Description

[0001] The invention relates to a sliding door arrangement with a fixed frame and a sliding sash movable relative thereto according to the preamble of claim 1. Furthermore, the invention relates to a method for assembling a sliding door arrangement according to the dependent claim.

[0002] Sliding door arrangements and sliding leaves of the type mentioned above are known from the prior art, for example from US 2022 / 154521 A1. The mass of such leaves can sometimes be 400 kg (kilograms) or more, depending on the leaf size. Such sliding leaves are usually guided on the fixed frame in two ways: firstly, by means of roller-enclosing running shoes on a lower frame cross member or on the floor, and secondly, by means of a corresponding guide element in a guide rail that is attached to an upper frame cross member of the fixed frame.

[0003] For installation in a fixed frame, such a sash must first be connected to the guide on the upper frame cross member and to the guide rail there. Then, it can be placed freely and tilted downwards onto the track using the carriages (first inserted into the guide rail at the top, then placed onto the track at the bottom). This is particularly complex and cumbersome with heavy sashes. For example, due to space constraints, the locking mechanism must be installed before the sash is even inserted. This not only complicates installation but also makes subsequent disassembly, for example for maintenance or repair, correspondingly difficult and time-consuming. Due to the complex handling and the heavy sashes, installers face a significant risk of injury during both installation and removal.

[0004] The invention is based on the objective of enabling simple and safe assembly of a sliding door arrangement.

[0005] The sliding door arrangement has a fixed frame and a sliding sash that can be moved relative to the fixed frame between at least one open position and one closed position along a sliding direction.

[0006] Furthermore, the sliding door assembly features a locking device for locking the sliding sash to an upper frame cross member of the fixed frame (relative to the direction of gravity g). The locking device, in turn, has a locking bar guided on the sliding sash with a locking head (which can be coupled to or is coupled with the locking bar) facing the upper frame cross member. The locking device can be configured predominantly on the sash side or entirely on the sash side.

[0007] The sliding door assembly also includes a guide device for guiding the sliding panel in a guide rail attached to the upper frame cross member. The guide device can engage the guide rail with a guide section (e.g., a U-shaped, downward-opening cross-section). When attached to the sliding panel, the guide device can guide the sliding panel along the upper frame cross member (guide rail).

[0008] The bolt head has a lower head piece and an upper head piece. The head pieces, in turn, have corresponding profile features (connection contour) by means of which the head pieces can be positively connected to each other in such a way that (in the connected state) the upper head piece continues the lower head piece to form the bolt head.

[0009] The lower headpiece is preferably directly connected to the locking bar.

[0010] The upper headpiece is located inside the guide mechanism and is slidably guided in a locking channel extending from the interior and opening onto the top of the guide mechanism. The guide mechanism is open to the interior of the guide mechanism on one mounting side (the side of the guide mechanism facing the sliding sash when mounted).

[0011] The guide device is (by means of an assembly movement) placed onto the end face of the sliding sash with its mounting side facing the sash and can be fastened to the sash, e.g., by screwing it in place. The assembly movement can be designed such that the guide device is moved essentially orthogonally (at an angle of 90° ± 5°) to the end face of the sliding sash (parallel to the direction of movement).

[0012] When the guide device is installed (assembly movement), the profile features of the end pieces are facing each other and aligned with each other, so that the end pieces can be connected to each other or are connected to each other when the guide device is placed on the sliding sash (end-side) (pairing of profile features).

[0013] In the proposed sliding door arrangement, the bolt head is divided into a lower head piece and a separate upper head piece, which are coupled together by their profile features when the guide device is mounted on the sliding sash. The lower head piece is connected to the bolt rod guided on the sliding sash, and the upper head piece is slidably mounted in the guide device. When the guide device is mounted on the end face of the sliding sash, the head pieces are connected to each other, thus forming the bolt head, which is connected to the bolt rod.

