Description
[0001] Sliding door with pivoting sealing strip
[0002] Background of the invention
[0003] The invention relates to a sliding door comprising a frame and a leaf, wherein the leaf is movable in a closed position perpendicular to its leaf plane in order to place the leaf against the frame or to set it aside from the frame, and wherein the leaf set aside from the frame is displaceable in the leaf plane in order to open or close a door opening.
[0004] Such a sliding door is known, for example, from EP 2 829 679 Bl or from the brochure "Roto Patio Inowa - The smart fitting for highly sealed sliding systems" downloaded from https: / / media.ftt.roto- frank.com / # / reader / 2e064a3c-8013-39c7-c9d3-2c65becl5d79.pdf on
[0005] July 11, 2023. To ensure a continuous seal, the threshold of this sliding door protrudes slightly above the level of a pavement.
[0006] In order to achieve sufficient sealing of a door leaf against a threshold, various solutions have been proposed for pivoting doors (with a leaf hinged on one side and pivoting around a vertical axis).
[0007] For example, DE 10 2017 101 557 A1 describes a door threshold with a door threshold housing which reliably assumes the function of a high door threshold when a door leaf is in the closed position and which is completely barrier-free when a door is open, without requiring an external energy supply for its change of state.This is achieved in that the door threshold has a ground level and a raised level and it has a movement mechanism that is driven by a toothed rack that can be moved in the closing direction (perpendicular to a frame) of a door. The rack is connected to a trigger that projects above the ground level and forms a functional unit with the door shortly before the door is fully closed until it is closed. An eccentric shaft can be rotated with the toothed rack. A pinion and a lifting cam are arranged on the shaft and rest beneath the door threshold. The door threshold is hinged to the door threshold housing so that it can pivot about a pivot joint. The door threshold is therefore raised when the door leaf is moved towards the door threshold. The door leaf can strike a front stop surface of the door threshold.
[0008] A similar door sill is known from DE 10 2017 101 559 A1, in which a drive for a camshaft for raising the door sill comprises a deflectable thrust element. The thrust element can consist of a guided spring steel strip or a steel core guided in a flexible outer cable, or even a guided thrust link chain.
[0009] Another similar threshold for a patio or balcony door is known from DE 10 2006 029 353 B3. In this threshold, an actuator for raising a partially retractable strip is mounted in the door sill in the closing direction (perpendicular to the frame).
[0010] DE 1 509 280 A describes a door seal for a hinged or sliding door, in which a sealing strip embedded in the floor is pushed upwards when the door is closed. A double-armed lever lifts the sealing strip vertically. The lever is angled at its pivot point. One of the arms of the lever is operatively connected to the sealing strip, and the other short arm of the lever is operatively connected to the narrow surface of the door facing the hinges.
[0011] A similar lifting threshold is known from DE 10 2017 101 555 A1. A pivoting lever for raising a door threshold is pivoted about a vertical pivot axis and acts on the door threshold via a cam mechanism, so that the door threshold strikes the underside of the door from below when the door is closed.
[0012] Other door thresholds with sealing strips that can be moved translationally in the vertical direction are known from US 7,028,740 B2, US 2011 / 0265386 Al or EP3458 669 Bl.
[0013] It is an object of the invention to enable effective sealing of a sliding door of the type mentioned above with a barrier-free or at least low-barrier threshold. Description of the invention
[0014] This object is achieved according to the invention by a sliding door according to claim 1, a threshold arrangement according to claim 21 and a frame according to claim 22. Advantageous embodiments are specified in the subclaims and the description.
[0015] According to the invention, a sliding door is provided. The sliding door has a frame and a leaf. In a closed position, the leaf is movable perpendicular to its leaf plane in order to place the leaf against the frame or to set it aside from the frame. The movement for placing the leaf against the frame and setting the leaf apart from the frame always occurs strictly perpendicular to the leaf plane. The movement for placing or setting down the leaf is in particular a purely translational movement. In the closed position, the leaf completely covers the door opening. The closed position can also be referred to as a closed position or an end position of the leaf. The leaf, set aside from the frame, is movable in the leaf plane in order to open or close a door opening.
