Definitions

  • the invention relates to a funnel for connecting the top or frame of a street gully to a collecting container, the funnel preferably being made of plastic, and a method for producing a funnel made of plastic.
  • Street gullies also called wastewater inlets or gullies, consist of a frame or attachment in which a grate is arranged, a sludge bucket held in the frame or attachment and a collecting container with an outlet which is connected to the sewer network via corresponding connectors.
  • the frame or top of the street gullies is usually made of cast iron or a combination of materials cast iron / concrete.
  • the collecting container is made in a manner known per se from concrete or can also consist of plastic or stoneware. In practice there are different manufacturers for the frames or attachments and for the collection containers, which also differ in their dimensions. In addition to the concrete parts, the collection containers are essentially plastic components that are manufactured using the assembly process.
  • the invention had for its object to provide a funnel, in particular made of plastic, with which it is possible to establish a connection between different frames or attachments and different collection containers, which ensures that the surface water to be discharged or the like is not in the ground reached.
  • the funnel should be inexpensive to manufacture.
  • CONFIRMATION COPY a method for producing such a funnel made of plastic is to be created.
  • the object is achieved by the features specified in claim 1. Suitable design variants are described in claims 2 to 10. A suitable method for producing a funnel made of plastic is the subject of claim 11. A further embodiment of the method is specified in claim 12.
  • the funnel according to the invention is part of a street gully and provides the connecting element between the frame of the street gully and that in the
  • the outlet of the funnel is connected to the drain pipe of the collection container, which is integrated into the sewer network.
  • the outlet piece of the funnel can be connected to the upper part of the collecting container free of pressure and stress.
  • the funnel is designed in such a way that it has an edge on at least two opposite sides, the edges being connected to an extension section which is inclined slightly upwards and which lies as a tightly fitting support on the inner edge region of the frame.
  • the extension sections are arranged symmetrically and have infoige of the projections located in the respective frame in the inner corner areas of a smaller width than the edges.
  • the nominal size of the outlet piece of the funnel is matched to the nominal size of the drain pipe of the respective collecting container, which is standardized for the systems on the market.
  • the collection containers are preferably made of plastic.
  • the invention thus ensures the combination of different frame structures with the respective collection containers. This leads to significant simplifications in the selection and compilation of components for street gullies.
  • the customer can determine the frame or attachment suitable for the intended purpose for the desired collection container.
  • Suppliers of plastic collection containers are no longer bound to use a specific frame or top construction.
  • the funnel is an inexpensive component that can be mass-produced as a plastic part. Compared to funnels made of cast iron, those made of plastic or reinforced plastic offer the advantage of lower manufacturing costs.
  • the extension sections formed on the funnel allow the compensation of certain dimensional differences of the existing frame structures.
  • the extension section molded onto the edge can also be injection molded as a part that can be changed in the angle of inclination, e.g. over a film hinge.
  • the individual, outward-facing edge sections can also consist of plastics of different types and hardness.
  • the funnels can be manufactured in one mold using a two- or three-component injection molding process.
  • FIG. 2 is a top view of a funnel as a cast component
  • FIG. 3 shows a section along the line A-A in FIG. 2,
  • FIG. 5 shows a top view of a funnel made of plastic
  • FIG. 6 shows a section along line B-B in FIG. 5.
  • the road drainage system shown in Figure 1 consists of a support ring 1, which is arranged at a certain distance from the top of the road in the lower concrete of the road surface.
  • the frame 2 In the opening 1a of the support ring 1, the frame 2 is inserted, the circumferential outer shoulder 2a of which rests on the top 1b of the support ring 1.
  • the frame 2 In the installed state of the frame 2, its upper edge 2b is almost flush with the road surface, not shown.
  • the frame 2 has on its underside an annular extension 2c with an inwardly directed shoulder 2d, which serves as a support surface for the funnel 3 to be inserted into the upper opening 2e of the frame 2.
  • the frame 2 is generally made of cast iron and in FIG. 2 an associated funnel 3 in cast iron design is shown as a top view.
  • the funnel 3 proposed according to the invention makes it possible to combine different systems with one another, in particular to be able to connect an existing plastic drainage system to different frame or top systems.
  • the funnel 3 has a downward-pointing tubular section 3a as a discharge piece which can be inserted with a precise fit into the sleeve-shaped extension 4a of the collecting container 4.
