Description

The invention relates to a frame for a drainage channel or for a shaft for supporting a gutter or manhole cover, with a in the installation situation at least substantially perpendicular, in imaginary extension of an outer surface of the side wall of the gutter or manhole cover arranged Zargenrand, of which a Upper edge of the respective side wall of the gutter or manhole cover cross, at least substantially horizontal support surface in the installation situation for the gutter or manhole cover and arranged this bearing surface relative to the upper edge of the Zargenrandes at least substantially offset by the height of the respective gutter or manhole cover down is, wherein this support surface merges into a downwardly angled side skirt, which is arranged in the installation situation, at least substantially in imaginary extension of the inner surface of the side wall of the gutter or manhole cover, where is provided at the frame edge with a projecting in the direction of the gutter or manhole cover snap fastening, which is in the installed position with the gutter or manhole cover engages such that the gutter or manhole cover is reversibly secured in the intended installation situation.

Such a device for locking gutter covers in frames is from the EP 0 908 568 A1 previously known. In this prior art device, the frame is provided on its side facing the gutter cover with a protruding in the direction of the gutter cover tongue. In this case, this tongue is connected to one of its perpendicular to the longitudinal direction of the frame extending sides with the frame. Furthermore, the projecting in the direction of the gutter cover tongue is open in all other directions, ie on the side opposite the mounting side, as well as up and down. The gutter covers are in turn provided according to the previously known solution with recesses into which engages the projecting tongue in the installed state. As a result, the gutter cover is reversibly secured or fixed in the installation situation in their relative position to the frame.

In practice, however, has proven that the spring tongues tire with increasing use, in which case to maintain the attachment function is only possible to replace the frame as a whole.

Incidentally, the previously known frames are produced by means of complex presses, so that the production is associated with considerable tooling costs. After a separate tool is required for each frame, the previously known solution, at least not economically useful in conjunction with frames that are needed in small numbers, are used.

Finally, the previously known solution against the background that the tongue in order to fulfill their security function, must have a certain width, in turn, a minimum height of the frame ahead, but not in all applications is useful or desirable. In that regard, the scope of the previously known solution is limited.

Furthermore, from the DE 94 12 105 U1 also previously known a reversible attachment for a gutter cover in a frame. In this solution, the gutter cover with a in the installed position below the gutter cover arranged cross bar provided, which is accordingly arranged in the installed position within the drainage channel, wherein the drainage channel is provided with receiving chambers in the side walls, in which the cross bar can be pivoted so that it engages in this, wherein the cross bar is provided with a screw connection and can be determined by tightening the screw in this position securing the gutter cover in the installed position. Again, it is a releasable attachment of the gutter cover in the frame of a drainage channel, which also has the problem that the screw dirty with increasing use, is clogged and possibly no longer solvable by the increasingly with increasing use caked foreign matter ,

Drainage channels or shafts are often provided to protect their upper edges with Zargen- or edge protection devices, which serve in addition to record grating and secure in its intended position. This is intended to achieve a permanent usability of the drainage devices in conjunction with the stabilization of the mentioned upper edges. With regard to securing the cover grids is also to be noted that they should be both easy to assemble and disassemble, preferably without the need for additional tool is required. The dismantling of the grating is required because from time to time the drainage channels or shafts need to be cleaned about by flushing or other foreign matter must be removed. At the same time, the backup of the grating should be tamper-proof, so be prevented that such covers are opened without authorization.

In connection with the attachment of the covering grates there is the additional problem that the compounds become increasingly polluted during prolonged use and accordingly are increasingly difficult to detach.

The invention is therefore based on the object to provide a frame that allows a secure attachment of the grids of drainage channels or shafts on the one hand, on the other hand, even after a long period of time is still easy to solve and otherwise can be easily mounted on site ,

This object is achieved by a frame according to claim 1. Advantageous embodiments of this frame can be found in the dependent claims 2 to 9.

According to claim 1, the frame according to the invention is also provided with a snap fastening for a gutter or manhole cover. In contrast to all previously known from the prior art solutions, however, the snap fastening by means of a releasably inserted into the frame spring clip can be realized. This means that the snap fastener can be replaced if necessary, especially if this is possibly no longer permissible in their function due to material fatigue.

