[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 7 (a) and 7 (b), there has been proposed a handrail connecting structure for connecting handrail members 2 via a connecting member 1. FIG.

The connecting member 1 has a threaded convex portion 20 screwed to one end face of the handrail member 2 to be coupled, a screwed threaded portion to the threaded convex portion 20, and a screw fixed to the other handrail member 2 end face. And a screw recess 21.

[0004] The screwing projection 20 is formed of a mounting plate 20a screwed to the end surface of the handrail member 2 and a male screw portion 20b provided upright on the surface of the mounting plate 20a. The screwing concave portion 21 is provided on the bottom plate 2 to be screwed to the end surface of the handrail material 2.
1a and a cylindrical portion 21 erected on the outer periphery of the bottom plate 21a.
and a female screw part 21b screwed with a male screw part 20b formed on the inner peripheral surface of the cylindrical part 21c.

[0005] The handrail connecting operation using the connecting member 1 is performed as follows. First, at the construction site, the handrail material 2 is cut to a required length, and the screwing projection 20 is fixed to one end of the handrail material 2 with a screw. Next, a screwing recess 21 is screw-fixed to the end surface of the other handrail member 2 connected to the handrail member 2. Then, the handrail member 2 having the screwing convex portion 20 is turned, and the screwing convex portion 20 is screwed into the screwing concave portion 21 to connect the both handrail members 2.

However, in the conventional handrail connecting structure, the mounting plate 20a of the screwing projection 20 and the bottom plate 21a of the screwing recess 21 are fixed to the end surface of the handrail material 2 closely. The other handrail 2 is connected in a direction perpendicular to the end face of one handrail 2. Since the end surface of the handrail 2 is obtained by cutting the handrail 2 at the site, it is not always cut at a right angle to the longitudinal direction of the handrail 2.

Accordingly, when each cut surface of the both handrails 2 is perpendicular to the longitudinal direction of the handrail 2, the two handrails 2 are connected in a straight line, but as shown in FIG. ,
When one of the end surfaces of the handrail 2 is not perpendicular to the longitudinal direction, the two handrails 2 are not connected linearly but are connected at an angle a by the angle of the end surface of the handrail 2. When connecting both handrails 2 in a straight line, both handrails 2 must be cut at right angles to the longitudinal direction of handrail 2, and there is a problem that this accurate cutting is troublesome.
