Abstract

The invention relates to a door (10) or a window with at least two wings (14a, b). Each of the at least two wings (14a, b) has a connecting rod arrangement (18a). A first connecting rod arrangement (18a) preferably comprises a locking pin (20) with an enlarged end section. A second drive rod assembly preferably includes a locking piece (22) for receiving the enlarged end portion. The first connecting rod arrangement (18a) is designed in particular to move the widened end section towards the second wing (14b) when the first wing (14a) is moved from the closed position to the sliding position. The first wing (14a) is preferably moved the same distance but in the opposite direction during this movement. The second connecting rod arrangement is designed in particular to move the closing piece (22) towards the first wing (14a) when the second wing (14b) is moved from the closed position into the sliding position. The second wing (14b) is preferably moved the same distance but in the opposite direction during this movement. The distance that the first wing (14a) can be moved from the closed position to the sliding position preferably corresponds to the distance that the second wing (14b) can be moved from the closed position to the sliding position.

Description

Background of the Invention

The invention relates to a window or a door with at least two slidable wings which, when closed, overlap transversely to their main planes. The invention also relates to a method for opening such a window or such a door.

the EP 0 546 336 A1 discloses a closure for sliding windows or sliding doors. The closure has a movable closing part on the front side of a sash of the sliding window or the sliding door.

From the WO 2012/093382 A1 a window or door has become known which has two sliding wings. The wings can be locked to the fixed frame by means of a locking device (“locking mechanism 180”). An inter-panel seal 145 may be provided between the wings.

the EP 3 192 951 A1 discloses a sliding door with a door leaf, in particular one that can be raised. A displaceable bolt for gripping behind a closing part on the fixed frame is provided on the front side of the door leaf in order to lock the door leaf on the fixed frame.

From the EP 2 682 545 A1 discloses a locking arrangement for locking a slidable wing against a fixed panel. The locking arrangement has a sliding locking bolt which can engage in a fixed locking part.

the DE 29 29 776 A1 discloses a locking mechanism for sliding doors or sliding windows with two sliding panels. A lever is provided on a sliding leaf. By pivoting the lever, it latches onto a pivotable locking part on the other sliding sash. The pivoting of the lever and the pivoting of the closing part each cause a displacement of the respective sliding sash transversely to the sliding direction. Pivoting the lever thus causes both sliding leaves to be locked at the same time.

From the DE 10 2018 110 603 A1 a mishandling device for sashes of a window or door that can be pushed together at the front has become known.

the EP 2 860 333 A1 discloses a locking arrangement for locking two sliding leaves. The closure arrangement can each have a claw that can be displaced perpendicularly to the plane of the wing on the end faces of the sliding wing.

An arrangement of two overlapping sashes has become known from the product catalog of Aug. Winkhaus GmbH & Co. KG "duoPort SK - The sliding tilt fitting", as of: 05/2013, August-Winkhaus-Strasse 31, 48291 Telgte. Both wings are parked in the same direction. Therefore, in order to open the arrangement, one wing must first be parked, then the other wing can be parked.

object of the invention

In contrast, the object of the invention is to provide a window or a door with at least two sliding leaves which can be connected to one another both intuitively and tightly independently of one another. It is a further object of the invention to provide a method for opening such a window or such a door.

Description of the invention

This object is achieved according to the invention by a window or a door according to claim 1 and a method according to claim 14. The dependent claims reflect preferred developments.

1. a) Einen festen Rahmen;
2. b) einen ersten Flügel, der aus einer Schließstellung in Richtung quer zu seiner Hauptebene in eine Schiebestellung bewegbar ist, wobei er in der Schiebestellung in Richtung seiner Hauptebene verschiebbar ist;
3. c) einen zweiten Flügel, der aus einer Schließstellung in Richtung quer zu seiner Hauptebene in eine Schiebestellung bewegbar ist, wobei er in der Schiebestellung in Richtung seiner Hauptebene verschiebbar ist;
4. d) eine Überlappung der Flügel, wenn sich beide in der Schließstellung befinden;
5. e) eine erste Treibstangenanordnung und einen damit gekoppelten ersten Griff am ersten Flügel, um den ersten Flügel durch eine Betätigung des ersten Griffs unabhängig vom zweiten Flügel in die Schiebestellung zu bewegen;
6. f) eine zweite Treibstangenanordnung und einen damit gekoppelten zweiten Griff am zweiten Flügel, um den zweiten Flügel durch eine Betätigung des zweiten Griffs unabhängig vom ersten Flügel in die Schiebestellung zu bewegen;
7. g) einen Schließzapfen an der ersten Treibstangenanordnung, der quer zur Hauptebene des ersten Flügels bewegbar ist;
8. h) ein vom Schließzapfen hintergreifbares Schließstück an der zweiten Treibstangenanordnung, das quer zur Hauptebene des zweiten Flügels bewegbar ist.

