Description

The invention relates to a passage for People at the front of a railroad car bound passenger traffic.

To increase the competitiveness of the rails bound passenger traffic becomes both driving comfort as well as the speed of the ones in use Trains continuously increased. With increasing speed under the individual construction elements are always larger Conditions. The forces that apply to the individual Attacking structural elements are essential rose, e.g. B. due to the high pressure fluctuations, such as on the encounter of high-speed trains free route, when passing through a tunnel and especially when encountering two high speeds trains in a tunnel. One of the corresponding off against pressure fluctuations leadership must be with windows, doors and. Like. Be provided.

Particular attention is paid to those construction elements that are not like windows and doors the side front of a wagon either cannot be opened or can only be opened when the wagon is stationary, the both at standstill and at normal Operating speeds can be opened and closed have to. Here are the doors in the forehead area in particular Wagons affected by the passage of people from to guarantee one wagon to another. Of the The passage for the people is in turn in the to form substantially pressure-tight, on the one hand to Track superstructure a step surface is provided and further a flexible connection between the strings  Wagons must be provided that are both liquid-tight, as well as must be essentially gas-tight to Tensile loads for the people using the passage to avoid.

However, these doors in the front area of a wagon must also have the additional property that they both as the first door of a first wagon and as last door of a last wagon used in a train can be. For this purpose it is known that in Car body is provided with an inflatable seal when using the wagon as a first runner or as End runner at the corresponding end door with compressed air can be applied. For security reasons, a such passage, which is usually two against and apart doors, yet another Have protection. For this further hedging is a crossbar can be placed inside the wagon, on both sides the doors are stored. According to DE-A1 40 19 815 can this cross support is also articulated on one side of the wagon be and are designed to be telescopic, for example.

When used in the first or end car are the Such stresses on the front doors big that it is too with pressurized seals Deflections and thus lead to leaks. In order to avoid such deflections, it is in accordance with EP-A1 91890072.1 known, both on the car body and to provide hooks or receptacles on the doors so that the closed doors also in the transverse direction to the opening and Closing movement of the same are fixed.

To secure the door against unauthorized or unintentional opening is another closure  provided that either connects the doors to each other, so that an opening by moving them apart is no longer possible or a fixation on the wagon body he follows. These fixations are usually made with your own Keys or tools, e.g. B. triangular or square key, performed.

AT-B 315 902 describes a wagon that arrives at the front side has sliding doors. These doors will be in the closed position either via a stop or held in the same with a hook. This Stop or hook is provided on a hollow cylinder, which on a cylin provided on the wagon body outer sleeve is guided. This cylindrical sleeve has two spiral through grooves and has a pin inside, the pin through the spiral grooves through with the outer cylinder connected is. If the step is now folded up, so the pin is moved and rotated over applied to the spiral groove so that twisting of the stop or hook. Such Device causes relatively high frictional forces due to the Guide the pin in the sleeve and the cylindrical Hollow cylinder over the sleeve, making the one Railway operations do not require high operational reliability is guaranteed.

The object of the present invention is to another door security device against the passage of To create people who function automatically, if such doors are the first door or the last door of a train. Another job of The present invention is that the unhindered passage guaranteed when the door is open  must be without getting stuck or stumbling through people.

The passage according to the invention for people on the Front of a wagon for the railbound Passenger traffic with at least one, especially two, movable from an open to a closed position Door (s), preferably sliding door (s), with step surfaces, which are formed with partial treads for the transition can be arranged from one to another wagon and at least a first partial tread surface articulated on the wagon is and with at least one spring element to the door is foldable, and in particular another partial step Surface can be moved and folded up in the longitudinal direction of the wagon is essentially that the first Partial tread has a recess in which folded up position of the first partial tread and at Closed position of the door a projection of the same Wagon exterior, especially a bolt, protrudes. In the Arrangement of the wagons as the first or last will be at the first or the first part of the last door tread and also the further partial tread folded up. This process must be carried out in each case be so open, neglecting the same it is clear that a correction is made immediately. The fact that a mutual engagement of the door and Footboard when the partial step is folded up is given, the desired security Fixation. Because in the part tread surface a recess is provided, and on the Door arranged with this cooperating projection is not a stumbling block as it is caused by a front jump would be given on the tread, conditional, whereby furthermore getting stuck on the ledge, which is in the  essentially transverse, especially normal, to movement direction of the door extends, is easily avoidable.

