[0001]The present disclosure relates to systems to operate curtains. In particular it
pertains to a method and system for operating a curtain that assists in opening a curtain in an aesthetic profile.
BACKGROUND OF THE DISCLOSURE
[0002] The background description includes information that may be useful in
understanding the present invention. It is not an admission that any of the information provided
herein is prior art or relevant to the presently claimed invention, or that any publication
specifically or implicitly referenced is prior art.
[0003] Various curtain operation devices and systems exist presently. All of them are
either AC motor based or DC brush motor based. Many of these devices are operable through an
infra-red (IR) remote. Some companies have developed Wi-Fi driver for curtains and they are
integrating this with an IR remote based curtain.
[0004] However, present devices/ systems operate a curtain in either a vertical or a
horizontal plane and thereby do not provide for a more aesthetic profile of an open curtain to be
achieved. Further, present systems do not provide for a dual-axes motion wherein the curtain can
move both along a horizontal plane and a vertical plane.
[0005] Hence there is a need in the art for a system that can operate a curtain to achieve a
more aesthetic profile of the curtain, and for a system that enables a curtain to be moved in both
planes for better and more aesthetic operation of the curtain.
OBJECTS OF THE PRESENT DISCLOSURE
[0006] Some of the objects of the present disclosure, which at least one embodiment
herein satisfies are as listed herein below.

[00046] In an aspect, present disclosure elaborates upon a method for operating a curtain.
The method can include: affixing one end of a rope on the curtain’s opening side at a point
between top and bottom of the curtain; configuring other end of the rope to be above the one end
and towards other side of the curtain; and pulling the rope towards the other end for opening the
curtain, wherein the pulling can provide a semi-parabolic profile to the opening side.
[00047] In another aspect, the method can include passing the rope through a pathway
configured on the curtain to ensure proper movement of the rope.
[00048] In yet another aspect, the pathway can include any or combination of holes,
hooks, rings, hoops and sleeves, and wherein the holes, the hooks, the rings, the hoops and the
sleeves can be configured on the curtain.
[00049] In an aspect, present disclosure elaborates upon a system for operating a curtain.
The system can include: a rope configured to be affixed at its one end on the curtain’s opening
side at a point between top and bottom of the curtain, other end of the rope configured to be held
above the one end and at an angle to the opening side; and a device configured to pull the rope
towards the other end for opening the curtain, wherein the pulling can provide a semi-parabolic
profile to the opening side.
[00050] In another aspect, the system can be coupled with another system that can move
the curtain along a horizontal axis thereby leading to a dual-axes curtain operation system for
moving the curtain in both a horizontal plane and a vertical plane.
[00051] In yet another aspect, the device can include a motor adapted to drive a worm
gear, the worm gear driving a round gear operatively connected to a rope winder that winds the
rope towards the other end for opening the curtain, and unwinds the rope away from the other
end for closing the curtain.
[00052] In an aspect, the motor can provide motive power to the another system as well.
[00053] In another aspect, the motor can be a stepper motor.
[00054] In yet another aspect, the rope can be configured to pass through a pathway
configured on the curtain to ensure proper movement of the rope.
[00055] In an aspect, the system can be configured for any or a combination of global
mode of operation, local mode of operation, scheduled operation, human presence detection
9

based operation, mobile application based operation, capacitive glass touch based operation, and power backup.
[00056] FIG. 1 illustrates a present system to open and close a curtain along a horizontal
axis (Prior art).
[00057] As illustrated in FIG. 1, in an exemplary embodiment a present system 110 to
operate a curtain 110can include a motor 104 operatively coupled via a gear 106 to a toothed belt (not shown) that can move within a channel 108. A hook (say a first hook) can be affixed on the belt and can be configured to slide in the channel 108. One end of top edge of a curtain 102 can be hung from the first hook. The channel 108 can also hold other hooks configured to slide freely in the channel and such hooks can hold intermediate portions of top edge of the curtain 102. Other end of top edge the curtain 102 can be hung from a fixed hook (say a second hook) that may as well be configured in the channel 108 itself.
[00058] As can be readily understood, when (shaft of) motor 104 rotates, via gear 106 a
linear motion can be imparted to the toothed belt. Thus the first hook can move linearly in
channel 108 carrying one end of top edge of the curtain 102 along with it and thereby the curtain
102 can get opened/drawn. Reversal of rotation direction of the motor 104 reverses the direction
of travel of the first hook and thereby the curtain 102 can be folded/closed. In this manner the
curtain 102can get a linear motion along X-axis and can move in a horizontal plane.
[00059] While above elaborates upon a single curtain (also termed as single side curtain ),
two curtains can likewise be configured using same channel ( as shown in FIG. 1) and can move towards or away from each other along a horizontal axis ( say X-axis), leading to a centrally open –close system. That is, in such a system, two sub-curtains can be used in the same manner which is being used in single side opening curtain. As shown, here two curtains (interchangeably termed sub-curtains) can be configured on channel 108 on opposite sides, their other two sides being connected to the toothed belt facing each-other ( so as to reflect each other’s motion) when only one motor similar to 104 can be used. In another configuration, entirely separate curtains and their corresponding curtain operating systems can be independently used, that is, each end of a channel holding such curtains can be operatively configured with a motor and components as described above.
10

