Description

The present invention relates to a sanitary device for vehicles. The invention will be described with reference to toilets which are arranged in vehicles and in particular in trains. It should be understood, however, that the present invention is also applicable to other sanitary equipment such as showers, sinks and the like. Also, an application for other vehicles, such as trucks, aircraft, ships and the like, conceivable.

From the prior art, it has long been known that in vehicles, in particular trains, sanitary facilities, such as sanitary facilities or specific toilets, are integrated. These toilets usually have next to a toilet compact module consisting of toilet bowl, pumps for generating negative pressure, water connection, electrical connection for the control and a pipeline for discharging the fecal matter in tanks. These pipelines are usually formed in several parts in the art, so that for maintenance purposes, the toilet compact module can be removed from another pipe section. For maintenance purposes, it is often necessary to replace the actual WC compact module. Since the maintenance cycles are usually very long for sanitary sanitary facilities such as toilet bowls compared to replaceable fresh water tanks and can be replaced by trained staff sufficiently prompt, inexpensive and safe, technical Verkomplexierungen on the structure for cost and reliability reasons usually spared. At the same time, the large savings potential in the total cost calculation is misjudged, that, for example, a short and as a single item little saving reduction of maintenance time of eg trains with a variety of sanitary facilities due to the better disposition of trains, staff and maintenance resources such as maintenance places in expensive and rare maintenance halls. In addition, for safety reasons sanitary facilities, especially those for service water and even fecal matter such as toilets, although often publicly available, but should be protected unlike replaceable fresh water tanks from improper or unauthorized use. That is why they should be as difficult as possible for unauthorized persons, which at the same time makes the work of authorized service personnel difficult.

The present invention is based on the object to significantly reduce the time required for replacement of a sanitary device in a vehicle and thereby increase the quality of maintenance but at the same time to complicate the unauthorized intervention in the sanitary device. The inventive approach enhances the quality of maintenance by preventing the potential fecal leakage into the underbody of the vehicle, such as a trainset or wagon, which would require a very long repair time of several weeks. The problem here is in addition that in vehicles such as trains, for such exchanges only a very small space is available and, for example, the changing craftsman due to a lack of space and possibly also to protect against unauthorized interference can not see how the toilet compact module Drain pipe into the feces drainage pipe of the vehicle, such as a trainset or wagon.

An inventive sanitary device for vehicles has a receiving device for receiving liquids and / or solids, and a subsequent to this receiving device first pipe, which is at least temporarily and / or releasably in communication with the receiving device. Furthermore, the sanitary device has a subsequent in an installed state of the sanitary device to the first pipe second pipe and a subsequent to the second pipe tank for receiving liquids and / or solids. In this case, the first pipe and the second pipe are connected to each other and detachable from each other.

According to the invention, the sanitary device has a connection device in order to detachably connect the first pipeline and the second pipeline to one another, wherein this connecting device an insertion aid means for merging the first conduit and the second conduit and / or facilitating their assembly.

It is therefore proposed according to the invention that the assembly of the two pipes is made easier for the user by facilitating the introduction of said insertion aid even with inaccurate positioning of the first tube relative to the second tube. In particular, the Einführhilfseinrichtung and / or the connecting device should be suitable and determined to compensate for the merging of the two pipes offset, in particular a lateral offset and / or an inclination between the two pipes. In particular, the insertion aid can provide a guide with e.g. self-centering function and / or a locking function in an installed position of the first in the second tube, for example by a locking means and / or one or more closure means which is open only in the installed position and otherwise automatically have the fluid outlet from the first and / or second tube. The closure means may, for example, be configured as a fluid-tight flap in insertion assist means which is held in a closed position with a force applying means such as a spring and which is pushed by the first tube once in the installed position. Also conceivable are sealingly cooperating elastic sealing flaps, e.g. made of a rubber or a plastic or bristles, which can be pushed laterally through the first tube in the direction of insertion. By fluid is meant according to the invention liquids, suspensions of solids such as typical faeces and / or gases. The closure means has the particular advantage of reducing or avoiding the escape of malodorous and, in particular, rising gases and / or leakage of fluids despite incorrect operation.

Advantageously, at least one pipe, and more preferably both pipes, extends at least at intervals in a straight line, and more preferably at least in a region in which they are connected to one another, in a straight line. Advantageously, an introduction or supply of the first pipe section to the second pipe section in a straight-line direction. In a further advantageous embodiment, the first pipeline is formed integrally with the receptacle. However, it would also be conceivable that the first pipe is detachably arranged on the receptacle, is screwed about this. It would also be conceivable that the first pipe is welded to the receptacle.

