Description

Cover for a drainage channel

The present invention relates to a cover for a drainage channel according to the preamble of claim 1 or claim 6.

Such covers are known from EP 433 410 Bl. To secure the grating serve two made of spring steel security parts, which are plugged onto the cover. This structure is relatively complicated and expensive.

From EP 640 728 Al a cover with a cover grate is known, which has two hooks on one of its two longitudinal sides, which engage in a recess in the channel body after assembly. For attaching a plurality of cover grates they are successively attached to one end of the gutter body and pushed to the other end. This embodiment of the cover has the disadvantage that the last cover grille by an additional part in the form of a

Securing bracket must be secured before lifting out.

From US 5,181,793 a cover with a cover grate is known, which has two opposite hooks, each after mounting in an open-topped groove in

Grab gutter body. In the grooves, however, material may accumulate over time in the form of dust, leaves, impurities, etc. If a cover grille is to be replaced, the grooves must be thoroughly cleaned beforehand.

It is also known to produce the support frame for the cover grate, for example, by casting in one-piece mold. This makes the production relatively complex, on the one hand, the space in the casting boxes is not optimally utilized and On the other hand, for any desired width complete support frame must be made.

Based on this prior art, a first object of the present invention is to provide a cover which allows a simple and secure attachment of a cover grating to a support frame, even after prolonged use. A second task is to make the production of the cover rational.

A cover which achieves the first object is given in claim 1. A cover, which solves the second object is specified in claim 6. The other claims indicate preferred embodiments as well as a drainage channel with a cover.

According to claim 1 resilient retaining elements are formed by the provision of through openings on the support frame. As a result, a simple and secure attachment of the cover grille is ensured, whereby accumulation of material is prevented.

According to claim 6, the support frame comprises two longitudinal parts and two transverse parts, whereby a more rational production is ensured. Thus, e.g. Support frames are made with different width in a simple manner by cross members are provided with different lengths.

The invention will be described below with reference to preferred

Fig. 14 the cover grid according to Fig. 11 in a side view.

As shown in FIG. 1, the cover comprises a support in the form of a support frame 20, which has on its two longitudinal sides through openings 21a, 21b in the form of slots, and a cover grid 10 mounted on the support frame 20, which at its two longitudinal sides one Hook IIa, IIb has. By providing the openings 21a, 21b holding elements in the form of resilient webs 22a, 22b are formed, under each of which a hook

IIa, IIb attacks, whereby the cover grate 10 is secured against lifting. The hooks IIa, IIb and holding elements 22a, 22b form a detachable connection between cover grate 10 and support frame 20, wherein the cover grate 10 without screws or similar fastening means on the support frame 20 can be fastened.

As is apparent from FIGS. 2 to 5, the cover grate 10 has elevations 12 on its upper side and reinforcing ribs 13, 13 'on its underside, between which inlet openings 14 for introducing the water into the drainage channel are arranged. As particularly shown in FIGS. 3 and 4, the two reinforcing ribs 13 ', which are located in the center of the Abdeckrostes 10, each end connected to each other. At the respective junction an outwardly facing projection is formed, which forms the hooks IIa and IIb.

The material of the cover grate 10 is chosen so that the hooks IIa, IIb are rigid. The cover grate 10 is together integrally formed with the hook IIa, IIb and made of metal, such as cast iron, or plastic.

As further Fig. 1 shows, the support frame 20 is formed in several parts. It comprises two longitudinal parts 25a, 25b whose ends are connected by two transverse parts 26a, 26b. As can be seen in particular from FIG. 2, the longitudinal parts 25a, 25b each comprise a projecting region which has a support surface 27a or 27b for the cover grating 10 and through which the opening 21a or 21b extends. The position of the support surface 27a, 27b is chosen so that the top of the support frame 20 and the top of the Abdeckrostes 10 come to lie substantially at the same height.

Various views of the support frame 20 are shown in Figs. 6-8. The support frame 20 has a substantially rectangular floor plan. The longitudinal parts 25a and 25b are formed substantially the same. Also, the cross members 26a and 26b are substantially the same, but they are rotated 180 degrees to each other with the longitudinal parts 25a and 25b. In the following, the longitudinal part 25a and its connection with the transverse parts 26a, 26b will be described in more detail. The description applies analogously to the longitudinal part 25b and its connection to the transverse parts 26a, 26b.