The object according to the invention is thus achieved by a window or a door, the window or the door having the following:

1. a) A solid framework;
2. b) a first wing movable from a closed position in a direction transverse to its main plane to a sliding position, in which sliding position it is slidable in the direction of its main plane;
3. c) a second wing movable from a closed position in a direction transverse to its main plane to a sliding position, in the sliding position it being slidable in the direction of its main plane;
4. d) an overlap of the leaves when both are in the closed position;
5. e) a first connecting rod assembly and a first handle coupled thereto on the first wing for moving the first wing to the sliding position independently of the second wing by operation of the first handle;
6. f) a second drive rod assembly and a second handle coupled thereto on the second wing to independently operate the second wing by actuation of the second handle move the first wing to the sliding position;
7. g) a locking pin on the first connecting rod assembly which is movable transversely to the main plane of the first wing;
8. h) a locking piece that can be gripped from behind by the locking pin on the second connecting rod arrangement, which is movable transversely to the main plane of the second wing.

The arrangement of the at least two wings overlapping in the closed position is also referred to as “scheme D”. The locking pin and locking piece elements, which can be moved independently of one another according to the invention, allow intuitive operation (opening and closing or connecting) of the two leaves.

The locking pin and/or the locking piece can preferably be moved perpendicularly to the main plane of the respective wing.

The closing piece can have a through-hole, in particular a slot-shaped or Ω-shaped through-hole. The through-hole can have a recess into which a widened, in particular mushroom-shaped, end section of the locking pin engages in the closed position of both wings, so that the wings can no longer be displaced. This achieves a particularly burglar-proof locking of the two wings to one another. Preferably, the widened end portion engages the recess only when both wings are in the closed position. In all other positions, the widened end section preferably does not engage in the recess, so that the wing(s) can be moved in the sliding position.

The first wing may include a first slider unit. The first slide unit can have a first slide with a first connecting link. The first link can run at least in sections obliquely to the longitudinal axis of a first drive rod. The first connecting rod can be made in one piece or in several pieces. A first bolt, which is arranged or formed on the first connecting rod, can be guided in the first connecting link. The locking pin can be arranged or formed on the first slide. A displacement of the first connecting rod in the direction of its longitudinal axis can thereby cause a movement of the locking pin transversely, in particular perpendicularly, to this longitudinal axis.

The second wing may include a second slide assembly. The second slide unit can have a second slide with a second connecting link. The second link can run at least in sections obliquely to the longitudinal axis of a second drive rod. The second connecting rod can be made in one piece or in several pieces. A second bolt, which is arranged or formed on the second drive rod, can be guided in the second connecting link. The closing piece can be arranged or formed on the second slide. A displacement of the second connecting rod in the direction of its longitudinal axis can cause a movement of the closing piece transversely, in particular perpendicularly, to this longitudinal axis.

The first slide unit and the second slide unit are preferably of identical design. By using identical parts, the window or the door can be constructed in a particularly simple and cost-effective manner.

The second wing may have a third slider unit. The third slide unit can have a third slide with a third connecting link. The third link can run at least in sections obliquely to the longitudinal axis of the second drive rod. A third bolt, which is arranged or formed on the second connecting rod, can be guided in the third connecting link. The closing piece can be arranged or formed on the third slide. The third slider can be connected to the second slider via the closing piece. A displacement of the second connecting rod in the direction of its longitudinal axis can thereby bring about a particularly reliable and tilt-free movement of the closing piece transversely, in particular perpendicularly, to this longitudinal axis.

The second slide unit and the third slide unit are preferably of identical design.

The first connecting rod arrangement can have a carriage on the underside of the first wing, through which the first wing can be moved transversely, in particular perpendicularly, to its main plane.

The mobility of the underside of the first wing preferably corresponds to the mobility of the locking pin, in particular minus the immersion depth of the widened end section of the locking pin in the recess of the locking piece, in the opposite direction.

The carriage can have a slider with a link in which a bolt is guided, which is arranged or formed on a connecting rod of the first connecting rod arrangement. At least one roller of the carriage can be arranged on the slide, which is supported relative to the fixed frame, in particular a running rail of the fixed frame. The backdrop can be the same or be designed as a mirror image of the first backdrop.

