上記ストッパ２を解除して手摺主体ｌを回転可能とした
ものが提案されていた。Conventionally, so-called movable handrails in which the main body of the handrail is rotated from a use position to a non-use position have been constructed using a base end portion of a handrail main body 1 that is cantilevered and horizontally rotatable, as shown in FIG. It has been proposed to form a stopper 2 that restricts the horizontal rotation of the handrail main body 1, and to release the stopper 2 by lifting the handrail main body 1, thereby making the handrail main body 1 rotatable.

Since the bin 2a formed on the handrail main body 1 is configured to engage with the round hole 2b of the bracket 3 to restrict the horizontal rotation of the handrail main body 1, the above-mentioned bin 2a and the round hole 2b
The backlash required for engagement and disengagement due to the clearance caused a considerable amount of lateral vibration at the free end of the handrail main body 1. This lateral vibration not only deteriorates the image of the product as a whole, but especially when used in a toilet for the handicapped, it can cause a feeling of anxiety when the handicapped person tries to support their entire body weight with the handrail body. This had the problem of causing irritation.
本発明は、以上述べたような、従来の可動型手摺のスト

切欠を形成したことを特徴とする可動型手摺のストッパ
構造を提供することにより解決される。According to the present invention, the above-mentioned problem can be solved by having a stopper structure at the base end of the handrail main body, which is formed to be cantilevered and capable of at least horizontal rotation, for regulating the horizontal rotation of the handrail main body, and the above-mentioned problem is solved. In a movable handrail that enables horizontal rotation by releasing a stopper by lifting the handrail main body, when the handrail main body is provided with an engagement protrusion that is approximately trapezoidal in plan view, a bracket that supports the handrail main body is provided. This problem is solved by providing a stopper structure for a movable handrail, characterized in that a notch is formed having an angle of expansion that is substantially the same as the angle formed by the hypotenuse of the trapezoidal shape of the engagement protrusion.
上記ストッパ構造における係合突起は、手摺主体の使用
位置において、切欠の側縁と密着してくさび状に噛合す

を密着させて吻合できるようになっている。To explain the stopper structure of the present invention with reference to FIGS. 3 and 4, a locking protrusion 15 having a substantially trapezoidal shape in bottom view is attached to a side end of a locking member 14 attached to the lower end of the vertical member 6 of the handrail main body 1.
is provided to protrude downward, while the lower end of the bracket 3 is bent toward the handrail main body 1 side to form a locking plate portion 16. This locking plate part 16 has a semicircular part 18 whose center 17 is an extension of the axis of the vertical axis lO attached to the upper part of the bracket 3.
A stopper bin 19 is erected at the center of the semicircular portion 18, and a plurality of notches 20 are formed on the outer periphery of the semicircular portion 17 toward the center 17. The notch 20 widens outward at approximately the same angle α (see FIG. 4) formed by the hypotenuse of the trapezoidal shape of the locking protrusion I5, and the locking protrusion 15 widens outward at the angle α (see FIG. 4) formed by the hypotenuse of the trapezoidal shape of the locking protrusion I5. The edges can be brought into close contact for anastomosis.

過度にくい込むことが防止されている。On the other hand, a guide portion 21 is formed between the locking protrusion 15 of the locking member 14 and the reflective force, and the stopper bin 1 is attached to the guide portion 21.
9 is slidably fitted, and a stopper adjustment screw 22 screwed onto the vertical member 6 prevents the locking protrusion 15 from digging into the notch 20 excessively.

In addition to the engagement between the locking protrusion 15 and the notch 20, horizontal rotation is regulated by a reaction force at the abutment area between the stopper pin 19 and the guide portion 21, and the force for preventing rotation becomes large. Overall structural stability can be improved.

ととなる（第４図参照）。In this way, in the use position of the handrail main body 1, the locking protrusion 15 engages in the notch 20 (in a wedge-like manner) and its horizontal rotation is restricted.Therefore, from this state, the tip of the support rod 5 is lifted up. , the vertical member 6 rotates around the horizontal axis 9,
The engagement between the locking projection 15 and the notch 20 is released (see FIG. 3). Next, when the support rod 5 is pushed outward in the disengaged state, the locking member 14 horizontally rotates around the vertical shaft 10, and the vertical member 6 rotates around the axis of the vertical shaft 10 and the stopper bin 19. When the vertical member 6 forms a conical surface and rotates, and is further stacked in the unused position, the vertical member 6 automatically rotates around the horizontal axis 9 due to its own weight and the weight of the support rod 5, and the locking protrusion 15 is again engaged and held within the notch 20 (see FIG. 4).

Although the present invention has been described based on an embodiment, the present invention is not limited to what is described in this embodiment. For example, in terms of the structure of the movable handrail itself, the structure shown in FIG. 2 as a conventional example may be used. It is good even if it is. Further, the structure of the connecting portion between the handrail main body 1 and the bracket 3 is not limited to this embodiment, and may use a spherical bush 23, for example, as shown in FIG. 6.

ある。Further, in the embodiment, a plurality of notches 20 are formed so that the use positions can be set in multiple stages, but a total of two notches 20 are formed by specifying one use position and one non-use position. Alternatively, in order to determine only the use position of -MHI, only - pieces may be formed. Furthermore, it goes without saying that the guide part 21 is not necessary if the structure of the movable handrail itself does not require vertical rotation of the handrail main body 1, or if it does not require strict vertical rotation. Also, in the configuration for preventing overrun of the locking protrusion 15 due to contact between the stopper adjustment screw 22 and the stopper pin 19, the locking protrusion 15 sinks into the notch 20 and cannot be removed by appropriately selecting the material or the expansion angle a. It is not necessary to provide it when the risk has disappeared.

止することができる。As is clear from the above description, according to the movable handrail stopper structure of the present invention, the engaging protrusion formed at the base end of the handrail main body has a substantially trapezoidal shape in plan view, and the engaging protrusion has a substantially trapezoidal shape in plan view. By forming a notch in the bracket that has an expansion angle that is approximately the same as the angle formed by the hypotenuse of the trapezoid, when the engaging protrusion and the notch are engaged, the side edge of the engaging protrusion is aligned with the side edge of the notch. Since it is tightly engaged with the support rod in a wedge-like manner, no backlash occurs at all, and it is possible to completely prevent the support rod tip from swinging laterally due to this play.
