Arrangement of roller blinds for windowOgMerefot horizontally divided into two parts.

Technical field

The present invention relates to a window which is horizontally divided into two parts, the upper wing of which is pivotable about a horizontal pivot axis at its upper end and the lower wing is either fixedly fixed or is pivotable about a horizontal pivot axis at its lower end. It is provided with a roller blind arrangement with an outer roller blind guided in the side guide rails, which is wound and unwound by a winding shaft in the end region of the window, each of the guide rails being formed in two parts. On the upper guide rail and on the lower guide rail, a horizontal line dividing the window, the faces facing each other, lies under the slit at the location of the window.

BACKGROUND OF THE INVENTION

A one-piece roof window with a combined roller shutter arrangement is known, for example, from DE 197 37 263 A1. French Patent Application No. 2,307,115 also discloses a roller shutter arrangement in which the outer roller shutter can be guided in a fixed guide rail and a pivoting guide rail, the two guide rails being connected to each other by a hinge. This equipment of the roller shutter arrangement, together with the guide rails, helps to easily control the deflection of a part of the roller shutter arrangement from the interior through out pulling up and lowering the external roller shutter, but is less suitable as a combination with a two-part window. only with the window closed. However, the present invention is intended for a horizontally divided window into two parts, in particular for a roof window, in which the lower part of the window is either fixedly mounted or pivotable about a horizontal pivot axis

.............. 1-down end of bottom part. As long as, especially in roof windows, the roller shutter arrangement is always mounted on the window sash or the window frame, the problem of the desired shading of the entire glazed window surface with respect to its division into two parts remains.

SUMMARY OF THE INVENTION

The present invention is based on a definition of this problem, the object of which is to enable the entire glass surface of the window to be shaded horizontally into two parts.

This object is achieved in that, in the roller shutter arrangement, the characteristics of which are described in the introduction, each of the two guide rails is formed of two parts, one upper guide rail and one lower guide rail, with their faces facing one another. opposite to each other at the horizontal line of the window splitting below the left slot, and at least one face just against the other face is free to pivot.

The advantage of this roller blind arrangement is, on the one hand, that the top blind of the roller blind completely covers the window when the window is closed and, on the other hand, the two-part design of the guide rail allows the upper wing to overlap when it is opened. A further advantage is that the upper and lower sash of the window, each separately, can be partially opened independently of each other, while maintaining the blind arrangement, i.e. while maintaining complete shading. Therefore, in the case of repair, the outer blind of the roller blind formed from the bar screening elements can be pulled out of the lower guide rails when the wings are opened by the bar shielding element being pulled out on the side and the outer blind shutter being split.

Preferred further embodiments of the invention are set forth in the following claims.

In order to prevent sliding friction between the upper guide rail and the lower guide rail when the upper window sash is opened, the two rails in the region of the longitudinal dividing line are additionally formed by oblique cuts.

A particularly preferred further embodiment of the invention is that a switch is provided in the upper guide rail, which connects the current circuit to the roller winding motor only when the window is closed. This prevents the shade blind from running out of the split guide rail in case of incorrect handling. The contact switch can be operated by a cam switch at a certain position on the lower window frame. To facilitate removal of the roller shutter elements in the event of repair, a plug can be built into the connection cable, which must be placed under the roof covering. It can also include a solar control that supplies the winding motor with operating voltage via the corresponding collectors and control unit.

An advantage of a further embodiment of the invention is that a driving shaft is provided which is arranged in the lower region of the upper guide rails transversely between the upper guide rails and at each end of which a driving winding roller is guided in each guide groove parallel to the upper guide rails. . Thus, the side guide rails of the roller shutter arrangement at the lower end are slid onto the drive winding rollers and slid onto the upper retention angular device.

The driving shaft is preferably mounted on the right and left driving brackets. These are fixed to the sash. The driving shaft and the driving bracket form the lower housing of the complete roller shutter.
