Description

  The present invention relates to a handrail having an information display unit such as Braille and a method for attaching the handrail.

  Conventionally, for example, in public facilities such as stations, information display units such as Braille are provided on stair railings to provide information to visually impaired persons.

  However, the conventional one uses a thin metal plate or braille stamped information display plate attached to the surface of the handrail with rivets etc. so that it does not hinder the walking motion of the handrail. There is a risk that the user may be injured due to a peeled state or a state where the end of the metal plate has jumped up. Further, there is a problem that the braille portion is worn out after being used for a long period of time, and the stamped braille information is not sufficiently transmitted. Therefore, it is necessary to replace the old information display plate that has been damaged or the like with a new information display plate.

Further, the guide component having a lid body with braille formed on the surface is incorporated into the handrail main body via a joint member, or is incorporated in a state in which the handrail main body is inserted at both ends of the guide component. A guide handrail is known (for example, see Patent Document 1).

It is preferable that the fixing screw 90 can be operated only by a tool such as a special hexagon wrench 100.

  According to the handrail having the information display portion according to the present invention configured as described above, there is no step between the display plate 70 having the information display portion 11 such as Braille and the lower surface plate 80 and the handrail body 1. Therefore, it is possible to prevent the user from hindering the operation of walking with a handrail.

  Next, an example of a procedure for attaching the handrail structure 10 to the existing handrail main body 1 will be described with reference to FIGS. 4 to 9.

  First, two places at predetermined positions of the existing handrail main body 1 are cut to form an attachment space 3 for attaching the handrail component 10 (see FIG. 4).

  Next, the spacer 27 and a plurality of fit blocks 32 restrained by the annular spring 33 are fitted on the outer surface of the insertion portion 23 of one base member 20. Next, with the hooked nut 42 in contact with the tip of the fit block 32, the fastening bolt 41 penetrating the insertion portion 23 is loosely screwed into the hooked nut 42. Thereby, the fit block 32 is temporarily fixed to the outer peripheral surface of the insertion portion 23. In this state, the fit block 32 is slidably brought into non-rotatable contact with the tapered surface 23 a of the insertion portion 23.

  Next, when the insertion bolt 23 and the fit block 32 are inserted into the opening 2 of the handrail body 1 and the tightening bolt 41 screwed to the hooked nut 42 is tightened using the hexagon wrench 45. Each fit block 32 expands and moves along the enlarged diameter side of the tapered surface 23 a of the insertion portion 23 against the elastic force of the annular spring 33, and the outer peripheral surface of each fit block 32 is the opening of the handrail body 1. 2 is in pressure contact with the inner peripheral surface. By this spreading action, the insertion portion 23 of the base member 20 is fixed in the opening 2 of the handrail body 1. A similar operation is performed to fix both base members 20 to the handrail body 1 (see FIGS. 5 and 6). In this way, by tightening the fastening bolt 41, the fit block 32 expands and moves along the tapered surface 23a of the insertion portion 23, so that the centering of the base member 20 with respect to the handrail body 1 is easy, The base member 20 can be firmly fixed to the handrail main body 1.

  Next, the flat surfaces of the connecting base portions 21 of the pair of base members 20 fixed to the handrail body 1 are in contact with each other, and the connecting hole 28a and the screw hole 28b are aligned with each other. The screws 50 are screwed into the screw holes 28b to connect and fix the base members 20 to each other (see FIG. 7). At this time, in the case where a gap is generated between the columnar portion 22 of the base member 20 and the handrail main body 1, the gap may be blocked by using spacers 27 having different thicknesses according to the gap. Therefore, it is necessary to prepare several types of spacers 27 having different thicknesses.

  Next, the insertion member 60 is inserted into the space 61 formed between the connected base member 20 and the handrail body 1 to close the space 61 (see FIG. 8). At this time, by fitting the arc ridge 63 of the insertion member 60 into the inner arc groove 21a of the base member 20, the positioning of the insertion member 60 with respect to the base member 20 is facilitated. A solid circular cross section is formed in cooperation with the insertion member 60 (see FIG. 3D).

  After the space 61 is closed by the insertion member 60, the upper surfaces of the base member 20 and the insertion member 60 are covered with the display plate 70, and the lower surfaces of the base member 20 and the insertion member 60 are covered by the lower surface plate 80.
