Claim:
A switching cabinet arrangement having a main door ( 10 ) and at least one auxiliary door ( 12 a , 12 b , 12 c , 12 d ) having a mounted on locking device ( 14 ) and an actuating mechanism that causes an actuating device to unlock the auxiliary door ( 12 a , 12 b , 12 c , 12 d ) as the main door ( 10 ) is opened, the switching cabinet arrangement comprising: the locking device ( 14 ) cooperating with a blocking mechanism acting on the actuating device and preventing the main door ( 10 ) from closing when the at least one auxiliary door ( 12 a , 12 b , 12 c , 12 d ) is open; wherein the actuating mechanism has a connecting rod arrangement ( 16 ; 16 a , 16 b ) horizontally guided on a side of a switching cabinet ( 20 a , 20 b , 20 c , 20 d ) oriented toward the main door ( 10 ), near a covering frame or the upper horizontal frame profile ( 18 ), the connecting rod arrangement ( 16 ; 16 a , 16 b ) extends from the main door ( 10 ) to the at least one auxiliary door ( 12 a , 12 b , 12 c , 12 d ) and slidable in an unlocking direction as the main door ( 10 ) is opened and is slidable in a locking direction (V) as the main door ( 10 ) is closed; and wherein an elongated blocking element ( 24 ) is positioned near the at least one auxiliary door ( 12 a , 12 b , 12 c , 12 d ) on the upper horizontal frame profile ( 18 ) of the switching cabinet ( 20 a , 20 b , 20 c , 20 d ) and is supported to pivot around a horizontal pivot axis ( 22 ) extending parallel to the connecting rod arrangement ( 16 ; 16 a , 16 b ) positioned above the horizontally guided connecting rod ( 16 , 16 a , 16 b ) so that when the auxiliary door ( 12 a , 12 b , 12 c , 12 d ) is open a force of gravity or of a spring orients the blocking element ( 24 ) to be spaced a slight distance apart from the connecting rod arrangement ( 16 ; 16 a , 16 b ), on the connecting rod arrangement ( 16 ; 16 a , 16 b ) a stop element ( 26 ) is spaced slightly apart from the blocking element ( 24 ), the stop element ( 26 ) has a vertical flank ( 28 ) oriented toward the elongated blocking element ( 24 ) so that when the connecting rod arrangement ( 16 : 16 a , 16 b ) slides toward the elongated blocking element ( 25 ) or in a locking direction (V) the stop element ( 26 ) strikes against the blocking element ( 24 ) and prevents the connecting rod arrangement ( 16 : 16 a , 16 b ) from sliding farther.
