AI Technical Summary
Existing window sill drainage systems fail to effectively prevent driving rain from penetrating the connection between window components and the building structure, leading to water ingress and damage.
A rainwater drainage system is installed as a recessed or overlapping seal on the outer frame sides, collecting and draining water away from the frame grooves to the outside, while sealing them.
Effectively collects and drains water from the window frame grooves, preventing water ingress and sealing the grooves to protect the building structure.

Abstract
Description
1 Description
[0001] The invention relates to a rain drain mounted on the outer frame grooves for building elements such as windows and doors in order to drain away the water penetrating these grooves. 2 State of the art
[0002] Various devices exist for window sills to collect and drain any water that penetrates the sill area. These are often installed as a seal beneath the window sill. Because the guide rails are usually recessed, the window sills and the seal beneath them are often narrower than the frame width. Furthermore, the frame grooves are located behind the seal, and the sealing layer does not extend behind the frame grooves. 3 Problem statement
[0003] The invention described in claim 1 addresses the problem that driving rain penetrates the connection to attached components, e.g., between the window and the sunshade or into the sunshade boxes, and runs down the sides of the window in the frame grooves. The water then reaches behind the window sill seal and penetrates the building structure. 4 Solution
[0004] This problem is solved by the features listed in the claim. 5 Benefits Achieved
[0005] By using the rainwater drainage system for frame grooves, as a recessed or overlapping seal on the outer sides of the frame, water running down the window frame is collected and drained to the outside. At the same time, the frame grooves are sealed. 6. Description of an example
[0006] Example of implementation based on Fig.1 The driving rain drain (1) is recessed and attached to the window frame (2), above the connecting profiles (6), in such a way that it seals and overlaps the frame grooves (3) and drains outwards under the window sill (4) via the corner seal (5).
Claims
[1] Driving rain drainage for window frames characterized by that it seals the frame grooves downwards, surrounds them and directs moisture outwards. [2] Driving rain drainage according to claim 1, characterized by that it is made of a solid or soft material. [3] Driving rain drainage according to claim 1, characterized by that it also seals the grooves. [4] Driving rain drainage according to claim 1, characterized by that it is led to the outside under the windowsill. [5] Driving rain drainage according to claim 1, characterized by that this only drains a part of the frame side, e.g., a frame groove. [6] Driving rain drainage according to claim 1, characterized by that this drains the entire frame side or all frame grooves.
