Abstract
A variable Roman drapery blind structure. The structure includes an upper beam, a transparent drapery blind piece, drapery blind pieces, and counterweight rods. The underside of the upper beam is fixedly fastened to the top edges of both the transparent drapery blind piece and one of the drapery blind pieces. A pull cord unit is disposed at an inner side of the upper beam to either collect or unfold said transparent drapery blind piece along with the drapery blind pieces. A variation pull cord having pieces of controlling pull cords attached thereto at one end is disposed at the other inner side of the upper beam to adjust the drapery blind pieces for variations. Except the first one, the drapery blind pieces are secured to one side of a multiple of long hollow tubes disposed on the transparent drapery blind piece. In addition, the counterweight rods can be adapted in different numbers and locations to vary the curvature and angle of the drapery blind pieces for various displays of the blind structure.
Description




BACKGROUND OF THE INVENTION




The present invention is related to a variable Roman drapery blind structure, comprising an upper beam whose underside is fixedly fastened to the top edges of both a transparent drapery blind piece and one of a plurality of drapery blind pieces. A pull cord unit is disposed at one inner side of said upper beam to either collect or unfold said transparent drapery blind piece along with said drapery blind pieces up or down. A variation pull cord having pieces of controlling pull cords attached thereto is disposed at the other inner side of said upper beam to adjust said drapery blind pieces for variations. In addition, a multiple of counterweight rods can be adapted to vary the curvature and angle of said drapery blind pieces for more various display of said blind structure thereof.

FIG. 1. A

conventional Roman drapery blind structure


10


is made up of a drapery body


11


of proper length and width, whose top edge is fixedly attached to the underside of an upper beam


12


. The drapery body


11


is unfolded downwards, and then folded back and seamed up with a seaming line


13


for each certain length, forming a plurality of equidistant long hollow holes


15


disposed from the top to the bottom edges thereof. A through rod


14


is led and located to each of said long hollow holes


15


thereof. A plurality of hanging ears


17


with through rings


16


attached thereto are properly and equidistantly fastened onto each said seaming line


13


. A pull cord


18


disposed at one inner side of said upper beam


12


is led through each through ring


16


disposed at both lateral sides of said drapery body


11


and fastened to the last ones disposed at the lower section thereof. Said pull cord


18


can be drawn to lift up said fastened through rings


16


, thus having said drapery body


11


collected upwards and folded up at each said long hollow hole


15


thereof respectively.




There are several drawbacks to such conventional Roman drapery blind structure


10


. First, it is monotonous in use when the pull cord


18


is drawn and the drapery body


11


simply collected and hanging down with multi-layer folds. Second, it lacks any variations in the display of said drapery body


11


except serving only for the use of a sunshade. Third, it is one-dimensional in function without the possibility of adding any beauty or creativity to it.




SUMMARY OF THE PRESENT INVENTION




It is, therefore, the primary purpose of the present invention to provide a variable Roman drapery blind structure, especially a variable drapery blind structure having an upper beam whose underside is fixedly fastened to the top edges of both a transparent drapery blind piece and one of a multiple of drapery blind pieces wherein, except the upwards and downwards movements of said transparent drapery blind piece via a pull cord disposed at one inner side of said upper beam, said drapery blind pieces can be adjusted in curvature and angle for various display by means of a variation pull cord disposed at the other inner side of said upper beam.




It is, therefore, the secondary purpose of the present invention to provide a variable Roman drapery blind structure wherein said drapery blind pieces can be easily adjusted and varied to present different styles and outlooks, increasing beauty and creativity to said Roman drapery blind structure thereof.




It is, therefore, the third purpose of the present invention to provide a variable Roman drapery blind structure with or without a multiple of counterweight rods wherein, depending on the amount and location of said counterweight rods adapted, said drapery blind pieces can be easily and economically adjusted into various styles and patterns for more various display of said Roman drapery blind structure thereof
