Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective configuration diagram in a state where an armrest 2 is attached to a wall surface W in a toilet room. Such an armrest 2 is attached to a side of a toilet 1, and an arm is placed on the armrest 2 while sitting on the toilet 1. The toilet 1 is configured to be used in a comfortable posture when placed thereon, and the armrest 2 is configured to be rotatable from a horizontal position to an upright position rising from the horizontal position to the wall surface W side.

FIG. 2 shows a side view of the armrest 2, and FIG. 3 shows a plan view thereof. The armrest 2 has an arm fixing portion 4 fixed to the tip of a pipe-shaped arm 3. The arm fixing portion 4 has a structure as shown in a perspective view of FIG. Bend 90 ° to the rear side from the left and right projecting pieces 4b and 4b
c is formed integrally, the horizontal cross-sectional shape is formed in a U-shape, and a rotating shaft 5 is provided horizontally between the left projecting piece 4b and the right projecting piece 4c. It is fixed to the left protruding piece 4b and the right protruding piece 4c by a caulking portion 5a, and a horizontal stopper 6 parallel to the rotation shaft 5 has the left protruding piece 4b and the right protruding piece. The stopper 6 is provided in a bridging manner between 4c, and the stopper 6 is disposed on the rear side of the rotating shaft 5.

On the other hand, a pedestal 13 is fixed to the wall surface W of the toilet in advance, and a mounting bracket 7 shown in a perspective view of FIG. The mounting bracket 7 of FIG. 5 is formed integrally with an upper surface piece 7b protruding rearward on an upper surface side of a curved piece 7a.
A lower surface piece 7c is formed integrally with the lower surface side of the curved piece 7a so as to protrude rearward, and is formed in a U-shape in a vertical cross section.
A cylindrical tubular portion 8 is fixed horizontally in the inside of the portion reaching a, and a cylindrical bush 9 is fitted into the tubular portion 8.

On the rear side of the cylindrical portion 8, a resistor 10 is vertically attached between the upper piece 7b and the lower piece 7c. The resistor 10 is formed of spring steel and has an upper end. The upper moderation concave part 10a which dented to the back side is formed in the side,
A lower moderation recess 10b, which is also recessed, is formed on the lower end side. The upper surface piece 7b and the lower surface piece 7
c, two screw holes 7 each penetrating vertically
d and 7d are formed. The fixing screws 11 and 11 are inserted from above into the screw holes 7d and 7d, and the nut 12 is fastened to the fixing screw 11 from below,
The mounting bracket 7 is configured to be fixed to the pedestal 13 via fixing screws 11.

The mounting bracket 7 is previously fixed to the pedestal 13 via fixing screws 11, 11, and the arm fixing section 4 can be mounted on the mounting bracket 7. That is, with the rotating shaft 5 removed, the left and right projecting pieces 4b and 4c of the arm fixing portion 4 are arranged on both left and right outer sides of the mounting bracket 7 to form a gap in front of the curved piece 7a of the mounting bracket. Then, the connecting piece 4a of the arm fixing piece 4 is arranged, and in this state, the rotating shaft 5 is inserted through the bush 9 from the outside, and the rotating shaft 5
Is crimped at both ends to form a caulking portion 5a, whereby the arm fixing portion 4 can be connected to the mounting bracket 7 via the rotating shaft 5, and the rotating shaft 5 can rotate inside the bush 9. As shown in FIG. 2, the arm 3 can be turned from a horizontal position to a standing position by turning the arm fixing portion 4 in the vertical direction. If the stopper 6 is configured to be pressed by the resistor 10 and slidably contact with the resistor 10 when the stopper 6 rotates, the stopper 6
Can be prevented from suddenly turning by being pressed against the resistor 10 so that the arm 3 can be properly prevented from suddenly turning and falling downward. .

Since the upper concave portion 10a is formed in a concave shape at the upper end of the resistor 10, the stopper 6 fits into the upper concave portion 10a when the arm 3 is in a horizontal state. When the arm 3 is in the horizontal state, the stopper 6 is in contact with the lower surface of the upper surface piece 7b of the mounting bracket 7, so that the arm 3 is favorably held in the horizontal state. Further, when the arm 3 is turned to the upright state, the stopper 6 fits into the lower moderation concave portion 10b of the resistor 10, so that the arm 3 can be favorably held in the upright state. The resistor 10
The shape and thickness of the stopper 6 can be changed so that an appropriate resistance can be obtained when the stopper 6 is slid.

In this embodiment, when the arm fixing portion 4 is connected to the mounting member 7, the left and right side surfaces of the mounting member 7 are surrounded by the left and right protruding pieces 4b and 4c of the arm fixing portion 4, and the inside of the arm fixing portion 4 is enclosed. Since the cylindrical portion 8 and the resistor 10 are concealed,
From the outside, it has a neat appearance and is compact. In addition, since the sliding contact portion between the stopper 6 and the resistor 10 is entirely hidden inside, there is no danger of the hand being pinched during rotation. Further, the mounting bracket 7 and the arm fixing portion 4 can be easily formed by sheet metal, and can be manufactured at a low cost. Further, since the rotating shaft 5 is disposed horizontally in the cylindrical portion 8 with the bush 9 interposed therebetween, the rotating shaft 5 is stable in strength, and even if the diameter of the rotating shaft 5 is reduced, stable strength can be obtained. You can do it.

According to the present invention, there is provided a support structure for connecting an arm fixing portion at an end of an arm to a mounting bracket fixed to a wall surface to rotatably support the arm from a horizontal position to a standing position. A substantially horizontal cylindrical portion is provided in the mounting bracket, and the arm fixing portion abuts on a rotating shaft inserted into the cylindrical portion and an inner wall of the mounting bracket at least in the horizontal position. A stopper capable of holding the arm horizontally is provided so that the rotating shaft is inserted through the cylindrical part of the mounting bracket fixed to the wall, and the arm fixing part is rotatably connected to the mounting bracket. This has the effect that the armrest can be favorably held in the horizontal position via the stopper.

[0012] Further, a resistor is provided in the mounting bracket, the stopper being slidably pressed in a pressing manner when the arm is turned, so that the resistor is provided in the mounting bracket. Is in sliding contact with the resistor in a pressing manner, preventing abrupt rotation of the arm, and since the stopper and the resistor are concealed inside the mounting bracket, no hand is caught,
