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, for example, from EP 1 312 743 B1. Such sliding doors can be manually operated via a handle provided on the respective leaf and a connecting rod fitting. Operation can be achieved by lowering the respective leaf in the fully closed state and first raising it for opening or sliding. During sliding, the leaf is guided by guide elements on a guide rail on the frame.

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

[0004] The invention is based on the object of increasing the burglar resistance of sliding door systems using simple structural means. It is desirable that the mounting of the leaf to the frame is not increased, or only increased to a negligible extent.

[0005] The sliding door assembly comprises a (stationary) frame and a (first) leaf (sliding leaf) that can be moved relative to the frame between an open position and a closed position along a sliding direction. The sliding door assembly also comprises another leaf element that is fixedly or displaceably arranged on or within the frame. The (first) leaf is arranged on the frame in front of the leaf element (the running side of the leaf relative to the leaf element), in particular running on the outside.

[0006] 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 guide element extends towards the guide rail or in the direction of the guide rail.

[0007] The sliding door assembly also includes a locking device 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 on the upper leaf cross member.

[0008] The locking parts are designed and / or arranged relative to one another in such a way that the locking parts overlap one another when the sash is in the closed position, wherein the first locking part engages behind the second locking part at least in sections on its side facing away from the sash element.

[0009] In other words, any unhinging movement of the sash transversely (laterally) to the sliding direction or orthogonally to the frame plane outwards (away from the sash element) is blocked by the overlapping locking elements. This prevents the sash from being unhinged in the closed position, even if the guide element is removed, for example, during a break-in attempt. The sash would then strike the first locking element, positioned in the guide rail, with the second locking element. The locking device thus represents an additional, redundant, but non-removable, burglar-resistant element, unlike the guide roller.

[0010] 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 device can always be used, for example with outward-running sashes, regardless of the width of the sash. Even when using the locking device, simple sash installation is possible, as the sash can be placed on a frame-side guide rail on the lower sash cross member (in the direction of gravity), pivoted in, and then held or guided relative to the frame by the guide elements. The locking components do not hinder sash installation, as they only overlap one another in or shortly before the sash is in the closed position relative to the frame.

[0011] The term "sliding door arrangements" includes not only sliding door arrangements but also sliding window arrangements.

[0012] The (stationary) frame of the sliding door arrangement can also be referred to as a fixed frame or blind frame.

[0013] The additional sash element can be a fixed panel or another sash that can be moved relative to the frame (sliding sash).

[0014] As already explained, the locking device comprises a first locking part and a second locking part. The locking device can be designed as a two-part locking device.

[0015] 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 and a raised position, for example, by means of a handle or a drive, and can be moved in the raised position (relative to the frame) between an open and a closed position.

[0016] The sliding door arrangement has an inside and an outside, or separates an inside (interior, e.g., of a building) from an outside (surroundings). As explained above, the (first) leaf is arranged on the frame in front of the leaf element, whereby the (first) leaf can be arranged to run inside or outside. Running inside means that the (first) leaf is arranged on the inside relative to the leaf element. Running outside means that the (first) leaf is arranged on the outside relative to the leaf element.

[0017] In both arrangements (inward-running and outward-running sash), the locking device 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 arrangement blocks or makes it more difficult to pry open the sash outwards, i.e., towards the outside of the sliding door arrangement or the building. With an inward-running sash, the locking arrangement blocks or makes it more difficult to pry open the sash inwards, i.e., towards the inside of the sliding door arrangement or the building.

[0018] 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 attached to the front side, or as a guide slider, preferably attached to the front side.

[0019] Preferably, the locking device is designed in such a way that it does not perform any guiding functions for the sash relative to the frame. The locking device serves exclusively as a burglar deterrent.

[0020] Advantageously, the second locking part can be arranged at the rear end of the sash or at the rear end of the sash cross member when the sash is moved into the closed position, so that the locking parts, when they overlap when the sash is in the closed position, are arranged at the rear end of the sash. Thus, the locking parts exert their burglar-deterrent effect 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.

