Roll-Up Control Device for Roller Shade
A roll-up control device 4 for a roller shade comprising a wheel assembly 5 comprising a wheel 51, a pull spring 52, an outer turntable 53, a shaft rod 54 and a clutch 55; and a brake assembly 6 comprising a brake shaft cover 61 fastening the shaft rod 54, a brake spring 62 sleeved on a side of the cover, a compression spring 63 expanded and compressed inside the cover, a brake sleeve 64 sleeved the side of the cover and a shaft housing 65 accommodating a damping ring 66 and clamping the brake sleeve. When a cord 56 is pilled the clutch slides towards the brake sleeve, compressing the spring, and the sleeve disengages from the shaft housing so the housing can be driven externally and the blind lowered by hand. When released the spring restores and the sleeve reengages with the housing.
