Description

[0001] The invention relates to a folding sliding door according to the preamble of claim 1.

[0002] Folding sliding doors consist of at least two or more vertically oriented door leaf elements, typically installed in a vertically oriented wall within a building. These elements are connected to each other and, in one area, to a frame via hinged joints, and when opened, they slide together in a zigzag pattern. This results in a large opening width, with the door leaf elements positioned at the edge of the opening to save space when folded.

[0003] Folding sliding doors with flush-mounted sash frames – which offer a particularly attractive visual appearance when closed – typically employ a soft, large-volume seal or corresponding sealing profile above and / or below the horizontal profiles of the sash frame, facing the frame, to ensure a sufficiently high level of water and air tightness when the folding sliding door is closed. These seals must maintain water and air tightness at all times, even with significant manufacturing tolerances, building settlement, or profile deformation due to weight and wind loads.

[0004] At the same time, the seal must not be too stiff / hard, so that the operating forces of the folding sliding door, especially during the closing process, do not become too high. However, increased sealing counter-pressure is required in the locking area of ​​the folding sliding door to eliminate play between the components. This play is necessary to allow slight movement between the components (locking mechanism and guide, guide rollers and frame) while simultaneously compensating for manufacturing tolerances and the thickness of any surface protective coating.

[0005] Therefore, the necessary sealing counter-pressure is often lacking in the area of ​​the locking points, meaning the seal does not optimally seat against a counter-sealing surface on a frame, which can cause rattling noises that are undesirable. Furthermore, the sealing properties of the seal may also be compromised.

[0006] The invention therefore aims to create a folding sliding door that reduces these problems.

[0007] This problem is solved with the subject matter according to claim 1.

[0008] Accordingly, a folding sliding door is created which can be installed in a vertical orientation in a building opening, wherein the folding sliding door has at least the following features; a building-fixed frame in which at least two or more folding sliding panels are provided, wherein a first folding sliding panel is pivotally connected to the frame, wherein this first folding sliding panel is pivotally connected to the next folding sliding panel, and wherein each further folding sliding panel is also pivotally connected to the preceding folding sliding panel, and wherein at least one of the folding sliding panels is furthermore guided slidably and pivotably on the frame, so that the folding sliding panels are movable between a folded-open position and a closed position, wherein each folding sliding panel has a sash frame into which a surface element is inserted, wherein at least one sealing profile is provided to seal a horizontal rebate space between the respective sash frame of the folding sliding panel and the frame against the frame, and wherein at least one sealing profile is supported and stabilized in sections by at least one pressure element.

[0009] This results in a structurally simple and therefore advantageous increased sealing counter-pressure of the sealing profile against a counter-sealing surface on the frame.

[0010] In a particularly simple design, at least one sealing profile can be supported and stabilized only partially by at least one pressure element. The pressure element is then only provided where necessary. This makes it possible, in particular, to increase the required pressure when closing the door only minimally, or at least not noticeably.

[0011] It can preferably be provided that the sealing profile is supported and stabilized by at least one pressure element – ​​preferably only – in the area of ​​one or more locking elements optionally provided on the respective sash frame. This results in a simple and therefore advantageous increase in sealing counter-pressure on the counter-sealing surface only at positions where locking elements are provided. The sealing profile is thus stabilized only where this is necessary due to the typically greater structural play in these areas. Since the pressure element is designed to be relatively short and not very large, the forces involved in closing the respective folding sliding sash are only minimally increased.

[0012] Furthermore, it is a preferred embodiment that in the X direction (relative to the closed state of the folding sliding door) the respective sealing profile is only partially supported and stabilized by a respective pressure element in front of and behind areas in which a respective folding sliding leaf is articulated to the next folding sliding leaf by one or more door hinges.

[0013] In another preferred embodiment, it is also conceivable that at least one pressure element is provided along the entire length of the at least one sealing profile. In this case, the pressure on the sealing profile can be provided not as a constant force along its entire length, but as a variable force, and only where a higher pressure is required. Outside these areas, the pressure can be lower than in the areas of increased pressure, in particular by more than 50%, and possibly even approach zero. It can preferably be provided that the pressure is again increased by the at least one pressure element in the area of ​​one or more locking elements, which may be provided on the respective sash frame, compared to adjacent sections of the pressure element.However, it can also be provided that the increased pressure is implemented section by section in front of and behind areas where each folding sliding sash is articulated to the next by one or more hinges. In particular, it can also be provided that the pressure is increased or applied over less than 40% of the length of the pressure element or the corresponding sealing profile. In this way, it is also possible to ensure that the required pressure when closing the door is not noticeably increased, or not significantly so. This can be achieved through appropriate design.