In a further advantageous embodiment, the second pipeline is arranged integrally on the receiving tank or the receiving reservoir. However, it would also be conceivable here that the second pipeline is detachably arranged on the reservoir or also welded.

In a further preferred embodiment, the tank has an emptying opening to discharge its contents. In a further advantageous embodiment, the second pipeline extends through a wall section of the vehicle and in particular a bottom section of the vehicle. It is possible that the second pipe is firmly anchored to this bottom section.

In a further advantageous embodiment, the connecting device has a wall section whose cross-section increases from the second pipeline in the direction of the first pipeline. By this enlargement can be achieved even with an inaccurate positioning of the first pipe relative to the second pipe, that these can be more easily brought together in particular by the Einführhilfseinrichtung. Thus, this wall portion functions as the above-mentioned insertion aid for merging the pipes.

Thus, this wall section can preferably also serve as an insertion bevel in order to introduce the first pipe to the second pipe, even in the case of a lateral offset between the pipes or at a slope of one pipe relative to the other pipe. Advantageously, a cross section of the wall section widens at least by a factor of 1.1, preferably at least by a factor of 1.5.

Preferably, the wall portion and in particular that wall portion which is enlarged, in an assembled state is not in contact with the first pipe or an outer wall of this first pipe.

Advantageously, the wall section widens at most by a factor of 3, preferably at most by a factor of 2.5. It has been found that, with these enlargements of the cross-section, on the one hand, the small space requirement can be taken into account and, on the other hand, a significantly easier merging of the pipe sections is made possible.

Preferably, therefore, the connecting device has at least one insertion bevel in order to introduce and / or introduce the first pipeline into the second pipeline.

It is possible that this cross section of the connecting device widens uniformly or frustoconically. However, other extensions would also be conceivable, for example extensions of square or rectangular cross-sectional areas and the like. In the following, a frusto-conical configuration is also understood to mean frustoconical geometries in which the cross-section is not circular, but rather elliptical. Also, this extension could be done by means of circular segment or elliptical curved sections. Also in the context of the present invention about truncated pyramidal shapes are considered frusto-conical shapes and also such geometries, which have a rectangular or generally polygonal cross-section.

In a further advantageous embodiment, the connecting device has a sealing device in order to seal a connection between the first pipeline and the second pipeline in an assembled state. In this case, this sealing device is preferably formed circumferentially and in particular, for example, formed as an O-ring. In addition, this sealing device is preferably made of a flexible material, for example rubber.

In a further advantageous embodiment, the sanitary device is a toilet. However, as mentioned above, it would also be conceivable that the sanitary device is a washbasin, a sink or a shower device.

In a further advantageous embodiment, the connecting device has a circumferential and / or annular support section for supporting the sealing device. For example, a circumferential or annular seat may be provided on which the sealing device is deposited. Preferably, this support portion extends perpendicular to a longitudinal direction of the pipes.

In a further advantageous embodiment, the connecting device is formed integrally with the second pipe section. However, it would also be conceivable that the connecting device is attached to the second pipe section, for example screwed or welded to this.

In a further advantageous embodiment, the connecting device is made of a metal.

Thus, for example, a metal funnel may be provided as connecting device, which particularly preferably has at least one and particularly preferably two recesses. This metal funnel preferably serves as an insertion aid for the drainage pipe, in particular by means of a clamp, which preferably, as mentioned above, has the sealing device. In this way, a craftsman the rapid and safe insertion of the toilet compact module drain pipe in the drain pipe of the vehicle to the sewage tank, such as the trainset, allows.

In contrast to configurations known from the prior art, the operating personnel in this case no longer have to search for the drainage pipe of the vehicle during assembly, but can to a certain extent "thread" the first pipe and save significant time when replacing the WC compact module. In addition, the use of the funnel preferably prevents "tilting" of the WC compact module outflow pipe to the vehicle outflow pipe and thus prevents the outflow into the subfloor.

In a further advantageous embodiment, the wall section has at least one recess. This means that the wall section is in particular not continuous along its entire cross section or its entire height, but has at least one recess.

At least one positioning device is advantageously formed in the wall section in order to fix and / or fix a rotational position of the first tube relative to the second tube. This may be, for example, guide rails, which are formed in the wall portion. Advantageously, the connecting device has a wall thickness which is between 0.2 cm and 2 cm.

