Window or door with a center closer between two sashes

Abstract

The invention relates to a window or door (10) with two sashes (14a, 14b) which are slidable in their sliding position in the direction of their main plane (16a, 16b). Only in the closed position of both sashes (14a, 14b) are they held together in the area of ​​a central break (26) of the door (10) by means of a fitting arrangement (24). A drive rod arrangement (20a, 20b) is arranged on each sash (14a, 14b), to which a locking element (22a, 22b) is movably connected. In the closed position of both sashes (14a, 14b), the locking elements (22a, 22b) preferably engage in such a way that the sashes (14a, 14b) are immovable relative to each other, at least transversely to their main planes (16a, 16b), and thus provide a particularly good seal against each other.Preferably, the locking elements (22a, 22b) interlock in the closed position of both leaves (14a, 14b) such that the leaves (14a, 14b) cannot be moved in the direction of their main plane (16a, 16b) in order to provide improved burglary protection. The locking elements (22a, 22b) can each be connected to a drive rod assembly (20a, 20b) via a deflected connector (56a, 56b). At least one locking element (22a, 22b) is movable and / or pivotable in the direction of the main plane (16a, 16b) of the respective leaf (14a, 14b). This allows the leaf mullions (66a, 66b) to preferably overlap at least to a large extent in the closed position of both leaves (14a, 14b), which is visually very appealing. The invention further relates to a method for opening the window or door (10).

Description

Background of the invention

[0001] The invention relates to a window or door with the following features: a) within a fixed framework; b) a first wing which can be moved from its closed position transversely to its main plane into its sliding position and which, in the sliding position, can be moved in the direction of its main plane; c) a second wing which can be moved from its closed position transversely to its main plane into its sliding position and which, in the sliding position, can be moved in the direction of its main plane; d) wherein the wings partially overlap in the direction of view perpendicular to the main plane of the first wing when both wings are in their closed position; e) a first connecting rod arrangement on the first wing, wherein the first wing can be moved from its closed position to its sliding position independently of the second wing by actuating the first connecting rod arrangement; f) a second connecting rod arrangement on the second wing, wherein the second wing can be moved from its closed position to its sliding position independently of the first wing by actuating the second connecting rod arrangement; (g) a first locking element on the first wing, which is arranged towards the second wing when both wings are in the closed position, wherein the first locking element is coupled to the first drive rod assembly and is movable relative to the first wing, wherein the first locking element is positively connected to a second locking element in the closed position of both wings; h) the second locking element on the second wing, which is arranged towards the first wing when both wings are in the closed position, wherein the second locking element is coupled to the second drive rod arrangement and is movable relative to the second wing, wherein the second locking element is positively connected to the first locking element in the closed position of both wings.

[0002] The invention further relates to a method for opening such a window or door.

[0003] A previously described window, a previously described door, and a previously described method are known from DE 10 2021 211 638 B3. The locking elements disclosed therein are both movable transversely to the main planes of the sashes. However, a disadvantage of the known locking elements is that the two sashes, in particular adjacent vertical sash mullions of the two sashes, hardly overlap in their closed position. Since the sashes typically have panes set in sash frames, the barely overlapping sash mullions occupy a large proportion of the total surface area of ​​the window or door in the closed position. In particular, sash mullions that barely overlap at the central pivot appear visually very wide. Object of the invention

[0004] It is therefore an object of the invention to provide a window, a door and a method that enable a significantly more visually attractive view of the central break in sashes in the closed position and preferably still enable a stable connection of sash mullions. Description of the invention

[0005] This problem is solved according to the invention by a window or a door according to claim 1 and a method according to claim 15. The dependent claims describe preferred embodiments.

[0006] The window or door according to the invention thus has / have the following feature(s): i) the first locking element is activated by actuating the first connecting rod assembly i. movable parallel to the main plane of the first wing; and / or ii. swiveling; where the first locking element is no longer positively connected to the second locking element in the sliding position of the first wing; and / or j) the second locking element is activated by actuating the second connecting rod assembly i. movable parallel to the main plane of the second wing; and / or ii. swiveling; where the second locking element is no longer positively connected to the first locking element in the sliding position of the second wing.

[0007] The first locking element, which is movable and / or pivotable parallel to the main plane of the first sash, preferably linearly, allows for a particularly space-saving arrangement of the two locking elements between the sashes, especially between the sash mullions of the two sashes. Alternatively or additionally, the second locking element is movable and / or pivotable parallel to the main plane of the second sash, preferably linearly. This allows the sash mullions to overlap particularly well, giving the window or door a visually light appearance.