The recess extends in the opening direction of the Door so that a limited opening of the door from the Closed position is possible, work, which to adjust the wagon from its position as first or last wagon in a middle position too partially done from the inside, since the operator the Door can open and limited by the emerging Then open the step surface so far outwards and can tilt down that the passage of this Side of the wagon is given to another wagon.

Has the ledge in his adjacent to the door Area a rubber-elastic element, whose cross cut is larger than that of the projection, so is at Folding up the partial tread surface will damage the Partial tread and in particular the door that in the Rule is constructed from softer material than that Partial tread, particularly simply and effectively avoided, without taking additional precautions on the doors must be, which may become a limitation the possibility of moving the doors.

Is the recess on the articulated area of the opposite the first partial tread area seen and open transversely to the folding direction, that is the Possibility to hook up with a heel, especially small with a structurally simple design.

Instructs the first partial tread on the recess the area opposite the area being walked on hinged flap with a filler, which in  corresponds essentially to the recess and at folded down first partial tread the recess fills out, so through the hinged flap in the folded up state of the first partial tread Recess can be easily released and functional position of the partial tread the recess completely be met so that any hindrance in use the same, even with an oversized recess, safely is excluded.

If the recess has one, in particular at least partially, from bottom to top in the functional position of the the first partial tread surface has a narrowing cross section, so either by chamfering the edges The user can get stuck or get stuck reverse training an exact completion of the Recess achieved by the filler particularly easy become.

If the filler is resiliently held in the recess, then the recess is released automatically or also automatically completed, which makes it particularly easy Conversion of the first partial tread from a special one safe area to be walked into in a security device can be done.

Does the door have the projection on that area which only in the closed position with the other Door or with a recording in the wagon comes into contact, so can even with a particularly large transverse extension of the A slightest limitation of opening and opening Closing movement of the doors can be achieved because both the Projection as well as those areas of the door that the Actual locking function, the greatest way  can cover.

The ledge points you from the door to his End area continuously, in particular tapered, cross section on, so is a special the first partial tread surface snaps securely into the projection guaranteed because no or no discontinuous Resistance when folding up the first partial tread against the door or doors.

If each door has a head start, it is a redudant one Protection given so that, for example, at a Malfunction of a tab the second tab could still perform the intended function.

There is a recess in the first for two projections Partial tread is provided, so it is surprising simple way the possibility of hooking has been minimized with a paragraph, while the Recess with a particularly simple design Filler can be covered.

Has the first tread in the area of the recess Bevel, on the one hand, as is known per se, the first step on another step particularly seamless, with further through the Bevel the recess as such here too particularly easy sliding over the edges of the Recesses is possible.

In the following the invention with reference to the drawings explained in more detail.  

Show it:

Fig. 1 a passenger transition between two carriages in side view,

Fig. 2 sliding with folded up first tread surface,

Fig. 3 shows a schematic representation of the sequence of movement of the two treads

Fig. 4 shows a detail of the sliding doors and the first tread in an enlarged view and

FIGS. 5 and 7 shows a detail of the two treads in the section, and

Fig. 6 shows a detail of the two treads in plan view.

