  • Patent number: 7418980
    Abstract: The present invention relates to a vacuum cleaner hose manufactured by continuously spirally winding one row or two rows of band-shaped materials extruded with an electric wire inserted therein. The vacuum cleaner hose is formed by spirally winding and sticking a band-shaped material having protrusions connected to each other in a line. In one embodiment, the vacuum cleaner hose is formed from one row of the band-shaped material 2 having a plurality of the hollow protrusions 4 inserted with the electric wire 5 and at least one hollow protrusion 4a inserted with no electric wire 5 is formed into the hose 1. In another embodiment, the vacuum cleaner hose is formed from two rows of the band-shaped materials 2 in which the protrusions of only one row of the band-shaped materials 2 are inserted with the electric wire 5.
