The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
Additionally, the set of window blinds 12 includes a plurality of adjustment lines 22. Each of the adjustment lines 22 extends between the upper housing 16 and the lower member 18 and each of the adjustment lines 22 engages each of the slats 20 for adjusting an angle of the slats 20. Moreover, each of the slats 20 has a top surface 24 and each of the slats 20 is adjustable such that the top surface 24 of each of the slats 20 is oriented to lie on a plane forming an angle with a lower side 26 of the upper housing 16. The lower member 18 has a first end 28 and a second end 30, and a pair of pins 32 is each coupled to and extends away from a respective one of the first end 28 and the second end 30. Each of the pins 32 might engage a track, or other similar structure, that is integrated into a frame of the window 14 for retaining the lower member 18 at a preferred location.
A plurality of solar cells 34 is provided and each of the solar cells 34 is positioned on a respective one of the slats 20. In this way each of the solar cells 34 can be exposed to sunlight passing through the window 14. Additionally, each of the solar cells 34 is positioned on the top surface 24 of the respective slat 20 having the solar cells 34 on the respective slat 20 completely cover the top surface 24 of the respective slat 20. A plurality of conductors 36 is each electrically coupled to each of the solar cells 34 on each of the slats 20 and each of the conductors 36 extends into the upper housing 16.
An adjustment unit 38 is provided and the adjustment unit 38 is integrated into the set of window blinds 12. The adjustment unit 38 is in mechanical communication with the plurality of slats 20. Moreover, the adjustment unit 38 adjusts an angle of the plurality of slats 20 to facilitate the plurality of solar cells 34 to capture the maximum amount of solar energy. The adjustment unit 38 comprises a control circuit 40 that is positioned in the upper housing 16. The control circuit 40 is electrically coupled to each of the conductors such that the control circuit 40 is in electrical communication with the plurality of solar cells 34.
The adjustment unit 38 includes a drive shaft 42 that is rotatably positioned within the upper housing 16 and a pair of pulleys 44. Each of the pulleys 44 has the drive shaft 42 extending therethrough and the pulleys 44 are spaced apart from each other on the drive shaft 42. Additionally, each of the pulleys 44 has a respective one of the adjustment lines 22 being wrapped therearound. The adjustment unit 38 includes a motor 46 that is positioned in the upper housing 16 and the motor 46 is electrically coupled to the control circuit 40. The motor 46 rotatably engages the drive shaft 42 and the motor 46 rotates the drive shaft 42 in a first direction or a second direction. Each of the slats 20 is tilted in a first direction when the motor 46 rotates the drive shaft 42 in the first direction and each of the slats 20 is tilted in a second direction when the motor 46 rotates the drive shaft 42 in the second direction. The motor 46 may comprise a bi-directional electric motor or the like.
The adjustment unit 38 includes a signal analyzer 48 that is positioned in the upper housing 16. The signal analyzer 48 is electrically coupled to the control circuit 40 such that the signal analyzer 48 is in electrical communication with the plurality of solar cells 34. The motor 46 is actuated to rotate in either the first direction or the second direction until the signal analyzer 48 determines the point at which the plurality of solar cells 34 produces the highest intensity of output. In this way the signal analyzer 48 ensures each of the slats 20 is positioned at the optimal angle for exposing the solar cells 34 to sunlight.
A thermometer 50 is provided and the thermometer 50 is coupled to the set of window blinds 12. In this way the thermometer 50 is in thermal communication with the window 14 in which the set of window blinds 12 is positioned. The thermometer 50 is electrically coupled to the control circuit 40. Additionally, the thermometer 50 may comprise an electronic thermometer 50 of any conventional design.
A transceiver 52 is positioned in the housing and the transceiver 52 is electrically coupled to the control circuit 40. Moreover, the transceiver 52 is in wireless communication with a thermostat 54 of a heating, ventilation and air conditioning (HVAC) system 56. In this way the transceiver 52 facilitates the HVAC system 56 to respond to the temperature sensed by the thermometer 50. Thus, the HVAC system 56 can increase cooling capacity when the thermometer 50 senses temperatures that exceed a pre-determined threshold temperature. The transceiver 52 may comprise a radio frequency transceiver or the like. As is shown in
A power supply 62 is positioned in the upper housing 16 and the power supply 62 is electrically coupled to the control circuit 40.

The power supply 62 includes a pair of contacts 66 that is each of the contacts 66 is coupled to and extends away from the upper housing 16. In this way each of the contacts 66 can be electrically coupled to an electronic device 68. Additionally, each of the contacts 66 is electrically coupled to the at least one battery 64 to deliver electrical energy to the electronic device 68.
In use, the signal analyzer 48 continually monitors the output of the plurality of solar cells 34 and the slats 20 are adjusted to the optimal angle for maximizing the electrical energy produced by the solar cells 34. The at least one battery 64 stores the electrical energy produced by the solar cells 34 and the contacts 66 can supply the electrical energy to an electronic device 68. Additionally, the thermometer 50 measures the temperature of the window 14 and the transceiver 52 communicates the temperature to the thermostat 54 of the HVAC system 56. In this way the HVAC system 56 can increase or decrease cooling or heating output, depending on the preferences set by a user, in response to the temperature sensed by the thermometer 50.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