[0016] The threshold can have a track along which the sash can be moved when the sash is parked on the frame. The sash can have a carriage for moving the sash along the track. Preferably, the carriage is coupled to a handle, and actuation of the handle causes the sash to move perpendicular to the track. The carriage can have a suitable mechanism for this purpose, for example, with a transverse guide. The movement triggered by the carriage when the handle is actuated generally has no component along the track; it therefore occurs strictly perpendicular to the track or sash plane.
[0017] The frame has a sill on which a sealing strip is mounted, which can pivot between a lowered and an upright position. A pivot axis of the sealing strip runs parallel to the sash plane. The pivot axis thus extends parallel to the sliding direction of the sash. The pivot axis can be an imaginary or physical axis of the sealing strip's pivoting movement. A pivotable sealing strip is easily actuated to move it between the lowered and upright positions, is particularly resilient, and requires only a small installation height below its top surface, for example, for fastening or supporting the sealing strip or a mechanism for raising the sealing strip.
[0018] In the lowered position, the sealing strip preferably sits flush with the top side of the threshold, particularly a tread plate of the threshold. In the lowered position, which occurs when the sash is open, the sealing strip can be easily crossed, particularly with walkers or wheelchairs, or stepped over without the risk of getting stuck. The tread plate can provide a flush (level) connection between the threshold and a pavement. It is understood that the tread plate can be made of sheet metal, particularly metallic, or another suitable material, e.g., plastic. In particular, the tread plate can be manufactured as an extruded profile or an injection-molded part.
[0019] In the raised position, the sealing strip protrudes beyond the upper side of the threshold, particularly the threshold's tread plate. The raised sealing strip enables effective sealing of the sliding door.
[0020] When pressed against the frame, the sash touches the raised sealing strip with one front side (facing the frame). This reliably creates a seal in the lower area of the sash. The front side typically corresponds to an outer side of the sash. When pressed against the frame, the sash preferably rests all the way around a sealing arrangement of the frame. In particular, the frame can have a sealing arrangement running continuously in one plane for contact with the sash, with the sealing strip being part of the all-round sealing arrangement. This creates an all-round seal between the sash and the frame. The sealing in one plane on the front side of the sash prevents potentially leaky points.In addition, sealing in a common plane simplifies the design of the sealing arrangement for reliable sealing regardless of manufacturing and assembly tolerances and any wear.
[0021] For the description of the present invention, direction or position information such as above or below refers to the installed state of the sliding door.
[0022] The sliding door has an actuating element for raising the sealing strip, which is designed to raise the sealing strip from the lowered position when the sash (which has been set aside from the frame) is moved into the closed position. The actuating element thus raises the sealing strip as soon as the sash is moved parallel to the sash plane into the closed position. In other words, the sealing strip is at least partially raised as the sash is moved in the sliding direction parallel to the threshold (along a track). This allows the sealing strip to make contact with the front of the frame when the sash is placed against the frame, without the risk of the sealing strip getting caught on the sash.
[0023] The actuating element typically interacts with the leaf, with the leaf coming into contact with the actuating element during the final part of its movement—approximately the last 0.5 to 5 centimeters—as it moves into the locked position. In particular, it can be provided that, when the leaf is moved, a vertical leaf beam with a narrow side oriented perpendicular to the leaf plane or a frame-side edge of this narrow side engages the actuating element. This prevents the actuating element from protruding into the door opening.
[0024] The actuating element is preferably rotatable about a rotation axis. This enables a stable design and can help keep manufacturing costs to a minimum. The actuating element and the sealing strip are preferably configured such that the sealing strip moves into the lowered position under the effect of gravity when the leaf is pushed from the closed position to release the door opening. Alternatively or additionally, a spring element can be provided to move the sealing strip into the lowered position.
