This application is the U.S. national phase of International Application No. PCT/EP2018/077162 filed Oct. 5, 2018 which designated the U.S. and claims priority to DE Patent Application 10 2017 123 074.2 filed Oct. 5, 2017, the entire contents of each of which are hereby incorporated by reference.
The invention relates to an automatic door system, in particular in the form of a sliding door or a telescopic sliding door or a folding door.
Automatic door systems serve to allow and prevent access to particular rooms. The door systems operate automatically; in other words, it is detected by way of sensors whether a person is located in the vicinity, and if detection is successful the passage is opened by displacing the door leaf. Subsequently, the door leaf is held open for a while longer and displaced back into the closed position. The closed position is also important because it prevents the building interior from being excessively heated during high external temperatures in summer and excessively cooled during low external temperatures in winter. The door leaves are therefore often in movement, and the guide rails are exposed to corresponding stress. As well as a displaceable door leaf, there are also stationary leaves or corresponding glass panes. These are also part of the door arrangement, and often use the same mechanical fixing points.
DE 10 2009 058 922 A1 describes a guide for a sliding leaf. For this purpose, exactly one floor rail is provided, and has a groove in which a door leaf engages via a blade on the lower face of said leaf. The door leaf is displaceable with respect to the floor rail. An end cap is placed on one end of the floor rail, and comprises at the floor region a hose connector for connection to a drainage hose. This end cap thus never enters into engagement with the door leaf.
From DE 10 2007 003 904 B4, a door arrangement of this type together with a floor threshold is known. This door arrangement comprises both a displaceable door leaf and a stationary door leaf. A floor threshold comprising a corresponding sealing device ensures that no water can penetrate into the foundation below and that barrier-free passage is nevertheless possible. The floor threshold comprises, on the lower face thereof, corresponding connection means, which are spaced different distances apart in such a way that they can engage selectively in different widening profiles.
A drawback of DE 10 2007 003 904 B4 is that the construction of the door arrangement, in particular as regards the floor rail, is complex, and a change is not possible directly during assembly.
Therefore, the object of the present invention is to provide an automatic door system which, in particular as a result of the floor-side guide rail arrangement thereof, can be constructed as simply as possible and simultaneously exhibits low wear in operation.
The object is achieved by claim 1 for the automatic door system. Advantageous developments of the automatic door system according to the invention are set out in claims 2 to 20.
The automatic door system according to the invention is in particular formed as a sliding door or a telescopic sliding door or a folding door. It comprises at least one first door leaf arrangement that has a first door leaf that can be displaced on a first length sub-stage in the longitudinal direction of the door system. Further, at least one first drive device is provided, which is operatively connected to the at least one first door leaf or the at least one first door leaf device in such a way that the at least one first door leaf is displaceable along the first length sub-stage. Moreover, a floor-side guide rail arrangement is additionally provided, which extends in the longitudinal direction and comprises at least one first floor rail arrangement. The at least one first door leaf of the at least one first door leaf arrangement comprises an engagement element, the engagement element being arranged on the lower face of the at least one first door leaf. The at least one first floor rail arrangement comprises at least one first floor rail and at least one connection and/or functional element. The connection and/or functional element is arranged and/or fixed on an end face of the at least one first floor rail, causing the floor rail to be lengthened in the longitudinal direction. The at least one first floor rail comprises the at least one first guide groove extending in the longitudinal direction. The at least one engagement element of the at least one first door leaf of the at least one first door leaf arrangement dips into the at least one first guide groove, and is guided in the longitudinal direction by the at least one first guide groove. The at least one first floor rail arrangement further comprises at least one second floor rail, which extends in the longitudinal direction. The first and the second floor rail each comprise an upper wall segment and two lateral wall segments, which connect to the upper wall segment and together enclose a cavity extending in the longitudinal direction, the first and/or second floor rail, in cross section, in the peripheral direction:
The use of the at least one connection and/or functional element, which is arranged on an end face of the at least one first floor rail and connected thereto, is particularly advantageous. A connection and/or functional element provides additional functions for the door system. For example, it is thus possible that further functions can be added in a particularly simple manner, while at the same time merely standard floor rails are used. Because the connection and/or functional element lengthens the first floor rail, it is also possible to use, for the first floor rail, lengths that are less than the length of the corresponding first length sub-stage in which the door leaf is displaced. This is particularly advantageous because usually the floor rails are only produced in one length, and the remainders have to be thrown away after cutting to length, since they are simply too short for another installation. By contrast, the connection and/or functional element along with the additional functions thereof can be tested directly in production, and merely remains to be inserted at the assembly site.
