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.

Description

    FIELD OF THE INVENTION
  • The 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 INVENTION
  • There 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 FIGS. 1 and 2, the window covering fabric 10, made by weaving or knitting, has light-penetrating portions 11 formed with a plurality of pores 111 and opaque portions 12 without pores that are spaced from each other alternately. The window covering fabric 10 can be formed and installed in an annular double-layer and overlapped fashion with a front side and a back side that are moveable through a lift cord 13. Or as shown in FIG. 3, a window fabric consists of a first flexible shade 10 a and a second flexible shade 10 b that have respectively light penetrating portions 11 a and 11 b, and opaque portions 12 a and 12 b, and a transverse-moving means 21 installed on an upper elongated support 20. Through the lift cord 13 or the transverse-moving means 21, the first flexible shade 10 a or the second flexible shade 10 b can be moved to make the light penetrating portions 11, 11 a and 11 b and the opaque portions 12, 12 a and 12 b overlapped or staggered with each other to adjust indoor lighting or dark condition. However, the window covering fabric 10 formed by weaving or knitting as previously discussed still has drawbacks during production, notably:
  • 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 INVENTION
  • The 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.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a conventional window covering fabric made by weaving or knitting.
  • FIG. 2 is a front view according to FIG. 1.
  • FIG. 3 is a perspective view of another conventional window covering fabric made by weaving or knitting.
  • FIG. 4 is a front view of the window covering fabric of the invention.
  • FIG. 5 is a perspective view of the window covering fabric of the invention at the condition in use.
  • FIG. 6 is a front view of the window covering fabric of the invention at the condition in use.
  • FIG. 7 is a front view of the window covering fabric of the invention formed in a transverse-moving zebra-stripe shade.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Please refer to FIG. 4, the window covering fabric according to the invention mainly includes a flexible shade 30 which has light penetrating portions 31 with a plurality of pores 311 formed thereon by drilling or punching in spaced columns or rows, and opaque portions 32 with no pores formed thereon. The light penetrating portions 31 and the opaque portions 32 are spaced from each other alternately.
  • 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.
  • Also referring to FIG. 5, when the window covering fabric of the invention is in practical use, it can be formed in an annular manner with a front shade 300 and a back shade 301 overlapping with each other to become a double-layer zebra-stripe shade. Through a manual-driven lift cord 33 the light penetrating portions 31 and opaque portions 32 of the front shade 300 and back shade 301 can be overlapped or staggered with each other to adjust indoor lighting or dark condition.
  • Refer to FIGS. 5 and 6 for an embodiment at the condition in use. The pores 311 of the light penetrating portions 31 are formed in spaced columns or rows in a linear or random fashion. When in use, the lift cord 33 is moved to make the light penetrating portion 31 and opaque portions 32 of the front and back shades 300 and 301 overlapped or staggered with each other to adjust the indoor lighting or dark condition.
  • Refer to FIG. 7 for another embodiment of the invention. The window covering fabric of the invention may also be divided into a first flexible shade 30 a and a second flexible shade 30 b that have respectively light penetrating portions 31 a and 31 b with a plurality of pores 311 a and 311 b formed thereon by drilling or punching and opaque portions 32 a and 32 b with no pores formed thereon. The pores 311 a and 311 b formed on the first and second flexible shades 30 a and 30 b may be spaced from each other in columns or rows in a linear or a random fashion. The window covering fabric thus made is installed on an upper elongated support 40 which has a transverse-moving means 41 located thereon. One end of the first flexible shade 30 a is hold pivotally to the transverse-moving means 41 and coupled with a transmission means (not shown in the drawings) at one end of the upper elongated support 40 through a shade lift cord assembly 42 so that a transverse movement of the first flexible shade 30 a can be formed to adjust the overlapping size of the light penetrating portions 31 a and 31 b and the opaque portions 32 a and 32 b of the first and second flexible shades 30 a and 30 b, thus lighting and dark condition can be adjusted as desired.
