DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a curtain assembly in accordance with the present invention comprises a head box (10), a distributor (20) disposed under the head box (10), a telescopic shutter (30) disposed under the distributor (20) and a lower bar (40) disposed under the telescopic shutter (30).


The head box (10) has a chamber (11) longitudinally defined therein and two through holes (12) defined in a bottom of the chamber (11). A first control set (13) and a second control set (14) are respectively received in the chamber (11) mounted to two opposite sides of the head box (10).


The distributor (20) is disposed under the head box (10) and connected to a top portion of the telescopic shutter (30). The distributor (20) is reciprocally and vertically moved to collect/stretch the telescopic shutter (30) due to the first control set (13).


The telescopic shutter (30) has a lower portion connected to the lower bar (40). The second control set (14) drives the lower bar (40) to collect/stretch the telescopic shutter (30). A series of passages is formed in the telescopic shutter (30) when the telescopic shutter (30) is stretched.


The first control set (13) has a first shaft (131) rotatably received in the chamber (11) in the head box (10). A first cord (132) and a second cord (133) respectively have a first end wound on two opposite ends of the first shaft (131). The first cord (132) and the second cord (133) respectively have a second end extending through a corresponding one of the two through holes (12) and fixed on the distributor (20). A first rope (135) has a first end wound on the first shaft (131) and a second end connected to a first driver (134) that is mounted in the head box (10). The first driver (134) automatically and reciprocally drives the first rope. (135) for rotating the first shaft (131) to operate the distributor (20).


The second control set (14) has a second shaft (141) rotatably received in the chamber (11) in the head box (10). A third cord (142) and a fourth cord (143) respectively have a first end wound on two opposite ends of the second shaft (141). The third cord (142) and the fourth cord (143) respectively have a second end extending through a corresponding one of the two through holes (12) and fixed on the lower bar (40). A second rope (145) has a first end wound on the second shaft (141) and a second end connected to a second driver (144) that is mounted in the head box (10) opposite to the first driver (134). The second driver (144) automatically and reciprocally drives the second rope (145) for rotating the second shaft (141) and operating the lower bar (40) to collect/stretch the telescopic shutter (30).


When stretching the telescopic shutter (30), the lower bar (40) is downward forced to pull the telescopic shutter (30). The third cord (142) and the fourth cord (143) is downward pulled to rotate the second shaft (141) and the second rope (145) is wound on the second shaft (141). When collecting the telescopic shutter (30), the lower bar (40) is upwardly forced to push the telescopic shutter (30). The second rope (145) is pulled into the second driver (144) and rotating the second shaft (141) to wind the third cord (142) and the fourth cord (143).


With reference to FIG. 1, the curtain assembly in accordance with the present invention is fully collected such that the head box (10), the distributor (20), the telescopic shutter (30) and the lower box (40) is adjacent to one another.


With reference to FIG. 4 that shows a full-shutting condition of the curtain assembly in accordance with the present invention, the second control set (14) changes a length of the third cord (142) and the fourth cord (143) to stretch the telescopic shutter (30) when the user downward forces the lower bar (40). The user stops to force the lower bar (40) when the telescopic shutter (30) stretches to a suitable length.


With reference to FIG. 5 that shows a semi-shutting condition of the curtain assembly in accordance with the present invention, the first control set (13) changes a length of the first cord (132) and the second cord (133) to collect a top portion of the telescopic shutter (30) and form a space between the distributor (20) and the head box (10) when the user downward forces the distributor (20). The operate mode of the first control set (13) is the same as that of the second control set (14).


In the semi-shutting condition, the user can see through the curtain assembly via the space between the distributor (20) and the head box (10), and the lower portion of the telescopic shutter (30) still provides a shutting effect. In addition, the space between the distributor (20) and the head box (10) provides a ventilating effect when the present invention is used as a door of a dressing room.


With reference to FIGS. 6 and 7, the curtain assembly in accordance with the present invention further comprises an auxiliary rod (50) for user to easily downward pull the lower bar (40) and the distributor (20) when the curtain assembly is disposed on a high place. The auxiliary rod (50) is L-shaped and forms with an insertion (51) on an upper end thereof. A first bore (21) and a second bore (44) are respectively laterally defined in the distributor (20) and the lower bar (40) for receiving the insertion (51).


Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
