Description

[0001] The invention relates to a building closure with a door or window arrangement according to the preamble of claim 1. Building closures with such door or

[0002] Window arrangements are well-known in the art. For decades, threshold-based door or window arrangements have been installed, in which a sash has a continuous sash overlap and a frame with a profile with multiple steps to secure and seal the sash relative to the frame when closed. Such door or window arrangements are inexpensive, stable, and have proven themselves in practice. However, such door or window arrangements are not barrier-free and pose a tripping hazard even for people without physical disabilities.

[0003] Barrier-free designs of door or window arrangements are also known, for example, from EP 2 957 702 B1, which shows a design with a so-called zero threshold. This can prevent tripping hazards and achieve a high level of comfort. However, such a design is technically comparatively complex and cost-intensive.

[0004] The invention is based on the object of specifying a building closure with a reduced barrier effect compared to threshold solutions and lower costs compared to a zero threshold.

[0005] The invention solves this problem by a building closure having the features of claim 1.

[0006] The building closure has a door or window arrangement, which in turn has a frame and a sash mounted on the frame and pivotable relative to the frame, preferably towards an outside, between an open position and a closed position.

[0007] The frame has a lower frame cross member extending along a longitudinal direction and the sash has a lower sash cross member with a sash underside facing the frame cross member when the sash is in the closed position.

[0008] The lower frame cross member has a base profile and a (first) cover profile arranged on the base profile. An inner lining borders the lower frame cross member on one inner side.

[0009] The sash is designed without overlap on the underside of the sash, with at least one seal extending along or parallel to the longitudinal direction being arranged on the underside of the sash, which seal is in sealing contact with a surface of the cover profile when the sash is in the closed position.

[0010] The cover profile is adjusted relative to the inner lining such that the surface of the cover profile is arranged along the direction of gravity (g) by a height difference sh of 2 mm < sh < 18 mm (millimeters) above a surface of the inner lining, preferably by a height difference sh of 5 mm < sh < 15 mm, more preferably by a height difference sh of 8 mm < sh < 12 mm.

[0011] The proposed design allows for a building closure with reduced barrier effect using simple structural means. By eliminating the sash overlap on the underside of the sash, the inner lining and the (first) cover profile can be positioned along the direction of gravity with a comparatively small height difference, which may even be considered barrier-free according to DIN 18040. With the proposed design, retractable seals can be dispensed with (door or window arrangement without retractable seals). Furthermore, no complex components are required to create the building closure or the door or window arrangement.

[0012] In other words, the height difference sh between the upper edge of the inner surface and the upper edge of the cover profile lies within the range specified above, with the upper edge of the cover profile positioned above the upper edge of the inner surface along the direction of gravity (cover profile upper edge positioned above inner surface upper edge). Regardless of this, the surface of the (first) cover profile can be designed as a tread surface or tread profile section.

[0013] The seal or seals are preferably arranged in a fixed position relative to the lower wing cross member. In particular, the seal or seals are fixed (directly or indirectly) to the lower wing cross member so that they are immovable along the direction of gravity. The seal or seals are designed, for example, as lip seals, in particular as double-lipped or multi-lipped lip seals.

[0014] Within the scope of a preferred embodiment, the at least one seal can be held in a seal receptacle and fastened by means of the seal receptacle on the underside of the sash to a section of the lower sash cross member which, when the sash is in the closed position, projects towards the inside relative to the lower frame cross member. In other words, the seal(s) or the seal receptacle with seal(s) are arranged on the underside of the sash where the lower sash overlap is located when the sash is in overturning position. This makes it possible to achieve a sufficient sealing effect when the sash is in the closed position. The seal receptacle extends along or parallel to the longitudinal direction. The seal receptacle can have one or two seal receptacle grooves. One seal can be held or fastened in each seal receptacle groove.

[0015] Advantageously, the seal(s) can each have at least one free end, preferably two or more free ends, and can be designed such that the free end(s) of the seal are spaced from the inner lining along the direction of gravity when the sash is pivoted open from the closed position. In other words, the seal(s) are dimensioned such that they do not touch the surface of the inner lining when the sash is pivoted open from the closed position. This prevents damage to the seal(s) and the inner lining. This contributes to a long-term sealing effect.

[0016] The base profile can expediently be arranged and / or configured such that, along the direction of gravity, it is positioned predominantly or entirely below the surface level of the inner lining (adjacent to the lower frame cross member). This contributes to a stable design of the lower frame cross member and a comparatively small height difference between the lower frame cross member and the inner lining.

[0017] In a preferred embodiment, a drainage profile can be mounted on the base profile, wherein the drainage profile is arranged on the side of the (first) cover profile facing away from the interior covering, and wherein a further cover profile is arranged on the drainage profile. This promotes (rain)water drainage on the side of the door or window arrangement facing away from the interior covering, i.e., towards the outside. The drainage profile serves to drain (rain)water. The further cover profile at least partially covers the drainage profile.

