The lock of the passive door blade of a double door according to the invention comprises a lock body (23), a latch (17) and a control wedge (18). The control wedge is arranged to linearly move to a position extended out from the lock and to a position retracted inside the lock. The lock additionally comprises a lever (20), a leading shaft (21) and a spring system (27). The lever (20) is rotatably attached (25) to the control wedge (18) by its first end and rotatably attached (24) to the leading shaft (21) by its second end. The leading shaft (21) is additionally rotatably attached (22) to the lock body (23) and the leading shaft comprises a control cam (26) being in connection with the latch (17). The lever (20) and the leading shaft (21) are arranged to transfer the force of the spring system (27) to the control wedge (18) so that the force parallel with the linear movement of the control wedge is at its largest in the extended position of the control wedge and at its smallest when the control wedge is in the retracted position inside the lock.

Le loquet d'une lame de porte passive d'une porte à deux battants selon l'invention comprend un corps de loquet (23), un verrou (17) et un coin de commande (18). Le coin de commande est ménagé de manière à se déplacer linéairement vers une position étendue en dehors du loquet et vers une position rétractée à l'intérieur du loquet. Le loquet comprend également un levier (20), une tige conductrice (21) et un système de ressort (27). Le levier (20) est relié de manière rotative (25) au coin de commande (18) par sa première extrémité et il est relié de manière rotative (24) à la tige conductrice (21) par sa seconde extrémité. La tige conductrice (21) est également reliée (22) au corps de loquet (23) et elle comprend une came de commande (26) reliée au verrou (17). Le levier (20) et la tige conductrice (21) sont disposés de manière à transférer la force du système de ressort (27) au coin de commande (21) de telle sorte que la force parallèle au mouvement linéaire du coin de commande soit la plus grande dans la position étendue du coin de commande et la plus petite lorsque le coin de commande est dans une position rétractée à l'intérieur du loquet.