[0025] In an advantageous embodiment, the actuating element is configured to move the sealing strip completely into the raised position when the sash is moved into the closed position. This can simplify the interaction of the sash with the actuating element.
[0026] In an alternative, equally advantageous embodiment, the actuating element is designed to raise the sealing strip into an intermediate position when the sash is moved into the closed position. When the sash is placed against the frame, the sealing strip is then moved from the intermediate position into the raised position. The further movement of the sealing strip from the intermediate position to the raised position can be effected by the actuating element and / or directly by the sash. In the intermediate position, the sealing strip is raised or raised less far than in the raised position. The two-stage lifting allows a comparatively large opening movement of the sealing strip to be achieved.
[0027] In an advantageous embodiment, a rotation axis of the actuating element is aligned perpendicular to the pivot axis of the sealing strip. The rotation axis typically runs perpendicular to the sash plane. This can simplify the design of the actuating element. This embodiment is particularly suitable if the sealing strip is to be fully extended when the sash is moved into the closed position.
[0028] In a further development of this embodiment, the actuating element is a pivotally mounted lever with two legs, with a first leg engaging underneath the sealing strip and a second leg projecting upwards, so that it is deflected by the sash when the sash is moved into the closed position. The kinematic transmission of the actuating element can be adjusted by varying the leg lengths in order to achieve complete opening of the sealing strip with a short displacement of the sash.
[0029] The angle between the legs can be at least 60°, preferably at least 70°, and / or at most 85°, preferably at most 80°. The lever can, in particular, be configured to rotate by 15°+ / -5° to move the sealing strip from the lowered to the raised position.
[0030] In an alternative, equally advantageous embodiment, a rotational axis of the actuating element corresponds to the pivot axis of the sealing strip, preferably with the actuating element being fixed to the sealing strip. This can reduce the complexity of the mechanism; in particular, a separate mounting of the actuating element can be omitted. This embodiment is particularly suitable if the sealing strip is to be initially raised to an intermediate position when the sash is moved into the closed position and then fully raised when the sash is brought into contact with the frame.
[0031] In a further development of this embodiment, the actuating element has a contact surface for the sash that is inclined, in particular curved, relative to the rotation axis. When the parked sash is moved into the closed position, the inclination or curvature of the contact surface can influence the kinematic translation of the actuating element. Preferably, the contact surface projects horizontally beyond the sealing strip when the sealing strip is in the lowered position. This allows the sash to engage the actuating element with an edge of a vertical sash spar when moved into the closed position without coming into contact with the sealing strip.In a particularly preferred embodiment, the sealing strip has a sealing profile with two end regions, wherein a first end region of the sealing profile forms at least one sealing lip for contact with the sash and a second end region of the sealing profile is fixed to the sill, in particular to a tread plate of the sill, and wherein a deformation section is formed in the sealing profile between the second end region and the first end region, wherein the deformation section defines the pivot axis. In other words, the deformation section acts as a film hinge. This enables a particularly simple and robust design of the sill arrangement. In addition, the connection of the sealing profile to the sill prevents a gap from forming between the sealing strip and the sill, in particular between the sealing strip and the tread plate.Furthermore, the deformed section of the sealing profile allows the sealing strip to pivot with virtually no wear. A cavity can be provided within the sealing lip; such a sealing lip can also be referred to as a balloon seal.
[0032] In an advantageous development of this embodiment, the sealing strip has a stiffening element for the sealing profile, which is arranged between the deformation section and the sealing lip. On the one hand, the stiffening element increases the stability of the sealing strip when subjected to loads caused by walking or driving on it. On the other hand, the stiffening of the sealing profile can allow a greater contact pressure on the sash, which improves the sealing effect. The sealing profile can be injection-molded or cast onto the stiffening element. This allows for efficient production of the sealing strip. In particular, the stiffening element can be overmolded or cast with the sealing profile. In other words, the stiffening element can be embedded in the sealing profile. This creates a particularly permanent connection between the stiffening element and the sealing profile.
