Description

FIELD OF THE INVENTION

The present invention relates to a gangway cover for the front covering of a gangway device intended to be arranged between two vehicle parts connected to one another in an articulated manner, in particular wagons or wagon bodies of rail vehicles.

STATE OF THE ART

Vehicles for transporting people, such as trains or trams, often have individual vehicle parts in the form of wagons or wagon bodies which are connected to one another in an articulated manner. In order to enable users of these vehicles to switch between the individual vehicle parts while the vehicle is in motion, transition devices are provided which are arranged between the vehicle parts.

The respective transition device is either attached to a vehicle part and this vehicle part is connected to a second vehicle part without a corresponding transition device, or the transition device has two parts, one part of the transition device being arranged on each vehicle part. The two parts of the transition device are suitably connected when used.

If two vehicle parts are connected to one another, the interior of the vehicle part is protected from environmental influences, since nothing can get into the interior of the vehicle part through the transition device and access or passage openings of the two vehicle parts are connected to one another by the transition device and are therefore not accessible from the outside. However, if two vehicle parts are decoupled from one another, both vehicle parts have an access opening that is accessible from the outside, through which environmental influences such as rain or snow or the like can get into the vehicle interior and possibly cause damage. This is disadvantageous since, on the one hand, damage can be caused and, on the other hand, vehicle parts, in particular wagons, cannot be left unprotected individually. In practice, it is therefore common for the vehicle part to be housed under a canopy or in a garage, although the interior of the vehicle is then still exposed to a certain degree of soiling, for example from dust. Alternatively, doors or roller blinds are also provided in the prior art, which are used to cover this passage opening. Doors, however, make it difficult for passengers to change between the vehicle parts and blinds are usually unstable or precise adjustment to the passage opening is difficult.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide a transition cover which overcomes the disadvantages mentioned above.

PRESENTATION OF THE INVENTION

In order to achieve the stated object, a gangway cover is provided for covering the end face of a gangway device intended to be arranged between two vehicle parts which are articulated to one another,
wherein the transition cover has a front side and an edge section which essentially completely surrounds the front side and protrudes from the front side with a directional portion normal to the front side, wherein the transition cover is adapted to be slipped over a front side of the transition device.

The two articulated vehicle parts are, for example, vehicle parts of rail vehicles, in particular two wagons or wagon bodies of a tram or a train or the like.

The transition device is used to enable passengers to switch between the individual parts of the vehicle while driving. This means that it is not necessary to leave the vehicle to get to another part of the vehicle. The transition device thus connects two different vehicle parts to one another. Accordingly, both the vehicle parts and the transition device must have an access or passage opening through which people can easily pass. Since the vehicle parts can be releasably connected to one another, the passage openings of the vehicle parts or the transition device are openly accessible when the two vehicle parts are not connected to one another and are accordingly exposed to environmental influences. In order to prevent damage from external influences such as rain or snow as far as possible, the transition cover is provided according to the invention.

As explained above, the transition device can consist of one part that is attached to one of the two vehicle parts remains when the latter are separated. Or the transition device can consist of several, in particular two, parts, with one part remaining on each vehicle part when the latter are separated. In the following, the terms "transitional device" and "part of the transitional device" are to be understood synonymously, unless otherwise stated.

When the transition cover according to the invention has been slipped over the end face of the transition device, the interior of the vehicle part is correspondingly protected against external influences or environmental influences.

The transition cover according to the invention has a front side and an edge section which essentially completely surrounds the front side and protrudes from the front side with a directional component which is normal to the front side. I.e. the edge section does not have to protrude at right angles from the front side, not even straight, curved courses of the edge section are also conceivable.

The transition cover is preferably flexible or elastic to a certain degree, on the one hand to enable easy attachment and on the other hand to enable easy fastening. The design or suitability of the transition cover for putting on relates in particular to the adaptation of the transition cover to the shape and dimensions of the respective transition device, in particular of the open front side, with "open" being understood in any case to mean that the front side does not directly adjoin a vehicle part. By slipping it over, a form-fitting, detachable connection of the transition cover to the transition device can be established.

The edge section essentially serves to ensure that the transition cover is slipped over the transition device and can be fixed while the front side is used to cover the through hole.

The edge portion substantially completely surrounds the front of the transition cover. This means that there can certainly be at least one section on the front where there is no edge section, for example because there are elements on the transition device in this area that require a recess (in particular in the edge section).

In order to be able to firmly connect the transition cover to the transition device when it has been slipped over the transition device, a preferred embodiment of the invention provides that at least one tensioning means is provided, which is designed to tension the edge section circumferentially at least in sections.

Tension belts or ropes, among others, can be considered as tensioning means. Of course, however, other clamping devices are not excluded from use.

“Circumferentially at least in sections” is to be understood as meaning that the clamping means runs at least in sections along an edge of the front side and does not extend protruding from the front side or pointing in the direction. Accordingly, when the clamping means is tensioned, the edge section is pulled together circumferentially and thus pressed onto the transition device when the transition cover is placed over the end face of the transition device.

