Abstract:
A lift cord concealable Venetian blind lift is constructed to include a retractable tube formed of a plurality of tube bodies that slide one inside another and fastened to one end of each lift cord and moved between a received position and an extended position to control the elevation of the bottom rail. Each lift cord of the Venetian blind has one end fixedly fastened to the bottom rail, and the other end longitudinally extended through the headrail and then downwardly extended out of one end of the headrail into the inside of the retractable tube and coupled to the last tube body of the retractable tube for moving with the last tube body of the retractable tube to control the elevation of the bottom rail.
Abstract:
Wooden blind slats have a length, a width, and a thickness, whereby the wooden blind slats are made of a wooden board which is formed of a plurality of wooden slices, the wooden slices being joined together by an adhesive.
Abstract:
A control system for regulating light-shading status of a window blind assembly is disclosed to include a transmission mechanism and a driving device. The transmission mechanism includes a force receiving member having a receiving portion. The driving device has a force output member detachably connected to the receiving portion of the force receiving member. The receiving portion of the force receiving member is substantially a rod member having a coupling groove extended around a periphery near a bottom end thereof. The force output member has a receptacle connectable to the bottom end of the receiving portion of the force receiving member. The receptacle includes a spring arm having a protruding engagement portion for engaging the coupling groove of the receiving portion upon connection of the receptacle to the receiving portion of the force receiving member.
Abstract:
A safety window blind assembly formed of a headrail, a bottom rail, a plurality of slats, a blind supporting system, two lift cords, and a lift lock is disclosed to further include two cord stoppers respectively coupled to the lift cords and adapted to limit the moving distance of the lift cords relative to the lift lock and to further prevent a sudden dropping of the bottom rail upon failure of the lift lock. Each cord stopper has a center wire hole adapted to receive a part of one lift cord and two retaining grooves formed in the periphery thereof for retaining the part of the lift cord been inserted through the center wire hole.
Abstract:
A cord stopper for use in slidably and detachably connecting a lift cord of a window blind assembly includes a first portion provided with a cord hole, a second portion having a free end close to the first portion, and a cord-holding portion connected between the first portion and the second portion. The lift cord is folded up and inserted through the cord hole of the cord stopper to form a loop which is hung on the cord-holding portion of the cord stopper.
Abstract:
A lift lock for a blind is disclosed to include a casing holding a guide wheel, balls respectively received in respective sliding grooves around one side of the guide wheel, a shaft inserted through the casing and coupled to a lift rod of the blind, and a spring member sleeved onto the shaft for forcing an engagement portion of the shaft into engagement with a positioning opening of the casing. When the torque inputted into the lift rod surpassed the friction resistance between the casing and the shaft, the balls force the shaft to disengage the engagement portion from the positioning opening of the casing for enabling the lift rod to be freely rotated. When the input torque of the lift rod dropped, the spring member returns the shaft into engagement with the positioning opening of the casing to stop the lift rod in position.
Abstract:
A blind lift rod control lock includes a housing having an axle hole, a rotating member revolvably mounted in the axle hole of the housing, the rotating member having a non-circular through hole, which receives a lift rod for enabling the rotating member to be synchronously rotated with the lift rod, a reverse ratchet, and a forward ratchet, and a locking mechanism. The locking mechanism has a follower member, a first hooked portion adapted to engage the reverse ratchet, and a second hooked portion adapted to engage the forward ratchet. The follower member is selectively controlled to force the first hooked portion into engagement with the reverse ratchet or the second hooked portion into engagement with the forward ratchet.
Abstract:
A Venetian blind is constructed to include a horizontal headrail, two vertical side rails arranged in parallel at two sides below the headrail, a horizontal bottom rail spaced below the headrail and vertically movable along the length of the side rails, a plurality of slats arranged in parallel between the headrail and the bottom rail, two connecting cord members longitudinally connected to the slats and each having two ends respectively connected to the headrail and the bottom rail, and two positioning mechanisms provided between the side rails and the ends of the bottom rail and adapted to secure the ends of the bottom rail to the side rails at the desired elevation.
Abstract:
A vertical retractable blind is constructed to include a fixed headrail, a lifting rail vertically movable in horizontal below the headrail, two positioning cords adapted to support the lifting rail at the desired elevation. The positioning cords each have a first end connected to the headrail and a second end respectively extended across the lifting rail and fixedly secured to a respective fixed point outside the lifting rail to provide a tension force to the lifting rail. A retractable blind body is connected between the headrail and the lifting rail and vertically extended out/received subject to vertical movement of the lifting rail.
Abstract:
A curtain and Venetian blind arrangement is constructed to include a Venetian blind formed of a headrail, a bottom rail, a set of slats, and a lift cord set adapted for joining the headrail, the bottom rail and the slats and keeping the slats arranged between the headrail and the bottom rail, and a plurality of curtains coupled to the slats, each curtain having at least one peripheral side suspended from one slat; the at least one peripheral side of each curtain being mounted with at least one weight.
