Abstract

The invention relates to a sill assembly for a sliding door, comprising a pivotable sealing strip, said sliding door comprising a leaf which can be moved along a slide rail and which can be attached to or removed from a frame in the horizontal direction perpendicular to the slide rail. When the sash body is opened, the sealing strip is lowered, so that the sealing strip is terminated flush with the threshold. When the sash body is pushed upwards along the sliding rail, the sealing strip is at least partially erected. When the pushed sash body is attached to the frame, the sealing strip can be further erected. When the sash body is attached to the frame, the erected sealing strip seals the vertical front side of the sash body, which is oriented parallel to the slide rail. In particular, the leaf body is sealed in a continuous circumferential manner relative to the frame in the plane of the front side thereof, which is caused by the sealing profile and other stationary sealing structures on the frame side.

Description

Technical Field

[0001] The present invention relates to a sliding door, comprising a frame and a fan, wherein the fan is movable perpendicular to its fan plane in a closed position to bring the fan against the frame or lower it from the frame, and wherein the fan lowered from the frame is movable within its fan plane to release or close the door opening. Background Technology

[0002] For example, such sliding doors are known from EP 2 829 679 B1 or from the manual "Roto Patio Inowa - Intelligent Hardware for High-Density Sliding Systems", which can be downloaded from the following website on July 11, 2023. https: / / media.ftt.roto-frank.com / # / reader / 2e064a3c-8013-39c7-c9d3-2c65bec15d79.pdf For the surrounding seal, the threshold of the sliding door protrudes to a certain extent above the horizontal height of the walkway.

[0003] To achieve a full seal between the door leaf and the threshold, various solutions have been proposed for pivot doors (with a single-sided hinge and a leaf that can pivot about a vertical axis).

[0004] For example, DE 10 2017 101 557 A1 describes a threshold having a threshold housing that reliably functions as a high threshold when the door is in the closed position and is completely unobstructed when the door is fully open, without requiring external power to change the door's state. This is achieved by the threshold having a horizontal height flush with the ground and a raised horizontal height, and the threshold having a motion mechanism driven by a rack movable in the closing direction of the door (perpendicular to the frame), the rack being connected to a trigger that extends beyond the horizontal height flush with the ground and forms a functional unit with the door until the door is about to complete the closing process. An eccentric shaft is rotatable via the rack, on which a pinion and a lifting cam are arranged, located below the threshold. The threshold is pivotally hinged to the threshold housing via a rotary joint. Thus, when the door moves toward the threshold, the threshold is raised. The door can stop on a stop surface at the end of the threshold.

[0005] A similar sill is known from DE 10 2017 101 559 A1, wherein the drive mechanism for driving the camshaft to raise the sill includes a deflectable actuating device. Here, the actuating device may consist of a guided spring steel strip or a steel cable core guided in a flexible outer sheath, or it may also consist of a guided actuating chain.

[0006] Another similar threshold for terrace or balcony doors is known from DE 10 2006 029 353 B3. In this threshold, an adjusting element for raising a strip that can be partially recessed into the threshold is slidably supported in the threshold along the closing direction of the door (perpendicular to the frame).

[0007] DE 1 509 280 A describes a door seal for a hinged or sliding door, wherein a sealing strip embedded in the floor is pressed upward when the door is closed. A double-armed lever lifts the sealing strip in the vertical direction. The lever is angled at its point of rotation. One arm of the lever is operatively connected to the sealing strip, and the other short arm of the lever is operatively connected to the narrow face of the door facing the pivot.

[0008] A similar lifting threshold is known from DE 10 2017 101 555 A1. Here, a pivot lever for raising the threshold is pivotally supported about a vertical pivot axis and acts on the threshold via a cam mechanism, such that the threshold abuts against the lower side of the door when the door is closed.

[0009] Other door sills with a sealing strip that can translate vertically are known from US 7,028,740 B2, US2011 / 0265386 A1 or EP 3458669 B1. Summary of the Invention

[0010] One objective of this invention is to achieve an effective seal for a sliding door of the type described at the beginning, which has an unobstructed or at least minimally obstructed threshold.

