SLIDING WALL WITH SEALING ARRANGEMENT

Description

TECHNICAL FIELD

[0001] The present invention relates to a sliding wall which has at least the following: at least one sliding sash, a frame which has at least one receiving and guide channel in which the at least one sliding sash is displaceably guided and a sealing arrangement for at least partially sealing a gap between the frame and the sliding sash at least in a closed position of the sliding sash. STATE OF THE ART

[0002] Sliding walls with at least one sliding panel are commonplace. They allow for a wide view and can even be constructed without thresholds and with a comparatively small frame. The sliding panels are usually multi-glazed and generally have a continuous profile. Such sliding walls are also referred to as sliding doors or sliding windows.

[0003] In the case of sliding walls, good tightness is essential and, to achieve good tightness, good sealing of the gap between the sliding sash and the frame is essential, at least when the sliding sash is in the closed position.

[0004] A variety of sealing arrangements have been developed to solve this problem. For example, it is known to provide one or more brush seals on both sides of the sliding sash, on the corresponding inner sides of the frame, with their free ends resting against the sliding sash. However, the sealing effect of these brush seals is rather limited. Furthermore, due to their contact with the sliding sash, they increase the forces required to move the sliding sash.

[0005] It is also known to design at least one of the seals of the sealing arrangement as an inflatable seal, whose cross-section can be enlarged by inflation in the closed position so that the gap between the sliding sash and the frame can be tightly sealed. However, this solution requires the provision of a compressor and other pneumatic components, which is not always desirable.

[0006] DE 10 2007 039 069 discloses a sliding wall comprising a frame and a sliding sash movable relative thereto. Furthermore, the sliding sash is provided with a movable auxiliary frame, which has a seal and presses the sash against the frame when closed. However, this complex mechanism obstructs visibility through the sliding sash.

[0007] AT 518105 A1 discloses a sliding wall according to the preamble of claim 1, which has a frame mounted on magnets and a sliding sash movable relative thereto, with a magnetically movable sealing strip provided. Implementing this solution would require magnets of a size that would significantly exceed the size of the magnets schematically illustrated in this document. This is disadvantageous. PRESENTATION OF THE INVENTION

[0008] The invention therefore has the task of further developing the sealing arrangement of the sliding window in such a way that the gap between the frame and the sash can be very well sealed in the closed position using simple structural means.

[0009] The invention achieves this object by the subject matter of claim 1.

[0010] Advantageous embodiments can be found in the subclaims.

[0011] According to the characterising part of claim 1, it is firstly provided that the sealing arrangement has at least one sealing strip arranged in the receiving and guide channel of the frame and movable perpendicularly or substantially perpendicularly to a main plane of the sliding sash, which sealing strip can be moved into a gap-sealing position in which it bears against the sliding sash, in particular against its sash frame, and into a gap-open position in which it does not bear or substantially does not bear against the sliding sash.

[0012] In this way, the gap, which is perpendicular to the main plane of the sliding sash between the frame and the sliding sash, can be easily sealed in the area of ​​the movable sealing strip when the sliding sash is closed. It can also be completely or essentially completely opened again when the sliding sash is opened, so that the sliding sash is not hindered, or only slightly hindered, by friction in the area of ​​the sealing strip when moving into the open position. This makes it easy to achieve good wind and water tightness and sound insulation.

[0013] According to the characterizing part of claim 1, it is further provided that the sealing strip is assigned a drive device, with which the sealing strip as a whole can be moved perpendicularly or substantially perpendicularly to the sliding sash. The drive device can be implemented in a variety of ways. The term "drive device" does not include a device for enlarging the cross-section of the sealing strip using pneumatics.

[0014] In addition, according to the characterizing part of claim 1, it is further provided, since this can be easily implemented structurally, that the drive device has a drive mechanism with which the sealing strip can be moved preferably as a whole perpendicularly or substantially perpendicularly to the sliding sash.

[0015] It is also provided that the drive mechanism in turn has a purely mechanically acting or an electric motor-acting drive means in order to move one or more mechanically acting elements or a mechanically acting device of the drive mechanism.

