Tilt-lock device

Tilt-lock device for rotary tilt-wing windows and doors or the like, consisting of a tilt-lock plate with lock webs sitting upon an upright frame bar in a lower frame corner at a lock side, and of a locking element associated with an upright wing bar at the lock side, which sits at a lower end of a swivel lashing which is connected through a bearing pivot at its upper end with a connecting rod, whereby the swivel lashing passes with its bearing pivot through an elongated slot in a U-rail which serves for guidance of the connecting rod, and is releasable at least in a tilt-open switch-position for a limited swivel motion on a locking element engaging in a tilt-lock pocket in the tilt-lock plate relative to the U-rail, connecting road as well as tilt-lock plate, and wherein a flexible bar spring sits with two laterally spaced legs connected with one another through a web on the one hand in a mounting support and is clamped on the other hand with its two legs at the swivel lashing at a distance from the axis of its bearing pivot,

• characterized by the fact that, the flexible bar spring (19) is partially taken up in the elongated slot (17) of the U-rail (6) and protrudes with the longitudinal edges of it legs (19b and 19c) beyond the outside of the U-rail (6),
• that the swivel lashing (5) is provided at its back with two parallel longitudinal grooves (20a and 20b), into which the longitudinal edges of the legs (19b and 19c) fittingly engage, and
• that the elongated slot (17) is provided on both longitudinal edges (18) in the lower longitudinal region in each case with mutually limited enlargements (18b and 18d) separated by a lug (18c) from which the legs (19b, 19c) of the flexible bar spring (19) take up a spacing in their slack resting position.
