Abstract

The reliable sliding door construction has stationary regions (1) and sliding doors (2, 3). Both the stationary regions and the sliding doors have a height of 1-2 m above a floor level (22) of a passenger region (20) above which no means for separation of passenger region and track region (21) are arranged. The sliding doors are self-supporting and guided to move in or on the stationary regions with provision of an upper and lower guide (10, 11). One guide is provided as a roller guide (10) or ball bearing linear guide and one guide is a slide guide (11) or roller guide. An independent claim is included for a method for assembly.

Description

TECHNICAL AREA

The present invention relates to the field of sliding doors for platforms, that is to say the area of the doors with which the passenger area of platforms is separated from the track area. Furthermore, it relates to a method for mounting such a sliding door.

STATE OF THE ART

It is already known, for safety reasons between the person area, that is, the actual platform respectively platform, and the track area devices to install, which, as long as no train is retracted and is at a standstill, prevent passengers from entering the track area. This is especially important at subway stations, where typically the space is extremely scarce.

There are different constructions in this context, whereby a distinction is made between so-called platform screen doors and platform gate doors.

In the case of the closed-platform doors, closed-off station constructions, which are also closed at the top, are completed guaranteed between the platform and the track area over the entire height. In other words, the space available to the train is completely separated by a wall from the space of the passengers, and sliding doors are normally provided in the partition which automatically open only when the train is in the right position at a standstill.

In the platform doors, not the entire height between these two areas is separated, but it is provided only half a man-height partition, which has stationary areas or fixed parts, as well as disposed therebetween sliding doors. On the one hand, this construction may be indicated if it is not a closed railway station and thus there is no upper connecting edge for a railway terminating door, but on the other hand it may also be compulsory for other technical reasons. This, for example, if existing station structures must be retrofitted, in which the pressure compensation when entering the train is only possible via a corresponding ventilation through the passenger area. In addition, it may be imperative for fire police reasons that an unimpeded exchange of air between the track area and the platform area is possible, which is almost guaranteed only in the case of a platform door.

The construction of platform doors differs in technical respects from normal sliding doors in that on the one hand by the applied pressures when retracting the train from the side of the train and on the other hand, from the other, the platform side, by the possible loads by persons (in particular Stosszeiten) such doors are exposed to enormous loads. In addition, the doors can not be provided with a guide arranged above the door, and it is also desirable not to provide any guide rails or guide grooves in the floor, such that, as a rule, they can quickly become dirty and give rise to interruptions in operation. There are thus free-guided constructions required, which can be exposed to much higher loads, as is the case with conventional doors known from other fields. On top of that, in terms of reliability Requirements must be made, which far exceed those of other applications. On the one hand, the doors have to withstand reliable opening cycles in the range of millions, they must be easy to maintain, and especially in the retrofit, a construction must be provided, which on the one hand very flexible to different conditions (platform construction, distances of the doors of the tracks, height, etc.) can be adjusted, and which also can be mounted very quickly, since very often the assembly of such constructions without interruption of the transport services, that is, for example, at night, must be made.

These enormous technical requirements are contrary to the fact that for aesthetic and space reasons as slim as possible constructions are desired using transparent areas.

From completely different technical fields different sliding door constructions are known. In the DE 102 31 841 A1 discloses a sliding door consisting of two glass sheets interconnected by means of a spacer, wherein rollers for guiding the sliding door within the groove are arranged on the lower edge of the door. The DE 34 01 105 A1 describes a sliding gate or a base bar for such. In the GB-A-2 075 564 which document has all the features of the preamble of claim 1, a sliding door construction for fences is described, which has a fixed frame and a sliding door in a roller guide. These embodiments are normal sliding doors, not platform doors.

PRESENTATION OF THE INVENTION

The invention is therefore an object of the invention to propose an improved sliding door construction for platforms, especially as a platform door. Specifically, it is a matter of proposing a construction with which a passenger area of platforms can be separated from a track area in the closed state, as long as the approach to a retracted train is to be prevented, and which in the open state with retracted train allows access, comprising stationary areas and sliding doors, where both the stationary areas and the sliding doors have a height in the range of 1-2 m have above the floor of the passenger area and above no means for separation between the passenger area and track area are arranged.

This object is achieved by a sliding door construction with the features of claim 1. In this construction, the sliding doors are designed to carry freely and movably guided in or on the stationary areas. For this purpose, an upper and a lower guide are present, wherein a guide is designed as a roller guide or as a ball linear guide, and a guide is designed as a sliding guide or as a roller guide.

It is therefore a double guide in a self-supporting sliding door, which ensures increased stability and high reliability.

The essence of the invention is that the upper guide is disposed substantially halfway up the sliding door, the portion of the sliding door disposed above the upper guide being formed of glass or other substantially transparent material having a substantially exposed upper edge. The region of the sliding door arranged above the upper guide is preferably made of glass.

This completely or partially transparent plate with a substantially exposed upper edge results in an elegant construction, which exerts on the passengers a much smaller restrictive effect than constructions in which a frame area is provided at the upper edge.

According to a preferred embodiment, the lower guide is designed as a roller guide or as a ball linear guide, and the upper guide as a sliding guide.

Preferably, the lower guide is arranged substantially in the lower region of the sliding door, wherein the upper guide according to the invention is arranged substantially at half the height of the sliding door. Thus, it is possible to arrange between transparent areas, so that on the one hand through the doors no restrictive effect, and so that the passengers on the platform can observe the incoming train respectively that the passengers on the train retracting can watch.