In a further advantageous embodiment, the wall section has at least two recesses. Advantageously, these two recesses are separated from each other by a projection. This projection may in turn extend in such a way that a section between this projection and an opposite wall section of the connection device increases in particular continuously from the first pipeline to the second pipeline.

Preferably, at least one of these recesses extends and preferably both recesses extend to an upper edge of the wall portion, i. a extending in the direction of the first pipe edge of the Wandungsabschnitts. Preferably, therefore, at least one recess towards the top, or in the direction of the first pipe open. However, it would also be conceivable that at least one of the recesses has an upper boundary edge, which in turn facilitates the insertion of the first pipeline.

In a further advantageous embodiment, the wall portion has a first, in particular frustoconical and in particular completely circumferential base portion and a second adjoining the first wall portion second wall portion, which is preferably formed in sections frusto-conical and in which preferably at least one recess is arranged on. This means that at least the first wall portion extends circumferentially, whereby an assembly of the pipes is facilitated. The second wall section has in particular at least one recess, preferably at least two recesses, which in turn may be in an assembled state in the region of this recess further elements, such as valve elements, which must be accessible to the user in a mounted state of the sanitary device.

If one were to refrain from the recess, the entire connecting device preferably has a frustoconical shape. This means that the recesses connect to the wall section and preferably continue in the form of a truncated cone.

As mentioned above, the connecting device may be circular. However, it would also be possible that the connecting device is elliptical or formed in other geometric shapes, so as to be better adapted to the installation situation.

It would also be possible for the connecting device to have a receiving section for the preferably form-fitting reception of the first pipeline. In this way, a reliable seal between the first pipe and the second pipe can be achieved. In addition, this receiving portion for receiving the pipe may also have a different shape from a circular shape, in order to achieve in this way that the two pipes can be joined together only in a precise rotational position.

In a further advantageous embodiment, the device has a latching mechanism by means of which the two tubes can lock. Coupling devices would also be conceivable in order to connect the first pipeline to a connecting device and / or the second pipeline, such as bayonet-type connections or the like.

In addition, it would also be conceivable that it is locking elements, which cause the first pipe can engage in the connecting device.

In a further advantageous embodiment, the device has a signal output device which indicates to a user a final target position of the second pipeline with respect to the first pipeline. For example, it is possible to provide an element which, when the first pipeline is pushed together to the second pipeline, emits an acoustic signal, such as a clicking sound, so that the user recognizes that the first pipeline is now properly attached to the second pipeline. For this purpose, a mechanically contactable element can be arranged, for example, in a wall region of the connecting device, which emits a corresponding acoustic signal when moving through the first pipeline.

Overall, a fast and safe introduction of a toilet drain pipe in a fecal pipe, such as the trainset, made possible by the invention. On the other hand, due to the not too overflowing funnel shape of the connecting device, the confinement of the space which is usually available in such vehicles is also taken into account. Preferably, as mentioned above, at least one recess and preferably two recesses in the connecting device and in particular the frusto-conical wall portion are provided. In this way, the WC compact module drainpipe, that is, the first pipe, incl. Fasteners are optimally inserted into the peripheral wall or in the connecting device.

The present invention is further directed to a connecting device for connecting pipelines, in particular for sanitary facilities in vehicles, with an insertion aid to merge the pipes to be connected. According to the invention, the connecting device has at least one wall section whose cross-section increases from one of the pipes to be connected in the direction of the other of the pipes to be connected. Preferably, the connecting device is configured in the manner described above. In a further preferred embodiment, the connecting device (apart from a possible sealing device) is integrally formed. Preferably, at least a portion of this connecting device is used for positive and / or non-positive reception of at least one pipeline.

The present invention is further directed to a vehicle, and more particularly to a rail vehicle having a sanitary device of the type described above.

Further advantages and embodiments will become apparent from the accompanying drawings.

three embodiments of a connecting device.

Fig. 1 shows a schematic representation of a sanitary device according to the invention 1. In this case, the reference numeral 2 refers to a receiving device, such as a toilet bowl, which is known manner for receiving the feces. At this receiving device is followed by a first pipe 4 for discharging the fecal matter. The reference numeral 6 denotes a second pipe, which can be brought via a connecting device 10 with the first pipe 4 in connection. The reference numeral 20 denotes a bottom through which the second pipe 6 extends. The reference numeral 8 refers to a tank or a reservoir for receiving the feces. For assembly, the first pipe 4 is connected via the connecting device 10 with the second pipe 6. One recognizes already in Fig. 1 in that a funnel-shaped arrangement is provided on the connecting device 10, which makes it possible to align the two pipes 4 and 6 with respect to one another when the receiving device 2 is lowered.