[00060] FIG.2 elaborates upon proposed system in accordance with an exemplary
embodiment of the present disclosure.
[00061] Proposed disclosure enables a system that can open a curtain in a semi-parabolic
profile leading to a more aesthetic look in a room.
[00062] In an aspect, proposed system can include a rope 202 configured to be affixed at
its one end 202-a on opening side 206 of a curtain (such as curtain 102 in FIG. 1) at a point between top and bottom of the curtain 102, it’s other end 202-b configured to be held above the one end 202-a and at an angle to the opening side 206; and a device 204 configured to pull the rope 202 towards the other end 202-b for opening the curtain, wherein the pulling can provide a semi-parabolic profile to the opening side 206.
[00063] In yet another aspect, the device 204 can include a motor 208 adapted to drive a
worm gear 210, the worm gear driving a round gear 212 operatively connected to a pulley/rope winder 214 that can wind the rope 202 towards the other end 202-b for opening the curtain 102, and can unwind the rope 202 away from the other end 202-b for closing the curtain 102 when direction of rotation of motor 208 is reversed..
[00064] As can be understood, winding the rope 202 in manner as elaborated above can
lead to the opening side 206 of the curtain shift from an initial vertical edge profile to a semi-parabolic profile as shown in FIG. 3, while unwinding the rope can lead to the semi-parabolic profile of the opening edge 206 gradually losing its curvature and finally coming back to its initial vertical edge profile as shown in FIG. 2.
[00065] In an exemplary embodiment, proposed system can be affixed on one end of
channel 108 itself, as shown.
[00066] In this manner, proposed system to operate a curtain can open a curtain in a more
aesthetic emi-parabolic profile. It can be readily appreciated that the system as described above
can be configured on curtains configured on both sides of a window or a door etc. so as to have
semi-parabolic profiled curtains when open on both sides, as illustrated in FIG. 3.
[00067] In another aspect, the proposed system can as well work with another system for
opening and closing the curtain along a horizontal axis, for instance system 110 as elaborated above (FIG.1). Both the systems working together can lead to a third system that can provide a
11

dual-axes motion wherein the curtain can move both along a horizontal plane and a vertical
plane.
[00068] In an exemplary embodiment, same motor (such as motor 208) can function as
motor 104 as well, thereby operating both the systems together. In such a system, as motor 208
moves, a curtain connected as above can move in a horizontal plane, and its opening edge can
achieve a semi-parabolic profile while the curtain also moves in a vertical plane.
[00069] In an aspect, rope 202 can be passed through a pathway configured on the curtain
102 in such a manner as to ensure the rope’s proper movement. As further elaborated (FIG. 6),
the pathway can be made using any or a combination of holes, hooks, rings, hoops and sleeves
and the like.
[00070] FIG.3 illustrates how proposed system can be used in a two curtain configuration
in accordance with an exemplary embodiment of the present disclosure.
[00071] As illustrated in FIG.3, proposed system can be configured on both sides of a
channel 108 and can operate two curtains 102-1 and 102-2 whereby opening a curtain (
either102-1 or 102-2) using proposed system can lead to a semi-parabolic profile on the opening
side of the curtain.
[00072] In an aspect, a system 110 can also be provided as shown (along with the
proposed system ) that can move curtains 102-1 and 102-2 along a horizontal axisin a horizontal
plane towards and away from each other, as already elaborated.
[00073] As can be readily appreciated, proposed system and system 110 can be integrated
to form a third system that can enable a dual-axes operation of a curtain wherein both horizontal
and vertical operation can be performed, horizontal operation leading to movement of the curtain
in a horizontal plane and vertical operation leading to a semi-parabolic opening of the curtain in
a vertical plane.
[00074] FIG. 4 elaborates upon components of device used in proposed system in
accordance with an exemplary embodiment of the present disclosure.
[00075] As already described and shown in detail in FIG. 4, proposed system can include
device 204 that can in turn include motor 208 configured to drive worm gear 210 that in turn
drives round gear 212 that can in turn rotate pulley / rope winder 214. Rope winder 214 can
accordingly wind/unwind the rope 202 as already elaborated.
12