The second connecting rod arrangement can have a carriage on the underside of the second wing, through which the second wing can be moved transversely, in particular perpendicularly, to its main plane.

The movability of the underside of the second wing preferably corresponds to the movability of the closing piece, in particular minus the immersion depth of the widened end section of the locking pin in the recess of the closing piece, in the opposite direction. The movability of the underside of the second wing particularly preferably corresponds to the movability of the underside of the first wing.

The carriage can have a slider with a link in which a bolt is guided, which is arranged or formed on a connecting rod of the second connecting rod arrangement. At least one roller of the carriage can be arranged on the slide, which is supported relative to the fixed frame, in particular a running rail of the fixed frame. The backdrop can be the same or a mirror image of the first backdrop.

The first connecting rod arrangement can have a slide on the upper side of the first wing, by means of which the first wing can be moved transversely, in particular perpendicularly, to its main plane. The slider can have a roller with which it is supported on the fixed frame and rolls along it.

The mobility of the upper side of the first wing preferably corresponds to the mobility of the locking pin, in particular minus the immersion depth of the widened end section of the locking pin in the recess of the locking piece, in the opposite direction. The movability of the upper side of the first wing particularly preferably corresponds to the movability of the underside of the first wing.

The slider can have a slider with a link in which a bolt is guided, which is arranged or formed on a connecting rod of the first connecting rod arrangement. The slide can be supported directly or indirectly with respect to the fixed frame. The backdrop can be the same or a mirror image of the first backdrop.

The second connecting rod arrangement can have a slide on the upper side of the second wing, by means of which the second wing can be moved transversely, in particular perpendicularly, to its main plane.

The mobility of the upper side of the second wing preferably corresponds to the mobility of the closing piece, in particular minus the immersion depth of the widened end section of the locking pin in the recess of the closing piece, in the opposite direction. The movability of the upper side of the second wing particularly preferably corresponds to the movability of the underside of the second wing.

The slider can have a slide with a connecting link in which a bolt is guided, which is arranged or formed on a connecting rod of the second connecting rod arrangement. The slide can be supported directly or indirectly with respect to the fixed frame. The backdrop can be the same or a mirror image of the first backdrop.

The carriages and/or gliders described above enable the two wings to be arranged in any desired closed or sliding positions without any collisions.

In a further preferred embodiment of the invention, the window or door on the fixed frame has a sealing web between the first wing and the second wing, against which the first wing rests in its closed position and on the opposite side of which the second wing rests in its closed position. This achieves a very reliable sealing of the window or door.

The sealing web is particularly preferably arranged or formed circumferentially on the fixed frame, but at least on the upper and lower horizontal beam of the fixed frame.

A sealing strip can be arranged on one or both wings in the overlapping area of the closed wings in order to seal between the two wings. The same sealing strips can be used on both wings. The sealing strips of the two wings can touch each other and thus form a common seal in the area between the wings. However, a sealing strip can also be used on one or both wings, which seals directly on the profile of the other wing. Together with the sealing web on the fixed frame, this creates a circumferential sealing level that seals particularly well because there is no sealing misalignment.

Any gap between the fixed frame and the overlapping area of the closed sashes can be closed by fittings designed as sealing cushions.

1. A) Verschwenken des ersten Griffs und dadurch Bewegen des Schließzapfens mittels der ersten Treibstangenanordnung quer, insbesondere senkrecht, zur Hauptebene des ersten Flügels;
2. B) Verschwenken des zweiten Griffs und dadurch Bewegen des Schließstücks quer, insbesondere senkrecht, zur Hauptebene des zweiten Flügels; wobei die Verfahrensschritte nur je einzeln für sich, nacheinander in beliebiger Reihenfolge oder gleichzeitig durchgeführt werden;
3. C) Verschieben des ersten Flügels und/oder zweiten Flügels.

The object of the invention is also achieved by a method for opening a window described here or a door described here with the method steps:

1. A) Pivoting the first handle and thereby moving the locking pin by means of the first connecting rod arrangement transversely, in particular perpendicularly, to the main plane of the first wing;
2. B) Pivoting the second handle and thereby moving the closing piece transversely, in particular perpendicularly, to the main plane of the second wing; the process steps being carried out only individually, one after the other in any order or simultaneously;
3. C) Moving the first wing and/or second wing.

The first wing is particularly preferably moved in method step A) by the same amount, in particular minus the immersion depth of the widened end section of the locking pin in the recess of the locking piece, as the locking pin, but in the opposite direction.

