b of the synchronization device 10 and via the at least one further drive roller 26a.

Preferably, it can be provided that a rotational movement of the upper drive roller 26a can be transferred to the upper hinge 4a and/or to the other upper hinge 4b (not shown here) via an upper synchronization shaft 10a.

The arrangement of the drive device 25 is possible at various points. For example, the drive device 25 can be arranged at one of the corners or in the middle on a vertical side of the frame 7 (Fig. 2b).

It can also be provided that at least two, preferably electric, drive devices 25 are provided, which are arranged diagonally at the corners of the frame 7. In such a case, the arrangement of an upper synchronization shaft 10a can be dispensed with.

The two horizontal synchronization shafts 10a are rotated by approximately 120° between the closed position and the open position during the opening movement of the cover element 2.

The closing movement of the cover element 2, starting from the lateral displacement position via the second end position (open position) into the first end position (closed position), takes place in reverse.

In order to detect the reaching of the second end position (open position) of at least one hinge 4a-4d, at least one sensor (e.g. a metal detector) or a switch can be provided, which activates the power supply to the drive device 25 or during the opening movement of the cover element 2 between the first end position (closed position) and the second end position (open position). This ensures that the drive device 25 can only be activated when the second end position is reached. The switch can be actuated, for example, by a moving carriage 19 of one of the window-side hinges 4b, 4c.

The cover element 2 can be releasably locked in the first end position (closed position) in order to achieve a defined closed position and to prevent a break-in. This can be achieved via at least one locking device 37 (FIG. 13), for example with at least one lockable bolt 40a, 40b.

9b shows the lower region of the guide system 11 according to FIG. 9a in another perspective view.

The lower drive roller 26b, which can be driven by the drive device 25, can be seen, with the cable 10b of the synchronization device 10, preferably several times, around the

Drive roller 26b is guided.

When moving the cover element 2 from the open position into the lateral displacement position, the cover element 2 increasingly tends to tilt downward to the left in the plane of the cover element 2 due to gravity (FIG. 10).

In order to compensate for this tilting moment, at least one cable pull 28 is provided, a length of the cable pull 28 being shortened by a shortening device when the cover element 2 is moved from the second end position (open position) of the fitting parts 17a, 17b into the lateral displacement position of the cover element 2 becomes.

The shortening device can, for example, have a conical drum, with the cable pull 28 being able to be wound up and/or unwound in a non-linear manner as the opening movement of the cover element 2 progresses.

Alternatively or in addition to a conical drum, a position of at least one deflection roller 27 can be changed to shorten the length of the cable pull 28.

In other words, the cable pull 28, which is required for the load transfer of the lateral displacement movement, is designed in such a way that the moment increases as the opening movement progresses, preferably through the conical drum and/or by changing the position of at least one deflection roller 27, is balanced. This prevents the cover element 2 from being lowered. It would also be possible for the cover element 2 to even be slightly raised by the cable 28 when the cover element 2 moves between the open position and the displacement position.

10a shows the cover element 2 in the second end position (open position) relative to the stationary structure 1, with the guide 5b being attached to or in the stationary structure 1 and with the hinges 4a, 4d being arranged in a fixed manner relative to the guide 5b .

The synchronization shaft 10a of the synchronization device 10 can be seen. The synchronization shaft 10a can have a plurality of grooves 29 running in the longitudinal direction of the synchronization shaft 10a, which serve for positive fastening and/or for displaceable mounting of at least one hinge 4a-4d.

In the exemplary embodiment shown, the synchronization shaft 10a is rotatably mounted about an axis of rotation, the axis of rotation of the synchronization shaft 10a running coaxially to a joint axis 22 of the hinge 4d.

The other fitting part 17b can be moved via a carriage 19 with at least one roller 19a along a guide 8b fastened to or in the cover element 2.

By means of a centering device 30, at least one drive lever 15a, 15b can be centered relative to the cover element 2 and prevents excessive relative movement between the cover element 2 and the drive levers 15a, 15b when the cover element 2 is in the closed position (FIG. 10b).

The centering device 30 comprises at least one mounting part 30a to be fastened to the cover element 2 with an opening 30b, with at least one projection 30ce arranged on the drive lever 15b engaging in the opening 30b of the mounting part 30a in the closed position of the cover element 2.

