Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a curtain assembly, and
more particularly to a curtain assembly that can form a space for
user to see through the curtain assembly.
[0003] 2. Description of Related Art
[0004] Windows covering systems exist primarily to shield interior
spaces from direct sunlight and to prevent others from viewing
inside through the window.
[0005] A conventional window blinds usually comprises a seat and a
shaft pivotally mounted in the seat. The shaft has an annular
groove defined in a first end thereof. A drive axle longitudinally
and centrally extends through the shaft and connected with the
shaft for driving the shaft. A loop is received in the annular
groove in the shaft. The loop has a spiral groove defined in an
outer periphery thereof and connected to two opposite ends of the
loop. A cord has one end fixed on a second end of the shaft for
raising/lowering the slats of the window blinds. Two adjusting
cords respectively fixed to the two opposite ends of the loop. As a
result, the slats are raised/lowered when the shaft is continually
rotated to roll/release the cord, and the slats is adjusted when
the loop clamps the shaft and rotated with the shaft to roll the
two adjusting cords.
[0006] The shaft, the loop and the drive axle are concentrically
assembled to one another for raising/lowering or adjusting the
slats. However, to concentrically operate the shaft, the loop and
the drive axle for raising/lowering or adjusting is complicated for
a user.
[0007] The present invention has arisen to mitigate and/or obviate
the disadvantages of the conventional window shutter.
SUMMARY OF THE INVENTION
[0008] The main objective of the present invention is to provide an
improved curtain assembly that can form a space for user to see
through the curtain assembly
[0009] To achieve the objective, the curtain assembly in accordance
with the present invention comprises a head box having a chamber
longitudinally defined therein. A first control set and a second
control set are respectively received in two opposite sides of the
head box. A distributor is disposed under the head box and
connected to the first control set. The first control set is
operated when the distributor is vertically moved. A telescopic
shutter has a top portion connected to the distributor. The
telescopic shutter is collected/stretched when the distributor is
vertically moved. A lower bar is mounted to a lower portion of the
telescopic shutter and connected to the second control set. The
second control set is operated when the lower bar is vertically
moved to collect/stretch the telescopic shutter.
[0010] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0018] 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).
[0019] 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).
[0020] 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).
[0021] 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.
[0022] 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).
[0023] 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).
[0024] 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).
[0025] 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.
[0026] 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.
[0027] 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).
[0028] 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.
[0029] 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).
[0030] 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.
