SK15372001A3 - Roller shutter arrangement for windows that are horizontally divided into two parts - 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.

Arrangement of the roller blind on the window, which is 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 shutter arrangement with an outer roller shutter 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, the faces face one another below the left slot at the point of the horizontal window dividing line which face each other.

BACKGROUND OF THE INVENTION

A one-piece roof window with a combined roller blind arrangement is known, for example, from DE 197 37 263 A1. French patent application number FR 2 307 115 also shows a roller blind arrangement in which the outer roller blind can be guided in a fixed built-in guide rail and in a pivoting guide rail, the two guide rails being connected to each other by a hinge. This feature of the roller blind arrangement, together with the guide rails, facilitates easy control of the deflected part of the roller blind arrangement from the interior by pulling upwards and lowering the outer roller blind, but is less suitable than a combination with a two-part window. with the window closed. However, the present invention is directed to a horizontally divided window into two parts, in particular a roof window, in which the lower part of the window is either fixedly mounted or pivotal about a horizontal pivoting axis at the lower end of the part. If, in particular in the case of roof windows, the roller shutter arrangement is always mounted on the window leaf or the window frame, the problem of the desired shading of the entire glass pane of the window with respect to its division into two parts remains.

SUMMARY OF THE INVENTION

The present invention is based on the definition of this problem, the object of which is to allow the shading of the entire glass surface of the window, horizontally divided into two parts.

According to the invention, 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, their facing faces facing each other. each other in the place of the horizontal window splitting line below the slot, and at least one face just against the other face is free to pivot.

Λ

An advantage of this embodiment of the roller blind is, on the one hand, that the top blind of the blind covers the window completely when the window is closed and, on the other hand, the two-part design of the guide rail enables the upper wing to be covered when opened. A further advantage is that the upper and lower sash, each separately, can be partially opened independently of each other, while maintaining the blind arrangement, i.e. while maintaining full shade. Therefore, the outer blind of the blind formed from the bar shielding guide rails in the event of repair can be pulled out of the lower guide rails when the wings are opened by the rod shielding element being extended laterally and the outer blind blind divided.

Further preferred 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, both rails in the region of the longitudinal dividing line are additionally formed by an oblique cut.

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 the event of mishandling. The contact switch may be actuated by a cam switch mechanism at a certain position on the lower window frame. In order to facilitate the dismantling of the roller shutter elements in case of repair, a plug may be built into the connection cable, which must be laid under the roof covering. It may also include a solar control that supplies the winding motor with operating voltage by means of corresponding collectors and a control unit.

It is an advantage of a further embodiment of the invention that a driving shaft is provided which is arranged in the lower region of the upper guide rails across the upper guide rails and at their ends is always attached to a guide winding roller which extends in each guide groove parallel to the upper guide rails. . Thus, the lateral guide rails of the roller shutter arrangement at the lower end are slid onto the drive winding rollers and slid onto the upper retention angle device.

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

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows an overall view of the roller shutter arrangement according to the invention with the window open, with the external roller shutter 6 guided in the side guide rails 2, 4 and which is wound and unwound on the winding shaft 8 located in the end region of the window. Accordingly, the side guide rails 2, 4 open at one end into a roller shutter box 23 in which a winding shaft 8 is rotatably mounted for winding the outer roller shutter 6. It is assumed that the winding shaft 8 is equipped with an electric drive for winding the outer roller shutter 6. of the two guide rails 2, 4 is two-piece, is divided into the upper guide rail 1, 3 and the lower guide rail 5, 7 in such a way that their faces 9, 11 face each other and lie opposite each other at the dividing line 10 windows. In the lower region of the upper guide rail 1, 3, there is a driving shaft 14 arranged between the upper guide rails 1, 3. This driving shaft 14 at each of its ends 14, 15 has a rotating driving roller 17, 18 mounted in a known manner, not shown. . The rotary drive rollers 17, 18 are guided in the guide groove 19, 20 in parallel to the upper guide rails 1, 3. The drive shaft 14 is mounted by means of the right and left driving brackets 21, 22, which are fixed to the window sash. The lower end regions of the lower guide rails 5, 7 are interconnected by means of the connecting bar 24 and represent the end impact of the outer roller shutter 6 in the unwound state.

Fig. 2a shows a side view of the roller blind arrangement according to Fig. 1 with a detailed cut-out in the region of the shaped connection between the two sashes in the state where the top sash of the window is open.

FIG. 2b shows an enlarged detail view where, for example, a mechanical switch cam is positioned on the lower window frame 27 in such a way that it is seated under the safety limit touch button 26. The switch cam 25 must be adjusted so that its peak reaches the safety limit touch button 26 and easily switched when the window sash is closed. The safety limit button 26 only allows the roller shutter to be operated in the closed state, so that the external shutter does not come out of the split guide rails in case of incorrect operation.

Fig. 3 shows a schematic overview of the shutter arrangement according to the invention when the top wings of the window are closed.

Fig. 4a shows a side view of the shutter arrangement according to Fig. 3, with a partial cut-out in the region of the molded locking connection between the two sashes in the state of closing of the upper sash.

Fig. 4b shows an enlarged detail of Fig. 4a. In the state of closing of the upper window sash, the facing surfaces 9, 11 of the upper guide rail 13 and the lower guide rail 5, 7 face each other below the slot 12. The switch 13 closes the current circuit for the winding roller winding motor.