[0011] This task is accomplished according to the invention by the sliding door according to claim 1, the threshold assembly according to claim 21, and the frame according to claim 22. Advantageous embodiments are given in the dependent claims and the specification.

[0012] According to the present invention, a sliding door is provided. The sliding door has a frame and a fan. In the closed position, the fan can move perpendicular to its fan plane to abut against or lower from the frame. The movements for abutting the fan against the frame and lowering the fan from the frame are substantially strictly perpendicular to the fan plane. The movements for abutting or lowering the fan are, in particular, a pure translational movement. In the closed position, the fan completely covers the door opening. The closed position can also be referred to as the closed position or end position of the fan. The fan lowered from the frame can move within its fan plane to release or close the door opening.

[0013] The threshold may have a slide rail along which the fan body can move when it is lowered from the frame. The fan body may have a slide block for moving the fan body on the slide rail. Preferably, the slide block is coupled to a handle, and operation of the handle causes the fan body to move perpendicular to the slide rail. For this purpose, the slide block may have a suitable mechanism, such as with a lateral guide. The movement triggered by the slide block when the handle is operated has essentially no component along the slide rail; therefore, the movement is strictly perpendicular to the plane of the slide rail or the fan body.

[0014] The frame has a sill on which a sealing strip is arranged, pivotable between a lowered position and an upright position. One pivot axis of the sealing strip extends parallel to the plane of the fan body. Therefore, the pivot axis extends parallel to the direction of movement of the fan body. The pivot axis can be an imaginary axis or a solid axis of pivotal movement of the sealing strip. The pivotable sealing strip is easily actuated to move between the lowered and upright positions, is particularly capable of being loaded, and requires only a small structural height below its upper surface, for example, for mechanisms to fix or support the sealing strip or for raising the sealing strip.

[0015] In the lowered position, the sealing strip preferably terminates flush with the upper surface of the sill, and especially the upper surface of the sill pedal. In the lowered position (which occurs when the sill is open), the sealing strip can be easily crossed, particularly by a walker or wheelchair, or without the risk of tripping. The pedal creates a connection where the sill is flush with the walking surface. Of course, the pedal can be made of sheet metal or other suitable materials, such as plastic. In particular, the pedal can be manufactured as an extruded profile or injection molded part.

[0016] In the upright position, the sealing strip protrudes beyond the upper surface of the door sill, especially the upper surface of the door sill plate. The upright sealing strip enables effective sealing of the sliding door.

[0017] In its position abutting against the frame, the fan body contacts the erected sealing strip with its front side (facing the frame). This reliably creates a seal in the area below the fan body. The front side generally corresponds to the outer side of the fan body. Preferably, the fan body, in its position abutting against the frame, rests circumferentially against the sealing assembly of the frame. In particular, the frame may have a sealing assembly that continuously surrounds the fan body in a plane for abutment, wherein the sealing strip is part of the surrounding sealing assembly. This results in a complete seal of the fan body relative to the frame. Potential leakage points are avoided by the in-plane seal at the front side of the fan body. Furthermore, the in-plane seal simplifies the design of the sealing assembly for a reliable seal independent of manufacturing and installation tolerances and any wear.

[0018] Direction or position description, such as above or below, refers to the installed state of a sliding door in the description of the invention.

[0019] The sliding door has an operating element for raising the weatherstripping, which is configured to lift the weatherstripping from its lowered position when the door panel (lowered from the frame) is moved to the closed position. Therefore, the operating element has already raised the weatherstripping when the door panel moves to the closed position parallel to its plane. In other words, the weatherstripping is at least partially raised as the door panel moves in a direction parallel to the threshold (along the slide rail). This allows for contact between the weatherstripping and the front of the frame when the door panel rests against it, eliminating the risk of the weatherstripping getting caught on the door panel.

