The present invention relates generally to the field of window shades. In particular, the present application relates to battery powered roller type window shades.
Roller window shade assemblies typically include a shade tube, a piece of shade fabric rolled around the shade tube, and brackets that rotatably couple the shade tube to a wall or ceiling. Motors are used to rotate the shade tube, thereby raising and lowering the shade fabric. The motors are conventionally positioned within the shade tube in order to reduce the overall size of the shade assembly. In some arrangements, wires are run to the motors to provide electrical power from the power grid to the motors. However, in some situations, extending wires to the motors can be difficult or unsightly. By way of example, buildings with solid concrete walls prohibit running wires through the walls, requiring the wires to be visually exposed. Alternatively, some shade assemblies include batteries that power the motors. For example, batteries can be positioned outside of the shade tube and connected to the motor with a wire. However, this arrangement requires additional space for the batteries outside the shade tube and can leave the batteries visually exposed. In another example, batteries can be positioned inside of a motor that is inserted into a shade tube.
Accordingly, it is an object of the present invention to provide a battery powered window shade assembly.
It is a further object of the present invention to provide a battery powered window shade assembly with the batteries carried and arranged in the shade tube independent of the motor assemblies.

The motor adapter 212 is configured to couple the motor 108 to the battery support 210. The motor adapter defines a pocket, aperture, chamber, or receiver, shown as receiver 220, configured to receive an end of the motor 108. The motor 108 defines a pair of protrusions, shown as pins 222, offset from the central axis 103 and extending longitudinally towards the motor adapter 212. The pins 222 are received in corresponding apertures defined by the motor adapter 212, fixing against rotation the end of the motor 108 to the motor adapter 212. Alternatively, the pins 222 may be replaced with one or more fasteners extending laterally through both the motor 108 and the motor adapter 212. The battery housing 202 may include clips, fasteners, clamps, a threaded connection, or other components configured to prevent relative longitudinal movement between the end of the motor 108 and the motor adapter 212. The motor adapter 212 may be configured to couple to multiple different brands and types of motors.
The mounting bracket adapter 214 is configured to couple the battery support 210 to the mounting bracket 104. The mounting bracket adapter 214 defines pockets, apertures, chambers, or receivers configured to receive the projections 106 from the mounting bracket 104. The shapes of the apertures and the projections 106 may correspond, and/or the projections 106 may be offset from the central axis 103 such that the projections 106 prevent relative rotational movement between the motor adapter 212 and the mounting bracket adapter 214. The mounting bracket adapter 214 is shown as extending outside of the shade tube 102 such that the mounting bracket adapter 214 is visually exposed. Alternatively, the mounting bracket adapter 214 may be positioned entirely within the shade tube 102 such that the mounting bracket adapter 214 is obscured from view. The mounting bracket adapter 214 may be configured to couple to multiple different brands and types of mounting brackets. The mounting bracket adapter 214 includes an idler roller, shown as crown roller 224, that is configured to rotate freely relative to the mounting bracket and the battery support 210. The crown roller 224 engages an interior surface of the shade tube 102 to rotatably support the weight of the shade tube 102. The crown roller 224 may be splined to key to the inner surface of the shade tube 102. A spacer 223 may be included in the mounting bracket adapter 314 for engaging a distal end of battery support 210.
When the motor 108 exerts a torque on the shade tube 102, the battery housing 202 transfers the torque to the mounting bracket 104 such that the shade tube 102 rotates relative to the mounting bracket 104. Specifically, the motor 108 transfers the torque to the motor adapter 212 through the pins 222. The motor adapter 212 transfers the torque to the battery support 210 through the fasteners 216. The battery support 210 transfers the torque to the mounting bracket adapter 214 through the fasteners 216. The mounting bracket adapter 214 transfers the torque to the mounting bracket 104 through the projections 106.

In other embodiments, the battery bays 204 are each positioned at different radial distances from the central axis 230. The quantity and size of the battery bays 204 and the batteries 206 may be varied. By way of example, the battery support 210 may define a single battery bay 204 that contains one or more batteries 206. The battery bays 204 may be positioned inward such that the battery bays 204 do not extend laterally through the circumference of the battery support 210. The battery bays 204 may have various shapes (e.g., square, triangular, pie-wedge-shaped, etc.). A battery bay 204 may be configured to house multiple batteries 206 at the same longitudinal position. By way of example, a battery bay 204 may extend circumferentially along the battery support 210 through an angle of approximately 160 degrees such that two batteries 206 fit within the battery bay 204.

In some embodiments, the battery pack 200 can be removed from the shade assembly 100 in order to recharge or replace the battery pack 200. To remove the battery pack 200, the battery pack 200 may be pulled away from the mounting bracket 104. The battery pack 200 may be pulled out of the shade tube 102, and subsequently fasteners may be removed to decouple the battery pack from the motor 108. To replace the battery pack 200, a reverse process may be followed. The battery pack 200 may be replaced with another battery pack 200 having charged batteries 206. Alternatively, the mounting bracket adapter 214 may be removed from the battery support 210, and the batteries 206 may be removed from the battery bays 204 and recharged or replaced.
Alternatively, the batteries 206 may be recharged without disassembling the shade assembly 100. As shown in one embodiment of the invention in
The shade 300 includes a material (e.g., sheet, film, etc.) shown as base material 304, and one or more devices (e.g., solar collection units, solar films, photovoltaic arrays or elements, solar panels, etc.), shown as solar membrane 306. The base material 304 may be a shade material that at least partially obstructs the passage of light therethrough. The base material 304 is flexible such that the base material 304 may be rolled and unrolled onto and off of the shade tube 102. The solar membrane 306 is structurally coupled to the base material 304 and functions to receive (e.g., collect, harvest, etc.) light energy (e.g., photons) from a source, such as the sun. The solar membrane 306 may be integrated with the base material 304 (e.g., placed between layers of base material 304) or coupled to (e.g., attached to, adhered to, etc.) the base material 304. The solar membrane 306 may extend across a portion of or the entirety of the length of the shade 300. The solar membrane 306 converts light energy into electrical energy. The electrical energy can then be used to drive the motor 108, stored in the batteries 206, or provided to a surrounding power grid (e.g., the power grid 360, which may be a home power grid, a residential power grid, etc.).

