Rolling motors for rolling shutters, rolling grilles and similar installations are equipped with an integrated catching device, with the result that a very compact, small device is obtained by virtue of the drive, which is pushed into the drive shaft, and the connection of the drive shaft to the catching device, on the one hand, and to the end switch, on the other hand. The rolling motor or the drive acts, via the spindle and the end-side square member, on the drive shaft, which is designed as a hexagonal element and, for its part, again directly drives the catching device and, therefore, the end switch at the same time. Catching device and drive are assigned to the same sides of the drive shaft, with the result that, in the case of the rolling motors inserted under constricted conditions, a favourable possibility for maintenance is, nevertheless, achieved, quite apart from favourable mounting and demounting conditions. <IMAGE> |