[0016] To ensure proper guidance of the sealing strip during its sliding movement, it can be provided that the sealing strip is slidably guided in a sliding groove – particularly in a part of the frame – from which it protrudes outward, at least in the gap-sealing position. Here, it can be moved, for example, by a mechanical device driven by the drive mechanism, such as a drive rod, or directly by the drive mechanism, so that the sliding guide then forms the only mechanically acting device of the drive mechanism.

[0017] The drive means can, for example, be designed in a simple manner as a handle or as an electric motor.

[0018] Two, three, or more sealing strips can be provided, which together form a non-circumferentially closed or a circumferentially closed sealing frame that can be pushed against the sliding sash by the drive mechanism. According to a particularly advantageous variant of the invention, it can be provided that four of the movable sealing strips form a sealing frame, in particular a sealing frame extending on four sides of the frame and which can be placed as a whole against the frame, so that a frame-like and preferably circumferentially closed seal is then formed on four sides of the frame between the sliding sash and the frame when the sliding sash is in the closed position. This is also advantageous for achieving good sound insulation on the respective sliding element. In addition, very good tightness is achieved, even in driving rain.

[0019] In this case, at least two of the sealing strips are preferably provided in horizontally aligned receiving and guide channels of horizontally aligned frame profiles and two of the sealing strips are provided in vertically aligned receiving and guide channels of vertically aligned frame profiles, wherein the sliding sash also engages in the vertically aligned receiving and guide channels at least in the closed state.

[0020] According to a further variant of the invention, it can be provided that the sliding sash with the one or more movable sealing strips, in particular with the sealing frame, can be moved and pressed in the closed position essentially perpendicular to its main plane against one, two or more further sealing strips of the sealing arrangement, which are formed on the opposite side of the sliding sash in the receiving and guide channel of the frame. For this purpose, the sliding sash must be somewhat movable perpendicular to its main plane, for example, displaceable or slightly pivotable. In this way, the gap between the sliding sash and the frame can be well sealed on the two opposite sides of the sliding sash, even though movable sealing strips are formed on the frame only on one side of the sliding sash.

[0021] According to an advantageously compact structural design of the drive mechanism, it can be provided that the drive mechanism has a movable drive rod assigned to the respective movable sealing strip, which is aligned parallel to the sealing strip and is movable, wherein at least one deflection device is provided for each sealing strip, with which a linear movement of the drive rod parallel to the sliding sash can be converted into a movement of the movable sealing strip perpendicular or substantially perpendicular to the sliding sash.

[0022] In this case, it can further be advantageous for the respective sealing strip to have a sealing profile made of elastomer and a base strip made of metal or plastic. The base strip allows the drive mechanism to be easily coupled to the sealing strip. It can preferably be moved together with the sealing profile as a unit.

[0023] It can also be provided that the respective drive rod and the respective sealing strip are slidably guided with the base strip in grooves of a retaining strip or retaining and abutment strip, which is attached to the frame or directly formed or connected in one piece with the frame. This design is simple and offers good functional reliability.

[0024] If the frame has several sides, it is then advantageous that at least one of the drive rods and one of the movable sealing strips is arranged on each side of the frame.

[0025] To ensure a well-functioning drive mechanism, it is also advantageous if the drive rods on adjacent sides of the frame are coupled to each other at a corner via a corner deflection device.

[0026] The use of drive rods and corner deflection devices offers the advantage that the one or more drive rods can be moved by the drive means, in particular, they can be moved together. The drive means can be a manually movable handle coupled to the drive rod via one or more gear elements. However, it is also conceivable for the drive means to be an electric motor coupled to at least one of the drive rods via one or more gear elements.

[0027] When it comes to the design of the deflection device, the specialist can consider a variety of options. They can consider using a lever mechanism or a combination of rollers and levers.

[0028] It can thus be provided that the respective deflection device simply has a roller and a ramp in the form of an inclined plane on which the roller can roll.

[0029] In order to simplify the return from the sealing position, it can further be provided that the respective deflection device has a return spring.

[0030] According to another embodiment, the deflection device can have a roller which is guided in a slotted guide, which can then form on its two inner sides an inclined plane for extending and one for resetting the respective sealing strip.

[0031] In order to ensure particularly uniform and good mobility of the respective sealing strip, one design variant can provide for two or more deflection devices to be assigned to one or more of the sealing strips.

[0032] Alternatively, it can also be provided that the respective deflection device has one or more deflection levers.