In this case, the connection and/or functional element comprises, on the first and second end face, a fixing projection, which engages in the engagement openings of the associated first end faces of the two floor rails, causing the first and second floor rail to be mechanically stably interconnected via the connection and/or functional element. As a result, two floor rails, which may be of different length, can be interconnected. This means that it is also possible to use floor rails that are per se shorter than the first length sub-stage or that are shorter than the extension of the floor-side guide rail arrangement in the longitudinal direction.
In a particularly preferred embodiment, the at least one connection and/or functional element is arranged in the first floor rail arrangement in such a way that, in a closed position of the at least one first door leaf of the at least one first door leaf arrangement, a secondary closing edge of the at least one first door leaf is positioned approximately above the at least one connection and/or functional element. A closed position of this type is adopted for a relatively long time, in particular at night. Since the doorframe and the floor rails consist of metal (in particular aluminium), the high heat transmission resistance due to the connection and/or functional element between the first and second floor rail of the first floor rail arrangement is not spoiled by the two floor rails having direct contact with the lower face of the door leaf, which would then act as a thermal conductor. Instead, in the closed position, the first door leaf only comes to rest on a floor rail and the connection and/or functional element.
In a further preferred configuration, the first guide groove extends from the first floor rail via the connection and/or functional element into (or along) the second floor rail of the first floor rail arrangement.
In an advantageous embodiment of the automatic door system, the at least one connection and/or functional element further comprises a holding device that is formed to hold a door structure such as a doorframe or glass frame. For this purpose, the holding device preferably comprises a holding and positioning projection, which protrudes from the upper wall segment and is formed to hold the door structure. Alternatively, the holding device comprises a holding and positioning opening, which is accessible from the upper wall segment and is formed to receive projections from a lower face of the door structure and thus to hold the door structure.
In this context, it is particularly advantageous that the associated floor rails can be manufactured in a standardised manner and cut to a particular length, special functions merely being taken on by the at least one connection and/or functional element. The connection and/or functional element may also be manufactured in advance, and has standardised dimensions. During installation, the floor rails are cut to the corresponding length and interconnected by way of the connection and/or functional element, which, in this case, also additionally carries the door structure. As a result of the floor rails being correspondingly cut to the appropriate length, the connection and/or functional element is always arranged in the correct position.
In a further preferred embodiment of the automatic door system, the connection and/or functional element further comprises a locking receiving opening, which is formed to receive a locking bolt, which can be extended out from a lower face of the at least one first door leaf of the at least one door leaf arrangement or which is part of a closing cylinder. In this context, it is advantageous that this locking receiving opening can be introduced ex works and if appropriate can further be made reinforced. The floor rails themselves do not have to be post-processed specially, and so they may further very favourably be produced for example as extrusions. They may also be produced as bent and/or rolled parts.
It is further advantageous if the connection and/or functional element further comprises a hook lock as well as a release device. In this context, the hook lock is arranged displaceably (for example rotatably and/or pivotably) in the at least one connection and/or functional element, and can be moved and/or pivoted and/or flapped and/or snapped from a release position, in which the at least one first door leaf of the at least one first door leaf arrangement is displaceable along the longitudinal direction, into a blocking position, in which the at least one door leaf is locked stationary. In the blocking position the hook lock engages in a fixing opening on the lower face of the at least one door leaf, and in the release position it is preferably arranged completely within the connection and/or functional element. The release device is formed to transfer the hook lock from the release position into the blocking position and back. A hook lock of this type ensures that the door leaf cannot simply be pulled away.
The release device is advantageously arranged below the locking receiving opening in the at least one connection and/or functional element. The locking bolt, in the state where it engages in the locking receiving opening, contacts the release device, causing the release device to bring about the displacement of the hook lock from the release position into the blocking position. Preferably, in this case, the connection and/or functional element further comprises an energy store device, in particular in the form of a spring device, which is formed to displace the hook lock from the blocking position into the release position while contact of the release device by the locking bolt remains absent. The locking device is in particular formed in such a way that in the event of a power failure the locking bolt is pulled out of the locking receiving opening, the energy store device simultaneously ensuring that the hook lock is transferred from the blocking position into the release position. In this case, the door can reliably be slid open in the event of a power failure.