[0021] Specifically, the guide element can be arranged at the rear end of the sash when the sash is moved into the closed position, with the second (sash-side) locking part being arranged adjacent to the guide element on the side of the guide element facing away from the rear sash end. In other words, the guide element is located, in particular directly, at the rear sash end, and the second locking part is located in front of the guide element when the sash is moved into the closed position, thus being offset from the front sash end. The second locking part can be arranged directly adjacent to the guide element, so that the guide element forms a contact surface or "stop" for the second locking part (the second locking part and the guide element touch each other). The guide element and / or the second locking part can be inserted into a fitting groove formed on the upper sash cross member.

[0022] In a preferred embodiment, the second locking part can have a protective bar that, when the sash is in the closed position, at least partially conceals the first locking part toward the rear end of the sash—when the sash is moved into the closed position. This further increases the burglar-deterrent effect, as the protective bar prevents a (burglar) tool from being pushed forward between the two locking parts.

[0023] Specifically, the protective bar can be formed integrally with the second locking part. This contributes to a stable design. It also facilitates simple production of the second locking part, for example, by investment casting, particularly stainless steel investment casting.

[0024] Advantageously, the second locking part can have a greater length along the sliding direction than the first locking part. This contributes to a reliable and sufficiently large overlap of the locking parts along the sliding direction when the sash is in the closed position.

[0025] The sash can be conveniently guided by means of roller carriages on a track attached to a lower frame cross member. The overlap of the locking parts in the closed position of the sash along the direction of gravity is greater 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 protection, as the locking device cannot simply be "bypassed" by lifting the sash.

[0026] Specifically, the locking parts can be designed such that the overlap of the locking parts in the closed position of the sash 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 parts.

[0027] In a preferred embodiment, a fitting groove extending along the upper sash cross member (in the direction of gravity) can be formed on the upper sash cross member, with the second locking part being inserted into the fitting groove, in particular inserted into the fitting groove and / or secured in the fitting groove. This contributes to a space-saving and stable attachment of the second locking part to the upper sash cross member.

[0028] Conveniently, the first locking part and / or the second locking part can each have a fastening section, with one or more fastening passages arranged in the fastening section, the central longitudinal axes of which (when installed on the sash and frame) are oriented along or parallel to the direction of gravity. In this way, the locking parts can be fastened using screws arranged in the fastening passages. This contributes to simple installation of the locking parts, as the locking parts can be easily screwed together.

[0029] In addition, burglary protection is improved because the screws cannot be reached from the outside when the sash is closed without damaging the sash and / or frame.

[0030] Specifically, the first locking part can comprise the fastening section, a connecting section, and an overlap section. The fastening section is arranged at the base (closed profile side) of the guide rail in the installed position. The overlap section forms a free end of the first locking part. The connecting section connects the fastening section to the overlap section. The fastening section can have a larger cross-section than the overlap section. The connecting section can preferably taper in its cross-section from the fastening section to the overlap section.

[0031] The second locking part can have the fastening section and an overlap section. In the installed position, the fastening section is arranged on the upper sash cross member or on the base (groove base) of a fitting groove formed on the upper sash cross member. The overlap section forms a free end of the second locking part. The fastening section can have a larger cross-section than the overlap section. In addition, the second locking part has the protective web described above, which extends from the fastening section. The protective web can be formed integrally with the overlap section, as if it were an extension of the overlap section. The overlap section and the protective web can form an L-shape in plan view.

[0032] 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 shows an embodiment of a sliding door arrangement with locking device in a schematic side view; Fig.2 shows the sliding door arrangement from Figure 1 in an enlarged and partially sectioned partial view, with the wing in the closed position and the locking parts and the guide element mounted; Fig.3 a view of the sliding door arrangement according to Figure 2 , wherein the guide element is dismantled; Fig.4 a partial sectional view of the sliding door arrangement from Figure 1 along a Figure 3 drawn section axis IV - IV; and Fig.5 the locking device of the sliding door arrangement from Figure 1 in a unique position in a perspective view.

