DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




With reference to

FIGS. 2-7

, the double-layer drape


20


of the invention comprises an upper beam


21


and a window curtain


30


to be connected to the upper beam


21


. There are two sets of operating cord brake components


25


set inside the upper beam


21


to allow two operating cords


22


and


23


, which have respective functions, to be pierced through within. In addition, one end of both operating cords


22


and


23


are hanging over outside the two operating cord brake components


25


, respectively for a user to pull the operating cords


22


and


23


. Seeing that the operating cords


22


and


23


are controlled by the operating cord brake component


25


, therefore, the length of stretching the window curtain


30


can be folded upwards or dropped downwards. The other end of the operating cord


23


is a beaded device


24


.




The window curtain


30


is formed by two kinds of curtain cloths of both inner and outer layers. The outward layer is a pervious-to-light curtain


31


(e.g., lace curtain); whereas the inner layer


32


, which comprises a plurality of opaque curtains, Is connected to the pervious-to-light curtain


31


by up-and-down overlapping. In addition, the other ends of the operating cord


22


and the beaded device


24


are situated in-between the pervious-to-light curtains


31


and the inner layer


32


. The pervious-to-light curtain


31


with the shape of rectangle is connected the base of the upper beam


21


. The top of opaque curtain


32


attaches to or separates from the upper beam


21


through a self-attached mechanism


40


; other equidistant opaque curtains


32


, of which each base is movable, are sewed and connected to the pervious-to-light curtain


31


. The self-attached mechanism


40


comprises a hook silk layer


41


integrating with the upper beam


21


, besides, a nap layer


42


integrating with the top of the opaque curtain


32


.




The sewing lines


33


connecting the pervious-to-light curtain


31


and the opaque curtain


32


form two holes


34


(as shown in FIG.


4


), which allow the operating cords


22


and


23


to pierce through for forming the connection relationships with the pervious-to-light curtain


31


and the opaque curtain


32


, respectively.




The base of the opaque curtain


32


forms two connected cloths


35


(as shown in FIG.


5


), which link to an attached ring


36


, which comprises a small hole


37


and a bigger hole


38


. There is a notch


39


set in between the small hole


37


and the bigger hole


38


. A beaded device


24


of the operating rod


23


, which is placed from a bigger hole


38


into a small hole


37


to be positioned through the notch


39


, is utilized for fixing the plurality of equidistant opaque curtains


32


on the pervious-to-light curtain


31


; the end of the beaded device


24


is fixed in an attached ring


36


of the lowest opaque curtain


32


; in addition, the bigger hole


38


enables the operating cord


22


to pierce through, the end of the operating cord


22


is fixed in an attached ring


311


at the base of the pervious-to-light curtain


31


. Therefore, both pervious-to-light curtain


31


and the opaque curtains


32


are controlled by the operating cords


22


and


23


to be pulled upwards or downwards.




It is as shown in

FIG. 8

that the base of each opaque curtain


32


is inwardly lifted following the upward movement of the beaded device


24


when the operating cord


23


is pulled downwards. Not until being pulled to an appropriate position, the operating cord


23


is then positioned by the control of the operating cord brake component. The upward movement of each opaque curtain


32


is in between the positions as shown in

FIGS. 2 and 7

. The invention, therefore, enables the function of semi-opaque effect in the room.




The invention enables the operating cord


23


to be an unrestrained status for moving up and down, when a swing force is exerted on the operating cord


23


, hence, when the operating cord


23


is released, and the base of each opaque curtain


32


hangs over following the beaded device


24


downwards. The invention, therefore, enables the function of anti-dazzling effect inside the room; the movement is in between the positions as shown in

FIGS. 8 and 2

.




When the operating cord


22


is pulled, window curtain


30


can be folded upwards or dropped downwards; therefore, pulling the operating cord


22


upward enables the window curtain


30


to be folded in-between the positions as shown in

FIGS. 2 and 9

. At this time, the pervious-to-light curtain


31


and the opaque curtains


32


are folded upwards to enable the light to shine through in the room forming a completely well-lit effect.




In short, the window curtain


30


of the invention is made of two kinds of materials forming an Inner layer and an outer layer. The outer layer is a pervious-to-light curtain


31


; whereas the inner layer comprises a plurality of opaque curtains


32


overlapping up-and-down to be connected to the pervious-to-light curtain


31


. The base of each opaque curtain


32


is a moveable part, which can be folded upwards or dropped downwards through pulling the operating cord


23


by a user; therefore, when the operating cord


23


is pulled downwards, the plurality of opaque curtains


32


can be lifted and folded upwards to enable the light to shine through in the room with the anti-dazzling effect. The invention enables the operating cord


23


to be an unrestrained status for moving up and down, when a swing force is exerted on the operating cord


23


, so that the plurality of opaque curtains


32


hangs over by the gravity itself; the invention, therefore, enables the function of anti-dazzling effect inside the room. In addition, the pervious-to-light curtain


31


can be folded upwards or dropped downwards through pulling the operating cord


22


by a user; therefore, when the operating cord


22


is pulled downwards, the pervious-to-light curtain


31


and the opaque curtains


32


are simultaneously folded upwards to enable the light to shine through in the room generating the completely well-lit effect. The window curtain


30


, therefore, provides different two window curtain effects at one time for meeting the requirements of modem life functions; the draper of the invention offers the enrichment a variation in the fields of both operation and light control.




It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