[0033] It can be provided that the one or more gear elements, via which the drive means is coupled to at least one of the drive rods, comprise a rack section and one or more gears.

[0034] According to an advantageous further embodiment, it can be provided that the sealing strips and preferably also the drive mechanism and the corner deflection devices are arranged completely concealed in the rebate between the frame and the sliding sash, at least when the sliding sash is closed, so that they do not impair the overall visual impression.

[0035] In a further development, at least one locking device with a movable bolt can be provided to lock the sliding sash in the gap-sealing position, as this can easily increase burglary security. Since the sliding sash can be pushed open from the closed position against the friction of the sealing strips without releasing the sealing strips, or only with great difficulty, this provides a relatively high level of basic security against attempted burglaries.

[0036] It can be provided that this latch is also moved via the drive means, e.g., via a gear connection or a gear mechanism. The latter can be designed in various ways and, for example, according to one possible embodiment, can comprise one or more gears.

[0037] According to an advantageous variant, it can be provided, for example, that the bolt is designed as a rotary bolt which, in one rotary position, engages behind a striking plate on the sliding sash in such a way that the sliding sash cannot be moved, and which, in another position, does not engage behind the striking plate, so that the sliding sash can be moved.

[0038] The sliding sash can be opened and closed manually, for example, using a handle. Alternatively, it can also be designed to be opened and closed by an electric motor.

[0039] Further advantageous embodiments can be found in the remaining subclaims. BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF PREFERRED EMBODIMENTS

[0041] In Figure 1 A sliding wall is shown. For the purposes of this document, the term "sliding wall" particularly includes sliding doors and sliding windows of various types.

[0042] The sliding wall 1 has a frame 2 in the manner of a surround and at least one sliding sash 3 slidably guided in the frame. The frame 2 is designed as a circumferential frame. The sliding sash 3 is movable in the frame 2 or in the surround between a closed position (which is shown in Fig. 1 is shown) and an open position. The sliding sash 3 can preferably be locked in the closed position.

[0043] In the lower area, the frame 2 can be designed to be inserted into a recess in a floor.

[0044] In addition to the sliding sliding sash 3, the sliding wall 1 can have at least one further sliding sash and / or a fixed glazing. The sliding sash 2 is then pushed in front of the fixed glazing when opened (in Fig. 1ato the right). The sliding sash 3 preferably has a surrounding sash frame 301 and a surface element 302 (see Fig. 3a ), which can be designed, for example, as an insulating glass pane. Such a surface element 302 extends in a main surface plane. (in Fig. 1 the X / Y plane).

[0045] The sliding sash 3 engages with one or more of its edges - here with the sash frame 301 - in a lower, here horizontally running first receiving and guide channel 4 of the frame or the frame 2. It can be - see Fig. 2 - be mounted with a lower rail-like support 201 on rollers 202 or the like.

[0046] Alternatively, the sliding sash 3 itself can also have rollers, for example, on its underside, and be mounted in the frame 2 for rolling opening and closing (not shown). For purely exemplary purposes, reference is made to the prior art mentioned above.

[0047] The sliding sash 3 can further engage on its other sides in at least one or more further receiving and sliding channels 4. These further receiving and sliding channels can comprise a second, here horizontally extending upper receiving and guiding channel 4 ( Fig. 11b ) and preferably at least one third receiving and guiding channel 4 ( Fig. 3 ). In this vertical receiving and guide channel 4 (left edge of the sliding wall in Fig. 1a) the sliding sash only engages in the closed position and during the initial movement when opening or at the end when closing, but in the horizontally running receiving and guide channels 4 in the closed position, then during the entire opening process and also in the maximum achievable open position. The structure of such a sliding wall is generally known to those skilled in the art and is therefore not shown in every detail here. A further receiving and guide channel 4 can also be formed in the area of ​​the fixed glazing, which extends vertically between a frame profile of the fixed glazing and possibly an outer cover, through which the sliding sash is pushed when opening and closing.

[0048] At least in the closed position, a gap S is formed between the at least one or more, in particular all, receiving and guide channels 4 and the peripheral edge of the sliding sash 3 between the sash frame 301 and the frame 2. It is necessary to seal this gap S completely or at least partially, at least in the closed position ( Fig. 3a, 3b ).

