  The lower end portion of the shaft body 4 is fixed to a gear-type shaft body fastener 6 with bolts 7, and the upper end portion is fixed to the upper fastener 8 with bolts 9. In addition, a parallel pin (not shown) for preventing over-rotation and ensuring safety is inserted into the shaft body 4.

  A pair of linear bushes 10 a and 10 b are provided between the outer cylinder portion 3 and the shaft body 4 with the linear bush spacer 11 interposed therebetween. The linear bushes 10 a and 10 b are cylindrical members that slide linearly on the shaft body 4 in the axial direction of the shaft body 4, and have a structure that does not rotate around the shaft body 4. As the linear bush, a slide bush, a slide bearing, or the like is preferably used. For example, a product name linear bush manufactured by THK Co., Ltd. can be used.

  The linear bush spacer 11 is provided between the pair of linear bushes 10a and 10b so that the linear bushes 10a and 10b are positioned at both inner end portions of the outer cylinder portion 3, and thereby, the handrail portion 2 is vertically moved. The vertical movement of the outer cylinder portion 3 when the force is applied can be further smoothed. As the linear bush spacer 11, any linear bush 10a, 10b may be used as long as the linear bush 10a, 10b can be disposed at both inner end portions of the outer cylindrical portion 3. For example, a metallic or resin cylindrical member can be used.

  The number of linear bushes provided between the outer cylinder portion 3 and the shaft body 4 is not limited to the above example, and can be appropriately selected according to the length of the outer cylinder portion 3 and the shaft body 4.

  Linear bush covers 12a and 12b are provided between the linear bushes 10a and 10b and the outer cylinder portion 3 to prevent rattling. As the linear bush covers 12a and 12b, a metal or resin cylindrical body that can be disposed between the linear bushes 10a and 10b and the outer cylindrical portion 3 without being fixed thereto can be used.

  A rotation receiving member 13 is provided between the linear bushes 10a and 10b and the outer cylinder portion 3 and above the linear bush cover 12b to prevent over-rotation and ensure safety.

  Between the linear bushes 10 a and 10 b and the outer cylinder portion 3, an outer cylinder side fastener 14 fitted to the shaft body fastener 6 is formed on the inner wall of the outer cylinder portion 3 at the lower end portion of the outer cylinder portion 3. It is fixed. The shaft body retainer 6 and the outer tube side retainer 14 fix the rotation angle of the handrail portion 2 in a stepwise manner by fitting each other, and constitute a mechanism for controlling the rotation angle of the handrail portion 2. Yes.

  As the shaft body fastener 6, for example, a gear-type fastener shown in FIG. 4 can be used, and as the outer cylinder side fastener 14, for example, a gear-type fastener shown in FIG. 3 can be used. it can. By using gear-type fasteners as the shaft body fastener 6 and the outer cylinder side fastener 14, these meshing surfaces can be increased, so that rattling of the outer cylinder portion 3 is minimized. Can do.

  In the illustrated pair of gear-type fasteners 6 and 14, the gear teeth are formed at a 45 ° pitch, so that the rotation angle θ of the handrail portion 2 can be rotated by 45 °. Therefore, for example, when the horizontally-rotating handrail of the present invention is installed on the toilet bowl in the toilet room, for example, as shown in FIG. 5, the back of the person seated on the toilet bowl 30 is the corner of the toilet room. When the seating toilet 30 is provided so as to face the seat 31 and the horizontal turning type handrail 1 of the present invention is attached to the frame 15 so as to protrude from the back side of the seating toilet to the front side on both sides of the seating toilet 30. In addition, the handrail part 2 is positioned along the wall surface 32 extending from the corner part 31 of the toilet room (position indicated by the solid line, rotation angle θ = 0 °) and extending in the depth direction of the seat 30. It is possible to rotate and fix in two stages of the position shown by (3) and the rotation angle θ = 45 °.

  In addition, this invention includes the handrail 20 for sitting toilets which the horizontal rotation type handrail 1 is attached to the frame 15 in this way, and is installed with respect to a sitting toilet. A backrest 16 may be provided on the handrail 20 for a sitting toilet as required.

  As a method of using the horizontal rotation type handrail 1 of this embodiment, the handrail portion 2 is disengaged from the outer cylinder side retainer 14 by pushing the handrail portion 2 upward, and the handrail portion 2 is a shaft body. Horizontal rotation is possible with 4 as the central axis. In this state, when a force is applied to the handrail portion 2 in the horizontal direction, the handrail portion 2 smoothly rotates to the next rotation angle at which the rotation is fixed. When the next rotation angle at which the rotation is fixed is reached, the handrail portion 2 is lowered by the weight of the handrail portion 2, the shaft body fastener 6 and the outer tube side fastener 14 are fitted, and the rotation angle is stopped. In this case, the slidability of the outer cylinder portion 3 to which the handrail portion 2 is fixed is not impaired by moving the handrail portion 2 upward.

  The rotating handrail of the present invention can take various forms. For example, in the horizontal rotation type handrail 1 of the above-described embodiment, the rotation angle to be fixed can be appropriately set by changing the gear tooth pitch of the shaft body retainer 6 and the outer tube side retainer 14. The number of stages to be fixed can also be set as appropriate. For example, the handrail portion 2 may be fixed in seven stages from a rotation angle of 0 ° to 15 ° in increments of 90 °. From the viewpoint of ease of use of the handrail 2, it is preferable that the rotation angle of the handrail 2 can be fixed in two stages of 0 ° to 45 °.

  Further, in the present invention, as a mechanism for controlling the turning angle of the handrail portion that enables the handrail portion 2 to be rotated stepwise, the handrail portion 2 is made of an elastic member that urges the outer tube portion 3 upward. When the handrail part 2 is pushed up or down, the action of the elastic member is released and the outer cylinder part 3 naturally falls, and the shaft body fastener 6 and the outer cylinder side fastener 14 are fitted. It is also possible to stop the rotation and push the handrail portion 2 up or down again so that the elastic member acts to enable the handrail portion 2 to turn.

  The horizontal rotation type handrail 1 of the present invention can be used for a handrail 20 for a sitting toilet as shown in FIG. As shown in FIG. 5, when the frame 15 is configured for the sitting toilet 30 installed in the corner 31 of the toilet room, as shown in FIG. 6, the handrail portion 2 has at least the depth of the sitting toilet 30. A position extending in the direction (position shown by a solid line, rotation angle θ = 0 °) and a position along a wall surface 32 extending from the corner 31 of the toilet room (position indicated by a broken line, rotation angle θ = 45 °) ), The handrail portion 2 can be used as a handrail to be used when sitting or standing on the sitting toilet 30 at a rotation angle θ = 0 °, and the handrail portion 2 at a rotation angle θ = 45 °. Can be used as a handrail used when moving between the entrance of the toilet room and the sitting toilet 30. At this time, even if the user of the horizontal turning type handrail 1 is a cared person, the turning angle of the handrail portion 2 can be easily changed smoothly.

The handrail 20 for a sitting toilet according to the present invention is not limited to the case where it is installed in the corner 31 of the toilet room, but may be attached to the sitting toilet 30 installed on the front surface of the flat wall surface 32 as shown in FIG. good.