More preferably, the second wing is moved in method step B) by the same amount, in particular minus the immersion depth of the widened end section of the locking pin in the depression of the locking piece, as the locking piece, but in the opposite direction.

Further advantages of the invention result from the description and the drawing. Likewise, the features mentioned above and those detailed below can be used according to the invention individually or collectively in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

1 shows a door 10 with a fixed frame 12, a first wing 14a and a second wing 14b. The first wing 14a has a first handle 16a connected to a first connecting rod assembly 18a. The first connecting rod arrangement 18a has a locking pin 20 . The locking pin 20 is used to lock on a locking piece 22 of the second wing 14b.

2 shows the door 10 out 1 with pivoted first handle 16a. The pivoting of the first handle 16a causes a movement of the locking pin 20 by means of the first drive rod arrangement 18a. The first wing 14a is positively controlled by the pivoting of the first handle 16a from its in 1 to the closed position shown in 2 shift position shown moved.

3 shows the door 10 with the first wing 14a and the second wing 14b from the opposite side. Out of 3 It can be seen that the second wing 14b has a second handle 16b connected to a second connecting rod assembly 18b.

4 shows the door 10 out 3 with pivoted second handle 16b. The pivoting of the second handle 16b causes the closing piece 22 to move by means of the second connecting rod arrangement 18b. The second leaf 14b is positively controlled out of its in position by the pivoting of the second handle 16b 3 to the closed position shown in 4 shift position shown moved.

5 shows part of the first drive rod arrangement 18a with a first drive rod 24a and a first slide unit 26a. The first slide unit 26a has a first slide 28a with the locking pin 20 . The first slide 28a has a first connecting link 30a which runs at least in sections obliquely to the longitudinal axis of the first connecting rod 24a and in which a first bolt 32a arranged or formed on the first connecting rod 24a is guided. A movement of the first connecting rod 24a causes a movement of the locking pin 20 transversely, in particular perpendicularly, to the longitudinal axis of the first connecting rod 24a. It goes without saying that this movement of the locking pin 20 can also be achieved by a different implementation of the movement of the first drive rod 24a, for example by a gear.

The locking pin 20 has a broadened, in particular mushroom-shaped, end section 34 . The locking pin 20 is in a through hole 36 by moving the wings 14a, b (see 1 ) retractable and extendable. In an optional embodiment, the movement of the locking pin 20 in the direction of its longitudinal axis allows the end section 34 to move in and out of a recess (at 38) in the locking piece 22 .

6 shows part of the second drive rod arrangement 18b with a second drive rod 24b and a second slide unit 26b. The second slide unit 26b has a second slide 28b with the closing piece 22 . The second slide 28b has a second connecting link 30b which runs at least in sections obliquely to the longitudinal axis of the second connecting rod 24b and in which a second bolt 32b arranged or formed on the second connecting rod 24b is guided. A movement of the second connecting rod 24b causes a movement of the closing piece 22 transversely, in particular perpendicularly, to the longitudinal axis of the second connecting rod 24b. It goes without saying that this movement of the closing piece 22 can also be achieved by a different implementation of the movement of the second drive rod 24b, for example by a gear.

In the present example, the second drive rod arrangement 18b has a third slide unit 26c with a third slide 28c on the closing piece 22 in order to be able to move the closing piece 22 in and out evenly and without tilting. The third slide 28c has a third connecting link 30c which runs at least in sections obliquely to the longitudinal axis of the second connecting rod 24b and in which a third bolt 32c arranged or formed on the second connecting rod 24b is guided. It goes without saying that the second bolt 32b and the third bolt 32c can be arranged or formed on sections of the second connecting rod 24b, these sections being coupled in terms of movement.

7 shows the door 10 in a sectional plan view. Both the first wing 14a and the second wing 14b are in their closed position. In this closed position, the first leaf 14a is at a large distance Ag from the outside of the fixed frame 12. The second wing 14b also has a large distance Bg to the outside of the fixed frame 12. The locking pin 20 and the locking piece 22 meet at a distance SE (closing plane) to the fixed frame 12. Off 7 it can be seen that the wings 14a, b partially overlap in the area of the locking pin 20 and the locking piece 22.

8th shows the door 10 according to FIG 7 , wherein the first wing 14a is in the sliding position. In this case, the first wing 14a has a small or reduced distance Ak from the outside of the fixed frame 12 . The second wing 14b still has the large distance Bg to the outside of the fixed frame 12. The locking pin 20 and the locking piece 22 continue to meet at the distance SE from the fixed frame 12. Thus, although the first wing 14a has been moved towards the outside of the fixed frame 12, at the same time the locking pin 20 has been moved away from the fixed frame 12 by the same length, so that the distance SE remains the same (unless the locking pin 20 is in a recess (at 38; see 5 ) of the closing piece 22 was immersed).

