[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 6 to 9, flip-up handrails are generally used by being attached to walls of bathrooms, toilets and the like. The flip-up type handrail is a type of handrail that is flipped up so as not to get in the way when it is not used. As the flip-up type handrail, for example, as shown in FIGS. 6 and 7, there is a ring-shaped type rail whose main body is a flat elliptical shape. This ring-shaped flip-up handrail 8 has a ring-shaped main body 81, a locking piece 82 provided at one end thereof, an engagement hole 820 provided substantially at the center thereof, and an engagement hole 820 engaged with the engagement hole 820. Rotating pin 83

It has a fixing plate 71 for fixing 4 and an L-shaped locking member 85 attached to a lower end corner portion of the mounting plate 84. Further, the fixing plate 71 and the mounting plate 84 are integrally fixed on the wall 7 of the bathroom, toilet, or the like.

When the flip-up handrail 8 is not used, it is stored as follows. That is, as shown in FIG. 6, the one end portion 811 of the ring-shaped main body 81 is first lifted. Then, the sliding curved portion 812 on the other end side is slid on the fixed plate 71 in the arrow direction. At this time, the locking piece 82 rotates around the rotation pin 83. As a result, as shown in FIG.
The flip-up handrail 8 can be stored in a state of being adjacent to the wall surface 7 with one end portion 811 facing upward and the sliding curved portion 812 facing downward.

On the other hand, as another mode of the flip-up type handrail, there is a semicircular U-shaped type as shown in FIGS. 8 and 9, for example. This U-shaped type has a U-shaped main body 91 and an elongated hole-shaped engaging hole 92 provided at one end thereof.
And a rotation pin 93 that engages with this. Further, the handrail has a key-like locking member 94 for fixing the rotating pin 93.
And an elastic locking portion 95 provided at the end portion 912 of the U-shaped main body 91 and a rod portion 96. In addition, the key-like lock 9
4 is fixed to the wall 7.

When the flip-up handrail 9 is not used, the curved portion 911 of the U-shaped main body 91 is lifted up, and the flip-up handrail 9 is rotated about 90 degrees about the turning pin 93 as an axis, as shown in FIG. Rotate. At this time, the upper end 91

However, the above-mentioned conventional technique has the following problems. That is, when the flip-up handrail 8 is stored, as shown in FIG. 7, the flat portion 813 is merely held with the L-shaped engaging member 85 in contact with the flat portion 813. On the other hand, in the latter flip-up type handrail 9, the end portion 912 is only engaged and held in the recess 940 of the key-like locking member 94. Therefore, the flip-up type handrails 8 and 9 are both unstable when they are stored, and are unstable. The present invention has been made in view of such conventional problems, and an object thereof is to provide a flip-up type handrail which is relatively simple in structure and storage and can be used in a stable state.
