A cord lock desirably for a window blind assembly adapted to be releasably locked to a cord, such as a vertical cord of the window blind assembly, at alternate locations along the length of the cord. The cord lock desirably includes a first member and a second member that are hingedly connected together in any suitable manner for opening and closing the cord lock. The cord lock defines a channel for receiving the cord and includes structure for engaging the cord within the channel to releasably lock the cord lock to the cord when the cord lock is in a closed position. The channel may be elongated and defined by the second member, and the cord engaging structure may be integral or otherwise associated with the first member. The cord may be received within the channel when the cord lock is in a closed position to lock the cord lock to the cord and desirably also to substantially enclose the channel so as to define a passage with two open ends. At least a portion of the channel may be enclosed to retain the cord within the channel and permit sliding of the cord lock along the cord even when the cord lock is in the open position. A method is also provided for adjusting the length of the window blind assembly including the step of releasably locking the cord lock to the cord of the window blind assembly.
An extendible window blind assembly comprising a plurality of slats, a head rail, at least one cord interconnecting the slats, the at least one cord extending from the slats through an opening defined by the head rail and adjacent the slats for adjusting the length of the window blind assembly, and a cord lock releasably lockable to no more than one of the at least one cord at adjustable locations along the length of said no more than one cord, the cord lock adapted to be positioned and releasably locked to said no more than one cord adjacent the opening to prevent any of said no more than one cord adjacent the slats from passing though the opening to the slats.
An extendible window blind assembly comprising a plurality of slats, a head rail, at least one cord interconnecting the slats, the cord extending from the slats through an opening defined by the head rail and adjacent the slats for adjusting the length of the window blind assembly, and a cord lock releasably lockable to the cord at adjustable locations along the length of the cord, the cord lock adapted to be positioned and releasably locked to the cord adjacent the opening to prevent any of the cord adjacent the slats from passing though the opening to the slats;
An extendible window blind assembly comprising a plurality of slats, a head rail, at least one cord interconnecting the slats, the cord extending from the slats through an opening defined by the head rail and adjacent the slats for adjusting the length of the window blind assembly, and a cord lock releasably lockable to the cord at adjustable locations along the length of the cord, the cord lock adapted to be positioned and releasably locked to the cord adjacent the opening to prevent any of the cord adjacent the slats from passing though the opening to the slats;
A method for adjusting the length of an extendible window blind assembly comprising a plurality of slats, a head rail, at least one cord interconnecting the slats and extending from the slats through an opening defined by the head rail and adjacent the slats for adjusting the length of the window blind, the method comprising the step of releasably locking a cord lock to no more than one of the at least one cord adjacent the opening to prevent a portion of said no more than one cord from passing through the opening.
A method for adjusting the length of an extendible window blind assembly comprising a plurality of slats, a head rail, at least one cord interconnecting the slats and extending from the slats through an opening defined by the head rail and adjacent the slats for adjusting the length of the window blind, the method comprising the steps of releasably unlocking a cord lock engaged with no more than one of the at least one cord, sliding the cord lock along the length of said no more than one cord adjacent the opening, and releasably locking the cord lock to said no more than one cord adjacent the opening to prevent a portion of said no more than one the cord from passing through the opening.
An extendible assembly for positioning adjacent a window comprising an extendible portion, a head rail, at least one vertical cord associated with the extendible portion and extending through an opening defined by the head rail for adjusting the length of the extendible portion, and a cord lock releasably lockable to no more than one of the at least one cord at adjustable locations along the length of said no more than one cord, the cord lock adapted to be positioned and releasably locked to said no more than one cord adjacent the opening to prevent any of said no more than one cord adjacent the extendible portion from passing though the opening.
The extendible assembly of claim wherein the first and second members including locking structure for releasably locking the first and second members together when the cord lock is in the closed position.
An extendible assembly for positioning adjacent a window comprising an extendible portion, a head rail, at least one vertical cord associated with the extendible portion and extending through an opening defined by the head rail for adjusting the length of the extendible portion, and a cord lock releasably lockable to the cord at adjustable locations along the length of the cord, the cord lock adapted to be positioned and releasably locked to the cord adjacent the opening to prevent any of the cord adjacent the extendible portion from passing though the opening;
An extendible assembly for positioning adjacent a window comprising an extendible portion, a head rail, at least one vertical cord associated with the extendible portion and extending through an opening defined by the head rail for adjusting the length of the extendible portion, and a cord lock releasably lockable to the cord at adjustable locations along the length of the cord, the cord lock adapted to be positioned and releasably locked to the cord adjacent the opening to prevent any of the cord adjacent the extendible portion from passing though the opening;
