EP2904161B1 - Slot drain - Google Patents

Description

The invention relates to a slot channel for surface drainage and a connection device according to the preamble of claim 1 and 7.

Such slot grooves are for example from the EP 1 499 779 B1 or the DE 83 34 717 U1 are known and serve over long distances to provide drainage for surface water, the drain is ensured by a usually only a few inches wide slot in the ground. This slot is formed by an upper part of a channel body, wherein the channel body itself usually has a relatively large cross-section. A similar construction is also in the JP 2010 090655 A and the EP 1520942 A1 described.

When laying such slot grooves, it is very important to an exact alignment of the slot-shaped inflow opening of gutter element to gutter element, since just with such narrow inlet openings, an offset visually very disturbing. In addition to the optics, however, there is a further problem of an offset in that this displacement is passed on during paving. The effort that is spent in laying such grooves is therefore quite high.

The WO 2004/059201 A1 describes a laying method for a sewer pipe, which has juxtaposed partial pipe shells, which are connected via locking pins and detent holes. The tubes can be pulled with a drilling device in an earth environment.

To simplify the laying describes the GB 2 448 664 A a way as mutually abutting slot grooves can be laid by means of additional measures so that the inlet openings are aligned from one groove to the other. The US 2007/0099782 A1 describes for this purpose a fixing rib, which is used to connect two slot grooves. The EP 2 372 021 A1 describes that two elements of a run-off can be connected by their cover piece, wherein a cover piece has an elevated profile, to which another Cover piece can be attached. However, it has been shown that these known measures are expensive.

The document GB2448664 is considered to be the closest prior art. This document corresponds to the preamble of claims 1 and 7.

The invention is based on the object to show a slot channel and a connecting device for connecting two adjacent channel bodies of slot channels to the effect that with a simple deployment of the slot channels a highly accurate result is achieved.

This object is achieved by a slot channel according to claim 1 and a connecting device according to claim 7.

In particular, this object is achieved by a slot channel for surface drainage, comprising a channel body with an upper part, which has a slot-shaped inflow opening and a connecting device for the flush connection of two adjacent channel bodies at their end faces, that the connecting device in the inlet opening of two adjacent tops, bridging these can be used. The fact that the connecting device directly into the inlet opening - and in particular or preferably flush with the upper edge of the upper part, which forms the inflow -, ensures that the inflow openings of adjacent grooves inevitably run in alignment, even if the gutter body is not exactly aligned. The connecting device in this case has a base body which can be fastened in the upper part of a channel body and a bridge body movably attached thereto so that the bridge body can be moved into an installed position from an open position in which the two upper parts to be joined are mutually movable, in particular tiltable about their longitudinal direction in which the two tops are aligned. This ensures that the connecting device is captively connected to a slot groove or its upper part and by simply moving the closed position can be achieved, in which two adjacent grooves are interconnected.

Preferably, the connecting device in the inserted state, when connecting two adjoining slot channels, in both inflow openings equally deep and symmetrical to the end faces, preferably arranged flush with the surface (to the upper end of the inflow opening). This achieves maximum stability.

Preferably, the bridge body is connected to the base body via a pivot joint. This type of connection is particularly easy to produce.

Such a connection device can be produced in a particularly simple manner if the bridge body is formed integrally with the base body and (if appropriate) the pivot joint, preferably as a plastic (injection-molded) part. Furthermore, such a construction is particularly inexpensive.

It is also possible that the connecting device in several parts, eg with a separate pivot joint of a fabric strip or a swivel joint made of a different plastic, is formed. It is also conceivable that the pivot joint is made of metal. This is useful if particularly high mechanical stresses on the pivot joint are to be expected.

Here, the connecting device in an open position completely in the inlet opening of an upper part is receivable. This means that the connecting device can be handled together with the gutter body and its upper part without the risk of losing, damaging or injuring the connecting device.

The connecting device preferably has a top visible in the inserted state from above, which can be used for marking by a preferably phosphorescent or luminous coloring. This gives the connection device a further function which improves the general usability of the overall arrangement. Simple orientation aids or warnings (for example on the edge of a pedestal or a staircase) can be attached in this way.

