Double sliding door for a touring car of a rail vehicle

The invention relates to a double sliding door for a touring car of a rail vehicle, in particular a front wall door, with two each longitudinally movable by means of a running rail on a support rail guided door leaves, which open and synchronously by means of a coupling connecting the door leaves are to be closed, the opening by pivoting an indirectly on a compressed air cylinder a electro-pneumatic device acting handle is to be effected.

Such a double sliding door is known at which each of the two door leaves an electro-pneumatic device, also known as an opening aid is assigned, so that there are two such facilities. Also te * every wing of the well-known double sliding

YHtHO «suffered

for its own tour. The opening "movement beij the door leaf is in this "well-known double schio-

j door by operating one or both handles

initiated and synchronously ge during opening

controls. The door leaf opening is controlled via an electro-pneumatic time switch valve with pulse contact. After a certain delay time of, for example, 13 seconds ) the two are automatically vented

Air cylinder so that the door leaf due automatically close an existing mechanical locking device.

The known locking device has a memory spring designed as a spiral spring which when opening the respective door leaf is tensioned and a force running in the closing direction exerts on a guide roller guided on a roller track sloping in the closing direction.

This known double sliding door has the disadvantage J that the desired synchronous return movement

is often not achieved. This disadvantageous effect arises on the one hand due to the separate Execution of the two door leaves each with their own guide and opening device and on the other hand as a result of different frictional forces, which for example by seals and the like arise.

A lack of synchronization in the return movement of the two door leaves from their opening

stelliing in particular occurs in their closed position then intensified when the touring car drives through a curved track and is temporarily in a certain incline. In such a case, one door leaf often closes, while the other door leaf is not just delayed compared to the first door leaf, but at all does not come into its closed position *

Its synchronous movement and complete closing However, both door leaves are urgently required to ensure the necessary Heisekonifort, otherwise travelers who want to pass through the double sliding door with luggage, for example and therefore need in full passage width, at least have to leave their luggage to the door of Can be opened completely by hand, or if the door is incompletely closed due to drafts, noises etc. are annoyed, so that in the latter case, too, manual closing is necessary.

Another disadvantage of the known double sliding door is that if the electropneumatic fails Drive due to failure of the compressed air and / or the electrical voltage of each door leaf has to be opened by hand.

Finally, another disadvantage of the known double screen door is that a subsequent Experience has shown that installation in a trolley is associated with great difficulties. This

arises from the fact that the individual parts the "known double sliding door, such as its compressed air cylinder, its guides, etc., individually can be mounted in the car body and assembled to form the double sliding door, which is due to assembly inaccuracies often result in malfunctions.

Such malfunctions also result relatively often from the electrical cable connection between the longitudinally displaceable door leaf and the Vacenkasten that is fixed to this, as at the well-known double sliding door as a cable connection a tow cable provided with a protective hose serves, which breaks easily, especially at low temperatures, and thereby leads to a short circuit can lead.

In order to avoid the lack of synchronization behavior described above, one is therefore already switched to providing a double sliding door with a coupling connecting the two door leaves, which is designed as a rope, belt, chain, rack and pinion coupling or the like. Due to such a coupling is achieved in this known double sliding door that the opening and closing movements must take place completely synchronously. Both movements are in this known double sliding door by an electro-pneumatic device with a single air cylinder causes its piston

• · III

depending on the direction of movement of the door leaves from one or the other side is pressurized with compressed air.

Although there is a lack of synchronization between the movement of the two door leaves this known double sliding door is fixed, are also considerable in this door construction Disadvantages, which oppose a satisfactory use in heating wagons of rail vehicles.

A major disadvantage arises from a failure of the air supply or the electricity. It is felt to be particularly uncomfortable that the electro-pneumatic device of this known Double & sliding door not only takes care of opening but also closing, so that in the event of failure of the Energy supply in any case, the door is to be closed again by hand without this taking place automatically, which, as already stated, is regularly not or only imperfectly carried out will.

Moreover, this known double sliding door also has the disadvantage that numerous individual parts have to be built into the travel vehicle during assembly and then connected to form the double sliding door, which is also the case in particular a subsequent assembly is to be regarded as disadvantageous and especially if it is the Assembly personnel are not specialists, very often leads to operational disruptions due to the circumstances described above *

The invention is based on the object of improving the known sliding doors while avoiding their above disadvantages, and of creating a generic double sliding door, the door leaves of which can always be moved reliably and synchronously, with automatic closing guaranteed in each case even if the power supply for the double sliding door fails should be ν: Δ high operational reliability should be guaranteed even with the simplest possible subsequent installation.