[0014] It is preferably provided that, when the respective sash frame is closed, a free sealing lip of the respective sealing profile is supported by the respective pressure element and pressed against the counter-sealing surface on the frame. The increased sealing counter-pressure is then generated by the fact that, when the respective sash frame is closed, a sealing lip of the sealing profile is essentially supported by the pressure element and pressed against the counter-sealing surface. The sealing counter-pressure is thus increased in a simple way where it is needed: by attaching an element, e.g., made of plastic, behind the seal (e.g., clamped and screwed in place) and supporting the sealing profile.

[0015] It may be provided that the respective pressure element and the respective sealing profile are attached to the wing frame of the respective folding sliding wing and that the pressure element rests against the sealing lip - hereinafter also referred to as the web - with an area projecting upwards from the wing frame.

[0016] In a preferred embodiment, the frame and the sash frame are each composed of profiles forming the frame shape. Furthermore, these profiles may be composite profiles, each comprising at least one metal shell and an insulating web.

[0017] It may also be provided that at least one of the folding sliding door leaves is guided slidably on the frame by a running and / or support device.

[0018] And according to a preferred embodiment, the pressure element may be aligned essentially parallel to the sealing profile. This results in a space-saving and efficient alignment of the pressure element.

[0019] According to a further advantageous embodiment of the invention, the pressure element can be provided with a fastening section. This allows the pressure element to be easily attached to a corresponding frame profile, in particular the sash frame.

[0020] According to a further, particularly preferred embodiment of the invention, the fastening section may also have a base web to which two clamping webs are integrally formed, which may be oriented obliquely downwards with respect to the base web. This results in a structurally simple and space-saving fastening of the pressure element.

[0021] An advantage is that the two clamping lugs can be designed to clamp the pressure element in the area of ​​an insulating web of the frame profile or the respective sash frame, thereby creating a positive and force-fit connection between the respective frame profile and the pressure element. This structurally simple, combined positive and force-fit fastening of the pressure element to the respective frame profile ensures a particularly robust attachment.

[0022] According to a further advantageous embodiment of the invention, the positive locking is achieved by the clamping lugs engaging in a geometrically corresponding contour in the respective insulating web. This results in a structurally simple and space-saving positive locking mechanism.

[0023] According to a particularly preferred embodiment of the invention, two side webs, which point substantially obliquely upwards with respect to the base web and outwards with respect to the respective frame or sash frame, are integrally connected to the base web. A particularly rigid structure is created by this preferably integral connection of the side webs to the base web.

[0024] According to a further, particularly preferred embodiment of the invention, the fastening section may also have a support rib to which the two side ribs are integrally formed, the support rib being arranged parallel to the base rib and vertically spaced upwards with respect to the base rib. The integral connection of the side ribs to the support rib creates a particularly rigid structure.

[0025] According to a further advantageous embodiment of the invention, the base web, the two side webs, and the support web can form a closed, block-like profile with a parallelogram-like cross-sectional geometry, which is traversed by a hollow chamber. The block-like profile provides a particularly rigid geometry, while the hollow chamber advantageously saves material.

[0026] A further advantage is that the sealing-side side rib or sealing lip is extended in one piece to form a first pressure section, whereby the first pressure section runs obliquely upwards with respect to the base rib and, after a bend, terminates freely in a second pressure section, essentially vertically upwards. This provides particularly effective support and stabilization of the sealing profile.

[0027] According to a further, particularly preferred embodiment of the invention, the second, vertically upward-directed pressure section may also support the sealing profile in such a way that at least the inner web and the free end of the inner web, when the respective sash frame or the frame is closed, extend vertically against a counter-sealing surface on the respective sash frame or the frame and accordingly conform to the counter-sealing surface on the respective sash frame or the frame without forming a kink, and are thereby supported and stabilized by the second pressure section of the pressure element. This provides optimal support for the sealing profile and optimizes its sealing effect, as well as generating increased sealing counter-pressure.

