<p>The object of the present invention is an end of run device for winding shafts of blinds that can be used for a wide range of blinds regardless of their length, as well as having a high breaking strength as a helical cylindrical pinion must only engage an endless gear, so that its lifetime measured in number of cycles resisting fatigue is very high, as well as having a special construction of the helical cylindrical pinion formed by two parts, as well as of the assembly meant to determine the end of run, which has a counter for the number of turns made by the blinds shaft.</p> |