In order to be able to fasten the transition cover firmly to the transition device in a particularly simple manner, it is provided in a further preferred embodiment that the at least one tensioning means comprises at least one tensioning belt and at least one tensioning ratchet for the tensioning belt.

The combination of a ratchet strap and ratchet allows the gangway cover to be quickly and easily strapped to the gangway when in use. At the same time, this combination also makes it possible to easily loosen the tensioning straps again when the transition cover is to be removed from the transition device again.

The in particular one tension belt can be fixed at least in sections on the edge section, for example by sewing and/or gluing.

Since the transition cover should adapt as far as possible to the shape of the transition device when it is put on, in order to achieve a form-fitting cover that is as possible as possible, it is provided in a further preferred embodiment that the transition cover, in particular the edge section, is made at least in sections of an elastic and/or bellows-like material is made.

The elastic and/or bellows-like material enables the edge section to be stretched particularly well, which enables particularly simple and stable attachment to the transition device, with the transition cover also being able to better adapt to the shape of the transition device when placed over it.

To further improve the, in particular form-fitting, covering of the transition device by the transition covering, a further preferred embodiment of the invention provides that clamps and/or bellows clamps are provided for shape stabilization.

These clamps and/or bellows clamps cause the elastic and/or bellows-like material to better hold the desired shape, while at the same time ensuring the flexibility of the material used.

In particular to prevent a fire that has broken out in a vehicle part that is mounted individually from spreading uncontrollably or the resulting toxic vapors from escaping, a further embodiment of the invention provides that the transition cover is made at least in sections of an aramid fabric coated with a silicone material is made.

The aramids are aromatic polyamides that belong to the liquid crystal polymers. Aramids belong to the group of infusible, high-temperature or flame-resistant fibers. Therefore, should a fire occur in the vehicle part, an aramid transition cover prevents the transition cover itself from catching fire, which can prevent the fire from spreading further. In addition, the transitional cover keeps most of the toxic gases from escaping.

A coating of a silicone material is particularly advantageous because it increases abrasion resistance and improves resistance to chemicals and water. The silicone coating also enables a special aesthetic design by coloring the silicone coating in one or more colors.

In order to prevent the transition cover from slipping off the transition device and thus to achieve even more stable attachment to the transition device, at least one recess is provided in the edge section for receiving and at least partially passing through at least one, in particular eyelet-shaped, fixing element of the transition device.

When the transition cover is slipped over the transition device, the fixing element, in particular in the form of an eyelet, of the transition device is pushed through the recess passed through the transition cover, which prevents it from slipping off the transition device, for example during the fixing process using the tension belt and tension ratchet. A more stable fixation on the transition device is thus achieved.

Analogous to what has been said above, a system comprising at least one transition cover according to the invention and the transition device is also provided according to the invention.

According to the invention, the transition cover is designed to be slipped over the (open) end face of the transition device. With the system according to the invention it is possible to achieve an optimal matching of the transition cover according to the invention and the transition device, in particular with regard to the suitable dimensions and shape and the like. This achieves a particularly good fit or a particularly good form fit of the transition cover on the transition device, in particular on a bellows element or a frame element of the transition device. Furthermore, it is also conceivable for the transition device and the transition cover to be coordinated in terms of aesthetics or design.

Accordingly, a system is also provided according to the invention in which the at least one transition cover is arranged on at least one end face of the transition device and covers it, the at least one transition cover being detachably connected to the transition device.

The detachable connection makes it possible to use both the transition cover and the transition device multiple times. That is, if a vehicle part with attached transition device is not currently in use, the end face of the transition device can be covered with the transition cover and when using the vehicle part, the Transition cover can be removed from the transition device and temporarily stored until next use.

WAYS TO CARRY OUT THE INVENTION

In the schematic representation of 1 a transition cover 1 according to the invention and a transition device 4 are shown diagonally from the front and above. The transition cover 1 and the transition device 4 are not connected to each other. However, the transition cover 1 is intended to cover the transition device 4 on the end face.

The transition device 4 is intended to be arranged between a first vehicle part 2 and a second vehicle part 3, which are connected to one another in an articulated manner. The vehicle parts 2.3 can in particular be two wagons or wagon bodies of rail vehicles. Transition device 4 is in 1 arranged or attached to the second vehicle part 3 . In the exemplary embodiment shown, the transition device 4 is arranged entirely on the second vehicle part 3 . Alternatively, the transition device 4 can, for example, also comprise a first part 5 and a second part 6, with the first part 5 being arranged or fastened on the first vehicle part 2 and the second part 6 on the second vehicle part 3, as is shown in 5 and 6 is shown, which represent exemplary embodiments of transition devices 4 as are known from the prior art.

figure 5 shows the transition device 4, which is arranged between two articulated vehicle parts 2.3 which are connected to one another, the parts 5.6 being connected to one another. Thus, the transition device 4 can be passed by vehicle passengers in order to switch back and forth between the two vehicle parts 2.3 without having to leave the vehicle. However, the first part 5 of the transition device 4 can be separated again from the second part 6 of the transition device 4 if required, in particular if the vehicle parts 2, 3 are separated from one another.

