Abstract

PROBLEM TO BE SOLVED: To provide a connecting structure with a spherical body interposed on a connecting part of handrail materials 14 capable of arranging the handrail materials by twisting them. SOLUTION: The both handrail materials 14 are connected to each other by holding the spherical body 11 by both of receivers 12, 13 by connecting the handrail materials 14 to the other ends of the receivers 12, 13, fitting a semispherical recessed surface 12a of the one receiver 12 on one side of the spherical body 11, fitting a semispherical recessed surface 13a of the other receiver13 on the other side of the spherical body 11 and fixing the both handrail materials 14 on a wall surface, etc. As the spherical body 11 is held by the receivers 12, 13 only but the spherical body 11 and the handrail materials 14 are not connected to each other, it is not only possible to arrange the both handrail materials by being them at optional angles at a part of the spherical body 11 but also possible to connect them even when the handrail materials 14 are twisted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining structure of a handrail, and more particularly, to a joining structure in which a sphere is interposed at a joining portion between a handrail and a handrail.

[0002]

2. Description of the Related Art As one type of a joining structure of a handrail material, Japanese Patent No. 3043617 discloses a method in which a pair of hollow hemispheres that are combined into a sphere are provided, and a ring-shaped convex portion is provided on the opening end face of one hemisphere. A ring-shaped recess is formed on the opening end face of the other hemisphere to be fitted with a projection, and a screw member is fixed to each hemisphere. Each hemisphere is connected to a handrail by a screw member, and the projection and the recess are formed. Are disclosed, and a joining structure in which both hemispheres are connected spherically is disclosed.

[0003]

In the above-mentioned conventional joint structure, the bending angle of both handrails can be freely set within a plane including the fitting surface of both hemispheres. The handrail material cannot be twisted and attached in a direction deviating from the plane including the mating surface. Therefore, when attaching the handrails, care must be taken so that the two handrails are not twisted with each other, and the attaching work is extremely troublesome. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a joining structure which can not only bend both handrails freely at a spherical portion but also join even if the handrails are twisted.

[0004]

According to a first aspect of the present invention, there is provided a joining structure for a handrail material, comprising: a sphere; and a pair of receiving members each having a hemispherical concave surface at one end. A handrail material is connected to the other end of the sphere, a hemispherical concave surface of one receiver is fitted to one side of the sphere, a hemispherical concave surface of the other receiver is fitted to the other side of the sphere, and The sphere is held by the receiving members by fixing both handrails to a wall surface or the like.

[Action and Effect of the Invention]

According to the present invention, since the sphere and the handrail are not connected only by holding the sphere by the receiving member, not only can both handrails be bent at an arbitrary angle at the sphere but also the handrail can be arranged. Joining is possible even if the material is twisted. Therefore,
The work of attaching the handrail material is facilitated, and the construction efficiency is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIGS. 1 to 4 show a handrail material joining structure according to an embodiment of the present invention. The joining structure 10 is
One sphere 11 and a pair of receiving members 12 and 13 are provided.

Each of the receiving members 12 and 13 has, at one end, a hemispherical concave portion 12a, 13a having substantially the same radius of curvature as the sphere 11, and the open end surfaces 12b, 13a of the concave portions 12a, 13a.
b is cut diagonally. In addition, receiving parts 12, 13
Are formed at the other end thereof with concave portions 12c and 13c having a circular cross section,
Holes 12d and 13d are formed to communicate the hemispherical concave portions 12a and 13a with the circular concave portions 12c and 13c.

The handrail member 14 has one end formed with a circular recess 12.
c, 13c, and a screw 15 is screwed into the handrail member 14 from the hemispherical concave portions 12a, 13a through the holes 12d, 13d, and the handrail member 14 and the receiving members 12, 13 are integrally fixed.

When the handrail member 14 is installed, one of the handrail members 14 to which the receiving member 12 is fixed is fixed to a wall surface by a bracket 15. Then, one side of the sphere 11 is fitted to the receiving member 12. Then, the receiving member 13 of the other handrail member 14 is attached to the sphere 1
The other handrail member 14 is fitted so as to bend at a required angle with respect to the one handrail member 14 in this state, and is fixed to a wall surface with a bracket 16. In this way, the sphere 11 is held by the receiving members 12 and 13.

FIG. 2 shows a state in which the both handrails 14 are attached in parallel with the wall surface (in FIG. 2, in parallel with the plane of the paper) and the two handrails 14 form a right angle. FIG. 3 shows a state in which the both handrails 14 are attached in parallel with the wall surface (in FIG. 3, parallel to the paper surface) and at an angle of about 135 degrees.

In the handrail joint structure 10 according to the present embodiment, the sphere 11 is only held by the receiving members 12 and 13, but the sphere 11 and the handrail 14 are not connected. Therefore, as shown in FIG. Alternatively, the joining can be performed in a state where the other handrail member 14A is twisted with respect to the one handrail member 14 (in FIG. 4, the handrail member 14A is inclined in a direction intersecting the paper surface). For this reason, the work of attaching the handrail members 14 and 14A is facilitated, and the construction efficiency is improved.
