<p>The invention relates to a safety lock ( 1 ) for opening members ( 2 ), such as doors and windows, comprising a stop shoulder ( 3 ) arranged adjacent to the frame ( 4 ) of the door, a locking means ( 5 ) arranged adjacent to the door ( 2 ) and movable along the plane of the door, and movingly overlapping the stop shoulder ( 3 ). The locking means ( 5 ) is operable at least from the inside of the door ( 2 ), said locking means ( 5 ), having a locked position, a safety position and an open position. Said locking means ( 5 ) constitutes both lock and limitation for the opening movement of the door. The end part ( 6 ) of the locking means is, when the locking means ( 5 ) is in its safety position, movable a limited distance perpendicular to the plane of the door. The end part ( 6 ) of said locking means engages an abutment means ( 7 ) arranged adjacent to the frame ( 4 ) and thus limits the opening movement of the door. The end part ( 6 ) of the locking means is, when the locking means ( 5 ) is in its locked position, rigidly connected to the remaining part of the locking means ( 5 ) and overlaps said stop shoulder, said locking means ( 5 ), in its open position, being moved from its position overlapping said stop shoulder ( 3 ).</p> |