Correspondingly, in 6 a schematic representation of the same transition device 4 as in FIG figure 5 shown, wherein the two vehicle parts 2, 3 are separated from each other. It can be seen that in this case the interior of the two vehicle parts 2, 3 and the transition device 4 are at the mercy of the environmental influences. Therefore, the end faces 7 of the transition device 4 or the first part 5 of the transition device 4 and the second part 6 of the transition device 4 can each be covered with a transition cover 1 according to the invention, so that the interior of the vehicle parts 2, 3 is protected from external influences.

The transition cover 1 according to the in 1 The embodiment shown has a front side 8 and an edge section 9 which essentially completely surrounds the front side 8 . The edge section 9 protrudes from the front side 8 with a directional component that is normal to the front side 8 . The transition cover 1 is designed in such a way that it can be slipped over the end face 7 of the transition device 4 as a type of hood or cap. This means that the transition cover 1 is adapted to the transition device 4 or to its end face(s) 7 in particular in terms of shape and dimensions. Furthermore, the transition cover 1 can have a certain dimensional stability, but at the same time be designed to be flexible in order to - at least to a certain extent - to be able to adapt to the shape of the transition device 4. Therefore, the transition cover 1, in particular the edge section 9, is made at least in sections from an elastic and bellows-like material, namely from an aramid fabric coated with a silicone material.

In very general terms, the transition device 4 has at least one end face 7, with the transition cover 1 being designed to be slipped over the transition device 4 or over the end face 7 thereof. In 2 shows how the transition cover 1 is slipped over the transition device 4 . The transition cover 1 thus completely covers a passage opening 15, which leads into the interior of the second vehicle part 3, so that it is protected from environmental influences.

In the exemplary embodiment shown, the transition cover 1 has two tensioning straps 10 in its edge section 9, which run circumferentially around the edge section 9 at least in sections and are set up to tension the edge section 9 at least in sections in order to better fasten the transition cover 1 to the transition device 4 can. The tensioning straps 10 run on two opposite sides of the edge section 9 and are guided through passages 16 so that the tensioning straps 10 cannot slide off the edge section 9 .

Furthermore, the transition cover 1 has two recesses 14 . These recesses 14 are arranged on the transition cover 4 or the edge section 9 in such a way that eyelets 13 of the transition device 4 can be passed through the recesses 14, so that a more secure and stable attachment of the transition cover 1 to the

Transition device 4 is reached. Fastening the transition cover 1 to the transition device 4 in this way prevents the transition cover 1 from slipping off the transition device 4 even better, for example. In addition, further securing means, such as a securing cord, can be passed through the eyelets 13 so that the transition cover 1 can no longer be unintentionally pulled over the eyelets 13.

In Figure 3A is a detailed view of a section through the transition cover 1 according to the section plane III-III in 1 shown, and in Figure 3B is a detailed view of a section through the transition device 4 according to the section plane III-III in 1 shown, with the arrows in 1 indicate the direction of view.

Figure 3A shows the transition cover 1, which is made of an elastic and bellows-like material. Tensioning means, namely one of the tensioning belts 10 and an associated tensioning ratchet 11, can also be seen, which are used to tension the transition cover 1 over the transition device 4. The tensioning ratchet 11 can also be used to loosen the tensioning belt 10 or the transition cover 1 again if they are the transition device 4 is to be removed.

Since sufficient dimensional stability of the transition cover 1 is to be achieved, in Figure 3A a bellows clamp 12 can also be seen.

Figure 3B shows the section through the transition device 4. The eyelet 13, with the aid of which the transition cover 1 can be fastened to the transition device 4, is clearly visible by the eyelet 13 being passed through the corresponding recess 14 in the edge section 9. Furthermore, the flexible arcuate elements of the transition device 4 are clearly visible.

4 shows a detailed view of a section through a transition cover 1 placed over the transition device 4 according to the sectional plane IV-IV in FIG 2 , where the arrows indicate the viewing direction. The representation in 4 differs from the representations of Figures 3A and 3B in that the transition cover 1 is arranged on the transition device 4, ie the transition cover 1 has been placed over the transition device 4 or over its end face 7. The transition device 4, in particular the edge section 9, is made of an elastic and bellows-like material in order to be able to enclose the transition device 4.

In 4 the tensioning belt 10 is lashed down with the tensioning ratchet 11, so that the transition cover 1 not only lies snugly on the transition device 4, but even deforms it. Is more accurate, especially in comparison with Figure 3B , recognizable that a flexible, bellows-shaped element of the transition device 4 is reversibly deformed.
