<p><P>PROBLEM TO BE SOLVED: To provide a safe and high-designability handrail allowing firm fixing of leg parts to struts with easy work when performing height adjustment. <P>SOLUTION: This handrail includes height adjustment means 7 fixing the leg parts 42 to the struts 3 in which the leg parts 42 of a handrail body 4 are fitted at vertical optional positions and adjusting the height of a grip part. The height adjustment means 7 includes: a tube member 5 having both opened ends, formed with a male screw 52 on the inner circumferential face, and fitted on the strut 3; and a positioning member 6 fitted on the leg part 42 outer circumferential face in a plurality of parts in the vertical direction by recess/projection fitting. The inner circumferential face of an end part of the strut 3 is formed with an annular projecting stripe part 32c on which the lower end of the positioning member 6 abuts to restrict movement of the positioning member 6 toward the strut 3. The outer circumferential face of the end part (a connection member 32) of the strut 3 is formed with a female screw 32d into which the male screw 52 of the tube member 5 is screwed. An annular extension part 51 on which the upper end of the positioning member 6 abuts to restrict movement of the positioning member 6 toward the leg part 42 is formed around an upper end side opening of the tube member 5. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
