Description

TECHNICAL AREA

[0001] The present invention relates to a sliding door seal for sealing a door gap of a sliding door, in particular an upper door gap. STATE OF THE ART

[0002] Due to its suspension and movement unit, sealing the upper gap of the sliding door is difficult.

[0003] DE 2 206 186 A discloses a seal for sliding doors designed to reduce friction by preventing the sealing elements from sliding against each other longitudinally during opening and closing of the door. For this purpose, the movable door leaf is moved in three orthogonal directions when closing. Such doors are no longer considered state-of-the-art.

[0004] EP 1 860 272 A2 proposes arranging a seal with a movable sealing strip in the upper area of ​​a vertical frame member to seal the frame horizontally against a door leaf of the sliding door sash. EP 2 366 857 A2 proposes arranging a sealing rail with a movable sealing strip on the carriage of the sliding door sash so that the sealing strip also moves horizontally and seals against the door frame.

[0005] EP 3 825 503 A1 shows a sliding door with a sealing strip that moves automatically when the door leaf is closed, which is arranged on an upper end face of the door leaf and seals vertically upwards.

[0006] DE 20 2007 006 127 U1 describes a sliding element of a room divider with a strip-shaped flexible seal arranged on the underside of a sliding body, which is inserted in a groove of a rail. An upper seal is not shown.

[0007] DE 2 302 234 A shows a sealing device for foldable partition walls in the form of flexible profile strips arranged on the movable wall body. PRESENTATION OF THE INVENTION

[0008] It is an object of the invention to create a sliding door seal which is suitable for sealing a door gap, in particular an upper door gap, and which can be used in a variety of ways.

[0009] This task is solved by a sliding door seal with the features according to claim 1.

[0010] The sliding door seal according to the invention comprises a first sealing part for attachment to a stationary element of a sliding door and a second sealing part for arrangement on a movable door leaf of the sliding door. The first and second sealing parts run parallel to each other and define a longitudinal direction. Together, the first and second sealing parts form a barrier to close the door gap between the stationary element and the movable door leaf. The barrier defines a transverse direction that runs perpendicular to the longitudinal direction. The barrier has at least one self-aligning or self-compensating element that is movably guided in a bearing.

[0011] In this text, the term "self-aligning" is used synonymously with "self-balancing." A self-aligning element, thanks to its flexibility, adapts to external conditions and assumes an optimal position according to the circumstances.

[0012] The transverse direction runs along the surface of the barrier with which the barrier closes the gap. Due to the arrangement, the second sealing part is longitudinally displaceable relative to the first sealing part.

[0013] Thanks to its self-aligning element, the sliding door seal can be constructed with simple components and offers a high degree of design flexibility, without the need for seals with movable sealing strips, i.e., so-called drop seals. The sliding door seal automatically adapts to the specific conditions on site.

[0014] The use of a barrier with at least one self-aligning element avoids unwanted noise when opening and closing the sliding door and offers optimal light protection.

[0015] The sliding door seal according to the invention requires no release mechanism because the barrier forms the necessary sealing surface in every position of the movable door leaf. Nevertheless, the seal is not static but adapts dynamically thanks to at least one self-aligning element. The sliding door seal according to the invention thus combines the advantages of an automatic drop seal with those of static seals, without inheriting their disadvantages.

[0016] The inventive design of the sliding door seal allows for versatile use, particularly in the upper area of ​​the sliding door, including the track and wheel. The sliding door seal does not need to be adapted to a specific sliding door system design; instead, the same design can be used in different systems. The basic elements of the sliding door seal can be supplemented with various components, enabling a multitude of installation options. This increases flexibility and reduces manufacturing costs. In particular, it can also be used in sliding doors with soft-close mechanisms.

[0017] Furthermore, already installed sliding doors can also be retrofitted with such a sliding door seal.

[0018] The sliding door seal is extremely space-saving and can also be used for glass doors.

[0019] Thanks to the barrier's self-leveling and self-aligning properties, manufacturing and installation are simplified. Furthermore, individual elements of the seal can be replaced more easily.

[0020] The barrier with the self-aligning element minimizes the forces required when moving the door leaf, thus increasing user comfort.

[0021] The sliding door seal can be used to seal the upper door gap. Depending on its position in the sliding door, it can seal the upper edge of the door leaf against a stationary component located above this edge, or it can seal a side edge of the door leaf against a stationary element located to the side. If the longitudinal direction of the installed sliding door seal is horizontal, it can be used to seal either the upper or lower door gap. If the longitudinal direction is vertical when installed, it can be used to seal a vertical door gap.