As a solution to this problem, the invention provides that one person is known for each door leaf mechanical locking device provided i &i;, each one ramp-like, inclined in the closing direction of the door leaf and with the support rail Permanently connected guide track for a guide roller connected to the door leaf and one at the opening of the door leaf has tensioned storage spring acting on the door leaf in the closing direction, wherein the mechanical locking device together with the support rail, the running rails and the for open serving air cylinder of the electropneumatic Device is designed as a compact structural unit.

Due to the design according to the invention, there is therefore not only a double sliding door which in any case, i.e. even if the power supply fails, the door automatically after opening again closes, as this is urgently desired for the reasons set out above, but there is always a synchronous movement of the door

The sash is present both when opening and when closing. In addition, the erf liiaungägewässer works Double sliding door with the greatest operational safety, even when retrofitted in a touring car, with the Ilontage there is no difficult one, only Alignment work that can be carried out by specialists and the like is required because the entire device is designed as a compact unit that only is to be installed in the touring car by screwing the mounting rail to the car body.

In an advantageous development of the invention, the electrical lines are electro-pneumatic Opening device of a door leaf having a swivel handle attached to the door leaf feat or arranged sunk in this, and fixed to one on the running rail of the door leaf Attached cable holder out to which a helical cable is connected, which at its free end is connected to a connection plate to be fastened to the stationary car body. Because of a Such a design of the double sliding door, a construction was created in which the electrical cable connection between a longitudinally displaceable Door leaf on the one hand and a fixed connection above the guide of the door leaf in the car body on the other hand is easily solved, because due to the fixed cable connection on the door leaf, i.e. between the handle and the cable holder attached to the running rail on the one hand and the flexible cable connection, designed as a spiral cable, between the longitudinally displaceable one

Door leaf and the stationary car body on the other hand, cable bridge, as it was "in the previous embodiment often happened with a tow cable, are no longer to be feared.

Due to the design of the double sliding door according to the invention, only a single handle is preferably provided on each of its two sides, so that on the whole not four, but only two handles are present as was customary up to now. The two handles can be arranged on one of the two door leaves, in which case they are then opposite one another. This configuration has the advantage that the particular can not be with a handle vex-Höhene door particularly easy to be configured It HTIN ₁ because with him not only on the handle itself, but also to the continued leading from the handle connecting lines omitted.

In an embodiment of the invention, however, it is often preferred that one on each door leaf Handle is arranged, in which case the two handles are diagonally opposite one another, as it were, so that, for example, on each side of the double sliding door on the right or left Handle is available. Such training is therefore usually preferred because it is already comfortable for the travelers due to the corresponding habituation, the handle in each case on the same side of the double sliding door.

(for example on the right-hand side), - regardless of whether you open the double sliding door from one or the other want to open the other side. This advantage is considered to be so remarkable that the additional Expenditure for the electrical installation in the second door leaf and a second coiled cable gladly is accepted.

To achieve the desired compact design and to create a structural unit consisting of the drive and guide devices, the compressed air cylinder at its end portion in itself. known way have flange-like approaches that

^{m are} connected to a bracket firmly attached to the mounting rail, the piston rod preferably acting on a driver connected to the handle of a door leaf. This already results in a sub-assembly consisting of a support rail, compressed air cylinder and running rail, as well as the additional auxiliary parts attached to these parts, such as, for example, the Mit, which cooperates with the piston rod and which is attached to the running rail

holder, the cable holder, which is also attached to the running rail, etc.

In contrast to the previously known mechanical locking devices for such sliding doors whose storage spring was designed as a spiral spring, the storage spring is the subject matter of the present Invention preferably a helical spring which is guided on a rod. It is preferred the helical spring at one end connected to one of the running rails in question

Guide block for the rod and supported on its other Eüda on a 'fork head, which is articulated attached to one end portion of a 3 L-shaped lever is, which carries the guide roller at its other free end portion and in his Vertex is rotatably attached to the running rail in question. Apart from the opposite Spiraloder Leg springs brings the arrangement according to the invention with a significantly longer service life Helical spring has the advantage that even in the event that, in rare cases, a break the spring should occur, the fractions would remain on the guide rod without they hinder the function of the system or the closing force of the mechanical closing device significantly affect.

