<p>The invention relates to the structural elements of protective devices for closing window, door and similar openings and can be used in electrically driven roller blinds. The technical result is that of reducing the overall dimensions, simplifying installation and maintenance, and preventing electrical connections between components during the assembly of roller blind-like products. The claimed technical result is achieved in that an electrically driven roller blind with a motor inside the shaft and with an independent power supply, said blind comprising a container with batteries and constituting a complete unit consisting of a cylindrical container combined with sliding bearings that ensure the free rotation of the external tube of the roller blind or other lifting device driven by a D.C. motor inside the shaft, is characterized in that the container, containing cylindrical batteries for supplying power to a D.C. motor inside the shaft, which sets the device in motion, is mounted inside the body of the in-shaft motor so that the container and the motor together make up a single unit with an independent power supply.</p> |
