Description

 Sliding door for a rail vehicle

The invention relates to a sliding door for a rail vehicle with an outer planking.

A sliding door of the type mentioned is basically known. In this case, a frame is usually made of profile tubes, which is then covered with a planking. The frame is closed, that is, there are provided on all four sides of an outer border of the door and / or on an inner border of a cutout in the door (for example, in a cutout for a window) profile tubes which are interconnected. According to the state of the art, said frame essentially takes over the supporting function of the door, whereas the cladding essentially serves the cladding of the same.

The disadvantage here is that the production of such a door is very time consuming, since a variety of frame profiles joined together, usually welded together, must be. Due to the heat input beyond the risk of distortion of the cream is relatively large, so this may need to be addressed before it can be planked. In addition, such a door is very difficult, on the one hand the frame profiles must have a certain width to be covered with a planking, on the other hand, the wall thickness of the planking must be relatively high, to a sufficient pressure stability or stability against buckling of the door also to ensure in those areas where no Frame profile is provided between the planking. Because of the complicated interior design is dispensed with insulation, so the door is relatively permeable to heat and sound. In the end result, a door according to the prior art has significant disadvantages, which become particularly evident when used in a rail vehicle. On the one hand, the production of such a door in itself is very expensive, yet more expensive because of their high weight and poor thermal insulation nor the operation of the rail vehicle, as an increased drive power and heating and cooling capacity for the car interior is needed.

The object of the invention is now to provide an improved sliding door. In particular, the costs for both the production of this door, as well as for the operation of a rail vehicle, in which such a door is used to be reduced.

The object of the invention is achieved with a sliding door of the type mentioned above, wherein on an outer border of the door and / or on an inner border of a cutout in the door on a maximum of three sides of said border a profile with a width of more than 10 mm is provided between the planking.

Although this does not completely rule out the use of profiles for a sliding door, it does build up without a closed frame. The production of the door is thus considerably simplified, since the time-consuming production of such a closed frame is eliminated. The fact that the interior is designed relatively simple because of the lack of frame, can also be easily provided a heat / sound insulation between the planking. In particular, if this pressure-stable and provided on a large part of the door surface, and the wall thickness of the planking can be chosen low, since the risk of buckling is significantly reduced by the internal insulation. The end result is both the cost of making this door, as well as the operation of a rail vehicle, in which such a door is used, reduced. Such a door thus provides a double benefit.

Advantageous embodiments and developments of the invention will become apparent from the dependent claims and from the description in conjunction with the figures.

It is advantageous if a profile with a width of more than 10 mm is provided between the planking on an outer border of the door and / or on an inner border of a cutout in the door at neither side of said border. The advantages mentioned above are particularly evident.

It is favorable if, in the region of at least 70% of the surface of the door, preferably 80% of the surface and more preferably 90% of the surface, an insulating material is arranged between the planking and positively connected thereto, in particular adhesively bonded. In this way, the sliding door is particularly pressure-stable and has a particularly high sound and heat insulation.

It is advantageous if at least one side of said border is formed by a fold of the planking. In this way, arranged between the skin insulation or even the interior of the door can be closed in a simple manner. By a fold, the stability of the planking is also significantly increased, thereby simplifying the handling of the same in the manufacture of the sliding door. In addition, of course, the stability of the sliding door is increased.

It is favorable if the planking is designed to overlap in the area of the border. In this way, the planking can be joined together particularly well, in particular adhesively bonded or spot-welded

But it is also beneficial if the planking is executed in the area of the border shock to shock. This creates a largely flat surface in the region of the joint. It is also favorable, if at least one side of said border is formed by a strip arranged between the planking with a maximum thickness of 10 mm. In this way, the interior of the sliding door can be closed without the need for a fold of the planking would be necessary. The production of the planking is thus simplified.

It is also beneficial if a profile is placed on the (beveled) planking in the area of the border. In this context, it is advantageous if the profile has a U-shaped, I-shaped, T-shaped or open tubular cross-section, in particular an open rectangular tube cross-section. As a result, a seal for the door can be inserted into this profile or pushed onto this. The assembly of the seal can therefore be done very quickly and therefore cost.

It is particularly advantageous if the sliding door comprises a seal running on at least one edge of the door, which is held by the said planking and / or by an insulating material arranged between the planking and / or by a profile placed on the door. In this way, a frame profile, which in addition to its supporting function of the door should also receive a seal omitted. The structure of the door is thus significantly simplified. In one variant, an already existing planking and / or an already existing insulation used to fix the seal. It is particularly advantageous if a fold of the planking in a recess, in particular groove, engages the seal. In this way, the planking meets a double benefit, since it not only covers the interior of the door but also acts as a holder for the seal. Specially designed for the mounting of the seal profiles can thus be omitted, thereby further simplifying the construction of the door. Alternatively, a profile can be placed on the door, which takes over the mounting of the seal, but has no significant supporting function.

