The invention relates to a locking device at a spagnolet mechanism ( 1 ), anchored in a door or window case ( 39 ), which mechanism comprises a central adjusting mechanism ( 2 ), from which locking rods ( 7 ) originate in mutually opposite directions, the free ends of the locking rods ( 7 ) being anchored in recesses ( 41 ) in a frame ( 40 ), a locking bolt ( 42 ) being responsible for the locking, which is pivotable around a stationary revolving spindle pin ( 44 ) by the locking rods, which locking bolt ( 42 ) via a connection link ( 43 ) with joints adjacent its ends in a locking house ( 16 ) is connected to the associated locking rod. According to the invention the locking bolt ( 42 ) is partially inserted into the locking house ( 16 ) and is anchored there by way of the revolving spindle pin ( 44 ). The locking bolt is connected in an extreme outwardly pivoted position to the connection link ( 43 ) via its first joint ( 45 ) and is pivoted into the locking house jointly with connection link, which in the locking house is connected to its second joint ( 46 ) with the corresponding locking rod end, which jointly with the adjusting mechanism ( 2 ) prevent the locking bolt ( 42 ) from pivoting back to the extreme position. In this way the unity of the coupling is secured. |