The bearing sleeve 316 is annular and extends around the fixed sleeve 314. The fixed sleeve 314 defines a cylindrical outer surface 320, and the bearing sleeve 316 defines a cylindrical inner surface 322. The cylindrical outer surface 320 and the cylindrical inner surface 322 are approximately the same diameter and engage one another. Accordingly, the bearing sleeve 316 rotates freely about the fixed sleeve 314. The bearing sleeve 316 and/or the fixed sleeve 314 may be made from a material that reduces friction (e.g., bronze, hard plastic, etc.) or include bearing elements such as ball or needle bearings to facilitate such rotation. The fixed sleeve 314 and the bracket 312 each define a flange 317a and 317b, respectively extending radially outward. The bearing sleeve 316 is positioned between the flanges such that the flanges limit or entirely prevent axial movement of the bearing sleeve 316.
The fixed sleeve 314 defines a first set of contacts, shown as annular contacts 324, along the cylindrical outer surface 320. The bearing sleeve 316 defines a second set of contacts, shown as pickups 326, carried along the cylindrical surface, which extend from an exterior side 322a to and interior side 322b. The annular contacts 324 and the pickups 326 are configured such that each pickup 326 engages a corresponding one of the annular contacts 324 in all orientations of the bearing sleeve 316 (e.g., maintaining engagement through an entire rotation of the bearing sleeve 316). In other embodiments, the bearing sleeve 316 includes annular contacts and/or the fixed sleeve 314 includes pickups.
The annular contacts 324 and the pickups 326 are all electrically conductive. The annular contacts 324 are stationary (e.g., fixed relative to the mounting bracket 104 when the shade assembly 100 is installed). The annular contacts 324 rotate with the bearing sleeve 316, which in turn rotates with the shade tube 102. The annular contacts 324 are electrically coupled to one or more components configured to receive electrical energy. These components may be positioned within the shade tube 102 (e.g., the batteries 206, the motor 108, etc.) or the components may be positioned outside the shade tube 102 and electrically coupled to the annular contacts 324 through conductors (e.g., wires, cables, etc.) that extend inside of the shade tube 102 (e.g., the power grid 360, the charging port 250, etc.). The pickups 326 are each electrically coupled to the solar membrane 306 through a conductor or cable, shown as wire 328. The pickups 326 extend radially outward through the bearing sleeve 316 to engage the wires 328. The wires 328 are coupled to an outer surface of the bearing sleeve 316 through a grommet or base plate, shown as wire mount 330.

The electrical energy from the solar membrane 306 is provided to one or more components. The electrical energy can be used to power the motor 108. The electrical energy can be stored in the batteries 206 for later use. The electrical energy can be used to power the controller 350. The electrical energy can be provided to the power grid 360. By way of example, a high-rise office building may include a shade assembly 100 in each window. The electrical energy produced by the shade assemblies 100 may be used to power various functions associated with the building or other structures coupled to the power grid 360 (e.g., powering lights, powering HVAC systems, etc.). In the embodiment shown in
In some embodiments, the controller 350 is configured to automatically raise or lower the shade 300 (e.g., by powering the motor 108 to turn the shade tube 102) in response to certain conditions. In one such embodiment, the controller 350 is configured to monitor a charge level of the batteries 206 (e.g., by measuring an output voltage of the batteries 206, etc.). In response to the charge level falling below a first threshold level (e.g., a threshold voltage, etc.), the controller 350 is configured to control the motor 108 to lower the shade 300. Lowering the shade 300 exposes a greater area of the solar membrane 306 to light. Accordingly, with the shade 300 lowered, the solar membrane 306 produces a greater amount of electrical energy (e.g., a greater wattage), and accordingly charges the batteries 206. The controller 350 may be configured to subsequently raise the shade 300 when the charge level exceeds a second charge level greater than the first charge level. The first charge level and the second charge level may be predetermined and stored in the memory 354. In such a configuration, the controller 350 automatically maintains the charge level the batteries 206 within a usable range, thereby preventing the batteries 206 from draining to a charge level where the user would have to manually charge the batteries 206 (e.g., by supplying electrical energy through the charging port 250, etc.).
The battery bay 402 is centered about the central axis 103 and extends through the entire length of the battery support 400. The battery bay 402 is configured to receive one or more batteries 206. The battery bay 402 has a circular cross section. The battery bay 402 is sized to substantially prevent movement of the batteries 206 except rotation and translation of the batteries 206 about the central axis 103. Accordingly, when one or more of the batteries 206 are inserted into the battery bay 402, the batteries 206 are centered about the central axis 103.
The battery support 400 further defines a slot, shown as wire slot 240, that extends through the entire length of the battery support 400. The wire slot 240 in battery support 400 aligns with a portion of the wire slot 240 defined by the motor adapter 212 and the spacer 318. One or more cables or wires pass through the wire slot 240, electrically coupling the batteries 206, the motor 108, and/or the wires 328. One or more antennas may additionally pass through the wire slot 240.
