ABSTRACT:
A tilt-lock device 3 for rotary tilt-wing windows and doors or the like consists of a tilt-lock plate 4 with lock-webs 14, 15 sitting upon the upright frame bar in the lower frame corner at the lock side and of a locking element 11 associated with the upright wing bar at the lock side sitting at the lower end of a swivel lashing 5. The swivel lashing 5 passes with its bearing pivot 10 through an elongated slot 17 in a U-rail 6 which serves for guidance of the connecting rod 7 . The swivel lashing 5 is releasable for a limited swivel motion at least in the tilt-open switch position and when a locking element 11 engages in a tilt-lock pocket 12 of the tilt-lock plate 4. A flexible bar spring 19 sits with two laterally spaced legs 19b, 19c interconected through a web 19a on the one hand in a mounting support 6, 17 and is clamped on the other hand with its two legs 19b and 19c at the swivel lashing 5 at a distance from the axis of its bearing pivot 10. The mounting space required for accommodation of the flexible bar spring 19 is to be better utilized or reduced but at the same time also the initial stress effect of the flexible bar spring 19 is to be improved while reducing the manifestations of wear between the reciprocally movable functional parts. For this purpose the flexible bar spring 19 is taken up in the eleongated slot 17 of the U-rail 6 and projects hereby with the longitudinal edges of its legs 19b and 19c beyond the outside of the U-rail 6. The swivel lashing 5 is provided at its back with two parallel longitudinal grooves 20a and 20b into which engage with fit the longitudinal edges of the legs 19b and 19c.
