WINDOW TREATMENT HAVING AN ADJUSTABLE BOTTOM BAR
First Claim
1. A window treatment comprising:
- a headrail that is elongate along a first direction and is configured to be mounted to a structure, the headrail defining an internal cavity;
a lift mechanism that is mounted within the internal cavity;
a covering material having a top end and a bottom end spaced from the top end along a second direction that is perpendicular to the first direction, the top end of the covering material being attached to the headrail;
a bottom bar attached to the bottom end of the covering material, the bottom bar having a bar body that defines a first bar end and a second bar end that is spaced from the first bar end along a third direction, the bottom bar defining a channel that extends at least partially through the bar body along the third direction;
a sliding member moveable within the channel along the third direction, the sliding member including a member body that defines a first member end and a second member end spaced from the first member end along the third direction; and
a first lift cord and a second lift cord, each of the first and second lift cords having a first end that is operatively attached to the lift mechanism, and a respective second end that is attached to a respective one of the first and second member ends of the member body such that rotation of the lift mechanism causes the bottom bar to either move toward or away from the headrail along the second direction,wherein the first and second bar ends are configured to be moved relative to each other along the second direction from a first relative position to a second relative position whereby movement of the first and second bar ends from the first relative position to the second relative position causes the sliding member to move within the channel along the third direction to thereby maintain the first and second bar ends in the second relative position.

Abstract
A motorized window treatment can include a headrail that is configured to be mounted to a structure. A covering material can be attached to the headrail and configured to be raised and lowered by a pair of lift cords that are operatively attached to a lift mechanism. The treatment can also include a bottom bar that is attached to an opposite end of the covering material as the headrail. The bottom bar can define a channel, which can house a sliding member that is configured to move along the bottom bar and is coupled to the ends of the lift cords. By sliding along the channel, the sliding member allows the lengths of the lift cords to change with respect to one another such that when a force is applied to the bottom bar the bottom bar will move from an unleveled position to a leveled position.

20. A window treatment comprising:
-
a headrail that is elongate along a first direction and is configured to be mounted to a structure, the headrail defining an internal cavity; a lift mechanism that is mounted within the internal cavity; a covering material having a top end and a bottom end spaced from the top end along a second direction that is perpendicular to the first direction, the top end of the covering material being attached to the headrail; a bottom bar attached to the bottom end of the covering material, the bottom bar having a bar body that defines a first bar end and a second bar end that is spaced from the first bar end along a third direction, the bottom bar including opposed first and second internal sidewalls that at least partially define a channel that extends at least partially through the bar body along the third direction; a sliding member that is movable within the channel along the third direction, the sliding member including a member body, a first biasing member that protrudes from the member body and abuts the first internal sidewall, and a second biasing member that protrudes from the member body and abuts the second internal sidewall; and a first lift cord and a second lift cord, each of the first and second lift cords having a first end that is operatively attached to the lift mechanism, and a respective second end that is attached to the sliding member such that rotation of the lift mechanism causes the bottom bar to either move toward or away from the headrail along the second direction, wherein adjustment of the bottom bar from an unleveled position to a leveled position causes the sliding member to move within the channel along the third direction from a first relative position to a second relative position, and wherein friction between the first and second biasing members and the first and second internal sidewalls retains the sliding member in the second relative position to thereby retain the bottom bar in the leveled position. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method of adjusting the level of a bottom bar of a window treatment, the bottom bar defining a channel, and the window treatment comprising a sliding member movable within the channel and first and second lift cords attached to the sliding member, the method comprising:
-
applying a force to the bottom bar of the window treatment to thereby move the bottom bar from an unleveled position to a leveled position; and causing the sliding member to move within the channel from a first position to a second position to thereby maintain the bottom bar in the leveled position. - View Dependent Claims (37, 38)
