電気掃除機用吸引ホース。[Claims for Utility Model Registration] A hollow spiral made of the same resin as the tube wall 1 is formed on the outer circumferential surface of a tube wall 1 made of soft vinyl chloride, the inner circumferential surface of which is formed as a flat surface 2 with the same diameter in the length direction. A protrusion 3 is integrally formed, and a copper wire 4 coated with an olefin-based synthetic resin such as polyethylene is spirally installed inside the hollow spiral protrusion 3 without adhesion.
Furthermore, the length interval of the tube wall 1 to which the inner ends of both side walls of the hollow spiral protrusion portion 3 are bonded is made into a flexible tube wall portion 5 which is larger than the diameter of the coating resin layer 6 of the copper wire 4. A suction hose for vacuum cleaners made of The interior of the hollow spiral protrusion 3 is divided into upper and lower parts by a wave-shaped partition wall 9 made of soft vinyl chloride resin and having a bipolar cross section, and the outer bottom surface of the trough 9a of the partition wall 9 is integrated with the tube wall 1. An olefin synthetic resin such as polyethylene having a diameter larger than that of the resin-coated copper wire 4 is welded and placed in the central space 3c formed by the opposing surfaces of the troughs 9a and the hollow spiral protrusions 3. The reinforcing core wire 10 is arranged in a continuous spiral shape, and the peak part 9
The suction hose for a vacuum cleaner according to claim 1, wherein the pair of coated copper wires 4, 4 are arranged in a continuous spiral inside the space portions 3d, 3d on both sides formed in the spaces 3d, 3d formed in the spaces 3d, 9b. 2. A suction hose for a vacuum cleaner according to claim 1, wherein a reinforcing sheet 11 is embedded in the pipe wall 1, and is formed by integrating narrow and flat resin threads stretched in the longitudinal direction vertically and horizontally.
