Title; Automatic downpipe flap

<The invention relates to an automatic downpipe flap,

which is built into the downpipe and in the case of heavy and moderate precipitation the runoff into the sewer system prevents and also allows other use of the rainwater.

(If there is very little precipitation, the water runs into the.

( Sewer network from.

J 10 Same at the beginning of heavy precipitation, namely until the container (11) is filled.

,' State of the art:

^! I There are manual as well as a rain barrel float

operated downpipe flaps known.

However, these water flaps either always or depending on the level in the collecting tank conduct the rainwater '25 from the downpipe.

Task; The invention is based on the object of removing only relatively clean rainwater from the downpipe. It can then be used in septic tanks to enrich the groundwater or in rain barrels. The deposits (soot etc.) on the roofs or other-. ren areas are with the 1st downpour in the sewer

The invention relates to £: a downpipe flap that is used in heavy and moderate rain drains the water from the downpipe ..

The function of the DI can be described as follows: At the beginning of rain, the rainwater in the downpipe runs through the fall water centering (1) and arrives at the tank inlet sieve (9). Only part of the incoming water enters the container (11) through the container inlet sieve (9). The remaining water runs along with coarse dirt past the container (11) into the sewer network. If the inflow into the container (11) is greater than the outflow through the container outlet (12), the container (11) fills and slowly closes the flap (8) via the pull rope (6). In this transition phase, part of the water runs through the sieves with storage area (k) on the flap (8). The container (ii) fills up more and more and closes the flap (8).

Now the Yasser is diverted. To stay in the closed position, the

2 ^ Filters with storage area (k) allow more water to flow into the container (11) than can flow out through the container outlet (12).

When the rain becomes too weak, this is no longer the case Case and the flap (.3) is held by the return spring

(3) reopened.