[0008] In the closed position of both leaves, the two locking elements are positively locked against each other; the two locking elements interlock. An interlock is understood to mean, in particular, that the locking elements are positively locked against each other in the direction of movement perpendicular to the main planes of the leaves; the leaves cannot be pulled apart perpendicular to their main planes. Preferably, with the interlock, the locking elements are held positively locked against each other in such a way that the leaves cannot be moved further towards each other in the direction of their main planes, thus preventing further overlap.

[0009] If even one of the leaves is in the sliding position, the two locking elements are no longer held securely together and the two leaves can be moved relative to each other.

[0010] The window or door is preferably designed without a strut of the fixed frame at the central break. The design of the window or door according to the invention is referred to in particular as "Scheme D" or "opposing sliding sashes on two parallel guide rails".

[0011] The first locking element can be moved transversely to the main plane of the first leaf by actuating the first connecting rod assembly. Alternatively, the second locking element can be moved transversely to the main plane of the second leaf by actuating the second connecting rod assembly. However, at least one of the two locking elements is designed to be movable and / or pivotable within the main plane of its corresponding leaf. The first locking element, together with the second locking element, can form a central closing mechanism between the leaves.

[0012] In a preferred embodiment of the invention, the first locking element is movable horizontally and / or vertically by means of the first drive rod arrangement. Alternatively or additionally, the second locking element can be moved horizontally and / or vertically by means of the second drive rod arrangement.

[0013] Terms like "vertical", "horizontal", "top", "bottom", etc. generally refer to the installed position of the window or door. The positions of the sashes (closed position / sliding position) refer analogously to the positions of the locking mechanisms.

[0014] To significantly simplify the design of the window or door, the first and second locking elements can be designed to be movable only vertically.

[0015] A structurally simple design of the window or door can still be achieved if the two drive rod arrangements in the area of ​​the closing elements are moved parallel to each other in the same direction or in opposite directions.

[0016] Preferably, both the first locking element and the second locking element can be moved downwards or both upwards from the closed position to the sliding position. Alternatively, one of the locking elements can be moved upwards from the closed position to the sliding position, and the other locking element can be moved downwards from the closed position to the sliding position.

[0017] The first sash can have a first sash mullion and the second sash can have a second sash mullion, with both sash mullions overlapping by more than 40% when the sashes are closed. More preferably, the two sash mullions overlap by more than 60%, and particularly preferably by more than 80%. This results in a visually appealing appearance of the window or door as well as a reliable seal between the two sashes.

[0018] In one embodiment of the locking elements, the first locking element can be in the form of a locking pin and the second locking element in the form of a locking piece to receive the locking pin in the closed position of the wings.

[0019] The locking bolt is preferably mushroom-shaped. More preferably, the strike plate can have an elongated hole and / or a groove with an Ω-shaped cross-section, which is engaged by a mushroom-headed section of the locking bolt when both leaves are closed. An Ω-shaped groove is understood to have a constriction on the opening side. The elongated hole and / or the Ω-shaped groove can extend vertically to ensure precise, exclusively vertical movement of the locking bolt and the strike plate.

[0020] The strike plate may have an insertion ramp that rises perpendicular to the main plane of the second sash to facilitate the insertion of the locking bolt. Alternatively or additionally, the strike plate may have an insertion ramp that rises in a plane parallel to the main plane of the second sash to facilitate the insertion of the locking bolt.

[0021] A guide element can be provided on the second sash to guide the locking mechanism. This guide element is preferably plate-shaped. Attaching the guide element to the second sash, preferably to the sash reinforcement, results in high stability and burglar resistance, as the two sashes are thereby firmly connected to each other perpendicular to their main sash planes.

[0022] A cam guide can be provided to guide the locking piece on the guide element.

[0023] At the central break, many tolerances of the window or door typically accumulate. To compensate for these tolerances, the guide element and / or the strike plate can be attached to the second sash with limited horizontal movement. Preferably, the guide element and / or the strike plate has / have an elongated hole in which a bolt and / or screw is / are guided to allow this horizontal movement.

[0024] In a further preferred embodiment of the invention, the first locking element and the second locking element are each designed in a hook shape. This simplifies the manufacturing of the locking elements. Even more preferably, the locking elements are identical.

