[0039] The reinforcing member 83 is attached to the square pipe 81 by connecting the reinforcing member mounting hole 81a and the screw hole 83a and fixing with a fixing screw 84.

[0040] The handrails 50 on both sides are attached to the wall 10 by inserting the sheath pipe 42 from the rear into the through hole 10a of the wall 10, fitting the square pipe 81 into the sheath pipe 42 from the outside, and connecting the through hole 42a, the sheath pipe mounting hole 68, and the sheath pipe mounting hole 81c and fixing them with screws.

[0041] The exterior member 90 (to be distinguished, they are referred to as exterior member 90A, exterior member 90B, and exterior member 90C) is made of a melamine decorative board having antibacterial and antiviral properties. The melamine decorative board is made by impregnating paper with a thermosetting resin (melamine resin, phenolic resin) and molding it under high temperature and pressure.

[0042] In this embodiment, the exterior member 90 is attached to the first core member 60 except for its front and rear ends by post-forming. The post-forming process involves applying an adhesive to the first core member 60, and applying heat and pressure to the exterior member 90 to mold it to the shape of the first core member 60. Details will be described later.

[0043] In addition, in this embodiment, as shown in Figure 4, when viewed from the axial direction of the first core material 60, the joint portion between the first division body 62 and the second division body 65 on the upper end side of the first core material 60 is covered with an exterior member 90, and the joint portion of the exterior member 90 is arranged at the joint portion between the first division body 62 and the second division body 65 on the lower end side of the first core material 60.

[0044] A decorative plate 91 is attached so as to cover the front ends of the first core material 60 and the second core material 80 .

[0045] Both side supports 100 (to be distinguished, they are referred to as both side supports 100A and both side supports 100B) are made of stainless steel and are formed in a stepped cylindrical shape.

[0046] Each side support 100 has an externally threaded portion 101 having an external thread formed at an upper end thereof, and an internally threaded portion 102 having an internal thread formed at a lower end thereof.

[0047] 1 to 3 and 5, the through handrail 110 as a post-formed product includes a first core material 120, a second core material 140, and an exterior member 90. In this embodiment, the through handrail 110 is set to a length of 50.7 mm, a width of 420.0 mm, and a depth of 25.2 mm.

[0048] The first core 120 is formed from water-resistant MDF (medium density fiberboard) plywood.

[0049] The first core 120 is composed of a first divided body 122 and a second divided body 125, and has a second core arrangement portion 121 in which the second core 140 is arranged.

[0050] The first partition 122 and the second partition 125 are formed by dividing an oval-shaped member that is long vertically into two in the left-right direction to have a line-symmetrical shape, and are provided with second core material positioning portion forming recesses 123, 126 that are formed as bottomed holes extending from the opposing surface to the opposite side of the opposing surface.

[0051] In this embodiment, the second-core-material-arrangement-portion-forming recesses 123, 126 are formed by cutting out a rectangular shape corresponding to the shape of the second core material 140 described later.

[0052] When the first division body 122 and the second division body 125 are assembled, the first core material 120 has an outer shape of an elongated cylinder, and the second core material arrangement portion 121 has a rectangular shape located toward the front in the front-to-rear direction.

[0053] The left and right ends of the first core 120 are formed with decorative board fixing holes 124, which are formed as bottomed holes extending from the left and right end faces toward the center.

[0054] A second core material 140 is placed in the second-core material-placement-portion-forming recesses 123, 126. In this embodiment, the second core material 140 provides strength reinforcement.

[0055] The second core material 140 is made of stainless steel and has a large diameter portion 141 formed in a rectangular column shape, a medium diameter portion 142 formed in a cylindrical shape with a smaller diameter than the large diameter portion 141 at both ends of the second core material 140 in the left-right direction, and a small diameter portion 143 formed in the medium diameter portion 142 with a cylindrical shape and a smaller diameter than the medium diameter portion 142.

[0056] In this embodiment, the large diameter portion 141 is disposed in the second core material placement portion 121 , and the medium diameter portion 142 and the small diameter portion 143 are disposed outside the second core material placement portion 121 .

[0057] The handrail 110 is attached to both side posts 100 via fixing hardware 160 as mounting members.

[0058] The fixing hardware 160 (when distinguishing between them, they are referred to as fixing hardware 160A and fixing hardware 160B) is made of stainless steel and formed into a cylindrical shape.

[0059] The fixing hardware 160 is provided with an axle support hole 161 formed as a bottomed hole extending from the end face of the fixing hardware 160 facing the handrail 110 to the opposite end face, and a screw hole 162 that is perpendicular to the axle support hole 161 and connects the axle support hole 161 to the outer peripheral surface 160a of the fixing hardware 160.

