Description

[0001] The invention relates to a door or window arrangement with the features of the preamble of claim 1. Furthermore, the invention relates to a building enclosure with the features of the dependent claim.

[0002] Door or window arrangements of the type mentioned above, with, for example, a sash opening outwards relative to the frame, are known from the prior art. See DE 10 2013 110 832 A1. A relevant door or window arrangement is also known from DE 20 2017 106040 U1. Such door or window arrangements have a step on the frame side of the lower frame mullion, against which the sash can seal tightly in the closed position with a sash overlap formed on the underside of the sash. Since the sash typically has lateral sash overlaps on the sides as well as a sash overlap formed on the top of the sash, with which the sash can seal tightly against the frame in the closed position, a continuous seal of the sash against the frame is achieved (continuous sealing plane). However, the threshold poses a tripping hazard or an obstacle, especially for people with physical disabilities such as...Wheelchair users or seniors with walkers.

[0003] The invention aims to provide an improved door or window arrangement. It is desirable to improve accessibility and to ensure sufficient airtightness in a cost-effective manner.

[0004] The invention solves this problem by means of a door or window arrangement with the features of claim 1.

[0005] The door or window arrangement 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 (possibly an outward-opening sash or outward-opening door).

[0006] The sash features lateral overlaps, each with an attached overlap seal for sealing against the frame or vertical frame members (when the sash is closed). Optionally, the sash can also have an overlap on its upper surface with an attached overlap seal for sealing against the frame or an upper frame member. The lower surface of the sash, however, is designed without overlaps (no overlap on the underside of the sash).

[0007] The frame has a lower frame cross member extending along a longitudinal direction, with a sill having a sill surface, in particular a tread surface, arranged on the lower frame cross member towards the outside.

[0008] At the lower end of the sash, a weather bar extending along a specific direction is arranged on the outer side, incorporating an elastic seal (also extending along this direction). When the sash is closed, the seal's direction of extension is oriented along or parallel to the longitudinal axis. The seal projects downwards from the weather bar (along the direction of gravity) so that, when the sash is closed, it forms a seal against the sill surface.

[0009] An end cap is attached to one or both ends of the weather bar. Each end cap has a downward-projecting section (along the direction of gravity) with a sill contact surface, by means of which the downward-projecting section seals against the sill surface when the sash is closed.

[0010] Each end cap has a lateral section that overlaps the corresponding lateral sash overlap (sideways) and seals against the lateral sash overlap and its overlap seal. Optionally, the lateral section may have a through-hole for fastening it to the lateral sash overlap with a screw. The through-hole may be chamfered or countersunk on the outside of the lateral section (weather side) to allow for sealing with the screw head, particularly a countersunk head.

[0011] A receptacle is formed on or in the end cap, in particular in a base section of the end cap, which has a cross-section complementary to the sealing of the weather bar and seals an end section of the seal.

[0012] The proposed design improves accessibility, particularly for outward-opening sashes (outward-opening doors), as it eliminates the need for a sash overlap on the bottom and a corresponding stop that rises from the floor. The end cap attached to the front of the weather bar creates a tight seal at the key interfaces for sealing: the threshold surface, the overlap seal on the side sash overlap, and the elastic seal in the weather bar when the sash is closed. This ensures a sufficient seal on the underside of the sash. With side sash overlaps and a top sash overlap, each with its own overlap seal, a continuous sealing plane between the sash and frame can be achieved.

[0013] Specifically, the end cap can have a base section, particularly one that is essentially cuboid, in which the receptacle for the seal is formed and / or from which the lateral section of the end cap extends. This contributes to a comparatively stable design of the end cap, as the various sections of the end cap are connected by means of the base section.

[0014] In a preferred embodiment, a fastening section can extend from the base section, by means of which the end cap is attached to the (relevant) end face of the weather bar, preferably by means of a screw. This contributes to a stable attachment of the end cap to the weather bar. The fastening section has a passage for a screw (fastening screw) to secure the fastening section to the weather bar. The passage can be chamfered or countersunk on the outside of the fastening section (weather side) to seal against the screw head, in particular a countersunk head.

