"Balcony drain (roof drain) with odor trap"

S'ch relates the innovation to a balcony drain (Roof drain) with odor trap, consisting of a drain pipe in which a circular cylindrical top is coaxially Attachment part is used with a cover grate.

The drainpipe of the BalkonahJaufes is inserted into the concrete ceiling poured. A collar is attached to the upper edge of the drain pipe, to which a sealing membrane can be connected. In the area of the attachment, the floor screed, possibly

State-of-the-art balcony drains either have no odor trap at all or one that does not work! Water _; which can freeze at F ^ ost.

The task of the innovation is to be seen in a balcony drain or Pich drain with one to develop permanently functional odor trap.

This problem is solved by a balcony drain with the features according to the protection claim.

In the case of a balcony drain, the closure part used in the attachment forms a barrier against rising Odor gases. The flap of the closure part is closed because it is due to its own weight is on the assigned seat. If water occurs, it is absorbed through the drainage channel and can continue to flow through the drainage opening, whereby the flap opens automatically due to the water pressure and closes again when the flow of water stops. The closure part of the balcony drain is a

relatively simple and uncomplicated molding. It can be removed for cleaning at any time and be used again. Subsequent installation is also possible. The drain pipe can be a standard version.

In the following, an embodiment of the innovation is described with reference to enclosed drawing. It represents a longitudinal section through a balcony drain (roof drain) with odor trap according to the innovation.

The balcony drain essentially consists of the drain pipe 1 with a circular cross-section and a Attachment 10, which also has a circular cross-section and is inserted into the drain pipe 1 at the top is. The attachment 10 is based on a circular shoulder 2 of the drain pipe 1 from. A circular edge 3 adjoins the shoulder. There is a sealing ring a collar 4 clamped on as an intermediate bearing.

The top part 10 takes on a grate 13, for the support of which a shoulder 12 is formed, softer has the same shape as the grate, usually a square shape. Under the square Paragraph 12 is a circular paragraph 11 integrally formed, where a closure part with a circular Collar 21 is supported. Another collar 22 is molded onto the closure part. The groove between the two collars 21 and 22 receives a sealing ring 23, which is attached to the inside of the wall of the attachment

part 10 is present.

Approximately at the level of the channel 22, the cross section of the closure part 20 is over half through a segment-shaped bottom 24 completed, which merges into a flat wall 25b. Through this wall and through a cylindrical channel wall 25a, a drainage channel which is segment-shaped in plan view is formed 25 limited. In these. Channel can penetrate water that is essentially perpendicular Drain opening can drain. The drainage opening is closed by a flap 26 which is suspended from hinge elements 25c. The flap is due to its own weight on a slightly inclined seat 25d. 25e is the bottom of the drainage channel.
