Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a window shade device, more
particularly to a double-layered window curtain.
[0003] 2. Description of the Related Art
[0004] Referring to FIG. 1, a conventional window curtain 1
includes a mounting seat 11, two or more positioning strings 12
mounted to the mounting set 11 and horizontally spaced apart from
each other, a plurality of curtain pieces 13 horizontally disposed
and connected in a side-by-side manner to the positioning strings
12, a driver 14 disposed on the mounting seat 11, and a cord 15
extending through the driver 14 and connected to one or more of the
curtain pieces 13. The cord 15 further has a connecting segment
16.
[0005] The curtain pieces 13 are pulled up and down along a
direction 10 by manipulation of the cord 15 and by cooperation of
the cord 15 with the driver 14 to adjust a shading height.
[0006] However, the conventional window curtain 1 has disadvantages
as follows:
[0007] i) It is possible for the cord 15 to wrap around a child's
neck, thereby causing strangling injury. The connecting segment 16
of the cord 15 running at the back side of the curtain pieces 13
will also cause strangling injury if a child sticks his/her head in
between the curtain pieces 13 and the connecting segment 16.
Therefore, the conventional window curtain 1 is dangerous,
particularly to children.
[0008] ii) There are many gaps between the curtain pieces 13
through which light can penetrate. Therefore, the conventional
window curtain 1 only minimally blocks light. In addition, people
are able to look through the gaps, and hence, the conventional
window curtain 1 is limited with respect to the amount of privacy
provided.
SUMMARY OF THE INVENTION
[0009] Therefore, the object of the present invention is to provide
a double-layered window curtain which is safe, and improves shading
effect and privacy.
[0010] Accordingly, a double-layered window curtain of the present
invention comprises a mounting seat, a window curtain unit, and a
cover unit.
[0011] The window curtain unit includes a curtain member mounted to
the mounting seat and that has inner and outer surfaces, a driver
disposed on the mounting seat, and a cord extending through the
driver and connected to the curtain member on the inner surface of
the curtain member.
[0012] The cover unit includes a shade cloth connected to the inner
surface of the curtain member and covering the cord.
[0013] The curtain member and the shade cloth are together folded
and unfolded by manipulation of the cord and by cooperation of the
cord with the driver.
BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Other features and advantages of the present invention will

curtain;
[0016] FIG. 2 is a perspective view of a double-layered window

[0018] FIG. 4 is a fragmentary side view of the double-layered
window curtain of the preferred embodiment in a fully unfolded
position.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] Referring to FIG. 2, a preferred embodiment of a
double-layered window curtain according to the present invention is
shown to comprise a mounting seat 21, a window curtain unit 22, and
a cover unit 23.
[0020] Referring to FIGS. 2, 3, and 4, the window curtain unit 22
includes a curtain member 221, a driver 222, and a cord 223. The
curtain member 221 is mounted to the mounting seat 21, and has
inner and outer surfaces. When the double-layered window curtain is
mounted covering a window inside a house, the outer surface of the
curtain member 221 faces into the house while the inner surface of
the curtain member 221 faces the window.
[0021] The curtain member 221 includes a plurality of horizontal
shade components 224 disposed and connected in a side-by-side
manner such that the curtain member 221 extends downwardly from the
mounting seat 21 when the curtain member 221 is unfolded, and a
plurality of guide rings 225 connected respectively to first
selected ones of the shade components 224 to be thereby spaced
apart vertically. The driver 222 is disposed on the mounting seat
21. The cord 223 extends through the driver 222 and is connected to
the curtain member 221 on the inner surface of the curtain member
221. The cord 223 has a connecting segment 226 extending through
the curtain member 221 and the guide rings 225, and a pulling
segment 227 extending downwardly from the driver 222.
[0022] In this embodiment, each of the shade components 224 of the
curtain member 221 is in the shape of a long piece, and is woven
with adjacent ones thereof to form a roman curtain. However, the
shade components 224 are not limited to such a configuration. Any
other materials and/or fabrics and/or interconnecting methods in
roman shades configurations may be used.
[0023] The cover unit 23 includes a shade cloth 231 connected to
the inner surface of the curtain member 221. One end of the shade
cloth 231 is mounted to the mounting seat 21. Spaced apart
horizontal portions of the shade cloth 231 are attached to second
selected ones of the shade components 224 of the curtain member 221
to thereby cover the connecting segment 226 of the cord 223 and the
guide rings 225 of the curtain member 221. In this embodiment, the
cover unit 23 further includes a plurality of weight components 232
attached to the shade cloth 231 and which are vertically spaced
apart from each other. In this embodiment, each of the weight
components 232 is a straight rod inserted into the shade cloth 231
such that the shade cloth 231 can be weighted down to abut against
the curtain member 221. However, the mounting, configuration, and
material of the weight components 232 may be varied, depending on
requirements. Furthermore, in some embodiments, the weight
components 232 are omitted from the configuration of the cover unit
23.
[0024] The curtain member 221 and the shade cloth 231 are together
folded and unfolded by manipulation of the cord 223 and by
cooperation of the cord 223 with the driver 222. Manipulation of
the pulling segment 227 of the cord 223 results in folding and
unfolding of the curtain member 221 and the shade cloth 231 among a
fully folded position, a partially folded position, and a fully
unfolded position.
[0025] The advantages of the present invention can be summarized as
follows:
[0026] i) The shade cloth 231 is attached to the shade components
224 of the curtain member 221 so that the shade cloth 231 covers
the connecting segment 226 of the cord 223 and the shade components
224 of the curtain member 221. As a result of this configuration,
strangling injuries or other accidents may be avoided since the
cord 223 is completely covered.
[0027] ii) The curtain member 221 and the shade cloth 231 form a
double-layered shade, which can not only effectively screen light
so that it does not penetrate gaps between the shade components 224
of the curtain member 221 but can also effectively prevent people
from looking through any gaps that may be present in the curtain
member 221.
[0028] iii) When the curtain member 221 and the shade cloth 231 are
folded as shown in FIG. 3, a cascading shape is formed due to the
presence of the weight components 232. This improves the aesthetics
of the double-layered window curtain of the present invention.
[0029] While the present invention has been described in connection
with what are considered the most practical and preferred
embodiments, it is understood that this invention is not limited to
the disclosed embodiments but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretation so as to encompass all such modifications and
equivalent arrangements.