[0028] It is also advantageous if, in an optional design, the pressure element can be spread open by a screw in such a way that the two clamping lugs are pressed forcefully against the geometrically corresponding contour in the respective insulating bar. This creates a simple force-fit connection, the clamping force of which can be advantageously adjusted by the screw.

[0029] According to a particularly preferred embodiment of the invention, the pressure element is spread open by the screw, which is screwed into a slot extending perpendicular to the parallelogram-like cross-sectional geometry in the base web of the mounting section of the pressure element. This provides an alternative, easily implemented force-fit connection, the clamping force of which is advantageously adjustable by the screw and which saves installation space.

[0030] According to a further, particularly preferred embodiment of the invention, the second pressure section of the pressure element may also have a slot into which a screw can be screwed, thereby widening the slot. This allows the sealing back pressure to be advantageously adjusted continuously.

[0031] Further advantageous embodiments of the invention can be found in the remaining dependent claims.

[0032] The invention is described in more detail below with reference to several exemplary embodiments and the drawings. The invention is not limited to these exemplary embodiments, but can also be implemented in other ways, either literally or equivalently. In particular, individual features of the exemplary embodiments described below can also be used in other exemplary embodiments not shown below.

[0034] Several embodiments are described in the following figure description. Individual features of these embodiments can also be combined with embodiments not shown and are each suitable as advantageous embodiments of the objects described in one or more of the main and dependent claims.

[0035] The terms used below, such as "above," "below," "right," "left," "horizontal," "vertical," "inside," or "outside," refer to the orientation within the respective figures. Coordinate systems within the figures serve as further orientation aids. They transform in space when the spatial orientation changes.

[0036] In Fig. 1a Figure 1 shows a folding sliding door with several – here three – folding sliding panels 2a, b, c. More than three of these folding sliding panels are also possible.

[0037] The folding sliding door 1 is installed vertically, i.e., in an xy-plane according to the coordinate system in a typical installation position. Fig. 1a aligned.

[0038] The folding sliding sashes 2a, b, c each have a sash frame 3.

[0039] The folding sliding panels 2a, b, c are arranged such that when the folding sliding door 1 is opened, they are at an angle to each other and thus arranged in an overall accordion-like manner, as shown in Fig. 1a is shown.

[0040] A first folding sliding wing 2a is attached to a first vertical side by door hinges or hinges 10 (see Fig. 3 The first folding sliding door leaf 2a is rotatably hinged to the frame 4. The first folding sliding door leaf 2a is rotatably connected to a second folding sliding door leaf 2b on its second vertical side by hinges 10. The second folding sliding door leaf 2b can be attached to the frame 4 by a running and / or support device 20 (see Fig. 2 and Fig. 6 (Here, rollers engage in an undercut groove of the frame) and are slidably guided; furthermore, the second folding sliding sash 2b is rotatably connected to a third folding sliding sash 2c by hinges 10 on its second vertical side. One or more further folding sliding sashes could be provided in this manner (not shown here).

[0041] It may be provided that the second folding sliding wing 2a, b, c has a running and / or support device 20 at the top and / or bottom (not shown in detail here, see but Fig. 6 ), which is movable or slidable in the upper, horizontal section of the frame 4. Optionally, a lower guide can also be provided in another way, for example directly in the floor in the area of ​​a guide rail (not shown here).

[0042] The respective folding sliding wing 2a, b, c can have a surface element 5, which can be designed as insulating glazing and is inserted into the respective wing frame 3.

[0043] The respective sash frame 3 is preferably composed of profiles 31, which may be designed as composite profiles. Accordingly, the profiles 31 have at least two metal shells which are connected to each other by insulating webs 32. The sash frame 3 here consists of an upper, horizontal or parallel to the x-axis with respect to the coordinate system in Fig. 4a oder Fig. 4b aligned profile 31, two vertical, parallel aligned or parallel to the y-axis with respect to the coordinate system in Fig. 1a oder Fig. 1b Profiles 31 and a lower, horizontal or parallel to the x-axis with respect to the coordinate system in Fig. 4a oder Fig. 4b Profile 31 assembled.