[0049] This sealing on the respective edge side should preferably be achieved with two sealing strips 5, 6, which are arranged on the inner edges of the sliding channel 4 of the frame 2, which protrude in the opposite direction from the frame 2 inwards in the direction of the sliding sash 3 and which accommodate the peripheral edge of the sliding sash 3, in particular a sash frame section of a sash frame 301 of the sliding sash 3, between them ( Fig. 2 , 3a, 3b). The sealing strips 5, 6 can be aligned substantially perpendicular to the main plane of the sliding sash 3, which means that they are preferably fixed to the frame 2 with a foot on the side facing away from the sliding sash 3 and protrude with a sealing side in the direction of the sash.

[0050] It is known from the prior art to design both sealing strips 5, 6 as brush seals for this purpose, which ensures a relatively good mobility of the sliding sash but a less optimal sealing effect in the closed position.

[0051] According to the invention, neither or only one of the two—here, the sealing strip 6—is designed as a brush seal or as a combination of a brush seal and an elastomer seal. The sealing strip 6 could alternatively be constructed differently, but it should allow the sliding sash to slide relative to the sealing strip 6 when opened. Preferably, the sealing strip 6 rests against the sliding sash 3 in the closed state, preferably against the sash frame 301 of the sliding sash 3.

[0052] It is also known to design one or both of the sealing strips 5, 6 as hydraulically or pneumatically inflatable sealing strips, so that their cross-section can be increased and reduced again for sealing purposes, which can certainly ensure good sealing, but requires the provision of an appropriate hydraulic or pneumatic supply.

[0053] The invention therefore takes a different approach.

[0054] According to the invention, a drive device, in particular with a drive mechanism and a drive means, is assigned to at least one or at least the sealing strips 5, 6. With the drive mechanism, the respective sealing strip 5 is preferably movable as a whole relative to the sliding sash, with the movement of the movable sealing strip 5 occurring perpendicularly or substantially perpendicularly to the main plane (X / Y plane) of the sliding sash 3.

[0055] "Substantially perpendicular" to the main plane of the sliding sash 3 means that the direction of movement of the sealing strip 5 has at least one movement component perpendicular to the main plane of the sliding sash 3, with which the width of the gap S can be varied within its range and the gap S can be closed. "Perpendicular" means that the entire sealing strip 5 or at least parts thereof can be moved perpendicular to the main plane of the sliding sash, i.e., can be moved perpendicular to the sliding direction of the sliding sash.

[0056] In Fig. 2 The main plane of the sliding sash 3 extends in the X-direction to the drawing plane. Fig. 1a The main plane is also the X / Y plane. The movement of the sealing strip 5 then occurs in a Cartesian coordinate system X, Y, and Z in and against the Z direction.

[0057] The sealing strip 5 is thus between a gap opening position I ( Fig. 3a) for moving the sash into an open position and from there back into the closed position and a gap sealing position II for sealing the sliding sash 3 in the closed position ( Fig. 3b ).

[0058] In the gap-opening position I, an open gap S is formed between the sealing strip 5 and the sliding sash 3. A corresponding gap preferably also forms between the sealing strip 6 and the sliding sash 3. This allows the sliding sash 3 to be easily moved into its open position and back into the closed position.

[0059] In the gap sealing position II, however, the sealing strip 5 has been moved and pressed laterally perpendicular to the main plane of the sash against the sliding sash 3 ( Fig. 3b). In this position, the gap S is closed, and the sealing strip 5 may even exert slight pressure on the sliding sash 3, pressing it firmly against the sealing strip 6 on the opposite side of the sliding sash 3. The additional sealing strip 6 may, for example, be designed as a fixed brush seal and / or elastomer seal, which is fixed to the inside of the frame and protrudes from the frame in the direction of the sliding sash 3. The sealing strip 5, on the other hand, may be designed as an elastomer seal or the like, which tightly closes the gap.

[0060] The friction between the sealing strip 5 and the sash frame 3 is very high in this state. However, before the sliding sash 3 opens, the sealing strip 5 is moved back to the gap-opening position I. Only then is the sliding sash 3 opened.

[0061] Preferably, the sealing strip 5 is thus movable as a whole perpendicular to the main plane of the sash and perpendicular to the sliding direction of the sliding sash 3 with the drive mechanism 7. This drive mechanism is not designed as a pneumatic system for inflating the sealing strip 5.

