Two-way elevation curtain structure
Abstract
The present invention provides a two-way elevating curtain
structure, which uses a fixed curtain rod with several pull strings
to assemble the cord fabric. A control structure is used to elevate
the curtains up and down. The control structure includes a
first/second roll-up cord shaft, which is placed on the fixed
curtain rod to help the first/second controlling components on both
sides of the fixed curtain rod operate the first/second roll-up
cord shaft independently. The curtain is made to elevate more
smoothly.

Description
RELATED U.S. APPLICATIONS
[0001] Not applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not applicable.
REFERENCE TO MICROFICHE APPENDIX
[0003] Not applicable.
FIELD OF THE INVENTION
[0004] The present invention relates generally to a two-way
elevating curtain structure, and more particularly to a two-way
elevating curtain structure that works smoother and controls more
stably.
BACKGROUND OF THE INVENTION
[0005] The conventional blind closes or opens like a curtain for
sun or shade. The blind usually starts from the bottom. The
sunlight reflects into the house in different angles depending on
the time and outdoor objects; therefore, to shade the sunlight at
certain angles, it must lower most of the curtain to create shade,
which may cause the indoor and outdoor air to fail to circulate.
Although the lighter sunlight is stopped from coming into the
house, poor air circulation and insufficient light is created in
the house.
[0006] To solve the disadvantages created from the conventional
blind mentioned above, the industry developed a structure that
works in two directions. In addition to closing and opening the
blind up and down from the bottom, the top of the curtain can also
come down to the bottom. The bottom can also be drawn up to the
fixed curtain rod. All positions of the curtain (not just from the
bottom of the curtain) are controlled going up and down, keeping
out the sunlight that is at different angles without stopping the
circulation and natural outdoor sunlight. This improved curtain can
address the disadvantages of the conventional curtain. To control
the bottom or top of the blind to go up and down, the instrument
used still has the disadvantages of interference and disruptive
movement, therefore, it is necessary to improve the structure.
[0007] Thus, to overcome the aforementioned problems of the prior
art, it would be an advancement in the art to provide an improved
structure that can significantly improve the efficacy.
[0008] To this end, the inventor has provided the present invention
of practicability after deliberate design and evaluation based on
years of experience in the production, development and design of
related products.
BRIEF SUMMARY OF THE INVENTION
[0009] The installation of the control structure 50 uses the
first/second roll-up cord shaft 51 52 to operate the bottom 43 and
top 41 of the cord fabric to go up and down independently.
Therefore, during the operation, it will not be stuck because of
the interference. Also, the first/second roll-up cord shaft 51 52
are wrapped by the pull strings 11 12 13 14; therefore, the
wrapping movement is more stable because of the support of the
first/second roll-up cord shaft 51 52, which makes the operation of
the two-way curtain more smooth and stable.
[0010] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0018] The features and the advantages of the present invention
will be more readily understood upon a thoughtful deliberation of
the following detailed description of a preferred embodiment of the
present invention with reference to the accompanying drawings.
[0019] As shown in FIGS. 1.about.2, there is a preferred embodiment
of the present invention.
[0020] The invention includes a fixed curtain rod 10, which uses
the pull strings 11 12 13 14 of the first/second controlling
component 20 30 on both sides, and which moves the cord fabric 40
up and down (same as the conventional components, therefore, it is
not stated here in detail). The improved feature of the present
invention is the control structure 50, which includes the
first/second roll-up cord shaft 51 52 that is placed on the shaft
10 inside the fixed curtain rod 10. One end of the first/second
roll-up cord shaft 51 52 is made to connect to the first/second
controlling components 20 30, so that when the controlling cords 21
31 of the first/second controlling components 20 30 are pulled
down, it drives the controlled component 20 30 to the first/second
roll-up cord shaft 51 52 in the clockwise and counterclockwise
directions. Moreover, the first roll-up cord shaft 51 is wrapped by
the pull strings 11 12, and one end of the pull strings 11 12 go
through the fixed curtain rod 10 and through the top 41 of the cord
fabric 40. The cloth cover 42 that is connected to the bottom 43,
and the second roll-up cord shaft 52 is wrapped around by the pull
strings 13 14. One end of the pull strings 13 14 goes through the
fixed curtain rod 10 and is secured to the top 41 of the cord
fabric 40.
[0021] As shown in FIGS. 2 and 3, when the bottom 43 of the cord
fabric 40 must go up to close the cloth cover 42, the controlling
cord 21 of the first control component 20 is pulled down to move
the pull strings 11 12 of the first roll-up cord shaft 51 up and
pull the bottom 43 up to close the cloth cover 42.
[0022] As shown in FIGS. 2 and 4, when the top 41 of the cord
fabric 40 must be pulled down to the bottom 43, the controlling
cord 31 of the second control component 30 is pulled down to move
the pull strings 13 14 of the second roll-up cord shaft 52 down,
and pull the top 41 down to the cloth cover 42.
[0023] As shown in FIG. 5, the first/second controlling component
20 30 can be placed on both sides of the surface of the fixed
curtain rod 10 (the first control component 20 is disclosed here
for description), so that the first/second controlling component 20
30 is placed on the surface of the fixed curtain rod 10 in
90-degree angle. The component 20 30 uses one end of the
first/second roll-up cord shaft 51 52 to connect to the bevel gear
511 and locks in with the bevel gear 201 of the first/second
controlling components 20 30. The first and second controlling
components would now not be unable to use because of the wall, and
the assembly is made easy and convenient to operate.
[0024] As shown in FIG. 6, the present invention is also applicable
to a Roman curtain 60.
[0025] As shown in FIG. 7, when the width of the cord fabric 40 is
larger, a third set of pull strings 15 16 can also be added to the
first/second roll-up cord shaft 51 52, and connected to the top 41
of the cord fabric 40, cloth cover 42 and bottom 43 to make the
opening and closing operation more stable.
