EP2426306B1 - Sliding unit - Google Patents

Description

The invention relates to a sliding unit, in particular a door or window unit, with an opening of an outer skin of a building at least partially delimiting frame and with at least one movably held on the frame and there displaceable element, between an opening covering the closed position and the opening At least partially releasing open position with a parallel to the building skin stretched movement component is displaced, according to the preamble of claim 1 or claim 2.

The term sliding unit refers to a complete structural unit or a segment of an external building skin, for example in the roof or the façade, this structural unit comprising a displaceable element, for example a door or a window, and a frame bordering it in whole or in part. The displaceable element may for example be a sliding door or a roof element in a conservatory construction be, or even a door, window or roof window element, which is arranged in a non-configured as a conservatory building section, for example, surrounded by masonry or by a conventional roofing. The surrounding frame can be firmly connected to the environment, for example an external building skin.

The displaceable element is hereinafter referred to partially as a window, but may also be a door, an escape hatch or the like and is not necessarily transparent

From the DE 42 29 661 A1 and the EP 1126093 B1 Each brush seals are known to seal a movable window against a fixed frame. However, the tightness with respect to the surfaces swept by the bristles, both against moisture and against drafts - and thus also the thermal seal - is limited. In addition, the brushes tend to fouling and fraying in continuous operation, so that they must be replaced frequently to obtain a good function. The comparatively poor sealing effect is often accepted, since otherwise it is assumed that other types of seals have too high a sliding resistance, which would affect the one hand, the operation of the movable window or require an undesirably strong and therefore large drive motor and correspondingly large-sized transmission elements and would lead to premature wear of the sealing elements.

The EP 1 510 647 A1 shows an inherently flexible flat unit, which can cause no tightness due to their rollo-like training and therefore even no sealing lines Has or requires frame parts. In one embodiment, a zipper is provided for connecting the pull rope with the fabric of the blind unit. However, such a zipper itself is not sealing, but serves only for mechanical connection to allow about a longitudinal guide of the roll edge on the outer frame part. Especially in the middle, between roller blind and frame free area of the band this is interrupted by joints and therefore particularly leaky there.

The DE 20 2007 006 127 U1 is intended for sliding body, which are perpendicular to a lower surface against which to be sealed, stand and run there. The conditions are therefore very different than in the problem underlying the invention. A brush seal or two wings apart can not achieve the sealing effect required in the outdoor area. The DE 20 2007 006 127 Ul describes a sliding unit having the features of the preamble of claim 1 and the preamble of claim 2.

The invention is based on the problem to improve a sliding unit of a building exterior skin to the effect that the best possible and also in continuous operation inexpensive seal between the movable element and the frame is made possible without great sliding resistance.

The invention solves this problem by a sliding unit with the features of claim 1 or claim 2, which can be realized individually or in combination with each other. With regard to advantageous embodiments, reference is made to the dependent claims 3 to 16.

Due to the invention is in the embodiment of claim 1, a cuboid sliding unit with an in the installed position with respect to the building outer skin outwardly facing outer surface and two angled thereto Created side surfaces, wherein at least the outer surface and / or the side surfaces are assigned on both sides sealing lines for sealing the side surface relative to the fixed frame, characterized in that between the displaceable element and the frame at least one sealing line with a flexible, deformable and both on the Frame as well as on the displaceable element at least guided tape is arranged, a seal is provided, which can be compared to the frame and the displaceable element of similar and compared to a pure contact system increased tightness and due to the deformable band structure allows a significant tolerance compensation without It would thereby increase the sliding resistance.

In training according to claim 2, characterized in that the band between the displaceable element and the frame on the frame or the displaceable element is held in the mounted position and guided relative to the respective other component parallel to the direction of movement of the movable element, ensures that the mobility of the displaceable element is unimpaired and the sealing line still retains a unique positional assignment in each state of movement of the movable element by their fixation. In particular, while the band can be held firmly on the frame, for example, characterized in that the band is first pulled longitudinally into a corresponding rail-like receptacle of the frame and then a cap is placed on the recording. Further fixations, such as nails, adhesives or the like, are then unnecessary. The displaceable element is then relatively displaceable relative to the firmly held band.

In this case, the at least one band is designed to be thickened at its two outer edges in the transverse direction with respect to its transversely middle region. With the help of this Thickening, the tape can be held securely on both sides in or on guide rails.