[0014] The multi-part locking head eliminates the need to first insert the sliding sash into the guide rail at the top with its guide mechanism, then pivot the sash freely and place it onto the track at the bottom. Instead, the sash (at the bottom) can now be securely placed onto the track in a tilted position and then pivoted (at the top) towards the fixed frame. The locking bar is completed by coupling the end pieces of the guide mechanism onto the end face of the sliding sash. Because the guide mechanism engages in the guide rail on the upper frame cross member (guide section) and is attached to the sliding sash, the sliding sash is also guided along the upper frame cross member. This simplifies not only the installation of the sliding sash but also its disassembly, which can be carried out in reverse order, starting with releasing the guide mechanism.Accident risks for fitters can be avoided during both assembly and disassembly.

[0015] The sliding door arrangement can be designed such that the fixed frame has two fixed panels (spaced apart along the direction of movement), between which the sliding panel is positioned when the sliding panel is closed (so-called "Schema G1"). The sliding panel can be moved along the direction of movement in front of at least one of the two fixed panels. It is also conceivable that the sliding panel can be moved in front of both fixed panels. In this case, there can be several (fully open) positions (open position of sliding panel in front of the first fixed panel and open position of sliding panel in front of the first fixed panel). Locking is achieved at the upper frame cross member and / or at the lower frame cross member or at the floor.

[0016] As mentioned above, the sliding sash can be guided by a running mechanism on the lower frame cross member or on the floor. The running mechanism can comprise a track attached to the lower frame cross member or the floor, as well as one or more carriages that are guided on the track, for example, by means of rollers. The carriage(s) are attached to the sliding sash, in particular to its lower frame cross member.

[0017] The sliding sash and the locking mechanism can be operated by means of a handle located on the sash side. When the handle is operated, the locking bar can be moved along its central longitudinal axis.

[0018] The locking bar of the locking device can be displaced between a locked position and an unlocked position. In the locked position, the locking head is displaced towards the upper frame cross member, with the upper head section engaging a locking plate arranged on the upper frame cross member, preferably in the guide rail. In the unlocked position, the locking head is displaced away from the upper frame cross member, with the upper head section disengaging from a locking plate arranged on the upper frame cross member, preferably in the guide rail.

[0019] The sliding sash in question could specifically be a lift-and-slide sash. The lift-and-slide sash can be raised relative to the fixed frame (stationary frame), for example, by means of a handle on the sash side, and in the raised position, it can be moved along the sliding direction relative to the fixed frame, for example, by means of one or more carriages. In this case, the sliding door arrangement can also be referred to as a lift-and-slide door arrangement.

[0020] In principle, it is conceivable that the profile features of the head pieces are arranged on the end faces of the head pieces, i.e., on the end faces of the head pieces oriented along the central longitudinal axis of the locking bar. With such a design, the profile features could, for example, form a locking connection.

[0021] In a preferred embodiment, the end pieces can each extend along a bolt axis, with the profile features extending along a connecting axis orthogonal to the bolt axis. Such an orientation of the profile features (extension along the connecting axis) facilitates simple connection of the end pieces by attaching the guide device. Furthermore, this design contributes to a comparatively stable coupling, as the end pieces overlap along the bolt axis. In addition to the actual profile features (positive locking connection), corresponding contact surfaces can be provided, which offer additional support. The contact surfaces can be arranged along the bolt axis, adjacent to the respective profile feature on one or both sides. The bolt axis can be oriented along or parallel to the central longitudinal axis of the bolt bar.

[0022] Advantageously, one of the end pieces can have a male positive locking element as a profile feature, and the other end piece can have a female positive locking element as a profile feature. This allows for a structurally simple and robust coupling of the end pieces.

[0023] Specifically, the male form-locking element can be designed as a tenon and the female form-locking element as a mortise to accommodate the tenon. This contributes to a particularly simple coupling of the end pieces. The tenon and the mortise can have a circular, elliptical, or n-sided cross-section. A circular cross-section facilitates the insertion of the form-locking elements.

[0024] In a preferred embodiment, at least one projection can be formed adjacent to the female interlocking element, and at least one corresponding recess can be formed adjacent to the male interlocking element to receive the projection. This increases the stability of the connection between the head pieces, since not only the interlocking elements but also at least one recess and one projection engage with each other. The recesses or the projection can be arranged along the locking axis adjacent to the respective interlocking element, preferably one along the locking axis above the respective interlocking element and one below it. Preferably, the recess and the projection can each have a rounded shape. This facilitates the mating of the projection and recess. The projection and the recess can each extend along or parallel to the locking axis.