[0022] If the sliding door seal is used to seal the lower door gap, it can be arranged without barriers.

[0023] Preferably, the self-aligning element is at least one sealing strip running parallel to the longitudinal direction. Preferably, a first and a second sealing strip are provided, both running parallel to the longitudinal direction, with at least one of them being a self-aligning element.

[0024] Preferably, the first sealing strip or the second sealing strip is mounted in a floating manner within the other sealing strip, either parallel to the transverse direction and / or parallel to the longitudinal direction. This floating mounting provides optimal self-alignment and self-compensation.

[0025] A floating bearing has the advantage that, when the sliding door seal is installed, the relative position of the two sealing strips to each other in the vertical and / or horizontal direction adjusts automatically, even if, for example, the floor height of the door leaf is readjusted.

[0026] The advantages already mentioned apply particularly to embodiments with floating bearings and especially to embodiments in which the sealing strips are floating in the direction parallel to the transverse direction.

[0027] Preferably, the first and second sealing strips are jointly part of the second sealing element, which can be attached to the sliding door leaf, or they are jointly part of the first sealing element, which is attached to the stationary sliding door element. Preferably, in these cases, the two sealing strips are fixedly connected to each other longitudinally, but preferably also floatingly connected to each other in the direction parallel to the transverse direction.

[0028] The sealing strips are preferably longitudinal profiles of equal length. They extend approximately across the entire width of the sliding door leaf when they are part of the movable sealing element, and they are approximately the same length as the track when they are part of the fixed sealing element.

[0029] In other embodiments, one of the two sealing strips is part of the first sealing part, and the other is part of the second sealing part. In this case, the two sealing strips are longitudinally displaceable relative to each other. Preferably, however, they are still mounted in a floating manner relative to each other. The sealing strip arranged on the first sealing part preferably has a length corresponding to the guide rail. The other sealing strip preferably has a length corresponding to the width of the door leaf.

[0030] Preferably, the first or second sealing strip has a longitudinally extending receiving groove with a U-shaped or C-shaped cross-section, and the other sealing strip has a longitudinally extending counterpart with a matching cross-section. The counterpart is preferably mounted transversely, and thus perpendicular to the longitudinal direction, in a floating manner. Other types of floating mounting are possible. Likewise, other cross-sections of the grooves and the counterparts are possible. The groove and the counterpart each preferably extend over the entire length of the respective sealing strip. Preferably, the groove is open on both end faces.

[0031] In some embodiments, the first sealing strip and / or the second sealing strip is flexible or soft. In other embodiments, one sealing strip is soft or flexible and the other is stiff or rigid. Preferably, however, both sealing strips are stiff or rigid. "Rigid" in this text is understood as not movable and not elastic, "stiff" as not soft, not movable, but with very little flexibility.

[0032] Preferably, at least one of the two sealing strips is pivotable about an axis running parallel to the longitudinal direction. This increases ease of assembly thanks to further self-compensation and self-alignment, reduces wear from rubbing parts, and for the same reason reduces operating forces and noise.

[0033] In preferred embodiments, at least one of the sealing strips is pivotable about an axis running parallel to the longitudinal direction. This increases the self-compensation or self-alignment of the individual elements. Installation tolerances are increased.

[0034] In particularly preferred embodiments, the degrees of freedom of the individual components and thus the self-compensation or self-alignment of the sliding door seal are maximized by making the first sealing strip and the second sealing strip pivotable about an axis running parallel to the longitudinal direction.

[0035] The pivotability can be achieved in various ways. Preferably, it is guided. Alternatively, it can be achieved, for example, via a spring-loaded or flexible connection. In preferred embodiments, the at least one pivotable sealing strip has a pivoting body extending over its entire length, the pivoting body preferably having a round cross-section. Preferably, the pivoting body is hollow and has a groove open perpendicular to the longitudinal direction and parallel to the transverse direction. The pivoting body thus preferably has the form of a hollow profile, which is preferably slotted in the longitudinal direction. The pivoting body is preferably integrally connected to a sealing body. The sealing body of one sealing strip is preferably floatingly mounted in the sealing body of the other sealing strip.

[0036] In some embodiments, the first and second sealing strips are attached directly to the fixed and sliding parts of the sliding door, for example by means of screws, an adhesive bond, or by hinges. In other embodiments, one sealing strip is directly connected and the other sealing strip is directly connected.