Here, a guide rail is provided both on the displaceable part and on the frame in each case for each band to be held. In this case, the band can be displaceable only in one of the guide rails parallel to its extension and fixed in the other.

In this case, in a lying below an outer frame leg window part or similar displaceable element, the band on the window-side guide rail, such as a screw in the end, easily fixed and be displaced with its opposite transverse edge relative to the frame-side guide rail, so that even in the open position of displaceable element the band is always outwardly protected under and / or behind the movable element runs.

If, advantageously, the band can be mounted on and detachable from the frame parallel to the direction of movement of the displaceable component on the frame and on the displaceable element, this results in a simple initial assembly of the band. Similarly, a later exchange is easily possible.

If the band is axially symmetric or point-symmetrical with respect to a plane or longitudinally cutting through the belt in the longitudinal direction, the mounting direction of the belt is irrelevant. It does not matter which side is assigned to the frame and which to the movable element.

The marginal thickenings may be, for example, kederartig. In particular, at least one of the thickened regions is formed by a row of teeth of hook parts of a zipper for inexpensive use of cut-off bands.

In particular, both thickened regions associated with the transverse edges may also be formed by rows of teeth of hook portions of a zipper, thereby providing equal conditions to the frame and displaceable portion and stable conditions in the guide rails.

It is particularly favorable for a tensile strength of the band, when the band is woven or knitted textile in its transverse central region and the hook parts of the row of teeth (s) are enclosed therein in mesh.

In particular, the band may be or at least comprise a prefastened slide fastener tape, since such a slide fastener tape has high mechanical stability and is manufactured on an industrial scale as demand-adapted to each window dimension by cutting-length adaptable tape.

Since such a zipper tape conventionally comprises only on one side hook parts, according to the invention either a separate zipper tape with arranged at its two transverse edges hook parts of zippers may be formed, or the band may consist of two interconnected zipper tapes, each having arranged on a transverse edge hook parts of zippers be formed.

These are then, for example glued together and / or welded.

Nevertheless, advantageously, the guide rail of the frame and the displaceable element can be designed identically, so that no different rails must be stored and both the logistical effort and the assembly costs are low.

Each of the guide rails can each enclose a thickened edge region of the band in a receiving channel, which for this purpose is, for example, C-shaped.

Despite the secure enclosure, the guide rail may for example consist of plastic and be so flexible that the tape can be clipped into the respective guide rail. An insertion is possible even with rigid training of the guide rails.

Since the displaceable element has a substantially parallelepiped shape with an outer surface facing outwards in relation to the outer skin of the building and angled sides on both sides, the outer surface and also the side surfaces are each assigned sealing lines on both sides for sealing the side surface relative to the fixed frame.

At least two sealing lines not only a good seal is achieved.

If at least two sealing lines parallel to each other and spaced from each other to seal the side surfaces the fixed frame are arranged, the independence of the sealing of an outer or inner surface of the window od. Like. Improved. It not only gives good protection against the ingress of moisture, but also a good thermal insulation.

If a first sealing line with lip seal between a the outer surface of the movable element edge outside cross-leg of the frame and the outer surface of the displaceable element is located, a Windstop is already far outside and reduces the penetration of cold air into the side regions of the movable element.

The thermal insulation is particularly good when there are at least three seal lines extended with components in the direction of movement.

Conveniently, at least one sealing line comprises a profile or lip seal, the at least one lip or rubber-elastic deformable profile with a longitudinal component in the direction of movement and especially in a lip seal with a transverse component transverse to the direction of movement on the displaceable element or on the frame, wherein the transverse component has an orientation pointing in the direction of the transverse center of the displaceable element orientation. As a result, a kind of channel is created, which receives the incident on the outer surface liquid and can dissipate in an oblique or vertical mounting position down, without that they could penetrate laterally into the frame.

In addition, it is favorable if between two or more of the sealing lines in each case the distance between the frame and the displaceable element at least largely bridging Heat insulation strips, such as a foam material, are arranged.

In particular, in an inclined position of the sliding unit below the side surfaces still an upwardly open drive frame may be provided, the drive elements, such as a spindle and drive motors, absorbs and may be derived as the last security possibly penetrating water down.

Windows according to the invention can be designed to be very large in area and, for example, have a window area of several square meters, whereby the arrangement of the sealing lines nevertheless provides good moisture and thermal insulation.

In particular, the sliding unit has a window which has a thermally separated window frame and a thermally insulating filling held therein.