[0025] Advantageously, the upper headpiece can have a connecting section in which the profile feature, in particular the female positive locking element, is arranged, as well as a transom section adjacent to the connecting section. This contributes to a structurally stable and compact design. The transom section preferably adjoins the connecting section directly. The female positive locking element (e.g., a mortise) and optionally one or more projections can be arranged in the connecting section. The transom section preferably has a larger cross-section than the connecting section. At the free end of the transom section, the cross-section of the transom section can taper, e.g., by means of a sloping surface.

[0026] Advantageously, the lower headpiece (at the proximal end) can have a coupling section for connecting to the locking bar and (at the distal end) a connecting section in which the profile feature, in particular the male positive locking element, is located. This contributes to a structurally simple connection between the locking bar and the upper headpiece. The connecting section can contain the male positive locking element (e.g., a pin) and optionally one or more recesses for receiving the projection. The cross-section of the connecting section can be tapered compared to the cross-section of the coupling section.

[0027] Specifically, the lower headpiece between the coupling section and the connecting section can have a central section with a slot formed in the central section. This slot is designed such that a pin extending inside the guide assembly can pass through it for a fastening screw to secure the guide assembly (headpieces connected to each other and guide assembly attached to the sliding sash). In this way, the fastening of the guide assembly to the sliding sash is not impaired by the headpieces, as the pin for a fastening screw can penetrate the lower headpiece into its central section. Furthermore, the central section can be guided by the pin. The pin can be flattened in two opposing sections, particularly if it has an annular cross-section. The slot extends along or parallel to the bolt axis.The slot is dimensioned in length such that the pin can penetrate it regardless of the position of the locking bar (the range between the locked and unlocked positions). As already mentioned, the pin may have a passage for a fastening screw to attach the guide device to the end face of the sash (screw guide channel).

[0028] In a preferred embodiment, a locking plate can be attached to the upper frame cross member, particularly in the guide rail there, with which the upper headpiece engages when the sash is closed (and, if a locking bar is present, in the locked position). This contributes to a stable and reliable locking mechanism. The locking plate can have several locking projections, preferably tapered in cross-section. Each locking projection can have a contact surface that corresponds to the inclined surface of the locking section of the upper headpiece (a parallel arrangement is conceivable).

[0029] Advantageously, the upper headpiece, the lower headpiece, and / or the locking plate can be made of stainless steel, particularly by investment casting. This design using high-quality materials contributes to stability, safety, and sturdiness.

[0030] Specifically, the guide device can have a guide roller, preferably mounted on a roller bearing, or a sliding block on its upper side, particularly in a guide section (projecting into the guide rail on the upper frame cross member). This contributes to smooth and quiet guidance of the sliding sash along the upper frame cross member. The guide elements are each designed to be guided in a (downwardly open) guide rail on the upper frame cross member.

[0031] Advantageously, the locking rod can be guided on the sliding sash by means of a retaining plate, wherein the retaining plate has a fastening section for attaching the retaining plate to the sliding sash, an intermediate section extending orthogonally to the fastening section, and a guide section extending parallel to the fastening section in which the connecting rod is guided in a single pass. This contributes to a structurally simple and stable guidance of the locking rod on the sliding sash.

[0032] The guide described above can be arranged on the (first) vertical frame member, where the handle for operating the locking mechanism is located. Independently of this, the sliding door assembly can have a further guide for guiding the sliding sash in the guide rail on the upper frame member, which is arranged on a second vertical frame member (e.g., on the vertical frame member that does not have a handle for operating the locking mechanism). Thus, the sliding sash can be guided at both ends on the upper frame member.

[0033] The aforementioned problem is also solved by a method with the features of the subordinate claim.

[0034] This procedure is used to assemble a sliding door assembly with one or more of the aspects described above. The procedure comprises the following steps: Mounting the fixed frame on a building end, inserting the sliding sash into the fixed frame, wherein the sliding sash is placed in a tilted position relative to the fixed frame with its lower sash cross member, in particular by means of a running device, onto a lower frame cross member of the fixed frame, pivoting the sliding sash from the tilted position towards the fixed frame, so that an upper sash cross member and the guide rail attached to the upper frame cross member of the fixed frame are aligned with each other, placing the guide device with the mounting side onto the end face of the sliding sash, wherein the end pieces are connected to each other by their mutually facing and aligned profile features when the guide device is placed onto the sliding sash, and fastening the guide device to the sliding sash.

