Description

[0001] The invention relates to a sliding door arrangement with a fixed frame and a sliding leaf 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 independent claim.

[0002] Sliding door assemblies and sliding panels of the type mentioned above are known from the prior art. Depending on the panel size, the weight of such panels can sometimes be 400 kg (kilograms) or more. Such sliding panels are typically guided on the fixed frame in two ways: firstly, by means of roller-mounted guides on a lower frame cross member or on the floor, and secondly, by means of a corresponding guide element in a guide rail attached to an upper frame cross member of the fixed frame.

[0003] In order to be installed in a fixed frame, such a sash must first be connected to the guide on the upper cross member of the frame and to the guide rail there. It can then be placed freely on the guide rail using the bogies, tilting downwards (first insert it into the guide rail at the top, then place it onto the guide rail at the bottom). This is particularly time-consuming and cumbersome with heavy sashes. For example, due to space constraints, the locking mechanism must be installed before the sash is inserted. This not only complicates installation, but also makes subsequent disassembly, e.g., for maintenance or repair, difficult and time-consuming. Due to the complex handling and the heavy sash weight, there is a significant risk of injury for fitters during installation and disassembly of such sashes.

[0004] The invention is based on the object of enabling simple and safe installation in a sliding door arrangement.

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

[0006] The sliding door assembly further comprises a locking device for locking the sliding sash to a frame cross member of the fixed frame that is located upper relative to the direction of gravity g. The locking device, in turn, comprises a locking bar guided on the sliding sash with a locking head (which can be coupled to the locking bar or is coupled to it and) facing the upper frame cross member. The locking device can be formed 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 sash in a guide rail attached to the upper frame cross member. The guide device can penetrate the guide rail with a guide section (e.g., a U-shaped cross-section open at the bottom). When attached to the sliding sash, the guide device can guide the sliding sash along the upper frame cross member (guide rail).

[0008] The locking head comprises a lower headpiece and an upper headpiece. The headpieces, in turn, have corresponding profile features (connecting contours) by means of which the headpieces can be connected to one another in a form-fitting manner such that (when connected) the upper headpiece continues the lower headpiece to form the locking head.

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

[0010] The upper head piece is located in an interior space of the guide mechanism and is slidably guided in a locking channel extending from the interior space and opening at the top of the guide mechanism. The guide mechanism is open to the interior space of the guide mechanism on one mounting side (the side of the guide mechanism facing the sliding sash when installed).

[0011] The guide device can be placed (using a mounting movement) with its mounting side facing the front of the sliding sash and secured to the sliding sash, e.g., by screwing. The mounting movement can be designed such that the guide device is moved toward the front of the sliding sash essentially orthogonally (at an angle of 90° ± 5°) to the front of the sliding sash (parallel to the sliding direction).

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

[0013] In the proposed sliding door arrangement, the locking head is divided into a lower headpiece and a separate upper headpiece, which are coupled together by their profile features when the guide device is placed on the sliding sash. The lower headpiece is connected to the locking bar guided on the sliding sash, and the upper headpiece is slidably mounted in the guide device. When the guide device is placed on the front of the sliding sash, the headpieces are connected to each other, thus forming the locking head, which is connected to the locking bar.

[0014] The multi-part locking head eliminates the need to first insert the sliding sash with its guide device into the guide rail at the top and then pivot the sliding sash freely and place it on the track at the bottom. Instead, the sash can now first be placed securely in a tilted position on the track (below) and then pivoted (above) towards the fixed frame. By placing the guide device on the front of the sliding sash, the locking bar is completed by coupling the head pieces. Because the guide device engages in the guide rail on the upper frame cross member (guide section) and is fastened to the sliding sash, the sliding sash is also guided on the upper frame cross member. This not only simplifies the installation of the sliding sash, but also its disassembly, which can be carried out in the reverse order, starting with loosening the guide device.Risks of accidents 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 sliding direction), between which the sliding sash is arranged when the sliding sash is in the closed position (so-called "Scheme G1"). The sliding sash can be displaced along the sliding direction in front of at least one of the two fixed panels. It is also conceivable for the sliding sash to be displaced in front of both fixed panels. This allows for several (fully) open positions (sliding sash open position in front of the first fixed panel and sliding sash open position in front of the first fixed panel). Locking is provided at the upper frame cross member and / or at the lower frame cross member or at the floor.

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

[0017] The sliding sash and the locking mechanism can be operated using 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 locking position and an unlocking position. In the locking position, the locking head is displaced toward the upper frame cross member, with the upper head piece engaging with a locking plate arranged on the upper frame cross member, preferably in the guide rail. In the unlocking position, the locking head is displaced away from the upper frame cross member, with the upper head piece disengaging from a locking plate arranged on the upper frame cross member, preferably in the guide rail.

