[0001] Sliding door insert for retrofitting a sliding door in a sliding door cassette of an expandable sliding door, sliding door cassette with sliding door insert and method for retrofitting
[0002] Description
[0003] The present invention relates to a sliding door insert for retrofitting a sliding door in a sliding door cassette of an expandable sliding door, a sliding door cassette for an expandable sliding door with a sliding door, and a method for retrofitting a sliding door in a sliding door cassette of an expandable sliding door.
[0004] An expandable sliding door can have movable half-shells that spread apart within a sliding door frame when the sliding door is closed. These half-shells are brought into contact with seals on the frame to seal the sliding door to the frame. To open the sliding door, the half-shells are pulled together to make the sliding door thinner and allow it to slide into a slot next to the frame.
[0005] The frame for such an expandable sliding door can be pre-installed during the construction of a building without actually installing the door. The frame can then be used for various purposes until the need arises. For example, the frame can be covered over to create a doorless passageway, or a shelving system can be installed in the passageway to close it off.
[0006] Likewise, a particularly simple sliding door can be hung on a guide rail of the frame. This particularly simple sliding door cannot be expanded and cannot change its thickness. This particularly simple sliding door can serve as a privacy screen, as it cannot seal against the frame's seals for the expandable sliding door. A non-expandable sliding door can also be synonymously referred to as a constant-thickness sliding door. For example, WO 2023 / 274674 A1 describes a multifunctional building wall module system.
[0007] There may be a need, among other things, for a sliding door insert for retrofitting a sliding door in a sliding door cassette of an expandable sliding door with improved properties, in particular, for example, a soundproof seal.
[0008] Such a need can be met by a sliding door insert for retrofitting a sliding door to a sliding door cassette of an expandable sliding door, a sliding door cassette for an expandable sliding door with a sliding door, and a method for retrofitting a sliding door to a sliding door cassette of an expandable sliding door according to the main claims. Advantageous embodiments are defined in the dependent claims and described in the description.
[0009] In the approach presented here, a non-expandable sliding door panel is hung in an existing track for an expandable sliding door, and a frame configured for the expandable sliding door is supplemented with additional panels. The panels cover a gap between the non-expandable sliding door panel and a frame contour designed for the expandable sliding door panel, allowing the non-expandable sliding door panel to seal against the panels via seals, or the panels to seal against the sliding door panel via seals.
[0010] The approach presented here allows the closed simple sliding door to provide particularly good sound insulation, as air gaps around the sliding door are closed by contact seals.
[0011] According to a first aspect of the invention, a sliding door insert for retrofitting a sliding door cassette of an expandable sliding door with a sliding door is proposed, wherein the sliding door insert comprises a sliding door arrangement and a panel set, wherein the sliding door arrangement comprises a non-expandable sliding door leaf and is designed to be suspended in a guide rail of the sliding door cassette, wherein the panel set is designed to modify a frame of the sliding door cassette, which is configured for the expandable sliding door, for the non-expandable sliding door leaf, wherein the panel set comprises a stop panel, a guide panel and an insertion panel, wherein the stop panel is designed to be arranged on a stop side of the frame and to seal a stop side of the sliding door leaf, wherein the guide panel is designed toto be arranged on an upper side of the frame and to seal an upper side of the sliding door leaf, and wherein the insertion panel is designed to be arranged on an insertion side of the frame and to seal an insertion side of the sliding door leaf. The guide panel has at least one lowerable seal for sealing the upper side.
[0012] According to a second aspect of the invention, a sliding door cassette for an expandable sliding door with a sliding door is proposed, wherein a non-expandable sliding door leaf of a sliding door arrangement of a sliding door insert according to the first aspect is suspended in a guide rail of the sliding door cassette and a panel set of the sliding door insert modifies a frame of the sliding door cassette for the non-expandable sliding door leaf, wherein a stop panel of the panel set is arranged on a stop side of the frame and seals a stop side of the sliding door leaf, wherein a guide panel of the panel set is arranged on an upper side of the frame and seals an upper side of the sliding door leaf, and wherein an insertion panel of the panel set is arranged on an insertion side of the frame and seals an insertion side of the sliding door leaf.