[0033] In an alternative, equally advantageous embodiment, the sealing strip has a support profile and a sealing element held on the support profile, wherein the support profile is pivotally mounted on the sleeper. This can simplify the installation of the sealing strip on the sleeper. In addition, the defined mounting of the support profile on the sleeper allows the mobility of the sealing strip to be determined particularly precisely. In particular, the support profile can have a spherical groove extending along the pivot axis, into which a hinge projection of the sleeper engages. The spherical groove typically has a rounded, in particular circular, cross-section. The rounded shape of the spherical groove can facilitate the hinge-like pivoting of the sealing strip relative to the sleeper. The hinge projection preferably extends over at least 70%, in particular at least 85%, of the length along the spherical groove.The joint projection can consist of several sections.
[0034] In an advantageous further development of this embodiment, the support profile has a stop section for contact with the threshold when the sealing strip is in the raised position. This stop section prevents the sealing strip from accidentally rising beyond its raised position and thus ensures a sufficiently high contact force of the sealing strip against the front of the sash.
[0035] The frame can have a vertical member and a corner piece arranged in the corner area of the vertical member and the sill, against which the sash rests when positioned against the frame. The corner piece thus contributes to sealing the sash against the frame in the corner area. The corner piece can be part of a sealing arrangement that runs continuously in one plane. In particular, the corner piece can be compressed when the sash is placed against the frame.
[0036] When the sash is positioned against the frame, the actuating element is preferably housed in the corner piece. This embodiment is particularly suitable for an actuating element that can be positioned about a rotation axis running parallel to or coinciding with the pivot axis. The actuating element then does not impair the sealing effect in the corner area. The actuating element preferably rests against the corner piece when the sealing strip is in the positioned position. The corner piece thus acts as a stop for the actuating element. This prevents the sealing strip from unintentionally extending beyond its positioned position. This ensures a sufficiently large contact force of the sealing strip against the front of the sash.
[0037] The sealing strip can have one sealing lip for contact with the front of the sash and another sealing lip for contact with the underside of the sash. This allows for particularly effective sealing. A free end of a sealing profile or sealing element of the sealing strip facing the sash can be U-shaped, so that the two sealing lips are each formed by one of the legs of the U-shaped end.
[0038] An additional seal can be arranged on the underside of the sash, with a vertical sealing surface formed within the sill for the additional seal to engage when the sash is in contact with the frame. This can further improve the seal between the sash and the frame. The additional seal is typically not located in the plane of a circumferential sealing arrangement for the front-facing contact with the sash. The vertical sealing surface within the sill is generally located below the top surface of the sill.
[0039] The scope of the present invention further includes a threshold assembly for a frame for a sliding door, in particular for a sliding door according to the invention as described above. The threshold assembly comprises a threshold and a sealing strip, wherein the sealing strip is pivotably arranged on the threshold between a lowered and a raised position, wherein a pivot axis runs along the threshold, and wherein the threshold assembly further comprises an actuating element for raising the sealing strip, which is configured to raise the sealing strip from the lowered position when a leaf of the sliding door is moved along the threshold (in a displacement direction parallel to the threshold) into a closed position. The threshold can be one-part or multi-part and, for example, have a base body and a tread plate. For further features and advantages of the threshold and the sealing strip, reference is made to the above description.
[0040] Also within the scope of the present invention is a frame for a sliding door, in particular for a sliding door according to the invention as described above, comprising two vertical beams, an upper horizontal beam, and a threshold arrangement according to the invention as described above. For further features and advantages of the frame, reference is made to the above description. In particular, sealing elements of a sealing arrangement extending continuously in one plane can be arranged on the two vertical beams and the upper horizontal beam.