In a preferred development, the at least one connection and/or functional element may also have additional functions. Thus, at least one heating element, preferably in the form of a heating wire, may be arranged therein. It is also possible for the at least one first drive device or at least part of the at least one first drive device, in the form of an electric motor and a spindle driven by the electric motor, to be arranged therein. Power and/or data cables may also be arranged therein. A control device comprising a circuit board may also be arranged in the at least one connection and/or functional element. It is also possible for a sensor device to be arranged in said element, the sensors monitoring, via the sensor field thereof, the environment outside the connection and/or functional element. In this context, an LED device may also be arranged so as to make lighting possible. Small monitors and/or loudspeaker devices may also be arranged in the connection and/or functional element. It is also possible for the connection and/or functional element to be pierced by drainage openings, so as to pass water into a carrier profile extending below the at least one connection and/or functional element. It is noted that these functions may also be provided in the first and/or second floor rail.
Particularly preferably, the door system, and therein the floor-side guide rail arrangement, further comprises at least one second floor rail arrangement, which extends parallel to the first floor rail arrangement. The second floor rail arrangement is constructed like the first floor rail arrangement, and comprises at least one second guide groove, which likewise extends in the longitudinal direction. The at least one first door leaf arrangement comprises a second door leaf, which comprises an engagement element that dips into the second guide groove in the longitudinal direction and is guided by said groove. The second floor rail arrangement likewise comprises a first floor rail and at least one connection and/or functional element, which in turn is arranged and/or fixed on the end face of the at least one first floor rail and lengthens it along the longitudinal axis, in other words in the longitudinal direction. The at least one first door leaf arrangement is thus formed as a telescopic sliding door, the at least one first door leaf and the at least one second door leaf being formed as sliding door leaves, which extend mutually parallel in different guide grooves and along stages of different length. As a result of the use according to the invention of a plurality of floor rail arrangements, different door types can be implemented. Thus, the individual floor rails of the different floor rail arrangements may be of different length, and thus be assembled from available pieces of the available floor rails. Different floor rails of a floor rail arrangement may also merely serve to fix door structures, for example.
In a further embodiment according to the invention of the door system, the floor-side guide rail arrangement further comprises at least one carrier profile, which likewise extends in the longitudinal direction and is arrangeable or arranged in a recess in the floor. The at least one carrier profile comprises a base wall and side walls, which delimit a shared receiving space, said space being accessible from an upper face (which faces a lower face of the door leaf) of the at least one carrier profile. The carrier profile comprises at least two support regions, which are spaced apart from one another, each support region being arranged between the upper face and the base wall and extending at least along a particular length in the longitudinal direction. The at least one first floor rail arrangement is positioned in each case on an upper support face of the support regions facing towards the at least one first door leaf. As a result, a very stable guide rail arrangement can be provided. Thus, the carrier profile can be rigidly anchored in the recess in the floor, and the individually assembled first floor rail arrangement can be laid on the corresponding support regions. So as still to be able to achieve thermal decoupling when required, a thermal insulation element, which in particular consists of a dielectric medium, is preferably arranged between the one first floor rail arrangement and the upper support faces of the first support region and of the second support region.
The at least one carrier profile may preferably also serve for drainage. In this case, the carrier profile is preferably formed watertight and/or arranged above a sealing film that encloses the base wall and the side walls. The carrier profile is sealed (in a moisture-proof manner) at the end walls, at least one end wall comprising, in the region of the base wall, an opening preferably having at least one tubular projection that serves to connect to a drainage pipe or drainage hose. As a result, masses of water that penetrate into the carrier profile through drainage openings in the first floor rail arrangement can be discharged.
Various embodiments of the invention are described in the following with reference to the drawings. Like subject matters have like reference numerals. In detail, in the corresponding drawings:
This movement is performed by at least one first drive device, which is operatively connected to the at least one first door leaf 2a of the at least one first door leaf arrangement 2. As a result, the at least one first door leaf 2a is displaceable along the first sub-stage 5. The same also applies to the first door leaf 3a of the second door leaf arrangement 3. The at least one first drive device or a further drive device is operatively connected to this door leaf 3a in such a way that the at least one first door leaf 3a of the at least second door leaf arrangement 3 is displaceable in the longitudinal direction 6 of the door system 1 along the second sub-stage 7. The first and second door leaf arrangement 2, 3 are fixed or guided displaceably in a ceiling-side guide rail arrangement 8 and a floor-side guide rail arrangement 9. The floor-side guide rail arrangement 9 extends in the longitudinal direction 6, as does the ceiling-side guide rail arrangement 8. The floor-side guide rail arrangement 9 comprises at least one first floor rail arrangement 10. The at least one first door leaf 2a of the at least one first door leaf arrangement 2 comprises an engagement element 11 (see
The at least one first floor rail arrangement 10 (see
The first floor rail 10a in
In principle, it would also be possible for the at least one engagement element 11 to be assisted in the guidance by additional rollers.