[0033] Figure 1shows a sliding door arrangement, designated overall by reference numeral 10. The sliding door arrangement 10 has a stationary frame or 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, can be moved relative to the frame 12 along a displacement direction 14 between an open position and a closed position. The sash 16 can be raised or lowered by means of a drive (not shown), for example, manually by means of a handle or via a motor. The direction of gravity is designated by reference numeral g.

[0034] The frame 12 has a further sash element 18, which in the example is fixedly arranged within the frame 12 and is designed as a glazed fixed panel (marked with a diagonal cross in the drawing). The 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 field 30, e.g., a glazing 30. The sash frame 28 has an upper sash cross member 32, a lower sash cross member 34, and two vertical sash members 36, 38. In the example, the sash 16 is arranged on the frame 12 in front of the sash element 18, thus being 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 are arranged on the lower sash cross member 34, spaced apart along the sliding direction 14 and running in the guide rail 40.

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

[0038] The wing 16 is coupled at its upper wing cross member 32 to two guide elements 48 which are spaced apart from one another along the direction of displacement 14 and 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] In addition, 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 (cf. Fig.2 to 5). The first locking part 52 is arranged and secured in the guide rail 44. The second locking part 54 is arranged and secured on the upper sash cross member 32, specifically 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 one another in such a way that the locking parts 52, 54 overlap one another in the closed position of the wing 16, wherein the first locking part 52 engages behind the second locking part 54 on its side facing away from the wing element 18.

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

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

[0044] The second locking part 54 has a protective web 56 which, when the wing 16 is in the closed position, covers the first locking part 52 towards the rear end of the wing 16 - when the wing 16 is moved into the closed position (cf. Fig.2 and 3 ). In the example, the protective web 56 is formed integrally with the second locking part 54. In this case, the second locking part 54 has a greater length L 2 along the displacement direction 14 than the first locking part 52 with its length L 1 .

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

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

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

[0048] The first locking part 52 has the fastening section 52', a connecting section 52'' and an overlap section 52‴ (cf. Fig.4 and 5). The fastening section 52' is arranged in the 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 part 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 its cross-section in braced sections 60 from the fastening section 52' to the overlap section 52‴.

[0049] The second locking part 54 has the fastening section 54' and an overlap section 54". The fastening section 54' is arranged in the installed position on the upper sash cross member 32 or on the base (groove base) of the fitting groove 33. The overlap section 54'' forms a free end of the second locking part 54. In the example, the fastening section 54' has a larger cross-section than the overlap section 54''. In addition, the second locking part 54 has the protective web 56 described above, which extends from the fastening section 54'. In the example, the protective web 56 is formed integrally with the overlap section 54'', as an extension of the overlap section 54'', so to speak. The overlap section 54'' and the protective web 56 form an L-shape in plan view.

[0050] As in Figure 3As shown, the locking device 50 provides burglary protection even when the guide element 48 has been removed. Thus, the two locking parts 52, 54 overlap. The screws arranged in fastening passages 58, 60 are inaccessible to a burglar. The protective web 56 prevents a burglar's tool from being pushed between the locking parts 52, 54.

[0051] In the example, the sliding door assembly 10 and the locking device 50 were arranged on a leaf 16 running outward on the frame 12 in front of the leaf element 18. The locking device 50 blocks or makes it difficult to pry open the leaf 16 outward, i.e., toward the outside of the sliding door assembly 10 or the building.

[0052] As explained above, the locking device 50 can also be used in a sliding door arrangement 10 with a leaf 16 running inward on the frame 12 in front of the leaf element 18. The locking device 50 blocks or makes it difficult to pry open the leaf 16 inward, i.e., toward the inside of the sliding door arrangement 10 or the building.
