  • window coverings for example, horizontal (Venetian) blinds, roll-up shades, pleated shades, Roman shades, honeycomb shades and vertical blinds, all have operating systems which differ according to their modes of operation.
  • window covering of all types have been operated manually through the manipulation of cords and rods.
  • Motorized systems for operating window coverings have also been developed, wherein the control to operate the opening may be located on the covering assembly itself or may be contained in a remote control device.
  • these motorized window coverings are actuated by electric motors that are powered by batteries contained in the window covering assembly. It can be appreciated that the batteries must be periodically replaced or recharged.
  • PC's photovoltaic cells
  • PC's are expensive and relatively large PC arrays can significantly effect the cost of a solar-powered window covering assembly.
  • Several prior art systems have utilized a PC array that is separately attached to the window frame and has an electrical cord running to the window covering and the motor contained therein.
  • the PC array can be placed lower on the window where it will receive more direct light but this arrangement is more difficult to install requiring two separate and distinct items to be attached to the window frame. Furthermore, if the PC is placed relatively low on the window, it may be visible when the window covering is retracted, thereby obstructing the view out of the window, as well as, being aesthetically displeasing.
  • U.S. Patent 4,807,686 of J. Schnebly teaches to place the PC array and the associated motor and batteries in either a foot rail or the head rail of a pleated shade, wherein the powered head rail or foot rail moves along a pair of opposed tracks that are mounted to either side of the window frame.
  • the purpose of the Schnebly design was to provide a motorized window covering that could be utilized on non- vertical and curvilinear window surfaces, such as those that might be found in a greenhouse, or with a skylight, as well as, standard vertical windows.
  • the foot rail will typically be powered permitting it to move up the vertically mounted tracks, thereby retracting the pleaded shade.
  • the PC array By mounting the PC array in the foot rail, the PC array is going to be incident to a greater amount of light than a similarly sized PC array that is mounted in a head rail.
  • the Schenbly design is not optimized for use on vertical surfaces, requiring the installation of not only the window covering itself but two opposed and parallel tracks as well.
  • the parallel tracks must be installed with a relatively high degree of precision in order for the foot rail to move along the tracks properly, thereby increasing the cost of installation.
  • the tracks when the window covering is in its retracted position, the tracks are exposed to view and may be aesthetically displeasing.
  • Prior art window coverings incorporating PC's typically utilize rechargeable nickel cadmium batteries to provide supplemental power to the motor during daylight operation of the window covering and to store PC generated electrical power for nighttime use of the window covering.
  • Nickel Cadmium batteries suffer from "memory effect," wherein over time the batteries are only able to hold a charge similar to the amount they have been discharged during use. Since motorized window coverings are generally operated for a very short period of time between recharges, they are only slightly discharged, and after awhile the capacity of the batteries will be reduced to this level of discharge. Consequently, a window covering using nickel cadmium batteries may only be able to open and close once or twice before the memory-effected capacity of the batteries is reached.
  • nickel cadmium batteries must be nearly fully discharged between rechargings on a regular basis; however, this does not occur in a motorized window covering that incorporates PC's since the PC's constantly recharges the batteries when light is present.
  • a window covering having an electric motor to retract the covering is described.
  • the electric motor is powered by a PC array and a set of rechargeable batteries.
  • the PC array is an integral component of the window covering assembly and is arranged below the head rail of the covering when the covering is in its extended position to maximize the amount of light incident on the PC's.
  • rechargeable alkaline manganese (RAM) batteries are specified for use in conjunction with amorphous PC's as the power supply for an electrical circuit that can be utilized in a variety of applications, such as the solar powered window coverings described herein.
  • RAM batteries are more ideally suited to use in shallow cycle applications wherein the batteries are only discharged a few percent of their capacity between uses, such as the case with motorized window coverings, and RAM batteries, unlike Nickel Cadmium batteries, do not suffer from "memory effect.”
  • Amorphous PC's are preferable over crystalline PC's because they are capable of generating useful voltages at light levels significantly below those required by crystalline PC's. By combining the two and providing a Zener diode electrically coupled in parallel therewith an ideal circuit for use in shallow cycle applications is created.

  • the PC array retracts with the window covering when the covering is raised so that the PC array is hidden from view and does not obstruct vision through the window.
  • FIG. 1 shows a basic lift circuit 1 for a window covering in accordance with various embodiments the present invention.
  • An amorphous PC array 5 which comprises one or more PC's, is electrically connected to a RAM battery pack 10.
  • Amorphous PC's are capable of producing useful voltages in both direct and indirect sunlight albeit at low levels of current output. As the amount of light incident on the amorphous PC's increases, so does their output voltage. Accordingly, the voltage level of an amorphous PC array configured to produce charging voltages at low light levels will generally produce voltages significantly in excess of the voltage rating of the battery pack when exposed to higher light levels such as direct sunlight.