[0018] Specifically, an outer covering can be adjacent to the further cover profile on the side of the lower frame cross member facing away from the inner covering, preferably with the surface of the inner covering and the surface of the outer covering having a height difference of between 0 and 2 mm along the direction of gravity. Preferably, the surface of the inner covering and the surface of the outer covering can be at the same height (height difference 0 mm) or, in other words, lie in the same plane. This contributes to a reduced barrier effect.

[0019] The further cover profile can expediently have a (walkable) tread section and a height adjustment section sloping towards the outer covering. This also contributes to a reduced barrier effect. The tread section or tread profile section forms a tread surface for people passing through the door. The height adjustment section enables height adjustment between the tread section and the outer covering. The height adjustment section can have a first partial section that borders on the tread section and a second partial section that borders on the first partial section (towards the outer covering). The first partial section can enclose a first angle with the horizontal and the second partial section can enclose a second angle with the horizontal, wherein the second angle can be greater than the first angle. The second partial section can rest on the outer covering at its end.The surface of the tread section of the additional deck profile and the surface of the (first) deck profile can be at the same height. This allows them to form a single tread plane.

[0020] In a preferred embodiment, the drainage profile and the additional cover profile can define a water drainage channel between them, extending from an inlet (water drainage channel inlet) to an outlet (water drainage channel outlet). This promotes gravity-induced water drainage toward the exterior. The water drainage channel is located between the drainage profile and the additional cover profile and thus (seen from the exterior) in the "lee," allowing gravity-induced water drainage even during precipitation with wind or storms.

[0021] Specifically, the inlet of the water drainage channel can be formed by spacing the end of the additional cover profile facing the (first) cover profile from the (first) cover profile and / or from a section of the drainage profile adjacent to the (first) cover profile. This provides an inlet for the drainage channel using simple structural means. In other words, there is a gap between the end of the additional cover profile facing the (first) cover profile and the (first) cover profile and / or the section of the drainage profile adjacent to the (first) cover profile. The gap can be only a few centimeters wide, e.g., 1-4 cm (centimeters).

[0022] The outlet of the water drainage channel can expediently be formed by a downwardly open drainage section of the additional deck profile in the direction of gravity g, which is arranged between the end of the drainage profile facing away from the (first) deck profile and the outer covering. This allows for sufficient water drainage downwards along the direction of gravity between the lower frame cross member and the outer covering.

[0023] Advantageously, a further seal receptacle extending along or parallel to the longitudinal direction can be arranged on the underside of the wing, with at least one seal extending at the inlet with one or more free ends toward the first cover profile or the drainage profile. This can prevent water from penetrating further than the inlet. The seal(s) are arranged, in particular, above the inlet or on the side of the inlet facing the (first) cover profile.

[0024] Specifically, a weatherboard can be attached to the underside of the sash, which at least partially covers the further cover profile on the outside, at least the tread section of the further cover profile. This promotes (rain)water drainage, since (rain)water that hits the weatherboard does not even reach the area between the underside of the sash and the lower frame cross member, but runs outwards along the weatherboard. The weatherboard is preferably attached to the underside of the sash. The above-mentioned additional seal holder can be attached to the weatherboard or connected to the weatherboard in the same material. The weatherboard can optionally have an additional seal holder extending along or parallel to the longitudinal direction, with at least one seal, which extends with one or more free ends to the further cover profile, in particular at the transition from the tread section to the height adjustment section.

[0025] The invention is explained in more detail below with reference to the figures, in which identical or functionally equivalent elements are provided with identical reference numerals, if necessary, but only once. They show: Fig.1 an embodiment of a building closure with door or window arrangement in a perspective partial view; Fig.2 the building closure from Fig.1 in a sectional view; and Fig.3 another cover profile of the building closure from Fig.1 in a unique position.

[0026] Figur 1 shows a building closure, which is designated overall by the reference number 10.

[0027] The building closure 10 has a door or window arrangement 12 that separates an inner side 14 (building interior) from an outer side 16 (building exterior). The door or window arrangement 12 has a frame 20 and a sash 22 mounted on the frame 20 and pivotable relative to the frame 20, in the example toward an outer side 16, between an open position and a closed position (see FIG. Fig.2 ).

[0028] The frame 20 has a lower frame cross member 24 extending along a longitudinal direction L and the

[0029] Wing 22 has a lower wing cross member 26 with a wing underside 28 facing the lower frame cross member when the wing 22 is in the closed position (cf. Fig.2 ) .

[0030] The lower frame cross member 24 has a base profile 30 and a (first) cover profile 32 arranged on the base profile 30. An inner lining 34 adjoins the lower frame cross member 24 on the inner side 14.