[0013] According to a third aspect of the invention, a method for retrofitting a sliding door cassette of an expandable sliding door with a sliding door is proposed, wherein a non-expandable sliding door leaf of a sliding door arrangement of a sliding door insert according to an embodiment of the first aspect of the invention is suspended in a guide rail of the sliding door cassette, wherein a frame of the sliding door cassette configured for the expandable sliding door is modified using a panel set of the sliding door insert for the sliding door leaf, wherein a stop panel of the panel set is arranged on a stop side of the frame to seal a stop side of the sliding door leaf, wherein a guide panel of the panel set is arranged on an upper side of the frame to seal an upper side of the sliding door leaf, and wherein an insertion panel of the panel set is arranged on an insertion side of the frame,to seal one insertion side of the sliding door leaf.
[0014] A sliding door cassette can be a wall structure prepared to accommodate an expandable sliding door, which has a passageway that can be closed by the sliding door and a slot adjacent to the passageway for receiving the opened sliding door. The passageway is surrounded by a frame of the sliding door cassette. The slot and the passageway are connected by at least one guide rail of the sliding door cassette. The sliding door cassette can be installed in a wall of a building to provide a means of installing a sliding door, in particular an expandable one. The slot is arranged in a cavity between a paneling of the wall. The cavity is preferably 125 mm wide and the paneling is 12.5 mm thick on both sides, so that a wall thickness of 150 mm is achieved.
[0015] The expandable sliding door has a mechanism that controls the distance between two half-shells of the sliding door. To open the sliding door, the mechanism pulls the half-shells together, reducing their distance and thus making the sliding door thinner. In the thin position, the sliding door moves along the guide rail into the drawer, opening the passage. The expandable sliding door is usually electrically driven. The expandable sliding door can essentially disappear completely into the drawer.
[0016] To close the expandable sliding door, the drawn-together half-shells are moved along the guide rail from the slot into the passageway. The mechanism spreads them apart in the passageway when one of the sliding door's stop sides reaches one of the frame's stop sides. As the half-shells spread apart, the distance between them increases until they seal against the frame's seals all the way around. Spreading apart compresses the seals, ensuring a tight seal for the passageway.
[0017] In the approach presented here, the sliding door cassette for the expandable sliding door is retrofitted with a simple, non-expandable sliding door. The non-expandable sliding door is retrofitted as a sliding door insert, and the frame is modified so that the simple sliding door is also sealed with gaskets. The non-expandable sliding door, in particular, features a one-piece sliding door leaf.
[0018] The sliding door insert consists of several parts and is assembled in a specific sequence. A sliding door assembly can be provided pre-assembled. A panel set can be provided as individual parts.
[0019] The sliding door arrangement can comprise all components that are attached to the sliding door leaf or are at least partially movable with the sliding door leaf. The sliding door arrangement can have at least two guides for hooking into the guide rail. The guides can in particular be roller guides that can roll in the guide rail. The guides can be arranged on a top side or guide side of the sliding door leaf and in particular can be connected to the sliding door leaf in a height-adjustable manner in order to be able to align the sliding door leaf relative to the guide rail. The guides can be hooked into the guide rail. After being hooked in, the guides can be concealed by side panels of the sliding door leaf. The sliding door arrangement can also have a drive mechanism for moving the sliding door leaf back and forth between a closed position and an open position.The sliding door assembly may include a locking mechanism for locking the sliding door panel at least in the closed position.
[0020] The panel set can have a matching panel or several matching panels for each side of the frame. The different sides of the frame can be referred to as the stop side, the guide side and the insertion side. The different sides of the frame can therefore be modified using one-piece or multi-piece panels. In particular, the guide panel and the insertion panel can each be two-part, since a gap for the non-expandable sliding door leaf is formed between each two parts of the panel. The non-expandable sliding door leaf is moved back and forth in this gap between the passage and the insertion when opening and closing. The stop panel can be one-piece. The panel set can have seals that seal against the sealing surfaces of the sliding door leaf. Alternatively or additionally, the sliding door leaf can have seals that seal against the sealing surfaces of the panel set.