[0035] Regarding the advantages that can be achieved in this way, reference is made to the relevant explanations concerning the sliding door arrangement.

[0036] In more detail, the procedure can be formulated as follows: Procedure for assembling a sliding door assembly, in particular a sliding door assembly with one or more of the aspects described above, comprising the following steps: Providing and installing a fixed frame at a building end, providing a sliding sash with a locking bar guided on the sliding sash and a lower head of a locking bar connected to the locking bar, inserting the sliding sash into the fixed frame, wherein the sliding sash, in a tilted position relative to the fixed frame, is placed with its lower sash cross member, in particular by means of a running device, onto a lower frame cross member, pivoting the sliding sash from the tilted position towards the fixed frame so that an upper sash cross member and a guide rail attached to an upper frame cross member of the fixed frame are aligned with each other, and providing a guide device for guiding the sliding sash on the upper frame cross member.wherein an upper headpiece of the bolt head is arranged in an interior of the guide device and is slidably guided in a bolt channel extending from the interior and opening onto a top surface of the guide device, and wherein the guide device is open towards the interior on a mounting side, the end face of the guide device is placed with the mounting side onto the sliding sash, wherein the headpieces are connected to each other when the guide device is placed onto the sliding sash, in particular by mutually facing and aligned profile features of the headpieces, and the guide device is fastened to the sliding sash.

[0037] The measures described in connection with the sliding door arrangement and / or those discussed below can be used for further development.

[0038] The invention is explained in more detail with reference to the figures, where identical or functionally identical features are designated with identical reference numerals, possibly only once. The figures show: Fig. 1 shows an embodiment of the sliding door arrangement in a schematic side view; Fig. 2 shows an enlarged and partially cutaway partial view of the sliding door arrangement. Figure 1 , with the locking device in the release position; Fig. 3 an enlarged and partially cutaway partial view of the sliding door assembly made of Figure 1 analogous to Figure 2 , where the locking device is in the locked position; Fig. 4 shows a further enlarged and partially cutaway view of the sliding door assembly. Figure 1 , which illustrates the mounting of the guide device on the end face of the sliding sash; and Fig. 5a-e several components of the sliding door assembly made of Figure 1 .

[0039] Figure 1Figure 1 shows a schematic side view of an embodiment of the sliding door arrangement, which is generally designated by reference numeral 10.

[0040] The sliding door assembly 10 has a fixed frame 12 that can be mounted on a building end (not shown). The fixed frame 12 has an upper frame cross member 13, a lower frame cross member 14, and two vertical frame members 15, 16. The fixed frame 12 also has two fixed panels 17, 18, which, as in this example, can be glazed (glazed fixed panels).

[0041] The sliding door arrangement 10 further comprises a sliding leaf 20, which in the example can be moved between a closed position (shown) and an open position (sliding leaf in front of the second fixed panel 18; not shown) along a displacement direction VR. The fixed panels 17, 18 are spaced apart from each other, with the sliding leaf 20 in the closed position being located between the fixed panels 17, 18 along the displacement direction VR (so-called "scheme G1"; cf. Fig.1 ).

[0042] The sliding sash 20 has an upper sash mullion 21, a lower sash mullion 22, and two vertical sash mullions 23, 24. In the example, a handle 25 for operating the sliding sash 20 is located on the vertical sash mullion 23.

[0043] A guide rail 26, open downwards along the direction of gravity g, is arranged on the upper frame cross member 13 (in Figure 1(only shown schematically). A guide rail 27 is arranged on the lower frame cross member 14 (only shown schematically). The sliding sash 20 can be moved on the guide rail 27 by means of (only schematically indicated) carriages 28, 29. In addition, the sliding sash 20 can be moved by means of (in Figure 1 The guide devices 30, 31 (also only schematically indicated) are guided in the guide rail 26. The running rail 27 and the carriages 28, 29 together form a running device.

