As shown in FIGS. 11 and 12, the cap member 37 is connected between two disk parts 37a and 37b and both disk parts 37a and 37b inserted into the two holes 31 and 32, and is slit. It is formed of a rectangular block-shaped insertion portion 37c inserted into 33, and is formed of, for example, a synthetic rubber member.

  The rotating shaft 40 is formed of a stainless steel member. As shown in FIGS. 11 and 12, flat surfaces 41 are provided on both sides of the intermediate portion, and a slit along the axial direction is provided at the center of both ends. A portion 42 is formed. As described above, the rotary shaft 40 formed in this manner is attached to the slit portion 42 at one end of the handrail body 20 in a state of being attached through the support member 10, the bracket 30, the handrail body 20, and the reinforcing member 25. A spring member, for example, a spiral spring 43, which applies a restoring elasticity in the direction in which the handrail body 20 is lifted when the handrail descends is engaged, and a brake member, for example, oil viscosity for braking the rotating shaft 40 is used for the slit portion 42 at the other end. Thus, a disk damper 44 that generates torque is engaged.

  On the other hand, as shown in FIGS. 6, 11 and 12, the support member 10 includes a rectangular base 11 and a pair of support pieces 12 facing each other in parallel with respect to the central portion of the base 11. It is formed of an aluminum extruded shape having a substantially π-shaped cross section. In this case, mounting holes 13 are formed at four locations on the upper and lower ends of the base 11, and a locking claw piece for locking a cover member 60 described later is provided on the surface side of both side edges, that is, on the support piece 12 side. 14 is projected (see FIG. 6).

  The support pieces 12 have a thick portion 15 formed from the intermediate portion to the base end portion side, and a thin portion 16 formed from the intermediate portion to the distal end side. A cover member 60 is provided at the distal end portion. A locking step 17 for locking is formed. A through hole 10 a into which the rotating shaft 40 is inserted is formed in the thick portion 15 of the support piece 12.

  Further, a position restricting member 50 for maintaining the horizontal position when the handrail 20 is used and the retracted position when not in use is attached between the support pieces 12 in the base 11 of the support member 10. As shown in FIGS. 5, 8, 10, 11, and 12, the position restricting member 50 includes a substantially rectangular position restricting piece 51 positioned on the surface of the base 11 between the support pieces 12 a, and this position.

  In this case, a fitting groove 53 into which a magnetic plate 36 such as a steel plate that can be attracted to the magnet 35 attached to the bracket 30 can be fitted is provided on the upper side of the position regulating piece 51. The fitting groove 53 is formed by a pair of guide ridges 53a having an inverted L-shaped cross section that confront each other. The magnetic plate 36 is fitted and fixed in the fitting groove 53 formed in this way. Thereby, when the handrail body 20 stands up from the horizontal state, the magnet 35 and the magnetic plate 36 fixed to the bracket 30 are attracted to maintain the retracted position of the handrail body 20.

  Further, a flat bulge portion 54 is formed on the lower side of the position restricting piece 51 so as to contact the end surface of the bracket 30 and maintain the horizontal position of the handrail body 20 when the handrail body 20 is placed in the horizontal position. Yes. A plurality of reinforcing ribs 55 that are in parallel with each other and that are in contact with the base surface are provided on the back surface side of the flat bulging portion 54. Thus, by providing the reinforcing rib 55 on the back surface side of the flat bulging portion 54, the pressure resistance of the flat bulging portion 54 with which the bracket 30 abuts at the use position of the handrail 20 can be increased.

