The window shutter bearing assembly consists of a bearing halfshell, mounted inside a mounting housing over the opening in its bottom, and a regulating roller with plugs joined to the bearing halfshell, so that they can rotate. Unique characteristics: The halfshell (4) consists of two identical parts with the horseshoe-shaped base (5). The parts are shifted, one with respect to the other, by 180 degrees and their connection surfaces (6) are put together. The surfaces are equipped with plugs (7), on one side, and corresponding sockets (8), on the other side. On its top surface (9), the halfshell has two symmetrical protrusions (10). At the top, they constitute an enclosure (11) for the plugs, while at the bottom, they constitute a patent opening (12). They have two external protrusions (13), which constitute leads (14) for the regulating cord. On the lateral external surfaces, it has catches (15) that slide through the opening (2) in the bottom of the mounting housing (1), together with the elements in the upper surface of the base (5). The complex rectangle base (5') does not slide through the opening (2) in the bottom of the mounting housing (1). |
