20090188634 | CORD LOCK WITH IMPROVED WEAR SURFACE FOR AN ARCHITECTURAL COVERING - A cord guide system for extending the life of cords in a covering for an architectural opening provides long wear surfaces made of metal or ceramic which can be retrofitted into existing cord lock systems or molded into the system. The invention provides such long wear surfaces that can be used with different cord drive systems each of which permit an operator of a covering to manipulate the covering between extended and retracted positions while locking the covering in any position between fully extended and fully retracted. Cord guide surfaces are preferably made of metal or ceramic which are harder than conventional base materials used in cord lock systems and further have higher melting temperatures than either the base material for the cord lock system or the polyester cords conventionally used in coverings for architectural openings. In this manner, wear of the cord lock itself is minimized which in turn minimizes the wear of the lift cords and extends the life thereof. | 07-30-2009 |
20100206495 | Roman Curtain Device - A Roman curtain device has an inner layer, an outer layer and multiple bridging pieces attached between the inner layer and the outer layer. Each of the multiple bridging pieces has multiple through holes to allow two drawing strings from a clutching device on an upper rail penetrating the aligning through holes on different multiple bridging pieces to pull up the curtain. Thereby, the Roman curtain device has the drawing strings covered inside to avoid danger caused by exposure of the drawing strings. | 08-19-2010 |
20100282421 | WINDOW BLIND ASSEMBLY WITH A RELEASEABLE CURTAIN-DRAWING MECHANISM - A window blind assembly includes a top rail, a drawable curtain, and a releasable curtain-drawing mechanism. The drawable curtain has an upper section hung from the top rail, and a lower section extending downwardly from the upper section. The releasable curtain-drawing mechanism includes a pull cord for drawing up and lowering the drawable curtain, and at least one connecting unit for connecting releasably the pull cord to the lower section of the drawable curtain. The connecting unit includes a first engaging component connected to the pull cord, a second engaging component connected to the lower section of the drawable curtain, and an engaging mechanism disposed on the first and second engaging components for providing an engagement force therebetween to interconnect releasably the first and second engaging components. | 11-11-2010 |
20110146923 | String curtain - The string curtain has a hanging rack, multiple strings, multiple beads. The hanging rack has multiple hanging holes. The strings are hung on the hanging rack, and each string has a hanging head and a mounting head. The hanging head is mounted around the top end of the string, and mounted through one of the hanging holes, and protrudes a fastening tab toward the bottom end of the string, and fastened on the hanging hole of the hanging rack. The mounting head is mounted around the bottom end of the string. The beads are mounted slidably on the strings from the mounting head. Each bead has an inner diameter smaller than the outer diameter of the string for securely mounted around the string, and may be relocated a new pattern easily. | 06-23-2011 |
20130092330 | LOW FRICTION CURTAIN DOOR STRIPPING - An industrial traffic curtain can be formed of a plurality of overlapping strips suspended contiguously to each other from a hanger fixed adjacent to a top margin of the opening. Each strip is of a flexible transparent material of substantially uniform longitudinal character having a lateral cross-section defined by an alternating series of thicker portions separated from each other by thinner portions, the thicker and thinner portions having approximately the same width, the thinner and thicker portions being united by narrower tapered regions of changing thickness. The traffic curtain thus formed exhibits a surprisingly lower electrostatic attraction between the strips so that the resistance to separation from each other as goods and transporting vehicles attempt to pass through the curtain is much lower than prior art curtains. | 04-18-2013 |
