Window Covering

摘要

A window covering includes a liner attached to a first rail and window covering material attached to the first rail and the liner such that the window covering material is moveable from a retracted position to an extended position when the liner is moved from its retracted position to its extended position. The window covering material can be configured to define a first number of folds when the window covering material is moved to the retracted position of the window covering material. The liner can be configured to define a second number of folds when the liner is moved to the retracted position of the liner. The second number of folds can be a number of folds that is at least 50% larger than the first number of folds formed in the window covering material when it is moved to its retracted position.

1. A window covering comprising:
a first rail; a liner attached to the first rail such that the liner is moveable from an extended position to a retracted position; window covering material attached to at least one of the first rail and the liner such that the window covering material is moveable from an extended position to a retracted position when the liner is moved from the retracted position of the liner to the extended position of the liner, the liner defining an unfolded and unpleated face of material facing away from the window covering material when the window covering material is in the extended position of the window covering material and the liner is in the extended position of the liner; the window covering material being attached to the liner such that the window covering material forms a first number of folds when the window covering material is moved from the extended position of the window covering material to the retracted position of the window covering material; and the liner being attached to at least one moveable cord extending from the first rail such that the liner forms a second number of folds when the liner is moved from the extended position of the liner to the retracted position of the liner, the second number of folds being a number of folds that is at least 50% larger than the first number of folds.
