<p>1. Window casement stay comprising a stop arm (5, 105, 205) connected by one end (7) to the fixed frame and a holding element (2, 102, 202) fixed to the leaf, the stop arm (5, 105, 205) being able to cooperate with said holding element (2, 102, 202) to immobilise the leaf in a determined open position, characterised in that the stop arm (5, 105, 205) is mounted to pivot with respect to the fixed frame along an axis oblique with respect to the perpendicular to the plan of join defined between the leaf and the fixed frame in the zone of the casement stay, the arm (5, 105, 205) being at rest substantially parallel to the plane of join, and the free end (6) of the stop arm (5, 105, 205) and said holding element (2, 102, 202) are arranged so that, the stop arm (5, 105, 205) having been previously moved away from its rest position, the opening of the leaf provokes engagement with blockage of said holding element (2, 102, 202) on the free end (6) of the stop arm (5, 105, 205) and immobilisation of the latter.</p> |
