Abstract

PROBLEM TO BE SOLVED: To easily improve the external appearance in an appropriate bending angle, by connecting one handrail and the other handrail at the respective ends through a connecting member by which the bending angle can be varied. SOLUTION: Columnar stairs-handrail members 10 are connected to each other by use of a connecting member 11 therebetween. On connecting them, fitting plane bodies 12 are fixed to respective end faces of stairs-hand rail members 10 with screws 17. Basal bodies 15 are fixed respectively so as to fit a fitting boss 13 projecting from respective fitting plane bodies 12 and connect to each other through an intermediate body 16. When the inclined angle of stairs is small, a long intermediate body 16 is used, that is, the connection member 11 is used in the prolonged state as a whole. To the contrary, when the inclined angle is large, a short intermediate body 16 is used, or the connection member 11 is used in the contracted state as a whole. In this way, a holded angle corresponding to the inclination of stairs can be obtained.

2. Description of the Related Art FIG. 18 shows the arrangement of handrails on stairs. The staircase handrail 1 is arranged along the staircase 2, and in the example shown here, the staircase handrail 1 has three linear handrail members 3a,
3b, 3c and two connecting members 4 for connecting between them
a and 4b. As the connecting member 4a, one that bends 90 ° in a plane position is used, and as the connecting member 4b, one that has an appropriate bending angle (125-145 °) corresponding to the inclination angle of the stairs (35-55 °) is used. ing.

As shown in FIG. 19, the above-mentioned connecting member 4b is obtained by cutting the curved columnar member 4 at an appropriate position on site, and is cut at the x, y, z positions. The bending angle that gradually increases with is obtained.

[0004]

However, as described above, it is very troublesome to cut a member at a correct position in the field so that a desired bending angle can be obtained. It is very difficult to cut so that it faces the end surface of the handrail member when connecting,
If not cut properly, there was a problem that a gap was created in the connecting part or that the connecting part was distorted.

The present invention has been made in view of such a point, and an object of the present invention is to make it possible to easily connect a handrail at a bent portion at an appropriate bent angle with good appearance.

[0006]

In order to achieve the above object, in the invention according to claim 1 of the present invention, one end of each of the handrail members and the other handrail member are connected by a connecting member having a variable bending angle. It was configured to do.

According to the second aspect of the invention, the handrail connecting structure according to the first aspect is adopted in the handrail for stairs.