[0062] The drive mechanism 7 can be implemented in various ways.

[0063] Thus, it can be provided that the respective movable sealing strip 5 has a sealing profile 51 which is made of at least one sealing material such as an elastomer or the like ( Fig. 3b ). This sealing material can be secured to a support strip 52, preferably made of plastic and / or metal. The sealing profile 51 and the receiving strip 52 then jointly form the movable sealing strip 5.

[0064] The sealing profile 51 may have a base 511, at least one sealing bead 512, and at least one hollow chamber 513. It may be made of one or more materials.

[0065] According to a variant, the sealing profile can be fixed with a locking foot 511 in a receiving groove 521 of the support strip 52.

[0066] The support strip 52 is in turn slidably guided in a sliding groove 91 of the frame 2 (e.g., on a separate retaining strip 9 of the frame 2). This sliding groove 91 is perpendicular to the sliding sash 3 and open toward the sliding sash 3. The sealing profile 51 protrudes from the sliding groove 91 toward the sliding sash 3, at least in the gap-closed position II and touches it. In the gap-open position I, it is preferably retracted further into the sliding groove 91.

[0067] The sliding groove 91 can be formed directly in a frame profile 200 of the frame 2 or in an abutment and holding profile 9 that can be attached to a frame profile 200 (see Fig. 2 as well as 3a and 3b but also Fig. 4 ).

[0068] In order to move the sealing strip 5, the drive mechanism 7 can have a drive rod 71 arranged parallel to the sealing strip 5 and displaceable parallel relative thereto ( Fig. 4 ). Between the sealing strip 5 and the drive rod 71, deflection means 72 of the drive mechanism are also provided in order to convert a movement of the drive rod 71 parallel to the sealing strip 5 into a movement of the sealing strip 5 perpendicular to the direction of movement of the drive rod 71.

[0069] The deflection means 72 can be designed in various ways.

[0070] So you can - see Fig. 4- On the side of the support strip 52 facing away from the sealing profile 51, inclined ramps 721 may be arranged as deflection means 72, and corresponding rollers 722 may also be arranged on the receiving strip 52. These rollers 722 can roll along the ramps 721.

[0071] However, the arrangement can also be reversed. In this case, rollers 722 are arranged on the support bar 52, and ramps 721 are formed on the drive rod 71.

[0072] An abutment and retaining profile 9 can be provided as an abutment for the drive mechanism 7. This can form part of the frame 2. It can be formed integrally with the frame or fixed to it ( Fig. 3a, b , 4 ). The abutment and retaining profile 9 is designed like a rail and has various functional areas. The abutment and retaining profile can be made of plastic or metal, particularly light metal, for example.

[0073] The abutment and retaining profile 9 is here a separate element from the frame 2, preferably attachable to the frame, e.g., to a fastening groove 92. Alternatively, it can also be designed directly as a single piece with the frame 2 (not shown). The abutment and retaining profile 9 can itself be designed as a single piece or can also be assembled from individual profiles or the like.

[0074] The fastening groove 92 can be designed to be placed on a web 204 of the frame ( Fig. 3a ) to be secured there by clamping and / or locking. This fastening method is simple, but should only be understood as an example. The fastening of the abutment rail 9 to the frame 2 could also be done in a different way, for example, the other way around (groove on the frame and web on the abutment and retaining profile 9).

[0075] The functional contours of the abutment and retaining profile 9 preferably extend over the entire length of the respective side of the enclosure 2. The Fig. 3a and 3b show or illustrate a section of this element.

[0076] The abutment and retaining profile 9 has, as a further functional contour, the sliding groove 91 (a type of guide groove) for at least partially accommodating and guiding the sealing strip 5 during its movements. The sealing strip 5, in particular its support strip 52, is slidably guided in the sliding groove 91.

[0077] The sliding groove 91 is preferably open toward the edge of the sliding sash. It is oriented such that the support strip 52 can be moved within it perpendicular to the main plane of the sliding sash 3.

[0078] In this way, the sealing strip 5 can be placed against the sliding sash 3 and moved away from it again in order to open and close the gap S.

