Abstract

A curtain assembly includes a curtain fabric, a upper supporting shaft, a lower supporting shaft, and a connecting cord. The connecting cord sequentially extends from a third supporting end portion along a corresponding side edge portion of the curtain fabric and repetitively pass through a first coupling hole of the upper supporting shaft to form a handle loop. The connecting cord passing through the first coupling hole further extends along a top edge portion of the curtain fabric and pass through a second coupling hole of the upper supporting shaft. The connecting cord passing through the second coupling hole further extends along a corresponding side edge portion of the curtain fabric to affixed on the lower supporting shaft. The curtain assembly is selectively operated between a shading position and a retracted position.

Claims17

Dependent claims

A curtain assembly, comprising:

a curtain fabric having a top edge portion, a bottom edge portion, and two side edge portions extending between said top edge portion and said bottom edge portion;
an upper supporting shaft coupled to said top edge portion, said upper supporting shaft having a first supporting end portion, a second supporting end portion, a first coupling hole and a second coupling hole formed on said first supporting end portion and said second supporting end portion respectively;
a lower supporting shaft coupled to said bottom edge portion of said curtain fabric, said lower supporting shaft having a third supporting end portion and a fourth supporting end portion;
and
a connecting cord having a first connecting end portion affixed to said third supporting end portion of said lower supporting shaft, and a second connecting end portion affixed to said fourth supporting end portion of said lower supporting shaft, said connecting cord sequentially extending from said third supporting end portion along one of said side edge portions of said curtain fabric and repetitively passing through said first coupling hole to form a handle loop, said connecting cord repetitively passing through said first coupling hole then further extending along said top edge portion of said curtain fabric and passing through said second coupling hole, said connecting cord passing through said second coupling hole further extending along said corresponding side edge portion of said curtain fabric and being affixed on said lower supporting shaft,
said curtain assembly being operated between a shading position and a retracted position, wherein in said shading position, said curtain fabric is fully extended between said upper supporting shaft and said lower supporting shaft, wherein in said retracted position, said handle loop is pulled and retained to pull said lower supporting shaft toward said upper supporting shaft so as to allow said curtain fabric to be retracted.

A method of assembling a curtain assembly, comprising the steps of:

(a) detachably affixing an upper supporting shaft and a lower supporting shaft to a top edge portion and a bottom edge portion of a curtain fabric respectively;
(b) detachably affixing a first connecting end portion of a connecting cord to a supporting end portion of said lower supporting shaft;
(c) extending said connecting cord along a side edge portion of said curtain fabric to repetitively pass through a first coupling hole of said upper supporting shaft to form a handle loop;
(d) extending said connecting cord along said top edge portion of said curtain fabric to pass through a second coupling hole of said upper supporting shaft;
and
(e) downwardly extending said connecting cord along a corresponding side edge portion of said curtain fabric, and affixing a second connecting end portion of said connecting cord to an opposed supporting end portion of said lower supporting shaft to form said curtain assembly.
