Further, since the connecting base material 10 of the connecting member A is constituted so as to have a straight, that is, a straight, axial center line z which is not bent, the connecting base material 10 Handrail bars 40 can be assembled at both ends in a good shape so that their respective axial center lines are located on the same straight line.

The handrail bar 40 provided on the surface of the wall B in a connected state by the connecting member A can be attached to an object to be attached such as the wall B by various methods. Piece 42b, mounting seat 4
It is attached to an object to be attached such as a wall B using a bracket 42 provided with 2c or the like to constitute a handrail. The illustrated example shows an example of this, in which a handrail bar 40 is fixed to a support piece 42b of a bracket 42 with a screw or the like, and the bracket 42 is fixed to a mounting object such as a wall B with a screw 42d or the like. The attached configuration is shown.

The connecting tool A thus constructed can be applied to a handrail having a large number of bent parts, such as a staircase, a corridor, or the like, by means of the one type of connecting tool A. By connecting the handrails 40 in a bent state in the horizontal direction, or in a bent state in the vertical direction, or connecting the handrail bars 40 to each other so as to be in a single linear state, the object is effectively achieved. Handrail can be configured.

Further, by making the connecting base material 10 constituting the connecting member A made of wood, when connecting the wooden handrail bar 40, the appearance of the handrail bar 40 is not spoiled, and , Can be configured as a handrail having a handrail bar having the same good touch feeling.

[0060]

According to the present invention, there is provided a connecting device for a handrail bar.
A connecting base material having a linear axis center line, provided with a concave surface formed by a part of an imaginary spherical surface at both ends, and each imaginary surface passing through the opening edge formed by the respective concave surface. A connecting base material that is configured to gradually separate from one side toward the other side and has a hole communicating between the concave surfaces, and a part of a virtual spherical surface, and the concave surface in the connecting base material A pair of sets each having a convex portion provided at one end side so as to be able to make surface contact with the mounting portion, and having a mounting concave portion to which a handrail bar is mounted at the other end side, and having an assembling hole communicating the mounting concave portion and the convex surface portion. And mounting each of the mounting bodies on each of the concave surfaces of the connection base material such that the convex portion of the mounting body comes into contact with the concave surface, and mounting one of the mounting bodies. From the hole to the mounting hole of the other mounting body through the hole of the connecting base material Since the connecting base material and the respective assembled bodies are connected to each other at a freely selectable connecting angle by the attaching means passed therethrough, each handrail bar is made to be the same using one kind of the connecting tool. It can be connected so as to be installed on a straight line, and each handrail bar can be connected so as to be installed at an angle corresponding to the form to which the handrail is installed. In addition, it has a feature that the configuration of the handrail is easy.

Further, each concave surface at both ends of the connecting base material to which each of the assembled bodies is to be assembled is formed such that each virtual surface passing through the opening edge formed by the concave surface gradually moves from one side to the other side. Since it is configured to be separated, the opening edge of the concave surface on the side away from each virtual surface covers the convex surface portion of the assembled body connected in an angled state toward the opposite side. Due to the configuration, it has a feature that each handrail bar can be connected in a good form.
