Description

[0001] The invention relates to a cover for a street drain, comprising a frame made of two interlocking parts, an inner part and an outer part, specifically according to the features of the independent claims. The invention further relates to a street drain comprising the cover according to the invention and to the use of the cover according to the invention in a street drain.

[0002] Existing storm drain covers often consist of individual, permanently mounted components, which can make installation and maintenance difficult. These conventional covers often offer little flexibility in terms of position adjustment and are complicated to install, as they do not allow for easy adjustment or tool-free repositioning. Furthermore, leaks between components are common in such systems, which can impair drainage functionality.

[0003] The object of the present invention is to provide a cover for a street drain that is easy to install and allows flexible adjustment of the position of the inner part relative to the outer part. Furthermore, the cover should ensure a reliable seal and be characterized by tool-free assembly.

[0004] The problem is solved by the attachment according to the invention, comprising a frame made of two interlocking parts, an inner part and an outer part. The dependent claims describe particularly preferred embodiments of the invention.

[0005] An attachment for a street drain according to the invention comprises a frame made of two interlocking parts, an inner part and an outer part, wherein the inner part and the outer part are preferably each made of sheet metal, the attachment can be placed on a drainage shaft of the street drain, and the position of the inner part relative to the outer part is detachably adjustable by means of adjustment means. Other materials instead of sheet metal, such as cast iron, plastics, or fiber-reinforced polymers, are also conceivable.

[0006] According to the invention, the inner and outer parts are arranged such that a gap remains between them, which can be filled by means of a seal, in particular a sealant. This design ensures a reliable seal and prevents the ingress of water or dirt. Furthermore, the load-bearing capacity can be improved. The seal, in particular the sealant, can preferably be based on a polymer, such as EPDM, and / or a mortar. The attachment thus encompasses the seal.

[0007] Preferably, the seal, in particular the sealant, has a compressive strength (23°C and 50% relative humidity) according to DIN EN 196-1 (prism 4x4x16 cm) of at least 10 N / mm², preferably at least 30 N / mm², more preferably at least 55 N / mm², and even more preferably at least 80 N / mm². The compressive strength is typically in the range of 10 N / mm² to 500 N / mm².

[0008] Preferably, the seal, in particular the sealant, has a flexural strength (23°C and 50% relative humidity) of at least 2 N / mm², preferably at least 5 N / mm², more preferably at least 7 N / mm², and even more preferably at least 10 N / mm². The flexural strength is typically in the range of 2 N / mm² to 50 N / mm².

[0009] Preferably, the seal, in particular the sealant, has a dynamic modulus of elasticity (at 23°C and 50% relative humidity) of at least 10,000 N / mm², preferably 20,000 N / mm², more preferably 30,000 N / mm², and even more preferably at least 40,000 N / mm². The modulus of elasticity is typically in the range of 10,000 N / mm² to 100,000 N / mm².

[0010] Preferably, the sealant, in particular the sealant compound, has a swelling capacity (at 23°C and 50% relative humidity) of at least 0.01 vol.%, preferably at least 0.05 vol.%, and more preferably at least 0.1 vol.%. The swelling capacity is typically in the range of 0.01 vol.% to 1.0 vol.%.

[0011] Preferably, the seal, in particular the sealant, is shrink-free.

[0012] Advantageously, the attachment comprises a box-shaped frame, in which the inner and outer parts are also box-shaped. The inner part has two inwardly curved long edges and two outwardly curved short edges on its sides facing the street drain frame. This design ensures a stable connection and better adaptation to the street drain.

[0013] The outer part can form a frame that extends beyond the outer dimensions of the inner part, allowing it to accommodate the inner part.

[0014] Preferably, the inner part includes a base plate that connects to the long and short edges and defines the opening of the drainage shaft. This ensures a secure and precise covering of the drainage opening.

[0015] In a particular embodiment, the base plate of the inner part has threads at the corners between the short and long edges, preferably formed by rivet nuts and connected to the base plate. This enables a stable fastening of the adjustment elements.

[0016] Preferably, the outer part includes a base plate with an opening that is designed to be complementary to the opening of the base plate of the inner part, so that both openings overlap. This design ensures a precise fit and optimal coverage of the drain shaft opening.

[0017] Advantageously, screws are guided through the threads of the inner part and arranged resting on the base plate of the outer part, with the screws serving to adjust the position of the inner part relative to the outer part. In particular, the screws are designed to allow tool-free assembly, for example as knurled nuts. This simplifies handling and saves time during installation.

[0018] In a particular embodiment, the inner and outer parts are stamped and bent components, preferably made of a corrosion-resistant material, especially a non-corrosive sheet such as galvanized or stainless steel. The stamped and bent components can be manufactured from a single piece or multiple pieces and are joined at the overlapping edges by force-fit and / or form-fit, particularly by riveting or welding. This design increases the durability and corrosion resistance of the attachment.

[0019] A street drain according to the invention comprises a drain frame and a cover, wherein an attachment according to the invention is provided between the drainage shaft and the street drain.

