Abstract: A safety buckle of a curtain comprises a curtain body and an upper beam; an auto slide-stop installed within the upper beam for controlling the curtain body to a predetermined position; and a control rope set having a first end and a second end which are at opposite sides. The first end is a rope and the second end. The safety buckle comprises a male pin having a body portion and a guide end. The body portion is positioned at a bottom of the guide end and is connected to a distal end of the rope. A female pin is firmly secured to the upper beam and has a pin seat. The pin seat is formed with a hollow guide hole. When the ropes are pulled, the male pin is separated from the female pin so that the upper beam and the ropes are in a safe state.

Abstract: A curtain assembly contains a long cloth. An upper extending portion has a plurality of parallel and equally spaced first folding portions, a plurality of first supporting portions, and a plurality of first rings. The first folding portions are seamed to be as a bag. The second folding portions are seamed to be formed with left and right bags for receiving the second supporting portions. A flexible cloth sleeve is placed between each two bags. A plurality of second rings are seamed to be between the left and right bags. A stopper is combined to the top portion and is controlled by a rope unit so as to stop the cloth at a predetermined position. When second ends of the control ropes of the rope unit move upwards, the second rings of the lower extending portions will overlap so as to form a sector area.

Abstract: A width-adjustable curtain track includes a track assembly and a connection device to link to the track assembly, which, as well as connection device, can be undrawn or folded in the axial direction, to enable a curtain cloth that is attached on the connection device to extended or folded followed the connection device. Owing to the adjustable width function of the track assembly, the invention is applicable to various window frames for adjusting to required widths to further increase the convenience of curtain usage.
