<p>1. A device for latching turn-tilt windows or doors or the like in the tilted position, the device comprising : a plate (4) disposed in the closure-side bottom frame corner of the vertical frame member and having latching webs (14, 15) ; and a latching member (11) which is associated with the closure-side upright sash member at the bottom corner and which is disposed at the bottom end of a pivoted link (5) connected at its top end by way of a bearing pin (10) to a positioning bar (7), the pivoted link engaging by way of its bearing pin through an elongate slot (17) in a faceplate (6) adapted to guide the positioning bar, said link being releasable for a limited pivoting movement relatively to the faceplate, positioning bar and plate (4) when the latching element engages in a latching pocket (12) in the plate (4), a flexible bar spring (19) which has two laterally spaced-apart legs (19b, 19c) interconnected by a web (19a) being disposed in retaining means (6, 17) and also being clamped by way of its two legs to the pivoted link at a distance from the axis of the bearing pin of such link, characterised in that the flexible bar spring (19) is received in the longitudinal slot (17) in the faceplate (6) and projects by way of the longitudinal edges of its legs (19b, 19c) beyond the outside of the faceplate (6), the pivoted link (5) is formed on its back with two parallel longitudinal grooves (20a, 20b) in which the longitudinal edges of the legs (19b, 19c) engage in a good fit, and the longitudinal slot (17) has on both its longitudinal edges (18) in the bottom longitudinal zone two bulges or widenings (18b, 18d) separated from one another by a nose (18c), the legs (19b, 19c) of the spring (19) taking up a position at a distance from such bulges or widenings in their off-load normal position.</p> |
