<p>602825 A spring assembly for a roller blind. The assembly includes a stationary end and a rotatable end with a spring arrangement connected therebetween. The rotatable end includes a rotatable body which is adapted to rotate relative to a fixed body about a rotational axis. The spring assembly further includes a locking pin which is coupled to the fixed body such that it has a locked configuration in which it engages a portion of the rotatable body and prevents rotation of the rotatable body relative to the fixed body and a free configuration in which rotation of the rotatable body relative to the fixed body is permitted. The locking pin is slidably carried within a channel defined by the fixed body. The locking pin includes a pair of opposed end stop elements which are adapted to limit the movement of the locking pin within the channel and to prevent removal of the locking pin from the channel.</p> |