A further preferred embodiment is characterized in that the drive of the sliding doors is arranged on the guide designed as a roller guide or as a ball linear guide, preferably arranged below, and the transmission of the drive force takes place with the aid of a toothed belt between drive arranged in the stationary area and the sliding door. In terms of compact design and reliability, the use of a toothed belt in the lower area proves to be particularly advantageous. The toothed belt can be designed, for example, circumferentially and be connected via a driver with the sliding door respectively particularly preferably with a provided on the sliding guide rail, or it is possible to connect the timing belt at its ends with a guide rail provided on the sliding door.

A particularly preferred embodiment is characterized in that for each sliding door a drive is mounted on a bottom plate of the respective stationary area, which is preferably an electromotive drive e.g. with worm gear, and that the drive drives a toothed belt drive pulley, which is arranged offset via toothed belt pulleys from the main direction of the toothed belt downwards or upwards. In particular, when the toothed belt is firmly connected at its ends with a guide rail provided on the sliding door, the tension of the toothed belt can thus be controlled and adjusted by means of the toothed belt drive roller and a particular reliability of construction results.

Another preferred embodiment is characterized in that a horizontal guide element is provided at the stationary area, in particular via at least two support columns attached to a base plate, which guide element has a length of at most the width of the stationary areas, so that this guide element does not have the stationary areas stands out. Furthermore, a guide rail is then arranged on each sliding door, which engages in or engages around the guide element, wherein rollers or balls are provided for the movable displaceability in the lateral direction.

To ensure that the guide rails do not collide with the doors open, and that doors can be arranged as close together as possible, it proves to be advantageous to offset the guide elements and the associated guide rails of two adjacent sliding doors in height at least so far that the Guide rails of open and provided adjacent juxtaposed door openings sliding doors come to rest without contact over each other. Preferably, the toothed belt is arranged substantially below the guide rails or the guide element. The plane of the toothed belt preferably runs horizontally.

According to another preferred embodiment, both guides are to provide on the platform side as elegant as possible construction available, which is also protected against access, arranged on the side facing away from the platform of the sliding door and the stationary areas.

In order to meet the wide displaceability of the sliding doors structurally simple, and not to make laterally projecting elements, it proves to be advantageous to form the slide designed as an upper guide as an at least three-part telescopic guide, which has a fixedly connected to the stationary area guide profile , has a fixedly connected to the respective sliding door guide rail and a relative to both other elements movable telescopic profile. Such a telescopic profile can also be configured based on a roller profile instead of a sliding profile. If a sliding guide is used, it additionally proves to be advantageous if appropriate to provide the sliding areas with a special coating, for example made of PTFE.

The upper guide was preferably on a rear side of the fixed part arranged and fixed to the fixed part guide profile, particularly preferably in the form of an H-profile, which engages in a slot designed as part of the sliding guide profile in the form of a slide rail. In other words, the slot of the profile is open to the platform area. It also proves to be advantageous according to close this slot with sealing lips to avoid trapping or contamination.

One of the problems with such constructions is the fact that electrical potential differences exist between the train and the platform area. Accordingly, comprehensive isolation of the platform area with respect to the rails normally used for grounding is enormously important. Accordingly, the sliding door structure should be as well insulated as possible with respect to the floor of the platform. This can be achieved according to the invention by a special embodiment of the base plate on which the stationary areas are arranged, or which forms part of the stationary area.

It must be pointed out that this special embodiment or the type of mounting of such a floor plate, independently of the above-mentioned sliding door construction, has inventive character and thus is also worthy of protection independently of this.

Such a construction is characterized in that the stationary areas are fastened in each case via at least one provided with an insulating layer covering the entire surface base plate at the bottom of the people area with the aid of anchor bolts or pins. The insulation of the entire surface of the bottom plate results in that, for example, arranged on the ground dirt or moisture can not cause an electrical contact between the bottom and the bottom plate and the stationary structure arranged thereon can take place.

This can be achieved particularly effectively if the insulating layer covering the entire base plate is made of a plastic material, particularly preferably of a thermoplastic polyamide, e.g. PA11, consists, and is formed with a thickness in the range of 0.2 -1.5 preferably 0.25 - 1 mm.

A first preferred embodiment of such a bottom plate is characterized in that the bottom plate has mounting holes, which have a substantially larger diameter than the anchor screws or pins (typically diameter of the holes 2-5 times larger than the diameter of the screws or pins, with which the plate is mounted on the ground), and that for thrust transmission and positive connection between the bottom plate and anchoring screws or pins an insulating filler material, in particular made of plastic or resin such as acrylic resin, is arranged. The resin is preferably mixed in such a way that on the one hand it has the required strength and on the other hand it is so brittle that it can be removed again if the entire structure has to be replaced.

First, this design ensures that tolerances between it is also possible to ensure that the screws or pins in electrical contact with the base do not come into electrical contact with the mass of the base plate. In order subsequently to obtain no contact during assembly, it proves to be advantageous to provide insulating elements between the base plate and the floor (also as spacers) and between the fastening means, with which subsequently the base plate is fastened with the screws or pins respectively. If pins are used, they are preferably threaded at their upper end, and nuts are threaded onto this thread to secure the bottom plate.

