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.

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, wherein both the stationary areas and the sliding doors have a height in the range of 1-2 m or even to 2.5 or 3 m above the floor of the passenger area and above no means for separation between the passenger area and track area are arranged

The solution to this problem is achieved in that the sliding doors are designed to be free-carrying and are movably guided in or on the stationary areas that for this purpose an upper and a lower guide are provided, wherein a guide is designed as a roller guide or as a ball linear guide, and a Leadership as Sliding guide or is designed as a roller guide.

The essence of the invention is thus to propose a double guide in a self-supporting sliding door, which ensures increased stability and at the same time high reliability.

According to a first 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, and / or the upper guide substantially at the upper edge or 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 can observe the retraction.

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, for example with worm gear, and that the drive drives a toothed belt drive roller, which is arranged offset via toothed belt pulleys from the main direction of the belt down or up. 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 required, it proves to be advantageous, designed as a slide guide upper guide as an at least three-part telescopic guide form, which has a fixed to the stationary area guide profile, a firmly connected to the respective sliding door guide rail and a respect 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.

Another embodiment of the upper guide is characterized in that the upper guide is arranged substantially at half the height of the sliding door, wherein the above the upper guide arranged portion of the sliding door made of glass or other substantially transparent material is formed. In particular, if then also this completely or partially transparent plate is formed with a substantially exposed top edge results in an elegant construction, which exerts on the passengers a much smaller restrictive effect than constructions in which a frame portion is provided at the top.

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 according to the invention by a special embodiment of the bottom plate on which the stationary areas is arranged, respectively which forms part of the inpatient 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 transfer and positive connection between the base plate and anchor bolts 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.

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 is replaced after applying more insulating spacers (for example, washers as mentioned above) under With the help of nuts or similar 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 sliding door construction according to the invention and of the method according to the invention for mounting such a sliding door construction are described in the dependent claims.

WAYS FOR CARRYING OUT THE INVENTION

FIG. 1a) shows a perspective view of a sliding door construction which is intended to serve as an exemplary embodiment of the present invention. The embodiments which are described in the following, but should be consulted only for illustration, not to limit the scope, as defined in the claims.

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 constructions, as one of them is shown in Figure 1a), 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 fixed parts 1 is made of aesthetic For example, a transparent area 4 arranged. 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 is connected, inter alia, to a total control of the entire system of sliding doors on a platform, so that a coordinated opening process or closing of all sliding doors at the right moment, that is at the correct position of the train, can be guaranteed , The sliding doors 2, 3 are partially equipped with transparent areas 5.

In Figure 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 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 that behind the baffles 25 (see 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 approximately 1700 mm (depending on the clear width of the door), since it has a guide rail 18 due to the cantilevered design, which rearwardly over the actual width of the door protrudes. 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.

Figure 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 in the ground by two rows of anchoring elements 7, the first row of anchoring elements being 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 apart by approximately i = 210 mm ,

The drive region is shown in detail in the following FIGS. 2 b) -e). In Figure 2 b) is a sectional view. From this it can be seen that attached to the bottom plate 6 support columns 34, a horizontal guide member 19 am Fixed part is attached. 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 toothed belt deflection rollers 32 are arranged above this toothed belt drive roller, which should be discussed in connection with the figure 2d). 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

FIGS. 2c) and d) show two views of the drive region 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, 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, ie horizontal drive motor with worm gear, toothed belt drive roller 31 with deflection over two toothed belt deflection rollers 32, allows a particularly compact design, and the use of a belt for driving proves to be particularly robust.

From the perspective view according to Figure 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 shown in FIG 2 e), it is also possible to form this guide element 19 as 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 better seen in Figure 2f). 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 somewhat backwards over the door, as shown in Figure 1 d). 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. Figure 3a) shows in detail the floor area of the construction. A bottom plate 6 is anchored with fastening elements 7 in the platform material 40. 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. About the above ground level upwardly protruding ends of the fasteners is now the Base plate 6 is placed, wherein the fastening elements 7 pass through corresponding provided in the bottom plate 6 holes 44, 45. Insulating spacer elements 42 are also provided between the bottom plate 7 and the bottom, wherein, for example, as shown in FIG. 3 a), they may be formed in the form of insulating washers 42. 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. The material of the coating can be, for example, the product Rilsan® from Atofma (DE), such thermoplastic PA11 materials can be used, for example, in the fluidized bed process, in the electrostatic spray process, by powder spraying or the like. 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 filler 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 it on the one hand has sufficient strength for holding, and on the other hand, a brittleness, which allows removal during disassembly again. 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 can be seen in Figure 3b) is designed so that a sufficient tolerance circle p of 10 to 20 mm is formed.

In detail, such a bottom plate is shown in FIG. 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 At the moment, the doors can open and close automatically (this is especially necessary for the nightly retrofit procedure, as the trains leave the next morning). This also means that during the installation phase during the day already installed doors already work automatically.

FIG. 5 shows a further exemplary embodiment of the invention. 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. 5, the upper guide is correspondingly arranged at half the height, and glass plates 48 and 49 are respectively arranged above and below. The arranged in the lower region lower guide is designed the same as in the above-discussed embodiment. 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 upper glass plate, which is exposed upwards and is not delimited by visually disturbing frame elements, enable a particularly slim construction, which is hardly distracting and restricting in the field of vision of the passengers.

As can be seen from FIG. 5 b), in which the opened state is shown in perspective, it can be seen that the upper guide 54 has a projection which protrudes to the rear beyond the trailing edge of the respective sliding doors. This increases the stability, especially shortly before closing the doors.

FIG. 6 shows a section through the middle guide in detail. It can be seen that the fixed part 1 at half the height via a central support 55th has, on which the back, that is to say to the train area, 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 the case of the embodiment according to FIGS. 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.