Further advantages and features of the invention will become apparent from the drawing illustrated and described below embodiments of the subject invention.

Fig. 11

a similar view as FIG. 10 , However, an alternative embodiment which is axially symmetrical and also exemplarily on both sides zangeartige heads for grasping rails has.

The sliding unit shown in the drawing is designated overall by 1. It is arranged in an outer building skin and has laterally projecting flange portions 30 for connection to this outer skin. The sliding unit 1 can thus be arranged in an opening of the outer skin and form, for example, a vertical or oblique window or a door or escape hatch. For example, such a sliding unit obliquely in the roof of a conservatory or even within an otherwise designed building roof, z. B. surrounded by a conventional roofing, are arranged.

In the illustrated embodiment, the sliding unit 1 has an opening at least partially surrounding the frame 2, which is defined on the flange 30 on the surrounding outer skin and therefore can itself also predominantly lie in the opening. Here, the frame 2 in plan view is approximately C-shaped and comprises three mutually perpendicular sections 3, 4, namely an upper - yoke-like - section 3 and two mutually parallel, thereof with a component downwardly facing side legs 4, so that the frame 2 at its lower end here, the upper portion 3 opposite, leaving an opening 5 free.

Notwithstanding the illustrated embodiment, the sliding unit 1 can also be configured as a laterally or upwardly opening window or as a laterally or upwardly opening door, so that then the opening of the frame would be laterally or in the upper region. The frame may also be circumferentially closed, in which case the frame length would be so great that a displacement path for a displaceable in the frame 2 held element 6 would be provided in the frame.

Here, the displaceably held element 6 is formed as a window and occurs during its displacement in the opening direction partially through the opening 5 to the outside and over the length of the side legs 4 also ( Fig. 1 ). The side legs 4 can be kept visually elegant so short that they end in alignment with the displaceable element 6 in its closed position.

The displaceably mounted element 6 is therefore displaceable between a closed position covering the aperture and an open position which at least partially releases the aperture with a movement component 31 extending parallel to the frame plane. It may itself comprise a completely or partially encircling window frame 7 and a filling 8, for example a double or triple glazing.

The displaceable element 6 is formed as a relatively flat and substantially cuboidal body and has in the installed position with respect to the building outer skin outwardly facing outer surface 35 and on both sides angled to this standing side surfaces 36. The thickness of the element 6 can vary considerably - depending on the purpose.

Between the displaceable element 6 and the frame 2, at least one sealing line 9, 10, 11, 12, 13, 14, 15, 16 extending at least in regions parallel to the displacement direction of the displaceable element is arranged. At least one of the sealing lines 9, 10, 11, 12, 13 in this case comprises a flexible, deformable and at least both guided on the frame 2 and on the displaceable element 6 - if not even fixed - band 17th

This in FIG. 6 By way of example and in a not yet mounted, randomly positioned position illustrated band 17 has a large extent in the longitudinal direction L with respect to its transverse direction Q and at its two transverse outer edges R1, R2 executed opposite its transversely Q central region M thickened.

It is in the embodiment according to FIG. 6 at least one of the thickened regions, here both edge regions R1, R2, formed by a row Z of hook portions 18 of a zipper. These hook parts can be made of different materials, such as metal or plastic.

In the execution after FIG. 10 , which shows a mounted band 17, however, the edge regions R1, R2 are formed as thickened piping, the stiffening in the interior of each one Silicone or plastic cord or the like may contain.

Also, a rubbery material, which is material-uniform overall including both end portions R1, R2 and may be extruded, for example, may alternatively be used.

The band 17 according to FIG. 6 is woven or knitted in its transversely Q central region M textile such that the hook portions 18 of the row (s) Z are enclosed therein in mesh and thus held securely and permanently.

In particular, the tape 17 shown there is a prefabricated zipper tape or at least includes this. This makes an industrial and very inexpensive mass production possible. The zipper tape can be cut to length, for example, on site and in adaptation to a variety of window sizes.

It is either a preparation of a band 17 of a single zipper tape with arranged at its two transverse edges R1, R2 hook parts 18 of zippers possible, which are made extra for this purpose. Alternatively, a band 17 of two interconnected zipper tapes 17a, 17b, each having on only one transverse edge R1 or R2 hook portions 18 of zippers, be formed. The two bands 17a, 17b can then be placed on each other in a reverse orientation and welded together and / or glued.