In connection with such a sliding door construction, it is advantageously possible for at least one of the stationary areas in the region of its upper edge, particularly preferably at least partially integrated into a cover delimiting the upper edge of the respective stationary area, to have means for indirect illumination of the area of the person.

This lighting possibility is independent of the above-mentioned specific design of the sliding door construction, as long as the sliding door construction has a height in the range of less than the total height of the passenger area. This illumination option is particularly advantageous when the stationary areas have a height in the range of 1.7-2 m above the floor of the person area. Then that is. Indirect lighting via an illumination of the ceiling area of the passenger area is optimally possible without the persons in the passenger area being dazzled.

This specific arrangement of light sources at the upper edge of the stationary areas is advantageous, inter alia, since means for electrical supply are already provided in the area of the sliding door construction, since the illumination means are arranged at a height which facilitates the maintenance of the illumination (for example cleaning or replacement of lamps , This is in the arrangement of lamps on the ceiling usually associated with a lot of effort) much easier, and because the indirect lighting creates a spacious sense of space, which especially at underground stations is essential.

The means for indirect illumination of the personal area can be known lamps which form a substantially upward or at most vertically oriented light cone. Possible are z. As mirrored light sources such as neon lights, but also LED light sources, headlights, especially halogen headlamps, etc., typically with a light intensity per light source of preferably more than 10'000 lumens, and the lamps can also have means for bundling or for targeted expansion of light feature. The light cone thus forms preferably with the vertical, for example, an angle in the range of 0-90 or better 0-45 °, since this ensures that passersby are not disturbed by the direct light. This beam of light provides indirect light from the ceiling for the area of the person as the illuminated ceiling throws the light back.

In order to further improve or specifically align the indirect radiation of the person's area, it is possible to arrange further means on the ceiling (or generally above the light source) for better indirect illumination of the area of the person. Of course, such means can also be arranged for targeted illumination of the track area. These further means are, for example, one or more reflectors (which may be differently oriented), particularly preferably in the form of mirrors, which are fastened to the ceiling, for example.

A particularly versatile construction is possible if the means for indirect illumination of the personal area are so fastened in the region of the upper edge of the stationary area that the light cone produced by them can be adapted to local needs, with particular preference setting the direction of the light cone in a direction perpendicular to the running direction of the platform by a rotation of the means formed as a lamp about an axis substantially parallel to the direction of travel of the platform is possible.
In connection with such a sliding door construction, it is still advantageously possible that in at least one of the stationary areas (or on one of the sliding doors) display means for the transmission of information to persons in the passenger area are arranged. These presentation means may convey the information indirectly (for example, projector projecting onto a projection surface on the ceiling or the wall or back onto an area of the stationary area), or they may provide the information directly. In other words, the display means may be at least one display means selected from the following list: LCD screen, LED display, projector, neon sign, illuminated sign, advertising poster (including roll poster), these means of representation preferably information in time-varying form for Make available.

It should be emphasized that these means of presentation can be directed both against the passenger area, as well as against the track area, so to speak, to the rear. If the presentation means are directed against the person area, the information is transmitted directly to the persons who are in the person area arranged in front of the sliding door construction. If the presentation means are directed against the track area, that is, to some extent towards the rear, the information presented there can either be picked up by people on the opposite platform (that is, for example, if no train is standing on the tracks and looking through the transparent areas of the sliding doors ), or even people who are in an arriving train and looking out through the windows of the train, which may be both passengers and staff. Furthermore, it is possible that the presentation means are provided in the stationary wall elements between the sliding doors and their stationary areas in which the suspensions for the sliding doors are arranged.

This possibility for transmitting information is independent of the above-mentioned specific design of the sliding door construction, as long as the sliding door construction has a height in the range of less than the total height of the passenger area.

In a particularly ideal manner, such a presentation means can be arranged in at least one of the stationary areas if the stationary area has at least one transparent area facing the person area, such as particularly preferably a glass area, and if the presentation means is arranged behind this transparent area with respect to the people area , For example, it is possible to place one (or more) LCD screens at least at eye level in the range of 100-200 cm above ground behind the glass surface of the stationary area.

This transmits the information at the correct height and at a point where passers-by are always watching while waiting for the train. Additionally or alternatively, it is possible to arrange a preferred variable advertising over at least half the height of the stationary area behind this transparent surface. It may also be about LCD advertising, but it is also possible to provide a fixed advertising or, for example, a rolling advertising or a differently designed time-varying advertising. For example, it is also possible to apply a partially transparent information carrier from behind onto the transparent surface and to illuminate it on the back.

In particular, when the stationary area has a peripheral frame, it is possible to arrange the display means on respectively in this frame on the side facing the sliding door or above. This proves particularly for warning messages or status messages (for example, arrows directed against or opposite to the sliding door, for example in the form of LED signals when the sliding door begins to close or to open). Such means are then preferably substantially over at least 1/2 of the height of the stationary area.

Typically, the presentation means transmits information selected from the following list: advertising, news, sporting events, timetables, current train and network train information, (interactive) internet information, camera recordings, alerts, entertainment, which information may also be used sequentially and / or in combination. or be provided in parallel and preferably in a time-varying form.

Furthermore, the present invention relates to a method for mounting (retrofit) of such sliding door designs. The method is particularly characterized in that holes are provided in the ground (for example in the correct pattern using a template), and then anchor bolts or pins are secured in these holes, these screws or pins enough up over the floor protrude far. The screws or pins can be screwed in or cast. Subsequently, insulating spacers (in the sense of washers, for example made of plastic or other insulating material) are placed on the anchor bolts or pins. Then a bottom plate is placed with holes provided accordingly over the protruding above the ground anchor screws or pins.