[0015] On the inside of the fastening section (non-weather side), a groove is formed for the sealing reception of an end section of the weather bar. The fastening section extends, in particular, transversely to the aforementioned direction of extension from the base section of the end cap.

[0016] Advantageously, a coupling section can extend from the base section along or parallel to the direction of extension, penetrating a corresponding pocket on the weather bar, the pocket being formed on a web of the weather bar that engages the underside of the wing. This stabilizes the coupling between the end cap and the weather bar and contributes to a good seal. Independently of the pocket described here, a groove extending along or parallel to the direction of extension can be formed on the web of the weather bar that engages the wing, for securing the weather bar seal.

[0017] Advantageously, the base section can have a contact surface on its upper surface (oriented upwards along the direction of gravity) by means of which the base section contacts the wing on its underside, or, in other words, is in contact with the underside of the wing. This achieves improved sealing and increased stability between the end cap and the wing.

[0018] In a preferred embodiment, the threshold can have a slope towards the outside, with the threshold contact surface of the downward-projecting section of the end cap being adapted to the slope of the threshold. In other words, the threshold contact surface is adapted to the slope of the threshold in such a way that, when the sash is closed, the threshold contact surface rests uniformly and tightly on the threshold surface. The outward slope of the threshold compensates for a height difference between a floor covering on the outside and the lower frame cross member or the highest point of the lower frame cross member. This improves accessibility. Furthermore, it provides a direction of water runoff should water reach the threshold surface.Specifically, the sill contact surface of the downward-projecting section and the sill surface of the sill can be oriented parallel to each other when the wing is in the closed position.

[0019] Advantageously, the threshold can be designed separately from the lower frame cross member and be in contact with and / or connected to it. In the simplest case (contact), the threshold can be positioned directly next to the frame cross member and be in contact with it, i.e., abutting it. This simplifies installation, as the threshold can be subsequently mounted to the lower frame cross member, for example, after the installation of flooring on the exterior. Furthermore, repairs are easier, since only the threshold, and not the entire lower frame cross member, needs to be replaced. Adaptation to the surroundings of the door or window arrangement is also possible, for example, by using thresholds of varying widths (the width here refers to the extent of the threshold in the direction of passage through the door or window). A connection of the threshold to the lower frame cross member, e.g.,A screw connection or a plug connection contributes to a stable coupling of the components.

[0020] Advantageously, the seal can be spaced at one or both of its end faces from the overlap seal of the relevant side wing overlap, with a section of the end cap, in particular the base section of the end cap, being arranged within this space. The seal deliberately terminates at one or both end faces with a gap to the relevant overlap seal, thereby creating space for a section of the end cap. Thus, the end cap can connect the various interfaces and perform its sealing function.

[0021] Specifically, the end cap can be made in one piece and / or from elastic soft plastic. This contributes to a stable design and a sufficiently good sealing effect.

[0022] The aforementioned task is also solved by a building enclosure with the characteristics of the subordinate claim.

[0023] The building enclosure is designed and / or intended to separate the interior of a building from its surroundings (exterior or building exterior). The building enclosure includes a door or window arrangement with one or more of the aspects described above. Furthermore, the building enclosure has an interior floor covering (interior floor covering) adjacent to the lower frame cross member and an exterior floor covering (exterior floor covering) adjacent to the lower frame cross member and the sill. The height difference (h) along the direction of gravity between the highest point of the sill and the lower frame cross member, relative to the interior and exterior floor coverings, is more than 0 mm and a maximum of 20 mm (0 < h ≤ 20 mm), preferably more than 5 mm and a maximum of 15 mm (5 < h ≤ 15 mm).

[0024] Regarding the advantages achievable with the building enclosure, reference is made to the relevant explanations concerning door or window arrangement. The measures described in connection with the door or window arrangement and / or those described below can be used for further design of the building enclosure.

[0025] The invention is explained in more detail below with reference to the figures, where identical or functionally identical elements are provided with identical reference numerals, possibly only once. The figures show: Fig. 1 shows a section of an embodiment of the door or window arrangement with a view of an end face of the weather bar and the end cap in a perspective view; Fig. 2 shows the section of the door or window arrangement made of Figur 1 with end cap removed; Fig. 3 the door or window arrangement along a in Figur 1 section axis III-III shown; and Fig. 4a-c the end cap of the door or window assembly in several views.

