In the base member 1 according to this embodiment, an edge 9 which forms a substantially circular opening smaller in diameter than the shaft hole 4 is formed at the opening edge on the plane side of the shaft hole 4. Also,
The female screw hole 6 is not formed.

The coupling member 2 has a guide portion 10 and a shaft portion 11, and the diameter of the shaft portion 11 is such that it can be inserted into the opening formed by the edge 9, and the shaft member 11 is in a state of being inserted. The length is formed to be flush with the inner edge 9 a of the edge 9. A female screw hole 19 is formed in the center of the shaft 11 from the bottom side.

The support member 3 is formed in the same manner as in the first embodiment.

Hereinafter, a handrail mounting structure using the mounting tool according to the third embodiment configured as described above will be described with reference to a handrail application procedure.

First, the connecting member 2 is attached to the base member 1. Specifically, the shaft portion 11 of the coupling member 2 is inserted into the shaft hole 4 of the base member 1, and a washer 20 and / or a spring washer 21 are inserted into the female screw hole 19 of the coupling member 2 from the bottom side of the shaft hole 4. Screw 1 as an intervening locking means

Attached to.

Subsequently, the base member 1 to which the connecting member 2 is attached is fixed at a predetermined position on the wall surface W which is the end of the handrail H. At this time, the bottom side of the base member 1 is aligned with the wall surface W, and a fixing screw 8 as fixing means is inserted into the insertion hole 5 and screwed into the wall surface W, so that the base member 1 is at a predetermined position on the wall surface W. Fixed. The fixing screw 8 forms a countersunk head, and when the base member 1 is fixed to the wall surface W,
It does not sink into the sinking portion 5a and does not protrude to the flat surface side (the mounting surface 30 side) of the base member 1.

Here, the coupling member 2 is attached to the base member 1 with a locking screw 14 'via a washer 20 and / or a spring washer 21. That is, the coupling member 2 slides on the mounting surface 30 of the base member 1 via the shaft portion 11 and the shaft hole 4 even though the coupling member 2 is sufficiently fixed to the base member 1 by screwing the locking screw 14 ′. It is rotatable in contact with it.

Subsequently, the support member 3 is attached to the connecting member 2. Specifically, the connecting portion 15 of the support member 3 is inserted into the guide portion 10 of the coupling member 2, and the insertion hole 1 of the support member 3 is inserted.
6 and the set screw 18

When attaching the support member 3 to the coupling member 2, the insertion port 1 of the support member 3
7, the support member 3 and the handrail bar H are attached together with the end of the handrail bar H inserted as shown by a two-dot chain line in FIG.

Subsequently, the support member 3 is rotated together with the connecting member 2 through the shaft 11 with respect to the base member 1 so that the direction of the insertion port 17 of the support member 3 and the direction of the attached state of the handrail rod H are changed. Adjust to fit.

Further, when supporting and fixing both ends of the handrail rod H with the above-mentioned attachments, the base member 1 and the coupling member 2 of each attachment are attached as described above, and the support member 3 of one of the attachments is attached. Is attached to the coupling member 2, one end of the handrail rod H is inserted into the insertion port 17, and the other end of the handrail rod H is inserted into the insertion port 17 of the support member 3 in the other mounting tool, and the support member 3 is inserted. After attaching to the joining member 2,
What is necessary is just to adjust the direction of each support member 3.

Incidentally, the support member 3 can be inserted so as to slide from the back side of the guide section 10 to the front side (indicated by an arrow in the drawing) with the connecting section 15. When the base member 1 is fixed at a predetermined position on the wall surface W, the connecting member 2
Front side of the guide portion 10 at (the surface which is formed in an arc shape)
May be turned in the direction in which the handrail H is to be attached, and the coupling member 2 may be rotated so that each side surface of the guide unit 10 and the axis h of the handrail H are parallel in plan view. Therefore, the support member 3 is configured such that the connecting portion 15 and the insertion port 17 are both open to the front side, and thus each side surface of the guide portion 10 is parallel to the axis h of the handrail bar H as described above. In this case, the guide 17 is guided along the axis h (longitudinal direction) of the handrail bar H with the opening of the insertion port 17 facing the end of the handrail bar H. The support member 3 is attached so that the insertion port 17 is inserted.

