Abstract

1. Locking device for locking a slide-in unit in a slide-in compartment of an electrical switch cabinet in at least one position, which slide-in unit contains at least one switchgear adapted to be operated from outside by means of a switch handle (36) with the aid of a switch shaft (70) and at least one control means and one feedback control means and which is adapted to be guidedly inserted into the slide-in compartment, said device comprising a known rod drive mechanism (41, 38, 42) having two rods (41, 42) which are displaceable oppositely to each other by means of a shaft and which in the locking position project beyond the slide-in unit on both sides and in the unlocked position remain inside the edges of the slide-in unit, and further comprising a securing device, characterized in that the rod drive mechanism (41, 38, 42) is constructed as a rack-and-pinion mechanism comprising two racks (41, 42) and the shaft (38) is constructed as a pinion driving both racks, and that in dependence on the position of the switch shaft (70) of the switchgear the securing device secures the locking through a locking rod (60) operated by the switch shaft and adapted to be brought into engagement with one of at least one recess (78, 80) in one (42) of the racks, while the locking rod (60) itself in turn holds the switch shaft (70) in the off position when the locking device and consequently also the racks (41, 42) are situated outside predetermined positions.