[0037] Preferably, the first sealing element has a first receiving element that is either part of the sliding door or serves for attachment to the fixed element of the sliding door. The first sealing strip is held in the first receiving element. Alternatively or additionally, the second sealing element has a second receiving element that is either part of the sliding door or serves for attachment to the sliding door leaf. The second sealing strip is held in the second receiving element. This simplifies installation, and the sliding door seal can be installed without modifying the sliding door, and can also be retrofitted.

[0038] As mentioned, the first and second mounting parts can be separate components that can be attached to the fixed or sliding part of the sliding door, respectively. In other embodiments, the two mounting parts are an integral part of the sliding door, for example, by being designed accordingly in the track, door frame, a wall, a cover, or a wall adapter of the sliding door.

[0039] The receiving elements are preferably longitudinal profiles, with the stationary receiving element preferably being longer than the movable receiving element. Preferably, it is at least approximately twice as long, so that movement is possible over the entire sliding path of the sliding door.

[0040] In some embodiments, the sealing strips are rigidly connected to the receiving parts. Preferably, however, the first sealing strip is positionally adjustable relative to the first receiving part and / or the second sealing strip is positionally adjustable relative to the second receiving part. This provides further degrees of freedom for adapting the sealing strips to the local conditions.

[0041] Preferably, the first sealing strip and / or the second sealing strip is pivotably mounted in the first or second receiving part about an axis parallel to the longitudinal direction. This pivotability, in combination with the floating mounting, allows for optimal adaptation to local conditions and maximizes the self-leveling and self-alignment of the sealing device.

[0042] The connection between the sealing strip and the receiving part can be achieved in various ways. In preferred embodiments, the first receiving part has a first connecting body with a first bearing groove for receiving the first sealing strip, and / or the second receiving part has a second connecting body with a second bearing groove for receiving the second sealing strip. Preferably, the first or second pivoting body is arranged in the first or second bearing groove, respectively. A first and / or second bearing groove with an approximately circular cross-section is preferred, which allows for optimal pivotability of the connection. Preferably, one of the two sealing strips is longitudinally displaceable within its receiving part, while the other is not. Preferably, however, both are pivotable within their receiving parts.

[0043] The attachment of the first and / or second mounting part to the sliding door, if they are not already an integral part of it, can be done in various ways. For example, they can be glued or screwed on. Preferably, the mounting parts have a base plate for attachment to one of the aforementioned components of the sliding door to facilitate the attachment.

[0044] The sealing strips are preferably made of plastic, aluminum, or an elastomer. Depending on the design, they may have a coating, such as flocking or another coating, that improves their sliding properties. However, they can also be uncoated.

[0045] The mounting parts are preferably made of aluminum or plastic.

[0046] Preferably, the sealing strips and / or the receiving parts are each formed in one piece.

[0047] A sliding door arrangement according to the invention comprises a sliding door and a sliding door seal according to the invention, wherein the first sealing strip of the sliding door seal is attached directly or indirectly to a running rail, a door frame, a wall adapter, a cover or a building wall of the sliding door.

[0048] Further embodiments are specified in the dependent claims. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF PREFERRED EXECUTION FORMS

[0050] The Figures 1 and 2Figure 1 shows an example of a sliding door with which the sliding door seals according to the invention can be used. In a door frame R, a door leaf F is held slidably in an upper track S relative to a stationary part of the sliding door. In this example, the stationary part is formed by the building wall or the frame R. In other embodiments, particularly with glass doors, this is a separate component. The floor is in the Figures 1 and 2 schematically represented and bears the reference symbol B.

[0051] In the Figures 1 to 7A first embodiment of the sliding door seal according to the invention, mounted in a sliding door, is shown. The door leaf F is slidably mounted in the track S via at least one connecting part V and at least one running wheel W, which together form a carriage. The track S has corresponding grooves for receiving and guiding the running wheel V, W. The connecting part V forms a suspension for the door leaf and preferably has a spindle for adjusting the floor height, i.e., the distance of the door leaf from the floor.

[0052] The sliding door seal comprises a first receiving part 1, a first sealing strip 2, a second sealing strip 3, and a second receiving part 4. The first receiving part 1 is attached to the fixed part of the sliding door, here the track S. The second receiving part 2 is attached to the movable part, i.e., the door leaf F. Both receiving parts 1 and 4 have, as shown in Figure 5It is recognizable that a first or second base plate 10, 40 is present.

