The invention is intended to disclose a knob arrangement, which is better than known devices, for operating a Venetian blind, or a curtain controlling the entry of light, or similar, to be installed behind a window between its frames. The knob arrangement comprises a cord knob (1) fitted to a hole in the frame, to which the lifting cords of the Venetian blind can be attached, and an attitude-control knob (2), to which the attitude-control elements of the Venetian blind can be attached. In each knob (1, 2) of the knob arrangement, there is a shaft (4, 17), and a body (3, 16), and locking elements (12, 18 - 20, 30) for retaining the knob (1, 2) in the hole in the frame when the knob's (1, 2) shaft (4, 17) is pressed into the hole in the frame. |