[0019] The sliding sash can specifically be a lift-and-slide sash. The lift-and-slide sash can be lifted relative to the fixed frame (stationary frame), for example, using a handle on the sash, and can be moved relative to the fixed frame in the raised position along the sliding direction, for example, using 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 front side of the head pieces, i.e., at the front ends 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 snap-in connection.

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

[0022] Advantageously, one of the headpieces can have a male form-locking element as a profile feature, and the other headpiece can have a female form-locking element as a profile feature. This allows for a structurally simple and robust coupling of the headpieces.

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

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

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

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

[0027] Specifically, the lower head piece can have a central section between the coupling section and the connecting section, wherein an elongated hole is formed in the central section, which is designed such that a pin extending in the interior of the guide device for a fastening screw for fastening the guide device can penetrate the elongated hole (head pieces connected to one another and guide device fastened to the sliding sash). In this way, the possibility of fastening the guide device to the sliding sash is not impaired by the head pieces, since the pin for a fastening screw can penetrate the lower head piece in its central section. In addition, the central section can be guided on the pin. The pin can be flattened in two opposite pin sections, in particular starting from a circular cross-section. The elongated hole extends along or parallel to the latch axis.The slot is dimensioned so that the pin can penetrate it regardless of the position of the locking bar (adjustment range between the locked and unlocked positions). As already mentioned, the pin can have a passage for a fastening screw for attaching the guide device to the front 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 can engage when the sash is in the closed position (and, in the case of a locking bar, in the locked position). This contributes to stable and reliable locking. The locking plate can have several locking projections, preferably tapered in cross-section. The locking projections can each 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 uses high-quality materials, which contributes to stability, safety, and durability.

[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 (which extends into the guide rail on the upper frame cross member). This contributes to low-friction and low-noise guidance of the sliding sash on the upper frame cross member. The guide elements are each designed such that they can be guided in a (downwardly open) guide rail on the upper frame cross member.

[0031] The locking bar can be conveniently 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 coupling rod is guided in a passage. This contributes to a structurally simple and stable guide of the locking bar on the sliding sash.

[0032] The guide device described above can be arranged on the (first) vertical wing member, on which the handle for actuating the locking device is located. Independently of this, the sliding door arrangement can have a further guide device for guiding the sliding wing in the guide rail on the upper frame cross member, which is arranged on a second vertical wing member (e.g., on the vertical wing member on which there is no handle for actuating the locking device). Thus, the sliding wing can be guided at both ends on the upper frame cross member.

[0033] The problem mentioned at the outset is also solved by a method having the features of the independent claim.

[0034] The method is used to assemble a sliding door assembly having one or more of the aspects described above. The method comprises the following steps: Mounting the fixed frame to a building closure, inserting the sliding sash into the fixed frame, wherein the sliding sash is placed with its lower sash cross member, in particular by means of a running device, on a lower frame cross member of the fixed frame in a tilted position relative to 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 one another, placing the guide device with the mounting side onto the sliding sash on the front side, wherein the head pieces are connected to one another by their mutually facing and aligned profile features when the guide device is placed on the sliding sash, and fastening the guide device to the sliding sash.

[0035] With regard to the advantages that can be achieved in this way, reference is made to the relevant comments on the sliding door arrangement.

[0036] In more detail, the method can be formulated as follows: Method for assembling a sliding door arrangement, in particular a sliding door arrangement with one or more of the aspects described above, comprising the steps: Providing and installing a fixed frame at a building closure, providing a sliding sash with a locking bar guided on the sliding sash and a lower head piece of a locking head 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, on 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 head piece of the locking head is arranged in an interior space of the guide device and is displaceably guided in a locking channel extending from the interior space and opening out at an upper side of the guide device, and wherein the guide device is open towards the interior space on a mounting side, frontally placing the guide device with the mounting side onto the sliding sash, wherein the head pieces are connected to one another when the guide device is placed onto the sliding sash, in particular by mutually facing and aligned profile features of the head pieces, and fastening the guide device to the sliding sash.

[0037] For further design, the measures described in connection with the sliding door arrangement and / or those discussed below can be used.

[0038] The invention is explained in more detail with reference to the figures, in which identical or functionally equivalent features are provided with identical reference numerals, if necessary, but only once. They show: Fig.1 shows an embodiment of the sliding door arrangement in a schematic side view; Fig.2 shows an enlarged and partially sectioned partial view of the sliding door arrangement from Figure 1 , wherein the locking device is in the release position; Fig.3 an enlarged and partially sectioned partial view of the sliding door arrangement from Figure 1 analogous to Figure 2 , the locking device being in the locking position; Fig.4 a further enlarged and partially sectioned partial view of the sliding door arrangement from Figure 1 , which illustrates the placement of the guide device on the front side of the sliding sash; and Fig.5a-e several components of the sliding door assembly from Figure 1 .