[00076] FIG. 5 elaborates upon a method of implementing proposed system in accordance
with an exemplary embodiment of the present disclosure.
[00077] Present disclosure elaborates upon a method for opening a curtain. The method
can include, at step 502, affixing one end of a rope on the curtain’s opening side at a point
between top and bottom of the curtain; and at step 504, configuring other end of the rope to be
above the one end and towards the curtain’s other side.
[00078] The method can include, at step 506, pulling the rope towards the other end for
opening the curtain, wherein the pulling can provide a semi-parabolic profile to the opening side.
[00079] FIG. 6 illustrates a method of arranging a rope of the proposed system on a
curtain in accordance with an exemplary embodiment of the present disclosure.
[00080] In an aspect, rope 202 can be passed through a pathway configured on the curtain
in such a manner as to ensure the rope’s proper movement. The pathway can be made using any
or a combination of holes, hooks, rings, hoops and sleeves.
[00081] In an exemplary embodiment as illustrated in FIG. 6, rope 202 can be passed
through holes 602, 604, 606, 608, 610 and 612 where one end of the rope ( end 202-a) can be
held in hole 602 , while the other end ( end 202-b) can be held in hole 612 of a curtain 102.
[00082] As can be seen, hole 602 is at a point between top and bottom of curtain 102,
while hole 612 is above hole 602 and towards other side (the non-opening side) of curtain 102. In
this manner, rope 202 can be similarly held in these and other holes.
[00083] As end 202-b is pulled, curtain 102 can start getting folded at various holes
configured therein.
[00084] In an exemplary embodiment, curtain 102 can be part of a two curtain system.
The curtain 102 can be held in a channel 2W long (similar to channnel108) . First, curtain 102
can be folded by a distance of W/2 as shown along horizontal X-axis ( using , for instance,
system as elaborated in FIG. 1).Thereby rope 202 can be pulled along end 202-b when the holes
can start following a parabolic trajectory represented by equation :
Y =-W/2 + X2
wherein X-axis and Y-axis areas indicated, with co-ordinates [0,0] lying at point 614 as
illustrated. As can be understood, coordinates at 602 can be [-W/2,0].
13

[00085] In an exemplary embodiment, a light weight can be strung at end 202-a. Weights
can as well be configured on lower edge of curtain 102 so that the curtain folds nicely. Number of folds can be determined by that of holes through which rope 202passes.
[00086] As can be readily understood, proposed system can be operatively configured
with other systems and devices for its better working. Components of the system can as well be of different types. For instance, motor 208 can be a stepper motor. Motor 208 can be configured to be operated by any remote means such as Internet and infra-red. Using Internet a global mode of operation can be achieved wherein the proposed system can be operated from anywhere in the world, while using Infra-red a local mode of operation can be had. A mobile application can be configured to operate motor 208. The mobile application can enable capacitive glass touch control herein the curtain can be opened /closed by means of sliding a finger across display of a mobile device. Power backup (such as a battery) can be provided for operation of the motor 208 in case of failure of normal power. Appropriate sensors (such as passive infrared - PIR sensors) can be provided to open /close the curtain using proposed system based upon presence /absence of humans. A schedule for the opening and closing of curtains using proposed system can as well be set.
[00087] As used herein, and unless the context dictates otherwise, the term “coupled to” is
intended to include both direct coupling (in which two elements that are coupled to each other or in contact with each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously.
[00088] Moreover, in interpreting both the specification and the claims, all terms should
be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C ….and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
14

[00089] While some embodiments of the present disclosure have been illustrated and
described, those are completely exemplary in nature. The disclosure is not limited to the embodiments as elaborated herein only and it would be apparent to those skilled in the art that numerous modifications besides those already described are possible without departing from the inventive concepts herein. All such modifications, changes, variations, substitutions, and equivalents are completely within the scope of the present disclosure. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
