A friction pivot joint for use between two components such as two arms, or an arm and a frame or sash plate, of a window stay. The joint comprises an aperture in a first of the components, an annular shoulder surrounding and projecting from the periphery of the aperture, an aperture in the second component such that the component is located about the shoulder. A self-lubricating and wear-resistant bushing interposed between the shoulder and the second component to prevent direct contact therebetween and a fixing element extends through the joint and is fixed within the aperture below the shoulder so as to apply friction creating pressure to the joint. |
