A plummer block for the arm of a Florentine blind with articulated arms, comprising a supporting block (2) which can be clamped to a supporting part, and a bearing block (4) which can tilt about a substantially horizontal axis into the descended position and on which an articulated arm (20) is mounted so as to be able to pivot about an axis aligned transversely to the tilt axis, the bearing block (4) and the supporting block (2) being coupled by a coupling rod (5) which permits and limits the tilting movement and has a thread (8) and adjusting nut (9), and a blocking slide (15) being coupled to the articulated arm (20), which blocking slide is displaceable transversely to the axis of the coupling rod (5) and blocks the same in the descended position. The technical problem is to construct the plummer block such that the functioning of the stop is independent of the blocking slide and that a blocking slide capable of being manufactured in a simple manner can be used. The adjusting nut (9) is constructed as a solid cylinder with thread passage in the radial direction. A cylindrical segment pan (35) is provided as a receptacle for the cylindrical face (32) of the adjusting nut (9). The blocking slide (15) touches the cylindrical face (37) of the adjusting nut (9) in the tilted position. …<IMAGE>… |
