Description

The present invention relates to a drainage channel for drainage of rails, in particular tram rails, comprising a channel body with an end wall, which is associated with an inlet opening for draining a arranged in the rail head of the rail rail groove via an inlet funnel.

Such a drainage channel is already in the French patent application FR 2 765 599 A1 previously known. Such a drainage channel is used for rail drainage in tram rails, which have a rail groove in the region of its rail head. In order to ensure a safe movement of the tires of a tram in this rail groove, it must be ensured in particular during heavy rainfall that accumulating within the rail groove water is dissipated quickly and safely.

This is done via provided in the rail groove drainage openings, which are provided at certain intervals. In the area of these drainage openings of the rail grooves, the rails of drainage channels are crossed, into which the drainage openings of the rails open. For this purpose, the abovementioned, previously known solution provides for a beak-shaped inlet funnel, which is pushed from inside to the underside of the rail by means of a rail to the end wall of the drainage channel and fastened there.

In order to continue the drainage on the other side of the rail, either a drain pipe opening into the sewage system can be provided, or else the gutter line can be continued. In both cases, it is necessary that the water guided by the drainage channel can pass under the rail. For this purpose, in turn, a tunnel tube is provided, which connect the drainage channels or the drainage channel and the drainage pipe to each other below the rail from both sides. Again, according to the French specification above, it is intended first to lay the gutters on both sides and then, in a final step, to push the tunnel tube through the openings provided in the end walls of the drainage gutters under the rail from the inside of the drainage gutter.

The present invention is intended to show an alternative to push-through drainage tubes.

This is achieved by a drainage channel with the features of claim 1. Further, useful embodiments of this drainage channel can be found in the dependent claims.

According to the invention, it is also provided to essentially lay one or more drainage channels in a direction crossing the rail. As already mentioned, the inlet through the drainage opening of the rail into the gutter body usually takes place via an inlet opening of the end wall, which is assigned an inlet funnel. In contrast to the prior art, however, the solution according to the invention in the region of the end wall on a front panel, to which an inlet funnel is attached. Such a front panel is inserted into a receptacle of the end wall, which passes transversely through the end wall in the direction parallel to the rail. The inlet funnel is therefore to be fastened to the front wall from outside the inside of the channel. It is preferably provided that this is a rectangular receptacle, so that the front panel can be inserted from both sides into the receptacle. Therefore, not the end wall as such has the inlet opening, but rather the front panel, through which the water flowing in via the drainage opening of the rail passes through the inlet funnel into the channel.

An alternative to this provides that the inlet opening is provided in the end wall. For the attachment of the inlet funnel, the invention provides in this case that the inlet funnel is made in two parts, with two funnel halves are pushed towards each other in the direction parallel to the rails and meet in a central stop position where they unite to form a common inlet funnel. In this case, the inlet funnel engages under the drainage opening of the rail and connects it to the end wall in such a way that it leaves the drainage opening in the inlet funnel incoming, drainage water can enter through the end wall and the inlet opening into the gutter body. The inlet funnel is in this case preferably formed of two different materials, namely substantially of a rigid, dimensionally stable material and in the region of the rail under cross-leading edge of a soft, adapting to the position of the rail material.

In a concrete embodiment, the two funnel halves are each provided with one, preferably two or more, guide elements which are each accommodated in a rail guide flanking the inlet opening on one or both sides. Such a rail guide allows the exact positioning of the inlet funnel in front of the inlet opening of the end wall, so that the two halves of the inlet funnel connect in their stop positions to the common inlet funnel. Between the two funnel halves, a sealing lip is arranged in an advantageous embodiment, so that water entering via the inlet funnel does not seep down at the abutting edge of the two funnel halves.

In a particularly preferred embodiment, the rail guides in the region of their stop position on a latch, in which engage the guide elements of the hopper halves, as soon as they are moved to the stop position. As a result, a deflection of the funnel halves is avoided on one or both sides, so that after a single installation of the inlet funnel remains in its position.

A development of the aforementioned drainage channel points in the region of a tunnel opening provided in its end wall a projection on which a tunnel tube can be pushed from the outside. Such, pushed out from the outside tunnel tube has the advantage that a subsequent displacement of the tunnel tube, by whatever circumstances, is excluded. By the above projection on the front wall of the drainage channel, the tunnel tube can be easily positioned from the outside and continue in the other the installation either as a drain pipe or as an extended drainage channel.