[0044] In this example, the sliding sash 20 is designed as a lift-and-slide sash, which can be lifted relative to the fixed frame 12 by means of the handle 25 (and a fitting not shown) and, in the lifted position, can be moved along the sliding direction VR relative to the fixed frame 12. The sliding door assembly 10 can therefore also be referred to as a lift-and-slide door assembly. For the sake of simplicity, the terms "sliding sash" and "sliding door assembly" will be used below.

[0045] Figure 2 shows an enlarged and partially cut-away partial view of the sliding door arrangement 10 from Figure 1 .

[0046] The sliding door assembly 10 further comprises a locking device 32 for locking the sliding sash 20 to the upper frame cross member 13 with respect to the direction of gravity g. The locking device 32 in turn comprises a locking bar 33 guided on the sliding sash 20 with a locking head 34 (which can be coupled to or is coupled with the locking bar) facing the upper frame cross member 13.

[0047] As already indicated, the guide device 30 serves to guide the sliding sash 20 in the guide rail 26 attached to the upper frame cross member 13. Thus, when attached to the sliding sash 20, the guide device 30 can guide the sliding sash 20 in the guide rail 26. The guide device 30 can have a guide section 30' that projects into the guide rail 26.

[0048] The bolt head 34 has a lower head piece 35 and an upper head piece 36. The head pieces 35 and 36, in turn, have corresponding profile features P by means of which the head pieces 35 and 36 can be positively connected to one another in such a way that, in the connected state, the upper head piece 36 extends the lower head piece 35 to form the bolt head 34 (cf. Fig.2 ).

[0049] In this example, the lower head piece 35 is directly connected to the locking rod 33, e.g. by screwing (external thread on locking rod 33 and internal thread on the lower head piece 35).

[0050] The upper head piece 36 is arranged in an interior space 37 of the guide device 30 and is slidably guided in a locking channel 39 extending from the interior space 37 and opening onto a top surface 38 of the guide device. The guide device 30 is open to the interior space 37 on a mounting side 40 (the side of the guide device 30 facing the sliding sash 20 when mounted).

[0051] The guide device 30 is installed by means of an assembly movement (see arrow MB in Fig.4 The guide device 30 can be placed on the end face of the sliding sash 20 with its mounting side 40 and fastened to the sliding sash 20, e.g., by screwing it in place. The mounting movement MB can be designed such that the guide device 30 is moved essentially orthogonally (angle of 90° ± 5°) to the end face 23' of the sliding sash 20 (parallel to the direction of movement VR) towards the end face 23' of the sliding sash 20.

[0052] When the guide device 30 is placed on the sliding wing (assembly movement MB), the profile features P of the end pieces 35, 36 are facing each other and aligned with each other, so that the end pieces 35, 36 can be connected to each other or are connected to each other when the guide device 30 is placed on the sliding wing 20 (end-side) (pairing of the profile features P).

[0053] The guide device 30 has a guide element on its upper surface 38 at the connecting section 30', which in this example is designed as a roller-bearing guide roller 42. This promotes low-friction and low-noise guidance in the guide rail 26.

[0054] A locking plate 44 is attached to the upper frame cross member 13, in this example in the guide rail 26. The locking device 32 can be actuated by means of the handle 25. By actuating the handle 25, the locking bar 33 can be moved between a locking position (see figure). Fig.3) and an unlocking position (see Fig.2 ) are moved. In the locked position (see below). Fig.3 The bolt head 34 is displaced towards the upper frame cross member 13, with the upper head piece 36 engaging with the bolt plate 44. In the unlocked position (see Fig.2 The bolt head 34 is displaced away from the upper frame cross member 13, with the upper head piece 36 disengaging from the bolt plate 44. In this example, the bolt plate 44 has several bolt projections 45 that taper to a point in cross-section (see figure). Fig.3 and 5e ).

[0055] The locking rod 33 is guided on the sliding sash 20 by means of a retaining plate 46, wherein the retaining plate 46 has a fastening section 47 for fastening the retaining plate 46 to the sliding sash 20, an intermediate section 48 extending orthogonally to the fastening section and a guide section 49 extending parallel to the fastening section 47, in which the connecting rod 33 is guided in a passage 50.