10b shows the guide system 11 in a position which corresponds to the closed position of the cover element 2 relative to the stationary structure 1. For reasons of clarity, the cover element 2 is not shown. It can be seen that the at least one projection 30c of the drive lever 15b engages in the opening 30b of the mounting part 30a of the centering device 30.

11a-11d show the cover element 2 in different versions. Of course, other designs or material combinations are also possible to reduce thermal conductivity and/or thermal bridges.

11a shows a first embodiment, wherein the cover element 2 is designed as vacuum insulating glass and is movable relative to the stationary structure 1 via a cover frame 31. The cover frame 31 here has a profile 35, preferably made of wood, and at least one further profile 32a. The profile 32a can be made of metal, preferably aluminum, or plastic.

The cover frame 31 can be sealed in the closed position of the cover element 2 relative to the stationary structure 1, in particular to the frame 7 (FIG. 2b) of the cover element 2, by means of at least one, preferably strip-shaped, sealing element 33.

11b shows a second embodiment, wherein the cover element 2 is designed as vacuum insulating glass and is movable relative to the stationary structure 1 via a cover frame 31. The cover frame 31 here has at least two interconnected profiles 32a, 32b, for example made of metal, in particular aluminum. The cover frame 31 can be sealed relative to the stationary structure 1 in the closed position of the cover element 2 by means of at least one, preferably strip-shaped, sealing element 33.

11c shows a third embodiment, wherein the cover element 2 is formed as a shiplap glass with two or more glass plates 34a, 34b, 34c, preferably with different thicknesses, the glass plates 34a, 34b, 34c being spaced apart from one another at least in certain areas. Between the glass plates 34a, 34b, 34c there are cavities which are sealed gas-tight and moisture-tight and which serve for sound and heat insulation.

The cover frame 31 has at least a first profile 35, preferably made of wood, and at least one second profile 32a connected to the profile 35. The second profile 32a can be made of metal or plastic, for example. The cover frame 31 can be sealed relative to the stationary structure 1 in the closed position of the cover element 2 by means of at least one, preferably strip-shaped, sealing element 33.

11d shows a fourth embodiment, wherein the cover element 2 is designed as vacuum insulating glass and the cover frame 31 has at least two profiles 32a, 32b made of different materials. In the exemplary embodiment shown, the profile 32a is made of plastic and/or the other profile 32b is made of metal, in particular aluminum. The cover frame 31 can be sealed relative to the stationary structure 1 in the closed position of the cover element 2 by means of at least one, preferably strip-shaped, sealing element 33.

12a and 12b show two different embodiments of a cover element 2 with a multi-pane insulating glass, which - as already shown in Fig. 11c - has two or more glass plates 34a, 34b, 34c spaced apart from one another at least in some areas. The profile 32a is made, for example, of metal or plastic and is designed to accommodate at least some areas of the other profile 35, preferably on wood or a wood material.

13 shows an exploded view of a part of the guide system 11 with at least one locking device 37 for releasably locking the two fitting parts 17a, 17b in the first end position and/or in the second end position.

Preferably, it can be provided that at least one support lever 13a, 13b and/or at least one drive lever 15a, 15b of the joint mechanism 12 can be releasably locked by the at least one locking device 37.

The first fitting part 17a has a base body 36 with at least one contact surface 36a, which is designed to contact the fixed structure 1. In the exemplary embodiment shown, the base body 36 of the first fitting part 17a is to be attached to the fixed structure 1 via a mounting part 52.

The locking device 37 is useful in order to lock the fitting parts 17a, 17b in the first end position (closed position) and in the second end position, so that no relative movement of the articulated lever mechanism 12 takes place during the lateral displacement movement of the cover element 2.

In the exemplary embodiment shown, the articulated lever mechanism 12 has at least two drive levers 15a, 15b connected to one another via an articulated axis 16, wherein at least one of the drive levers 15a, 15b, preferably both drive levers 15a, 15b, can be releasably locked by the locking device 37.

The locking device 37 has at least one bolt 40a, 40b and at least one locking contour 42a, 42b, preferably open on one side, the at least one bolt 40a, 40b being received in the first end position within the locking contour 42a, 42b.

Preferably, it can be provided that the at least one bolt 40a, 40b can be inserted into the locking contour 42a, 42b when the hinge 4a-4d moves from the second end position into the first end position.

In the exemplary embodiment shown, the at least one bolt 40a, 40b is arranged on a locking lever 38, preferably wherein the locking lever 38 is mounted on the first fitting part 17a so that it can pivot about an axis 39.

