Abstract: Swing window arrangement equipped with a child safety device and having a pair of pivot mountings (12) which are each provided with a frame fastening plate (13) which supports, about a first pivot pin (15), a first, upper pivot arm (16) and, about a second, lower pivot pin (17), a second, lower pivot arm (18), at a certain distance from each other. The child safety device is only arranged on the one pivot mounting. A first component (23) of the child safety device, which forms a weight-loaded drop bolt, is arranged axially moveable on the frame fastening plate (13). A second component (24) of the child safety device, which is provided with a stop forming hook (24a), is fastened to the lower pivot arm (18) in order to be swung together with the latter and by this means is moved inwards into and outwards from a locking engagement with the first component (23).

Abstract: The manually releasable stop device permits unimpeded swinging of the window within a limited angle of rotation between the closed and partially open window. After releasing the stop device further swinging of the window is permitted beyond the limited angle of rotation. The stop device comprises two cooperating stop members (25, 26) which are fastened to respective support members (14, 18) in the window hinge which are pivotable relative to each other. A first stop member is constituted by a stop element (26) fixedly fastened to the one support member (14), and the second stop member is constituted by a self-locking catch element (25) fastened to the other support member (18). The catch element cooperates with a positive control mechanism (26, 32, 37, 39) in the pivotal region of the window within the limited angle of rotation.

Abstract: Turnable window arrangement of the kind in which a window sash is capable of being rotated about a horizontal axis through approximately 180.degree. relative to a window frame while the pivotal axis of the sash is moved between upper and lower positions in the frame. A pivot pin is supported horizontally by the sash via a mounting on opposite sides of the upper side portion of the sash. The pivot pin is formed with a head and has a slide portion-supporting lug pivotally mounted thereon. The frame has a first guide groove with which the slide portion is slidably engaged as well as a second guide groove parallel to the first guide groove and receiving the head of the pivot pin. The frame and the sash define a relatively narrow, vertical gap in a direction transversely of the main plane of the window. The lug has a main portion freely pivotable in this gap and made of relatively thin-walled spring steel. The sash is formed with a groove for receiving the mounting supporting the pivot pin.

Abstract: 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.