The coupling connecting the door leaves is preferably a cable drive in a manner known per se formed, the pulleys of the rope rotatably on the support rail and the free End sections of the rope are each attached to a running rail. This configuration too again shows that all parts of the Doypel sliding door in the most compact design are combined in a structural unit, which can be installed or exchanged as a whole in a touring car if this appears necessary during repair work.

Of course, instead of a cable drive, a belt drive or chain drive or even one could also be used Rack coupling or the like can be provided,

however, in the present case, a cable coupling has proven to be particularly simple, inexpensive and reliable proven, so that more complex parts such as chains, racks, gears and the like are deliberately omitted has been.

It is preferably provided that the cable coupling has a tensioning device and an elastic one. Link is provided so that the rope is always taut and does not sag.

To avoid trapping passengers who are still between the during the closing process Are door leaves or want to step through the door at this moment, is in a preferred embodiment the invention provided at least one door leaf with a known reversing device, wherein preferably in a recess of the relevant door leaf triggering a reversing movement known pressure wave switch can be arranged, which via a connecting hose with is connected to a pressure rail attached to the front edge of the door leaf.

The invention and preferred refinements of the invention are illustrated below using an exemplary embodiment further explained with reference to a drawing. It shows:

Fig. 1 is a side plan view of a

Front wall double sliding door for a sea car of a rail vehicle when closed,

Pig. FIG. 2 shows an enlarged illustration of a section of the double sliding door according to FIG Figure 1 in a sectional view according to the section line II-II and

3 shows an enlarged partial illustration of the bordered with a dash-dotted line and denoted by the reference symbol III. Section of the double sliding door according to Figure 1.

The drawing shows a double sliding door, designated as a whole by 1, as a front wall door for a touring car of a rail vehicle. The double sliding door 1 has two door leaves 2 and 3, each with a running rail 4 or 6 in the direction of the arrows 7 and 8 are guided longitudinally movable on a support rail 9. The door leaves 2, 3 are through a Coupling interconnected so that they can be opened or closed synchronously. the Coupling is designed as a cable drive and consists of a cable 11, which is driven by pulleys 10, which are rotatably attached to the support rail 9, is deflected. The rope 11 is at the point 12 attached to a driver 13, which in turn is firmly attached to the running rail 4. Another End section 14 is connected to a driver 16 fastened to the running rail 6. One Tensioning device designed as a tensioning screw 17, together with a tensioning device consisting of disc springs 18, provides elastic member for the fact that the rope 14 is always tensioned and does not sag.

Opening the double sliding door 1 or its door leaves 2, 3 is done by pivoting a handle 19 or 19 "in the direction of arrow 20 or 20 '. The handle 19 or 19 * acts indirectly

on a compressed air cylinder 21 of an electro-pneumatic Setup, as this is explained in more detail below.

A mechanical locking device is provided for each of the two door leaves 2, 3. The mechanical Closing device points one down in the closing direction of the relevant door leaf 2 "or 3 inclined, ramp-like guide tap 22 "or 23, -which the guideways 22, 23 are each firmly connected to the support rail 9 by brackets 24. In addition, the mechanical locking device for the door leaves 2, 3 has guide rollers 26 "or 27, which roll on the guideways 22 ″ or 23. Finally, belong to the mechanical locking device nor storage springs 28 and 29, which automatically when the respective door leaf 2 or 3 is opened be tensioned and then exert a force acting in the closing direction on the door leaves 2 or 3. The storage springs 28, 29 are each guided on a rod 31 and 32 and are supported on their one end in each case on a guide block 33 or 34 · for the rods 31 and 32 as well as on their other End on a fork head 36 and 37, respectively is articulated to one end portion of an L-shaped lever 38 and 39, respectively. The L-shaped levers 38 and 39 each carry the guide roller 26 and 27 at their other free end section and are each rotatably attached at their apex 41 and 42 to the respective running rail 4 and 6, respectively.