In
Moreover, there may also be arbitrarily many further floor rails (third, fourth, fifth, sixth, etc.), which are arranged mutually parallel. In this case, the construction corresponds to the previous ones.
Both the first and the second floor rails 10a, 10b comprise a first end face 14. These first end faces 14 have an engagement opening 23, through which the cavity 19 is accessible from outside the floor rails 10a, 10b.
The at least one connection and/or functional element 13 also comprises at least one upper wall segment 21 and two lateral wall segments 22a, 22b, which connect to the upper wall segment 21. The at least one connection and/or functional element 13 is arranged between two first end faces 14, facing towards one another, of the two floor rails 10a, 10b.
The at least one connection and/or functional element 13 comprises, on each of the first and the second end face 24, 25 thereof (
The fixing projection 26 could also further comprise additional latching means, making it more difficult to remove the connection and/or functional element 13 from the associated first or second floor rail 10a, 10b. A locking means of this type could for example be in the form of a ball latch.
In principle, it would also be possible for a further sealing means to be arranged between the at least one connection and/or functional element 13 and the associated first and second floor rail 10a, 10b. A sealing device of this type preferably consists of a plastics material and is also preferably formed on the connection and/or functional element 13 as a sealing lip, in particular injected onto the fixing projection 26 or close to the fixing projection 26. Preferably, the connection and/or functional element 13 consists of or comprises plastics material, in which case the sealing device is also preferably injected onto the connection and/or functional element 13 by 2K injection.
In this context, the at least one connection and/or functional element 13 is arranged in the first floor rail arrangement 10 in such a way that, in a closed position of the at least one first door leaf 2a of the at least one first door leaf arrangement 2, a secondary closing edge of the at least one first door leaf 2a is positioned over the at least one connection and/or functional element 13. As a result, particularly good thermal decoupling of the floor-side guide rail arrangement 9 is achieved. In particular, the at least one connection and/or functional element 13 has a lower thermal conductivity than the associated first and second floor rail 10a, 10b.
As a result, the first floor rail arrangement 10 has a non-constant heat transfer resistance in the longitudinal direction.
In principle, the at least one connection and/or functional element could also consist of metal or comprise metal.
The first floor rail 10a and/or the second floor rail 10b of the first floor rail arrangement 10 preferably consist of metal, and are also preferably produced as extrusions. In principle, it would also be possible for them to be formed of plastics material or to comprise plastics material.
It would also be possible for the first floor rail 10a to be open in cross section towards the floor, in other words away from a lower face 12 of the first door leaf 2a, the walls of the guide groove 15 extending approximately parallel to the lateral wall segments 17a, 17b of the first floor rail 10a. The same could likewise apply to the second floor rail 10b. If the second floor rail 10b is free of a guide groove 15, the second floor rail 10b would in this case be configured U-shaped in cross section.
By contrast, in
It is not shown that the upper wall segment 16 of the first floor rail 10a and/or second floor rail 10b of the first floor rail arrangement 10 is platinum-plated, along the entire length of the associated floor rail 10a, 10b or along a sub-length of the associated floor rail 10a, 10b, at least with a metal sheet that is adapted to the progression of the upper wall segment 16 including an optional guide groove 15. A metal plate of this type could be screwed and/or glued to the associated floor rail 10a, 10b. The metal sheet may be continuous and extend along the entire first floor rail arrangement 10 or be formed from a plurality of pieces that are positioned in succession in the longitudinal direction 6 of the first floor rail arrangement 10. The metal sheet is for example chrome-plated steel sheet.
In principle, it would also be possible for the upper wall segment 21 of the at least one connection and/or functional element 13 of the first floor rail arrangement 10 also to be platinum-plated with a metal sheet of this type, which is likewise adapted to the progression of the upper face 21.
The at least one first floor rail 10a and the at least one second floor rail 10b of the first floor rail arrangement 10 are of different length in the embodiment. They could also be of the same length. Preferably, however, the at least one first floor rail 10a and the at least one second floor rail 10b of the first floor rail arrangement 10 are longer than the at least one connection and/or functional element 13.
