DE29907720U1 - Roller shutter arrangement for horizontally split windows - Google Patents

Abstract

Disclosed is a roller shutter arrangement for windows, especially roof windows, that are horizontally divided into two parts. The inventive arrangement comprises a roller shutter (6) that is guided in lateral guiding rails (2, 4) and that can be wound and unwound on a roller shaft (8) in an end area of the window. The aim of the invention is to enable the entire glass surface of the window that is horizontally divided into two parts to be in the shade. Each of the two guiding rails (2, 4) is divided into two parts, i.e. an upper guiding rail (1, 3) and a lower guiding rail (5, 7). The front faces (9, 11) thereof facing each other are located opposite each other on the horizontal separating line (10) of the window while a gap (12) is left open.

Roller shutter arrangement for horizontally split windows

Description

The present invention relates to a roller shutter arrangement for horizontally divided windows, in particular for roof windows, with a roller shutter curtain guided in lateral guide rails, which can be wound up and unwound on a winding shaft at an end region of the window.

A roller arrangement for a one-piece roof window is known, for example, from DE 197 37 263 A1. However, the present invention is aimed at horizontally two-piece windows, and in particular roof windows, in which the lower part of the window is either fixed or designed to pivot about a horizontal pivot axis at the lower end of the lower part. Since a roller shutter arrangement is always mounted on the window sash, especially in roof windows, the problem arises when shading the entire glass area of the window is desired in order to divide it into two parts.

The present invention addresses this problem, and its task was to enable shading of the entire glass surface of a window divided horizontally into two parts.

This object is achieved according to the invention in a roller shutter arrangement with the features described above in that each of the two guide rails is divided into an upper guide rail and a lower guide rail, the

facing ends are opposite each other at the horizontal dividing line of the window, leaving a gap.

This design of the roller shutter arrangement has the advantage that, on the one hand, the continuous roller shutter cover covers the entire window when the window is closed and, on the other hand, the two-part guide rails enable the upper sash to be covered when it is open. A further advantage is that the upper and lower sashes of the window can be opened a crack independently of one another even when the roller shutter arrangement is lowered, i.e. while maintaining complete shading. In addition, the roller shutter, which is made up of the roller shutter slats, can be pulled out of the lower guide rails by opening the sash in the event of a repair so that the defective roller shutter slat can be pushed out to the side.

Advantageous further developments of the invention are specified in the subclaims.

In order to prevent sliding friction between the upper guide rails and the lower guide rails when opening the upper window sash, the two rails are cut at a complementary angle in the area of the gap.

A particularly advantageous development of the invention is that a switch is arranged in the upper guide rail in such a way that the circuit for the roller shutter winding motor only closes when the window is closed. This prevents the roller shutter from running out of the divided guide rails due to incorrect operation. For example, the switching contact can be activated in a certain position by a mechanical switching cam positioned on the lower window frame. To make it easier to dismantle the roller shutter box in the event of repairs, a plug connection can be built into the connecting cable, which must be placed under the roof covering. A solar control system can preferably be integrated.

An advantageous further development of the invention is provided in that a driver shaft is provided which is arranged in the lower area of the upper guide rails transversely between the upper guide rails, and at each end of which a rotatable driver roller is attached, which is guided in a guide groove parallel to the upper guide rails. The lateral guides of the roller shutter arrangement are thus pushed onto the driver roller at the lower end and attached to the upper bracket.

Preferably, the drive shaft is held by a right and a left drive bracket, which are attached to the window sash. The drive shaft and the drive brackets form the lower bearing of the complete roller shutter.

In the following, a preferred embodiment of the invention is explained in more detail with reference to a drawing.

Fig. 1 shows a schematic overall view of a roller shutter arrangement according to the invention with the window sash open, with a roller shutter curtain 6 guided in lateral guide rails 2, 4, which can be wound up and unwound on a winding shaft 8 at an end of the window. The lateral guide rails 2, 4 each open at one end into a roller shutter box 23, in which the winding shaft 8 for winding up the roller shutter curtain 6 is rotatably mounted. This winding shaft 8 is provided with an electric drive motor for winding up the roller shutter curtain 6. Each of the two guide rails 2, 4 is divided into two parts, an upper guide rail 1, 3 and a lower guide rail 5, 7, in such a way that their mutually facing end faces 9, 11 are opposite one another on the horizontal dividing line 10 of the window. In the lower area of the upper guide rails 1, 3, a driver shaft 14 is arranged transversely between the upper guide rails 1, 3. This driver shaft 14 has a rotatable driver roller 17, 18 at its ends 15, 16 in a manner not shown but known, which are each guided in a guide groove 19, 20 parallel to the upper guide rails 1, 3. The driver shaft 14 is held by a right and a left driver bracket 21, 22, which are attached to the window sash. The lower end areas of the lower guide rails 5, 7 are connected to one another via a connecting strip 24, which represents the end stop for the roller shutter curtain 6 in the unrolled state.

Fig. 2a shows a side view of the roller shutter arrangement according to Figure 1 with a partial section in the area of the form-fluid connection between the two window sashes in the open state of the upper window sash.

Fig. 2b shows an enlarged partial section. For example, a mechanical switching cam 25 is positioned on the lower window frame 27 in such a way that it sits under a safety limit switch 26. The switching cam 25 must be adjusted in height so that the safety limit switch 26 switches easily when the sash is closed. The safety limit switch

26 allows the roller shutter arrangement to be operated only when it is closed in order to prevent the shutter from running out of the divided guide rails due to incorrect operation.