It is advantageous if the seal has at least one hollow region, which engages in a recess, in particular groove, in the door. Because the said hollow areas can be relatively easily and strongly compressed, the seal can be mounted relatively easily and also fills larger recesses in the door.

It is advantageous if the seal has at least one T-shaped or L-shaped extension, which engages in a recess, in particular groove, in the door. This allows the seal to be held in the door with simple technical measures.

It is advantageous if the seal has an extension with a plurality of recesses, in which engage projections of the insulating material. In this way, the seal holds particularly well in the insulating material. In particular, the door can be completed except for the foaming of the interior of the door.

It is favorable if the door remains free of insulating material in the region of the seal. In this way, the mounting of the seal is simplified, or the door can be completed until the assembly of the seal.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts with the same reference numerals or the same Component names are provided, the disclosures contained throughout the description can be mutatis mutandis to the same parts with the same reference numerals or the same component names transmitted. Also, the position information selected in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to a new position analogous to the new situation. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1, 7, or 3.2 to 8.1 or 5.5 to 10.

Fig. 1 shows an exemplary and schematically shown sliding door 100 in a rail vehicle in front view (top picture) and in plan (bottom picture). The door 100 comprises an outer planking 2, which is for example made of a metal sheet, an insulating material 3 arranged between the planking 2, for example mineral wool, gaskets 400 and a window 5. The sliding door 100 is installed in a wall 6 of a rail vehicle 6 (inner wall or outer wall) and can be moved in the indicated direction of the arrow.

Fig. 2 shows a slightly modified form of a sliding door 101 with a slightly different seal 401, which does not terminate flush with the wall 6 of the rail vehicle when closing. Such sliding doors 101 are commonly used in the interior of rail vehicles.

3 now shows a cross section through a sliding door 102 according to the prior art. In this case, a frame with the aid of, for example, profile tubes 7 formed, which is then covered with the planking 2. The frame is closed, that is, there are provided on all four sides of an outer border of the door 102 and / or on an inner border of a cutout in the door 102 (for example, at a cutout for a window 5) profile tubes 7, which interconnected are. According to the state of the art, said frame essentially takes over the supporting function of the door 102, whereas the panel 2 essentially serves to cover the same.

4 shows a further example of a known arrangement with a sliding door 103. Instead of a closed rectangular tube 7, a U-profile 8 or an open rectangular tube is provided on at least one side of the above-mentioned closed frame. It is therefore possible to "clip in" (or "clip in") a seal 402 into the profile 8. Depending on how many sides of a border such a seal 402 is required, several rectangular tubes 7 can also be replaced by the profiles 8 shown ,

5 now shows an embodiment of a sliding door 104 for a rail vehicle with an outer planking 2, wherein on an outer border of the door 104 and / or on an inner border of a cutout in the door 104 at a maximum of three sides of said border profile a width of more than 10 mm between the planking 2 is provided. On at least one side of said border of the door 104, the border is formed as shown by a fold of the planking 2. Specifically, the planking 2 is executed in this example in the area of the border shock to impact. Between the planking 2 an insulating material 3 is arranged and connected to this non-positively, in particular glued.

In this way, an extremely rigid door 104 is created, which is also very light at the same time. The pressure stability is achieved mainly by the insulating material 3, the bending stability mainly by the planking 2. As an insulating material foamed plastics, such as Styrofoam, Styrodur and the like, and for example wood fiber honeycomb cores or else Cardboard honeycomb cores are used. As a planking 2 come in particular steel and aluminum sheets and plates made of fiber-reinforced plastic into consideration. As fibers, for example, glass fibers, Kevlar fibers, aramid fibers, carbon fibers and rock fibers can be used.

If the illustrated completion of the door 104 is provided on all four sides thereof, the insulating material fills practically the entire surface of the door 104. The door 104 is thus not only extremely stable and lightweight, but also has excellent thermal and acoustic insulation.

Preferably, no separate frame profile is provided on either side of the outer border of the door 104 and / or on an inner border of a cutout in the door 104. The door 104 then has very few components, which significantly simplifies storage and manufacturing.

In the illustrated form, the planking 2 is open at the joint. Alternatively, of course, it is conceivable that the planking 2 connected at the joint, in particular welded or glued. Advantageously, such a hollow shell can be made for the time being, which is then filled with an insulation 3. For example, the shell can be foamed with non-pressing plastic foam.

6 shows a slightly modified form of a sliding door 105, in which the planking 2 is designed to overlap in the area of the border. In particular, the sheets can be glued so better or even spot welded.