[0025] One locking element can have a projection that, in the closed position of the sashes, engages in a recess of the other locking element. More preferably, both locking elements each have at least one projection and one recess, wherein, in the closed position of the sashes, a projection of one locking element engages in the recess of the other locking element and vice versa.

[0026] In order to compensate for tolerances, especially horizontal tolerances, the recess(s) can each be designed in the form of an elongated groove or a slot.

[0027] The first drive rod assembly is preferably arranged on the end face of the first wing, i.e., pointing in the sliding direction of the first wing. In this case, the first locking element can be connected to the first drive rod assembly via a deflected connector. A deflected connector is understood to be, in particular, any shape that allows the first drive rod assembly to be connected horizontally to the first locking element on an end face of the first wing, especially an angle or a bent element.

[0028] The second drive rod assembly is preferably arranged on the end face of the second wing, i.e., pointing in the sliding direction of the second wing. In this case, the second locking element can be connected to the second drive rod assembly via a deflected connector. A deflected connector is understood to be, in particular, any shape that allows the second drive rod assembly on an end face of the second wing to be connected to the second locking element horizontally, especially an angle or a bent element.

[0029] A first retaining element can be arranged on the first door leaf to assist in holding the first locking element in the closed position. Alternatively or additionally, a second retaining element can be arranged on the second door leaf to assist in holding the second locking element in the closed position. The first retaining element and / or the second retaining element can be L-shaped or U-shaped. Preferably, the first retaining element and / or the second retaining element is / are designed in the form of a guide plate.

[0030] The first connecting rod assembly can have a first carriage on the underside of the first wing, by which the first wing is movable transversely, in particular perpendicularly, to its main plane. The first carriage can have a carriage slide with a cam in which a bolt is guided, which is arranged or formed on a connecting rod of the first connecting rod assembly. A roller of the carriage can be arranged on the carriage slide, which bears against the fixed frame, in particular a guide rail of the fixed frame.

[0031] The first connecting rod assembly can have a first slider on the upper surface of the first wing, by which the first wing is movable transversely, in particular perpendicularly, to its main plane. The first slider can have a roller with which it is supported against the fixed frame and rolls along it. The first slider can have a slider slide with a cam in which a bolt is guided, which is arranged or formed on a connecting rod of the first connecting rod assembly. The slider slide can be supported indirectly or directly against the fixed frame.

[0032] The second connecting rod assembly can have a second carriage on the underside of the second wing, by which the second wing is movable transversely, in particular perpendicularly, to its main plane. The second carriage can have a carriage slide with a cam in which a bolt is guided, which is arranged or formed on a connecting rod of the second connecting rod assembly. A roller of the carriage can be arranged on the carriage slide, which bears against the fixed frame, in particular a guide rail of the fixed frame.

[0033] The second connecting rod assembly can have a second slider on the upper surface of the second wing, by which the second wing is movable transversely, in particular perpendicularly, to its main plane. The second slider can have a roller with which it is supported against the fixed frame and rolls along it. The second slider can have a slider slide with a cam in which a bolt is guided, which is arranged on or formed on a connecting rod of the second connecting rod assembly. The slider slide can be supported indirectly or directly against the fixed frame.

[0034] The drive rod assemblies can each be coupled to a handle for operating them. The window or door is preferably designed such that the sashes, from their closed position, are not yet moved transversely to their main planes during the first 30%, particularly the first 40%, preferably the first 50%, of the maximum handle movement. This allows the locking elements to disengage before the sashes are moved apart. The aforementioned free play of the drive rod assemblies can be achieved, for example, by a long, straight section of the cams of the carriage slides and / or the sliding slides extending longitudinally along the drive rod assembly.

[0035] The problem according to the invention is further solved by a method for opening a window or door described herein, comprising the following method steps: A) Actuating the first connecting rod assembly, in particular with the first handle, to move the first sash from its closed position to its sliding position, thereby releasing the positive locking of the first locking element with the second locking element; and / or B) Actuating the second drive rod assembly, in particular with the second handle, to move the second wing from its closed position to the sliding position, thereby releasing the positive locking of the second locking element with the first locking element.

[0036] Further advantages of the invention will become apparent from the description and the drawing. Likewise, the features mentioned above and those described in more detail below can each be used individually or in any combination according to the invention.

