The coupling mechanism has at least one coupling wheel coupled to the shaft that has a profile which is engaged with a counter-profile on the covering element. The loading of the spring element is kept substantially constant by the coupling mechanism as the spring ends are displaced substantially synchronously during the winding and unwinding about the rotational axis. | 10-22-2015 |
| 20150322711 | ROLLER SHUTTER - A roller shutter comprising a shutter moveable between a retracted position and an extended position is described.