The frame consists of an arranged in the installation situation in an imaginary extension of the outer surface of the side wall of the gutter or manhole cover Zargenrand from which extends an anterontal support surface, which is approximately offset by the height of a gutter or manhole cover down. For this purpose, the Zargenrand is provided in the region of its upper edge with a Umbug to which a parallel to the Zargenrand arranged, this spaced inner skirt connects, which then merges by means of another Umbugs in the subsequent, at least substantially horizontally arranged bearing surface of the frame. The horizontally arranged in the installation situation bearing surface engages over the upper edge of the side wall of a gutter or manhole cover and goes by means of a Umbugs in a mounting situation substantially vertically arranged side skirt, which is arranged in an imaginary extension of the inner surface of the side wall of the gutter or manhole cover , This side skirt is provided with spaced-apart recesses. In this known per se Zargenelement can then be inserted according to the inventive solution of the bearing surface facing away from the underside formed as an angle spring clip.

The extent easy to use spring clip can be pre-assembled in a simple manner. Incidentally, can be dispensed with expensive tools for production.

The spring clip essentially consists of a gutter arranged vertically in the installation situation and a drainage surface angled away from it in an at least substantially right angle. In this case, the in the installation situation substantially vertically arranged intermediate web of the spring clips is inserted into the space between the frame edge and the inner skirt. In addition, a projecting in the installation situation in the direction of the inner surface of the side wall of the gutter or manhole cover holding web is integrally formed on this gutter. If this holding web reaches the region of a recess of the inner skirt, then this can protrude through this recess in the direction of the inner surface of the side wall of the gutter or manhole cover and accordingly the spring clip in the installation situation are locked as intended. In this position, the gutter is inserted into the area between the frame edge and the inner skirt, wherein the angled run-off surface of the spring clip engages under this surface, the support surface of the frame. In a further step not of interest here, the actual gutter or shaft body is then formed on the frame element in such a way that the upper edge of the gutter or shaft body is intentionally overlapped by the frame, thus the outer surface of the frame edge is flush with the outer surface of the side wall of the gutter - Or shaft body and also closes the side skirt of the frame flush with the inner surface of the side wall of the gutter or shaft body, wherein in the areas in which the spring clips are arranged, the upper edge of the side wall of the gutter or Manhole cover is covered by the drainage surface of the spring clip. As a result, the frame is usually connected at the factory to the gutter body in a simple manner.

In a further embodiment, the retaining web of the spring clip is angled twice such that a jump connects to a first projection, followed by a further, downwardly open second projection in the direction of the inner surface of the side wall of the gutter or manhole cover connects. In this case, the first projection is a cover for the second, downwardly opened projection, so that no dirt can penetrate into this area, thus the downwardly opened projection with a fastener, such as a fastening web or a fastening tab, a gutter or manhole cover are connected can, this compound is secured by the first projection against penetrating dirt, so can not enforce gradually by penetrating dirt. This has the advantage that the connection can be easily solved even after prolonged use, so if necessary, the covers can be removed.

In this case, the spring clip in an advantageous embodiment as a thin stainless steel element, that is stainless, manufactured.

In addition, according to claim 6 in the region of the transition from the inner skirt to the support surface below the recesses provided a drain opening so that in this area penetrating dirt can not accumulate in this area, but rather is flushed through this drain opening with the penetrating surface water and in the Area passes below the bearing surface of the frame.

In another advantageous development of this solution, in turn, at the level of the recesses, that is again below the holding web extending through these recesses, realized in the region of the means of a third Umbugs Transition from the support surface to the inner surface of the side wall of the gutter or manhole cover facing side skirt provided a flushing opening, so that through the drain opening in this area penetrated dirt, which then rests on the drainage surface of the spring clip, in conjunction with in this area penetrating surface water through this Rinsing opening is discharged into the channel of the drainage channel or the drainage shaft. The drain opening in the region of the support surface realized in conjunction with the flushing opening in the side skirt an automatic cleaning in the connecting region between the frame and a gutter or manhole cover.

According to claim 7 extending in the longitudinal direction of the channel or the shaft bearing surface of the frame is provided in each case at the level of the recesses with a further insertion opening. In conjunction with this insertion opening a cover knobs can be used, with this opening is closed. With the cover nubs open, an additional flushing of the drainage surface through this opening can be carried out in this area.

In a further embodiment, the side skirts of the frame are provided with spaced, projecting in the direction of the adjacent gutter or manhole cover locking nubs that fix a designated in the frame gutter or manhole cover in their respective relative position in the frame intended. The cover can then be solved without additional tools by overcoming the mediated by the locking knobs detent resistance from the frame. The locking knobs thus serve to releasably fix the gutter or manhole cover in the frame.

