  • Vacuum cleaner hose with an electrical conductor
    Patent number: 4368348
    Abstract: A vacuum cleaner hose is equipped with an electrical cable which runs in parallel to the longitudinal axis of the vacuum cleaner hose in a groove or in contact with a flattened portion of the vacuum cleaner hose which is encased together with the electrical conductor by an outer jacketing hose. Alternately, the cable may be enclosed in a smaller diameter hose which in turn is connected to the outer wall of the vacuum cleaner hose in the groove formed in the vacuum cleaner hose. The electrical cable may be embedded in a foam material which forms a segment of the vacuum cleaner hose inside the jacketing hose.