[0020] The control element typically works in conjunction with the fan body in such a way that the fan body contacts the control element during the final segment of its movement, such as the last 0.5 to 5 centimeters, as it moves to the closed position. Specifically, it can be configured such that, as the fan body moves, a vertical fan body frame erfassens the control element with its narrow side, oriented laterally to the plane of the fan body, or the edge of the frame on that narrow side. This prevents the control element from interfering with the entry opening.

[0021] The actuating element is preferably rotatable about a rotation axis. This enables a stable configuration and helps keep manufacturing costs low.

[0022] The operating element and sealing strip are preferably configured such that when the door panel is moved from the closed position to release the door opening, the sealing strip transitions to a lowered position due to gravity. Alternatively or additionally, a spring element may be provided to bring the sealing strip into the lowered position.

[0023] In one advantageous embodiment, the actuating element is configured to fully bring the sealing strip into the upright position when the fan body is moved to the closed position. This simplifies the interaction between the fan body and the actuating element.

[0024] In an alternative, equally advantageous embodiment, the actuating element is configured to raise the sealing strip to an intermediate position when the fan body is moved to the closed position. Then, as the fan body rests against the frame, the sealing strip is brought from the intermediate position to an upright position. Further bringing the sealing strip from the intermediate position to the upright position can be achieved by the actuating element and / or directly by the fan body. In the intermediate position, the sealing strip is raised / erected less than in the upright position. A relatively large erection movement on the sealing strip can be achieved through two stages of lifting.

[0025] In an advantageous embodiment, the axis of rotation of the operating element is oriented perpendicular to the pivot axis of the sealing strip. Here, the axis of rotation typically extends perpendicular to the plane of the fan body. This simplifies the configuration of the operating element. This embodiment is particularly suitable for situations where the sealing strip should be fully erected when the fan body is moved to the closed position.

[0026] In an extended embodiment, the actuating element is a rotatably supported lever having two arms. The first arm engages the sealing strip from below, and the second arm projects upward so as to be deflected by the fan body when it moves to the closed position. Here, the motion transmission ratio of the actuating element can be adjusted by changing the arm lengths to achieve full erection of the sealing strip over a smaller displacement stroke of the fan body.

[0027] The angle between the arms 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 15° + / - 5° to move the sealing strip from a lowered position to an upright position.

[0028] In an alternative, equally advantageous embodiment, the axis of rotation of the actuating element corresponds to the pivot axis of the sealing strip, preferably wherein the actuating element is fixed to the sealing strip. This reduces the complexity of the mechanism and, in particular, eliminates the need for a separate support for the actuating element. This embodiment is particularly suitable for situations where, when the fan body moves to the closed position, the sealing strip should first rise to an intermediate position and then fully erect when the fan body rests against the frame.

[0029] In an extended embodiment, the actuating element has a particularly curved contact surface that is inclined relative to the pivot axis for contacting the fan body. The inclination or curvature of the contact surface can affect the motion transmission ratio of the actuating element when the lowered fan body is moved to the closed position. Preferably, the contact surface protrudes horizontally beyond the sealing strip in the lowered position. Thus, the fan body can rub against the actuating element with an edge perpendicular to the fan body frame when moved to the closed position without contacting the sealing strip.

[0030] 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 abutting against the sill body, and a second end region of the sealing profile is fixed to the sill, particularly to the sill pedal, and wherein a deformable section is formed in the sealing profile between the second and first end regions, defining a pivot axis. In other words, the deformable section acts as a membrane hinge. This enables a particularly simple and robust configuration of the sill assembly. Furthermore, the connection of the sealing profile to the sill avoids the formation of gaps between the sealing strip and the sill, particularly between the sealing strip and the pedal. Moreover, the deformable section of the sealing profile enables virtually wear-free pivoting of the sealing strip. A cavity may be provided within the sealing lip; such a sealing lip may also be referred to as a bladder seal.