In particular, it is provided to form the tunnel tube in two parts, ideally two identical parts are used. The two, preferably identical, tube halves are connected together along their longitudinal edges, wherein locking means and corresponding counter-locking means are provided in particular along these longitudinal edges. By assembling the tube halves, the locking means engage in the counter-locking means in such a way that, at least when placed on the projection of the end wall, a secure mounting of the thus assembled tunnel tube is ensured.

The tube halves may, in a concrete embodiment along a longitudinal edge having a tab which engages over a portion of the respective opposite longitudinal edge of the respective other tube half. In this overlapping portion locking means and counter-locking means can then be arranged. As a locking means or counter-locking means are particularly preferably a bead and a hierein engaging bulge to provide, which at least largely positively and / or non-positively engage with each other. However, any other locking means and counter-locking means are also usable. By using such an arrangement, although the composite tunnel tube is not stable in a disassembled state, since a lifting of the one with respect to the other part is readily possible. However, such a lifting always takes place in the direction perpendicular to the tab, wherein such evasion prevents a built-tunnel tube due to the movement in this direction perpendicular to the tab direction. Concretely, for assembly, first a tube half can be slipped from one side onto the projection, after which the other tube half is pushed over the projection from the other side. In the successive meeting of the two tube halves then snap the locking means in the counter-locking means and connect the tube halves to a common tunnel tube.

As far as a drain pipe is provided on the opposite side of the channel, so opposite the considered drainage channel, so this also has an end wall with a projection which protrudes away from the drain pipe, ie under the rail. Structurally, it is now provided that either the tunnel tube also surrounds this projection on the outside, or the tunnel tube engages in said projection. By such, one-sided spreading of the tunnel tube a divergence of the tube halves of the tunnel tube is again avoided. Conversely, to avoid slippage of the tunnel tube in the drain pipe, a stop for the tunnel tube may be provided within the projection, so that it is held in place.

As an alternative to the drainage pipe, however, a second drainage channel can be arranged on the other side of the rail be, which is constructed substantially identical to the first. In contrast to the first drainage channel, the second drainage channel can also, like the end wall of the drainage tube, have a projection which engages around the tunnel tube on the outside, instead of interfering therewith. In any case, however, in the area of the inlet opening provided at the first drainage channel, a facing or a non-penetrated end wall must be provided, since, as already explained above, a drainage opening of the rail is only present on one side. In that regard, an inlet into this second drainage channel at best by the tunnel tube, but not done by an inlet funnel or an inlet opening in the front wall.

In a concrete embodiment, the channel element can either be connected directly to an end wall, ie the end wall can be made in one piece with the channel element. Alternatively, it is possible to put the end wall directly on the gutter body, in particular to connect this with the end wall, for example with the interposition of a seal. A third possibility provides that the end wall is associated with a short, separate channel section, which can be connected as an end piece in the usual way with the drainage channel.

The invention described above is explained in more detail below with reference to an embodiment.

FIG. 10

a rail with two adjacent drainage channels, between which is composed of a two tube halves tunnel tube in a perspective view obliquely from below.

FIG. 1 shows a drainage channel in an exploded view. The drainage channel consists of a channel body 10 which is closed on both sides by end elements 11. The end elements 11 are configured such that they are designed to be drained, subsequently connected to a tramway rail. For this purpose, the end elements 11 inlet openings 15 through which collected in the tram rail surface water can enter the drainage channel. To undercut the rails additionally has the end member 11 a tunnel opening 13, which is surrounded by a projection 14. In this way, introduced into the drainage channel surface water can be introduced from the channel body 10 out into the sewage system or on the other side of the tram track continued drainage channels are derived.

FIG. 2 shows as a detail of such a drainage channel, a front element 11, which is for introducing the originating from the rail 40 ago surface water in the gutter body 10 has an inlet funnel 30. This inlet funnel is formed in two parts in the embodiment shown, namely from a first funnel half 31 and a second funnel half 32, which are moved towards each other from both sides of an inlet opening via a rail guide 34. For this purpose, the first funnel half 31 and the second funnel half 32 each have guide elements 33 which engage in the rail guide 34. With these, the funnel halves 31, 32 in the region of the side wall of the end element 11 can be inserted into the rail guide 34 and moved along its course in the direction of a stop position.