[0053] The first receiving part 1 has a first base plate 10, which preferably has a flat surface for attachment to the stationary part of the sliding door. It also has a first connecting body 11 integrally molded onto the first base plate 10, which forms a first bearing groove 12. The first connecting body 11 is designed as a slotted hollow tube. The first bearing groove 12 has a circular cross-section. In this example, the first bearing groove 12 is located on the side facing away from the surface of the first base plate 10 and allows access perpendicular to the surface of the first base plate 10. Therefore, in the assembled state, it is open downwards, and the base plate 10 is attached to the downward-facing side of the stationary part.

[0054] The second receiving part 4 has a second base plate 40, which preferably has a flat surface for attachment to the stationary part of the sliding door. It also has a second connecting body 41 integrally molded onto the second base plate 40, which forms a second bearing groove 42. The second connecting body 41 is designed as a slotted hollow tube. The second bearing groove 42 has a round cross-section. In this example, the second bearing groove 42 is located on the side facing away from the surface of the second base plate 40 and allows access parallel to the surface of the second base plate 40. Therefore, in the assembled state, it is open at the top, and the second base plate 40 is attached to a vertical side of the door leaf F.

[0055] The base plates 10, 40 and the connecting bodies 11, 41 extend over the entire length of the respective receiving parts 1, 4 which are designed as longitudinal profile strips.

[0056] The first sealing strip 2 is held in the first receiving part 1. It is, as in Figure 3 The second sealing strip 3 is visibly held pivotably relative to the second receiving part 4, preferably mounted. The second sealing strip 3 is held in the second receiving part 4. It is also held pivotably relative to this, preferably mounted.

[0057] The first sealing strip 2 has a first pivoting body 21. The first pivoting body 21 can be designed as a solid body or, as in this example, as a hollow tube with a round cross-section. The first pivoting body 21 has a first pivoting body groove 22. The first pivoting body groove 22 is preferably open at the top when the seal is installed. The first pivoting body 21 is received in the first bearing groove 12. The slotted design of the two engaging bodies 11 and 21 simplifies assembly.

[0058] The first sealing strip 2 is arranged in the first receiving part 1 so as to be slidable in the longitudinal direction L of the sliding door seal. It is therefore pivotable and slidable relative to the first sealing strip 1.

[0059] The first sealing strip 2 further comprises a first sealing body 20, which is preferably integrally formed on the first pivoting body 21. The first sealing body 20 has a U-shaped cross-section with two parallel side walls that form a receiving groove 200 between them. The receiving groove 200 is open on the side opposite the pivoting body 21. Thus, in the assembled state of the seal, it is open downwards.

[0060] The second sealing strip 3 has a second pivoting body 31. The second pivoting body 31 can be designed as a solid body or, as in this example, as a hollow tube with a round cross-section. The second pivoting body 31 has a second pivoting body groove 32. The second pivoting body groove 32 is preferably open downwards when the seal is installed. The second pivoting body 31 is received in the second bearing groove 42. The slotted design of the two engaging bodies 41, 31 simplifies assembly.

[0061] The second sealing strip 3 is fixed in the second receiving part 4 along the longitudinal direction L of the sliding door seal. It is only pivotable. This can be achieved, for example, by appropriately shaping the pivot groove and the pivot body. In the illustrated embodiment, the covers 5 described below, which are fixed with caps 6 that can be inserted into the groove or with screws, serve as stops on both sides. The stops can also be designed in other ways. The stops have the advantage that the second sealing strip 3 is easier to install, as it can be inserted into the receiving part 4. In addition, both receiving parts 1, 4 can be designed identically if they can be manufactured as continuous lengths and optionally combined with either of the two sealing strips. This increases the number of possible installation variants.

[0062] The second sealing strip 3 further comprises a second sealing element 30, which is preferably integrally formed on the second pivoting element 31. This second sealing element 30 is preferably designed as a solid body. It preferably has a rectangular cross-section. At least in the assembled state, it is inserted into the receiving groove 200 of the first sealing strip 2 and is floatingly mounted there.

[0063] The second sealing strip 3, the second receiving part 4 and the door leaf F connected to it can thus be moved together with the first sealing strip 2 relative to the fixedly mounted first receiving element 1 and thus to the running rail S.

[0064] A barrier is formed between the first and second receiving parts 1, 4, in particular by the first and second sealing strips 2, 3, which closes the door gap. This barrier defines a transverse direction Q that runs perpendicular to the longitudinal direction L. Furthermore, it extends across the surface of the barrier, in particular the sealing strips 2, 3, which closes the door gap.

