发明名称 Cord-Securing Device for Window Shade
摘要 A cord-securing device for a window shade includes a plurality of holders, a plurality of rings, and an engaging unit. Each holder is fixed to a side of a shade and includes first and second holding members and an engaging groove formed between the first and second holding members. A cord is extended through the rings and fixed to an end of the engaging unit. The other end of the engaging unit is mounted to the side of the shade. When each ring is pulled by a radial external force, the first and second holding members deform, and the ring can disengage from the engaging groove of the holder, avoiding strangling and improving safety in use.