The base plate or base plate can also be sunk in the platform floor.

The holes have, as already mentioned above, a diameter which is substantially larger than the diameter of the screws or pins. Subsequently, the spaces between the holes and the anchor screws or pins with insulating filling material are poured out, and then the bottom plate after applying more insulating spacers (for example, washers as mentioned above) with the aid of nuts or the like. attached. Preferably, the structure of the stationary areas is already screwed on the bottom plate o.ä. (To this end, threaded holes, in the form of blind holes, in the upper surface of the bottom plate may be provided), whereby it is ensured that no contact with the ground can take place. Thus, after the anchor bolts are mounted in the platform, the entire structure (fixed part), which is already pre-assembled and tested in the factory (fixed part including sliding sash are completely assembled and put into operation in the factory), screwed.

Further preferred embodiments of the inventive sliding door construction and the inventive method for mounting a Such sliding door construction are described in the dependent claims.

WAYS FOR CARRYING OUT THE INVENTION

FIG. 1a) shows a perspective view of a not belonging to the invention sliding door construction.

In principle, such a sliding door construction comprises fixed parts 1, which are arranged on both sides of the actual door opening. The door opening is closed by two sliding doors 2 and 3, wherein alternatively only one sliding door can be arranged. The two sliding doors 2 and 3 close synchronously and in opposite directions. Such sliding door structures are arranged in succession at the platform edge. However, the sliding door structures do not follow each other directly, but between sliding door structures, such as one in FIG. 1a) is shown, further wall elements are arranged, which do not constitute a door opening. Such wall elements are typically also formed similarly transparent. These wall elements are required inter alia, since otherwise the doors 2, 3 would encounter each other during the opening process.

The fixed parts 1 comprise a bottom plate 6, on each of which the upper construction is attached. The upper construction essentially comprises in each case a frame 30, which is bounded in the head area by a cover 12. In the cover lamps 39 are arranged, which serve to emit optical signals during the opening process or respectively when closing the doors 2, 3, for example by lightning. As part of the superstructure of the fixed parts 1, for example, a transparent area 4 is arranged for aesthetic reasons. Furthermore, each of these superstructures comprises a storage for the doors 2, 3, which will be described in detail below, as well as a drive. At least one fixed part per sliding door construction also includes a controller, which u. a. is connected to an overall control of the entire system of sliding doors to a platform, so that a coordinated opening process or closing of all sliding doors at the right moment, that is, in the correct position of the train, can be ensured. The sliding doors 2, 3 are partially equipped with transparent areas 5.

In FIG. 1b ) such a sliding door construction is shown in a view from the side of the platform. It can be seen here that the fixed parts 1 each comprise a frame 30. Within this frame, a transparent area 4 is arranged in each case. This transparent area is in a sense designed as a door, which can be opened to make the underlying functional parts such as drive and suspension and control for maintenance or installation accessible. For this purpose, these transparent areas 4 are provided with a lock 24.

The sliding doors 2, 3 in turn likewise comprise a peripheral frame 26. Where the sliding doors adjoin one another, a sealing lip 28 is arranged on this frame. Preferably, such sealing lips 28 are configured such that the sealing lips 28 engage with one another by adjacent doors. Furthermore, transparent areas 5 are present in this frame 26. However, these transparent regions 5 do not extend all the way to the bottom, since in the lower region, due to the suspension arranged behind them, there is in each case one diaphragm region 25.

The sliding doors can not be opened from the side of the platform in principle by simple manipulations. In order to allow, if necessary, but a mechanical opening of the sliding doors 2, 3, emergency opening options 23 are provided, which can only be operated using appropriate keys of the staff. The two sliding doors 2, 3 are designed to be cantilevered, that is, between the bottom and the lower edge of the door remains a small gap, which is typically in the range of 5-30 mm.

A fixed part 1 has, for example, a total width a of approximately 600 mm maximum, and the door opening may have a width b of 2100 mm. It is generally possible to open doors b in the range of up to 2500, normally up to 2200 mm. Depending on needs, the width of the door openings can be adjusted, and this is possible without the construction of the fixed parts 1 must be changed. So a construction is possible, which can be installed without major adjustments to the local conditions. The sliding doors 2, 3 have a height c, so that the upper edge of the sliding doors 2, 3 is located approximately 1500 mm above the floor. Normally, such doors are constructed with heights in the range of 1000-2000 mm.

Figure 1c ) shows a view of such a sliding door construction from the side of the tracks. It can be seen here that behind the apertures 25 (cf. FIG. 1b ) the actual suspension of the sliding doors is hidden. This suspension is covered with a cover 9, so that the pollution of the suspension can be avoided and thus the passengers can not access.