[0031] In an advantageous extension of this embodiment, the sealing strip has a reinforcing element for the sealing profile, which is arranged between the deformable section and the sealing lip. The reinforcing element improves the stability of the sealing strip under load due to stepping or driving. Furthermore, reinforcing the sealing profile allows for a greater clamping force acting on the fan body, which improves the sealing effect. The sealing profile can be injection molded or cast onto the reinforcing element. This allows for economical manufacturing of the sealing strip. In particular, the reinforcing element can be injection molded over or overcast over the sealing profile. In other words, the reinforcing element can be embedded in the sealing profile. This results in a particularly durable connection between the reinforcing element and the sealing profile.

[0032] In an alternative, equally advantageous embodiment, the sealing strip has a carrying profile and a sealing element held on the carrying profile, wherein the carrying profile is pivotally supported on the sill. This simplifies the installation of the sealing strip on the sill. Furthermore, the defined support of the carrying profile on the sill allows for particularly precise determination of the sealing strip's mobility. In particular, the carrying profile may have a ball-and-socket groove extending along a pivot axis into which an articulated protrusion of the sill engages. The ball-and-socket groove typically has a rounded, particularly circular, cross-section. The circular shape of the ball-and-socket groove facilitates hinged pivoting of the sealing strip relative to the sill. The articulated protrusion preferably extends for at least 70%, particularly at least 85%, of the length along the ball-and-socket groove. The articulated protrusion may consist of multiple segments.

[0033] In an advantageous extension of this embodiment, the bearing profile has a stop section for abutting against the sill when the sealing strip is in the upright position. This stop section prevents the sealing strip from accidentally rising further beyond the upright position, thus ensuring that the sealing strip exerts a sufficiently large clamping force on the front side of the sash.

[0034] The frame may have vertical edges and corner pieces arranged in the corner areas where the vertical edges meet the threshold, with the fan body resting against these corner pieces in a position abutting against the frame. Therefore, the corner pieces in this corner area contribute to a seal between the fan body and the frame. The corner pieces may be part of a sealing assembly that continuously surrounds the fan body in a plane. In particular, the corner pieces may be compressed when the fan body rests against the frame.

[0035] Preferably, the actuating element is received in the corner piece when the fan body is abutting against the frame. This embodiment is particularly suitable for an actuating element that can be erected about a pivot axis extending parallel to or coinciding with the pivot axis. Therefore, the actuating element does not compromise the sealing effect at the corner area.

[0036] Preferably, when the sealing strip is in the upright position, the operating element rests against the corner piece. Therefore, the corner piece acts as a stop for the operating element. This prevents the sealing strip from accidentally rising further beyond the upright position. This ensures that the sealing strip exerts a sufficiently large clamping force on the front side of the fan body.

[0037] The sealing strip may have one sealing lip for abutting against the fan body on the front side and another sealing lip for abutting against the fan body on the lower side. This achieves a particularly effective seal. The sealing profile of the sealing strip or the free end of the sealing element facing the fan body may be U-shaped, such that the two sealing lips are each formed by one of the supporting edges of the U-shaped end.

[0038] An additional seal can be arranged on the underside of the sash, wherein a vertical sealing surface is formed within the sill for abutting the additional seal when the sash rests against 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 the surrounding sealing assembly used for abutting the sash at the front. The vertical sealing surface within the sill is essentially located below the upper side of the sill.

[0039] The present invention also relates to a threshold assembly for a sliding door, particularly for the frame of the sliding door according to the invention described above. The threshold assembly has a threshold and a sealing strip, wherein the sealing strip is pivotally arranged on the threshold between a lowered position and an upright position, wherein the pivot axis extends along the threshold, and wherein the threshold assembly further has an actuating element for raising the sealing strip, the actuating element being configured to lift the sealing strip from the lowered position when the door leaf moves along the threshold (along a direction of movement parallel to the threshold) to the closed position. The threshold can be one-piece or multi-piece and, for example, has a body and a footplate. Further features and advantages of the threshold and sealing strip are described above.

[0040] The present invention also relates to a frame for a sliding door, particularly for the sliding door according to the invention described above, the frame comprising two vertical side frames, a top horizontal side frame, and a threshold assembly according to the invention described above. Further features and advantages of the frame are described above. In particular, sealing elements of a sealing assembly that continuously surrounds the two vertical side frames and the top horizontal side frame in a single plane can be arranged.

