Abstract:
1. A turn-tilt window, comprising: a blind frame and a leaf, said leaf is tiltable in relation to the blind frame about a first axis and turnable in relation to the blind frame about a second axis; fittings, located between the leaf and the blind frame, that control the turning or the tilting of the leaf in relation to the blind frame, the fittings including at least one turn-tilt bearing, a rocker bearing, and a turn hinge; an electromechanical or electromagnetic functional element associated with at least one of the rocker bearing and the turn hinge in order to control the turning or the tilting of the leaf in relation to the blind frame, the functional element being controlled in a wireless or wired manner to move the at least one of the rocker bearing and the turn hinge into and out of a functional position of the at least one of the rocker bearing and the turn hinge, wherein the at least one of the rocker bearing and the turn hinge controls the turning or the tilting of the leaf relative to the blind frame when the at least one of the rocker bearing and the turn hinge is in the functional position of the at least one of the rocker bearing and the turn hinge; a control unit operably configured to control the functional element to move the at least one of the rocker bearing and the turn hinge into and out of the functional position of the at least one of the rocker bearing and the turn hinge; a rebated area disposed between the blind frame and the leaf when the leaf is in a closed position relative to the blind frame; first and second electromechanical or electromagnetic locking elements disposed in the rebated area for locking the leaf in the blind frame when said leaf is in said closed position, wherein the first electromechanical or electromagnetic locking element includes a first electromechanical component that is displaceable into a first locking position and a first spring that urges the first electromechanical component into an open position, the second electromechanical or electromagnetic locking element includes a second electromechanical component that is displaceable into a second locking position by and a second spring that urges the second electromechanical component into an open position, the control unit is operatively configured for controlling the first and second locking elements; an operating mechanism for controlling the functional element and the first and second locking elements; the operating mechanism comprising an L-shaped handle mounted on the leaf, said handle comprising wherein the handle is coupled in the wireless or wired manner to the functional element associated with the at least one of the rocker bearing and the turn hinge and is not operatively connected to the functional element or the at least one of the rocker bearing and the turn hinge by way of any mechanical linkages for opening and closing of the leaf, and wherein the handle is coupled in the wireless or wired manner to an electromechanical drive mechanism which is adapted to open and close the leaf, wherein the blind frame and the leaf do not have any connecting rods; and wherein the handle is configured for manual opening and closing of the leaf.