[00155] It can preferably be provided that at least two bolts 40a, 40b are provided on the locking lever 38, which engage in corresponding locking contours 42a, 42b of the drive levers 15a, 15b in the first end position (closed position) of the two fitting parts 17a, 17b.

To control a movement of the locking lever 38, at least one drive roller 26b is provided, which can be set into a rotary movement by the, preferably electric, drive device 25.

The drive roller 26b has at least one, preferably curved, control cam 43, with a pin 41 of the locking lever 38 being guided in the control cam 43.

By means of a, preferably motor-assisted, rotary movement of the drive roller 26b, the pin 41 of the locking lever 38 can be guided along the control cam 43 of the drive roller 26b, the two bolts 40a, 40b of the locking lever 38 being used to lock the two fitting parts 17a, 17b in the first End position can be moved into the locking contours 42a, 42b of the drive levers 15a, 15b and can be moved out of the locking contours 42a, 42b for unlocking.

To lock the second end position (open position) of the fitting parts 17a, 17b, the joint axis 16, which connects the two drive levers 15a, 15b to one another, can be moved into an over-center position. In this way, the two drive levers 15a, 15b are fixed in their relative position to one another in the second end position (i.e. in an extended position of the two drive levers 15a, 15b to one another) with a predetermined holding force.

In addition, the locking device 37 can have at least one pin 44b and at least one stop 48 for locking the two fitting parts 17a, 17b in the second end position, the at least one pin 44b in the second end position of the fitting parts 17a, 17b on at least one stop 48 is present.

Preferably, it can be provided that at least one guide contour 47 is provided for the displaceable mounting of the at least one pin 44b and the at least one stop 48 is formed at one end of the guide contour 47.

Preferably, it can be provided that the at least one guide contour 47 is formed on the first fitting part 17a, preferably on the base body 36 of the first fitting part 17a.

The control cam 43 of the drive roller 26b and the guide contour 47 of the first fitting part 17a can be designed to be essentially mirror-symmetrical to one another.

The at least one pin 44b for locking the second end position of the two fitting parts 17a, 17b relative to one another can be arranged on a slide 44.

[00165] Preferably, it can be provided that the at least one slider 44 is movably mounted on the drive roller 26b. In the exemplary embodiment shown, the slide 44 has at least one pin 44a, which is movably arranged in an elongated hole 46 in the drive roller 26b.

The drive roller 26b can have a, preferably linear, guide 45 for movably mounting the slide 44. Through the guide 45, the slide 44 can be moved at least in sections radially in the direction of the axis of rotation of the drive roller 26b.

The fitting parts 17a, 17b of the hinge 4a-4d can be moved into the first end position and/or into the second end position by the, preferably electric, drive device 25.

[00168] In addition, the two fitting parts 17a, 17b can be releasably locked and/or releasably unlocked in the first end position and/or in the second end position by a movement, in particular a rotary movement, of the drive device 25.

The first pin 44a of the slide 44 is received in an elongated hole 46 of the drive roller 26b, the slide 44 being movable along the guide 45 of the drive roller 26b.

The second pin 44b of the slide 44 is guided along a control cam 50 of a control part 49 and along the guide contour 47 of the first fitting part 17a.

The control part 49 with the control cam 50 is firmly connected to the drive lever 15a, with no relative movement taking place between the drive lever 15a and the control part 49. The drive lever 15a and the control part 49 with the control cam 50 therefore form a common structural unit.

The two pins 44a, 44b of the slide 44 run coaxially to one another and/or can be formed in one piece together with the slide 44.

14a-14d show the unlocking of the first end position of the two fitting parts 17a, 17b of the hinge 4a-4d in time sequences.

14a shows the first end position of the fitting parts 17a, 17b relative to one another, which corresponds to a closed position of the cover element 2 relative to the stationary structure 1. It can be seen that the two bolts 40a, 40b of the locking lever 38 engage in the locking contours 42a, 42b of the drive levers 15a, 15b. Thus, the two drive levers 15a, 15b are releasably locked by the locking device 37 in the first end position of the fitting parts 17a, 17b.

14b shows that the drive roller 26b was rotated clockwise by the, preferably electric, drive device 25. The bolt 40b of the locking lever 38 is guided in the control contour 43 of the drive roller 26b, the locking lever 38 pivoting about the axis 39 of the first fitting part 17a and the two bolts 40a, 40b of the locking lever 38 from the two locking contours 42a, 42b of the drive lever 15a, 15b can be moved out.