As particularly shown in FIG. 6, the slot 21a and thus the web 22a extend in the direction of extension of the longitudinal part 25a. If a force acts laterally on the web 22a, as indicated by the arrow 28 in FIG. 6, the web 22a is displaced so that the width of the slot 21a is reduced and the distance between the two webs 22a and 22b is increased. Since the slit 21a forms an opening which passes through the longitudinal part 25a is formed, material, which is located in the water to be discharged, through the slot 21 a through. Any accumulation of the material is prevented and ensures the resilient behavior of the web 22a even after prolonged use of the cover.

The ends of the longitudinal part 25a have protruding connecting elements 29a, 29b, which are arranged below the support surface 27a and each engage in a recess in the form of a pocket 30a, 30b, which in the

Cross member 26a and 26b is formed. The connecting elements 29a, 29b are dovetail-shaped. In the plan view according to FIG. 6, the connecting elements 29a, 29b widen outwards and in the side view according to FIG. 7 they narrow upwards.

A respective pocket 30a, 30b of the transverse part 26a or 26b is undercut, so that it widens outwards in the plan view according to FIG. Seen in the side view according to FIG. 8, it narrows from above and from below towards its center. A perspective view of the connection between the longitudinal part 25a and the transverse parts 26a and 26b can be seen in the bottom left and top left in FIG.

The embodiment of the connecting elements 29a, 29b and the recesses 3 Oa, 30b shown here ensures a secure connection between the parts 25a, 25b, 26a, 26b. Thus, e.g. the longitudinal part 25a are not separated from the transverse part 26b when a force acts on the transverse part 26b which points outwards in the plane of the sheet according to FIG. 6 or points downwards in the plane of the sheet according to FIG.

The respective connecting element 29a, 29b is not positively in the. Bag 30a, 30b, so that a Gaps result in which an insert 31, such as a plastic insert, can be inserted. Instead of an insert 31, the intermediate space can also be filled with an adhesive, for example hard foam or casting resin, or another suitable filler. Since the connection does not need to be form-fitting, the requirements for the manufacturing tolerances can be kept low and thus cost-effective production can be achieved. Any inaccuracies in the production are compensated by the use of the insert 31 or the filler.

The two longitudinal parts 25a, 25b and the two transverse parts

26a, 26b are each made in one piece from metal or plastic. The provision of several parts has the advantage that support frames 20 of different widths can be easily produced by producing transverse members 26a, 26b of different lengths. If the parts 25a, 25b, 26a, 26b are cast from metal, the multi-part also has the advantage that the place in the

Mold boxes are optimally utilized and therefore the largest possible number of support frames 20 can be produced per casting process. i The cover is assembled as follows:

The parts 25a, 25b, 26a, 26b are assembled to the frame 20 by inserting a respective insert 31 into the pockets

30a, 30b inserted and the connecting elements 29a, 29b are pressed. Is in place of the inserts 31 a

Provided filler, it is in the respective space between the connecting element 29a, 29b and bag 30a, 30b attached. The support frame 30 is placed and fixed on the gutter body of the drainage channel, for example by gluing and / or setting in concrete. When Channel bodies are the usual channels for draining the water used.

The cover grid 10 is placed on the support frame 20 by placing one of the two hooks, e.g. IIa, under the one of the

Holding elements, e.g. 22a, and a force is exerted against these holding element 22a, so that the opening 21a can be reduced in size and the other hook IIb can be inserted under the other holding element 22b. Due to the elasticity of the retaining element 22a, this assumes the original position again, so that finally the cover grid 10 is secured to the support frame 20 is held.

To remove the mounted covering grate 10, a suitable tool is gripped between the two inlet openings 14 ', which are arranged on the left and right of that inlet opening 14 where the hook IIa or IIb is located (see FIG. 5), and the retaining element 22a or 22b pressed to the side, so that this releases the hook IIa or IIb and the cover grid 10 can be pulled upwards.

From the foregoing description, numerous modifications will be apparent to those skilled in the art without departing from the scope of the invention, which is defined by the claims.

For example, it is conceivable to use resilient tongues as holding elements for the hooks IIa, IIb. FIGS. 9 and 10 show a possible embodiment of the covering grid 10 'or supporting frame 20', components which correspond to the components of the embodiment according to FIGS. 5 and 6 being provided with the same reference numerals. As shown in FIG. 9, the cover grille 10 'comprises in the end region of its two transverse sides two opposing hooks 11c and Hd or He and Hf. The hooks Hc-Hf are formed on the cover grate 10' like the hooks Ha, Hb of the first embodiment.