[0041] Further features and advantages of the invention will become apparent from the description, the claims, and the drawings. According to the invention, the above-mentioned and further-described features can be used individually or in combination in any convenient way. The embodiments shown and described are not intended to be exhaustive, but rather are exemplary in nature for describing the invention.

[0060] Fig. 16 shows the sliding door of Figure 13 in a schematic cross section with the leaf resting on the frame, in a schematic cross section.
[0061] Figure 1 shows a sliding door 10. A frame 12 fixed to the building has a threshold 14, two vertical beams 16, 18, and an upper horizontal beam 20. The threshold 14 and the beams 16, 18, 20 enclose a door opening 22. The frame can also have an additional panel 24, in particular with fixed glazing.
[0062] The sliding door 10 further comprises a leaf 26. The leaf 26 can selectively close or open the door opening 22. Figure 1 shows a partially open state.
[0063] To close the sliding door 10, the leaf 26 is pushed into a closed position in front of the door opening 22 (to the left in Figure 1) and then pressed against the frame 12 by operating a handle 28. For this purpose, the handle 28 is coupled in a conventional manner to carriages 30 and, if appropriate, other fittings (not shown in detail). Once the leaf 26 has been set aside (removed) from the frame 12 by appropriate operation of the handle 28, the leaf 26 can be moved along a guide rail 32, on which the carriages 30 rest, to uncover or cover the door opening 22. A leaf plane in which the leaf 26 extends flat (parallel to the drawing plane of Figure 1), is aligned parallel to the guide rail 32. The guide rail 32 runs along the threshold 14.
[0064] The leaf 26 is movable in the manner described above, on the one hand along the guide rail 32 and on the other hand perpendicular to the guide rail 32 or perpendicular to the leaf plane. The movement of the leaf 26 along the guide rail 32 to open or close the door opening 22 is only possible when the leaf 26 is positioned away from the frame 12. In particular, in the closed position, the leaf 26 can be moved perpendicular to the guide rail 32 to place the leaf 26 against the frame 12 or to position it away from the frame 12. The closed position, in which the leaf 26 completely covers the door opening 22, is defined by a stop (not shown in detail).
[0065] When placed against the frame 12, the leaf 26 rests against a sealing arrangement 34 that continuously surrounds the door opening 22. The sealing arrangement 34 has sealing strips 36a, 36b, 36c that extend along the two vertical beams 16, 18 and the upper horizontal beam 20. Furthermore, the sealing arrangement 34 has a pivotable sealing strip 38 that extends along the threshold 14.
[0066] In Figure 1, the sealing strip 38 is in a lowered position, in which it is flush with an upper surface 40 of the sill 14. When the sash 26 is closed, the sealing strip 38 is raised so that it rests against the front of the sash 26. This is illustrated in more detail below using two exemplary embodiments.
[0067] The sliding door 10 of Figure 1 is barrier-free. The upper side 40 of the threshold 14 is arranged at least approximately at the level of an adjacent pavement 42. Thus, in the lowered position, i.e., with the leaf 26 open, the sealing strip 38 is also arranged at least approximately at the level of the pavement 42. The pavement can be a floor surface inside and / or outside the building.
[0068] Figure 2 shows a sliding door 10 with a slightly open leaf 26, which is supported transversely to its leaf plane by a frame 12. Figure 2 shows a corner area between a threshold 14 and a vertical beam 16.
[0069] The threshold 14 has a tread plate 44 on its top side. A sealing strip 38 is arranged adjacent to the tread plate 44 on the threshold 14. In Figure 2, the sealing strip 38 is in a lowered position, in which it is flush with the tread plate 44.
[0070] A corner piece 46 is arranged in the corner area between the vertical beam 16 and the sill 14. The corner piece 46 is located directly below a sealing strip 36a attached to the vertical beam 16.
