Window covering fabric and a transverse-moving zebra-stripe shade thereof

Abstract

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.

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.