[0038] Fig. Figure 1a shows a door 10 with a fixed frame 12, a first leaf 14a, and a second leaf 14b. The extent of the first leaf 14a defines its main plane 16a, and the extent of the second leaf 14b defines its main plane 16b. In Fig. 1a both wings 14a, 14b are in their closed position; the door 10 is closed.

[0039] The leaves 14a, 14b can each be moved independently of one another into their sliding position by a movement transverse to their respective main plane 16a, 16b and can be moved in the direction of their respective main plane 16a, 16b in order to open the door 10. In the illustrated embodiment, the movement of the leaves 14a, 14b takes place horizontally in front of or behind the respective other leaf 14a, 14b.

[0040] The first wing 14a has a first handle 18a, and the second wing 14b has a second handle 18b. Preferably, the first wing 14a is in its closed position when the first handle 18a points downwards, and the second wing 14b is in its closed position when the second handle 18b points downwards. The first handle 18a is coupled to a first drive rod assembly 20a, and the second handle 18b is coupled to a second drive rod assembly 20b.

[0041] The first drive rod assembly 20a is connected to a first locking element 22a. The second drive rod assembly 20b is connected to a second locking element 22b. The drive rod assemblies 20a, 20b and the locking elements 22a, 22b generally form a fitting assembly 24. The fitting assembly 24 consists of Fig. 1a is enlarged in Fig. 1e is evident.

[0042] The Fig. 1a and Fig. Figure 1e shows that the first locking element 22a is in the form of a locking bolt and the second locking element 22b is in the form of a locking piece. The first locking element 22a is positively engaged with the second locking element 22b.

[0043] Fig. Figure 1b shows the door 10 with the first leaf 14a in the sliding position. The first handle 18a preferably points upwards. The two leaves 14a, 14b are no longer positively engaged at the central break 26. As shown in Figure 1b, the door 10 has the first leaf 14a in the sliding position. The first handle 18a preferably points upwards. The two leaves 14a, 14b are no longer positively engaged at the central break 26. As shown in Figure 1b, the first leaf 14a is no longer positively engaged at the central break 26. As shown in Figure 1b, the first leaf 14a is no longer positively engaged at the central break 26. As shown in Figure 1b, the first leaf 14a is no longer positively engaged at the central break 26. As shown in Figure 1b, the first leaf 14a is no longer positively engaged at the central break 26. As shown in Figure 1b, the first leaf 14a, 14b, ... the first leaf 14a, 14b, is no longer positively engaged at the central break 26. As shown in Figure 1b, the first leaf 14a, 14b, the first leaf 14a, 14b, is no longer positively engaged at the central break 26 Fig. As can be seen in Figure 1f, which shows the fitting arrangement 24, the locking bolt (first locking element 22a) has a mushroom head 28 that no longer engages behind the Ω-shaped groove 30 of the strike plate (second locking element 22b). The vertical movement (here upwards) of the first drive rod arrangement 20a causes a vertical movement (here upwards) of the first locking element 22a.

[0044] Fig. Figure 1c shows door 10 with the second leaf 14b in the sliding position. As seen from Fig. As can be seen in Figure 1g, which shows the fitting arrangement 24, the first locking element 22a with its mushroom head 28 no longer engages the Ω-shaped groove 30 of the second locking element 22b. The vertical movement (here upwards) of the second drive rod arrangement 20b causes a vertical movement (here upwards) of the second locking element 22b.

[0045] The Fig. 1d and Fig. Figure 1h shows the door 10 and the fitting assembly 24, respectively, whereby both drive rod assemblies 20a, 20b were moved vertically, here upwards, by pivoting the handles 18a, 18b. This moved both locking elements 22a, 22b vertically, here upwards. The two leaves 14a, 14b are no longer positively locked to each other in the area of ​​the central break 26.

[0046] The Fig. Figures 1a to 1d show an example of a method according to the invention for opening a window or door 10.

[0047] Fig. 1i shows door 10 according to Fig. 1a with the fixed frame 12 and the sashes 14a, 14b in a longitudinal section. In this case, the sashes 14a, 14b optionally each have a seal 32a, 32b. The first locking element 22a is positively engaged with the second locking element 22b.