[0079] The ramps 721, on the side of the support strip 52 facing away from the sealing profile 51, preferably protrude outwardly, either entirely or in sections, through openings 93 in the abutment rail 9. They can then rest against the rollers 722 of the drive rod 7. These ramps can be designed as a separate component attached to the respective drive rod 71.

[0080] It can then further advantageously be provided that the drive rod 71 is movably mounted on the abutment and holding profile 9. Thus, the drive rod 71 can be received in an undercut sliding groove 94 of the abutment and holding profile 9. The drive rod 71 is held on the abutment profile 9 in such a way that rollers 722 rotatably mounted on / in the drive rod 71 can roll along the ramps 721.

[0081] If the rollers 722 run on the ramps 721 during the linear movement of the respective drive rod 71, the ramps 721 and thus the entire support strip 52 with the sealing profile 51 in the sliding groove 91 for the sealing profile 5 are moved in the direction of the sliding leaf 3 until the gap S closes and the gap-closed position II of the Fig. 3b is reached.

[0082] In this way or via another drive mechanism, a certain pressure can be applied or exerted on the sealing profile 51 or on the edge of the sliding sash 3 via the sealing strip 5, which results in a particularly high level of tightness.

[0083] It may be provided to provide a return spring that ensures a return movement of the sealing strip 5 when the rollers 722 are rolled back on the ramps 721. In this way, the ramps 721 are "freed." The return spring then ensures a return of the sealing strip 5 in order to reopen the gap S.

[0084] According to a particularly simple variant, the return spring is a leaf spring. Furthermore, it can be provided in a particularly simple manner that the respective ramp 721 itself is designed as a leaf spring, which, for example, is fixed at one of its ends to the support bar 52 and at another end to the abutment rail / bar 9. Then, the ramps 721 themselves can also form the respective return spring.

[0085] The abutment rail 9 effectively absorbs and supports the forces generated when the drive rod 7 and the sealing strip 5 move. This allows the sealing strip 5 to move safely and smoothly in its sliding groove 91 perpendicular to the main plane of the sliding sash 3.

[0086] In this embodiment, the sealing strip 5 is extended against the spring force of the return spring. However, the sealing strip 5 is then advantageously returned by spring force.

[0087] In one variant, the ramps 721 can also form part of a slide track 723 in which the roller 722 can roll (see Fig. 5a-c ).

[0088] The slide track 723 then preferably has ramps 721 oriented in opposite directions on both sides. Thus, by moving the drive rod 71, the sealing strip 5 can be moved in both of its possible directions of movement without a return spring. The force when advancing the sealing strip 5 or extending the sealing strip 5 is thus reduced. Therefore, an additional retraction force must also be applied when retracting or retracting the sealing strip 5 (see Fig. 5a and Fig. 6a - d ).

[0089] The slide track 723 can be in a plate 724 ( Fig. 5c ) which is attached to the rear side of the support strip 52 facing away from the sealing profile 51 ( Fig. 5b ), for example by screwing.

[0090] It is advantageous to arrange at least one of the movable sealing strips 5 not only on one side of the frame 2, but on two, three or more sides (e.g. horizontally above and below and vertically) of the frame.

[0091] In this way, a type of "sealing frame" can even be constructed from sealing strips 5. This sealing frame can be formed entirely or essentially entirely around the sliding sash 3.

[0092] Then, preferably, the entire sealing frame is moved synchronously, i.e., the entire frame can preferably be extended synchronously from the sliding grooves 91, particularly when the sliding sash 3 has been moved into the closed position. The sealing frame is pressed against the sliding sash 3 and presses it slightly against the opposite sealing strip 6. For this purpose, the sliding sash 3 is preferably mounted so as to be displaceable with play relative to the frame or the surround 2 that a slight movement perpendicular to the surround 2 can take place in the receiving and guide channel 4 of the frame 2 in order to seal the gap S particularly securely. In this way, when the sliding sash 3 is in the closed position, particularly good sealing can be achieved to prevent sound from passing through the gap S. Furthermore, very good resistance to driving rain is achieved.

[0093] In the area of ​​the fixed glazing, its vertical frame beam or its vertical frame profile 200 can be used to support the sealing frame ( Fig. 13 ). Furthermore, a further vertical frame beam 200 (not shown here) can be provided on the outside of the frame, which has a sealing strip 6, so that support is also provided in the area of ​​this vertical frame profile in the area of ​​the fixed glazing. The sliding sash 3 then also engages in a type of receiving and guide channel 4, at least in the closed position.