Likewise, the alternative band 17 after FIG. 10 be formed of two interconnected subbands 17a, 17b. The two bands 17a, 17b can also be placed on each other in reverse orientation and welded together and / or glued together, so that there is a point-symmetrical about the longitudinal straight line 37.

Alternatively, an axially symmetric structure to a mirror plane 38, as in FIG. 8 and FIG. 11 , possible.

In both cases, the installation direction of the belt 17 does not matter, d. That is, each end portion R1, R2 can be optionally assigned to the frame 2 or the displaceable unit 6, which facilitates assembly.

Here, the assembly is carried out so that the band 17 is held on the frame 2 or the displaceable element 6 in the mounted position and guided relative to the other component, ie the displaceable element 6 or the frame 2 parallel to the direction of movement of the displaceable element 6. In particular, by a closure cap or the like, the band 17 is held on the frame 2, so that the displaceable element can be opened or closed with respect to the held band with a relative movement.

For its assembly, the band 17 can be mounted parallel to the direction of movement of the displaceable component 6 to the frame 2 and to the displaceable element 6, for example, be fed into a guide rail. Likewise, disassembly in the opposite direction is easily possible. As a result, a wear-related replacement after a few years is very easy.

In FIG. 8 a variant is drawn in which the bands 17a, 17b outside the peripheral thickening, for example, the hook parts 18, are not connected to each other and leave a filled with an insulating material 26 cavity between them to improve the thermal insulation. The insulation may be formed approximately from a foam material.

Other edge thickenings, such as piping, are possible and in FIG. 10 shown. In FIG. 11 In addition, a reverse variant is indicated, in the dimensionally stable outer edges R1, R2 of the band 17 engage around complementary pliers like a guide.

The band 17 can also consist of a flame-retardant material, such as a metallic fabric, or have a fire-resistant coating, so that very advantageously the invention can also be used for fire and / or smoke protection, such as public buildings or in sensitive areas. The displaceable elements 6 need not be transparent.

Both on the displaceable part 6 and on the frame 2, a guide rail 19 is provided in each case for each band 17 to be held, a sealing line with band seal 9, 10, 11, 12, 13 formed therewith. This is in FIG. 7 only schematically shown in cross section.

The guide rail 19 may be formed, for example, as extruded or extruded metal or plastic and also be cut to length as needed. It comprises a receiving channel 20 for the thickening of the belt 17. The receiving channel 20 may be formed so that a Guide rail 19 in each case a thickened edge region R1, R2 of the band 17 in this receiving channel 20 borders. The receiving channel 20 may be formed for this purpose, for example, in cross-section C-shaped. On its rear side 21, the guide rail 19 may be firmly connected to the frame 2 or the displaceable element 6, for example glued and / or screwed. In this case, the band 17 can be clipped into the respective guide rail 19, at a not sufficiently flexible design of the guide rail 19 also only be inserted. In FIG. 11 the conditions are reversed accordingly.

In the receiving channel, the edge-side thickening of the belt 17 without further measures, such as a final fixation, easily displaced with little resistance.

As in FIG. 9 becomes clear, a plurality of guide rails 19 can be arranged one above the other on the side 36 and / or on the front side 35. The number depends very much on the thickness of the displaceable element 6. Here, five receiving channels 20 are provided both on the frame 2 and on the displaceable element 6, which are opposite each other at the same height. In all of these guide rails 19 17 belts can be retracted due to the low sliding resistance and inexpensive installation, which are all at the same time moved, for example, with respect to the frame-side guide rails 19 at the opening or closing of the movable element, but are fixed to the window 6.

Due to the high number of sealing strips 17, both a good thermal insulation as well as a good smoke and / or fire protection can be achieved.

It is possible that the guide rail 19 of the frame 2 and the displaceable element 6 are formed similar, so that the logistical effort is minimized.

In the FIGS. 2 to 5 For example, exemplary cross-sectional views of an assembled state of seal lines with tape seals 9, 10, 11, 12, 13 are shown. In this case, the band 17 may be fixed to one of the two guide rails 19, here on the one associated with the frame 2. Compared to the other guide rail 19 which is associated with the displaceable element 6, the band 17 rimmed there remains parallel to the extension of the guide rail 19 displaced. The window 6 can thereby postpone, without pulling the band 17. This therefore remains protected in any open position of the frame 2.