It can be seen that the mechanical locking device 22 to 42 together with the support rail 9 and the running rails 4, 6 and the compressed air cylinder 21 of the The electro-pneumatic device forms a very compact unit, which together with the hangers 43 or 44 for the door leaves 2 or 3 to be installed as a whole in the travel vehicle or - for example at necessary repair work - must be replaced. Such a drive and guide unit In addition to simple assembly of the structural unit in the car body 46, there is also the advantage immediate readiness for operation after installation, without the need for expensive and complicated T5in- or alignment work is required.

The electrical lines 47 of the electro-pneumatic opening devices are each housed in a door leaf, which can be operated with a handle 19 »19 'is provided, it being in the one shown Embodiment is therefore the door leaf 2. The permanently installed electrical lines 47 lead to a snap switch element 48 and from there to a cable holder 49 firmly connected to the running rail 4 We & delkabel 51 connected that to his other the free end is connected to a connection plate 52 to be fastened to the stationary car body 46.

From the drawing it can be seen that only the door leaf 2 is provided with handles 19 »19 ', while the door leaf 3 has no handles. Instead it would of course also be possible

to arrange the handle 19 'on Türflücel 3 so that in one such case on each side of the double sliding door there would be a swivel handle on the right-hand side, like this one for operation may be desirable.

With regard to the inclusion of the compressed air cylinder 21 in the structural unit, it should be pointed out that the compressed air cylinder 21 has at its one end portion flange-like projections 53, which with a the support rail 9 fixedly attached bracket 54 · connected are. The piston rod 56, on the other hand, acts on one connected to the running rail 4 of the door leaf 2 Driver 57

In order to prevent a person from being trapped between the door leaves 2, 3, there is a reversing device intended. For this purpose, a pressure wave switch 58 is located in a recess in the door leaf 2 provided, as can be seen in particular from FIG. The pressure wave switch 58 protrudes a connecting hose 59 with a pressure rail attached to the front edge 61 of the door leaf 2 in connection, so that if the front edge 61 is only touched lightly, it will open again the double sliding door 1 is executed. Of course, it could also be on both front edges instead 61 of the door leaf 2 and 62 of the door leaf 3 can be arranged a reversing device, which both could act on the pressure wave switch 58, so that a repeated opening of the door both would be initiated when the leading edge 61 is touched and when the leading edge 62 is touched.

A is used to accommodate the pressure wave switch 58 Housing 65 embedded in the door leaf 2, which apart from the lines 4-7, which from the connection plate 52 to the pressure wave switch 58 and the snap * Switching element 64 lead in the handle fitting 66, also contains the known door lock in the manner of a Basquill lock, which in a known manner at desired door closure at a stop 68 of the support rail 9 via a locking bar 69 an actuating cam on the swivel handle 19 «19 * blocked, so that the handles cannot be moved and an opening impulse cannot occur.

Opening the door leaves 2 ₉ 3 is done by swaying

one of the two handles 19, 19 'in the direction of arrow 20 or 20', whereupon In the already described manner by means of the compressed air cylinder 21 or its piston rod 56 an opening of the door leaves 2, 3 coupled to one another is effected. A time switch valve, not shown, vents the pressurized air after a certain, adjustable delay time of about 13 seconds Cylinder, whereupon the closing movement is initiated automatically by the storage springs 28, 29. The guide rollers 26, 27 roll on their guide track 22 and 23 against the arrows 7 or 8 back to their starting position shown in FIG.

The particular advantage of the double sliding door according to the invention lies in the fact that when open

Right maintenance of the already known SynöxxT-oüisäulen zwioChcii dsa Bswsguugtii clsr beldezi door leaves 2, 3 in each case a closing movement takes place automatically without the need for a special operation by an operator. Another notable advantage lies in the fact that the new double sliding door, or in particular its Drive and guide devices, as well as their fastening means, are designed in the most compact Veise as a structural unit that is not just simple in one Are to be installed in the initial equipment of a touring car, but also in particular in the case of subsequent equipment with such double sliding doors as well as in the Quick repair cases are to be exchanged as a whole. Ultimately, operational safety is not only better known than the preassembled base as such. Double sliding doors increased considerably, but there is also a considerable amount Increase due to the unchangeable, inherently fixed assembly of the electrical lines, which when opening and closing together with the door leaf (s) be moved, the movable connection to the fixed car body by a corrugated cable takes place, which is ideally suited for such movements, so that this does not cause any malfunctions go out.
