SLIDING DOOR ARRANGEMENT

Description

[0001] The invention relates to a sliding door arrangement having the features of the preamble of claim 1.

[0002] Sliding door arrangements of the type mentioned above are known from the prior art, e.g., from EP 1 312 743 B1. Such sliding doors can be operated manually via a handle provided on each leaf and a drive rod fitting. Operation can be achieved by lowering the respective leaf in the fully closed position and then lifting it to open or slide. During sliding, the leaf is guided by guide elements along a guide rail on the frame.

[0003] Furthermore, guide elements and a guide rail are known from the prior art, which the applicant presented as a guide system designated GU P2301 at the BAU 2023 trade fair. In this guide system, the guide rail is mounted on the frame, and the guide elements are mounted on the end face of the sash and guided in the guide rail. However, if, in the case of a sash, e.g., an outward-sliding sash, the guide element located at the rear in the closing direction of the sash is removed during a break-in attempt, there is a risk that the sash can be pried open at this point.

[0004] Sliding door arrangements with anti-lift devices are disclosed in GB 2 453 954 A, EP 2 476 829 A2 and DE 10 2016 216835 A1.

[0005] The invention is based on the objective of increasing the burglary resistance of sliding door arrangements using simple design means. It is desirable that the mounting of the door leaf to the frame is either not increased at all or only to a negligible extent.

[0006] The sliding door assembly comprises a (stationary) frame and a (first) sash (sliding sash) that can be moved along a sliding direction relative to the frame between an open position and a closed position. The sliding door assembly also includes a further sash element that is fixed or slidably arranged on or within the frame. The (first) sash is positioned on the frame in front of the sash element (running side of the sash relative to the sash element), in particular running on the outside.

[0007] A guide rail is attached to an upper frame cross member of the frame (in the direction of gravity), and at least one guide element is attached to an upper wing cross member of the wing (in the direction of gravity), which extends towards the guide rail or in the direction of the guide rail.

[0008] Furthermore, the sliding door assembly features a locking mechanism with a first locking part and a second locking part. The first locking part is arranged and secured in the guide rail, and the second locking part is arranged and secured to the upper cross member of the door leaf.

[0009] The locking bolts are designed and / or arranged relative to each other in such a way that the locking bolts overlap each other when the sash is closed, with the first locking bolt engaging behind the second locking bolt at least partially on its side facing away from the sash element.

[0010] In other words, the overlapping locking bolts prevent the sash from being lifted outwards (laterally) to the direction of movement or perpendicular to the frame plane (away from the sash). Therefore, even if the guide element is removed, for example during a break-in attempt, the sash cannot be lifted out of the closed position. The second locking bolt would then collide with the first locking bolt, which is positioned in the guide rail. The locking mechanism thus represents an additional, redundant, but unlike the guide roller, non-removable burglar-resistant element.

[0011] The proposed design also has the advantage that no additional guide rail is required. Furthermore, the locking components are comparatively small and inexpensive to manufacture. The locking mechanism can always be used, for example, with outward-opening sashes, regardless of the sash width. Even when using the locking mechanism, simple sash installation is possible, as the sash is placed on a frame-side track on the lower (in the direction of gravity) sash cross member, pivoted into position, and then held and guided relative to the frame by the guide elements. The locking components do not obstruct sash installation, as they only overlap each other when the sash is in or just before it is closed relative to the frame.

[0012] The term "sliding door arrangements" includes not only sliding door arrangements but also sliding window arrangements.

[0013] The (stationary) frame of the sliding door arrangement can also be referred to as a fixed frame or frame.

[0014] The additional wing element can be a fixed panel or another wing that can be moved relative to the frame (sliding wing).

[0015] As already explained, the locking mechanism has a first locking part and a second locking part. The locking mechanism can be designed as a two-part locking device.

[0016] The (first) sash can be designed as a sliding sash or as a lift-and-slide sash. The lift-and-slide sash can be moved relative to the frame between a lowered position and a raised position, for example by means of a handle or a drive mechanism, and in the raised position it can be moved (relative to the frame) between an open position and a closed position.

[0017] The sliding door assembly has an inside and an outside, or rather, it separates an inside (interior, e.g., of a building) from an outside (environment). As described above, the (first) leaf is positioned on the frame in front of the sash element, and the (first) leaf can be arranged as an inward-running or outward-running leaf. Inward-running means that the (first) leaf is located on the inside relative to the sash element. Outward-running means that the (first) leaf is located on the outside relative to the sash element.