[0071] An actuating element 48 for the sealing strip 38 is arranged on the corner piece 46, facing the sash 26. When the sealing strip 38 is lowered or the sash 26 is positioned away from the frame 12, the actuating element 48 protrudes from the corner piece 46, specifically toward a front side 50 of the (sliding) sash 26 (see also Figure 5). The actuating element 48 protrudes beyond the plane of a circumferential sealing arrangement 34, which comprises the sealing strip 36a and the corner piece 46. In particular, the actuating element 48 protrudes transversely to the sill 14 or sealing strip 38 beyond a sealing lip 52 of the sealing strip 38 (see also Figure 9).
[0072] Figures 3 and 4 show the sliding door 10 with the leaf 26 closed and resting against the frame 12. Figure 3 shows the corner area of the threshold 14 and the vertical beam 16 with the corner piece 46. Figure 4 shows a corner area at the other end of the threshold 14 near the vertical beam 18. There, a further corner piece 54 is arranged below the sealing strip 36b. When the leaf 26 rests against the frame 12, the sealing strip 38 is in an upright position. The sealing strip 38 protrudes upwards over an upper side 40 of the threshold 14, here in particular the tread plate 44.
[0073] The sash 26 rests with its front side 50 against the sealing lip 52 of the sealing strip 38. Furthermore, the front side 50 of the sash 26 rests against the two corner pieces 46, 54 and the vertical sealing strands 36a, 36b, as well as a horizontal sealing strand 36c on an upper horizontal member 20 (see Figure 1). The sash 26 is thus sealed continuously around the frame 12 in the plane of its front side 50. The sealing strip 38, the sealing strands 36a, 36b, 36c, and the corner pieces 46, 54 thus form a closed, circumferential sealing arrangement 34 for sealing in a common sealing plane, namely the plane of the front side 50 of the sash 26.
[0074] When the sash 26 rests against the frame 12, specifically the circumferential sealing arrangement 34, in this embodiment the actuating element 48 is accommodated in the corner piece 36, compare Figure 6. This enables, on the one hand, the front-side sealing contact of the sash 26 against the corner piece 46.
[0075] On the other hand, the corner piece 46 can act as a stop for the actuating element 48 (see also Figure 10). The contact of the actuating element 48 with the corner piece 46 defines the raised position of the sealing strip 38. This also prevents the sealing strip 38 from being pivoted beyond the raised position, which could reduce the sealing effect.
[0076] In this embodiment, the sealing strip 38 has a sealing profile 56 into which a stiffening element 58 is embedded, see Figure 9a.
[0077] At a first end region 60 of the sealing profile 56, the sealing lip 52 is designed to bear against the sash 26. In the erected position of the sealing strip 38, the sealing lip 52 can be bent upwards relative to the stiffening element 58 due to contact with the sash 26, see Figures 8 and 10. The stop between the actuating element 48 and the corner piece 46 thus defines the orientation of the stiffening element 58 for the erected position of the sealing strip 38; the sealing lip 52 is deformed by the sash 26 resting against the frame 12, so that the elasticity of the sealing profile 56 in the first end region 60 defines the pressing of the sealing lip 52 against the front side 50 of the sash 26.
[0078] A second end region 62 of the sealing profile 56 is fixed to the threshold 14, here to its upper tread plate 44 (see in particular Figure 9a). For this purpose, the second end region 62 can be received and clamped in a groove 64 of the tread plate 44; projections and / or ribs can be provided in the groove 64, which compress and / or engage behind the sealing profile 56. An insert 63 can be embedded in the sealing profile 56 in the second end region 62. This can improve the hold of the sealing profile 56 on the tread plate 44.
[0079] The two end regions 60, 62 are arranged on different sides of the stiffening element 58.
[0080] Between the second end region 62 and the stiffening element 58, a deformation section 66 is formed in the sealing profile 56. In the deformation section 66, the sealing profile 56 has a reduced thickness. The deformation section 66 thus defines a pivot axis 68 about which the sealing strip 38 is pivoted between the lowered and the raised position; see also Figure 7 for the lowered position and Figure 8 for the raised position. In Figures 7 and 8, the pivot axis 68 runs perpendicular to the plane of the drawing along the threshold 14. Thus, the pivot axis 68 also extends parallel to the plane of the sash 26 and to a guide rail 32 on which the sash 26 can be moved with its carriages 30 (provided it is removed from the frame 12).