[0044] Figure 1 A sliding door 10 is shown. The building-fixed frame 12 has a threshold 14, two vertical side frames 16, 18, and a horizontal side frame 20 above. The threshold 14 and the side frames 16, 18, 20 form a door opening 22. The frame may also have another area 24, particularly with fixed glass.

[0045] The sliding door 10 also has a leaf 26. The leaf 26 can selectively close or open the door opening 22. Figure 1 The text shows the partially open state.

[0046] To close the sliding door 10, push the fan 26 to the closed position in front of the door opening 22 (in Figure 1 From the center to the left), the fan body is then abutted against the frame 12 by manipulating the handle 28. For this purpose, the handle 28 is coupled to the slide 30 and, if necessary, other hardware (not shown in detail). When the fan body 26 is lowered (removed) from the frame 12 by correspondingly manipulating the handle 28, the fan body 26 can move along the slide rail 32 (on which the slide rail 30 rests) to release or cover the door opening 22. The fan body 26 extends planarly along the fan body plane (parallel to...). Figure 1 The drawing plane is oriented parallel to the slide rail 32. The slide rail 32 extends along the threshold 14.

[0047] As previously described, the fan 26 is movable along the slide rail 32 on one hand, and perpendicular to the slide rail 32 on the other, or rather, perpendicular to the plane of the fan. The movement of the fan 26 along the slide rail 32 (in order to release or close the door opening 22) is only possible when the fan 26 is lowered from the frame 12. Especially in the closed position, the fan 26 can move perpendicular to the slide rail 32 to bring the fan 26 against or lower it from the frame 12. The closed position (in which the fan 26 completely covers the door opening 22) is defined by a stop not shown in detail.

[0048] With the door frame 12 in place, the sash 26 rests against a sealing assembly 34 that continuously surrounds the door opening 22. The sealing assembly 34 has sealing strips 36a, 36b, and 36c that extend along the two vertical frame edges 16 and 18 and the upper horizontal frame edge 20. Furthermore, the sealing assembly 34 has a pivotable sealing strip 38 extending along the door sill 14.

[0049] exist Figure 1 In the middle position, the sealing strip 38 is in a lowered position, in which it terminates flush with the upper side 40 of the sill 14. When the sill 26 is closed, the sealing strip 38 is raised so that it rests against the sill 26 at the front. This is shown in more detail below according to two embodiments.

[0050] Figure 1 The sliding door 10 is barrier-free. The upper side 40 of the threshold 14 is positioned at least approximately at the horizontal height of the adjacent walkway 42. Therefore, the sealing strip 38 is also positioned at least approximately at the height of the walkway 42 in the lowered position, i.e., when the sash 26 is open. The walkway can be an interior or exterior floor surface of the building.

[0051] Figure 2 A sliding door 10 is shown, having a slightly open sash 26 that extends laterally from a frame 12 across its sash plane. Figure 2 The corner area between the threshold 14 and the vertical frame 16 is shown in the image.

[0052] The sill 14 has a foot pedal 44 on its upper side. Adjacent to the foot pedal 44, a sealing strip 38 is arranged on the sill 14. Figure 2 In the middle, the sealing strip 38 is in a lowered position, in which the sealing strip terminates flush with the pedal 44.

[0053] A corner piece 46 is arranged in the corner area between the vertical frame 16 and the threshold 14. The corner piece 46 is located directly below the sealing strip 36a fixed to the vertical frame 16.

[0054] In the corner piece 46, an operating element 48 for the sealing strip 38 is arranged facing the fan body 26. When the sealing strip 38 is lowered or the fan body 26 is lowered from the frame 12, the operating element 48 extends from the corner piece 46, i.e., towards the front side 50 of the (push-up / closed) fan body 26, see also... Figure 5 Here, the actuating element 48 protrudes beyond the plane of the surrounding sealing assembly 34, which includes a sealing strip 36a and a corner piece 46. In particular, the actuating element 48 protrudes laterally beyond the sealing lip 52 of the sealing strip 38, either across the sill 14 or the sealing strip 38. See also... Figure 9 .