As shown in FIG. 10, the longitudinal part 25 'a of the support frame 20' each at its two ends with a slot 21c, 2Ie, provided, which is formed as a through hole. This results in each case a resilient tongue 22c, 22e, which can be pressed to the outside, whereby the width of the slot 21c, 21e is reduced. The longitudinal part 25'b is formed substantially equal to the longitudinal part 25'a and is provided with slits 2Id and 2If for forming a tongue 22d opposite to the tongue 22c and a tongue 22f opposite to the tongue 22e.

For placing the covering grid 10 ', the hooks which are located on the same longitudinal side of the covering grid 10', e.g. the hooks Hc and He are pushed under the two tongues of the same longitudinal part, e.g. the tongues 22c and 22e, and pushed away these tongues, so that the two other hooks Hd and Hf can be pushed under the other two tongues 22e and 22f.

As a further modification, it is conceivable to provide holding elements in the manner of the holding elements 22a-22f on the opposite transverse parts 26a, 26b and to arrange hooks in the manner of the hooks Ha-Hf on the supporting frame 10 in such a way that they can be brought into engagement with the holding elements ,

The hooks Ha and Hb, Hc and Hd and He and Hf need not be located exactly opposite each other, but may also be laterally offset from each other. It is also conceivable, the holding elements of the support frame in such a way that on the one hand a resilient web in the manner of the web 22a or 22b is located and on the other side at least one resilient tongue in the manner of the tongue 21c - 2If.

Furthermore, the cross members 26a and 26b are not necessary to hold the cover grate. Fig. Il - 14 show a third embodiment, in which only two longitudinal parts 25 '' a and 25 '' b as a support for the cover grid

10 '' serve. As in the case of the first embodiment according to FIG. 1, this has hooks IIa and IIb which can be brought into engagement with a holding element formed on the longitudinal part 25 '' a or 25 '' b, respectively.

The two longitudinal parts 25 '' a and 25 '' b are formed substantially the same. The following description of the longitudinal part 25 "b applies analogously to the longitudinal part 25" a.

To form the retaining element for the hook IIb, the longitudinal part 25 '' b is provided with a slot, as in the first embodiment according to FIG. 1, so that a resilient web 22b results. In contrast to the first embodiment, the support surface 27b, which is arranged on the projecting portion of the longitudinal part 25b, additionally through openings 24. Through these lugs 15 formed on the cover grid 10 '' can be passed.

As shown in FIGS. 11 and 14, the cover grid 10 '' is provided on its two longitudinal sides with lugs 15 which extend in the direction of attachment 17, in which the cover grid 10 '' on the longitudinal parts 25 '' a and 25 '' b placed becomes. The respective nose 15 has a tapering in Aufsetzrichtung 17 shape. In the present example, the nose is 15 W

- 11 -

in the front view according to Fig. 11 and in the side view according to FIG. 14 conical. Seen in the direction of placement 17, the tabs 15 protrude beyond the hooks IIa and IIb. 5

As shown in FIGS. 12 and 13, the openings 24 are adapted to the shape of the respective nose 15 and have a correspondingly tapered shape. 0 If the cover grid 10 '' placed on the longitudinal parts 25 '' a and 25 '' b, the lugs 15 engage in the openings 24, before then the hooks IIa and Hb under the respective holding element on the carrier 25 '' a, 25 ' ^! b engage. 5 The lugs 15 and openings 24 serve to specify the distance between the two longitudinal parts 25 '' a and 25 '' b so that they have the correct position with respect to the cover grid 10 ''. This is particularly advantageous if the longitudinal parts 25 ^{r ι} a and 25 '' b are mounted in the drainage channel, for example by

Gluing and / or setting in concrete.

By omitting the cross members 26a and 26b, a particularly simply designed carrier for the cover grille 5 '' is provided.

The locking described here by means of hooks and

Holding element is of course also with others

Embodiments of the carrier usable. For example, the support may be formed as a one-piece support frame and / or be provided directly on the gutter body, in that the longitudinal sides in the form of side parts are formed with retaining elements in the manner of the retaining elements 22a, 22b and / or 22d-22f. Conversely, the multi-part support frame described here 5 according to FIG. 6 or 10 be used in other types of locking the Δbdeckrostes on the carrier.