Fig. 2a shows a schematic representation of a connecting device 10, by means of which the two pipes can be connected. It is possible that this connecting device 10 is integrally connected to the pipe 6. However, it is also possible that the connecting device 10 is also attached to the pipe 6, for example screwed and plugged or the like.

The connecting device here has a cylindrical portion 24 which can be attached to the pipeline 6, for example. This cylindrical portion completely surrounds the first pipeline 4 in its circumferential direction in an assembled state. Preferably, this cylindrical portion contacts the first pipe in the assembled state in full. Thus, preferably, the cylindrical portion perceives the function of a cuff.

At this cylindrical portion 24 is followed by a conical portion denoted by 12 in its entirety. This conical section 12 in turn has a first conical section 12a, which is continuous in a circumferential direction and therefore has no gaps, openings or the like. At this first portion 12a, a second portion 12b follows, which is also conical here, but has two openings 16a, 16b, between which a web or a projection 18 is arranged. The boundary edges of the recesses 16a, 16b are curved here executed. The conical section takes, as stated above, the function of the insertion aid true. The projection 18 also assumes the function of an insertion bevel with a corresponding lateral offset.

The two recesses preferably have a width (in the circumferential direction of the connecting device 10) which is smaller than a cross section of the pipeline to be introduced. In particular, a maximum width is smaller than a cross section of the pipe 4 to be introduced. In this way it can be prevented that the pipe 4 jammed or wedged during insertion into the recess. For assembly, it is therefore sufficient if an end portion of the first pipe is within the cross section of the Wandungsabschnitts 12. When approaching the first pipe is guided in the direction of the first portion 12 a and finally enters the cylindrical portion 24th

In an assembled condition, the first conduit 4 is within the wall 12. The recesses 16a, 16b serve to accommodate elements such as valve sections. These recesses serve to allow a proper centering of the two pipes with respect to each other even in the smallest space. Advantageously, the two recesses 16a, 16b are symmetrical with respect to a predetermined median plane. The dashed line indicates the transition between the two wall sections 12a and 12b.

Fig. 2b shows a further illustration of the connecting device from a different perspective. Also in this illustration, the two recesses 16a, 16b are recognizable again.

Fig. 3 shows a further embodiment of the connecting element 10. It can be seen here again the wall portion 12, but here the recesses are not shown. The reference numeral 30 denotes a signal output device which outputs a preferably audible perceptible signal when the first (not shown here) pipeline is arranged correctly in the connecting element 10. This may be, for example, an element which gives a cracking noise or the like upon insertion of the pipe 4.

Fig. 4 shows a plan view here from above on the connecting device. Here, again, the first continuous wall section 12a is shown, and in turn the second wall section 12b, which, however, has the two recesses 16a, 16b.

The reference numeral 14 denotes a sealing device which serves to establish a tight connection between the two pipe sections. During assembly, the first pipeline is pressed firmly from above to the sealing device. The sealing device in turn rests on a valve seat (not shown). In turn, this valve seat is in each case tightly connected to the second pipeline (not shown). Reference numeral 24 denotes the cylindrical flange portion into which the first pipe 4 is inserted. It would be possible that this section 24 only has a slightly larger cross-section than the pipe to be introduced therein. In this way, a tight fit and also a seal of the two pipes can be achieved with respect to each other. It would also be possible for a tensioning element to be provided in the region of this cylindrical portion 24 with which the two pipes 4 and 6 can be fastened to one another.

The FIGS. 5a-5c show (not necessarily) three possible embodiments of the pipeline more precisely an end portion 4a of the pipeline, which is arranged in the connecting device. At the in FIG. 5a shown illustration, both the pipe 4 and the connecting device 10 has a circular cross-section. At the in Fig. 5b In the embodiment shown, the cross sections are each elliptical and in the in Fig. 5c As shown, they are composed of a circular section and an elliptical section. In the in the Fig. 5b, c As shown embodiments, the pipeline can be supplied only in a very specific rotational position.

In an installed state, the two pipes preferably extend in a substantially vertical direction.