In the example shown in Fig. 1 persons transition, the end faces 1 and 2 of carriages 3 and 4 are provided with support elements 5 and 6, with which the membranes are 7 or 8 movably connected. At the end of the membranes, frames 9 and 10 with coupling elements 11 and 12 are arranged, which enable the frames to be positioned exactly with respect to one another. The frames are extended on both sides of the wagons in the area close to the track and each carry a bearing 13 , 14 for further partial treads 15 , 16 which are designed as flaps. On the transition bridge 17 in the functional position, the further treads rest on an abutment, and there are first partial treads 18 , 19 , which are designed as ramps, articulated on the car body and lie on the further partial treads 15 and 16 in the use position. If the wagon is used as a first runner or end runner, the first or last end face must be changed by supplying the membranes including the frame and folding up the first and further partial treads.

In the passage shown in Fig. 2, the sliding doors 20 and 21 are shown in the closed position. The first partial tread surface 18 is folded up and held resiliently against the sliding doors 20 and 21 via spring elements 22 , 23 . The partial tread surface is articulated on the car body via hinges 24 . The further partial tread surface, which would cover the first partial tread surface when folded up, is not shown. The first partial tread has a recess 25 , in which a projection 26 of the door 20 , u. between a bolt, engages. The recess is not closed in itself, but is open at the top. As can be seen particularly clearly from this illustration, the sliding doors can only be opened according to the length 1 of the recess in the gap. Depending on the construction, the second sliding door 21 does not require any additional movement inhibition, since there is generally a mutual positive control of the doors for the symmetrical movement of the two sliding doors. Thus, the sliding door 20 can be moved accordingly to the length of the gap 20 , the second sliding door is also forcibly moved by 80 mm, so that a gap of 160 mm is created, which is sufficient to actuate the first tread from the inside from the wagon.

The movement sequence of both the first and the further partial tread surface is shown particularly clearly in FIG. 3. The functional position is shown as a continuous line with solid lines, whereas single-dot lines are shown in dash-dotted lines until the rest position is folded up.

The first partial tread surface 18 has a beveled area 27 with which it rests on the further partial tread surface 15 . If the partial tread surface 15 is now opened into position I, the first partial tread surface is also forcibly opened and held resiliently against the sliding doors by the spring elements 22 and 23 shown in FIG. 2. From position I, the further partial tread 15 can be moved in the direction of arrow a, so that the folded-up further partial tread is arranged adjacent to the first partial tread 18 , as can be clearly seen from position 11 .

As seen from Fig. 4, both doors can have 20 and 21 has a projection 26. This projection is a tapered bolt starting from the door and carries at its end adjacent to the door a rubber-elastic element 28 , u. in the form of a disc. The tread is therefore not directly on the door, so that mechanical damage to the door, which is usually made of a softer material than that of the tread, does not occur. The protrusion can extend beyond the first tread when the same is folded up. However, it is only necessary to ensure that the sliding doors are reliably prevented from moving. A separate recess can be provided for each projection 26 , or, as shown in dashed lines, a continuous recess 29 can be realized. Such a continuous recess has the advantage that there is even less danger of hooking with a shoulder.

In FIGS. 5 and 6, the first step plate is shown in its folded-down position and is on the other footboard 15. In the recess 25 , which is arranged in the region of the bevel 27 , a flap 30 is provided, which essentially serves as a filler for the recess 25 and is articulated on the first partial tread surface via hinges 31 . As can clearly be seen from the gradation 32, the recess has a cross section which tapers from bottom to top. By appropriate design of the hinges 31 , the flap 30 can be held resiliently in the position filling the recess. When the step is folded up, the flap is then pushed out of the plane of the step by the projection.

As shown in Fig. 7, the recess 25 itself can also have a bevel 33 , so that the recess has a cross-section widening from bottom to top, so that in the functional position of the partial tread surface hooking with a shoulder or the like is particularly easy to avoid .

Although not shown in the drawing, is for the Overall function of the sliding door is even more special Meaning that inflatable seals are provided which allow the sliding doors in the wagons to be sealed. It is also of particular importance that both the doors as well as the car body carry hooks or mounts that a transverse movement of the door in the closed position prevent.
