Description
FIELD OF THE INVENTION
[0001] The present invention relates to a curtain assembly, and
more particularly, to a curtain assembly having tube units
connected thereon and control ropes are protected within the
tubes.
BACKGROUND OF THE INVENTION
[0002] A conventional curtain assembly generally includes a top box
and the curtain is connected to the lower end of the top box. The
curtain includes multiple sections separated by transverse passages
in which rods are inserted. A plurality of rings are fixed to the
curtain where the passages are located and control ropes have top
ends connected with the scrolling mechanism in the top box and the
lower ends of the control ropes extend through the rings and
finally fixed to the rings located at the lower end of the curtain.
When the user operates the control ropes to lift the curtain, the
control ropes lift the fixed rings upward and the curtain is
collected sections by sections which are overlapped to each other.
However, the control ropes do not have any protection means and are
exposed to the children so that the control ropes may trap the
children who are playing the control ropes. Besides, the control
ropes pass through the rings and are fixed only to the rings
located at the lower end of the curtain, so that the control ropes
tend to be worn out with the rings.
[0003] The present invention intends to provide a tube unit
connected to the curtain assembly and the control ropes are located
within the tubes of the tube unit, so that the control ropes are
protected.
SUMMARY OF THE INVENTION
[0004] The present invention relates to a curtain assembly which
comprises a top box and a curtain is connected to the top box.
Multiple movable rings connected to the curtain and located in
rows. Multiple fixed rings are fixed to a lower end of the curtain
and located in align with the movable rings. A plurality of tube
units each have a fixed tube and multiple movable tubes. The fixed
tube includes a first passage defined therethrough, a first flange
and a first insertion end are located at two ends of the fixed
tube. Each of the movable tubes has a second passage defined
therethrough. A second flange and a second insertion end are
located at two ends of each of the movable tubes. The fixed tubes
extend through the fixed rings and the first flanges are supported
on the fixed rings. The first insertion end of each of the fixed
tubes is fixed to the fixed ring corresponding thereto. The movable
tubes extend through the movable rings and the second flanges are
supported on the movable rings corresponding thereto. Multiple
control ropes extend from the top box and extend through the
movable tubes and the fixed tubes.
[0005] The primary object of the present invention is to provide a
curtain assembly wherein the control ropes are protected within the
movable and fixed tubes.
[0006] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] Referring to FIGS. 1 to 7, the curtain assembly 20 of the
present invention comprises a top box 21 in which a scrolling
mechanism is received, and a curtain 22 is connected to the top box
21. The curtain 22 includes multiple sections separated by
transverse passages in which rods are inserted. Multiple movable
rings 220 are connected to the curtain 22 and located in rows.
Multiple fixed rings 221 are fixed to a lower end of the curtain 22
and located in align with the movable rings 220. The movable rings
220 and the fixed rings 221 are located at the transverse
passages.
[0015] A plurality of tube units 10 are connected to the curtain 22
and each tube unit 10 has a fixed tube 11 and multiple movable
tubes 12. The fixed tube 11 includes a first passage 110 defined
therethrough and a flange 111 extends radially from a first end
thereof. A first insertion end 112 is located at a second end of
the fixed tube 11. Each of the movable tubes 12 has a second
passage 120 defined therethrough and a second flange 121 extends
radially from a first end thereof. A second insertion end 122 is
located at a second end of each of the movable tubes 12. The fixed
tubes 11 extend through the fixed rings 221 and the first flanges
111 are supported on the fixed rings 221. The first insertion end
112 of each of the fixed tubes 11 is fixed to the fixed ring 221
corresponding thereto. The movable tubes 12 extend through the
movable rings 220 and the second flanges 121 are supported on the
movable rings 220 corresponding thereto. The fixed tubes 11 and the
movable tubes 12 can be tapered tubes or cylindrical tubes. The
inner diameter of the movable rings 220 is smaller than the
diameter of each of the second flanges 121 of the movable tubes 12.
The inner diameter of the fixed rings 221 is smaller than the
diameter of each of the first flanges 111 of the fixed tubes 11. By
the specific arrangement, the first flanges 111 are supported on
the fixed rings 221 and the second flanges 121 are supported on the
movable rings 220.
[0016] Multiple control ropes 210 extend from the top box 21 and
extend through the movable tubes 12 and the fixed tubes 11. The
lower end of each control ropes 210 extends through the first
insertion end 112 of the fixed tube 11 and is fixed to the lower
end of the curtain 22. In other words, the control ropes 210 are
protected by the fixed and movable tubes 11, 12 so that the control
ropes 210 are not touched by the users and children.
[0017] When the curtain 22 is lifted by pulling the control ropes
210 as shown in FIG. 6, the movable tubes 12 are inserted into the
next one in sequence by inserting the second insertion end 122 of
one movable tube 12 into the second passage 120 of the next movable
tube 12. The second insertion end 122 of the lowest movable tube 12
is inserted into the first passage 110 of the fixed tube 11
corresponding thereto. Therefore, the curtain 22 is collected
sections by sections in sequence and the movable tubes 12 and the
fixed tubes 11 are inserted into each other to guide the collection
of the curtain 22. The control ropes 210 freely extend through the
fixed and movable tubes 11, 12 so that they are not worn out or
tangled.
[0018] The fixed and movable tubes 11, 12 ensure that the control
ropes 210 are well protected from being accessed by children so
that the curtain assembly is safety and reliable. The control ropes
210 are located within the fixed and movable tubes 11, 12 so that
the control ropes 210 are not worn out as mentioned in the
conventional example.
[0019] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