[0065] As in Figure 6 As can be seen, the first receiving part 1, and thus the stationary first sealing part, preferably extends over the entire length of the track S. The sliding second sealing part, formed by the first sealing strip 2, the second sealing strip 3, and the second receiving part 4, extends over the width of the door leaf, but terminates at least on one end face at a distance from it. This allows the combination of this horizontal seal with a vertical seal, as shown below.

[0066] As in Figure 4 As can be seen, the sliding door seal further comprises two covers 5 and two caps 6. The covers 5 cover the two end faces of the first and second sealing strips 2, 3 and thus also the first and second bearing grooves 12, 42. In some embodiments, only at least one cap 6 is present, but no cover 5. The at least one cap 6, which is preferably made of a flexible material, serves as a seal against a preferably flexible, vertical sealing strip 7. It is inserted through a through-opening 50 in the cover. If it also penetrates the second bearing groove 42, it simultaneously serves to fasten the cover. If it is flat or recessed relative to the cover 5, it serves only for fastening. This is shown in Figure 7 clearly visible.

[0067] In Figure 8A further embodiment of the sliding door seal according to the invention is shown. The stationary first receiving part 1 is designed identically to the second receiving part 4 described above. It can therefore be used for attachment to a stationary vertical surface, here the door frame R. The movable second receiving part 4 is designed identically to the one already described. However, it is now attached to the upper horizontal surface of the sliding door leaf F. The first and second sealing strips 2, 3 remain unchanged. This design and arrangement still seals the upper gap between the door leaf F and the track S, but in a horizontal direction.

[0068] As can be seen by comparing the embodiments according to the Figures 3 to 7 and 8As can be seen, different arrangements can be achieved with the same components. Depending on the embodiment and design of the first and second bearing grooves 12, 42, the first or the second sealing strip 2, 3 is slidably mounted in the longitudinal direction of the strips in the associated bearing groove 12, 42, while the other sealing strip 2, 3 is fixedly mounted in the corresponding bearing groove 12, 42 in the longitudinal direction. In other embodiments, the first sealing strip 2 extends over the entire length of the guide rail and is fixedly connected to the first receiving part 1. The second sealing strip 3 is guided and slidably in the longitudinal direction relative to the first sealing strip 2, and preferably remains floating in the transverse direction Q to compensate for floor adjustments of the door leaf.

[0069] In Figure 9Two sliding door seals are visible, sharing a common second receiving part 4. The second receiving part is designed as a U-profile rail, which is arranged in an upper groove of the door leaf F. The U-profile rail forms a large U-shaped groove for attaching the suspension V and has a smaller U-shaped groove at each of the free ends of its two legs, which is also open at the top.

[0070] These two smaller grooves form the second bearing grooves 42 for receiving the second sealing strip 3. In this example, the second sealing strip 3 is provided with a U-shaped receiving groove 300, and the sealing body 20 of the first sealing strip 2 is a T-nut with a rectangular cross-section.

[0071] The first receiving part 1 is integrally formed with a fixed part of the sliding door. In this case, it is a cover E, which is detachably connected to the running rail S.

[0072] Depending on the design of the bearing grooves 12, 42 of the two receiving parts 1, 4, one or the other of the two sealing strips 2, 3 is mounted to be displaceable in the longitudinal direction or to be fixed in the longitudinal direction. Preferably, however, at least one sealing strip 2, 3, and preferably both sealing strips 2, 3, are mounted to be pivotable.

[0073] In Figure 10 Another embodiment is shown. The guide rail S is connected to a cover E on one longitudinal side, and a wall adapter A is present on the other longitudinal side. The wall adapter has the first receiving part 1 as an integral component. The second receiving part 4 is in turn designed as a smaller groove of an insert element that is inserted into an upper groove of the door leaf F.

[0074] In Figure 11 The guide rail S itself rests against the door frame R. The first receiving part 1 is designed identically to the first embodiment according to the Figures 3 to 7The second receiving part 4 has an angled base plate 40, so that it can be attached to an edge of the door leaf F on two sides of the door leaf F.

[0075] By comparing the previous examples with Figure 11 It is evident that the floating mounting of the first and second sealing strips 2 and 3 allows for a high degree of adaptability of the sliding door seal in the direction perpendicular to its longitudinal direction and parallel to its transverse direction, thus permitting increased adaptability in the horizontal or vertical direction of the sliding door, depending on the installation method. Furthermore, if one or two additional pivot points are present, a very high degree of adaptability and flexibility is achieved.

[0076] The sliding door seal according to the invention can be used in a variety of ways and enables frictionless and quiet operation of the sliding door seal. REFERENCE MARK LIST
