Curtain control assembly with safety device for bead chain
A control assembly 1 for a roller blind or curtain incorporates a bead chain 3, and a rotatable bead chain seat 11 that is operatively coupled to a shaft for opening and closing the blind. A spring or otherwise elastic element 22 acts to bias a cover body 23 to hold the bead chain in engagement with the rotatable seat, up to a threshold pulling force at which the spring support gives way and releases the bead chain. This acts as a safety mechanism in case a user, such as a child, gets entangled in the bead chain and risks strangulation. The cover member is rotatable in register with the bead chain seat, via a clutch mechanism 12, which may include interlocking teeth 121, 241 and/or magnets (123, 243, fig 6). The cover member slides within a mounting space 21 of a lateral cover 2 and is guided into position by a connecting portion 211 and a shaft member 25.