[0021] A lowerable seal can be a movable, controllable seal. The lowerable seal can be raised or lowered. In the raised state, the lowerable seal can be lifted from a surface of the sliding door leaf and not touch the sliding door leaf. In the lowered state, the lowerable seal can rest against the surface of the sliding door leaf and seal against the sliding door leaf. The lowerable seal can be controlled electrically or mechanically, for example, via a control cam. The lowerable seal can be installed in any direction and can, for example, be moved upwards or sideways to seal. In particular, the guide panel can have two lowerable seals. The seals can seal on opposite sealing surfaces of the sliding door leaf, i.e., on the inside and outside of the sliding door leaf.
[0022] The stop panel, the insert panel, and / or the sliding door assembly can have seal receptacles for the original frame seals. To modify the frame, the original frame seals can be removed and installed on at least the stop panel, the insert panel, and / or the sliding door leaf.
[0023] A seal mount can, for example, be a profiled groove. A foot of the original seal can be inserted into the seal mount and mechanically interlocked or elastically clamped in the seal mount. The original seals of the frame can be used, as they already have the correct dimensions. The seal mounts can be arranged in pairs symmetrically to a center plane of the sliding door insert. The original seals can then seal on both sides of the sliding door.
[0024] The seal mounts can be positioned on the sliding door panel, particularly on the insertion side. This allows the original seals to only come into contact with their sealing surfaces on the insertion panel immediately upon closing the sliding door, preventing the original seals from permanently rubbing against the sliding door panel. Other seals can also be used as an alternative to the original seals.
[0025] Alternatively, the sliding door assembly may include at least one liftable seal for sealing against the guide panel. The liftable seal may essentially correspond to a lowerable seal. The liftable seal may be arranged on the top side of the sliding door leaf. The liftable seal may extend upward to seal against a sealing surface of the guide panel.
[0026] The sliding door assembly can include at least one retractable seal for sealing against the floor. The retractable seal can be located on the underside of the sliding door leaf. The retractable seal can use the floor beneath the sliding door as a sealing surface. The lower retractable seal can have an enlarged range of motion. This prevents the retractable seal from rubbing against uneven surfaces or dirt on the floor.
[0027] At least the stop panel and / or the insertion panel can be designed to be attached to the original sealing recesses of the frame. The stop panel and / or the insertion panel can be mechanically interlocked in the sealing recesses. Likewise, the stop panel and / or the insertion panel can be clamped into the sealing recesses and / or magnetically attached to the edge profiles of the frame provided with the sealing recesses. By attaching them to the original sealing recesses, the panel set can be installed on the frame without permanent modification and removed again without leaving residue. In particular, the panel set can be installed without tools.
[0028] The sliding door arrangement can have a drive to move the sliding door leaf back and forth between a closed position and an open position. The drive can be arranged on the insertion side of the sliding door leaf and be designed to be arranged within a slot of the sliding door cassette. A drive can comprise an electric motor. The electric motor can, for example, engage with a rack of the guide rail via a gearwheel. Likewise, the drive can have a belt running over pulleys, which is moved relative to the sliding door leaf by the electric motor. In this case, either the sliding door leaf can be coupled to the belt and the electric motor can be coupled to the guide rail, or the belt can be coupled to the guide rail and the electric motor can be coupled to the sliding door leaf.The drive can be discreetly integrated into the sliding door arrangement within the drawer and positioned in a protected manner within the drawer.
[0029] The sliding door leaf assembly may include a control unit. The control unit may be located on the insertion side of the sliding door leaf. The control unit may be located near the drive. The control unit may be discreetly integrated into the sliding door assembly within the insertion and protected within the insertion.
[0030] The stop panel and at least part of the stop side of the frame can be removable. The sliding door cassette can have a maintenance pocket behind the stop panel and the stop side for accommodating at least part of the sliding door leaf. Components of the sliding door assembly that are normally hidden in the slot of the sliding door cassette when the stop panel is installed can be accessible if the sliding door leaf is at least partially arranged in the maintenance pocket. To service the sliding door insert, the stop panel and at least part of the stop side of the frame can be removed in order to make the maintenance pocket arranged behind the stop panel and the stop side accessible for accommodating at least part of the sliding door leaf.The sliding door leaf can be arranged at least partially in the maintenance pocket in order to make components of the sliding door arrangement that would otherwise be hidden in the insert when the stop panel is mounted accessible for maintenance.
