[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 to each other via a connecting member 1.

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

The threaded convex portion 20 is formed of a mounting plate 20a fixed to the end surface of the handrail member 2 with a screw, and a male screw portion 20b standing on the surface of the mounting plate 20a. Further, the threaded concave portion 21 is fixed to the end face of the handrail member 2 with a screw.
1a and a cylindrical portion 21 erected on the outer periphery of the bottom plate 21a
c, and a female screw portion 21b that is screwed with a male screw portion 20b formed on the inner peripheral surface of the tubular portion 21c.

The handrail connection work using the connection member 1 is performed as follows. First, at the construction site, the handrail member 2 is cut into a required length, and the screwed convex portion 20 is fixed to one end face of the handrail member 2 with a screw. Next, the threaded recess 21 is fixed to the end face of the other handrail member 2 connected to the handrail member 2 with a screw. 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 handrail members 2 together.

In this handrail connection structure, the threaded projection 20
Also, the handrail members 2 can be easily connected to each other by using the screwing recess 21.

[0007]

However, in the above-mentioned conventional handrail connection structure, the mounting plate 20a of the threaded projection 20 and the bottom plate 21a of the threaded recess 21 are closely fixed to the end surface of the handrail member 2. The other handrail member 2 is connected in the direction perpendicular to the end surface of the one handrail member 2. Since the end surface of the handrail member 2 is obtained by cutting the handrail member 2 on site, the handrail member 2 is not always cut at a right angle to the longitudinal direction of the handrail member 2.

Therefore, when the cut surfaces of both handrail members 2 are perpendicular to the longitudinal direction of the handrail member 2, both handrail members 2 are connected in a straight line, but as shown in FIG. 7 (b). ,
When the end surface of one of the handrail members 2 is not perpendicular to the longitudinal direction, the two handrail members 2 are not connected in a straight line, but are connected at an angle a corresponding to the angle of the end surface of the handrail member 2. When it is desired to connect the handrail members 2 in a straight line, the handrail members 2 must be cut at a right angle to the longitudinal direction of the handrail members 2, and there is a problem that this accurate cutting is troublesome.

The present invention has been made in view of the above circumstances, and an object thereof is to easily connect handrail members to each other even when the end faces of the handrail members are rough-cut and are not perpendicular to the longitudinal direction of the handrail members. The purpose of the present invention is to provide a handrail connection structure that can be connected directly to the handrail.