Likewise essential to the invention is a connecting device for connecting two adjoining channel bodies of slot channels, each having an upper part with a slot-shaped inflow, considers, when the connecting device - as described above - is formed. This connection device can be used in any type of slot groove to keep the inlet openings during assembly in alignment.

In the following description, the same reference numerals are used for the same and the same parts.

As in Fig. 1 A slot channel, as known per se, comprises a channel body 1, which is installed in a concrete base 2 in the installed state. On the gutter body, a top 10 is fixedly mounted, which comprises two (parallel) side walls which form an inflow opening 11 between each other through which surface water flow into the interior of the gutter body 1 and can be removed there.

The gutter body 1 with its upper part 10 is filled with a structure 3, on which a paving bed 4 and thereon a plaster 5 are mounted so that the upper part 10 and the inflow opening 11 are flush with respect to the surface of the patch 5 or sunk.

In the following description of a connecting device 20, which is used for connecting two upper parts 10, 10 '(and thus the entire slot groove) is summarily on the Fig. 1-17 referenced, in which various aspects of the connector with the upper part 10, 10 'are shown.

The connecting device 20 comprises a base body 21, on which a bridge body 22 is pivotally attached via a pivot joint 23, which is formed as a film hinge (see Fig. 7 ).

The bridge body 22 has a top part 24 (when it is closed upwards), which has an upper part 24 which is colored by a corresponding coloring, e.g. may have a marking effect accomplished with a phosphorescent or otherwise luminous material.

It is easy to imagine that in a whole gutter, at the usual intervals (eg 1 meter) markings as in Fig. 4 shown, such a "leadership effect" is well achievable.

The bridge body 22 has side cheeks 25, 25 ', the base body 21 has side cheeks 26, 26'. Both the base body 21 and the bridge body 22 are provided with fastening hooks 28 which (in the inserted state of the connecting device 20) have steep flanks at their upper end and flanks sloping gently towards their lower end.

In the base body 21, a transverse continuous fixing slot 29 is further provided, while the bridge body 22 has a wider recess 30. At this point it should be noted that Fig. 7 shows the position of the connector 20 in which it is molded or taken out of the injection molding machine.

The upper part 10, 10 'has (as in particular in the Fig. 2, 3 and 4 shown) sidebars 12, 12 ', which have inwardly bent fold edges 13, 13', between which the inflow opening 11 is formed. The side strips 12, 12 'are at the ends of each channel (possibly also still partially in middle areas) by separating webs (14, 14') held at a distance from each other but also connected to each other.

In the factory now the connecting device is partially assembled. For this purpose, a base body 21 is inserted into each upper part 10 or 10 'in such a way that the base body with the fixing slot 29 sits on the separating web 14, 14'. The fastening hooks 28 snap here behind the lower edges of the seam edges 13, 13 ', whereby now the base body 21 in the inflow opening 11 between the side strips 12, 12' is fixed. In this state, the bridge body 22 is in the in Fig. 3 shown position, that is essentially completely together with the base body in the inflow opening between the side strips 12, 12 'added.

Now, if two channel body 1 with their tops 10, 10 'are placed against each other, the bridge body 22 is folded (by about 160 to 170 degrees), so that in the 4, 5 and 6 shown position is reached. In this position, the fastening hooks 28 of the bridge body 22 snap behind the fold edges 13, 13 'of the side strips 12, 12', whereby now the bridge body 22 as well as the base body 21 can be levered out of the inflow opening 11 only with increased force. Furthermore, it should be noted here that the bridge body 22 the base body 21 so tightly encloses (see Fig. 6 ) that one in Essentially positive connection is formed and so a "blocks" is formed, which is substantially symmetrical (see Fig. 4 ) is seated between the upper parts 10, 10 'or sidebars 12, 12' of adjoining grooves. The upper part 24 is in this case offset slightly downwards relative to the upper edges of the upper part 10, 10 'or the inflow opening 11, so that there is no danger of a load on the connecting device 20 when passing or driving over.

From the above it is apparent that for the most essential parts of the present invention, a special design of the gutter body with its upper part is not necessary. The connecting device 20 can also be used together with slot grooves of a different type, with possibly a different connection of the base body 11 (and of the bridge body 22) with the upper part 10, 10 'is possible.