[0044] Likewise, the frame 4 can be composed of profiles 41, which can also be designed as composite profiles. Accordingly, the profiles 41 have at least two metal shells connected to each other by insulating webs 42. The frame 4 here consists of an upper, horizontal or parallel to the x-axis with respect to the coordinate system in Fig. 1a oder Fig. 1b aligned profile 41, two vertical, parallel aligned or parallel to the y-axis with respect to the coordinate system in Fig. 1a oder Fig. 1b Profiles 41 and a lower, horizontal or parallel to the x-axis with respect to the coordinate system in Fig. 1a oder Fig. 1b Profile 41 is composed.

[0045] One of the folding sliding panels 2a, b, c of the folding sliding door 1 can be equipped with a handle 6 and a closing and / or locking device 7, with which the respective rotatably connected panel frames 3 can be closed or closed and locked to the frame 4. The handle 6 also serves to move the folding sliding panels 2a, b, c from a closed position to a folded-open position (see Fig. 1b ) and back.

[0046] In Fig. 1b The folding sliding door 1 is shown in a fully open state.

[0047] The folding sliding panels 2a, b, c are shown here folded together on one left side of the frame 4. The folding sliding panels 2a, b, c thus still occupy a portion of the opening (number of folding sliding panels 2a, b, c multiplied by the thickness of the respective frame 3).

[0048] Fig. 2 Figure 1 shows a spatial view of a section of two folding sliding doors 2a, b, each rotatably connected to the other by several hinges 10 – one of which is shown here – on their vertical profiles 31. On their respective horizontal upper frame sides, the folding sliding doors 2a, b each have a sealing profile 9. This has at least one outward-facing sealing lip or a web 18 for sealing contact with the frame 4.

[0049] Fig. 6 Figure 1 shows a sectional view of a horizontal frame section of the folding sliding door leaf 2a, b, c and the frame 4. A rebate space 8 between the sash frame 3 of the folding sliding door leaf 2a and the frame 4 is sealed with a sealing profile 9, which is attached to the upper horizontal profile of the sash frame 3 and which, in the closed state of the folding sliding door leaf 2a, rests against a counter-sealing surface of the frame 4.

[0050] The respective sealing profile 9 is therefore designed to create a rebate 8 between the respective sash frame 3 of the folding sliding sash 2a, b, c and the frame 4 relative to the surroundings at least vertically - i.e. parallel to the y-axis with respect to the coordinate system in Fig. 2 and Fig. 6 and horizontally at the top - that is, parallel to the y-axis in relation to the coordinate system in Fig. 2 and Fig. 6 to seal.

[0051] In a folding sliding door 1 with flush profiles 31, 41, a soft, large-volume sealing profile 9 is used to ensure water and airtightness, even with larger manufacturing tolerances, building settlement, or profile deformation due to weight and wind loads. At the same time, the sealing profile 9 must not be too stiff / hard to prevent excessive operating forces.

[0052] The sealing profile 9 is undeformed in Fig. 3 shown in section and in Fig. 6 The section shows the deformed state. In its undeformed state, the sealing profile can have a substantially U-shaped cross-section. The sealing profile 9 is positively attached to the upper surface of the upper horizontal profile of the sash frame 3 via a base web 11. For this purpose, the base web 11 can have a T-shaped slot-like projection 12 that can engage in a geometrically corresponding groove in the profile 31 of the sash frame 3.

[0053] One or more – in particular two – sealing lips can be attached to the outer end of the base web 11. These sealing lips are formed by an outer web 13 and an optional inner web 14 (the "outer" and "inner" refer to a wall separating the outside and inside). In their undeformed state, the inner web 14 and the outer web 13 each extend diagonally upwards from the base web 11 and outwards relative to the frame 4, or in the positive z-direction according to the coordinate system in Fig. 3 , as this in Fig. 3 is shown.

[0054] Both the inner web 14 and the outer web 13 have a kink 15, 16 in the undeformed state, through which the respective free ends or free sealing lips 17, 18 of both webs 13, 14 extend substantially vertically upwards or in the y-direction from the base web 11 with respect to the coordinate system in Fig. 3 are directed, as is the case in Fig. 3 is shown.

