摘要： 1,014,789. Pivot assemblies. ATVIDABERGS INREDNINGAR A.B. Jan. 21, 1964 [Jan. 22, 1963], No. 2667/64. Heading E2F. A pivot assembly for pivot windows &c. comprises two circular discs 6, 7 disposed in circular blind bores 4, 5, in a light-alloy housing 3, the discs having arc-shaped recesses 15, 16, so that during the first 90 degrees of window rotation the recess 16 engages the disc 6 to prevent rotation of the disc 7 in the housing 3, then a stud 17 in the housing abuts the end of a slot 18 in the disc 6 to prevent further rotation of the disc 6 in the housing, and then during window rotation from 90 degrees up to 180 degrees the recess 15 engages the disc 7 to prevent rotation of the disc 6. The first disc 6 is adjustably clamped to a bracket 1 screwable to a window-frame, and the second disc 7 is separably attached to a bracket 2 screwable to a window sash. The discs 6, 7 each have a radial slit, the edges of which are engaged by a conical screw and nut 13, 14 received in conical bores 20 and adjustable via holes 19 in the bottom of each bore 4, 5 so as to adjust the friction between the discs and the bores.