9 shows the door 10 according to FIG 8th , the second wing 14b being in the sliding position. The second wing 14b has a small or reduced distance Bk to the outside of the fixed frame 12. The first wing 14a has the large distance Ag to the outside of the fixed frame 12. The locking pin 20 and the locking piece 22 continue to meet at the distance SE from the fixed frame 12. Thus, although the second wing 14b has been moved towards the outside of the fixed frame 12, at the same time the locking piece 22 has been moved away from the fixed frame 12 by the same length, so that the distance SE remains the same (unless the locking pin 20 is in a recess (at 38; see 5 ) of the closing piece 22 was immersed).

10 shows the door 10 with both leaves 14a, b in the sliding position, ie with a small distance Ak or Bk to the fixed frame 12. The distance SE in the area of the locking pin 20 or locking piece 22 also remains the same in this case. In the sliding position, the wings 14a, b can each be displaced in the direction of their main plane H. The main plane H is the central plane of the frame of the respective wing 14a,b. The dimensions Ag (see 9 ), Ak, Bg (see 8th ), Bk and SE are measured perpendicular to the principal plane H.

A synopsis of 7 and 10 shows that when the first leaf 14a is displaced from the distance Ag to Ak by the distance Ag-Ak, the locking pin 20 is also displaced by the distance Ag-Ak, but in the opposite direction. Furthermore, it can be seen that when the second wing 14b is displaced from the distance Bg to Bk by the distance Bg-Bk, the locking piece 22 is also displaced by the distance Bg-Bk, but in the opposite direction. The distance Ag-Ak particularly preferably corresponds to the distance Bg-Bk.

In 10 Optional seals 40a, 40b on wings 14a, b are shown in phantom. The seals 40a, b serve to seal the wings 14a, b from one another in their overlapping area or at the mullion 42. The seals 40a, b are preferably of identical design and/or arranged symmetrically to one another. They can each have a seal receptacle 44a, 44b and a sealing strip 46a, 46b arranged or formed thereon.

11 shows the door 10 with the wings 14a, b in the closed position. Out of 11 it can be seen that the wings 14a, b are supported on the underside by carriages 48a, 48b and on the upper side by sliders 50a, 50b relative to the fixed frame 12. Carriages 48a,b and sliders 50a,b are positively controlled with the drive rod assemblies 18a,b (see 5 , 6 ) for moving the wings 14a, b connected from the closed position to the sliding position. In the closed position, the wings 14a, b rest against a sealing web 52 of the fixed frame 12. In the overlapping area of the two wings 14a, b, optional seals 40a and 40b can be seen, which here - unlike in 10 - Touch each other and thus form a common seal in the area between the wings 14a, b.

12 shows the door 10 according to FIG 11 , with the wings 14a, b being in the sliding position. In this position, the wings 14a, b are not in contact with the sealing web 52. The sealing web 52 is parallel to and centered between the main planes H (see 10 ). The sealing web 52 is also preferably located centrally in the door 10 and preferably forms a vertical plane of symmetry.

13 shows a door 10 according to FIG 7 with the fixed frame 12, the wings 14a, b, seals 40a, b and the sealing web 52, the seals 40a, b with the sealing web 52 each forming an offset sealing plane.

Taking all the figures of the drawing together, the invention relates in summary to a door 10 or a window with at least two wings 14a, b. Each of the at least two wings 14a, b has a connecting rod arrangement 18a, b. A first connecting rod assembly 18a preferably includes a locking pin 20 having an enlarged end portion 34. A second connecting rod assembly 18b preferably includes a locking piece 22 for receiving the enlarged end portion 34. The first connecting rod assembly 18a is specifically configured to lock the enlarged end portion 34 upon movement of the first wing 14a to move from the closed position to the sliding position towards the second wing 14b. The first wing 14a is preferably moved the same distance but in the opposite direction during this movement. The second connecting rod arrangement 18b is designed in particular to move the closing piece 22 towards the first wing 14a when the second wing 14b is moved from the closed position into the sliding position. The second vane 14b is preferably moved the same distance but in the opposite direction during this movement. The distance that the first wing 14a is moveable from the closed position to the sliding position preferably corresponds to the distance that the second wing 14b is moveable from the closed position to the sliding position.