The connection and/or functional element 13 moreover comprises further special functions. These special functions are preferably integrated into the connection and/or functional element 13 directly during the production thereof. This facilitates the overall assembly of the door system 1. The floor rails 10a, 10b would merely need to be cut to the appropriate length, a fully pre-assembled connection and/or functional element 13, of which the special functions or functional arrangements have already been tested in advance, already being inserted.
Preferably, the connection and/or functional element 13 has at the upper wall segment 21 thereof a brush groove 33, which is preferably formed T-shaped or L-shaped in cross section (see
The locking bolt 38 may also dip through the guide blade 11 of the at least one first door leaf 2a. In this case, the locking receiving opening 37 is arranged in a wall segment that has come about as a result of the at least one first guide groove 15 in the at least one connection and/or functional element 13. The locking receiving opening 37 is formed to displace a locking bolt 38 from said opening into the at least one first guide groove 15, it being possible for the locking bolt 38 for example to be part of a locking cylinder. The at least one guide blade 11 of the at least one first door leaf 2a comprises an opening. In the closed position of the at least one first door leaf 2a, this opening is arranged opposite the opening of the connection and/or functional element 13. As a result, the locking bolt 38 can be inserted into the opening of the at least one guide blade 11 of the at least one first door leaf, causing said leaf to be locked.
To achieve additional security against unauthorised sliding-open or breaking-open of the at least one first door leaf 2a, the at least one connection and/or functional element 13 comprises at least one hook lock 39 and one release device 40, which is preferably part of the hook lock 39. The hook lock 39 is mounted displaceably, in particular rotatably about an axis of rotation 41, within the cavity 19 of the at least one connection and/or functional element 13. The hook lock 39 can be moved and/or pivoted and/or flapped and/or snapped from a release position, shown in
The release device 40 is formed to transfer the hook lock 39 from the release position into the blocking position and back.
In the embodiment shown, the release device 40 is arranged below the locking receiving opening 37 in the at least one connection and/or functional element 13. In this case, the release device 40 comprises a release arm 40a, the release arm 40a and the engagement arm 39a further preferably consisting of one integral part, in other words of a shared component, which is pivotable about the axis of rotation 41. This means that the hook lock 39 is preferably constructed in a single piece. The release arm 40a comprises, on the open end thereof, a corresponding contact region, which the locking bolt 38 contacts in the state where it engages in the locking receiving opening. As a result, the release device 40 is activated, causing the release device 40 to bring about the displacement of the hook lock 39, in other words the rotation of the hook lock 39 about the axis of rotation 41, from the release position into the blocking position. As a result of the rotational movement (
Preferably, the at least one connection and/or functional element 13 further comprises an energy store device 42, in particular in the form of a spring device. The energy store device 42 is formed to displace the hook lock 39 from the blocking position into the release position while contact of the release device 40 by the locking bolt 38 remains absent. Part of this energy store device 42 is therefore rigidly fixed or articulated on the at least one connection and/or functional element 13. The other part is fixed or articulated on the release arm 40a, as shown in
As a basic principle, the door system 1 has to be constituted in such a way that in the event of a power failure the locking bolt 38 does not engage in the locking receiving opening 37. In this case, the energy store device 42 ensures that the engagement arm 39a is disengaged from the at least one first door leaf 2a of the first door leaf arrangement 2. The at least one first door leaf 2a can therefore be slid open in the event of a power failure.
Further, a displacement device 141 is shown, which is formed to move the movable sealing device 140 from a first position (
In the closed position of the at least one first door leaf 2a, the movable sealing device 140 is preferably arranged exclusively below the lower face 12 of the at least one first door leaf 2a. Preferably, during an (opening) movement of the at least one first door leaf 2a or during an open position of the at least one first door leaf 2a, the movable sealing device 140 is arranged in a receiving groove in the upper wall segment 16 of the first and/or second floor rail 10a, 10b and/or in a receiving groove in the upper wall segment 21 of the at least one connection and/or functional element 13.
The displacement device 141 may comprise an electric motor, which is formed to move the sealing device 140 towards the lower face 12 of the at least one first door leaf 2a. This preferably only takes place in the closed position. This also includes in particular a short displacement distance before the closed position is reached (see above, <30%).