[0031] A maintenance pocket can be another lockable compartment opposite the insert. The maintenance pocket can be located in a cavity between the paneling of the sliding door cassette. The guide rail can extend into the maintenance pocket. The sliding door leaf can be moved far enough into the maintenance pocket that components of the sliding door assembly that would otherwise be inaccessible in the insert, such as the drive and control system, are located in the passage and are thus accessible. The maintenance pocket can also be used when assembling the sliding door assembly. For example, the stop side of the sliding door leaf can be placed in the maintenance pocket first and then the insert side can be aligned with the guide rail. The guides of the sliding door assembly can also be coupled to the guide rail in this order.When the sliding door assembly is hooked into the guide rail, the sliding door assembly can be moved from the maintenance pocket into the drawer and the maintenance pocket can be closed by the stop side and the drawer panel.
[0032] It should be noted that some of the possible features and advantages of the invention are described herein with reference to different embodiments of methods on the one hand and devices on the other. A person skilled in the art will recognize that the features can be combined, adapted, or exchanged as appropriate to achieve further embodiments of the invention.
[0033] Embodiments of the invention are described below with reference to the accompanying drawings, wherein neither the drawings nor the description are to be construed as limiting the invention.
[0034] Fig. 1 shows a representation of a sliding door cassette for an expandable sliding door with a built-in sliding door insert according to an embodiment; and
[0035] Figs. 2a to 2d show detailed representations of a sliding door insert according to an embodiment.
[0036] The figures are merely schematic and not to scale. Like reference numerals denote like or equivalent features.
[0037] Fig. 1 shows a representation of a sliding door cassette 100 for an expandable sliding door with a built-in sliding door insert 102 according to an exemplary embodiment. The sliding door cassette 100 is arranged in an opening 104 in a wall 106 of a building (not shown). The sliding door cassette 100 is designed as a drywall construction with planked studwork on both sides and completely closes the opening 104 except for a door-shaped through opening 108 through the wall 106. The through opening 108 is framed by a frame 110 of the sliding door cassette. The frame 110 is designed, in conjunction with the expandable sliding door when expanded in the closed state, to close and seal the through opening 106. For this purpose, the expandable sliding door is pressed from the inside against circumferential seals or sealing surfaces of the frame 110 when expanded.Next to the passage opening 108, a slot 112 of the sliding door cassette 100 is arranged in the stud frame between the planking on both sides. The slot 112 is designed to accommodate the unspreadable, expandable sliding door in the open state, so that the expandable sliding door virtually disappears into the wall 106. A horizontal guide rail for the expandable sliding door runs along an upper side of the passage opening 108 and an upper side of the slot 112. The guide rail runs in a notch in the upper side of the passage opening 108.
[0038] Instead of the expandable sliding door, the sliding door insert 102 is installed here. The sliding door insert 102 has a sliding door assembly 114 with a non-expandable sliding door leaf 116 and a cover set 118. The sliding door leaf 116 is a single piece. The sliding door assembly 114 is attached to the guide rail, and the non-expandable sliding door leaf 116 is suspended from the guide rail. Since the non-expandable sliding door leaf 116 has the same thickness when closed and open, it protrudes behind a plane of the paneling on both sides of the sliding door cassette 100 when closed and cannot directly seal against the seals or sealing surfaces of the frame 110. Therefore, the cover set 118 is mounted in the frame and has seals or sealing surfaces that match the non-expandable sliding door leaf 116.
[0039] The panel set 118 is at least three-part and consists of a stop panel 120, a guide panel 122, and a slide-in panel 124. The stop panel 120 is arranged on a stop side 126 of the frame 110. The guide panel 122 is arranged on an upper side 128 of the frame 110. The slide-in panel 124 is arranged on an insertion side 130 of the frame 110. The panel set 118 bridges gaps between the seals or sealing surfaces of the frame 110 and the non-expandable sliding door leaf 116. In one embodiment, the sliding door assembly 114 has an electric drive for the sliding door leaf 116. The drive is arranged on the insertion side of the sliding door leaf 116 and, during normal operation of the sliding door insert 102, is arranged within the insert 112. The drive can be attached to the sliding door leaf 116 and coupled to the guide rail, for example, via a belt.The drive can also be directly coupled to the guide rail and, for example, connected to the sliding door leaf 116 via a belt. The drive can automatically open and close the sliding door leaf 116. The drive allows the sliding door leaf 116 to be retracted into the slot 112 flush with the frame 110 or the insertion panel 124, eliminating the need for a handle.