[0055] exist Figure 3 and Figure 4 The image shows the state of the sliding door 10 when the sash 26 is closed and against the frame 12. Figure 3 The corner area with corner piece 46 is shown for the threshold 14 and the vertical frame 16. Figure 4 The corner area at the other end of the threshold 14, in the case of the vertical frame 18, is shown. There, another corner piece 54 is arranged below the sealing strip 36b.

[0056] When the fan body 26 is abutted against the frame 12, the sealing strip 38 is in an upright position. Here, the sealing strip 38 protrudes upwards beyond the upper side 40 of the sill 14, particularly the foot pedal 44. The fan body 26 rests its front side 50 against the sealing lip 52 of the sealing strip 38. Furthermore, the front side 50 of the fan body 26 rests against the two corner pieces 46, 54, the vertical sealing strips 36a, 36b, and the horizontal sealing strip 36c on the upper horizontal frame 20 (see...). Figure 1 The fan body 26 thus continuously surrounds and seals relative to the frame 12 within the plane of its front side 50. The sealing strips 38, 36a, 36b, 36c, and corner pieces 46, 54 thus form a closed surrounding sealing assembly 34 for sealing within a common sealing plane, namely the plane of the front side 50 of the fan body 26.

[0057] When the fan body 26 rests against the frame 12, specifically the surrounding sealing assembly 34, in this embodiment the operating element 48 is received in the corner piece 46, see [reference needed]. Figure 6 This allows the fan body 26 to be sealed against the corner piece 46 on the front side.

[0058] On the other hand, the corner piece 46 can also serve as a stop for the operating element 48, see also Figure 10 The upright position of the sealing strip 38 is defined by abutting the actuating element 48 against the corner piece 46. This also prevents the sealing strip 38 from pivoting beyond the upright position, which could reduce the sealing effect.

[0059] In this embodiment, the sealing strip 38 has a sealing profile 56, and the reinforcing element 58 is embedded in the sealing profile. See also Figure 9a .

[0060] A sealing lip 52 is formed on the first end region 60 of the sealing profile 56 for abutting against the fan body 26. In the upright position of the sealing strip 38, the sealing lip 52 can bend upward relative to the reinforcing element 58 through contact with the fan body 26, see [reference needed]. Figure 8 and Figure 10 Therefore, the orientation of the reinforcing element 58 is defined for the upright position of the sealing strip 38 by the stop between the manipulating element 48 and the corner piece 46; the sealing lip 52 is deformed by the fan body 26 abutting against the frame 12, so that the sealing lip 52 forms a pressing on the front side 50 of the fan body 26 by the elasticity of the sealing profile 56 in the first end region 60.

[0061] The second end region 62 of the sealing profile 56 is fixed to the sill 14, which is in turn fixed to the tread 44 on the upper side of the sill, see in particular. Figure 9a For this purpose, the second end region 62 can be received and clamped in a groove 64 of the pedal 44; a protrusion and / or rib can be provided in the groove 64, which compresses and / or engages the sealing profile 56. An insert 63 can be embedded in the sealing profile 56 in the second end region 62. This improves the fixation of the sealing profile 56 on the pedal 44.

[0062] The two end regions 60 and 62 are arranged on different sides of the reinforcing element 58.

[0063] Between the second end region 62 and the reinforcing element 58, a deformable section 66 is constructed in the sealing profile 56. In the deformable section 66, the sealing profile 56 has a reduced thickness. Therefore, the deformable section 66 defines a pivot axis 68 about which the sealing strip 38 pivots between a lowered position and an erected position; see also the lowered position. Figure 7 (Lowered position) and see also the upright position. Figure 8 Pivot axis 68 in Figure 7 and Figure 8 The pivot axis 68 extends perpendicularly to the drawing plane along the threshold 14. Therefore, the pivot axis 68 also extends parallel to the fan plane of the fan body 26 and the slide rail 32, on which the fan body 26 (as long as it is lowered from the frame 12) can move with its slide 30.