Alternatively, the displacement device 141 comprises a lever device 141, which consists of at least two lever arms 142, 143, the first ends 142a, 143a of which are at least indirectly interconnected, the lever device 141 being mounted pivotably. An indirect connection should be understood to mean that it may also be arranged at different points on a central body, for example on a shaft. However, the movement of one lever arm 142 always leads to a movement of the other lever arm 143. The two lever arms 142, 143 may be arranged in the same plane or in different but preferably parallel planes.
A second end 142b of the first lever arm 142 is connected to the sealing device 140 or arranged thereon. A second end 143b of the second lever arm 143 is arranged in such a way that, in the closed position of the at least one first door leaf 2a, said end either comes into mechanical contact with the at least one first door leaf 2a or comes into mechanical contact with a locking bolt 38. As a result, the lever device 141 is caused to pivot and/or to snap around, causing the movable sealing device 140 to be movable from the first position into the second position (evenly or jerkily). The second lever arm 143 may also for example be arranged in the at least one first guide groove 15. In this case, said arm comes into contact with the engagement element 11, in particular in the form of the guide blade of the at least one first door leaf 2a.
The displacement device 141 is preferably formed in such a way that, in the absence of mechanical contact on the second end 143b of the second lever arm 143, the lever device 141 pivots (back) and/or snaps back or snaps around, causing the movable sealing device 140 to be movable from the second position into the first position. This preferably takes place by way of a spring device 144 or merely under gravity.
The levelling device 45 or a further levelling device may also be arranged in the first and/or second floor rail 10a, 10b of the at least one first floor rail arrangement 10.
There may also be two levelling devices 45 provided in the at least one first floor rail arrangement 10. In this case, a distance of the door structure from the at least one first floor rail arrangement 10 can be changed. A height adjustment of the door structure is thus additionally possible.
To push the bolt 46 out of the opening, the actuation device is required, which comprises a rocker 48 having two lever arms 48a, 48b. The rocker 48 is preferably arranged completely within the connection and/or functional element 13. In this case, the bolt 46 is positioned on the first lever arm 48a. A screw 49 or engagement element 49 can be screwed into the connection and/or functional element 13 from outside the connection and/or functional element 13 via a second opening 50 in the upper wall segment 21. In this context, one end of the screw 49 or engagement element 49 can be brought into contact with the second lever arm 48b of the rocker 48. In this context, the second opening 50 is not overlapped by the door structure. The rocker 48 along with the two lever arms 48a, 48b thereof is mounted tiltable or inclinable about the rocker axis thereof in the connection and/or functional element 13. In the embodiment shown, the rocker 48 further comprises a mounting segment 51, which is hemispherical in cross section and can be mounted between two carriers 52a, 52b and accordingly rotated. The further the screw 49 or engagement element 49 is introduced, in particular screwed, into the second opening 50, the further the second lever arm 48b of the rocker 48 is pushed towards the floor, in particular towards the lower wall segment 27. Consequently, the first lever arm 48a is pushed closer towards the first opening 47. As a result, the bolt 46 is pushed further out of the opening 47. In this context, the first screw 49 can be screwed in particular into a thread in the second opening 50 of the upper wall segment 21, in such a way that the inherent weight of the door structure that lies on the bolt 46 does not lead to the screw 49 being able to be pushed out of the second opening 50 again.
In this case too, the connection and/or functional element 13 may already be equipped with the corresponding levelling device 45 during production.
The levelling device 45 or a further levelling device may also be arranged in the first and/or second floor rail 10a, 10b of the at least one first floor rail arrangement 10.
The at least one connection and/or functional element 13 may also comprise further additional functions. Thus, a heating element, in particular in the form of a heating wire, may be arranged therein. It is moreover possible for the at least one first drive device in the form of an electric motor to be arranged in the at least one connection and/or functional element 13. The same may also additionally or alternatively apply to a spindle that displaces the at least one first door leaf 2a along the longitudinal direction 6. Power and/or data cables may also be arranged within the at least one connection and/or functional element 13. For this purpose, corresponding plug-in connections may also be provided. A control device, which comprises for example a circuit board and/or a corresponding housing, may also be arranged within the at least one connection and/or functional element 13. The same may also apply to a sensor device that monitors the region around the at least one first door leaf 2a. This may include radar sensors, IR sensors, light barriers and/or ultrasound sensors. In this context, the sensor device may monitor the primary closing edge and/or the secondary closing edge. An LED device may also be provided. This may also include a screen device. The same also applies to a loudspeaker device.