[0094] The sealing strips 5 of the sealing frame can be completely or completely sealed on one or both vertical sides and on both horizontal sides according to the type of Fig. 2 , 3a , 3b or 11 be constructed.

[0095] It is then advantageous to couple the drive rods 71 ​​on the different sides, e.g., via corner deflection devices 77, as are generally known from window construction for coupling drive rods at corners. For example, flexible, bendable, and corner-slidable thin sheet metal strips 771, which couple two adjacent drive rods 71 ​​at a corner, are well suited. A drive is then only required on one of the drive rods 771 ( Fig. 7a, b ). The other drive rod is taken along.

[0096] To move the drive rod 71, this or one of the drive rods of the sealing frame can have a drive contour. This drive contour can be designed, for example, as a rack section 73. It is then advantageous if this rack section 73 meshes with at least one gear 74 that is mounted on the frame 2. The gear 74 can be directly ( Fig. 8a, 8b , 9a-9c , b) or via further interposed gear wheels by means of a handle 75. The handle 75 can be a pivoting handle, which can be arranged on the frame 2, for example, pivotable by 180° (see also Fig. 1a ) and which is designed to rotate the gear 74. If several gears are connected between the handle 75 and the one or more rack sections 73, a higher gear ratio can be realized if necessary in order to reduce the manual force for pressing and / or releasing the sealing frame or to adjust it appropriately. One or two rack sections 73 can also engage the gear 74 on opposite sides, which are then each connected in opposite directions to drive rods 71, so that a drive of two drive rods 71 ​​in two directions can be realized.

[0097] Alternatively, the gear 74 can be moved directly or via further intermediate gears by means of a controllable motor in / or on the handle (not shown here).

[0098] An electric motor 76 can then alternatively act directly on the drive rod 71 like a type of "electric cylinder" via a spindle drive, one element of which is coupled to the drive rod 71 via a lever or the like, in order to move the latter linearly back and forth when the spindle is extended and retracted.

[0099] The electric motor 76 can optionally be completely concealed in one of the receiving and guide channels 4, so that it is preferably not visible from the outside when the sliding sash 3 is closed. For this purpose, its cross-section is preferably so small that it can be completely accommodated by the guide channel. The use of a pneumatic cylinder instead of an electric cylinder is also conceivable.

[0100] The first variant, with a manual drive via a pivoting lever, is particularly simple and requires only mechanical components, but no pneumatic or electrical components. The second variant, with an electric motor, allows motorized operation, preferably via a control unit to which the electric motor is operatively connected.

[0101] Fig. 14a and billustrate how, with a latch 80, at least one point on the sash can be blocked against displacement in the gap-sealing position, thus providing additional security against the sliding sash 3 being accidentally pushed open. The latch 80 can be extended via a separate deflection mechanism and preferably engages in or behind an abutment 81 on the sash 3, which can be formed, for example, on the sash frame 301, e.g., on its upper side. The deflection mechanism can preferably be arranged on a different side of this drive rod 7 than the deflection mechanism for moving the sealing strip 5.

[0102] The Fig. 10a) to c) disclose a variant of this design. Here, the drive means—here, the handle 75—is coupled to a rotatable latch 79 via a gear—here, for example, consisting of further gears 741, 742, 782, of which gear 741 can be arranged with gear 74 on a shaft or pin.

[0103] This rotatable bolt 79 can have a non-circular shape at its end or a non-circular head 82. In this case, the head 82 can, when the sliding sash 3 is closed, engage in an opening 84 of a strike plate 83 on the sliding sash 3, here on the vertical sash frame beam (in Fig. 1a far left). In this position, it can be rotated using the drive mechanism, in particular by 90°.

[0104] The opening 84 and the head 82 are coordinated such that the bolt does not inhibit the movement of the sliding sash in a first rotational position, since it is aligned such that it does not engage behind the strike plate, so that the latter can be moved with the sliding sash over the head 82. In the other rotational position, however, it engages behind the strike plate, so that the movement of the sliding sash 3 is blocked - particularly for burglar protection.