[0055] In the deformed state of the sealing profile 9 without support, which is in Fig. 6 As shown, the two webs 13, 14 are vertically upwards with respect to the base web 11, respectively, in the y-direction with respect to the coordinate system in Fig. 6 aligned and the respective free ends 17, 18 accordingly inclined upwards and inwards with respect to the wing frame 3 or in the negative z-direction with respect to the coordinate system in Fig. 6 This ensures that both webs 13, 14 of the sealing profile 9 can come into contact with a counter-sealing surface on the respective frame 3 when the respective sash frame 3 is closed, as shown in Fig. 4 or especially Fig. 6 The deformation of the sealing profile 9 exerts a certain sealing counter-pressure on the corresponding counter-sealing surface(s) on the respective frame 4.

[0056] Preferably, at least in the area of ​​locking elements 19 of the folding sliding leaves 2a, b, c, which are extended in the closed state of the folding sliding door 1 in order to fix the folding sliding leaves 4 to the frame 2 (see Fig. 6 ) according to the invention, an increased sealing counter-pressure is generated to compensate for play between the components, which is necessary to allow slight movement between the locking elements 19 - for example, locking rods and bolts as well as guides and guide rollers of the running and / or support device 20 and frame 4 (see Fig. 6 ) and simultaneously be able to compensate for manufacturing tolerances and layer thicknesses of surface protection coatings.

[0057] However, in the area of ​​the locking elements 19 of folding sliding doors 1, there is often a lack of sufficient sealing counter-pressure according to the state of the art, which can cause the locking elements 19 to produce an undesirable rattling noise.

[0058] It is therefore provided here that the sealing profile 9 - and in particular one of its sealing lips 18 - is supported and stabilized by a pressure element 100, especially in the area of ​​the locking elements 19.

[0059] This allows the sealing profile 9 to be specifically supported and stabilized at positions on the folding sliding door 1 where required. In this way, a higher sealing counter-pressure on the counter-sealing surface on the respective sash frame 3 can be generated in a simple and therefore advantageous manner.

[0060] The pressure element 100 preferably extends in direction X or horizontally only substantially over a section of the respective upper profile 31 of the sash frame 3 in one or more areas in direction X, in which one or more locking elements 19 are located in direction X, and not over its entire length in direction X (as shown in Fig. 6 (as shown). This refers to the closed state of the folding sliding door 1.

[0061] The pressure element may also be longer in direction X than the locking element 19 in this direction. However, it preferably extends no more than 250 mm in this direction, preferably a maximum of 150 mm.

[0062] It is also a preferred embodiment that in the X direction (relative to the closed state of the folding sliding door) the respective sealing profile 9 is only supported and stabilized by a respective pressure element 100 in front of and behind areas in which a respective folding sliding leaf 2a is articulated to the next folding sliding leaf 2b by one or more door hinges 10.

[0063] The pressure elements 100 can be, for example, approximately 50 to 250 mm long. And they can each be spaced a distance in the X-direction from the door hinges 10, for example up to 70 mm away.

[0064] The pressure element 100 can be attached to the sash frame 3 of the respective folding sliding sash 2a, b, c, as shown, for example, in Fig. 2a. It can also be provided that the respective pressure element 100 is attached to the upper, horizontal profile 31 of the sash frame 3 of the respective folding sliding sash 2a, b, c, as shown in Fig. 2 and in Fig. 6 as shown. Alternatively, it can also be provided that the pressure element 100 is attached under the lower, horizontal profile 31 of the sash frame 5 of the respective folding sliding sash 2a, b, c.

[0065] In Fig. 5a und Fig. 5b A first embodiment of the pressure element 100 is shown. The pressure element 100 can be made entirely or partially of plastic or metal, or of another material. This material is preferably stiffer than the sealing material from which the sealing profile is made.

[0066] The pressure element 100 can then have a fastening section 101 to fix it to the wing frame.

[0067] The fastening section 101 can have a base web 102 to which two clamping webs 103, 104, preferably designed symmetrically to each other, are integrally formed and which may be inclined downwards with respect to the base web 102.

[0068] The base web 102 can thus be horizontal, parallel to the insulating web 32 of the profile 31 of the respective wing frame 3 or in an xz-plane with respect to the coordinate system in Fig. 3 or in Fig. 5a be arranged and can be positioned along the upper horizontal or lower horizontal profile 31 of the respective wing frame 3 or parallel to the x-axis with respect to the coordinate system in Fig. 3 or Fig 5a extend.