Since it may be necessary under certain circumstances in emergency situations that passengers in the train open such sliding doors 2, 3 manually, handles 27 are provided on this side of the doors, with which the sliding doors 2, 3 can be opened. Typically, these handles 27 are designed to automatically open the doors when manipulated and still present, but also to allow door opening when force is applied, with no power left.
Figure 1d ) shows such a sliding door construction in the open state from the side of the platform, as well as immediately below an associated floor plan. It can be seen that due to the much smaller width of the fixed structure 1, the sliding doors 2, 3 protrude laterally beyond these fixed parts 1. Specifically, each sliding door has a total width d including suspension of about 1700 mm (depending on the clear width of the door), since it has a guide rail 18 due to the cantilevered design, which projects beyond the actual width of the door to the rear. Essential in this context is also that the overall construction depth is not too large, so that the required space is not too much platform surface consumed. The proposed construction is characterized by a very small construction depth, so in the above basic dimensions, the construction depth e is about 300 to 400 mm possible.
FIG. 2a ) shows a section through such a sliding door construction. It can be seen how two suspensions 10 and 11 are present, with both suspensions are arranged on the web side 21, and not on the platform side 20. The upper suspension 11 is disposed substantially in the region of the upper edge of the sliding doors 2, 3, and is described in detail below.

The lower suspension 10 is arranged in the lowest area of the sliding doors 2, 3. The sliding doors 2, 3 have a cover 9, behind which the suspension 10 is hidden. The suspension 10 comprises a stationary part in the form of a guide element 19, which is arranged on the fixed part 1. A guide rail 18 is fastened to the respective sliding door and together with the guide element 19 forms a roller bearing or a ball bearing (for example a ball cage) via which the respective sliding door can be laterally displaced.

The height f of the diaphragm area 25 or the cover 9 above the ground is approximately 400 mm, and the base plate 6 is spaced at a distance g of approximately 5 mm from the floor. The bottom plate 6 has a depth k of about 360 mm and is typically set back for safety reasons of the platform edge 46 by a distance 1 of about 75 mm. This value is project-specific and depends on the light profile of the train. The bottom plate is anchored with two rows of anchoring elements 7 in the ground, the first row of Anchoring elements is offset by h in the range of 110 mm from the rear edge of the bottom plate 6, and the two rows of screws are spaced by about i = 210 mm.

The drive area is in the following FIGS. 2b) -e) shown in detail. In FIG. 2 b) is a sectional view indicated. From this it can be seen that attached to the bottom plate 6 support columns 34, a horizontal guide member 19 is fixed to the fixed part. This guide element 19 has a width, which in any case is less than the total width of the fixed part 1. Also attached to the bottom plate via a mounting plate 37 is the actual drive, which is ensured by a horizontally disposed electric motor 36. The electric motor 36 has, for example, a worm gear, which drives a toothed belt drive roller 31. Furthermore, 31 Zahnriemenumlenkrollen 32 are arranged above this belt drive pulley, which in connection with the Figure 2d ) should be discussed. For attachment of the toothed belt 35 either a driver is provided with circulating toothed belt, or a fastening device 33 on the guide rail 18th

The Figures 2c ) and d) show two views of the drive area from the tension side and the platform side, respectively. It can be seen that on the angled mounting plate 37, which is fixed by means of mounting screws 38 on the bottom plate 6, below the toothed belt drive roller 31 and above symmetrically laterally offset two Zahnriemenumlenkrollen 32 are arranged.

In this embodiment not belonging to the invention, the toothed belt 35 is fixed at its ends to the guide rail 18, and is deflected from each side from above via the Zahnriemenumlenkrolle 32 down to the toothed belt drive roller 31. The tension of the toothed belt 35 can thus be adjusted either by a lateral displacement of the toothed belt deflection rollers 32 or by a horizontal adjustment of the toothed belt drive roller 31 (also possible in each case via a sprung mounting with counter tension). This specific arrangement of the individual elements, that is to say horizontal drive motor with worm gear, toothed belt drive roller 31 with deflection via two toothed belt deflection rollers 32, allows a particularly compact design, and the use of a belt to the drive proves to be particularly robust.

From the perspective view according to FIG. 2e ) shows that the support columns are preferably designed as a hollow profile, wherein the guide member 19 is attached thereto from the platform side. It is possible to arrange two individual guide elements 19 on the two support columns 34, or else, and this is in Figure 2 e) illustrated, it is possible this guide member 19 also form a rail, in which individual bearing elements are arranged distributed. The guide rail 18, which is fixed to the sliding doors 2, 3, is designed as a double U-profile, wherein the inner U-profile surrounds the guide member 19 for guiding and thus the inner U-profile serves as a tread, and wherein the outer U Profile is provided for the comprehensive protection of the leadership.

The upper guide 11 is off FIG. 2f ) better visible. At the upper edge of the sliding doors 2, 3, an upper door profile 16, which forms part of the frame 26, is arranged. At this upper door profile 16, a guide rail 13 is attached. Preferably, this guide rail has a width which corresponds approximately to the width of the sliding door 2, 3, but it can also protrude slightly behind the door, as in FIG. 1 d) is shown. As a fixed element in return in the upper part of the fixed part 1, a guide profile 15 is attached. However, it does not directly engage the guide rail 13 in the guide profile 15, but the upper guide is formed as a telescopic guide, in which a telescopic section 14 is movably arranged between these two elements. The telescopic profile 14 is thus both displaceable with respect to the guide rail 13 and with respect to the guide profile 15. The individual elements slide on each other, that is, the upper guide 11 is formed as a sliding guide. The use of the telescopic profile allows a particularly large width of the guide, without a chunky guide device is necessary.

