DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a handrail fixture according to the present invention will be described below with reference to the drawings.

In this embodiment, a handrail P having a round bar shape is mounted on a mounting surface W formed by a wall surface.

In this embodiment, as shown in FIGS. 1 and 2, each of a receiving member 1 and a supporting member 2 connected by a connecting screw 3 is provided with a fitting structure 4 and a detent 5.

The receiving member 1 is formed in the shape of a curved plate piece and has a handrail P
A connection screw hole 12 is provided at the center of the handrail P, through which the connection screw 3 is inserted from the contact surface 11 that contacts the outer peripheral surface of the handrail P, and is screwed to the handrail P near both ends. Screw holes 13 and 14 through which the screws 6 to be inserted are inserted.

On the surface 15 opposite to the contact surface 11 of the receiving member 1, 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. The receiving member side portion 41 of the fitting structure 4 is formed so as to protrude from the surface 15 in a shallow (short axial length) cylindrical shape centering on the connection screw hole 12 (connection screw 3), and is formed outside the support member 2. It is structured to fit into. The end face 16 of the fitting structure 4, which is the back surface of the receiving member side portion 41 and the supporting member 2, is a plane orthogonal to the axis of the connecting screw hole 12 (the connecting screw 3). The receiving member-side portion 51 of the rotation stopper 5 is formed in a flat shape as a chord on the inner peripheral wall of the receiving member-side portion 41 of the fitting structure 4.

The support member 2 comprises a board-shaped mounting seat 21 abutting on the mounting surface W, and an arm 22 extending from the mounting seat 21 into a curved L-shape. In order to extend the mounting surface W to be mounted, the mounting seat 21 is provided with three relatively small-diameter first mounting holes through which screws 6 to be screwed and fixed when the mounting surface W is made of wood or the like are inserted. A screw hole 21a, and a relatively large-diameter second mounting screw hole 21b into which screws and bolts to be screwed and fixed when the mounting surface W is made of concrete or the like are inserted.
Are provided. A screw hole 22b into which the connecting screw 3 is screwed is formed in an orthogonal direction on a butted end face 22a of the arm 22 with the butted end face 16 of the receiving member 1.

Butt end face 2 of arm 22 of support member 2
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 around 2a. 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 planar shape corresponding to the receiving member side portion 51.

Further, in this embodiment, the support member 2
The first mounting screw hole 21a of the mounting seat 21 is
A cover 7 that covers the second mounting screw hole 21b and enhances decorativeness is fitted and mounted.

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

At the time of the butting of the fitting structures 4, the shallow cylindrical fitting structure 4 can be securely butted by covering the receiving member side portion 41 with the support member side portion 42 from above. Therefore, the connecting operation of 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 butting end surface 16 of the receiving member 1 and the butting end surface 22a of the arm 22 of the support member 2 are pressed against each other, so that a strong connection strength is obtained. . Also, the butted end face 16 of the butted receiving member 1 and the butted end face 22a of the arm 22 of the support member 2 are orthogonal to the axis of the connecting screw 3, and the connection between the receiving member 1 and the support member 2 is fitted. Since they are fitted by the joint structure 4, the mutual press contact force does not escape in the lateral direction (radial direction). Therefore, even if a load or the like is applied to the handrail P after the attachment, the connection between the receiving member 1 and the supporting member 2 does not become loose.

When the connecting screw 3 is tightened, the connecting screw 3
Are arranged at the center of the fitting structure 4, so that the connecting screws 3
Apply equally to the fitting structure 4. Therefore, the slide of the receiving member side portion 41 and the support member side portion 42 of the fitting structure 4 can be accurately performed, and the tightening of the connecting screw 3 can be performed smoothly.

When the receiving member 1 and the supporting member 2 are connected to each other, the rotation of the fitting structure 4 is prevented by the rotation stopper 5. Therefore, even if a load or the like is applied to the handrail P after mounting,
The connection between the receiving member 1 and the supporting member 2 does not become loose.
In addition, since the detent 5 is not formed as a separate member but 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 and extracting the connecting screw 3. Therefore, as shown in FIG. 5, the receiving members 1 having different dimensions and the like in which the fitting structure 4 and the rotation stopper 5 are shared can be used.

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 orthogonal to the axis of the connecting screw 3.

Further, the fitting structure 4 can be a fitting of a prism or a prism.

[0032]

As described above, the handrail mounting device according to the present invention slides the fitting structure by tightening the connection screw, so that the receiving member and the support member are perpendicular to the connection screw on which the tightening force effectively acts. However, since the joints are prevented from rotating unexpectedly by the rotation stop, the coupling strength between the receiving member and the support member is increased.

Furthermore, the receiving member and the supporting member are easily temporarily connected by the shallow fitting structure, and the receiving member and the supporting member are permanently connected by tightening the connecting screw, so that the connecting operation of the receiving member and the supporting member is easily performed. There is an effect.
