Abstract
A covering for an architectural opening, having a first layer with alternating relatively opaque stripes and relatively translucent stripes, and a second layer with alternation relatively opaque stripes and relatively translucent stripes. The first and second layers are positioned one behind the other, with the stripes substantially parallel. The first and second layers are movable relative to one another in a direction substantially perpendicular to the stripes. The covering also includes a series of parallel binder threads for attaching the first layer to the second layer. The binder threads run substantially perpendicular to the stripes, and thereby, one of the layers can be slid along the binder threads when moved relative to the other. The blind is preferred to be woven as a double-layer fabric.
Claims21
An architectural covering, comprising:
- a first fabric layer;
- a pulling thread which passes through the first layer to form, along the pulling thread, spaced apart, pulling thread loops about threads of the first layer;
- an end of the pulling thread being located at a side of the first layer;
- and the first layer being slidable along the pulling thread, toward the end of the pulling thread when the end of the pulling thread is pulled toward an opposite end of the pulling thread with the side of the first layer;
- a second fabric layer that is parallel and adjacent to the first layer and substantially coincident with the first layer;
- the second layer being capable of movement relative to the first layer in a direction parallel to the first layer;
- and
- a binder thread, between the layers, which connects them and extends in the direction of movement of the second layer;
- the second layer being slidable along the binder thread during the movement of the second layer relative to the first layer;
- the first and second layers having complementary patterns.