[0026] Figur 1 Figure 1 shows a section of a building enclosure, which is designated in its entirety by the reference symbol 100. The building enclosure 100 is designed and intended to separate an interior building surface 102 from the exterior or surroundings 104 (building exterior).

[0027] The building termination 100 has a door or window arrangement 10, which in turn has a lower frame cross member 26 with a sill 28 arranged on it and which is described in more detail below.

[0028] Furthermore, the building termination 100 has an inner covering 106 adjacent to the lower frame cross member 26 and an outer covering 108 adjacent to the lower frame cross member 26 and the sill 28. The height difference h along the direction of gravity g between the highest point of the sill 28 and the lower frame cross member 26 relative to the inner covering 106 and the outer covering 108 is more than 0 mm and a maximum of 20 mm (0 < h ≤ 20 mm; cf. Fig.3 ). In the example, the inner covering 106 is arranged higher than the outer covering 108, contrary to the direction of gravity g.

[0029] The door or window arrangement 10 has a frame 12 (only partially shown) and a sash 16 mounted on the frame 12 and pivotable relative to the frame 12 towards the outside 104 between an open position and a closed position (outward opening sash 16; only partially shown).

[0030] The sash 16 has lateral sash overlaps 18 (only one sash overlap is shown here), to which an overlap seal 20 is attached for sealing with the frame 12 or a vertical frame member 22 (in the closed position of the sash 16) (see figure). Fig.1 Optionally, the sash 16 can also have a sash overlap on its upper side with an attached overlap seal for sealing against the frame 12 (not shown). On its underside 24, however, the sash 16 is designed without an overlap (no sash overlap on the underside 24 of the sash 16; see Figure 1). Fig.3 ).

[0031] The frame 12 has a lower frame cross member 26 extending along a longitudinal direction L, wherein a sill 28 with a sill surface 29, in particular a tread surface, is arranged on the lower frame cross member 26 towards the outside 104 (cf. Fig.1 ).

[0032] In the example, the lower frame cross member 26 has a base profile 30, e.g. made of plastic, two top profiles 31, 32 and a tread profile 33 (see Fig.3 The top profiles 31, 32 and the tread profile 33 can each be made of, for example, aluminum. In this example, the tread profile 33 is flush with the interior covering 106, meaning that the surfaces of the tread profile 33 and the interior covering 106 are at the same height.

[0033] At the lower end of the wing 16, towards the outside 14, a weather bar 36 extending along a direction of extension E with an elastic seal 38 (also extending along the direction of extension E) is arranged (cf. Fig.1-3 The direction of extension E is oriented along or parallel to the longitudinal direction L when the sash 16 is closed. The seal 38 projects downwards from the weather bar 36 along the direction of gravity g in such a way that it rests sealingly on the sill surface 29 when the sash 16 is closed (cf. Fig.3 ).

[0034] An end cap 40 is attached to one or both end faces 39 of the weather bar 36 (in the example only the end face is shown) (cf. Fig.1 The end cap 40 has a downwardly projecting section 41 (along the direction of gravity g) with a threshold contact surface 42, by means of which the downwardly projecting section 41 rests sealingly on the threshold surface 29 in the closed position of the wing 16 (cf. Fig.1 , 3 and 4cThe end cap 40 has a lateral section 43 by means of which the end cap 40 overlaps the associated lateral wing overlap 18 (laterally) and seals against the lateral wing overlap 18 and its overlap seal 20 (see Fig.1 and 4b ).

[0035] In the lateral section 43, a through hole 43' is formed for fastening the lateral section 43 to the lateral wing overlap 18 by means of a screw (see figure). Fig.1 and 4a ). In the example, the through hole 43' has a chamfered or countersunk edge on the outside of the lateral section 43 (weather side) for sealing with the screw head, in particular a countersunk head.

[0036] A receptacle 45 is formed on or in the end cap 40, in particular in a base section 44 of the end cap 40, which has a cross-section complementary to the seal 38 of the weather bar 36 and seals an end section of the seal 38 (cf. Fig.3 and 4b ). In the example, image 45 has a T-shaped cross-section.

