Title:
EXTENSIBLE TUBE AND ELECTRIC VACUUM CLEANER USING THE SAME
Document Type and Number:
Japanese Patent JP3655131
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide an extensible tube of an electric vacuum cleaner capable of facilitating the assembling work of a connection pin to be connected to a suction hose and a suction opening body.
SOLUTION: A pair of conductive metallic bars 57 are arranged in a bridge body 56 of an extensible extension pipe 30 constituted of an internal pipe 50 formed of an external pipe 40 provided with a feeding rail 47 along the axial direction on the outer peripheral wall face of the external pipe body 41, an internal pipe body 51 transferably inserted in the external pipe body 41, and a bridge body 56 the basal part of which is fixedly fitted to one end side of the internal pipe body 51. One end side of the conductive metallic bar 57 is used as a connection pin 57a and a sliding piece 57b sliding on the feeding rail 47 is installed at the other end side. In this way, the connection process of the connection pin is eliminated to facilitate the assembling work and a conductive fault resulting from defective connection is prevented.
