  • Patent number: 6926145
    Abstract: This disclosure describes an electric light strand mounting device for simplifying the installation and removal of light strands from, for example, a holiday tree. The device consists of a light strand receiver and an associated base that rests on a floor or horizontal surface. Indents are provided on the receiver for preventing downward slippage of mounted strands. The receiver is rotatable around a vertical axis; and simultaneously, the base is moveable in any horizontal direction. Both movements are provided in one version, by a unitary base-receiver structure resting on base castors. In another version the receiver is rotatable with respect to a slidable base; but receiver and base are permanently attached to one another. In a third, version, a slidable base and its receiver are mutually rotatable, but are readily detachable from each other by a simple lifting motion. In all versions light strands are installed by feeding one strand at a time onto the receiver as it is rotated.
