The present invention relates to a movable handrail that can be moved to provide high safety.

[Conventional technology]

As shown in Figure 2, a conventional movable handrail with support rods that can be retracted to a storage position along a wall when not in use, such as when a handicapped person enters or exits, has a support rod bent into an inverted U-shape when viewed from the side. 1, bracket 2
fixed to a rotating shaft 3 that is horizontally rotatably supported on the
It has been proposed that the rotation is regulated by a stopper 5 whose engagement/disengagement operation is controlled by an operating lever 4 attached to the support rod 1.

[Problem that the invention seeks to solve]

However, when such a handrail is used as a handrail for a handicapped person, if the stopper 5 should come off when the handicapped person's whole weight is placed on the support rod 1, the support rod 1 will swing from side to side and become extremely This can lead to a dangerous situation, and it also tends to cause malfunctions such as gripping the operating lever 4 at the same time when trying to support the support rod 1, and the safety is not only still insufficient. Furthermore, since the operating lever 4 is located relatively far from the base end of the support rod 1, it requires more force than necessary to engage and disengage the stopper 5, making it inconvenient to operate. It was hot.

The present invention has been made in order to solve the above-mentioned problem of conventional movable handrails, which are still insufficient in safety.

[Means for solving problems]

According to the present invention, the above-mentioned problem is solved by mounting the handrail main body vertically and horizontally rotatably on a bracket fixed to a wall surface, forming a locking part at the base end of the handrail main body, and attaching the handrail main body to the bracket. In this case, the locking part of the handrail main body engages with the handrail main body's own weight to prevent horizontal rotation of the handrail main body, and also releases the engagement with the locking part as the handrail main body rotates upward vertically. This is achieved by providing a movable handrail characterized by forming a locked portion.

[Effect]

The above-mentioned movable handrail allows the main body of the handrail to be horizontally rotated on a bracket that is fixed to the wall surface, so that the main body of the handrail can be moved to the storage position when not in use, and when in use. In order to prevent the handrail main body from horizontally rotating accidentally, the locking part of the handrail main body and the locked part of the bracket are engaged using the handrail main body's own weight, increasing its safety, and moving vertically upward of the handrail main body. As the locking section rotates, the locking section and the locked section are disengaged from each other, thereby improving the operability of the locking section.

On the other hand, both sides of the central portion of the bracket 2 are bent toward the vertical member 8 so as to sandwich the vertical member 8 from the outside to form a locked portion 9.

Further, the upper and lower parts of the bracket 2 are bent in the same direction as the locked portion 9 to form receiving surfaces 2a and 2b, and horizontal shaft portions 10a are provided at appropriate positions on the upper portions of the receiving surfaces 2a and 2b. The formed cross-shaped shaft 10 is mounted so as to be horizontally rotatable, and the vertical members 8 are mounted to both ends of the horizontal shaft portion 10a of this cross-shaped shaft 10 so as to be vertically rotatable.

Therefore, according to this embodiment, in the use position of the handrail main body 6, as shown in FIGS. 3a and 3b,
By engaging the lower part of the vertical member 8, that is, the locking part 11 in a pinched state with the locked part 9 of the bracket 2, its horizontal rotation is prevented, and when it is not in use, it supports the handrail main body 6. Lift the tip of the rod 1 upwards, as shown by the chain line in Figure 3b,
When the engagement between the locking portion 11 and the locked portion 9 is released by rotating the vertical member 8 vertically upward around the horizontal shaft portion 10a of the cross-shaped shaft 10, the support rod 1 is moved upward and downward from the cross-shaped shaft 10. Horizontal rotation is possible with the end as the rotation center, and in this state, the handrail main body 6 can be horizontally rotated and moved to the storage position.

Note that the support rod 1 may be made of any suitable material such as stainless steel, or may be made of a steel pipe 12 whose outer surface is coated with a synthetic resin coating 13, as shown in FIG. In this case, the gripper 1 is fitted into the steel pipe 12 by the cone portion 14b of the joint material 14a, and the bolt 14c is screwed into the gripper 1.
By expanding the expansion piece 14e of 4d and increasing the contact pressure between the inner wall surface of the steel pipe 12 and the outer periphery of the expansion piece 14e to connect the support rod 1 and the vertical member 8, a beautiful and beautiful connection can be achieved. A highly strong connected state can be obtained.

FIG. 5 is a perspective view showing a second embodiment of the present invention. In this embodiment, the upper proximal end of the support rod 1 is rotatably connected to a rotor 16 that is rotatable about a bolt 15, as shown in FIG. 6a, and is perpendicular to the bracket 2. The bracket 2 is configured with a vertical holding member 17 erected at its lower end and having a cylindrical locked portion 9 having a truncated conical guide portion at its tip. By engaging a locking portion 11 formed in the lower proximal end of the rod 1 with a locked portion 9, the handrail main body 6 is held in its use position.

Therefore, according to this embodiment, by vertically rotating the handrail main body 6 as shown by the chain line in FIG. can be horizontally rotated around bolt 15.

In this case, the manner of connection between the handrail main body 6 and the bracket 2 is not limited to that shown in FIG. 6a, but as shown in FIG. The auxiliary tool 18 equipped with the bush 18b is attached to the top, and the vertical shaft 19 and the spherical bush 1