Preferably, the upper wall segment 21 of the at least one connection and/or functional element 13 is closed. It would also be possible for drainage openings 55 (
The features set out here may also be introduced to the first floor rail 10a and/or to the at least one second floor rail 10b. This also applies in particular to the drainage openings 55. Thus, it would be possible for the first or second floor rail 10a, 10b to be open towards the floor, in other words towards the carrier profile 60, the drainage openings 55 being introduced at the corresponding upper wall segments 16.
The at least one carrier profile 60 comprises a base wall 61 and side walls 62a, 62b, which extend away from the base wall 61 and together enclose a receiving space 63. The receiving space 63 is accessible via an upper face 64 of the at least one carrier profile 60. The upper face 64 is arranged closer than the base wall 61 of the carrier profile 60 to a lower face 12 of the at least one first door leaf 2a.
The carrier profile 60 preferably consists of an extrusion and is also preferably formed from metal, in particular aluminium.
The carrier profile 60 comprises at least two support regions 65a, 65b, which are spaced apart from one another, each support region 65a, 65b being arranged between the upper face 64 and the base wall 61 and spaced apart from these two elements. The support regions 65a, 65b extend at least along a particular length in the longitudinal direction 6. Preferably, these two support regions 65a, 65b extend a distance in the longitudinal direction 6 equal to the length of the carrier profile 60, since as a result manufacture by extrusion moulding is possible. Nevertheless, interruptions may also be present.
In this context, the at least one first floor rail arrangement 10 is in each case positioned on an upper support face 66, facing towards the at least one first door leaf 2a, of the support regions 65a, 65b.
In principle, the base wall 61 could also serve as a support region. In this case, the at least one first floor rail arrangement 10 is positioned directly on the base wall 61.
This means that the carrier profile 60 extends a distance in the longitudinal direction 6 equal to the length of the at least one first floor rail arrangement 10. As explained previously, the first floor rail arrangement 10 preferably comprises the two floor rails 10a, 10b and the connection and/or functional element 13. The first floor rail arrangement 10 may thus be preassembled, in which case it is supported as a whole on the corresponding support faces 66 of the support regions 65a, 65b.
This state of affairs is shown in
Instead of the dielectric insulating elements 67a, 67b, a dielectric insulating plate could also be used. This would then be positioned jointly on both support regions 65a, 65b. It could further have openings for drainage.
So as to be able to fix the associated dielectric insulating element 67a, 67b securely, the first support region 65a comprises an engagement groove 68 (see
To ensure that the first floor rail arrangement 10, comprising the at least one first and/or the at least one second floor rail 10a, 10b and the at least one connection and/or functional element 13, cannot be lifted from the carrier profile 60, the at least one connection and/or functional element 13 preferably further comprises corresponding fixing means. These are in particular a continuous arresting opening 70 (see
The side walls 62a, 62b of the at least one carrier profile 60 end in particular flush with the at least one first floor rail arrangement 10 at the upper face 64. The wording “approximately” should be understood to mean that a height difference between the upper region of the carrier profile 60 and the corresponding upper wall segment 16 or 21 of the first or second floor rail 10a, 10b and/or the at least one connection and/or functional element 13 is less than 7 mm, 6 mm, 5 mm, 4 mm, 3 mm or 2 mm.
a and 13b show that the end faces of the at least one carrier profile 60 are closed by end walls 75, 76. At least one end wall 75 comprises, in the region of the base wall 61 of the carrier profile 60, an opening 77 comprising a tubular projection 78. The tubular projection 78 serves to connect to a drainage pipe or drainage hose. The other end face 76 is preferably free of openings. Rainwater that flows through the at least one first floor rail arrangement 10 through the already shown drainage openings 55 is collected by the base wall 61 of the carrier profile 60 and discharged through the opening 77. The opening 77 comprising the tubular projection 78 may also be introduced in the base wall 61 or in at least one side wall 62a, 62b of the carrier profile 60.
As explained previously, the carrier profile 60 is fixed in a recess in the floor. In this context, a distance of the carrier profile 60 from the floor is variable. This variable distance is set using bracing brackets 80, such as are shown by way of example in
In particular, a plurality of bracing brackets 80 mutually offset in the longitudinal direction 6 are used, which are arranged on both side walls 62a, 62b of the carrier profile 60 and engage in the holding notches 81 arranged there. In this context, each bracing bracket 80 can engage in different holding notches 81, in other words be spaced a different distance apart from an upper face 64 of the carrier profile 60. As a result, it is possible for the carrier profile 60 to be orientated horizontally even in the event of uneven floor conditions.