[0064] In this embodiment, the operating element 48 is fixed to the sealing strip 38, and particularly to the reinforcing element 58 of the sealing strip, see [reference needed]. Figure 9aHere, the actuating element 48 surrounds the reinforcing element 58 from both the top and bottom. Furthermore, a screw of the actuating element 48 can pass through the sealing profile 56 and the reinforcing element 58 (not shown in detail). Therefore, the pivot axis 70 of the actuating element 48 corresponds to the pivot axis 68 of the sealing strip 38. In this embodiment, no separate support for the actuating element 48 is provided.

[0065] When the fan body 26 is opened, i.e., lowered from the frame 12 and removed from the closed position, the edge 72 between the front side 50 of the fan body 26 and the narrow side 74 facing the vertical frame 16 is positioned behind the portion of the operating element 48 that protrudes beyond the sealing lip 52 when viewed along the sill 14 or along the slide rail 32. See [reference needed]. Figure 2 and Figure 9 .

[0066] As the fan body 26 is pushed into the closed position, just before reaching the closed position, edge 72 contacts the operating element 48. A contact surface 76 is formed on the operating element 48, and the fan body 26 collides with this contact surface. See [link to relevant documentation]. Figure 5 The contact surface 76 is inclined relative to the pivot axis 70 (which here coincides with the pivot axis 68). The contact surface 76 extends in a particularly curved manner.

[0067] As the fan body 26 continues to be pushed up, the operating element 48 and the sealing strip 38 tilt about their common rotation / pivot axes 70, 68, wherein the edge 72 of the fan body 26 slides on the contact surface 76 of the operating element 48. When the fan body 26 (still lowered from the frame 12) reaches the closed position, the tip 78 of the operating element 48 rests against the front side 50 of the fan body 26, see Figure 11 and Figure 12 Then, the sealing strip 38 is in the intermediate position. In the intermediate position, the sealing lip 52 has not yet contacted the fan body 26. The operating element 48 still extends from the corner piece 46 and protrudes toward the fan body 26.

[0068] By manipulating handle 28, the fan body 26 is placed against frame 12 (see...). Figure 1 At this point, the operating element 48 and the sealing strip 38 are further raised until they reach a (fully) upright position, see [reference]. 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 may be further bent upward relative to the reinforcing element 58, see also Figure 8 When the fan body 26 is fully closed and locked by turning the handle 28, both the sealing lip 52 and the tip 78 of the operating element 48 are against the front side 50 of the fan body. See [link / reference]. Figure 8 and Figure 10 .

[0069] Here, an additional sealing element 80 is also provided on the lower side of the fan body 26. When the fan body 26 is attached to the frame 12, the additional sealing element 80 is attached to a vertical sealing surface 82 inside the sill 14, see [reference]. Figure 8 and Figure 10 When the fan body 26 is lowered from the frame 12, the additional seal 80 is lifted from the vertical sealing surface 82, see [reference]. Figure 7 , Figure 9 and Figure 11 Therefore, the additional seal 80 will not scratch the sealing surface 82 of the sill 14 when the fan body 26 moves.

[0070] Figure 13 and Figure 14 Another embodiment of the sliding door 10' is shown, which has a sash 26 and a frame 12. Figure 13 In the middle, the fan body 26 partially releases the door opening 22; the sealing strip 38 is in a lowered position. Figure 14 In the closed position, the fan body 26 is pushed against a vertical frame 16 of the frame 12 and blocks the door opening 22; the sealing strip 38 is in the upright position.

[0071] Regarding basic working methods, Figure 13 and Figure 14 The sliding door 10' shown corresponds to the one in Figure 1 Indicatively and in Figures 2 to 12 The sliding door 10 is shown in more detail. Please refer to the preceding description for this. The differences in configuration and operation of the sealing strip 38 will be described below with priority.