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

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

[0041] The sliding door assembly 10 further comprises a sliding leaf 20, which, in the example, is movable between a closed position (shown) and an open position (sliding leaf in front of the second fixed panel 18; not shown) along a sliding direction VR. The fixed panels 17, 18 are spaced apart from one another, with the sliding leaf 20 in the closed position located between the fixed panels 17, 18 along the sliding direction VR (so-called "Scheme G1"; see Fig. Fig.1 ).

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

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

[0044] In this example, the sliding sash 20 is designed as a lift-and-slide sash that can be lifted relative to the fixed frame 12 by means of the handle 25 (and a fitting not shown) and, in the raised position, can be moved relative to the fixed frame 12 along the sliding direction VR. 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" are used below.

[0045] Figure 2 shows an enlarged and partially sectioned 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 leaf 20 to the upper frame cross member 13 relative to the direction of gravity g. The locking device 32, in turn, comprises a locking bar 33 guided on the sliding leaf 20 with a locking head 34 (which can be coupled to the locking bar or is coupled to it and) 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 locking head 34 has a lower head piece 35 and an upper head piece 36. The head pieces 35, 36, in turn, have corresponding profile features P, by means of which the head pieces 35, 36 can be connected to one another in a form-fitting manner such that, in the connected state, the upper head piece 36 continues the lower head piece 35 to form the locking head 34 (cf. Fig.2 ).

[0049] In the example, the lower head piece 35 is directly connected to the locking bar 33, e.g. by screwing (external thread on locking bar 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 at an upper side 38 of the guide device. The guide device 30 is open toward the interior space 37 on a mounting side 40 (the side of the guide device 30 facing the sliding sash 20 in the mounted state).

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

[0052] When the guide device 30 is placed on the sliding sash 20 (assembly movement MB), the profile features P of the head pieces 35, 36 face each other and are aligned with each other, so that the head 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 sash 20 (front-side).

[0053] The guide device 30 has a guide element on its upper side 38 at the connecting section 30', which in the 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 the 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 Fig.3) and an unlocking position (see Fig.2 ) can be moved. In the locking position (see Fig.3 ), the locking head 34 is shifted towards the upper frame cross member 13, with the upper head piece 36 engaging with the locking plate 44. In the unlocked position (cf. Fig.2 ), the locking head 34 is displaced away from the upper frame cross member 13, whereby the upper head piece 36 is disengaged from the locking plate 44. In the example, the locking plate 44 has several locking projections 45 with a pointed cross-section (cf. Fig.3 and 5e ).

[0055] The locking rod 33 is guided on the sliding sash 20 by means of a holding plate 46, wherein the holding plate 46 has a fastening section 47 for fastening the holding 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 coupling rod 33 is guided in a passage 50.

[0056] In the interior space 37 of the guide device 30, a pin 52 extends for a fastening screw for fastening the guide device 30 to the front side of the sliding sash 30. The pin has a passage 54 for a fastening screw (screw guide channel; see Fig.3 and 5a ).

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

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

[0059] Adjacent to the female form-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 locking axis R' above the female form-locking element W and the projection 61 is arranged along the locking axis R' below the female form-locking element W (cf. Fig.5b ).

[0060] Adjacent to the male form-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 locking axis R above the male form-locking element M and the recess 63 is arranged along the locking axis R below the male form-locking element M (cf. Fig.5c ).

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

[0062] The lower headpiece 35 has (at the proximal end) a coupling section 67 for coupling to the locking bar 33 and (at the distal end) a connecting section 68 in which the male form-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 the coupling section 67 and the connecting section 68, wherein an elongated hole 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 for a fastening screw for fastening the guide device 30 can penetrate the elongated hole 70 (head pieces 35, 36 connected to one another and guide device 30 fastened to the sliding sash 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 opposite pin sections, in particular starting from a circular cross-section (cf. Fig.5a ).

[0065] The elongated hole 70 extends along or parallel to the locking axis R. The elongated hole 70 is dimensioned in its length such that the pin 52 can penetrate the elongated hole 70 regardless of the position of the locking rod 33 (adjustment 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 precision casting.

[0067] As already 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 to pivot the sliding sash 20 freely and place it on the guide rail 27 at the bottom.

[0068] Instead, the sliding sash 20 (below) can now first be securely placed in a tilted position on the guide rail 27 and then (above) pivoted toward the fixed frame 12. By placing the guide device 30 on the front of the sliding sash 20, the locking bar 33 is completed by coupling the head pieces 35, 36. Since the guide device 30 engages in the guide rail 26 on the upper frame cross member 13 (guide section 30') and is fastened to the sliding sash 20, the sliding sash 20 is also guided on the upper frame cross member 13.

[0069] A method for assembling the sliding door assembly having one or more of the features described above may proceed as described above.