[0031] The wing 22 is designed to be non-overlapping on the wing underside 28, with at least one seal 36 extending along or parallel to the longitudinal direction L being arranged on the wing underside 28, which seal 36, when the wing 22 is in the closed position, is in sealing contact with a surface 32' of the cover profile 32. In the example, the seal 36 is fixed immovably along the direction of gravity g to the lower wing cross member 26 and is designed as a double-lipped lip seal.

[0032] In the example, the cover profile 32 is adjusted relative to the inner covering 34 such that the surface 32' of the cover profile 32 is arranged along the direction of gravity g by a height difference sh of 5 mm < sh < 15 mm above a surface 34' of the inner covering 34. The surface 34' of the cover profile 32 is designed as a tread surface in the example.

[0033] The seal 36 is held in a seal receptacle 38 and, by means of the seal receptacle 38, is fastened to the sash underside 28 at a section 26' of the lower sash cross member 26, which, when the sash 22 is in the closed position, protrudes toward the inner side 14 relative to the lower frame cross member 24. The seal receptacle 38 extends along or parallel to the longitudinal direction L. In the example, the seal receptacle 38 has two seal receptacle grooves 38'.

[0034] In the example, the seal 36 has two free ends 36' and is designed such that the free ends 36' of the seal 36 are spaced from the inner lining 34 along the direction of gravity g when the wing 22 is pivoted out of the closed position.

[0035] In the example, the base profile 30 is arranged and / or designed such that it is arranged along the direction of gravity g predominantly below the height of the surface 34' of the inner lining 34.

[0036] A deflection profile 40 is placed on the base profile 30, wherein the deflection profile 40 is arranged on the side of the cover profile 32 facing away from the inner covering 34, and wherein a further cover profile 42 is arranged on the deflection profile 40.

[0037] On the side of the lower frame cross member 24 facing away from the inner covering 34, an outer covering 44 adjoins the further cover profile 42, wherein the surface 34' of the inner covering 34 and the surface 44' of the outer covering 44 are at the same height along the direction of gravity g in the example (height difference 0 mm) or, in other words, lie in one plane.

[0038] The further cover profile 42 has a (walkable) tread section 45 and a height adjustment section 46 sloping towards the outer surface 44. In the example, the height adjustment section 46 has a first section 46', which borders the tread section 45, and a second section 46'', which borders the first section 46' (towards the outer surface 44). The first section 46' encloses a first angle α with the horizontal, and the second section 46'' can enclose a second angle β with the horizontal, wherein the second angle β is greater than the first angle α (cf. Fig.3 ).

[0039] In the example, the second section 46'' rests on the outer surface 44 at its end. The surface 45' of the tread section 45 (cf. Fig.3 ) of the further cover profile 42 and the surface 32' of the (first) cover profile 32 are at the same height in the example (cf. Fig.2 ). This allows them to form a tread surface.

[0040] The drainage profile 40 and the further cover profile 42 define between them a water drainage channel 50 which extends from an inlet 52 to an outlet 54.

[0041] In the example, the inlet 52 of the water drainage channel 50 is formed by the end 43 of the further cover profile 42 facing the cover profile 32 being spaced apart from the cover profile 32 and / or from a section 41 of the drainage profile 40 adjacent to the cover profile 32. In other words, a gap 56 is located between the end 43 of the further cover profile 42 facing the cover profile 32 and the cover profile 32 and / or the section 41 of the drainage profile 40 adjacent to the cover profile 32.

[0042] The outlet 54 of the water drainage channel 50 is formed by a drain section 58 of the further cover profile 42 which is open downwards in the direction of gravity g and which is arranged between the end of the drainage profile 40 facing away from the (first) cover profile and the outer covering 44.

[0043] On the wing underside 28, a further seal receptacle 60 is arranged, extending along or parallel to the longitudinal direction L, with, in the example, two seals 62, which extend at the inlet 52 with their free ends toward the first cover profile 32 or the deflection profile 40. The seals 62 are arranged in particular above the inlet 52 or on the side of the inlet 52 facing the (first) cover profile 32.

[0044] A weatherboard 64 is attached to the sash underside 28, which at least partially covers the additional cover profile 42 toward the outer side 16, at least the tread section 45 of the additional cover profile 42. In the example, the weatherboard 64 is attached to the sash underside 28. In the example, the additional seal receptacle 60 is connected to the weatherboard 64 using the same material.

[0045] In the example, the weather leg 64 has an additional sealing receptacle 66 extending along or parallel to the longitudinal direction L with a seal 68, which extends with its free ends to the further cover profile 42, in the example at the transition from the tread section 45 and height adjustment section 46.

[0046] The proposed design deliberately omits drop-down seals (door or window arrangement without drop-down seals). Regardless, all seals are designed as double-lipped lip seals.
