Abstract: A ladder tape device for a venetian blind includes a U-shaped fixing base fixed in a head rail of the venetian blind, a ladder tape retainer with opposite ends placed on corresponding two side-panels of the fixing base, a plurality of ladder tapes with a top end of each ladder tape passing through the fixing base and being wound on the ladder tape retainer, and a limiting cover buckled on the top end of the fixing base, an inner wall of the limiting cover and an outer wall of the top end of the ladder tape retainer are separated by a predetermined distance to form a ladder tape limiting space.
Abstract: A window covering apparatus is disclosed, along with a method of using the same. The apparatus may include an upper board component and a lower board component, which are releasably held by central mounts. The upper board and lower board components can be arranged in a fully open shutter state, a half open shutter state, or a fully closed shutter state. The central mounts are positioned near flush to one or more outside or surrounding window surfaces in order to block light transmission. In one embodiment, the upper board and/or the lower board component may incorporate decorative elements and a gapless seam between the upper board and lower board components.
Abstract: A window blind includes a headrail, a covering assembly including a plurality of slats and a bottom rail, a lifting mechanism including a driving module and a lift cord assembly operably connected to the driving module, a tilt mechanism adapted to drive the slats to rotate, and an auxiliary unit provided between the tilt mechanism and the lifting mechanism. The lift cord assembly is connected to the bottom rail for expanding or folding the covering assembly. The covering assembly is in a first state when each and every one of the slats is substantially parallel to each other and correspondingly rotatable by the tilt mechanism, and is in a second state otherwise. When the covering assembly is in the second state, the auxiliary unit is drivable by the tilt mechanism to make the lifting mechanism further release the lift cord assembly, changing the covering assembly into the first state again.
Abstract: A roll-up door with fall protection preferably includes a door web, a pair of guide tracks, a pair of lower track brackets, a plurality of upper track brackets and a door web roller. The door web includes a plurality of screen web panels and wind bars. Opposing ends of the door web are retained in the pair of guide tracks. A first wind bar is arraigned to be 42 inches off a floor to meet OSHA fall protection standards. The door web includes at least two upper wind bars above the first wind bar and at least one lower wind bar below the first wind bar. The pair of guide tracks are secured to a wall with the pair of lower track brackets and the plurality of upper track brackets. A top of the pair of lower track brackets are located at least 42 inches above the floor.