14c shows a continued clockwise rotation of the drive roller 26b, with the bolt 40b of the locking lever 38 being guided along the, preferably arcuate, control contour 43 and the locking lever 38 being pivoted further about the axis 39 of the first fitting part 17a.

14d shows that the two bolts 40a, 40b of the locking lever 38 have now been completely moved out of the locking contours 42a, 42b of the drive levers 15a, 15b by a continued rotational movement of the drive roller 26b.

It should be noted that the two drive levers 15a, 15b have not yet moved about the joint axis 16 between the positions according to FIGS. 14a and 14d. The drive levers 15a, 15b therefore remain in their relative position to one another between the first end position of the fitting parts 17a, 17b up to a rotation angle of the drive roller 26b of approximately 30°.

The position according to FIG. 14d, however, signals the beginning of a pivoting movement of the two drive levers 15a, 15b relative to one another. The slide 44 can be guided along the guide 45 of the drive roller 26b in a radial direction to the axis of rotation of the drive roller 26b.

The first pin 44a of the slide 44 is movably mounted in the elongated hole 46 of the drive roller 26b. The second pin 44b of the slide 44 engages in the curved control cam 50 of the control part 49 and in the guide contour 47 (FIG. 13) of the first fitting part 17a.

The control cam 50 of the control part 49 can have at least two sections which are arranged at an angle to one another, for example at an angle of approximately 90°.

By rotating the drive roller 260 and through the interaction of the second pin 44b with the control cam 50 and with the guide contour 47, the first pin 44a of the slide 44 is moved to the other end of the elongated hole 46. In this way, a torque-transmitting connection is established between the drive roller 26b and the slider 44.

So if the drive roller 26b is driven clockwise by the, preferably electric, drive device 25, the first drive lever 15a is via the slide 44 and via the control part 49, which is firmly connected to the first drive lever 15a, from the position according to FIG. 14d can be moved with the drive roller 26b.

15a-15c show the drive of the fitting parts 17a, 17b in the direction of the second end position in time sequences.

The two locking contours 42a, 42b of the two drive levers 15a, 15b for locking the first end position (closed position) of the two fitting parts 17a, 17b to one another can be clearly seen here.

Starting from the start of the drive movement according to the previous FIG. 14d, the first drive lever 15a can be driven via the slide 44. A, preferably motor-assisted, rotary movement of the drive roller 26b is transmitted to the control part 49 via the two pins 44a, 44b of the slide 44, the control part 49 being connected in a rotationally fixed manner to the first drive lever 15a.

15b shows a continued drive movement of the two fitting parts 17a, 17b in the direction of the second end position. A rotational movement of the drive roller 26b can be transmitted to the first drive lever 15a via the slide 44. The two support levers 13a, 13b can be seen here, which are connected to one another in an assembly position via the vertically extending joint axis 14 (FIG. 7c).

15c shows the two fitting parts 17a, 17b in the second end position.

To lock the second end position, the joint axis 16, which connects the two drive levers 15a, 15b to one another, can be moved into an over-center position.

In other words, the joint axis 16 is located in the second end position of the fitting parts 17a, 17b below an imaginary connecting line 51, which connects the axis of rotation of the drive roller 26b and the joint axis 21 (FIG. 15b) on the second fitting part 17b.

The joint mechanism 12 of the hinge 4a-4d is stable in the second end position due to the joint axis 16 arranged in the over-center position.

[00192] In the over-center position, the first articulated lever 15a always has a tendency to move clockwise when force is applied to the second fitting part 17b. However, this movement is prevented because the two bolts 40a, 40b of the locking lever 38 are at a stop at one end of the control contour 43 of the drive roller 26b and because the second pin 44b of the slide 44 is also at the stop 48 (FIG. 13) of the guide contour 47 of the first fitting part 17a rests.

The locking of the second end position of the fitting parts 17a, 17b is released

a, preferably motor-assisted, rotational movement of the drive roller 26b in the counterclockwise direction is possible.

[00194] Preferably, it can be provided that the two fitting parts 17a, 17b can be releasably locked and/or releasably unlocked in the first end position and/or in the second end position by a movement, in particular a rotary movement, of the drive device 25.

