Abstract: A safety window blind lift cord connector includes a mounting seat and a lift cord connecting ring. The lift cord connecting ring is provided at a lower portion with a lift cord fastening recess, the mounting seat has a retaining plate connected thereto to form a retaining space between them; and the lift cord connecting ring has a ring-shaped upper portion defining a middle mounting hole and having a gap formed at a top of the mounting hole. The lift cord connecting ring may be detachably connected to the mounting seat at the retaining space with the retaining plate outward extended through the middle mounting hole of the lift cord connecting ring. When a window blind lift cord fastened to the lift cord fastening recess is downward pulled with an excessive force, the lift cord connecting ring is automatically detached from the mounting seat via the gap, ensuring that the window blind lift cord would not injure any small child.

Abstract: A window blind comprises a headrail, a bottomrail and a plurality of slats, whereof the main body of the headrail is a approximate U-shaped channel, a plurality of strengthening ribs are longitudinally placed on the bottom of the channel, the rear wall and bottom of which are flat, the front wall is a V-shaped plate with a folded angle protruding outwards, underside of which being provided with holes to mount lift cords and tilt rod, the slat is W-shaped long slat, the bottomrail is an symmetrical flat tube with a flat bottom, two arc-shaped side walls and a top plane with a longitudinal groove. The window blind elegantly shaped can blind light effectively and with a high transverse stiffness, thus it is robust.

Abstract: A safety device for window curtains comprising a stopper safety hanger, a single wheel safety hanger and several safety clamps. When an object is caught by the curtain string, a small copper ball of the stopper safety hanger goes sideways from a copper wheel contracted by a steel spring wire making the copper wheel drop by its weight and loose the curtain string. A single wheel hanger is fitted for easy, balanced and convenient operation. Two string safety clamps automatically spring out from the two hangers by action of the spring clamp. The loosened curtain string separates the entangled object from danger, guaranteeing safe operation of the window curtains.