An additional essential element of the present sliding door construction is the attachment to the floor. FIG. 3a ) shows in a detail the floor area of the construction. A bottom plate 6 is provided with fastening elements 7 in the platform material 40 anchored. All elements of the fixed part 1 are then attached to this base plate 6. First, therefore, a bottom plate 6 is fixed on the platform by drilling appropriate holes in the platform. In these holes, the fasteners are either screwed (anchor bolts), or poured in, for example (anchor pins) or the like. The base plate 6 is now placed over the ends of the fastening elements projecting above the floor level, the fastening elements 7 passing through holes 44, 45 provided correspondingly in the base plate 6. Insulating spacer elements 42 are also provided between the base plate 7 and the floor, wherein these, for example, as in FIG FIG. 3a ), in the form of insulating washers 42 may be formed. Similarly, 6 insulating washers 41 are now placed on top of the bottom plate and only then fixed the bottom plate with the aid of nuts 8 on the ground. The nuts 8 are screwed onto the upper end threaded fasteners 7.

The floor panels are covered over their entire surface with an insulating coating. It is a coating of thermoplastic polyamide, such as thermoplastic PA11, which is configured with a thickness of about 0.4 mm. It may be, in the coating material, for example, the product Rilsan ^® from Atofina (DE), such thermoplastic PA11 materials can, for example, in fluidized bed coating, by electrostatic spraying, powder spraying, etc. by Applying, wherein the workpiece may be subjected to a surface pretreatment beforehand, for example, cleaning and application of a primer or the like. In order to ensure the electrical insulation effect between the platform and sliding door construction, also the holes 44, 45 designed much larger than the diameter of the fasteners 7. After attachment of the fasteners 7 in the ground, the laying of the spacer elements 42 and the bottom plate 6, the gap between the fastening elements 7 and the edge of the bores 44, 45 with an electrically insulating filling material 43, for example acrylic resin, for example acrylic resin Beracryl ^® the company Troller AG, poured out. The material is preferably mixed in such a way that on the one hand a sufficient strength for holding and, on the other hand, a brittleness which allows removal upon disassembly. The insulating effect of this filling material ensures that there is certainly no electrical contact with the ground in the region of the fastening elements. As in FIG. 3b ) is thereby designed so that a sufficient tolerance circle p of 10 to 20 mm is formed.

In detail, such a floor slab is in Figure 3c ). It can be seen how in the area facing the platform, the fastening by three screws via three holes 45 rather in the central area, as in the lateral area, the two columns 30 of the fixed part 1 are arranged. The three tracks 44 facing the track area are widely distributed. The holes have a diameter q of 30 mm, while the anchor bolts or anchor pins 7 have a diameter r in the range of 12 mm. The first row of holes 44 is offset by w in the range of 110 mm to the rear, and the second row of holes 45 by 315 mm. The bottom plate 6 has a total width u of about 600 mm, the outer two holes 44 of the first row being offset from the center by t = 265 mm, while the lateral holes 45 of the second row are offset by s = 100 mm.

The installation of such a sliding door design is particularly simple, since first the bottom plate as described above is fixed to the ground and then the fixed parts 1, that is their superstructure, put on respectively can be screwed. The fixed parts 1 are standard elements, which are designed independently of the width of the sliding doors. Between the fixed parts wall elements are now provided in the closed areas, which only need to be adjusted in length, which can be done either on site or before. The sliding doors 2, 3 can then be suspended from the track side, and last but not least the toothed belt 35 has to be placed around the corresponding elements 31 and 32, respectively, and tensioned. The controller can be designed so that it is self-learning, which means that when first switching on a measurement and an adjustment of the opening process takes place automatically.

An important point about installation is the fact that the entire fix structure including the door can already be assembled and tested at the factory. On the platform, in fact, only the bolts need to be installed in the platform and then the entire fixed structure placed on top. The cables are laid in advance and immediately connected as soon as a fixed structure is installed. From this moment on, the doors can open and close automatically (this is especially necessary for the nightly retrofit procedure, because the trains leave the next morning). This also means that during the installation phase during the day already installed doors already work automatically.

The creation date of the load-bearing building fabric of platforms is sometimes very far back. The construction of the platforms has traditionally hardly been altered in the past and is therefore generally unsuitable for absorbing the additional stresses in the assembly of sliding door construction. Although the attachment with the aid of the bottom plate 6 may help partially here, but there are a variety of situations where the holding force of the floor construction can not be accepted.

A typical situation is in FIG. 3 d) shown. Normally, a platform is constructed on a substructure consisting of a rear wall portion 80 and a front wall 82. Between these two support members there is normally a non-load-bearing cavity 81, which for example can be filled with sand. On the rear wall portion 80 and the front wall 82 is a concrete plate 84, which forms the actual supporting structure. On this concrete plate 84 is usually a soft coating 85 (for example, asphalt) is provided. The usually soft pad 85 usually does not support or supporting function but charged the concrete slab 84 in addition.

On this surface 85, the bottom plate 6 is normally placed and connected to the concrete plate 84 with anchor bolts. The problem with this is that the projecting portion 86 of the concrete slab 84 is usually not able to absorb the forces applied to such a system. These forces are in FIG. 3e ) illustrated. It turns out that with a sliding door of a height of about 1.5 m following Moments or forces applied: M ₁ = +/- 4972 Nm; Q ₁ = +/- 4200 N; N ₁ = - 2241 N.

Regardless of the design of the sliding doors used, it turns out that such forces, with a typical thickness and reinforcement of the concrete slab 84, often can not be absorbed by this construction without further reinforcement measures being taken.

