发明名称 VACUUM CLEANER HOSE
摘要 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 wounding 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. In still another embodiment, the hose 1 is formed from two rows of the band-shaped materials in which each of the two rows of the band-shaped materials 2 has the hollow protrusions 4 inserted with the electric wire 5, and the hollow protrusions 4a inserted with no electric wire 5. Thus, the amount of use of the electric wire 5 in the hose 1 is reduced.