[0060] The fixing hardware 160 is provided with a post mounting screw hole 163 which is perpendicular to the screw hole 162 and is formed as a bottomed screw hole extending from one outer peripheral surface 160a of the fixing hardware 160 to the other outer peripheral surface 160a.

[0061] The fixing hardware 160 is attached to both side supports 100 by screwing the male threaded portions 101 of the both side supports 100 into the support mounting screw holes 163 .

[0062] The post mounting holes 67, 81b, 81d, and 69 are connected to each other, the post mounting holes 100 on both sides are inserted from above, and the female threaded portions 102 are screwed into the screws, thereby attaching the side posts 100 to the side handrails 50.

[0063] The medium diameter section 142 and the small diameter section 143 of the second core material 140 of the through handrail 110 are inserted into the shaft support hole 161 of the fixing hardware 160, the screw hole 162 and the small diameter section 143 are connected, and the through handrail 110 is fixed with a screw 144, so that the through handrail 110 is attached to both side supports 100 so that it can rotate around an axis in the left-right direction.

[0064] In addition, in this embodiment, as shown in Figure 5, when viewed from the axial direction of the first core material 120, the joint portion between the first division body 122 and the second division body 125 on the upper end side of the first core material 120 is covered with an exterior member 90C, and the joint portion of the exterior member 90B is arranged at the joint portion between the first division body 122 and the second division body 125 on the lower end side of the first core material 120.

[0065] Decorative panels 92 are attached so as to cover the left and right ends of the first core material 120 and the second core material 140 .

[0066] We will now explain the manufacturing direction of both side handrails 50 and the through handrail 110 as post-formed products. We will now explain the case of manufacturing both side handrails 50. The through handrail 110 is similar to both side handrails 50, so its explanation will be omitted.

[0067] As shown in Figure 6, the first divided body 62, the second divided body 65, and the jig 200 are set on a flat surface F such as a surface plate before the second core material arrangement portion forming recesses 63, 66 are formed on the flat surface F.

[0068] More specifically, in this embodiment, the first divided body 62, the second divided body 65, and the jig 200 are set so as to be parallel to one another. The jig 200 is formed in a long rectangular prism shape, and its shape is set after measuring the lengths of the outer circumferential surfaces of the exterior member 90 and the first core material 60 as viewed in the axial direction of the first core material 60, and accurately defines the distance between the first divided body 62 and the second divided body 65.

[0069] A temporary fixing tape 201 is applied to the entire surface (top surface) of the first divided body 62, the second divided body 65, and the jig 200 opposite the flat surface F, and the first divided body 62, the second divided body 65, and the jig 200 form an integrated semi-finished unit 210.

[0070] The temporary fixing tape 201 maintains the set state of the first divided body 62, the second divided body 65, and the jig 200 that constitute the semi-finished unit 210. In other words, it maintains the horizontality of the first divided body 62, the second divided body 65, and the jig 200, and accurately maintains the distance between the first divided body 62 and the second divided body 65.

[0071] The above is the first step.

[0072] Next, as an example, as shown in Figure 7, an exterior member 90 is placed on a flat surface F, and an adhesive is used to bond the exterior member 90 to a portion of the first divided body 62 and the second divided body 65, which constitute the semi-finished unit 210, before the second core material arrangement portion forming recesses 63, 66 are formed, on the side opposite (below) the temporary fixing tape 201.

[0073] More specifically, the surfaces of the first divisional body 62 and the second divisional body 65 that come into contact with the exterior member 90 are bonded to the exterior member 90. This is the second step.

[0074] Next, as shown in FIG. 8, the exterior member 90 at the end portions (the right end portion for the first divided body 62 and the left end portion for the second divided body 65) of the first divided body 62 and the second divided body 65 opposite the jig 200 before the second-core-arrangement-part forming recesses 63, 66 are formed as viewed from the axial direction of the first core member 60 is heated and bent so that the surface temperature is 170 to 200 degrees, and the exterior member 90 is bonded to the first divided body 62 and the second divided body 65 via an adhesive, and the excess of the exterior member 90 is trimmed. It is also possible to cut the exterior member 90 in advance to a size that does not leave any excess. This is the third step.

[0075] 9, second core material placement portion forming recesses 63, 66 are formed in the first divided body 62 and the second divided body 65, and the temporary fixing tape 201 and the jig 200 are removed as shown in Fig. 10. This completes the fourth process.

[0076] Furthermore, as shown in FIG. 11, the portion of the exterior member 90 where the jig 200 was placed and its surroundings are heated so that the surface temperature is 170 to 200 degrees, and the ends of the first division body 62 and the second division body 65 opposite the side where the jig 200 was placed (the right end of the first division body 62 and the left end of the second division body 65) are brought close to each other when viewed from the axial direction of the first core material 60, and the first division body 62 and the second division body 65 and the exterior member 90, and the opposing surfaces of the first division body 62 and the second division body 65 are bonded together using an adhesive.