FIG. 7 shows a further embodiment of a sliding door 106, in which the planking 2 in the region of the border is again designed to overlap. In contrast to the embodiment shown in Fig. 6, the sliding door 106 is now not butt-finished, but has on one side a fold, which encloses a hollow area. This hollow area can for example accommodate a mechanism for moving the sliding door 106, For example, a guide rail or one or more roles. In addition, a drive for the sliding door 106 can be arranged in the hollow region, for example, an electric or pneumatic linear drive. On the right side, the sliding door 106 has a fold in which, for example, a window pane 5 can be mounted.

8 now shows a variant of a sliding door 107, in which a profile 8 is placed on the planking 2 in the region of the border. Specifically, a U-shaped profile respectively an open rectangular tube 8 is placed, which as shown in FIG. 4 can receive a seal 403. In contrast to the embodiment shown in FIG. 4, however, the profile 8 in this case assumes no essential bearing function and can accordingly be made more delicate than a conventional frame profile. In addition, the profile 8 only needs to be placed on those sides of the door where a seal 403 is needed.

FIG. 9 shows a further embodiment of a sliding door 108. In the right-hand area, as in the door 106 shown in FIG. 7, a fold is provided. In the left area, however, the door 108 is closed at least on one side with a strip 9 arranged between the planking 2. The strip 9 is - because it has essentially no supporting function - for reasons of weight, preferably less than 10 mm thick. On this strip 9, a T-profile 10 is placed, on which in turn a seal 404 is snapped or pushed. The seal 404 has in this example two hollow areas, which engages in a recess, here in the grooves formed by the T-profile 10.

Instead of the T-profile 10, a profile with a U-shaped, I-shaped, or an open tubular cross section could also be provided. Of course, these profiles could also be placed on a door 107 shown in Fig. 8.

10 further shows a sliding door 109 for a rail vehicle with an outer skin 2 and a seal 402 extending on at least one edge of the door 109, the gasket 402 passing through said gasket 402 Planking 2 is held. Specifically engages a fold of the planking 2 in a recess, here in a groove, the seal 402. For this purpose, the seal 402 on a T-shaped extension, which in turn engages in a recess, here in the groove formed by the fold of the planking 2. Alternatively, it would also be conceivable that the seal 402 instead of the T-shaped extension has two L-shaped extensions. As can be seen from FIG. 10, a rectangular tube 7 is arranged between the planking 2. Preferably, this is arranged only in the region of a seal 402 and not part of a closed frame for the door 109. However, the above features (fold of the planking 2 engages a recess, the gasket 402 a) are also applicable to a door, the one closed door frame according to the prior art. In this case, the rectangular tube 7 is part of just this door frame, but compared to the arrangement shown in Fig. 3 is slightly offset inwardly to accommodate the seal 402 can.

Fig. 1 1 shows a variant of a sliding door 1 10, in which between the planking 2 in turn an insulating material 3 is provided. In order to facilitate the assembly of the seal 402, a portion of the door 1 10 remains in the region of the seal 402 but free of insulating material. 3

Fig. 12 shows a sliding door 1 1 1, which is very similar to the sliding door 1 10 shown in Fig. 1 1. In contrast, however, the insulating material 3 is guided to the seal 402, or even encloses this partially. As a result, on the one hand, the seal 402 is better kept, on the other hand, so the heat and sound insulation of the door 1 10 is improved.

Fig. 13 shows a sliding door 1 12, which is also very similar to the sliding door 1 10 shown in Fig. 1 1. In contrast, however, a slightly different shape of the seal 405 is provided. This has a hollow region, which engages in a recess, here in a groove, the door 1 12.

14 shows a sliding door 1 13 for a rail vehicle with an outer planking 2 and a seal 406 extending on at least one edge of the door 1 13, in which the seal 406 passes through the between the planking 2 arranged insulation material 3 is held. Specifically, the seal 406 has an extension with a plurality of depressions, in which projections of the insulating material 3 engage. Such an arrangement is produced, for example, by foaming a cavity between the planking 2 when the gasket 406 is already mounted.

FIGS. 15 and 16 show further variants of a seal 400 and 407. The seal 407 closes the door more or less flush and can therefore be used as an edge protector (without an explicit sealing function). On the other hand, the seal 400 is used in an arrangement according to FIG.

Finally, FIG. 17 shows a sliding door 16, with a special seal 408 which holds a window 5. The window 5 is an insulating glass window with two panes 1 1 and a spacing frame 12 arranged therebetween.

Finally, it is noted that the holding portions of the seals 400..408 shown can be provided as continuous profiles, or even only partially. In the latter, for example, pin-shaped projections come into consideration, which protrude into holes in the door 100.1.1 16.

The embodiments show possible embodiments of a sliding door according to the invention 100..1 16 for a rail vehicle, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather also various combinations of the individual embodiments are possible with each other and this Variability due to the teaching of technical action by objective invention in the skill of those working in this technical field is the expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection. In particular, it is noted that a sliding door 100..1 16 for a rail vehicle may in reality also comprise more components than illustrated, or less.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the sliding door 100.1.1, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can be taken from the description.
