The invention relates to an end cap for laterally closing a metal window sill, in particular an aluminum window sill with a laterally open end profile into which the window sill can be inserted.

With such a cap available on the market, there is a risk that rainwater will penetrate behind the cap plastered into the masonry and thus cause subsequent damage to the building.

The object underlying the invention is therefore to design the end cap of the type mentioned at the beginning in such a way that the penetration of rainwater behind the end cap into the masonry is prevented.

This object is achieved according to the invention by a driving rain protection fin which is attached to the wall side of the end profile starting from the inside of the window sill of the end profile

is designed to protrude vertically upwards.

Preferably, the driving rain protection fin is designed over a distance that corresponds to the maximum possible thickness of conventional roller blind guide rails and is provided with predetermined breaking points at regular intervals. These predetermined breaking points can in particular begin at a point that corresponds to the minimum thickness of conventional roller blind guide rails. This design ensures that the end cap according to the invention can be adapted to windows with roller blind guide rails of different thicknesses.

A particularly preferred embodiment of the invention is described in more detail below with reference to the accompanying drawing. They show

Fig. 1 a partially sectioned side view of the window sill area of a window with the embodiment of the end cap in the assembled state and

Fig. 2 a side view of the end cap before assembly.

Fig. 1 shows the window sill area of a conventional window with a frame 1, a roller blind guide rail 2 and an aluminum window sill 6.

The aluminum window sill 6 is closed at the side by an end cap, which consists of an end profile 3 that is open at the side and into which the window sill 6 is inserted. The end profile usually consists of an end wall with at least two legs running transversely to it, between which the lateral edge area of the window sill 6 can be accommodated.

In order to prevent rainwater from penetrating behind the end cap plastered into the masonry, a driving rain protection in the form of a fin 4 is provided, which, as shown in Fig. 1, is formed on the wall side of the end profile 3, protruding vertically upwards from the inside of the window of the end profile 3.

As shown in particular in Fig. 2, the fin 4 runs over a certain distance along the end profile 3, which corresponds to the maximum thickness of conventional roller blind guide rails 2, whereby from a point that is preferably equal to the minimum thickness of conventional roller blind guide rails, predetermined breaking points 5 are provided at intervals corresponding to the usual thicknesses of the roller blind guide rails, at which the fin 4 can be broken away. This design allows the end cap to be used on windows with different thicknesses of roller blind guide rails, by only breaking away the protruding part of the fin 4 at the predetermined breaking points. The predetermined breaking points are spaced in accordance with the standard dimensions of roller blind guide rails.

Claims (3)

Protection claims 1. End cap for laterally closing a metal window sill, in particular an aluminum window sill, with a laterally open end profile into which the window sill can be inserted, characterized by a driving rain protection fin (4) which is formed on the wall side of the end profile (3) and projects vertically upwards starting from the inside of the window of the end profile (3). 2. End cap according to claim 1, characterized in that the driving rain protection fin (4) is formed over a distance that corresponds to the maximum possible thickness of conventional roller blind guide rails and is provided with predetermined breaking points at certain intervals. 3. End cap according to claim 2, characterized in that the predetermined breaking points begin at a point which corresponds to the smallest thickness of conventional roller blind guide rails.
