Pivot assembly of a swing window in the form of a pivotable window sash bounded by a stationary window frame. The assembly includes a pivot bearing formed as a socket for permanent location within a bore defined by the sash. A pivot pin connected to the frame is formed with a stop which when the pin is received in the bearing is designed to be lockingly engaged by a locking device supportable in the pivot bearing. In this way only a pivoting motion of the pin relative to the pivot bearing is permitted. This support of the locking device in the bearing occurs in a plane within both an adjacent side face of the sash and an adjacent end face of the bearing. Moreover, the device is directly actuable into and out of the locking engagement by axial displacement thereof via an adjacent opening in the side face of the sash. |