[0018] In both configurations (inward-running and outward-running sash), the locking mechanism contributes to increased burglary protection, as it makes it more difficult to pry open the sash, for example, if the rear guide element in the closing direction of the sash is damaged or removed during a break-in attempt. With an outward-running sash, the locking mechanism blocks or hinders prying the sash outwards, i.e., towards the outside of the sliding door assembly or the building. With an inward-running sash, the locking mechanism blocks or hinders prying the sash inwards, i.e., towards the inside of the sliding door assembly or the building.

[0019] The guide rail can be arranged in a groove formed in the upper frame cross member. The at least one guide element can be designed as a guide roller, preferably mounted at the end face, or as a guide slide, preferably mounted at the end face.

[0020] Preferably, the locking mechanism is designed such that it does not guide the sash relative to the frame. The locking mechanism serves solely as a burglar deterrent.

[0021] Advantageously, the second locking bolt can be positioned at the rear end of the sash (when the sash is moved into the closed position) or at the rear end of the sash cross member, so that when the locking bolts overlap in the closed position, they are located at the rear end of the sash. Thus, the locking bolts exert their burglar-resistant effect precisely where a burglar would attempt to pry open the sash, namely at the rear end of the sash in the closing direction. This contributes to increased burglar resistance.

[0022] Specifically, the guide element can be located at the rear end of the sash when the sash is moved into the closed position, with the second (sash-side) locking bolt part being located adjacent to the guide element on the side of the guide element facing away from the rear end of the sash. In other words, the guide element is located, particularly directly, at the rear end of the sash, and the second locking bolt part is located in front of the guide element when the sash is moved into the closed position, i.e., offset towards the front end of the sash. The second locking bolt part can be located directly adjacent to the guide element, so that the guide element forms a contact surface or a "stop" for the second locking bolt part (the second locking bolt part and the guide element are in contact with each other). The guide element and / or the second locking bolt part can be inserted into a hardware groove formed on the upper sash mullion.

[0023] In a preferred embodiment, the second locking bolt can have a protective rib which, when the sash is in the closed position, at least partially conceals the first locking bolt towards the rear end of the sash (when the sash is moved into the closed position). This further increases the burglar-resistant effect, as the protective rib prevents a (burglar) tool from being inserted between the two locking bolts.

[0024] Specifically, the protective bar can be formed integrally with the second locking bolt. This contributes to a stable design. Furthermore, this facilitates the simple manufacture of the second locking bolt, for example, by investment casting, particularly stainless steel investment casting.

[0025] Advantageously, the second locking bolt section can have a greater length along the direction of movement than the first locking bolt section. This contributes to a reliable and sufficiently large overlap of the locking bolt sections along the direction of movement when the sash is in the closed position.

[0026] The sash can be advantageously guided on a track attached to a lower frame crossmember by means of carriages equipped with rollers, whereby the overlap of the locking components in the closed position of the sash is greater along the direction of gravity than the height difference required to lift the carriages out of the track (measurement along the direction of gravity between a lower edge of the rollers and a top edge of the track). This contributes to increased burglary resistance, as the locking mechanism cannot simply be bypassed by lifting the sash.

[0027] Specifically, the locking bolt components can be designed such that the overlap of the locking bolt components in the closed position along the direction of gravity is at least 5 mm (millimeters), preferably at least 7 mm. This contributes to a sufficiently high burglar-resistant effect of the locking bolt components.

[0028] In a preferred embodiment, a fitting groove extending along the upper sash cross member (in the direction of gravity) can be formed, wherein the second locking bolt part is inserted into the fitting groove, in particular inserted into the fitting groove and / or fastened in the fitting groove. This contributes to a space-saving and stable fastening of the second locking bolt part to the upper sash cross member.

[0029] Advantageously, the first and / or second locking bolt section can each have a fastening section, with one or more fastening holes arranged within each fastening section. The central longitudinal axes of these holes (when installed on the sash and frame) are oriented along or parallel to the direction of gravity. In this way, the locking bolt sections can be fastened by means of screws located in the fastening holes. This facilitates easy installation of the locking bolt sections, as they can be easily screwed in place. Furthermore, burglary resistance is improved because the screws are inaccessible from the outside when the sash is closed, without damaging the sash and / or frame.