[0040] In one embodiment, the sliding door assembly 114 further includes a drive control unit. Thanks to the integrated control unit, the sliding door insert 102 can be delivered plug-in ready, is easy to install, and only requires a power supply. The control unit can be installed on the drive and thus disappears into the slot 112 of the sliding door cassette 100.
[0041] In one embodiment, the sliding door leaf 116 has a control surface 132. The sliding door insert 102 can be controlled via the control surface. The control surface 132 can be touch-sensitive and also have a display 134. For example, an image from a door camera 136 integrated into the control surface 132 on an external side can be displayed via the display 134. The image can be provided automatically, for example, when the doorbell is rung via the control surface 132.
[0042] In one embodiment, the sliding door cassette 100 has a maintenance pocket 138 on a side opposite the insert 112, which, like the insert 112, is arranged between the planking on both sides of the stud frame. The guide rail extends into the maintenance pocket 138. During normal operation, the maintenance pocket 138 is closed by the stop side 126 of the frame 110. If the expandable sliding door or the non-expandable sliding door arrangement 114 is to be serviced, the stop side 126 is at least partially removed, or at least a portion of the stop side 126 and the stop panel 120 are removed, and the maintenance pocket 138 is opened. The non-expanded sliding door or the sliding door leaf 116 can then be moved at least partially into the maintenance pocket 138.This provides access to components of the sliding door assembly 114 which are located within the drawer 112 during normal operation and are therefore inaccessible.
[0043] Figs. 2a to 2d show detailed views of a sliding door insert 102 according to one exemplary embodiment. The sliding door insert 102 essentially corresponds to the sliding door insert in Fig. 1. In Figs. 2a, 2b, and 2c, the panels of the panel set 118 are shown in sectional views through the frame 110. Fig. 2d shows a sectional view through an underside of the non-expandable sliding door leaf 116.
[0044] In Fig. 2a, the stop side 126 of the frame 110 is shown in a horizontal section. As in Fig. 1, a view from below is shown. The sliding door cassette 100 has the paneling 200 on an inner and an outer side. The stud frame 202 is arranged in a space between the paneling 200. Edge profiles 204 are fastened to the stud frame 202. The edge profiles 204 each enclose an edge of the paneling 200 facing the passage opening 108 in order to protect the edge from damage. The edge profiles 204 have seal receptacles 206 for seals of the expandable sliding door. The seal receptacles 206 are formed as recesses in a profile cross-section of the edge profiles and are arranged set back behind the edge. A stop profile 208 is arranged between the edge profiles 206.The stop profile 208 is also set back behind the edges of the planking 200 and closes the gap between the planking 200.
[0045] In one embodiment, the stop profile 208 is removable to make the maintenance pocket 138 in the intermediate space accessible.
[0046] Here, the stop panel 120 of the panel set 118 is arranged in front of the stop profile 208. The stop panel 120 modifies the stop side 126 for the non-expandable sliding door leaf 116. The stop panel 120 forms a receiving area for the sliding door leaf 116. The stop panel 120 fills a gap between the edges of the paneling 200 and the non-expandable sliding door leaf 116. When closed, the sliding door leaf 116 moves into a recess formed by the stop panel 120 and, in the closed state, seals against the stop panel 120 via at least one contacting seal. The seal can be a lip seal, for example. The seal can be arranged on the stop panel 120 and seal against a sealing surface of the sliding door leaf 116. Alternatively, the seal can be arranged on the sliding door leaf 116 and seal against a sealing surface of the stop panel 120.
[0047] In one embodiment, the stop panel 120 has two seal receptacles 206 for original seals 210 of the sliding door cassette 100. The seal receptacles 206 are formed as recesses in a profile cross-section of the stop panel 120. The original seals 210 can be removed from the seal receptacles 206 of the edge profiles 204 before installing the stop panel 120 and inserted into the seal receptacles 206 of the stop panel 120. Alternatively, the original seals 210 can be supplied with the sliding door insert 102.