FIG. 3 shows the two funnel halves 31, 32 in their stop position. In this position, the first funnel half 31 and the second funnel half 32 complement each other to form a common inlet funnel 30, wherein a sealing element 35 in the form of a sealing lip is arranged along the abutting edge. In the stop position of the guide elements 33 within the rail guide 34, a locking is also provided, which prevents a disengagement of the funnel halves 31 and 32.

Over the thus formed inlet funnel 30, which engages under an adjacent rail 40 in the region of its rail head 41 such that the run within a rail groove 42 of the rail head 41 surface water flows through a downwardly open drainage opening 43 into the inlet funnel, the surface water from the rail 40th be introduced into the channel body 10.

FIG. 4 shows an alternative embodiment of the inlet funnel 30, which in this case with a front panel 36 is connected. Together with the front panel 36 of this feed hopper 30 is inserted into a receptacle 16 of the end wall 12. The receptacle 16 in this case represents the end wall 12 transversely by cross-rectangle, which can be completely filled by the front panel 36. In the edge region of the receptacle 16 in this case a guide rail is provided, in which the front panel 36, preferably sealing, can engage.

FIG. 5 shows the front panel 36 in its fully inserted position. A lateral insertion is possible parallel to the course of the adjacent rail 40, while the feed hopper 30 in this case remains permanently in contact with the rail head 41 in the region of the rail groove 42. In its intended position, in turn, the inlet funnel 30 engages under the drainage opening 43 within the rail groove 42, so that the surface water standing in the rail groove can enter via the drainage opening 43 and the inlet opening 15 into the drainage channel.

Here, the inlet funnel of a two-part material, namely in the region of the funnel made of a stiff, solid material and in the region of its leading edge, which comes into contact with the rail head 41, from a soft, adaptable in its shape material.

The rail 40 is underrun by a tunnel tube 20, which is connected in the region of the projection 14 with the end wall 12 of the drainage channel.

FIG. 6 shows such a tunnel tube 20, which consists of a first tube half 21 and a second tube half 22 is composed. These are two identical parts, which are easily stored in this way and can be put together arbitrarily. In that regard, each of the two tube halves 21, 22 along a longitudinal edge 23 has a bead 25 into which a flap 24 associated bulge 26 can engage. For this purpose, two identical tube halves 21, 22, rotated by 180 ° about its longitudinal axis against each other, pushed together, so that the in FIG. 7 shown configuration arises. Together, both tube halves 21, 22 form a tunnel tube 20, which configuration is inherently unstable. By a simple lifting transverse to the longitudinal axis this can be separated again.

This is prevented as in FIG. 8 is shown. The composite tunnel tube 20 is pushed onto the projection 14 of the end wall 12, which thereby prevents an upward or longitudinal deflection. This results in the tunnel tube 20 in its installed state, a stable construction, which has no disadvantages over a one-piece tunnel tube 20. In the embodiment according to FIG. 8 is used by the drainage channel opposite side an end wall 18 of a drain pipe to the other end boundary of the tunnel tube 20, so that the drainage channel the guided in her water, which enters from the rail groove 42 via the drainage opening 43 in the channel body 10, directly into the sewer can derive.

An appropriate compilation is in FIG. 9 shown, it can be seen by the lateral plan view that the end wall 18 of the drain pipe has a projection 19 which does not engage in the tunnel tube 20, but rather this embraces the outside. A removal of the tunnel tube 20 without a prior removal of the end wall 18 of the drain pipe is thus prevented.

FIG. 10 Finally, FIG. 3 shows a configuration according to which a continuation of the drainage channel beyond the rail 40 is possible. For this purpose, first the drainage channels are laid on both sides of the rails 40, such that the end elements 11 have mutually opposite projections 14. On these projections 14 then the tunnel tube 20 is then composed from both sides of the two tube halves 21, 22 by first the first tube half 21 is pushed over the projection 14 and then from the other side, the second tube half 22 is pushed over it. In this case, the bulge present in the respective tab lying over the longitudinal edge locks with the bead running along the longitudinal edge, so that after positioning the tube halves 21, 22 a separation is only possible against bending of the latching.

Thus, described above is a drainage channel for draining rails, which indicates an alternative configuration for passing the inlet funnel and the tunnel tube from the inside of the channel.