In any case, the obvious possibility for such reinforcement at the outset should be to support or reinforce area 86 from below. However, support from below is generally not possible without major interruptions in operation, and involves the risk that installations arranged below the area 86 (for example data lines, electrical lines, water pipes, etc.) must be damaged or misplaced during structural measures.

Accordingly, the present invention also relates to a, in principle, independent of the above-described specific construction of a sliding door reinforcement measure for such platform structures and the individual structural elements used for this purpose.

In this approach it is assumed that, if any, initially the topping 85 is removed, since this can not take any supporting function anyway, and represents at most a further burden on the underlying concrete slab 84.

Then, as in FIG. 3 f) is shown, preferably applied over the entire depth of the platform and at least in the areas in which the bottom plates 6 are arranged, (strip-shaped) elements on the concrete slab 84. These elements are capable of the forces occurring at the bottom plate 6 backwards, and in particular via an anchorage at the anchor plane 91 to the front wall 82 and at the anchor plane 92 to the rear wall 80 (for example via anchor bolts , which project through the concrete slab 84 into the underlying supporting structures 80/82), dissipate and thereby relieve the area 86. Particularly preferred are these elements to sheets, such as trapezoidal sheets 88, which are supplemented with fine concrete. Below this, cavities 90 can remain. Between the strip-shaped elements 88, a coating 89 can then be provided. It is also possible, in turn, to apply an upper covering on or under such a situation, for example to raise the general level of the platform. The mass in mm are in the FIGS. 3e ) -g) for a possible structure.

The reinforcing measure thus follows the idea to replace the previously existing topping, which is not static, against a sufficiently rigid and lightweight support structure. The said elements are thus preferably steel composite ribbed plates consisting in particular of a trapezoidal sheet with fine concrete supplement.

The height of the system or elements 88 is normally at least 60mm. The system is applied directly to the load-bearing reinforced concrete 86 of the platforms. This means that the currently existing covering of about 70-100mm thickness is removed before assembly. If a level adjustment of the top edge of the platform to the top edge of the train floor is to take place, the height can be set correspondingly greater.

The fixed structures (ie base plate and sliding door construction) are now connected to the element 88. The fixed structure loads are guided through the ribbed plates to the armature planes 91 and 92. Due to the selected dimensions, depending on the local situation, a sufficiently large area is available for anchoring the forces in the old stock.

The system is essentially applicable to every type of platform.

Particularly noteworthy is the fact that the existing cavities 90 of the ribbed plate system, the design weight is reduced compared to the current situation, if no level adjustment. The system is characterized by a high degree of prefabrication in the workshop. To prepare the measure only a partial blocking of the platform is required.

• Vorfertigen der Stahl-Rippenplatten;
• Ggf. Abtragen des Belages 85 bis auf den Beton zum Beispiel durch Fräsen o.ä.
• provisorischer Schutz der Eintiefungsbereiche;
• Liefern und Montieren der Verstärkungskonstruktion;
• Auffüllen und Vergiessen der Rippenplatten mit Feinbetonergänzung.

The mounting of the ribbed plates takes place, for example, in the following steps:

• Prefabricating the steel ribbed plates;
• Possibly. Removal of the coating 85 down to the concrete, for example by milling or the like.
• provisional protection of the recessed areas;
• Supplying and mounting the reinforcing structure;
• Filling and casting of the ribbed plates with fine concrete addition.

The fine concrete can be plastic-modified. For example, this results in a compressive strength of 60 MPa, a bending tensile strength of 14 MPa at a thickness of 10-20 mm.

The system does not require demolition of components at the platforms. Thus, it represents only a minimal invasive intervention in the historically grown and monument preservation worth preserving building fabric.

In FIG. 4 an embodiment of the invention is shown. In this case, the upper guide is not arranged at the upper edge of the construction, but approximately at half height or slightly above the sliding doors. For aesthetic considerations, it may prove advantageous to make the top of the sliding doors as transparent as possible in order to minimize the constricting effect of such constructions occurring especially in narrow platforms. In the construction according to FIG. 4 Accordingly, the upper guide is arranged halfway up, and above and below each glass plates 48 and 49 are arranged. The arranged in the lower region lower guide is designed the same as described above. To make the entire construction appear as uniform as possible, not only the sliding doors 2, 3 are each designed with a central guide 54, but also the wall elements 47, while doing this intermediate rail 53 can hold either an upper and a lower glass plate as in the sliding doors , It is also possible to arrange this intermediate rail 53 behind a over the entire, above a lower aperture region 52 extending glass surface. The upper area and in particular the upwardly exposed and not limited by visually disturbing frame members upper glass plate allow a particularly slim design, which in the field of view of Passengers, hardly disturbing and restricting is felt.

How out FIG. 4 b) in which the open state is shown in perspective, it can be seen, the upper guide 54 has a projection, which projects beyond the rear edge of the respective sliding doors to the rear. This increases the stability, especially shortly before closing the doors.

In FIG. 5 is a section through the middle guide shown in detail. It can be seen that the fixed part 1 has at half the height via a central support 55, on which the rear side, that is to the traction region, a guide profile 56 is screwed. The guide profile 56 is formed as H-profile.

As a counterpart, the sliding door is formed from the upper and lower glass plates 48 and 49, respectively, and these two glass plates are held in the middle by the center support rail 54. Between the two glass plates 48 and 49 remains a horizontal slot, in which the support rail 54 has a corresponding horizontal slot, in which engages the guide profile 56 in the sense of a sliding. In this case, the guide profile has sliders 57 on its leg facing the support rail 54. In the case of the embodiment according to FIG Figures 5 and 6 the upper guide is not designed as a telescopic guide, and it stabilizes the sliding doors only in the horizontal direction. Carrying in the vertical direction is completely taken over by the lower guide.