[0048] In one embodiment, the stop panel 120 is attached to the seal receptacles 206 of the edge profile 204. For example, the stop panel 120 can be positively snapped into the seal receptacles 206 via snap elements. Alternatively, the stop panel 120 can be clamped into the seal receptacles 206 via clamping elements. The stop panel 120 can also be held to the edge profiles 204 via magnets.
[0049] In Fig. 2b, the insertion side 130 of the frame 110 is shown in a horizontal section. As in Fig. 2a, a view from below is shown. The insertion side 130 essentially corresponds to the stop side 126 and has the essentially identical edge profiles 204 on the edges of the paneling 200 facing the through opening 108, with the seal receptacles 206, as well as the paneled stud frame 202 on the outside and inside of the sliding door cassette 100 with the intermediate space therebetween. The intermediate space here forms the insertion 112. In contrast to the illustration in Fig. 2a, an opening 212 of the insertion 112 is arranged between the edge profiles 204. The insertion panel 124 modifies the insertion side 130 for the non-spreadable sliding door leaf 116, reduces the opening 212 to a width suitable for the non-spreadable sliding door leaf 116 and seals the sliding door leaf 116 via at least two contacting seals.The seals can be lip seals, for example. The seals can be arranged on the insertion panel 124 and seal against the sealing surfaces of the sliding door leaf 116. Alternatively, the seals can be arranged on the sliding door leaf 116 and seal against the sealing surfaces of the insertion panel 124.
[0050] The insert panel 124 is in two parts, with one part of the insert panel 124 being arranged on the inside of the sliding door leaf 116 and the other part of the insert panel 124 being arranged on the outside of the sliding door leaf 116. One of the seals is arranged between each part and the sliding door leaf 116.
[0051] In one embodiment, the seals are arranged on the sliding door leaf 116. For this purpose, the sliding door leaf has two seal receptacles 206 for original seals 210 of the sliding door cassette 100. The seal receptacles 206 are formed as recesses in a profile cross-section of the sliding door leaf. The original seals 210 can be removed from the seal receptacles 206 of the edge profiles 204 before installing the insert panel 124 and inserted into the seal receptacles 206 of the sliding door leaf 116. Alternatively, the original seals 210 can be supplied with the sliding door insert 102.
[0052] In one embodiment, the sliding door leaf 116 has a widened portion 214 at its end located in the insert 112. The widened portion 214 is wider than the opening 212 modified by the insert panel 124. The seal receptacles 206 are located directly in front of the widened portion 214. Thus, the widened portion 214 serves as a support surface for the seals.
[0053] In one embodiment, the parts of the stop panel 120 are attached to the sealing receptacles 206 of the edge profiles 204. For example, the parts can be positively snapped into the sealing receptacles 206 via snap elements. Alternatively, the parts can be clamped into the sealing receptacles 206 via clamping elements. The parts can also be held to the edge profiles 204 via magnets.
[0054] In Fig. 2c, the upper side 128 of the frame 110 is shown in vertical section. The upper side 128 essentially corresponds to the stop side 126 and the insertion side 139 and has the essentially identical edge profiles 204 on the edges of the paneling 200 facing the passage opening 108, with the sealing receptacles 206, as well as the stud frame 202 paneled on the outside and inside of the sliding door cassette 100 with the intermediate space therebetween. In contrast to the illustration in Figs. 2a and 2b, the horizontal guide rail 216 of the sliding door cassette 100 is arranged in the intermediate space here. The guide rail 216 is attached to a cross member of the stud frame 202.
[0055] The non-expandable sliding door leaf 116 is movably mounted in the guide rail via roller drives 218. The roller drives 218 are connected to the sliding door leaf 116 between two extensions of the outer side and the inner side of the sliding door leaf 116 in a resulting recess on an upper side of the sliding door leaf 116. The guide panel 122 modifies the upper side 128 of the frame 110 for the non-expandable sliding door leaf 116 and seals the sliding door leaf 116 via at least two seals. The seals can be arranged on the guide panel 122 and seal against sealing surfaces of the sliding door leaf 116. Alternatively, the seals can be arranged on the sliding door leaf 116 and seal against sealing surfaces of the guide panel 122.