  In addition, a slight gap is provided between the fitting groove 53 and the flat bulging portion 54 in the position restricting piece 51 so that the upper end corner portion 38 of the bracket 30 that rotates as the handrail 20 rotates does not interfere. A concave arcuate portion 56 that can be rotated is formed. That is, a concave arc portion 56 having a slightly larger curvature than the rotation trajectory of the upper end corner portion 38 is formed (see FIGS. 4, 5, and 7 to 11). In this case, the gap s between the concave arc portion 56 and the locus of the upper end corner portion 38 of the bracket 30 is set to a gap where the child's finger does not enter, for example, 4 mm or less. In other words, the gap s between the curvature surface of the concave arc portion 56 and the rotation trajectory of the upper end corner portion 38 of the bracket 30 is set to be within a range in which the child's finger cannot enter (4 mm or less). 4 and 5, the child's finger does not enter the gap s between the concave arc portion 56 and the upper end corner portion 38 of the bracket 30 at the horizontal position of the handrail 20 in use shown in FIGS. 9 and FIG. 10, the finger of the child does not enter the gap s between the concave arc portion 56 and the upper end corner portion 38 of the bracket 30 even at the standing position (storage position) of the handrail 20 when not in use.

  In a state where the position regulating member 50 formed as described above is attached between the two support pieces 12 of the support member 10, cover members 60 are respectively attached to both sides of the support member 10, and the spiral spring 43 and the disk damper 44.

  In this case, the cover member 60 includes one outward projecting portion of the base 11 of the support member 10, a substantially triangular top plate portion 61 and a bottom plate portion 62 that close the upper end and lower end of the support piece 12, and the top plate portion 61. And an inclined side plate portion 63 that connects the bottom plate portion 62 and is formed of a synthetic resin member such as ABS resin.

  In this case, the inclined side plate portion 63 has a locking claw 64 that engages with the locking claw piece 14 of the support member 10 at one end and a forked portion that engages with the locking step portion 17 of the support member 10 at the other end. The outer surface of the locking groove 65 is formed so as to be positioned on the same plane as the opposite side surface of the support piece 12 when locked to the support member 10. . Note that the locking claws 64 are provided at three locations, the upper and lower end portions and the intermediate portion of the inclined side plate portion 63. Further, the top plate portion 61 has an upper surface located on the same plane as the upper surface of the horizontal locking piece 52 of the position regulating member 50, and has a hanging piece 61a that covers the upper end portion of the support piece 12 (see FIG. 2). Note that the end of the hanging piece 61 a is formed to bulge at the upper end of the outer surface of the locking groove 65. Further, the bottom plate portion 62 has an upright piece 62 a that covers the lower end portion of the support piece 12, and an end portion of the upright piece 62 a is bulged at the lower end portion of the outer surface of the locking groove portion 65.

  The cover member 60 formed as described above is attached to both sides of the support member 10 via cover receivers 70 fixed to the outer side surface of the support piece 12 of the support member 10 by a double-sided adhesive tape or the like. In this case, the cover receiver 70 includes an inclined receiving piece 71 having an inclination angle along the inclined surface of the inclined side plate portion 63 of the cover member 60, a pair of leg pieces 72 bent at both ends of the inclined receiving piece 71, The leg piece 72 is formed of, for example, an aluminum extruded profile having a substantially hat-shaped cross section including an attachment piece 73 bent outward from the tip of both leg pieces 72. The cover receiver 70 formed in this way is fixed to the outer side surface of the support piece 12 of the support member 10 on the back surface of the mounting piece 73 via a double-sided adhesive or the like.

  Next, the assembly procedure of the handrail H and the attachment procedure to the wall surface 1 will be described. First, the reinforcing member 25 and the contact plate member 28 are inserted into the upper and lower base end portions 21 and 22 of the handrail body 20, respectively, and the upper and lower base end portions 21 and 22 of the handrail body 20 are inserted into the two holes 31, In the state where the through hole 30a provided in the bracket 30 and the fitting hole 25a provided in the reinforcing member 25 are matched, the upper and lower side bases of the bracket 30 and the handrail 20 are fixed by the fixing screw 26. The end portions 21 and 22 are fixed.