As described above, when the handrail is constructed, the base member 1 is positioned and fixed in advance, and the connecting member 2 is rotated with respect to the base member 1. After the supporting member 3 is attached while supporting the end portion thereof, the connecting member 2 is rotated to adjust the direction of the supporting member 3 so as to match the attaching direction of the handrail rod H.
The handrail can be easily and reliably applied.

Further, the supporting member 3 is
Since the configuration is such that the end of the handrail H is inserted and slidably mounted in the opening direction of the insertion port 17, the connecting member 2 is oriented with respect to the base member 1 with respect to the direction of the handrail H (the axis h ), The supporting member 3 can be attached so that the insertion port 17 is inserted into the end of the handrail rod H.
In addition, it is possible to reliably apply the handrail.

When the handrail is applied, the base member 1, the coupling member 2 and the support member 3 have the same circular outer diameter, and there is no unnecessary projecting or projecting portion. Therefore, the handrail can be installed as if the end of the handrail rod H is bent and attached to the wall surface W, and the design can be improved.

Further, in the state in which the handrail is installed, since the locking screw 14 for fixing the base member 1 and the coupling member 2 is disposed inside the shaft hole 4 of the base member 1, the handrail is not exposed. The only screws that come out are the set screws 18, and the design can be further improved.

Therefore, with such a handrail attachment and attachment structure, the construction work can be easily and appropriately performed, and the appearance of the construction state can be further improved.

In the first and second embodiments, the coupling member 2 may be attached to the base member 1 before attaching the base member 1 to the wall surface W.

In the first, second, and third embodiments described above, the coupling member 2 attached to the base member 1 includes the shaft hole 4 of the base member 1,
Although it is rotatable with the shaft portion 11 of the coupling member 2 inserted into the shaft hole 4, it is not limited to this, and there is a shaft portion on the base member 1 side and a shaft hole on the coupling member 2 side, The coupling member 2 may be configured to be rotatable with respect to the base member 1.

In the first, second and third embodiments described above, the guide portion 10 of the connecting member 2 is formed in a convex shape, and the connecting portion 15 of the support member 3 is formed in a concave shape. However, the present invention is not limited to this, and the guide portion 10 may be formed in a concave shape and the connecting portion 15 may be formed in a convex shape.

Furthermore, if the guide portion 10 and the connecting portion 15 are provided with irregularities which communicate with each other in the direction in which the insertion port 17 of the support member 3 is inserted into the guide portion 10 and the connection portion 15, the support member 3 can be attached to the coupling member 2 (guide Guide part 1)
0 and the connection part 15 can be locked. With such a configuration, for example, the hand is released in a state where the connecting portion 15 of the support member 3 is partially inserted into the guide portion 10 of the connecting member 2 and locked, and the free hand is used to hold the handrail rod H and hold the hand. Member 3
The end of the handrail H can be positioned at the insertion port 17 of the first member, and the supporting member 3 can be inserted into the coupling member 2 again, and work such as inserting the handrail H into the insertion port 17 can be performed.
Construction work can be further facilitated.

In the first, second and third embodiments described above, the support member 3 is configured to support the end of the handrail H. Alternatively, the insertion port 17 may be configured to communicate from the front side to the rear side so as to insert and support the intermediate portion of the handrail H.

In the first, second and third embodiments described above, the support member 3 has a single insertion port so as to support the end of the single handrail H. 17, but is not limited to this. For example, two insertion ports that open in opposite directions on the axis h of the handrail rod H, or one of the insertion ports is the axis of the handrail rod H A configuration having two insertion ports that open at a predetermined angle with respect to h may be employed.

As described above, if a support member having two insertion ports is formed, it is possible to construct a continuous handrail without a break. In particular, in the case where the floor continuously changes from a horizontal floor to an inclined floor, a support member having two insertion openings that open at the above-mentioned predetermined angle with respect to the wall surface of the portion where the inclination changes is provided. If it is adopted, it will be possible to always keep the same height from the floor and to construct a continuous handrail. At this time, if the two insertion ports are configured to be variably fixed at a desired angle, a handrail mounting tool having general versatility capable of responding to any inclination of the floor surface is obtained. It becomes possible.