Preferably, however, the distance of the carrier profile 60 from a floor structure is altered in that the bracing brackets 80 have a slot, a screw connection engaging in the associated fixing opening in the carrier profile 60 through the slot. As a result, the associated bracing bracket 80 is fixed on the carrier profile 60. A distance between the at least one carrier profile 60 and the floor structure is adjustable depending on the position at which the screw connection passes through the slot of the associated bracing bracket 80. In this context, the slot is introduced in the part of the bracing bracket 80 that preferably extends parallel to the side walls 62a, 62b of the carrier profile 60. The slot may further additionally be open from one side. The fixing openings may fully pass through the associated side wall 62a, 62b or end therein. They in particular comprise an internal thread.
Referring to
The carrier profile 60, which is shown for example in
Referring to
A transition between the upper wall segment 16, 21 and the lateral wall segments 17a, 17b and 22a, 22b is preferably bevelled. This bevel serves to guide sealing elements 100, in particular in the form of a strip brush, such as are shown for example in
Moreover,
By contrast,
The first floor rail arrangement 10 and the second floor rail arrangement 110 can be introduced directly into a receiving opening in the base of the door structure. However, it is also possible for them to be laid in the carrier profile 60 and connected thereto. A further carrier profile 60 of this type can be seen in particular in
Preferably, the separating web 130 widens towards the open end thereof. The separating web 130 also extends in the longitudinal direction 6, and subdivides the receiving space 63 into a first and a second receiving chamber 63a, 63b. The at least one separating web 130 comprises further support regions 130a, 130b, which extend in the longitudinal direction 6. One of these further support regions 130a is formed as a support shoulder, and protrudes out from the separating web 130 into the first receiving chamber 63a, whereas another support region 130b is formed as a support shoulder and protrudes from the separating web 130 into the second receiving chamber 63b.
The first floor rail arrangement 10 and the second floor rail arrangement 110 are positioned on these support regions 130a, 130b and 65a, 65b.
In the first receiving chamber 63a, the support region may also be formed by the base wall 61. The same may also apply to the support region in the second receiving chamber 63b. In this case, the floor rail arrangements 10, 110 would be positioned directly on the associated support regions of the base wall 61.
Preferably, there is at least one further dielectric insulating element 131, which is formed bracket-shaped and is positioned on the further support regions 130a, 130b of the at least one separating web 130 and encloses an upper face of the at least one separating web 130. This further dielectric insulating element 131 may extend along the longitudinal direction 6 over the entire length over which the further support regions 130a, 130b also extend. However, it may also merely extend over a sub-length.
The further support regions 130a, 130b also in turn comprise engagement grooves, in which the further dielectric insulating element 131 engages.
Preferably, the further dielectric insulating element 131 is constructed divided in two and comprises two mutually separated dielectric insulating elements 131a and 131b, which are formed hook-shaped or Z-shaped and are preferably constructed identically, in terms of the cross section thereof, to the already known dielectric insulating elements 67a, 67b, in such a way that merely one type of dielectric insulating element 67a, 67b, 131a, 131b has to be produced. Because the dielectric insulating elements 67a, 67b, 131a, 131b preferably consist of plastics material, it is sufficient if merely one injection mould is manufactured. An extrusion moulding method would also be suitable for manufacturing them.
The fixing of the associated connection and/or functional elements 13, 113 preferably takes place, as stated previously, on the carrier profile 60. As explained previously, drainage is also possible.
Further separating webs 130 could also be provided, in such a way that further floor rail arrangements can also be received.
The at least one connection and/or functional element 13 of the at least one first floor rail arrangement 10 has a worse, in other words lesser or lower thermal conductivity than the at least one first floor rail 10a and the at least one second floor rail 10b of the at least one first floor rail arrangement 10. The same also applies to the connection and/or functional element 113 of the second floor rail arrangement 110 in relation to the first and second floor rails 110a, 110b therein.
The embodiments set out here, which have been explained in particular for the first door leaf 2a of the first door leaf arrangement 2, also apply to the second and further door leaves 3a of the first door leaf arrangement 2 and second door leaf arrangement 3.
The statements made for the first floor rail arrangement 10 also apply as a whole to the second floor rail arrangement 110 and to arbitrarily many further floor rail arrangements.
The connection and/or functional element 13, 113 may also be referred to as a connection and/or functional rail 13, 113.
