The disclosed device concerns curtain rods. More particularly, it relates to a motorized curtain rod system which is assemblable in a modular fashion from a worm screw drive member formed to length from a plurality of worm screw segments positionable within a housing surrounded by a supporting curtain rod.
For centuries, window coverings, such as curtains, hanging shades, and draperies and the like have been employed in homes and offices. Such are used for many purposes such as for the provision of decoration, privacy, and to limit or filter the light entering a window into a room or building. Whether employed for functional or aesthetic purposes, such window coverings conventionally have an open position where they are retracted and a closed position where they have been drawn to cover the window entirely. When used to adjust or filter the amount of light entering a room, such window covering can be located to an infinite number of positions between the retracted and closed positions.
In addition to being locatable to an infinite number of positions for light transmission purposes and privacy, there are also an infinite number of window coverings conventionally available for this purpose. For brevity curtains is a term employed herein for such window coverings and as so used is intended to describe and define any and all of these types, forms and window covering designs including blinds, shades, draperies, and the like, which are mounted in an adjustable sliding position on a curtain rod.
Conventionally, such curtains are engaged to hang in a sliding engagement with a curtain rod. The curtain rod is positioned adjacently above the window to be covered by the drawn curtains. Such curtain rods are held to the wall in a position spaced from the wall and underlying window by mounting brackets. In use, the supported curtains in this sliding engagement to the curtain rod may be pulled or drawn between the retracted position covering or adjacent one or both sides of the window and a closed position. The curtains may be drawn to completely cover the window to block light and/or provide privacy to the occupant of the room, they may be moved to the retracted position providing the most light transmission into the room, or they may be drawn to any of an infinite number of positions therebetween.
The vast majority of such curtain rod and hanging curtain systems are manually operated. Users will either pull or push a leading edge of the sliding-engaged curtain or curtains to and between the retracted and closed positions.
The system disclosed herein provides a motorized curtain hanging and positioning system, which employs a segmented drive rod allowing for easy installation to windows of varying width. Once installed and engaged to the desired curtain, it may be remotely activated to move the hung curtain or curtains between the retracted and closed positions in front of the chosen window.
The forgoing examples concerning curtain rod hanging systems and issues regarding such, are intended to be illustrative and not exclusive, and they do not imply any limitations on the invention described and claimed herein. Various other limitations of the related art are known or will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings.
The system herein provides a solution to the shortcomings of conventional powered and non powered curtain rods through the provision of and easily-assembled electric powered curtain rod support system.
In all modes, the system employs a support rod adapted for engagement of a curtain therewith which is moveable between a retracted position and closed position. The system is rendered especially adaptable to the required length for an individual window through the provision of components which may be trimmed for length and then assembled to form the curtain support device.
A curtain rod having axial passage therein, is configured for the positioning of a sleeve therein once both have been sized according. The sleeve has a plurality of ribs radially projecting therefrom to distal ends which contact an interior wall of the curtain rod which defines the axial passage. These ribs hold the sleeve in operative positioning with a sleeve slot aligned with support member slot.
An axial passageway running the length of the sleeve and in communication with the sleeve slot, is sized for operative rotation of an elongated drive member therein. This drive member has a threaded exterior in the form of a worm screw drive member which engages with the mating recesses in a body of one or a plurality of powered support carriers. Support members engaged to the body of each powered carrier, project through both the sleeve slot and the support member slot and extend its distance from the exterior wall of the support member. The distal end of each support member is configured to engage with the leaded end of a respective curtain hung from the support member. Conventional, sliding, non powered support members engage with the support member to hold the weight of the supported curtain between the leading end and opposite end.
Particularly preferred in all modes of the system herein, are drive member segments, which may be assembled to form a worm screw drive member of a length appropriate for the window and curtain of choice. Also particularly preferred is the configuration of the drive member with a double helix or dual start formation of the formed worm screw type threaded exterior. Such is preferred for the significant increase in speed of the opening and closing of an attached curtain, and for the dual engagement with separate great tracts on the drive member with mating recesses formed in the body of the powered carriers. This dual helix, dual thread engagement, imparts additional torque to the powered carrier to move it along the drive member, and provides a stronger engagement and backup should one of the threads on the elongated member become damaged since the other will continue to translate the powered carrier and the curtain hung from the support rod.
One, or a plurality of electric motors, are operatively connected to the respective assembled and operatively-positioned drive members employed on a support rod. Power for each such electric motor may be provided by a battery engaged to the support rod and/or by AC power from the building. For dual curtains, which close at a central location on a window, two drive members may be employed with one being a right handed dual helix thread and the other being a left handed dual helix thread configuration. Such allows for the curtains to translate toward each other during closing and away from each other during opening of the hung curtains.
Where multiple curtains are hung from multiple assembled support rods, a controller may be employed to concurrently open and close all of the multiple curtains. Using a feedback circuit and monitoring of the electric current used by each electric motor in the plurality, and software adapted to the task, the controller can control the speed of each respective motor in the plurality, to cause each respective curtain to reach its open or closed position at the same time. The software on the controller will learn when each curtain reaches its fully closed or open position by monitoring the electric current used in each motor, which will rise significantly once a curtain reaches a maximum point of closing or opening since the motor will slip on a clutch, but concurrently show a peak current use. By monitoring each motor to ascertain the time needed for translating to reach each open and closing peak, the software on the controller will adapt and change the speed of each motor in the plurality to cause them to all reach the retracted or open position and the closed position at once.

This double helix of parallel helical worm screw 28 threads, thus provides two different projecting threads for engagement within the complimentary threaded cavity 32 of a powered carrier 30 which would also have two threads and two thread recesses therebetween. This double helix winding provides a significant increase in the speed in which the powered carrier 30 translates in both directions upon the drive member 26. Additionally, the two individual worm screw threads such as a first helical thread 58 and a second helical thread 60, both independently impart power during rotation of the drive member 26, to the powered carrier 30. Thus, torque force is more equally communicated and should one of the two helical threads 58 or 60. Further, should either the first helical thread 58 or second helical thread 60 become damaged, the system 10 will still operate since the other of the two helical threads 58 or 60 will still be engaged with the complimentary threaded cavity 32 which also has two independent helical threads and passages therebetween.

As noted above, when multiple curtains are hung from multiple assembled support rods 12, the controller 47 may be employed to concurrently open and close all of the multiple curtains. For example, using a feedback circuit 43 or the like, monitoring the electric current used by each electric motor 42 in the plurality, and software adapted to the task, the controller 47 can control a rotation speed of each respective motor 42 in the plurality, to control the translation of teach respective powered carrier 30 to reach a respective open or closed position of an engaged curtain at the same time. The software on the controller 47 is configured to learn when each curtain reaches its fully closed or open position by monitoring the electric current used in each motor 42, which will rise significantly once the powered carrier 30 engaged to a curtain reaches a maximum point of closing or opening. This is because the motor 42 will slip on a clutch but concurrently show a peak current use. The software is configured for calculating appropriate motor speeds to achieve appropriate translation speeds of the individual powered carriers 30 to cause reaching concurrent closed and open positions at the same time.