[0037] As already indicated, the end cap 40 has a (essentially cuboid) base section 44 in which the receptacle 45 is formed and from which, in the example, the lateral section 43 extends (cf. Fig.4b ).

[0038] A fastening section 46 extends from the base section 44, by means of which the end cap 40 is attached to the relevant end face of the weather bar 36, in the example by means of a screw 60 (see figure). Fig.1 and 5a). In the fastening section 46, a passage 47 is formed for the screw 60 for fastening the fastening section 46 to the weather bar 36. The passage 47 is chamfered or countersunk on the outside 46' of the fastening section 46 (weather side) for sealing with the screw head, in particular a countersunk head.

[0039] On the inner side 46'' of the fastening section 46 (non-weather side), a groove 48 is formed for the sealing reception of an end section of the weather bar 36. The fastening section 47 extends, in particular, transversely to the aforementioned direction of extension E away from the base section 46 of the end cap (see figure). Fig.4b ).

[0040] From the base section 44, a coupling section 49 extends along or parallel to the direction of extension E, which penetrates into a corresponding pocket 61 on the weather bar 36, the pocket 61 being formed on a web 62 of the weather bar 36 which engages the wing 16 on its underside 24 (cf. Fig.3 ). Regardless of this, a screw receptacle 64 for receiving a screw shaft (screw-in section) of the screw 60 is also provided on the weather bar 36.

[0041] The base section 44 has a contact surface 50 on its upper surface (oriented upwards along the direction of gravity g), by means of which the base section 44 contacts the wing 16 on its underside 24 (cf. Fig.4b ).

[0042] The threshold 28 has a slope towards the outside 14, whereby the threshold contact surface 42 of the downwardly projecting section 41 of the end cap 40 is adapted to the slope of the threshold 28 (cf. Fig.1 , 3 and 4b The threshold contact surface 42 is thus adapted to the slope of the threshold 28 in such a way that, when the sash 16 is closed, the threshold contact surface 42 rests uniformly and sealingly on the threshold surface 29. The threshold contact surface 42 of the downwardly projecting section 41 and the threshold surface 29 of the threshold 28 can be oriented parallel to each other when the sash 16 is closed.

[0043] In this example, the threshold 28 is formed separately from the lower frame cross member 26 and connected to the frame cross member 26, in this case by plugging it in (see figure). Fig.3 ).

[0044] The seal 38 is spaced at one or both of its end faces from the overlap seal 20 of the relevant lateral wing overlap 18, with a section of the end cap 40 being arranged in this space, in particular the base section 44 of the end cap 40. The seal 38 deliberately terminates at one or both end faces with a space from the relevant overlap seal 20, thereby creating space for a section of the end cap 40.

[0045] The end cap 40 in the example is made in one piece and is made of elastic soft plastic.

[0046] In summary, the invention provides for replacing the existing tripping hazard (step) on a sash, preferably one that opens outwards, with a barrier-free threshold. For this purpose, a threshold with an outward slope is provided, creating a slight offset (e.g., 5 mm) between the exterior surface and the threshold surface or the interior floor, thereby reducing the barrier effect.

[0047] In order to maintain the horizontal gap at the bottom of the sash (distance between the threshold and the sash rebate, e.g., 10 mm) for existing hardware and other accessories, the sash overlap on the underside of the sash is omitted or milled off, and a weather bar with a lower profile is attached to the outside at the bottom of the sash, in which an elastic seal is also installed.

[0048] The weather bar with its elastic seal is designed so that the elastic seal can run up to the slope of the threshold when the wing is closed or when the door is closed, and seals horizontally across the width of the wing against the threshold.

[0049] At the end faces of the elastic seal, there is a gap between it and the lateral overlap seals of the sash. An end cap according to the invention, preferably made of an elastic soft plastic, which is attached to the end face of the weatherstrip, therefore serves to seal the interfaces: Threshold surface (slope in the exterior area), overlap seal on the side sash overlap and elastic seal in the weather bar to connect them sealingly in the closed position of the sash and consequently contribute to a continuous sealing plane between the sash and the frame.
