DESCRIPTION:
BRIEF SUMMARY
The invention relates to a roller blind support as claimed in the preamble of claim 1.
The roller blind supports provided at both ends of a roller blind are fixed on the wall or the ceiling prior to fitting of the roller blind. It must then be possible for the bearing pins provided on the ends of the roller blind to be inserted into the bearing parts provided for them. While the bearing pin to be inserted first can be pushed into a bore approximately in the lengthwise direction of said bore provided to accommodate it, a bearing shell for the accommodation of the other pin must be open at the side for the insertion of the pin, in order to form an insertion path for the pin. The roller blind support has a fitting position which differs relative to the vertical direction when it is fitted on a vertical wall or a horizontal ceiling. On the other hand, the bearing part must always have the same predetermined fitted position relative to the vertical direction. This applies not only to the bearing part which for the accommodation of a roller blind pin contains a bearing shell and an insertion aperture which opens, for example, from the top into the bearing shell, but also applies when the bearing part accommodates a drive part for the roller blind and has apertures out of which drive or control elements are conveyed downwards, for example a drag chain.
A roller blind support whose bearing part has a bearing shell for a roller blind pin and can be connected to the fixing part in four different angular positions is known (DE-A 35 26 160), the angular position being selected according to the fitting position of the fixing part (on a wall or on a ceiling, to the left or right of the roller blind). Since roller blinds are generally supplied ready for fitting from the factory, the adjustment of the bearing part on the fixing part must be prepared in the workshop. This is organizationally time-consuming, because each order requires individual workshop processing. It would be simpler if the adjustment could be left to the fitter installing the roller blind. However, in the case of the known devices this is not advisable, because they cannot be adjusted simply enough, and therefore, when the adjustment is carried out by amateurs, errors occur which are then mostly wrongly blamed on the manufacturer.
A roller blind is also known in which a metal angle guide to be fitted on the wall has two fixing apertures at equal distances from the fixing flange, one of which is cross-shaped to accommodate the non-rotatable end of a roller blind, while the other is for the accommodation of a bearing part for the rotatable end of the roller blind (DE-A 23 22 738=FR-A 2184019). Since the bearing part does not have a radial insertion aperture for the shaft to be carried, the bearing part and the fixing aperture provided for its accommodation are designed in such a way that in a first rotated position the bearing part with the shaft therein can be inserted into the fixing aperture and in another rotated position can be secured in the fixing aperture, by locking means.
A rod support comprising a metal angle piece to be fixed on the wall and an accommodation part for the end of the rod is known for holding curtain rods (GB-A-8877/1911). In order to be able to place the accommodation part in a desired accommodation direction, it is rotatably fixed on the metal angle piece. This device is not suitable for mounting roller blinds.
In order to secure a roller blind pin which is rectangular in cross-section in the mounting support of a fixing part, it is also known (U.S. Pat. No. 2,487,648) to mount the mounting support round an annular hasp which is interrupted at one point. For the insertion of the pin the hasp is adjusted in such a way that its interruption is flush with the insertion aperture of the mounting support. It is then turned in such a way that it closes the insertion aperture.
In yet another roller blind support (U.S. Pat. No. 1,379,663) the fixing part has a mounting support for the roller blind pin which has an insertion aperture at