[0030] Specifically, the first locking section can comprise a fastening section, a connecting section, and an overlapping section. The fastening section is positioned at the base (closed profile side) of the guide rail when installed. The overlapping section forms a free end of the first locking section. The connecting section joins the fastening section to the overlapping section. The fastening section can have a larger cross-section than the overlapping section. The connecting section preferably tapers in cross-section from the fastening section to the overlapping section.

[0031] The second locking bolt section can include a fastening section and an overlap section. In its installed position, the fastening section is located on the upper sash mullion or at the base (groove base) of a hardware groove formed on the upper sash mullion. The overlap section forms a free end of the second locking bolt section. The fastening section can have a larger cross-section than the overlap section. Furthermore, the second locking bolt section has the protective web described above, which extends from the fastening section. The protective web can be formed integrally with the overlap section, essentially as an extension of the overlap section. In plan view, the overlap section and the protective web can form an L-shape.

[0032] 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 an embodiment of a sliding door arrangement with a locking device in a schematic side view; Fig. 2 shows the sliding door arrangement made of Figure 1 in an enlarged and partially cutaway view, with the sash in the closed position and the locking parts and the guide element mounted; Fig. 3 a view of the sliding door arrangement accordingly Figure 2 , with the guide element removed; Fig. 4 a partial sectional view of the sliding door assembly made of Figure 1 along a Figure 3 section axis IV - IV shown; and Fig. 5 the locking mechanism of the sliding door assembly made of Figure 1 in isolation in a perspective view.

[0033] Figure 1Figure 10 shows a sliding door arrangement, designated as a whole by reference numeral 10. The sliding door arrangement 10 comprises a fixed frame 12 and a sash 16 of a window or door that can be raised relative to the frame 12 and, in the raised position, moved along a displacement direction 14 relative to the frame 12 between an open position and a closed position. The raising and lowering of the sash 16 can be effected by means of a drive mechanism (not shown), e.g., manually via a handle or by a motor. The direction of gravity is designated by reference numeral g.

[0034] Frame 12 has a further sash element 18, which in this example is fixedly arranged within frame 12 and is designed here as a glazed fixed panel (marked with a diagonal cross in the drawing). Frame 12 has a lower frame cross member 20, an upper frame cross member 22, and two vertical frame members 24, 26.

[0035] The sash 16 has a sash frame 28 that defines a sash area 30, e.g., a glazed panel 30. The sash frame 28 has an upper sash cross member 32, a lower sash cross member 34, and two vertical sash mullions 36, 38. In this example, the sash 16 is arranged on the outside of the frame 12 in front of the sash element 18, and is therefore located on the outside of the sliding door assembly 10 with respect to the sash element 18.

[0036] A guide rail 40 is arranged on the lower frame cross member 20. Two carriages 42, spaced apart from each other along the direction of movement 14, are arranged on the lower wing cross member 34 and run in the guide rail 40.

[0037] A guide rail 44 is arranged in a groove 43 on the upper frame cross member 22 (see figure). Fig.2 to 4In the example, the guide rail 44 has an essentially U-shaped cross-section with a base section 45 and two side sections 46 projecting orthogonally from it (cf. Fig.4 ).

[0038] The wing 16 is coupled at its upper wing cross member 32 to two guide elements 48 spaced apart from each other along the direction of displacement 14, which extend to the guide rail 44 and by means of which the wing 16 is guided in the guide rail 44 (cf. Fig.1 The guide elements 48 can each be designed as sliding elements.

[0039] Furthermore, the sliding door arrangement 10 has a locking device 50, which is described in more detail below.

[0040] The control device 50 has a first locking part 52 and a second locking part 54 (see Fig.2 to 5The first locking element 52 is arranged and fastened in the guide rail 44. The second locking element 54 is arranged and fastened on the upper sash cross member 32 in a fitting groove 33 extending along the sash cross member 32.

[0041] The locking parts 52, 54 are designed and / or arranged relative to each other such that the locking parts 52, 54 overlap each other when the sash 16 is in the closed position, with the first locking part 52 engaging behind the second locking part 54 on its side facing away from the sash element 18.