  • the voltages produced at lower light levels by each crystalline PC in a crystalline PC array is very small and a crystalline PC array typically cannot provide a sufficient charging voltage for a typical battery pack 10 unless a relatively large and consequently expensive crystalline PC array is utilized.
  • a crystalline PC array capable of producing sufficient charging voltage at the same low light levels as an amorphous PC array might require ten times as many PC cells.
  • Another advantage of amorphous PC's over crystalline PC's is that they are typically much less expensive. Amorphous PC's suffer from an output degradation of approximately 20% over time; therefore, the PC array must be sized for a given application accordingly.
  • the battery pack 10 comprises one or more RAM cells that are connected in series and/or parallel with each other depending on the voltage level desired to operate the basic lift circuit 1.
  • RAM batteries do not exhibit "memory effect.”
  • “Memory effect” is a condition that occurs when a battery is charged to the same level several times consecutively. The battery develops a chemical "memory" of that level and will not allow a charging past that point. Although some of the capacity of a RAM battery may be lost over successive recharging cycles, the battery will retrain a capacity that is significantly greater than the amount that the RAM battery has been typically discharged.
  • a typical RAM battery has a discharge/recharge cycle life of around 20 if discharged to 75% of its capacity; whereas, a typical RAM battery will have a life of approximately 20,000 cycles if discharged to under 1% of its capacity. Raising or lowering of a typical window covering requires only a very small percentage of the capacity available from a RAM battery pack 10. Since RAM batteries in the battery pack 10 do not exhibit "memory effect,” additional capacity is available between recharging cycles to raise or lower the blinds multiple times if required. Testing has indicated that after about 15,000 1% cycles RAM batteries retain around 75% of their original capacity.
  • RAM batteries are susceptible to damage from excessive charging voltages such as those that might be produced by the PC array 5 when exposed to direct sunlight. Accordingly, a Zener diode 15, or a functional equivalent, is provided to limit the voltage input into the RAM battery pack 10 to below 1.65 volts per RAM battery wired in series. Zener diodes having a 2% variation tolerance are preferred. In a battery back having 8 RAM batteries in series a 1N4743C Zener diode is preferred having a 13 volt rating and a 1 watt capacity. In a battery pack having 4 RAM batteries in series, a 1N4736C Zener diode is preferred having a 6.8 volt rating and a 1 watt capacity.
  • Voltage regulating circuitry can be used in place of the Zener diode in alternative embodiments. It is contemplated that in alternative embodiments other types of rechargeable batteries may be utilized in the battery pack 10, especially rechargeable batteries that do not suffer from a "memory effect", wherein such alternative battery types may or may not require the use of a Zener diode 15 to control the current flow of the PC array 5.
  • a control circuit 20 is provided which routes electrical current from the battery pack 10 or the PC array 5 to a motor 30 in the proper direction depending on whether the window covering is being lifted or lowered by reversing the direction of current flow. Signals to raise or lower the window covering are transmitted from a remote control to an infrared or radio receiver (not shown) that is coupled to the control circuit.
  • the motor 30 is mechanically coupled to a mechanism for raising or lowering the window covering. For example, an output shaft of the motor 30 may turn a capstan which winds up one or more lift cords, or it may rotate a roller which winds up a fabric shade, neither of which is shown.
  • a limit switch system 35 may be provided that turns off power to the motor 30 when the window covering has been fully extended or retracted.
  • the control circuit 20 may also be operated by one or more switches that are electrically coupled to the control circuit 20 in place of or in addition to the infrared or radio receiver 25.
  • Figure 2 illustrates generally the desirability of locating a PC array below the head rail 40 of the window covering.
  • the head rail 40 is mounted to a header 45 spanning a window opening.
  • the header 45 itself and the window framework 50 effectively block direct sunlight from impinging on the rear vertical surface 55 of the head rail 40 facing towards the window. Only incident light that has been reflected from other surfaces and has not been absorbed will hit the vertical surface 55.
  • the intensity of the indirect sunlight incident on the vertical surface 55 is much less than that of direct sunlight and accordingly, a PC array located on the vertical surface 55 will produce less electricity than a PC array 5 located directly in front of the window pane(s) 65 that receives direct sunlight.
  • the intensity of the indirect light through the window will be greater on a PC array 5 located facing the window panes then one located on a head rail 40 behind the window framework 50.

  • the solar powered lift system as described herein is incorporated by way of example in three types of window covering assemblies: a cellular shade, a roman shade, and a roll-up style shade. It is understood that this system may be adapted for retracting other types of window coverings, such as Venetian blinds and Silhouettes TM produced by Hunter Douglas, the assignee of this application, as would be obvious to one of ordinary skill in the art with the benefit of this disclosure.