[0069] The two clamping lugs 103, 104 can be designed to clamp the pressure element 100 in the area of ​​the insulating web 32 of the profile 31 of the respective sash frame 3, thereby creating a force-fit and form-fit connection between the respective frame profile 31, 41 and the pressure element 100. The form-fit is achieved, for example, by the fact that the two clamping lugs 103, 104 engage in a geometrically corresponding contour 33 in the respective insulating web 32 (see, e.g., Figure 1). Fig. 3 ).

[0070] With the base web 102, one or more can be positioned diagonally upwards in relation to the base web 102 and in relation to the respective wing frame 3 ( Fig. 2 ) outwards or in the positive z-direction with respect to the coordinate system in Fig. 2 The pointing side web(s) 105, 106 are joined in one piece.

[0071] Parallel to the base pier 102 and vertically upwards with respect to the base pier 102 or in the y-direction with respect to the coordinate system in Fig. 2 The fastening section 101 can have a support rib 107 spaced apart, to which the two side ribs 105, 106 can be integrally formed.

[0072] The base web 102, the two side webs 105, 106 and the support web 107 can thus form a closed, block-like profile with a parallelogram-like cross-sectional geometry, which is traversed by a hollow chamber 108.

[0073] The sealing-side side web 105 is extended in one piece to form a first pressure section 109, wherein the first pressure section 109 initially runs obliquely upwards with respect to the base web 102 and, after a bend 110, essentially vertically upwards or in the y-direction with respect to the coordinate system in Fig. 5a, 5b , 5cdirected in a second printing section 111 ends freely.

[0074] The second one, vertically upwards or in the y-direction with respect to the coordinate system in Fig. 4a und Fig. 4b The directed pressure section 111 supports the sealing profile 9 on its side facing away from the frame's counter-sealing surface in such a way that at least the inner web 14 extends Fig. 4a und Fig. 4b in the closed state of the respective sash frame 3 to the counter-sealing surface on the respective frame 4 in a vertical direction or in the y-direction with respect to the coordinate system in Fig. 4a und 4b stretch and accordingly form a flat surface without the bend 16.

[0075] According to this embodiment of the invention, the sealing profile is thus pressed against the counter-sealing surface on the frame 4 and is thereby stiffened by the second pressure section 111 of the pressure element. This also generates increased sealing counter-pressure, since when the respective sash frame 3 is closed, the free end or sealing lip 18 of the inner web 14 of the sealing profile 9 is compressed between the counter-sealing surface on the respective frame 4 and the second pressure section 111, and, with respect to the base web 102 of the pressure element 100, only moves vertically upwards or in the y-direction with respect to the coordinate system. Fig. 4a und Fig. 4b can avoid it.

[0076] It can optionally be provided that the pressure element 100 is spread open by at least one adjustable screw 112 such that the two clamping webs 103, 104 are pressed forcefully into a geometrically corresponding contour 33 in the respective insulating web 32, as shown in Fig. 5b is shown.

[0077] The pressure element 100 can preferably be made of a plastic material, but it can also be made of a metal, preferably a light metal.

[0078] In Fig. 5a An alternative method for spreading the pressure element 100 is shown. This differs from the illustration in Fig. 5b and in figures 2a, 3 , 4a , as well as 4b, the pressure element 100 is in Fig. 5b spread open by the screw 112, which is screwed into a slot 113 that is perpendicular to the drawing plane of the Figuren 3 , 4aas well as 4b or parallel to the x-axis with respect to the coordinate system in Fig. 5a in the base web 102 of the fastening section 101 of the pressure element 100.

[0079] In the Figuren 4b and 5c A second version of the pressure element 100 is shown in each case. This differs from the first version of the

[0080] Pressure element 100 according to the Figuren 4a , 5a, 5b The second pressure section 111 of the pressure element 100 has a slot 114 into which a screw 115 can be screwed, thereby widening the slot 114. This provides a simple way to adjust the sealing counter-pressure exerted by the sealing profile 9 on the respective counter-sealing surface on the frame 4, as shown in Fig. 4b is shown.

[0081] Analogous to the above description of the figures, the corresponding horizontal rebate space below the sash frames can be sealed with a sealing profile 9 and, if necessary, a pressure element 100 (not shown here), as described above. The aforementioned features are then fulfilled analogously below the sash frame. Bezugszeichenliste
