A swivel fitting for an outwardly opening window, with a device for moving the casement frame between the closed position and the open position, for example in the form of a hand crank, with position-fixing arm driven by the crank and with an operating handle on one frame member of the stationary frame, in order to fix the casement frame in the closed position. At least one locking plate is included on the casement frame which co-operates with a locking element on a drive rod operable by the handle. When the window is in the closed position, a locking projection of the locking plate protrudes into a groove in the stationary frame so that the closing movement of the window may be supported relatively early by actuation of the handle and to ensure high security against break-in.

A window comprising a casement frame pivoted to a stationary frame, said stationary frame consisting of stationary frame members which extend along a rectangle defining a frame plane, with a frame exterior parallel to the plane of the stationary frame and a frame interior lying opposite to the frame

A window comprising a casement frame pivoted to a stationary frame, said stationary frame consisting of stationary frame members which extend along a rectangle defining a frame plane, with a frame exterior parallel to the plane of the stationary frame and a frame interior lying opposite to the frame exterior, said casement frame consisting of a casement frame members which extend along a rectangle defining a casement plane, with a casement exterior parallel to the casement plane and with a casement interior lying opposite to the casement exterior; said window further comprising pivot bearing means which pivotably connect a first stationary frame member of the stationary frame with a first casement frame member, said first casement frame member being parallel to said first stationary frame member, for the pivoting movement of the casement frame in relation to the stationary frame between a closed position and an open position of the casement frame about a pivot axis, parallel to the first stationary frame member, in the region of the frame outer face of the stationary frame, where, in the closed position of the casement frame, the frame exterior has the same orientation as the casement exterior and where the opening movement of the casement frame takes place from the closed position into the open position in the direction from the frame interior to the frame exterior; a device for the movement of the casement frame between the closed position and the open position; drive rod means which are fitted on a second stationary frame member lying opposite to the first stationary frame member, for movement along the second stationary frame member; an operating handle on the second stationary frame member, on the frame interior, said handle being coupled with the drive rod means for the movement of the drive rod means between a release position and a locking position; at least one locking element fitted on the drive rod means; and at least one locking plate, which is fitted on a second casement frame member of the casement frame lying opposite to the first casement frame member and upon which said at least one locking element acts, wherein the locking plate is formed with a locking protuberance protruding over the casement interior, which, in the closed position of the casement frame, engages in a groove of the second stationary frame member, with, at most, a slight spacing between a locking protuberance side face substantially perpendicular to the casement plane and substantially parallel to the second casement frame member and a side face of the groove and with a blocking face, extending substantially perpendicularly of the side face, on a side of the locking protuberance lying opposite to the side face, with which blocking face the locking element engages in the closed position of the casement frame and, at the same time, in the locking position of the drive rod means.
