BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a handrail attachment according to the present invention will be described below with reference to the drawings.

In this embodiment, a round bar-shaped handrail P is mounted on a mounting surface W composed of a wall surface.

In this embodiment, as shown in FIGS. 1 and 2, a fitting structure 4 and a detent 5 are provided at respective portions of a receiving member 1 and a supporting member 2 which are connected by a connecting screw 3.

The receiving member 1 is formed in the shape of a curved plate piece and has a handrail P.
Is fixed to the handrail P by screwing the connection screw 3 through the contact surface 11 side of the handrail P that contacts the outer peripheral surface of the handrail P. The mounting screw holes 13 and 14 through which the screws 6 are inserted are provided.

A receiving member side portion 41 of the fitting structure 4 and a receiving member side portion 51 of the rotation stopper 5 are provided on the surface 15 of the receiving member 1 opposite to the contact surface 11. The receiving member side portion 41 of the fitting structure 4 is formed so as to project from the surface 15 in a shallow (short axial length) cylindrical shape centering on the connecting screw hole 12 (connecting screw 3), and outside the supporting member 2. It has a structure that fits in. In addition, the abutting end surface 16 with the support member 2, which is the inner surface of the receiving member side portion 41 of the fitting structure 4, is a flat surface orthogonal to the axis of the connecting screw hole 12 (connecting screw 3). The receiving member side portion 51 of the rotation stopper 5 is formed in a planar shape serving as a chord on the inner peripheral wall of the receiving member side portion 41 of the fitting structure 4.

The support member 2 is composed of a disc-shaped mounting seat 21 that abuts the mounting surface W, and an arm 22 that extends from the mounting seat 21 into a curved L-shape. To the mounting seat 21, in order to expand the mounting surface W to be mounted, when the mounting surface W is made of wood or the like, the screw 6 that is screwed and fixed is inserted into the mounting seat 21 for the three relatively small diameter first mountings. One relatively large diameter second mounting screw hole 21b into which the screw hole 21a and a screw or bolt to be screwed and fixed when the mounting surface W is made of concrete or the like is inserted.
And are provided. A screw hole 22b into which the connecting screw 3 is screwed is formed in the butt end surface 22a of the arm 22 with the butt end surface 16 of the receiving member 1 in the orthogonal direction.

Butt end face 2 of arm 22 of support member 2
Around the 2a, a support member side portion 42 of the fitting structure 4 and a support member side portion 52 of the rotation stopper 5 are provided. The support member side portion 42 of the fitting structure 4 is formed in a cylindrical shape that fits inside the receiving member side portion 41. The support member side portion 52 of the rotation stopper 5 is formed in a cylindrical notched plane shape corresponding to the receiving member side portion 51.

Further, in this embodiment, the support member 2
To the mounting seat 21 of the first mounting screw hole 21a of the mounting seat 21,
The cover 7 for covering the second mounting screw hole 21b and enhancing the decorative property is fitted and mounted.

According to this embodiment, the receiving member 1 and the supporting member 2 are temporarily connected by abutting the fitting structure 4, and the receiving member 1 and the supporting member 2 are permanently connected by tightening the connecting screw 3. .

When the fitting structure 4 is butted, the receiving member side portion 41 is put over the support member side portion 42 from above so that the shallow cylindrical fitting structure 4 is surely butted. Therefore, the work of connecting the receiving member 1 and the supporting member 2 is easy.

When the connecting screw 3 is tightened, the fitting structure 4
The receiving member side portion 41 and the supporting member side portion 42 slide, and the abutting end surface 16 of the receiving member 1 and the abutting end surface 22a of the arm 22 of the supporting member 2 come into pressure contact with each other, so that a strong connection strength is obtained. . Further, the abutting end surface 16 of the receiving member 1 and the abutting end surface 22a of the arm 22 of the supporting member 2 that are butted are orthogonal to the axis of the connecting screw 3, and the receiving member 1 and the supporting member 2 are connected together. Since the mating structure 4 is fitted, the pressure contact forces do not escape in the lateral direction (radial direction). Therefore, even if a load or the like is applied to the handrail P after attachment, the connection between the receiving member 1 and the supporting member 2 does not loosen.

When tightening the connecting screw 3, the connecting screw 3
Is located at the center of the fitting structure 4, so that the connecting screw 3
The tightening force of is evenly applied to the fitting structure 4. Therefore, the receiving member side portion 41 and the supporting member side portion 42 of the fitting structure 4 can be accurately slid to smoothly tighten the connecting screw 3.

Further, when the receiving member 1 and the supporting member 2 are connected, the rotation of the fitting structure 4 is blocked by the detent 5. Therefore, even if a load is applied to the handrail P after mounting,
The connection between the receiving member 1 and the supporting member 2 does not loosen.
Since the detent 5 is not formed as a separate member and is formed integrally with the fitting structure 4, the structure around the fitting structure 4 and the detent 5 is simplified.

The connection between the receiving member 1 and the supporting member 2 can be easily released by loosening the connecting screw 3 and pulling it out. Therefore, as shown in FIG. 5, it is possible to exchange and use the receiving members 1 having different sizes and the like in which the fitting structure 4 and the detent 5 are made common.

As described above, in addition to the illustrated embodiment, the contact surface 11 of the receiving member 1 may have an inclination angle other than the right angle with respect to the axis of the connecting screw 3.

Further, the fitting structure 4 may be a prism or a prism.