Since the forward-facing slot in the support rail 54 with the door closed to the people area is facing, this slot should for safety reasons, and to prevent contamination, have sealing lips 58, which close the slot to the people area with the door closed.

The support rail 54 is arranged, for example, at a height H of about 1000 mm above the upper edge of the floor, and such a sliding door can have a very small thickness D of about 50 mm, and still have sufficient stability.

As already noted in the introduction, it is possible to be at such semi-high Sliding door construction for platforms to arrange the light sources in such a sliding door construction and thereby avoid the arrangement of other light sources on the ceiling or at least to support their illumination.

This possibility is schematic in FIG. 6 shown. This is a platform, which is completely closed, that is, for example, the situation in a subway station. The channel of the platform is provided in the ground 60 in the form of a tunnel 61. However, the situation is analogous when there is a closed platform above ground.

It is now possible to arrange light sources 65 at their upper edge in the schematically indicated entire sliding door construction 63. These light sources 65 are directed upwards so that a light cone 64 results in the ceiling 62. Provided that the ceiling does not completely absorb the incident light, this results in an indirect illumination of the person area 20.

The advantages of such constructions have already been emphasized in the introduction, on the one hand in any case, the pleasant feeling of space by the indirect illumination of the ceiling 62 and also to facilitate the care or repair of such a light supply. Since the light supply is arranged at a height of about 2 m at the most, it is possible, for example, to replace, clean or otherwise care for lamps without further ado and without expensive ladders, scaffolding or the like.

In addition, it is possible, as in FIG. 7 is shown to make a targeted such indirect illumination by 62 reflectors 66 are arranged on the ceiling. These may be entire groups of reflectors 66, it being advantageous here that it is possible, in particular in the case of lower constructions of the sliding door 63, to completely direct the light cone 64 away from the personal area 20, and thus to exclude dazzling of the passers-by. In addition, in particular the use of whole arrays of such reflectors allows a very targeted illumination of specific areas in the passenger area 20. It is possible such reflectors 66 with indirect lighting according to FIG. 6 to combine. The reflectors 66 can be mirrors, for example, which can be aligned specifically and differently within the scope of an array. The mirrors can be designed differently, such as matte, glossy, faceted, etc.

In FIG. 8 It is shown how such lamps 65 can be integrated in a cover 12, as discussed in detail above. In FIG. 8a ) the possibility of integrating a lamp in a cover 12 with a flat, slightly inclined to the person area 20 surface is shown. In FIG. 8b ) the possibility of integration with a cover 12 is shown with a convex geometry.

The lamps may be spotlights such as mirrored light sources such as halogen lights, but also conventional headlights, LEDs, etc. The light sources can be provided upwards with means for focusing or for widening the light cone. For example, it is possible, especially when using reflectors on the ceiling, to provide parallelizing louvre grids.

The lamps used may, for example, be clear Osram HCI-EP 150 W / WDL lamps with a light intensity of 13,000 lumens, these lamps being arranged at a height of 185 cm above the floor. Thus, if at least 1-5 such lamps are arranged per cover 12, it is possible to illuminate a typical platform area 20 sufficiently via indirect illumination.

In FIG. 8 In addition, the possibility is shown that the respective lamp head (in a cover several lamps 65 may be particularly preferably arranged side by side) to store according to the needs rotatable. For this purpose, each lamp or a group of lamps 65 is attached to a rotation axis 68 via a lever 69. For example, the lamps can be oriented differently within a cover 12 and the local lighting conditions can be taken into account.

FIG. 9 shows the possibility also shown in the introduction of the arrangement of imaging means in a sliding door construction. As was the case with the arrangement of light sources in the area of the upper edge of the sliding door, the possibility of arranging display means in a sliding door construction is also independent of the further technical features of the sliding door construction (in particular of the sliding door suspension) Etc.). It turns out that it can be of great advantage, in a general sliding door construction of half height, to provide means of representation by means of which it is possible to convey information to passers-by. There are different areas available for this purpose.

For example, there is a first information area A (reference numeral 70) in which a screen, in particular a flat screen, can preferably be arranged behind the transparent area provided there in the stationary area 1. This is essentially at eye level and directly where the eyes of the passers-by are also executed while waiting for the train. It is thus the ideal positioning of a means of representation, for example, for the transmission of advertising, news, information about public transport (delays, etc.).

It is also possible over the entire height of the stationary area 1 in a further information area C (reference numeral 73) to provide means of representation. Here it is possible, for example, behind the transparent surface (glass) to arrange a backlit advertising, but it is also possible to provide simply over the entire height of the glass a flat screen, which transmits temporally variable information or advertising.

Another information area B is given in the edge area of the stationary units 1. For example, in the areas indicated by the reference numeral 72 on the edge. There it is possible to attach warnings about the state of the sliding door, or, for example, status information, such. B. directed to the sliding door arrows when the door begins to close or closing, and / or directed away from the sliding door arrows when the sliding door begins to open or in the opening process. Also operationally relevant information can be provided in the areas indicated by the reference numeral 71 areas of the upper cover 12. There, for example, general warnings that now open the doors to open or the like, but also information about the next incoming train etc.