[0048] Fig. 1j shows door 10 according to Fig. 1b, wherein from Fig. As can be seen in Figure 1j, both the first locking element 22a is no longer positively engaged with the second locking element 22b and the first wing 14a is also not in good working order compared to Fig. The first connecting rod arrangement 20a is designed such that a pivoting movement of the first handle 18a during pivoting does not result in any movement of the first wing 14a transverse to its main plane 16a, at least up to the first 45°, in particular at least up to the first 60°, preferably at least up to the first 90°. This allows the positive locking of the first locking element 22a on the second locking element 22b to be reliably released by a purely vertical movement before the first wing 14a moves transversely to its main plane 16a.

[0049] Fig. 1k shows door 10 according to Fig. 1c, wherein from Fig. As can be seen in Figure 1k, both the second locking element 22b is no longer positively engaged with the first locking element 22a and the second wing 14b is no longer positively engaged compared to Fig. 1i has made a movement perpendicular to its main plane 16b. The second connecting rod arrangement 20b is designed such that a pivoting movement of the second handle 18b during pivoting does not lead to any movement of the second wing 14b transversely to its main plane 16b, at least up to the first 45°, in particular at least up to the first 60°, preferably at least up to the first 90°. This allows the positive locking of the second locking element 22b on the first locking element 22a to be reliably released by a purely vertical movement before the second wing 14b moves transversely to its main plane 16b.

[0050] Fig. 1l shows door 10 according to Fig. 1d. From Fig. It is evident from Figure 1 that the wings 14a, 14b were both moved transversely, in particular vertically, to their respective main planes 16a, 16b by the operation of the handles 18a, 18b.

[0051] Fig. Figure 1m shows the previously described second locking element 22b on a guide element 34. The second locking element 22b is movable, here vertically, by a cam guide 36 on the guide element 34, and is thus securely fastened. The guide element 34 is attached to the second sash 14b. Preferably, the guide element 34 is movable, here horizontally, by a further cam guide 38, to allow for tolerance compensation.

[0052] Fig. Figure 1n shows the arrangement of the second closing element 22b and the guide element 34 according to Fig. 1m, wherein the second closing element 22b, limited by the cam guide 36 and the further cam guide 38, is maximally opposite to the position according to Fig. is positioned 1m. From a summary of the Fig. 1m and Fig. 1n it is evident that the second locking element 22b is limited in its horizontal and vertical movement on the second wing 14b (see Fig. 1b) is attached.

[0053] Fig. Figure 10 shows a sectional view of the second locking element 22b. From Fig. As can be seen from Figure 10, the second locking element 22b has insertion ramps 40 at least at one end. Preferably, the second locking element 22b has insertion ramps 40, 42 at both ends. This facilitates the insertion of the first locking element 22a into the second locking element 22b (see Figure 10). Fig. 1f).

[0054] The Fig. 1p, Fig. 1q, Fig. 1r and Fig. Figure 1s shows a variant of the arrangement consisting of the second locking element 22b and the guide element 34 according to the Fig. 1m to 10. From the Fig. From 1p to 1s it can be seen that the second closing element 22b is connected to the guide element 34 in a limited manner via both a vertical cam guide 36 and a further horizontal cam guide 38.

[0055] Fig. Figure 2a shows a fitting arrangement 24 with a first locking element 22a and a second locking element 22b for mounting on a door 10 (see Fig. 2e). A first connecting rod arrangement 20a (see Fig. 2e) is provided for actuating a sliding unit 44. The sliding unit 44 has a slide 46 which is movable transversely, in particular vertically, to the main plane 16a of the first wing 14a (see Fig. 2e). The first connecting rod assembly 20a (see Fig. 2e) has a first bolt 48a which is guided in a first cam 50a of the slide 46. The first cam 50a is at least partially inclined to the longitudinal axis 52a of the first connecting rod assembly 20a (see Fig. 2e) in the area of ​​the first bolt 48a. A vertical movement of the first connecting rod assembly 20a (see Fig. 2e) in the area of ​​the first bolt 48a thus leads to a movement, preferably horizontal, of the slide 46 and of the first locking element 22a arranged or formed on the slide 46 transversely to the main plane 16a of the first wing 14a (see Fig. 2e).

[0056] Fig. 2b shows the fitting arrangement 24 from Fig. 2a, wherein the first bolt 48a was moved vertically, here upwards. The first locking element 22a is in the sliding position. The corresponding position of the door 10 is in Fig. 2f shown.

[0057] Fig. Figure 2c shows the fitting arrangement 24 according to Fig. 2a, where the second locking element 22b is now in the sliding position. From Fig. As can be seen in Figure 2c, the first locking element 22a is designed in the form of a locking bolt with a mushroom head 28.
