  • BATTERY PACK FOR A MOTORIZED ARCHITECTURAL STRUCTURE COVERING
    Publication number: 20180261808
    Abstract: A battery pack for use with a motorized architectural structure covering is illustrated. The battery pack includes a battery tube, and first and second end caps. The battery tube may include a valley portion located between first and second battery cavities for receiving first and second rows of batteries. The second end cap may include one or more projections (e.g., first and second tabs, handle, etc.) to facilitate removal of the battery pack from mounting clips associated with the motorized architectural structure covering. The removable, second end cap may include first and second release buttons extending into the valley portion. The release buttons may have a wider portion adjacent to the second end cap, and a narrower portion extending at least partially into the valley portion. The release buttons preferably include a tapered, for example, triangular, or trapezoidal shape, to extend into the valley portion for facilitating user engagement therewith.
