发明名称 SAFETY DEVICE FOR QUICKLY RELEASING CONTROL ROPES OF ROMAN SHADES
摘要 A safety device for Roman shades includes multiple loop members connected to each of the folding lines on the shade and multiple restriction members are connected to multiple loop members. Each restriction member includes multiple extensions which spirally wrap to each other so as to define an opening therebetween. Multiple engaging members are connected to the loop members located at a lower end of the shade. Multiple control ropes each have a top end connected to the top box of the Roman shade and the lower end of each control rope extends through the openings of the restriction members and is connected to a collar. The collars can be disengaged from the engaging members. When the control ropes are pulled laterally, the collars are disengaged from the engaging members and the control ropes are disengaged from the extensions of the restriction members.