  • the pipe section 4b is connected as a plug connection to the outlet pipe 4c of the collecting container 4.
  • the outlet pipe 4c is connected to the buried sewer pipe via a further pipe section.
  • the plastic container can also be constructed differently, the only essential feature in cooperation with the funnel 3 is that the outlet piece 3a is connected to the upper part 4a of the collecting container in a media-tight manner without pressure and stress. If necessary, a sludge bucket 5 can be hung in the opening 3b of the funnel 3, the sloping, inclined outer edge surface 5a of which rests on the inner surface 3e of the funnel 3 corresponding to this. A pivotable handle 5b is attached to the upper section of the sludge bucket 5. Finally, a grating 6 is inserted into the opening 2e of the frame or attachment 2, which rests on the inner shoulder 2f of the frame 2 and whose top edge is flush with the top edge of the frame 2.
  • FIGS. 2 to 6 A funnel 3, preferably made of cast iron, is shown in FIGS. This has an edge 3c on the two opposite narrow sides, which is inclined upwards by a few degrees. Extension portions 3d, which are inclined outwards and upwards, adjoin the two edges 3c. The angle of inclination of these extension sections 3d is approximately 30 ° and is matched to the angle of inclination of the shoulder 2d of the frame 2 on which the funnel 3 rests.
  • the edges 3c with their extension sections 3d in the installed position enable a good fit on the shoulder 2d of the frame 2 and ensure that the water to be drained off is almost completely in the funnel 3 arrives.
  • the extension sections 3d it is possible to compensate for different installation tolerances or slight differences in the length and / or width dimension of the openings 2g of the frame 2.
  • the transition area from the edge 3c to the tubular section or outlet piece 3a of the funnel 3 is designed as a circular section 3e.
  • the outer surface of the outlet piece 3a tapers slightly in the outlet direction.
  • the seal 7 is expedient to seal the existing double-sided free space of a few millimeters by using a seal 7 in order to ensure that the water to be discharged also gets completely into the funnel 3.
  • the seal is not shown in detail in FIG. 2 and only its position is indicated by position 7.
  • the cross section of a suitable seal 7 is shown in FIG. 4.
  • the seal has two flexible side lips 7a and 7b and a downward extension 7c through which the longitudinal gap between the outside of the funnel 3 and the inside of the frame 2 is sealed. If necessary, the cross section of the seal can also be designed differently.
  • the seal 7 can also be fastened to the funnel 3, for example by means of a suitable adhesive connection, or can be fixed in a guide arranged on the outer circumference of the funnel.
  • the funnel 3 shown in FIGS. 5 and 6 consists of plastic and differs from the funnel shown in FIGS. 3 and 4 by a different design of the edge.
  • the funnel 3 has a stable edge 3c on its two narrow sides.
  • a flexible edge section 3f is formed on this edge, e.g. through a film cut that automatically adapts to the angle of inclination of the shoulder 2d of the frame 2 within an angle of inclination of approximately 30 °.
  • a circumferential flexible sleeve 3g is formed on the edge section 3f and runs along the parallel straight longitudinal sides. After the funnel 3 has been inserted into the frame 2, the flexible sleeve 3g lies circumferentially against the inside of the extension 2c of the frame 2, which is rectangular in cross section, against the frame 2.
  • the free space between the long sides of the frame 2 is covered by the flexible sleeve 3g and is therefore completely sealed.
  • the prefabricated plastic funnel can be inserted almost completely tight in the frame.
  • the suspended sludge bucket with its weight then ensures that the flexible edge sections 3f rest with their underside on the shoulder 2d of the frame 2.
  • a funnel made of plastic can also be designed analogously to the funnel according to FIGS. 2 and 3, but it is then expedient to form a circumferential sleeve analogously to the embodiment according to FIGS. 4 and 5.
  • a plastic funnel is that it is designed analogously to that according to FIGS. 2 and 3, but additionally a flexible sealing cover is formed on the long sides, which in the installed position covers any space between the funnel and the frame and at the same time seals .
  • a circumferential elastic seal can also be molded onto the underside of the edge 3c or the extension section 3d, which lies tightly against the funnel in the area of the long sides and covers a possible free gap to the adjacent inside of the frame.
  • it can be produced as an injection molded component from two or three plastic components, only one mold being required.
  • the edge regions which differ in their material properties, can be produced from plastics of different types and hardness, such as, for example, thermoplastic, thermoelastic or elastomeric materials.