[0042] The second locking part 54 is arranged at the rear end of the sash 16 when the sash 16 is moved into the closed position, so that the locking parts 52, 54 are arranged at the rear end of the sash 16 when they overlap in the closed position of the sash 16 (cf. Fig.2 and 3 ).

[0043] The guide element 48 is arranged at the rear end of the sash 16 when the sash 16 is moved into the closed position, with the second locking part 54 being arranged adjacent to the guide element 48 on the side of the guide element 48 facing away from the rear end of the sash (see Fig.2 In this example, the guide element 48 is located at the rear end of the sash, and the second locking bolt 54 is positioned in front of the guide element 48 when the sash 16 is moved into the closed position, thus offset towards the front end of the sash. The guide element 48 forms a contact surface or a "stop" for the second locking bolt (simple installation). The guide element 48 and the second locking bolt 54 are inserted into the hardware groove 33.

[0044] The second locking bolt part 54 has a protective web 56 which, when the sash 16 is in the closed position, covers the first locking bolt part 52 towards the rear end of the sash 16 when the sash 16 is moved into the closed position (see figure). Fig.2 and 3 In the example, the protective web 56 is formed integrally with the second locking element 54. The second locking element 54 has a greater length L2 along the displacement direction 14 than the first locking element 52 with its length L1.

[0045] As explained above, the sash 16 is guided on the track 40, which is attached to the lower frame cross member 20, by means of carriages 42 equipped with rollers. When the sash 16 is closed, the overlap of the locking elements 52, 54 along the direction of gravity g is greater than the height difference required to lift the carriages 42 out of the track 40 (not shown).

[0046] The locking bolts 52, 54 are designed such that the overlap U of the locking bolts 52, 54 in the closed position of the sash 16 along the direction of gravity g is at least 7 mm (millimeters) (cf. Fig.4 ).

[0047] The first locking bolt part 52 and the second locking bolt part 54 each have a fastening section 52', 54', wherein in the fastening section 52', 54' one or more fastening passages 58, 60 are arranged, the central longitudinal axes of which, in the installed position on the sash 16 or frame 12, are oriented along the direction of gravity g (cf. Fig.3 ).

[0048] The first locking section 52 has the fastening section 52', a connecting section 52'' and an overlapping section 52''''" (see Fig.4 and 5The fastening section 52' is arranged in its installed position at the base (closed profile side or base section 45) of the guide rail 44. The overlap section 52‴ forms a free end of the first locking section 52. The connecting section 52'' connects the fastening section 52' to the overlap section 52'''. The fastening section 52' can have a larger cross-section than the overlap section 52'''. In the example, the connecting section 52'' tapers in cross-section from the fastening section 52' to the overlap section 52‴ in braced sections 60.

[0049] The second locking bolt section 54 has a fastening section 54' and an overlap section 54''. In its installed position, the fastening section 54' is located on the upper sash transom 32 or at the base (groove base) of the hardware groove 33. The overlap section 54'' forms a free end of the second locking bolt section 54. In this example, the fastening section 54' has a larger cross-section than the overlap section 54''. Furthermore, the second locking bolt section 54 has the protective web 56 described above, which extends from the fastening section 54'. In this example, the protective web 56 is formed integrally with the overlap section 54'', essentially as an extension of the overlap section 54''. In plan view, the overlap section 54'' and the protective web 56 form an L-shape.

[0050] As in Figure 3As shown, the locking mechanism 50 also provides burglary protection even if the guide element 48 has been removed. In this case, the two locking parts 52, 54 are in overlapping position. The screws located in the fastening channels 58, 60 are inaccessible to a burglar. The protective bar 56 prevents a burglary tool from being inserted between the locking parts 52, 54.

[0051] In this example, the sliding door assembly 10 and the locking device 50 were arranged on a sash 16 that runs on the outside of the frame 12 in front of the sash element 18. The locking device 50 blocks or hinders the sash 16 from being pried open outwards, i.e., towards the outside of the sliding door assembly 10 or the building.

[0052] As explained above, the locking device 50 can also be used with a sliding door assembly 10 with a sash 16 running inwards on the frame 12 in front of the sash element 18. The locking device 50 blocks or hinders the sash 16 from being pried open inwards, i.e., towards the inside of the sliding door assembly 10 or the building.