[0072] In the sliding door 10', the operating element 84 for the sealing strip is constructed as a lever with two arms 86, 88 angled to each other. The two arms 86, 88 can form an angle of approximately 75° (e.g., 75° + / - 10°). The operating element 84 is rotatable about a horizontally extending pivot axis 90, which is orthogonal to the sill 14 and the slide rail 32 extending in the sill 14 (see...). Figure 1 ) Orientation.

[0073] The arm 86 of the operating element 84 extends upward from the pivot axis 90. When the fan body 26 is open, the arm 86 tilts away from the vertical frame 16 toward the fan body 26, see [reference needed]. Figure 13 Arm 88 engages below sealing strip 38. When fan body 26 is open, arm 88 extends horizontally.

[0074] When the fan body 26 is pushed up, it will almost reach the closed position (see...). Figure 14Before the sliding door 10' is closed, the narrow side 74 of the fan 26 facing the vertical frame 16 contacts the arm 86 of the operating element 84. As the fan 26 moves further into the closed position, the arm 86 is pressed against the vertical frame 16, causing the operating element 84 to rotate about its pivot axis 90. As a result, the arm 88 is deflected upward and the sealing strip 38 is raised into an upright position. When the fan 26 is against the frame 12, the sealing strip 38 is not raised further in the sliding door 10'.

[0075] The sealing strip 38 in the sliding door 10' is formed by the carrying profile 92 and the sealing element 94, see [reference]. Figure 15 , 15a and Figure 16 The sealing element 94 is fixed to the bearing profile 92.

[0076] The bearing profile 92 includes a ball-and-socket groove 96 with a circular cross-section, see in particular Figure 15a A jointed protrusion 98 of the sill 14 engages in a ball joint groove 96. The sealing strip 38 is hingedly supported on the sill 14 via the jointed protrusion 98 engaging in the ball joint groove 96, wherein a pivot axis 68 extends along the sill 14 parallel to the plane of the slide rail 32 and the fan body 26. The pivot axis 90 of the operating element 84 and the pivot axis 68 of the sealing strip 38 extend perpendicularly to each other in the sliding door 10'.

[0077] On the bearing profile 92, viewed from the sealing element 94, a stop section 100 is formed on the other side of the ball groove 96. In the upright position of the sealing strip 38, the stop section 100 rests against the sill 14, preventing the sealing strip 38 from rising further. See [reference needed]. Figure 16 .

[0078] The sealing element 94 has two sealing lips 52 and 102. When the fan body 26 is against the frame 12, the sealing lip 52 abuts against the front side 50 of the fan body 26, see [reference]. Figure 16 Here, the sealing lip 52 can be curved upward relative to the bearing profile 92. Meanwhile, the sealing lip 102 rests abutting against the fan body 26 from below. To achieve this, the sealing lip 102 is positioned below the sealing lip 52; furthermore, the sealing lip 102 protrudes more than the sealing lip 52, see also... Figure 15 By abutting against the lower side of the fan body 26, the sealing lip 102 bends downward relative to the bearing profile 92.

[0079] In the sliding door 10', sealing strip 38 and sealing strips 36a-36c (see also...) Figure 1 Together with the compressible corner piece 104, they form a surrounding sealing assembly 34 that closes the door opening 22. In particular, the sealing lip 52, together with the sealing strips 36a-36c and the corner piece 104, causes a seal in the plane of the front side 50 of the fan body 26.

[0080] In summary, the present invention relates to a sill assembly with a pivotable sealing strip for a sliding door having a sash movable along a slide rail, the sash being able to rest against or descend from the frame in a horizontal direction perpendicular to the slide rail. When the sash is opened, the sealing strip is lowered such that it terminates flush with the sill. When the sash is pushed up along the slide rail, the sealing strip is at least partially erected. When the pushed-up sash is brought against the frame, the sealing strip can be further erected. When the sash is against the frame, the erected sealing strip seals the vertical front side of the sash, which is oriented parallel to the slide rail. In particular, the sash continuously circumferentially seals relative to the frame within the plane of its front side, which is caused by the sealing strip and other fixed sealing structures on the frame side.