The above-described parallelepipedal, displaceable element 6 with an outer surface 35 facing outwards in the installed position with respect to the outer skin of the building and side surfaces 36 angled on both sides can have at least one or advantageously also several sealing lines 9, 10, 11, 12, 13, 14, on each transverse side. 15, 16 to be assigned to seal against the fixed frame 2.

At least two sealing lines, for example 9, 10 as sealing lines with band seals, and 14 as a first sealing line with lip seal are advantageously arranged on each transverse side of the displaceable element 6, such as in FIG FIG. 2 is shown by way of example. The outer first seal line with lip seal 14 or similar non-hydrophilic seal can form an intense protection against the ingress of water and wind, so that the seal lines with band seals 9 and 10 already in a protected area lie. The first sealing line with lip seal 14 is particularly effective against ingress of water, for example, even when cleaning with a hose or even a high-pressure cleaner, which is collected via the channel 24 and discharged downwards, without being able to penetrate further into the interior.

The width of the band 17 may vary, such as in difference between FIG. 2 and FIG. 3 is recognizable. Zipper tapes are produced industrially in various widths from a few millimeters to a few centimeters.

According to the exemplary embodiments, a first sealing line 14 lies below a leg 22 of the frame 2 which engages over the outer surface 35 of the displaceable element 6 on the outside and thus between this leg 22 and the outer surface 35 of the displaceable element 6.

This first seal line with lip seal 14 comprises a rubber elastic lip seal of, for example, a rubber material. Further such sealing lines with lip seals 15 and 16 ( Fig. 3 . Fig. 4 ) can be provided.

In particular, the sealing lines may be barely formed with lip seals such that a respective lip 23 provides an upwardly or to the transverse center 25 open receiving channel 24 for liquid such as rain or condensation water.

In FIG. 3 is a first sealing line with lip seal 14 as in FIG. 2 provided, in addition, a further sealing line with lip seal 15 is arranged with an upwardly open receiving channel on the transverse side 36 of the movable element 6. In addition, on the transverse side 36, a band seal 12 and in the upper Corner region another band seal 11 between the outer surface 35 of the movable element 6 and the side surface of the frame 2 is arranged. Overall, here are four seal lines, so that there is an outstanding protection against cold, drafts and moisture. It is particularly useful here to replace rubber seals with relatively high sliding resistance by sealing lines with tape seals 9, 10, 11, 12, 13, which offer with their easily sliding zipper hooks 18 (even rollers or the like would be possible) only a minimal sliding resistance. The bands 17 may be made of plastic threads or impregnated so that they also do not draw water.

In FIG. 4 is shown as a further increase of the particular thermal seal a version with three rubber-elastic sealing lines with lip seals 14, 15, 16 or similar profile seals and two sealing lines with tape seals 11, 12.

In FIG. 5 is provided in place of the upper sealing line with band seal 11, a sealing line 13 which is between the outer surface 35 of the displaceable element 6 and the cross-leg 22 extends.

All sealing lines 9, 10, 11, 12, 13, 14 15, 16 are arranged parallel to and at a distance from each other for sealing the displaceable element 6 relative to the fixed frame 2.

In addition, between two or more of the sealing lines 9, 10, 11, 12, 13, 14, 15, 16 in each case the distance between the frame 2 and the displaceable element 6 at least largely bridging heat insulation strips - not shown here - be arranged.

In addition, it can be provided that within the frame 2 a plurality of windows 6 are arranged, of which at least one is designed as a movable window 6 in the manner described above and wherein at least two windows 6 are movable relative to each other.

The operation of the window or the like element 6, to move this from its arranged in the frame 2 closed position in an out of the frame 2 through the opening 5 "down" outstanding open position, as well as the return movement motor. For this purpose, at least one electric motor is arranged within the frame 2, for example in the upper section 3. In this arrangement, a problem-free access to the motor is possible when the window 6 is open. On either side of the electric motor extends a shaft which transmits the rotary motion of the motor to an angular gear. This transmits the rotational movement of the shaft on a spindle which is mounted in the lateral portion (side legs) 4 of the frame 2, wherein also in the opposite lateral portion 4, such a spindle is provided, which is also driven by the same electric motor via a shaft and an angle gear is. The provision of two or even four synchronized drives, which are then each very small and can be arranged to save space in the frame 2, is possible. Due to the redundancy, the system can still be moved even if one motor fails or the remaining drives continue to move. This is particularly important for large moving elements 6, such as with edge lengths of two to three meters, important because they often can not be moved by their weight manually otherwise.
