Reversible roller shades with light reflective and heat absorbing roller fabric
We disclose a roller shade which may move the roller fabric to position either a light reflecting section or a heat absorbing section of the roller fabric toward a window. The two sections may be on opposite sides of a sheet of roller fabric which is connected to the roller tube at one end. The roller shade may wind the roller fabric around the roller tube then reverse the side of the roller fabric which faces the window. Alternatively, the roller fabric may be a continuous loop of fabric that includes a light reflecting section and connected to a heat absorbing section. The roller shade may move the continuous loop of fabric to position either section toward the window. The roller shade may include sensors, a motor, and a controller. The controller may be programmed to reverse the roller fabric in response to a sensor measurement.
1. A roller shade comprising:
a roller tube, the roller tube comprising an inner volume, the inner volume comprising:
a reversible motor, within a gearbox, wherein the reversible motor is operably connected to the roller tube;
a battery, wherein the battery is operably connected to the reversible motor;
a controller adapted to be programed by a mobile device; and
a roller fabric, the roller fabric comprising:
a loop with two sections;
a first section comprising a light reflective material;
a second section comprising a heat absorbing material;
a weighted member, comprising a slot, wherein the roller fabric slides through the slot;
wherein, when the light reflective material is positioned toward a window, solar light is reflected;
wherein, when the heat absorbing material is positioned toward the window, heat is absorbed; and
wherein the loop winds around the roller tube and through the slot in the weighted member to position either the first section or the second section of the roller fabric toward the window.
2. The roller shade of claim 1 , wherein the light reflective material consists of one of the following: aluminum, Mylar, chrome, silver, nickel, or copper.
3. The roller shade of claim 1 , wherein the roller tube further comprises at least one sensor for monitoring an environmental condition.
4. The roller shade of claim 1 , further comprising an audio sensor, wherein the audio sensor detects a plurality of voice commands, and wherein the audio sensor sends one of a plurality of signals to the controller in response to one of the plurality of voice commands, and wherein the controller actuates the reversible motor to raise, lower, or reverse the roller fabric in response to one of the plurality of voice commands.
5. The roller shade of claim 3 , wherein the at least one sensor comprises a visible light sensor, wherein the visible light sensor sends a signal to the controller that the visible light sensor has detected a defined light measurement within the wavelengths of visible light, and wherein the controller actuates the reversible motor to reverse the roller fabric in response to the signal.
6. The roller shade of claim 3 , wherein the at least one sensor comprises an ultraviolet light sensor, wherein the ultraviolet light sensor sends a signal to the controller that the ultraviolet light sensor has detected a defined measurement of light within the wavelengths of ultraviolet light, and wherein the controller actuates the reversible motor to reverse the roller fabric in response to the signal.
7. The roller shade of claim 3 , wherein the at least one sensor comprises a temperature sensor, wherein the temperature sensor sends a signal to the controller that the temperature sensor has detected a defined minimum or maximum temperature, and wherein the controller actuates the reversible motor to reverse the roller fabric in response to the signal.
8. The roller shade of claim 1 , further comprising a programmable controller with memory for storing program code.
9. The roller shade of claim 8 , wherein the memory stores a program code that receives signals from a mobile device.
10. The roller shade of claim 8 , wherein the memory stores a program code which signals the reversible motor to reverse the roller fabric at defined times of day.