The frame according to the invention is produced particularly advantageously inexpensively in the roll process.

The invention will be explained in more detail with reference to an embodiment shown only schematically in the drawing.

Fig. 1 shows a frame 1 in a side view, with a vertical in the installation situation Zargenrand 2 with a horizontally arranged in the installation situation support surface 3 extending from the frame edge 2 relative to the upper edge 4 of the Zargenrandes 2 to about the height of a gutter or manhole cover, which is not shown in the drawing, offset downwards forterstreckt. In this case, the frame edge 2 as shown in FIG Fig. 4 provided with an upper-side first Umbug 5, to which on the inside of a drainage channel or a shaft side facing a Zargenrand 2 parallel inner skirt 6 connects. This inner skirt 6 is provided with spaced-apart recesses 7.

In this case, the support surface 3 of the frame 1 as shown in FIG Fig. 2 each provided at the height of the recesses 7 with through openings 10.

As shown in Fig. 4 the inner apron 6 via a second fold 11 in the support surface 3 via. The support surface 3, in turn, in the region of the side edge facing the inside of the channel or the shaft, passes over a third fold 12 into a side skirt 13 which is angled downwards relative to the support surface 3. Thus, the Zargenrand 2, the inner skirt 6, the support surface 3 and the side skirt 13, which are each connected by one of the umbugs 5, 11, 12, a first part of the frame 1. In this first part of the frame 1 can then from below the support surface 3, a spring clip 14 designed as an angle element is inserted, wherein this spring clip 14 comprises a drainage surface 15 arranged below the support surface 3 in the installation situation and an intermediate web 16 angled for this purpose. In this case, a projecting in the direction of the inside of the groove or the shaft holding web 17 is integrally formed on the intermediate web 16.

This angled retaining web 17 is first, when the intermediate web 16 is inserted into the region between the frame edge 2 and the inner skirt 6, pressed and jumps when it enters the region of one of the recesses 7, in the direction of the inside of the channel or the shaft and passes through the respective recess 7, so that the spring clip 14 is connected to the above-described first frame part such that the drainage surface 15 engages under the support surface 3 at a distance.

According to this Fig. 4 such preassembled frame 1 is then formed in a corresponding shape a channel body 20 such that the frame edge 2 in imaginary extension of the outer surface of the side wall 21 and the side skirt 13 in an imaginary extension of the inner surface of the side wall 22 of the channel body 20 according to Fig. 3 are arranged.

As shown in Fig. 4 the spring clip 14 is inserted into the first frame part such that the intermediate web 16 up to the stop formed by the fold 5 in the area between the frame edge 2 and the inner skirt 6 is included. In this case, the opposite of the intermediate web 16 angled run-off surface 15 engages the support surface 3 at a defined distance. The integrally formed on the spring clip 14, angled retaining web 17 passes through in this position, a corresponding recess 7. In this case, the holding web 17 as shown in FIG Fig. 3 two angled, namely such that on a first projection 23 is a return 24 in the direction of the inner skirt 6, to which a second, downwardly opened projection 25 connects. Accordingly, the first projection 23 overlaps the downwardly opened second projection 25 such that no dirt can penetrate into the region between the holding web 17 and the inner skirt 6 or the recess 7 arranged in this region. After the retaining web 17 is used to be connected to an engaging in the formed by the retaining web 17 undercut fastener of a gutter or manhole cover, thus this mounting area is kept free from the upper side penetrating dirt elements. This ensures that the attachment can be loosened in a simple manner even after a prolonged period of use, without the need for costly removal of encrusted or caked dirt elements in this connection.

Like also out Fig. 3 can be seen, the region of the second Umbugs 11 is provided with a drain opening 26, as shown in the FIGS. 3 and 4 is extended in the region of the support surface 3. By means of this drainage opening 26, contaminants that have occurred in this area, for example, can be discharged downwards by means of the surface water entering through the bearing surface 3, in order then to reach the drainage surface 15 below the bearing surface 3. About the drainage surface 15 then passes this occurred surface water with entrainment of any existing contaminants in the direction of a scavenging port 27 formed as opening of the side skirt 13 and in the course in the channel of the channel body 20th

As a result, in the region of the attachment of the gutter or manhole cover entering contaminants are first discharged through a drain opening 26 on the support surface 3 under cross-drainage surface 15 and then further discharged through the flushing hole 27 into the gutter body 20 and thus a total. The frame 1 according to the invention thus realizes a self-cleaning frame 1, in particular in the fastening region of the gutter or manhole covers.