  Next, a bracket 30 that holds and holds the handrail body 20 is inserted between the two support pieces 12 of the support member 10 to which the position restricting member 50 is attached at the upper part between the two support pieces 12, and the through hole 10 a of the support member 10. And the through hole 30a of the bracket 30 are matched. Next, the rotating shaft 40 is inserted into the through hole 10 a of the support member 10, the through hole 30 a of the bracket 30, and the insertion hole 25 a of the reinforcing member 25. In this state, the push screw 27 is screwed into the fixing screw hole 25 b of the reinforcing member 25, and the push screw 27 is pressed against the flat surface 41 of the rotary shaft 40 to fix the rotary shaft 40 and the bracket 30. Thereafter, the cap member 37 is attached to the two holes 31 and 32 and the slit 33 on the small edge side of the bracket 30.

  Next, the spiral spring 43 and the disk damper 44 are respectively attached to the slit portions 42 on the protruding side of the rotating shaft 40 fixed to the bracket 30 as described above. At this time, if there is a gap between the bracket 30 and the two support pieces 12, a washer 45 may be interposed.

  The support member 10 is shipped with the handrail body 20 and the bracket 30 assembled to the support member 10. After the support member 10 is attached to the side wall 1 on the side of the toilet 2 by an attachment screw (not shown), the support member 10 is attached. Cover members 60 are attached to both sides of the cover.

  The handrail H according to the present invention configured as described above is configured so that the rotating shaft 40 passes through the bracket 30 with the upper-side base end portion 21 of the handrail body 20 being inserted into the hole 31 of the bracket 30. Since the handrail body 20 is fixed, the bracket 30 and the handrail body 20 can be firmly connected. Therefore, even when a large load is applied to the handrail body 20 in the use state, there is no worry about the rattling of the handrail body 20. Further, in the use state, that is, in the state where the handrail body 20 is in the horizontal position, the base end side portion of the bracket 30 abuts on the flat bulged portion 54 of the position regulating member 50 having the plurality of reinforcing ribs 55 on the back surface. Even when a large load is applied to the rail 20, the horizontal bulge portion 54 can stably maintain the horizontal posture of the handrail body 20 and can prevent deformation by imparting strength to the load applied to the handrail body 20 ( (See FIGS. 4 and 5).

  Further, in the unused state, that is, in the retracted state in which the handrail body 20 stands vertically, the upper portion 24a of the handrail body 20 and the upper side base end portion 21 extending to the end portion of the upper portion 24a are close to the wall surface 1 in parallel. The space between the wall 1 and the wall 1 can be reduced and stored. In this retracted state, the magnet 35 and the magnetic plate 36 fixed to the bracket 30 are attracted to maintain the retracted position of the handrail 20 (see FIGS. 9 and 10).

  Further, since the gap s between the upper end corner portion 38 of the bracket 30 and the concave arc portion 56 of the position restricting member 50 attached to the support member 10 is set to a gap in which a child's finger does not enter, for example, 4 mm or less, a handrail. When the body 20 is rotated from the use position to the storage position or from the storage position to the use position, there is no concern that the user will be pinched by the user.

  Furthermore, since the upper and lower openings and the side openings on both sides of the base 11 of the support member 10 and the outer side of the support piece 12 are covered with the cover member 60, the protruding portion of the rotating shaft 40 pivotally attached to the support piece 12. The spiral spring 43 that urges the handrail body 20 to be restored in the lifting direction, the disk damper 44 that brakes the rotation of the rotary shaft 40, etc. can be blinded from the outside. In this case, the inclined side plate portion 63 of the cover member 60 is attached to the inclined receiving piece 71 of the cover receiver 70 formed of an extruded aluminum member having a substantially hat-shaped cross section that is fixed to the outer surface of the supporting piece 12 of the supporting member 10. By supporting the contact, deformation of the cover member 60 made of synthetic resin can be prevented.

  In the above-described embodiment, the structure in which the handrail body 20 is formed in a substantially U shape and the upper and lower side base end portions 21 and 22 are fixedly held by the bracket 30 is described.
