WINDOW COVERING FABRIC AND A TRANSVERSE-MOVING ZEBRA-STRIPE SHADE THEREOF
A window covering fabric and a transverse-moving zebra-stripe shade thereof includes a flexible shade with light penetrating portions located thereon that have a plurality of pores formed in spaced columns or rows by drilling or punching and opaque portions which do not have pores. The light penetrating portions and the opaque portions are spaced from each other alternately. The window covering fabric thus formed can be installed in an overlapped fashion in a front side and a back side relative to each other to become a double-layer zebra-stripe shade and is movable through a transverse-moving means to make the light penetrating portions and the opaque portions overlapped or staggered with each other to facilitate adjustment of indoor lighting or dark condition.
This application is a Divisional of co-pending application Ser. No. 12/048,308, filed on Mar. 14, 2008, and for which priority is claimed under 35 U.S.C. § 120, the entire contents of which are hereby incorporated by reference.
FIELD OF THE INVENTIONThe present invention relates to a window covering fabric and a transverse-moving zebra-stripe shade thereof and particularly to a window covering fabric to facilitate adjustment of indoor lighting and dark condition.
BACKGROUND OF THE INVENTIONThere are many different types of window covering fabric 10 on the market to make window coverings such as pleated window coverings, roman shades and the like. They mainly aim to be installed at doors and windows of houses to block sunshine and serve decorative purpose. When in use, referring to
Forming the porous light penetrating portions by weaving or knitting is a tedious and time-consuming process, and production cost is higher. Consumers do not have much incentive to purchase. To boost demand is difficult. All this hinders wider adoption of the window covering fabric.
SUMMARY OF THE INVENTIONThe present invention aims to provide a window covering fabric and a transverse-moving zebra-stripe shade thereof that has a flexible shade including light penetrating portions with a plurality of pores formed thereon and opaque portions with no pores formed thereon that are spaced from each other alternately, and can be installed in a front side and a back side relative to each other such that the light penetrating portions and the opaque portions are overlapped or staggered with each other to facilitate adjustment of indoor lighting or dark condition.
To achieve the foregoing object, the window covering fabric according to the invention mainly includes a flexible shade which has light penetrating portions with a plurality of pores formed thereon in spaced columns or rows by drilling or punching and opaque portions which do not have pores. The light penetrating portions and the opaque portions are spaced from each other alternately.
Another object of the invention is to provide a transverse-moving zebra-stripe shade made from the window covering fabric previously discussed such that it can be installed in an overlapped fashion in a front side and a back side relative to each other, and is movable through a transverse-moving means to make the light penetrating portions and the opaque portions overlapped or staggered with each other to facilitate adjustment of indoor lighting or dark condition.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
Please refer to
The flexible shade 30 may be a textile or non-woven, and the material being used may be plant fibers or polymers.
The pores 311 on the light penetrating portions 31 as shown in an embodiment of the drawing may be formed in spaced columns or rows in a linear or random fashion.

Claims
1. A transverse-moving zebra-stripe shade comprising a first flexible shade and a separate second flexible shade that have respectively light penetrating portions which have a plurality of pores formed thereon by drilling or punching in spaced columns or rows and opaque portions which do not have pores formed thereon, the light penetrating portions and the opaque portions being spaced from each other alternately; and a transverse-moving means to move the first flexible shade transversely.
2. The transverse-moving zebra-stripe shade of claim 1, wherein the pores of the first flexible shade and the second flexible shade are formed in a linear fashion.
3. The transverse-moving zebra-stripe shade of claim 1, wherein the opaque portions of the first flexible shade and the second flexible shade are formed without drilling or punching pores.
4. The transverse-moving zebra-stripe shade of claim 1, wherein the transverse-moving means moves the first flexible shade while the second shade is stationary.