[0056] The guide panel 122 is in two parts, with one part of the guide panel 122 being arranged on the inside of the sliding door leaf 116 between the edge profile 204 and the sliding door leaf 116, and the other part of the guide panel 122 being arranged on the outside of the sliding door leaf 116 between the edge profile 204 and the sliding door leaf 116. One of the seals is arranged between each part and the sliding door leaf 116. The extensions of the outside and inside extend between the parts of the guide panel 122. In one embodiment, the seals are lowerable seals 220. The lowerable seals 220 are driven by an actuator. The lowerable seals 220 are controlled by the control system of the sliding door insert 102. The lowerable seals 220 are lifted from the sealing surfaces and do not touch the sealing surfaces when the sliding door leaf 116 is moved along the guide rail 216.At least when the through opening 108 is closed, the lowerable seals 220 are placed on the sealing surfaces and then seal against the sealing surfaces by contact.
[0057] In one embodiment, the lowerable seals are horizontally movable and arranged on the guide panel 122. The sealing surfaces are arranged on the extensions of the outer and inner sides of the sliding door leaf 116.
[0058] In one embodiment, the parts of the guide panel 122 are attached to the sealing receptacles 206 of the edge profiles 204. For example, the parts can be positively snapped into the sealing receptacles 206 via snap elements. Alternatively, the parts can be clamped into the sealing receptacles 206 via clamping elements. The parts can also be held to the edge profiles 204 via magnets.
[0059] Fig. 2d shows a vertical section of a lower edge of the non-expandable sliding door leaf 116. No cover of the cover set is arranged at the lower edge. The sliding door leaf 116 has a recess in its underside in which a lowerable seal 220 is arranged. When lowered, the lowerable seal 220 seals against the bottom 222 of the frame 110. The lowerable seal 220 is lifted from the bottom 222 when the sliding door leaf 116 moves along the guide rail.
[0060] In the following, possible embodiments of the invention are summarized again or presented with slightly different wording.
[0061] A simple sliding door for the cassette of a retractable door is presented. This inexpensive, non-spreadable sliding door is particularly soundproof and features an electric drive. The sliding door has no handgrip and, thanks to the electric drive, can be retracted flush with the door frame into the wall.
[0062] Panels on the door frame close the opening, which is actually too large for the retractable door. The panels are easily removable.
[0063] The sliding door is provided as a kit for complementing a cassette for an expandable sliding door arrangement. The kit comprises a non-expandable door and a trim kit. A first subset of the trim kit trims the opening into which the sliding door retracts when opened and is configured to accommodate seals. A second subset of the trim kit trims the receiving area into which the sliding door retracts when closed and is configured to accommodate seals. A third subset of the trim kit trims the area at the top of the sliding door into which the sliding door retracts when closed and has retractable seals.
[0064] The door can have one, preferably two, lowerable seals at the bottom.
[0065] The first subset and / or the second subset can be attached to the cassette's seal holders using form-fitting snap-in elements, magnets, or clamping elements. The seals are removed beforehand.
[0066] The first subset is two-part, with one part on the inside and one part on the outside of the sliding door. The second subset is one-piece, meaning it's connected at least at the top.
[0067] The sliding door is preferably designed as a single body. A drive is mounted on the end of the door that remains in the cassette. A control unit is also mounted on the end of the door that remains in the cassette.
[0068] The sliding door can have control panels, touchscreens on the inside of the door, and / or a peephole camera. To convert or retrofit a cassette with such a sliding door, the four vertical seals are removed, if present. The vertical seals are already the correct length. Furthermore, the two horizontal seals are removed, if present.
[0069] Then the first subset and the second subset are preferably attached to the prof, which served to fix the seals, and the previously dismantled vertical seals are attached to the facings, finally the third facing is attached.
[0070] For maintenance purposes, the second panel can be removed along with the end piece underneath, and the sliding door can be moved into the service space so that work can be carried out on the drive and control system at the rear.
[0071] Finally, it should be noted that terms such as "having," "comprising," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not to be considered as limitations.