[0081] In this embodiment, the actuating element 48 is fixed to the sealing strip 38, in particular to its stiffening element 58 (see Figure 9a). Here, the actuating element 48 encompasses the stiffening element 58 on the top and bottom. Furthermore, a screw of the actuating element 48 can penetrate the sealing profile 56 and the stiffening element 58 (not shown in detail). A rotation axis 70 of the actuating element 48 thus corresponds to the pivot axis 68 of the sealing strip 38. A separate mounting of the actuating element 48 is not provided in this embodiment.
[0082] When the sash 26 is open, i.e., when it is placed away from the frame 12 and pushed out of the closed position, an edge 72 between the front side 50 and a narrow side 74 of the sash 26 facing the vertical beam 16 is arranged behind the part of the actuating element 48 projecting beyond the sealing lip 52 when viewed along the sill 14 or along the guide rail 32, see Figures 2 and 9.
[0083] When the wing 26 is pushed into the closed position, the edge 72 strikes the actuating element 48 shortly before the closed position is reached. A contact surface 76 is formed on the actuating element 48, onto which the wing 26 runs (see Figure 5). The contact surface 76 is inclined relative to the pivot axis 70, which here coincides with the rotation axis 68. In particular, the contact surface 76 is curved.
[0084] As the sash 26 is pushed further closed, the actuating element 48 and the sealing strip 38 are tilted about their common rotation or pivot axis 70, 68, with the edge 72 of the sash 26 sliding off the contact surface 76 of the actuating element 48. When the sash 26 (still positioned away from the frame 12) has reached the closed position, a tip 78 of the actuating element 48 rests against the front side 50 of the sash 26 (see Figures 11 and 12). The sealing strip 38 is then in an intermediate position. In the intermediate position, the sealing lip 52 does not yet touch the sash 26. The actuating element 48 still protrudes from the corner piece 46 and projects toward the sash 26. When the sash 26 is placed against the frame 12 by operating the handle 28 (see Figure 1), the actuating element 48 with the sealing strip 38 is raised further until the (fully) raised position is reached, see Figure 10.The actuating element 48 is now received in the corner piece 46. In the area of the sealing lip 52, the sealing profile 56 can be bent further upward relative to the stiffening element 58; see also Figure 8. Both the sealing lip 52 and the tip 78 of the actuating element 48 rest against the front side 50 of the leaf 26 when it is fully closed and locked by turning the handle 28; see Figures 8 and 10.
[0085] An additional seal 80 is also provided on the underside of the sash 26. When the sash 26 rests against the frame 12, the additional seal 80 rests against a vertical sealing surface 82 within the sill 14 (see Figures 8 and 10). When the sash 26 is positioned away from the frame 12, the additional seal 80 is lifted from the vertical sealing surface 82 (see Figures 7, 9, and 11). Thus, the additional seal 80 does not touch the sealing surface 82 of the sill 14 when the sash 26 is moved.
[0086] Figures 13 and 14 show a further embodiment of a sliding door 10' with a leaf 26 and a frame 12. In Figure 13, the leaf 26 partially exposes a door opening 22; a sealing strip 38 is in a lowered position. In Figure 14, the leaf 26 is in a closed position, in which it has moved toward a vertical member 16 of the frame 12 and covers the door opening 22; the sealing strip 38 is in a raised position.