A particular advantage is that the, preferably electric, drive device 25 can be permanently coupled to the drive roller 26b. It is therefore not necessary to couple and decouple the drive device 25 via additional coupling devices.

16a-16c show the arrangement of an oblique joint axis 23 on the first fitting part 17a in different views.

16a shows the base body 36 of the first fitting part 17a, wherein the base body 36 can be placed on the fixed structure 1 via at least one contact surface 36a either directly or via a mounting part 52 (FIG. 13).

The base body 36 of the first fitting part 17a has the guide contour 47 for movable guidance of the slide 44 and/or at least two recesses 53a, 53b for guiding the two bolts 40a, 40b of the locking lever 38 and/or at least one recess 24 for rotatable accommodation a synchronization shaft 10a.

16b shows the base body 36 of the first fitting part 17a in a view from above.

16c shows a cross-sectional view in the direction of the arrows shown in FIG. 16b. It can be seen that the joint axis 23 runs obliquely to at least one contact surface 36a of the first fitting part 17a.

The purpose of the joint axis 23, which is oriented slightly obliquely to a vertical 54, is to support the two support levers 13a, 13b, which are connected to one another via at least one joint axis 14 (FIG. 7c) which runs vertically in the assembled position, during a movement from the first end position to lift the fitting parts 17a, 17b slightly in the direction of the second end position.

When the cover element 2 moves from the first end position flush with the facade, the cover element 2 has a tendency to sag due to gravity.

In order to at least partially compensate for this effect, at least one joint axis 23 of the support levers 13a, 13b is slightly inclined relative to the vertical 54, as a result of which the cover element 2 is raised during a movement from the first end position to the second end position.

The at least one joint axis 23 forms an angle with the vertical 54, the angle being greater than 0° and less than 10°, preferably greater than 0° and less than 5°, particularly preferably greater than 0° and less than 2°, is.

[00205] In an assembled state of the hinge 4a-4d, an upper end of the at least one joint axis 23 is arranged closer to the at least one contact surface 36a of the first fitting part 17a than a lower end of the at least one joint axis 23.

[00206] It can be provided that the at least one joint axis 23 is formed on the first fitting part 17a.

The articulated lever mechanism 12 can comprise at least two support levers 13a, 13b which are articulated to one another via a first hinge axis 14, the support levers 13a, 13b each having a longitudinal direction which is oblique to a normal, at least in the second end position of the fitting parts 17a, 17b the at least one contact surface 36 of the at least one first fitting part 17a runs.

[00208] According to one embodiment it can be provided that an angle between

the longitudinal direction of the support levers 13a, 13b and the normal can be reduced in size in a state loaded by the at least one cover element 2.

In other words, the support levers 13a, 13b are slightly raised by the arrangement of the oblique joint axis 23 during a movement from the first end position to the second end position. This lifting movement of the support levers 13a, 13b can be compensated for by the weight of the cover element 2, so that the cover element 2 essentially assumes a constant height when moving from the closed position into the open position, which is spaced parallel from the stationary structure 1.

It is preferably provided that the articulated lever mechanism 12 has at least one, preferably more than one, further articulated axis 22, 16, 21 (FIG. 7c), which runs parallel to the at least one contact surface 36a of the at least one first fitting part 17a.

17a-17c show a movement of the fitting parts 17a, 17b from the first end position towards the second end position, with the joint axis 23 (not visible here) aligned slightly obliquely relative to a vertical 54 according to the previous FIGS. 16a-16c is.

17a shows the first end position of the fitting parts 17a, 17b relative to one another. It can be seen that the axis of rotation 55 of the roller 19a of the carriage 19 is located slightly below the axis of rotation 56 of the drive roller 26b.

17b shows an intermediate position of the fitting parts 17a, 17b relative to one another between the first end position and the second end position. It can be seen that the support levers 13a, 13b have been raised by the oblique joint axis 23, so that the axis of rotation 55 of the roller 19a and the axis of rotation 56 of the drive roller 26b are now at an identical height.

17c shows a further position of the fitting parts 17a, 17b relative to one another. It can be seen that the support levers 13a, 130 are further raised by the oblique joint axis 23, so that the axis of rotation 55 of the roller 19a is now above the axis of rotation 56 of the drive roller 26b. This lifting movement of the support levers 13a, 13b can be compensated for by the weight of the cover element 2, so that the cover element 2 can always be guided at a constant height when moving between the two end positions.
