<p><P>PROBLEM TO BE SOLVED: To provide a handrail structure easily executed and enabling a corner part to be formed at a lower cost. <P>SOLUTION: A curved line shaped joint material 20 is connected with both adjacent handrail core materials 10 and covered with a covering material 30 at the corner part in a handrail H. The handrail core material is formed of a hollow shape having a pair of fitting ridges 11 at both lower ends, recessed grooves 12 at an upper surface and at both side surfaces, and a hollow part 13. The joint material has a joint main body 22 having fitting ridges connected with the fitting ridges of the handrail core materials at both lower ends and connection pieces 26 protrudingly formed at both the ends and fitted in respective hollow parts 13 of the handrail core materials. The handrail core materials and the joint materials are fixed with set screws having heads stored in the recessed grooves while the connection pieces are fitted in the hollow parts of the handrail core materials, and the handrail core materials and the joint material are covered with the covering material by fitting the covering material to the fitting ridges of the handrail core materials and the joint material. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