[0087] With regard to its basic functionality, the sliding door 10' shown in Figures 13 and 14 corresponds to the sliding door 10 sketched in Figure 1 and shown in more detail in Figures 2 to 12. In this respect, reference is made to the preceding description. The following primarily describes the differences with regard to the design and actuation of the sealing strip 38. In the sliding door 10', an actuating element 84 for the sealing strip is designed in the form of a lever with two legs 86, 88 that are developed relative to one another. The two legs 86, 88 can enclose an angle of approximately 75° (e.g., 75°+ / -10°). The actuating element 84 is rotatable about a horizontally extending axis of rotation 90 that is aligned orthogonally to a threshold 14 and a guide rail 32 running in the threshold 14 (see Figure 1).
[0088] The leg 86 of the actuating element 84 extends upward from the rotation axis 90. When the sash 26 is open, the leg 86 is inclined away from the vertical beam 16 toward the sash 26, see Figure 13. The leg 88 engages under the sealing strip 38. When the sash 26 is open, the leg 88 runs horizontally.
[0089] Shortly before the sash 26 reaches the closed position (see Figure 14) when being pushed closed, a narrow side 74 of the sash 26 facing the vertical beam 16 strikes the leg 86 of the actuating element 84. As the sash 26 is moved further into the closed position, the leg 86 is pressed toward the vertical beam 16, causing the actuating element 84 to rotate about its axis of rotation 90. The leg 88 is thereby deflected upward and raises the sealing strip 38 into the open position. When the sash 26 is placed against the frame 12, the sealing strip 38 is no longer raised on the sliding door 10'.
[0090] The sealing strip 38 in the sliding door 10' is formed with a support profile 92 and a sealing element 94, compare Figures 15, 15a and 16. The sealing element 94 is attached to the support profile 92.
[0091] The support profile 92 has a dome groove 96 with a circular cross-section, see in particular Figure 15a. A joint projection 98 of the threshold 14 engages in the dome groove 96. Due to the engagement of the joint projection 98 in the dome groove 96, the sealing strip 38 is pivotally mounted on the threshold 14, with a pivot axis 68 extending along the threshold 14 parallel to the guide rail 32 and the leaf plane of the leaf 26. The rotation axis 90 of the actuating element 84 and the pivot axis 68 of the sealing strip 38 run perpendicular to each other in the sliding door 10'.
[0092] A stop section 100 is formed on the support profile 92 beyond the dome groove 96, as viewed from the sealing element 94. In the raised position of the sealing strip 38, the stop section 100 rests against the threshold 14, preventing the sealing strip 38 from rising any further (see Figure 16).
[0093] The sealing element 94 has two sealing lips 52, 102. When the sash 26 is positioned against the frame 12, the sealing lip 52 rests against a front side 50 of the sash 26 (see Figure 16). The sealing lip 52 can be bent upward relative to the support profile 92. At the same time, the sealing lip 102 rests against the underside of the sash 26. To achieve this, the sealing lip 102 is arranged below the sealing lip 52; moreover, the sealing lip 102 protrudes further than the sealing lip 52 (see also Figure 15). Due to the underside contact with the sash 26, the sealing lip 102 is bent downward relative to the support profile 92.
[0094] In the sliding door 10', the sealing strip 38, together with sealing strands 36a-36c (see also Figure 1) and compressible corner pieces 104, also forms a sealing arrangement 34 that completely surrounds the door opening 22. In particular, the sealing lip 52, together with the sealing strands 36a-36c and the corner pieces 104, provides a seal in the plane of the front side 50 of the leaf 26.
[0095] In summary, the invention relates to a threshold arrangement with a pivoting sealing strip for a sliding door with a sash that can be moved along a track and which can be placed against a frame in a horizontal direction perpendicular to the track or placed away from the frame. When the sash is open, the sealing strip is lowered so that it is flush with a sill. When the sash is pushed closed along the track, the sealing strip is at least partially raised. When the pushed-closed sash is placed against the frame, the sealing strip can be raised further. When the sash is resting against the frame, the raised sealing strip seals against a vertical front side of the sash that is aligned parallel to the track. In particular, the sash is sealed against the frame all the way around in the plane of its front side, which is achieved by the sealing strip and other sealing structures fixed to the frame.