[0056] Inside the interior 37 of the guide device 30, a pin 52 extends for a fastening screw to attach the guide device 30 to the end face of the sliding sash 30. The pin has a passage 54 for a fastening screw (screw guide channel; cf. Fig.3 and 5a ).

[0057] The head pieces 35, 36 each extend along a bar axis R, R', wherein the profile features P each extend along a connecting axis V, V' orthogonal to the bar axis R, R' (cf. Fig. 4 , 5a and 5b ).

[0058] In the example, one of the head pieces 35, 36 has a male positive locking element M as profile feature P, and the other head piece 36, 35 has a female positive locking element W as profile feature P (cf. Fig.4 Specifically, the male positive locking element M is designed as a pin 56 and the female positive locking element W as a mortise 58 for the corresponding reception of the pin 56. In the example, the male positive locking element M is formed on the lower head piece 35 and the female positive locking element W on the upper head piece 36 (see, among others, the following). Fig.4 , 5b and 5c ).

[0059] Adjacent to the female positive locking element W, two, preferably rounded, projections 60, 61 are formed on the upper head piece 36 in the example, wherein the projection 60 is arranged along the bolt axis R' above the female positive locking element W and the projection 61 is arranged along the bolt axis R' below the female positive locking element W (cf. Fig.5b ).

[0060] Adjacent to the male positive locking element M, two, preferably rounded, corresponding recesses 62, 63 are formed on the lower head piece 35 in the example for receiving the respective projection 60, 61, wherein the recess 62 is arranged along the bolt axis R above the male positive locking element M and the recess 63 is arranged along the bolt axis R below the male positive locking element M (cf. Fig.5c ).

[0061] The upper head piece 36 has a connecting section 64 in which, in the example, the female positive locking element W and the projections 60, 61 are arranged, as well as a bar section 65 adjacent to the connecting section 64 (see Fig.5b The bar section 65 in the example is directly adjacent to the connecting section 64. The bar section 65 has a larger cross-section than the connecting section 64. At the free end of the bar section 65, the cross-section of the bar section 64 can taper, for example by means of a sloping surface 66.

[0062] The lower head piece 35 has (at the proximal end) a coupling section 67 for coupling with the locking bar 33 and (at the distal end) a connecting section 68 in which the male positive locking element M and the recesses 62, 63 are arranged. The cross-section of the connecting section 68 is tapered compared to the cross-section of the coupling section 67.

[0063] The lower head piece 35 has a central section 69 between coupling section 67 and connecting section 68, wherein a slot 70 is formed in the central section 69, which is designed such that the pin 52 extending in the interior 37 of the guide device 30 can penetrate the slot 70 for a fastening screw to secure the guide device 30 (head pieces 35, 36 connected to each other and guide device 30 attached to the sliding wing 20; cf. Fig.2 and 5a ).

[0064] The central section 69 can be guided on the pin 52. The pin 52 can be flattened into two opposing pin sections, particularly starting from an annular cross-section (cf. Fig.5a ).

[0065] The elongated hole 70 extends along or parallel to the bolt axis R. The length of the elongated hole 70 is such that the pin 52 can penetrate the elongated hole 70 regardless of the position of the bolt rod 33 (position range between locking position and unlocking position).

[0066] The guide device 30, the upper head piece 36, the lower head piece 35 and / or the locking plate 44 can be made of stainless steel, in particular by investment casting.

[0067] As explained above, the multi-part locking head 34 eliminates the need to first insert the sliding sash 20 with its guide device 30 into the guide rail 26 at the top and then pivot the sliding sash 20 freely and place it on the running rail 27 at the bottom.

[0068] Instead, the sliding sash 20 (below) can now first be securely placed on the guide rail 27 in a tilted position and then (above) pivoted towards the fixed frame 12, whereby the locking bar 33 is completed by coupling the end pieces 35, 36 through the placement of the guide device 30 on the end face of the sliding sash 20. Since the guide device 30 engages in the guide rail 26 on the upper frame cross member 13 (guide section 30') and is attached to the sliding sash 20, the guidance of the sliding sash 20 on the upper frame cross member 13 is also established.