[0020] A drain cover is preferred. This combination ensures a robust and functional cover for the drain.

[0021] Furthermore, the present invention relates to the use of an attachment according to the invention in a street drain.

[0022] The advantages of the invention will now be explained in more detail using a preferred embodiment and the figures.

[0023] It shows: Fig. 1 shows a schematic representation of the inner part of the attachment according to the invention for a street drain; Fig. 2 shows the outer part of the attachment according to the invention; Fig. 3 shows the assembled attachment, in which the inner part is inserted into the outer part and a street drain (shown in dashed lines) is placed on top.

[0024] Fig. 1 Figure 1 shows a schematic representation of the inner part 10 of the inventive cover for a street drain. The inner part 10 is box-shaped and made of sheet metal. It comprises two inwardly bent long edges 11 and two outwardly bent short edges 12. These edges serve to support a [missing information - likely a specific component or element]. Fig. 3 The street drain 50 shown (shown with dashed lines) is located here. Furthermore, the inner part 10 includes a base plate 14, which connects to the long edges 11 and short edges 12. The base plate 14 defines an opening 16, which, when the extension is installed, overlaps with the opening of the drainage shaft (not shown). This base plate 14 thus defines the area through which the water enters the drainage shaft.

[0025] Threads 13 are provided on the base plate 14 at the corners between the long edges 11 and the short edges 12; these threads are preferably formed by rivet nuts. These threads 13 serve to receive screws 15 (see Fig. 3 ) for adjusting the position of the inner part 10 relative to the outer part 20 (see Fig. 2 and 3 ).

[0026] Fig. 2 Figure 1 shows the outer part 20 of the attachment according to the invention. The outer part 20 is also box-shaped and, like the inner part 10, is made of sheet metal. It comprises a base plate 21, which has an opening 22 that is designed to be complementary to the opening 16 of the base plate 14 of the inner part 10 (see Figure 2). Fig. 1 ), so that both openings 16, 22 overlap when the inner part 10 is inserted into the outer part 20. The complementary design of the openings 16 and 22 ensures a precise fit, which optimizes water drainage. The outer part 20 is designed so that, when the attachment is assembled, a gap remains between the inner part 10 and the outer part 20, which can be filled with a sealant, in particular a sealant compound. This ensures a reliable seal and prevents dirt or water from penetrating the gap.

[0027] Fig. 3 Figure 1 shows the assembled attachment, with the inner part 10 inserted into the outer part 20. As can be seen, the threads 13 of the inner part 10 engage through the base plate 14 of the inner part 10, so that the ends of the screws 15 screwed into it rest against the base plate 21 of the outer part 20. The screws 15 are guided through the threads 13 and rest on the base plate 21 of the outer part 20, and serve to adjust the position of the inner part 10 relative to the outer part 20. Depending on how deeply one of the four screws 15 is screwed into the respective thread 13, the inner part 10 shifts relative to the outer part 20.

[0028] The screws 15 are particularly advantageous when designed as knurled nuts or wing nuts, which enables tool-free assembly.

[0029] By loosening or tightening the screws 15, the position of the inner part 10 relative to the outer part 20 can be easily adjusted. Once the desired position is reached, the tightened state of the screws 15 ensures that the inner part 10 remains securely fixed in the desired position. The gap remaining between the inner part 10 and the outer part 20 can be filled with a sealant to prevent the ingress of water or dirt. The sealant also contributes to the long-term load-bearing capacity.

[0030] The figures illustrate the interaction of the inner part 10 and the outer part 20, as well as the function of the adjustment mechanism using the screws 15, which engage through the threads 13 of the inner part 10 and rest on the base plate 21 of the outer part 20. This ensures a precise fit and a reliable seal of the entire assembly on the drainage shaft.

[0031] On the in Fig. 3 The attachment shown is then placed on the street drain.

[0032] A major advantage of the invention is the adjustment via the screws 15. This saves assembly time and allows for millimeter-precise adjustment of the attachment, even in three dimensions. The easy adjustability facilitates handling during the construction phase and makes subsequent adjustments effortless.

[0033] A further advantage of the invention is that the complicated and time-consuming process of shimming with mortar or other materials is eliminated. Instead, the application of the sealant creates a permanent, load-bearing layer between the inner part 10 and the outer part 20. This positive fit permanently prevents settling and sagging, thus avoiding costly and time-consuming repairs.

[0034] The invention creates a permanently load-bearing base layer that remains stable even under high loads. Settlement and subsidence, which often lead to damage to the road drainage system and the surrounding road surface, are thus avoided. This significantly reduces the need for costly repairs and extends the service life of the road drainage system.

[0035] Additionally, reducing the amount of mortar and concrete used contributes to environmental protection, as fewer building materials are required. This leads to a reduction in CO2 emissions both during installation and through the elimination of future renovation work.

[0036] Overall, the invention offers a durable, robust solution for road drains, which impresses with its simple and quick assembly as well as flexible adjustability.
