<p>The present invention relates to an electronic walking cane for the visually impaired which is adapted with an RFID reader to wirelessly detect RFID tags which are positioned as guides along footpaths with Braille blocks having embedded RFID tags. The present electronic walking cane comprises: a handle which is in the shape of a hollow tube within which a circuit board is installed; a plurality of connectors each having a tapering, hollow tubular structure which are sequentially mounted into each other such that the lower end of one connector is inserted into the upper end of the next connector; a coiled cable, consisting of a plurality of coated wires, with one end connected to said handle and the other end connected to the tip of the lowest of said plurality of connectors; an elastic member for preventing the twisting of said coiled cable, is inserted into the medial section of said coiled cable, with one end connected to said handle and the other end connected to the tip of the lowest of said plurality of connectors; a first and a second fastener which respectively fasten said handle to each of said plurality of connectors, and said coiled cable to said elastic member; and an insulating material having a cylindrical structure installed onto the inner surface of said plurality of connectors, which reduces noises which occur when said elastic member, said coiled cable and said plurality of connectors rub against each other with movement of said walking cane.</p> |
